Application filed June 17,

To all whom it may concern:

Be it known that I, JAMES E. PHILLIPS, a citizen of the United States, and a resident of the city of New York, borough of Main hattan, in the county and State of New York, have invented a new and Improved Look, of which the following is a full, clear, and exact description.

This invention relates to locks and pariii ticularly to what are termed burglar-proof locks wherein means are provided for preventing jimmying or otherwise forcing the bolt o-r keeper out of the correct position.

The object of the invention is to provide a 13 strong and very simple construct-ion which is very difficult if not impossible to open without the proper key. 7

Another object of the invention is to provide a lock wherein the keeperis offset in 2-) order to permit the lock casing to be positioned so that an instrument cannot be forced into engagement with the bolt.

A further object of the invention is to provide a lock in which the bolt may be posi- 2., tively locked in an outer position by a key m) ing an embodiment of the invention.

Figure 2 is a rear view of the structure shown in Figure 1, the bottom plate of th lock casing being removed.

Figure 3 is a view similar to Figure 2 but showing the bolt retracted and the keeper removed.

Figure 4 is a fragmentary sectional view through a door and jamb with a lock embodying the invention shown applied thereto,

said lock being shown in horizontal section.

Figure 5 is a detail perspectve view of a bolt protecting shell embodyingcertain features of the invention.

Figure 6 is a fragmentary sectional view through Figure 4: approximately 011 line Referring to the accompanying drawings by numeral, 11 indicates an ordinary doo-r j amb and 12 a door coacting therewith. A

keeper 13 is secured to the door jamb by any suitable means, as for instance, screws 14;. This keeper is provided with an offset shoulder 15 over which part of the casing 16 extends. The keeper 13 is provided with an .apertured wall17 for receiving the end of 1922. Serial No. 569,059.

bolt 18, said wall having a return section 19 in order to produce a nice appearance. By providing the offset shoulder 15, no one can insertan instrument through the opening 20 and engage the bolt 18 for forcing the same back to an unlocked position; I

The casing 16 is secured to the door 12 by screws or any other desired means and is provided with hooks 21 and 22 adapted to move over the laterally extending projections or flanges 23 and 24 extending from the keeper 13 as indicated in Figure 1. This arrangement of hooks and associated parts prevents the door from being jimmied or forced apart by an. instrument while the bolt 18 prevents the door from swinging on its hinges when the bolt is in an outer or locked position as shown in Figure 1.

The casing 16 is provided with a covering plate 25 of any desired kind held in place in any desired manner, as for instance, by the screw 26. The bolt 18 is intended to reciprocate in the casing 16 in such a manner that one end may project therefrom as shown in'Figure 4 when the parts are in a.

locked position. This bolt is provided with a slot or opening 27 through which the post 28 extends, said post receiving the screw 26 while acting to limit the outward movement of the bolt. A. spring guide rod 29 extends loosely through the post 28 and supports and guides the spring 30 which tends to force the bolt to its outer or locked position. The inner end of the bolt 18 is provided with an arc-shaped section 31 having a projection 32 co-acting with the rollback 33 which tumbler is rigidly secured to the shaft 34, said shaft extending through the casing 16 and having rigidly secured thereto a thumb member 35 whereby it may be readily turned at any time. A loosely mounted sleeve 36 is arranged on the shaft 34 be tween the thumb member 35 andthe casing 16 so that if an unauthorized person should attempt to withdraw the bolt 18 by passing 'a cord between the thumb member 35 and the casing and then acting to rotate the shaft 34:, said action will not have any effect on the bolt by reason of the freerotation of the collar or sleeve 36. A collar 37 is provided and loosely mounted ina bore in shaft 34;, said collar having a tumbler 38 and a key opening 39 which key opening is adapted to receive a key ora projecting member 40 from the locking mechanism 41. This locking mechanism may be of the usual tumbler type with the rotatable barrel and the member 40 may be rigidly secured to the barrel so that when the barrel is rotated by the correct key the sleeve 37 will be rotated and the tumbler 38 actuated. This tumbler is actuated merely to lock the bolt 18 against withdrawal by reason of the fact that the tumbler 38 moves into the depression 42 and thereby acts as an abutment for preventing the return movement of the bolt even when an authorized person rotates the thumb mem ber 35.

In order to provide means for making it more ditlicult for anyone to force the bolt 18 to an unlocked position, a guarding member 43 is provided, said member having a plate or section 44 extending across the bolt 18 and in position to be engaged by any instrument forced through the opening 20, said plate or section having depending side walls 45 and 46 which straddle the bolt 18. The wall 46 extends to the rear a short distance and is provided with a notch 47 adapted to receive the locking lever which is pivotally mounted at 49 on the bolt 18. The arm 50 of locking lever is rounded on one surface so that when the bolt is withdrawn through the action of the rollback 33, arm 50 will pass by the post 28 but in case an unauthorized person should force an instrument through the opening 20 and attempt to force back the member 43, the extending section of wall 46 would cause the locking lever 48 to swing on its pivot 49 swinging the arm 50 against post 28 and, thus, resist any appreciable movement of member 43 as well as lock the bolt 18 against movement until the parts are restored. As the bolt moves outward toward a locked position, it will carry with it the pin 49 and cause the arm 50 to slide past the post 28. The lever 48 cannot swing by reason of the fact that the post 28 will not allow the arm 50 to swing until it has passed the post and, consequently, the member 43 will move with the bolt to the position shown in Figure 4. In this way, two features have been presented to prevent forcing the bolt 18 back to an unlocked position, namely, the shoulder 15 and the member 43. The tumbler 38 will also act as means for preventing the return of the bolt.

\Vhat I claim is 1. A look of the character described, comprising a keeper having an offset portion presenting a shoulder, a lock casing adapted to be connected with a door and overlap said keeper to lit into said shoulder, said keeper having an opening for receiving a bolt, a reciprocating bolt arranged in said casing, means for actuating said bolt to cause the same to be projected into said keeper and be retracted therefrom, and means moved by the bolt to form an impediment between the bolt and the offset portion of said keeper adjacent said shoulder.

2. In a lock of the character described, a casing, a reciprocating bolt arranged in said casing. manually actuated means for shifting the position of said bolt, a guard member overlapping part of said bolt, said guart member having a notch, and a locking lever formed with an arm fitting into said notch, means for mounting said locking lever on said bolt, and means co-acting with said locking lever for preventing the reciprocation of said guard member independent of the bolt.

3. In a lock of the character described, a 'asing, a lined post arranged in the casing, a bolt having a slot through which said post extends, a spring for normally moving said bolt in a projected or locked position, a manually actuated member for retracting said bolt, a guard member straddling said bolt and provided with an extending section, said extending section having a notch, a locking member formed as a bell crank lever, means for pivoting said locking member on to said bolt so that one leg will project into said notch and the other leg will extend parallel to and near said post.

4. A lock, comprising a keeper having a plate adapted to be secured to the face of a door jamb and a bolt receiving portion formed with a portion off-set for presenting a shoulder extending from one end of the keeper to the other, said shoulder extending an appreciable distance back from the edge of said jamb, a casing adapted to be, connected with a door, said casing overlapping said plate and engaging said shoulder for its full length, said bolt receiving portion having a hooded part to receive a bolt and a pair of oppositely extending lugs projecting from said hooded part, said casing having hooks adapted to interlock with said lugs when the casing is engaging said plate, a reciprocating bolt arranged in said casing, and means for actuating said bolt to cause it to be projected into said keeper and be retracted therefrom.
