Description

` waited tang WILLIA'MKEAN, OFGHIGAG, ILLINOIS.
LettersPatent No. 111,550, dated February 7, 1871.
IMPROVEMENT IN COUPLINGS FOR'SHAFTSFOR-MLLS.
The Schedule referred to in these Letters Patent and making part of the same.
T o all whom .fit may concern:
Be it known thatI, .WILLIAM KEAN, of Chicago, in the county of Cook and State of llli11ois,have invented anew and improved Coupling for Shafts;` and I dol hereby-declare that the following is a full, clear, and exact descriptionthereof', which will enable others skilled in thevart to make and' use the same, reference being had to the`.accompanying drawing forming part of this specification, in which- Figure l represents a longitudinal section of i'ny improved coupling.
the shafts, as well as the key, and supports the same. The key Grits a grooved portion oi' said sleeve to lock the same to the shafts.
One end of the'kcy abuts against the square end oi' the groove in the shaft A. The other end, however, is arrested by a dovetaled clutch or block, E, put into a corresponding' aperture or recess at onc end of the, sleeve D, and retain d therein by means of a screw, a. rlhs clutch or lock is applied after the key and sleeve have been properly put on. By this means the ends of the key are bot-h properly covered and prevented from catching, and the key is, furthermore, secured iu placeaud cannot work out.
Having thus described luy invention,
I claim as new and desire to secure `by Letters Patentv rlhe combination of the clutch E and screw a with the sleeve "D, key C, and shafts A B, all arranged
