! Improvements in Treadle Presses, applicable for Olicking, Heeling
and Analogous Purpose8.
I, JAMES ALFRED KEAY, of the Union Works, Belgrave Road, Leicester, do
hereby declare the nature of this invention to be as follows:-
1
This invention relates to improvements in treadle presses applicable for click-
ing heeling and analogous purposes. The object of the invention is to construct
a treadle press specially adupted for clicking purposes and capable of perform-
ing the operation of such presses without the aid of any power other than that
imparted by the operator, and the improvements are also applicable to heeling
und analogous machines, as before stated.
To carry out the invention I construct a frame with a vertical bead standing
out therefrom and immediately over a table formed with or attached to the said
frame, and an arm may project rearward of the latter.
Near the bottom of the frame suitable provision is made for a shaft upm which
is fulcrumed a treadle, the front part of which projects forward of the frame.
The back or rear end of the said treadle projects beyond the fulcrum and has
a hole preferably rectangular passing partly or wholly therethrough. The said
hole is formed approximately at an angle of 60 degrees with the upper face of
the treadle.
A bar the same shape as the hole, has its bottom end slid therein, its upper
end projecting a suitable distance. A weight is placed on the top end of the
said har and held in the required position by set pins.
The said weight may be so shaped that as the treadle is depressed and the bar
brought to its approximately vertical position, the two forward sides of the
weight may partially enclose the sides of the frame, while a rubber or other
suitable buffer fixed to the weight will receive the impact between the latter and
the back of the frame.
The power is conveyed from the treadle by connecting to the latter at a point
preferably forward of and below the fulcrum thereof, a rod passing upward through
the frame and connected centrally with a beam, the rear end of the latter being
connected by a link to the rear arm of the frame before mentioned. The forward
end of the beam is pivotted to a plunger which passes through the vertical head
of the frame. The said plunger is adapted to receive therein a screw, at the
bottom of which is carried the block for pressing upon the knife.
It will be readily understood that when the operator's foot depresses the treadle,
the position of the weight on the bar adds great additional force for the cutting
operation, while when the operator removes his foot, the weight will bring the
treadle to its upper or normal position.
A spring may be provided to assist the weight in raising the treadle and a
buffer stop to take any impact.
Various modifications may be made in the positions of the connections between
the treadle and the beam and the connection of the latter to the frame without
Heparting from the nature and object of this invention.

page_text: The means herein before described for the operator to impart power to the
plunger may be utilized for compressing the lifts in building heels and also for
attaching the latter, by adding any of the well-known apparatus for effecting the
several purposes.
Improvements in Treadle Presses, applicable for Clicking, Heeling
and Analogous Purposes.
I, JAMES ALFRED KEAY, of the Union Works, Belgrave Road, Loicester,
Engineer, 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 improvements in treadle presses applicable for click-
ing, heeling and analogous purposes, the object of the invention 'being to con-
struct a treadle press adapted for clicking and other purposes and capable of
performing the functions of such presses without the aid of any power other than
ihat imparted by the operator.
The invention will be understood from the following further description, refer-
ence being had to the accompanying drawing which represcuts a perspective view
of a treadle press constructed in accordance with this invention.
The frame A has a vertical head A standing out therefrom immediately over
a projecting table As preferably integral with the frame but which may be
bolted thereto when desired. An arm A projects rearwardly from the frame A
and has pivotted on the pin B passing therethrough, a link C which in turn is
pivotted at C to a beam D. The forward end of the beam D has pivotied to
it at D the upper end of a plunger E movable vertically in the head A' of the
frame A.
The plunger E is cut internally to receive a screw adjustable in the plunger E
and on which is formed or to which may be attached in any desired way the
block, platen or buffor F for pressing upon the knife when the press is used for
clicking or other cutting operation.
The block, platen or buffer F is hereinafter called the "form" by which is
meant any device, die or other apparatus to be carried by the screw F and
necessary for adapting the press for other operations than clicking.
A treadle is fulcrummed on a shaft G the latter having its bearings iu
bosses (a) on each side of the frame A.
The said treadle is formed with a front part extending forward for the
operator's foot and with its back or rear end Ge projecting beyond the fulcrum at
nu angle approximately of 60 degrees with the upper face of the treadle. A
bar I preferably rectangular in section has its bottom end slid into a hole or
recess formed in the end to receive it, and it is held in position by a screw, (9
or other suitable means. The treadle ( is connected to the beam D by means
of a rod which at its upper end is pivotted to the said beam at J and at its
bottom end to the treadle at J. The position of the connection J2 of the rod J
on the treadle in relation to the treadle fulcrum at G is such as to attain the
most effective movement and force of the form F'.
To increase the power and rapid and effective operation of the press a weight K
is placed upon the bar H and retained in any desired position thereon by Bet
screws (not shown) or other suitable means,

page_text: The said weight is so positioned or balanced on the bar H that the forco
necessary to be exerted by the operator on the treadle is very small, the normal
position of the weight being such that it is moved forward in an approximately
horizontal line until the bar reaches a vertical position.
The action of depressing the treadle and moving the weight as before stated
imparts considerable force by means of the rod J, beam D and plunger E to the
form to accomplish the cutting or other required operation. As the depressing
of the treadle causes the bar II to assume an approximately vertical position, and
as the weight K and other parts nearly balance, the return of the said parts to
their normal position after the operator moves his foot from the treadle after
each operation, is ensured by means of a spring L which engages a hook L' fixed
in the treadle, the upper end of said spring being secured to the frame A at any
convenient point, or it may be passed over the end of a hell-crank lever M
tulerummed on a pin M¹ carried in the frame, and the vertical end of said lever
be engaged by a screw N passing through a boss A and actuated by means of a
hand wheel N fixed on said screw.
The tension of the spring L may thereby be adjusted to regulate the balance
of the treadle and weight in accordance with the position of the latter on the
bar K.
A rubber or other suitable pad O is fixed in the recess K' of the weight K
to receive the impact between the latter and the back of the frame, and a pad a¹
of similar material is fixed to the frame or to the top face of the treadle to receive
the impact between the two parts.
Modifications may be made in the positions of the connections between the
treadle and the beam and of the latter to the frame without departing from the
spirit of this invention.
The means hereinbefore described by which the operator imparts force to the
plunger may be utilized for compressing the lifts in building heels and for
attaching same and also for analogous purposes by carrying in the plunger or
on the screw any of the well-known apparatus for effecting the several purposes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A foot press comprising a treadle and mechanism connected with the treadle
to bring a form into a position of pressure, the treadle having combined there-
with a bar and an adjustable weight by which the force imparted to the treadle
by the operator is supplemented substantially as described.
2. A foot press, having, in combination, a pressure form adjustable in a plunger
a beam and link pivotted to a frame and means connecting the beam to a treadle
the latter carrying an adjustable weight by which the force imparted to the
treadle by the operator is supplemented, substantially as described.
3. A foot press, having, in combination a form adjustable in a plunger a
treadle and connecting mechanism to bring the form into a position of pressure,
means carried by the treadle to supplement the force and a spring to ensure
the return of the parts to their 'normal position, substantially as described.
4. A foot press, having, in combination, an adjustable form a treadle and con-
necting mechanism to bring the form into a position of pressure means carried
by the treadle to supplement the force, a spring to ensure the return of the
several parts to their normal position and means for adjusting the tension of the
spring substantially as described.
