WILI-IELM ADAM, OF GELSENKIRCHEN, GERMANY.
DEVICE FOR LOCKING DOORS.
Specification of Letters Patent.
Application filed February 6, 1911.
Patented Aug. 13, 1912.
Serial No. 606,837.
To all whom it may concern Be it known that I, l/VILIIELM ADAM, a subject of the German Emperor, and resident of Gelsenkirehen, Germany, have invented certain new and useful Improvements in Devices for Looking Doors, of which the following is a specification.
This invention relates to an improved device for locking doors, which can be used either separately or in addition to an ordinary door-lock and which is represented on the accompanying drawing, in which Figures 1 and 2 are front views of the same in locked and unlocked position respectively, while Fig. 3 is a plan view of the device.
The device is arranged at the inner side of the door, in which above the same a keyhole is provided. Through the round opening of the latter, a key a with drop-lever I) can be inserted, the latter placing itself by its own weight rectangularly downward into its position of use. By turning the key a in the direction of the arrow (Fig. 2), drop lever Z) passes the horizontal guiding templet or ward plate 0 and abuts then against the pin 03 of the bolt 6 which is then brought into the locked position by further turning the key. The drop lever is fitted with corresponding bits to the wards in said teinplet so as to exactly fit the same upon its passage theretln-ough. For again opening the bolt, the key is turned in opposite direction, see arrow Fig. 1, in which case it must also first pass through the guiding templet c.
I claim:
In a device for locking doors, in combination a locking bolt at the inside of the door, the latter having above said bolt a keyhole, a pin on said bolt, a fixed horizontal guiding teinplet above said bolt having wards therein, and a key with drop lever having bits thereon to exactly fit the wards in said templet, said key being adapted, when passed through the keyhole, to engage said pin and thus to operate said bolt upon the drop lever having passed the wards in said templet, for the purpose set forth.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
VVILHELM ADAM.
