J. SINGER ET AL PADLOCK Filed April 14, 1922 Patented Sept. ,2, 1924,
UNITED STATES JAMES SINGER AND PAUL REKETTYE, OF EAST AKRON, OHIO.
Application filed. April 14, 1922.
T all whom it may concern:
Be it known that we, JAMEs SINGER and PAUL REKETTYE, the first a citizen of the United States, and the second a citizen of Hungary, residents of East Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Padlocks, of which the following is a specification.
This invention relates to a combination padlock.
Among the objects of the invention is to provide a lock of the above character which is exceedingly simple in construction; which consists of few parts; which will resist great force against opening when locked; and which is easy to manipulate for opening or closing.
Other objects and objects relating to details of construction, combination and arrangement of parts will hereinafter appear in the detailed description to follow.
The invention is illustrated by way of example in the accompanying drawings, in which Figure 1 is a perspective view of a lock constructed in accordance with the present invention.
Figure 2 is a group view of the different parts which constitue the lock.
Referring to the drawings more particularly, H indicates generally a shackle, L a locking-pin, K a keeper-pin and A, B and C the combination lock-sleeves.
The shackle H is U-shaped, however, this particular form of shackle is not entirely necessary as is obvious. The locking-pin L consists in a cylindrical body portion which terminates atv its one end in a head 11, said head having a pair of lugs 12 extending therefrom which are sufficiently spaced to receive the eye 13 formed upon the other end of the shackle H; and said lugs being pivotally connected to the shackle by the means of a rivet 14. The rivet 14 is used in order to make it extremely difficult to disjoint the shackle from the locking-pin. The locking-pin is further provided with a longitudinally extending groove 15 which should be substantially of the depth shown in Figure 2; and arranged longitudinally of the locking-pin, diametrically opposite of the grooves 15, are the studs 16. The studs 16 are equally spaced with respect to each other and substantially square in cross section.
Serial No. 552,667.
The keeper-pin K consists in a body portion 17 which is substantially square in cross section and which terminates at its one end in a circular head 18, said head having its lower portion 19 extending from the corresponding side of the locking-pin, and this portion of the head being provided with a recess 20 which is adapted to receive the projection or lug 21 formed upon the other end of the shackle H. The keeper-pin K is further provided with protrusions or teeth 22 which are rectangular in shape. The keeper-pin K is adapted to slide freely within the groove 15 of the locking-pin L.
The construction of each of the sleeves A, B and C is entirely the same. The sleeve A in Figure 2 has a portion broken away in order that the interior construction thereof may be disclosed, and as is seen, there is formed upon the inner periphery of the sleeve the two ribs 23 and 24 to form the groove 25. Each rib has two segments removed for the purpose of providing two diametrically opposed passages 26, the passages of one rib being in staggered relation to the passages of the other.
Each sleeve A, B and C is provided at each end with graduation marks 27 which in each instance extends entirely about the sleeve and provide similar reference characters for arranging the sleeves. In the present instance numerals are used, and the graduation marks and numerals are so arranged that similar numerals of adjacent sleeves may be brought into registering relation with one another by rotation of the sleeves.
In assembling the present lock, the locking-pin L is of course properly pivoted to the shackle and then the sleeves A, B and C are positioned upon the locking-pin L after which the keeper pin K is slid within the groove 15. In positioning the sleeves A, B and C the same are rotated so that the passages 26 thereof may be brought to register with the different studs 16 of the locking-pin L and permit said studs to pass therethrough so that the pins may be moved longitudinally of the locking pin. 'When positioning these sleeves notice should be taken which of the reference characters of adjacent sleeves register when bringing the passages of ribs into register with studs 16 and teeth 22; and also the reference numerals should be noted on adjacent sleeves when bringing the passages 26 of the ribs 241 into registration witlrstu'ds 16 and teeth The different reference characters noted would represent the secret for within the sleeves A, Band C and from its one end to Within the groove of the locking-pin L.
The sleeves A, andyG are provided with graduations adjacent each of their edges in order that these sleeves may be reversed and thus changing the combination for locking or unlocking the keeper-pin K in'an obvious manner. o
While we have shown and described the preferred form of our invention, we Wish it I to be understood that we are aware of the fact that the construction, combination and arrangement of parts may be changed by those skilled in the art without departing from the spirit of the invention as indicated by the appended claims' WVe claim 1. A look of the character described comprising a shackle, a lockingpin pivoted at the one end of said shackle, a keeper-pin adapted to slide in a groove longitudinally of the locking-pin, a plurality of elongated sleeves encircling the locking pin and keeper-pin, said locking pin and keeper-pin having projections or lugs arranged longitudinally thereof and occurring upon opposite sides "thereof, said projections fitting into annular grooves upon the inner peripheries of the sleeves, said grooves having communicating channels adapted to permit the passage of the projections or' lugs when brought into alignment, and thereby to. permit the locking-pin to be moved with respect to the keeper-pin, and co-engaging means between the keeper-pin and the free end of shackle whereby the shackle may be locked to said keeper-pin when the keeper pin is moved inwardly a certain degree.
2. A lock of the character described comprising a shackle, a locking-pinpivoted at its one end to the one end of said shackle, a
keeper-pin adapted to slide'in agroove longitudinally of the locking pin, a plurality of elongated sleeves encircling the lockingpin and keeper-pin, said locking pin and keeper-pin having projections or lugs arranged longitudinally thereof andoccurring upon opposite sides thereof, said projections fitting into annular grooves upon the inner peripheries of the sleeves, said grooves hav ing communicating channels adapted "to peradjacent the ends of'each sleeve and upon the exterior thereof whereby] a known combinatlon of characters may be utlhzed for bringing the channels upon the interior of the sleeves into registration and also to enable new combinations to be had with. the I reversal ofthe sleeves.
- 8. A-lock of the character described, com-- prising a shackle, a locking-pin pivoted'at its one end to the one end of said shackle,a keeper-pin adapted to slide in a groove longitudinally of the locking-pin, a head formed upon the outer end of the keeperpin, keeper-pm,
means encircling the locking-pin and whereby the same may be locked together when said keeper-pin is moved in-' wardly a certain degree, said keeper-pin having a notch upon the innerside of its head, and a laterally extending projection upon the free end of t he'shackle adapted to engage said shackle in its closed position I JAMES SINGER;
