PROVISIONAL SPECIFICATION.
An Improved Machine for Piercing Holes in Wood or other
Material.
I GEORGE WILLSHIRE JOHNS of 9 Ambler Road, in the Parish of Islington,
in the County of London, Mechanic, do hereby declare the nature of this invention
to be as follows :-
My invention consists of a device for piercing in parallel laths of wood a series
of holes for the insertion of wire pins, at any required distance.
My plan is to use a series of steel awls of the shape of the hole required
attached to a sliding rail plate, operated by levers or other means, placed in an
iron frame at right angles to a series of parallel laths of wood, placed edgeways
in a sliding tray fitted to an iron tablestand, so that the laths in the tray may
pass under the awls. These awls, being fixed to the under-edge of the sliding
rail plate, would, when brought down by levers or other means, pierce into the
centre of the thickness of each lath to the depth required.
A lever or presser-
foot would be attached to the irou frame parallel to the sliding rail plate to
prevent the laths being displaced in the sliding tray when the awls
withdrawn.
are
The principal feature in this improvement is the rapidity and accuracy with
which holes can be made in laths, solid pieces of wood or other material.

An Improved Machine for Piercing Holes in wood or other
Material.
I, GEORGE WILLSHIRE JOHNS, of 9 Ambler Road, in the Parish of Islington,
in the County of London, Blind Manufacturer, 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 :-
My invention consists of a device for piercing in parallel laths of wood a series
of holes at any required distance, for the insertion of wire or other pins.
My plan is to use a series of steel awls of the shape of the hole required,
attached to a sliding rail plate operated by screws or other means. This rail
plate is placed in a metal frame at an angle to a sliding tray fitted to a tablestand
of iron or other material. Laths of wood are laid edgeways and lengthways in
the sliding tray and thus passed under the awls. When brought down by screws
or other means, these awls, being attached to the under edge of the sliding rail
plate, pierce into the centre of the thickness of each lath to the depth required.
Other material, besides laths of wood, may be placed in the sliding tray and
pierced in the same way.
A lever or presser foot moving parallel to the sliding tray is attached to the
metal frame by means of two pivots, to prevent the laths from being displaced in

page_text: the sliding tray when the awls are withdrawn. Clips may be placed at intervals
across the laths in the sliding tray for the same purpose. I may attach transverse
pressure screws to the sliding tray to press the laths together, so that each one
may be brought directly under the corresponding steel awl.
The sliding tray may be fitted with grooves or ribs to hold one or more laths,
in order that each lath may be more accurately pierced.
The principal feature in this improvement is the rapidity and accuracy with
which holes can be made in laths, solid pieces of wood or other material.
Reference is to be had to the accompanying drawings forming part of this
specification, wherein
Figure 1 is a side view of machine,
Figure 2 is an end view, and
Figure 3 is a plan.
The same letters of reference indicate like parts in all the figures.
In Figure 1, a is a tablestand which supports the sliding tray; b is a metal
frame in which the sliding rail plate works; c is a pressure screw which operates
the sliding rail plate; d is a screw to regulate the distance to which the sliding
rail plate is to be brought down; e is a fly-wheel.
In Figure 2, fis a presser foot which prevents the displacement of the laths
when the awls are withdrawn; g is a detachable part of the sliding rail plate into
which the awls are placed; h is a sliding rail plate to which the plate gis
attached; i is a series of awls; j is a sliding tray which holds the laths to be
pierced; is a series of grooves or ribs in sliding tray; is a shaft.
In Figure 3, m is a transverse pressure screw.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;
The herein described mode of piercing holes in wood or other material by means
of a series of steel awls attached to a sliding rail plate working at an angle to a
sliding tray, substantially as specified.
