Patented Jan. 36 191%.
Original application filed November 27, 1915, Serial No. 63,777. Divided and this application filed February 25, 1916. Serial No. 80,415.
To all whom itmay'concern:
Be it known that I, FENTON WRIGHT, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Locks, of which the following is a specification.
My present invention relates to new and useful improvements in looks, the primary object of my invention being the provision of a plug lock particularly adapted for securing closures to receptacles.
More specifically, this invention is a division of my copending application for a coin actuated clock bank filed November 27, 1915, and bearing the Serial No. 63,777.
In the above referred to application, I disclose a casing divided into compartments by a partition, one compartment inclosing a clock and the other constitutin a receptacle for coins inserted in the ban this latter compartment having a removable closure which is locked in place by my improved plug lock.
One of the objects of this invention resides in the provision of a plug lock which is carried by the closure and located within the casing or receptacle when the closure is in place and which has a locking member engaging a keeper carried by and inclosed 1n the casing or receptacle.
A still further object of my invention consists in providing a fixed support for a swinging locking member and a rotatable member having-a cam slot engaging one end of the locking member, whereby 1ts turnmg "will swing the locking member, and in the provision of tumblers for normally locking 7 the support and. rotatable member together, but so arranged that upon proper manipulation of the key the rotatable member .may be turned independently of the fixed-support and the locking member thereby swung-out of engagement with its keeper.
With these and other objects in view, my invention will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claims which are attached to and form a part of this application.
In the drawings: Figure 1 is a side elevation, partially in section, of a combined clock and bank casing having a removable closure secured by my plug lock; F1g. 2 1s a fragmentary central sectlonal view of the tion; Fig. 5 is a lock, showing a portion of the operating key in elevation; Fig. 3 is a view corresponding to Fig. 2, but taken at right angles thereto; Fig. 4 is a transverse section on the line 44 of Fig. 2, showing the lock in normal posisimilar view, showing the lock in released position.
Corresponding and like parts are referred to in 1 the following description and indicated in all the views of the drawings by the same reference characters.
Although it will be understood that my improved plug lock may be employed for any purpose for which it is adapted, it is constructed primarily as a means for locking a closure to the casing of a coin controlled clock bank and for this reason I have so illustrated it, omitting however, all of the coin controlled mechanism and clock mechanism which form no part of this present invention and merely showing the casing and its closure and the look. In the drawings, 10 indicates a substantially cylindrical caslng which may be provided with supporting feet 11 and which, intermediate its length, is provided with a partition wall 12 furnishing resultant chambers, one of which ordinarily incloses a clock and the other of which forms the coin reoeptacle of a coin controlled clock bank. This latter chamber is normally closed by a cap or closure 13,
the peripheral flange of whichis reduced in thickness at its free edge to seat Within the rear end of the casing 10 and to provide a stop'shoulder to limit its inward movement when applied. The inner face of the casing at one point is provided with a longitudinal groove 14 to receive a key or feather 15 formed lipon the reduced portion of the closure flange in order to insure application of the cap in identically the same manner under all circumstances. This capis secured in place by a plug lock mechanism, consti tuting my present invention and indicated as a Whole by the numeral 16 in connection with a keeper 17 carried by or formed upon the partition Wall 12 of the casing.
The body portion of the cap 13 is provided centrally with an opening 18 to receive the escutcheon 19 of the lock and this escutcheonis formed upon the outer end of a cylindrical lock housing 20 which projects at its other end in spaced relation to the partition wall 12 when the cap is in place, as best shown in Fig. l. The escutcheon 19 is formed centrally with a circular opening 21 to permit the rotation of the shank 22 of a key 23 and with diametrically disposed radial slots 24 extending into the opening 21 to receive the laterally extending key wards 25 which are preferably of unequal length,
socket 28 to receive the intermediate ward or centering ward 29 of the key. The open-,
ings 27 of the rotatable plug 26, at their free ends opposite the escutcheon, open into cylindrical sockets 30 in which are slidably mounted cylindrical pins 31 which are so proportioned that when the key is properly forced into the lock, their ends remote from the key will lie flush with that end of the rotatable plug 26 more remote from the escutcheon. Mounted within the lock casing 20 is a second but fixed plug 32 provided in one end with cylindrical sockets 33 in the inner ends of'which are seated light helical springs 34 which engage against drivers 35 m such a manner that in normal position of the lock the opposite ends of the drivers seat in the adjacent alined ends of the sockets 30 of the rotatable plug.
By forcing the key against the pins 31, the latter may be moved to force the drivers against the action of their springs until they lie wholly within the fixed plug 32 when the rotatable plug may be turned by turning the key. The fixed plug 32 is secured in the casing by any suitable means, such as the set screw 36 in such a manner that it can neither turn nor move longitudinally. This fixed plug is provided throughout its length with a longitudinal channel 37 and a looking lever 38 is pivoted intermediate its length in this channel, as shown at 39. This locking lever is-provided with a reduced cylindrical extension 40 at one end to receive a roller 41 which seats in a cam slot 42 formed in the adjacent end of the rotatable plug 26, one end of the cam slot being at the center of the plug and the opposite end opening through the peripheral face thereof. It will, therefore, be clear that turning of the rotatable plug in the proper direction will move that end of the lever received by it from a central to a peripheral position and will consequently, move the opposite end of the lever inan opposite direction. The opposite or outer end of the locking lever '38 terminates in an outwardly directed hook 43 which projects beyond the casing 20 and within the keeper 17. This keeper 17 includes an annular locking collar 44 which is either carried by or formed integrally with the partition wall 12 and which, at its free "ige, is formed with an inwardly directed peripheral locking shoulder 45, the outer face of which is beveled, as shown at 46, to facilitate application of the lock.
The foregoing description, taken in connection with the drawings, fully discloses not only the construction of my improved plug lock, but its operation and any further explanation is, therefore, believed to be unnecessary. Obviously, many changes in the details of construction may be made without affecting the primary principles of operationof my device and I therefore retain the right to make any changes within the scope of the appended claims, without in the slightest degree departing from the spirit of my invention.
Having thus described the invention, What is claimed as new is: J
1. In a lock, the combination with a keeper having an inwardly directed locking shoulder, a plug lock housing in alinement with the keeper, a rotatable key operated plug in the lock housing having a cam slot in one end, and a locking lever pivoted intermediate its length and engaging at one end in the cam slot and formed at its other end with a hook to engage the locking shoulder.
2. A plug lock including a lock casing, a fixed plug in the casing formed with a slot, a lever pivoted intermediate its length in the slotand extending beyond the casing and being formed with a hooked'terminal for engagement with a keeper, a rotatable plug in the casing adapted when rotated to cause swinging of the lever, and means normally locking the rotatable plug to the fixed plug and releasable by application of a key to the rutatable plug to permit turning of such p 3 2A lock including a casing, a fixed plug mounted in the casing, a rotatable plu mounted in the casing and abutting one end of the fixed plug, the abutting ends of the plugs being formed with alined sockets, spring pressed drivers normally seating partially' in the sockets of one plug and partially in the sockets of the other, pins seating 1n the sockets of the rotatable plug and movable when engaged by the wards of a key to force the driversout of the sockets of the rotatable plug, whereby the latter may be turned, the rotatable plug being formed with a cam slot and the fixed plug with a longitudinal slot, and .a locking lever pivoted in the longitudinal slot of the fixed plug and seating in one end of the cam slot of the rotatable plug, whereby turning of the rotatable plug will swing the lever, the free end of the lever extending beyond the casing and terminating in a hook.
