PROVISIONAL SPECIFICATION.
Improvements in or relating to Edge Setting Machines used in the
Manufacture of Boots and Shoes.
I, SAMUEL JOHN PEGG of No. 275 Humberstone Road Leicester in the County
of Leicester Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to double or twin edge setting machines used in the
manufacture of boots and shoes, and has for its object the application of cylinders
as connecting rods to impart a pendulous or vibratory movement to the tool
carrying shaft so that the machine can be made of a more substantial character,
and that the operator in presenting the edges of the boot or shoe to the tool or
tools shall receive less vibration to the muscles of the arms.
To carry out my invention I arrange in a suitable column or standard having
the usual driving gear attached thereto, and in suitable bearings an eccentric or
driving shaft which shall be in the same plane as the tool carrying shaft, at cachi
end of the former shaft are collars or discs, the eccentric pin of each fitting into
sectional gun metal bearings secured together by screws; the horizontal portion
of the said cylindrical hearings being in the form of cylinders, which receive
plungers arranged upon T shaped sleeves fitted at each end of the tool carrying
shaft. The said sleeves form the upper portion of the tool holders, which are
provided with a lower arm or projection, carrying the edge or shank setting tools
of any well known kind and in the usual manner, so that the operator can present
the edge or shank of a boot or shoe thereto.
By this arrangement all joint pins are dispensed with and the said cylinders are
the connecting rods, (as before stated) for imparting the pendulous or vibratory
motion to the tool carrying shaft.
In the centre of the eccentric shaft is a pulley block carrying a belt from the
driving pulley communicating motion thereto in the well known manner.

Improvements in or relating to Edge Setting Machines used in the
Manufacture of Boots and Shoes..
-
I, SAMUEL JOHN PEGG of No. 275 Humberstone Road Leicester in the County
of Leicester Engineer 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 relates to double or twin edge setting machines used in the
manufacture of boots and shoes, and has for its object the application of cylinders
as connecting rods to impart a pendulous or vibratory movement to the tool carriers,
and the tools fitted thereto or therein.
Also that such machines can be built of a more substantial character and shall
cller less vibration to the muscles of the arms of the operator in presenting the
edges of the boot or shoe to the tool or tools.

page_text: In order that my invention may be well understood I have appended a sheet of
drawings in which:-
Figure 1 is a front view of the head of the machine, Figure 2 a side elevation
of same, and Figure 3 a partly sectional elevation showing a cylinder with
lubricating box and method of connection with the eccentric shaft B.
Similar letters of reference represent like parts in all the figures.
To carry out my invention 1 arrange in a suitable column or standard A
provided with the usual gear for driving the machine, and in suitable bearings an
eccentric or driving shaft B which is in the same plane as the tool carrying shaft
or spindle C, at each end of the former shaft are collars or discs C₁, the eccentric
pin C, of each fitting into sectional gun metal bearings C³, the horizontal portion of
the said cylindrical bearings are secured by screws C₁, and form cylinders C³, which
receive the plungers D arranged upon T shaped sleeves E fitted at each end of
the tool carrying shaft or spindle C. The said sleeves E forming the upper portion
of the tool holders F which are provided with a lower arm or projection carrying
edge or shank setting tools G of any well known kind, and in the usual manner so
that the operator can present the edge or shank of a boot or shoe thereto. The
edge tool G shown upon the right side of Figure 1 is provided with a gutter in
the top of the body to catch any oil that may drip from the tool-holder. The
tools Gat the left side of Figure 1 are semi-rotary edge and waist irons. Either
one or both sorts can be used from time to time if desirable.
It will be well understood that I do not lay claim any construction of edge
setting tool, for any suitable tool or tools can be mounted on the spindles or tool
carrying shaft without departing from the spirit of my invention. And it will be
obvious that by the arrangement hereinbefore described and shown in the drawings
accompanying this Specification that all joint pins are dispensed with and the
aforesaid cylinders C, are the connecting rods for imparting the vibratory or semi-
rotary motion to the tools on the tool carrying spindles, or shaft. It will be seen
by reference to Figure 1 that in the centre of the eccentric shaft B is a pulley G*
carrying a belt from the driving pulley (not shown) communicating motion thereto
in the well known manner.
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 I
claim is :-
1. Obtaining a vibratory or semi-rotary motion to tools and their carriers in
and for the process of setting the sole edges or waists in finishing boots or shoes
by the employment of cylinders working on eccentrics, and plungers attached to
or forming part of tool carrying devices substantially as described.
2. Improvements in or relating to edge setting machines used in the manufacture
of boots and shoes. Substantially as described and set forth.
