12 Claims. (Cl. 139-"188') This invention is an improvement in or modification of the invention described and claimed in my prior application No. 3,847, filed January 28th, 1935.

My invention comprises the improvement in or modification of the invention of said prior application according to which the, shuttle in its flight through the warp shed is supported entirely independently of the reed, if such is employed.

My invention furthercomprises supporting the shuttle in its flight through the warp shed by depending arms or fingers which extend to the opposite sides of the shuttle and ,form a race therefor. Y

My invention further comprises the arrangement in which there is no reed between the shuttle when in flight through the warp shed, and the healds.

Referring to the accompanying explanatory drawingss- ,7

Figurelhis a diagrammatic view showing a loom with shuttle supporting means arranged in one convenient form in accordance with the present invention.

Figure 2 shows means for giving a sideways movement to the reed of the Figure 1 construction of loom.

Figure 3 is a side view' of the reed.

Figure 4 is a view similar to Figure 1 but showing a m construction without a reed.

In Figure 1, a indicates the reed, b, c the healds, d the beat-up comb, e the shuttle, and f the warp threads.

The shuttle e when in flight through the warp shed is supported between depending arms or fingers g, h which provide between them a shuttle race. The armsor fingers g have their operative faces shaped to provide a track for a ridge or rib i on the shuttle whilst the fingers it have each a projecting part hl which comes beneath the rear edge of the shuttle.

The arms or fingers g, h are supported by a cross rail 7 and spaced to allow the warp threads to pass between them.

The beat-up comb d enters the warp threads when the shed is closed and all the warp threads are in line as in the prior application before referred to. The mechanism for actuating the comb may also be as described in the said prior application.

The reed a may be arranged for sideways reciprocation across the loom as shown in Figure 2 by means of the excentric a as in the prior application before referred to, for the purpose of grouping the warp threads differently in the teeth at of the beat-up comb at each beat-up-with the object of producing a good even finished clot-h. In the-example illustrated, threads 2: and u may be between two teeth of the comb at one beating-up operation and threadsy anda be together at the next beating-up operation The grouping will however, depend upon the number of threads in the reed, the spacing of the teeth of the beating-up comb and the extent of the sideways movement of the reed.

The reed generally has two threads per dent for coarse yarn, but if the reed arrangement shown in Figures 2 and 3 be employed, one thread may be in each dent. v v reed consists of two parts with their teeth staggered with relation to one another, that is one part of the reed containshalf the number of teeth and the other part, the other half of the teeth. Ihe two parts diverge so that whilst all the threads: are correctly spaced when they are in line at the base of the reed, there is. room for the threads to cross freelywhigher up the reed.

in the arrangement shown in Figure '4, there is no reed and the beat-up comb it enters between the warp threads adjacent to the line of the heald eyes b, 0' when these have brought the warp threads into line by the lowering of the upper row of warp threads to the level of the lower row.

What I claim is:

1. A loom for weaving comprising a reed, a. shuttle track supported entirely independently of said reed, parallel thereto, and adapted to support a shuttle suspended therefrom, a beatup comb, and means to raise said beat-up comb to bring its teeth up into the shed in very close proximity to the dents of said reed, to move said comb forward below said shuttle track to the fell of the cloth, to lower it, and to return it below the level of the shed to a position in proximity to the reed.

2. A loom for weaving comprising a reed, a shuttle track supported from above entirely independently of said reed immediately in front thereof and parallel thereto, the said shuttle track being adapted tosupport a shuttle suspended therefrom, a beat-up comb and means to raise said beat-up comb to bring its teeth up into the shed in very close proximity to the dents of said reed and behind said shuttle track, to move said comb forward below said shuttle track to a position in front of said shuttle track, to lower it and to return it below the level of the shed to a position in proximity to the reed.

It will be seen that the 3. A loom as claimed in claim 1 in which the support for the shuttle track extends across the loom above the level of the shed, and in which there are downwardly extending fingers carried by said support which are so shaped as to be adapted to engage and support a shuttle while in flight through the shed.

4. A loom as claimed in claim 1 in which the shuttle track is constituted by a series of stationary fingers extending downwards into the shed and so shaped as to be adapted to pass to opposite sides of a shuttle while in flight through the shed and to engage the same one beneath the rear edge thereof and the. other at the front side thereof.

5. A loom as claimed in claim 2 in which the support for the shuttle track extends across the loom above the level of the shed, and in which there are downwardly extending fingers carried by said support which are so shaped as to be adapted to engage and support a shuttle while in flight through the shed.

6. A'loom' as claimed in claim 2 in which the shuttle track is constituted by a series of stationary fingers extending downwards into the shed and 'so shaped as to be adapted to pass to opposite sides of a shuttle while in fiight through the shed and to engage the same one beneath the rear edge thereof and the other at the front side thereof.

'7. A reedlessloom for weaving comprising healds, a shuttle track in front of and parallel to the line of said healds and adapted to support a shuttle suspended therefrom, a beat-up comb, and means to raise said beat-up comb to bring its teeth up into the shed behind said shuttle track in very close proximity to the line of eyes of said healds, to move said comb forward below said shuttle track to the fell of the cloth, to'lower it and to return it below the level of the shed to a position'in proximity to the reed.

8. A reedless loom for weaving comprising healds, a shuttle track supported from above immediately in front of and parallel to the line of said healds, the said shuttle track being adapted to support a shuttle suspended therefrom, a beatup comb, and means to raise said beat-up comb to bring its teeth up into the shed behind said shuttle track in very close proximity to the line of eyes of said healds and behind said shuttle track, to move said comb forward below said shuttle track to a position in front of said shuttle ,track, to lower it and to return it below the level of the shed to a position in proximity to the reed.

9. A loom as claimed in claim 7 in which the support for the shuttle track extends across the loom above the level of the shed, and in which i there are downwardly extending ingers carried by said support which are so shaped as to be adapted to engage and support a shuttle while in fiight through the shed.

10. A loom as claimed in claim 7 in which the shuttle track is constituted by a series of stationary fingers extending downwards into the shed and so shaped as to be adapted to pass to opposite sides of a shuttle while in flight through the shed and to engage the same one beneath the rear edge thereof and the other at the front side thereof.

11. A loom as claimed in claim 8 in which the support for the shuttle track extends across the loom above the level of the shed, and in which there are downwardly extending fingers carried by said support which are so shaped as to be adapted to engage and support a shuttle while in flight through the shed.

12. A loom as claimed in claim 8 in which the shuttle track is constituted by a series of stationary fingers extending downwards into the shed and so shaped as to be adapted to pass to opposite sides of a shuttle while in flight through the shed and to engage the same one beneath the rear edge thereof and the other at the front side thereof.
