Application iled March 2, 1899. Renewed February l0, 1900. Serial No. 4,823. (No model.)

To @ZZ whom it may concern:

Be it known that I, WILLIAM GERWIEN, a citizen of the United States, residing at 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 a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates more especially to improvements in that class of spring-hinges that are termed double-acting and adapted for use in hanging doors that are capable of being opened in either direction from a common xed center.

The object is to 4provide a device of this character that is simple in its construction, possessing great durability, not liable to get out of order, and to retain the door and jamb in their proper relative position with but little liabilityof being affected by constant use or from other causes.

Figure l shows a door and hinge in their closed position. Fig. 2 shows the same in their open position. Fig. 3 is a vertical section through the door and jarnb on line 3, Fig. 5, looking in the direction indicated by the arrow. Fig. l is a horizontal plan section on line 4, Figs. 2 and 3. Fig. 5 is a itransverse section on linel 5, Fig. 3;, and Fig. 6 is a detached detail of construction.

A may represent the broken-away part of a door, and A' the corresponding jamb part, to which the respective leaves of the hinge are attached. The stationary hinge-leaf B is rigidly secured to the jamb and the companion stationary leaf B rigidly secured to the door. At their upper ends these companion hinge-leaves are connected by the intermediate movable hinge-plate B2 and at their lower ends by the movable hinge-plate B2, which is the usualarrangement. In the present invention, however, the hinge-plates B2 B3 are of a concave-convex shape, the object of which will be hereinafter described.

The jamb hinge-leaf B is provided between its respective ends with the cylindrical case B4, inclosing the torsion-spring O. The upper end of this spring-case is closed by a hub C and the lower end by a corresponding hub O2. vThe respective ends of the torsion-spring 'erative connection.

are secured in the companion hubs, as at ct, and when the door is opened in either direction the tension acts to automatically close` the same. A rod O2 passes longitudinally through the open space in the center of the tension-spring and has the companion hubs mounted on the respective ends thereof, which forms a common connection therebetween and serves to hold the same in exact alinement. The free ends of the rod O3stop short at a point just outside of the hubs and provide for the connection of the operatingiarms.

One end of an arm D is mounted on the upper end of the rod` O3. The connecting hinge-plate B2 is provided on the convex side and lower end with a boss a', to which is attached one end ofva common `link D by a pivot-pin ct2,'which is in the vertical center of the hinge-plate B2. The free end of this link is pivoted to the free end of the arm D, as at a2, Fig. 6, and forms the necessary op- The arm D is provided with a lug CL4, Fig. 6, through which is inserted a pin a5, adapted to engage with any one of a number of holesa, formed in the hub C', by which arrangement the tension of the torsion-spring is regulated and operative connection between said hub and the arm D is made.

The hinge-plate B2 vpivotally connects the door and jamb leaves at their upper ends. The pintle a7 forms the pivoted connection with the door hinge-leaf and the pintle aswith the jamb hinge-leaf. When the door is swung open in the direction shown in Fig. 2, the connecting hinge-plate B2 remains stationary against the j amb,as the door hinge-leaf swings on the pintle a7. There being no movement of the connecting hinge-plate, the hub C and the connecting-arm D and link D also remain stationary, the torsion-spring being twisted at the lower end. In this position the convex side b of the hinge-plate B2 is outward. When the door is swung in the opposite direction, the hinge-plate B2 follows the movement of the door and turns on the pintle as, which is on the opposite side of the door from that of the pintle a7, the hub C and its connecting` arm and link moving at the same time and twisting the spring from the upper end.

The construction and arrangement of the lower hinge connections are the same as the IOO e Genese i Corresponding upper parts and may be described as follows: One end of an arm D2 is mounted on the lower end of the hub connectinglrod C3. To the free end of this arm is pivotally connected one end of a link D3, the opposite end lof which, Fig. 4E, connects with a pivot-pin inserted in the boss b2, formed on the convex side and upper end of the connecting hinge-plate B3. In this opening movement of the door, Figs. 2 and 4, the lower hinge-plate B3 follows the movement of the door` and presents the concave side b3 outwardly, the boss b2 on the convex side filling into the recess b4 in the hinge-leaf B. Opening in the direction shown, the connecting hinge-plate B3 turns on the pintle b5, and opening in the opposite direction the hingeplate B3 remains stationary against the jamb, the hinge-leaf:` B' turning on the pintle bs.

The arrangement of the connecting hingeplates is such that they have an alternate action or movement, so that the relative position of the same is reversed in accordance with the direction in which the door is swung, the moving hinge-plate acting on the spring, storing up the power necessary in automatically closing the door. By having the connecting hinge-plates of a concavo-conveX shape it is possible to make the connecting arms and links the same length and the pivotal centers the same distance' apart, so that when the door is closed the joining ends of the connecting lever-arms and links are all in alinement with the hinge-knuckles and present the finished appearance of Ithe same, being mounted on the pintles connecting the hinges.

The hinge-leaves B B are provided on opposite sides, top and bottom, with lugs d cl2- that is, two on each side ofthe door, the tWo on the saine side being in a diagonal plane and having frictional contact with the knuckles (Z3 on the connecting hinge-plates B2 B3 and forming a stop or checkin preventing the door from swinging too freely back and forth when allowed to fly shut. These lugs will also or-` i dinarily prevent the doors from being opened by the action of the wind.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isL

1. In a spring-hinge, the combination of the companion hinge#leaves, the connecting hingeplates, of a concavo-convex shape, the tensionispring, the connecting-arms, and the connecting-links, said arms and links be'- ing of the same length, the links connecting with said hingeplates on a line through the vertical center thereof.

2. In a spring-hinge, the combination with a tension-spring, of acase, inclosing the same, the companion hubs, loosely inserted in the respective ends of said case, the rod connecting said hubs and havingy its free ends stop short outside thereof, the arms connecting with the projecting ends of said rod, the connecting-links, and the concave-convex hinge plates.

3. In a spring-hinge, the combination with the hinge-leaves, of the connecting concavoconvex hinge-plates, the links pivoted to 'said plates on a line through their vertical center, the arms, connecting with the free end ot' the links, the rod, on which the opposite ends of said arms are mounted, the tension hubs mounted on the respective ends of said rod, the case wherein are seated the reduced ends of said hubs and the tension-spring, inclosed therein having its respective ends secured in the tension-hubs.

4. In a spring-hinge, the door and jamb leaves provided on opposite sides with projecting lugs adapted to check any unnecessary swaying of the door. l

In testimony whereof I afX my signature in presence of two witnesses.

WILLIAM GERWIEN.
