or more narrow widths or pieces of double pile fabrics being woven side by side in a broad loom, and to admit of their being afterward divided the one from the other to produce two or more narrow widths, each with fast selvages. For this purpose we form two adjacent selvages with fast edges at any desired part of the width both of the upper and lower cloths of the double pile fabric, and we form the selvages in the upper cloth immediately above the selvages in the lower cloth. To form a fast edge to each inner selvage, we
' employ awarp binding-thread to cross with the outermost warp of the selvage and become knit together therewith. Any desired number of fast inner selvages may be formed in this Way in the width, so that the fabric may be divided into widths ofauy required size by cutting both the upper and lower cloths lengthwise in between the pairs of fast selvage edges which have been made in these cloths.
To form two adjacent fast inner selvages both in the upper and lower cloth of a double pile fabric, and to form the fast selvage edges in the upper cloth immediately above the fast selvage edges in the lower cloth, we employ two sets of needles of two needles each. The needles in the upper set we place in a line with the needles in the lower set, and make them to point downward, while those in the lower set we make to point upward. Both sets of needles we fix in slides, which can be simultaneously moved either upward or downward in a fixed frame, and to give motion to the slide, we connect them by a rod to a heald-lever. The needles, near to their points, have eyes formed through them, and through the eyes of the upper pair we thread the bindingmovement can be given from the low shaft.
Through the upper pair we pass two selvagewarps for the upper cloth, and through the cloth. These two pairs of eyes are set one A above the other at such a distance apart as to leave space enough for a shuttle to pass to and fro between the warps threaded through them. The points of the upper pair of needleswe likewise set at a distance from the points of the lowerpair ofneedles. In theupward and downward movement of the needles their points are brought alternately above and below the selv age warp-threads with which the bindingthreads threaded through the needles are-to be crossed, and when the needles are at one or the other end of their stroke the threadeyes are made to shog sidewise, so that the Warp binding-threads, which receive an upand-down motion, may, as hereinafter more fully described, be first brought to one side and then to the opposite side of the warps, which receive a sidewise movement, and the binding-threads and warpsare so twisted together with a false twist, which, in conjunction-with the weft-threads, link them together and form a fast selvage edge.
In the drawings hereunto annexed we have shown two constructions of mechanism for forming fast inner selvages in the two cloths of a double pile fabric in themanner above described. One construction is adapted for formingthe fastinner selvagesin the two cloths when the fabric is being woven in a single-shuttle loom, and the other for forming these selvages when the fabric is being woven in a loom in which two shuttles are thrown simultaneously.
Figures 1 to 5 show the mechanism to be used with a single-shuttle loom Fig. 6 shows a longitudinal section of some of the main parts of a single-shuttleloom and the mechanism for forming the fast inner selvages fitted to it, in order to show clearly the way in which this mechanism is controlled from the low or picklower pair two selvage-warps for the lower ing shaft of the loom. Figs. 7 and 8 show the mechanism to be used with the two-shuttle loom. Fig. lis a side elevation of mechanism to be used with a single-shuttleloom for forming the fast inner selvages in the two cloths of a double-pile fabric, showing the binding and warp threads in position while weaving the bottom piece. Fig. 2 is a front view of the i same. Fig. 3 is aside elevation similar to Fig.
1, except that the binding and warp threads are shown in position while weaving the top piece, and Fig. 4 is a front view of the same. Fig. 5 is a side elevation of the lower part of the mechanism, showing the way in which a sidewise .movemeut is given to the selvagewarps from a cam driven from the low shalt. Fig. 7 is a side elevation, and Fig. 8 a front view, of the selvage-forming mechanism for a two-shuttle loom.
It will be seen that in Figs. 1, 3, and 7 part of the frame-work is cut away in order to show the position of the needles more clearly.
Diagram A shows a perspeetiveviewof a sh ort length of a double pile fabric woven face to face, with fast inner selvages-down the center of the upper and lower cloths of the fabric. Diagram B shows a perspective view of one-half of this fabric when the pile has been severed and the upper cloth separated from the lower cloth. Diagram 0 shows two separate pieces obtained by dividing the fabric-shown at Diagram B longitudinally between the fast selvages which are formed in it. In these diagrams, A is the upper cloth, B the lower cloth, and O the pile. The two parallel lines D D, which run lengthwise of each cloth, represent the fast edges of inner selvages.
In Figs. 1 to 6, A A are selvage-warps, which are drawn from a reel or bobbin, B;- but they might, if desired, be taken from the same beam as that upon which the other selvagewarps are carried, or from the main warpbeam.
0 O are the binding-threads, which are drawn from a reel or bobbin, D. p
The warps A A are threaded through the thread-eyes J J J J to which a sidewise shogging movement is imparted. The .binding-threads C0 are threaded through the eyes of the needles F G G, to which an upand-down movement is imparted. The bindingthreads O, for the upper pair of needles, are led downwar.d to the eyes of the needles through eyes in the bar F, to which the stems of the upper needles are secured. The bindingthreads for the lower pair of needles are passed under the guide-rods O. A' uniform tension ismaintained upon the bindingthreads O C during the alternation of shed by means of 'a cord, which carries weights d d (P. As the bobbin empties itself the cord is wound up and the weights raised until they pass over the top of the pulley and overbalance. They then drop down on the opposite side of the pulley and again tighten the binding-threads, and so on continuously.
E is a bracket or base, which is bolted to a cross-bar of the frame-work of the loom. E E" E are upright rods fixed into it. Upon the top of the rods E E is fixed a plate, E. Two guard-plates, E rise up from the top of the front' end of this plate. The needles F F G G and thread-eyes JJJ"J are between these two plates, which keep the other warps from interfering with their action. To the top of the guard-plates E is secured another plate, E the plates EE, as shown in Figs. 1 and 3, and is secured to both these plates.
,Fis a bar to which theupper needles, F F, are secured. G is a similar bar, to which the lower needles are secured.
H is a connecting-rod, which passes through vertical holes in the plates E E. and connects the bars F and G together. This connectingrod receives an up-and-down motion from one of the heald-levers. H is a union for coupling the eonnecting-rod H to a rod, H, which passes downward from the lever. The upper pair of needles, F F, pass through holes in the guide-plate E, whereby they are guided in their up-and-down motion. The lower pair of needles, E E similarly pass through holes in the guide-plate E. The bar G, to which the lower needles are secured, is guided-in its up-and-down movement by the rods E E The bar F, to which theupper needles are secured, is guided in its up-and-down motion by the rod E" and also by another rod, K, which passes through it.
J J J J are guide-fingers having eyes at their extremities, through which the warpthreads A A are threaded. These guidefingers extend from a collar, I, which is fixed upon the rod K. A rocking motion is im- The rod E is prolonged upward through I parted to the rod K, so as to give a sidewise toand-fro movement to the guide-fingers. To effect this the rod K, at its lower end, is made to pass through the base-plate E, and a collar toward a tappet or cam, N, so that a pin which descends from the end of the lever'arm rests always against the surface of this tappet or cam. The tappet or cam N is carried by a short upright shaft, L, which, by a worm, L, and worm-wheel L is driven from the ordinary low or picking shaft, L, of the loom. The upright shaft L is mounted in hearings in a bracket, M, which is attached to the framework of the loom.
The operation is as follows: \Vhen the parts are in the position shown in Fig. 1, three picks of weft are put into the bottom cloth, and the threadeyes are during this time shogged sidewise a distance equal to the distance between the needles of each pair. Afterward the needles descend and three picks of weft are put into the upper cloth. After this the needles rise and three picks of weft are put into the bottom cloth, and during this time the' thread-eyes are shogged back into their former position, and so on continuously. 'I'n-this way the fast selvage edges are formed in each r to the loom described in the specification of a former British patent granted to George Davies, No. 2,429, in the year 1858, so thatit will be unnecessary to give any description of it. The parts of the loom are only shown in order that the way in which the fast-selvage mechanism is to be applied to it may be clearly seen.
In the mechanism shown at Figs. 7 and 8 for a two-shuttle loom the same parts are marked with the same letters of reference as.
in the preceding figures. The mechanism necessarily differs somewhat from that above described, because when two shuttles are thrown simultaneously it is necessary to open twosheds for the shuttles to be passed through. To do this we not only give an up-and-down movement to the needles, as in the mechanism just described, but also give an up-and-down motion'to the bar K, such up-anddown movement being in an opposite direction to that of the connecting-rod Hthat is, that when the rocking bar K is being drawn down the connecting-rod H is drawn up. The rod H is raised and lowered by being connectedat its upper end to one of the heald-levers, as in the mechanism shown at Figs. 1, 2, 3, and-4, and the bar Kis connected to another of the healdlevers, that goes up when the heald-lever to again caused to reverse their positionnp and down, and lateral movement is again given to the thread-eyes, and so on continuously.
In order that the'lever 0 may always remain bearing against the cam on tappet N, notwithstanding that the bar K is moved upward and downward, the pin which is carried at the end of the lever, and which rests against the cam or tappet, is made longer than the length of upward and downward movement given to the bar K.
Having thus described the nature of our said invention and the manner of performing the same, we would state that we are aware that mechanism has before been employed for forming fast inner selvages in cloths or fabrics which are being woven singly in power-looms. Our invention does not in any way apply to the weaving of single cloths with fast inner selvages, but relates only to double pile fabrics woven face to face. i
What we claim is- A double pile fabric woven face to face and with fast inner selvages both in the upper and lower cloths of the fabric, and with the fast selvages in the upper cloth of the fabric formed immediately above the fast selvages in the lower cloth, substantially as hereinbefore described.
