JAMES MARTIN PRICE of No. 1719 N. 18th Street Philadelphia Pennsylvania
United States of America, Inventor, 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:-
My invention relates to wheels for transmitting motion which have for their
object to transmit alternate motions and regular or irregular alternations of speed.
For this purpose my said invention consists of the combination of parts hereinafter
set forth.
In the accompanying drawing
Figure 1 represents an end view of a pair of driving wheels, either of which may
impart motionito the other.
Figure 2 represents an end view of a modification of the said wheels.
Figure 3 represents another modification thereof.
Figure 4 represents end views of shaping rolls adapted to be used with the.driving
wheels.
Figure 5 represents a vertical sectional view of the combined shaping rolls and
driving wheels.
Similar letters of reference indicate corresponding parts in the several figures.
A designates a pair of driving wheels for a rolling mill or other device, said
wheels having as shown in Figure 1, two series of cogs or teeth, each of the said
series being on a different but concentric circumference. Between each of the
said projecting cogs B and its adjacent hollow cog C are the shoulders D, rising
like a series of steps, and adapted to sustain the forward movement by impulsion
at each, while subdividing the work and annulling or minimizing the "shock"
otherwise .connected with the rapid transference of power and action from the cog C
to a cog B, and in immediate succession from B to the following.cog C.
In Figure 2it, will be observed that hollow or female cogs E are placed upon
the larger, circumference or at the centres of the greatest projections of the wheel,
wliile F the associate and ordinary cogs of projecting contour are.seated upon the
minor circumference, or centrally to the greatest depression in the periphery of the
driving wheels.
In this form of driving wheel, curved shoulders G are substituted for the angular
ones D.shown.in. Figure .1 .the said curved shoulders having the same function as
the said angular ones viz... to carry the transfer of motion easily from the cogs E
to the cogs F without shock, hesitation or interruption.
"It, will be understood that any number of projections with cogs on their outer
circumference with the corresponding or associate cogs on their inner circumference
may be.employed, or in other words, the number of transitions or alternations of
movement in a single revolution of a wheel is not limited. Figures 1 and. 2 show
constructions adapted for twelve transitions.
The shaping rolls H may be used in connection with the gearing shown in
Figure 1.said parts being in condition to receive and shape the transmitted strip.or
plate of metal which will enter between the rolls.
The modification shown in Figure 3, is of exceptional irregularity of shape, the
drivers not being duplicates and the driver K which imparts.motion to its fellow. K'
has the circumference of its periphery outside of the cavity L thereof, equal to that
of. the periphery of the wheel K outside of the projection L' thereon so that the
wheel K will so rotate the wheel K and the male cog M of the cavity, of the
wheel,K will, at all times coincide with the female cog N of the projection: L.

page_text: The projecting portion Land the side walls of the cavity L have straight sides or
shoulders as PP, respectively instead of curved or angular sides.
In using the driving wheels herein described, several shaping rolls may be placed
on the one axle, and rotated by one set of drivers, or two pairs of drivers may be
employed with one or more sets of shaping rolls between them.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
First. A pair of driving wheels each of uniform thickness and having two
series of cogs on different circumferential segments, substantially as described.
Second. A pair of driving wheels, each having two series of cogs or con-
centric circles with intermediate shoulders the said cogs being on each wheel and
the shoulders being between the inner and outer series of cogs substantially as
described.
Third. A pair of cogged wheels, of which the cogs are in a double series
with two different radii making diverse circumferences, of which the smaller in
one cogged wheel gear into the cogs of the larger circumference in the other,
the two wheels being of the same diameters across their greatest width and as well
across their narrowest dimension substantially as described.
Fourth. A pair of associate cogged wheels of the same dimensions, and two
radii each with regular symmetrical projections geared to regular symmetrical
depressions, each to its converse substantially as described.
Fifth. A pair of associate cogged wheels in duplicate with angular shoulders
so disposed between the greatest depressions and the greatest projections in the
peripheries of these wheels, as to aid in the rapid transmission of power from
projection to depression, or from depression to projection without shock or
uncertainty substantially as described.
Sixth. A pair of driving wheels in duplicate with two diverse radii, for the
bases and lips of their respective cogs and intervening shoulders to aid in the
forward alternate movement substantially as described.
Seventh. A pair of duplicate driving wheels with cogs in two series, of
unequal distance from the centres, but alike for each wheel, and intervening
shoulders, straight, angular or curved, between the two series, aiding in the
alternations of speed and motion produced, substantially as described.
Eighth. A pair of driving wheels of diverse diameter for the similar arcs, one
with a cavity on its circumference, the other with a boss or projection from its
circumference, to enter and move freely within the cavity, with appropriate
gearing associating these, the pair to act in driving machinery substantially as
described.
Ninth. A pair of driving wheels curved in their entire periphery, but with
alternate projections and depressions, so geared together that cogs upon or within
their projections and depressions interlock with the cogs in the associate wheel, the
curved side or shoulders precluding shock in the constant change of radius, while
acting in that transfer substantially as described.
Tenth. A pair of driving wheels of duplicate shape, and each with two radial
distances alternately placed for its gearing, and angular, curved or straight
shoulders so adjusted as to contribute to the movement while precluding shock, in
combination with shaping rolls between which strips or plates of metal are passed
to shape them into a series of waves or a series of truncated pyramids etc. substan-
stantially as described.
Eleventh. A pair of duplicate driving wheels with a series of cogs at one radial
distance from their centre, while another series occurs at different radial distance,
with shoulders straight, curved or angular, between the two series, to assist the
forward movement of the wheels, and the transfer of action from series to series
substantially as described.
Twelfth. Two pairs of duplicate driving wheels of irregular but symmetrical

page_text: periphery, arranging the cogs for each pair in two series of unequal radial distance,
with shoulders between them, contributing to their revolution, in combination with
concentric rolls or other machinery to be driven by them, either singly or in series
substantially as described.
Thirteenth. A pair of driving wheels of equal diameter each having two series
of teeth on concentric circles with intermediate shoulders forming steps substantially
as described.
Fourteenth. A pair of driving wheels of equal diameter, each having a series of
teeth on arcs of concentric circles with intermediate shoulders, the teeth of one
series being male and the teeth of the other series being female said parts being
combined substantially as described.
Fifteenth. A pair of driving wheels of equal diameter having two series of teeth
on arcs of concentric circles, the teeth of one series being male and the teeth of the
other series being female and connecting shoulders between each adjacent male and
female tooth substantially as described.
Sixteenth. A pair of duplicate driving wheels each having teeth on arcs of con-
centric circles, the teeth of the inner circle of each wheel being adapted to mesh
with the teeth of the outer circle of the other wheel substantially as and for the
purpose described.
Seventeenth. A pair of duplicate driving wheels each having teeth on arcs of
different concentric circles, the teeth of the inner circle of each wheel meshing with
the teeth of the outer circle of the other wheel, and shoulders on each wheel between
and connecting said inner and outer arcs, said parts being combined substantially as
described.
