PADLOCK.

SPECIFICATION forming part of letters Patent No. 410,027, dated August 27, 1889.

\ Application tiled March 16 1889. Serial No. 303,576. (No model.)

T0 all whom it may Concern.-

`Be it known that I, MICHAEL RUECKERT, a citizen of the United States, and a resident of St. Marys, in the county of St. Genevieve and State of Missouri, have invented certain new and useful Improvements in Padlocks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a side view of my improved padlock closed. Fig. 2 is a similar view taken at right angles to the View shown in Fig. l. Fig. 3 is a longitudinal vertical sectional view showing the lock closed. Fig. 4 is a perspective view of 'the lock as it appears when partly open. Figs. 5 and 6 are perspective views of the upper and lower halves, respectively. Fig. 7 is a perspective detail View of the interior of the movable locking thimble 0r sleeve. Fig. 8 is a similar view of the threaded key-pin. Fig. 9 is a similar view of the key used in conjunction with that form of pin, and Fig. 10 represents a` cross-section on line :c in Fig. 1.

Like letters of reference denote corresponding parts in all the figures.

This invention relates to padlocks of the class known as link-padlocks or lockinglinks, and has for its object to produce a lock which while inexpensive and simple in its construction shall yet be very strong and durable and easyl of manipulation.

To this end my improvement consists in the detailed construction and combination of parts of a lock of that type, as will be hereinafter more fully described and claimed.

Reference being had to the accompanying two sheets of drawings, the letters A and B designate the two halves of the link proper, the part A being provided on one side with a fixed sleeve C, on the inner side of which are two projecting studs .e c, opposite to each other, while the lower end of the other side is provided with a so-called bayonet-catch a. The other half part B has one of its ends grooved with two grooves b and b,'and is notched, as shown at d and d', Fig. 6, for the insertion of the studs or projections c c, when the grooved arm of part B is inserted into and interlocked with the iixed sleeve C of the part A. Thus it will be seen that the two parts A and B are swiveled together detach- `ably by means ot sleeve C. The other arm cess a in part B is bored a screw-threaded aperture D, having an enlargement D at its outer end for the insertion of the threaded keypin E, (see Figs. 8 and 10,) which has a head e, of such a shape that it will t into the key used for opening or closing the lock, one form of which is shown in Fig. 9, and is provided with an offset f on one side, which, by striking against a projection within the en largement or key-hole D', will limit the play of the threaded key-pin to either side, thereby preventing it from being screwed out too far and becoming lost. Upon the same part B is placed th'e sliding locking-thimble F, which has an aperture G, adapted to register with the key-hole D when the sleeve is turned into its proper position for opening or closing the lock. On the inside of this sleeve, Fig. 7, is a projecting stud g, adapted to t into the`bayonet-catch a and its registering-extension a', and also a groove or recess 7L, adapted to receive the inner end of the threaded keypin E when this is screwed home by turning it with the key.

From the foregoing description, taken in connection with the drawings, the operation of this device will be readily understood. The lock being open, in the position shown in Fig. 4, if it is desired to lock it the swiveled part B is turned until its free end, carrying the locking-thimble F, registers with the corresponding arm ot' part A, in which position the lower notch of the bayonet-catch a in part A will register with the recess a in part B, into which the inside stud g of thimble F projects. The parts being in this position, the -thimble is pushed up upon part A, so as to cover the bayonet-catch, and then turned to one side, causing the projection g to enter and engage the upper notch of the bayonetcatch, and thereby locking the two halves A and B together. Turning the thilnble into this position Will bring its aperture G opposite to the key-hole D', and by noW inserting the key and turning the key-pin E in its threaded hole its inner end Will project into the groove or recess-h in thinible F, so that this cannot be slid down upon its appropriate arm of partB to unlock the lock. After this the sleeve is again turned, so as to cover the key-hole, when the operation of locking is completed. To unlock, this procedure is simply reversed.

Hav'ing thus described my invention, I claim and desire to secure by Letters Patent of the United States- In a padlock, the combination of the inein- MICHAEL RUECKERT.
