I GEORGE HARRISON of Green Lane Walsall in the County of Stafford Manufacturer
do hereby declare the nature of my said invention to be as follows:-
My invention has for its object improvements in padlocks which are thereby more
simply constructed with a less number of separate parts and with loss cost than
previously in the following manner.
I make padlocks both for tumbler and back spring locks with the cheeks-which
guide the bolt and the cap or bridge form one piece or strip of sheet or other metal
thus avoiding the expense of punching holes and of fitting the parts together. I take
one strip of metal and bend over therefrom at each end a check piece which is secured
to back plate in the usual or any suitable manner. This piece which forms substan-
tially a bridge with the two rests or pillars has suitable slots or holes cut therein for
the bolt i.e. a hole in the front cheek and a slot hole in the back cheek. The top edge
of the bridge is hollowed out.

page_text: J, GEORGE HARRISON of Green Lane, Walsall, in the County of Stafford, Manufacturer,
do hereby declare the nature of my said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
This invention has for its object improvements in padlocks which are thereby more
simply constructed with a less number of separate parts and with less cost than
previously, in the following manner :-
I mako padlocks both for tumbler and back spring locks with the checks—which
guide the bolt and the cap or bridge from one piece or strip of sheet or other metal
thus avoiding the expense of punching holes and of fitting the parts together. I take
one strip of metal and bend over therefrom at each end a check piece which is secured
to the back plate in the usual or any suitable manner. This piece which forms
substantially a bridge with the two rests or pillars has suitable slots or holes cut
therein for the bolt i.e. a hole in the front check and a slot hole in the back check.
The top edge of the bridge is hollowed out.
In order that my invention may be clearly understood and more easily carried into
practice I have appended hereunto a sheet of drawings upon which I have illustrated
its application to one kind of lock though the invention is applicable to any kind of
padlock where such parts as form the subject of my invention are required.
Figure 1 shows the back plate A of a padlock and the side or distance piece C with
the face plate removed so that the inside can be seen.
Figure 2 is an elevation of the bridge piece E shewing a small portion of the back
plate A.
Figure 3 is a view of the plate partly worked from which the bridge E is
formed.
From Figure 3 it will be seen that the plate A is prepared in a flat state and
punched with the holes e, es, e and e and shaped around its edge in order that it may
be prepared to attach to the foundation or back plate A when bent into the shape as at
Figure 2 where it is seen as a bridge. The parts e³ and et in Figure 2 forin ears
having the holes e and by which the bridge is attached to the foundation or back
plate A. The parts e¹ and e form the sides or abutments of the said bridge and the
parte the top plate. The bolt B works in the slot e the point passing through the
slot e. It will thus at once be seen that the bridge and sides are formed from one
completo instead of several pieces and thus a good deal of rivetting and working is
avoided besides the production of a better bridge than by the old plan. It will be
evident to practical men that this bridge may be used for any kind of locks where
such bridges are required the one shewn being only an illustration of its application.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improvements in padlocks of the bridge E manufactured from one solid plate
as shown at Figure 3 in such a manner that it may be secured to the back plate thus
forming one complete whole substantially as and for the purpose herein set forth and
illustrated upon the drawings.
