Improvements in Locks.
I, CHARLES SHERMAN VAN AUKER, of St. Joseph, in the County of Buchanan,
and State of Missouri, formerly of Salt Lake City, in the County of Salt Lake and
Territory of Utah, United States of America, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention relates to locks, and particularly to fastenings for hasps and the
like. In fastening doors, mail pouches, &c., by providing a hasp with a slot
adapted to receive a staple, and, after the hasp has been placed over the staple,
passing the bolt of a padlock through that part of the staple which projects beyond
the hasp. The hasp must be first placed over the staple, then the padlock applied,
and, indeed, in many cases, the hasp and staple must be held together with one
hand while the lock is placed in position with the other, and even after this locking
has been effected, both the staple and the padlock bar are exposed so that it is not
difficult to file either apart. To obviate these difficulties locks have been formed
immediately upon the hasps and my invention consists in the arrangement of parts
in such locks, though, of course, it will be readily understood that the same
arrangement may be applied to other forms of locks.
My invention is illustrated in the accompanying drawings, in which-
Figure 1 is a view showing my lock in position for use with a staple.
Fig. 2 is a view of the lock with the upper plate removed to expose the working
parts; and
Fig. 3 is a section on line III-III, Fig. 2.
any
In the drawings, A is a hasp and B a staple, both of well known
construction. The hasp is provided as usual with a slot a for the reception of
the staple, and with relation to this slot a lock is so placed that its locking bolt C
passes across it, thus engaging the staple when in position for fastening.
As shown in the drawings, the back of the lock casing is formed by the hasp.
1, 2, 3, 4, are its outer walls, 5, 6, 7, 8, walls about the slot a, and c is the front
plate.
As before mentioned, one of the disadvantages of the method of locking by means
of the hasp, staple and padlock, is that the staple and padlock yoke are both so
exposed that either may be readily filed apart. In my present invention, however,
I make the slot a of such a width that when the staple is in place, little or none of
the bolt C is exposed, while the lock casing is made of such a height that the
farthest projecting part of the staple is beneath the surface of the plate c.
no filing or cutting of the bolt or staple is possible.
Thus
In the construction of the interior of the lock herein shown, the bolt C, provided
upon its outer end with the thumb cap d, moves in the walls 1 and 5, passes across
the slot a, and enters a recess x, formed for its reception in the wall 7. This bolt
is provided at that portion which slides between the walls 1 and 5 with two
grooves, e, f. A spring 9 acting to force the bolt C outward has one end bearing

page_text: against the wall 5, while the other end engages in the groove e.
The groove fis
for the reception of a suitable counter-bolt D, in the present instance held normally
in engagement with said groove by means of the tumbler E and spring F, this
counter-bolt D being released by a suitable key. It will be readily understood
that the lock casing may be formed, as here shown, directly upon the hasp, or the
lock may be made separately and fastened to the hasp in any convenient manner.
The operation of my lock is as follows: The spring g tends to normally force
the bolt C outward and thus release the lock, while the counter-bolt D is, because
of the spring F, normally pressed upward to engage with the groove f. As soon
as the counter-bolt D is disengaged from its groove, the bolt C will fly back.
Suppose, then, it is desired to lock the door to which my device is applied; it is
only necessary to swing the hasp over the staple, the bolt C being pressed outward
by its spring, and, when in the proper position, press upon the thumb cap until the
bolt is locked in position by the counter-bolt D entering the groove f. To release
the members it is only necessary to force back the counter-bolt with a suitable key,
when the bolt C will fly back and the door may be opened.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
--
1. A lock comprising a bolt, shoulders formed immediately upon said bolt, a
spring bearing at one end against the lock casing and at the other against one of
the shoulders of the bolt, and a counter-bolt adapted to engage with the other
shoulder; substantially as described.
2. A lock comprising a bolt, shoulders upon said bolt, a spring bearing at one
end against the lock casing and at the other against one of the shoulders of the
bolt, a counter-bolt adapted to engage with the other shoulder, a tumbler at one
end attached to the free end of the counter-bolt and at the other end connected to
the casing, and a spring bearing at one end against the casing and at the other end
against the tumbler; substantially as described.
Dated this 25th day of August 1893.
