INVENTOR. AaZieqnS/aZcZsbZZZ Patented Sept. 12, 1944 UNITED STATES PATENT OFFICE HEDDILEI BAR SUPPORT Author Shields Holt, Goldville, S. 0.

Application August 3, 1943, Serial No. 497,199 6 Claims. (01. 139-92) This invention relates to heddle bar supports, and its general object is to provide a support which makes it possible to easily and expeditiously release the heddles, in the event they become held against free sidewise movement on the bars thereof, it being obvious that the bars must be maintained in perfect parallelism with each other, to prevent binding of the heddles thereon, and at times the top and bottom rails of the heddle frame become distorted which results in throwing the bars out of parallelism and the heddles become jammed thus causing imperfections in the weave, but such difficulty is entirely overcome by the use of my supports.

A further object is to provide a heddle bar support which allows ready application and removal of the bars with respect thereto, but casual removal is practical impossible.

Another object is to provide a heddle bar support that is adjustable relative to the rails of the frame, and the support is simple in construction, inexpensive to manufacture, and extreme- -1y efficient in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustraed in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a view partially in section of the support which forms the subject matter of the mounted within a bore 2 in the rail A for free present invention attached to the upper rail of the heddle frame and has a pair of heddle bars clamped therein, as the support shown is for use with a double set of heddles.

Figure 2 is a sectional view taken approximately on line 22 of Figure 1.

Figure 3 is a perspective view of the sliding plat element for connecting the clamp for the bars to the rail attached bolt.

Figure 4 illustrates one of the clamping elements for the bars and with parts thereof separated and in perspective.

Figure 5 is a perspective view of the removable clamping element for the bars.

Referring to the drawing in detail, the letter A indicates the upper rail of a heddle frame and B the upper heddle bars, its being understood that a frame includes upper and lower rails connected together at their ends by side strips which have upper and lower bars bridging and conrotation and is threaded in a nut 3 that is held against rotation within a transverse bore 4 in the rail, as clearly shown in, Figure 1. The head 5 of the bolt is of elongated rectangular formation, and threaded on the stem is a disklike adjusting nut 6 having a serrated periphery. By that construction, it will be obvious that the bolt is adjustable relative to the rail for adjusting the position of the bars accordingly.

The element for connecting the clamp of the bars B to the head 5 of the stem includes an elongated rectangular plate 1 having flanges 8 formed thereon along the longitudinal edges thereof and disposed at right angles thereto, as best shown in Figure 3. Formed on and bridging the outer edges of the flanges is a cross member 9 having a center hole l0 therein, the hole having threaded therein a stud ll formed on one end of a strip like member I2 which has riveted or otherwise secured to the opposite flat faces thereof a pair of flat clamping members, each including substantially T-shaped portion l3 and an arcuate portion l4 formed on the T-shaped portion, in a manner so that the clamping members provide lateral seats l5 for receiving the bars therein, as bestshown in Figure 2. The walls [6 of the seats are recessed to prevent lateral displacement of the bars therefrom.

Cooperating with the fiat clamping members is a spring pressed clamping member that is formed from asingle strip of sheet metal to provide a substantially square body H having a central hole therein for mounting this clamping member on the stud II for slidable movement, and formed on the fiat body 11 and extending from one side thereof is a pair of arms l8 that against the opposite longitudinal edges thereof, as shown in Figure 2.

The movable or spring pressed clamping member is urged and held in clamping engagement with the bars, by a coil spring 20 sleeved on the stud H and bearing against the cross member 9 and the body I'I. By that construction, it will be obvious that the bars can be easily and expeditiously applied and removed with respect to the clamp, and are held therein against any possibility of casual removal.

The elongated rectangular plate I is provided with a slot 2| extending along the longitudinal center thereof, for the major portion of its length,

the head 5 bearing against the inner face of the plate I, as shown in Figures 1 and 2. Sleeved on the stem and bearing against the disk like adjusting nut 6 and the outer face of the plate I is a coil spring 22 that acts to hold the connecting member which is broadly indicated by the reference numeral 23 against sliding movement on the head 5 under normal conditions. However, in the event the rails of the heddle frame should become distorted for any reason, and throw the bars out of parallelism, which, causes the heddles to bind, and become jammed, the connecting member 23 will slide out of normal position, but upon releasing the same relative to the head 5, through the medium of the adjusting nut 6, the bars will automatically assume their normal parallel position and thus allow free movement of the heddles thereon.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall pended claims. What I claim is: l. A support for the bars of a Within the scope of the apheddle frame,

comprising clamping means for the bars, a headed bolt secured to a rail of the frame, means slidably mounted on the head of the bolt and having the clamping means connected thereto, and spring means for holding the slidably mounted means against movement and being releashaving the clamping means connected thereto,

an adjusting nut threaded on the bolt, a spring sleeved on the bolt between the nut and the slidably mounted means for holding the latter ed bolt adjustably secured to the rail of the frame, means connecting the clamping means to the bolt and including an elongated plate s1id-' ably mounted on the head of the bolt, parallel flanges formed on the plate, a cross member secured to and bridging the flanges and having the clamping means connected thereto, a nut threaded on the bolt, and a spring sleeved on the bolt between the nut and the plate for holding said connecting means against movement on the head.

4. A support for the bars of a heddle frame, comprising clamping means for the bars, a headed bolt secured to a rail of the frame, means slidably mounted on the head of the bolt and having the clamping means connected thereto, spring means forholding the slidably mounted means against movement and being releasable therefrom to allow movement thereof, said clamping means. including a stud threaded in the slidably mounted means, a striplike member formed on the stud, fiat clamping members fixed to the striplike member and including seats having the bars mounted therein, and a spring pressed clamping member slidably mounted on the stud and cooperating with the flat clamping members for holding the bars in the seats.

5. A support for the bars of a heddle frame, comprising clamping means for the bars, a headed bolt secured to a rail of the frame, means spring means for holding the slidably mounted means against movement and being releasable therefrom to allow movement thereof, said clamping means including a stud threaded in the slidably mounted means, a striplike member formed on the stud, flat clamping members fixed to the striplike member and including seats having the bars mounted therein, and a spring pressed clamping member including a fiat body slidably mounted on the stud, a pair of arms formed on and extending from one side of said body and being bent to bear against a flat face of the body, said arms extending in spaced parallel relation from said face and having recessed free ends providing seats with the bars mounted therein for cooperation with the first seats to prevent casual removal of the bars therefrom.

6. A support for the bars of a heddle frame,

, comprising clamping means having slidably inagainst movement, and said spring being releasable by the nut to allow movement of the slidably mounted means. 3. A support for the bars of a heddleframe, comprising clamping means for: the bars, a headterfitted bridging members for the bars, means adjustably connecting the clamping means to a rail of the frame and having slidably interfitted head and slot connections with the clamping means, and an adjustably tensioned spring means'normally holding said connections against undue movement and being releasable to allow the bars to return to a normal position in the event they should become out of parallelism with each other. j
