HEDDLE-FRAME.

Specification of Letters Patent. Application filed November 29, 1912. Serial N 0.

To all whom 1' i may concern:

Be it known that. I, JACOB K UFMANN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphla and State of Pennsylvania, have invented certain new and useful Improvements 1n Heddle-Frames, of which the following is a specification.

My invention relates to heddle frames for looms and it has particular relation to the 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 but which, however, will permit the bars to be easily and conveniently mounted in and dismounted from the frame when desired.

In Letters Patent No. 952,563 granted to William F elir and myself, March 22, 1910, there is shown a form of heddle bar supporting means having certain structural advantages and permitting a free sidewise movement of the heddles on the heddle bars to the desired extent, but in the structure there shown the heddle bar was supported in a hooklike member which was open at one end to permit the insertion of the heddle bar. On account of being open in that manner, the heddle bars soon closed end of the hook due to the j arringresulting fro-m the reciprocation of the frames in the loom and the bars are thus permitted to become displaced sidewise thereby causing breakages through fouling with the ad- My present invention contemplates an improved form of the slidable supporting member shown in the above mentioned patent, which while permitting the bar to be more easily and conveniently inserted and removed, will also serve to limit the same. against undue movement and the consequent wear resulting from the reciprocation of the frame in the loom.

The nature and characteristic features of any present invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part hereof, in whichview of a hedthe frame embodying the main features of my present invention; Fig.

wear through the 2 is. a fragmenv V shown in Fig 2, the bars being shown in secshown" in Figs. 1, 2 and 3.

Referring to the drawings, the heddle frame there shown consists of the top and bottom bars 6, connected at their ends by means of the side straps 7. Extending from end to end of the heddle frame and arranged near the top and bottom in the usual manner are the heddle ba s 8 upon which the bed dles 9 are mounte Auxiliary supporting bars 10 are supporte from the top and bottom bars 6, said supporting bars 10 being preferably rectangular in cross section, for a purpose to be presently explained, and as set forth in the previous Letters Patent No. 952,563 hereinbefore referred to, and these bars 10 are preferably supported from the frame bars 6 in the manner described and shown in that patent.

Slidably mounted on the supporting bar 10 is the heddle bar supporting member 11 comprising the principal element of my pres- --ent 1nvention, and consisting of a plate 12 having an aperture 13 near one end of a shape to -permit the upon the bar 10, but

being incapable of rotation thereon. The

plate 12 is also provided with a recess 14 open at one side and of a width equal supporting bar 8.

Pivoted to the plate 12, as at 15, intermediate the aperture 13 and recess 14, is a closure plate 16 which is provided with a recess 17 complemental to the recess 14 of plate 12 but opening on the side opposite thereto,' the recesses 14 and to the width' of the heddle the closure plate '16 is likewise provided with a complemental crease 19 to provide Patented Mar. 24, 1914.

plate 12 to freely slide for'means for maintaining the plate 16 in the closed position and preventing the same from becoming accidentally opened during the reciprocation of the heddle frames in the loom, yet permitting the same to be arbitrarily opened when it is desired to insert or remove the heddle bar.

It will thus be seen that there is provided a simple and eificient means for supporting the heddle bars intermediate their ends which will not interfere with the requisite sidewise movement of the heddles on their bars (the supporting member 11 being freely slidable with respect to both bars) but which will prevent undue lateral movement of the heddle bars and consequent rapid wear of the supporting member 11, and which will also permit the heddle bars to be easily and conveniently removed and inserted when desired. It will. also be seen that the supporting member being mounted upon the auxiliary supporting rods of rectangular or other non-circularoutline, there will-be no tendency for the supporting member to permit the heddle bar to move out of its proper plane durin the reciprocation of the heddle frames in t e loom.

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

1. In a heddle frame, the combination of the auxiliary supporting bar of non-circular cross-section, a lnemberslidably mounted on said bar having an aperture of complemen- :15

tal shape to prevent rotation with respect thereto, said member having a recess open on its side, a heddle bar mounted in said recess of a width corresponding to the width of said recess, and means for closing the open side of said recess, said means comprising a plate pivoted to said member betweenthe recess and the aperture, and means for maintaining said plate in closed position.

2. In a heddle frame, the combination of the auxiliary supporting bar of non-circular cross-section, a member slidably mounted on said bar having an aperture of complemental shape to prevent rotation with respect thereto, said member having a recess open on its side, a heddle bar mounted in said recess of a width corresponding to the width of said recess, and means for closing the open side of said recess, said means comprising a plate pivoted to said member be- I tween the recess and the aperture, and means for maintaining said plate in closed position comprising complemental creases in the member and plate.

In testimony whereof, I have hereunto signed my name in the presence of two witnesses.

JACOB KAUFMANN.
