LOCK.

`Specification of Letters Patent.

Patented NOV. 26, 1918.

Application filed December 27, 1917. Serial No. 209,069.

State of New York, have invented new and useful Improvements in Locks, of which the following is a specification.

This invention relates Ito key-operated locks, the invention being more particularly related to key-operated locks adapted for use in connection with money bags, mail bags and other receptacles. Y

A main obj ect ofthe invention is the provision of a novel safety lock of this type comprising an elongated casing provided with alined tubular elements projecting one into the casing and one outside of the casing, the latter being adapted to be connected with the mouth of a money bag or receptacle for the appropriate insertion and discharge of articles, there being within the casingl a slight space between the tubular elements for the operation of a key-operated closing plate so formed and arranged with respect to the casing and tubular elements as to prevent picking.

Another obj ect of the invention is the combination in a lock of this character of a key barrel rotatable in a keeper, boththe key barrel and the keeper being provided with locking pins requiring a special key for their manipulation in order to effect the unlocking action and the withdrawal of the closing late. p Another object of the invention is the provision of a lock having the foregoing features, which is simple in construction, easy of assembly, comparatively inexpensive to manufacture and which is durable and effl- Cient in service.

lVith the foregoing objects in view and others,l the invention resides in the details of construction and in the arrangement and combination of parts hereinafter described and shown in the accompanying drawings, forming a part of this specification, and in which 2- v Figure l is a View in perspective of the exterior of the lock.

With more particular reference to the accompanying drawings, thefnumeral 15 is employed to denote a flat elongated casing section or plate having preferably rounded ends, and cast with a tubular portion 16 projecting laterally from the underneath side thereof, providing through the section a circular opening 17, kras best shown in Fig. 4. Between the tubular element 16 and the opposite rounded end and midway of its width, the casing 15 isalso provided with a circular opening 18 for the reception of the keeper and key barrel, as will be later described. The coperatingcasing section comprises a similar elongated plate 19, cast with an integral` iange `or wall 2O on one side, preferably of the same size as the section'15so that when the sections are assembled, the outer periphery of the iange 20 lies `flush with the peripheral edge 155 of lthe casing 15, as best illustrated in Fig. 1, the said casing section 19 also being cast with a tubular portion 21; providing a circular opening 2l through the plate 19. The tubular portions 16 and 21 are of the same diameter in order to register as will presently appear, but they may differ in length, the-exact length of the portion 16 depending' on the width of the wall 20, while that of the portion 21 may depend on the character of the receptacle to which it is to .be attached'. lVith the tubular element l21 isA also cast' an outwardly projecting Hange 22, around and upon which may be secured in, any suitable manner the mouth of a bag-or receptacle as 23.

In order tosecure the casing sections l5 and 19 together, I. .preferably cast upon the underneath side of the casing section 15, that is to say, upon the same side from which projects the tubular Aelement -,16, suitable posts as 24, 25 and 26, the same being spaced inwardly from the peripheral edge 15, a distauee equal to the thickness of the flange 2O of the easing section 19, there being also cast with the periphery of the portion 16, a lug 27 similarly spaced from the edge 15. Each of these posts is provided with a screw threaded opening as 28 with which registers suitable screw threaded openings as 29 provided in the flange 20, which openings are adapted to receive threaded screws as 30 whereby the sections are secured rigidly together in the position desired with the tubular portion 16 projecting into the casing in register with but not quite meeting the tubular portion 21. rlhus I provide a continuous opening through the assembled sections, through which articles may be dropped into the receptacle and also discharged therefrom in an obvious manner.

To operatively maintain the key barrel, I provide in the present embodiment of the invention, a keeper 31 having a head slightly larger in size than the circular opening 18, which head is provided verticallyv tuerethrough with an opening 32 slightly smaller in diameter than said opening 18, said head on one side being provided with a collar 33 contiguous with the walls of the opening 32 and adapted to lit within the opening 18, and to extend part-nay therethrough. This keeper is also formed with the oppositely projecting ears 34, having eyes 35 formed therein to register with threaded openings 36 provided in suitable posts 37, preferably east with the plate 15. CScrews as 38 '12), which engage the eyes 35 and 36, are employed to secure the keeper rigidly in position with its integral elongated body portion 39 projecting toward the portion 16. In this elongated body portion is provided spaced apart circular cavities as 40 in communication with the opening 32 thereof. Seated within these cavities are push springs 41 adapted normally to urge outwardly pins as 42, also slidably fitted therein for a purpose as will presently appear.

rlhe key barrel 43 adapted rotatably to fit the opening 32 of the keeper, is provided at one end with a flange 'i-l, which seats upon the end of the collar 33 Within the opening 18, and which is of such thickness that the outer or face end of the barrel lies flush with the outer face of the plate 15, the barrel also being provided with a key slot 45 extending longitudinally therethrough from a point near the axial center to the circumference, as best shown in Fig. 8. Upon the inner end of this key barrel is formed a lug 46, projecting beyond the inner side of the keeper 31 to iit in the longitudinal slot 47 provided in the tumbler 48 (Fig. 7).

There is provided in the heel of the key barrel 43 circular transverse cavities 49 which communicate with the key slot 45, it

being noted in this connection that these cavities are of a diameter greater than the key slot is wide and that the same extend a distance through the walls of the key slot forming confronting arcuate cavities as best shown in Fig. 10. lVithin these circular cavities are seated other pins as of unequal length. When the barrel 43 is turned th the heel thereof in proper position with relation to the body element 39 of the keeper, the cavities 49 are brought into alinement with the cavities 40, so that the pins 42 may enter the cavities 49 pushing the pins 50 forwardly into the key slot. In this manner the key barrel is locked with its keeper against rotation.

The pins 50 are made of unequal length to tally with the special unequal projections on the. barrel key, which under this construction is preferably of the cylinder type. rilhe key with its projections added to the lengths of the pins 50 equals the diameter of the key barrel. 1n view of this arrangement, it will be obvious that when the key is inserted in the key slot, the projections on the key will actuate the pins 50 forcing the keeper pins within the keeper, so that the key barrel may be turned with the turning of the key.

The tumbler 48 is further secured to theinner end of the barrel by screws as 51 which pass through eyes as 52 of the tum bler and are threaded into registering threaded eyes as 53 provided in the barrel. Formed integral with the narrowed forward end of the tumbler 48 is a laterally projecting pin 54, which engages a diagonally disposed longitudinal slot 55 provided in the elongated closing plate or tongue 56, which is of such length that when the key barrel is locked with its keeper, it extends beyond the tubular portions 16 and 21 and also that when the barrel is unlocked from its keeper and turned partly around, as shown in dotted outline in Fig. 2, it clears the openings through said members.

It will be noted inv this connection that the ange 20 of the casing section 19 is wider than the tubular portion 16 for a dist-ance equaling the thickness of said closing plate 56. so that said plate, sliding upon the inner side of the section 19, is adapted snugly to fit between the adjacent ends of the tubular portions 16 and 21, completely closing the opening therethrough in such manner that the closing plate cannot be engaged by any instrument from the outside for its reverse movement. The confronting walls of the flange 2O serve as guides for the closing plate to operatively maintain it against displacement.

From the foregoing description, taken in connection with the accompanying drawings, the operation of my lock will be obvious. By inserting the proper key in the key slot, the keeper bolts are pressed in as described, whereupon the barrel may be turned, which movement is accompanied by the turning of the connected tumbler, the pin` 54 of the tumbler sliding to the opposite end of the slot 55 thereby permitting the closing plate to be withdrawn to the opposite end of the casing, as shown in dotted outline in F ig. 2.

Having thus described my invention, what I claim iszl. A safety lock including a casing provided with registering openings, a plate slidably disposed within the casing and adapted to be extended to positively close communication through said openings, an element r0- tatably secured in the casing, means for locking the rotatable element, a tumbler operated by said rotatable element, and means connecting said tumbler with said plate for actuating the latter and for maintaining the same immovable when said rotatable element is locked.

2. A safety lock comprising assembled casing sections having registering openings, a plate slidably disposed within the sections and adapted to be extended to positively close communication through said registering openings, a keeper device, an element rotatable therein, means for locking the rotatable element with the keeper device, a tumbler voperated bythe rotatable element, and a connection between said tumbler and said plate for actuating the latter and whereby when the rotatable element is locked the said plate will be held locked in extended position.

3. A safety lock for receptacles comprising a. casing with an outer projecting tubular portion and an inner projecting registering tubular portion terminating spacedly from the end of said outer one, a plate slidably disposed within the casing and adapted to close communication between the yregistering tubular portions, a keeper device tted in the walls of the casing, a barrel rotatable therein, means for automatically locking the barrel with the keeper in one position, a tumbler connected to and operating with the barrel, and a connection'between the tumbler and said plate to operate theV latter, and also to maintain the same locked in extended position when the barrel is locked with the keeper.

4. A safety lock for receptacles, comprising combined sections each cast with a tubular portion7 one portion projecting exterior of the casing and the other within the same,

the said tubular portions being arranged with their ends in registry to permit an article to be passed through the combined sections, but with a space intervening between said registering ends, means combined with the exteriorly projecting portion for receiving an article, a plate slidably disposed within the casing and adapted to close communication between the registering tubular portions, said plate being of such size as to be guided by the sides of the casing, and key operated mechanism combined with the casing and connected with said plate to operate said plate and to hold it locked when in closed position.

5.` In a safety lock for receptacles, an elongated casing having one side formed with an exteriorly projecting tubular portion adjacent one end thereof and its opposite side formed withan interiorly projecting tubular portion in re 'ster with the inner end of said first tu ular portion but spaced therefrom, an elongated plate slidably arranged in the casing, akeeper tted in the casing side having the interiorly projecting tubular portion, posts combined with the casing for securing said keeper, a key operated barrel arranged in said keeper, a tumbler carried on the inner end of said barrel, and a pin and slot connection between said tumbler and said plate whereby when the barrel is turned into one position the plate will be extended and held locked completely closing communication between the registering tubular portions and when turned into another position the plate will be withdrawn permitting communication between the tubular portions, and means for automatically locking said barrel with said keeper when the plate is extended.

In testimony whereof, I have signed my name to this specification.
