SPECIFICATION forming part of Letters Patent No. 725,381, dated A ril 14, 1903.
Application filed Octo ber 11,1902. Serial No. 126,882. (No model.)
To all whom it mag concern:
Be it k'nownthat I, HARRY P. TOWNSEND,
a citizen of the United States, an'd'a resident of New Britain, in the county of Hartford and State of Connecticut,have inventeda new and useful Lock, ofwhich the following isa specification.
My invention relates more especially to that class of locks in which a number of tumblers to are brought into registering position by the hands of the operator to allow movement of the bolt, this class of locks being more commonly known as combination-locks.
The objects of my invention are to produce a lock of this class which may be easily and quickly manipulated, one which is secure against discovery of its combination, one
which may be operated without visual aid,
and one whose tumblers are-automatically 2c returned to their locking 'positionsafter the bolt has been moved torelease the door or look by opening the receptacle. 'A'rorm of device by means of which these objects may be attained is illustrated in'the accompany ing drawings, in which- Figure 1 is a View in front elevation of the frame and of a door closing a receptacle and having my improved lock applied thereto, the door being closed and the operating pins located in their normal position. Fig. 2 is a view of the upper portion of the'door and frame, the door being closed and the operating-pins located in position to permit mo've-- ment of the bolt to release the door.- is a rear view of the door and frame shown tion. Fig. 4 is a rear view of the upper part of the frame and door, the latter being closed and the latch-carrier thrown back. Fig. 5 is a detail view showing the rear of the upper portion of the door, the parts being in the position assumed when the door is opened and the latch-carrier being removed. Fig. 6 is a rear view of the upper portion ofthe door and frame, the former being closed and the latch-carrier and tu mbler-plate being removed. Fig. 7 is a detail view in cross-section through the door and frame and the lock mechanism on the dotted line at a: of Fig. 3. Fig. 8 is a detail side view of oneofthe tumblers. Fig. 9 is a detail end view of the latch.
.cated. eachrecess isadapted to contain two tum- 75 in Fig. l and with the parts in the same pbsi: 1
While my improved look is' adapted to any device for closing the opening to a receptacle, it is especially applicable to the'forni of lockbox commonly'employed in post-offices, and for this reason I have selected this-form of receptacle I in connection withwhich to illustrate. the invention.
In the accompanyingdrawings the numeral 1 denotes the frame ofthe opening to the receptacle, and 2 the door closing said opening. The door is provided with openings or slots 3, which may be of any number desired and through which project operating-pins 4. The
.inner face or back of the door is providedwith retaining-studs5, one of which, 6, is in the formof a screw and is slabbed off on one .side to permit the removal of certain parts held by the studs. These studs also provide slideways for portions of the mechanism. A tumbler holder or plate 7 isheld by the studs 5, and this holder is provided with tumblerrecesses 8, in which the tumblers 9 are 10- In the form of holder herein shown blers; but these re'cessesmay have any number of tumblers desired, as it is obvious that the improved lock is capable of the employment of any plural number of tumblers. Eachtumbler preferably consists of a rectangular- 8o shaped disk, from one face of which projects the operating-pin 4, and located on the otherface of which is-a locking-stud 10. Retaining-springs-11 are employed'for the purpose.
f'of holding the tumblers in proper position. Int-hefo'rm shown each tumbler is provided tumblers-that is, the livetumblers-are those which must be moved into such position that 5 the latch plate or bolt may be thrown back, and the dead-tumblers are those which require no movement to enable this operation to be done. The notches in each of the tumblers are so located that the bumps in the no springs will lie in notches, whether the tumbler be a live ora dead tumbler, and this construction renders the feeling out of the combination a difficult matter, as the springs offer an equal resistance to the moving of all.
the tumblers, so that the force required to move each tumbler is practically the same. By reversing any tumbler it may be created live or dead, depending upon its condition before being reversed.
A latch or bolt plate 14 overlies the tumbler-holder 7 and has a free sliding movement underneath the heads of the studs 5 6. This latch-plate is provided with T-shaped openings 15, into which the locking-studs 10 from the tumblers project. The studs on the live-tumblers have a movement in the crosswise part of the T-shaped slot and are brought into a position opposite that part of the slot corresponding to the stem of the T. when all the locking-studs have been brought into this position, the bolt is thrown backward by the action of the spring 16. It will be noted that a like movement of the deadtumblers will place thelocking-studs in such position that the bolt cannot be moved, so that only the live-tumblers must be moved in order to enable the latch-plate to move to throw the bolt or latch.
A latch orbolt 17 is mounted on the latchplate and is adapted to enter an opening or recess in the frame to hold the door in its locked or closed position. A latch-stud 18 projects through a slot 19 in the latch, allowing the lock an independent movement of the latch-bolt. It will be noted that the latch or bolt is moved from engagement with its socket in the frame only by the movement of the latch-plate and that neither the plate nor the latch can be moved from outside of the openingthat is, there are no means.
on the outside by which an extra pressure may be brought to bear on the tumblers through the latch-carrier to enable any one to determine which one of the tumblers will be required to be moved in order to allow movement of the latch-plate. The latch-plate is also provided with a cam projection 20, arranged to engage a cam-lug 21 on the doorframe. As the door is opened this cam projection 20, striking the lug 21, throws the plate in such position that the live-tumblers may be again returned to their normal location assumed when the parts of the structure are in their locking position.
A tumbler-returning plate 22 underlies the tumbler holder or plate 7 and has a free sliding movement. This tumbler-returning plate is provided with guide slots 23, receiving guide-studs 21- from theback face of the door. These studs and slots are so arrangedthat as the plate is moved longitudinally it will also have a lateral movement imparted to it, the two movements constituting a diagonal movement of the plate. This tumbler-returning plate is also provided with triangular-shaped holes 25, through which the operating-pins 4: extend. The tumbler-returning plate has on its back edge a plate extension 26, which is adapted to strike the edge of the door-frame and as the door is closed throw the plate toward the opposite edge of the door against the force of the returning plate-spring 27. This holds the plate away from the tumblers when the door is closed and allows each of the tumblers a free movement except for the pressure of the tumbler-retaining springs.
lVhile I have shown the spring 27 as a means of forcing the tumbler-returning plate 22 into position to return the tumblers to place, it is obvious that means other than a spring may be employed and yet come within the scope of the invention, and I do not desire nor intend to limit myself to this form. It is also obvious that different parts of the structure maybe variously changed and m odified without departing from the invention, and such changes or modifications are contemplated byme.
A cover-plate 28 is employed for covering the parts of the look.
It will be noted that the latch-head is composed of a piece of metal cast or struck up to form the slanting front edge of the latch and the side walls being formed without seam or joint and the back being left open.
The operation of the device is as follows: The door being closed and the parts in normal position, as shown in Figs. 1 and 3, the tumblers a, b, c, and d are arranged as the live-tumblers and must be operated to allow the door to be unlocked. These letters are applied to the pins and studs as well as to the tumblers for the sake of clearness. The operating pins having been pushed down, as shown in Fig. 2, the locking-studs are brought into the position shown in dotted outline in Fig. 3. As soon as the last stud has been brought into this position the latchplate 14: is thrown back under the force of the spring 16, and the door is thrown partly open by the force exerted by the spring 27 through the tumbler-retaining plate 22 and its extension 26. As the door is now pulled open, as by means of the knob 29, the cam projection 20 striking the lug 21 on the door-frame throws the latch-plate 14. forward into the position shown in Fig. 3. Thisopening movement of the door has released the projection 26 from contact with the door-frame, and the tumblerreturning plate is free to act under the influence of the spring 27, except that for the fact that the lower edges of the triangular holes 25 have been forced against the operatingpins 4, which in turn are held by the lockingstuds 10, located in that part of the T-shaped openings corresponding to the stem of the T in the latch plate. As above stated, this latchplate being thrown backward the spring 27 is free to act, and the tumbler-returning plate 22 is thrown back, the lower edges of the triangular-shaped slots coming against the pins on the livetumblers and returning the tumblers to their normal position. As the door is closed the tumbler-returning plate by contact of the plate extension 26 with the frame of the door is returned to its normal position and out of contact with the operating-pins.
