Improvements in Punches and Eyelet Fasteners.
I, SAMUEL LEAROYD of Sherwood House in Huddersfield in the County of
York, and of 12 Coleman Street in the City of London, Solicitor, 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:
In the application of various kinds of fasteners and eyelets it is very often
necessary that holes or incisions should be made in the paper or other materials to
receive the eyelets and fasteners and that means should be provided to fix such
eyelets and fasteners. It has hitherto been the custom to make such perforations
with a knife or similar instrument, or a mechanical punch. This is however
expensive and cumbersome.
Now the object of my invention is to simplify and cheapen the tools required to
be used and will be readily understood by reference to the accompanying drawings,
in which,
Figure 1 is a vertical section of my improved punch for piercing holes, and for
fixing the eyelets or fasteners.
Figure 14 is a plan of the same shewing the eyelet fixer.
Like letters of reference indicate like parts in the figures.
The punch shown in Figure 1 consists of a wooden handle A to which is attached
a nut threaded to receive a quick screw D, this latter being provided at its
lower end with a hollow cylindrical cutter F, having an outlet a in its upper portion
to discharge the cuttings. A spring B located in a recess b in the handle A, tends
to thrust the screw outwards and return the same after it has been depressed in
working the tool. A head e on the screw retains it in the handle against the
pressure of the spring. This latter however may be omitted and the screw returned
by its own weight. The cutters may be made of various sizes so as to be inter-
changeable and caps provided for covering them over. I may also make the nut C
split so that the motion of the screw may be retarded or regulated by the pressure
of the hand or other means.
To operate the punch, the handle A. is held firmly so as to prevent turning, and
the cutter forced downwards on the papers or other articles to he perforated. In
doing so the screw D will be caused to rotate, and also the cutter F, the latter
entering the papers or other articles and forming a neat and sharp circular hole.
It will be obvious that this form of punch is equally applicable to be attached to a
lever and to pincers and tweezers and I do so apply it when desired. By using
a stronger spring and a slower pitched screw the size of the tool may be materially
reduced. Figure 1 shows the crown or head of the handle A with the eyelet
fastener. The stud ; enters the eyelet the annular recess K resting upon the rim
of the neck of the eyelet, which is then forced or crushed down by the pressure of
the hand. When desired a quick screw and a spring may be attached to the top
of the handle A so as to assist the pressing of the eyelet by the stud j and recess K,
or in some cases I arrange one spring to work within another or larger spring so
as to operate at each end of the handle. I may also use the spring alone or the
quick screw alone, or both in combination. The eyelet closing stud may be placed
at the top of the handle as shown, or at the side of it.

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 1
claim is :-
1. In a punch for papers or other materials such as described, a handle
provided with a nut engaging a screw having at its outer end interchangeable
cutters, and a spring tending to return the said screw to its normal position, and
with or without a stud to fix the eyelets or fasteners, substantially as described
with reference to Figures 1, and 14 of the accompanying drawings.
2. The combination of a screw either with or without a returning spring, inter-
changeable cutters attachable thereto, and a split regulating nut engaging the
screw, all substantially as and for the purpose specified.
Dated this 20th day of February 1896.
