PERM'UTATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 330,137,dated November 10, 1885.

Application filed May 25, 1885.

To all whom it mag concern.-

Be it known that I, WALTER E. MALLEY,

of New Haven, in thecounty of New Haven.

and State of Connecticut, have invented a new and Improved Combination and Permutation Lock, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved combination and permutation lock which is simple in construction, safe and reliable, and not apt to get out of order.

The invention consists in the combination,

with a casing,a sliding bolt, and a sliding tum bler,ofratchet-wheels adapted to engage with the tumbler, and of push-pins or other devices for turning the ratchet-wheels to permit the tumbler to slide,the said ratchet-wheels beingv secured to the same and to the ratchet-wheels "Each ratchet-wheel is providedwith a laterally-projecting pin adapted to engage with a pin or projection on the casing.

The invention also consists in parts and details and combinations of the same, as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a cross-sectional elevation of my improved lock on the line a: m, Fig. 2. Fig. 2 is a longitudinal sectional view on the line y y, Fig. 1. Fig. 3 is a plan view of the bolt. Fig. 4 is a perspective view showing the ar rangement of the push-pins. Fig. 5 is a face view of one of the ratchet-wheels. I

In the casing A a sliding bolt, B, is held, the beveled end of this bolt being projected from the end of the casing by a spring, B, in the usual manner, and the said bolt being pro vided at its forked inner end with teeth or projections 13*, on which the arms G (J of a nut, 0 on the knob-shaft O are adapted to act for the purpose of withdrawing the bolt. A

sliding tumbler, D, is provided at the ends with notches or recesses D, which engage the Serial No. 166,589. ,(ModeL) tongues or cross-pieces E, secured to or cast upon the casing, and adapted to guide thesaid tumbler. The tumbler is also provided in its upper edge with a notch or recess, D into which the end of the downwardly-projecting arm 0 of the nut (3 passes. The tumbler is drawn in the inverse direction of the arrow a a, is held, the said pins being adapted to strike corresponding pins, I, projecting from the inner surface of the casing. Adjacent to each ratchet-wheel a fiat spiral spring, J,

is coiled around the shaft, and has one end secured to the said shaft and the other end to the side ofthe ratchet-wheel, the said springs swinging the wheels in the direction of the arrow 1), Fig. 1. Against the toothed edge of each ratchet-wheel a locking-spring,

. K, rests, which is secured to the casing at or near the bottom. From the side of the casing a rectangular orother neck, L, projects, which is provided with an extension-piece, L, fitting in the said neck, the said extension-piece being provided with an escutcheon-plate, M, to fit on the outer surface of the door, in which the lock is mortised. This extension-piece has to be provided, as the thicknesses of doors vary. In some cases the escutcheon-plate M is on the outer edge of the neck L, and in some cases it is a greater or less distance from the same.

The neck L can be held in the casing in any suitable manner, but I prefer to form eyes s on the edges of the opening, and correspond ing eyes on the inner edges of the neck, the eyes of the neck and opening interlocking, and then I pass a screw, t, through the said eyes from the end of the lock-casing, thus holding the neck on the casing.

In the plate M three pins, N N 2 N, are held of each pin a pawl, O, is pivoted, which is held raised by a spring, P. The pawls are so arranged, that they can act upon the corresponding ratchet-wheels, H, H and H Spiral springs Q surround the'push-pins N N N and push them outward. Below the above-mentioned push-pins a push-pin, R, is arranged in the plate M, which is also pressed outward by a spring, Q, and has a cross-piece, It, on its inner end, the said cross-piece extending across to the spiings K, as shown in Fig. 4. To the inner end of the push-pin N an elbow, n, is secured, and projects downward, and to the elbow a crosspiece, n, is secured, which is provided at each end with a tooth, M, the said teeth a being adapted to act on the springs K of the ratchet-wheels H andH On the push-pin N adownwardlyprojecting elbow, m, is secured, and to the same a cross-piece, m, is fastened, which is provided on its free end with a tooth, m

adapted to act onthe spring K of the ratchetwheel H The cross-pieces or rods n m constitute the permutation devices, and may be left off or may be applied, as desired.

' In the bottom of the sliding tumbler D two notches, S, are formed, which correspond in position to the ratchet-wheels H and H, the end of the tumbler being adjusted to the third ratchet-Wheel, and in that edge of each notch- S facing the ratchet-Wheel.

The operation is as follows: To unlock the lock, the notches H of the three wheels H H 11 must be inline, so that the tumbler can be passed into the said notches. In order to bring the notches in this position, the wheels are revolved the distance of one, two, or more teeth by means of the push-pins N N 2 N By pushing the said pins in their pawls engage with the teeth of the ratchet-wheels and revolve the ratchet-wheels. For example, the wheel H is to be revolved the distance of one tooth, theiwheel H the distance of two teeth, and the wheel H the distance of three teeth. For this purpose the lock mnst' first be ad-. j usted, which is accomplished by placing the removable pins a in the apertures of difierent teeth. The pin a in the disk H is placed one tooth from the notch, in the disk H it is placed two teeth from the notch, and in the disk H it is placed three teeth from the notch, the said pins resting on the corresponding pins, I, as the wheels are thrown in the direction of the arrow 1) until they rest on the said pins I. If the disks or ratchet-wheels have been so adjusted that the notches are in line, the knob is turned and the bolt withdrawn, and at the same time the tumbler D is moved in the direction of the arrow a and through the notches of the ratchet-wheels. is released, the spring B pushes the bolt outward, and the spring F pulls the sliding tumblers in the inverse direction of the arrow a. The pin R is pressed inward to throw oft the springs K, or one or more of the push-pins N N N are pushed inward one or more times, so as to shift the ratchet-wheels in such a manher that the notches will not be in line, thus making it impossible to shift the tumbler.

wise the notches will not come in line.

When the knob-shaft If at any time the bolt is to be withdrawn, the push-pin R is pushed inward so as to disengage the springs K from the ratchet-wheels, thus permitting the several springs J to swing the three ratchet-wheels in the direction of the arrow 22 until they rest on their pins I. The several ratchet wheels are thus thrown into their normal position, and if they are By adjusting the pins a in holes in different teeth various combinations can be produced.

For instance, one wheel can be set to be re volved one tooth, another eight, and the other six, and so on. It is evident that a greater number of ratchet' 'wheels and corresponding push-pins can be used. The ratchet-wheels turn in the notches S of the sliding tumbler.

,When the purmutation device shownin Fig. 4. is used, the operation is somewhat different. In this case the pins must be pushed in in the proper order, the pin N first, the

pin N second, and the pin N last, as other- The pin N is pushed in first, and the teeth a on the cross-bar n push the springs-K of the wheels H and H from the said wheels, thus permitting the springs of the corresponding wheels to turn the wheels in the direction of the arrow b until their pins a rest on the pins I.

Then the pin N is pushed inward, which does not act on the spring K of the wheel H or H, but acts on the spring K of the wheel H thus again disengaging the spring from the said wheel and permitting the spring J to turn the .said wheel (if in aforward position) in the direction of the arrow 1) until the pin a of the said wheel H rests upon the corresponding pin I. Then the pin N is pushed inward,

which does not acton any of the springs K.

If by mistake the pin N is pushed in first and the wheel H brought in its proper position, and then the pin N is pushed in, the teeth n acting on the springs K, release the same from the wheels H and H thus permit-ting the springs J to swing the said wheels in the direction of the arrow 1), whereby the wheel H, which has been previously adjusted in the proper position by pressing in the pin N twice, is again thrown out of its position,

and thus prevents the tumbler from being shifted in the direction of the arrow a and the with a frame or casing, a sliding bolt,'and a sliding tumbler, of a series of ratchet-wheels adapted to engage with the tumbler, a shaft on which said wheels are mounted, springs for turning the several ratchet-wheels, locking-springs for locking the ratchet-wheels in place, push-pins for turning the ratchetwheels, and a push-pin for disengaging the lockingsprings from the ratchet-wheels, substantially as herein shown and described.
