Specification forming part of Letters Patent No. 167;,900, dated-September 21,1875japplication filed -v August 6, 1875. p

To alt whom it may concern.-

Be it known that I, GARRETT Z. HOUSE, of the city, county, and State of New York, have invented certain new and useful Improvements in Combination Spring-Hinges, which are set forth in the following specification, reference being had to the accompanying drawings, which form a part thereof.

The object of my invention is to construct a cheap and practical hinge or butt that will swing a door both ways through the jambs or casings, and hold it closed when at rest, at the samer time swing on each alternate corner of the casing, and attach itself firmly to the same at every point of its swing, thus preventing danger of any settling or sagging.

The rst part of my invention consists of a double-acting spring-hinge or butt formed of two outer plates or leaves and a sectional center-plate, divided diagonally, withV springs connecting the rst or main plate on each edge with one end of the sectional centerplates, the other end of the center-plates beiEng hinged to the third plate, as shown in The center sectional plate is divided diagonally, as shown in Fig. l, B B, thus forming an extended spring-joint on both sides, and attaching the same to the first or main plate by springs in knuckles E E. Both of the mainsprings of the hinge are attached to the same or main plate, and act directly and conjointly in holding it within the jamb in a direct line, thus ai'ording a combined supporting power of the two springs, and preventing the door from settling or sagging.

I thus relieve the strain upon the screws and casing, and hold the door in its place, when at rest, by the joint action of the springs, acting on both sides alike. I also obtain a large space in which to use the springs.

The knuckles' forming the hinge connecting these plates receive the tubular pintles in which are placed the compound or combination springs. These knuckles should be exten ded on each side beyond the plates to the dis'- tance required to give strength to the springs.

The second part of my invention consists of the combination of torsion and spiral spring,

constructed vand made tol operate within the tubular pintles, as shown in Fig. 5, and these combined springs are applicable to double or single spring-hinges. The torsion-spring I construct of two o more leaves ofthin flattened steel, like a clockspring, fastened together, and made to act within the spiral spring, the two springs being' Apassing completely through the spiral spring,

the outer end is attached to the ratchet-nib, as shown in Fig. 5. .Ihe outer end of the spiral spring is connected by a small hook to the tubular pintle, which is connected to the sectional center-plates, and by them to the third plate, and the torsion-spring being attached by the ratchet nib to the first plate, the two springs thus act together, and form a compound or combination spring, acting Within the tubular pintle in the manner above described and shown by drawings.

My combination or compound spring, thus formed, possesses the force and elasticity of the two springs combined and acting within each other. I thus utilize my space and get double power.

This spring may be applied to all butts and hinges, both single and double acting. They may be removed for examination or repair by unscrewing the ratchet-nib on the outer end and withdrawing it, without disturbing the action of the door.

It shows the door fully open, exposing the tWo sectional centerplates B B and parts of the first plate A and third plate C, the springs D D, and hingeknuckles E E, connecting With third plate O.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters` Patent, s-

1. The combination and arrangement of the diagonal center-platesB B, giving an increased length of springs, and acting, by the compound or combination springs D D, on first plate A, and, by hinge knuckles or connectionsGG, on third plate C, forming a-hinge held at every l GARRETT Z.
