WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 1, Rue Laffitte,
Paris. "IMPROVEMENTS IN MACHINES FOR CHANNELLING AND PRICKING INNER
AND OUTER SOLES FOR BOOTS AND SHOES." [A communication from abroad by
Mary Anner Chesly Holmes, of Newport, State of Rhode Island, United States of
America]
This Invention relates to improvements in machines for channelling aud pricking
inner soles to be used in connection with welted work, or outer soles for turned
work, the object being to channel this kind of soles and prick through and provide
the raised rib or wale of leather left between the two cutters, with a series of holes
uniformly spaced to be subsequently filled in with thread by hand.
In this Invention the leather sole to be channelled and pricked rests with its
grain side upon a feeding wheel, having the bearing for its shaft so supported by a
spring that the feeding-wheel may be raised or lowered.
The feeding-wheel located to act upon the grain-side of the sole leaves amplo
room for the channelling and edge beviling cutters to act, and obviates tearing or
disturbing the position of the rib or wale left on the flesh side of the sole by the
channelling or beviling operation, and through which pass the threads to unite
the upper to the inner, or to be turned sole, whereas if the feed were to operate
upon the flesh side of the sole and engage this rib or wale it would be greatly
injured if not destroved.

page_text: The channel-cutter is made vertically adjustable on its holder, which holder,
together with the presser-foot, guiding-socket, and the bearing which holds the shaft
of the perforating awl are all attached to a separate head made horizontally
adjustable toward and from the edge-gauge which bears against the edge of the
sole; the adjustment of said head horizontally providing for cutting the channel
at the inner edge of the rib or wale at a greater or less distance from the edge of
the sole.
The edge beviling cutter is held in a block pivotted upon an adjustable post, so
as to incline the cutter to correspond with the desired inclination of the bevil of
the edge of the sole outside the rib or wale, and also so as to raise or lower it to
leave the extreme edge of the solo of proper thickness, and so also to adapt the
machine to different thicknesses of stock.
The piercing instrument is so connected with its actuating mechanism that its
action may be stopped or interrupted while the channelling operation is going on,
this being especially desirable to permit the cutters to first act to form part of the
rib or wale, after which the piercing instrument is thrown into action to pierce the
rib or wale at the rear of the cutters.
The Invention consists in the combination with a channelling cutter of a per-
forating instrument to pierce the rib or wale formed by the said cutters.
Also, in the combination with the channelling and bevilling cutter and piercing
instrument of feeding devices, to move the sole to be cut and pierced.
Also, in the combination with the edge beviling cutter of a piercing instrument.
Also, in the combination with an edge gauge for the sole of a channel-cutter
and perforating instrument, made adjustable toward and from the edge gauge.
Also, in the combination with the support for the sole and the channel cutter of
a perforating instrument to pierce the rib or wale, and mechanism between it
and its actuating devices to discontinue the operation of the operation instrument
while the channel cutter,operates. :

the said William Morgan-Brown in the Great Seal Patent Office on the 21st
May 1880.
WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 1, Rue Laffitte,
Paris. "IMPROVEMENTS IN MACHINES FOR CHANNELLING AND PRICKING INNER
AND OUTER SOLES FOR BOOTS AND SHOES." A communication from abroad by
Mary Anner Chesly Holmes, of Newport, State of Rhode Island, United States of
America.
This Invention relates to improvements in machines for channelling and pricking
inner soles to be used in connection with welted work or outer soles for turned
work, the object being to channel this kind of soles and prick through and provide
the raised rib or wale of leather left between the two cutters with a series of holes
uniformly spaced, to be subsequently filled in with thread by hand.
In this Invention the leather sole to be channelled and pricked rests with its
grain side upon a feeding wheel, herein shown as having the bearing for its shaft so
supported by a spring that the feeding-wheel may be raised or lowered.
The feeding-wheel located to act upon the grain-side of the sole leaves ample
room for the channelling and edge-beveling cutters to act, and obviates tearing or
disturbing the position of the rib or wale left on the flesh side of the sole by the
channelling or beveling operation, and through which pass the threads to unite the
upper to the inner or to be turned sole, whereas if the feed were to operate upon
the flesh side of the sole and engage this rib or wale it would be greatly injured
if not destroyed.
The channel cutter is made vertically adjustable on its holder, which holder,
together with the presser foot, guiding-socket, and the bearing which holds the
shaft of the perforating awl, are all attached to a separate head made horizontally
adjustable toward and from the edge-gage which bears against the edge of the
sole; the adjustment of said head horizontally providing for cutting the channel
at the inner edge of the rib or wale at a greater or less distance from the edge of
the sole.
The edge beveling cutter is held in a block pivoted upon an adjustable post, so
as to incline the cutter to correspond with the desired inclination of the bevel of
the edge of the sole outside the rib or wale, and also so as to raise or lower it to
leave the extreme edge of the sole of proper thickness, and so also to adapt the
machine to different thicknesses of stock.
The piercing instrument is so connected with its actuating mechanism that its
action may be stopped or interrupted while the channelling operation is going on,
this being especially desirable to permit the cutters to first act to form part of the
rib or wale, after which the piercing instrument is thrown into action to pierce the
rib or wale at the rear of the cutters.
The Invention consists in the combination with a channelling cutter of a per-
forating instrument to pierce the rib or wale formed by the said cutters.
Also, in the combination with the channelling and beveling cutter and piercing
instrument of feeding devices to move the sole to be cut and pierced, substantially
as described.
Also, in the combination with the edge beveling cutter of a piercing instrument,
substantially as described.
Also, in the combination with an edge-gage for the sole of a channel cutter
and perforating instrument, substantially as described, made adjustable toward and
from the edge gage.
Also, in the combination with the support for the sole and the channel cutter
of a perforating instrument to pierce the rib or wale, and mechanism between it

page_text: and its actuating devices to discontinue the operation of the perforating instrument
while the channel cutter operates, for the purpose set forth.
In the Drawings forming part of this Specification,―
Figure 1 represents in side elevation and partial section a channeling and
piercing machine containing the Invention; Figure 2, a front elevation thereof;
Figure 3, a detail of the block or carrier for the beveling cutter; Figure 4, a detail
of the holder for the channel cutter; and Figure 5, a top view of the presser foot
detached to show its forward extension to act upon the rib or wale and keep it
down between the cutters.
The framework a is of proper shape to sustain the working parts, and has bearings
a¹ to receive the main rotating shaft, upon which is the grooved cam hub b to
receive the roller 'stud c on the lever d, pivoted at d, and connected by link d³
with the arm d³ of the rock shaft held in bearings, the opposite end of the
rock-shaft having an arm de, which at one side is provided with a suitable clamp
by which to secure the curved awl or piercing instrument e to the said arm.
The vibration of the lever d by the cam hub b will cause the piercing instrument
to reciprocate in the arc of a circle; but if it is desired that the said instrument
should not operate when the said cam-hub rotates, then it is only necessary to lift
or turn the disconnecting device f, shown as a short latch pivotted to the link d
(see Figure 1) into the position shown in dotted lines.
This disconnecting device when turned down, as in full lines, acts at one end
against the connecting pin f, fixed at the upper end of lever d and fitted to a
slot 3 (see Figure 1) in the liuk:
When the pin fs and device fare in contact, and lever & is moved, the piercing
instrument must also be moved, but when fis raised, as in dotted lines, the pin f
moves in the slot 3 and the link and piercing instrument remain at rest,
and the piercing instrument may be kept up from contact with the leather of the
sole.
It is obvious that other forms of disconnecting devices may be used without
departing from the Invention, as, for instance, the roller stud c might be so held
on the levor d as to be withdrawn from the groove of the cam-hub, or the end of
the link de might be made as a hook to be quickly applied to or disconnected from
the pin 4.
The bearing d is connected with a head g, having a sleeve to enter a guide g³,
and an car g connected with the said guide g has in it an adjusting screw ',
having a grooved head g to embrace a part of the said head g, and cause it to be
moved horizontally toward and from the edge gage h, for the edge of tho sole being
channelled as the said adjusting screw g' is rotated in one or the other direction.
The holder i for the channel cutter, having a right angled cutting-edge, is
connected with the head g, as is also the guide or stand for the stem of the
presser foot which is held pressed down in any usual way, as, for instance,
by a spiral spring within the stank k, all as common in sewing machines.
Adjusting this head g by the screw 'enables the cutter 2 to cut the channel in
the sole so as to leave the rib or wale more or less reinote from the edge of the sole,
and the piercing instrument is by the same movement brought in position to
properly pierce the said rib or wale, it during all its adjustments taking the same
direction or course through the said rib or walc.
The presser is shown as provided with a roller to lessen friction of the leather
upon it.
The edge bevelling or chamfering cutter 1, having also a right angled cutting
edge (as shown clearly in Figure 3), is adjustably held by the screw 10 between
cheeks of the box 12 pivotted at on a vertically adjustable post 1.
An adjusting screw in the box bears against the said post and tips the box,
so as to incline the edge of its cutter more or less with relation to the surface of
the feeding wheel and support m, so as to bevel or chamfer the sole edge at a greater
or less angle, and by elevating the post the cutter may be made to leave the
outer edge of the sole of the desired thickness.

page_text: The edge gauge for the edge of the sole is herein shown as connected with the
block by the screw 10.
Adjusting the cutter & longitudinally in its box adapts it to cut the inclino
outside the rib or wale of greater or less width, and the distance apart of the right
angled corners of the two cutters 1, 2, governs the width of the rib or wale.
Adjusting the cutter vertically, as may be done by screws 13, 13, enables the
channel at the inner side of the rib to be cut to the proper depth.
The shaft m² of the feed wheel and support m turns in a long bearing sleeve m³
pivotted at m; it is held pressed upward by a strong spring n, and the upward
position of the bearing and consequently of the top of the wheel is determined by
the adjustable stop n³. The feed shaft m² is rotated by a pawl n³ of a pawl
carrier n', the pawl engaging a ratchet wheel n fixed on the shaft m².
The pawl-carrier, shown in Figure 1, and also in dotted lines, Figure 2, is
actuated by the cam p on the main shaft (see Figure 1).
A spring p holds the end of n' against the cam p.
In Figure 5 I have shown the presser foot with its forward extension r to extend
between the cutters 2, 1, and bear upon the leather to be left between them to form
the rib or wale; this extension holding the leather down firmly between the two
cutters, and preventing the rib or wale from being torn up or off.
The bearing m, shaft m³, and wheel m may be depressed when desired by tho
lever pivotted at its rear end upon the frame work a, the said lever being
extended at right-angles across the shaft m².
This lever is in Figure 2 shown as broken off to illustrate the pawl and ratchet
behind it.
Having now described and particularly set forth the nature of the said Inven
tion, and the manner of carrying the same into effect, I would have it understood
that what I claim is,―
First. The combination of channelling cutters of a perforating instrument to
pierce the rib or wale formed by the said cutters, substantially as described.
Second. The combination with the channelling and bevelling cutter and piercing
instrument of feeding devices to move the sole to be cut and pierced, substantially
as described.
Third. The combination with the edge bevelling cutter of a piercing instrument,
substantially as described.
Fourth. The combination with an edge gauge for the sole of a channel cutter
and perforating instrument, substantially as described, made adjustable toward and
from the edge gauge.
Fifth. The combination with the support for the sole and the channel cutter of
a perforating instrument to pierce the rib or wale, and mechanism between it and
its actuating devices to discontinue the operation of the perforating instrument
while the channel-cutter operates, for the purpose set forth.
In witness whereof, I, the said William Morgan-Brown, have hereunto set my
hand and seal, this Twenty first day of May, in the year of our Lord One
thousand eight hundred and eighty.
