Description
UNITED STATEs PATENT OEEIcE.
BENJAMIN ROAOH, OF MELROSE, MASSACHUSETTS.
IMPROVEMENT IN SH`AFTCOUPLINGS.
Specification forming part of Letters Patent N0. 57,771, dated September 4, 1866.
To all whom it may concern:
Be it known that I, BENJAMIN RoAoH, of Melrose, in the county of Middlesex and State of Massachusetts, have invented an Improved Shaft-Coupling 5 and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a top view of two shafts provided with my invention. Fig. 2 is ahorizontal section, and Fig. 3 a vertical section of the same/ In the drawings, A and B are the two shafts arranged with their axes in one straight line, each shaft being provided with a coupling head, (l, which has agroove, a, made diametrically across its inner face.
The two couplingheads 'are arranged at a short distance asunder-thatis, one sufficient to receive a disk, D, which is provided with two ribs, b b, extending diametrically across it, and one being in one and the other being in the other side of it. These ribs are formed to it into the grooves a aI otl the two coup- 1ing-heads. One or more screws or bolts, c c, go through the two heads and the disk, and serve to hold them together. p
With the common coupling composed of two heads united by screw-bolts there is a tendency of one of the heads rubbing against the other when the screws or screw-bolts are out of the heads, and one of the shafts is in revolution. -This contact of one head with the other causes wear and friction, which it is desirable to avoid.
When the bolts of my improved coupling are removed the disk can easily be drawn out from between the two heads, so as-to leave the heads at such a distance apart as to prevent their coming together and one rubbing against the other.
The ribs of the disk, by their eo-operation with the recesses or grooves in the heads, receive the torsion-strain of one head on the other, and thus serve to relieve the connecting-bolts from such strain.
What I claim isrJhe arrangement and combination of the disk D and its ribs b b with the two couplingheads O C, provided with grooves a a, arranged in them to receive the ribs, as set forth.
BENJAMIN ROAGH. Witnesses:
R. H. EDDY, It. P. HALE, Jr.
