MARCUS LANE, OF FREEPORT, ILLINOIS.
SPRING-HINGE.
SPECIFICATION forming part of Letters Patent No. 625,77 9, dated May 30, 1899. Application filed .Tilly 29,1898. Serial No. 687,238. (No model.)
To all whom it may concern:
Be it known that I, MARCUS LANE, a citizen of the United States of America, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvementsin SpringHinges, of which the following is a specification.
My invention relates to a double-acting spring-hinge for holding a door, adapted to swing both inward and outward, normally closed; and it consists of certain new and useful features of construction and combinations of parts hereinafter fully described, and specifically pointed out in the claims.
Referring to the accompanying drawings,
which form a part of this specification, Figure lis a central vertical section of the hingecase and parts of the hinge. Fig. 2 is a top plan View of the hinge with its parts in position to hold a door closed. Fig. 3 is a like View of the same, showing the positions assumed by the parts thereof when the door is wide open. Fig. Il is a section at the dotted line 4: 4E in Fig. l of parts there shown.
Like letters of reference indicate corresponding parts throughout the several views.
A A' A2 are the base, sides, and top of the hinge-case. The base A has a short tubular bearing A3 sunk thereinto. The top A2 has a circular bearing A4, extending therethrough, which is prolonged by means of the tubular portion A5 integral therewith.
. B B are cylindrical studs projecting vertically upward from the bottom A of the hinge` case, whereto they are rigidly connected by being cast integral therewith or otherwise.
C is a rock-shaft verticallymounted in the bearings A3 A4 in the hinge-case and provided with lateral projections D D', supporting the Vertical pintles E E., the axes of the pintles and rock-shaft all being in the same vertical plane.
F F are peripherally grcoved pulleys mounted on opposite sides of the rock-shaft C on the pintles E E.
G G are bushings freely turning in the pulleys F F and upon the pintles E E.
Il Il are spiral springs engaging by their upper ends with the grooved peripheries-a preferable form only-of the pulleys F F and connected by their lower ends-in this instance intermediately'with the base A of the hinge-case.
I l are ratchet-keys for adjusting the ten- In use the hinge-case and all its contents,
as shown in Fig. l, are so placed .that the upper surface ofthe top A2 will be on a level with the 4upper surface of the under or rough floor. Thereafter the upper iioor is so laid as to cover the top A2, extending over to, around, and to the top of the tubular portion A5.
The hinge-plate J and shank A6 are set into a mortise in the lower end of the door (not shown) to be controlled by the spring-hinge.
I claim and desire to secure by Letters Patent- 1. In a spring-hinge, in combination, a vertically-mounted rock-shaft provided with lateral projections supporting two vertical pintles, two pulleys mounted, on opposite sides of the rock-shaft, on the vertical pintles and two spiral springs engaging, by their upper ends, with peripheries of the pulleys,and connected, by their lower ends, with the base of the hinge, substantially as and for the purpose speciied. i
2.' In a spring-hinge, in combination, a vertically-mounted rock-shaft provided with lateral projectionssupporting two vertical pin# tles-'-the4 axes of the pintles and the rock-shaft all being in the same vertical plane-two pulleys mounted, on opposite` sides of the rockshaft,on the vertical pintles,two spiral springs engaging, by their upper ends, with the peripheries of the pulleys, and connected, by their lower ends, with the base of the hinge, and the ratchet-keys for adjusting the tension of the spiral springs, substantially as and for the purpose specified. f.
