Description

,i UNITEDv STATES Patented April 4, 1905.
PATENT OFFICE.
GEORGE H. WOLF, OF WASHINGTON, PENNSYLVANIA, ASSIGNOR OF ONE-FOURTH TO ALFREDL. COCHRAN, OF WASHINGTON,
PENNSYLVANIA.
ADJUSTABLE DOOR-STOP- SPECIFICATION forming part of Letters Patent No. 786,782, dated April 4, 1905.
Application iiled November 15, 1904l Serial No. 232,805.
T all whom/ t may concern.-
Beit known that I, GEORGE H. WOLF, a citizen of the United States, residing at Washington, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Door- Stops; and I do hereby declare the following to be a full, 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.
My invention relates to door-stops, and particularly to that class of stops used for cupboard-doors.
The object of the invention is to provide a stop which will prevent the door from coming in contact with the wall, thus preventing the door from injuring the plastering.
With this object in View I will now describe my invention, reference -being had to the accompanying drawings, in which similar letters of reference indicate corresponding parts in the dierent figures thereof.
Figure l represents a front View of a cupboard with the door open, showing my improved stop applied thereto. Fig. 2 is a side elevation of the device removed. Fig. 3 is an inverted plan View of one of the parts detached. Fig. t is an end View of the adjustable stop. Fig. 5 is adetail view of the other plate, and Fig. 6 is a detail View of the arm or lever employed.
The device is constructedas follows: A plate a, provided with two flanges forming a recess is secured to the door, and another plate, c, provided with a lug d, is secured preferably to the under side of one of the shelves. Pivotally connected to the plate a is a radiallycurved arm or lever e. The opposite end of said arm or lever is inserted through an eye f, formed in the plate c, and is provided at or near its outer end with an adjustable stop g, the purposeof which is to adjust the length of the arm or lever and prevent the door from swinging too far open. The plates a and c are secured to the shelf and door by means of screws, and the stop on the arm or lever is held in position by means of a set-screw It. The plate c is preferably tapered, as shown, so that the stop will gradually come in contact with it, forming a friction, thus preventing the door from partly closing in case it is thrown back with too much force.
Having described my invention, what I claim is- An adjustable door-stop, comprising a plate c, adapted to be secured to a door, a radiallycurved arm or lever pivoted thereto, an inclined friction-plate secured to a shelf and provided with an aperture for receiving the opposite end of said arm or lever and allowing same to slide freely therein, together with an adjustable stop upon the free end of the curved arm for limiting .the movement of said arm or lever, all substantially as and for the purposes shown and described.
' In testimony whereof I have hereunto set my hand in the presence of two witnesses. GEORGE H. WOLF.
Witnesses: BOYD E. WARNE, MARK M. DECKER.
