I ARTHUR BUTLER draughtsman of 21 Rock-view Road Burmantofts Leeds in
the County of York do hereby declare the nature of this invention to be as follows
After making the cases of Pad and other locks in the usual way, I make the lock
proper to consist of the following parts, First I provide a catch or bolt the fore part
of which having a upper and lower jaw or lip similar to what is commonly known as
a screw key or wrench the hinder part having two projections, the upper one to
prevent or rather to hold the levers when unlocked the lower one to prevent the
turning of a false key. I also provide one or more levers, which prevent catch from
releasing bow when locked, the locking being accomplished by pressing bow into case
of lock the end of bow first coming in contact with bottom lip of catch thereby
turning said catch upon its axis and causing the upper lip to enter hole provided in
bow, and the lever or levers being pressed forwards by a spring the bow is thereby
made secure. The opening being accomplished as follows, by a proper fitting key
I lift the said lever or levers to a certain height and at the same time in a lateral
direction thereby releasing hinder part of catch and allowing bow to be lifted in the
usual way, the catch and levers remaining in unlocked position. To more fully
understand the aforesaid invention, see accompanying drawings, Fig. 1 representing
lock as locked Fig. 2 unlocked Fig. 3 key, for the following see Figs. 1 & 2. A. A. is
catch B. B. levers, C. C pin on levers which slide under hinder part of catch thereby
preventing said catch froin being turned when locked, D. D is spring which push levers
into locked position The principle as herebefore described I apply to other locks such
as locks for Boxes, Desks, and Books, &c. as well as for Pad locks.

page_text: I ARTHUR BUTLER of 21 Rock View Road Burmantofts Leeds in the county of
York, Draughtsman 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:—
After making the cases of my pad-locks and other locks in the usual way I proceed
to make the locks proper which consist of the following parts. First, I provide a
catch or bolt the fore part of which having two projecting jaws engaging the bow,
shackle or other fastener, the hinder part of the said catch having one or two pro-
jections, one on the upper side and one on the under or bottom side which prevents
the use of other than the proper fitting key. I also provide a lever or levers to secure
said catch when locked. The locking in the case of padlocks and the like being
accomplished by merely pressing the shackle or bow downwards or towards the case
of the lock, when the said catch will turn and the lever or levers will move in a lateral
direction thereby securing the catch; the stump upon which the said catch turns
being the stump by which the levers are made secure when locked. The unlocking
being accomplished as follows the proper key is inserted and raises the levers the
required height backwards in a laterial direction thereby releasing the catch, and on
the bow or shackle being raised or the fastener being moved in a lateral direction the
lock is opened or unlocked. I also apply the above said principle to pad locks,
locking at the tail end heel of the shackle and also to other locks such as locks for
Travelling Trunks, boxes, desks, books, etc.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a front elevation shewing the inside of a padlock locked, made according
to my invention.
Fig. 2. is a front elevation shewing the padlock unlocked.
Fig. 2 shews modification with bow or shackle altered and the projection a²
dispensed with.
Fig. 3. is a front elevation shewing a pad lock locked, with my improvements
applied to the tail or heel of the shackle bow or fastener.
Fig. 4. is a similar view unlocked.
Figs. 5 and 6. are elevations shewing my improvements applied to locks for
travelling trunks, boxes and other suitable locks, and have a long rod and two
fastenings towards each end of the trunk.
Figs. 7 and 8 shew the central form of trunk fastenings locked and unlocked with
my invention applied.
Figs. 9. and 10. shew
Fig. 11. shews stump

upon the catch instead of upon the lever as heretofore.
having two jaws a' and a and projections a³ and a' at its

page_text: other end, b is the lever or levers, d is the spring for the catch, e is the spring for the
lever, is the stump or pin upon which the catch turns and secures the lever when
locked, g is the stump or pin upon which the lever or levers move, is the stump ΟΙ
pin upon the lever or levers which prevents the catch from being turned when locked,
k is the bow, shackle or other fastening portion of the lock. The locking is caused
by simply pressing down the bow or shackle k in the case of padlocks and the like,
which comes in contact with the lower projection a² and moves the catch a and the
lever forwards bringing the projection a into the hasp or fastening, the lever b
securing the catch in position when locked. Figs. 5 and 6. shew the locks in locked
and unlocked positions for fastening or locking trunks, or boxes by means of the bolt
or rod k which is moved by hand in a lateral direction and automatically locks or
fastens the box to which it is attached by its projection turning the catch a upwards
sufficiently high to allow the lever b to slide under the tail end of the catch a, the
lever being moved in a lateral direction by the spring e. The unlocking is
accomplished by inserting the proper key which raises the lever or levers b, the
required height and at the same time in a lateral direction thereby releasing the said
catch which releases the fastener or bolt k, the lock being then opened or unlocked.
The projection is a safety catch to prevent the opening or unlocking of the lock by
the use of other than the proper key.
Figs. 7 and 8, shew locks with single hasp fastenings which operate exactly similarly
to Figs. 5 and 6, the hasp being turned down, its projections are inserted into the
eyes of the lock and the hasp is moved on its hinge in a lateral direction so operating
the catch and lever as before described in Figs. 5 and 6.
There may he one or more catches and levers with their safety projections employed
as required.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I would have it understood that
I do not claim any particular hasp arrangement or limit myself to any number of
catches but what I do claim is :-
(1). The self locking arrangement of pad locks and other locks for trunks, boxes
or desks and the like appliances substantially as shewn and described.
(2). The combination of the catch or catches a, lever or levers b, with their
projections constructed substantially as and for the purposes shewn and described.
