PROVISIONAL SPECIFICATION.
Improvements in Stitch Wheeling and Edge Setting Devices used in
the Manufacture of Boots and Shoes.
We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON and
SYDNEY ANSELL GIMSON of the Firm of Gimson and Company The Engine Works,
Vulcan Street, Leicester in the County of Leicester, Engineers do hereby declare the
nature of this invention to be as follows:-
The invention relates to improvements in stitch wheeling and edge setting devices
used in the manufacture of boots and shoes to accomplish edge setting and stitch
wheeling at one operation by circular revolving irons or wheels.
Hitherto circular irons have been used in setting the edges by two irons fitted upon
pins and working on the sole edge at the same time to reduce the vibration when the
sole edge of the boot or shoe is presented thereto. As above stated we propose to
perform two operations at the same time by one revolving iron or wheel cut to the
width desired and having a lip at the inside edge for setting the edges and a serrated
or grooved lip or "stitch wheel" on the inside of the outer lip, the said circular iron
or wheel is loosely mounted on a "preferably" removable pin or axle, screw or the
like, or may be trunnions and a boss on either side of the iron or wheel of the
required width so that different widths of iron can, if necessary be put into the same
socket or tool, the said tool may have a shank or any other suitable means of attach-
ment to any ordinary vibrating tool holder used in edge setting or burnishing
machines, or in hand tools, and fitted thereto and heated in the ordinary way.
The fact of swivelling the iron or wheel reduces the vibration almost to a minimum
and the two operations being executed at the same time produces more even work at
a less cost than heretofore.

Improvements in Stitch Wheeling and Edge Setting Devices used in
the Manufacture of Boots and Shoes.
We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON and
SYDNEY ANSELL GIMSON of the Firm of Gimson and Company now Gimson & Co.
(Leicester) Limited of The Engine Works, Vulcan Street Leicester in the County of
Leicester, Engineers do hereby declare the nature of this invention and in what
manner the saine is to be performed, to be particularly described and ascertained in
and by the following statement :-
This invention relates to improvements in stitch wheeling and edge setting devices
used in the manufacture of boots and. shoes, to enable a person to accomplish the
dual operation of edge setting and stitch wheeling at one operation by the employment
of circular revolving irons or wheels of the kind or similar to those shown in the sheet
of drawings accompanying this specification in which:
Figure 1 represents a tool holder, carrying tools constructed and arranged according
D27

page_text: to this invention and Figure 2 another tool of a like construction to those shown in
Figure 1.
Hitherto circular irons have been used in setting the edges by two irons fitted
rigidly on pins, and both working on the sole edge at the same time for the purpose
of reducing the vibration in presenting the sole edge of the boot or shoe thereto, and
circular irons have also been screwed or keyed to a revolving shaft for the purpose
as above stated. Now by this invention we are able to perform the two operations at
one and the same time by the employment of a loosely mounted iron or wheel A cut
to the width desired at B, and having the lip C upon the inside edge for edge setting,
and a serrated or grooved lip or "stitch wheel" on the inside of the outer lip D, said
circular iron or wheel is loosely mounted on the pin or axle E and removable there-
from upon releasing the spring F which is carried by the screw e upon moving the
handle e, to the right the spring clears the indented end of the axle E, so that
different widths of iron can be put in the one socket or tool holder.
The upper portion of the tool holder G "Figure 1" is of the ordinary kind used in
what are known as "twin" edge setting machines, but the lower portion or arms G₁
is specially designed to carry the revolving irons or wheels A. A'. Or the said irons
or wheels may be loosely mounted on a suitable spindle in any hand, or machine tool
having a hollow or solid shank or other means of attachment, the machine tool
holders have a vibratory motion imparted thereto by the well known means, the said
circular irons or wheels may be provided with trunnions "see dotted line A²."
Figure 2 loosely fitting in a similar holder and in a like manner to Figure 1 of the
drawings, the circular waist iron A' is mostly used in combination with the edge iron
A and is used after the edges and stitch marks have been operated upon. The circular
iron A Figure 2 is of the kind now used and secured to a revolving shaft, we apply
our invention in this case as shown, but the iron is loosely mounted in a similar
manner to those shown in Figure 1. We do not confine ourselves to the shapes
shown for others may be used without departing from this our invention several
widths of iron may also be made in one tool and the lips serrated or grooved for the
purpose, as herein before described.
The fact of swivelling the circular irons or wheels reduces the vibration felt by the
operator in presenting the boot or shoe to the tool to a minimum and the two
operations being accomplished simultaneously more even work is produced at a less
cost than heretofore.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :
1. In hand or machine tools the operation of stitch wheeling and setting the edges of
boots and shoes at one time by the employment of circular irons or wheels having
their outer lips serrated or grooved for marking the stitches, said irons being loosely
mounted upon suitable spindles, axles, pins or trunnions fitting in a holder such
as G, G, substantially as described.
2. A loosely mounted circular waist iron or irons such as A' or its equivalent
for the purpose substantially as set forth.
3. A circular edge setting iron or wheel A, A* having the inside of the outer lip
serrated or grooved, and capable of being loosely mounted in a hollow or solid
shank or other suitable means of attachment to any ordinary vibrating tool holder
for the purpose substantially as described.
4. Improvements in stitch wheeling and edge setting devices used in the manufac-
ture of boots and shoes arranged and operating in the manner substantially as
hereinbefore described and set forth.
