HEDDLE FRAME.

Application filed August 27, 1927. Serial No. 215,804.

My invention relates to heddle frames for V looms, and it relates more particularly to improved means, in a heddle frame of the usual type, for supporting the heddle bars intermediate their ends.

The principal object of my present invention is to provide improved means in a heddle frame, for supporting the heddle bars intermediate their ends, which will securely support said bars against undesirable motion or displacement, but which however will permit the same to be readily and expeditiously mounted in and dismounted from the frame when required.

A further object of my invention is to provide, in a heddle frame, a device of the slide hook type, for supporting theheddle barsintermediate their ends, which is soconstructed and arranged that the same may be readily adjusted in the'top and bottomv rails of the heddle frame whereby the heddle supporting bars willbe properly supported, and the heddles will not bind on the supporting bars, or on the other hand be permitted too great an up and down movement thereon.

A further object of my invention is to provide improved'means of the character aforesaid which is so constructed and arranged whereby the same may be readily disassembled and reassembled for the purpose of effecting the necessary adjustments, and which when assembled in the operative conditionwill be maintained with its parts in .the proper adjusted positions.

' The nature and characteristic features of my invention will be more readily understood from the following description taken in connection with the accompanying drawings forming a part hereof, in which I Figure 1 is an elevational view of a heddle frame having mounted therein devices embodying the main features of my invention; Fig. 2 is a vertical sectional view, taken on the line 2-2 of Fig. 1;

Fig. 3 is a. fragmentary elevational view, enlarged, of aportion of the heddle frame, il-

lustrating more particularly the improved means for supporting the heddle bars;

Fig. 4: is a transverse section thereof taken on the line 44 of Fig. 3; and

Figs. 5, 6, and 7 are perspective views of various component parts of the supporting device, detached.

Referring to the drawings in the particular embodiment of my invention therein shown, the heddle frame proper comprises top and bottom rails 10 connected at their ends by means of the side strips 11. Extending from end to end of the heddle frame, and arranged near the top and bottom rails 10 in the usual manner, are the heddle bars 12 upon which the heddles 13 are mounted.

erably of non-circular cross-section and having recesses 21 provided near their ends. The recesses 21 are adapted to engage the head portions of the bolts 15 beyond the slots 18 thereof. Itshould be noted that the slots 18 of the headportion of the bolts 15 are of such vertical length as to permit the body portion of the bar 20 to slide therethrough.

It should also be noted that the bolts 15 are so located in the rails 10 of the frame as to permit the several recesses of the bar 20 to simultaneously engage the head portions of the respective bolts 15.

A bowed leaf spring is mounted in the recess 14, being held therein by means of a wood screw 31. The free ends of the leaf spring 30 engage that edge of the bar 20 which is disposed toward the rail 10, and serve to maintain the bar 20 with the recesses thereof normally seated with respect to the head portions of the bolts 15.

Slidably mounted on the bar 20 is a hook member 40 having a slot 41 complemental to the cross-section of the bar 20. .The hook member is also provided in its free end with slots 42, open at one end. and adapted to receive and support the heddle bars 12.

In mounting the supporting device in the heddle frame the bolts 15 are first threaded into the holes 19 provided in the rails 10 for that purpose. When the bolts 15 are brought to the desired position with respect to the rail .10, and the leaf springflB'O may then be mounted thereon, after which the end of the bar 20 is slid through the slot 18 in the head ot his other bolt 15 until the recesses 21 oi the bar 20 are brought into register with bothbolt heads 17, where- 1 upon the ends of the leaf spring 80 hearing against the same will cause the recesses 21 of the bar 20 to be seated with respect to the heads 17 of the bolts 15, and in this manner the bar 20 will be locked against further longitudinal movement.

The heddle supporting bars 12 may now be brought into engagement with slots 12 of the hook member 10, it being understood that ordinarily it will be necessary to free i the ends of the heddle bars 12 from one of or bothof the side strips 11 to accomplish this purpose. 1

It will be seen that by reason of the hook member 10 being slidably mounted 011 the bar 20, the same will be free to move lengthwise of the frame, so that requisite freedom of the heddles 13 on the bars 12 will be permitted for the purpose or avoiding defects in the weave which sometimes occur when fixed hooks are used for supporting the heddle bars intermediate their ends.

It will also be seen that in the use out a device of the construction above described, it it should be found that the supporting device is causing the heddles to bind upon the supporting bars, or permitting the same to move too loosely thereon, adjustment may readily be made by dismounting the bars 20 from the heads 17 of the bolts then threading either or both of the bolts 15, in or out, in the holes 19 as re uired to effect the necessary adjustment. fter said adjustmentis made and the parts reassembled, the bolts 15 will be prevented from turning by reason of the bars 20 extending through the slots 18 in the heads 17 thereof. v

It will of course be understood that Various changes may be made in the arrangement without departing from. the spirit of my invention, as, for example, while the device as shown is applied to a heddleframe of the duplex type in which two sets of heddles are mounted in the frame on individual supporting bars, the hook members i0 may be provided with but a single slot 42, when the device is to be used in a heddle frame in which but one set of heddles is mounted.

Having thus described the nature and characteristie features of my invention, what I claim as new and desire to secure by Letters Patent, is:

1'. In a heddle porting the heddle bars intermediate their ends comprising bolts adjustably mounted in the top and bottomvrails otthe same, said bolts having slotted head portions, a bar adapted to pass through the slotted heads of the bolts, said bar having recesses adapted in the normal position 01. the bar to be seated with respect to the head portions oi the bolts, means adapted to hold said bar in its seated position with respect to the slotted ends 01"- the bolts and, a member mounted on the bar adapted to support the heddle bars.
