HEDDLE FRAME.

Application led [January 12, 1924. Serial No. 685,752.

T6 all whom 1f/may concern.'

Be it known that I, JACOB KAUFMANN, a citizen of the United States, residing at Elkins Park, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Heddle Frames, of which the following is a specification.

My invention relates to heddle frames for looms, and it has particular relation to means for supporting the heddle bars intermediate their ends.

The principal object of my invention is to provide improved means for supporting the heddle bars intermediate their ends -Which will securely support said bars against undesirable motion and displacement, but which, however, will permit the bars to be quickly and conveniently mounted in and dismounted from the frame when desired.

My present invention contemplates an improved device for supporting the heddle bars intermediate their ends which, while permitting the bars to be moreeasily and conveniently inserted in and removed than heretofore, is so constructed and arranged as to reduce to a minimum the likelihood of the supporting device becoming disarranged while the heddle frame is in use and thereby fouling with the adjacent frames in the loom, thus vminimizing the possibility of damage which might be occasioned by such disarrangement.

The nature and characteristic features of my present invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure l is an elevational view of a heddle frame provided with heddle bar supporting devices embodying the main features of my present invention;

Fig. 2 is a fragmentary sectional view, enlarged, taken approximately on the line 2-2 of Fig. 1, the parts being shown in the normal positions assumed while supporting the heddle bar in the frame;

Fig. 3 is a similar view, but with the parts in the open position for the purpose of removing oi' mounting the heddle bar therein;

Fig. 4 is a fragmentary elevation enlarged, showing the novel form of supporting device mounted on`the heddle 4frame with the heddle supporting bar in operative relation thereto; and

5 is a perspective view of a slidable locking member, detached, comprising one of the elements of the device.

Referring to thc drawings, the heddle frame there shown consists of the top and bottom bars 6 connected at their ends by means of the side strips 7 Extending from end to end of theheddle frame, and arranged near the top and bottom bars 6 in the usual manner, are the heddle bars 8, upon which the heddles 9 are mounted.

The inner edge of each of the heddle frame bars 6 is preferably recessed, as at 10, wherever it is desired to support the heddle bars intermediate their ends. In this recess 10 is mounted the base portion 11 of abracket member constituting a part of the supporting device. The bracket member also has a portion 12 extending at right angles to the base portion 11, and consequently at right angles to the longitudinal extension of the heddle bar 8. In the extending portion 12 of the bracket member there is provided a recess 13 open at one side, as shown in Fig. 3 of the drawings, for the reception of the heddle bar 8.

A plate member 14 is slidably mounted on one side of the extension 12 of the bracket member. For the purpose ofv slidablv mounting said plate member 14, the same is providedwith a longitudinal slot 15 through which pass rivets 16, which 'are secured to the extension 12 of the bracket member, the rivets 16 having enlarged heads extending over the outer surface of the plate member 14, as clearly shown in Figs. 2 to 4 of the drawings. The plate member 14 is also provided with an opening 17 extending from the slot 15 to the marginal edge of the plate member 14 on the same side as that of the recess 13 of the extension 12 of the bracket member. The slot 15 is of such width as to permit the same to engage the heddle bar 8 when the slide member 14 is in the lowermost position, as illustrated in Figs. 2 and 4 of the drawings, the arrangement providing, in effect, an overlapping lip ortion 18 which serves to retain the hed le bar 8 within the recess 13 in the manner illustrated.

The upper end of the slidable plate member 14 is preferably provided with an extending lip or projection ,19, which is engage-d by the free end` 20 of a vJ-shaped leafl spring2'1, the other end 22 of which leaf spring is secured to the rail 6 of the heddle frame by being clamped beneath the base portion 11 of the bracket member, as shown in Fig. 4 of the drawings, it being understood that the base portion 11 of the bracket member is secured to said rail by means of screws 23 or other suitable fastening devices.

The operation of the device Will now be quite apparent. The supporting devices being rmounted in the heddle frame, as hereinbefore set forth, and it being desirable to mount a heddle supporting bar in the frame in such manner that the same Will be supported therein intermediate its ends, the heddle bar, With the heddles mounted thereon, is placed in the frame in the usual manner and its ends secured in lposition by means of Whatever type of fastening device Which may be preferred for use in connection therewith. The slidable member 14 is then manually pushed to the open position, 4as shown in Fig. 3 of the drawings. The central portion of the heddle bar 8 is now inserted in the recess 13 of the extension 12 of the bracket member, and thereafter the slide-ble member 14 is released and permitted to return to the normal locking position shown in Fig. 2 o-f the drawings, being impelled to this position by the tension of the leaf spring 21. The overhanging portion 18 will then serve to retain the central portion of the heddle bar 8 within the recess 13 and thereby securely hold the same against displacement during the operation of the loom. When it is desired to remove the heddle supporting bar from the supporting device, it will be necessary merely to again push and hold t-he slide member 14 in the position shown in Fig. 3 of the drawings, whereupon the heddle sup-porting bar 8 may be readily disengaged from the supportin device.

It will e seen that there is thus provided a simple yet'eiiicient means for supporting the heddle bars intermediate their ends which will prevent undue lateral movement of the heddle bars, and which is also so constructed and arranged as to preclude the parts of the supporting device itself becoming fouled. Possibility of the parts of the heddle frame, as Well as of the supporting device itself, fouling on adjacent frames, during thereciprocation of the frames in `the loom, will thereby be reduced to the minimum. l aving thus described the nature and characteristic features of my invention, what I claim as new and desire to secure by Letters Patent is:
