DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 251,491, dated December 27, 1881.

Application filed September 24, 1881. (Model.)

To all whom it may concern:

Be it known that I, GEORGE W. WINTERS, of Knoxville, in the county of Marion and State ot'lowa, have invented a certain new and useful Improvement in Door-Checks, of which the following is a specitieation.

This invention has relation to improvements in door-fastenings for use in houses, railroadcars, and vessels; and the object of my invention is to produce a device,which is simple and effective, for preventing a door from being thrown back against the wall, so as not to damage the plaster or paper by the key or knob of the lock, and to hold the door open, it' desired, so that it will not swing to and fro from the tects of currents ot' air or other causes.

My invention consists in attaching to the base-board, or upon the'tloor, a fixture holding a vibrating hook-latch, which has pivotal inclines for automatically returning to and retaining the desired position in the fixture by its own gravity and without the use ot' a spring, said latch having a stop at one end for limiting the swing ot the door and a curved hook at its opposite end, which will catch and hold the door, all as more full y hereinafter described and specically claimed.

In the accompanying drawings, Figure 1 represents a sectional plan view of a door with my check in position for holding` it open; Fig. 2, a cross-section of the door-check on line x a: in Fig. et; Fig. 3, a plan view; Fig. 4, a plan of the vibratable latch detached; Fig.5, a plan view of the bracket and lower socket-plate of the door-check, and Fig. 6 a plan view of the end of the bracket.

A Like letters represent corresponding parts in all the figures.

A denotes the vibrating latch. This is a curved bar with trunnions c a, projecting from both sides at about its middle, and having an oval hub, b, with longitudinal chamfered sides, so as to present sharp edges toward the ends of the trunnions. At one end this latch has a head, c, upon which is formed a rectangular shoulder with the central body of the latch, while its rear projecting end is rounded oft, and butts against the rear of the capplate for limiting the swing movement of the latch. The opposite end of this latch is formed with a hook, d, having a rounded or beveled face.

This latch A is secured between two plates, B and C. The plate B has cast a raised flange, e, toits front, and a step-bearing,f, to the middle thereof. This step-bearing has a socket for admitting either one of the trnnnions a of the latch, and has a prismatic groove in its upper face that is diametrical with the socket and longitudinal to said plate. The cap-plate C is cast to the upper edge'otl a vertical plate, g, having a flange, l1., to its base, which, being seated upon plate B, is secured thereto by a screw,o, t'our small lugs, t' i, on plate B serving to steady the plate C in its acquired position. The plate C has a hub,p, cast to its top, and from the under side of the plate a socket is drilled into this hub for receiving and holding the upper trunnion aI of the latch.

As will be noticed, the chamfered hub b of the latch A will ill the prismatic groove in step-bearingfof plate B when the latch is at rest and in line with the front edge ot' plate B but by swinging said latch the sharp edges of the hub will have to t'ollow the inclined sides ofthe groove in step-bearingf, whereby said latch is elevated,and as soon-as released the latch will regain its former position by its gravity. By this arrangement the use of a spring is obviated.

The plate B can be secured directly upon the floor by wood-screws. Where carpets are laid, or for other reasons it is not desirable to fasten the plate upon the tloor, the plate B is adjustably secured upon a bracket, D, which has a fla-nge, j, that is screwed against the baseboard of the room. For better strength and lightness I have thel bracket D chamfe'red out at the bottom. The plate Bris secured upon the end of bracket D by a screw, lc, and for adj nstably holding it in proper position a small stud or nipper, projecting from the under side of plate B, is to enter any one ot' a series of small notches, n, arranged o n a circle around screw-hole k. This fixture is secured to the door or base-board, so that the edge of the swinging door F will tirst come in contact with the end of the rounded face of latch-hook d, and will push said hook back, whereby the latch A will be somewhat turned and elevated, and after the door edge has passed said hook it will strike against the shoulder formed by head c, when the latch A will at once regain IOO its former position and the edge of the door will he locked between head c and hook d.

A small metal plate, s, Fig. 1, is let into'the edge of the door for the point of the hook to catch behind and to prevent its turning, so that the door, before being closed, will have to be released first by'pushing the hook back with the foot.

The trunnions c and hubs b ofthe latch are made alike on both sides for enabling` thelatch to be inserted between the plates either way for enabling' this door-check vto be applied to either right or left handed doors by simply reversing the latch at'ter removing the screw 0.

This device, as will be readily seen, is very simple and durable in its construction and reliable in its operation.

What I claim as my invention is- 1. The latch A, hMYing.,r head c, hook d, and trunnions a, with chamfered hubs b, secured between plate B,having socketed and grooved and by a nipple entering any one ot' a series of recesses, n, all substantially as and for the purpose set forth.

3. In a door-check, the combination of a vibrating latch adapted to receive and hold a door, a bracket adapted to be secured to the base-board, plate B, adj ustably secured to said bracket, and having lugs t' z', and plate C, having vertical plate g and flange h, saidlatch vibrating between said plates B and C, substantially as and for the purpose set forth.
