John Ru,
a .L a y Dec. l2, 195@ J. D. RUST END CLIP FOR COTTON PICKER SPINDLE SLATS Filed Dec. 26, 1947 Patented Dec. 12, 1950 UNITED STATES PATENT OFFICE END CLIP FOR COTTON PICKER SPINDLE SLATS 9 Claims.
My present invention relates to the spindle slats disclosed in my application for patent led March 29, 1944, Serial No. 528,586, now Patent No, 2,440,- 450.
My present invention has for its object to provide a clip of sheet metal that Ican be stamped and assembled without the use of bolts, screws, rivets or welding.
The clip of the present invention is formed with the front and sides integral and the end formed of interlocked parts.
Other objects will be stated or be obvious hereinafter.
To the attainment of the aforesaid objects and ends, invention resides in the novel features of construction, and cooperation of parts and the method by which the desired results are obtained, reference being had to the accompanying drawing in which:
Fig. 1 is a side elevation of a portion of a Slat with my improved end clip applied.
Fig. 2 is a central vertical longitudinal section of the same.
Fig. 3 is a detail top plan view of the improved end clip per se.
Fig. 4 is a iiat view of the clip blank prior to bending the same to form.
In the drawing in which like numerals and letters of reference indicate like parts in all the figures, I represents the sides of the rib, I and I b the rib casing which rib carries a forward wooden bearing strip 2. Felt strips 3 and 4 lie against the strip 2. The rib casings Ia and Ib carry -wooden bearing blocks 9 and IIJ, fiber strips II and felt strips I2.
The backbone which carries the ribs I is indicated by 6, and 5 indicates a fiber strip along an edge of the backbone. 'I designates the spindles which are journalled in the wooden bearing strip 2 and blocks 9 and I0. The spindles 'I have rollers 8 to engage suitable trackage along which the slats are carried to rotate the spindles.
I4 designates the rectangular hinge plate that is secured to the endless chain of the cotton picker and is detachably connected with the slat by means of a locking key I3. All the foregoing parts are well known and per se are not a part of the present invention.
The improved clip of my invention comprises sides I5, having legs I6, angled side portions II which taper from the sides I5 to the integral front wall I8. The legs I6 terminate in converging flanges Iiix which engage the sides of the rib I and prevent accidental withdrawal of the legs from the rib.
I9 designates one part of the end wall of the clip and 23 indicates the other part. The part I9 has an L-shaped slot in one end while the part 23 has a complementary L-shaped tongue 24.
' The part I9 is also provided with a tool .passage or hole 2| and a slot 22 for the retaining lug I4a of the hinge plate I4. The hinge plate has a tool passage I4b which, when in the assembled position of the parts, see Fig. 2, lines up with the hole 2|, so that by inserting a suitable tool through holes 2 I, Mb, the tongue I3l of the key I3 can be depressed to release the catch end I3b from the recess I4a of the hinge plate I4 and permit the key to be withdrawn and free the slat from the hinge plate. The key I3 has the usual offsets I3a to rest on the adjacent edges of the rib sides I in the usual manner.
The blank from which my new and improved clip is formed is shown in Fig. 4 by referenrce to which it will be seen that by bending up the sides I5 along dotted lines 2'I until the sides are parallel and by offsetting the front Wall I8 by bending on the lines 26 and bending up the end sections I9 and 23 on the lines 28 until the sections lie normal to the sides I5 and legs 25 the two end portions I9 and 23 may be interlocked by springing the L-shaped tongue 24 into the L-shaped slot 2l). The front wall I8 is cut down below the lines 28, as at I8 (Fig. 4), to provide a key-way for the key I3.
In manufacturing my improved clip the 'clip is first blanked and formed by means of suitable dies. The tongues 24 are forced into the slots 20 by distorting or springing the material in the process of fabrication before the clip is tempered.
The clip is applied to the rib by springing it into place as will be obvious to those skilled in the art.
The Iclip is, of course, provided With properly spaced holes 28a to slip over the spindles I.
By constructing the clip as shown and described, the necessity for using rivets or welding to hold the parts in proper position is avoided.
From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, operation and advantages of the invention will readily appear to those skilled in the art.
What I claim is:
