* COMPLETE SPECIFICATION,
Improvements in Shaping or Treeing Forms for Boots and Shoes.
I, GEORGE MARTIN COBURN, of 22 High Street, Boston, in the County of Suffolk,
and State of Massachusetts, United States of America, 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:
-
So far as I am aware it is now customary in shaping button boots and shoes
to introduce a follower into the unbuttoned boot, or to draw the unbuttoned boot
onto a form, to give shape to the fore-part, and after cleaning or in any other way
treating the boot to remove the follower or withdraw it from the form, and then
button the boot.
Neither of these processes gives shape to the ankle and top portions of the boot
or shoe.
The boot, however, may be buttoned after it has been drawn onto the form, and
then shaped, and at such time the ankle and top portions will be shaped, but it
must be unbuttoned before it can be withdrawn from the form, and afterwards
buttoned for shipment, and such shape as may be given to it by so buttoning the
boot while on the form and then shaping it, is practically destroyed by unbuttoning
the boot, then withdrawing it from the form and finally buttoning it again.
The result is that in such case much time is consumed in buttoning and unbutton-
ing the boots or shoes, and the ankle and top portions are not then shaped.
This invention has for its object to so construct a shoe shaping or treeing form,
or shaping machine, that a button boot, while buttoned, may be drawn onto the
form, and held with its upper drawn taut from top to toe, and after it has been
shaped and cleaned, or treated in any other desirable way, it may be withdrawn
from said form without being unbuttoned, thereby greatly facilitating the work
and also enabling the shape which may be given to its ankle and top portions to
be retained.
In order that a buttoned boot may be drawn onto and off a form, the circum-
ferential measurements of all parts of said form below the ankle must be reducible
to the size of the ankle or most contracted part of the top of the boot or shoe, and
my invention consists in so constructing a shoe shaping or treeing form that all
of its circumferential measurements below the ankle are reducible to the ankle
measurement of the boot or shoe.
The shoe shaping or treeing form comprehending this invention comprises essen-
tially a back part and a fore-part, the latter being detachable in order that fore-
parts of different shapes and sizes for different shapes and sizes of boots and shoes
may be employed, and as the ball and ankle measurements of a boot or shoe are
usually substantially equal, I find that by reducing the instep measurement of the
fore-part of the form to the ankle measurement of the shoe, and also by reducing the
heel measurement of the form to said ankle measurement of the shoe, that the cir
cumferential measurements of all parts of said form below the ankle will be no
greater than said ankle measurement of the shoe.
By the term "ankle measurement of the shoe," I mean the ankle measurement
of a button boot or other boot or shoe, as for instance, a lace shoe or Congress boot,

page_text: having its ankle and ball measurements substantially equal, the ankle measure-
ment being taken in the case of a button boot with the boot buttoned, and in
the case of a lace shoe with the shoe laced, or in the case of a Congress boot with
its gores unstretched.
The instep measurements of the fore-part may be reduced to the ankle measure-
ment of the shoe by cutting away the shank of said fore-part to a considerable
extent, leaving a gap at such point, or by providing a movable or sliding shank-
piece, and the heel measurement of the form may be reduced to the ankle measure-
ment of the shoe by making the parts thereof movable one with relation to the
other, that is to say, the two essential parts of the form may be arranged to slide
in and out one with relation to the other, thereby extending or lengthening the
form or tree, and said parts also may be moved toward and from each other a
certain extent, so that said parts have two movements one with relation to the other,
viz a movement toward and from each other, and a movement in and out and
the reduced heel measurement of the form above referred to is or may be taken
with the parts closed together and drawn out.
The reduction of the instep measurement of the fore-part and of the heel measure-
ment of the form to the ankle measurement of the shoe, is necessary as before
stated in order that the boot or shoe may be drawn onto and off the form, but it is
obvious that such measurements may be not only reduced to the ankle measurement
of the shoe, but preferably will be still further reduced for greater ease in drawing
the boot or shoe onto and off the form, and hence I desire it to be understood that
such further reduction in the instep measurement of the fore-part and heel measure-
ment of the form comes within the spirit and scope of this invention.
For separating the essential parts of the form or tree an expanding device of
any usual construction may be employed.
The fore-parts of the form may be attached to or connected with independent
detachable shin pieces, and several different sizes of shin pieces may be used to
which the fore-parts are graduated; and furthermore the back part of the form
may have an oblique sliding heel or heel piece to facilitate withdrawal of the boot.

ing my invention.

page_text: The central support or frame of the shoe shaping or treeing form or tree consists
of a frame bar a, of a width corresponding to the width of the form or tree, and
extending from end to end of said form or tree, and having at its upper or knee-
end a circular flange a¹, and an ear or equivalent a² formed adjacent to it, and a
cylindrical hub as which enters and is adapted to revolve in a bearing box at
stationarily supported on a bench or other suitable frame.
On the underside of the centre frame or support a the back. leg portion b is
mounted, which as herein shown, constitutes the back part of the form, and said
part bis hollowed out or recessed, and has at its upper or knee-end two ears which
receive between them the ear a² of the frame-bar a, and has at its lower or opposite
end a heel piece c.
Yet said back part of the form may be constructed in many different ways, all of
which would present a suitable back part for the form, and hence would be included
in this invention.
A pin b projects from the ear a³ which passes through a hole at the upper end
of the back leg part b, and thence through a plate d, one end of which bears upon
or against the back leg portion, and the other end of which has a pin which
enters a hole formed in the circular flange a¹.
A strong spiral spring & encircles the pin b¹ and presses against the plate d,
and a thumb nut d³ is turned on the pin 61 which acts upon the spring.
By means of this device for connecting the upper or knee-end of the back leg
portion with the central or main frame it will be seen that said back leg
portion b is bodily movable toward and from said central portion a to a certain
extent.
The heel piece c is cut off obliquely and adapted to slide obliquely with relation
to the part to which it is connected, and it has a dove-tailed projection which enters
and slides freely in a groove formed to receive it in the heel-end of the back leg
part b.
The obliquely sliding heel piece c has a pin c which enters a slot formed in the
part to which it is connected, which limits the sliding motion of said heel piece.
When the parts of the form or tree are separated it is necessary, or at least very
desirable, that the sliding heel piece should be locked, in position, and when the
parts close together that said heel piece shall be free to slide in order that the
advantages sought for may be gained.
Therefore an automatic locking device is provided which consists of a detent,
pivoted at in a suitable recess formed in the heel-end of the back leg part b,
which is adapted to enter a hole formed in the sliding heel piece c,, when said heel
piece is in its normal position, and the hole therein is thus brought into position
beneath the detent.
The pivoted detent has a projection or extension which is acted upon by a
spring, the tendency of which is to press the detent into engagement with the
sliding heel-piece, when it is permitted to act.
A projection or lug co, see dotted lines Figure 1, is arranged on the underside of
the central portion or frame bar, just above the extension of the detent, and
when the parts of the form or tree close together this lug engages said extension
and by depressing it, raises the detent out of engagement with the sliding heel-
piece.
Thus this locking device is automatic in its action to both lock and unlock the
sliding heel piece.
The upper face of the frame bar a is formed with a T-groove which receives
a T-shaped slide e, and the fore-part el is formed to fit the fore-part of the boot or
shoe, but is cut away at its shank adjacent the heel to diminish the measurement
at the instep, making it equal or less than the ankle measurement of the boot or
shoe which is adapted to be placed upon it, and said fore-part is connected by any
suitable fastening to a shin piece f, which is detachably connected with the slide e
by means of a spring actuated pin f¹ or other suitable fastening at one end and a
headed stud eat the other end.

page_text: The reduced instep measurement of said fore-part is represented by
line 10.
The expanding device for the parts of the tree is herein shown as consisting of
a screw-rod g having thereon two wedges gl, g¹, which may be adjusted along said
rod, said wedges entering and sliding in a groove formed in the underside of the
central portion à of the form and bearing upon rolls journalled in the back leg
portion b.
This screw-rod g passes through a hole made in the knee-end of the frame-bar a,
and is attached to a rod g³, swivelled to a block g³, having its bearings in the
rotating hub a³ of the tree.
The block g³ is connected to a sliding block g having its bearings in a suitable
stationarily supported frame, which block has at its rear end a hook 95 to which
a cord is attached which passes over a suitable pulley, and thence to a treadle by
means of which the parts are drawn rearwardly and the form or tree expanded.
A spring 950 is provided for retracting the parts.
The block is provided with a series of notches go which are engaged by a spring-
pressed pawl to lock the expanding device in whatever position it may be set, said
pawl having a hand engaging portion by means of which it is operated to release
the expanding device.
In Figure 1, the form is shown expanded, and when it is desired to withdraw the
boot or shoe from the form the expanding device g, g¹, is released, which moves for-
ward and allows the back b to approach the frame a and occupy a position against
and in parallelism with said frame, and then by taking hold of the boot or shoe
and pulling it off the form the fore-part e¹ and slide e to which it is attached, will
be drawn out quite a distance sliding on the frame a. In other figures of the
drawing showing modifications the parts are collapsed and drawn out, from which
it will be seen how the boot or shoe is withdrawn from the form.
So far as this invention is concerned any other suitable expanding device may
be employed.
By referring to Figure 1 of the drawing 12 represents the ball measurement of
the fore-part, and in ordinary boots and shoes this measurement is substantially
equal to the ankle measurement of the boot or shoe which is adapted to be placed
on said fore-part, and 10, as before stated, is the reduced instep measurement of
said fore-part, and with a fore-part so constructed or formed, all of its measurements
will be equal or less than the ankle measurement of the shoe; yet I desire to
include within the spirit and scope of this invention any other form or construc-
tion of fore-part, whereby its instep measurement is no greater than its ball measure-
ment and consequently no greater than the ankle measurement of the shoe.
It will also be observed that the heel measurement of the form represented by
dotted line 15 is reducible to the ankle measurement of the boot or shoe, by closing
the parts of said form together and drawing out the fore-part; but I do not desire
to limit my invention to thus reducing the heel measurement of the form, and
furthermore I desire it to be understood that I include within the spirit and scope
of this invention any construction or arrangement of parts of the form whereby all
of its circumferential measurements below the ankle are reducible to the ankle
measurement of the boot or shoe.
The form or shaping machine herein described is especially designed for button
boots or shoes, but it is obvious that it is of equal utility in shaping lace boots and
shoes, which are laced up in order that the ankle and top portion may be shaped, and
also in shaping Congress boots and shoes, where it is desirable not to stretch the
gores.
The form shown in Figures 5 to 8 which also comprehends this invention, con-
sists essentially of a back part h having a heel h¹, a front leg portion i having an
extension ¹, see dotted lines Figure 5, contained in a recess in the back part h, a
support rigidly secured to the front leg portion i, a slide fitted to slide freely
in and out in a groove formed in the part j, a shin piece detachably connected
with said slide, and a fore-part detachably connected with said shin piece 7³.

page_text: The back leg portion h of the form shown in Figure 5 is bodily movable and has
a pin 6 at each side of it which is engaged by the free ends of springs 7 secured by
screws 20 or otherwise to the opposite sides of the front leg portion i.
These springs 7 hold the back leg portion / up in position, yet permit it to be
moyed bodily away from the front leg portion i.
A guide pin 8 projects from the front leg portion on which said back leg
portion is adapted to move bodily toward and from the part i.
The expanding device herein shown consists of a rod kadapted to be drawn out
to expand the form, having thereon two wedges k¹, , see dotted lines Figure 5, one
of which, as k¹, acts upon a pin or roll at the forward end of the form, and the
other of which as acts upon a spring pressed or yielding device at the other
end of the form.
The yielding device consists of an arm ³ pivoted at to the back leg part h and
extending rearwardly and bearing a roll, or it may be a projection or other engaging
face which lies in the path of movement of the wedge
The rear end of the pivoted arm has a hole through it which receives the
pin 8 and said rear end of the arm bears upon a spring which encircles said pin 8,
said spring entering a recess formed in a nut which is screwed into a hole in the
back leg part h, and thus supports said spring, and said nut has a hole through
it for the pin 8 so that said back part. h may move freely.
As the expanding rod k is withdrawn the wedges k³, ³, will act to bodily move
the back leg portion h outward, and the spring pressed arm will at such time
yield.
By turning the nut, the spring-pressed arm ³ may be adjusted to thereby
enable the back leg part to be moved more or less as desired.
The particular means herein shown for moving the back part h bodily in and
out possesses some advantages, but so far as the broad features of this invention
are concerned they may be materially altered, or said back-part h may be moved
in any other way.
The fore-part comprises an upper part m and a lower part m³, the former com-
prehending the instep portion and the latter comprehending or including the toe;
ball and shank portions.
Such fore-part may be made by forming a block of proper shape, and then cutting
it in two parts on or about the line 2.
This line of severance may be more or less curved if desired.
The two parts m, m³, of the fore-part are or may be connected together in such
manner that the lower part is adapted to slide along the bottom of or with relation
to the upper part, and herein such sliding connection is shown as a dove-tailed
rib 4 secured to the meeting or upper face of the lower part, and a corresponding
groove, see dotted lines, formed on the meeting or lower face of the upper part,
but any other form or construction of sliding connection may be employed.
A socket 9 is provided at the forward end of the upper part and a spring pin 10
is provided at the rear end of the lower part which enters said socket when the
lower part is withdrawn to its fullest extent.
When the fore-part m, m² is drawn out with relation to the back-part as shown in
Figure 6, it will be seen that the heel measurement of the form is materially
reduced, being equal or less than the ankle measurement of the shoe, and when
the lower part or shank piece m¹ is drawn out with relation to the upper part m,
it will be seen that the instep measurement of the fore-part is very materially
reduced being equal or less than the ankle measurement of the shoe.
The boot or shoe to be shaped or treed may be drawn onto this form while
buttoned, and after it has been operated upon it can be easily withdrawn from
said form without unbuttoning, by drawing out the slide 1 with relation to the
heel as shown in Figure 6, and then drawing out the shank piece or lower part m¹
of the fore-part with relation to the upper part j as shown in Figure 7.
I do not desire to limit my invention to any particular way of forming a
movable shank portion on the fore-part, to reduce the instep measurement thereof

page_text: to the ankle measurement of the boot or shoe, but the way herein shown is easy
to construct and is efficient, and the gap produced by cutting away the shank of
the fore-part, as represented in Figure 1, is completely filled.
In the above construction it will be observed that the fore-part slides in and
out with relation to the back-part, but it is immaterial in a broad sense, which part
moves relatively to the other, and therefore I desire it to be understood that so far
as this invention is concerned I deem either an equivalent construction of the
other.
The shoe shaping or treeing form herein described is especially designed for
button boots and shoes, but it is obvious that it is of equal utility in shaping lace
boots and shoes which are laced up in order that the ankle and top portions may
be shaped, and also in shaping Congress boots and shoes where it is desirable not
to stretch the gores.
Referring to Figures 9 to 12 inclusive wherein a modified construction of form
is shown h represents a back leg portion, or back part of the form, ia front leg
portion, and a slide formed with a groove adapted to receive a rib on the front
leg portion or otherwise adapted to slide thereon, and said slide j is shown as
adapted to be used as a shin piece, and hence is properly formed for such purpose
and detachably connected with its support.
The fore-part is detachably connected with said slide jį, and for simplicity it is
shown as provided at the top with a dove-tailed projection, see dotted lines
Figure 10, adapted to enter a correspondingly shaped groove formed in the end of
the slide j.
The fore-part is composed of two parts m, m³, very similar to that shown in
Figure 5, the upper part as m comprising the instep and toe portions and the lower
part as m¹ comprising the shank piece.
-
The line of severance between said parts m, m³ is more or less curved, and said
parts are connected together in such manner that the shank piece m¹ is adapted
to slide along the bottom of the instep and toe portions.
Such sliding connection is herein shown as made by providing the shank piece m
with two headed studs 20, 30, and the instep and toe portion m with a groove_k40
extending substantially from end to end which receives said studs, 2010, and a
stop is provided, see Figure 11, against which the stud strikes to prevent the
shank piece m¹ being detached.
In Figure 10 the shank piece m¹ is cut off on an oblique line, leaving more
thickness in the part m to which it is attached, but the difference is only in the
location of the line of severance.
In this modified form shown in Figure 10, the studs 2000, are arranged at the
ends of the shank piece m¹ but not in line with each other, and two grooves are
provided 40, 50 the groove receiving the stud and the groove 50 receiving
the stud 30
The stud has a rectangular head which slides freely along in the groove 40
provided for it, but does not turn therein, while the stud 30, is merely a steadying
pin for the toe end of the shank piece.
At the toe end of the groove 40 a flat spring is shown upon which the head
of the stud impinges or bears, when said shank piece m¹ is withdrawn as shown
in Figure 10, and said spring will at such time serve to hold the shank piece in such
position frictionally.
Referring to Figures 13 and 16, wherein another modified construction of form
is shown represents a back leg portion, ia front leg portion having a forward
extension see dotted lines Figure 13, which enters a recess in the back leg
portion h.
10 represents a slide which is formed with a T-shaped or dovetailed groove
adapted to receive a correspondingly shaped rib ¿¹³, on the extension of the front
leg part, and said slide 18 extends to the end of the form and includes the shank
or a portion thereof as represented as 14.
represents another slide, similarly provided with a T-shaped or dovetailed

page_text: groove adapted to receive a correspondingly shaped rib on the slide 18 and said
slide is herein formed as and adapted to serve as and constitute a shin piece.
The fore-part is detachably connected to the slide 3, as for instance, it may be
formed with T-shaped or dove-tailed projection adapted to enter a groove formed
in the end of said slide, and said fore-part is herein shown as composed of a shank
piece m15 and a toe portion m16 the latter sliding upon the former, as for instance,
the toe portion may be formed with a groove to receive a rib on the shank piece m15.
It will be seen by reference to Figure 14 that the slide 13 may be withdrawn,
and then the slide ja withdrawn, as shown in Figure 15, and then the toe portion
of the fore-part may be withdrawn as represented by dotted lines, and in any
event the heel measurement of the form and the instep measurement of the fore-part
is reduced to the ankle measurement of the shoe, so that a boot while buttoned or
laced can be drawn onto and off of the form.
Having now particularly described and ascertained the nature of my seid
invention and in what manner the same is to be performed,
claim is:-
