H. EPSTEIN HAND WEAVING DEVICE sept. 4,' 1951 Filed Jan. 23, 1947 INvr-:NroR HERMAN EPSTEN ATTORNEY Patented Sept. 4, 1**951 UNITED STATES PATENT oFFicE HAND WEAVING DEVICE Herman Epstein, Newark, N. J. Application January 23, 1947, Serial No. 723,769

6 Claims. 1

This invention relates to new and useful improvements in hand weaving implements.

This invention is an improvement of my co. pending application, Serial No. 653,753, filed March 12, 1946, now Patent No. 2,463,365, in which I disclosed a weaving implement comprising a board having upright guides and a hand-.operated tool to depress certain lengths of the yarn lying within thelguides to permit the passing of a needle therethrough and thus eifect weaving.

In accordance with the present invention, the number of guides is reduced about onehalf, resulting in weight and cost reduction and facilitating operation of the yarn-depressing tool.

According to another feature of the invention, the yarn-depressing tool is arranged to depress at least one complete row of yarn at a time without employing both hands of the weaver.

Another feature of my invention provides for the correct alignment of the yarn-depressing tool with the rows of guides, without requiring particular eifort from the weaver.

The invention will be more fully explained in the following detailed description, the appended claims, and the drawing, in which:

Fig. 1 is a perspective view of the weaving board and the yarn-.depressing tool on it;

Fig. 2 is a plan View of some of the guides;

Fig. 3 is a side view of the cross-piece in nonoperating position on the board;

Fig. 4 is a front view of the cross-piece in operative position with the needle inserted; and

Fig. 5 is a cross section of a spring-loaded plunger.

Rectangularly shaped base I of the weaving board rests on suitable supports 2 at its four corners. A plurality of upright guides or pins 3 project from the base in a square and are arranged in rows which cover substantially the entire surface of the base. The construction and arrangement of guides 3 have been described in my copending application and the present guides are similar to those there described except that the number of guides is reduced.

The reduction in guides is accomplished by eliminating about one-half the guides heretofore used in the inside rows. The guides in the inside rows are staggered in adjacent rows. However, the number of guides in the marginal rows has not been reduced and, as in my copending application, the guides in opposite marginal rows of the square correspond. For instance, each guide in marginal row A (Fig. 2) is aligned with a guide in the marginal row (not shown) on the opposite side of the square. I f row A were completed, there would be thirty-two guides in it, as well as in the opposite marginal row. 1nside rows, such as B and C, if completed, would each have seventeen guides but, as shown in Fig. 2, the guides in adjacent rows (B and C) are staggered with respect to one another. Each inside row has one guide for each second guide in the marginal rows.

Yarn-depressing tool 4 is a bridgelike structure arranged to engage slidably base I and pass over guides 3. Tool 4 comprises a yoke 5 having pedestals 6 and I mounted on feet 8 and 9. Each foot has a slot or groove adapted to engage polished edges IIJ and II of base I. Movable cross-piece I2 extends between pedestals 6 and 1 and may be moved perpendicularly to base I. Leaf spring I3 is attached near its middle to yoke 5 and at either end to cross-piece I2 by suitable means, such as screws I4 and I5. Cam I6 is fastened near the center of yoke 5 by shaft II and rests on top surface I8 of crosspiece I2?. Projections (not shown) at either end of cross-piece I2 fit into slots I9 and 20 of pedestals 6 and 'I so as to guide the crosspiece when it is moved. Prongs or projections 2I extend from the bottom surface of cross-piece I2 and are spaced so that they may engage the warp lengths of yarn crossing two rows of guides 3. The prongs 2| are moved down to engage the yarn by rotating lever 22 of cam I6 clockwise. Cam I6 forces cross-piece I'2 down and flexes spring I3 until lever 22 is returned to the posi tion shown in Fig. 1. Spring I3 then springsl back to normal and carries cross-piece I2 up and free of guides 3.

Although in the preferred embodiment of my invention I have shown projections 2I adapted to mesh with four rows of guides 3v at a time, it is to be understood that tool 4 may be constructed to have projections which mesh with more or less than four rows of guides 3.

Each projection 2i has tines 23 and cut-away portions 24. When the tool is in non-operative vposition on the board (Fig. 3) tines 23 clear guides 3 so that tool 4 may be moved along the board on feet 8 and 9. When lever 2'2 is rotated, projections 2I are depressed and mesh with guides 3 (Fig. 4). A needle 25 carrying the weaving lengths of yarn is inserted in one end of tool 4 and pulled through to the other end. This procedure is repeated in the adjoining row of guides. After two rows are woven the cross-piece is raised into non-operative position, the tool moved along to the next depressions 29 (Fig. 1) and two more rows woven. This procedure is repeated until the fabric is completely woven.

Spring-pressed plungers 26 and 21 are mounted in feet 8 and 9 so that points 28 (Fig. 5) register with depressions 29 along opposite edges of base l. Depressions 29 are spaced between the suitable rows of guides 3 so that when plungers 26 and 2'! register with the depressions, tool 4 will be in position to permit projections 2| to mesh with guides y3. When plungers 26 and 21 are pulled out to the position shown in dotted lines (Fig. 5), points 28 are withdrawn from depressions 29 and tool 4 may be moved along surfaces lll and Il.

The laying and weaving of lengths of yarn between guides 3 are performed in the same manner as described in my copending application. Warp lengths 3B (Fig. 2) are laid across the square between adjacent warpwise rows, such as D and E. Next, weft lengths 3| are laid across the square between alternate transverse; rows, suchas F and G. Then, second warp lengths 32 are laid across the square in rows, such as H and I, skipped by lengths 3G. Finally, second Yweft lengths 33 are Woven across the square by needle 25 in rows, such as J and K. Projectionszl engagne only lengths 32 in rows J and K and depress them below the level of top surfaces 35 of base portions 34 (Fig. l) of guides 3. When needle 25 passes lengths 33 along top surfaces 35 in rows J and K, lengths 33 are alternately placed lunder lengths 3B and over lengths 32 (Fig. 2).

The marginal guides provide a continuous enclosure so that each inside row in the square has a guide at either end around which the warp and weft lengths 39-33 may be looped, thereby permitting a fabric to beA woven from one continuous4 length of yarn. However, the guides of the inside rows are not continuous but staggered because Iv have found that the warp and weft lengths may be held in position satisfactorilyl by alternate guides. The reduction in guides not only lowers the manufacturing cost of the device but speeds up its operation.

What is claimed is:

1. In a hand weaving device, a base, a plurality of evenly spaced yguides arranged on the base in rows covering substantially the entire surface of the base for supporting lengths of yarn, the marginal guides of said plurality of guides adapted to have lengths of yarn fastened thereto, the number of guides in a marginal row being greater than the number of guides in any one inside row, and a lever operatedvtool having projections adapted to mesh Ywith certain rows of guides.
