Nov; 4, 1930 J. KAUFMANN HEDDLE FRAME Filed Nov. 16, 1928 Ja/M Patented Nov. 4, 1930 .UNI-TED STATES PATENT OFFICE JOHN JACOB KAUFMANN, OF ELKINS PARK, PENNSYLVANIA, ASSIGNOIB.l TO STEEL EEDDLE MANUFACTURING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A COR- PORATION 0F PENNSYLVANIA HEDDLE FRAME Application mea November ie, 192s. serial No. 319,778.

My invention relates to heddle frames for looms, and it relates more particularly to that type of heddle frame in which individual warp controlling heddles are mounted on supporting bars carried by the frame.

The principal object of my present invention is to provide a heddle frame which will be simple and inexpensive to manufacture, yet quite durable, and whichwill be relatively light yet substantially rigid.

The nature and characteristic features of m stdod fromthe following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is a side elevation of a heddle frame embodying the main features of my present invention;

Fig. 2 is a fragmentary detail view enlarged, partly in section, of a corner portion of the heddle frame shown in Fig. 1, the same illustrating more clearly the construction and arrangement ofthe same;

Fig. 3 is an end elevation of the portion of the structure shown in Fig'. 2; and

` Fig. 4 is a vertical section, taken approximately on the lin-e 4 4 of -Fig. 2. i

Referring to the drawings, in the particular embodiment of my invention therein shown, the heddle frame comprises top .and bottom rails '5, connected at their ends lby end members 6.

Each of the end members 6 comprises two i separate lstrips 7 and 8, made ofat metal.

The outer strips 7 extend over the ends of the top and 4bottom rails 5, and arebent over on the outer sides thereof, as at 9, being secured thereto by screwsy 10. 4

The inner strips 8 likewise have their end portions bent as at 11, extending along the innerl sides of the top and bottom rails 5, and being secured thereto by screws 12.

The strips 7 andv 8 of each endmember 6 are permanently secured to each other, pref- 'erably by means of spot welding at various points '13 along the length thereof, wherelby relative movement between the strips 7 `and 8 will be eliminated, andthe entire structure thus rendered 'quite rigid."

he heddle supporting bars 14, upon which invention will be more readily under-V the heddl'es 15 are mounted, extend through slots 16 in the end members 6, and the portions of the heddle supporting bars 14 which project beyond the outer faces of the end f members 6 17. g

Each of the apertures 17 in the ends of the heddle supporting bars maybe engaged by a hook-like extension 18 provided. at the free end of aJ retaining device 19, which is preferare preferably'apertured as ai ably made of spring steel wiref vf'lhe loweri end of the device 19 extends through an aperture 2O in the outer strip 7 ofthe end member 6, then passing as at 21 within a slot 22 inthe inner strip 8, again extending. outwardly through an aperture 23 in the outer strip 7, and being bent over -as at 24.

It will be noted that the portion 2l of the member 19 is located entirely within the slot 22 of the strip 8, so that no obstruction occurs onrthe inner face of the end member which might cause the warp to foul during the re'- .r

ciprocation of the framesv in the loom.

relatively inexpensive to manufacture, light in weight, and at the same .time will be quite rigid and durable.

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

A heddle frame comprising top and bottom rails, end members each comprising two ,separate flat metallic stripspermanently united to each other at a plurality of points, one of said strips having its end portions extending across the ends of the top and bottom rails and bentover-and secured on the outer sides thereof, the other of said strips having its end portions bent over and secured to the top and bottom rails along the inner sides thereof, heddle supportingl bars extending through registered slots in the end members, and retaining devices comprising spring wire hook members each having its freeend engaging one end ofxa heddle supporting bar and having its other end extending through apertures 1n the outer strip of each end'mem- 2 1,7so,`7se

ber, the portion thereof which is located on the inner side of said outer strip being positioned entirely within a slot in the inner strip of the end member.

In testimony whereof,` I have hereunto signed. my name.

JOHN JACOB KAFMANN.
