We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON and
SYDNEY ANSELL GIMSON all of the firm of Gimson and Company of the Vulcan
Works Vulcan Street, Leicester in the county of Leicester, Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in and appertaining to edge setting and
paring machines used in the manufacture of boots and shoes and refers to an improved
means for effecting the movement of the boot and last holder to the setting or paring
tool which will enable the-rack-having-straight-sides--and one half circular end to
make a semi-revolution without jarring or stopping except at each return movement
of the racks. The machines are constructed with suitable standards, the front pedestal
carrying a table upon which slides the boot and last holder so that the edge of the
fore part of the boot up one side and round the toe and down the opposite side is
brought to the setting or paring tool coming out from between the uprights in the
upper part of the machine. To a slotted table fixed on a slide we have attached a
double rack having a semi-circular end the straight sides of the rack being long
enough to suit the largest boots, into this rack we gear a pinion fixed upon a vertical
spindle at the rear of the machine, this pinion is moved by a straight rack bar working
horizontally into a second pinion fixed upon the same vertical spindle and being guided
by a rocking bracket, the outer end of the rack bar is secured to a pin fastened in the
slot of a disc, or crank fixed upon a second vertical spindle at such distance from its
centre as to obtain the required length of motion, the lower end of this spindle
carrying a pinion gearing with a worm upon a short driving shaft fitted in bearings
and being driven by a pair of pulleys arranged at one end of the said shaft-our
further improvement relates to the edge setting iron whereby the angle of the iron to
the fore part or sole of the boot is regulated automatically and relatively to the
varying angle at which the edge of the fore part is pared, and also to a device for
adjusting the width of the set iron to suit the varying thickness of sole especially for
boots having hob nailed soles. We use a double set iron carried upon the ball end of

page_text: a spindle, the socket fitting the ball end we make at the lower end of the iron, and at
its upper end we attach a guide spindle with spiral spring by which means the setting
iron is pressed on to the fore part at any angle, the spring compensating for any
inequalities of angle and allowing an even pressure to be obtained all along the fore
part edge. To vary the depth of set iron we use a double iron with the lower edge
only having a projecting lip, on the upper edge of set iron is attached a plate having
a screwed hole in it in which the adjusting plate works this adjusting plate fits closely
on one side against the burnishing edge of the set iron and its distance from the lower
lip is regulated by the screw on the screwed top plate before mentioned thus we obtain
a ready means of adapting the width of the set iron to the width of sole and a more
regular semi-circular motion is given to the boot holder both in edge setting and
paring machines of the character described than by the means now employed.

Improvements in and Appertaining to Edge Setting and Paring
Machines Used in the Manufacture of Boots and Shoes.
We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON, and
SYDNEY ANSELL GIMSON, all of the firm of Gimson and Company of the Vulcan
Works, Vulcan Street, Leicester, in the county of Leicester, Engineers, 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 improvements in and appertaining to edge setting and
paring machines, or those machines commonly known as "Southall's" edge setting
and paring machines used in the finishing of boots and shoes, and consists of the
means for effecting certain improvements hereinafter specified.
:
Firstly. We provide a straight rack bar fitted horizontally upon the upper face of
a crank disc to actuate a pinion gearing with a double rack with semi-circular end
carrying a boot holder and last stand, by which a uniform semi-circular and recipro-
cating motion is secured to bring the edges of the sole, or fore part and waist of a
boot or shoe in immediate contact with the edge setting or paring tool employed in
the head of the machine.
"
Secondly. To facilitate the taking off from the last of the boot or shoe in the place
of an ordinary metal last upon which the boot or shoe is placed we use removable
plates each to correspond with the different sizes used for the soles or fore parts of
boots and the like and formed to the ordinary pitch of the sole of a boot whereby all
sizes can be placed on the one stand employed, and by the use of the said moveable
sole plates it is necessary to have contrivances for holding the boot firm in position for
which purpose we employ a grip which comes on the top of the tread of the sole from
arms in a bracket attached to the last stand.
Thirdly. To facilitate the adjustment and regulation of the edge setting tool.
relatively to the varying angle at which the edge of the fore part or sole of a boot or
shoe is pared and to regulate the setting iron to suit the varying thickness of sole,
also providing a stop to regulate the swinging frame 8, and so keep the edge of the
tool from slipping out of the welt and damaging the uppers.
Fourthly. The combination of the aforesaid contrivances to ensure a uniform steady
motion without jarring or stopping in machines such as herein described and set forth
in the accompanying drawings to which I will now refer.
.
Figure 1. is a side elevation of the entire machine the parts which constitute our
invention are marked by "letters," those parts which are of an ordinary character
and to which we have no claim except in conjunction with the contrivances herein
described, are marked in figures.
Figure 2. is a top view of the crank disc D. and shaft E. with the straight rack B.
adjusted on the pin c in the slot, and gearing with the pinion 6¹ in the rocking
bracket or guide c.

the boot N

page_text: Figure 4. is a sectional view of another form of boot holder O, the grip m³ being
held to the tread of the sole by the roller O' coming down the angle end of the
arm O. when by turning the hand wheel P. to move the nut p¹ forwards the lower
end of the lever 02 is also moved outwards, this movement being reversed to liberate
the grip m³ when it is required to take the boot from off the last, the screw p² keeps
the post J. in position.

width of the set iron to the width of sole.
Figure 9. Sheet 2. represents a plan view of the contrivances for actuating the boot
holder, whereby the reciprocating motion to bring the sides of the sole and the semi-
circular movement to bring the toe of the sole to the setting or paring tool is
obtained.

the edge setting tool is supported, tensioned and moved to or from the welt of the
boot or shoe and avoiding it going on the upper.
The same letters and figures represent like parts in all the figures.
.
The machine is constructed and operated in the following manner. 1. is the pedestal.
screwed down on to the base, or bottom frame, 2.. on top of the pedestal is the slotted
table, 3., and slide, 4., upon this we have the double rack 5., having a semi-circular end,..
the straight sides of which are made long enough for the largest size of boots to be
operated upon effectively into this rack is geared the pinion A, fixed upon the vertical
spindle a¹ see figures 1. 2. 9 and 10., this pinion is moved by the straight rack bar B,
working horizontally into the second pinion b¹ fixed at the lower end of the spindle a',
the rack bar being guided by the rocking bracket c., and its outer end secured to a
pin c in the slot of the crank disc D., or crank fixed upon the second vertical spindle E,
at such a distance from the centre as to obtain the requisite length of motion by
regulating the screw in the slot of the disc, (see figure 9.), the lower end of the second
spindle carries the pinion F, gearing with a worm G, on the short horizontal shaft H,
fitted in the bearings and driven from the pulley I, arranged at one end of the
short shaft H. By the operator depressing one side of the treadle J2, the belt fork
shifts the belt 2 on to the fast pulley I, when the whole is set in motion and a steady
and noiseless movement is given to the rack 5, upon which is fitted the last stand 6,
into this stand is put the vertical post J, at the top of which is the angle, or foot
portion K, (which is without an heel, thus it is easy to remove the boot from off the
last, or te put it on,) to complete the last we provide a loose fore part or sole plate L,
having a pin or pins projecting on its under side to fit in the hole, or holes in the
plate, or screwed on to the angle piece at . If the operator requires to change the
sole plate for wanting a different size of boot to be pared or burnished, the plate is
easily removed and replaced by another one. By the device as shown in figure 6, the 1
fore part or sole plate is released by the operator inserting a key into the slot 1², to 1³,
and pressing back the bolt 14, against which the coiled spring, presses, the sole plate
can then be taken out. By this novel construction of last having no heel for the boot
to rest upon it is necessary to provide the boot holders shown in figures 3 or 4. or any
modification thereof, so that the boot is firmly held upon the last, the one shown in
figure 3 takes its bearing from the centre or boss of the upper horizontal lever fitting
in the arms M, one end of the lever being linked at m¹ to a screwed rod m² fitted at
its lower ball end into the socket m³ when by screwing the nut m the pivoted block m
is pressed firmly on to the tread of the sole of the boot N. to hold it firm in the position
desired-In the boot holder shown in figure 4. the pressure of the pivoted block m is 5
obtained by the upper arm O, which takes its bearing near the end; on the upright,
being held down by the roller O' fitted in the upper end of the lever O' which moves

page_text: by the operator turning the hand wheel P, in such a direction that the nut p¹, working
on the screw in the bed of the holder moves the lower end of the lever O forwards;
the last stand J, is fixed in its proper position by the set screw p².
The contrivances for holding, supporting and moving the edge setting or paring tool
are shown in figures 1 and 10. Upon the upper end of the weighted lever 7, is a
Tshaped handle 7 a, by the aid of which the swinging frame 8, can be pulled forward,
the inclined lip 7b, facilitating this in passing through to the front of the head of the
machine, 7c, (as shown in figure 10 sheet 2). When the lip of the tool Q. at the end
of the tool holder or vibrating arm 15, is readily fitted into the welt of the boot or
shoe N. the arm 15, is guided (as shown in figure 10.) that the lip of the tool is put
between the sole and the upper of the boot, by sliding upon the T shaped block Y.
which is set to the height required by turning the milled headed screw Y¹. At the
back of this is a stop Y, which by the regulation of the screw cap Y³, (the end of
which is against the swinging frame 8,) the swinging frame is kept from coming any
further forward, and the tool from leaving the edge of the sole, or injuring the upper,
and the tool is more readily got into, and kept in the welt.
In the back of the swinging frame 8, is screwed the arm Z, which carries at its
outer end the hand wheel z¹ mounted on the screwed end of the hook z which tightens
or slackens the circular spring 13, secured to the head of the machine on the hook 2-
which holds the swinging frame towards the head of the machine and by which means
any regulated pressure can be brought to bear upon the boot during the edge setting
or paring operation, the vibrating motion is imparted to the angular arm 15, by the
lower end coming against, or to the under side of a cam on the revolving shaft 17, in
the top of the swinging frame, which is operated by the pulleys 18, and 19, carrying
the belts 20 and 21, the latter being put at its lower end upon the pulley I³ (shown in
figure 9).
23, is the gas tube to heat the setting iron.
The swinging frame 8, is pivoted at the rear of the table 3, and connected to the
lever 9, to which is attached the connecting rod 10, having at its lower end the crank
lever 11, fixed in the bracket 12, on the base of the machine.
The swinging frame is lifted by the operator depressing the treadle 22, shown in
dotted line in figure 1. thus we provide for controlling the edge setting tool in its
relative working position to the boot or shoe to be operated upon.
The edge setting tool Q is constructed having the setting iron R, carried upon the
ball end of the spindle 16, at the upper end of the tool we have the guide spindle S,
having a coiled spring T, upon its lower end, and the spiral spring U, in conjunction
with the side springs u¹ by these contrivances the setting iron is kept with an even
pressure to the edge of the fore part or sole of the boot or shoe at any angle, the
springs compensating for any irregularities of angle.
To vary the depth of set iron to suit the varying thicknesses of sole we use a double
iron with the lower edge V projecting, this fits between the upper and sole in the
paring or burnishing operation, on the upper end of the set iron is attached the
plate W, in which is fitted the adjustable plate w¹, this adjustable plate fits closely on
one side against the burnishing edge of the set iron and its distance from the lip V is
regulated by the screw X, thus we obtain a ready means of adapting the width of the
set iron to the width of sole.
It will be readily understood that paring the heels of boots and shoes can be done
by reversing the last stand J, that the back shall come under the tool and dispensing
with the sole part L, and put a plate shaped to the top piece of an heel upon the end
of the angle piece K, so that the grip m³, will then come on to the heel by the means
specified and shown in figures 3 and 4.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination in an edge setting and paring machine, for finishing boots and
shoes of a reciprocating and semi-circular movement to the stand carrying the boot

page_text: by a pinion A, upon the vertical spindle al gearing with the double rack 5, and moved
by the rack bar B, and pinion with rocking guide C, the crank disc D, on second
vertical spindle E, operated by the pinion F, from the worm G, on the driving
shaft H, for the purpose hereinbefore described.
2. In combination with the beforementioned contrivances, the last stand J, having
an angle piece K, and loose fore part, or sole plates L, (or beel plates) adjusted
in the manner specified and to hold the boot firm thereon the boot holders M and O,
or any equivalent thereof.
3. In combination with the contrivances described the means for regulating,
supporting and holding the tool to the welt of the boot or shoe consisting of the
Tshaped block Y, the set screw Y', stop Y2, the arm Z, carrying the hand wheel =¹,
to regulate the spring 13. to put pressure upon the boot.
4. In combination with the contrivances described the means whereby the edge
setting tool Q is regulated at any angle by the circular springs T and U, and side
springs u¹ guide spindle S, plate W, adjustable plate w¹ setting iron R, with regulating
screw X. all in the manner and for the purpose substantially as hereinbefore described
and set forth.
