Year: 1895

page_text: Date of Application, 19th Jan., 1895
Complete Specification Left, 4th Sept., 1895-Accepted, 5th Oct., 1895
I, ENOCH PINSEN, of the Firm of Enoch Pinsen & Co., Brass Padlock Makers,
Willenhall, in the County of Stafford, do hereby declare the nature of my said
invention to be as follows:-
My invention has for its object improvements in padlocks and refers more
particularly to cheap brass padlocks whereby they are cheapened in production and
improved in utility.
In carrying my invention into effect I stamp or otherwise cut out the key of the
padlock from sheet metal and with a stud projection upon the end. The keyhold
of the padlock is placed horizontally and a hole is formed in the back plate of the
padlock into which the beforementioned stud fits when the key is in position. The
key is also provided with a slot of the required width to just fit the front plate of
the padlock.
By these means the key turns very smoothly and the necessity for a barrel ou
the back plate is obviated. The key may be stamped with projecting wards and
acts as in an ordinary lever lock.

Improvements in Padlocks.
I, ENOCH PINSEN, of the Firm of Enoch Pinsen & Co., Brass Padlock Makers
Willenhall, in the County of Stafford 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 :-
My invention has for its object improvements in padlocks and refers more
particularly to cheap brass padlocks by which the cost of production is considerably
reduced.
In carrying my invention into effect I stamp or otherwise cut out the key of my
padlock from sheet metal and with a stud projection upon the end. The key hole
of the padlock is placed horizontally and a hole is formed in the back plate of the
padlock into which the beforementioned stud fits when the key is in the lock. The
key is also provided with a slot of the required width to just fit the front plate of
the padlock. By these means the key turns very smoothly and the necessity for
a barrel on the back plate is obviated the key may be stamped with various slots
and projections to suit the wards and acts as in an ordinary lever or other lock.
in order that my invention may be clearly understood and more easily carried
into practice 1 have appended hereunto a sheet of drawings showing my invention
applied to a pad-lock of ordinary or lever construction as my invention is not
confined in its application to the internal construction whether lever tumbler or
otherwise.

page_text: Figure is a front view of a padlock showing the outside or front of same.
Figure 2 is a similar view to Figure 1 but showing the back of the lock.
Figure 3 is a side view of the key.
Figure 4 is an edgewise view of the key as seen at Figure 3.
The drawings are larger than the locks most generally made of this kind so as
to show the parts clearly.
Referring to Figures 3 and 4 which show the key, K, in two views it will be
noticed that there is a projecting pivot K so that when the key is passed into the
front plate A and has passed into the body of the lock so that the slots and
projections are right for operating upon the levers and other parts the projection k¹
is pivoted in the hole 6 in the back plate B thus forming an accurate centre
bearing upon which the flat plate key turns. When the key K is in this working
position the notch allows the plate as outside the hole a¹ to be in the said
slot thus affording in combination with the pivot sufficient steadiness to allow
the key to be operated easily. There is a thickened part 2 on the key formed
on the stamped key by setting or staving it up so that the key is protected
against falling into the horizontal slot a2 when at first entered into the lock.
Though these locks are generally made from sheet brass they may of course be
composed of any other metal or suitable material.
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 :-
1st. The improvements in padlocks consisting of projecting part k¹ operating in
the pivot hole b¹ in combination with the slot which embraces the plate a³
substantially as and for the purpose herein set forth and shown upon the drawings.
2nd. The padlock key K having the projection k¹ and slot k³ and thickened
part k².
