PADLOCK
James A. Cox. Santa Fc, N. Mex.
Application March 1, 1937, Serial No.`128`,537
2 Claims.
This invention relates to padlocks and has for
the primary object the provision of a device of
this character which will exclude rain to prevent
the movable parts lwithin the lock body 'from
rusting and becoming inoperative or to prevent
the accumulation of water therein to freeze in
cold Weather and interfere with the operation
of the movable parts.
With these and other objects in View, this in
l l) vention consists in certain novel features of con
struction, combination and arrangement of parts
to be hereinafter more fully described and
claimed.
For a complete understanding of my invention,
reference is to be had to the following descrip
tion and accompanying drawing, in which
Figure 1 is a vertical sectional View illustrat
ing a padlock constructed in accordance With
2O
my invention.
Figure 2 is a sectional view taken on the line
2-2 of Figure 1.
Figure 3 is a sectional View taken on the line
3-3 of Figure 1.
Figure 4 is a sectional View taken on the line
25 4-4 of Figure 1.
Figure 5 is a plan view illustrating a key for
operating the padlock.
Referring in detail to the drawing, the nu
meral I indicates the padlock outer shell or body,
the same being of substantially rectangular lon
3O
gitudinal and transverse section, and having a
chamber 2 opening through the bottom. The
body l has a recess 4' disposed laterally of and
communicating with the chamber 2 and located
35 in the lower portion of the body. A passage 5
is formed in the body and extends from the top
of the body to the recess 4’ to receive a shackle 5.
The shackle 6 includes leg portions 'l and 8
and the leg portion 8 is of a greater length than
40 the leg portion 'l and is received in the passage
5 and enters the recess 4' while the leg portion
l may move into and out of a. notch or recess 9
formed in the top Wall of the body. The leg 1
oi" the shackle 6 when moved out of the recess
45 9 permits the shackle to be readily adapted to
a keeper. The leg portion 8 of the shackle is free
to slide in the passage 5 and also rotate. How
ever, the leg portion 8 has a comparatively tight
fit with the walls of the passage 5 to exclude
50 moisture, rain or the like from the recess 4'. -
A block or support l0 is mounted in the cham~
ber 2 and has formed therein a key opening or
passage Il, one end of which opens through the
bottom of the support. The support is provided
55 at the bottom with a flange 4 which ñts snugly
against‘the bottom edge of the shell or body
I to prevent entry of water into the chamber
2, Yin the body. Rivets or other connectors I2
are passed through the body I and support In
to rigidly secure the parts together. Formed on Ul
the support ID are guides I3 and I4 and which
are arranged -at'right angles to each other. A
locking bolt I5 is slidably supported by the guide
I3 and the guide I4 slidably supports a member
I6 which parallels the leg portion 8 of the shackle 10
and is connected thereto by a link Il. The leg
portion 3 of the shackle is acted upon by the
spring I8 and the member I6 is acted upon by
a spring I9. The springs I8 and Ill urge the
leg portion 8 of the shackle 6 and the members
I6 in the same direction. The spring acting
on the leg portion B of the shackle disengages
the leg portion 'l from the Arecess 9. A spring
20 acts on the locking bolt I5 to urge the same
in a position to overlie the member I5 and to
retain said member against movement under
the influence of the spring I9. The member I6
being held in the position stated by the locking
bolt holds the shackle 6 or the leg portion 8
from movement under the action of the spring
I8 and with the leg portion 'I extending into
the recess 9.
Formed in the support I0 is a chamber 2I in
which is-pivotally mounted a series of superim
posed tumblers 22 each having a slot 23 in one
end and a key slot 24 partially surrounded by
a shoulder 25. The slots 23 open outwardly to
the ends of the tumblers and are provided with
branches 26. A pin 21 is secured to the locking
bolt and extends through the slots 23 and when
the locking bolt overlies the member I6 the pin
occupies the branches. 26 preventing the locking
bolt from being retracted from engagement with
the member I6, consequently securing the shackle
6 against being moved to a released or unlocked
position. Leaf springs 28 act on the tumblers to
position them so that the pin 21 enters the
branches 26 of the slots 23. The locking bolt has
a key opening 29 and located adjacent thereto
is a shoulder 30. A key 3| is provided for actu»
ating the tumblers so asV to position said tumblers
with the pin 21 lying in the slots and out of the
branches. The key 3| also extends through the
key opening 29 of the locking bolt wherebyY the
same may be retracted against the action of the 50
spring 30 by the rotation of the key. The key
has projections or bits for the actuation of the
tumblers and the sliding bolt by engaging the
shoulders 25 and 30. Thus it will be seen that
this padlock is simple to actuate by a key and 55

when locked it will eiîectively prevent the shackle
from being moved into an open position. Fur
ther, it is to be noted that the construction of the
body and the connection of the shackle thereto
is such that water and moisture will be eX
cluded from the Working parts inside of the body
chamber and opening outwardly through a face
of the body, said body having a recess, a shackle
including leg portions, with one of said leg por
tions entering the chamber by Way of said pas
sage and the other leg portion adapted to be
moved into and out of the recess by sliding and
rotating said shackle, a member slidable in the
chamber, means connecting said member to the
shackle, spring means acting on said shackle
and member, a support in said chamber and hav
ing a key passage to receive a key, a locking bolt
slidable in said chamber to engage said member
either when the shackle is open or closed.
What is claimed is:
l. A padlock comprising a body having a cham
10 ber and a passage communicating With said
chamber and opening outwardly through a face

tions entering the chamber by way of said pas , for securing the shackle in a locked position and
15 sage and the other leg portion adapted to be having a key opening, a spring acting on said
moved into and out of the recess by sliding and locking bolt, tumblers pivotally mounted on said 15
rotating said shackle, a member slidable in the support and having slots provided with branches,
chamber, means connecting said member to the a pin secured to the locking bolt and extending
shackle, spring means acting on said shackle and into said slots, springs acting on said tumblers
20 member, a support in said chamber and having to position the latter to receive the pins in the
branches of said slots, said tumblers having 20
a key passage to receive a key, a locking bolt slid
able in said chamber to engage said member for key openings to receive the key whereby the tum
blers may be actuated by said key and the bolt
securing the shackle in a locked position and hav
slid by the rotation of the key with the pin
ing a key opening, a spring acting on said lock
ing bolt, and tumblers carried by said support moving in the slots of the tumblers to free the
member connected to the shackle and permit 25
