A41d .Z3/10, 19/00 U.S. Cl. 2 161 3 Claims ABSTRACT OF THE DISCLOSURE A fireplace glove made of two telescopically interiitted glove-shaped parts, the outer glove part being made of expanded leather and the inner glove part of wool fabric. The two intertted parts of the-glove are respectively provided with wrist-embracing cuff portions having their open ends perimetrally sewn together by lines of stitching which serve as the sole means of securement of the inner glove part to the outer glove part in consequence of which the palm and linger portions of the interitted glove parts are free to move relatively to one another to preclude build-up of heat at any one point in the glove. The expanded leather of the outer glove part and the wool fabric of the inner glove part are both surface-napped to create air cells or pockets in which air is entrained as the medium for retarding conduction of heat through the superimposed leather and wool layers of the glove. The palm portion of the leather glove part is internally lined with a porous fabric to physically separate the palm portions of the intertted glove parts, which lining being thus interposed between layers of iire resistant materials may or may not be ammable per se.

This invention relates to fireplace gloves and more particularly to improvements in the construction thereof to effectively protect the hands of the wearer against injury in the handling of extremely hot objects such as burning logs and coals in fireplaces and briquettes in charcoal broilers or grilles.

Among the principal objects of the present invention is the provision of a glove having an outer shell of leather in which is more or less loosely intertted an inner gloveshaped shell fabricated of a napped coarsely woven wool material, the interiitted inner and outer shells being provided in the areas thereof which overlie the palm and inside surfaces of the thumb and fingers of the wearers hand with an insulating cushion of a porous fabric.

All of the materials of which the glove is formed have a high degree of porosity to provide therein a myriad of air cells or pockets in which air is entrfained as the heat insulating medium for preventing transference of extreme heat from the heated object being handled to the hand upon which the glove is worn. Thus, an important aspect of the invention is to provide such telescopic assembly of an outer glove formed of expanded leather and an inner glove separately formed of a coarsely woven 100 percent wool fabric, with an intervening cushioning layer of a porous fabric disposed therebetween, to effectively utilize as the heat insulating medium the air which is entrapped within and between each superimposed fabric layer of the love. g An important objective of the invention is to so attach the inner woolen fabric glove within the outer leather shell thereof as to permit the inner glove such freedom of movement within its encasing shell of leather as to prevent the build up at any one point in the glove of heat transferred from a heated object being handled.

A further object of the invention is to provide a glove of the character above described wherein the several materials of which the outer and inner gloves are formed are disposed in such specific relation to one another as to most effectively provide maximum protection against inice jury of the wearers hand in handling heated objects, as well as to reduce to a minimum cuts and punctures of the glove such as might be occasioned by sharp and abrasive objects.

Still another important object of the present invention is to provide a multiple-layered glove which is so pliant and flexible when fitted on the hand as to be convenient in use and yet provide an extremely tough outer surface for maximally resisting cuts, punctures and abrasions without at the same time reducing its tire resistant and heat insulating properties.

A still further object of the invention is to provide a fireplace glove having an outer surface of expanded leather which in itself retards conduction of heat therethrough and which is not subject to such hardening and shrinking as to prematurely shorten the useful life of the glove.

It is also an important object of the invention to provide a glove fabricated of materials all of which are adapted to be dry-cleaned without reducing its eectiveness for safely protecting the hand against burns and other injury during the handling of heated articles.

Other objects and advantages of the present invention will appear more fully hereinafter, it being understood that the invention consists substantially in the combination, construction, location and relative arrangement of parts as hereinafter described as shown in the accompanying drawings and as finally pointed out in the appended claims.

In the dr-awings:

FIG. 1 is a perspective view of the glove constructed in accordance and embodying the principles of the present invention;

FIG. 2 is a longitudinal sectional view of the glove as taken along the line 2 2 of FIG. 1;

FIG. 3 is a longitudinal sectional view of the thumb and foreiinger section of the glove as taken along the line 3 3 of FIG. 1;

FIG. 4 is a transverse sectional view of the palm and thumb section of the glove as taken along the line 4 4 of FIG. 1;

FIG. 5 is a transverse sectional view through the linger portions of the glove as taken along the line 5 5 of FIG. 1;

FIG. 6 is an exploded view showing in perspective individually formed outer and inner parts of the glove prior to their telescopic assembly to form the completed glove of FIG. 1;

FIG. 7 is an exploded view showing in plan the several individual component elements of the outer part of the glove;

FIG. 7A is a view of the glove part as formed of the components of FIG. 7; and

FIG. 8 is an exploded view showing in plan the several individual component elements of the inner portion of the glove.

Referring now more particularly to the drawings, it will be noted that the completed glove 10 as shown in FIG. 1 comprises essentially a pair of telescopically interlitted outer and inner glove-like parts 11 and 12 respectively shown in FIG. 6, The outer part 11 of the glove is provided with an external sheathing 13 of expanded leather having its inner `face in the regions of the palm and finger portions of the glove lined with a porous fabric 14 to provide an insulating cushion between the interiitted inner and outer parts 11 and 12 of the glove.

The expanded leather constituting the outer sheathing of the glove part 11 is commercially available in the form of split leather at least 3A@ inch thick in which the fibres have been so separated and raised by chemical or rnechanical means as to provide a myriad of air pockets which serve to insulate the raised libres of the leather from one another. Such expanded leather not only retards conduction of heat therethrough, but also resists hardening and shrinking of the leather to thereby increase the pliability and useful life thereof.

Although the mode of prodcing the expanded leather forms no part of the present invention, it may be mentioned that such expanded leather may be prepared in several ways, one of which involves scoring and teasing up the surface of the leather, as in napping iiannel, then tanning the teased leather With `chromium sulphate, oiling it with sperm oil and finally spinning it in a rotating bathed drum until the leather reaches a desired degree of softness. In certain instances, the leather may `be initially soaked in a solution of 50% boric acid and 50% borax for a period of 100 to 120 hours prior to the teasing step, while in still other instances the teasing or napping step may be performed after the leather has been tanned, oiled and drummed.

FIG. 7 illustrates the pattern of cutting the expanded leather 1.3 in fiat or sheet form for producing a glove for the right hand, it being observed that the cutting is such as to provide a main part which is adapted to overlie the palm of the right hand and the inner surfaces of the four lingers thereof, and independently cut out parts 16, 17 and 18 to respectively cover the back or outer surfaces of the middle, ring and little fingers of the hand. The main part 15 additionally includes a laterally extending reversely foldable wing portion 19 to cover the back or outer surface of the index finger of the hand and also a freely extending portion 20 to overlie the inner surface of the thumb. Still another separately cut out part 21 of the expanded leather is provided to cover the back or outer surface of the thumb.

The porous fabric 14, which may be woven or knitted of any suitable fibrous yarn, such as wool, cotton and the like, is cut to the shape and forni best shown in FIG. 7, and is stitched, as by the line of stitching 22, to the inner face of the main part 15 of the expanded leather to provide the latter with a fixed inner lining of porous cushioning material -for the palm, finger and thumb portions thereof.

With the lining stitched in place as shown in FIG. 7, the wing portion 19 of the main leather piece 15 is folded back over the unlined surface of the index finger portion 23 to present its perimetral edges in registry with the corresponding edges of said linger portion 23 of the piece 15, following which the registering edges of the corresponding index nger parts are stitched together along the line 24 to form the index finger of the glove part 11.

Thereafter, the several separately formed finger pieces 16, 17 and 18 of the expanded leather are respectively positioned in backtoback overlying relation to the unlined surfaces of their corresponding finger portions of the main leather piece 15, following which the corresponding parts for each of the glove fingers are stitched together along their edges, as by the lines of stitching 25, 26 and 27 for the middle, ring and little fingers respectively. Finally, with the thumb portion 20 of the main leather part 15 folded back over the palm portion thereof so as to present in face to face relation the surfaces thereof lined with the porous insulating fabric 14, the separately cut out thumb piece 21 is positioned over the unlined surface of the thumb portion 20 and stitched thereto along the stitch line 28 to form the thumb of the leather glove part 11.

The above described procedure for stitching together the several component elements of the leather glove part 1l is preferred since it facilitates easy machine sewing of the relatively heavy leather fabric. It will be apparent, however, that this procedure results in an inside out formation of the glove part, that is, `with its cushioning lining 14 and the sewed edges thereof externally exposed. Thus, after the leather glove part 11 has been formed as described, it is turned inside out so that its stitched edges and the lining 14 thereof are disposed internally of the glove.

It will be understood, of course, that any other suitable procedure may be followed for producing the leather glove part 11 and also that in lieu of forming the same with the thumb and several finger parts as shown, it may be formed as a mitten having a single part for commonly receiving the several fingers of the hand in addition to that for receiving the thumb.

Upon completion of the hand-embracing portion of the leather glove part 11, it is provided with a wrist-embracing cuff 29 formed of the cuff pieces 30-31 cut out of any suitable leather stock which may or may not be expanded leather. These cuff parts 30-31, which are stitched along the stitch lines 32 to complete the leather glove part 11, may be sewn in position eitner before or after the handembracing part of the leather glove is turned right side out. Also, if desired, the cuff 29 may be provided with a loop hanger strap 33.

The inner glove part 12 is formed of a coarsely woven napped wool fabric which is cut according to a predetermined pattern into the several parts 34, 35, 36, 37 and 38 which are then sewn together along the stitch lines 39 to produce the completed inner glove part as shown in FIG. 6. For this construction of the inner glove 12, the parts 34 and .35 are simply superimposed upon one another with -their corresponding palm and linger edges in registry and with the separate thumb part 36 superimposed upon the -turned back thumb portion 36a of the part 35 to present their correspondinv edges in registry, whereupon the registering edges are all stitched together as will be readily understood. As in the case of the outer expanded leather glove part 11, the inner glove is also provided with a Wristembracing cuff 39 formed of the cuff parts 37 and 38, which latter are of wool fabric. It will of course be understoood that the woolen inner glove part may be of mitten form in those instances where it is to be telescopically fitted into an outer expanded leather glove part produced in the form of a mitten.

While both the palm and back faces of the inner glove part are formed of coarsely woven percent wool fabric having a napped surface to increase its surface porosity and thereby its air entraining capability, the wool fabric forming the back face of this inner glove part is preferably provided with a knitted backing having a coarsely interwoven napped facing of 100 percent wool. This woolfaced knitted fabric is also preferably employed for the thumb part 36. By constructing the inner glove part 11 so that the knitted backing of the wool-faced fabric is exposed on the back face of the glove and on the back face of the thumb portion thereof, telescopic insertion of the woolen glove part 12 into the leather outer glove part 11 to form the complete glove shown in FIGS. l to 5 is facilitated.

Upon insertion of the wool inner glove part 12 into the outer expanded leather glove part 11, the two parts so telescoped into one another are secured together solely by the line of stitching 40 extending peripherally about the outer open cuff ends of the two glove parts. Thus, the inner glove is secured in relatively free-floating arrangement within the outer glove so that its finger, thumb and palm parts have such freedom of movement within the outer leather glove as to preclude the possibility of heat being built up at any one point of contact of the glove with a heated object.

It will be understood, of course, that the glove may be fashioned as hereinabove described for either or both left and right hands, and that the essential aspect of the glove construction is to produce the same of such materials as have been described in such relative arrangement as to create between the contiguous layers of the inner and outer glove parts cellular air spaces which effectively provide insulation against extreme heat. Since the glove of the present invention depends basically upon the air entrapped in the interstices of the napped materials as the heat insulating medium, it will be apparent that the inherent flexibility of these materials is in no way reduced by the entrapped air and thus the glove is highly pliant and flexible when fitted upon the hand despite the fact that it comprises, as described, a pair of separately formed telescopically interfitted inner and outer glove parts.

It will be understood that the porous fabric 14 which internally lines the palm and inside finger and thumb faces of the expanded leather glove part 11 serves primarily as a mechanical separation between the inner and outer glove parts and that since it is sandwiched between two materials which are each themselves highly re resistant, it may or may not be ammable per se. However, due to its porous character this lining 14 also serves effectively to entrap air for preventing the transfer of heat from the outer leather glove part 11 to the inner woolen glove part 12.

It will be understood further that the present invention is susceptible of various changes and modifications which may be made from time to time without departing from the real spirit or principles thereof, and it is accordingly intended to claim the invention broadly, as well as specifically as indicated in the appended claims.

What is claimed as new and useful is:

1. A fireplace glove comprising in combination, an outer glove part of leather, and an inner glove part of woolen fabric, each of said glove parts constituting a complete enclosure for the hand of the wearer with the inner glove part telescopically fitted within the outer glove part, the said outer and inner glove parts being respectively provided with wrist-embracing cuff portions having open ends in registry with one another and secured together peripherally about said registering open ends thereof whereby the hand-embracing portion of the inner glove part is free to move relatively to the corresponding portion of the outer glove part, said outer leather glove part being provided in the areas thereof which overlie the palm and corresponding faces of the thumb and fingers of the hand with a fixed-imposition lining of porous fabric which serves as an insulating cushion between the layers of the telescopically interfitted outer and inner glove parts.
