LOCK.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed June 5, 1920. Serial No. 388,666.

T 0 all whom it may concern.

Be it known that I, Monnis Snmxanxx, a citizen of the United States of America, residing at New York city. Bronx county, State of New York, have invented certain new and useful Improvements in Locks, of

which the following is a full, clear, and exact description.

T his. invention relates to improvements in locks, more especially locks for doors and the like, one of the objects of my invention being to provide a lock so arranged as to prevent the door from being forced by being lifted upwardly. to accomplish this result, I provide means independent of the bolt of the lock to engage means carried by the frame for the door, preferably on the striker-plate, the engagement oi": the parts being automatic and in no way dependent upon the bolt or means to actuate the bolt. A further object of the invention is to provide a lock and striker-plate which are located cxteriorly of the door and door frame, respectively, said lock having a vertically movable bolt arranged to engage locking elements carried by the striker-plate. he lock and striker plate will of course be located on the inner exterior surface of their respective elements, or in other words on the sides of said ele ments which are within a room or the like. Further features or improvements will hereinafter appear.

I will now proceed to describe my invention in detail, the novel features of which I will finally claim, reference being had to the accompanying drawing, wherein Figure 1 is a fragmentary view in elevation, illustrating my improved lock mechanism;

Fig. 2 is an enlarged detail view 01" the lock and striker-plate;

Fig. 3 is an enlarged sectional plan view, the section being taken on a line 33 in Fig. 1;

Fig. 4 is an enlargedcross sectional detail view. the section being taken on a line l-4 in Fig. 3;

Fig. 5 is an enlarged end view, illustrating the striker-plate;

Fig. 6 is an enlarged detail view of the lock, the cover plate being removed;

Fig. 7 is a longitudinal sectional view thereof, the section being taken on a line T-7 in Fig. 6; and

Fig. 8 is an enlarged fragmentary detail view illustrating my improved mounting for the cylinder lock mechanism. 7'

My improved device consists oi a bolt supporting casing 9, which is secured to a door or the like, indicated by 10. and a cooperating striker-platc 11, mounted on the door frame 12. The casing 9 carries a bolt 13 operable by rotatable fingers 14 and 15 which in turn are actuated by a. handle or knob 16 secured to the rotatable bushing 17 which carries lingers 1 1- and 15. The inner end of the shank 18 or? the bolt 13 carries a tumbler l9 pivoted at 20 to said bolt. said tumbler being arranged to a keeper 21 carried by the casing 9 l hen the tumbler 19 is in the position indicated in Fig. 6, the bolt cannot be raiser. Alter tumbler 19 has been moved from the position indicated in Fig. 1 to clear the keeper 21, the bolt can be raised (see dotted lines 22 in Fig. 2), after which the nose 23 of tumbler 19 will rest upon the k eper 21, thereby preventing the lowering oi the bolt 13. The tumbler 19 is actuated to clear the keeper by the finger 1 1 or finger 15 according to the direction of rotation of knob 16. lVhen knob 16 is rotated in the \ill'QC QlOI l of the arrow in Fig. 6, finger 15 will contact with projection 24; on tumbler 19 and move the latch away from the keeper 21. A continued rotation of the said knob will cause the finger 15 to contact with the project-ion 25 on the shank 18 of bolt 13 and finally move the bolt in the direction of the arrow 26 in Fig. 6, or to the position. indicated by dotted lines in Fig. 2, after which the tumbler 19 will engage the top surface of the keeper 21 and said bolt will be locked against downward movement until the tumbler is again actuated. When the bolt 13 is in the uppermost position, the door 10 may be opened. lVhen knob 16 is turned in the opposite direction. tumbler 19 will be again actuated and the bolt will be moved down, for the reason that the finger will strike the other projection 27 on the shank of the bolt and actuate same. As the knob will be located on the inside of a door, the above operations can take place from within a room only.

To actuate said bolt by a key from the outside, I pro *ide the ordinary cylinder lock mechanism indicated by 28, said mechanism the door is closed,

bolt actuated by a key in bein connected by the usual plate to a rotatable bushing 30 having a finger 31 to actuate the tumbler 19 and bolt 13 (sec Fi 7).

l. s can be seen in Fig. 6, the bolt 13 is in the form of a T having a head 32 and a guide plate adjacent the head to provide slots 3t to receive the guides 35 carried by the casing 9. The guides 35 are spaced apart to provide a jaw 36 to receive an abutmentblock or aliner 3'7 carried by the strikerplate 38 which is mounted on the face 39 of the frame 12 of the door. In other words, the guides 35 are extended beyond the coverplate 40 which carries the bushing 30, to overlap the end surface 1-2 of the door 10 (see Fig. The guides lie against the end surface of the door and are secured to the door by screws 43. The abutment 37 projects from the member s 1 of the strikerplate to enter between the guides 35 when as indicated in Figs. 3 and t. The member 15 of the striker-plate, which is disposed in this instance at a right angle to member Mr, carries (in this instance) two studs 4-5 having heads d6 which are larger in diameter than the shanks l? of said studs. The studs 15 act, in conjunction with belt 13, to prevent the door from being opened from the outside, unless said manner described. To coiiperate with the studs the bolt 13 is provided with openings 18, said openings being made up of a slot 49 having in communication therewith passages 50. The width of the slots 48 slightly exceed the diameter of the shanks d7 of the studs 45, while the passages 50 slightly exceed in diameter the diameter of heads 16 of said studs 45. l/Vhen bolt 13 is raised as per dotted lines Fig. 2, the heads of the studs {l5 and passages 50 will aline, but when the bolt 13 is lowered, or rests in itslowest position, the shanks 4:7 of the bolts will be engaged by the slots d0, that is to say, when the door is closed and bolt 13 is in its lowermost position, said'door cannot be opened, as the heads of the studs will prevent the door from being moved upon its hinges,one being indicated by 51 in 1. At this time, that is to say, when the door is closed, block 37 on the striker-plate will be located between the guides 35, as indicated in Fig. l; hence the door cannot be forced upwardly thereby causing the bolt 13 to be raised su liciently to cause the heads of the studs 45 to aline with the passages 50. It will be apparent that the block 37, bolt 13 and studs 45 cooperate to prevent the door from being opened unless the lock is actuated by a key from the outside or from the insidev by turning knob 16.

The cover plate 4C0, which carries the bushing 30, is secured to the casing 9 by screws the bolt 13 to prevent the door from being forced open .by an instrument inserted be-' tween the door and easing along the edge 56 of said door, or rather it reinforces the casing 9 as any strain on the casing in the direction of arrow 57 will be transmitted to the bolt through the guides 35 and lip 50; hence the lip will reinforce the casing.

To render the cylinder lock 28 adjustable, to accommodate doors of various thicknesses, I provide studs 58 which are carried by the cover platedO and extended into an opening 59 formed in the door 10L The studs 58 ar notched as at 60 to receive set-screws 61, one only being shown in Fig. 8. The cylinder 28 can be adjusted longitudinally of the studs 58 and secured in adjusted position by the set screws 61, which will engage the notch 60 in alinement therewith. The plate 29 will, of course, be long enough to permit considerable adjustment on the part of the cylinder 28.

What I claim and desire to secure by Letters Patent is r 1. In a lock mechanism, a striker plate, a projection carried thereby having an enlarged portion, a bolt movable in parallelism with said plate in a vertical plane and having an opening to permit of the passage of the enlarged portion of said projection, said hole having a slot in communication wit said passage to engage the smaller portion, of said projection, a'casing for said bolt having a jaw, and a projection carried by the striker plate to engage said 2.
