PROVISIONAL SPECIFICATION.
Improvements in Roller Staples for Use with Latching Bolts of
Door Looks and Latches.
1, ERNEST AUGUSTUS TILDESLEY, of Gower Terrace, Gower Street, Willen-
hall in the County of Stafford, Clerk, do hereby declare the nature of this invention'
to be as follows:-
This invention relates to that class of staples, for use with latching bolts of
door locks and latches, which are each fitted with a roller against which the latch
bolt strikes as the door is closed in, whereby friction is greatly reduced. Such
staples, as heretofore constructed, are provided each with a short roller placed
out of the middle of the staple, lengthways in position to suit a latch bolt
striking either right or left hand as the case may be, and such staples are there-
fore what is technically known as single-handed only.
Now, this invention has for its object to adapt such staples for use, alternatively,
with a latch bolt striking either hand; aud to improve the means of mounting the
rollers in place.
;
A roller staple, constructed according to this invention, has the roller of such
length and placed in euch position lengthways of the staple (preferably extending
an equal distance each way from the middle of the staple) that it approaches
sufficiently near to each end of the staple to ensure that the latch bolt will strike
properly against the roller whichever hand the staple is used.
If the roller is shorter than between the inside of the ends of the staple,
it may be mounted therein in the usual or any convenient manner; but a
special feature of the invention consists in making the roller the whole length of
the staple between the inside of the ends, but so as to be capable of turning
easily between such ends, and mounting it, oither upon a pair of pivots screwed
through the ends of the staple, or upon a pin passed through such ends and
through the whole length of the roller. Ears through which the pivots or pin
pass or passes are formed out from the ends of the staple to bring the roller
forward the required distance. Whether the roller is made the whole length
between the ends of the staple, or is otherwise adapted as above described
to make the staple double-handed, it may be placed in such position that the
latch bolt and the locking bolt (if such is used) shoot in immediately behind it.
In such case the edge of the front plate of the staple is kept back to clear the
roller.

Improvements in Roller Staples for Use with Latching Bolts of
Door Locks and Latches.
I, ERNEST AUGUSTUS TILDESLEY, of Gower Terrace, Gower Street, Willen-
hall in the County of Stafford, Clerk, 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 :-
This invention relates to that class of staples, for use with latching bolts of
door locks and latches, which are ench fitted with a roller against which the latch
bolt strikes as the door is closed in, whereby friction is greatly reduced. Such
staples, as heretofore constructed, are provided each with a short roller placed
out of the middle of the staple lengthways, in position to suit a latch bolt striking
either right or left hand as the case may be, and such staples are therefore what
is technically known as single handed only.
Now, this invention has for its object to adapt such staples for use, alternatively,
with a latch bolt striking either hand; and to improve the means of mounting the
rollers in place.
A roller staple constructed according to this. invention has the roller of such
length, and placed in such position lengthways of the staple, that it approaches
sufficiently near to each end of the staple (preferably extending the whole
distance between the inside of the ends thereof) to ensure that the latch bolt will
atrike properly against the rollert whichever band the staple is used.
.
If the roller is shorter than between the inside of the ends of the staple it may
be mounted therein in the usual or any convenient manner; but a special feature
of the invention consists in making the roller the whole length of the staple
between the inside of the ends and mounting it.oither upon a pin passed through
such ends and through the whole length of the. roller, or upon a pair of pivots
Borewed through the ends of the staple.
A roller staple made double-handed according to this invention is shewn, in the
form in which I prefer to construct it, by the drawings herewith, of which
Figure 1 is a front elevation thereof with the upper part of the roller and the
upper of the pair of ears, hereinafter described, shewn in section.
Figure 2 is a view of the staple as seen looking in the direction of the arrow a
Figure 1.
Figure 3 is a transverse section through the staple; and Figure 4 is an end
view thereof.
'
The roller A consiste, conveniently, of a brass or other.metal. tube into the ends
of which are brazed plugs or discs such as b; and to facilitate the fixing of the
discs in place the interior of each end of the roller is rhymered out to leave a
shoulder against the inner end of which the plug is stopped when placed in
position for brazing. Holes are bored through the plugs to form the journals of
the roller. Ears c are formed in the same piece of sheet metal as the staple,
being outward projections or continuations of the ends d thereof, or such cars
may be inade separately from the staple and be subsequently fixed thereto; and a
pine is passed through the cars and through the plugs b, and is riveted over at
each end. The roller thus turns upon the pin e, and as the roller extends the
whole length between the cars c such roller is adapted for use with the latch bolt
of a door lock or latch whichever hand the staple is used for.
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 :-
1. A roller staple for use with the latching bolt of a door lock or latch, having

page_text: the roller of such length and placed in such position lengthways of the staple
that it approaches sufficiently near to the ends of the staple to ensure that the
latch bolt will strike properly against the roller whichever hand the staple is used,.
substantially as described.
2. A roller staple for use with the latching bolt of a door lock or latch having
the roller extending the whole distance between the inside of the ends of the
staple and thereby made double-handed, substantially as described.
3. A double-handed roller staple having ears, such as c, formed out from the
ends thereof, and a roller extending the whole distance between such cars and
pivoted upon a pin, such as e, passing through the ears (or upon pivots screwed
through the ears), substantially as described and shewn by the drawings
berowith.
