PROVISIONAL SPECIFICATION.
Improvements in or relating to Apparatus for use in connection
with Burnishing and Paring Machinery employed in the Manu-
facture of Boots and Shoes.
I, WILLIAM ROBERT MUDD of Rutland Street, Leicester, Boot and Shoe
Machinist, do hereby declare the nature of this invention to be as follows:-
This invention has reference to improvements in jacks for supporting boots and
shoes in burnishing and other machines.
In some of the machines referred to the boot is clamped against the heel rest by
a block on the end of a horizontal rod movable by a screw and hand lever. The
object of the present invention is to provide improved mechanism for actuating the
horizontal rod before mentioned, for the purpose of fixing the boot in proper
position to be operated upon and enabling it to be withdrawn after the operation
has been performed.
According to this invention the horizontal rod which passes through and has its
bearing in a sleeve formed in the upper end of an upright arm, also passes through
and is encircled for some distance in its length by an additional tube or sleeve,
fixed thereon, and furnished with a spiral groove into which the inner end of a
screw or bolt passing through the ordinary sleeve is received. On the inner end of
the additional sleeve or tube there is screwed or otherwise fixed a suitably shaped
cam or head piece, which, on the horizontal rod being moved forward by the hand
lever to clamp the boot against the heel rest, moves in contact with the irregularly
shaped inner end or cam surface of the ordinary sleeve hereinbefore mentioned, to
maintain the boot in the clamped position for being operated upon.
The horizontal rod is adjustable in relation to the heel rest by a set screw in the
usual manner, but the movement of the rod to place the boot in or out of operative
position is determined by the spiral groove in the additional sleeve and the fixed
screw in the former.

COMPLETE SPECIFICATION.
Improvements in or relating to Apparatus for use in connection
with Burnishing and Paring Machinery employed in the Manu-
facture of Boots and Shoes.
I, WILLIAM ROBERT MUDD of Newark Street, Leicester, Boot and Shoe
Machinist, 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 has reference to an improved construction of boot supporting jack
such as is used in machinery for burnishing and paring the heels of boots and shoes.
In some of the machines referred to the boot is clamped against the heel rest by
a block on the end of a horizontal rod movable by a screw and hand lever.
The object of the present invention is to provide improved mechanism for actuating
the horizontal rod before mentioned for the purpose of fixing the boot in proper
position to be operated upon and of enabling it to be withdrawn after the operation
has been performed.

page_text: supporting jack to illustrate my improved construction.
Figure 2 is a plan of part of the jack.
Figure 3 is a section on the line X X of Figure 1.
Figure 4 is an end elevation.
A is the boot carrying block which clamps the heel of the boot against the heel
rest B in the well known way.
The block A is secured on the horizontal rod or tube C by a screw A¹ or other
means and is adjustable in relation to the heel rest B for various heights of heels
by means of a screwed rod D in the opposite internally threaded end of the rod or
tube C.
The screwed rod D has secured thereon by means of a pin E' a milled edge head
or knob E the turning of which causes the block A to travel to or from the heel
rest B, the extent of such movement being predetermined according to the height
of the heel to be operated upon.
In order to enable the operator to readily move the block A nearer to or farther
from the heel rest Bi.e. into or out of operative position, the rod or tube C is
passed through and is encircled for some distance in its length by a sleeve or
tube F which also partly encircles the screwed rod D and is fixed in position
thereon and against the knob E by a collar D'.
The sleeve F is enlarged at F to admit of the handle G being screwed therein
and to abut against the end of the tubular bearing H, in which it is carried, when
the block is clamping the boot against the heel rest and is in the position indicated
in Figure 1.
The sleeve F carries on its opposite end a cam or head piece J screwed thereon
as shewn, and fixed in position by a screw J², Figure 2 or equivalent means.
On the hand lever G being raised the horizontal rod C is moved forward to
clamp the boot on the block A against the heel rest B and the cam J moves in
contact with the irregularly shaped end of the tubular bearing H.
The sleeve F has a screw F2 fixed in its circumference the upper end of which
enters and moves within a spiral groove H¹ formed in the sleeve or bearing on the
upper end of the jack arm H².
The extent of the groove H¹ is determined by the length of movement of the
horizontal rod required to place the boot carried on the end thereof into or out of
operative position.
In order to prevent the rod or tube C partly rotating or moving in a circular
direction when it is moved to or fro horizontally by the raising of the hand lever G,
it is slotted at C¹ on its under surface to receive the upturned end of a bar K the
other end of which is rigidly fixed by a screw bolt Ĺ to the upper end of the
arm H2.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a jack for boot and shoe burnishing and paring machines the combination
with the horizontally adjustable rod C and boot carrying block A of a sleeve such
as F and cam or head piece such as J constructed and operating substantially in
the manner and for the purpose described and illustrated in the accompanying
drawing.
2. In a jack for boot and shoe burnishing and paring machines the combination
with a horizontally adjustable rod C and boot carrying block A of a sleeve such
as F cam or head piece such as J tubular sleeve or bearing such as H provided
with a spiral groove such as H¹ constructed and operating substantially in the
manner and for the purpose described and illustrated in the accompanying drawing.
3. In a jack for boot and shoe burnishing and paring machines the combination

page_text: with the horizontally adjustable rod C and boot carrying block A and means for
moving the same into or out of operative position of a device for preventing the
rod C and block A moving in a circular direction substantially as described and
illustrated in the accompanying drawing.
4. The improved jack for boot and shoe burnishing and paring machines
constructed, arranged and operating substantially in the manner and for the purpose
described and illustrated in the accompanying drawing.
