WILLIAM BOETTCI-IER, OF CHICAGO, ILLINOIS.
' DOOR-STOP.
Application filed March 10, 1909.
To all whom it may concern:
Be it known that I, WILLIAM BonTTcHER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Door-Stops; and I do hereby declare the following to be a full7 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a novel construction in a door stop, the object being to provide a simple, eiicient and durable device of this character which is small and compact and consists in the features of construction and combinations of parts hereinafterfully described and claimed.
In the accompanying drawings illustrating this invention: Figure 1 is a view in front elevation of the door stop showing it attached to a door and the plunger depressed into engagement with the floor. Fig. Q is a central vertical section of the same on the line 2 2 of Fig. l Figs. 3 4 and 5- are detail plan sections on the lines 3 3, 4 4 and 5 5 respectively of Fig. 2
My said device comprises a hollow casing 1 open at one side and at one end and terminating opposite the` open side in a semicylindrical portion 2 At the edges of the walls bordering the open side of the casing are two lateral projections 3 .having countersunk openings therein to receive the screws 4- by means of which said casing is secured to the door. The upper wall 5 of said casing is provided on its free edge With an elongated flange 6 provided with a countersunk opening to receive the screw 7- by means of which the same is secured, said flange 6 being disposed in the same plane as said flanges 3 In the upper wall 5 of said casing concentric with lthe semi-cylindrical wall thereof is an opening through which a hollow plun ger 8- projects. The latter projects also through a similarly disposed opening in thev partition wall 9- disposed parallel with the wall 5 substantially midway between the ends of said casing. In the side Walls of said casing at the free ends thereof and substantially midway between the top wall 5 and partition wall 9 are provided two horizontally disposed recesses 10 in which the projections l1 on Specification of Letters Patent.

Serial No. 482,581.
the Yside edges of the clutch 12 are adapted to be received. The said clutch l2 .consists of a flat plate of steel or other relatively hard metal and is provided with an opening l3 of slightly greater dimensions than the openings in the walls 5 and 9 The said plunger 8 passes through said opening 13- and is engaged by the sharp corners of the walls of the latter when said clutch is slanted in the position shown in Fig. 2- and serves to hold said plunger against movement in one direction. This clutch is so well-known and so commonly used in devices of this character as to render detailed description of its operation superfluous. A spring 14.- supports the free end portion of said clutch l2 said spring being supported upon the partition wall 9- and held against displacement by means of segmental projections or flanges l5 integral With the semi-cylindrical wall of said casing. In alinement with the seat for the spring I4- thus formed is an opening in the upper wall 5 of said casing through which a pin 16- passes, the 'latter having a head 17 of larger diameter which engages the lower face of the wall-- around said opening to prevent the loss of said pin. The said head 17 bears upon the upper' face of said clutch l2 at its free end and serves when said pin is depressed to depress the free end portion of said clutch against the action of said spring 14 The said plunger 8 1is tubular and is provided between its ends with a partition wall 18 The shank l9 of a plunger 20- enters the lower end of said plunger 8 and is held against removal by means of a pin 21 passing laterally through said shank l9 and through longitudinal slots 2Q- in the wall of said plunger. A spring 23 interposed between said partition wall 18 and the upper end of said shank 19 serves to normally maintain said plunger at the lower limit of its movement. A foot-piece 24 preferably of rubber or some flexible frictional material is suitably secured within the recessed lower end of said plunger 20 In the upper end portion of said plunger above the said partition wall l8- therein is a spiral compression spring 25 which bears at one end against the plug 26 closing the upper end of said plunger. The projection 27 of a plate 28- secured by means of a set screw 2Q- to the upper wall -5- of said casing projects through the longitudinal slot in the upper end portion of said plunger -8- and supports said spring -25- at its lower end, the said spring serving to normally maintain the said plunger #8- at the upper limit of its movement.
My device is operated by depressing the plunger S with the foot in order. to throw the rubber foot-piece 424.- upon the floor to engage the latter. The said spring -23- is preferably very much stronger than the said spring -25- so that the pressure eX.- erted by the foot upon the upper end of said plunger -8- will cause the said spring -23 to be compressed, thus maintaining said foot-piece -24- in yielding contact with` the ioor. The said clutch -12- automatically engages the said plunger 8g when the latter is depressed to prevent upward movement of the same and to release said plunger it is necessary to depress the pin -l6-.
I am aware that my device offers no 'essential novel principle of operation, the main object thereof being to enable the device to be made more compact than it is at present oii'ered for sale. Devices of this character are not very ornamental and accordingly it is desirable that they should be seen as little as possible. My device can be made very much smaller than other devices of this nature now on the market and. is very easily and quickly assembled besides requiring less material in its construction.
I claim as my invention: f
l. A door stop comprising a hollow casing open at its lower and rear ends and adapted to be secured to a door, the open rear end opposing the face of the door, a partition wall between the ends of said casing, a verv tically reciprocating hollow plunger movable in openings in said partition wall and t-he upper wall of said casing, a compression springV in said plunger, a projection on the upper wall of said casing entering a longitudinal slot in said plunger and supporting the said spring, a spring actuated clutch disposed in said casing normally engaging said plunger between its ends, and a plunger projecting through a wall of said casing and when depressed operatively engaging said clutch to actuate the same against the action of its actuating spring to releaseV said plunger.
2. A door stop comprising a hollow casing open at its lower and rear ends and adapted to be secured to a door, the open rear end opposing the face of the door, a partition wall between the ends of said casing, a vertically reciprocating hollow plunger movable in openings in said partition wallY and the upper wall of said casing, a compression spring in said plunger, a projection on the upper wall of said casing entering a longitudinal slot in said plunger and supporting the said spring, a clutch provided at its side edges with projections entering recesses in the side walls or' the casing adjacent the free edges thereof and adapted to engage said plunger at its free end portion, a spring normally maintaining said clutch in engagement with the plunger, a socket on the said partition wall receiving said spring, and a plunger resting on the free end o said clutch and projecting through an opening in the upper wall of said casing and serving when depressed, to actuate said clutch to release said plunger.
In testimony whereof vI have signed my name in presence of two subscribing witnesses.
WILLIAM BOETTCHER.
