ION GOLDFAIN, OF PHILADELPHIA, PENNSYLVANIA.

PA D L O C K SPECIFICATION forming part of Letters Patent No. 460,636, dated October 6, 1891..

Application filed January 10, 1891. Serial No. 377,344. (No model.)

To all whom it may concern.

Be it known that I, ION GOLDFAIN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Locks; 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 has relation to padlocks, and among the objects in View are to provide a padlock whose interior mechanism is such as to prevent the picking of the lock or render the same exceedingly difficult, and also to provide a padlock of very simple and inexpensive construction; and with these objects in view my invention consists in the construction, relative arrangement, and combination of parts, as hereinafter fully described, illustrated in the drawings, and specifically pointed out in the claims.

Referring to the accompanying drawings, wherein like letters of reference point out similar parts on each figure, Figure l is a perspective view of a padlock embodying my invention. Fig. 2 is an elevation of the same, with the face-plate of the lock and bolt case and the hasp removed. Fig. 3 is a detail view of the bolt-case. Fig.4 is an elevation of the inside plate of the bolt-case.

In the drawings, A indicates an ordinary lock-case, to which at one side is pivoted a hasp 13, whose free end is provided with a rectangular or other opening I), said end of the hasp being adapted to enter and project through an opening a in the top plate of the lock-case, as is usual.

0 indicates the bolt-case, comprising the front and rear plates 0 and 0', respectively, united by means of a rivet 0r stud c Said bolt-case is arranged within the lock-case and adjusted to have reciprocating limited lateral movement therein in the manner and for the purpose presently described. The rear plate a of the bolt-case is provided on opposite sides with slots 0 into which are adapted to project studs or pins 0 secured to the rear plate of the lock-case. These studs serve as bearings for the bolt-case during its lateral movements, and are so arranged that they will permit of said movements of the bolt-case, and

at the same time serve as stops to limit said movements in either direction, as will be understood.

Upon a stud 0 secured to the plate 0', is pivoted one end of a tumbler (2, whose opposite end rests upon one of the studs 0 when the parts are in a locked position, and said end of the tumbler is provided with a locking nose or projection e, which, when the tumbler is in its normal depressed position, lies behind the stud a In order to maintain the tumbler in its normal depressed position, I employ a forked-leaf spring F, supported upon a stud f, one leaf of the spring bearing against the top plate a of the lock-case and the other leaf bearing upon the upper edge of the tumbler. Secured to an upwardly projecting plate or ear cl, integral with the plate 0, is a bolt D, which is of a length sufficient to project across the opening a when the bolt-case is in the position shown in dotted lines in Fig. 2. The free end of the bolt is adapted to pass through the opening or eye I) of the hasp to lock the latter, when the bolt-case is moved to the left, in the manner presently described.

The front plate 0 of the bolt-case is provided with a key-opening 0 through which is adapted to project the stud o secured to the plate c, and the end of a key H, (see Fig. 2,) the latter having a bore which will receive and fit over the stud o G is an ordinary escutcheon.

The manner of locking and unlocking the padlock may be briefly described, as'follows: In Fig. 2 the parts are shown in the unlocked position. New to lock the hasp the latter is swung downwardly until its free end, with the eye I), enters the opening a. The key is then placed in position,its bore overlying the stud c, which within it is free to turn. It is then pressed toward the left'precisely as an ordi nary door-bolt is moved, to lead its free end within a ring-staple, thereby carrying the en tire bolt-case in that direction until the projection c rides off the stud c' and falls behind the same, the bolt D in the meantime passing through the eye I). The hasp is now locked, and the same cannot be. unlocked until the bolt-case is moved to the right to free the bolt D from the eye Z); but said movement to the right cannot be effected until the key has first been turned to lift the spring-pressed tumbler.

ICO

This is eifected by turning the key l-I until its bit engages the underside of the tumbler, as seen in Fig. 2, and raises the latter and with it the projection 6 above the stud 0 Then by pressing the key to the right the boltcase is caused to move in that direction, whereby the bolt D is withdrawn from the eye 5 of the hasp, and the latter can then be swung upwardly.

It will be seen that a simple turning of the key, as in ordinary padlocks, is not sufficient to effect the unlocking of the hasp, but that a sidewise movement of the bolt-case must be had, and thus the precise mode of unlocking the padlock would be puzzling to a person attempting to pick the lock, rendering the operation diificult, if not impossible, to accomplish.

Having now fully described my invention and the manner of its operation, what I claim, and desire to secure by Letters Patent of the United States of America, is

1. In a padlock, the combination, with a lock-case and its hasp, of an inner hollow boltcase arranged within the outer case and adapted for reciprocating lateral movement therein by pressure of a key overlying stud 0 said key when turned operating a spring-c0ntrol1ed tumbler pivoted to the bolt-case, said lockcase having studs that engage guiding-slots on the hollow bolt-case, and a bolt integral with and carried by said hollow bolt-case, the bolt adapted to engage and release the free end of the hasp when the bolt-oase is moved in one or the other direction,substantially as described.

2. In a padlock, the combination, with the lock-case and hasp, of a bolt-case arranged within the lock-case and adapted for lateral movement therein and provided with guideslots, studs arranged within the lock-case and projecting within said guide-slots, a bolt carried by said bolt-case, and a spring-actuated tumbler pivoted to the latter and provided with a projection adapted to engage behind one of the studs, as and for the purpose specified.

In testimony that I claim the invention above set forth I aflix my signature in presence of two witnesses.

ION GOLDEAIN.
