PROVISIONAL SPECIFICATION.
Improvements in or relating to Edge Setting Machines.
I, HENRY ALFRED OLDERSHAW of Nos. 38 and 40 Highcross Street,
Leicester in the County of Leicester, Engineer and Machinist, do hereby declare
the nature of this invention to be as follows:-
This invention refers to improvements in or relating to edge setting machines
used in the manufacture of boots and shoes, in finishing the sole edges and waists
thereof and known as "Twin machines " having a driving shaft and tools vibrating
at both ends. In all such machines an eccentric shaft is employed and driven from
the centre, with various ways or means, of imparting a rocking or vibrating motion
to the tool holders, but the jarring experienced causes distress to the operator's
muscles when having held the boot or shoe for any length of time up to the tool.
Now to obviate this jarring, and in order to obtain a more perfect rocking or
vibratory motion to the tool holders, I make the tool holders of such a form, that
the horizontal and curved upper part shall convert the eccentric so that it not
only acts as a guard or protector but allows the cycle of motion to be obtained at
right angles to the fulcrum of said tool holders. To carry out my invention
I arrange at each end of the horizontal driving shaft eccentrics and straps, secured to
such eccentrics in the usual manner, the link connection of the said straps being
made secure by screw nut and bolt to the outer free curved end of the tool holders,
having their fulcrum in or about the centre upon spindles fitted in sockets
immediately under and in line with the driving shaft.
The upper curved portion of said tool holders is shaped to correspond with the
eccentric and strap and lever or link connection so that it is not exposed to view,
and such right angled portion is connected as before stated closely thereto, and
forms a simple, yet a perfect fitting and finish to the machine, without having to
resort to joints or other unsightly and unsatisfactory parts as now employed in such
machines. I can also alter existing machines of whatever construction to and in
accordance with my invention.
Dated this 5th day of December 1894.

Improvements in or relating to Edge Setting Machines.
I, HENRY ALFRED OLDERSHAW of Nos. 38 and 40 Highcross Street
Leicester in the County of Leicester Engineer and 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 refers to improvements in or relating to edge setting machines
used in the manufacture of boots and shoes in finishing the sole edges and waists
thereof and known as "Twin" machines having a driving shaft and tools vibrating
at both ends. In all such machines an eccentric shaft is employed and driven from

n.uscles after having held the boot or shoe for any length of time up to the tool.
Now to obviate this jarring, and in order to obtain a more perfect rocking or
vibratory motion to the tool holders, I cause them to be made in the following
manner. And in order that this my invention shall be well understood I have
annexed a sheet of drawings in which:-
Figure 1 represents a side view of the tool-holder constructed in accordance with
my invention, the "full lines" show how the tools are fitted, the "broken lines"
show them in their working order, and Figure 2 a front view of the same.
Similar letters of reference are given in each of the figures.
To carry out my invention I make the tool-holder or tool carrying bracket
having a lower socket portion A, a horizontal hollow body B and a right angle
curved upper portion or arm B' which is shaped to cover the eccentric strap C, F,
to not only act as a guard or protector "see Figure 2," but allows of the cycle of
motion to be obtained at right angles to the fulcrum I.
Said machines carry an horizontal shaft, at the ends of which are eccentrics in
the form of projections "see dotted line E Figure 2 to which I secure by aid of
screws f, the strap C, F. the outer end G of the said strap being secured on pin fl
to the outer screw threaded end D of the curved arm B1 of the tool carrying
bracket A, which is carried on the fulcrum I fitted in the head or column of the
machine immediately under and in a vertical line with the driving shaft E, said
driving shaft is not illustrated owing to the fact that it is of ordinary construction
and will be well understood.
In so arranging or constructing the tool carrying device that the curved arm B¹
is secured end to end with the strap, and the latter to the pin in end of the eccentric
driving shaft in the manner before described a better finish and fitting is obtained
without having to resort to joints or other unsightly and unsatisfactory parts now
existing in such machines. I am also enabled to alter all existing machines that
are supplied with a revolving shaft arranged to carry vibratory tools for the purpose
of setting the edges or waists of boots and shoes in accordance with my invention.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
1. A tool carrying device in which the cycle of motion is at right angles to the
fulcrum thereof for the purpose and in the manner substantially as described.
2. In edge setting machines of the character described an horizontal driving
shaft, combined with an eccentric and strap the latter attached to the right angled
arm of a tool carrying device arranged and operating substantially as herein
described and set forth.
