Improvements in Boot and Shoe Treeing Machines.
We, THOMAS SALMON and THOMAS HENRY SALMON, both of Victoria
Works, Kettering, in the County of Northampton, Engineers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improved construction of boot and shoe treeing
machines whereby a boot or shoe can be more easily placed on and removed from
the tree than by the machines hitherto in use thus enabling the boots or shoes to
be removed from the machine without creasing or damaging the uppers, our
improved machine also enabling more than one size of boot or shoe to be treed
up without changing the front or toe part of the tree.
In carrying out our invention we form the front or toe part of the tree in
two parts hinged at the instep, the part, which bears against the front part of the
leg, being inclined inwardly, that is to say, towards the waist, and the said part of
the leg being correspondingly inclined so that when the front part is drawn
outwards the distance between the toe and heel is diminished and the toe portion
can then be turned downwards whereby the toe is brought nearly in the axial line
of the tree. The boot can now be easily placed on the front or toe part of the
tree and being pushed forward the toe part will be brought into the fore part of
the boot and at the same time it will be brought into its normal position.
In order to still further expand the tree, that is to say, from the toe to the heel
we connect the back of the leg part to the key or expanding bar by links so that by
pulling out the expanding bar the leg portions of the tree and thereby the toe and
heel portions will be moved away from one another and thus allow the boot or shoe
to be expanded to the extent required.
In order to allow of operating the expanding bar easily we propose to employ a
pair of cams advantageously operated by a treadle, a suitable spring or weight
being employed to bring the parts back into their normal position when the treadle
is released.
By this construction of tree it will be obvious that more than one size of boot or
shoe can be treed without the necessity of changing the toe part.

We, THOMAS SALMON and THOMAS HENRY SALMON, both of Victoria
Works, Kettering, in the County of Northampton, Engineers, 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 an improved construction of boot and shoe treeing

page_text: machines whereby a boot or shoe can be more easily placed on and removed from
the tree than by the machines hitherto in use, thus enabling the boots or shoes to
be removed from the machine without creasing or damaging the uppers, and
whereby more than one size of boot or shoe can be treed up without changing the
front or toe part of the tree.
In carrying out our invention we form the front or toe part of the tree in two
parts hinged at the instep, the part, which bears against the front part of the leg,
being inclined inwardly, that is to say, towards the waist, and the said part of the
leg being correspondingly inclined so that when the front part is drawn outwards
the distance between the toe and heel is diminished and the toe portion can then
be turned downwards whereby the toe is brought nearly in the axial line of the
tree. The boot can now be easily placed on the front or toe part of the tree and
being pushed forward the toe part will be brought into the fore part of the boot
and at the same time it will be brought into its normal position.
In order to still further expand the tree, that is to say, from the toe to the heel
we connect the back of the leg part to the key or expanding bar by links so that
by pulling out the expanding bar the leg portions of the tree and thereby the toe
and heel portions will be moved away from one another and thus allow the boot or
shoe to be expanded to the extent required.
To allow of operating the expanding bar easily we propose to employ a pair
of cams advantageously operated by a treadle, a suitable spring or weight being
employed to bring the parts back into their normal position when the treadle is
released.
To enable our invention to be fully understood we will describe the same by
reference the accompanying drawings, in which:
Figure is a sectional elevation of a treeing machine constructed neconding to
our invention:
Figure 2 is an elevation of the front part er tree end of the machine shewing
the parts in a different position from that shewn in Figure 1; and,
Figure 3 is a plan view of the other or rear end of the machine shewing
the cams:
Figure 4 is a sectional elevation shewing the arrangement of the expanding bar
in connection with the front and back parts of the tree leg; and,
Figure 5 is a section on the fine 5-5 Figure 4.
a, are the front and rear parts respectively of the leg portion of the tree
and c, d are the two parts forming the toe portion of the tree the said two parts
being hinged together at e and provided with dove-tail projections, as clearly
shewn in Figure 5, adapted to slide in a correspondingly shaped guide 9 in the
part a in such a manner as to permit of the toe parts moving relatively with the
front part of the leg in order that the toe part may turn down to the position
shewn in Figure 2 to more or less correspond with the axial line of the tree.
A suitable stop, such as a screw h, is provided adjacent to the guide y for
preventing the part d of the toe portion from moving out of the said slide.
It will be noticed that the guide y is inclined inwardly towards the waist portion
of the tree whereby as the toe portions are moved outwardly the distance between
the toe and the heel will be slightly diminished.
The front leg part a of the tree is formed with a shank i which is mounted in a
bearing in a bracket k adapted to be fixed to a table, bench or the like, a set
screw being passed through the bearing into a groove in the shauk so as to
permit of the rotary movement of the shank with the tree whilst at the same time
preventing the longitudinal movement thereof.
m is the expanding bar or key of the tree the shank m' of which extends through
a tubular aperture or opening in the shank i and carries on its outer end a double
cam n capable of rotating relatively with the shank and a cam block n' fixed to
the bracket k whereby when the said cam n is turned in the proper direction the
expanding bar m will be moved longitudinally relatively with the leg portions of
the tree.

page_text: o is a spring arranged around the expanding bar shank and at one end pressing
against a washer p in the bearing whilst the other end presses against the
expanding bar, the said spring serving after the expan ling bar has been moved in
one direction by the can to return it to its original position in a manner which
will be readily understood.
9 is a guide screw passed through a slot in the expanding bar and serving to.
retain the latter in its proper position relatively with the leg portion a.
The leg part. is connected with the expanding bar by two links r, r in such a
manner that when the expanding bar m is moved longitudinally, the said leg
portion being held against such longitudinal movement, the said leg part b will be
moved laterally to expand the leg of the tree.
s is a guide pin fixed to the shank i of the tree and t is a guide piece fixed to the
leg part b and sliding upon the guide pin in order to hold the leg part b against
longitudinal movement when the expanding bar m is moved whilst at the same
time permitting of the lateral movement.
is a spring which serves to move back the leg part to its normal position.
The cam n is represented as provided with a lever v which can be connected to a
treadle so as to permit of the leg being expanded and held as long as desired.
w, ware plates which are fixed to the leg portion a and serve to close the space
between the said part a and the part b.
By the construction hereinbefore described it will be obvious that more than one
size of boot or shoe can be treed without the necessity of changing the toe part
owing to the manner in which the rear leg part of the tree is adapted to move
relatively with the front and toe parts thereof.
It will also be obvious that owing to the manner in which the shank i of the tree
is mounted the said tree can be turned upon its axis to permit of affording ready
access to all parts of a boot upon it.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a boot and shoe treeing machine the construction of the tree proper
with a two part toe portion designed to move on an inclined slide on the front
leg portion whilst the rear leg portion is designed to be moved relatively with
the front leg portion by means of an expanding bar operated by a cam,
substantially as described.
2. The improved boot and shoe treeing machine consisting of the parts
constructed and combined substantially in the manner herein before described and
illustrated in the accompanying drawings and operating as, and for the purposes,.
set forth.
