VORIES P. BROWN, OF SAN ANTONIO, TEXAS.
PADLOCK.
SPECIFICATION forming part of Letters Patent No. 482,070, dated September 6, 1892.
Application fled April 5, 1892. Serial No. 427,861. (No model.)To all whom it may concer:
Be it known that I, VORIES P. BROWN, a
citizen of the United States, residing at San
Antonio, in the county of Bexar and State of
5 Texas, have invented a new and useful Lock,
of which the following is a specification.
This invention relates to locks; and it has
for its object to provide an improved lock
which, while simple in construction and oper-
io ation, is at the same time so constructed as to
be proof against the possibility of picking by
unauthorized persons, and one which when
unlocked will automatically release itself
fromthe object and which locks of itself when
15 sprung together. With these points in mind
the lock is particularly well adapted, both on
account of its construction and the compara-
tively small compass which it occupies, for
use upon halters or other devices of similar
20 character, which must of necessity be securely
fastened to prevent theft of the object se-
cured by the lock.
With these and many other objects in view,
which will readily appear as the nature of the
25 invention is better understood, the same con-
sists in the novel construction, combination,
and arrangement of parts hereinafter more
fully described, illustrated, and claimed.
In the accompanying drawings, Figure 1 is
30 a perspective view of a lock constructed in
accordance with this invention. Fig. 2 is a
vertical sectional view of the same, showing
the lock open. Fig. 3 is a similar view closed.
Fig. 4 is a detail in perspective of the lock-
35 ing-lever. Fig. 5 is a similar view of the key-
guide plate. Fig. 6 is a similar view of the key.
Referring to the accompanying drawings,
A represents a rectangular lock-casing in-
closed.by the cap-plate B, having an ordinary
40 keyhole b near one end thereof and is con-
nected at its lower end with the bolt b', lo-
cated beyond the body of the casing and pro-
viding means for the accommodation of a
strap, chain, or the like, which may be con-
45 nected therewith and the object to be secured.
Pivoted at C in one corner of the casing A
is the shackle D, the other end of which
works through the opening d in the opposite
corner of the casing and is provided with a
50o locking-perforation d', which is engaged by
one end of the spring-actuated locking-lever
E. The said locking-lever E is centrallypiv-oted at e within said casing and is provided
at one end with a right-angularly-disposed
locking-pin F, which is normally pressed to- 55
ward the side of the casing by the leaf-spring
G, secured to the opposite side of the casing
and pressing against said locking end of the
lever. The other end of the locking-lever E
works over the face of the slotted key-guide 6o
plate H, secured upon the pin h near one side
of the casing, while the opposite end of said
plate rests upon the shoulder I at the oppo-
site side and in one corner of the casing.
The key J is provided with a wing j, which 65
when the key is inserted in the lock is de-
signed to pass into the slot h' of said plate H,
and engage one end of the locking-lever E,
which thus throws the locking-pin at the
other end of said lever out of the perforations 70
d' in the shackle, which is thus released and
is automatically shot from the casing by the
spring-actuatedejector-boltK. Thesaidbolt
K works along one side of the casing, directly
under the shackle-opening d in the top there- 75
of, and is provided with a stem k, working
through the shoulder I of the casing, while
interposed between said shoulder and said
bolt is the actuating-spring L, normally press-
ing the same toward the opening d'. The 80
plate K is further provided with the opposite
shoulders k', working on each side of the lim-
iting-pin M, projecting from the bottom of
the casing. When the locking-lever is thrown
out of engagement with the perforation of 85
the shackle, as already described, the spring-
actuated bolt-bearing against the end of the
shackle, immediately shoots the same from the
casing and holds the locking end of the lever
away from the shackle-opening d. By press- 90o
ing the shackle through the opening d the
bolt K is pressed below the locking-pin F,
which immediately engages the perforation
of the shackle and locks the same.
The construction, operation, and many ad- 95
vantages of the herein-described lock are now
thought to be apparent without further de-
scription.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat- ioo
ent, is-
In a lock, the casing having an opening in
one end thereof, a shackle pivoted at one end
to said casing and having a locking-perfora-
