ROGER 1\T. REYNOLDS AND THOMAS F. DOUGHERTY, OF ATLANTA, GEORGIA.

LOQM ATTACHMENT.

Application filed June 7, 1924. Serial No. 718,550.

To all wh'om it may concern:

Be it known that we, ROGER N. REYNOLDS and THOMAS F. DOUGHERTY, citizens of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Loom Attachments; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in loom attachments and more particularly relates to the harness and jack straps.

At the present time to raise and lower the harness the means provided is to run the end of the harness strap through a hook upon the harness and the end of the strap having a second hook attached to it fitted in holes in the other end portion of the strap. The holes are about an inch apart in the harness strap, so that only a rough adjustment is obtainable, and to get the fine adjustment the harness hook or rather the screw eye on the harness screwed in or out, but this ruins the threads in the' wood requiring that the screw eye be moved along the harness and in time considerably damaging the harness and also throwing the harness strap out of line with harness roller causing the harness to move in a sweeping motion laterally chafing the warp unnecessarily and at the same time causing a lateral strain on the harness strap where it is screwed to the harness roll as a consequence of which breakage prematurely oc- It is an object of the invention to do away with these prior' difficulties and to provide a strap adjusting device that will dispense with a great portion of the leather strap and with vthe holes in the same; also with the necessity for adjusting the screw eye or moving the same and the invention is well calculated to save both the straps and the harness.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more par ticularly pointed out in the claims appended hereto. I p

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views.

Figure 1 is a fragmentary front elevation of a loom showing the harness and the harness strap constructed according to the present invention.

Figure 2 is an enlarged sectional View through the harness strap and adjusting device.

Figure 3 is a perspective view of one portion of the adjusting clamp.

Figure 4 is a similar view of a comple-.

mental portion of the clamp.

Figure 6 isan edge View of the jack strap, with a portion of the clamp shown in section.

roll and 9 the portion of the frame work. The harness strap is indicated at 10 and'is fastened to the roll 8 as by the screw or other fastening 11, shown particularly in Figure 2.

The lower end of the strap 10 is adapted to slide through and between the two complemental portions of the clamp device and this strip is of short length as compared with the perforated straps now in use. The clamp consists of an outer sleeve 12 made of tapering form, or being larger at its upper end and tapering to a reduced lower end, the sleevebeing opened at its upper and lower ends and enclosed at its base and two sides with a slot 13 in its front wall to permit of the operation or swinging of the looking lever 14.. 1

The locking lever is preferably formed from rod metal bent intermediatel'y upon itself to provide double parallel portions 15 constituting a handle and the end portions are bent outwardly to form trunnions 16 adapted to rest and rotate in the notches 17 made in the tapering side walls 18 of the inner clamp member 19. The terminal ends of the lever are flattened on one side as shown at 20 in Figure 6 in order that when Referring more particularly to the drawings 7 designates the harness, 8 the harness the lever 14 is swungoutwardly to a position at right angles to the strap that the flat side 20 may be exposed to the flanges 21 on,

the front wall of the outer clamp member 12 and thus free the clamp member for longitudinal shifting movement with respect to the'companion clamp member 19. It will be-noted that the free edges of the walls .18 of the inner clamp member conform in point oftaper to the inclination given the flanges 21 of the outer member 12. The lever 14 may be lifted out of the notches 17 when the two clamp members are separated, but it is preferred to provide a spring having ends 22 for bearing against the terminal portions 16 of the lever to hold these-terminal portions within the notches 17 until positive pressure is produced to lift the trunnions out of the notches. The ends 22 of the' spring act to force the trunnions toward the base member 19 and the spring 23 itself is coiled about a rod 24 mounted in the perforations 25 of the walls 18, there being an intermediate portion 26 of the spring bent outwardly and rearwardly with respect to the ends 22.

As shown in Figure 2 this intermediate part 26 of the spring engages along the base plate 19 of the inner member whereby to prevent rotation of the spring upon the rod and to admit of placing of the spring in the proper potential condition for exerting resilient pressure upon the terminal ends 16 of the lever. The base plate 19 is extended into a bar 27 having a hook 28 at its lower end adapted to engage with a loop 29 upon a hook 30 which is engaged with the usual screw eye 31 fastened to the harness 7.

In the operation of the device the lever 15 may be swung. outwardly from the strap 20 through 90 degrees from the position shown in Figure 2 to thereby bring the flat side 20 opposite the inclined flanges 21 and the pressure will be released from the strap 10 which fits between the walls 12 and 19. The strap may be fed upwardly or downwardly or the bar 27 may be lifted or lowered with respect to the strap and a very fine adjustment had such as is not possible with the hook and tofore.

When the adjustment is efi'ected the two members are slidtogether with the inclined edges of the walls 18 slipping over the incllned flanges 21 thus causing the two walls 12 and 19 ,to approach one another upon the strap 10 and finally the lever 14 is swung upwardly to the position shown in Figure perforated strap as herewith little effort and no slippage can take place.

In the case of the jack strap shown in Figures 5 and 6, the use of the leather is done away with entirely and the same form of clamp is used. The screws in the harness do not have to be touched.

According to Figures 5 and 6 two companion- bars 32 and 33 are employed having mutually coacting inclined teeth 34 at their overlapped ends and provided at their upper and lower ends with hooks 35 and 36 respectively. p The overlapped ends are received in a clamp device snnilar to that described above and having parts similarly numbered except that instead of receiving the strap 10 the overlapped ends'of the bars 32 and 33 are received in the clamp device in the same manner and the inner clamp device is provided with a bar 37 extending parallel and in contact with the bar 33. The bar 37 is shorter than the bar 33 and is progided with a hook 38 above the hook 36, the hooks being provided for obvious purposes. I

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims What is claimed is 1. A harness strap for looms comprising a member adapted to connect/with the harness, an inner tapering clamp member associated therewith, an outer tapering clamp member sliding relatively to the first mentioned member, a strap received between the two members and clamped thereby, and cam means for. forcing the two members upon said strap.

2. In combination with the harness and harness ,roller of a loom, a strap attached to the roller, a bar attached removably to the harness, inner and outer tapering clamp members, one of said members being attached to said bar and said members adapted to receive the lower end of the strap therebetween, a lever having trunnions rotating in one member and adapted to bind against the other member, said trunnions having a flat side.

3. A harness strap for looms comprising a bar removably attached to the harness and strap, an inner clamp member having sides with tapering edges and notches, an outer clamp member having a slitted part with inclined flanges at the sides of the slit, said inclined flanges adapted to receive the ta ering edges of the walls of the inner mem er, a strap received between said members, a lever having trunnions loosely fitted in said notches, said trnnnions having fiat side faces, and a spring having arms engagingsaid trunnions to hold the same in said notches.

4. A harness strap for looms comprising complemental hooked bars having mutually engaging inclined teeth, a third hooked bar resting against one of the first mentioned bars, a clamp member associated with the last bar, a second clamp member extending about the toothed'portions of the bar and.

the first clamp member, and means for pressing the clamp members upon said toothed ends.
