HiQDDLE- FRAME.

Specification of Letters Patent.

Patented Feb. 23, 1915..

Application f led July 23, 131 Serial No.

To all whom it may concern I Be known that LJOnN WAL ER, J12, a citizen bf theUnited States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Heddle Frames, of lwhich'the following is a specification.

One objectof my invention is to produce a durable and inenpensi've'hddle frame for .lqgims in which the ,heddles may be freely ifi ived in order that the weaver can easily get hold'of the portions of the ,warp'threads back of the heddleframe or when for any other reason it isldesiijed'to move the heddles or change their positionin the frame.

. Another object of'the invention is ,to so construct the device that the means which peifinit the movement of the heddles shall not inter fere-"with the necessary free movement of the heddle frames during their alternate rising falling 'movement under opera-ting conditions.

i A still further obj ect of the invention is to prevent one heddlefra'me from injuring another during the operation in the loom.

'lfhes eobjects aridother advantageous ends I attain as hereinafter set forth reference bein'gh ad tothe accqmpanying drawing in which,

Figure 1 is an elevation of a heddle frame showing inventio n applied thereto;

Qis an enlarged elei at'io'n, partly in secitipnnfurther illustrating 'my invention; Fig. 3 is aninverted plan of the parts shown in Fig. 2; the heddle bar being omitted for ,clearnes s'; and Fig. 4 is .a section on the line dj'a, Fig. 2; I x j Referring to the above drawings ',the frame consists of two parallel b eams l and 2 preferably made of vvood and secured togetherat their ends by two metallic tie memhere 3 and 4 each having holesattheir upper and lower portions through which the ends of two parallel heddle supporting :bars 5 and 6 extend. These bars in the present instance have-holes at their outer ends for the reception of spring wire clamps 7 designed toppevent their longitudinal movement.

As a means for supporting the heddle bars 5 and 6 at points within the frame I provide a number of similar devicesshown in detail in Figs. 2, 3 and 4, and for their reception the frame beam 1 is recessed at 8 to receive a fiat metal strip 9 which has its outer face flush with the inner edge 10 of the said beam. Slidably mounted on the outer flat surface thereon.

of the strip 9 is a Hat sliding metal plate 11 slotted at'12 and 13 and having riveted or otherwise secured to it a depending hook 15 placed at a point between said slots. This hook has an opening 16 shap d to receive the edd e .si pro ti b 5 (F gs 2 (and Q)- The slidahle plate 11' is movably attached to thestr'ip '9 by screws 17 and 1 8 which respect vely pass through the'slots l and 13 and 'enter holes in said strip. The parts are so arranged and proportioned that when the hook 151s in its normal position the screws .will be substantially in the middle of the slots 12 and 13, as shown in full lines in Figs/2 is 3, n the friction b tweh the slidable plate 11 and the strip 9 may helreg ulated by tightening or loosening thesescrews.

The heddles may be of any suitable construction and are suspended betv veen the supporting'barso and 6 in the usual manner s th t h y m y be d ongi udina y When in use, those heddles which are adacent the hooks 15 of the several'supp'orting devices may be conveniently separated by the weaver, since it is merely necessary to push them along the supportingrods 5 and 6 unt l their pressure against said'hooks is suflicient to move the latter and thereby form an opening through which the weaver may insert his to repair or tie any ends of warp whichhave broken during theweaving v ,1?. iatflon. In Fig. 2 the hook is shown in we positionso'f which the normal or central is shown in full lines-while the broken lines illustrate said hook in a positionfi'nto which it may be moved.

It'willbe noted (Fig. 3 that by having 7 the contacting faces of the slidable plate 11 and'the metallic strip 9 flat the hook 15 cannot rock or otherwise move beyond the planes of the side surfaces of the frame beams l and 2. This is a very important and valuable feature of my invention, since' heddle frames oftenhave to ,beplaoed very close together and if'a portion of one frame fly fibers which are present during weaving, for it will be observed that the strip 9 is set flush within the recess of the beam 1 so that any fly fibers settling thereon are either brushed off by the movement of the slidable plate 11 or can be easily removed. As before stated, different degrees of friction may be caused between the strip 9 and slidable plate 11 by means of the screws 17 and 18 and in some cases the friction may be made so intense that a number of the heddles may be bunched between the upper and lower hooks; thereby crowding or bunching the warp to produce rib weaves.

In the drawings I have shown a frame having four heddle bar-supporting devices, two at the top and two at the bottom,.but it will be understood that any number may be employed without departing from my invention.

While I have described one of the supporting devices as secured to the bar 1, it will be understood that in securing it to the beam 2, the latter is. recessed to receive its strip in the same manner as indicated at 8 in connection with the beam 1, Fig. 2.

I claim 1. The combination in heddle mechanism of a frame; a heddle-supporting bar; a plate having a hook for holding said bar; and means for holding said plate in slidable engagement with said frame, the same being adjustable to vary the friction between the plate and frame.

2. The combination in heddle mechanism of a frame having a flat portion; a heddlesupporting bar; a flat plate slidable on said flat portion of the frame and having a hook extending therefrom for holding said bar; and means for holding said plate in sliding engagement with said flat portion.

The combination in a. heddle frame I having a heddle supporting bar of a slidable plate having slots therein; means extending through the slots for movably connecting the plate to the frame; and a hook on said plate placed to hold said heddle supporting bar.

1. The combination in a heddle frame of a member having a recess; a flat strip fitting said recess; a slidable plate having a fiat surface for engagement with said strip; a heddle supporting bar; a hook on said plate for holding the bar; and means for limiting the movement of said plate and for securing it to the recessed member.

5. The combination in a heddle frame of a member having a recess; a flat strip fitting said recess; a slotted slidable plate having a. flat surface for engagement with said strip; a heddle supporting bar; a hook on said slotted slidable plate for holdin the bar; with means extending through said slots and strip for securing the plate and strip to said recessed member and for limiting the amount of movement of said slidable plate.

6. The combination in a heddle frame of a beam having a recess; a flat plate fitting said recess; a slotted plate having a flat surface slidably engaging said strip; screws extending through the slots in said plate and into said beam; a heddle supporting bar; and a hook rigidly secured to said slidable plate for holding said bar.

7. The combination in a heddle frame of a beam having a recess; a flat plate fitting said recess; a. slotted plate having a flat surface slidably engaging with said strip; screws extending through the slots in the plate and into said beam; a heddle supporting bar; and a hook for holding said bar rigidly secured to said slidable plate and having a flat surface in contact with a flat surface on the slidable plate.

8. The combination, in a heddle frame having a heddle supporting bar, of a plate slidably mounted on the frame and having a hook for holding said bar; and adjustablemeans passing through the plate for varying the friction between it and the frame.

9. The combination in a heddle frame of a member having a recess; a fiat strip fitting said recess; aplate having a fiat surface slidably engaging said strip; a heddle supporting bar; a hook on said plate for hold ing the bar; and means for varying the friction between the flat strip and the slidable plate.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
