/8 55mm: .6. R677! Patented Mar. 3, 1936 UNITED STATES PATENT OFFICE 3 Claims.
character stated which is simple in construction and inexpensive to manufacture, and which can be effectively latched from one side, when desired.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.
In the drawing Figure 1 is a side elevation of my lock with the cover plate removed.
Figure 2 is an end view of the lock in position in the door.
Figures 3, 4 and 5 are side elevations of different guards or wards.
Figure 6 is a top plan view of the safety guard.
Figure 7 is a top plan view of the bolt.
Figure 8 is a fragmentary side view of a key to operate the lock.
Referring more particularly to the drawing, the numeral I indicates the lock case made of metal and preferably stamped into a rectangular shape. A bolt 2 is horizontally slidable in the case and projects from one side of the case in the usual and well known manner. This bolt co-acts with the usual strike plate, as is understood by those skilled in the art.
A block 3 is set into the end of the bolt 2 and is held by the portion 4 which is within the case I. A machine screw 5 extends thru the part 4 and the block 3, thus removably holding the block in position. The purpose of this arrangement is to permit the block 3 to be turned over so that the door lock can be used either right or left.
A lug 6 is struck up from the case I and fits into a horizontal slot I in the member 4. A spring 8 bears against the lug 6 and against the inner face of the block 3, thereby yieldably urging the bolt outwardly. The lug 6 also acts as a stop for the bolt to limit its outward movement.
A roll back 9 is mounted within the case I and is operated by a knob stem III which stem extends thru the roll back, as shown in Figs. 1 and 2. The lower end of the roll back extends into a notch II in the upper face of the part 4, and engages the rear side of the notch 4. Thus, by turning the knob, the bolt 2 is retracted to open the door.
A latch pin I2 is mounted on one side of the door and projects into the case I. A slot I3 is provided in the roll back 9 to receive the inner tip of the pin I2. When the pin I2 is moved into engagement with the roll back 9, the door knobs cannot be rotated, thus providing a night latch for the look.
A spring I4 presses against the upper fiat surface of the roll back 9 to yieldably hold the roll back in vertical position so that the latch pin I2 will always readily enter the slot I3.
The bolt 2 may also be operated by means of a key I5. The case I has a key hole I6. Only one escutcheon has a key hole corresponding to I6. The key hole I6 is in the side opposite the latch pin I2. The bolt 2 has a notch IT in the lower edge thereof into which notch the bit I8 of the key enters, to retract the bolt.
A plurality of ward blocks I9 are mounted adjacent the key hole I6 to control the key I5, and only permit a key of the proper design to open the lock. The wards I9 are provided with varying curved surfaces 20, which surfaces are traversed by notches in the bit I8 when the proper key is inserted and rotated to retract the bolt. The wards I9 are slidably fitted upon a stud 2| in the case I. The lower edge of all the wards is fiat and rests upon the bottom of the case I. Thus, it will be evident that the wards are all held in proper alignment and in proper spaced relation to the key hole I6.
The key I5 can only rotate in one direction to retract the bolt, and to prevent the key from rotating in the wrong direction, I provide a guard 22 which is fixedly mounted in the case I.
The lip 23 of the guard is curved so as to fit over the key hole I6 and the center of the curvature of this lip corresponds to the longitudinal center line of the key I5. A slot 24 in the bit I8 is arranged so as to receive the lip 23, as shown in Fig. l. The guard 22 acts as a further guarantee against the use of an unauthorized or improper key.
Having described my invention, I claim:
1. A look comprising a case, a bolt slidably mounted in the case, said case having a key hole below the bolt, a plurality of wards removably mounted in the case adjacent said key hole, and a guard in the case above said key hole, thereby preventing improper rotation of a key in the lock.
2. A lock comprising a case, a horizontal bolt in the case, spring means engaging the bolt whereby said bolt is urged outwardly, said case having a key hole adjacent the bolt, a plurality of wards positioned on one side of the key hole, a cover on the case, a stud fixedly mounted in the case, said wards being slideably mounted on the stud and interchangeable thereon, each of the wards having a curved surface thereon over which a key moves, a guard mounted in the case on the opposite side of the key hole from the wards and a curved lip on the guard extending over the'top of the key hole.
3. A look comprising a case, a horizontal bolt in the case, spring means engaging the bolt 7,
whereby said bolt is urged outwardly, said case having a key hole below the bolt, a horizontal stud fixedly mounted in the case, a plurality of wards slideably mounted on the stud, said wards positioned at one side of the key hole, each ward having a curved surface presented towards the key hole and a fiat bottom surface adapted to rest on the bottom of the case whereby said wards are interchangeably positioned on the stud, a guard fixedlymounted in the case, said guard being positioned on the opposite side of the key hole from the wards, a curved lip on the guard extending over the top of the key hole.
GEORGE B. PE'I'I'Y.
