DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 251,732, dated January 3, 1882. l Appiicanon ined August 23, Iseo. (Model.)

' lowing is a full, clear, and exact description thereof', reference beinghad to the accompanying drawings, and 'to the letters of reference marked tlIereon,\vlIich form a part ot'this speciteation.

This invention relates to door-cl1ecks; and itconsists in the several novel features of construction hereinaiter set forth, and pointed out inthe claims.

The door-check herein described and claim ed operates not only to check the door slightly' open, as is common with door-checks, but it may also be made at will to hold the door from closing, and is adapted to fasten the door closed.

In the accompanying drawings', Figure l is'` a perspective view ot' thecheck as it appears when the door is closed and when used to'fast en the door in this position. Fig. 2 is a perspective view of the door open to the length of the eheck-link. Fig. 3 shows the check-link pendent on the door-frame. Fig. 4 is a central horizontal section ot' the complete device in the position shown in Fig. 1. Fig. 5 is a central horizontal section of the parts applied to the door, and ot the outer end of the link when the door is ajar and is held from movement in either direction. Figs.4 6, 7, 8, 9, and l0 are detail views.

A is the door, and B is the door-frame.

C is a metal casing, about half an inch deep, containing the mechanism permanently applied to the door.

C is a boss applied to the frame B, hush with the case C, and having the check-link L,

y pivoted thereto by means of a hook, E', on the `boss and eye e on the link. Thelink L is slotted at S, and engages the door by means of aturnpin, T, secured to the door by means of the case C. An especially novel feature inthe turnpin T is that it may he slid backward and forward to and from the edge of the door in the slot'D of the case C with a movement over the corner or front edge of the case C, so as to serve, when at the door-edge, as a T, by which to hold the cheek-link and arrest the door, and tv hen slid inward away from the door-edge to serve as a turnfpin fastening, adapted to hold the check-link against the case C, and thus secure the door closed. To these ends said turn-pin is of peculiar construction, which will be pres ently explained.`

I is a horizontally-sliding catch, held loosely in place on the door by the case C, beneath which it is centrally placed. Its inner and exposed end is upturned to afford hold for the thumb and 4Iinger for the purpose ot' Working it, as seen clearly` in Figs. 2, 4, and 5, and its throw is limited by the screwj, which passes through the slot i in the slide. Said slide is intended to engage with the notch N in the link L when the door is opened the length of the check-link, and operates to hold the door `from closing. The notch N is clearly shown in Figs. 3,4, and 5, and in the last figure mentioned the slide l is engaged with said notch, as described. The slide I also serves' as a bottom plate, on which the turn-pin T runs, and ithas arib, r, on its outer face, which tits in a groove, g, on the under face of the turn-pin, which rib, so far as it extends in the movement of the turn-pin, holds the latter from rotation. The turn-pin T consists of the external thumb-head, the standard or shank t2, the lateral arms t, and the rear projection, t. The slot D of the case C, in which the shank t2 runs, extends down the front face of the case, as shown in Fig. 10, so that the turn-pin may tilt into the position shown in Figs. 2 and 5. When it so tilts the projection t protrudes from the slot D, as shown in said figures, and by such protrnsion holds the turn-pin from rotation at this point. rotation until moved to the rear of the slot D, where it is clear of the rib, and may turn in order to be released from the check-link L. If, however, it is desired to lock the turnpin at this point to prevent its turning(as when the turn-pin is used to hold the link L as a Jfasten- The rib r similarly holds it from ing of the closed door,) it can be so locked by 9 pushing in the slide I, so that the lugs b b, cast on the slide, pass one to each side ot' the rear projection, t', of the turn-pin and prevent its rotation. The link L is provided With a projecting corner, a, which, when the linkis thrown IOC off the turn-pin and falls pendent from the hook El, sets up under said hook and prevents the link from swinging outward in the way of the door.

The boss C is of peculiar construction. It consists of the hollow rising part, tapering toward the top, and the cap-plate o. The hook E is cast as an extension on the inner wall of the boss, and, as it overhangs the aperture of the shell, draws readily from the sand. The

cap a at its inner edge sets up against the hook E', and has a small flange, c2, on its under face, which drops close inside the outer wall ofthe boss', as seen in Fig. 4. The link being tirst ap plied to the hook E', the cap c is inserted be-` neath the hook. The parts are then fastened to the door-frame by screws passing inward through the cap c', as shown, and all the parts v are thus held permanently in place on the door' frame.

It has been found that by reason of the lnold- Ying usually present on the frames of doors itv is necessary to pivot the lilik to a raised part or boss, and to correspondingly elevate the T'fastening on the door. When this is done a stationary T-piece to engage the link projects so far as to be seriously in the way. This fault; is remedied in the construction herein shown,

'wherein the turn-pin is at the edge of the door thus engaged, inwardly from and outwardly to the edge of the door, so as to co-operate with the bar Lto cheek the door when fijar, and to form therewith a fastening to the closed door, substantially as described.

2. In combination with arigid check link or bar, L, having a notch or shoulder, N, and a suitable catch, T, ou the door, arranged to engage witli said link or bar to check the door ajar, the sliding latch I, adapted to be engaged at will with the shoulder N ofthe link L, so as to hold the door from closing, substantially as described.

3. In combination with the slotted link or bar L, the turn-pin T, secured inovably to the door by means which permit the turn-pin to slide inward from and outward to the edge of the door, and to rotate to receive or release the link only when receded, substantially as described.

4. In adoor-check, the slotted link L, pivoted to the boss C on the door-frame, the case C, having the slot D, the turn-pin T, having projections t and t and the groove g, and the bottom plate, I, provided with the rib r, combined and operating substantially as described.

5. In combination, the slotted link L, pivoted to the door-frame, the retaining-case G on the door, the rotating turn-pin T, held by the case C, and slide I, having the lugs b b, whereby the turn-pin may be secured from rotation when operating with the link L asa fastening for the closed door, substantially as described.

6. The link L pivoted to the door-frame by the hooky E and eye e, and constructed with the corner-projectionsa,which bear against the hook E to prevent the link from swinging in the way of the door, substantially as described.

In testimony that I claim the foregoingas my invention I aftx my signature in presence of two witnesses.

FRANCIS V. PHILLIPS.
