We, TOM BIRKETT BARKER of Scholefield Street, Birmingham, in the County of
Warwick, Manufacturer, and JAMES ALFRED EWINS of Scholefield Street, Bir-
mingham, aforesaid, Machinist, do hereby declare the nature of said invention for
"IMPROVEMENTS IN PRESSES OR MACHINES FOR THE CUTTING OUT OR IMPRESSING
OF LEATHER, SHEET METAL, PAPER, CARDBOARD AND SUCH LIKE SUBSTANCES, FOR
VARIOUS PURPOSES to be as follows:-
">
Our invention has for its object to construct presses or machines for the cutting
out, impressing, shaping or raising of leather, sheet metal and other analagous
substances for various purposes, in a simple and more efficient manner than
hereto-fore; and also in rendering such machines noiseless in their action or
during their working, by constructing and arranging the parts of the said presses
or machines as hereinafter described; and further the machines so constructed,
are arranged in such a manner, that any breadth or length of material to be
operated upon, can be fed between the cutters or acting parts, without the necessity
of subdividing the pieces into strips preliminary to its being operated upon; and
our said invention consists first in employing worm or tangent wheel gearing for
driving and operating the machine, which is thereby rendered silent or noiseless
during the working thereof;- and secondly, in an improved means in the form of a
cam, for giving the necessary reciprocating or rising and falling motion to the table
upon which the material to be operated upon is placed. This last named expedient
works within a frame, the direction of motion of which is determined by guides.
Thirdly, a wedge or graduated incline arrangement for determining the amount of
stroke or the throw that shall be given to the reciprocating frame and table carried
by it; and lastly, the general construction or arrangement of the machine.
We will describe our invention as applied to a press or machine for the cutting
out of the soles or other parts of boots and shoes.
The frame of the machine consists of a vertical rectangular winged shaped
casting, having a broadened or widened out base with suitable supporting flanges;
the body of the casting is hollowed out, in order to reduce its weight, while at the

consists of an over-hanging flange like plate which constitutes the fixed surface
or abutment against which the material to be cut out or operated upon is brought;
and mounted in front of the frame or casting, are suitable bearing brackets or
blocks which carry a horizontal shaft having a pulley at its near side, and a fly-
wheel at the other; and at or about the middle of this shaft, which comes in front
of the framing of the press, is an endless screw or worm, which gears with a
tangent or worm wheel above it. This worm or tangent wheel is mounted upon
an axis at right angles to the before named shaft, and it also carries a rising and
falling expedient, in the form of a cam, for giving the necessary reciprocation to a
frame, carrying the table or bed.
The worm wheel axis is carried by a hanging bracket attached to the frame
of the press.
The sliding frame carrying the bed or table consists of a frame capable of
reciprocating to and fro, and working within suitable guides for determining its
movement; and within a rectangular opening in the said frame, the cam on the
worm wheel shaft works; and situated at the upper or that part crossing the
opening of the frame, is a steel abrasion plate, and above this steel plate, is a
wedge or taper bar, working within suitable openings and adjusted in position
by a screw and hand wheel or other equivalent. This wedge or taper bar is to
regulate the distance between the cutting bed and the top or fixed head of
the press.
The motion of the machine is as follows, after the requisite adjustment has been
obtained, with regard to the cutters or impressing tools, motion being communicated
to the drum or pulley, the driving axis is rotated, and the worm wheel gearing
with the tangent wheel above it rotates the cam axis, and with it the cam, the
excentricity of which, compels the sliding frame upon which the table is mounted,
to reciprocate, and so raise and lower the table carrying the cutting out tools, and
also the bed upon which the material to be cut out is placed; thus, the acting
edge of the cam presses and works against a steel bearing plate in the top of the
rectangular opening of the frame, and the position of this bearing plate is deter-
mined by the wedge or taper bar which is drawn across the top of the plate in
adjustment; so that the rotary motion of the cam shaft and cam through the
worm wheel, gives a rising and falling motion to the bed and cutting out tools,
thereby cutting out materials into any shape or form, fed between the said bed and
the fixed top of the press.
'
Instead of employing a single acting cam, one with two or more throws may be
employed with like effect, to produce the number of reciprocation at any given
time.

WE, TOM BIRKETT BARKER of Scholefield Street Birmingham, in the County
of Warwick, Manufacturer and JAMES ALFRED EWINS of Scholefield Street Bir-
mingham aforesaid, Machinist, do hereby declare the nature of said invention for
"IMPROVEMENTS IN PRESSES OR MACHINES FOR THE CUTTING OUT OR IMPRESSING
OF LEATHER, SHEET METAL, PAPER, CARDBOARD AND SUCH LIKE SUBSTANCES, FOR
VARIOUS PURPOSES," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :---
:
Our invention has for its object to construct presses or machines for the cutting
out, impressing, shaping or raising of leather, sheet metal and other analagous
substances for various purposes, in a simple and more efficient manner than
heretofore; and also in rendering such machines noiseless in their action or
during their working, by constructing and arranging the parts of the said presses
or machines as hereinafter described; and further, the machines so constructed,
are arranged in such a manner, that any breadth or length of material to be
operated upon, can be fed between the cutters or acting parts, without the necessity
of sub-dividing the pieces into strips preliminary to its being operated upon;
and our said invention consists first, in employing worm or tangent wheel gearing
for driving and operating the machine, which is thereby rendered silent or
noiseless during the working thereof; and secondly, in an improved means in
the form of a cam, for giving the necessary reciprocating or rising and falling
motion to the table upon which the material to be operated upon is placed. This
last named expedient works within a frame, the direction of motion of which is
determined by guides. Thirdly, a wedge or graduated incline arrangement for
determining the amount of stroke or the throw that shall be given to the recipro-
cating frame and table carried by it; and lastly, the general construction or
arrangement of the machine.
We will describe our invention as applied to a press or machine for the cutting
out of the soles or other parts of boots and shoes.
The frame of the machine consists of a vertical rectangular wing shaped casting,
having a broadened or widened out base with suitable supporting flanges; the
body of the casting is hollowed out, in order to reduce its weight, while at the
same time retaining the stability required. The head or crown of the casting
consists of an overhanging flange like plate which constitutes the fixed surface
or abutment against which the material to be cut out or operated upon is brought;
and mounted in front of the frame or casting, are suitable bearing brackets or
blocks which carry a horizontal shaft having a pulley at its near side, and a fly
wheel at the other; and at or about the middle of this shaft, which comes in front
of the framing of the press, is an endless screw or worm, which gears with a
tangent or worm wheel above it. This worm or tangent wheel is mounted upon.
an axis pt right angles to the before named shaft, and it also carries a rising and

page_text: falling expedient, in the form of a cam, for giving the necessary reciprocation to
a frame, carrying the table or bed.
The worm wheel axis is carried by a hanging bracket attached to the frame
of the press.
The sliding frame carrying the bed or table consists of a frame capable of
reciprocating to and fro, and working within suitable guides for determining its
movement; and within a rectangular opening in the said frame, the cam on the
worm wheel shaft works; and situated at the upper or that part crossing the
opening of the frame, is a steel abrasion plate, and above this steel plate, is a
wedge or taper bar, working within suitable openings and adjusted in position
by a screw and hand wheel or other equivalent. This wedge or taper bar is to
regulate the distance between the cutting bed and the top or fixed head of
the press.
The motion of the machine is as follows, after the requisite adjustment has been
obtained, with regard to the cutters or impressing tools, motion being communicated
to the drum or pulley, the driving axis is rotated, and the worm wheel gearing
with the tangent wheel above it, rotates the cam axis, and with it the cam, the
excentricity of which, compels the sliding frame upon which the table'is mounted,
to reciprocate, and so raise and lower the table carrying the cutting out tools and
also the bed upon which the material to be cut out is placed; thus, the acting
edge of the cam presses and works against a steel bearing plate in the top of the
rectangular opening of the frame, and the position of this bearing plate is deter-
mined by the wedge or taper bar which is drawn across the top of the plate in
adjustment; so that the rotary motion of the cam shaft and cam through the
worm wheel, gives a rising and falling motion to the bed and cutting out tools,
thereby cutting out materials into any shape or form, fed between the said bed
and the fixed top of the press.
Instead of employing a single acting cam, one with two or more throws may
be employed with like effect, to produce the number of reciprocations at any
given time.
We will now proceed to describe with reference to the accompanying Drawings,
the manner in which the same is to be performed.
Figure 1 is a side elevation, and figure 2 is a part vertical section of a press or
machine for the cutting out or impressing of leather, sheet metal, paper, cardboard,
and other like substances, constructed according to our invention. Figure 3 is
an end elevation of the cam arrangement, with the abrasion plate partly in
section.
The same letters of reference indicate corresponding parts in the several figures
of the Drawings.
a is the framing of the machine, consisting of a rectangular wing shaped casting,
having a broadened and widened out base, with supporting flanges upon which the
'said casting rests. The head or crown of the casting is marked a², and consists of
an overhanging flange like plate with a strengthening rib; the transverse section
of which represents the letter T, in which the cross top constitutes the fixed
surface or abutment, against which the operating tools are brought and pressed.
b bare brackets or bearing blocks, which carry a horizontal shaft c having upon
its near side a pulley d and a fly wheel e; and at or about the middle of the said
shaft, and in front of the framing of the press, an endless screw or worm fis
situated; which endless screw gears with a screw or tangent wheel g, situated
above it. This worm or tangent wheel is mounted upon an axis or shaft h at right
angles to the before named shaft c which carries the worm or screw; and mounted
upon the shaft h is a cam i or other rising and falling expedient, for giving the
necessary reciprocation to the frame carrying the table or bed j.
The worm wheel axis is carried by a bracket & best seen in tigure 1.
The said table is provided with a shaft j' depending from its underside; and
working within the eyes of guide brackets for determining its vertical recipro-
cation; and situated at the upper or crossing part of the opening of the frame is

page_text: a bearing or abrasion plate m for the cam to work against, on the reciprocation
of the bed; above this plate, a wedge or taper bar n crosses the machine, which
taper bar n works within suitable guides, and is adjusted laterally by a hand
wheel o, with its bushed middle internally wormed, which screws upon the screwed
end n2 of the taper bar n. 02 is a collar or boss on the inside face of the hand
wheel o which collar takes its abutment upon the end ³ of the frame carried by
the shaft. The taper bar n is to regulate or determine the distance between the
cutting bed and the underside of the head of the fixed frame; in other words,
to regulate the distance of reciprocation of the bed, consequent upon the throw
of the cam.
The motion of the machine is as follows, after the requisite adjustment has
been obtained with regard to the cutters or impressing tools; thus on motion
being communicated to the drum or pulley d, the driving axis c and worm f is
rotated, which latter rotates the tangent wheel g above it, and also the cam i
situated upon the same shaft h, the excentricity of which said cam compels the
sliding frame (upon which the table ; is mounted) to reciprocate, and so raise
and lower the table with the cutting out, impressing or shaping tools, and so
cutting out, impressing or shaping the material placed between the bed j, and the
underside of the cutting out or impressing tools which are pressed against the
fixed top a² of the casting a.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
First. Operating the reciprocating bed or table, or transmitting motion from
the driving pulley or axis to the cam shaft, by means of worm and tangent
wheel gearing, arranged and working in the manner, substantially as described
and illustrated.
Secondly. Adjusting or regulating the throw of the reciprocating table or bed,
whereby the cut or impress of the operating tools is determined. The said adjust-
ment is effected by a taper bar, moved transversely within a recessed part of the
reciprocating frame, the position of the wedge or taper bar being determined or
regulated by a hand wheel, or other similar mechanical equivalent, taking upon
a portion of the screwed end of the bar, with the bossed inside edge of the wheel,
resting against the end of the frame, substantially as described and illustrated.
Thirdly. The general construction and arrangement of the parts of presses or
machines for the cutting out or impressing of leather, sheet metal, paper, cardboard
and such like substances, consisting essentially of a reciprocating bed, operated
by a cam worked from worm and worm wheel gearing, substantially as described
and illustrated.
Fourthly. The construction and arrangement of the casting constituting the
fixed framing, substantially as described and illustrated.
