LOCK.

Application med December 15', 1925. semi 1w. 75,4s5.

Vl`his invention relates to locks for doors and the like ot the type wherein a tongue or pintle is arranged for sliding movement in aprojection extending from one end of the lock casing to have movement in a direction transversely oit the lock casing by a carrier therefor arranged in the body of said easing imparted thereto by means of a hand operated knob or a key actuated means as disclosed in the prior Patent No. 1,215,470, granted to me February 13th, 1917, and itis the priniary olijectot` the present invention to provide an improved construction and arrangement ot look casing, bolt carrier and actuating means therefor to not only greatly eheapen the cost of manufacture and :facilitate the assembling oit" the lock, but also to increase the etliciency thereof.

In locks for doors and the like of the permutation type wherein the bolt is `adapted to be actuated or movedto locking and unlocking` position by key actuated means from the outside of the door, and the bolt being operated from the inside of the door bya hand operated knob, and particularly Where the doors serve as a barrier for access to a building, such as a store, a method in surreptiously removing goods therefrom is to gain access to the store as through a Window or otiierwiseand then release the door from the inside by actuating the lock bolt by the handwoperated knob, when the goods are taken trom the store or other lace to a conveyance exterior ot the buil ing. To provide against this key operated means have been provided to actuate the lock bolt both from the exterior and interior of the door.

It a tur-ther object ot' the invention to provide a lock embodying' bolt actuating means operable by key actuated means and a hand knobl the means operative by the key not only actuating the bolt to move the bolt to lockingv and unlocking position but also being operative to set the bolt actuating meansy to `lock the bolt actuator against manipulation by the hand knob when the bolt is in locking position and thus prevent the actuation of the lock from the inside of the door to release the same when the bolt has been moved to locking position `by the key operated means 'trom the exterior of the door, or to set the bolt actuating means with the boltin locking position so that the bolt actuating means may be actuated bythe hand knob to move the holt` to locking and unlocking position from the inside.

Other objects and advantages will hereinafter ap ear.

The embodiment of the present invention is shown for use in connection with a door hingedly supported to swing on a vertical axis at one longitudinal edge, but it will be obvious that the application of the invention is not limited to such use, the door being indicated at 14 and the door frame at 15. The lock casing, designated in a general way by C, is of hollow structure, of rectangular shape and open at the back with a convexedly formed projection 16 extending from one end as a continuation of one side and extending for substantially one-half the width of the lock casing and opening into the lock casing, as at 17, and having an opening in the underside, as at 18, for a purpose to be hereinafter described. The opening in the back of the casing is closed by a'plate 19 secured thereto by engaging a lug 20 projecting from one end of the plate under a shoulder formed in the end wall of the casing adjacent theprojection 16, as shown at 21, and the other end resting upon a boss 22 at the end of the casing opposite to the projection 20 and secured to the casing by a screw 23 iengaging a recess in said latter end of the closure plate and threadedinto the boss 22.

- The4 bolt is inthe form of a tongue or pint-le 24 integral with a frame 25 and whereby'it is mounted in the casing to engage in the casing projection 16 to extend in a plane parallel with the length of the door and have movement transversely of the lock casing to be projectedfrom the projection opening 18 and drawn thereinto by the movement of its carrier frame. The bolt carrier frame has a. rectangular portion 26y whereby it is slidably mounted upon a rod 27 engaging in perforations in the opposite longitudinal members of said frame, said rod being mounted at its ends, as at 28, in the legs of a U-shaped member 29. The portion of this U-shaped member between the legs is of a length substantially the width'ot the casing and is engaged in the casing to lie contiguous to the inner surface of the front wall thereof with the legs ext-ending to and of a length substantially the same as the width of the casing, the terminals `of the legs being undercut, as at 30, to be engaged in opposite recesses 31 in the closure plate whereby said Ushaped member is held against lateral movement. Oppositely curved portions 32 extend from the end of the rectangular portion of the frame 26 opposite to the bolt 24, the inner surface of said extended portions 32 being in the arc of a circle whose center is the axis of an actuator for the bolt carrying iframe in the form of an arm 33 fixed on a tubular member 34 rotatably mounted in the front wall of the casing and on a line extending longitudinally andV centrally through the casing. The outer ends of said curved portions are connected, as at 35. In assembling the bolt in the lock` casing the bolt carrying i frame 25 is `first mounted on the rod 23 and the lattersccured in the legsV of the U-shaped member 29. In this condition the Vbolt end of the frame is canted downwardly and passed through the opening 17 between the projection 16 and lock casing when the opposite end is readily engaged over the actuator 33 with the U-shaped member 29 in contiguous relation to the front wall of the casing. The closure plate is then secured to the casing as hereinbefore described when the bolt frame may be manipulated through the actuator 33 to move the boltV to locking position by projecting it from the opening 13 of projection 16, or to unlocking position by drawing the bolt into the .lock projection 16. Vhen the bolt is moved to locking position the actuator 33 through the rotation thereof rides along the upper curved portion 32 and onto the lower of vsaid portions, and vice versa when the bolt is moved to unlocking position. The bolt is retainedv in unlocking position by resilient means comprising a strand of resilient wire 36 wound intermediate its ends around av pin 37 fixed in the casing with one end engaging affixed abut ment 38 vwhile the opposite end 39 slidably engages with the actuator. The lock is scf cured to the door by screws 40 passing through the lock casing and openings 24 at the end opposite to the bolt engaging projection 36 and threaded into the door` and bv angles to the back 'of the casing, said flange being adapt-ed to engage at the edge of the door with the screws 42 extending into said edge of the door. The lock is secured on the inner side of the door and the bolt is adapted to be thrown into and out of locking position by a hand knob 44 fixed yto the end of the carrier 34 for the bolt actuator 33 extending through the front wall of the casing. To opera-te the bolt actuator from the outer side of the door key operated means is provided. This may be of any conventional form of permutation lock mounted in an opening in the door coaxially with the actuator 33 and including a tumbler carrying cylinder 45 and slotted barrel 46 for the engagement of a key 47, the key barrel being held against rot-ation when the keyv is removed by tuinblers as is usual. The key barrel is operatively connected to the actuator 33 by a bar 48 secured at one end to the key barrel and the opposite end enga-ging a correspondingly formed opening in a carrier 49 rotatably mounted in the closure plate for a dog 50. The dog 50 is mounted on the end of the carrier 49 extended through the closure plate within the casing by engaging nibs 51 extending oppositely and inwardly from a collarportion of the dog in a transverse slot in said projecting portion of its carrier and then peening the material of the carrier over said collar portion of the dog. An abutment in the 'lorm of a lug 52 projecting from the side of ithev actuator arm 33opposite tothe dog 50 and eccentric to the axis of the actuator is arranged in the path of movement of the dog and is engaged by the dog as movement is imparted thereto through its connection with the key barrel 46 as the latter is rotated by a key to actuate the bolt carrier frame and move the boltto locking and unlocking position by the key.

As stated, itis an object of the invention to provide a construction of lock wherein the bolt is adapted to be manipulated to move it to locking and unlocking position by either a hand knob from the inner side ofthe door, or by key operated means from the outer side of the door, and the key operated means being adapted to be set to prevent the actuation of the bolt actuator by the hand knob when the bolt has been moved to locking position, or set to permit the actuation of the bolt actuator by the hand knob when the bolthas been moved to locking position by the key operated means. This result is produced by the arrangement oi operatively connecting Vthe key operated means to the bolt actuator through the dog 50 and the abutment 52 on the actuator.

The normal position of the parts with the bolt in unlocking position is as shown in Figures 3 and l0 with the actiuitor 33 eX- tending upward from its carrier and the dog 50 engaging at the right side ol' the actuator abutment 52. In this position the bolt actuator may be actuated at will to move the bolt to either locking or unlocking position by the hand knob. llVhen the bolt actuator is actuated by the key operated means to actuate it to move the bolt to locking position the dog engages with the actuator abutment 52 thereby moving the actuator to the left as viewed in Figure l0 to the position shown in Figure 1l. The dog is retained in this position by the tumbler pins co-operating with the key barrel when the key is withdrawn with the result that the bolt actuator is held against actuation by the hand knob 44. -When the dog is in the position shown in Figure 11 a complete revolution will have been given to the dog and the key is in positionto be Withdrawn from the key barrel. To permit of the actuation of the bolt actuator by the hand knob after the bolt has been moved to locking position by the key operated means, as just explained, reverse movement is imparted to the dog by the key from the position shown in Figure ll to that shown in Figures l2 and 13 so-that the dog engages at the side of the abutment 52 opposite to that shown in Figure 11.`

To perform the function o'f latching or locking the door the bolt tongue or pintle 24 (2o-operates with a keeper 53 fixed to the door frame (Figures l2 and 8). This keeper is of rectangular shape in cross section to `embracethe corner formed by the edge and one face ot the door frame and secured thereto by screws 54 engaged in openings in both angular portions of the keeper. as shown in Figure 8. A hollow lug 55 projects from one angle portion of the keeper to project from the door frame and has an opening 56 to the interior thereof. The keeper is of a length substantially the same as the Width of the lock casing and the projecting lug 55 is of a length substantially one-halt the keeper and arranged to fit in the angle portion Vformed by the casing projection 16 and shaped to conform to said casing projection. .Art-the end of the keper opposite to the projection lug there is provided a lug 5f? between which lug and the projection 55 the projecting portion 16 of the casing adapted to engage with thedoor in closed position. This lug 57 prevents any cantine movement oit- Vthe door in an attempt to distort the door in its frame when closed to litt the bolt from the keeper lug 55 and thus open the door.

By the construction and arrangement of lock "and keeper and the mountingr of the same upon the door and door frame it will be obvious that it will be impossil'ile to remove the lock or the keeper from the interior of the door'with the object 0f openingthe door since the lock'is securely held to the door by the screws engaging the openings in the lock flange 43. Also that access cannot be had to the screws 54 engaged in openings in that lll() Having thus described my invention, Iy
