FRANKLIN BAYLIES, of the City, County, and State of New York, United States
of America. "A NEW COMBINATION OF MACHINERY FOR CUTTING OUT AND
SHAPING BLANKS FOR RUBBER SHOES OR OTHER ARTICLES FROM A CONTINUOUS
WEB OR SHEET OF MATERIAL."
The object of my Invention is to cut out shoe blanks or such like articles from
the web or sheet of the material from which they are to be formed to save the
cost of cutting them by hand after the web has been run out of the machine.
In a previous Invention, a Patent for which was granted to Slade, Ford, and
Baylies by the United States Government, and also by the English Government, the
blanks are cut into shapes by mechanism while the web or sheet is carried forward
on a roll, the cutter being moved parallel with the axis of the roll shaft which
carries the web, the cutter being moved and turned to suit the angle to be cut by
means of a revolving cam.
In my present Invention the cutter is moved by mechanism both parallel with
the carrying and supporting roll and also in the direction of the length of the sheet
or web either in the direction of the line of its movement or against the said line
of movement as the shape of the blank may require, while at the same time the
cutter is turned to the proper angle to conform to the line of the cut as the shape
is being formed.
Thus any shape of blank may be made by my machine, since the

page_text: cutter may move forward faster than the sheet or slower than the sheet or web to
shape the inner or outer lines of the blank, whatever that shape may be; I have
therefore provided mechanism for cutting both the exterior lines and the interior
lines of a rubber shoe blank so perfectly that a shoe may be formed without any
hand cutting after the blank has been discharged from the machine.
My Invention consists in certain combinations of mechanism, which combinations
are specifically set forth at the end of this schedule.
In order that persons skilled in the art may make, and understand, and use my
Invention, I will proceed to describe the manner in which I have embodied it by
reference to the Drawings, in which Figure 1 shows a front view of the machine;
Figure 2 shows a vertical rear view of the same; Figure 3 shows a top view of the
same; Figures and 5 represent end views; Figure 6 shows an end view of the
parts as they appear with one side of the frame removed, and also parts of
the mechanism in section; Figure 7 is a section of the cutter spindle and slide;
Figure 8 is an end view of the same, and Figure 9 is a front view of cutter slide
and its connections, the cam for giving the horizontal motion to the cutter slide and
levers, also the carrying and supporting roll (E¹). The main or driving shaft A is
mounted in bearings b, b, on the end frames B, B¹, and is to be continuously revolved
in the direction of the arrows, Figure 4 and Figure 5; it is provided with two
discs C, C', one keyed on each end overhanging the bearings b, b; gear teeth are
raised on each disc, extending over a little more than one third, more or less, of their
whole circumference.
On one end of the said main shaft, and between the gear disc C and the end
frame B, is another gear keyed firinly to the shaft A, which communicates motion
continuously to gear D", keyed to a shaft D above and parallel with shaft A, also
having bearings in the end frames B, B'. The shaft D is provided with a roll D¹
keyed to it near the end frame B and between the latter and B¹. The roll D' is
either a callendar roll or a printing roll, as may be desired, and carries above its
upper surface the web or sheet to be acted on by the cutters.
The gear D¹¹ communicates continuous motion to gear E¹¹, keyed on the end of
the shaft E above and parallel with shaft A, and also hung in bearings on the end
frames B, B', on the shaft E; between the end frames B, B', is a roll E¹ directly over
the roll D' on the shaft D; the roll E' is that over which the web or sheet is carried,
against which the cutter acts, and on which the shape is formed as the web is moved
forward continuously on its circumference.
On this same shaft E, and near the end frame B¹, is a cam roll F, not keyed to
the shaft, but arranged to revolve on it at times, and at times to remain at rest
while the shaft continues to revolve; when the cam roll F is revolved it is done by
means of a gear f attached to it between it and the end frame B', the gear f being
actuated periodically by a gear g on the short shaft G, having a bearing on end
frame B under shaft E, which short shaft G is in turn operated by a gear h on its
outer end, meshing into the teeth of the disc C' when they engage with the gear h
during part of the revolution of the disc C³. Thus it will be noticed that the cam
roll F revolves on the shaft E as a centre or bearing, but its motion depends on the
disc C', and not on the motion of E.
Shaft E carries a rectangular frane H mounted in bearings i, i, on its two outer
ends beyond the end frames B, B¹. The said frame H hung on the shaft E as a
centre lies substantially in a horizontal direction, and receives a vibration around
the shaft E at the proper times by means of a connecting link k¹, a lever l' pivoted
to the end frame B' at m¹ and a pin n¹ running in a cam groove o¹ to be described
hereafter.
The frame H is provided with a concave plate I attached to the inside of its
front bar H, and in the face of said plate is cut a groove p of the proper shape to
turn and present the cutter to the web and roll E¹ at the proper angle, that is, at
the angle of the lines of the blank at all the parts of its configuration, the latter

page_text: depending on the shape of the cams and the motion of the web, and not on the
shape of the groove in the concave plate I.
When the concave plate I is moved upwards by means of the cam groove o' and
lever its motion is the same as it would be if it were keyed to the shaft E during
that period of time, so that the rear end of the cutter spindle which moves in the
groove p and the cutter on the surface of the roll E move in the same manner as
they would if the surface of the roll and concave plate were without motion, the
other cams giving the cutter the required cutting motions.
On the shaft E is also another horizontal rectangular frame K. mounted in bearing
on the shaft E in the same manner as the frame H outside of the end frames B, B₁;
this frame K is smaller than frame H, and vibrates within the enclosure of the other
by means of a connecting link k, a lever l pivoted to the end frame B at m, and a
pin n running in a cam groove o, to be described hereafter.
The frame K receives all its motions from the groove o, and that motion is around
the shaft E as a centre; it carries the cutter up and down on the surface of E,
sometimes faster than the speed of the surface of E, and in the same direction as
said surface, at times in a direction opposite to the motion of the surface of E and
at other times having no motion, when the cutter is permitted to cut the web in lines
parallel with the line of motion of the surface of E by the forward movement of
E alone.
The front side of the frame K near the concave plate I is provided with guiding
ways to sustain and guide in a direction parallel with the axis of E the cutter
slide q; to the cutter slide q is pivoted a link r, and said link is attached by a
similar joint to the upper end of a vibrating lever 8 on a shaft having a bearing in
a plate t fixed to the said guiding ways, on which shaft the lever vibrates.
The lever s is moved, and the cutter slide with it, by means of another short
lever attached to the short shaft v, carrying a pin w running in the groove x in the
surface of the cam F.
The cam F gives motion to the levers and slide q and the cutter in the direction
parallel with the axis of the shaft E, and said cam gives no other motion.
Parallel with shaft A in the saine horizontal plane is a shaft L, having bearings
On
in the end frames B, B', and extending beyond the end frames on each end.
one end is keyed a gear y, which at times meshes into the teeth on the disc C, at
On the
which times the disc gives the gear y and shaft L exactly one revolution.
other end of the shaft L outside of the end frame B' is attached a cam disc z, in
the outer face of which is a groove o before referred to this cam is so shaped
that when the shaft makes one revolution the rectangular frame H makes one
vibration up and down, the concave plate moving up with the frame at the same
speed that it would if it were attached to the shaft E, and down again at the same
time and with about the same proportionate speed as the concave plate I. There is
a notch in the circumference of the disc ¹ into which a lever catch a enters under
the force of a spring, and holds the disc in a fixed position until the said catch is
raised by means of a cam a¹ on shaft A located just outside of end frame B'
between the latter and disc C¹, the catch being pivoted to B¹, and being provided
with a lever the end of which is raised by the cam a¹ to hold the catch out of its
notch when the shaft L is in motion.
On the shaft L between the end frames B, B', is another cam disc z, in the face of

frame K up and down by means of the levers before described while the shaft L is
making one revolution.
On shaft A is another face cam a² inside the frame B', and another lever catch
pivoted to frame B¹ to prevent cam D from moving; the end of this catch enters a
notch in the hub of the gear on the short shaft G when the gears and the cam F
are to be put in motion by the teeth on disc C. The cam a raises the catch and
holds it away until cam F has made one revolution.

page_text: OPERATION.
The shaft A having been put in motion by power, the rolls D₁ and E¹ are caused
to revolve continuously together, the roll E turning in the same direction as the
shaft A. The web or sheet is carried between the top of D¹ and the bottom of E¹,
and over the top of E', covering its surface. When the cutter W is at the extreme
end of its vibration towards the frame B¹, and stands vertically, the sheet is cut in
a line parallel with the line of motion of the sheet or web. When the teeth on the
disc C engage with the teeth of the gear on the end of the shaft. L, and the teeth
of the disc C' engage with the teeth of the gear g on the short shaft G, the catches
having been raised to permit motion of the gears, the frames H and K and the
cutter W being at their lowest position, the cams F, and z, and s¹ begin to revolve,
and the cutter W begins to be moved by the combined action of F and over the
surface of E¹, and cuts the web of rubber or other material in a shape corresponding
to their combined motions (in this case the inner lines of a rubber shoe blank),
while the cam 21, through the levers, causes the concave plate I to follow the motion
of E', the groove (p) in the concave plate turns the cutter to the proper angle to
make a clean cut in the rubber. For this purpose a shoc is fitted in said groove
and attached to the end of the cutter spindle, which following the said groove turns
the cutter spindle and cutter according to the requirements. The cutter W is con-
nected to the cutter spindle, and may or may not revolve on its axis, but I prefer to
make it a revolving cutter, with a spring to press the shank on which it is pivoted
towards the web and surface of E¹, as is represented in Figures 7 and 8, and
substantially as is shown and described in the Patent issued to myself, Slade, and
Ford above referred to.
While the cutter is being carried across the sheet it may advance in the line of
the direction of the movement of the sheet faster than the said movement, and to
shape curves and reverse curves in the web as desired, the cam F, and 2, and the
groove in the concave plate being shaped accordingly. It is particularly to be
noticed that the cam F gives the cutter its entire motion parallel with the axis of
E' and the cams, the entire motion in lines parallel with the movement of E' on
its axis, the cam groove in the concave plate I serving only to turn the cutter to
the proper cutting angle, and this it is enabled to accomplish by following the
surface of E during its upward stroke. Straight lines parallel with the movement
of the web may be made by stopping the action of the cam F on the cutter slide
and holding the cutter in a vertical position in the groove of the concave plate I.
I propose to combine in one machine cutters to shape the blank, both on outside and
on inside lines, by the addition of more cutters and cams to do the required work.
It is obvious that a great variety of changes may be made without effecting the
substance of my Invention.
•
Having now fully described my Invention and my way of constructing it, what
I claim and desire to secure by Letters Patent is,-
First. The combination, substantially as hereinbefore set forth, of a supporting
and carrying roll or other surface for supporting and carrying forward the web or
sheet to be cut, and the cams and connections adapted to move the cutter in the
direction of the movement of the web to be cut, and also at right angles to that
direction, substantially as before described.
Second. The combination substantially as herein before set forth of the supporting
and carrying roll with the cutter slide, cams, and connections, adapted to move the
cutter over the surface of said rolls both parallel with its axis and at right angles
thereto, for the purpose of cutting any desired shape in the sheet or web of material
while under motion.
Third. The combination, substantially as hereinbefore set forth, of the supporting
and carrying roll, the cutter spindle and slide, and one or more cams, with suitable

page_text: connections, and the swinging frame, provided with a guiding plate for turning the
cutter to the angle of the shape to be cut, substantially as set forth.
Fourth. The combination, substantially as herein before set forth, of the supporting
roll, the swinging frame provided with a guiding plate, the swinging frame provided
with the cutter slide ways and cutter slide, and the cams and connections arranged
to operate substantially in the manner and for the purposes set forth.
In witness whereof, I, the said Franklin Baylies, have hereunto set my
hand and seal, this Sixteenth day of April, in the year of our Lord
One thousand eight hundred and seventy nine.
