SPECIFICATION forming part of Letters Patent No. 613,356, dated November 1, 1898.

Application filed December 15, 1897. Serial No. 662,062. (No model.)

To all whom it' may concer-n:

Be it known that I, OLIVER C. CONERLY, residing at lVanamaker, in the county of Horry and State of South Carolina, have invented a new and useful Door-Stop', of which the following is a specification.

This invention relates to improvements in door-stops; and the object of the same is to provide a device which is simple in construction and neat in appearance, which may be attached to any door, and by means of which the door maybe openedL as far as desired and retained in that position.

Vith the above object in view the invention consists of a casing secured to the door at the lower edge thereof, a plunger movable vertically through said casing and having iieXible plates secured thereto which engage the iioor, said plunger being provided with a ratchet on one side and held normally out of engagement with the floor, a spring-held'bolt adapted to engage the ratchet of said plunger and hold the latter in engagement with the iloor, and a vertically-movable wedgeshaped rod engaging a slot in the bolt and adapted by downward movement to disengage said bolt from the ratchet of the plunger, said rod being normally held raised by a spring.

The invention further consists in the improved construction, arrangement, and combination of parts, hereinafter fully described, and afterward specifically pointed out in the claims.

In order to enable others skilled in the art to which my invention most nearly appertains to make and use the same, Iwill nowproceed to describe its construction and operation, having reference to the accompanying drawings, forming part of this specification, in t which- Figure l is a perspective View of a door, Fig

by means of which it is attached to the door, screws C passing through the portion B and entering the door, as illustrated in Fig. 2. Movable vertically through this casing is a plunger D, having a ratchet E formed on one side thereof and carrying a plate F at its lower end and screw-threaded at its upper end to receive the screw-threaded cap G. Secured to the under side of plate F are the flexible plates H, which may be of rubber or any other desired material, for engaging the carpet or the floor. A spring Iis coiled about the upper projected end of the plunger, the lower end thereof resting upon the upper wall of the casing and the upper end bearing against the screw-threaded cap, by means of which the tension of the spring is varied.

Movable longitudinally in the casing is a bolt M, having upon its forward end the inclined engaging surface N, which engages the ratchet E of the plunger. This bolt has also a vertical slot O formed therein intermediate its ends, and has its opposite end reduced, as indicated at P, and formed with the shoulder Q. A spring R is coiled about said reduced portion and bears at its inner end against the collar Q and at its outer end against the screw-threaded block S, which is positioned in the end of the casing. As this Screw-threaded block is adjusted the tension of the spring is varied, as will be readily understood.

When it is desired to retain the door at any particular point, the foot is placed upon the cap G of the plunger and the latter depressed, the bolt slidin g on the ratchet and permitting said movement, and when the iiexible plates engage the iioor the foot is removed from the plunger and the latter retained by the bolt.

For releasing the bolt from the ratchet of the plunger and permitting the upward move ment of the latter I provide the depressible rod T, having one of its sides inclined, as illus trated at T, said rod passing through the casing and through the slot O in the bolt, a pin U being inserted through the lower end thereof on the under side of the casing to prevent its removal from the latter. A spring V` is coiled about said rod on the upper side of the casing and is retained in position by a screwthreaded cap V', which engages the upper screw-threaded end of the rod, so that IOO the tension of said spring may be varied. When this rod is depressed through the medium of the inclined edge engaging the slot of the bolt, the latter is moved from engagement with the ratchet,when the spring L will return the plunger to its normal position out of engagement with the licor. As soon as the foot is removed from the depressible rod the spring V returns the same to its normal position and the spring R presses the bolt into engagement with the ratchet of the plunger.

In Fig. (5 I have illustrated a slight modification of the plunger, in which, instead of providing a plate F at the lower end thereof, I bifurcate the end of the plunger and bend said bifurcated portions in opposite directions and at right angles to the plunger, securing the flexible plates to the under sides of these bifurcations, as clearly illustrated.

From the above description it will be seen that I have produced a very simple construction of door-stop which is positive and reliable in its action and by means of which the door` may be retained at any desired position.

While I have illustrated and described the best means now known to me for carrying out my invention, I do not wish to be understood as restricting myself to the exact details of construction shown and described, but hold that any slight changes or variations such as might suggest themselves to the ordinary mechanic Will properly fall within the limit and scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. In a door-stop, the combination of a depressible plunger, a spring-held bolt adapted to engage the same and provided with a slot, and a depressible rod movable through said slot and having an inclined surface by means of which the bolt is retracted when said rod is depressed, substantially as set forth.

2. In a door-stop, the combination of a casing, a plunger movable vertically therethrough and provided with a ratchet and a Ascrew-threaded upper end,said plunger adapted to engage the floor at its lower end, a spring coiled about the upper end of the plunger, a screw-threaded cap engaging the screwthreaded end of the plunger and adapted to vary the tension of thc spring, a spring-actuated bolt movable longitudinally in the casing and adapted to engage the ratchet ot the plunger, and means for retracting said bolt, substantially as set forth.

OLIVER C. CONERLY.
