LOCK.

Application filed June 23, 1921. Serial No. 479,729.

To aZZw/wm it may concern:

Be it known that I, Oscar: C. Rrxson, a citizen of the United States, residing at New Rochelle, in the county of lVestchester and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and

exact description.

My invention has especial application to mortice locks which are operated by a separate pin tumbler key operated lock, the tumbler lock with the key plug being exposed usually in an escutcheon or other ornamental device, in the side of a door. in most cases and particularly with outside doors, it is desirable for the sake of appearance to have the escutcheon or the exposed end of the key operated lock centrally located in the stile of the door. To satisfy this requirement the dimensions of the lock must be such that the back set of the key mechanism, i. e., the distance from the key hole to the face plate, is substantially equal to half the width of the stile. It has therefore been necessary for supply dealers to carry in stock several numbers of locks differing from each other essentially only in the distance between the face plate and keyoperated lock.

An object of my invention is to provide a lock which may be adapted to various widths of stiles, thereby reducing the numbers of locks which a dealer must carry in stock, and in accordance with my invention I make the back set of the key mechanism adjustable so as to bring the escu-tcheon into the desired relation to the stile of the door.

Preferably the angular disposition of the key mechanism is substantially unchanged in any adjusted position, since it is desirable that the key slot should be vertical in the locked and unlocked positions of the key plug. l/Vhere, for instance, the adjustment is effected by an arcuate movement of the key mechanism, a suitable connection may be provided between the key mechanism and the face plate which will permit of the arouate movement of the shell while restraining it from rotative or angular movement.

My invention also comprehends various other features of construction which will appear more particularly from the description of the embodiment of my invention selected for the purpose of illustration and shown in the accompanying drawings, in which Figure 1 is a side elevation of a complete mechanism embodying my invention;

Figure 2 is a rear elevation of the same;

Figure 3 is a longitudinal sectional elevation of the same on line 8-3 of Fig. 2;

Figure 4 is a transverse section of the supporting frame and shell on line 1- i of Figure 1; and

Figures 5 and 6 are details in side and inner end elevation of the key mechanism.

The illustrated lock mechanism is of the type in which the face plate 1 is covered by a finishing and protecting plate or mask 2, usually of brass, which prevents access to mechanism within the mortice in the door and minimizes the likelihood of unauthorized tampering with the lock. The housing of the mortice lock, consisting of the two" cover or side plates 3 and 4, is secured to the face plate 1 in any suitable way, as by screws 5. The bolt 6 is actuated by an operating member or lever 7 which protrudes through the top of the mortice lock housing and is itself operated by the key mechanism, as will be hereinafter described. A latch member 8 is pivoted within a recess in the side of the bolt 6, being pivotally connected at its free end to the operating member 7. A fiat spring 9 tends to hold the latch 8 elevated with its two shoulders 8 and 8 behind a lug 10 on the cover plate 5 of the lock, in the unlockedand locked position of the bolt, respectively, and in throwing the bolt it is therefore necessary first to depress the free end of the latch 8 suflicient to clear the lug 10.

The key mechanism consists of the usual cylinder pin tumbler lock 11 having an eccentric key plug on the inner end of which is the cam or roll back 12. Qnly one of the key mechanisms is shown, although manifestly another may be employed on the opposite side of the door. To receive the key mech anism a shell 13 is employed, which has two lateral trunnion projections bearing in circular openings in two parallel plates 14: and 15 secured together by rivets 16, as shown, and pivoted at their lower end by screws 17 to the mortice lock. They are further secured together at their centers by ascrew 18 which passes through an opening in the operating member 7 and serves as a fulcrum therefor.

' screw in stops 1-9"onthe'cover plates determine the.

swinging movement of the plates 1%.- and 15 and the mechanism carried thereby.

The trunnion projections of the shell 13' are hollow and provided with internal screw threads into which are received the inner screw threaded ends of the key mechanisms 11. The key mechanisms are screwed within the shell until the end of the operating member 7 lies within the path 0t movement of the roll back 12, and are then locked against rotation therein by the respective set'screw 20 which engages in a groove in the side of the cylinder, one groove being provided in proper position in each side to make the cylinder reversible. The face plate 1 is provided with a hole 21 opposite the heads of the set screws 20, which affords access with a proper tool to the set screws when the cover plate 2 is removed.

It .is now manifest that by turning the key the roll back 12 is caused first to depress the member 7 to cause the latch 8 to clear the lug. 10, and that the further movement of the rollback causes the member 7 to bear against the fulcrum 18 and throw the bolt either in or out.

To swing-- the key mechanism upon the pivots 17 and vary its back set or distance from'the face plate, a screw and nut mechanism is employed; The shell 13 is provided at its top with an elongated longitudinally extending nut 22 and a feed screw 23 engage'sl in this nut and has its head bearing loosely in a counter-sunk hole in the face plate 1'. By turning the screw 23 by means of a screw driver applied to either end the keymechanismis swung, upon the pivots 17 and" at the same time the cylinder and shell are held in substantially'the same angular position by reason of the long bearing of the I the lug or nut 22. The bearings therefore rotate about the trunnions as the partsare adjusted. Because of the relative thinness of the face plate the head of the feed screw 23 has a certain freedom of movement which prevents binding of the parts. By the adjusting operation above described, it will be seen that the key hole of the lock can be located at the exact center of the stile of the door thus making the lock of universal application to doors having different widths of stiles.

It is manifest that the invention is' in no wise limited to any particular type of key mechanism, and in fact comprehends the combination with any, lock operating mechanismwhether' a door knob, thumbtii'rn,'bitted' key; mechanism, or other expedi'ent;

It is obvious that various modifications may be made in the construction shown and described within tllfilDi'iilC-ljfilfl and scope of my" invention.
