PROVISIONAL SPECIFICATION.
Improvements in Machines for Cutting or Stamping Out Leather
and the like.
We GEORGE HENRY FAIRE of Crosslands, Upper New Walk Leicester, Shoe
Manufacturer and PEARSON & BENNION, LIMITED, of' 16, Blue Boar Lane,
Leicester, Engineers, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to machines for cutting or stamping out leather, cloth,
paper and the like, and consists of an improved machine or press in which the
upper bed, ram, or plunger is normally stationary, while the lower bed or table
upon which the material to be cut is placed, is horizontally movable and is
supported in such a manner that the whole of it may be easily moved under or
away from the upper bed, or it may be turned upon a pivot so that any part of its
surface may be passed under or away from the upper bed as desired.
The upper bed is connected to a revolving pulley by any suitable means with a
clutch or its equivalent interposed.
The clutch is operated by a lever and the whole mechanism is so arranged that,
when required, the upper bed rapidly descends and then rises to its normal position
where it stops..
Vertical adjustment may be provided for the upper bed or the lower będ
or both.

Improvements in Machines for Cutting or Stamping Out Leather
and the like.
We, GEORGE HENRY FAIRE Crosslands, Upper New Walk, Leicester and
PEARSON & BENNION LTD., Engineers, of 16 Blue Boar Lane Leicester, 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:-
Our invention relates to machines for cutting or stamping out leather, cloth,
paper and the like, and consists of an improved machine or press in which the
upper bed is normally stationary, but is provided with means for causing it to
descend rapidly and then rise to its former position, while the lower bed or table
(upon which the material to be cut is placed) is horizoutally movable and 'is
supported in such a manner that the whole of it may, when each cut is made, be
easily moved under or away from the upper bed, or it may be turned horizontally

In the accompanying drawings:-
Figs. 1 and 2 are respectively front and end elevations showing one form of press
containing our invention.
Figs. 3 & 4 are respectively front & end elevations of another form of press
containing our invention.
In the press shewn by Figs. 1 and 2, an auxiliary lower bed A is provided, upon
which the lower bed proper B (covered with wood etc. C) is moved horizontally
under or away from the upper bed F, on slides A', by the handwheel D, shaft D',
pinions D and racks B².
The lower bed A is adjusted vertically, by means of the hand wheels E, screws E¹
and nuts E.
Rollers may be employed to reduce friction between the beds A & B.
In the press shewn by Figs. 3 and 4, the lower bed B, which is preferably
circular in plan, and made of wood or other soft material, is mounted upon a
vertical pivot J supported by a spring K. and held at the correct height by a
collar L. It is capable of being easily revolved horizontally and is normally clear
of the framework M, but when a cut is being made the spring K yields and allows
the bed B to rest upon the framework M.
The upper bed F is guided by slides N and is vertically adjusted by the hand-
wheel E, screw E' and nut E³.
In each of the presses illustrated in the drawings the upper bed F is normally
stationary but when a cut is required to be made, the operator, by depressing the
foot-board G, causes the upper bed to rapidly descend and then rise to its former
position.
In the press shewn by Figs. 1 and 2, the mechanism connecting the foot-board G,
belt-driven pulley H, and upper bed F, is similar to that employed in the well
known "Revolution " presses now being extensively used in shoe factories, and its
action may be described as follows: When the foot-board G is depressed, the
brake shewn at the left-hand of Fig. 1 is released, and the pulley H is moved
laterally, by means of a series of levers &c., until it engages with a friction cone
which is keyed to a driving shaft carrying two eccentrics, causing the latter to
revolve and impart motion through links, crossheads, and slide rods to the upper
bed F.
During the descent of the upper bed the operator removes his foot from the foot
board, which is held down (by a cam fixed to one of the slide rods acting upon a
roller attached to the clutch operating mechanism,) until the upper bed has
descended and nearly completed its ascent, when a spring raises the foot-board,
thus releasing the pulley H from the friction cone, and applying the brake which
stops the rotation of the eccentrics when the upper bed has reached its highest
position.
The mechanism for actuating the upper bed of the press shewn in Figs. 3 and 4
is a simple modification of that described, the chief differences being that only one
eccentric is employed, and the cam for maintaining the engagement of the pulley
with the friction cone is carried by an elongation of the joint pin at the lower end
of the screw E'.
We have only described and illustrated two applications of our invention, but we
wish it to be understood that it may be adapted to other forms of presses used for
similar purposes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
.claim is :-
In machines for cutting or stamping out leather &c., having an upper bed
normally stationary, but provided with means for causing it to descend rapidly,
and then rise to its former position, the employment of a lower bed or table

desired.
