KEYLESS PADLOCK.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed January 16, 1905. Serial No. 241,312.

To all whom it may concern:

Ee it known that I, GEORGE W. KONE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful improvements in Keyless Padlocks, of which the following is a specification.

My invention relates to improvements in ocks.

It relates particularly to permutation padlocks in which the use of keys is dispensed with.

The object of my invention is to provide a keyless padlock of the character described which is capable of being set to many combinations, which is reliable in operation, not easily4 disordered, is cheap to manufacture, and which possesses great durability.

My invention provides a construction in which the operator may quickly change the combinatiim.

1t provides further a construction of lock by which the operator may easily adjust the tumblers to the proper position for unlocking by the aid of the sense of feeling alone, thus enajbling one to unlock the mechanism in the dart.

Other novel features are hereinafter fully i l? ig. d is an end elevation of the padlock with the cap and shackle removed. Fig. 5 is a side elevation of the padlock. Fig. 6 is a rear end view of a tumbler. Fig. 7 is an end view of the inner member of a tumbler.

Similar characters of vreference denote similar parts.

1 denotes the crown having a central tubular part 2 closed at its re ar end and having a lateral opening 3 to receive the shackle 4, the inner or free end of which is notched to receive a slide bolt 5 reciprocatively mounted in the tubular portion 2 of the crown l. The slide bolt 5 preferably comprises a cup shaped body the bottom of which is provided with a recess 6 adapted to receive therein the notched end of the shackle. A coiled spring 7 bears at one end against the slide bolt 5 and at the other end upon the inf ner side of the closed end of the crown 1.

The tension of the spring 7 is such as to normally force the slide bolt 5 forward into engagement with the shackle.

Secured at one end forward of the opening 3 to the crown 1 is a connecting member 8 comprising preferably a tubular post longitudinally slotted at one side and having its other end externally screw threaded. Rotatively mounted on the screw threaded end ofthe post 8 is a cap 9 to which the shackle 4L is pivoted. Reciprocatively mounted in the post or tube 8 and extending through the central portion of the cap 9 is a member comprising preferably a slidable bar having a series of lateral projections 11 extending laterally through the slot 10 of the post 8, the slidable bar being denoted by 12. The rear end of the bar 12 is provided with a projection 13 which enters a hole 14 in the bolt 5 and prevents rotation of the bolt 5 in the crown. In the outer end of the post disposed diametrically opposite the slot 10 is a slot 15 in which is mounted a projection 16 on the bar 12 which with the projections 11 prevent rotation of the bar in the post.

The outer of the projections 11 is adapted when the bar 12 is not moved to enter a recess or hole 17 provided in the cap 9 and revente rotation of the cap on the post 8, but when the bar 12 is moved inward the projection is withdrawn from the recess 17 and the cap may be unscrewed and detached from the ost to enable the operator to remove andD change the combination of the tumblers.

The tumblers are rotatively mounted between the cap 9 and crown 1 and encircle the post 8 and bar 12. Each tumbler comprises an outer annular member 18 preferably of cup like form and provided on its inner periphery with a plurality of circularly arranged recesses 19 adapted to receive a rearwardly extending projection 2O provided on the rear side of the inner member 21, which is also preferably of annular cup like form, the transverse or bottom portion of which is disposed so as to engage with and prevent movement of the bar12 when the inner member is disposed in any other than a certain position. The bottom of each inner member of each tumbler is provided with a slot 22 through which the outer adjacent proj ection 11 may pass when all the tumblers are ico disposed so that the slots 22 are in alinement with the ,projections I 11. When so positioned the bar 12 may be moved, thus forcing back the slide bolt 5 against the pressure of the spring 7 and releasing the shackle 4 from the bolt 5 and permitting the withdrawal of the shackle from the opening 3. Vhen the bar 12 is moved inward the outer projection 11 is withdrawn from the hole or recess 17 and the cap can be removed as above described. The tumblers may then be removed from the post 8 and the inner member 21 of each turned to any desired position.

The outer member 18 of each tumbler is provided with a series of transverse grooves 23 disposed parallel with the axis of the member and arranged at equal intervals around its outer periphery thus dividing the periphery into a series of raised portions corresponding in number to the number of recesses 19. One of said raised portions may be provided with a projection 24 which furnishes a starting point by which the operator may by feeling properly rotate the tumbler to the position required for unlocking the padlock. For convenience another projection 25 differing in coniiguration from the projection 24 may be provided on the raised portion disposed diametrically opposite the one having thereon the projection 24. The projection 24 may be pointed and the proj ection 25 flattened for effecting a ready recog nition between them. The other raised portions on the outer member 18 may be numbered or provided with other suitable distinguishing devices. The periphery of the crown 1 may be provided with one or more grooves 26 to serve as guides for properly locating the different tumblers. VV hen disposed in the locked position as shown in Fig. 1, the projections 11 lie respectively forward of the bottom of the inner members 21, thus permitting free rotation of the tumblers to and fro.

The outer members are rotatively iitted respectively in each other and in the crown, a shoulder being provided on the rear ond of each outer member for this purpose. The cap 9 is mounted in the outer or forward one of the outer members and prevents forward movement of the inner member of the outer tumbler, the outer members of the rear tumblers preventing forward movement of the other inner members 21.

To unlock the padlock, the combination being known to the operator, he turns the tumblers to positions in which the slotted positions of the inner members 21 will be in alinement with the projections of the bar 12. The bar 12 is then moved rearwardly, thus moving the bolt 5 and releasing therefrom the shackle 4. To lock the device, it is but necessary to insert the free end of the shackle into the opening 3. The shackle will force the bolt 5 rearwardly until the projection at the rear edge of the notched end of the shackle is opposite the hole or recess 6, at which time the spring 7 will force the bolt 5 forward and causing the bolt to enter the notch in the shackle.
