LOOM.

Specification of Letters Patent.

Patented Feb. 24, 1920.

Application filed.l November 22, 1919. Serial No. 340,056.

. which the following is aspecification.

This invention relates to looms and has for its primary object the provision of an apparatus of this character which is designed primarily for use in vocational schools,

` hospitals or the like or by beginners receiving instruction in the art of weaving, the structure being especially designed so that it can be readily handled by convalescents and conveniently transported from one place to another.

Another object of the invention is to provide a loom which will consist of a yarn beam and cloth beam, mounted upon a novel form of frame so that both beams can be manipulated from la common working position, the frame also including a reciprocating reed mounted upon the frame to clean the cloth beam and yarn beam and provided with means whereby the reed can be quickly adjusted .to change the position of the warp threads when it is desired to produce a shed between the threads.

Another object of the invention is to provide a loom consisting of a frame having a cloth beam and yarn beam and a reciprocating reed between said beams, the said reed mounted in a carrier frame which is adapted to actas a batten for driving the weft thread against the previously woven part of e texture with a uniform sharp blow an thereby produce a thread surface `having an even texture throughout.

With the above and other objects in view which will appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out in the claims.

`In the accompanying drawings, has been illustrated, a single and preferred form of the invention, it being, however, understood that no limitations are necessarily made to .the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

.ards 6 and 6 at one end an In the drawings t- Figure 1, is a perspective view of the loom,

` Fig. 2 is a plan view thereof.

In carryin use is made o? cludes parallel side bars 5--5, arallel vstandsimilar parallel standards 7`and 7 at the other end of the frame. Each set of said standards is connected at the base of the frame by a brace bar 8. The brace bars 8 and said parallel side bars 5-5 are arranged slightly above the lower ends of the standards 6 and 6', 7 andI 7, so as to provide a clearance space below the side bars and permit the frame to be uniformly secured to a working table or the like. At the end of the frame which receives the yarn beam the bar 8 may be secured to the table by a suitable clamp (not shown), whereby the frame may be permanently held in a working position.

The cloth beam 9 has a trunnion 10 at one end which is freely journaled in thestandard 6, At the other end of the beam is a trunnion 11 of circular formation, the same journaled in a bearing'v passage 12 in said standard 6 so that the cloth beam can be revolved. The said standard 6 is split on a vertical line 13 so that a slot 14 1s produced which enters the bearing opening 12. This provides clampin extensions 15-15 which may be brought 1n clamping engagement against the trunnion 11 by meansof a fastening -bolt 16 which passes through said extensions 15-15 at a point abovethe trunnion 11. From this construction it will be seen that the cloth beam can be tensioned to any desired extent and held in a relatively fixed position.

The yarn beam 17 has its trunnions 18 mounted in bearing passages in the standards 7 and 7. Beyond one of the standards, the beam is provided with-a collar 19 having an annular series of passa es 20 in which a keeper in or latch 21 is a apted to engage so as to hold the beam against rotation when tension is placed on the thread. Each of the beams is provided at its ends with lsuitable actuating handles 21.

Guide rods 22-22 extend longitudinally of the frame and are respectively connected the invention into practice, a supporting frame which inwith the standards 6 and 7 and 64 and 7 l frame. A relatively heavy frame 23 is between the parts so as to permit said frame 23 to slide. without any frictional contact between the parts. The side bars 24 and 25 are provided with brackets 28 which are apertured at 29 for the reception of the rods 22. This supports the frame 23 from the main frame and provides means whereby said fra-me 23 can be uniformly moved in a horizontal plane between the cloth beam and said yarn beam. The inner faces of the side bars 24 and 25 are grooved at 30. The undeil l face of the top `bar 27 is grooved at 31. Slidable in the grooves y3()l is a reed 32, the upper end of which is adapted to be accommodated in the groove 27 on one adjustment of th'e reed so that a large shed will be produced between the upper and lower sets of the warp threads. The opening defined by the bars 24 and 25 and 26 and 27 is propor.

tioned so that suicient space isl provided beneath thereed to permit of the formation between the warp of a large shed when the reed is moved downward.v If desired, the movement in a downward direction may be increased by forming the lower bar 26 with a reed receiving groove 33 similar to the groove 31 in the top bar 27.

The shed between the warp threads is produced by an actuator which consists of a cord or iexible connection 34, one terminal of which is connected with the upper end of the reed and freely passed through a guide aperture 34 in the top bar 27. The

Icord is then guided through an eyelet 36.

on the b ar 25 and its free terminal is provided with a knob 37 which may -be engaged under 'a stop lug 38-when it is desired to hold the reedat the limit of its upward movement to produce a shed between the warp threads.

From the construction described, it will be seen that the means 19, 20 and 21, for holding the yarn beam against movement, and vthe means 16 for holding the cloth beam are A.on the same side ofthe loom with the reed actuator, and that all of the `parts are therefore in convenient reach of the operator so that they can be individually' controlled as the occasion necessitates. The

weight of the frame 24 acts as a batten whenthe reed is moved in the direction of the cloth beam so thatfa sharp blow may be set up against the weft thread, driving the. l

same .against the previously woven' part of the texture so as to produce an even surface throughout.

What is claimed as new is 1. Al loom Comprising a main frame, a yarn beam, a cloth beam, means co-acting with each beam to hold'the same against rotation, guidel rods carrled by the-main frame', a heddle frame slidable on the rodsbetween said beams, a heddle carried by said heddle frame, and means for adjusting the heddle in the frame to produce a shed between the warp threads.

2. A' loom comprising a main frame, a yarn beam, a cloth beam, means 3o-acting with each beam to hold the same against rotation, guide rods carried by the main frame, a heddle frame slidable on the rods between said beams, a heddle carried by said heddle frame, means for adjusting the heddle in the frame to produce a shed between the warp threads, said adjusting means comprising -a retaining device carried by the heddle frame, a flexible connector carried by the heddle, and means on said connection to 'engage with the retaining device to hold the heddle in its adjusted position.

In testimony whereof Iy have aHiXed my signature.
