The present invention deals with locks of the type attached to doors and having a bolt adapted to removably interlock with a keeper mounted on the frame of the door. The chief object of the -invention is to provide a simplified, sturdy, efficient, and improved jimmy proof lock embodying a number of practical improvements and comprising few principal parts which may be constructed of sheet metal and readily assembled by unskilled operators. Other objects, advantages, and features of the invention will be apparent as it is better understood by reference to the following detailed description considered in connection with the accompanying drawings in which:

Fig. 9 is a perspective view of the lock closure plate.

Fig. 10 is a view similar to Fig. 5 however showing the bolt removed from the lock casing.

Fig. 11 is an elevational view of a bolt according to the invention cooperating with a slightly modified but removable connecting bar.

Fig. 12 is a sectional view taken on the line l2l2 of Fig. 11, illustrating the manner in which the connecting bar of the bolt may be attached or removed therefrom and Fig. 13 shows in perspective the manner in which part of the sheet metal plate is bent to form the lock casing.

The lock It according to the invention includes a. casing II, a bolt l2, actuating means in the form of a connecting bar l3 for operating the bolt, selective driving means 14 controlled by handle [5 accessible on the inside door face It, '5' and selective driving means I! controlled by a tongue l8 of a rotatable key receiving conventional cylinder lock l9 accessible on the outer face of the door 20. The casing ll, if desired may be of a suitable sheet metal, appropriately l0 stamped and formed to take the form illustrated and is characterized by spaced sockets 2|, 22 and 23 and the transverse wall 24 adapted to be fastened to a side face 25 of door by screws 26.

With the transverse plate 24 anchored to the 15 side face of the door, peripheral rim 2'! of casing II is against the inner face of the door, and the crank arm or driving means I4 is prop erly positioned in respect to stud 28 extending from socket 29 integral with reciprocable con- 20 necting bar l3. Crank arm [4 is fixedly fastened to the rotatable shank 30 of handle I5. Specifically however shank 30 is journalled in opening 3| of boss 32 of casing II. If therefore control handle [5 is rotated, the crank arm 14 is rotated.

Integral with and projecting from crank arm 14 is an annular collar 33 which removably receives stud 28 of socket 29. Thus if crank arm I 4 is rotated, connecting bar I3 is reciprocated longitudinally of the casing.

Advantage is taken of the reciprocation of connecting bar 13 to reciprocate the slidable bolt l2 vertically of the casing. To permit such operation, bolt I2, in the form of a stamped plate 34 to which is anchored studded block 35, includes upper and lower overhanging lugs 36 having vertically alined notches 31 in which the cross bar 38 of the bail or U shaped loop 39 is positioned, the latter having its resilient arms 40 removably snapped on and pivoted to studs 4| at opposed portions of the peripheral rim 21. As shown in Fig. 4 however, loop 39 is in its closed position, to wit, interlocked with the notches 3! of lugs 36. If therefore bar I3 is reciprocated longitudinally of the casing, the side 42 thereof cooperates with a wall 43 of the rectangular shaped slot 44 of lug 45 to slidably shift driving bolt l2 vertically in one direction relative to the casing and along the track or cross bar 38 of loop 39. In other words uponrotation of crank l4 from its position shown in Fig. 4 to its position illustrated in Fig. 5, the bolt I2 is moved from a locked position to an unlocked position, that is, studs 46 of the studded block 35 anchored to plate 34 of bolt 12 are shifted from

sockets

22 and 23 to sockets 2| and 22 respectively. It should be noted that the plate 34 of the bolt 12 is provided with lugs or books 41 receivable and anchored in notches 5 48 in the studded block 35. In effect hooks 41 are fixedly fastened to upper and lower parts of the studded plate 35 and the latter therefore bodily shift with plate 34 when connecting bar I3 is actuated.

l Reciprocable bar I3 is provided with a reduced non-circular stem 50 having one end slidably guided in a corresponding non-circular opening of a lug 52 projecting from plate 34. Abutting lug 52 is one end of a coiled spring 53 which also The other end of spring 50 surrounds stem 50.

abuts a stop shoulder 55 of an expanded part of bar l3.

When therefore crank arm I4 is rotated from the position shown in Fig. 4 towards its position in Fig. 5, bar l3 driven longitudinally of the easing but towards track 38 of loop 39. Therefore the upper face 42 of bar 13 cooperates with the upper face 43 of the guide opening 44 and hence the bolt is slidably shifted along the track 38 and spring 53 is compressed until crank arm l4 starts to pass its dead centre at which time spring 53 expands, and acts against stop lugs 55, causing the bar 13 to slidably and automatically retract and the crank arm 14 is driven to its upper position shown in Fig. 5, in which case the studs 41 of the bolt are shifted to the upper part of the casing and are in an unlocked relation with the eyes 56 of the keeper 5'! attached to the frame 58. It is apparent therefore that the driven bar I3 makes one complete cycle when the vbolt is shifted from its locked to its non-locking position. This is also true where the bolt is shifted from a non-locking position to its locked position in which case lower side 51 of bar l3 actsagainst wall 58, of guide opening 44 in lug (Fig. 4) to slide the bolt downwardly relative to the casing. During such operation, the bolt is slidably guided by bar 38 of loop 39, the spring 53 is first progressively compressedand after the dead centre 45 of the crank arm [4 is reached, spring 53 expands thus automatically retracting bar l3 which is limited in its retraction by stop lugs 55 striking lug 45 and hence the bolt 12 has been thrown to its locking position. A plate 60 serving as a closure, for the lock casing H is attached to the inner face of the door and screwsBl carried ,byplate60 hold the key controlled cylinder lock H) in its proper position. Rotatably carried by plate 60 is the slotted collar 62 to which is attached the driving means I! having crank arm 63. Tongue I8 of cylinder lock l9 interlocks with slot 64 of collar 62 (Fig. 2). By this arrangement the bolt l2 maybe controlled at the outside of the door and independently of the handle l5. Therefore with a properly bitted key inserted in key controlled lock l9, tongue 18 may be rotated. Hence driving member I1, is rotated and its crank 63 enters socket 29 fixedly attached to connecting recip- 65 rocable bar l3. If the key be rotated in one dimotion, the bolt is moved from an unlocked to a locked position and if rotated in an opposite direction the bolt is moved from a locked to a non-locked position. I Closure plate 60 is also provided with lugs 61 and the offset lug 68 which removably interlocks with the walls of the elongated opening 69 at one end of the lock casing and serves as meansto position the casing longitudinally of the plate 60 .75 while lugs 61 are receivable within the lock casing and cooperate with its peripheral rim 2'! to position the casing l l vertically of plate 60.

According to the invention illustrated in Figs.

4, 5, 7 and 8, the spring controlled connecting bar l3 may be readily assembled with plate 34 of 5 the bolt. In this connection spring 53 is threaded on shank or stem 5|]. Thereafter the latter is inserted on a bias into non-circular opening 5| of lug 52 (Fig. 8). Subsequently bar I3 is moved inwardly causing stop lugs 55 to compress spring 10 53 and stop lugs 55 enter into opening 69. Further movement of the bar l3 in the same direction causes notches ll thereof to receive lips 1|] thus permittingthe insertion of the reduced portion 12 of bar l3 into guide opening 44 of lug 45 15 at which time spring 53 is allowed to expand, thus shifting the body of the bar l3 to slidably interlock with non-circular guide opening 44 of lug 45. To remove bar l3 from plate 34, the former is moved to compress spring 53 until lips 20 10' register with notches H at which time reduced portion! I can be removed from guide opening 44 and stem 50 from lug 52.

Inthe form according to Figs. 11 and 12, the connecting bar l3 may be readily attached to 25 plate 34 by first inserting one end of stem 50 in opening 5| of lug 52. Thereafter the bar is manuallymoved to compress the spring 53 until stop lugs 55 are within opening 69 to permit shank 12' to enter non-circular guide opening 44 after 30 which manual pressure is removed permitting spring 53 to expand, thus causing shank 12' to be slidably moved in opening 44 until stop, lugs 55 abut lugs 45. If desired, bar 13 may be quickly disconnected from plate 34 by moving the bar 35 inwardly against spring 53. Thereafter shank 1 2 is tilted to be free of opening 44 after which stem 50 may be readily withdrawn. from opening 5| of lug 52. 1

Having assembled the connecting bar to the bolt, the latter may be quickly assembled with the lock casing. In this connection,: 100p.39.is first swung to its open position shown in Figs.

5 and 10. In such relation, the interior of the casing except for the rotatable crank l4 and the 45 swiveled arms 40 of the loop is free and clear of any encumberances (see Fig. 10) Therefore the bolt may be quickly positioned and inserted withinthecasing. To this end the studded block 35 is first slidably inserted in part within the gap 14 (Fig. 5) formed by the interconnecting

sockets

2l, 22, and 23 and wall 15 of the casing. 'Thereafter stud 28 is inserted into the bore of collar 33. Subsequently loop 39 is swung to its closed position, that is, its arms 40 enter grooves 31 of lugs 36. The bolt is now properly positioned and slidably locked in the casing. I

With the bolt and easing assembled, the casing may be readily attached to the closure plate 60 which is fastened to the inner surface of the door.

To this end, opening 69 in the peripheral rim 2! of the casing is first moved over offset lug 68 t removably interlock therewith.

Thereafter the upper and lower parts of rim 2'! are shifted towards the door to removably 65 straddle lugs 31 of the plate 60. It follows that the lock casing is now properly positioned in respect to the door. In such relation, transverse flange 24 is against edge face 25 of the door and upon insertion of screws 26, the lock casing is 70 fastened to the door.

When the casing is assembled and fastened to the door, the bolt I4 may be con-trolled by key 65 to rotate crank 63 which as previously set forth is utilized to actuate the connecting bar l3 for shifting the bolt vertically of the casing. Since with the present arrangement, the interior of the lock casing is free of the usual posts and lugs, the bolt may be readily positioned and set therein, the lock may therefore be readily assembled even without resorting to skilled operators and, since the bolt which may be in part or in'whole of a suitable durable stamping, it need not have an appreciable thickness and consequently the lock casing does not require appreciable depth, and it follows that a relatively thin although durable jimmy proof lock is provided.

As a further advantage, it should be noted that the lock casing l I if desired may be made from a single plate which is suitably stamped out in a single operation to provide the front wall 15 as shown and its peripheral rim 2! which embodies reduced portions or attenuated spacer means 16 defining alined recesses 11 for receiving upper and lower margins of the slotted rear wall 18 which is integral with the front wall 15. After wall 18 is bent over and against the spacer means 16, overhanging flange or-wall 24 which is integral with the body of the casing extends substantially normal to the rim 2'! and the marginal portions of the back wall 18 are welded to the rim 2! in any well known manner. Thus secured the reduced portions 16 provide closure means for the end sockets 2| and 23.

By the present arrangement, it is apparent that a dominant feature of the invention is realized in the provision of a simplified and improved lock which is characterized by a swingable member adapted to readily open or close. If opened, the bolt may be readily positioned in respect to the casing. If closed the swingable member can be conveniently shifted to interlock with the bolt to slidably guide the latter vertically of the casing and another feature of the invention is concerned with the provision of control means for actuating a reciprooable bar removably mounted on the bolt and adapted to shift the latter relative to the swingable member upon rotation of the control means.

Various changes may be made in details of construction and arrangement of parts without departing from the spirit of the invention or sacrificing any of the advantages thereof.
