Improvements in or relating to Edge Setting Machines Used in the
Manufacture of Boots and Shoes.
1, SAMUEL JOHN PEGG of No. 295 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 edge setting machines used in the manufacture of boots
and shoes of the kind provided with vibratory tool-holders at one or both ends of
an horizontal revolving shaft, such tool-holders being carried upon a fulcrummed
spindle; and edge setting, shank or waist irons are fitted to them in arms
projecting at directly opposite angles from a block fitting in a box surmounted by
a stem, upon which. is coiled a spring, such irons and also others are at present
changed by the operator pressing the top of the stem so that the block clears the
box, and turning the tools, when by releasing the stem the said block is again
secure in the box, but in doing this the operator is obliged to take one of his hands
from the boot or shoe that he is holding up to the tool.
Now the object of this my invention is to provide arrangements or facilities
whereby this can be done without the operator taking his hand from the boot or
shoe in presenting it to the tool, and which will by the operator depressing foot
treadles or knee levers enable him to change such tools at will, for example, after
setting or burnishing the edges or forepart and arriving at the shank the tool
required can be at once brought to the operative position, and the other, or others
moved to their inoperative position out of the way.
To carry out my invention I proceed to make a circular tool holder in the form
of a disc, or discs of a suitable width and dimensions, made of steel. or other
suitable metal or material, or may be polygonal, or other useful shape if desired
and at each half of the circle on opposite sides of the periphery of the disc, or
discs, a groove is made of a depth corresponding to that of the links of the chain
employed to lie therein, the inner ends of the chains are secured to the ends of the
grooved out portions of the disc, or discs, and carried in horizontal grooves along
each side of the spindle, at the end of the spindle the said chains are passed over
grooved pulleys and pass down inside the vertical column or standard of the
machine and secured to levers on the rod of the foot treadles, said chains are kept
properly adjusted by suitable screws and nuts fitted on the chains at a point easily
accessable to the operator. The said tool-holders are provided with trunnions or
axle pins and carried in side plates or supports secured with a top to the sides of
the body or fulcrummed portion of the tool-holder, each tool-holder is held secure
in both positions by springs having their upper ends secured to a cross bar inserted
in the column or standard and their lower ends to the levers on the treadle
shaft.
The said tool-holders turning in a vertical plane, the tool or tools moved
uppermost out of the way to the inoperative position are not exposed and are less
liable of getting too-hot.
The said arrangements can be applied to any single or twin machine carrying
vibratory tool-holders, and I do not confine myself strictly to circular tool-holders
for other convenient shapes may be used that the tools therein can be inter-
changeable without the operator turning the tool-holder by hand. Or do I confine

page_text: myself to the above mechanism for changing the tools, for a variety of different
gears and methods for accomplishing this may be provided without departing from
the spirit of my invention and knee levers or foot treadles connected thereto or
therewith. Such as for example, as rods and links, cords, wire, wire ropes or a
combination of levers or gears, racks and pinions, or cranks and levers set at
opposite active positions to each other, but the means herein-above described are
preferred.
Such interchangeable movement of the tool-holders in single or twin edge setting
machines have not bitherto been accomplished, except by hand in the manner
herein first above mentioned.

Improvements in or relating to Edge Setting Machines Used in the
Manufacture of Boots and Shoes.
I, SAMUEL JOHN PEGG of No. 295 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 edge setting machines used in the manufacture of boots
and shoes of the kiud provided with vibratory tool-holders at one or both ends of
an horizontal revolving shaft, such tool-holders being carried upon a fulcrummed
spindle and edge setting, shank or waist irons are fitted to them in arms
projecting at directly opposite angles from a block fitting in a box surmounted by
a stem, upon which is coiled a spring so that the irons can be changed round by
the operator pressing the top of the stem, the block clears the box, the tools are
turned, the top of the stem again released, the block is then secure within the box,
but in doing this the operator obliged to take one hand from the boot or shoe
which he is holding up to the tool.
Now the object of this my invention is to provide arrangements or facilities
whereby this can be done without the operator taking his hand from the boot or
shoe in presenting it, or holding it to the tool, and which will by the operator
depressing one side of foot treadles or knee levers enable him to change such tools
at will, for example; after having burnished the edges or fore part and arriving at
the shank of a boot or shoe the tool required for this part can at ouce be brought
into the operative or working position or removed to it or their inoperative position
clear out of the way.
That my invention may be clearly understood reference is made to the accom-
panying sheets of drawings in which:
Figure 1 represents partly in section a side elevation of a twin edge setting
machine of the type forming the subject of my former Patent No. 2926 of 1894,
and shows the means of connecting the coutrivances forming the subject of iny
present invention-one of the side plates are removed, also one of the caps of the
axlo pins to shew the method of construction.
Figure 2 shows the same machine or the upper part of it, in front clevation and
column partly in section, the front plate at one end is removed also in this figure,
but one is shown intact.
Figure 3 is a full sized view of the circular tool and chain carrying device in
accordance with this invention.
Similar letters of reference refer to like parts in the several views.
In carrying out my invention I cause the circular tool and chain holding device A

page_text: to be made in the form of a disc or discs a, the body of which corresponds in its.
dimensions it is made of steel or other suitable metal or material, and it may be
made polygonal or of any other useful shape. At each half of the circle on.
opposite sides of the periphery of the body of the tool-holder grooves b are made
to admit of the free passage of the links of the chains the inner ends of the chains
being secured by pin c, passing through the disc's; and through horizontal
grooves d cut in each side of the spindle D, and each are passed over grooved.
pulleys E and down inside the vertical column or standard of the machine and.
secured to rods F fastened to the levers G, secured upon the horizontal shaft
carrying the foot treadles H, the said chains are kept properly adjusted by
screws h, and nuts h¹, fitted on the chains at a point I easily accessible to the
operator. The said tool-holders are provided with trunnions or axle pins J
secured by bosses ; and side plates K or supports secured with a top K' to the sides
of the body or fulcrummed portion of the tool-holder, cach tool-holder is held
secure in both positions by springs L having their upper ends secured or hung on
the cross bar M "see Figures 1 and 2," secured through the column or standard by
nuts m, the lower ends of such springs secured to the levers G, or to holders and
rollers g, working in the slots N of the said rocking levers G rigidly secured to the.
foot treadle shaft carrying the treadles H.
The said tool-holders turning in a vertical plane, the tool or tools moved
uppermost out of the way, as a', Figure 2 being inoperative are not exposed and
are not liable of getting too-hot. It will be well understood that although only one
set of rods and chains are shown in the drawings, two are essential and come.
behind each other in both views as seen in Figures 1 and 2. and when the side of
the foot treadle H which is uppermost as 2, Figure 1 is depressed the lever G
turns with it and so alters the position of the tool and of the controlling
spring L.
The aforesaid arrangements can be applied to other single or twin machines.
carrying vibratory tool-holders, than that shown and I do not confine myself
strictly to circular tool-holding devices for other convenient or even ordinary
shapes can be altered to revolve or slide that they can be made interchangeable.
without the operator turning the tool-holder by hand. Or do I confine myself to
the above mentioned mechanism for partly revolving and changing the tools which.
have their edges cut to fit the sole edge waist or other portion or part of a boot or
shoe in the ordinary way for a variety of different gears and methods of partly
revolving or sliding the tool-holder or may be the tools themselves may be provided
without departing from the spirit of my invention, and operated by knee levers or
foot treadles connected thereto or therewith as the case may be. Such as for
example; rods and links, cords, wire, wire ropes, or a combination of levers or
gears, racks and pinions, or cranks and levers if to slide the tools set at opposite.
active positions to each other, but the means hereinbefore described aud illustrated
in the accompanying drawings are preferred.
I am aware that tool-holding devices used in single and twin edge setting
machines have been interchangeable by hand and turn in an horizontal plane by
the means as herein before described but a partial revolution or sliding movement
has not hitherto been accomplished except by hand as previously stated.
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. In single or twin edge setting machines used in the manufacture of boots and
shoes the employment of a circular or other shaped tool-holding device capable of
being partially revolved that the tools are interchangeable, and brought into, or
"out of" their working position, and held perfectly firm in either positions by the
arrangement of springs and rods and operated by foot or knee treadles in the
manner set forth.
2. In a tool holding device for interchanging the tools at will in edge setting

page_text: machines used in the manufacture of boots and shoes, the arrangement on a
circular or other shaped body, of slots to receive the shanks of waist or edge setting
irons, and grooves or the like for the reception of chains, cords, wire, wire ropes
secured in opposite directions, their lower ends attached to rods connected to
rocking levers mounted rigidly on the foot or knee treadle shaft, the axle pins or
trunnions thereof being carried in plates secured to the vibrating spindle of the
machine substantially as described and set forth.
.
3. An interchangeable tool holding device capable of being partially revolved in
a vertical plane so that the tools can be changed without the operator releasing his
hold on the boot or shoe in presenting or holding it to the tool.
4. The herein described improvements in or relating to edge setting machines
used in the manufacture of boots and shoes.
