UNITED STATES PATENT OFFICE.
ROBERT POOLE, OE BALTIMORE, MARYLAND, ASSIGNOR TO POOLE 86 HUNT,
. OF SAME PLAGE.
IMPROVEMENT IN SHAFT-COUPLINGS. n'
Specification forming part of Letters Patent No. 181,473, dated August 22, 1876; application filed l August 7, 1876.
To all whom it may concern:
Be it known that I, ROBERT POOLE, of the city of Baltimore and Sta-te of Maryland, have invented certain new and useful Improvemciits in Couplings for Shafting, of which the following is a specification:
My invention relates to the well-known class of couplings in which the ends of the shaftsections are secured together by an enveloping split sleeve, a key, and screw-nuts Working on the ends of the sleeve.
The objects of my invention and the subject-matter claimed will hereinafter specically be designated. v
In the accompanying drawings, which show so much of my improvements as is necessary to illustrate the subject-matter claimed, Figure l is a longitudinal central section through` the apparatus on the line I l of Fig. 2, and Fig. 2 a transverse section therethrough on the line 2 2 of Eig. l.
The ends of the shaft-sections Al A are grooved longitudinally for the reception of a key, b, carried by a longitudinally split sleeve,
i B, adapted to envelop the ends `of the shaftsections in a well-known way. The periphery of this enveloping-sleeve tapers from-a point at or near its center toward each end, and these tapering surfaces are provided with screwthreads for the reception ofk correspondingly# threaded clamping-nuts C O'.
The construction of this enveloping-sleeve is peculiar, it being so formed as to be slightly elliptical, as is clearly shown in Fig. 2, the axis of the longer diameter being one at right angles to thesplit in the sleeve, but both axes being coucentricwith the axis of the shaft.
By this mode of construction the sleeve is rendered capable of yielding more readily to the action of the clamping-nuts, and consequently greater friction can .thereby be produced'between it and the ends of the shaftsections than is practicable with the ordinary split sleeve.
The sleeve, it will be observed, is grooved 'or recessed for the reception ofthe key b, at a point directly opposite its dividing-slot, which still further adds to the elasticity of the sleeve and its efficiency'.
The manipulation of couplings of this description is well understood, and the advantages of my improvements Will be obvious to those skilled iu the art.
I am aware that both round and eccentric split sleeves have heretofore been suggested in connection with shaft-couplings, and I do not broadly claim such device.
I claim as of my own invention- The combination, substantially as hereinbefore set forth, of the grooved shafting, the
`elliptic tapering split sleeve enveloping the shafting, the key carried by said sleeve, and theclamping-nuts working on the inclined surfaces ofthe sleeve.
In testimony whereof I have hereunto sub-
