HEDDLE BAR SUPPORT Filed Jan. 26, 1951 lNvENToR FREDERICK M.SUCHKE ATTORNEYS United States Patent HEDDLE BAR SUPPORT Frederick M. Snchke, Atlanta, Ga., assignor to Pioneer Heddle and Reed Company, Incorporated, Atlanta, Ga., a corporation of Georgia Application January 26, 1951, Serial No. 208,616

6 Claims. (Cl. 139-92) In heddle frames for loom harness it is common pracmediate supports for the heddle bars between their ends so as to maintain a substantially rigid or stable heddle bar within the frame.

The present invention relates to above type of support for the heddle bars and contemplates the provision of elements carried by the horizontal rails of the heddle frame and other elements attached to the heddle bars with an interlock or connection of the elements in such manner that the heddle bar will be adequately supported intermediate the end sections of the heddle frame and at the same time provide for a quick and simple release of the elements so as to facilitate easy removal of the heddle bar from the frame as occasion may require. The invention also contemplates the adjustment relatively of the rail of the heddle frame and heddle bar both longitudinally and transversely so as to insure a proper movement of the heddles on the heddle bars during the operation of the loom.

While the invention is especially applicable to heddle frames supporting heddle bars and metallic heddles provided with C-shaped openings as shown in my prior Patent 2,514,298 issued July 4, 1950, it distinguishes from that patent in that the heddle bar supporting arrangement herein disclosed is such that the heddles are free to slide on the heddle bar from end to end without interference with the bar support.

The present invention will be described as associated with the upper horizontal rail and upper heddle bar, it being understood that the support and its connection between the lower rail and lower heddle bar may be identical.

The structural characteristics of the present invention are set forth in detail in the following description and in connection with the accompanying drawings wherein corresponding parts are identified by corresponding marks of reference and wherein Figure l is a side view showing the application of the invention to the rail of a heddle frame and the heddle bar.

Figure 2 is an end view of Figure 1.

Figure 3 is a vertical section through the support on the line 3-3 of Figure 1.

Figure 4 is an end view showing a lifting of the heddle bar and its bracket for detachment from the rail of the heddle frame.

Figure is a sectional view on the line 5-5 of Figure 1.

Figure 6 is a plan view of the inner surface of the plate shown in Figure 5.

Figure 7 is a plan view of the inner surface of the nuts by which the plate is supported and adjusted.

At the desired point or points of support for the heddle bar, screw threaded studs 1 and 2 are turned into the wooden rail 3 of the heddle frame from its inner edge ice a sufiicient distance to insure adequate engagement for load carrying purposes. The protruding ends of the studs may be slotted or flattened as shown in aid of turning and adjustment when required. A bar or plate 4 is provided with openings 5 slightly larger than the studs 1 and 2 so that the bar 4 may move freely along the studs in opposite directions.

Nuts

6 and 7 knurled or provided with flats are rotatable on the studs 1 and 2 to adjust and fix the position of the bar with respect to the rail 3 and heddle bar.

The usual heddle bar 8 for the metallic heddles 9 has aflixed thereto an outwardly extending bracket 10, consisting of the vertical leg portion 11 and horizontal leg portion 12. The vertical leg portion 11 of the bracket 10 is attached to the heddle bar by the use of a spacing block or shim 13 with rivets 14 passing through the bracket shim and bar thus securing these parts together with the result that the vertical leg of the bracket is held spaced from the heddle bar and lies without the plane of the latter. Obviously other means, for example welding or fusion, may be employed to effect a connection of the hcddie bar and bracket.- This arrangement thus permits the heddles of the type shown in my prior Patent 2,514,- 298 to slide freely within the heddle frame along the entire length of the heddle bar regardless of the number of intermediate supports.

The outer portion of the bracket 10 is bent substantially at a right angle to form a horizontal leg portion 12 and is adapted to rest upon and overlie the plate 4.

Fingers

15 and 16 are connected to the plate and extend inwardly therefrom to engage one edge of the bar. These fingers, together with the vertically extending portion 11 of the bracket serve to restrain the bracket against transverse displacement with respect to the plate 4.

The horizontal portion 12 of the bracket between the

fingers

15 and 16 is provided with a slot 17 as shown in Figure 5 to permit the horizontal leg portion 12 to pass a screw 18 turned into the rail 3. The protruding end of this screw passes freely through an opening 19 in the plate 4 and is provided with a slot or flats for turning or adjustment. The slot 17 is by preference substantially wider than the diameter of the screw 18 so as to permit longitudinal movement and adjustment of the bracket and the heddle bar secured thereto. A nut 20 knurled or fiattened as desired rotates on the screw 18 and serves when moved inwardly to hold the plate 4 and horizontal portion 12 of the bracket in tight engagement. When it is desired to disengage the bracket 10 from the plate 4 the nut 20 is loosened and moved outwardly a suflicient distance to permit the bracket to be lifted to a point where the

fingers

15 and 16 will clear the plate 4, see Figure 4, whereupon the bracket may be moved laterally thus separating the elements carried by the rail from those carried by the heddle bar. if desired the rail 3 may be recessed as at 22 to provide adequate clearance for the nut 18 when moved outwardly.

it is desirable to provide for an adjustment of the heddie bar supports so as to insure a proper functioning of the heddles on the heddle bars during operation. To this end adjustment of the

nuts

6 and 7 will permit the heddle bar 8 and the bracket connected thereto to be moved toward or away from the rail 3 the nut 20 being relieved when necessary to permit such adjustment. One or more radial slots 23 adjacent the openings 5 in the plate 4 in cooperation with one or more lugs 24 formed on the inner surface of the

nuts

6 and 7 serve to lock the nuts in a selected position when the nut 20 is finally tightened to secure the bar and bracket together.
