SPECIFICATION forming part of Letters Patent No. 709,992, dated September 30, 1902. Application filed May 2,1902. Serial No. 105,680. (No model.)
To all whom it may concern.-
Be it known that LALLAN G.MATHER,a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Universal Couplings, of which the following is a specification.
My present invention pertains to improvements in shaft-couplings, the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein- Figure 1 is an end elevation of the coupling, the shaft being shown in section; Fig.
I5 2, a side elevation, the upper portion thereof being shown in section; Fig. 3, a side elevation of the intermediate or uniting member of the coupling; Fig. 4, a face view of the same; Figs. 5 and 6, side and face elevations of the connecting-straps; Figs. 7 and 8, similar views of the driving members which are secured to the shaft; and Fig. 9, a perspective view of one of the connecting-bolts, shoulder-pins, and rollers.
The present coupling is especially adapted for connecting together shafts which are slightly out ofline and whose axes do notintersect. The axes of various sections ofline-shaft ing are usually parallel, but frequently out of axial alinement from nothing to three-eighths of an inch, and it is to take care of such slight variations that the present coupling was designed. The present coupling is therefore especially applicable for use in connecting up a series of shaft-sections where each section carries a grinding-roll and where it is desirable at times to move any one or more of the rolls away from its opposite companion roll and still continue to drive the entire line of rolls notwithstanding the fact that the shaft-sections are thrown out of alinement.
In a previous application filed by me on or,
about the 29th day of October, 1901, I have shown, described, and claimedthis arrangement of grinding-rolls, but with a specifically difierent form of coupling.
In the present coupling the parts attached to each shaft section or end are duplicates and interchangeable, so that in the following description the same reference-letters apply equally well to both sets.
Referring to Figs. 1 and 2, A denotes the shaft, to which iskeyed a driver 13, said driver being formed with a central hub, which embraces the shaft, and with diametrically-disposed arms C. In each of the arms there is formed a socket or recess D, with a bolt-hole E extending from the base of the socket to the outer face of the driver. Seated within the sockets thus formed are shoulder-pins F, the larger outer end of each pin carrying a roller G. The drivers on the opposite shaft ends are arranged crosswise to each other, so that the rollers G when the parts are assembled may pass into the milled slots H of the intermediate block I, or cross, as it may be termed. As will be noted'upon reference to Figs. 1 and 2, these slots are deeper than the diameter of the rollers, so that the parts may move out of axial alinement a certain extent. The rollers have a fair bearing on the straight walls a, which define the side of the slots or ways, so that there is no lost motion, while at the same time an extended wearing-surface is afforded. \Vhen the rollers are in position in the slots in the cross or intermediate block, straps J, one for each driver and its rollers, are passed down upon opposite sides of the block. Bolts K are then passed through openings formed in the ends of the straps, through coincident openings in the shoulder-pins F, and through the openings E in the driver, being secured in place by nuts L. From this it will be seen that the two shaft-sections are securely coupled together, the drivers and the straps embracing the intermediate block or cross and causing the shaft-sections to rotate together, while still permitting them to be moved out of axial alinement to a limited extent.
The construction set forth is strong and durable, and the extended bearing-surface afforded to those parts subjected to strain and wear reduces the wear to a minimum. Furthermore, the parts may be readily replaced when necessary.
Having thus described my invention, what I claim is 1. In a coupling, the combination of a pair ofshafts; adriver rigidlyaffixed to each shaft, each driver having a pair of outwardly-extending arms, the arms of one driver being placed at right angles to those of the other; a roller extending outwardly from the end of each arm; a slotted block located intermediate the arms with the rollers extending into the slots; and means for securing the block to the drivers.
2. In a coupling, the combination of a pair ofshafts; adriver rigidly afiixed to each shaft, each driver having a pair of outwardly-extending arms, the arms of one driver being placed at right angles to those of the other; a roller extending outwardly from each arm at right angles thereto; a block located between the arms of the drivers, said block being provided with radial slots into which the rollers extend; a strap passed down upon each side of the block; and means for securing each strap to the driver which occupies a position upon the opposite side of the block therefrom.
3. In a coupling, the combination of a pair of shafts; a driver rigidly affixed to each shaft, each driver having a pair of outwardly-extending arms, and each arm having a socket formed therein; shoulder-pins seated in said sockets; rollers carried by the outer ends of said pins; a block located between the arms of the drivers, said block being formed with a series of radial slots into which the rollers pass; straps passed down upon opposite sides of the block in line with the ends of the rollers; and bolts extending through the straps, the shoulder-pins and the'drivers.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ALLAN G. MATHER.
