IMPROVEMENT IN SAFETY-PINS FOR THlLL-COUPLINGS.
Specification forming part of Letters Patent No. 148,421, dated March 10, 1874; application filed January 20, 1874.
To all whom it may concern:
Be it known that I, JosEPH G. DANCE, of Long Green, in the county of Baltimore and State of Maryland, have invented a new and Improved Safety-Pin for Thill-Couplin gs and jolting or ordinary casualty will displace it.
The invention consists in providing the coupling pin or bolt with a notch near its point, and combining therewith a slotted or apertured plate, which is hinged to a spring attached to the head of the pin or bolt, as herein fully described.
A represents a pin, whose head a is preferably in one piece with a spring, B, to whose end is pivoted a plate, 0, having the aperture with edge 0. The bolt A tapers to" Ward the point, near which is a notch, whose shoulder a is perpendicular to the axis of pin. The swinging plate 0 receives the point of pin, and, being pressed up, causes the spring B to yield until the notch is reached, when the spring draws into the notch the eye 0, which is then held firmly against the shoulder a.
This lock-pin is applied quickly and with great facility, while the spring-held plate 0 eflectually guards against its detachment by any ordinary cause.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
I11 combination with the pin A, having the notch near its point, the apertured plate 0 and spring B, the plate being hinged to the free end of the spring, as shown and described.
JOSEPH e. DANCE.
