Application led September 21, 191:4. 'Serial No. 8664!,680.l

To all whom it may concern:

Be it known that I, WAI/IER KENNEDY, residing at Pittsburgh, inthe county -of Allegheny and State of Pennsylvania, a citizen 'of the United States, have invented or discovered certain new and useful Improvements in Universal Couplings, of which improvements the following is a specification.

The invention describedherein relates to certain improvements in couplings for connecting rotatable parts driven one by the other, the coupling being so constructed as to permit ofone of the parts being shifted out of alinement with the other part, while maintaining operative engagement with the y latter.

The invention is hereinafter more full-y described and claimed.

In the accompanying drawings forming a part of this specification, Figures 1 and 2 are elevations at right angles one to the other of my improved coupling; Figs. 3 and 4 are sectional views of the same, the planes of section being indicated bv the lines III- III and IV-IV Fig. 5; Fig. 5 is a transverse section through the coupling; Fig. 6 is a perspective view of the intermediate or connecting block; Figs. 7 and 8 are views similar to Figs. 3 and 4 illustrating` a modification of the coupling, and Fig. 9 is a transverse section on a plane indicated by the line IX--IX Fig. 8'; Figs.l 10 and 11 are sectional views taken on planes at right angles to each other illustrating certain modifications.

Thile the invention described herein is shown as connecting the neck of a roll with its driving spindle, it will be understood that the improvement is euuallv adapted for connecting any driving and driven rotataole parts. As shown in Figs. 1 and 4 the spindle or shaft 1 is provided at its end with diametrically arranged lugs z projecting substantially parallel with the axis ofA across thc end of the neck of the roll. This rib cess 16 in one of the lugs 2.

extends into a groove 7 formed in one side of the block and extending 'diametrically across the block at right angles to the notches 3. As will be seen by reference to Figs. 1, 2, 3 'and 6, the side of the block in which the groove is formed is inclined in opposite direction .from a diametric line at right angles -to the groove and the rib 6 is somewhat shorter than the depth of the groove, so that the block can oscillate on the ridge b or apex of the inclined surfaces of the block. l

In orde-r to prevent the block from mov ing transversely out of engagement with the rib, a pin 8 is passed through the side walls of the groove in the block and through the rib 6, the hole in the rib .being made suiiiciently larger than the pin to permit of the angular shifting of the block. As it is generally impracticable to disengage the coupling membersf by a longitudinal movement of the parts connected, a hole 9 is formed through one or both of the lugs 2V -pin 8, a longitudinallv removable bolt 10 may be emnloved for locking the block and rib together transversely. As shown in Figs. 7 and 8. the rib is notched and an axial hole is formed longitudinally in the part carrying the rib for the reception of the locking bolt. Through the wall l2 forming the bottom of the groove 7 isl formed an opening for the reception of the end of the bolt. said opening being made larger than the bolt in a direction parallel with the groove so that the bolt when in engagement with the block will not interfere with the angular shifting of the latter. The bolt can be shifted into and out of enga gement with the block bv a. pin 13 arranged in a slot 14 andengaging the bolt.

In Figs. v10 and 11. the pin 8a holding the block 4 and rib- 6 in operative relation is provided with a head and at its opposite end with a stem 15 which extends into a re- This stem is threaded for the reception of a nut 17 and betweenthe bottom of the recess 16 and the nut is interposed a spring 18. As the ten bearing surfaces of the lugs and rib by plates of brass or other suitable metal detachably secured to said parts.

No claim is made herein` specifically to the construction shown in Figs. 7, 8 and 9 as such construction per se forms the subject-matter of another application.

It is characteristic of my improvement that the lugs and the rib on the parts or members to be connected overlap and that portions of the member or block through which motion is transmitted are interposed between these overlapping lugs and rib. By reasonof such construction the transmitting block is subjected to pressure and not to any material torsional strain.

- I claim herein as 4my invention:

1. A coupling comprising driving and driven rotatable parts, one of said parts having lugs and the other part being provided With a rib extending across its end, in combination with a block provided with eripheral notches for the reception of said ugs and with a groove for the reception of said rib, the lugs and rib slidably bearing against the side Walls of the notches and groove and the lugs movable longitudinally in the notches to permit of the .driving or driven parts being shifted to angular position one to the' other. V Y

2. A coupling comprising driving and driven rotatable parts, one of said parts having lugsyand the other part being provided with a rib extending across its end, in combination with a block provided with peripheral notches for the reception of said lugs and with a groove for the reception of said rib, the lugs and rib slidably bearing against ently of the block in directions substantiallyat right angles to the direction of rotation of the coupling and a pin engaging the block and a portion projecting into engagement with the block.

4. A coupling h ving in combination driving and driven r tatable parts,a connecting block, the driving`and driven parts having portions projecting therefrom and positively engaging the block in planes at right angles to each other, said parts being movable to4 angular positions relative one -to the other while maintaining engagement with the block,one of said parts being movable relative to the block in the direction of the axis of rotation of said part, and means for preventing the block from moving relative to the other part in the direction of the axis of rotation of said part.

In testimony whereof I have hereunto set my hand.

WALTER KENNEDY.
