PROVISIONAL SPECIFICATION.
Improvements in Apparatus for use in the Finishing of Boots,
Shoes, and the like.
We, JAMES HEWITT of 17 Upper Tichborne Street, Leicester, Manager of
Public Company, and JOSEPH GARRATT GRIMSLEY of Halford Street, Leicester,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows :-
:-
Our invention relates to improvements in apparatus for use in the finishing of
boots, shoes and the like, whereby the operator may be enabled the more readily to
manipulate the finishing tools, whilst holding the article being operated upon in a
convenient position and grasp.
The apparatus consists of a suitable pedestal fixed in any convenient position
and capable of receiving the circular lower end or tail of a jack or stand, which
may rotate therein as desired. The upper part of the said jack or stand is
formed into an arm having an opening up its centre through which may pass a rod
or bar the upper end of which enters an opening in the last, upon which the boot
or other article is placed.
The lower end of the rod or bar is formed into a handle and carries also a clawker-
which may be pressed into engagement with teeth provided on a horizontal extension
at the lower end of the arm of the jack.
The said extension is prolonged so as to be capable of receiving and adjusting
a vertical auxiliary arm upon which the toe or forepart of the boot may be placed.
In a suitable position in the lower end or tail of the jack we may provide an
eccentric cam and brake motion, so that the jack may be tipped to any angle, and
a circular or universal motion is also provided for by the circular lower end or tail
and held in position by a brake spring or other means and raised or lowered at the.
will of the operator.

COMPLETE SPECIFICATION.
Improvements in Apparatus for use in the Finishing of Boots,
Shoes, and the like.
JAMES HEWITT of Queen Street Leicester, Manager of a Public Company and
JOSEPH GARRATT GRIMSLEY of Halford Street, Leicester, Engineer, both in the
County of Leicester 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 :-
Our invention relates to improvements in apparatus for use in the finishing of
boots, shoes, and the like, whereby the operator may be enabled the more readily
to manipulate the finishing tools, whilst holding the articles being operated upon in
a convenient position and grasp.
The jack being capable of moving round and sideways according to the position
desired by the operator.
That our invention may be well understood drawings are annexed in which:
Figure 1. is an elevation of the apparatus forming the subject of our invention.
Figure 2. a view of the adjustable toe and last holding device or jack, showing
the eccentric cam at the bottom.

page_text: Figure 3 is a view of the shoe or break employed, and
Figure 4 a view partly in section of the jack holder, hereinafter described.
Similar letters refer to like part in all the drawings.
manner.
To carry our invention into effect we construct the apparatus in the following
A suitable pedestal A is provided fixed in any convenient position and
capable of receiving the circular lower end, shank or tail B, of the jack holder b,
this jack holder is provided with adjusting or set screws 6', which come upon the
circumference of the eccentric cam C, to regulate the movement of same. This cam
is situated at the bottom or neck of the jack D which is provided with a hollow
arm E through which passes the rod F pivoted at f', the upper end of the rod
entering a hole in the last f, upon which the boot or shoe is placed, the lower end
of the rod being put through a groove in the extension of the upright E and carries
the clawker which can be pressed into engagement with the teeth funderneath the
jack frame, so as to cause the toe of the last f. to grip the toe-holder G, which is adjust-
able on its arm or holder H, (this arm or holder is also adjustable to suit the various
sizes or lengths of lasts), upon the extension I of the jack frame, and made secure by
the screw nut i or its equivalent. Under the eccentric cam C, is a shoe or break J,
which presses against the cam, and when the jack frame is in the centre the shoe
or break J tightens thereon, but the position of the jack frame is always secured no
matter at what angle. The pressure is obtained by the spring which rests upon
the seat and held adjustable upon the brake rod K, (by the nut 12) which passes
right through the shank or tail B and is regulated by the nut M. An adjustable
collar 6 is provided for the shank or tail B to regulate the height thereof.
The said shank or tail B being held secure by a break spring not shown placed
in one of several recesses inside the top of the pedestal A and operated by the
screw nut L.
The operation of the machine is as follows: After the boot or shoe has been
placed upon the last f, it is moved by shifting the clawker into the teeth f* s0,:
"as before stated," to cause the toe to grip the holder G, and we thus provide a
lasting jack which has an oscillating as well as a circular movement, and so allow
the operator to vary at will the position of the boot, shoe or the like. And an
improved means of holding and tightening the last.
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 lasting jack of the character described the employment of an adjustable
toe rest, in combination with the last support or rod F, actuated by clawker, or
other convenient means, and sliding arm H, with the eccentric cam C, and shoe or
break J, operating in the manner and for the purpose substantially as described.
2. In apparatus for use in the finishing of boots, shoes and the like the herein
described means or appliances for holding and tightening the last, substantially as
described and illustrated.
