UNITED STATES PATENT OEEIGEo EDGAR B. BEACH, OF VVES'I MERIDEN, CONNECTICUT.
IMPROVEMENT IN OAR-LOCKS.
Specification forming part of Letters Patent No. 148,279, dated March 10, 1874; application filed February 10, 1874.
To all whom it may concern:
Beit known that I, EDGAR B. BEACH, of Test Meriden, county of New Haven, State ot' Connecticut, have invented a new and useful Improvement in Oar Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing makin g part of this speciiication, in which- Figure l is an elevation of my improved oar-lock, with its bearing shown in section; Fig. 2, a sketch illustrating the mode of application to a boat; Fig. 3, a modilication, showing the application of my invention to a easter.
My invention relates to selfsupporting swivel-bearings; and it consists of a shank of an oar-lock, caster, or other analogous article, which is designed to swivel, constructed with a short screw-thread of the same diameter as that of the shank, said thread being at the upper extremity oi' a stem at the end ofthe shank, in combination with a bearing box or tube, in which the shank swivels, constructed with a short nut matching the short screw, the said parts being united by passing the shank through the box or tube, and screwing up until the screw disen gages from the thread in the nut, and passes out beyond the chamber of the box or tube, and when out, answers as a rotary flange, to prevent the shank dropping out of this box, while the shank is free to swivel.
A in Fig. l represents a metallic oar-lock of ordinary construction, with a shoulder, A, which sits and has its vertical bearing on the plate b of the swivel-bearing box B. The shank C of the said oar-lock tits into the box B, and near its end is provided with a stem, c, of reduced diameter, and at the end of the said stem with a screw-thread, D, ofthe same diameter as the'shank. The swivel-box B is also provided with a screw-thread, d, which matches the screw-thread D on the shank C,
but the swivelbox terminates where the thread D begins, so that the said thread is outside of the swivel, as shown in Fig. 1, when in operation. In this position the'thread d acts as a retaining-ilange, and prevents the slipping of the shank C out of the swivebbox.
If it is desirable to remove the oar-lock, it may be unscrewed with a little pressure upward.
As it is necessary to remove the oar-locks from a boat when not occupied, to prevent unauthorized persons from using or breaking them, (or from stealing them when they are made of costly met-ah) this is the most economical and convenient method of constructing them, so they may be removed and reapplied without unfastening the swivel-boxes, while at the same time they are secured against lifting up out of their bearings when in use.
In Fig. 3 I have shown my invention applied to a caster, E, on the leg F of a table or other piece of furniture, the same combination of shank C, shoulder c, stem c, screws D and d, and swivel-box B being used, and when thus applied the easter will be retained in proper position upon the leg though the table be lifted from the floor.
