SPECIFICATION forming part of Letters Patent No. 625,989, datedMay 30,1899. I

Application filed September 16, 1898. Serial No. 691,102. (No model.)

To al whom, it may concern:

Be it known that I, JOHN AUTEs LATROBE SNYDER, a resident of Somis, in the county of Ventura and State of California, have invented certain new and useful Improvements in Combination-Padlocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in combination-locks, and particularly to padlocks designed for use as bicycle-locks, such as shown and described by Letters` Patent granted to me on the th day of May, 1898, No. 603,7l1,the object of my presentinvention being to simplify, improve, and strengthen the construction disclosed by my former patent, whereby to simplify and improve the same and render it more efficient, secure, and convenient to manipulate.

With these objects in' view my invention consists in certain novel features of construction and combinations and arrangements of z5 parts,as will be more fully hereinafter devs'ciibed, and pointed out in the claims.

In thc accompanying drawings, Figure l is a view in perspective of my improved lock. Fig. 2 is a longitudinalsectionai View. Figs. 3 and 4 are vertical transverse sectional views. Figs. 5 and 6 are horizontal trans- Fig. 7 is aview showing tumbler 16, a locking-plate 18, Aand a washer 22. Fig. lS is a detail viewshowing one of the shackle-legs and the relation of the securing-pin 9 thereto. Fig. 9 is a longitudinal sectional View of the lock-casing with the tumblers removed and the shackleshown in elevation.

' l represents the body portion or casing of my improved lock and is preferably composed of asin gie piece of metal provided with a longitudinal slot or opening 2 a little to one side of the center thereof, intersected by a plurality of tumblers or pin-guides 3, five ofthese guides or holes, arranged alternately, being shown in the drawings.

The shackle 4 is provided with a long arm y 5 and a shorter arm, adapted to be fitted in formed parallel with parallel shackle-arm yguides or sockets 7 8,

thelongitudinal slot or opening 2. A key or securing-pin 9 is disposed in a key guide or socket 10 in close proximity to the long shackle-arm socket 7 end. The key or pin 9 is provided at its upper end with a lug or projection 11, adapted to bear against a flat portion 12 of the long shackle-arm 5, said long shackle-arm having a shoulder 13 atthe upper end of the fiat portion and a shoulder 14 at the lower portion thereof and provided with a groove or recess l5 near its lower end, extending partially around it to permitthe partial turning of the shackle when the lock is unlocked and the pin or key 9 is in place. A

pin seats or guides 3 are the tumblers or lockthan the width of the lock-casing and fitted between the walls ofthe slot or opening 2, With coiled springs 17 and locking-plates 18. Each plate 18 is provided with an elongated slot 20, enlarged and rounded at one end, as at 21, so as to be of sufficient size to permit a tumbler or pin 16 to turn therein. Each tumbler or pin is provided with parallel dat faces 23, which are engaged by the contracted portion of the slot or opening 2O ofa plate 18 when .the tumbler or locking-pin is in the p0- sition desired. Each tumbler or locking-pin 16 is provided with two of these plates 18 (at the respective walls of the opening or slot 2) and have the coiled spring 17 between them,

16 to be pushed in either direction and returned to their normal position. Suitable washers 22 may be placed at each end of the spring to prevent its displacement when the plates are moved. The plates 18 when their slots 2O are fitted in portions 23 of the tumblers or pins 16 will move therewith andprevent any unauthorized withdrawal of the tumblers or pins.

The shackle-legs 5 6 and the key or pin 9 are recessed or` cut away in the planes of the tumblers or locking-pins to form tumblersimilarly cut away or recessed at intervals on one side in alinement with the shackle-legs and key or pin 9 and are cut away or recessed on their vopposite sides slightlyout of the and communicating therewith near its upper Fitted in the transverse tumbler or locking- 1 thus permitting the tu mblers or locking-pinsy ing-pins 16, each being of a length greater seats 25,- and the tumblers or locking-pins are IOO ' eating numeral or sign, and when it is desired to form a certain combination it is simply necessar to give the tumbler or locking-pin a half-turn, the result of which will be to present the side of the tumbler to the shackle- Varms and pin 9, where the recesses are out of alinement therewith, and hence the spring will normally hold a portion of the tumbler idr pin in the recessed portion,of the shacklellegs and pin 9 and prevent the withdrawal of the shackle from the lock. Any number of these tumblers or locking-pins may be turned and form part of the combination.

Whenuit is desired to unlock the lock, it is simply necessary to push the tumblers forming part of the combination, when the recesses therein will be brought into alinement with the shackle-legs and pin 9. A spring 26, provided at the lower end of'the pin 9, will then force same upward, and the projection 11 on the upper end of the pin 9 will bear against the shoulder 13 of the shackle-arm 5 and f orce same upward. The pin 9 will then serve to hold the tumblers forming part of the combination in such position that the recesses therein will be in alinement with the shackle-arms and permit the easy withdrawal of the shackle until the shoulder-'14;A of the long arm 5 of the shackle abats against the lug or projection 11 of the pin 9, which will prevent the entire withdrawal of the shackle, but permit it to turn (due to the recess 15in the arm 5) a sufi-d cient distance tq release the articles locked.

` A metallic band-22e is adapted toLfit snugly around the frame',inc'losing the opening 2 and preventing the'withdrawal of the pin 9.

,When it is desired to lock the device, itis simply necessary to force the shackle down- '.wardnntil the shoulderl en gages the lug or projection 11 on the pinl9,' which will/force said pin downward and release ,the tumblers or locking-pins held thereby and permit same to spring into 'the recesses in the shackle-arms and pin 9, and hence lock the shacklein place.

When it is desired to place a new tumbler or locking-pin in the combination or to take out ofthe combination one already in, it is simply necessary to remove the band 27 and move the plates 18 of that particular tumbler or pin until the enlarged portion 21 is in alinement with th@ tumbler and then give the tumblerI a halffrevolution and move the plates 18 back, thus permitting the contracted portion oi--the slot 20 to engage the dat parallel faces .23m-the tumbler, and hence secure same in Planegg., v ,v

*Ags many tumblers or pins as desired may be placed in the, combination, and it will be 'readily seen that with my improved lock the owner of the lock can readily change the combination of his lock as often as he likes with practically littletrouble.

Various slight changes might be made in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it .understood that I do not wish to limitmyself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly'fall within the spirit and scope of my invention.

I claim as new, and desire to secure by Letters Patent, is
