FRANK. ANDERSON, or OAKLAND, CALIFORNIA.
COMBINATION-PADLOCK.
To all whom it may coacern."
Be it known that I, FRANK ANDERSON, a
citizen of the United States, and a resident of Oakland, county of 'Alameda, and State of California, have invented a new and useful Combination-Padlock, of which the following is a specification.
My invention relates to locks andan ob ect of the invention is to provide an 1mproved combination lock of the padlock type, and one in which the parts are inseparable with the staple in place. Another object of the invention is the provision ofa lock of .the type described in which the position of the tumblers is determinable by sound as well as by visible means so that the lock may be opened in the dark.
The invention possesses other features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the speclfication. It is to be understood that'I do not limit myself to the showing made by the said drawings and description, as I- may adopt variations of the preferred form within the scope of my invention as set forth 1n the claims.
Referring to the drawings:
Figure 1 is a view of the lock chiefly in vertical section. Fig. 2 is a view partly in vertical section of the lock from a point 90 from that of Fig. 1. Fig. 3 is a plan view of one of the division rings. Fig. 4 is a vertical sectional view of the cap plate. Fig. 5 is a bottom view of one of the tumbler rings and Fig. 6 is a vertical sectional view of one of the tumbler rings.
My lock comprises a barrel 2 having an integral flange 3 at the lower'end and a cap plate 4 at the other end, threaded on to the stud 6 projecting from the barrel. The cap plate thus forms a flange at the upper end of the barrel and between the two flanges, tumbler rings or tumblers 7 8, 9 and 10 are disposed.
One of the tumblers of which there 'are preferably four, is shown in Figs. 5 and 6 and is formed with an inwardly extending flange 12, the inner edge of which forms a running fit with the barrel. The peripheral surface 13 of the tumbler is rounded as shown in Fig. 6 and knurled to provide a finger grip. Flat areas 14 are formed at interva s, an num er 15, o er d ie Specification of Letters Patent.
Patented nee. 2a, 1921.
Application filed April 19, 1920. Serial No. 374,789.
preferably from 0 to 9 inclusive, are stamped thereon, so that the tumbler may be turned into the desired positionin accordance with the combination by registering a certain numbered area with a. mark 17 formed on the cap plate. Exact registration is insured and an audible signal given by a click pin 18, slldably arranged in the barrel, and pressed outwardly against the inside surface of the tumbler byv a spring 19. The tumbler is provided with recesses 21 opposite each numbered area except that bearing 0, and the ngagement of the rounded end of theipinin the recesses audibly indicates the registration of the numbered area with the mark 17, lnsures the exact position of the tumbler, and prevents-accidental rotation thereof. The recess opposite the character 0 is omitted so that no click occurs at this point. The double length of time between clicks indicates the position ofthe tumblers to one turning them in the dark, so that they can be positioned in accordance with the combination by counting the clicks in each after the silent interval. Y
The flange 12 of each tumbler ring is formed with a semi-circular recess 22 so placed that when a selected numbered area is 1n registration with the mark 17, the recess is registered with a Semi-circular groove 23 formed lon itudinally in the surface of the barrel. l/ hen the recess 22 of each tumbler ring is placed in registration with the semi-circular groove, a cylindrical aperture is formed in line with the aperture 24 in the cap plate, into which the long leg 26 of the staple may be thrust, the short leg 27 seating in the cap plate in the aperture 28. The long leg of the staple is provided with notches 29, which are in alinement with the flanges 12 when the staple is in place, so that rotation of the tumblers engage the flanges in the notches of the staple, thus preventing its withdrawal. 4
With the staple in position, the cap plate cannot be unscrewed from the barrel, so that the lock is impregnable except to great violence. To prevent movement of the cap plate when the staple is out a screw 31 is threaded through it, the point engaging in a recess suitably formed inv the upper face of the barrel.
To avoid accidental movement of one tumbler by another, the tumblers are separated by division rings 32 prevented from rotation 99 the barrel by engagement of a lug 33 in a longitudinally disposed groove 34:, formed in the side of the barrel opposite the groove 23. Each ring is also termed with a recess 36 in register with the groove 23, so that entrance and withdrawal of the staple is not interfered with.
From the above it will be seen that the tumblers are retained on the barrel by the cap plate which is locked to the barrel by the staple when the staple is in position to 'beengaged by the tumblers.
The combination of my lock is readily changed by transportation of the tumblers.
I clann:
1. A combination padlock comprising a barrel formed with a fiangeat one end and astud at the other, a cap plate threaded on 7 said stud to form a second flange on said barrel, tumbler rings on said barrel between said fianges and formed With recesses in the surfaces of the ring apertures, spring-pressed pins slidably arranged in the barrel to yieldingly engage in the recesses morass of said tumbler rings, a staple piercing said cap to lock it against movement and engageable with said tumbler rings, and indicia on said tumbler rings and on said cap plate for positioning said tumbler rings.
2. A combination padlock comprising a barrel formed with a flange one end and a'stud at the other a cap plate threaded on said stud to form a second flange on said barrel, tumbler rings on said barrel between said flanges and formed with recesses in their apertures, spring-pressed pins slidably arranged in the barrel to yieldingly engage in the recesses of said tumbler rings, di vision rings stationary on said barrel for separating said tumbler rings, a staple piercing said cap to lock it against movement and engageable with said tumbler rings, and indicia on said tumbler rings and on said cap plate for positioning said tumbler rings.
In testimony whereof, I have hereunto set my hand.
