vUNITED smrss nisse? PATENT OFFICE HEDDLE FRAIVIE Louis Kasper, Philadelphia, Pa., assignor to Steel Heddle Manufacturing Company, Philadelphia, Pa., a corporation of Pennsylvania Application July 16, 1935, Serial No. 31,552 1 9 Claims.

` heddle bar support Whichwill receive and hold a heddle supporting barintermediate the ends of the4 bar and will prevent movement and dis- `1() placement of the heddlebar, but which Will permit easy and quick removal of the heddle supporting bar from. the harness frame when desired.

A further object of the invention is to provide a heddle bar support which will be spring pressed-to locking position and will be self-locking, but which may be readily released and actuated to a position to permit the removal of the heddle bar.

A further objectof the-invention is to provide a heddle bar support which Will contain within itself means for automatically locking a heddle bar in fixed position.`

A further object of the invention is to provide a heddle bar support which will be simple and inexpensive in construction, yet sturdy and reliable in operation. Other objects of the invention Will appear from the specification and claims.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which: Y

Figure 1 is an elevational View of a heddle frame provided with heddle bar supporting devices embodying the main features of the present invention;

Fig. 2 is an enlarged fragmentary side elevational view partly in section, illustrating one of the supporting devices, the same being Ashovvn in conjunction With a portion of the rail of the heddle frame on which it is mounted, and showing the partsY in position to lock the heddle bar in position;

Fig. 3 is 7avieW similar to Fig. 2, but showing the supporting device in the openl' position for the insertion or removal of a heddle supporting bar;

Fig. 4 is an enlarged sectional View, taken approximately on the line 4-4 of Fig. 1 and showing the parts in the locked heddle bar supporting position, as in Fig. 2; and

Fig. 5 is a sectional plan View taken on the line 5-5 of Fig. 3.V z

It will, of course, be understood that the description and drawing hereinrcontained are illustrative merely, and that various modifications and changes may be made in the structure disclosed Without departing from the spirit of the invention.

Referring to the drawing, the heddle frame there shown comprises top and bottom rails l0, connected at their ends by means of side strips I-Ieddle supporting bars, as `at |2,extend from end to end of the heddle frame, near the top and bottom rails IIJ. on the heddle supporting bars |2 in the usual manner. A.

'Ihe heddle bar supporting devices comprising the improvement of the present invention are Heddles I3 are mounted mounted at suitable locations on the inner edges of the top and bottom railsv I0. Each of the heddle bar supporting devices includes a pin or bolt member 20, having a shank 2|, and theend portion thereof is threaded for engagement with the wooden rails E, as at 22, in a manner similar to an ordinary wood screw, with the exception that the same is not tapered for the greater portion of its length.-

The bolt member 20 is also provided with a fiattened head portion 23, offset as at 24 with respect to the vertical axis of the shank 2 I, so that one face thereof, as at 25, is substantially 4in alinement with the outside of the shank 2 I. The head portion 23 is preferably made by flattening and spreading the material of the rod from Which the bolt member 20 is formed. l

The flattened head portion 23 is recessed as at 26, and a notched shoulder 21 is provided for heddle bar engagement. A shoulder 28, provided at the opposite end of the recess 2B, is slightly inclined as indicated in Fig. 4, to facilitate the insertion and removal of the heddle supporting bar I2. f

` A slidable heddle bar clamping member 29 is mounted on the face of the attened head portion 25 of the bolt member-20, and includes, at the end thereof toward the free end of the pin 20, a slotted portion 30 for direct engagement with the edge portion of the heddle bar |2.

The other end of the bar clamping member 29 is bent over, as at 3|, perpendicular to the axis of the shank portion 2| of the bolt member 20, and is provided with an aperture 32 through which the shank portion 2| extends, so that vertical sliding movement of the Ybent over portion 3| along the shank 2| iscreadily effected.

The other end portion of the bar clamping member 29, which carries the slotted portion 3l),

is positionedwith respect to the head portion 23 55 of the bolt member by means of a rivet 33 which extends through a slot 34 in the bar clamping member 29. The slot 34 serves also to limit the movement of the bar clamping member 29 along the pin 20, and prevents said member from moving an excessive distance toward the free end of the bolt member 2|) when no supporting bar is seated within the recess 26.

A locking lever member is provided as at 35, having an aperture 36 therethrough, the Width of which is substantially equal to, but the length of which is slightly greater than the diameter of the shank 2|, to permit the lever member 35 to assume the angular or inclined locking position shown in Fig. 2.

'I'he lever member 35 has a bent over end portion, as at 31, with a tongue 38 extending into a cut out portion 39 of the slidable clamping member 29. The tongue 38 and the out out portion 39 provide, With the top of the bent over portion 3 I, a suitable pivotal or hinge connection and a fulcrum for the lever 35. The end of the lever member 35 opposite the end portion 3l is bent back as at 40, to provide a lip 4| for engagement with a face of the bent over portion 3 I.

The lip 4I furnishes a part for engagement by the operator, and is so arranged that the lever 35 may be swung from the angular position, as shown in Fig. 2 to a position parallel to the bent over portion 3| of the clamping member 29, as shown in Fig. 3. 'Ihe movement of the lever member35 to the parallel position, as shown in Fig. 3, is limited by the engagement of the back turned lip portion 4| with the under face of the bent over portion 3| of the clamping member 29. In this latter position, the clamping member 29 is unlocked, and may thereafter be easily moved to a position to permit the insertion or removal of the heddle bar I2.

A coil spring 42 is mounted on the shank 2| of the bolt member 20. The coil spring 42 bears at one end against the locking lever member 35 and at the other end against struck up portions 43 on the shank 2|, if it is desired to provide a predetermined tension not varied by the adjustment of the bolt 20 in the rails; or this latter end may bear against a portion of the rail if desired.

The operation o1 the device will now be readily understood. In the position prior to the insertion of a heddle bar I2, the locking lever member 35 is at an angle, somewhat as shown in Fig. 2, and assuming that it is desired to mount a heddle bar I2 in the support, the locking lever 35 is rst pushed manually to a position parallel to the bent over portion 3|, by application of force to the bent under portion 4I and against the tension of the coil spring 42. Upon the continued application of force the locking lever member 35 and the slidable bar clamping member 29 are moved together to the position shown in Fig. 3.

The heddle bar I2 may then be inserted in the recess 26, and the manual force Withdrawn. The coil spring 42 then forces the locking lever 35 and the slidable clamping member 29 toward the free end of the bolt member 20 until further movement is prevented by engagement of the end of the slotted portion 30 with one edge portion of the heddle bar I2, the other edge portion of the bar being held in engagement With the shoulder 21 of the bolt member 2|).

The coil spring 42 maintains the locking lever 35 in the inclined position as shown in Fig. 2, and any force exerted by the rod I2 on the slidable clamping member 29 is transmitted through its fuicrum to the locking lever 35. The

engagement between the inner portions of the aperture 36 of thelocking lever 35, and the shank portion 2|, is made tighter and iirmer as the force is increased, While at the same time the spring 42 assists in maintaining the locking lever 35 in its locking position. It Will thus be seen that the device is self-locking at all times when a heddle bar I2 is in the recess 26.

If it is desired at any time to remove the heddle bar I2, it is a relatively simple matter to operate the device in the manner pointed out above for the initial insertion of the heddle bar I2.
