CORDELE DI VITIATION
Permutation Padlock.
I, CHARLES CONRAD AUGUST BAUERCAMPER, Mechanical Expert, residing at
1816, Chicago Street, in the City of Omaha, in the County of Douglas and State
of Nebraska, United States of America, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
-
This invention relates to a novel improvement in locks.
The object of this invention is to provide a lock that shall embody a series of
operating buttons in connection with a series of tumblers, so arranged that the
lock may be operated without a key.
In the accompanying drawings, Figure 1 shows a view with parts removed of
a padlock constructed according to my invention.
Figure 2 shows an elevation of the tumblers.
Figure 3 shows a side view of the dog used in my invention, while
Figures 4 to 9 inclusive show details of the various tumblers used in my lock.
My invention comprises essentially a lock housing of any suitable size or
material which is provided with the upwardly extending flange, B, which flange
in conjunction with two similar plates, A, forms my lock casing.
The flange, B, is secured to the plates, A, with the exception of one end, b,
thereof, which end of the flange is loose and operates as a spring, this flange, B,
being of spring metal. Secured to the plates, A, by means of a pin, 1, is the hasp, 2,
which has an end, 3, to form a lock seating as is shown.
The hasp is further provided with an extension, 4, which operates against the
spring end, b, to normally throw back the hasp.
Positioned at a suitable point within the casing is a shaft, 5, upon which shaft
are mounted seven tumblers, six of which for the sake of convenience are mutilated
as is shown in Figures 4 to 9 inclusive. The upper integral tumbler is numbered 6¹,
the succeeding one 71, the following one 8¹, succeeded by the tumblers 9', 10', 111
and 12, Each of these tumblers is provided with an incision, a The tumblers
numbered 101 and 121, however, are provided with projections, the tumbler, 10¹,
being provided with a downwardly extending hook, d, while the mutilated
tumbler 12, is provided with a stub projection, c. Each tumbler in addition is
provided with an opening, c, through which a pin, g, shown in Figure 1, is made
to pass in securing these tumblers, each to a bar, C, which bar is provided with
an operating button, D, as is shown in the drawing.
Each of these operating buttons is made to pass through an opening within
the flange, B, these buttons being held and guided within their openings. Upon
the inside each operating button is provided with a spring, 15, working against the
lower end of the button so that each button is normally held outwardly under
spring tension.
Pivotally secured within the lock housing is a lever, H, secured by means of the
pivot, 16, and to which is secured a bar, C¹ provided with the button, D. To prevent
"

page_text: these buttons from passing too far outward, each is provided with a projecting
pin, 17.
Projecting from the lever, H, is a housing, K, from which extends the dog, K',
which dog below is provided with a slot 20, as is shown in Figure 3. Working
within the housing, K, is a pin, E, which is provided at the rear with a flaring
head projecting beyond the housing and upon the inside with a pin, 21, and
between this pin, 21, in the bottom of the housing, K, is an ordinary expansion
coil spring, 22, to normally force this pin E, outward to form a spring catch.
Working adjacent to the mutilated tumblers is a sliding link, M, which is
provided with a central slot, 25, which near the rear is provided with the seat-
ing, 26, in front with the projecting nosing, 27, and at the rear with a pro-
jection, 29, provided with a seating, as is shown in Figure 1. This link is held
in position by means of a pin, N, and an ordinary spring, 30, to normally force
this link towards the series of tumblers. In its normal position, this sliding
link, M, is forced against the projection, e, of the tumbler, 121, as is shown in
Figure 1. In this position, the hook end, d, of the mutilated tumbler, 101, rides
within the slot, 25, and resting immediately within the seating, 26, as shown.
To open the lock it would be necessary to move the dog, K', with its connected
spring catching bar, E, out of the seating, 3. This, however, could not be done
unless the incisions, a, would all come within line so that this dog could find a
seating within the combined tumbler incisions permitting the escape of the hasp, 2.
The dog, K, is of a width equal to the combined width of all the tumblers.
While several hundred combinations can be made with a lock constructed as
described, I have shown one combination disclosing the instrumentalities as shown.
In this combination, referring now to Figure 2, where the line, &,, represents
the position of the dog, K', it would be impossible to unlock the hasp unless the
mutilated tumbler, 81, were carried towards the y side so as to bring its slot within
line of the tumblers, 61, 71, 91, 11 and 12. While the tumbler, 10', however,
would have to be carried towards the z side in order to bring about alignment.
This as shown would require the depression of the button marked, 8, as well as
a depression of the button marked, 10. Should any other button, however, be
touched it would of course, carry its connected tumbler out of proper alignment
and prevent the falling of the dog.
The arrangement of the tumblers without the operation of the link, M, would
comprise an ordinary simple lock which could be easily picked. However, by the
addition of the sliding link, M, the combinations are multiplied as well as made
very difficult in operation. Should for instance, the tumbler, 10¹, be touched at
any time, it would carry the link, M, forward so that the end, 27, would slide into
the seating, 20, and act as a bolt to lock the dog, K¹, and then even though all
the slots be in proper alignment it would be impossible to depress the releasing
button, 13, as the nosing, 27, would securely lock the dog, K.
Should the mutilated tumbler, 121, be actuated alone, it would by means of the
projection, e, force the link, M, outward, so that the circular seating shown would
engage the pin, 31, in which position the link would be locked against the pin.
This displacement of the link then would permit the passage of the hook, d, so
that the incision or slot within the mutilated tumbler 101, would be brought
into proper alignment.
If a lock were constructed and arranged precisely as is shown in Figures 1
and 2, the combination to unlock the same would be as follows:
Depress buttons, 8, 12, then 10, then release 12, and finally depress 13, when
the lock could be opened.
In referring to Figure 2, 8¹ would have been moved to bring its slot into align-
ment, next 12 would have been moved but this depression, was not made to bring
its slot into alignment, as this slot already was in proper position. but the tumbler
was operated so that the projection, e, would engage the, breast, 29, of the link, M,
to carry this link outward. The tumbler, 101, was next actuated, which movement
was permitted by virtue of the tumbler, 121, holding the link, M, outward and
after this tumbler had been brought into alignment it would be necessary to release

page_text: the button, 12, to bring its slot again into alignment, when by simply depressing
the releasing button, 13, the dog would fall into the slots or incisions permitting the
opening of the lock.
To facilitate the opening of the lock, the lock upon the one side is smooth and
upon the other milled or roughened.
To get new combinations, it is of course, understood that it is simply necessary
to change the position of the slots or incisions within the mutilated tumblers as
well as change the hook, d, and projection, e, in placing the same upon some other
tumblers.
The tumblers are mutilated for convenience so that the rods, C, may readily
work between the various tumblers.
This lock can be made of any suitable size, or material, and of course, a greater
or less number of mutilated tumblers could be used. So also, could another
link, M, be added if desired.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is;-
