To all whom it may concern; 1

'Be it known that I, JAooB KAU MAN a citizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new and useful Improvements in Heddle-Frames, of which'the followingis a specification;

My invention relates to heddle frames and it has particular relation to improved means for strengthening or stiffening the top and bottom bars. of the frame intermediate the ends thereof. I

The object of my invention is to provide an improved form of stay or brace for the top and bottom rails of the frame which will effectually prevent springing of the frames and which will take the strain off the hed dles and their supporting rods therebv as suring freedom and easy play of the heddles on the rods at all times and preventing breakage of the same.

My invention also contemplates a form of stay which will. not interfere with move ment of the heddles on the rods in either direction and which is capable of a sufiicient sidewise adjustment as not to interfere with 7 changes in the patterns woven on the loom.

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 part hereof, in which- Figure 1 is an elevational view of a heddle frame provided with a stay or brace embodying the main features of my present invention; Fig. 2 is an enlarged fragmentary detail view, partly in elevation and partly in section, of a portion of the structure shown in Fig. 1, illustrating the manner of connecting the stay rod to the top and bottom bars of the frame; and Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2, the end portion of the stay rod being shown in side elevation.

Referring to the drawings, in the particular embodiment of my invention there shown, the heddle frame is of a common and well known type comprising top and bottom bars 4 usually made of wood and connected at their ends by metallic straps or bars 5. Mounted in and supported by the end bars 5 are the heddle supporting rods j Specification of Letters Patent. 7 Application filed September 10, 1915;. Serial No. 789,027.

6 upon which the heddles 7 are mounted in the usual or any desired manner. 1

At the places where it is desired to locate the'stay rods the inner portions of the top andbottombars are recessed, as at 8, the recessesbeing less deeply out near their ends to provlde seats 10 upon which rest the ears 11 at the ends of additional auxiliary bars 12 which are disposed within the recesses 8 and extend within said recesses in the same general direction as the top andbottom bars a distance suflicient for the required amount of sidewise adjustment of the stay rods to be provided for. The preferred manner of forming the additional auxiliary bars 12 is to take a bar' of substantially rectangular cross section and twist the end portions thereof .to form the ears 11 above referred to. The ears 11 of the bars 12 are prefer- V ably apertured for the fastening screws 13 which pass therethrough and are secured in the bars 4.

The stay rod proper comprises a bar 14: preferably substantially rectangular in cross section being twisted as at 15, near each heddle supporting rod so as to have the greater axis of its central portion extending trans verse to the frame to thereby offer as little obstruction as possible to the warp ends controlled by the heddles. The ends of the stay rod are bent over to form hooks 16 which engage the bars 12 as clearly shown in Figs. 7

2 and 3 of the drawings. The greater axis of the cross sectioniof the stay rod at its ends extends parallel to the longitudinal extension of the frame so as to provide a large bearing surface of the hook ends at their engagement of the bars 12 and also to offer little or no obstruction to the free sidewise movement or play of the heddles on their supporting bars 6 (see Fig. 3).

It will be seen that there is thus provided a simple and efficient form of stay or brace intermediate the ends of the heddle frame which has a sufficient range of adjustment sidewise so as not to interfere with the proper disposition of the heddles in the frame, which takes but a small space at the portion adjacent the warp ends, and which effectually insures freedom and easy play of the heddles on their supportng rods at all times thereby preventing straining and breakages of the heddles.

Having thus described the nature and characteristic features of my 1nvent1on,what I claim as new and desire to secure by Let- 'ters Patent is 1. In a heddle frame, the combination of the top and'bottoni bars, the heddle supporting rods, additional auxiliary bars secured to and extending in the same general direction as said top and bottom bars, and a'stay rod engaging said auxiliary bars andcapable of sidewise adjustment thereon, said 1 said recesses, and a stay rod engaging said auxiliary bars and capable of sidewise adustment thereon, said stay rod comprising a bar of rectangular cross'section having its ends bent over to form hooks for engaging said auxiliary bars.

In a heddle frame, the 'COIHblIltItlOD of the top and bottom bars, the heddle support-j ing rods, additional auxiliary bars secured to and extending in the same general direction as said top and bottom bars, and a stay Copies of this patent may be obtained for five cents each, by addressing" thevrCommissi'on er ofjlatezits,

rod comprising a bar of rectangular cross section having hooked ends engaging, said auxiliary bars; V V l. In a heddle frame a stay rod extendingsbetween the top and bottom bars, said stay rod being of rectangular crosssec'tion having the greater axis of its central por tion extending transverse to the frame and said recesses, a. stay rod ha inghookedends engaging said auxiliary bars, said stay rod being of rectangular "cross section having the greater axis of its central portion ex' tending transverse to the frame and having thegreater axis of each of thehooked end portions extending parallel to the frame.

In testimony whereof, I have hereunto signed my-nan e in thepresenceoftwo witnesses. 7 V g g g V JACOB KAUFMANNQ V lVitnesses I G120; H. (3mm, j
