CENTER BAR FOR HEDDLE FRAMES Filed Jan. 24, 1939 Patented Oct. 31, 1939 UNITED STATES PATENT OFFICE Watson-Williams Manufacturing Company,

Millbury, Mass., a corporation of Massachusctts Application January 24, 1939, Serial No. 252,626

4 Claims.

This invention relates to frames in which loom heddles are mounted. These frames commonly comprise top, bottom and side frame members and heddle bars extending through and secured to the side members. In wide frames, it is also desirable to provide one or more center bars which firmly connect the top and bottom frame members at intermediate points and which also provide intermediate support for the heddle bars.

It is the general object of my invention to provide improved means for attaching a center bar to the top and bottom frame members and for positioning heddle bars therein.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing, in which Fig. l is a partial front elevation of a heddle frame having my invention embodied therein;

Fig. 2 is anenlarged partial front elevation of the lower end of a center bar and its attaching means;

Fig. 3 is a sectional side elevation, taken along the line 33 in Fig. 2; and

Fig. 4 is a detail side elevation, showing certain parts in a dififerent position.

Referring to the drawing, I have shown a portion of a heddle frame comprising a top frame member it, a bottom frame member ll, side frame members I2 and I3, and upper and lower heddle bars M and [5 on which wire or steel heddles H are slidably mounted. The heddle bars 35 i i and i5 extend through the side frame members if and I3 and are commonly secured in place by latches 56. All of the parts thus far described are of the usual construction.

My improved center bar comprises a bar 20 having openings 21 in its opposite ends to receive the offset ends 22 of hooks 23 which are screwed into the frame members it) and II respectively. At each end, the bar 20 is cut away as indicated at 25 and is provided with a projecting portion 26 45 forming one side of a slot or opening 21 in which the heddle bars id or 5 may be seated.

A latch 39 is pivoted at 3| at each end of the bar 29, and at its lower end the latch is provided with a transverse lug 32 adapted to enter a hole 35 extending crosswise of the portion 22 of the hook 23. Each latch 30 is also provided with a projection 3'lforming one side of a slot 38, also adapted to receive a heddle bar M or IS.

The parts are assembled by inserting the bar 20 so that the portions 22 of the hooks 23 extend through the openings 2| in the bar, and by then swinging the latches 30 so that the lugs 32 will be projected through the holes 35 in the hooks 23. The parts are then in the position shown in Fig. 3.

A heddle bar, as l5, mounted in the slots 2'! and 38 will then look the latch in holding position and will prevent accidental displacement of the center bar.

It will thus be seen that my improved center bar has only one additional moving part to cooperate with each hook 23, and that no springs or other detachable or breakable elements are required.

My improved center bar may thus be very easily and economically manufactured and is particularly Well adapted for its intended purposes.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a heddle frame, a center bar having openings through each end, offset hooks on the inner edges of the top and bottom members of said heddle frame which are insertable through said openings transversely to said bar, and latches pivoted on said center bar and directly engaging and coacting with said offset hooks to secure said bar and hooks in assembled relation.

2. The combination in a heddle frame as set forth in claim 1, in which slots are provided in said center bar and in said latches to receive heddle bars, said slots being aligned when the latches are in holding position and said latches being locked in holding position by said heddle bars.

3. In a heddle frame, a center bar having openings through each end, offset hooks secured in the top and bottom members of said heddle frame and insertable through said openings, said hooks having holes extending crosswise through the offset portions thereof, and latches pivoted on said center bar and having portions insertable in said cross holes when said bar is assembled with said hooks.

4. In a heddle frame, a center bar having openings through each end, devices on the inner edges of the top and bottom members of said heddle frame which are insertable through said openings transversely of said bar, latches pivoted on said center bar and directly engaging and coacting with said devices to secure said bar and devices in assembled relation, and means tolock said latches.
