SPRING-HINGE.

SPECIFICTIONformng part of Letters Patent No. 291,169, dated January 1, 1884.

' Application filed September 1S, 1893. (Model.)

l'b'aZ 7,071,077@ it may concern.- Be itvknown that I, WALTER DUNCAN, Aa citizen of theUnited States, and a residentof 1 Chicago, in the .county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Hinges; and I do hereby declare the following to be afull, clear, 4and exact description of the same, reference vbeing had to the accompanying drawings, formroing a part of this specification.

My invention vrelates to improvements in that class of double-acting spring-hinges which are so constructed f as to permit of the opening in either direction of the door or gate to '1 5 which they are applied; and my improvements,

have for their objects, mainly, to provide animproved arrangement of parts whereby the tension of the coiled hinge-springs can be conven- 4iently and effectively changed and adj usted to 2o suit the difference in weight or size of the door or gate to which they are applied, 'and also to ,furnish means whereby the alignment of the lhinge parts can be readily adjusted, in order j, `to bring the door as it closes to the proper I attain such objects by the construction and arrangement of rparts illustrated in the accompanying drawings, in whichv Y Figure l is a perspective view of my improved hinge complete. Fig. 2is an elevation partly in section ofthe same. Fig. 3 is a horizontal section at line x m. Fig. 4 is a bottom plan of the upper fixed plate or eye of the hinge. Fig. 5 is a perspective view of the 3 5 tubular upper pintle of the hinge.' Fig. Gis a horizontal section at line x x. Fig. 7 is a perspective view of the lower pintle of thev hinge and its washer for receiving the lower end of the spring. Fig. 8 is a top plan of the 4o lower fixed plate or eye of the hinge.

Similar letters of reference indicate like parts in the several views.

In the accompanying drawings I illustrate my improvements applied to that form of double-acting hinges in which a single axiallyarranged coiled spring is employed to close the hinge, the arrangement being such that the opening of the door in one direction will contract or compress the upper portion of the 5o spring, and the opening of the door in the other direction will contract the lower portion of the spring, the lower end of the spring in the one case remaining stationary and the upper end in other case.

Referring to the drawings, A represents the upper, and B the lower stationary leaf or eye of the hinge that is secured to the jamb of the door.

C is the movable leaf of the hinge, having suitable plate portion for attach-ment to the 6o door or gate, and provided with pivot-eyes C C2, and a hollowed portion, C3, for receiving and housing the coiled spring D. The pintle Aor spindle by which the upper fixed eye or plate, A, and the pivoteye C of the movable 65 plate C are hinged together consists of a tubular spindle, E, having a projecting lug or spline, e, confined within a curved recess, a;

in the eye A.. AXially within this tubular spindle E is arranged a cylindrical stem, F, hav- 7o ing at its lowerv end a head, f, for the attachment of the upper end of the coiled spring D, andat its upper end a cap or casing, F', surrounding the enlarged head E of the tubu-lar spindle E, as clearly indicated in Fig. 2. The cap F is provided with a series of radial holes or slots, f, by means of which it is turned to adjust the tension of the spring D, and a-series of holes, f2, in line with a series of radial holes, c', in the enlarged head E', so that the 8o two portions E F can be locked to the required adjustment by a locking pin or screw, f3, pass ing into one of the series of holes. rIhe purpose of the curved recess a is to permit of a free movement of the lug c in a movement of the hinge member C to the right, and to hold it stationary in the movement of said member t0 the left by the lug e coming in contact with the projecting face c.

a2 is a hole or opening into the recess a, to 9o permit of the introduction of a rod or pin to engage the lug e and hold the tubular spindle E stationary while the tension of the spring is being adjusted.

a is a radial slot through the eye part A595 into the recess c, for the downward passage of the lug e in putting the hinge together.

Gis the pintle or spindle by means of which the lower hinge or pivot-eye, C2, of the member C, and pivot-eye ofthe fixed-hinge member B, Ion

are journaled together. This spindle is held from rotating` in the lower member by having its end squared, as shown, or by means of a set-screw, or by being rigidly keyed therein, as desired or found most convenient.

H is a collar arranged loosely around the upper end of the pintle G, and having suitable provision for the attachment of the lower end ofthe coiled spring D, as shown in Fig. 2. On the under side of this collar is formed stoplugs L h', engaging respectively against the abutment, face, or offset e of the movable member C, and the stop-lug or spline r/ of the pintle G, the arrangement being such that a movement of the collar is permitted when the hinge-member is moved to the left, with a consequent eompression or contraction of thelower portion ofthe spring, a movement of said collar to the right being` prevented by its lug l1. coming in Contact with the lng or splinef/ upon the fixed pintle G. (See Figs. 6 and 7.) \Vith the construction of parts as above described, the movement to contract or compress the spring will be from the top, in moving the door-plate of the hinge tothe right, the lower end of the spring being held stationary, and from the bottom in moving the door-plate of the hinge to the left, the upper end of the spring in this case being held stationary. rIhe holding of the lower end of the spring in moving the hinge-plate C tothe right is effected by the lug h of the collar H, to which the lower end ofthe spring is attached, abutting against the stop-lug g ofthe fixed pintle G, while the holding ofthe upper end of the spring in moving the hinge-plate C to the left is effected by the lug or spline e of the upper spindle, E F, to which the upper end of the spring is attached, abutting against the affixed abutmentface a of the Iixed member A.

Heretofore great diiiieulty and ineonven ience have been met with in not having the door to close properly in its frame. rIhis is initially duc to imperfect or uneven setting of the hinge and subsequently by wear of the parts. To overcome these difiiculties and compensate for any irregularities that may occur in the manufacture of the hinge, I provide the abutmentfaces c c', against which the lug e, or a continuat-ion thereof, and the lug l1y of the collar H usually abut, with set-screws I, the points of which will then form the abutments, which can be so adjusted as to take up all lost motion and thereby cause the door to come to a stop in propel.' position within its frame.

-1 p earner Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is*

l. In a spring-hinge of the class described, the hinge-pintle provided with a` stop lng or spline, in combination with the movable member provided with an adjustable abutmentscrew, as described, and for the purpose set forth.

2. In a spring-hinge of the class described, the combination of the movable and fixed members with a pintle or spindle composed of a tubular portion, Il, provided with a stop-lug, c, and a stem portion, F, connected to the operating-spring, with means for adjusting the parts E F in relation to each other, substantiall r as described, and for the purpose set forth.

3. In a spring-hinge of the class described, the combination of the collar H, having lugs h h, stationary pintle G, having stop-lugg, and movable member G, having abutment-offset c', as described, and for the purpose set forth.

5. In a spring-hinge having its pintle formed of atubular stem, E,having a limited movement in the fixed eye of the hinge, and a stem, F, attached to the spring, and adjustably secured to the stem E by a series of radial slots, dft, and locking-pinf, substantially as described, and for the purpose set forth.

6. In a spring-hinge of the form described, the fixed eye A, provided with a hole or opening, ai, comn'lunicating with the curved recess a, as described, and for the purpose set forth.
