PERMUTATlON-PADLOCK.

SPECIFICATION forming' part of Letters Patent No. 486,665, dated November 22, 1892.

' Application filed October 29, 1891. Serial No. I110,174. (No model.)

To all whom it may conoern: p

Be' it known that I, JosIAH J. DEAL,a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Combination-Padlocks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

. My invention relates to an improvement in combination-padlocks; and it consists of certain features of construction and combination of parts, as will be hereinafter described,

and pointed out in the claims.

Figure 1 of the accompanying drawings is a perspective, comprising the lock-case, the shackle, re'movable lid or cover, and the lock- Springs; Fig. 2, a plan showing the location of the several parts in the case; Fig. 3, a plan of the front side of the lock, showing the turnpin by which the combination is operated; and Figs. 4, 5, 6, 7, 8, 9, 10, and 11 are perspectives of the tumblers and spacing-washers hereinafter explained.

Similar letters of reference indicate corresponding parts in all of the figures of the drawings.

Krepresents the lock-case, which, as shown in Fig. 1, is preferably made of cast metal, and is substantially of the form shown, having' a face portion a, and sides b. At the shackle end of the case is provided a block or lug portion 0, in which is provided a circular groove or raceway cl to receive the shackle L and in which the shackle is turned to release whatever may have been held therein or thereby. There is also provided in the block c a circular socket e, in which is seoured one end of the rackspring M, the free end of said spring having a V-shaped bendfadapted to the space g between the rack-teeth h. There is also provided a stud, having therein a circular socket j to receive one end of the tumbler-brake spring N. The free end of said spring is bifurcated, the prongs k to rest on the periphery of the tumblers B and H, as shown in Fig. 2. There is also provided, as shown in Fig. 1, an inWardly-projected hub Z, in which is journaled the turnpin or turn-button m. About the outer edge of the side bis provided a groove??I to receive the edges n' of the back of the case. To secure said back in position,

a groove o is formed in the block c (cutting into the groove d) to correspond with a lug p on the inside of the lid. To place the lid O in the case K, the shackle is turned in the raceway to bring the opening over the groove o and the edges of the lid passed into the side groove. The lug p of the lid, entering the opening in the shackle, will pass in with and through to the opening into the groove o, the lug resting in the groove inside of shackle, in which position it is looked by the shackle, closing over ,the end of the groove and the lug, and cannot be renioved until the lock is opened and the shackle turned to let the lug pass out.

The spring-actuated looking-bar P has a perforated body portion r, a forwardly-projected bar orrarm 8, having at the upper side end portion a lug t to enter into the opening q in the shackle, a downwardly-projected lug U to rest on the peripheries of the tumblers, and a tail-piece V, projected at one side of the body at right angles with the arm S, said tail-piece to rest on one end of a coil-spring w, the other end of the spring resting on the side of the case. The energy of the spring is exerted to hold the lug t in the opening q in the shackle. The lug u, resting on the tumblers, the shackle cannot be turned. The case K is also provided with an inwardly-projected hub :12, in which is journaled a turn key or button y, having on its inside end portion a T portion z, the ends of which are adapted to engage teeth h of the Wheel D, as will be hereinafter explained. I prefer this form of device for rotating the rack -wheel over a driver having a continuous engagement with the teeth of the rack-wheel, as the movement can be noted distinctly for counting.

The tumblers A B E G H and the toothed wheel D are preferably made from sheet metal and are formed as shown, having a central perforation ,22, encircled by a series of small perforations 23, peripheral notches ,24, and studpins z and placed in the case about the hub lin the following order: The tumbler A is first placed on the hub, the pin z projecting outwardly. Tumbler B is next passed over the hub Z and down onto tumbler A. The pin z is passed into the small perforation next or under the figure 1 on the face of the tumbler. Washer Cis next passed onto the hub, which is followed by the rack-wheel D. The

IOO

pin zs in the rack-wheel projects from each side, the projection from the lower side to engage the pin on tumbler A. Tumbler E is now passed over the hub, the pin 2:5 on the rack-Wheel to enter the small perforation za under the figure 2. TasherF is next placed on the hub, followed by tumbler G, which is provided with a cut-out keyway for feather 27 at the inner end of the turn-key m. Tumbler I'I is now passed on the hub, the pin z on the tumbler in the first perforation z3 to the left of the one under the figure 3. VVhen the tumblers are so placed in the case, the spring M resting in the notches on the turnbler or rack D and the spring N as a brake on the edges of the tumblers B, E, and H, the peripheral notches 2'4 may be brought in line under the lug U on the looking-bar P. To rotate the shackle 01' unlock, the pin m is turned in the direction of the arrow until the finger 58 reaches the dot ,29. turned to the right one notch or click of the spring m on the rack-wheel. This movement will carry the notch 54 on tumbler B under the lug U. 'Then one revolution or two clicks to the left will carry the notch .24 on tumbler H under the lug U. Now turn the pin one and a half turns 01' three clicks and the notch z* in tumbler E will be brought into line under the lug U, so that the shackle L may be turned in lts groove to allow the opening q to pass out of the case to release the lock. To lock the shackle, turn it back into position shown in Fig. 2. The spring VV will throw the lug t into the opening q. The combination may then be distributed by turning either Pin Y is then.

of the pins m or y, and the arm P will be locked in the shackle, as shown in Fig. 2.

Having thus fully described the nature and object of my invention, what I claim, and desire to secure by Letters Patent, is-- l. The combination, With a lock-case having a face portion a, side b, having at its outer edge a groove n, a stud fi, having a circular recess j therein to support the spring N, a head-block c, circular raceway (Z, groove o, eX- tending from the body of the lock to the raceway,a hub Z to support the tumblers, and pin m, of the shackle L, locking-bolt P, tumblers A B E G I-I, rack-wheel D, Springs M and N, and turn-pins 'm and y, the latter having a cross-bar z, the ends of which are adapted to engage and rotate said rack to register the notches 2'4 under the lug U to release the shackle, substantially as set forth.

2. The combination, with a lock-case having a face portion a and sides b, grooved at their outer edge to receive a sliding,r lid or back,ofa block end portion c, having therein a circular raceway d and a groove o, a lockingbolt P, a lid or back provided with an outwardly-projected lng p, adapted to slide in the groove 0, and a shackle to turn in said raceway to engage the end of the lug p to lock and hold the lid in the case, substantially as set forth.

In testimony whereof I have hereunto set my hand this 9th day of October, A. D. 1891.
