Improvements in Pantographs, chiefly designed for Forming Boot
and Shoe Patterns.
1, HENRY HARRIS LAKE of the firmn of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings in the County of Middlesex, do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This invention relates to pantographs and has for its object the adaptation of
the pantograph to use in outlining and proportioning boot and shoe patterns and
drawing the same on paper, or cutting the same from paper or other suitable
material.
In the manufacture of boots and shoes a great number of sizes and styles have to
be made to meet all requirements of the various purchasers, and in order to with-
stand the sharp competition in the business, it is necessary that economy be
exercised in the cutting of the stock and therefore patterns have to be made for
cach size and style of upper.
A very important item in the production of these patterns is the proper outlining
and proportioning of all the sizes of a given style from a single pattern, and this,.
when done by hand by an expert draughtsman is an expensive operation.
To obviate the necessity of employing such skilled labor to do this work and to
render it practical for any intelligent workman to produce his own patterns or if
desired to cut his own uppers, all correctly proportioned and scaled, up or down,
consists in certain
from a single pattern, is the object of my present invention and
novel features of construction, arrangement and combination of parts which will
be readily understood by reference to the description of the drawings in which

In the drawings A is a rectangular table made preferably of wood which may be
supported in any suitable manner at a convenient height for operation; B is a
metal disc or plate having cut through it an open slot extending about three-fourths
of the distance across it a little to one side of its centre, the side wall of said slot
being provided with inwardly projecting lips a a to which is fitted so as to be
movable thereon the three armed or T-shaped bar or plate B', to which is pivoted
at a the immer end of the lever b, fulcrumed upon the pin set in the disc B.
The disc B is firmly secured to the table A and has formed in its upper surface
a plurality of grooves cc' and c² arranged at right angles to the line of movement
of the bar B, and the lever has pivoted thereto between its fulcrum pin and the
bar the forked ends of the handle provided with the slot in which is
adjustably secured the pin the lower end of which engages one of the slots c c¹
or e when the free end of the handle 2 is depressed.
The table A also has firmly secured thereto the supporting bars A' and A' at the
rear edge and right hand end respectively, and has secured to its upper surface, one
near each end thereof, the standards C, the upper ends of which are connected
together by the rod C, in the under side of which is formed the longitudinal
groove a² said rod C' having mounted thereon so as to be adjustable cudwise
thereof the sleeve C2, which is provided with the spline a³ to fit the groove a²
and the set screw d to clamp said sleeve in position on said rod C
The sleeve C has formed therein a socket or bearing at right. angles to, but
below the rod C in which is fitted so as to be movable endwise therein the rod C³
having secured to its front end the bar C, which has formed therein the slots d'
in which are adjustably secured by the nuts e³ the clamping bolts ee and the pendent
hubs ee to which the metal pattern C is secured by means of the nuts e² e² as
shown in Figures 1, 2, 15 and 16.
The three armed bar B' has formed in its upper surface the rectangular groove c³
and the inverted T-shaped groove e arranged at right angles to the groove c³, said
groove having fitted thereto so as to be movable end wise therein, the plate B² to
which is pivoted by the common fulcrum pin d² the bars D and E.
The bar D has its main body from near the fulcrum pin d to its right hand end
made L-shaped and has formed in its front side the shallow longitudinal groove f
as shown in Figures 9 and 12.
The horizontal web portion of the bar D extends beyond the fulcrum pin d
towards the left of Figures 1 and 8, and has formed therein the longitudinal slot f
in which is adjustably secured the stud g upon the lower end of which is mounted
the roll which fits into the groove c³ in the bar B' as shown in Figures 9 and 10.
The study also carries the rectangular plate one edge of which serves as an
index to assist in the proper adjustment of the stud in said slot, the bar D having
formed thereon a series of graduations as shown in Figure 8.
༡
The bar D is made of sufficient length to rest, at its free right hand end, upon
the bar A by which and the bar A it is maintained at a suitable distance above
and parallel to the table A as shown in Figure 1.
The bar D has an offset or bend in it, near the fulcrum pin d², so that the pencil
holding sockets to be hereinafter referred to may extend below said bar and at
the same time be in line with the centres of the fulcrum pins d2 and g as shown in
Figure 1.
.

page_text: The bar Eis T-shaped in cross section the central rib being upon its under side
as shown in Figure 4 and rests in a notch d³ in the radius arm B' mounted upon
and movable about the vertical stud B' set in the plate B as shown in Figures 1, 2, 4,
and 8.
Fis a rectangular bar arranged to rest upon the bars D and E in a position at a
variable angle thereto and adjustably connected thereto by means of the two
slides E and E fitted to and clamped upon said bars E and F respectively and
pivoted together by a suitable pin as shown in Figures 1, 3, 4, and 5.
The front end of the bar F is connected by the pencil and knike socket / to
the slide H fitted to and movable endwise of the bar D, as shown in Figures 1, 2,
3, 4 and 12.
The bar F has pivoted to its under side a series of bars
which rest a series of socket carrying bars G1, G2, G3, G4, G³,
G", G, G, G, G, and G, each of which is pivoted to,
supporting bars 1, 1, 12, or 13 and the front end of the bar
pencil socket to the slide H as shown in Figure 4.
I, 11, 12 and 13 upon
G, G, G³, Gº, G",
at least two of the
is connected by its
The bars E and F are graduated so as to facilitate the correct adjustment of the
slides E and E² thereon.
J and are two standards mounted upon the bars I and 12 above the
bars GG and G and having secured to their upper ends the arm K by means
of the thumb screws j j¹ in such a manner that it may be adjusted in a direction
parallel to a line drawn through the centre of the several pencil or knife holding
sockets h, said arm having a series of holes formed therein to receive the shanks
of the screws and as shown in dotted lines in Figure 3, the upper end of
said standards J and J¹ having formed therein a corresponding number of
threaded holes to receive the threaded ends of said screw shanks.
The arm K has set in its front end the tubular stud k upon which is mounted
the sleeve provided with a hub or shank k upon which is secured by suitable
outs the U-shaped swivel to which is pivoted the handle by which the
machine is manipulated.
The stud has mounted therein the spindle to the upper end of which is secured
the crank having the crank pin upon which is mounted the truck having
formed therein a peripheral groove the bottom of which is directly over the centre
of the spindle which in turn is directly over the centre of one of the pencil
sockets, or in the vertical plane cutting through the series of pencil sockets.
In operating the instrument the truck is placed with its grooved periphery in
contact with the edge of the pattern C and kept in contact therewith while it is
passed entirely around its perimeter.
L is a plate of glass resting upon the table A between the disc B and the bar A*
and secured in position in any convenient manner, and M M are two clamping bars
for holding the paper or leather in position on said glass, said bars being provided
at each end with a downwardly projecting hook M' which engages with the lifting
bars N secured one to the front edge and one to the rear edge of the table A by
means of the screw studs p which pass through oblique slots p' cut through said
bars N and screw into the table A as shown in Figures 1 and 2.
Each of the bars N has formed in its upper edge, near one end thereof, a series
of rack teeth arranged in a plane parallel to the centre lines of the slots p' with
each of which the teeth of a segment of a gear mounted upon the rocker shaft O
mounted in bearings on the table A, engage as shown in Figure 20.
The shaft O has secured upon one end thereof the lever P by which it may be
rotated to raise or lower, the bars M M.
In one of the sockets is placed a pencil or knife holding spindle to the upper
end of which is pivoted one end of the lever r' fulcrumed on the stand g, which has
a forked arm to embrace the peripheral grooves in the socket tube h, with an
outwardly projecting finger receiving arm and the latch catch q².
The lever projects outward beyond its pivotal connection to said stand 9, and
has pivoted thereto the latch lever q³ the outer arm of which is forced upward by

page_text: the spring g' to cause its inner end to engage with the catch when the outer arm
of the lever is depressed to raise the pencil or knife from contact with the paper,
or the glass plate, against the tension of the spring tall as shown in Figures 13
and 14.
The pencil is mounted in a tubular socket constructed and arranged to clamp the
pencil lead in the same manner as the well known tubular drawing pencil and is
shown in clevation in Figure 13.
In Figure 14 the knife for cutting patterns is shown.
The spindler has a cylindrical hole drilled in its lower end in which is inserted
the shank u of the knife in such a manner that it is free to revolve therein but
will not fall out when the spindle is raised as shown in Figure 14.
The knife has an inclined cutting edge so formed that the end of the knife which
rests upon the glass, when in action, is at one side of the axial line of the shank of
said knife so that it will automatically maintain a position with its cutting edge to
the front, in whatever direction it may be moved.
The pattern shown in Figure 1 and marked C³ is for a boot quarter, but in order
to adapt the machine to draw or cut patterns of long legged boot fronts or shoe
vamps a modification of the supports for the patterns is necessary as follows:-
The pattern Cs may be readily supported by two pendent attachments to the
slotted bar C but if a long legged boot front pattern or a shoe vamp pattern is to
be drawn or cut three pendent supports for the pattern are necessary and the
.pattern must be arranged with its centre line extending in the direction of its
greatest dimension parallel to the rod C¹ as shown in Figure 18. To this end the
rod C is removed from the bearing in the lower part of the sleeve C' and the
rod R having the sleeve like hub Rat one end is fitted in said bearing, and
the rod C3 is inserted in the sleeve R, and has adjustably secured thereon the
split sleeve R which is secured in position by the clamping bolt e and nut and
the vamp pattern S' or the boot leg pattern S shown in dotted lines in Figure 18 is.
secured to the pendent supports ee and R as shown in Figures 2 and 18.
The rods C and R' are prevented from turning about, their axes in their
bearings by a set screw as T screwed into their bearings and entering a longitudinal
groove in said rods as shown in Figures 15 and 16.
The operation of my invention is as follows
The several parts of the apparatus being in the position shown in Figures 1 and 2
the first operation is to move the free end of the lever P upward into a horizontal
position so as to move the bars N obliquely upward and thereby lift the bars M
from contact with the glass plate L, when the paper or other material to be drawn
upon or cut is placed in position on the glass plate and beneath the bars M M and
then the lever P is returned to the position shown in Figure 2 when the bars M M
will be forced down upon the material to be acted upon so as to hold it firmly in
position.
If the pattern is to be drawn upon paper the pencil and its holder P shown in
Figure 13 is inserted in the tubular socket h appropriate to the size of pattern that
it is to draw, and the stand q has its forked arm fitted to the grooves of said
socket as shown in Figure 13.
If the pattern is to be cut from paper or other material the knife and its
holder 'r, stand 9 and attachments are applied to the same socket in place of the
pencil.
The pattern C³ S or S' is adjusted to the proper position above the socket
carrying bars and the slides E' and E' are adjusted on the bars E and F to the
graduation appropriate to the size of pattern on the machine i.e. at 30 if
No. 5 pattern is used or 29 if No. 4 pattern is used as in the drawing.
The truck is then brought into position with its periphery at the bottom of
its groove, in contact with the pattern C³ at a suitable point as v. The lever gis
then disengaged from the catch and the tension of the spring t will cause the
pencil or knife to be brought into contact with the material to be acted upon.
The operator then moves the truck 13 around the pattern C³ by means of the
1

page_text: handle, in the direction indicated by the arrow on Figure 1 when the pencil or
knife, if set in the tubular socket fitted in the bar G" directly beneath the truck
carrying arm K will describe on or cut from the paper or other material an exact
duplicate in outline of the pattern on the machine.
To draw or cut patterns of larger or smaller sizes than the pattern on the
machine the pencil or knife is placed in the socket corresponding to the number of
the boot for which the pattern is intended. If this were done with the slide
plate 12 made fast or immovable and the fulcrum ping removed so that the bar E
and the pencil carrying bar would be moved about a fixed fulcrum like the
ordinary pantograph each of the different sizes drawn would be reduced or increased
in size in a true mathematical proportion in all directions, but as the patterns for
the smaller sizes do not diminish in size in the same proportion throughout, or in
other words, as the dimension of the pattern in the direction of the height of the
hoot or shoe requires to be reduced less in proportion than in the direction of the
length of the shoe, it becomes necessary to make some provision in the machine for
giving this varying proportion.
This provision consists in the employment of the sliding plate B connected by
the common fulcrum pin d to the bars D and E, the slotted extension of the
bar D, the fulcrum ping, and the groove in the plate B¹.
When the plate B is free to move in the groove so that the bar D will move
about the fulcrum ping a pattern will be drawn or cut by moving the truck
about the pattern C that is increased or reduced in a certain proportion in the
direction of the length of the rod C and in a certain other proportion in a
direction at right angles to said rod, the amount of the variation of said two
proportions being determined by the distance from the fulcrum pin dat which the
fulcrum pin is clamped to the bar D.
In certain cases it is desirable to make the leg portion of the pattern of a greater
proportionate dimension in the direction of the length of the boot or shoe than the
foot, independently of the variation in the proportions, produced by the movements
of the members of the pantograph about the two fulcrum pins dandy and to this
end the lever 2 pin b, and grooves and c² are employed as follows:
--
When it is desired to draw or cut a pattern of a smaller size than the pattern
on the machine but having a full leg in proportion to the height without increasing
the proportion of the length of the foot the lever 662 may be in the position shown
in the drawings with the pin in the groove c' or it may be adjusted to the left of
Figure 1 with the pin in the groove c.
The pencil or knife is fitted to the paper socket h, the wheel is moved into
contact with the pattern C say at and moved around the pattern in contact
therewith until the point is reached, when the lever is moved about its pivot,
by first raising the handle and the pin is made to engage the groove c² which
operation causes a movement of the plate B' with the bars D E F and the other
socket carrying bars a certain distance towards the left of Figure 1, thus adding
an equal amount to the dimension of the leg in that direction.
The operator then moves the truck around the pattern in the same direction
until the point is reached when the lever is moved back to its original
position and then the truck is moved to the starting point to complete the
pattern.
The amount of variation made by the manipulation of the lever b² may be
varied by moving it so as to transfer the pin 6 from one groove to the next, or
from the groove c to the groove, or by moving the pin nearer to or farther
from the fulcrum pin so that the angular movement of said lever necessary to
transfer the pin from one groove to another will be increased or diminished
recording to the requirements of the case.
:
The machine as illustrated in the drawings is supplied with a No. 4 pattern and
the slides E and E" are adjusted on the bars E and F to the graduation
numbered 29 which is the proper number if the patterns to be drawn or cut are
graded according to the English or American scale, where the variation between

page_text: the sizes is one third of an inch, but if the patterns to be drawn or cut are to be
graded according to the French scale in which the difference between the sizes is
only about one-fourth of an inch the slides E1 and E2 should be moved on the
bars E and F until they coincide with the graduations numbered 40, when if the
same No 4 pattern he properly adjusted to a position centrally over the series of
pencil or knife carrying bars, a series of patterns may be drawn or cut proportioned
according to the Erench scale.
If the pattern to be used on the machine should for any reason be larger or
smaller than No. 4 the slides E and E2 would have to be moved on the bars E
and F as many divisions above or below where they are now set, if English sizes are
to be proportioned, or above or below No. 40 if French sizes are to be drawn or cut,
as the pattern on the machine is sizes larger or smaller than No. 4.
It must be understood that the graduations on the bars E and Fare at a distance
apart equal to the distance from the centre of one pencil carrying bar to the centre
of the next pencil carrying bar and that said graduations are so arranged thereon
and numbered that the graduations coinciding with the ends of the slides E'
and E shall indicate the number of divisions on the bars E and F between the
pivotal connection of said slides and the centre of the fulcrum pin and the
centre of the pencil socket in the bar F respectively.
This adjustable pivoting of the bars E and F, whereby the whole series of pencil
carrying bars may be moved bodily to a greater or less distance from the fulcrum
pin without changing their relations to each other thus rendering it possible to
adapt the machine to work from different sized original patterns in grading patterns
'to the same scale or to grade patterns to different scales from the same pattern, is
a very important feature of my invention, and as far as my knowledge extends is
entirely new.
+
The inachine may be adapted to draw or cut patterns for half sizes by adjusting
the pins and in the proper holes in the bar K and in the studs J and J.
The studs and J₁ are set centrally over the bar G" and in the upper end of
cach is formed three holes u³ u and us the hole 3 being in the centre and directly
above the centre of the bar G the hole being directly over the centre of the
space between the bars G and G" and the hole being directly over the centre
of the space between the bars G and G. The bar K has formed therein two
series of three holes we¹ and w² arranged as shown in Figure 17.
When the machine is adjusted as shown on the drawings the pins j and jare
passed through the holes w into the holes in the studs but if it is desired to draw
or cut half sizes said pins are passed through the holes in the bar K and into
the holes in the studs or through the hole w in the bar or arm K and into the
hole in the studs J and J. It will be observed by referring to Figure 17 that
the holes in the arm K are in the longitudinal central line of said arm and that the
holes in the studs J and J are arranged in rows at right angles to said centre line
of the arm K, and that in making the adjustments of said arm as described the
axis of the crank shaft in the end of the arm K will be moved a distance equal to
'one half the distance between the centres of two contiguous pencil sockets and in
the vertical plane which cuts through the row, of said sockets.
The amount of the variation in the proportion of the width of the boot leg
pattern to the height of the same may be varied by adjusting the fulcrum pin g
to a greater or less distance from the pin independent of the manipulation of the
lever b 6.
