SPECIFICATION forming part of Letters Patent N o."718,146, dated January 13, 1903.

Application led December 21, 1901. Serial No. 86.835. (No model.)

bination-padlock comprising very few parts in its make up, thereby minimizing the liability of getting out of order.

vide a combination-padlock of such construction that all of the parts will he connected with the lock-case at all times, thereby avoiding the liability of some of the parts becoming misplaced.

The invention consists in certain features of construction and combination hereinafter fully described, and pointed out in the claim.,

In the drawings forming part of'this specification, Figure l is a perspective view illustrating a combination-padlock constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section, the shackle and 3o bolt being shown in elevation. Fig.` 3 is a transverse section taken onntheline 3 3 of Fig. 2. Fig. 4 is a horizontal section taken on the line 4 4 of Fig. 2. Fig. 5 is a vertical longitudinal sectional View, the shackle and bolt being shown in elevation and also in their unlocked positions. Fig. Gis a detail transverse section taken on the line 6 6 ot' Fig. 5. Fig. 7 is a detail perspective view of one of the tumbler-disks, and Fig. 8 is a detail perspective view of a locking-bolt.

In the practical embodiment of my invention I employ a case A, which ispreferably made in the form of a block of met-al having a circular bore A adjacent to one end Apass-j ing entirely through the said block or case, and..

i a socket A2,.prodnced in the upper side of the block or case adjacent to the opposite end.

The case is also formed with a central openl ing As for the purpose of receiving the tumbler-disks, hereinafter described, and the case is also constructed with a transverse or hori- Another object of the invention is to pro-V zontal bore D4, Which passes through one side `of the case and communicates with the central opening and also With the vertical bore A.

The shackle B comprises the longer member B' and the shorter member B2, the member B' being arranged in the bol'e A', While the end of the member B is adapted to rest in the socket A2 when the shackle is locked. The memberB' is arranged to slide vertically 6o Within the bore A', so as to clear the member B2 from the socket A2, and after the said member has been lifted out of the socket the shackle is rotated to fully expose the free end of the shackle. A stock-pin B3 is xed in the 65 lower end of the-member B' to prevent the said shackle being Withdrawn from the case, and the bore is slightly enlarged at its lower end, as shown at A5, to permit the movements of the said pin. The lower end of the bore 7o is closed by means of aplug A6, secured in any suitable manner. A locking-bolt O is arranged to slide Vin the transverse or horifzontal bore A4, and arranged upon the bolt Within the case are the tumbler-disks D, said tumbler-disks beingpreferably circular in form and having marks and numerals D pr0- duced upon their peripheriesfor the purpose of guiding the operator in the manipulation of the lock. The bolt O is provided with a 8o series of bits C', and the tumbler-disks are each provided with a radial ward-notch D2, which permits the free passage of the bit therethrough, and consequent-ly permits'the longitudinal movement of the bolt O Within the case and through the tumblers` when the said Ward-notches are brought into alinement with eachother and with the bits of the bolt, as most clearly shown in Fig. 6.. O ne face of each disk is cut away or recessed, as shown 9o atDS, to receive the bit, thereby enabling the said disks beingarranged in close Contact with each other. Theimembekr B of the shackle has a recess or notch B4 produced therein, said recess or notchbeing adapted to receive the end O2 of thebolt,1and inasmuch as this end is shaped in the form of a dou-blebevel the notch B4 is usually constructed in the form of a V, the purpose of such constructions being made apparenthereinafter. A reroo taining-screw CB passes through the bottom of the socket A2 down into the bore A4 after the bolt has been putin place, the purpose of said screw being to prevent the Withdrawal of the bolt C.

In operation the tumbler-disks are moved around until all of the ward notches are brought into alinement with each other and with the bits upon the bolt. The shackle after being passed through the hasp or staple to be fastened is forced into the case so that the end B2 will fit into the socket A2. The notch B4 is thereby brought directly opposite the end of the transverse bore A4, and the bolt is projected inwardly by pressing upon its outer end, thereby forcing the end C2 into the notch or recess B4. The tumbler-disks are then turned in either direction, so as to throw the ward-notch out`0f register, and the locking operation is complete. When it is desired to open the lock, the disks are brought around to the proper combination, thereby driving the ward-notches into alinement with the bits upon the bolt, and by pulling upon the shackle the member B slides within the bore A', and the inclined side of the recess Bhworking upon the beveled end of the bolt C, forces said bolt outwardly, as most clearly shown in Fig. 5, thereby permitting the shackle to move upwardly, entirely lifting the end B2 out of the socket A2, and as soon as the said end is clear of its socket the shackle can be rotated upon the member B', thereby completely opening the lock.

It will thus be seen that I provide an -eX- ceedingly simple construction of combinationlock and one which owing to its simplicity is not liable to get out of order.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a lock of the kind described, the combination with a casing comprising a solid piece having vertical bores therein, one of Whichl is shallow and the other extending entirely through the casing, being enlarged near its lower end and closed by a plug, a longitudinal bore communicating with said second bore, and a recess or cut-out portion in the middle of said casing, said recess being in communication with said longitudinal bore; of a shackle having one long leg and a shorterone, the longer leg being located in the deeper bore and having a notch or V-shaped depression in its inner side and a pin or lug near its end .abutting against the shoulder formed at the juncture of the bore and the broadened or large bore at its end, thereby allowing said leg a limited vertical movement in addition to its rotary movement and the shorter leg entering and leaving said shallow bore, as said longer leg is either in its lower or upper vertical position, a locking-bolt contained in said longitudinal bore, having a limited sliding longitudinal movement therein, a pin passing through the bottom of said shallow bore into said longitudinal bore and limiting the movement of said bolt, a double bevel in the inner end of said bolt engaging the notch in said shackle-leg when the same is in its lowest position, and bits or lugs on said bolt, and tumbler-disks mounted in said central recess, upon said bolt and having radial ward-notches therein,allowing said bits to pass through and the bolt to disengage said shackle when the notches are in alinement, said tu mblers being cut out on the side to accommodate said bits when they are notin the said notches, substantially as described.
