COMBINED DOOR CHECK AND CLOSER.

Specification of Letters Patent.

Patented J an. 26, 1915.

Application led January 2, 1914. Serial No. 809,975.

To all whom t may concern Be it known that I, GEORGE citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Combined Door Checks and Closers, of which the following is a specification.

This invention relates generally to builders hardware and particularly to that type of door hinges described and claimed in Letters Patent of the United States granted to me on the 26th of July, 1910, No. 965,265.

This `invention is an improvement over `that described in my application Ser. No.

602,261, allowed March 24, 1911.

The novel and useful features of the present invention will be hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- 4 igure 1 is a side elevation of one hinge applied; Fig. 2 is an elevation of the butt member detached; Fig. 3 is a transverse section on the line 3-8 of Fig. 1; Fig. 4 is a vertical section; Fig. 5 is an elevation of the lap member; Fig. 6 is a view of the lower end of the butt member; Figs. 7 and 8 are views of detached details, and Fig. 9 is a transverse section on the line 9-9 of Fig. 4 with the spring omitted.

Throughout the following description and on the several figures of t-he drawings, similar parts are referred to by like reference characters.

Referring to the drawings for a specific description of the mechanism, 10 indicates a door or any other part of like nature adapted to swing laterally in either direction on a vertical axis determined by any desired number of hinges 11, by which the door may be secured to the stile 12. The hinge comprises two main parts,the lap member 13 and the butt member 14, secured rigidly to the door and the stile. These parts are maintained in normal operative connection by a pair of plungers 15 and 16, which break joints with the alined tubular portions of the butt and lap members. plunger 15 may be withdrawn from the H. WHITE, a

butt by loosening and lifting upon a screw 15, in order to separate the butt and lap, and the plunger 16 may be withdrawn from the butt into the lower part of the lap by bearing down upon a screw 16', against the tension of the buffer spring 17.

To close the door automatically after the same has been opened in either direction I provide within the butt a strong coil spring 18 connected to a pair of blocks 19 and 20. Within the end of said spring adjacent the blocks are projections or studs 18a, set into the respective blocks and each surrounded by a sleeve 18b having a lip 18C through which the end of the spring passes securing the sleeve against rotation on the projection 18a. These projections and sleeves keep the spring from buckling and bearing against the inner wall of the butt member. The block 19 has a square pintle 19 eX- tending upwardly through and fitted into a square hole in a finger plate or actuator 21, the upper portion of the pintle 19 being round at 19 and terminating in a fiat end 19a, which upon being grasped by a pair of pliers the block 19 may be forced downward so as to bring the round part 19 into the square actuator hole, permitting the block 19 to be turned in either direction to determine the proper or desired tension of the main spring 18, after which the portion 19 will again engage the actuator to maintain the said tension of the spring and the coperation between the actuator and the block. The block 20 likewise has a pintle 20 cooperating with the square hole in the actuator 22. The extremity of the pintle 20 is seated loosely in a rider or block 23 rigidly secured as by a screw 20 in the lower part of the butt. Each actuator has a nger 24 coperating normally with a lug or shoulder 25 formed in or on the face of the lap. Each linger' 24 also bears against the shoulder' 24 at the end of a slot 26 in the butt. These parts are arranged oppositely in pairs. When the door is swung open in either direction one finger bears against its shoulder 25, and the spring is put under tension thereby, the other actuator finger at such time being held against its butt shoulder 24;. Anti-friction rollers or balls 27 are shown between the bearing surfaces of the butt and lap, and in some instances it may be found advantageous to employ removable keys at 212L to secure the actuators rigidly to the block pintles.

An important feature of this invention consists in combining with and within `the hinge buffer means to control movement of the door and to provide a means to hold the door against undesired open swinging. This controller or buffer comprises the spring 17 supporting the plunger 1G and resting upon a seat 28. Said seat maybe provided on its upper surface with a lug 28 to center the spring 17, and is adjustable up or down within the lap to vary the tension of the buffer spring, by means of a threaded lug 28 upon which operates a nut 2S, and to which access may be had through a slot 28". The nut 28 is supported upon afiXed abutment 29, and the seat 28 is pre vented from rotation by a feather 28C eX- tending into the body of the lap. See Fig. 9. The plunger 1 6 on its upper end has a lug or projection 16 which coperates with a cam Q8 on the lower end of the rider 23, and is normally seated in the socket Q3 of said cam, preventing the door from freely oscillating or swinging on its hinges. vWhen the door is closing under the force of the main spring 18 it will be checked as it approaches its closed position, by contact of the lug 16 and the cam 23', the effect of such action being determined by adjustment of the spring. 17. A plurality of projections y16 and cams 23, may be employed if desired. The plunger 16 includes a thimble 16a which breaks joints with the butt and lap and within which thimble the buffer portion 1Gb of the plunger is free to slide vertically. The screw 16 normally secures the lthimble 16 from movement.

The several parts of the device may be made of any suitable materials or relative sizes, and the details of construction may be varied to a considerable extent without de arting from the spirit of the invention.
