A Hasp Lock.
I WILLIAM HUMPHREY WHEATLEY of 40 Chancery Lane in the County of
Middlesex, Patent Agent 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 :-
The invention consists in certain features of construction and combinations of parts,
as will be described, and pointed out in the claims.
Figure 1, is a detail view of the hasp.
Figure 2, a detail view of the staple and its fastenings.
Figs. 3 and 4 are detail views showing the hasp and its securing bolt.
Fig. 5, shows the pivot-stud for connecting the lock-case to the hasp.
Fig. 6 is a side view of the lock.
Figure 7, is a bottom plan view of the lock, the pivot-stud being also shown in
section.
Fig. 8 is a plan view of the lock, the top plate being removed and the pivot stud
being partly shown.
Fig. 9 shows the top plate of the lock, and Fig. 10 is a side view of the device as in
use.
The hasp A has its rear end slotted at a, and provided with studs al projected into
said slot from the side arms formed thereby. These studs a' fit and are secured in
slots a², formed in the head of bolt A' which in turn is journalled in the door or
other support. By this construction the hasp may be easily and securely connected
with the support, and when so secured has a free movement when detached from the
staple.
At or near its free end the hasp A has a slot a³, to fit over the staple B, which has
an opening b, and is provided with a notch 62, in the other side of its end bar b¹. The
pivot-stud Chas its portion 1 journalled and secured at 2 to the hasp, and has its
portion 3 made non-circular to prevent any turning of the lock-case thereon, and has
its head 4 formed to fit within the lock-case, and hold the same from detachment from
the pivot-bolt and through said bolt from the basp.
The lock D comprises a lock-case E, and a bolt proper, F, the case and lock
forming, practically, the bolt, as will be seen. Such parts E and F are rigidly
connected to the body of the case and the bolt proper, being usually formed integral.
The head of the bolt F is formed with a slot or slots, ff, which are extended in the
direction of its length and are arranged one in rear of the other, the rear slot f, having
an outlet f laterally at its forward end, the portion f2 of the bar forming a hook as
shown inost clearly in Figs. 7 and 8. The case E has in its back plate a slot
which
fits the portion 3 of the pivot-stud, and in such case I secure a spring-actuated
tumbler e arranged to engage the pivot-stud (when the bolt is moved forward to its
extreme forward position. This tumbler may be released from the stud C by means
of a key inserted through opening and properly turned to engage with the
tumbler.
It will be seen therefore, that by means of the pivot-stud C and the connection of
the lock-case therewith the bolt is pivotally connected with and also movable
longitudinally with reference to the hasp, by which means it may be first swung on its
pivot into engagement with the staple to form a temporary or what might be termed
a "latch" fastening, and then when desired, it may be moved longitudinally to cause
its portions adjacent to slot or slots to engage with the staple, as will be understood
from the drawings.

page_text: Having thus fully described and ascertained what my said invention is and
how the same is constructed and performed, I do hereby declare that what I claim
as my invention and desire to secure by Letters Patent, is :-
1. In a hasp lock, a hasp combined with a bolt pivotally connected with and also
having a longitudinal movement or adjustment along said hasp, and a tumbler
for securing such bolt in locked position, substantially as set forth.
2. The combination of the hasp having slot a and inwardly-projecting studs a¹ a¹,
and the bolt having its head formed with slots a² in its inner face or side, adapted
to receive the studs a' substantially as set forth.
a
3. The combination, with the hasp of the bolt having a lock case, the pivot stud
having portion 1, journalled to the hasp, a portion 3, fitting a slot in the lock-case,
and a head 4, and a tumbler supported in the case and arranged to engage the pivot-
stud, substantially as set forth.
4. The combination, with the staple of the hasp, and the bolt having the hook f²
and a slot or slots f, said bolt being movable pivotally and longitudinally with
reference to the hasp, and a tumbler for securing the bolt in locked position,
substantially as set forth.
5. A hasp-lock comprising the hasp, the pivot-stud C, having portions 13 and
head 4, the bolt having a lock case and a bolt proper, the latter having slots fand
hook f, and the lock-case being slotted at e to receive the pivot-stud, and a tumbler
supported in the lock-case and adapted to engage the pivot-stud whereby to secure the
bolt in locked position, substantially as set forth.
Dated this 30th day of November 1889.
