UNITED STATES PATENT OFFICE.'
WILLIAM J. SILVER, `OF SALT LAKE CITY, UTAH TERRITORY.
IMPROVEMENT IN SHAFT-COUPLINGS.
Speeiiication forming part of Letters Patent No. 149,798, dated April 14, 1374; application iled f l March l0, 1874.
To all whom it may concern:
Be it known that I, WILLIAM J. SILVER, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented an Iinproved Shaft-Coupling', of which the following is a specification:
My invention relates to certain improvements on that for which Letters Patent No. 142,288 were granted to me August 26, 1873;
and it consists in the combination of a collar' by a center sleeve, D, which tapers toward both ends, and receives two compressionshells B1, B2, having screw-threads formed on their inner ends, which threads run in the same direction, but differ in their pitch, the thread on the shell B1 being ner than that on the shell B2. These shells are connected by a collar or ring-nut, C, having threads corresponding with those on the shells. When the collar isturned to couple the parts, it takes up the difference between the two threads instead of taking up the sum of two threads, as in my patent aforesaid, in which one of the shells has a right-hand thread and the other a left-hand thread. In consequence of this construction, the speed of the collar in turning is retarded, as well as that of the shells in their motion toward each other, so that less power is required to turn the collar, and thus the operation of coupling` is facilitated. The center sleeve D is split, longitudinally, in the saine manner as in my patent aforesaid, and, in addition, it has one or more longitudinal grooves, d, formed in it, whereby its elasticity is increased.
What I claim as new, and desire to secure by Leters Patent, is-
The combination of the collar or ring-nut C, the split sleeve and compression-shells Bl B2, having screw-threads running in the same direction, but di'ering in pitch, substantially as and for the purpose shown and described.
WM. J. SILVER.
