3 Claims. (Cl. 28-15) The present invention relates to improvements 10a. A suitable spacing of the grooves or notches in looms, more particularly of small size suitin the warp-spacers has been found to be 22 to able for use in the preparation of head work, for the inch. example, in the production of belts, girdles, neck- At their lower edges, the central portions of the 5 laces, bags and the like. end pieces and 11 are cut away for a portion 5 In the construction of looms of small size parof the central part of each, as indicated at 1'7 and ticularly suitable for use in bead weaving, great 17a respectively.

These slots 18 are quite The construction of the present invention is free long relative to their width and are disposed with from disadvantages in such looms as hitherto their longer dimensions substantially parallel to constructed, being composed of few parts of t pp e es of e e pieces 10 and 11. 15 simple and inexpensive construction, being As pointed out hereinafter, the end piece 10 is readily assembled without the use of nails, bolts p vi ed wi h it ble p r op n n 19 f r or nuts and screws, and being extremely rigid he re p n f h warpa ld n nd when assembled for use. The invention will be t g t p s 9d.

The end pieces 10 and 11 are Slight concave Curve, a at a. each formed of plates of suitable material, such In assembling the device, the t ues O tenons as metal or preferably, of hard wood s h as 21 of the tie plate 12 are forced into the narrow 'maple.

The upper edges standing that the principal pieces are of exof the end pieces 10 and 11 at or in proximity to tremely Simple d easily ucted form. the warp-spacers or combs and on either side In the use of the loom, the warp-threads in may be ruled with any suitable graduations, as at any desired number are preferably knotted to- 55 gether at one end and the knotted end of the warp-threads is brought around the outside of one 01' the end plates, suitably head plate 11, then under the latter through the opening 17a on the lower side of the end plate and up from the lower side of the tie plate through the opening 23, being held there firmly by forcing a conical or tapering pin 26 through the opening 23, as shown in Fig. 1. The warp-threads are then drawn across-the space between the warp- spacers 13 and 14 on the end plates, being carefully spaced upon the warp-spacers, the warp-threads extending between the two end plates being indicated at 28. At the opposite end, after passing over the warp-spacer 13 on the end plate 10, the warp-threads are separated in groups and each group is secured to a slotted, tapering tightening pin 19a forced into the tapered openings 19 in the .end plate 10. The taper of the openings 19 conforms to that of pins 19a, so that a substantial bearing and wedging surface is secured. By rotating these tightening pins, the warpthreads 28 or any part thereof may be stretched to the desired tightness between the end plates. In stretching the warp-threads in this manner, the center bar or tie plate 12 is somewhat bowed, and its resilience tends to maintain the warpthreads under the desired tension.

The construction as herein described and illustrated is composed of few and very simple parts, all of inexpensive construction and is readily assembled and disassembled without the use of nuts, bolts, screws, nails or the like. Furthermore, by reason of the method of assembly employed, the entire device when assembled is of very rigid stable construction and may hence be employed for the production of bead-fabrics of very considerable widths, say up to '7 to 12 inches. The structure, in use, provides a clear space between the warp-spacers for necessary manipulation by the weaver and the entire device is free from obstructions and from projections or parts of a character tending to catch the threads or otherwise interfere in weaving.

I claim:

1. A bead loom of readily demountable construction capable of being assembled to form a rigid construction comprising end plates having warp-spacers upon their upper edges and being provided with rectangular openings, and a tie plate extending therebetween, said tie plate having at each end a projecting tenon adapted to enter and pass through the opening in the corresponding end plate and spaced bearingshoulders on opposite sides of said tenon, and wedge means for forcing the end plates firmly against the bearing shoulders upon the tie plate whereby the end plates and tie plate are held in rigidly assembled relation.

2. A bead loom of readily demountable construction capable of being assembled rigidly and comprising end plates having warp-spacers upon their upper edges and being provided with rectangular openings, a tie plate extending therebetween, said tie plate having at each end a projecting tenon adapted to enter and pass through the opening in the corresponding end plate and spaced bearing shoulders on opposite sides of said tenon, wedge means for forcing the end plates firmly against the bearing shoulders upon the tie plate, whereby the end plates and the tie plate are held in rigidly assembled relation, an opening being provided in the tie plate between the end plates and near one of the latter, a. tapered pin entering said opening for retaining ends of warp-threads therein, the opposite end plate being provided with a. plurality of openings, and tapered pins adapted to enter the last-mentioned openings for receiving the corresponding ends of warp-threads and tightening the latter.

3. A bead loom of readily demountable construction capable of being assembled to form a rigid construction comprising end plates having warp-spacers upon their upper edges and being provided with rectangular openings, a tie plate extending therebetween, said tie plate being of fiat, somewhat flexible and resilient material and having opposite sides somewhat concave in curvature to increase the flexibility and resilience thereof, said tie plate having at each end a projecting tenon adapted to enter and pass through the opening in the corresponding end plate and also having spaced bearing shoulders on opposite sides of said tenon, wedge means for forcing the end plates firmly against the bearing shoulders upon the tie plate whereby the end plates and tie plate are held in rigidly assembled relation, and means for placing under tension warp-threads extending between said warp-spacers, thereby somewhat bowing the tie plate whereby tension is maintained on the warp-threads.
