AUGUST ARENS, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE P. & F. CORBIN, OF SAME PLACE.
DOOR-CHECK.
SPECIFICATION forming part of Letters Patent No. 660,240, dated October E23, 1906.
Application filed April 25, 1900. Serial No. 14,247. (No model.)
To all whom it may concern.-
Be it known that 1, AUGUST ARENS, acitizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented certain newandusefulImprovementsinDoor=Checks, of which the following is a specification.
The objects of my invention are to simplify the construction and reduce the cost of manufacture of door-bolts and door-holders and to provide a novel means of holding the bolt in any desired position. The means by which these objects are accomplished are shown in the accompanying drawings, in which- Figure l is a rear view of a door-holder embodying my invention. Fig. 2 is a side View of the same with the casing in section and showing a bolt in its normal raised position. Fig. 3 is a view similar to Fig. 2, but with the bolt lowered. Fig. 4 is an enlarged door view of the gripping device for the bolt.
Referring to the drawings, A denotes the casing of the bolt, adapted to be attached to a door.
C is a footpiece for operating the bolt, having a guide D,which extends down inside of the casing. Attached to the footpiece is the bolt E, which passes through an opening in the plate F and has at its lower end the cylindrical part G, which has an elastic tip a. Within the cylindrical end is a spring I) and a washer c, which operates against a pin d, passing through the bolt E into slots f and g. This construction allows of a relative movement of the two parts of the bolt. The plate F has a bearing at one side of the easing, as against the lugs mm, and has a handle or lever K,which projects through a slot 0 in a wall of the casing. Between the plate F and the lug p isa spring M, exerting a continuous upward pressure on the plate, so that it normally occupies a position a little off the horizontal plane, as is shown in Fig. 2. The bolt E passes through an opening 0 in the plate F and is free to move therethrough in a downward direction to any extent desired; but its movement in the opposite direction is prevented because it is gripped between the upper and lower edges of the plate oil opposite sides of the opening. A pressure on the lever K sufficient to return the plate to a horizontal position releases the bolt from the gripping edges of the opening, and t a spring N, arranged around the bolt be tween a lugr and the footpiece C, returns it to its normal position. The operation of the device is very simple. A pressure on the footpiece forces the bolt down until the clas tic tip touches the floor, the parts being held in position by the gripping-plate F. A pressure on the lever K releases the bolt from the gripping-plate and the spring N raises it out of contact with the floor.
I have described my invention as it is embodied in its simplest form as a door-holder; but it is evident also that it may be used as a lock-bolt for the door when it is closed by having the bolt enter a socket in the floor or door-casing, and I intend to include herein this or any similar use of my invention.
I claim as my invention In a door-holder, abolt made up of telescoping members consisting of a cylindrical part adapted to bear upon the floor and an upper part connected to the lower part to permit of its having a relative movement with relation thereto; a footpiece on the up per section, a casing within which said bolt moves, a guide for the bolt attached to the footpiece and extending down into the casing, a spring normally holding the bolt in its raised position, a frictional clutch-plate fulcrumed in the casing and normally held in such a position with respect tothe bolt that it is permitted to move through the plate in one direction only, a hole in a wall of the casing and a lever attached to the clutchplate and extending through said opening,
Substantially as set forth.
Signed this 14th day of April, 1900, at New Britain, Connecticut.
AUGUST ARENS.
