Improvements in Boot Trees.
1, THOMAS GEORGE STEVENS, of 5, The Terrace, Greenhithe, in the County of
Kent, Engineer, 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 that class of boot trees in which.a last of the form of
the upper portion of the boot is kept pressed against that portion by means of a
helical spring as decribed in the Specification of my former Patent No. 2615407.
Figure 1 is a side view partly in section of a boot tree for use with top boots.
a is a last of the form of the upper portion of the boot and 6 is a last of the
form of the back portion.
Two rods ed sliding upon each other are pivoted at c d to the lasts a b
respectively. To the rod d is secured a pin e which passes through a slot in the
rod c.
Between the pivot and the end of the rod c is a helical spring f which
by pressing against the end of the rod c always tends to keep the pin e at the
bottom of the slot c³.
In order to give means of adjustment however I usually prefer to employ the
spring rods shown in the figures hereinafter described.
Another rod h which is slotted at h¹ and carries a roller k at one end is pivotted
at its other end to the last b by a pin g. The helical spring secured in the rod by
the pin m always tends to keep the pin g at the top of the slot h¹. On the last c
is a catch n into which the roller k engages.
To fit the tree into a boot the last 5 is turned up against the last a which is
inserted into the toe of the boot. The last 6 is pressed down and the rod h is
pulled up to make the roller k engage with the catch n. The springs fl are thus
both compressed and maintain a steady pressure in the boot.
Figures 2 and 3 are side views partly in section of trees for use with ordinary
boots.
In both figures a is a last of the form of the upper portion of the boot and in
Figures 36 is a last of the form of the back portion of the boot, but in
Figure 2 this is dispensed with and a heel piece o substituted.

As in Figure 1 two rods c d are pivotted at c d to the two portions of the tree.
A helical spring f is retained inside the rods by the pivot and a pin p, which
is secured to the rod d and passes between two of the convolutions of the spring.
By turning one portion of the tree about the other the pin p is moved along the
spring and in this way the distance between the two portions is adjusted and the
strength of the spring modified.
To fit either of these trees into a boot the last a is inserted into the toe of the
boot and the heel piece o or last is pressed down into the heel. As before the
spring is compressed and a steady pressure is maintained in the boot.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A boot tree consisting of a last of the form of the upper portion of the

page_text: boot, another last of the form of the back of the boot, two rods
sliding upon each other, each pivotted to the lower part of one of the lasts, a
helical spring tending to press the rods apart and means for forcing apart the
upper ends of the lasts substantially as described.
2. A boot tree consisting of a last of the form of the upper portion of the boot
another last of, the form of the back of the boot, two rods sliding upon each
other, each pivotted to the lower part of one of the lasts, a helical spring tending
to press the rods apart and secured to one rod by a pin which passes between the
convolutions of the spring and means for forcing apart the upper ends of the lasts
substantially as described.
3. A boot tree consisting of a last of the form of the upper portion of the boot,
two rods sliding upon each other, one pivotted to the last and the other to a heel
piece or another last of the form of the back portion of the boot and a helical
spring tending to press the rod apart and secured to one rod by a pin which passes
between the convolutions of the spring substantially as described.
4. Boot trees substantially as described and illustrated in the drawings.
