EUGENE LAWSON, OF WILKES-BARRE, PENNSYLVANIA.
DOOR-CHECK.
SPECIFICATION forming part of Letters Patent No. 416,465, dated December 3, 1889.
Application filed May 18, 1889. Serial No. 311,276. (No model.)
To all whom it may concern.-
Be it known that I, EUGENE LAWSON, a citizen of the United States, and a resident of ilkes-Barr, Luzerne county, Pennsylvania, hai e invented certain Improvements in Door Stops and Retainers, of which the following is a specification.
The object of my invention is to make a door or shutter stop and retainer in a simple manner that will be strong, effective, and hold the door or shutter rigidly.
My invention is especially applicable for use in connection with the doors of railwaycars and in public places, where a secure and strong stop is desirable.
In the accompanying drawings, Figure'l is a perspective View of the ball and the socket of the stop detached from each other. Fig. 2
. is an end view looking atthe mouth of the socket. Fig. 3 is a plan View of the ball and socket detached, and Fig. 4 is a view showing the ball and socket attached.
A is the socket, having a screw a for application to the door or to the wainscoting of the room or apartment. The socketA is made of one casting and has arms I) b, the inner edges of which are curved, as shown at c c, and flare, as shown in Figs. 1 and 2, to the ends d d. The space on the line so is a trifle narrower than the largest diameter of the ball B, which is rounded, as shown, and is provided with a screw 6 for application to the door or wainscoting. hen the ball is forced into the socket, as shown in Fig. 4, the
spring receives the thrust.
arms I) b will yield sufficiently to allow the ball to pass the narrowest portion :12, and will hold the ball in position, thereby holding the door open. In the socket is an orifice f, in which is a coiled spring F, extending into the opening formed by the arms I) b, so that as the ball is forced into the socket this I also prefer to provide the ball with a spring g, of rubber, adapted to an orifice in thewall, which abuts the spring F when the door is open, and the two springs force the ball against the arms I) b, preventing shaking of the door, which is objectionable, especiallyin railway-cars. The socket may carry the rubber spring and the ball the coiled spring. By having one a metalhe spring and the other a rubber spring the action is much easier and noise is prevented.
It will be understood that the stop may be used as acupboard-catch to hold adoor closed instead of open.
I claim as my invention- A door stop and retainer made of one casting having the body A, two arms Z) b, with flaring ends, and screw a, substantially as and for the purpose described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
EUGENE LAWSON.
