We, NOAH FELLOWS of N° 6 Kenton Road South Hackney in the County of
Middlesex Zinc Worker and HENRY WINKLEY of N° 23 Coopersale Road, Homerton
in the said County of Middlesex, Builder, do hereby declare the nature of our
invention for AN IMPROVEMENT IN STRIKING PLATES, CATCHES, BOX-STAPLES AND
THE LIKE FOR LOCKS AND LATCHES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to an improvement in striking plates catches, box-staples
and the like, for locks and latches, the object of the said invention being to render
the same more durable, less liable to breakage and easier in use than heretofore.
In carrying out our invention, we construct the striking plate, catch, box-staple
or the like with a small anti-friction ball The said anti-friction ball may be made
of any suitable metal, but we prefer to make it of steel, hardened, so as to reduce
the wear of the same to a minimum.
The said anti-friction ball is mounted and held between two lugs or projections,
each of which is recessed to form a seat for the said anti-friction ball.
The said lugs or projections are fixed to the said striking plate or the like in any
suitable manner, but in such a position, that when the bolt of the lock or other
fastening, which it is desired to engage with the said striking plate or the like is
brought into engagement with the same the said bolt is caused to impinge against
and ride over, at the same time imparting a rolling motion to the said antifriction
ball, behind which it is held in the ordinary manner.
By this construction any damage to the striking plate or the like is prevented
and at the same time the engagement of the lock or latch with the said striking
plate or the like is rendered much easier than heretofore.
For ordinary locks and latches we prefer to use a single anti-friction ball, but in
cases where locks having larger bolts are used we prefer to use two or more
anti-friction balls so as to form a better bearing surface for the said bolts when
rolling or riding over the said anti friction balls.
To enable our invention to be carried into practice, we will proceed to describe
the same by reference to the accompanying drawing in which, Figure 1 represents

page_text: a front elevation of a box-staple with our improvement applied thereto, the said
box-staple being shewn fitted in place. Figure 2 represents a side elevation of the
same and Figure 3 represents a horizontal section on the line x x of the box-staple
shewn in Figure 1, but shewing in addition a portion of a door with a lock thereon,
in engagement with the said box-staple Figures 4. 5, and 6 represent similar views
to Figures 1, 2 and 3 with the exception that a striking plate for a mortise lock is
shewn with our improvement applied thereto. Similar letters of reference in all
the figures represent similar or corresponding parts.
Referring to Figures 1.2 and 3 a represents a box-staple of ordinary construction,
fitted to the framing A of a doorway, and b represents the striking plate of the said
box-staple a. The said box-staple a and striking plate b. are notched or cut away
as shewn at c. At the top and bottom of the said notch c are fitted in any suitable
manner two lugs or projections & and e respectively, the said lugs being recessed on
their adjacent faces to adapt them to receive and hold the anti-friction ball f. As
shewn in Figure 3. B represents the door and C the bolt of the lock, the said bolt
(when the door is being closed) being caused to ride over the antifriction ball f into
the position shewn. In Figures 4. 5, and 6 which shew our improvement adapted
for use with a striking plate for a mortise lock as herein before described.
b represents the said striking plate which is constructed with the ordinary
extension piece g which is bent in the form shewn in Figure 6. The said striking
plate is notched or slotted at c, the said notch or slot extending into the piece gas
shewn. At the top and bottom of the said notch or slot c are fitted two lugs d and e
respectively, and serving the same purpose as those shewn in Figures 1. 2 and 3.
It will be obvious that we can use our improved striking plate or the like in either
a horizontal or vertical or in any other position to suit the position of the bolt
which engages with it.
Although we have only shewn our improvement constructed and applied to two.
different forms of striking plates or the like, it will readily be understood that we
can construct and apply it in other ways without departing from the spirit of our
invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what:
we claim is
In a striking plate or the like the use of one or more friction balls, substantially
as and for the purposes herein before described and represented in the accompanying
drawing.
