Description
ISAAC W. LAMB, OF
SALEM, MICHIGAN.
Letters Patent No. 86,420, dated February 2, 1869.
The Schedule referred to in these Letters Patent and making, part 0f he 53m5- .To all 'whom it may concern:
Be it known that I, ISAAC W. LAMB, of Salem, in the county of Washtenaw, and State of Michigan, have invented a new and useful Improvement in Padlocks; and I hereby declare that the following is such a full, clear, and exact description thereof as'will enable others skilled in the art to make and use the same, reference being had t0 the accompanying drawings, which form a part of this specification, in which Figure 1 is a rear elevation of my padlock, partly in section, 'showing the relative position of the several parts when unlocked.
Figure 2 is also a rear elevation, and shows the end, b', of the bolt B within the cylinder D, the nut N not being represented. l
. Figure 3 is a side elevation of the bolt B.
Figure @is a cross-section of the lock, drawn on the line x of fig. 1, showing the position of the nut and the wheels within the cylinder D.
Figure 5 is a plan of the outside of the nut N.
Figure 6 is the same as iig. 5, inverted.
Figure 7 is across-section of the nut N.
Figure lshows the position of the outer notches n of the wheels when the inner notches n' are together.
Figure 9 is a front elevation of the lock.
Similar letters of reference indicate -corresponding parts in the several drawings.
The design of my invent-ion is to provide a convenient arrangement or plan for getting to the Wheels or tumblers in a padlock, by means of which I am able to make a changeable or permutation padlock with the same facility that I can produce a permutation doorlock.
In the present case, I illustrate my padlock, constructed with wheels or circular tumblers, and the por tion of the lock that it is needful to get open in ordpr to change the combination, is lall contained within a cylinder, D, one inch in diameter,and about one-half' of an inch deep.
I close vthe cylinder D with a nut, N, that screws into it, as shown in tig. 4.
I employ a swinging bolt, B, because it is simplest, but other styles may be used with the same success.
The bolt B is really a double bolt, the upper end this specification acting as the ordinary bolt, to fasten the catch O, while the lower end moves out and in, unlocking or locking the nut N in its place.
When the upper end of the bolt B locks the catch G, the lower end, b', of the saine bolt enters the cylinder-D, .passing within a notch or recess, Z, cnt in the nut N for the purpose.
Fig.r2 represents b Within the cylinder, and figs. 6 and 7 show the notch Z in the nut into which b enters when the nut is screwed into the cylinder.
I produce the permutations in the lock herein represented, by placing the wheelsin thc lock in different order, substantially as explained in Letters Patent, N o. 7 2,408, granted to me, the 17th day of December, 1867.
I do not wish to confine myself to the precise style or form herein described, nor yet to the particular method of securing the nut or pico-eN in its place, but I design to construct some locks with circular tum blers, as in the present case, and I also design to construct other locks with the common varieties of tumblers.
It is not essential that the piece N should be a nut,
but for some styles of locks it will be perhaps Vmore convenient to employ a sliding plate instead of the nut. v
It may also be found desirable in some cases to employ a sliding bolt, B, instead of a swinging bolt, as herein described.
As I'sendat same time with this, an application for patent on a key for working my Vstyle of' wheel-tumblers, I think it not necessary to describe the key in Having thus described the peculiar features of my lock,
'What I claim as new, and desire to secure by Letters Patent, ,is-
The double bolt B, or its equivalent, so constructed and operated that the catch C and part N are both locked by the same action, substantially as herein described.
p ISAAC W. LAMB.
