SPECIFICATION forming part of Letters Patent No, 330,109, dated November l0, 31.835.

Application tiled September 21, 18S5. Serial No. 177,694.

To all whom it may concern:

Be it known that I, SAMUEL N. GOODMAN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Molds for Casting,

of which the following is a specification.

The object of' my invention is to construct a mold for the convenient manufacture of an improved form of needle or nger bar for 1o knittingmachines, and this object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a perspective view of one form of the improved bar; Fig. 2, a side view of the mold for making the saine; Fig. 3, alongitudinal section ofthe mold; Fig. 4, a transverse section on the line l 2, Fig. 3, Fig. 5, a transverse section on the line 34, Fig. 3; Fig.

2o 6, a sectional plan on the line 5 6, Fig. 2; Fig.

7, a perspective View of a bar forming part of the mold, and Fig. 8 asectional View showing the mold adapted for the production 0f an ordinary needle-bar.

In making certain classes of knitted fabric it is desirable to produce a tufted or plush surface having loops or plush threads of differ ent lengths, and in a separate application iiled by me and bearing even date herewith I have 3o described and claimed a bar having needles or loop-retaining iingers in different longitudinal planes for use in making such a fabric.

My present invention consists of a mold for 3 5 Eianufacturing this improved needle or finger A is the baseof the mold, which has opposite sides or cheek-pieces .B B and a cap or cover plate, D, between which and the base 4o of the mold are coniined a series of bars, F, each of these bars being provided With a number of parallel notches, a, for the reception of the stems or shanks of the needles or lingers x. The bars F, with the body and the cap of the mold, inclose a space into which the buttends of the needles or fingers project, and which is filled with melted lead by pouring the latter through a suitable opening or gate in the mold. (See Fig. 2.) The bars F are 5o maintained in their proper lateral relation to each other by means of pins b and recesses d,

(No model.)

as shown in Figs. 4 and 7, cach recess being o pen at one end, for a purpose explained hereinafter.

A gage-cock,G, is guided between the cheekpieces B at the outer end of the mold, these cheek-pieces having slots f for the reception of the ends of the tapered piu g, which is adapted to an opening in the gage-block, so that by tightening a thumb-nut, L, upon the 6o projecting end of this pin the block G can be confined in the position to which it has been adjusted.

A stop-plate, II, is secured to one of the cheek-pieces ofthe mold by a pin, m, adapted to a slot, a, and this plate is also slotted for the reception of the pin g, and serves to limit the movement of the block G toward the bars F, and thereby prevent the projection of the butts of the needles or lingers inward to an 7o undue extent.

In setting up the mold the gage-block is first adjusted to the proper position, and the first of the bars Fis secured to the base of the mold, the needles or fingers which are to form the first row being then properly adjusted to the gage-block and to the notches oi" the bar F. The second bar is then laid over the first bar, and the second rows oi' needles or lingers applied thereto and to the gage-block in the 8O same manner, this operation being repeated until all the bars and all the iingers or needles are in place, when the cap-plate D is applied and secured by means of the clamp-screw J.

When the lead has been poured into the mold and cooled, the gage-block is retracted, the cover-plate removed, and the lead,with its needles or fingers, lifted ,out of the mold, a screw-stem, K, being used to eject it, if necessary. `The bars F are then withdrawn by. 9o removingthem, one after another, in the direction of the arrow, Fig. 3, from between the rows of needles or fingers, the open-ended recesses cl permitting this removal of the bars.

The mold can, if desired, be employed for casting a lead with a single row of needles or iingers or a lead having a less number of rows than is shown in Fig. l, the under side of the cap-plate in this ease being so formed as to prevent a large amount et' surplus metal in roo the lead. Thus, as shown in Fig. 8, the mold has one bar, F, and is adapted for the manufacture of a. lead having a single row of needles or fingers.

vI claim as my invention 1. The combination of the body of the mold, the cap-plate, and a. series of detachable bars, F, as specified.

2. The combination of the body of the mold, the cap-plate, and the detachable bars F, retained in position by pins and recesses, as specified.

3. The combination of the body of the mold, the cap plate, and the detachable bars F, notched for the reception of the needles or fingers, and having pins b and open ended recesses d, as set forth.

.Y 4..A v@net@mitm-tion 0f the body of the'moid,

the cap plateand the ,detachable bars F with a gage-block, G, as speciied.

5. The combination of the. body of the mold with thegageblock G, th'etapered pin g, and the thumb-nut h, as specified.

6. The combination of the body of the mold, the cap-plate, the detachable bars F, the adj ustable gige-blockQ its fpin g, and the stopplaite H, as specified.v p

In testimony whereofy I. have signed my name to this specification in the presence of two subscribing Witnesses. Y
