PROVISIONAL SPECIFICATION.
Improvements in Stitch Indenting and Separating Machines.
We, JOB LEE of 15 Gladstone Street, Kettering in the County of Northamptor,
Engineer and GEORGE HARRY FOSTER of Mill Hill, Kettering, Boot and
Shoe Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to an improved construction of stitch indenting
and separating machine sometimes termed "stitch pricking" machine which is
employed to throw up and render more distinct the stitches in the soles and waists
of boots and shoes.
"
According to this invention the stitch indenting and separating device or
pricking tool," which may consist of a suitably shaped blade, may be connected
to a sliding or vibrating bar which may be actuated by a lever receiving the
requisite motion from a treadle and connecting rod or equivalent or other suitable
means.
The sliding bar may be preferably spring controlled and the lever may be
adjustable for varying thicknesses of soles.
The lever may be provided with an anti-friction roller bearing on a cam mounted
on a shaft the said cam being shaped so as both to raise the lever and sliding bar
and render the latter capable of being properly actuated by 'the foot treadle and
also to lower the said lever and bar and move them into the inoperative position
as desired.
Other means than those described may be employed to actuate 'the sliding or
vibrating bar and stitch pricking tool as the operator passes the boot or shoe to
be treated, under the latter.

COMPLETE SPECIFICATION.
Improvements in Stitch Indenting and Separating Machines.
We, JOB LEE of 15 Gladstone Street, Kettering in the County of Northampton,
Engineer and GEORGE HARRY FOSTER of Mill Hill, Kettering, Boot and
Shoe Manufacturer 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 bas reference to an improved construction of stitch indenting
and separating machine sometimes termed "stitch pricking machine" employed to
throw up and separate and thereby render more distinct the stitches in the soles and
waists of boots and shoes.
The invention will be fully understood from the following description in reference
to the accompanying drawing wherein,
Figure 1 is a vertical section of a stitch indenting and separating machine
constructed in accordance with this invention and,

page_text: Figure 2 a section of the indenting and stitch separating tool.
A, represents the standard or pillar of the machine, A a table at the upper end
thereof and A 2 two cheeks fixed at one end of the table and between which is a
guideway having therein a sliding or vibrating bar B having secured or otherwise
rigidly attached thereto or formed therewith a dull-edged blade or device B¹ for
indenting and separating the stitches in the waists and fore parts of boots and
shoes as hereinafter described.
The bar by preference works in the angular position shown and has on one side
a pin B2 which enters a slot C¹ in a link C the lower horizontal extension C 2
of which is passed over a vertical rod D and connected thereto by screw
nuts D D 2.
A spring D 3 also encircles the rod and is compressible between the lower nut D'
and the upper face of the table A'.
The said rod has a double-hooked lower end to which are connected two
springs D4 D5 attached also to another similarly constructed rod D 6 fastened
at D7 to a pedal or treadle lever E fulcrummed between two lugs E¹ on the
exterior of the pedestal A.
A screw bolt A 3 passes through the two cheeks A 2 to connect them together
and also through a slot C 3 in the link C and acts as a guide pin to the latter and
insures its vertical movement.
•
On the pin B2 may be a tappet or an anti-friction roller B 3 which when the
machine is in operation is maintained in contact with the peripheral edge of a
cam F mounted on a shaft F' on the end of which are the usual variable speed
driving pulleys (not shown in the drawings).
The action of the machine is as follows:-
The edge of the sole is held under the indenting and separating blade or device
by the operator who at the same time depresses the treadle E by his foot,
thereby lowering the connecting rods D D6 link C and bar B so that the
roller B 3 on the latter is moved into contact with and rides on the edge of the
cam F the shape of which is arranged to raise the bar B and its attached blade B¹
at each revolution and then suddenly, with the assistance of the springs D3 D4 D5,
to lower it.
This vibrating action of the bar B and blade B will be continued so long
as the treadle remains depressed as described and the vibrations of the said
bar may be accelerated or retarded by shifting the driving belt, as will
be well understood, from or to one or other of the speed pulleys herein before
referred to.
While the bar and blade are being vibrated as described, the operator holds the
sole of the boot or shoe under the said blade and moves it along the desired distance
after each descent of and indentation made by the said blade.
Upon the operator removing his foot from the treadle the springs D3 D4 D5
recover their normal condition and raise the anti-friction roller B 3 out of the path
of the cam F and the vibrating bar and blade become quiescent.
The invention is not confined to the particular connective mechanism shown and
described between the vibrating bar and the treadle lever as it is obvious that the
detail of this may be readily varied within the skill of the mechanic.
The bar may also be arranged at any other angle and the cam to impart more or
less fall to the bar and its attached blade if desired.
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 machine for separating the stitches in the soles of boots and shoes the
combination of a vibrating stitch separating and indenting tool and a cam for
actuating the same substantially as described.
2. In a machine for separating the stitches in the soles of boots and shoes the
combination of a vibrating bar and stitch separating tool, a cam for actuating the

page_text: latter and mechanism interposed between the said bar and a treadle lever for
maintaining the said bar in contact with the said cam substantially as and for the
purpose described.
3. In a machine for separating the stitches in the soles of boots and shoes
the combination of a vibrating bar and stitch separating tool, a cam for actuating
the latter, a treadle lever and spring controlled connective mechanism between it
and the said bar substantially as and for the purpose described.
4. In a machine for separating the stitches in the soles of boots and shoes
the combination of a vibrating indenting and stitch separating tool, a cam and
mechanism interposed between it and the said tool for actuating the latter, a treadle
lever and connective mechanism between it and the said tool for causing the latter
to be actuated by the said cam or removed from under its influence for the purpose
described.
5. The improved machine consisting of the parts constructed arranged and
operating substantially in the manner and as and for the purpose described and
illustrated in the accompanying drawing.
