THOMAS L. MORGAN, OF NEW UASTLE, PENNSYLVANIA.
To all whom it may concern Be it known that I, THOMAS L. MORGAN,
citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Door- Checks, of which the following is a specification.
This invention relates to door "checks of that type employing a' sliding bolt carried by the door and adapted to be advanced to contact with the floor or otherwise for the purpose of holding the door in any desired position. 7
The object of the invention is to provide an improved device of the kind, suitable for use on a door in various positions, and capable of easy and convenient manipulation for the intended purpose. The advantages will be more fully apparent from the following description and the accompanying drawmgs. :5 .7
In the-drawings: Figure 1 is a: perspective view showing the device mortised' into the edge of a door,Fig. 2 is a similar view showing'the device applied to theside of adoor. Fig. 3 is a front elevation of the device. Fig. 4 is a rear elevation. Fig. 5 is a side elevation. F ig. 6 is a longitudinal section. Fig. 7 is a detail of a mortise-plate which may be used when the device is set into the side of a door. Figs. 8, 9, and 10 are perspective views of an'op'erating plunger and finger piece connected thereto.
In the drawings, 6 indicates a door. The casing of the check may set into the mortise in the door as shown in Fig. 1, or it may be reversed and set against the outside of the door as shown in Fig.2. The casing includes a plate 7 having holes for the attaching screws 8. This plate is fiat on one side. On the opposite side it has a cylindrical tube or barrel 9 open at both ends, and with a shoulder 10 at the bottom to support a spring 11 coiled around a foot bolt 12 which may have a rubber tip 13 and which works through the opening at the lower end of the barrel. The upper end of the spring presses under a head 14 at the top of the bolt, and
the spring tends to lift the bolt. Another spring 15 is confined in the barrel between the head of the bolt 12 and a plunger 16 which works in the upper end of the barrel, when the plunger is pressed down the foot bolt is forced out against the floor, with a pressure depending on the compression 0t Specification of Letters Patent.

the spring 15, which may be varied by more or less pressure on the plunger 16. Said plunger is operated by means of a finger piece 17 the innerend of which fits in a cross hole in the upper end ofthe plunger, where it may be fastened by a pin 18. The finger piece is cut away on opposite sides to form an inclined catch or dog portion 19. The front plate 7, as well as the barrel 9, has a central longitudinal slot the edges of which are notched on both sides as indicated at 21 and 22, and at the upper end the slot in the front plate branches into two upwardly and outwardly inclined or curved slots 23 exbe given a quarter turn in any one of three optional arrangements.
When used in the edge of a door, as shown in Fig. 1, 1t 1s sometimes desirable to have the finger piece turn one way and sometimes the other way, according to the way the door closes, and, therefore, two slots 23 are pro- -vided. The door is recessed at each side of the mortise containing the casing, and a small socket piece 25 is set 1n each recess,
and held by a screw 26, to give a ood finish. In this use the finger piece may to swing either way, to catch in either set of notches 21. The finger piece may be removed from the plunger and set either way, so that its inclined edge will be presented toward one or the other set of notches. Thus Fig. 8 shows the finger piece set one way and Fig. 9 shows it set the other way, and the curvature of the branch slots 23 permits the finger piece to be swung one way or the other accordingly. The sockets 25 are sufficiently deep to permit the finger piece to be swung around to position flush with the edge of the door, so as to not obstruct closing the door.
In the operation of the device, with such arrangement, the finger piece, when in raised position rests in one of the sockets. To advance the bolt the finger piece is pressed down and swung around in one of the slots 28 into the longitudinal slot, and then pressed down to advance the bolt to contact with the floor, compressing the spring 15 to the desired extent, and the edge of the part 19 of the finger piece is engaged in one of the notches 21 en one side at the be arranged tending to the end of the plate. The slot in slot, thereby holding the bolt pressed against the floor. To release the bolt, the finger piece is detached from the notch and released, and the spring lifts the plunger, the'finger piece lifting into the branch slot 23,-the curvature of which swings the finger piece around to original position, permitting the door to be closed. The finger piece is long enough to project at its end slightly beyond the corner of the door so that it may be easily grasped and operated. A similar operation takes place when the finger piece is reversed on a door closing the other way.
For use on the side of a door, as shown in Fig. 2, the finger piece is engaged with the plunger through the slot in the barrel, and when depressed is caught in one of the notches '22, and when lifted by the spring swings around in the slot 24 toward the side ofv.the' door,as shown in Fig. :2.
In either arrangement, when the plunger l6 is lifted by the spring 15, the bolt 12 is lifted by the spring 11, the pressure of the spring 15'being then released by its extension to its full length. 7
Instead of being placed on the side of the door in reversedposition, as shown in Fig. 2,
' the device may be mortised into the. side of the door similar to themanner in which it is mortised into the edge of the door as shown in Fig, 1, and, in such position, a socket piece 25? is set in a recess in the side of the door, to receive the finger piece, this socket being somewhat longer than the finger piece so that apersons finger may be inserted to pick out the finger piece and 'to depress the same.
o- The constructionprovides a device which may be applied to a door in various positions, according tol'ocal conditions, or the wishes of a builder, and which is capable of operation in any-position. By reversing the of, a plunger slidable in the casin a bolt b operated by the plunger, and an operating device connected to the plunger and adapted to project through either of the slots.
2. In a door check, the combination of a casing having a slot in opposite sides thereof, the casing being reversible to attach either side there0f to a door, a bolt in the casing, and an operating plunger for the I bolt, provided with a handle interchangeable to project through either slot.
3. In a door check, the combination of a casing having a longitudinal slot provided with notches at the opposite sides thereof and terminating in two opposite curved branch slots, a bolt working in the casing,
a plunger in the casing behind the bolt and adapted to advance the latter, and a han- -dle extending through the slot and having a beveled catch part, the handle being attached to the plunger and adjustable to engage the catch part with either set of notches and adapted to enter either of the branch slots and swing laterally therein.
In testimony whereof, I do afiix my signature in presence of two witnesses.
