PROVISIONAL SPECIFICATION.
A New or Improved Device for Use in connection with the Treadles
of Sewing Machines, Fret-saws, and other Similarly Aotuated.
Machines.
I EDWIN ALFRED GUY, of 101, Neville Road, Stoke Newington, London, in
the County of Middlesex, Salesman, do hereby declare the nature of this invention
to be as follows:-
My invention relates to a new and improved device for use in connection with
the treadles of sewing machines, fret-saws an I the like; and it is intended to do
away with the heel pressure which at present is a source of fatigue and disense
amongst the operators of machines of the type in question.
In order that my invention may be readily understood I shall hereinafter des ribo
it with reference to one contemplated form thereof, the said contemplated form
being herein specified merely as a type or example of what is embraced within the
Scope of my invention.
In constructing the said contemplated form of my invention, I attach a look to
the under side of the table or plate, which bears the sewing machine proper or
fret-saw or other machine. This book may be so attached, either by screwing into
the table or plate direct or by providing it with a base plate by means of which it
can be screwed or nailed to the said table or plate. From the said hook depends
a chain to the lower extremity of which is attached in any convenient manner a
hollow cylinder or tube. Within the said cylinder or tube is a rod the upper end
of which hears a knob, disc, or extension piece. This rod lies in the geometric
axis of the cylinder, or tube, its lower end passing therethrough and being attached
to a swivel, which latter is attached, by screwing or otherwise, to the treadle or
foot plate of the machine. Within the said cylinder or tube, and surrounding the
said rod, is a helical spring, the upper end of which abuts against the aforesaid
knob, whilst its lower end abuts against the bottom of the cylinder.
The action is as follows:-
When the treadle is depressed by the fore part of the fout the helical spring is
compressed, a part of the rod being pulled from out of the cylinder or tube. On
the pressure of the foot being withdrawn the spring expands again and the treadle
is raised without the necessity of exerting heel pressure as will be readily
understood.
The object of the chain is to render the device adjustable so that one or
more links may be taken up or let out in order to shorten or lengthen the
device.
1 desire it to be understood that I do not limit myself to the details hereinbefore
specified as these may be varied to an indefinite extent.

Machines.
I, EDWIN ALFRED GUY, of 101, Neville Road, Stoke Newington, Loudon,.
in the County of Middlesex, Salesman, 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 aud by the following statement :-
My invention relates to a new, and improved device for use in connection
with the treadles of sewing machines, fret-saws and the like; and it is intended
to do away with the heel pressure which at present is a source of fatigue and
disease amongst the operators of machines of the type in question.
In order that my invention may be readily understood I havo appended hereto
a sheet of drawings illustrating one form of my invention, the said form being that
.which I have found to give good results in practice. In the said drawings
Fig. 1 is a diagrammatic view of my invention as applied to a sewing machine, and
Fig. 2 is a view of my invention as detached from the machine, in connection with
which it is designed to be used.
In carrying the said form of my invention into effect, I attach a hook 1 to
the under side of the table or plate 2, which bears the sewing machine proper, or
.fret saw or other machine.
This hook is attached by means of screws passing through the screw holes 3. 3.
in the base plate 4. From the said hook depends a chain 5, to the lower extremity
of which is attached in any convenient manner, a hollow cylinder or tube 6, closed
at both ends, but having an orifice at its lower end. Within the said cylinder or
tube is a rod 7, the upper end of which bears a knob disc or extension pioce 8.
This rod lies on the geometric axis of the cylinder or tube, its lower end passing
therethrough, and being attached by surewing or otherwise to the treadle or
foot plate 10 of the machine.
Within the said cylinder or tube and surrounding the said rod is a helical
spring 11, the upper end of which abuts against or is attached to, the aforesaid
knob, whilst its lower end abuts against the bottom of the cylinder.
The action is as follows:-
When the treadle is depressed by the fore part of the foot the helical spring
is compressed, a part of the rod being pulled from out of the cylinder or tube.
On the pressure of the fout being withdrawn the spring expands again and the
treadle is raised without the necessity of exerting heel pressure, as will be readily
understood.
The object of the chain is to render the device adjustable so that one or
more links may be taken up or let out in order to shorten or lengthen the
device.
I desire it to be understood that 1 do not limit myself to the details hereinbefore
specified as these may be varied to an indefinite extent without departing from the
spirit of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what mannor the same is to be performed, I declare that what I
claim is :-
1. The new or improved device for use in conuection with the treadlee of
sewing machines, fret saws and other similarly actuated machines, substantially
as set forth.

page_text: 2. The arrangement and combination of parts substantially as set forth with.
reference to Figure 2.
