Description

UNITED STATEs PATENT GFFICE.
LORENZVBOMMER, OF BROOKLYN, NEW YORK.
IMPROVEMENT IN SPRING-HINGES.
Specification forming part of Letters Patent No. 184,058, dated November 7, 1876; application led October 14, 1876.
To all whom it may concern: A
Be it known that I, LORENZ BOMMER, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Spring `Butt-Hinge, of which the following is a specification:
In the accompanying drawing, Figure l represents afrontelevation ot' my improved spring butt-hinge, partly in section; Fig.2, a horizontal sectionot' the same on line x x, Fig'. l; and Figs. 3 and 4 are, respectively, side and top views of Ithe upper and lower pintle-sockets.
Similar letters of reference indicate corresponding parts.
The object ot' my invention is to Ifurnish an improved spring butt-hinge which closes the door in an easy and noiseless manner, producing reduced friction on the faces ot' the seats, and being cheap, strong, and effective.
The invention consists in the construction and arrangement of parts which will be hereinafter' more fully described, and then pointed out in the claims.
In the drawing, A are the ilanges or Wings of a butt-hinge, which are connected by a center pintle, B, passing through perforations of the seats B of the flanges, and being riveted to the end buttons Al at the top and bottom of the hinge. The buttons A are not made detachable, to be separately' applied to the hinge-seats, but cast in one piece with the seats of the swinging flange A applied to the door. This dispenses with the separate casting, finishing, and attaching of the buttons, and imparts, by the greater bearingsurface on the pintle, a more rigid connection with less friction on the faces or bearings of the seats. The hinge is provided with an interior spiral spring, C, that is secured at one end into a slot or recess, a, of a socket, b, cast with the lower seat B of the flange A, attached stationary to the door-casing. The upper end of spiral spring O is secured to a similar recess, a', of a detachable pintle-socket, b, which turns on the pintle during the opening and closing of the door. The tension ot' the spring C is adjusted in the customary manner by introducing'a small rod into one ot the radial holes ot the movable socket b', and turning the same, inserting a small pin into the hole nearest to a raised part of the swinging doorflange. The iiange of the door bears then, in opening, against the pin, twisting thereby the spring, and closes the door `by the reaction of the same. The spiral spring C is inclosed by a cylindrical sleeve, D, that is accurately ltted to annular recesses b2 of the movable pintlesocket bl and ot' the fixed socket b of the seat of the stationary flange A. The sleeve D is open at the side and provided with side ilanges d that extend into recesses at both sides of the stationary flange being riveted ilush with the same. The sleeve D serves to strengthen the flanges A, secures the position ot' the movable socket b', and incloses and keeps out the dust from the interior ot' the hinge.
The spring butt-hinge ot' this construction is cheaper, stronger, and less liable to friction and sagging of the door than similar butthinges heretofore patented.
The butt-hinge may be applied to any side 4
