Year: 1885

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake and Co, Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVED APPARATUS OR MACHINERY FOR MARKING OR
GRADING AND CUTTING OUT THE SOLES OF BOOTS OR SHOES OR FOR SIMILAR
PURPOSES" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement
-
The apparatus, for grading patterns and for other like purposes is described,
more especially, for the grading of patterns for boot and shoe soles, or in other
words, for the cutting out of boot and shoe soles in their varying sizes, either as to
width, or length, or as to both width and length, from the use of a common pattern-
block, having the proper shape, both in width and length, for a boot or shoe sole of
a size corresponding to such pattern, and for that reason, this invention is berein
shown and described, in reference to such application of it, and although it is 80
particularly illustrated and described, it is intended to apply it to the grading of all
patterns for which it may be found adapted
This machine is composed in substance, of the following elements, to wit
First A horizontal stationary former, in the present instance, of the proper
outline of a boot or shoe sole
Second A tracer, arranged to travel around and about the periphery or edge of
the said sole-former
Third A suitable knife or marker
Fourth A cutting block or table
Fifth A clamp for clamping the material to be cut, or marked upon the cutting-
block, or table
Sixth-Mechanism, constructed and arranged, First, to produce from the travel
or movement of the tracer about the periphery of the sole-former, a travel of the
cutting-knife, or marker in a corresponding outline or direction and second, to be
capable of an adjustment to secure from one and the same sole-former, the cutting
[Press 18 10/1

page_text: out, by the cutting knife, of a boot and shoe sole in any one of the varying sizes,
either as to length, or as to width, or as to both, of boot or shoe soles
Seventh, Mechanism, constructed and arranged, first, to cause the cutting knife
to cut out a boot or shoe sole, in the movement of the cutting-knife, because of its
above stated connection with the travel of the tracer about the sole former and
second, to secure a presentation of the cutting edge of the cutting knife to the
material from which a boot or shoe sole is being cut and at any and all parts of the
cutting operation in a line substantially parallel or coincident with the direction of
such cut.
This invention in substance consists
First, of a tracer, made in parts, arranged to slide upon each other and adopted
the one, to bear upon the edge of a stationary sole or other suitable former or
pattern, and the other, to travel in a stationary guideway about such pattern, in
combination with a spring, arranged, through arms connected therewith, to hold the
one moving part, to its bearing against and upon the edge of the former or pattern,
and the other moving part, to its bearing upon the guide way, and with a toothed
or ratchet-bar connected to one of said moving parts and arranged for the arm of
the spring, through which the spring acts upon said moving part, to be engaged
with its teeth, all substantially as hereinafter described

mechanism constructed and arranged for the location of and for securing said
former in position and for releasing it, all substantially as hereinafter described
Third, In combination with a stationary sole or other suitable former, or pattern,
and with a tracer, adapted to roll, or otherwise, to have a bearing against the edge
of the pattern, of an endless chain, which is connected to the said tracer, and is
arianged in relation thereto, and to the said former in a manner, to secure through
the movement of the chain, from end to end, the travel of the tracer around and
about the entire edge or periphery of the former and to permit in such travel of
the tracer, the maintenance of its said bearing upon and against the edge of the
former, at any and all parts of its length
Fourth Of the combination with the sole or other former or pattern of
mechanisin, constructed and arranged to bind and hold the former in the direction
of its thickness, at opposite points thereof, and to be released from the former
Fifth Of the combination with the sole or other former or pattern, of pins, over
and upon which to place the former, and of mechanism, constructed and arranged,
to bind and hold the former, in the direction of its thickness at opposite points
thereto, and to be released from the former

and upon which to place the former, and of mechanism constructed and arranged
to bind and hold the former, at opposite points thereof, and to release the former
Seventh Of the combination with the sole or other former or pattern, of pins,
over and upon which to place the former, and of mechanism, constructed and
arranged to bind and hold the former at opposite points thereof and also to bind and
hold the former in the duection of its thickness and to release the former
Eighth, in the combination with a stationary sole or other suitable former or
pattern, and with a tracer, adapted to roll, or otherwise, to have a bearing against
the edge of the pattern, of an endless chain, which 13 connected to the said tracer,
and is arranged in relation thereto, and to the said former in a manner, to secure
through the movement of the chain, from end to end, the travel of the tracer
around and about the entire edge or periphery of the former and to permit, in such
travel of the tracer, the maintenance of its said bearing, upon and against the edge
of the former at any and all parts of its length
Ninth, of a stationary sole or other suitable former or pattern, in combination,
First, with a trace1, which is arranged to travel horizontally, and strictly follow the
edge or periphery of said former and, in such travel, to swivel or turn in a carriage
arranged to move horizontally, forward and backward, in a straight line, over and
upon a horizontal carriage, which, together, with the tracer-calliage, is in turn,

page_text: adapted to move,-(the two as one),-forward and backward, in a straight line at
right angles to the forward and backward movement of the tracer-carriage over its
supporting carriage aforesaid, and Second, with a horizontal carriage which is
adapted and arranged, to move firstly, in one direction, forward and backward, in
a straight line, and as one with said tracer-carriage and its said supporting-carriage
in their conjoined movement as aforesaid, and to move secondly, in the o her
direction forward and backward, in a straight line, and in conjunction with the
tracer carriage in its movement over and upon its supporting carriage, and which,
for this second movement is connected, in such manner, by a pivot, to a horizontal
radius-bar in its length pivoted to the tracer-carriage and adapted to play length-
wise through a guide-block, in turn pivoted to the supporting carriage over and
upon which the tracer-carriage moves, that, for and during the whole of such
forward and backward movement of the tracer carriage, over and upon its supporting
carriage and of the similar movement of the carriage connected as aforesaid, through
the radius-bar, to it, and which move with it the relative perpendicular distance
between parallel lines drawn parallel with the travel of the trace carnage over
and upon its supporting carriage and through the axes of the pivoted connections
between said several moving carriages (to wit), the tracer carriage, its supporting-
carriage and the carriage then moving with the tracer-carriage in the same direction
over and upon the supporting-carriage, and the radius-bar, will always remain and
be the same
This construction and arrangement and operation of connection between these
several carriages (to wit, the tracer-carriage, the carriage supporting the tracer-
carriage upon and over the supporting carriage for the tracer-carriage), in addition
to other results, not necessary to now mention, gives and imparts for any and all
portions or divisions and for and during the whole length of the movement of the
tracer-carriage over and upon its supporting-carriage a movement to the carriage,
that as described moves with the tracer-carriage in its said movement over and
upon its supporting-carriage, a direct and proportionate' movement for any and
all corresponding portions or divisions and for and during the whole of the length
of its said movement in the same direction and this result is and will be the same
whatever is or may be the relative position upon the said radius-bai of the pivoted
connections between it and the said several carriages, all substantially as hereinafter
described

forward and backward in a straight line, in conjunction with the tracer carriage in
its movement over and upon its supporting carriage and in this latter movement
adapted and connected to the tracer-carriage in any suitable manner, to secure an
increase or decrease in its length, relative to the length of the similar movement
of the tracer-cariage upon its supporting carriage and Third, with a horizontal-
carriage, which is adapted to move in parallel lines with the movement of the
supporting-carriage, and over and upon and also with the carriage-connected to
and moving with the tracer carriage in its movement over and upon its supporting
canage and which in addition to said adaptation, is arranged and connected to
the carriage over and upon and with which it moves as aforesaid to receive from the
movement of the tracer-carriage with its said connected carriage, over and upon its
supporting carriage, a forward and backward movement at right angles to such

page_text: movement of the tracer-carriage and its said connected carriage and in such
movement, relative to the forward and backward movement of the supporting-
carriage for the tracer carriage, for any and all portions or divisions and for and
during the whole of the length of said movement of said supporting-carriage for
the tracer-carriage, it shall have imparted or given to it, a direct and proportionate {
movement for any and all portions and divisions and for and during the whole of
its length, all substantially as hereinafter described

wise drag upon the material, as it is so cut by, and at and about the aforesaid
operation of the suiting edge of the cutter-bar, and which together with the cutter-
bar is relatively so constructed and arranged and applied the one to the other, that,
as it so rests or drags upon the material being cut by the cutter bar and as said
cutter bar is being reciprocatingly moved, it will turn said cutter bar in such
manner, that said cutter bar will always present its cutting edge to the material
which it is to cut in a line, in substance coincident with the line along which the
material is to be cut and at and upon each and every stroke of the cutter bar,
against such material.

and all strokes of the cutter-bar and which together with the cutter-bar 18
relatively so constructed and arranged and applied the one to the other, that as it
so remains in and follows along the line of cut in the material from the cutting
operation of the cutter-bar and as said cutter bar is being reciprocatingly moved
it will turn said cutter-bar, in such manner, that, said cutter-bai will always present
its cutter-edge to the material, which it is so cut, in a line in substance, coincident
with the line along which the material is to be cut and at and upon each and every
stroke of the cutter-bar against said material

or moved toward each other and to be held in either of such position, in com-
bination with mechanism which carries one of said jaws, at opposite points, and is
constructed and arranged to be attached or connected to and detached or separated
from the clamping-jaw which it carries, at either of its parts carrying the jaw, and
such attachment and detachment, as to either of said parts, to be independent of
the similar operation of the other of said parts

well also as the further movement of the other parts of the machine
The several recited clauses of this invention herein above given cover, in
substance, the principal feature thereof, but in addition thereto this invention also

lettering where the difference in their construction and arrangement occur of
sufficient extent to require the same for an intelligible description
In the drawings A, represents a horizontal metal frame, which is supported_at
each corner, by a leg B, and makes the supporting framework of the machine, C is
the driving shaft
This diving shaft extends horizontally across the frame A, from front to rear,
turns in suitable bearings thereof and at its rear end, outside of the frame A, it is
provided with a loose driving-pulley D, which is adapted to slide upon the shaft
and has its hub a constructed with teeth and recesses b to be clutched with a
correspondingly toothed and recessed hub c, of a gear wheel E, which is made fast
to the diving shaft c
The hub a of the driving pulley D, has a peripheral groove d, which receives
the forked end e, of an angular lever F, having a fulcrum f, at the rear side of the
frame A The lever F, swings horizontally upon its fulcrum f, and it passes
through an opening at the right hand side of the bed plate or frame A, to the
outside of said frame, into a position to be conveniently grasped by hand, for
operating it to place the loose sliding pulley into and out of connection or clutch
with the driving shaft c, and gear wheel E
This clutching of the loose pulley D and driving shaft and gear wheel 19 made
against a spring g, which at one end is connected to the angular or clutching lever F,
and at the other end, to the frame A, in a suitable manner to so act and when the
clutch is made it is maintained by the interlock of a shoulder upon the upper side
of the lever with a vertical shoulder or block h, on the underside or bed plate A
(see Figures 13 and 16)
The release of the lever F, from the shouldered block h, is secured by pulling it
in a downward direction, when by the reaction of the spring g, the lever is thrown
in the proper direction, to slide the loose driving pulley D, out of clutch with the
fixed wheel E
The driving shaft C, within and near the rear side of the frame A, has a bevel
gear wheel G which meshes into a horizontal bevel gear wheel H, at the lower end
of the vertical shaft or stud 2, arranged to turn in a stationary bearing block of
the frame A.

page_text: This stud 2, projects above the bed-plate or frame A and at its upper end it has
a horizontal sprocket wheel I, partially surrounded by an endless chain K, which
passing to the right partially surrounds a similai horizontal sprocket wheel, J,
arranged to turn upon a vertical stud 1, secured at its lower end to bed-plate or
frame A
The endless chain K, under the connection above described, travels from end to
end, and about the outline of but in a horizontal plane, below the edge or
periphery k, of the sole former L, and it is connected, through a horizontal link l,
which at one end, is pivoted, to one end, of a chain link, and at the other end,
similarly is pivoted to a horizontal carriage M, which carriage, as a whole, is to be
called hereafter, the "tracer" of the machine
The tracer M, below its link connection with the endless chain K, as above
described, has two horizontal friction rolls m, m, which are placed side by side, in
a position to bear against the upright inside face n, of a raised edge o, of the bed
plate or frame A, and for the concentric flanges p, of the rolls m, to enter under
and to bear upward against the underside of the edge o, (figures 7 and 8)
This raised edge o, is a continuous one, and it is in the general outline of a boot
or shoe sole, and the tracer as it is carried around by the travel of the endless
chain K, moves and runs by its friction rolls m, in contact with the said inner
face n, of said raised edge o, and it is held, from vertical escape by the under lap
of the concentric flanges p, about sa'd rolls
The tracer M, in its travel as aforesaid rests and travels through a friction roll q,
upon and against the edge k of the sole former L
This friction roll q, swivels upon a horizontal plate r, arranged in guide_ways 8,
of the tracer, to slide toward and away from the edge of the sole former L
t, 18 a spring applied to and between the tracer slide r, and the tracer M, in a
manner to always press the said tracer slide toward the periphery of the sole former,
and thus to hold its friction roll g, in close contact therewith, and also to always
press the tracer carriage, upon which the said tracer slide noves, away from the
periphery of the sole former and thus to hold its friction rolls mm, in close contact
with the bearing face n, of the edge o against which they run
For the spring t, to act as above described, it is coiled about and at one end, it
is attached to a post u, turning upon the tracer part v, and at the other end, it has
a bearing against a pin or stud s, of the tracer part r, in a direction to force such
part toward the edge of the sole former
The turning post u, has an arm w, which engages with a ratchet or toothed barœ,
of the tracer part v, and thus the spring acts against said tracer part in an outward
direction confining said part to its bearing against the inner edge of the guide-
way o
The ratchet-bar a, at one end, 18 pivoted to the tracer part v, and it is held
engaged with the arm w, of the post u, by a bent spring y, which at one end, 18
secured to the tracer-part v
of
Thus as described the tracer-spring t, acts on pins, to force the one part 1,
the tracer toward the edge of the sole former, and through the arm w, to the
post u, to force the other part v, of the tracer outward from the edge of the sole
former and to confine it to its guide-way o, of the bed, and the ratchet bar x, with
which the arm w, of the post u, is engaged, furnishes a bearing for holding such
arm to its work, which, while it is practically permanent, yet allows of the
engagement of the arm w, with it, to be readily adjusted to secure a greater or
lesser degree of tension on the tracer spring t, and, as a consequence, a greater or
lesser pressure upon the respective parts r, v, of the tracer, in opposite directions,
as described.
The tracer M, constructed in itself and connected to the endless chain K, and
arranged about the sole-former as above described, under the travel of the chain,
is made to move around the sole-former and, as it so travels, to follow the outline
or periphery thereof,

page_text: The tracer, in its travel aforesaid, rests upon the upper face of the raised edge o,
before referred to, and an outside raised edge a³, also of the general outline of the
sole-former, and thus is kept in a horizontal position
The tracer is provided with a fixed downwardly projecting stud b³, (Figures 8
and 16) which is so situated that, in the travel of the tracer, it will pass over, and
as it so passes over will press downwardly upon the upper rounded end of a
vertical stud c³, (Figures 13 and 16) which 18 shouldered in its length, and 18
arranged at the right hand end of the bed-piece A, in a socket of such bed-piece, in
a position to rest upon the angular clutching lever F, hereinbefore referred to, when
such lever is in its before described locked position of clutch
This downward pressure upon the stud c³ by the travel of the tracer pin 6ª, over
it, as above described causes the stud c³, to throw such clutch-lever out of its inter-
lock with the frame A, and to place it in position to be thrown by the reaction of
its spring 9, in the proper direction to unclutch the loose sliding pulley D, from the
fixed gear wheel E, of the driving shaft G, and thereby automatically stop the
further movement of the tracer and all of the other operating parts of the machine,
as will hereinafter more fully appear
The sole-former L, rests upon the top of a block N, (Figure 2) of the bed or
frame work A
This block N, along its length, has two stationary vertical pins d' d', which fit
holes e es, in the former L, and the block has a longitudinal slot f, between said
pins d² d² g³ g² are two angular shaped levers, arranged at opposite ends of the
slot, and each to turn upon a separate fulcrum-pin h², of the sole former
block N
These levers g³, at their lower ends, project toward each other and at their upper
ends they each project loosely through the top of the block N, and separate holes 1ª,
of the sole formei L, and beyond the upper surface of said pattern
The upper projecting ends of each lever gª, has an offset ' extending toward
each other, and both situated to be lapped over and to be brought to bear upon
the upper surface of the pattern-plate, by swinging the levers in the proper
direction therefor
The holes through the former plate, for the levers g³ are sufficiently large, to
allow the pattern plate L, to be freely put over and removed from the end offsets j³,
of the levers, and yet ensure to said levers a bearing against the edge of said
holes and thus a bind of the plate between the two in the direction of the length
of the pattern plate, when the levers are swung in a direction, moving their upper
ends toward each other
O is a pin, arranged for a vertical movement between the lower ends of the
angular levers g' and through the bed A
This pin O, at its upper end, has a head k³, which rests and bears upon the
upper side of the lower parts of the angular levers, and the pin at its lower end,
is hung to a handle lever P, arranged to turn upon a fulcrum 2, of a stationary
post m³, and to project from one side of the bed or frame work A, there provided
with a ratchet or toothed-bar Q, in position for engaging the lever with its teeth,
and thus securing the same against movement
A construction and arrangement of mechanism and its combination with a sole-
former, all as above described, secures by a depression of the lever handle P, and
through it, of the headed pin O, the swing of the angular arms or levers toward
each other and thus the sole-former is bound between the edges n², of its holes 23,
in a line in the direction of the length of the former and again by the offset j³, of
each lever, the former is also bound in the direction of its thickness upon the block,
and by then engaging the lever handle with the ratchet-bar Q, this bind of the
former, is made fast or secure against accidental release
Having disengaged the lever handle P, from the ratchet-bar, the lever-handle 18
then free to be operated to release the angular levers from their hold of the
former L, and thus place the levers g³, in position for the sole-former to be removed
therefrom and from the rest block N.

page_text: The clamping mechanism above described for the sole-former may be arranged
to hold the former at opposite ends of a line, running in the direction of its width
in lieu of in the direction of its length as particularly shown and described, again
in lieu of holding or confining the sole-former in either of the directions above
stated the clamping mechanism may be arranged simply to hold or confine the
sole former L, in the direction of its thickness, and at opposite ends of a line,
running in the direction of the length or of the width, of the former
The two parts of the clamping mechanism for binding the sole-former in place
as described, when operated by the lever P, work simultaneously and conjointly
Bent springs to throw the angular levers into position for the removal of the
sole-former may be used if so desired
The pins d' of the block N, over which the sole-former fits by its holes e³, act as
guides in placing the sole-former upon the block and also assist to a greater or
lesser extent in the hold of the sole-former by the clamping mechanism, and they
may be dispensed with, but obviously it is preferable to use them
The upper slider of tracer M, at its end towards and which is just above the
sole former L, is connected by a vertical swivel-pin o³, to a slide or carriage marked
with the Figure 1 and to be hereafter called carriage 1, or tracer-carriage
This tracer-carriage 1 is arranged to travel upon and horizontally along the
length of the dove-tail R, that runs lengthwise of a horizontal frame or carriage,
marked with the Figure 2 and to be hereafter called carriage 2 and in a parallel
line or direction with the longer axis of the sole-former L, and this carriage 2 of
which said dove-tail rail forms a part is supported at its parallel rails q², upon
vertical rollers on wheels p³, of the frame A, and it is arranged to travel on said
wheels, at right angles to, or in other words, directly across the line of travel of
carriage 1 upon carriage 2
There are two of the rails q and four rollers p One of the rails q* duectly
rests upon two of the rollers and the other rail enters into and rests by its side
faces against the side-walls of a wedge-shaped peripheral groove rª, in each of the
rollers
The side faces of the rails q* are made bevelling and such bevel and also that of
the side walls of the grooves of the rollers is arranged to secure a rest only of the
rail against the side walls of the grooves The axial pin of each grooved wheel p³,
is secured in place by a screw-nut and all in a manner for tightening the grooved
wheels p³, against the rails q³, so as to prevent all lateral movement or play of
carriage 2 upon its supporting wheels
S is a horizontal traverse or radius-bar, secured by a pivot a¹ to tracer
carriage 1
This pivot 8ª of the radius-bar S, to carriage 1 18 coincident with the central
line of the radius-bar along its length and this radius-bar back of tracer-carriage,
is adapted to move lengthwise through a dove-tail slice slide or clamp T, which is
axially or centrally pivoted at to, to a stationary but adjustable block U, of a
stationary rail V, of carriage 2 which rail runs in a line at right angles to the line
of travel of carriage 1 upon carriage 2 or in other words, at right angles to the
longer or longitudinal axis of the sole-former L
The stationary block U, is fastened to its carrying-rail V, by a cam-lever u³, and
with this cam-lever released, the position of the block U, on its carrying rail V,
may be changed at pleasure, by simply sliding the block U, upon the same (for
which purpose the block U and rail V, are suitably constructed) and then tightening
the said cam-lever against the rail V
The adjustment of the block U upon its rail V, as shown, is such that, the
distance between the centre or axis of the pivot connection t³, for the slide-clasp T,
of radius bar S, and the centre or axis of the pivot connection 8³, between said
radius-bar and carriage 1 equals the length of the longer axis, of the sole-former L
when the central longitudinal line of said radius-bar S, is at right angles to the
longer or longitudinal axis of the sole former For convenience in making the

page_text: adjustments of block U, upon rail V, above described the block is provided with
a pointer v³, and carriage 2 with a graduated scale w
The graduations are figured according to the distances between them and the
axis of the pivot-connection of carriage 1 to radius bar S, in a line at right angles
to the longer axis of the sole-former
The radius-bar S, has a dove-tail slide or clasp W, adapted to slide along its
length and connected by a vertical axial pivot or swivel ³, to a toothed or
racked bar X, of a carriage marked Figure 3 and to be called hereafter carriage 3
This carriage 3 is arranged to travel upon carriage 2 in the direction of its length,
that is, in a direction parallel with the direction of the travel of the tracer-carriage 1
upon the rail R, of carriage 2
The rack-bar X, which makes a part of carriage 3 and through which such
carriage 19 connected to slide W, of radius-bar S, as has been above described, 18
arranged to be moved forward and backward within a groove y³, of carriage 3,
which groove, runs at right angles to the said line of travel of carriage 3,
upon carriage 2, or in other words, in a line parallel with the line of travel of
carriage 2
This movement of the rack-bar X is, by the turning of a horizontal gear-
wheel, which 18 in position to engage with said rack-bar and is attached to a
vertical shaft a³, arranged to turn, at its lower end, in a bearing of carriage 3, and
at its upper end, in a bearing of the head, to a fixed goose neck standard y, of said
carriage 3
1
This gear-carrying shaft a³, has a horizontal and open hand wheel Z, for
turning it, and thus through its gear connection with the rack bar X, secure the
movements described of said bar upon and along its guide groove y³ of carriage 3,
and this movement may be either to the right or left, in relation to the direction of
such groove, according as may be described
This movement of the rack bar X, upon the carriage 3, enables the position of its
pivotal connection X³, and thus of carriage 3, with the radius-bar S, to be changed
in relation to the length of such bar, for an object and purpose, which will herein-
after fully appear
As is shown (Figures 14 and 15 particularly) the handwheel Z, of itself is loose
upon the axle shaft a³, and the two are connected together so as to turn as one, by
an arm a', of shaft a' which is fastened to the shaft by a pin 67, and to the hand
wheel by a headed set screw c', which passes through a circular slot d' of the flange
to the handwheel, that is concentric with the axis of the shaft a³
Tightening this set screw o³, fastens the handwheel Z to the arm a³, of axle
shaft as, and as a consequence hand wheel and shaft will, turn as one, by operating
the handwheel
Loosening the set screw c, unfastens the hand wheel from the axle shaft, and
leaves said axle shaft, then free to be turned independent of the band wheel, that
is by the swing of the arm a to right or left
·
The turn of the shaft a³ by the hand wheel causes, as has been before stated a
change in position of the pivotal-connection X², between carriage 3, and radius
bar S, and the same result is produced by the swing of the arm a when loosened
from the hand-wheel and this latter change of said position is for a purpose which
will hereinafter fully appear and for accuracy in measuring such change of position
one edge of the circular slot is graduated as shown at f' and the arm a', is
provided with an index-pointer g'
6, is a series of notches at equal distances apart around the upper edge of the
band-wheel Z, and c³ is a spring lever or catch which is arranged upon the goose
neck standard Y and located, in a suitable position and manner, to engage with
such notch of the series of the notches 63, of the handwheel Z as may be in position
therefor, through the turning of said band-wheel
This engagement between the lever-catch o³, and a notch b³, of the handwheel Z
while such engagement continues, holds the wheel stationary, and consequently, it

page_text: similarly holds the rack X, stationary and against movement upon carriage 3 but,
when such engagement is released or broken, by withdrawing the lever catch c³,
the hand wheel is then free to be turned, to slide the rack bar upon carriage 3, as
before stated
The periphery of the hand wheel Z, at and along the length of the notches
thereon, is marked at equal distances apart with figures, that commence at the
night with Figure 8, and proceed toward the left in regular order and succession to
and including Figure 13 and thence continuing toward the left again in regular
order and succession with Figure 1 to Figure 14 inclusive and this placing of these
Figures upon said hand-wheel, is such, that, when any one of the same is at the
point of the index finger-piece e³ fixed upon the left hand side of the goose-neck
standard Y, a notch 6 of the handwheel, will be in position for the engagement of
the lever-catch therewith, and such a notch, that, in the then operation of this
machine, the sole cut out, will be for a length belonging to such number, and of a
proportionate width through its whole length corresponding to such length of the
sole, and therefore in the use of the machine, this relative notching and figuring of
the hand-wheel represents or stands for the varying sizes of boot and shoe sole,
both as to their length and width, all as will hereinafter be fully described and
thus more fully appear
f is a sleeve which surrounds and turns upon the hand-wheel shaft a³ below
its hand wheel
This sleeve is provided with a hand lever A which passes up through the open
hand-wheel and thence over the upper side of the wheel, where it is provided with
a spring-lever catch g³ adapted to engage with a notch of the series of notches h
arranged at equal distances apart, for a portion of the periphery of the handwheel
and for that portion thereof, not covered by the notches 6 and figures before
described
These latter notches h³ have on the edge of the wheel figures placed against
every other one to wit, against the right hand notch, three zeros (000), the
second notch to the left of that one zero (0) and then figures fiom one (1) to
eight (8) inclusive
In the use of this machine, this numbering of the hand wheel, represents or
stands for the varying widths of boot and shoe soles, all as will hereinafter be fully
described and thus fully appear
This sleeve f³ of the hand wheel shaft a³ carries a horizontal gear-wheel 2*
arranged to mesh into a horizontal toothed or rack bar which is secured to a
plate slide B², arranged to move in a dovetail groove or way c³ of carriage 3
a line parallel with the travel of such carriage upon carriage 2, as has been herein
described
In
The turn of the gear wheel through the swing of the lever handle A³,
independent of the hand wheel upon the rack bar of the plate slide B³, either to
the right, or left, in relation to the length of such rack-bar, moves in each case, the
plate slide B³, in and along its guide-way, in the corresponding direction, while the
handle-end of the lever, moves in the reverse direction
The position of plate slide B³, in its guide-way is thus changed or adjusted, and
with the lever-handle A', then engaged with a notch of the series of notches h³
upon the hand-wheel provided for its engagement therewith, it will be so
maintained and held, except it be changed, as hereafter stated
The turn of the gear wheel & through the hand wheel, either to the right or left
upon the rack bar X which is adapted to slide across carriage 3, moves said rack
bar in a corresponding direction and if the lever handle A, be engaged with the
hand-wheel the gear-wheel 13, connected with it, will also be turned upon its
rack-bar in a corresponding direction and thus the plate slide B' moved in its
guide-way, relative to the length of such guide-way in a corresponding direction
that is, to the right, if the hand wheel, is turned to the right, and to the left if the
hand-wheel is turned to the left.

page_text: F
The moving of the handle-lever A³, either to the right or left, moves only the
plate-slide B³, and this movement of the slide 18, in each case, the reverse in
direction to that of the handle-lever.
The swing of the hand-wheel to the right or left, moves, not only the rack-bar X,
upon carriage 3 either to the right or left, as the case may be but also the plate-
side B' to the right or left as the case may be, these respective movements being
at right angles to each other
In the operation of this machine, a change of position of the plate-slide B³, upon
carriage 3, through the handle-lever A affects the sole being cut, in relation to its
width only, and a change of position, of the rack-bar X, upon carriage 3 through 1
the hand-wheel affects the sole being cut, in relation to its length, but as, when
such change is made, the plate-slide B-18 also moved, by such movement of the
plate-slide, the sole being cut in its width, is also affected, proportionately to the
change in its length and whatever may be the change, in width, made, by a change
of position of the plate-slide through the handle-lever, all will appear more fully
hereafter
This plate-slide B', has a horizontal traverse or radius-bar C pivoted or
swivelled to it and the axis of such pivot ³ coincident with the central
longitudinal line of said bar
This radius bar c', in its length is provided with two dovetail clasps D³, and E³
The clasp D is adjustable as to the length of the radius bar C, and when so
adjusted, is secured by a cam-lever and the clasp E is free for the radius-bar C
to slide within and through it, and is concentrically pivoted at y' to the front end
of a carriage, marked with Figure 4 and to be hereafter called carriage 4
This carinage 4 carries a cutter-bar y³ as will hereinafter appear and is arranged?
to slide within a dove-tail way Fª or carriage 3, in a line at right angles to the line
of travel of carriage 3 upon carriage 2, or in other words, in a line, parallel with
the line of travel of carriage 2 upon the frame A
The adjustable and fixed clasp D' of the radius-bar C is concentrically swivelled
at m³ to a slide-block G adapted to move upon a horizontal dove tailed rod H* of 3
a frame I³, arranged to travel in conjunction with carriage 3, but in such travel, to
move along and upon the length of a stationary horizontal guide-bar J2 of the
supporting frame A, of the machine, in lieu of along and upon the length of
carriage 2 as is the case with carriage 3
This guide bar J* is at the rear of the frame A
which acts as a guide to the longitudinal slide of the
above carriage 3
And the dovetail rail H* 3
clasp G² on radius-bar G†³ is
This guiding-frame I' is stationary in relation to the herein described travel of
carriage 2
But moves in conjunction with carriage 3, on carriage 2
Carriage 4, has a standard K³, carrying in its upper part a short horizontal 4
shaft n³ which is in a parallel line with the movement of said carriage 4 upon its
guide ways F and at its rear end it is connected by a universal joint L' to one
end of a horizontal connecting shaft M' made in two parts telescoped together and
longitudinally splined, and at its rear end connected by a universal joint N¹ to the
Journal of a small gear-wheel 08 arranged to turn in bearings of the stationary
bracket P² of the frame A and to be driven by the fixed gear-wheel E, hereinbefore
referred to, of the driving shaft C
This connection, through universal joints L³, N° and longitudinally splined
connecting shaft M with the driving mechanism above described, secures the
revolution of the shaft n³ in any and all movements of carriage 4 in its guide- 5
way F and of carriage 4 with carriage 3 upon and along carriage 2
The horizontal shaft n³ of carriage 4, has a vertical gear-wheel o³ with which
meshes a smaller gear wheel p³ carried, by an upright support g³ which is arranged
for an up and down movement upon carriage 4, and in such movement, to be
guided both by a vertical guide-post of the upper side of carriage 4, and, by the 5
vertical and under tubular extension of the support 9 which passes through a
guide tube t³ projecting downwardly from the under side of carriage 4.

page_text: The downward movement of the gear-wheel support
connection with the gear wheel o³ on carriage 4
places its gear p³ into
The movement is secured by a cam-lever us which has a fulcrum at v³ of the
head stock K of carriage 4 and is arranged to work by its cam edge against and
upon the upper end of the up and down moving support q³ for the cutter-bar and
thus to place the cutter-bar y³ in its operative position and then, by its square
end Ws to hold it there and against the action of the spring which is used to
throw the cutter-bar upward and out of its operative position
The cutter-bar y³ is released from the spring a³ by turning the cam u³ so as
remove its square end from its bearing on the upper end of the support o³ carrying
the cutter-bai and its attachments
The gear-wheel p³ of the vertical moving support ³ above described is
eccentrically pivoted to the upper end of a vertical connecting rod which
at its lower end, is pivoted to a collar a' that is secured, by a set-screw b' to a
cylindrical-rod c placed within the downward tubular extension 8 of the gear-
support in a manner to be alternately moved up and down therein under the
rotation of the gear-wheel p³ to which it is eccentrically connected as above
described
This vertical reciprocating rod o has swivelled in its lower end the vertical
cutter-bar which continues downward through the guide-tube for such rod and
projects at the lower end thereof, where it enters and passes through a piesser foot-
piece d'
This foot-piece d' by its sleeve portion et turns around and plays vertically
within the guide-tube 83 and in its upward play it works against a spiral-spring f
which surrounds the outside of said guide-tube, and is there confined endwise
between a shoulder g' of the guide-tube and a collar h of the foot-piece, which
collar loosely surrounds said guide-tube, and said foot-piece is held against escape
from the guide-tube, under the downward pressure of the spring f by the abutment
of its said collar against a shoulder 2' at the extreme lower end of the guide-tube 8³
The cutter-bar y at its lower and projecting end, has a square cutting-edge and
the portion of the cutter-bar which plays through the foot-piece and its tubular
portion as the cutter-holder is reciprocated as aforesaid, is flat sided and its guide-
hole in the foot-pieces, is correspondingly shaped
The under face of the foot-piece is flat and it has an edge-lip * which runs in a
line, coincident with the line of the straight cutting edge to the cutter-bar and
furthermore is, at the rear of, or, in other words, behind the cutting-edge in its
travel to cut a sole, and in such position, situated to follow and travel, in the line
or slit of the cut made by the cutting-knife, all as and for a purpose as will herein-
after more fully appear
Qis a horizontal flat block resting upon the forward projecting part R³ of the
main-frame A
This block is the cutting-block of the machine, and its cutting-surface, is made
of a layer or layers of paste-board or other suitable material, which will not injure
the cutting-edge of the knife
The cutting block Q is below the cutting-bar y which, in its vertical
reciprocating movement before described, cuts against the block, and again said
block is of such shape and size, as to present a surface for the cutter-bar to cut
against, in any and all positions of the cutter-bar, under the operation of this
machine, as will hereinafter fully appear
The leather from which a boot or shoe sole is to be cut, is placed upon this
cutting block Q and there it is clamped against the upper surface of the cutting-
block and between it and the under surface of a plate s³ which makes one, and the
upper jaw of a clamp, to which the cutting-block is the other, or lower jaw,
securing and holding the leather in position upon the cutting-block
for
The plate or upper clamp jaw s³ is of the general outline of a boot or shoe sole
and of a size considerably smaller than the smallest size of sole to be cut in the
apparatus

page_text: The clamp-jaw 8ª 19 carried, as hereafter described, at its ends, upon and between
the upper ends of two similar vertical C-shaped arms or levers T" which are
located in a vertical plane preferably coincident with the central line of the
cutting-block from end to end
The cutting block is below carriage 2 (figures 4 and 8) and in the position of
carriage 2 shown in the drawings, figure 1, A portion of the width of the cutting-
block is necessarily covered by said carriage
The upper end of each C-arm or lever enters into a socket and abuts against
each end of a block that is secured to the upper side of the upper clamp-jaw s³
and thence, each lever passes around the end of the platten or cutting-block to
and below the under side thereof, where each lever 18 hung upon separate
horizontal fulcrum pins m' secured in a bracket frame U'
The block V has a vertical stem w projecting downward from its under side
and it together with said stem is arranged to be moved up and down and in such
movements, playing through a vertical guide-tube of brackets * which are
attached to the under side of the supporting platten for the cutting-block.
Each C-arm or lever extends from its fulcrum pin m* toward the other and the
outer end of each lever bears against separate cam edges ³, both of similar shape,
but running in opposite directions and each carried by a separate vertical gear-
wheel A³.
These vertical gear-wheels A³, turn upon a common horizontal axle shaft n'
secured at its opposite ends to the fulcrum bracket U carrying the C-levers and
they are driven by a common vertical bevel gear-wheel of placed between and
engaging with the teeth of each of them
The bevel gear wheel o' turns upon a horizontal axle shaft pt that, at one end,
is arranged to play in and out of a socket g' in a collar which swivels or rocks
upon the axle n' of and between the vertical gear-wheels A³ and at the other end,
it terminates in a sleeve s' arranged to turn or rock upon the horizontal extension t
of the driving shaft C of the machine
This extension has a bevel gear-wheel u meshing with a bevel gear-wheel
carried by the bevel gear wheel of herein before described as meshing with the two
vertical gear-wheels A³ carrying the cam-edges
The shape of each cam-edge is such, that, for a portion of the rotation of each
cam, the cam will hold the C-lever, resting against it engaged with the socket of
the upper clamp jaw S2 and for another portion will allow such arm to be
disconnected from such socket, and to fall back and away from the cutting surface
of the cutting block, either by the action of a bent spring which is arranged to
bear against each C-arm in a proper direction to move it from the upper jaw, as
the shaft of the cam allows such movement to occur or by the weight of the lever
or arm itself
The cams are rotated by the pinion gear-wheel of which meshes with the
carrying gear-wheels A³ and is connected with the shaft tas has been described
and the cams are of shape for each of the C-arms to be placed out of the course
or travel of the cutter bar about the cutting-block in the operation of the
apparatus to cut a sole from the leather placed upon the block, in season, for such
cutter to cross the pla e or position of such C-arm, were it in engagement with
the clamp-jaw, while at the same time the other C-arm is in its position of
engagement with the clamp-aw, and to again connect such C-arm with the
clamp-jaw after the cutter-bar has passed along in its course a sufficient distance to
allow of it and all without danger of interference between the two
As the carrying C-aims for the upper-clamp jaw S³ are connected to a common
holder or block V2 adapted to be moved up and down through stationery
brackets y of the bed or frame-work it is plain that, depressing the holder V the
upper-jaw can be placed in close contact with the leather etc upon the cutting-
block to secure such leather in position thereon, and again by lifting the holder V* 5
the upper-jaw can be placed out of contact with the leather etc. upon the cutting-
block and thus the leather be released for removal

page_text: The lowering of the upper clamp-jaw S is secured through the depression of a
treadle B³ connected by a rod C³ having a spring D³ intermediate of its length, to
the lower end of the downward projecting stem W of the carrier-block Vs for the
C-arms of the upper clamp-jaw, and this depression is against vertical spiral
springs E³ connected, at their upper ends to the stationary brackets Y' of the bed A
and at then lower ends to a cross piece of the vertical stem W' of the carrier-
block Ta
The raising of the upper clamp-jaw is from the reaction of the spiral springs E³
and this jaw when brought into position to clamp the leather upon the cutting-
block is 80 held by engaging its operating treadle B³ with the proper tooth of a
stationary ratchet or toothed-edge W' on a post F, suitably located therefor
In this raising and lowering of the upper clamp-jaw, the mechanism for rotating
the cam edges Z' from the rotation of a driving shaft, connected thereto at the bevel
gear-wheel of not only moves up and down with the upper clamp-jaw, but, at the
same time, keeps its several connections with each other and the driving bevel genr
wheel u intact, because of the rock of the axle-shaft p, which carries the bevel
gear wheels o, v, upon the driving shaft C and of the in and out play allowed to
said axle shaft 2 in its rocking support 9' between the vertical gear-wheels A³ and
upon the axle-shaft n' of said wheels, all of which allows said several parts to
accommodate themselves to the varying distances between the axes of the driving
shaft C and of the axle-shaft n' carrying the vertical gear wheels A³ caused by the
up and down movement of the axle-shaft n in raising and lowering the upper
clamp-jaw and the carrier-block V2 for the arms of the suspension for said jaw
An arrangement of clamping jaws such as described for securing the leather etc.
in position (to be operated upon by a cutter or marker of a grading-apparatus)
obviously permits of a continuous movement of the cutter or marker about the
leather etc held between the clamps, without interference between it and the
holding devices for the upper clamp-jaw which are across its path or course and
the upper clamp jaw, is, at all times, held securely in place, at least, by one, if not
by both parts of its Faid holding devices
The C-arms or levers T carrying the upper clamp-jaw as described are along the
length of the clamp-jaw, but plainly they may be as well arranged across the
length of the jaw, or, in other words, in the direction of the width of the jaw
The springs described, for throwing the C-arms away from the upper clamp-jaw
may be dispensed with, and the same result accomplished by weighing the said
Carms
Again-the cutting block, which is the lower jaw may be arranged to be lifted
toward and lowered from the plate or upper clamp-jaw in a manner for instance
substantially similar to that described for the upper clamp-jaw that is by treadle
and springs and the upper clamp-jaw then made stationary or arranged to be lifted
and lowered, as has been described
The C-arins at their bearing ends or faces, upon the cam-edges have friction-
rollers to run upon said edges and each roller it is preferable to have carried in
a block secured in position by a screw and adapted to be adjusted to place the
roller to its proper working position by a set-screw, all, as is obvious, without
further explanation
In a machine, constructed as above described, through the revolution of the
diving pulley D, if clutched to the driving-gear-wheel E, of the machine, the
tracer M is carried around and about, strictly following the edge of the sole-
former L and the cutter-bar y³ is reciprocatingly moved up and down in relation
to the cutting-block or platform Q³
In all the lines and directions of this travel of the tracer, which are parallel
to the longer axis of the sole forme, the tracer-carriage 1 similarly moves upon its
guide-rail R of carriage 2 and through the radius-bai connection S of curiage 2,
with carriage 3, and through the location of carriage 4, or cutter-bar carriage, on
carriage 3, cariages 3 and 4 are moved in unison in a direction corresponding to
the said direction of travel of the tracer-carriage 1 upon carriage 2

page_text: Again in all the lines and directions of this travel of the tracer M which are at
right angles to the longer axis of the sole-former L tracer carriage 1 operating upon
carriage 2, forces such carriage in a corresponding direction on the frame A, and as
carriages 3 and 4 are both upon carriage 2 such carriages are carried in a corre-
sponding and equal direction, so far as such transverse movement of carriage 2 of
itself, is concerned
As to this longitudinal travel of tracer-carriage 1, on carriage 2, if the distance
between the pivotal-points s³, 1 of connection of radius-bar S to carriages 1 and 2,
when such pivotal-points of connection, are in a line running at right angles to the
longer axis of the sole-former L, be equal to the length of such longer axis of the
sole-former and, if the pivotal point of connection a³ of carriage 3 with said radius-
bar S, be adjusted and set through the turning of the hand-wheel Z, as has been
described, so as to be coincident with the pivotal connection S³ of 1adius-bar S,
with tracer-carriage 1, then, the travel of carriage 3, upon carriage 2, in the corre-
sponding direction of the travel of tracer-carriage 1, on carriage 2, is exactly equal
in length to the travel of the tracer-carriage 1, on carriage 2, or, in other words,
exactly equal in length to the longer axis of the sole-former L, and, as a conse-
quence the cutter-bar y³ will be carried in a corresponding direction, exactly equal
to the length of the sole-former
Now, if this coincident relation of the pivotal connections 8, x², of carriages 1
and 3 be changed, by adjusting and setting through the hand wheel Z, as described
the pivotal connection a³, of carriage 3, on radius bar S, so that its distance, from
the pivotal connection t³, of carriage 2, on radius-bar S, shall be greater or lesser
than the distance of the pivotal connection &³, of carriage 1, on radius bar S, there-
from then the travel of carriage 3, upon carriage 2, in the corresponding direction
of the travel of tracer carriage 1, on carriage 2, if such distance be greater, will be
increased and if such distance be lesser, will be decreased in length, as to the length
of travel of tracer carriage 1, and as a consequence, the cutter bar, in its movement
in a similar direction will be correspondingly affected and thus be made to pass
over a greater or lesser distance, as the case may be, than the whole length of the
sole-former
In all the movements of carriage 3, above described, in reference to the line of
travel of tracer-carriage 1, upon carriage 2, the travel of the pivotal-point ³ of
connection of carriage 3, and radius bar S, is always in a line, parallel to the line
of travel of tracer-carriage 1, on carriage 2, or in other words, in a line parallel
with the longer axis of the sole-former L, and furthermore, whether its adjustment,
(that is, the adjustment of pivot a³) as aforesaid, be, at a greater or lesser distance
from the pivotal connection t of radius-bar 8, on carriage 2, than the distance of
the pivotal-connection S₁ of tracer-carriage 1 on said radius-bar therefrom, the
pivotal connection X³ of carriage 3, with radius bar S, in the whole length of its
said travel, is, always, at the same relative perpendicular distance from pivotal-
connection S" of radius-bar S, to tracer carriage 1, and also from the pivotal-
connection 2, or radius bar S, to carriage 2, and thus, at any and all portions and
for the whole length of the movement of the tracer-cairiage 1, in lines parallel with
the longer axis of the sole former L, the cutter-bar y³ is given a movement, in the
corresponding direction, which, as to any and all portions, or the whole of its
length, and whether its whole length, be equal or greater or lesser than the longer
axis of the sole-former L, is, at any and all times, in an exact and direct proportion
to the aforesaid movement of the tracer-carriage
In this operation of carriages 1, 2, and 3, the radius-bar S slides upon and
through the clasp T, pivoted to carriage 2, and thus lengthens or shortens, as it
were, as the distance of the pivot S³ of the radius-bar S, to carriage 1, from the
pivot t³ of clasp is greater or lesser in length, under the travel of the pivot which
connects carriage 3, to said radius-bar, in lines parallel with the length of the sole-
foi mer
The operation above described of the tracer-carriage 1, through radius-bar S, on
carriage 3, obviously, affects the length of travel, in one direction of the cutter-

page_text: bar (that is, in the direction of the longer axis, of the sole former L) and it
thereby enables a cut to be obtained from the cutter-bar y³ in such direction along
a line, having either an equal or a greater or a lesser length in relation to the
length of the sole-former
In order, that this effect upon the travel of the cutter-bar y³ in relation to the
longer axis of the sole former, may be represented with absolute accuracy and
certainty, so as to obtain from one and the same sole-former L, a regular and
systematic grading of the operation of the cutter-bar y³ in relation to the length of
the sole-former, in accordance with the usual custom of grading boot and shoe
soles as to their length, the hand wheel Z, through which the adjustments for such,
purpose are made as aforesaid, is provided with the series of notches and gradua-
tions b before described
In this regard, as before stated, the figuring of these notches on hand-wheel Z,
stand for the varying sizes in length of boot and shoe soles, and each notch,
between each two of the notches to which the figures pertain, stand for the half
sizes, between the sizes represented by the numbers which pertain to the preceding,
and following notches, as has been described
In connection with this adjustment, through hand-wheel Z, of the pivotal-
connection X³ of carriage 3, to radius-bar S, which connects tracer-carriage 1 and
carnage 2, a similar further change or adjustment thereof is secured by loosening
the set screw c" which fastens arm a' of axle a³ to hand-wheel Z, and swinging
said arm either to the right or left as may be desired, thus turning the axle a³ and
its gear-wheel, slide the rack-bar a along its guide-way y' of carriage 3 Having
thus moved said rack-bar as described by which the position of pivot-connection
of carriage 3 with radius-bar S, is changed the set screw c is tightened fastening
the arm a to hand wheel, when by means of the hand wheel the adjustments of
said pivotal connection may be proceeded with in accordance with the arrange-
ment of notches b* on said wheel
This adjustment is, as is obvious independent of the adjustment through the,
hand wheel Z and again g by it plainly when made the pivotal connection a³ of
carriage 3 to radius bar S can be given such a position relative to the pivotal con-
nections & of tracer carriage 1 on said radius bar and of said radius bar to
carriage 2 and to the then after adjustments of the same pivotal connections in
accordance with the notches and graduations of the hand wheel Z as to secure
without a change of the sole former the same effect as if another former was
inserted of an increased or decreased length as the case may be and that this effect
will be in accordance with the increase or decrease in the distance of travel given
by such adjustment of the pivotal connection ³ of carriage 3 to radius bar S in
relation to the length of the sole former L under the travel of the tracer about the
same
As to the travel of carriage to and with it the travel of carriages 3 and 4 at
right angles in relation to the longer axis of the sole former L as bas been been
herein described if the pivotal connections k³ 3 of radius bar C to the plate slide Bª
of carriage 3 and to carriage 4 be coincident with each other, then carriage 4 or
cutter bar carriage remains stationary upon and has no movement across carriage 3
for and during any and all portions of the travel of such carriage 3 with carriage 2
in a direction across the longer axis of the sole former L and as a consequence the
cutter bar y³ will thus be carried in a direction corresponding and exactly equal to
the width of the sole former
-Now if this coincident relation of the pivotal connection of carriages 3 and 4
be changed by adjusting and setting either through the hand wheel Z or through
the handle lever A³ or through both, acting upon the slide plate B', of carriage 3,
as described, the pivotal connection k³ of such plate B' and thus of carriage 3, to
radius bar o, in relation to the pivotal connection y' of carriage 4 to said radius
bar, so that the distance, between the latter pivotal connection k³ and the pivotal
connection m³ of same radius bar to the frame 1ª (which frame is stationary as to

page_text: the transverse movement of carriage 2, on frame A, but moves in conjunction with
carriage 3, on carriage 2,) shall be, greater or lesser, than that of the pivotal
connection of carriage 4, to radius bar o², then, under the travel of carriage 3,
with carriage 2 in the direction of the width of the sole former, the movement of
éarriage 4, in a corresponding direction, if such distance be greater, will be
increased, and if such advance be lesser will be decreased in length, as to the whole
length of the travel of carriage 2 at right angles to the length of the sole former
and, as a consequence, the cutter bar y in its movement in a similar direction will
be correspondingly affected, and thus be made to pass over a greater or lesser
distance, as the case may be, than the whole width of the sole former
- In this operation of carriages 3, and 4, relative to each other, the radius bar C
slides upon and through the clasp E, pivoted to carriage 4, and thus lengthens or
shortens, as it were, as the distance of the pivot k³, of radius bar c, to carriage 3,
from the swivel stud m³ of clasp G on frame I*, is greater or lesser in length,
under the travel of pivot y which connects carriage 4, to said radius bar upon
carriage 3
The operation of carriage 4, on cutter bar carriage, in relation to itself and to
the transveise travel of carriages 2, and 3, on frame A, as above described, and
which primarily arises from the travel of the tracer around the sole former as
described, obviously affects the length of travel in one direction of the cutter bar,
that is, in the direction of the width or shorter axis of the sole former, and thereby
enables a cut to be detained from the cutter bar y³ in such relation along a line
having either an equal or a greater or a lesser length in relation to the width of
the soleformer
In order that this effect upon the travel of the cutter bar in relation to the
shorter axis, or the width, of the soleformer, may be represented with absolute
accuracy and certainty so as to obtain from one and the same sole former, a regular
and systematic grading of the operation of the cutter bar in relation to the width
of the sole former in accordance with the usual custom of grading, boot and shoe
Boles, as to their width, the hand wheel is provided with the series of notches and
graduations before described and the handle lever A³ as before stated, applies to
such notches and graduations
Through this bandle lever the adjustments, as to the width of movement of the
cutter-bar, can be obtained independently, of the adjustment as to length of
movement to the cutter-bar, while with the handle lever, interlocked with the
hand wheel the adjustments as to width of movement to the cutter-bar are made
in proper relation to the adjustments as to the length of movement to the cutter
bar, when the adjustments as to the length in such movements, are made through
the hand wheel
The independent adjustment as to the width of the movement of the cutter-bar
above described enables any desired width of movement to the cutter bar to be
obtained in relation to any adjustment as to the length of movement of the cutter-
bar through the manipulation of the hand wheel
In regard to the notches and graduations of the hand wheel, for the width, as
before stated, they stand for the varying sizes in width of boot and shoe soles, and
each notch, between each two of the notches, against which the figures are placed,
stands for the half sizes, between the sizes represented by the figures which are
against the notches at each side thereof
In the mechanical connection, herein shown and described between radius-bar Cª
and carriages 3 and 4 and frame 12, the perpendicular distance relative to carriage 4,
between the pivotal connections y' m³ of radius-bar Cª to carriage 4, and to frame I'
18 the greatest, when the line through said pivotal connections is at right angles to
the transverse line of travel of carriages 2, 3, and 4, across frame A, and the least
when the pivotal connection y' of radius-bar C³ to carriage 4, is at either end of the
full length of the transverse movement of said carriages.

page_text: A machine constructed and arranged as has now been fully described in detail
and as shown in the drawings embraced in plates 1 (one) to six (6) inclusive 19
handled and operated as follows
The leather, from which a boot or shoe sole 18 to be cut, 18 placed upon the
cutting-block Q³, and then the clamping-plate S³, is brought firmly and rigidly down
upon it through the treadle B' and there secured by catching the treadle in the
proper notch W* of the post F³
The hand-wheel Z, is then turned, until the number of the size as to the length
of the sole to be cut is at the index-pointer e when the hand-wheel is bolted
against further movement, and the handle-lever A³, 18 swung to similarly bring it
to the number of the size as to width of the sole to be cut, when it is secured
against further movement
These preparations being completed and as the machine 18 constructed, before
proceeding to put the cutter-bar y³ into operating connection with the universal
Jointed connecting shaft m³, it is preferable to have the cutter, if not at the rear
side, of the clamp plate S', midway between its ends, first brought to such position,
which can be secured accomplished, through the hand-crank A, if its shaft B', and
bevel gear wheel C, be put into connection with the bevel gear wheel D', of driving
shaft C
The shaft B', of hand-crank turns in bearings of the bed-plate and it is free to be
slid into and out of connection with the bevel gear-wheel D', of driving shaft, and
secured in either position by interlocking the forked lower end n' of a vertical
pink which plays through and projects above the bed-plate A, with one or the
other of the two circumferential grooves I' of said shaft B7 respectively located on
said shaft, one, for receiving said pin when the shaft is engaged, and the other when
the shaft is disengaged -
The cutter-bar y being in a position described its gearing mechanism o³ pª is
now put into connection and made secure against escape from such connection
through the clam-lever u³, as has been described
In so placing the cutter-bar y into operating connection, have the under lip,
of the presser foot behind the cutting-bar y' in its line of travel when the machine
18 driven, and the presser-foot in a line substantially parallel to the line of direction
of the clamp-plate s³, at the location of the presser-foot, also the presser-foot firmly,
at rest upon the leather, and the cutting-bar adjusted so as to have a length of
throw, when operating, sufficient to pass through the entire thickness of the leather
which is clamped upon the cutting-block q' and from which it is desired to cut a
sole of the size, length and width, indicated by the previous adjustments, of the
handwheel Z and handle A*
Now, on A clutch-of the driving-pulleys through the lever F, and a set thereby
of the clutching-lever against its holding shouldered block h and under the pin c
in the pathway of the tracer M, the machine is put into operation
This operation consists in substance
First, in a continuous travel of the tracer M about the edge of the sole-former L
Second, in a continuous travel, because of such travel of the tracer, of the cutter-
bar in a corresponding direction over the surface of the cutting-block Q, but
this travel, in such direction of the cutter-bar, is regulated or affected as to
width and length in accordance with the principles of operation of the several
carriages 1 2 3 and 4 and radius-bars S, C' and their respective connections
together, as has been herein described-and
Third, in a continuous reciprocating movement of the cutting edge against and
through the leather, whereby, the leather, is cut in a continuous line with the
direction of travel of the cutter-bar as aforesaid, and as it so cuts, the cutting edge
18 constantly surrounded by the presser-foot d' which not only drags and presses
upon the leather, but by its edge ' entera into and follows along the line or cut, at
the rear of the cutting edge and causes thereby the cutting edge of the cutter
bar y, at any and all times, to be presented, in a line with the line of direction of
the cut, which is to be made in the leather by it, because of its said travel from the

page_text: movement of the tracer While these several movements are occurring the levers T
hida g the upper climp-plate S move the one after the other into and out, of such
holding position, all as has been described, and on the completion of the travel the
trace, about the sole former, the tracer by its stud be forces down the pin o' and
thus releases the clutching leaver F from the shouldered block h and to the action
of its spring g, which throws said lever in the proper direction to unclutch the
driving-pulley D from the gear-wheel E or driving-shaft C whereby the machine
15 automatically stopped and the cutting of the sole is finished
The cutter-bar y is now put out, of operating connection by releasing its holding
cam-lever u³ as has been described, and the upper clamp-jaw is thrown up by dis-
engaging the treadle B³, and setting the carrying levers T-for said clamp-jaw S*
fiee to its lifting springs E³, and on the removal of the sole cut the machine is again
ready for another operation as before, and so on
The foot-piece d' although herein described, as constructed and arranged to press
or drag upon the leather as it is cut, and also to enter the line of cut, may be con-
structed and arranged for either one of its said operations only, and still secure the
presentation of the cutting edge to the material on a line, at all times, coincident
with the line of cut by the cutter-bar, but it is as well and better, to combine and
use them as described.
As herein described and shown the machine is arranged for its automatic stoppage
with the tracer at one side of the shank of the sole-former L, but, obviously it may
be arranged for similar automatic stoppage at all points in the line of the travel of
the tracer about the sole-former, according as may be found desirable in the use of
the machine for cutting out parts of a sole, as for instance, balf soles.
In this machine to substitute one sole former for another, it is necessary to draw
the tracer back from contact with the edge of the sole-former or to otherwise
remove it from such contact
For so drawing the tracer back the lever E on carriage 2 and the block F7
pivoted to post G7 of the bed-plate A are provided and and operated as follows
Fust, bring the tracer to the rear edge and midway between the ends of the
sole pattern-next place the inner end of the horizontal lever E' located at the
rear right hand corner of carriage 2, back beyond the block F and then swing
this block into position for its rear face to make a rest and fulcrum to the inner
end of said lever-Now, with the hand, pull or push backward upon said lever,
which draws the several carriages and tracer backward, and when the tracer is
sufficiently removed from its bearing against the edge of the sole pattern L interlock
said lever with the under side of carriage 2, which secures the carriages and traces
against returning and the tracer from its bearing against the edge of the sole
pattern
Now, with the lever P at the right of and under the bed plate unfasten the sole
pattern, and having removed it, insert the one to be substituted for it and then
with said lever P clamp and secure such sole-pattern in place-In placing a sole
pattern in the machine, take care that its general outline corresponds in direction
to that of its rest block N and that the inside of its shank is toward the rear of the
machine
Having thus placed and secured the sole pattern, now release the lever E' by
which the carriages and tracer were drawn back, and holding it firmly in the hand,
let the carriages and tracer easily and gently back into operating position, and be
sure that the fulcrum block F' for said lever E7 18 swung out of the horizontal
plane of travel of carriage 2
In this machine as the hand wheel Z is notched and numbered upon its upper
edge the grading as to length, is by thirds of an inch, that is, as between the whole
Bizes which the machine is capable of cutting, the differences in length of the soles
will run in thirds of an inch for each size
In order to so grade, the distance, between the axis of the pivot Sª connecting
radius bar S to carriage 1 and the axis of the fulcrum t' of such radius bar upon
carriage 2 must exactly correspond to the length of the sole pattern of the machine.

page_text: If desired to grade as to length, in fractional parts of an inch, either less or
more than a third of an inch, then the axis of the fulcrum of the radius bar upon
carriage 2, must be set, if such fractional part of an inch be less than a third of an
inch, farther from, and if such fractional part of an inch be more than a third of
an inch nearer to the axis of the pivot S connecting said radius bar to carriage 1
For instance, if the sole pattern be 10 inches long, and grade desired between
sizes as to length, be quarters of an inch, making 40 sizes to the length of a pattern,
divide 40 by 3 which gives 13, as the graduation of the scale wat which the
pointer attached to the clasp U carrying the fulcrum t of radius bar S must be
set, in order to have the machine grade between the sizes as to length in quarters
of an inch.
To set the clasp U, first release it from its radius bar and then move it thereon
until its pointer is brought to the proper graduation of the scale w³ when fasten
it to the radius bar
The releasing and the fastening of this clasp is by the lever u³ fulcrumed
upon it
Follow this rule for any other fractional part of an inch in the sizes as to the
length
Again in this machine, as the band wheel Z is numbered upon its outer edge, the
grading as to width, is by eighths of an inch, that is, as between the whole sizes,
which the machine is capable of cutting, the differences in the width of the sole,
at the ball, will run in eighths of an inch and an eighth of an inch for each sizə
In order to so grade, the left hand edge of the clasp D* upon the radius bar C",
must be set to the graduation on such radius bar, corresponding in number to the
full width at the ball of the sole pattern
If desired to grade as to width in fractional parts of an inch either less or more
than eighths of an inch then the left hand edge of this class D' must be secured
upon the radius bar C if such fractional part of an inch be less than an eighth of
an inch, farther from and if such fractional part of an inch be more than an eighth
of an inch nearer to the pivotal connection between said radius-bar C and
plate side B operated by the hand lever A³ of the hand wheel Z has been
explained
For instance If the sole pattern be 3 inches in width at the ball and grade
desired between sizes as to width be by twelfths of an inch, making 36 sizes to the
width of pattern divide 36 by 8, which gives 4 as the graduation of the scale
upon radius bar C, at which the left hand edge f of clasp D' must be set for the
machine to grade between sizes as to width in twelfths of an inch
To so set this clasp first release it from the radius bar, and then move it upon
such bar until its left hand edge is at the proper graduation of the scale, on the bar
when fasten it to the bar
The releasing and fastening of this clasp is by the lever I', fulcrumed upon it.
Follow this rule for any other fractional parts of an inch in the sizes as to
widths
H' figures 8, 13, and 17 is a pulley fastened to driving shaft C under the bed
plate A and J is a brake shoe shaped to partially surround the pulley H
This brake shoe is carried by a weighted lever K' having fulcrum at M' and
connected by link L' to a lever M' having fulcrum at n² and arranged under and
across the direction of the swing of the clutching lever F
This mechanism operates in the unclutching of the driving shaft C or pulley D
and gear wheel E and because of the swing of said clutching lever F to put friction
by the brake-shoe J' upon the pulley H7, and thus positively check and stop the
machine
The machine illustrated in plates seven (7) to nine (9) inclusive and figures
eighteen (18) to twenty six (26) inclusive will be now described
In this machine the cutting-block Q, and the sole-former L, are arranged the
one at one cud and the other at the other end of the frame A. and each extending

page_text: in the same direction whereas in the machine of the preceding plates and s
the sole former is located directly in the rear of the cutting-block
Carriage 3 is connected to slide W, of radius bar S, through a triangular shaped
frame N, one side of which is the rack bar X which meshes with gear wheel Z³,
of handwheel Z and slides in guide way y³ of carriage 3
This rack bar X (figures 21 and 22) is secured to frame N', by headed screws o²,
and slots p7, and when the screws are loosened, it is capable of being moved on
frame N lengthwise of the guideway y³ and for so moving it a screw pin q², 18
provided
This screw pin q' has two shoulders in its length and a screw threaded portion
The shouldered portion of the screw pin q turns loosely within a suitably
constructed bearing for it of the frame N', and the screw threaded portion of said
pin enters into a screw threaded socket in one end of the rack-bar X, all so that
the axial line of the screw pin is in a line coincident with the length of such bar,
or in other words with the direction of its movement in its guide-way y
With the set screws o' which confine the rack bar X, to the triangular frame,
looking as to such confinement, the then turn of the screw-pin q', either to the
right or left, carries with it the triangular frame N', for the reason, that, the rack
bar X, cannot move because of the engagement of its teeth with the gear wheel Z*,
and thus the pivotal connection X³, of such frame, in relation to the length of
radius bar S, is correspondingly changed and there secured against movement by
tightening up the said sct-screws
This changing of the position of pivotal connection of carriage 3 with radius-
bar S, is independent in every respect, of the change of the position of the same
pivotal connection, secured, through the rack-bar X, and its gear-wheel Z³, and
attains the same result as that herein-before fully described as secured by the
arm a, Figures 1 and 15) of the hand-wheel Z
The cutter-bar 18 driven by belt 07 and pulleys P, Q, from the driving-shaft C,
and its carrying support q³ is held in position for the running of the cutter-bar y³,
by a spring-bolt r
The cutting block Q³ 18 secured by a set screw to the upper end of a vertical-
post R7, secured at its lower end, to a stationary rail S' which crosses from the
front to the rear of the frame A and is securely fastened at each end to such
frame
This carrying post R³ 18 provided with a screw-nut 87 directly under the platen Q',
and by turning this nut when the set-screw which confines the platen to the post
1s loosened, the cutting block can be adjusted in its height
The mechanism for clamping the leather to the cutting-block is as follows
T is a vertical bracket of U-shape.
-
This U-bracket has its arms, horizontal, and one above and the other below the
cutting-block and it turns by its lower arm, upon the cutting-block post R7 as a
centre, and this arm, is also arranged, to be moved up and down, upon such
post
The downward movement of the U-bracket is secured by the depression of a
treadle-lever U to which a vertical rod V7, 18 connected, that, at its upper end, 18
connected to a horizontal cross-piece t, of two parallel vertical guide-rods u
arranged to pass loosely through the cross rail 87, of the frame A, and at their
upper ends, to enter into a peripheral groove V', of the bearing portion of the
U-bracket around the cutting block post R
The downward movement of the U-bracket above described, is against a vertical
spiral spring w' secured at one end to the parts connected to the treadle-lever, as
above described, and at the other end, to the cross-rail S7 of the frame A
The upward movement of the U-bracket, 18 with the reaction of said spring W7,
and this reaction of the spring except when so desired, is prevented by catching
the treadle-lever U, in, a notch or under a shoulder of a stationary post W7, suitably
located therefore

page_text: The upward movement of the U-bracket is limited by the position of the
screw-nut a', upon the screw threaded portion of the platen-post R', between the
platen and the under arm of the bracket, and this upward movement may be
increased or deceased, within given lunits by a simple vertical adjustment of such
nut upon said platen-post.
The U-bracket, in its arms is of a sufficient length, that being swivelled to
the cutting block post R7, as above described, and moving about such post, as a
centre, it will clear the sides and ends of the cutting block and its platen or
holder
The upper arm of U-bracket and which is above the cutting block, carries a
horizontal flat clamping plate s³, of the general outline of a boot or shoe sole, but
smaller in all directions than any boot or shoe sole to be cut in the machine, when
Buch clamping-plate is used
This clamping plate is between the cutting-block and the arm of the U-bracket
which carries it, and its upper side has a transverse dovetail groove a7 and by this
groove, it is applied to a corresponding dovetail-block y' swiveled at 2', to turn
horizontally upon the upper arm of the U-bracket, and provided with a notch a³
at one end, in a position to receive a pin 6ª at one end of said groove x7
This connection of the clamping plate S, to the upper arm of the U-bracket,
allows the plate to be horizontally swung thereon, and, in addition to this attach-
ment the clamping plate has a further connection between it and the U-bracket
through a notch in a tiansverse raised edge d of the clamp-plate S¹ and an
interlocking horizontal bolt ƒ³, of the U-bracket which bolt is pivoted to the upper
end of a vertical lever g³, arranged against the outside of the vertical portion of
the U-bracket and there adapted at its lower-outside edge to engage with a notch hª,
in the cross-rail X' of the fiame A
The engagement of the lever g³ with frame A, and its bolt f with clamp-plate S
above described, is maintained by the pressure of a spring suitably arranged and
applied therefor, between it and the U-bracket, and by releasing the pressure of
this spring, the said engagement of lever g" and its bolt f both with the frame A
and the clamp-plate S is broken.
•
The engagement of the bolt f³, and clamp-plate S above described, holds the
clamp-plate against turning at its swivel upon the U-bracket and the engagement
of lever g with rail X', secures the U-bracket against swinging upon the supporting
post R', of the cutting-block Q and this latter fastening of the U-bracket 18
toward the position of the sole-former L, of the machine
The height of the U-bracket above the cutting-block, both when out and in
clamp, and the height of the cutter bar y³, and its foot piece d', when the gear
wheels o³, på, for driving and reciprocating cutting-bar are out of connection are
such relatively that the cutter-bar and foot piece, will be above and entirely clear
of the upper edge of the U-bracket.
Y' is a treadle-lever connected by a line k³ to the U-bracket.
This line k, for a portion of its length 18 made longitudinally elastic, by means
of an intermediate connected spiral spring and it passes over a guide-pulley m
of the frame.
This intermediate spring connection, between the treadle lever Y, and U-bracket,
is that a downward pressure upon the treadle, will elongate such spring 18, and
secure by its action the forward swing of the U-bracket, when the lever catch g',
that holds it is released.
The forward swing of the U-bracket is limited, by a cord n³, connecting it to
the rear side of the frame A.
This treadle lever Y', inside of its connection above described, is also connected,
by a line o³, to a vertical angular spring-lever p³, arranged to turn upon a fulcrum.
of the cross rail X', of the frame A.
This angular lever p³, has a horizontal bolt q³, pivoted to it, and this bolt 18
arranged to play through the said cross-rail ✗, in a manner to abut and press

page_text: against the lever-catch g³, which fastens the U-bracket to said cross rail, when said
angular lever, through the treadle V', is turned against its spring and thus to press
such lever catch, in the proper direction to release it from its hold of the
U-bracket, which then by the reaction of the spring 1, before described, as forming
a part of the connection between it and the treadle lever V', swings towards the
front of the machine.
The running and operation of the machine shown particularly in Figures 18 to 26
inclusive plates seven (7) to nine (9) inclusive, differs essentially from the running
and operation of the machine, shown in the figures of the preceding plates, only in
respect to the operation of the clamping mechanism for the leather upon the cutting
block
In plates seven (7) to nine (9) inclusive the leather to be cut is clamped upon the
cutting block Q, by depressing the treadle U', and catching it on the post W7, and
as the cutting proceeds, the U-bracket T' is manipulated by the hand and through
the treadle Y, and mechanism connecting same to said bracket so as to enable the
cutter bar y³, to make a complete circuit of the cutting block in accordance with the
travel of the tracer around the sole pattern.
Figure 20 plate 9, is more particularly a diagram illustrative of the position of the
U-bracket T, at the beginning and at the end of the cutting operation, it being
swung toward the front of the machine in the beginning and into its position
coincident with the longer axis of the upper clamp a², after the cutter-bar y has
passed sufficiently around therefor and then bolted and secured as has been
described
.
The fastening bolt f³, of the U-bracket T', is released by depressing the
tieadle Y', on which the U-bracket is thrown forward, but before such manipulation
the cutter bar y³, must be thrown up from the cutting block
In the operation herein described, of grading as to the length the perpendicular
distance between the pivotal connections a², t2 which in that movement, corresponds
to the pivotal connections y*, m³, in the grading operations as to the width, is the
same and equal at all parts and for the whole length of such movement and as
before stated in view of these facts an exact and direct proportionate reduction or
increase in length was given to the movement of the cutter bar in that direction in
relation to the length of the sole-former
To obtain as to the width, a result similar to that described for the length, the
connection which has been shown and described, is changed in this respect, that the
pivotal point m³, of connection of the radius-bar C, at the rod H, is so made, that
it will always be at the same distance perpendicularly from the transverse line of
travel of pivotal connection y, of a radius bar C, to carriage 4 and the radius-
bai C, will have a movement lengthwise over it
This arrangement of connection is particularly shown in figures 27, 28, 29 and 30,
of the diawings plate 9
In this connection between radius-bar C and frame I, the plate-slide B³, of
cainage 3, 18 provided on its upper side with a longitudinal dovetail-block A*, and
with a dovetail-bar B, adapted to slide over and along the length of the block A°,
and by a set screw as to be set against further movement thereon, when so desired
The bar B³, crosses the plate-slide B³, at right angles to its length and its edges
along their length are dovetailed and they carry a correspondingly dovetail-slide-
block Go, concentrically swivelled by a vertical pivot g³, to the eye-stud c³, of the
horizontal rod H³, to the frame I, before referred to and to which as before
described, the radius-bar C, was connected
This swivel-pin go, between the slide-block C, and the eye-stud co, passes loosely
and concentrically through a straight-sided washer do which fits loosely within the
slot running lengthwise of the radius bai C*
This constitutes the connection, and obvious'y the slide of the bar B³, upon the
block A, in the direction of the length of the slide-plate B', carries with it the
swivel or pivotal connection q³, of it to radius-bar C' along the rod H³, of frame I³,

page_text: and thus the perpendicular distance between such pivotal connection g³, and the
pivotal connection y', of the same radius-bar C4, to carriage 4 relative to the line
of the travel of such carriage 4, together with carriages 3 and 2, across the line of
travel of carriage 1, upon carriage 2, can be made greater or lesser, and when so
made secured against movement by tightening up the set-screw a³
With the pivotal connections y', q, of radius-bar C4, to carriage 4, and to frame 1',
thus adjusted and set, then in any and all movements of carriages 3 and 4 across
the line of travel of carriage 1, the same relative perpendicular distances are
always maintained between the said pivotal connections, thus causing in all
movements of carriage upon carriage 3, and of both these carriages together
across the line of travel of carriage 1, and of the cutter-bar in conjunction therewith
a movement of the cutter-bar, which as to any and all portions, or the whole of its
length and whether its whole length be equal to or greater or lesser than the
shorter axis or width of the sole former L, 18, in exact and direct proportion to the
movement of carriage 2, in the direction of the width of the sole-former
Again Figures 27 to 30 inclusive plate 9 illustrate another forin and arrangement
of mechanism for securing adjustments similar to those described for the hand-
wheel L, and handle-lever A' This mechanism is as follows
-
D' 18 a horizontal screw-threaded shaft, arranged in a line with and above the
plate-slide B at the left hand end thereof
This screw-threaded shaft D³ turns loosely in an upright of the plate-slide B' and
18 confined against lengthwise movement in such upright by its shoulders, at each
side of the upright
At one end the shaft D' bears against a raised projection F, of the plate-slide Bª,
and at the other end, it carries a bevel gear-wheel G with which meshes a similar
bevel gear-wheel H of a horizontal stud I, arranged to turn in bearings of the
upright Es, before referred to and provided with a crank-handle J³, for convenience
in turning it
This screw threaded shaft D³, between its two ends, screws into a screw-threaded
nut K³, which projects downward through a slot running lengthwise of the plate-
slide B, and below, it is entered by another horizontal screw threaded shaft L'
This lower screw threaded shaft Lº, runs, in a parallel line with the upper screw
threaded shaft D³, and at the right hand end of the plate-slide B³, it turns in a
stationary upright M³, of carriage 3, wherein, it is held against a lateral movement
by the shoulders of the shaft, at each side of said upright and outside of and beyond
said upright it carries a bevel gear wheel No, and with this gear-wheel N, meshes a
similar bevel gear wheel 0³ of a horizontal shaft P5 which runs at right angles to
the length of the lower screw-threaded shaft L³, and is arranged to turn in the
fixed upright R³, of carriage 3
This shaft Ps, carries a small gear-wheel S³, which meshes into a larger gear
wheel T³, having a crank-handle Ū³, for convenience in turning it and this wheel T",
in turn meshes into a small gear-wheel V, of a screw-threaded shaft W, which 18
supported in the fixed upright R³, and by shoulders is confined against escape
lengthwise therefrom, and is in a line with the movement of the triangular frame
piece N', along the guide-way Y", of carriage 3
This screw-threaded shaft W, enters and screws into a screw-threaded socket of
said frame piece N'
A turn of the handle J³, at the left hand end of the plate-slide B³, to the right
or left, moves the slide-plate, in the same direction, and thus the position of the
pivotal connection ³, of radius-bar C, to such plate slide, or in other words to
carriage 3, is changed relative to pivotal connection y, of such plate slide B³, to
carriage 4, the same as is done with the handle-lever A2, as before described
A turn of the handle Us, of gear wheel T, to right or left, through the train of
gearing and mechanism connected to the triangular frame N7, on the one side, and
on the other side to the plate-slide, B³, as has been described, enables the pivotal
connection a³, of carriage 3, to radius-bar S, and of pivotal connection y', of

page_text: carriage 4, to radius-bar 0%, to be both changed and adjusted in position, the same
as herein described in the turning of the hand-wheel Z
To gauge either or both of these adjustments, pointers a 6º, and graduated
scales d, f, are suitably applied as shown which pointers and graduated scales are
in substance the same as the two series of graduations of the hand-wheel Z the
pointer e, and the handle lever A³ hereinbefore particularly described
