PROVISIONAL SPECIFICATION.
Improvements in or relating to Machinery or Apparatus for Paring
the Edges and Heels of Boots and Shoes.
We, SOUTHALL'S MACHINERY SYNDICATE LIMITED, of 7 East Parade, Leeds,
in the County of York, Machine Makers, and CHARLES HENRY SOUTHALL, of
18 Chapel Lane, Headingley, Leeds, aforesaid, Machine Maker, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in that class of machines described in the
Specification of Letters Patent granted to the said Charles Henry Southall, the
13th day of June 1890, No. 9149; and its objects are, first, to adapt one machine
to pare both the foreparts and the heels of boots and shoes; second, to readily
adjust the paring tool and other parts of the machine to any desired angle; and
third, to provide means for enabling the tool and other parts to work with greater
accuracy by locking them in position and automatically releasing them at a
predetermined point.
According to the present invention the stand on which the boot or shoe is placed
is made circular for a portion of its length in order that the bedding piece may be
adjusted to any desired angle. For the same purpose the tool holder lever is
attached to a suitable fixing connected to a universal joint, and which is also
capable of being adjusted in a longitudinal direction. The said parts are retained
in the desired position by lock nuts, set screws, or other equivalent device.
Instead of mounting the paring tool rigidly to the tool holder lever, as described in
the herein before mentioned Specification, it is now pivoted thereto so as to adapt
itself to the various angles of the boot or shoe sole in paring the same from one
portion of the breast of the heel round to the same point, say the opposite side of
the boot. Within the tool holder is also mounted a thickness regulating piece
capable of being adjusted by a screw or its equivalent to the varying thickness of
the boot or shoe soles and heels to be pared.
In order to retain the carriage and slide (on which the carriage works) in
position, and thereby give greater accuracy to the working of the paring tool the
slide is armed with pieces which slide on the side of the table of the machine. In
order to retain the carriage in a fixed position, say for instance whilst the tool is
paring say from the heel to say the commencement of the toe, the semi-circular
cam at the bottom of the carriage is held by a retaining lever which is pivoted to
the slide and kept in contact with the cam by means of a spring. The said lever is
locked in position by a tappet lever also pivoted to the slide and thrown out of
action by an incline or cam fixed to the table of the machine. The retaining lever
is moved out of connection with the semi-circular cam by means of a cam
within the slide and a pin fixed to said lever. The carriage is held in position
whilst paring the toe by means of a second cam fixed below or attached to and
concentric with the shaft on which the cam lever (which controls the motion of the
carriage) is mounted, and a runner fixed to said slide.
When the machine is employed for paring the heels of boots the template ordinarily
used is dispensed with, the position of the boot or shoe reversed, and a suitable tool and
bed plate to suit the shape and contour of the heel having been fixed in position
the heel may be pared on the same machine as easily as the forepart and toe.

page_text: Other parts of the machine not described may be of the same construction and
may operate in the same manner as set forth in the herein before mentioned
Specification.

Improvements in or relating to Machinery or Apparatus for Paring
the Edges and Heels of Boots and Shoes.
We, SOUTHALL's Machinery SYNDICATE LIMITED of 7, East Parade, Leeds,
in the County of York, Machine Makers, and CHARLES HENRY SOUTHALL, of
18, Chapel Lane, Headingley, Leeds aforesaid, Machine Maker, 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 that class of machines described in
the Specification of Letters Patent granted to the said Charles Henry Southall,
the Thirteenth day of June 1890, No. 9149; and its objects are, first, to adapt one
machine to pare both the foreparts and the heels of boots and shoes; second, to
readily adjust the paring tool and other parts of the machine to any desired angle ;
and third, to provide means for enabling the tool and other parts to work with
greater accuracy by locking them in position and automatically releasing them at
a predetermined point.
According to the present invention the stand on which the boot or shoe is placed
is made circular for a portion of its length in order that the bedding piece may be
adjusted to any desired angle. For the same purpose the tool holder lever is
attached to a suitable fixing connected to a universal joint, and which is also
capable of being adjusted in a longitudinal direction. The said parts are retained
in the desired position by lock nuts set screws, or other equivalent device. Instead
of mounting the paring tool rigidly to the tool holder lever as described in the
herein before mentioned Specification, it is now pivoted thereto so as to adapt itself
to the various angles of the boot or shoe sole in paring the same from one portion
of the breast of the heel round to the opposite side of the boot. Within the tool
holder is also mounted a thickness regulating piece capable of being adjusted by
a screw or its equivalent to the varying thickness of the boot or shoe soles and
heels to be pared.
In order to retain the carriage and slide (on which the carriage works) in
position, and thereby give greater accuracy to the working of the paring tool, the
slide is armed with pieces which slide on the side of the table of the machine. In
order to retain the carriage in a fixed position, say for instance whilst the tool is
paring say from the heel to say the commencement of the toe, the semi-circular
cam at the bottom of the carriage is held by a retaining lever which is pivoted to
the slide and kept in contact with the cam by means of a spring. The said lever
is locked in position by a tappet lever also pivoted to the slide and thrown out of
action by an incline or cam fixed to the table of the machine. The retaining
lever is moved out of connection with the semi-circular cam by means of a cam
within the slide and a pin fixed to said lever. The carriage is held in position
whilst paring the toe by means of a second cam fixed below or attached to and
concentric with the shaft on which the cam lever (which controls the motion of the
carriage) is mounted and a runner fixed to said slide.
When the machine is employed for paring the heels of boots the use of templates

page_text: ordinarily used are dispensed with, the position of the boot or shoe reversed, and a
suitable tool and bed plate to suit the shape and contour of the heel having been
fixed in position the heel may be pared on the same machine as easily as the fore-
part and toe.
In order that this invention may be more fully understood we describe the
machine as a whole, reference being had to the annexed drawings in which-

Similar letters refer to similar parts throughout the several views.
The
The table or plate A, its legs a a and its standards or uprights a' a', cast or
otherwise, secured to the upperside of the table, constitute the frame-work of the
machine. To the upright a' is cast or otherwise fixed a long horizontal boss or
projection a in which is mounted and fixed a bar a³ so as to project therefrom
parallel, or nearly so, with the table. The bar a³ is preferably made circular in
cross section, and on it is mounted by means of the boss b a curved plate B.
plate B may be adjusted by means of the set screw b¹ in any desired position upon
the bar a³. Between the uprights a' a' is also mounted on the shaft c the double
ended lever C. The lower end of the lever C is provided with a lug c* against
which the end of the screw-shaft c', mounted in bearings provided for its reception
within the table A, is made to work for adjusting purposes. The opposite end of
the screw-shaft c¹ is armed with a handle c². To the top c** of the lever C is fixed
the curved lever or bar C' armed at its free end with a bedding piece c', which is
jointed thereto to hang over the plate B.
The curved plate B and bedding piece care curved to correspond with the
contour of the boot or shoe sole as shown; the centre of the radius of the plates
being at d of the adjusting bar D.
The bar D is mounted horizontally, above the table, in the bearings a¹ a
provided for its reception in the upper part of the uprights a¹ so as to be adjusted
according to the size of the boot or shoe to be operated upon, to permit of the
centre d being immediately, or nearly so, over the centre of the curvature of the

page_text: boot or shoe toe. The adjustment of the bar D is regulated by the collars d¹ d
which are retained in position by set screws. The end d³ of bar D is bifurcated,
see Fig. 25, to receive the block or axial bearing E (Figs. 26 and 27) which is
mounted therein by means of studs or trunnions at d.
In the axial bearing E is mounted by means of the spindle and nut f¹ the
inverted shaped pendent bracket F. By mounting the bracket F (Figs. 22
and 23) by the spindle in the axial bearing E which in turn is jointed to the
bar Da universal joint is provided whereby the paring tool, to be hereafter
described, may be moved in any required direction.
To the bracket is fixed the end g of the lever or bar G (Figs. 34 and 35),
said lever being armed with a handle 91 (Figs. 30 and 31) for directing and
controlling the course or angle of the paring tool. The opposite end g² of lever G
is connected to a sliding part of the carriage H of the machine, by means of the
fixings 93 g and link g (Figs. 28 and 29) to which the said fixings are jointed by
the studs g.
The carriage H (Figs. 9 to 12) of the machine is provided with two uprights h¹
in which the rod 2 slides. The rod is armed at one end with a crosshead ³ and at
the other end with a knob 7' for bringing it in and out of action. The rod may be
kept from revolving by means of the piece ³ mounted thereon so that its lower
surface will slide upon the top of the carriage. On the rod is also mounted the
adjustable sleeve 6 to which is pivotably attached, by the screw ', the fixing g*.
At Figs. 1, 2, 6, 9, and 12 the rod is shown in position for the paring tool to be in
action, and it is kept to its work by the springs, the ends of which are
respectively attached to the crosshead ³ and to the trunnions of the sleeve
The rod is held in its inward position, as shown, by a slotted catch 10 arranged
to slide vertically on the upright h, and to pass into the notch provided for its
reception in the rod. A second notch may also be provided in the rod for
retaining it in its normal position, that is, when the paring tool is out of action.
The carriage H is mounted over and attached to the reciprocating (backwards
and forwards) slide I by set screw i and a circular piece *. The set screw i also
forms the pivot or pin on which the carriage rotates.
28
..
The slide I (Figs. 7 and 8) is provided with a crosspiece I' of the shape shown
at Fig. 8, which is made to extend across the table A. To the crosspiece I' are
fixed, at a right angle therewith, the guides i arranged to slide longitudinally on
each side of the. table as shown at Figs. 2, 4, and 5. In the slotted slide I is a
longitudinal recess for the purposes to be hereafter described. To the face of
the slide I is fixed a circular piece, around the periphery of which the semi-
circular piece ¹³, (cast or otherwise fixed to the underside of the carriage H, and
which is turned to fit the circular piece *) works when the carriage has been
traversed forward so as to bring the centre of piece under (or nearly so) the
centre of the toe of the boot or shoe. The circular piece it is provided with a
stop against which the ends h* and ** of the semi-circular piece 3 are made
to work for retaining the carriage H at or about a right angle with the recess ³ as
shown at Figs. 64 and 6° whilst the tool is paring the edge of the sole,
say from the breast of the heel to the commencement of the radius of the toe
and vice versa. In order to retain the carriage H in the said position and
thereby secure greater accuracy for the working of the paring tool, the
end * or h** of the semi-circular piece 413 is held against the stop by
a catch portion of the lever (Figs. 36 and 37) said catch portion being
adjacent to the point at which the lever is pivoted (at 7) to the slide I. The
lever is armed on its underside with a pin which when the carriage H and
slide I have travelled to nearly the position shown at Fig. 6B engages with a notch
in the form of an incline cam ix formed in the plate (Figs. 47 and 48). The
plate is arranged to slide within a recess 3, formed in the central arm of the
slide I. The plate is fixed to the short vertical shaft J (Fig. 6) by a set-
screw. The lever i is locked in the position shown at Fig. 64, by the notched
end of a tappet lever (Figs. 59 and 60) pivoted to the end of the crosspiece I',

page_text: at or about a right angle to the lever. When the lever is locked by the notched
end of the tappet lever 12, as shown at Fig. 64, the outer portion of the catch
portion of lever will be in contact with the end ** of the semi-circular
piece thereby holding the carriage H at or about a right angle to the central
arm of the slide I. The paring tool to be hereafter described is then in a position
to commence paring at the waist of the boot near the breast of the heel. The
catch end of lever i being retained against the end 4** by the spring ". The
lever remains locked, as described, during the outward traverse of the slide I until
the commencement of the radius of the toe is reached when the enlarged weighted
end of lever comes in contact with the incline ** (Figs. 57 and 58) fixed to
the table A for raising the notched end 13 from its contact with the lever .
Instead of allowing the weighted end of lever i to mount the incline when it is
desired to unlock the lever the weighted end 14 may be arranged to travel upon
the top of a bar with an inclined end, and descend the incline for releasing purposes.
In either case the weighted end 14 may be kept in contact with the table A or bar
by a spring attached to pin . Simultaneously with the raising of the notched end
of lever the cam plate comes in contact with the pin on the underside of the
lever, and by the continued outward movement of the slide the lever is caused
by the plate to turn on its pivot and thereby move the end away from the
end and clear of the semi-circular piece 13 as shown at Fig. 6. As soon as
the end is clear of the semi-circular piece the carriage H and paring tool are
free to revolve round the circular piece and toe of the boot or shoe until the
end ** comes in contact with the stop , when the spring will have returned
the lever to the position shown at Fig. 6° to permit of the inner side, that is, the
side nearest to the pivot, engaging with the end h* of the semi-circular piece /13
for locking the carriage H again at a right angle to the central arm of the slide I,
as shown at Fig. 6º, for paring the opposite edge of the sole from the toe to the
waist.
Simultaneously with the releasing of the pin 8 the runner, mounted on a pin ¿¹
fixed to the underside of the carriage H, comes in contact with the inner periphery
of the concentric cam K (Fig. 38) projecting from the plate K₁ mounted on
shaft J below the slotted lever L.
The slotted lever L (Figs. 55 and 56) is employed for reciprocating the slide I
and rotating the carriage H. To the underside of the carriage H is fixed a plate 14
from which projects a pendent stud 15 armed with a runner 16 arranged to work in
the slot of lever L. When the runner ¹ has been traversed in the slot / to
the position shown at Figs. 1 and 6B and 6, of the accompanying drawings the
paring tool is prevented from moving out of the desired radius by the runners ¹
and being respectively held in position by the end of lever L and cam K.
Motion for traversing the paring tool from the breast of the heel to and round
the toe and back to the breast of the heel on the opposite side of the boot or shoe
is imparted from the winch or other handle J¹ mounted on horizontal shaft J2
through spur gearing J³, mounted on the horizontal shafts J2 J³, and bevel
gearing J mounted on the shafts J' and J.
The paring tool, previously referred to and shown in detail at Figs. 40 to 54, is
provided with a knife M consisting of a flat blade shaped as shown at Figs. 41
and 42 and provided with a cutting edge mxx. The knife is fixed to the face m³ of
the block m² (Figs. 49 and 50). The block m² is mounted in a carrier (Figs. 39
and 40) consisting of an angle piece m fixed to a pivot pin m¹. On the block m² is
also mounted a second block m³ (Figs. 45 and 46) provided with a notch m³ which
passes over the edge m-which is at a right angle to the back m*-of the knife M
for securing the lower portion of the knife to the block m2. The front of the
blade is chamfered to form a cutting edge m**. The two blocks m² and m² are
secured in position on the angle piece m by a single bolt m². The upper edge m³
of the knife M is secured between the plate m³ (Figs. 43 and 44) and welt pro-
tector m (Figs. 53 and 54) armed with a projecting lip m" arranged to pass over
the outer edge of the knife as shown at Fig. 6. The plates m³ and m¹º are held

page_text: together by pin m¹ and set screw m¹ and fixed to the top of block m² by a set
screw m¹, the notch m¹ on plate m³ being arranged to fit into a recess m¹³ formed for
its reception in the upper part of the angle plate m for more securely fixing the
knife M in position. In front of the cutting edge m** is mounted a sole guide m¹7
(Figs. 51 and 52) capable of adjustment vertically to the varying thicknesses of 5
the soles by means of the set screw m18 and it may also be adjusted, if required,
laterally by a second set screw m¹, shown in dotted lines at Fig. 19, working in a slot
provided for its reception in the vertical portion of the angle plate m.
Attached
to or forming part of the sole guide m" is a paring regulator m20, this is placed
slightly in the rear of the knife so that the latter will cut a shaving off the sole.
The thickness of the piece m20 may vary from about three sixteenths of an inch to
any required thickness.
The pivot pin m¹ is mounted and secured by set screw n* in the boss, which
forms an axial bearing n, of the carrier N. The carrier N is jointed at n² to
the lever G as shown, so as to readily adapt itself to the varying curves of the boot
or shoe.
It will be readily seen on reference to Figs. 1 and 3 of the drawings that the
centres of the block E, of the circular piece when the tool is paring the toe, and
that of the toe, or heel, of the boot or shoe are arranged almost in a line with each
other, whilst as long a leverage as possible is obtained between the centres d and n².
Also by mounting the paring tool as described provision is made for adapting it to
the varying contours and curves of the sole.
"
When it is desired to take out "the bit," that is to chamfer the top of the sole
from the " upper to its front edge, on the plate m³, either in addition to or in
place of the welt protector mo, is mounted a "bit" knife m" (Figs. 20 and 21)
provided with a circular hole m² arranged so that its edge m23 not only tapers
away as shown, but also forms the cutting edge for taking the "bit
" out at the
same time that the edge of the sole is being pared. At Figs. 17 to 19 the "bit"
knife m² is shown applied to the plate m³, and arranged to take the place of the
welt protector mo; that is to perform both the functions of both welt protector and
"bit" knife.
The action of the machine for paring the edge of the forepart of the sole is as
follows:-
The bedding piece c¹ is placed within the boot or shoe so that its lower surface will
rest upon the inner sole, whilst the outside of the sole rests upon the plate B. By
mounting the latter plate on the round pin a³ its position will be readily adapted to the
sole. The boot, shown in dotted lines at Fig. 1, is clamped in position on the machine,
with the centre of the toe over the centre of the circular plate 4, by the curved plate B
and bedding piece ct, the requisite pressure being imparted thereto by handle c² through
screw shaft c which forces the end c* of lever C outwards, and the end cxx inwards
carrying with it the bar C¹ for pressing the bedding piece et tightly onto the inner
sole of the boot. The centre d is then adjusted by means of the bar D and
collars d' d so that the centre d shall be approximately over the centre of the toe.
The carriage H having been previously moved to its extreme inner position as at
Fig. 6, that is, near the uprights a', in which position the carriage H will be at or
about a right angle to the longitudinal axis of the bar D, and to the slide I, and
the cam lever L at or about an angle say of twenty eight or thirty (more or less)
degrees to the said slide. The paring tool is then placed in position, after the
rod has been pressed inwards until the catch is fixed in notch h", with the
welt protector m10 (or "bit "knife m21) resting upon the top of the sole, to prevent
the "upper" coming in contact with the edge mxx of the knife M, and the bottom
of the sole resting upon the sole guide m which has then been adjusted to the
thickness of the sole by screw m18. The knife M commences paring at or near the
breast of the heel, say at Fig. 1, at which point the lever G will have raised
the knife owing to its radial connection with bar D and axial bearing E up to its
work, and it is held thereto by means of the rod 2, sleeve 6, spring, fixings g³ g¹
and link 9. By mounting the bar D and spindles f, m³ in axial bearings, and also

page_text: pivoting or jointing the bearing E, the carrier N, and fixing y¹ as described, the
knife M will adapt itself to the varying curvatures of the sole. The carriage H
when in this position is locked by the end of semi-circular piece 13 being held
against the stop by the lever as described. By connecting the carriage H with
the cam lever L, by means of runner 1 pin 15 and plate 4" it is caused to slide in
a. longitudinal direction until the commencement of the radius of the toe is reached,
whenever the handle J' is rotated thereby imparting a rotary motion to the cam
lever L through shafts J J J and gearing J3 J. The carriage H remains in a
locked position until the cutting edge m** of the knife has been brought in a line
with or opposite to the centre of the toe, that is, at the commencement of the radius
of the toe; when this point has been reached the end of lever i will have
travelled up the incline xx and raised the notched end 13 of lever clear of
lever, and at the same time the inclined plate will have acted upon pin 18, as
previously described, for unlocking the carriage H and moving the lever to the
position shown at Fig. 6B; thus permitting the carriage H to revolve on its axis i
around the centre plate fixed to slide 1. At the same time the runner will
have been brought in contact with cam K thereby retaining the knife in position
whilst the toe is being pared. When the carriage H is released from its connection
with lever is the cam lever L causes it to revolve round the centre plate until the
end of the semi-circular piece 41 comes in contact with the stop during
which rotation the knife will have pared the toe. As soon as the end ** is against
the stop the inner side of end of lever then engages with the end /* of the
semi-circular piece for holding the carriage H at a right angle to the slide I as
shown at Fig. 6, whilst the opposite edge of the sole from the toe to the breast of
the heel is being pared.
It will thus be seen that whilst the shaft J and cam lever L are making half a
revolution the knife M is carried completely round the edge of the forepart of the
sole, that is from waist to waist, by first causing the slide I and carriage II to
travel together until the knife reaches the commencement of the radius of the toe
when the carriage H is released and travels alone round the toc, after which the
carriage is again locked when the slide 1, carriage H, and knife M are
simultaneously traversed to a position near the uprights a', as shown at Fig. 6".
During the traverse of the knife round the edge of the sole its angle is regulated
and controlled by the operator by means of the handle g'..
:
the
When the knife has reached a point on the opposite edge of the sole to
catch ho is raised from notch which releases the bar and permits the springs 48
to return the bar to its normal position for the catch to enter notch / thereby
withdrawing the knife from its contact with the edge of the sole.
To pare the heel which requires a wider knife than is used for the edge of the
sole I proceed as follows.
I use a plate B with a flat top as shown at Fig. 3, and a bar or lever C¹ provided
with a curved end is fixed to the end exx of lever C in place of the parts shown at
Fig. 1.
The boot, shown in dotted lines at Fig. 3, is placed with its toe towards the
uprights a', its heel resting on the plate B, and clamped thereon by the curved end
of lever C in a similar way to that described for Fig. 1.
The knife holder m, for the heel paring tool, is pivoted to a carrier N which in
turn is jointed to the lever G as previously described. The knife M shown at
Figs: 13 to 15 is somewhat similar to that described in the Specification of Letters
Patent granted to Robert Heap Southall, dated 20th day of March 1888, No. 4253;
that is, in the drawings hereunto annexed the knife M is fixed to the holder m by
means of wedge shaped plates m² m10 which take the place of the blocks and plates
described for the sole paring tool. The wedge shaped pieces m* may be adjusted
by the screws m24 m23.
Instead of making the welt protector a fixture and adjusting the paring
regulator m2, as previously described, I connect them together and arrange that
they shall be capable of adjustment by means of lever O pivoted to carrier m by

page_text: pin O. The welt protector m¹ and paring regulator m20 are mounted upon the
rod O sliding in the bearings 02 03 and arranged so that the upper end of the rod
shall work between the bifurcated end 0 of lever O. The protector m" is
arranged to work on the seat of the heel, and it is retained in contact therewith by
a spring O placed on the rod O between the bearing O³ and moveable collar O³.
The protector m" may be raised and lowered to its work by means of the lever O.
A second paring regulator O' to work against the top "lift" of the heel may also
be provided when required.
The paring tool is traversed round the heel in a similar manner to that described
for paring the toe, but instead of using the templates and a roller, the top "lift" or
layer of the heel is cut nearly to its finished size before the heel is built and it is
made to take the place of a template, and the hand knife is guided round the heel
by the handle g¹.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improvements in machinery or apparatus for paring the edges of boots
and shoes substantially such as herein described and illustrated, consisting essentially
in mounting the cutting edge of a knife blade in blocks so that the said cutting
edge may be adjusted to the varying thicknesses of edges to be operated upon and
jointing the knife and its carrier to adjustable parts of the machine whereby it will
adapt itself to the varying curvatures of the edge to be operated upon, substantially
as herein set forth.
2. The combination, in a boot and shoe edge paring machine substantially such
as herein described and illustrated, of knife M, holder m, block m², adjustable sole
guide m and carrier N with the slide I, carriage H, lever G, adjustable bar D and
parts connected therewith, and mechanism substantially as described for actuating
the said slide and carriage, as set forth.
3. The combination, in a boot and shoe edge paring machine, substantially such
as herein described and illustrated, with the frame A, slide I, and carriage H, of the
plate fixed to the top of shaft J, lever i, cam K, tappet lever 12 and incline **
fixed to the table A whereby the carriage H may be locked in position on the slide I
during one portion of the slide's traverse, released and free to revolve whilst the
slide remains stationary or nearly so, and then again locked during the return
traverse of the slide, as set forth.
4. The combination, in a boot and shoe edge paring machine, substantially such
as herein described, with the framework A, carriage H, and mechanism for locking
and releasing the same, slide I, and mechanism for imparting motion to the same,
and to the carriage H and cam K, of the knife M and parts connected therewith,
lever G, handle y' and adjustable bar D, so arranged that the knife will readily adapt
itself to the various curvatures of edges of the sole and heel of the boot or shoe, as
