STEPHEN JOYCE, OF NEW YORK, N. Y.
Specification forming part of Letters :Patent No. 1l Q dated September 16, 1873; applicationr filed August 14, 1873.
To all whom it may concern:
Be it known that I, STEPHEN JOYCE, of the city, county, and State of NewYork, have invented a new and useful Improvement in Spring Butt-Hinges, of which the following is a specification:
My invention is an improvement in the class ot' hinges specially adapted for lise on doors which swing in either direction and are seli closing; and it consists in the construction and arrangement, as hereinafter described, of a tubular pintle provided with heads or plugs connected by a spring, and having a series of holes to adapt them to receive stop-screws for regulating the tension of said spring, and the pintle being inclcsed by sleeves having radial wings which forinthe leaves of the hinge, all as hereinafter described.v
In the drawing, Figure l, is a longitudinal section of the tubular nintle and surronndin g bands, showing the heads and spiral spring. Fig. 2 is a horizontal section of Fig. 1 taken on the line y y. Fig, Bris a horizontal section of Fig. l on the line z z. Fig. 4 is a horizontal section of Fig. l on the line z z.
Similar letters or' reference indicate corresponding ports.
A is the tubular pintle having a transverse slot, B, at each end, which ents the pintle about one-third of its circumference, and is snfiiciently 'broad to admit the stop pins or screws C U. D D are the heads, a portion, E7 of which enters the pintle and receives the step screws or pins U U. `'These heads are connected together by the spiral spring F, as rlhe interior portions oi' the heads have a series of holes which allow the stop-screws to be adjusted to stop the swing of. the door at7 the desired point. The
holes ,il in the enter Iportion of the heads are vided with a leaf, K, which enters the casing.' or door, and is fastened by means lof-screwsl through the holes L. The stop-pins C G strike these leaves when the door is swung, one be ing on one side and the other on 'the other side, as indicated in the drawing, the lower one being seen in' dotted lines. M is the central band, which is fastened to the pintlo by the screw N. 0 is the leef ofthe central band, which is fastened 'to 'the door or casing by means of screws in the holes i3. These leaves go into niortises in the middle 0i' the easing and door, and the latter is allowed to open in either direction so as to make at least a full opening, and when the hinge is thus attached suttieient tension is given the spring to close the door when swinging from either direction. The swing and closing of the door are regulated hy means of, the screw N, which is adjusted to .the proper one of' the series of holes (.2, as seen in Fig. 4.
Having thus described myinvention, I claim as new and desire to secure by Letters-Patent A spring butthinge, composed of the tubular pi'ntle A, hcads D D, spring F, stop-screws C l), and bands or sleeves I, J, and M, with the leaves K, K, and 0 and screw N, constructed and arranged as shown and described.
