Jmprovements in Machines for Stamping the Soles of Boots and Shoes
and other Articles.
We, BENJAMIN TOONE and JOHN WYCLIFFE BLACK, of South Wigston, in the
County of Leicester, Boot and Shoe. Manufacturers, and ARTHUR ADCOCK,
in the employ of the above, of Wistow House, Healy Street, also South Wigston,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to machinery or apparatus for stamping the soles
of boots and shoes and other articles.
The invention is designed to provide a machine which will (1) effect a clear and
indelible impression upon soles or other articles of different thicknesses without
special adjustment for that purpose, and (2) be set in operation by the act of
placing the sole under the stamp.
In a machine constructed according to this invention, the shank of the stamp is
received into the lower end of a vertical spindle reciprocated for stamping pur-
poses through the medium of an eccentric or a cam on the end of a shaft actuated
through the instrumentality of clutch mechanism which is placed in and out of
action through the medium of a suitable lever or equivalent operated indirectly
from a slide which is moved by the sole or other article when placed under the
stamp.
The lower end of the before mentioned lever or a plate or finger formed with or
connected to it, is in contact with a toothed wheel or its equivalent, which upon
the latter being moved forward the extent of a tooth by the before mentioned slide
raises the finger or influences the lever in such a manner as to allow the engagement
of the clutch to take place.
The slide is preferably shaped at its front end to coincide with the end of the
sole or other article, to be stamped, and when the slide is pushed along thereby,
a tooth or finger thereon engages the toothed wheel before mentioned and partially
rotates it but when the slide returns under spring influence to its original position
the said tooth or finger yields to the tooth wheel and passes the latter without
actuating it.
The sole to be stamped is placed upon a platform or rest constructed in such a
manner as to vield under the impact of the descending stamp and while, allowing
the latter to make a perfectly clear impression prevents it cutting through the
material.
The platform or rest may be suitably arranged with a spring or combined with a
spring and counterweight for the purpose named.
The invention is not limited to the exact details of construction herein described

page_text: as these may be varied or modified in various respects without departing from the
main lines of the invention.

Improvements in Machines for Stamping the Soles of Boots and Shoes
and other Articles.
.
We, BENJAMIN TOONE and JOHN WYCLIFFE BLACK, of South Wigston, in the
County of Leicester, Boot and Shoe Manufacturers, and ARTHUR ADCOCK,
of Wistow House, Healy Street,, South Wigston aforesaid, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to machinery for stamping or embossing the soles of
boots and shoes and other articles and is designed with the object of producing
(1) a machine which will effect a clear and indelible impression upon articles of
different thicknesses without special adjustment for that purpose, and (2) be set
in operation by the act of placing the sole, or other article under the stamp.
Reference is made to the accompanying drawings illustrating the invention and
to the following description thereof. Like letters of reference represent the same
parts throughout the figures.
Figure 1 is a perspective view (certain parts being in section) and,
Figure 2 is a side elevation of a stamping machine constructed in accordance
with this invention.
Figure 3 is a central vertical section of the machine and,
Figure 4 is a sectional detail of the clutch mechanism.
A represents the stamp which may consist of letters, figures or designs illustra-
tive of price, size, quality, gauge or other denominative value of goods to be
marked.
The shank of this stamp is received into the correspondingly recessed end of a
vertical spindle A' through which the tongue of a spring plate A2 passes and bears
against the shank to prevent the stamp being jerked out when the machine is in
operation.
The spindle passes through tubular sockets B' 12 forming part of the framing B
of the machine and has screwed thereon a block C provided with a horizontal
groove in which is located a pin or roller 1 eccentric on the face of a disc D fixed
on the end of the driving shaft 2.
At each revolution of the disc, the plate D¹ raises and lowers the spindle A¹ for
stamping purposes as will be understood.
Instead of the eccentric pin, a cam or equivalent may be mounted on the end
of the shaft D to raise and lower the spindle A¹, or as is obvious, the cam or
eccentric might be employed to raise the spindle and a spring on the latter to
suddenly depress it.
The shaft De passes through tubular bearings 133 B in the framing and has
loosely carried thereon a pulley E which derives motion from a belt in the usual
manner.
.
Connected to or formed as an integral part of the said pulley is a stepped
clutch E which, in order to revolve the driving shaft, engages an angular pro-
jecting driving pawl F loosely pivotted at its angle in a bifurcation in a plate F

page_text: the tubular portion D³ of which, besides being passed over the shaft D2 and rigidly
secured thereon by a screw bolt F2, Figures 2 and 3, has a leather faced spring
friction plate D pressing against it to steady its movement after the clutch is
placed out of gear.
Under the opposite end of the pawl F is a spring F3 which, as is obvious, main-
tains the said pawl normally in contact with the edge of the clutch E as indicated
in Figures 3 and 4, and when the said pawl gets under any one of the steps or
noses on the clutch, the latter takes it round with it and thus revolves the
shaft 12 to set the stamp in motion.
When the clutch has made one complete revolution the pawl F comes in contact
with the inclined edge of a disengaging lever G whose upper end projects slightly
beyond the narrowest part of the edge of the clutch E and whose width increases
downwardly so that the said pawl while moving in contact therewith is gradually
directed away from the clutch until it reaches a shoulder G¹ on the said lever and
has its motion arrested thereby, whereupon it will be moved sufficiently from the
clutch to enable the latter to pass it and continue to revolve free of it until again
brought into contact as hereinafter described.
The lever G is, by means of a spring G³ connected thereto and to the framing B,
maintained in the proper position to engage the pawl at each revolution of the
clutch.
A distance pin G³, Figures 1 and 2, on the lever and bearing against the framing
being employed to prevent the lever exerting unnecessary frictional pressure on
the clutch.
When the lever G is moved away from the clutch into the position indicated in
Figure 4, the said pawl, under the influence of its controlling spring F³, is moved
against the edge of the clutch so that it becomes engaged thereby and makes
another complete revolution as before mentioned.
The lever G is furnished with a boss rigidly fixed on a spindle H (both of which
latter are partly cut away in Figure 1 to show the underneath mechanism).
The said spindle is carried in bearings H projecting from the framing B and
with the boss there is also formed an arm G, Figures 2 and 3, the lower bevelled
edge of which rests on the teeth of a ratchet wheel J loosely carried on an arbor J¹
in the upper end of a vertical pillar J² fixed by a screw bolt J³, Figures 2 and 3,
to the bed plate 135.
Each time this ratchet wheel is moved forward the extent of a tooth, the tooth
which passes under the arm G raises the latter in doing so, and as a consequence
moves the lever G away from the clutch as before described.
The ratchet wheel is actuated by a spring controlled tooth K loosely pivotted
between the bifurcated upper end of a block K' rigidly secured to a horizontal
slide rod L carried in bearings 136 137 in the framing and movable to and fro
therein as hereinafter mentioned.
The tooth K rests on a coiled spring K2, shown only in dotted line in Figure 2,
and which is thereby kept up against the ratchet wheel in position for moving.
the latter forward, but when after having done so it returns to its normal position,
as shown in Figures 1 and 2, the said spring becomes compressed and allows the
tooth to yield sufficiently to pass under the ratchet wheel to get in front of the
next tooth of the latter."
The slide rod L is preferably shaped at its front end to coincide with the shape
of the article to be stamped.
In the sole stamping machine, as herein illustrated, a curved plate L¹ is em-
ployed against, which the sole L³ Figure 2 (whose end fits therein) is pressed.
The operator exerts sufficient pressure with the sole to push forward the slide
rod L to cause the tooth K to move forward the ratchet wheel as before mentioned,
so that the shaft D makes one revolution and the stamp descends to impress the
sole before the clutch is thrown out of gear and their action arrested.
Thus as already stated the machine is put in action by the act of placing the

page_text: article to be marked under the stamp and after the operation of stamping, the
machine is brought to a standstill ready for the next article to be placed under the
stamp.
The shank L of the curved plate fits into the tubular front end of the slide
rod L and may be tightened therein by the split block L³ on the end of the said
slide rod.
The curved plate may be readily withdrawn and another of different shape sub-
stituted according to the contour of the article to be stamped.
A spring L, Figures 1 and 2, located between the block K' and the bearing B7
returns the slide after it has been pushed forward, and the extent of its movement
in either direction, is regulated by two shoulders L5, formed on the said slide rod
by cutting away a segment of the latter and the shoulders coming into contact,
one each side of a stop plate Lo, Figure 2, bolted to the framing.
The machine is adapted for making a perfectly clear and indelible impression
upon soles or other articles of different thicknesses without special adjustment
being necessary for each different thickness, to prevent the stamp otherwise cutting
through one material and indistinctly marking the other.
This is effected by placing the unstamped article upon a yielding rest or support
consisting preferably of a removable block M, Figures 1 and 2, resting upon a
block M of larger diameter (shown in dotted line in Figure 2) entering a boss B
on the under side of the bed plate and bifurcated to fit over the end of a lever N
fulcrummed between two ears B2, and passing through an opening in a block O
containing an elastic buffer O' which supports and deadens the noise which would
otherwise be caused through the counterweight N on the end thereof, consequent
upon its falling each time after the block had been depressed by the impact of the
stamp descending upon the sole.
It is obvious that either in lieu of or in addition to the counterweight; a spring
might be combined with the block M to ensure it yielding under the stamp.
The invention is not confined to the particular clutch mechanism shown and
described, as any of the well known clutches may be employed so long as they
are capable of being placed in and out of action by or through the action of the
ratchet wheel J.
For stamping or embossing boots and shoes, the latter as is obvious may be car-
ried on any of the well known boot supporting jacks which when moved under the
stamp will actuate the slide rod L to set the machine in motion,
When such a jack is used, the machine would be constructed, so that greater
space was left between the bed plate B5 and the stamp to allow for the passage of
the boot and jack.
This will be readily understood by any mechanician, but one simple method of
effecting this alteration would be by raising shaft D2 on to a higher level and
correspondingly increasing the length of the disengaging lever G.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is:-
1. The application to a stamping or embossing machine of mechanism which
upon the article to be marked being placed under the stamp, will be actuated
thereby to set the machine in motion to cause it to stamp the article and then come
to rest.
2. In a stamping or embossing machine, the combination with the stamp, of a
shaft, a cam or eccentric thereon, clutch mechanism on the shaft, a ratchet wheel
and means between it and the said clutch, to place the latter in and out of action,
and a slide movable by the article to be stamped, to actuate the ratchet wheel sub-
stantially as described.
3. In a stamping or embossing machine, the combination with the stamp, of a
shaft, a cam or eccentric thereon for actuating the stamp, clutch mechanism on
the shaft, a two armed lever, a ratchet wheel to actuate the latter to place the

page_text: clutch in and out of action and means for actuating the said ratchet wheel and
operated by the article to be stamped substantially as described.
4. In a stamping or embossing machine, the combination of a stamp and its
spindle, an eccentric or cam for actuating them, a shaft and clutch mechanism
thereon, a lever for placing the latter in and out of action, a ratchet wheel for
actuating the said lever, a yielding tooth which when moved in one direction will
partly rotate the ratchet wheel and in returning will pass under it without actuat-
ing it substantially as described.
5. In a stamping or embossing machine, the combination with the stamp, of a
ratchet wheel and mechanism interposed between it and the stamp to actuate the
latter, and means capable of being operated by the article to be stamped, to actuate
the ratchet wheel for the purpose described.
6. In a stamping or embossing machine, the combination with the stamp, of
a shaft, cam or eccentric thereon, clutch mechanism for driving the said shaft and
capable of being placed in and out of action by a ratchet wheel, operated by a
slide receiving motion from the unstamped article or its support being placed under
the stamp substantially as described.
7. In a stamping or embossing machine, the combination of a rest or support for
the sole or other article to be stamped and which will yield under the impact of
the stamp for the purpose described.
8. In a stamping or embossing machine the combination of a spring controlled
or counterweighted rest or support for the article to be stamped substantially as
and for the purpose described.
