To all 'whom t my concern:

Be it known that l, GEORGE DAMANIS, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Locks; and lf do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it a pertains to make and use the same.

ltly invention relates to improvements 1n house and apartment door locks and more particularly to those of the type having a locking bolt which is tripped by lnward movement of the= usual beveled latch, incident to closing the door, whereby said locking bolt is projected to co-act wilth the latch in doubly locking the door.

One object of my invention is to provlde alock of the character set forth provided with means for locking the bolt against projection every time the door is closed, for instance during the day time, this means, however, being movable to an inoperative position so that whenever it is desired to have the bolt project automatically with closing of the door, this can be done.

A further object is to provide improved means for tripping the bolt holding tumbler when the door is closed, permitting a spring to come into play to project the bolt.

Yet anotherobject is to provide a novel arrangement of parts whereby both the locking bolt and the latch may be simultaneously retracted by means of a key, the bolt being held in retracted position while the latch is released to be again projected under the influence of its spring.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure 1 is an elevation, partly in section, showing a lock constructed in accordance with my invention, the bolt and the latch being shown in locked position..

Figure 2 is a view similar to Fig. 1, showing the locking bolt and the latch partially withdrawn.

Figures 3 and t are detail perspective views showing the additions which l have made to a well hewn lock structure, to carry out my invention. v y

lfn the drawings above briefly described, the numeral ldesignates a suitable lock casing containing a spring pressed beveled latch 2 and a locking bolt 3 provided with a projecting spring d. A spring-applied tumbler 5 is pivoted at 6 to the locking bolt 3 and is cooperable with a post 7 in the casing to hold the bolt in either projected or retracted position. The numeral 3 merely designates a well known rocker controlled by a finger piece from the inside -of the door,

for releasing thetumbler 5 and retractingl the. locking bolt 3 when desired, without the necessity of using a key. When it is desired to hold this bolt in retracted position, regardless of release of its tumbler 5 by means yet to be described, this may be done by means of a pin 9 passing slidably through a slot 10 in the casing and capable of being moved into engagement with a shoulder 11 on the bolt 3, when the latter is fully retracted.

For retractin the lock 3 by hand, and releasing its tum ler 5, an ordinary cylinder type of locking mechanism is provlded within an opening 12 in the casing, this mechanism. however being omitted for sake o clearness.

'lhe numeral 13 designates a lever which may well be ulcrumed upon the post 7, the lower end of said lever having a pin and slot or other suitable slidin" connection 14 with the latch 2, while t e upper end of said lever is provided with a shoulder 15 engaged by a nose 15 on a cam 16 located behind the bolt 3 and pivotally mounted on a suitable stud or the like 17. A cam actuator 18, preferably in the form of a horizontal lever, is fulcrumed at 19 to the bolt 3 and as here shown, is provided with a lateral lug 20 cooperable with the curved edge 21 of the cam 16, for thev purpose of rocking said cam about its pivot 17, as the actuator 18 is forced inwardly by inward movement of the bolt 3, under the iniuence of the key operated mechanism. The end of the actuator 18, remote from its pivot 19, is connected by means of a link 22 or other suitable means, to the tumbler 5. Since the actuator is tied to the tumbler 5, it cannot have vertical movement independent of the tumbler and therefore the actuator will be held against upward swinging when the bolt 3 moves inwardly andconse uently causes the lug 20 to tilt the cam 16 ownwardly and furthermore, when the bolt is fully retracted and the tumbler 5 ava-in rises to an operative position to holdD said bolt retracted, the tumbler pushes upwardly upon the link 22 and thus swings the actuator 18 upwardly, thereb releasing the pressure of the lug 20 upon the cam 16 and permitting the latch 2 to again project under the influence of its spring. rlhis spring, a portion of which is designated by the reference character 23, may well act upon the lever 13.

While any desired connections may be employed between the link 22 and the parts 5 and 18, l prefer to establish these connections by means of loosely intertting notches in the several parts as shown more particularly at 24 in Fig. 3.

From the construction so far described, it will be seen that when the bolt 3 is moved inwardly by key operated mechanism (not shown) the lug 20 and the actuator 18 tilt the cam 16, therebyrocking lever 13 and retracting the latch 2, so that the door.

can be opened. As soon as the key operated mechanism however permits the tumbler 5 to come into play to hold the bolt 3 retracted, the link 22 moves the actuator 18 upwardly, releasing the vpressure of lug 20 on cam 16 and permitting the latch 2' to again project, while the bolt 3 remains retracted. Now, it it is desired that the bolt 3 shall not be projected the next time the door is closed, the pin 9 is moved into engagement with the shoulder 11. Utherwise, closing of the door and inward movement of the latch 2, incident to this closing, will cause projection of the bolt 3 under the infiuence of its spring 4c, due to the tact that ll provide a pin or other projection 25 on the lever 13 for contacting with and releasing the tumbler 5 when the latch 2 is moved inwardly.

Assuming that the bolt 3 is held in retracted position by the tumbler 5, that the pin 9 is not engaged with the shoulder 11, and that the door is in open position, it will be seen that closing of this door will cause the latch 2 to move into-the casing, thus rocking the lever 13 and causing pin 25 to release the tumbler` 5, whereupon the spring t comes into play to automatically project the bolt 3 for cooperation with the latch 2 in doubly locking the door.

As excellent results may be obtained from the details disclosed, they are preferably followed, but it is to be understood that Within the scope of the invention as claimed, numerous minor changes may be made. For instance, although ll have used well Lavaeaa known lock parts and have merely added' the link 22 and the pins 9 and 25, it will be understood that if desired, the invention can be carried out in other ways. It may me further stated that all parts shown below the broken. line'A, are well known, for the purpose of controlling the latch 2 by hand from the usual knob shaft.

I claim:

1. A lock comprising a casin containing a spring-pressed latch, a loc -controlled bolt and a lock-controlled tumbler for said bolt; a movable member mounted in said casing and operatively associated with said latch for withdrawing the same, an actuator for said movable member mounted movably on said bolt and operative to effect withdrawal of said latch automatically when the bolt is withdrawn, and a connection between said actuator and said tumbler for automatically movin said actuator out of operative relation wit said movable member when said tumbler returns to operative position with the bolt retracted.

2. A lock comprising a casing containing a spring-pressed latch, a lock-controlled lbolt and a lock-controlled tumbler for said bolt; a movable member mounted in said casing and operatively associated with said latch for withdrawing the same, an actuator for said movable member mounted movably on said bolt and operative to eect withdrawal of saidlatch automatically when the bolt is withdrawn, and a link connecting said actuator with said tumbler for automatically moving said actuator out of operative relation with said movable member when said tumbler returns to operative position with the bolt retracted. i

3. A structure as specified in claim 2; the connections of said link with said tumbler and actuator being eifected by providing said link, tumbler and actuator with loosely interitting notches.

4. A door lock comprising a casing containing a spring pressed beveled latch, a spring-projected locking bolt and a tumbler for normally holding said bolt retracted; means in the casing, for automatically retracting the latch when the bolt is retracted, including a movable member adjacent said tumbler, and a projection on said member operative to release said tumbler and thereby eect projection of the bolt automatically when the latch is forced inwardly by closing the door.

5. A door lock comprising a casing containing a spring pressed latch, a beveled, spring-pressed lock-controlled bolt and a lock-controlled tumbler for said bolt; a lever fulcrumed in the casing and extending transversely of the bolt, said lever being con.- nected with said latch, a movable member mounted in the casing and acting on said lever for retracting the latch, an actuator for said movable member mounted movably the latch, and a projection on said lever on the boltand active to eect retraction of adapted to strike and release said tumbler the latch when the bolt is retracted, means when 'the latch is forced into the casing by 10 for automatically disengagmg said actuator closing of the door.
