UNITED STATES PATENT OFFICE.
JOSEPH F. LIGHT, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO WOOD & LIGHT MACHINE CO., OF SAME PLACE.
IMPROVEMENT IN SHAFT-COUPLINC-TS.
Specification forming part of Letters Patent No. 155,837, dated October 13, 1&74; application tiled July 20, 1874.
To all whom t may concern:
Be it known that I, JOSEPH F. LIGHT, of Worcester, in the county of Worcester and State of Massachusetts, have invented a new Improvement in Coupling for Shafting; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be afull, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-
Figure l, a side view; Fig. 2, a longitudinal central section, and in Fig. 3, a transverse section.
This invention relates to an improvement in a device for coupling lengths of shafting together; and it consists, first, in a pair of clamps to inclose the meeting-ends of two lengths of shafting, the coupling constructed with a cavity between the center and each end of the coupling, and a corresponding cavity iu each length of shafting, and placing in the said cavities a ball or block corresponding to the shape of the cavity, so that, when the coupling is clamped together, the said balls or blocks will securely unite or couple the two lengths of shafting.
A is the one part, and B the other part, of the coupling. Each of the parts are semicylindrical, and longitudinally through the center is a recess corresponding to the ends of the shafts to be coupled. In one part, B, of the coupling (or may be in both) I form a cavity, a, between the center and ends; this, preferably, of a semi-spherical shape. C and D are the meeting-ends of two pieces of shafting to be coupled. In each of these is formed a cavity, d, corresponding to the cavity a in the coupling.
Previous to placing the part B upon the shaft, a ball, f, is laid into each of the cavities 5 then the two parts of the coupling set in place, the balls entering the corresponding cavity in the two shafts, as seen in Fig. 2. The two parts are then firmly secured together, and the balls f prevent the movement of either ot' the shafts, except with the couplingthat is to say, the shafts cannot separate longitudinally, or either turn with the coupling without the other. y y
While I prefer the ball shape, I donot wish to be understood as confining myself to this shape, as the other shape blocks will answer the same purpose; therefore, in the use of the term ball, I wish to be understood as embracing any of the shapes that may be substituted therefor.
To unite the two parts, and in order not to interfere with the cylindrical form of the two parts, l construct them with cavities E, one surface of the cavity being substantially parallel to the meeting-faces ofthe parts, and the other at substantially right angles thereto, as seenin Fig. 3. Through the meeting-parts screws or bolts L are set, as seen inFig. 3, so that the heads (and nuts, if' they be used,) will be in these cavities, within the circumference. of the coupling, as seen in Fig. 3, so that, it' desired, a pulley may be set onto the coupling, or the coupling itself used as a pulley.
I claim- The herein-described shaft-coupling, consisting of the two parts A B, in one or both of which cavities a are formed, and corresponding cavities d in the respective ends otl the shafts to be coupled, combined with the balls f, substantially as set forth.
J osEPH A. -HoWLANn, OTIs WARREN.
