UNITED STATES PATNT @FIFTQE.
MARTIN GEORGENSON AND RICHARD W. BURKE, OF MANITOWOC,
WISCONSIN.
LOCK-STRIKE.
Specification of Letters Patent.
Patented May '7, 1907.
Application filed February 2.1906. Serial No. 299,209.
['0 (LM whom, it may concern.-
Be it known that we, MARTIN GEORGEN- SON and RICHARD 'W. BURKE, citizens of the United States of America, residing at Manitowoc, in the county of Manitowoc and State of l' i isconsin. have invented certain new and useful Improvements in Lock-Strikes, of which the ilollowing is a specification, reference being had to the accompanying drawings.
Our invention relates to improvements in lock strikers and an object of our invention is to provide a lock striker which may be readily adjusted in case of need without removing the device from the door casing.
In the drawings illustrating the principle of our invention and the best mode now known to us of applying that principle, Figure 1. is an elevation of the parts assembled and in position; Fig. 2 is an edge view of what is shown in Fig. I Fig. 3 is a sectional View on the line AA of Fig. 1 and Figs. 4 and 5 show the striking plate and bolt-plate, respectively.
Our new lock striker is made up of two plates, the upper or striking-plate a which is iixed in position and the bolt-plate or baseplate I) which is adjustable with respect to the striking-plate and lies below it. The striking-plate a is formed with the usual strike 0 against which rubs the bolt of an or dinary knob-latch and is provided. with a central opening cl and two screw holes 6 adapted to receive the screws f. Fig. 5 shows the inner face of the bolt-plate b or the face which is opposed to the wood of the casing g. This face is corrugated as is shown at h, Figs. 3 and 5. The bolt-plate b is formed with the bolt-receiving openings 5., and with the screw-holes 7c. The latter are much larger in diameter than the screw-holes c.
\Vhen the screws f are forced home, the striking-plate o is held firmly in position and presses the corrugations h of the bolt-plate b into the wood. so that the bolt-plate is made secure in its adjusted position. When it is desired to readjust the bolt-plate I), the screws f are loosened and the enlarged diameter of the holes 70 permits the bolt-plate b to be moved relatively to the striking-plate, while the latter remains in its original position. Since the strike c remains in position, it is not necessary to cut away the wood of the casing to permit the movement of the striker, or to provide any auxiliary baseplate to cover the wood below the strike.
o claim:
In combination in a structure of the class described, a door casing; a striking plate formed with a strike and secured in a fixed position in and relatively to said door casing; and a bolt plate interposed between said door casing and striking plate and held in place by the pressure of the latter upon it; said bolt plate being adjustable in all directions relatively to said striking plate.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
