Improvements in or relating to Slugging Machines.
I, WILLIAM BESTWICK MAXFIELD, of No. 19, Bowling Green Street and Regent
House, Regent Street, Leicester, in the County of Leicester, Registered Patent
Agent, being a communication from James Willson Brooks, Trustee of The
McKay Metallic Fastening Association, of No. 108, Summer Street, Boston, in
the State of Massachusets, United States of America, do hereby declare the nature
of this invention to be as follows:-
وو
This invention relates to slugging machines used in the manufacture of boots,
shoes or other articles of leather, the objects being besides slugging to provide
additional attachments so that quilting and slugging top pieces of heels can be
accomplished on the same machine, also to dispense with the coiled spring as
hitherto used for controlling the driver, feeding the wire from the inside of the
coil, and delivering it to the divided throat guide in an upright position instead
of an angular one, which latter bends and strains the wire, also facilities for
tipping and adjusting the throat, and awl, moving the wire guide up to the
movable knife, and means for instantly changing the size of wire, this latter
operation being in machines now in use, a troublesome one. The said machine
is constructed and arranged in the following or equivalent manner, a standard
is made similar to those generally employed in this class of machine, the wire coil
being mounted in a bracket secured to the top casting, the end of the wire to
be carried down the raceway into the machine being led through a hole inside
the coil, the wire feed wheel has each tooth divided into half by two pawls the
object being to obtain a "positive" length of "slug" determinable by a ("stop"
coming in contact with a cam on the front face of a figured and equally divided
grooved disc or wheel, a blade spring pressing into the grooves thereof to hold
it from further movement, upon a roller attached to the outer end of a spring
pressed lever working in the inside track of a double cam wheel on the main
shaft; the driving bar carrying the driver is controlled by a cam wheel mounted
on the front end of main shaft and keyed thereto by a taper pin or peg, the outer
cam surface or groove carrying a roller on end of a bell crank lever its inner
end being connected to the awl slide. The awl and driver cam wheel upon the
front of the machine has indices upon its face, or upon a plate secured thereon
with the following instructions which correspond with figures stamped in the
outer rim of the wheel for the purposes of adjusting the ball collar, for setting
the knives, for lining throat wire guide, lining throat and setting driver,
adjusting length of slug," adjusting release pawl, free the horn cam lever,
adjust wedge spring and brake, and set the awl-these are all accomplished by
turning the wheel to a pointer in the front of top casting, and driver slide of
the machine. The throat is double and adjustable on end of slide and moves to
and from the knives, driver and presser foot, the latter being screwed to the
side of the head, the throat is provided with a tipping motion to receive the wire
without bending or straining it, said threat is adjusted according to the thick-

page_text: ness, size, or shape of wire employed by a toothed lever engaging teeth in a
throat slide carried in or on a parallel bed, said slide lever is hinged to the
top casting or frame of the machine by means of a stud and carries in its
centre a stud and coned roller excentrically governed by an outside eccentric,
secured by a locking nut, the end of the stud carrying the coned roller being in
engagement with the ordinary cam on the main shaft, said coned roller is
capable of adjustment and takes up with and is secured by an adjustable stud,
and a strap lever carrying a roller is mounted on the throat slide and is capable
of causing the slide itself to be adjusted inasmuch that by motion of the cam,
the cam lever engaged therewith allows the slide to have the tipping motion,
when the throat receives the wire before the knives meet and cut it.
In the casting carrying the stationary knife is a horizontal slide, the inner
end of which carries a block and V wire guide, when the throat slide has
returned back to its normal position the guide is knocked forward by, the point
of a circular tappet formed with the movable knife bracket and encircling or
partly encircling the throat slide or sliding shaft carrying the double throat
piece, the wire is delivered ready for cutting, a top piece or edge guard is
pivotally connected to the frame and is constructed having a cam lever to tighten
and move the arm backwards or forwards with the presser plate, the cam pro-
jection coming against a stop on the guard bracket when regulated by a screw.
and nut fitting therein.
To facilitate the exchange of wire and allow access to the driver, throat and
awl a spring pressed shutter is hinged to the front casting.
..
An awl feed rocking lever slide is carried in a bracket on the driving shaft
and at the rear thereof is a split socket centrally bored to receive a fluted pin
or toothed stud which when inserted becomes engaged with a toothed block sliding
vertically in the upper bracket immediately over the stationary knife bracket,
and by turning the stud with a wrench a more or less throw of the awl is
obtained, thereby adjusting the awl centrally, the bearing in rear of this carries
a lever and roller engaging with the cutside groove in the front face of the
second cam wheel, the stud of the lever is eccentric and allows of the lever to
be adjusted accordingly. To govern the machine and ensure one complete
revolution at the depression of the foot or starting treadle a spring pressed
pawl, connected to the side of the brake lever is withdrawn from a grooved spring
catch which allows of a swinging roller bracket (the stud of which is eccentric
to the roller for purpose of adjustment) to engage with the face of an oval cam
on the driving shaft. The column of the machine is what is called
The rapid
standard column" and employs the same contrivances for putting an upward
pressure upon the horn post.
"
a con-
The horn treadle is mounted in suitable bearings and balance weighted, and
connected to the horn post by a pivoted lever with attachment to an adjustable
rod secured to the bottom of a trothed slide or rack carried in bearings at the
rear side of the column of the machine, another slide is also carried in the
same bracket and has at its lower end an hinged pawl with ratchet;
necting rod is secured to the top of a second slide, its upper end fastened to a
cam lover engaging with the lifting cam, when the lifting action of the latter
takes place the ratchet takes in the teeth of the lower slide and the horn drops
to relieve from pinch and allows the awl to carry the work along freely without
this the work would be carried along under pressure, the cap of the bottom
bracket carrying the hinged pawl and ratchet is adjustable longitudinally to
give the rack slide a more or less" lift.
The lifting cam wheel and driving cone is enclosed and gripped by a V shaped
brake controlled by a shipper rod (spring pressed and vertically adjustable) carried
upon the outer end of the starting lever, the wedge fork of which is in engage-
ment with a wedge bleck corresponding in its inclined face and fitting thereto
which presses the cone driving pulley against the driving cone and so releases
the brake and liberates a V shaped hand wheel on the outside edge of cone

page_text: and cam wheel, said shipper rod block is carried on the driving shaft in rear
of driving pulley, and has ball bearings inserted therein held in place by rings
and a locking nut similarly supplied with ball bearings and secured on the
screwed end of the driving shaft to keep all friction off the shipper wedge in
stopping or starting the machine, the brake shipper rod connecting lever fits in
a groove in the shipper rod and is rocked or turned up or down on its pivot by
a hand lever which operates a slide and causes the outer end to raise or lower
the shipper rod wedge to regulate and alter the relative positions of the wedge
and shipper rod. The inside boss of the driving or crown faced friction pulley
is supplied with three or more pointed blade springs which come upon the face
of the cone or inner cam, and parts the two by pressure of the springs when
the shipper rod falls, and by reason of the dishing out of the shipper, brake and
bumper cam.
At the side of the machine is provided (cast with the frame) a spring oil
can stand or holder so that the oil can may be always to hand when required.
For the purpose of quilting the sole with "slugs" a particular post is supplied
which fits upon the horn post, the upper part being composed of a flat bed or
table upon which a spirally, coiled or circularly grooved plate travels according
to the pattern it is desired in depositing the "slugs" suitable means being
provided for the movement of the pattern plate or plates, and securing the sole
or other leather upon pins in the outer face of the plate.
To undertake the slugging of the " top piece" of the heel of a boot or shoe
while upon the last a jack is supplied having a universal movement in a bracket
capable of being fitted upon the horn post, different sizes being employed for
the various sizes for men's, women's and children's goods.

Improvements in or relating to Slugging Machines.
I, WLLIAM BESTWICK MAXFIELD, late of No. 19, Bowling Green Street, now of
No. 34, Belvoir Street and Regent House, Regent Street, Leicester, in the County
of Leicester, Registered Patent Agent, being a communication from James
Willson Brooks, Trustee of the McKay Metallic Fastening Association, of
No. 108, Summer Street, Boston, in the State of Massachusets, United States of
America, 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:--
66
This invention relates to slugging machines used in the manufacture of boots,
shoes or other articles of leather and machines of this type are sometimes used
for purposes of fastening not known as "slugging," for example, to attach a
round or split lift to a heel, to provide additional attachments for quilting the
soles or heels, or slugging the top pieces of heels upon the same machine; also
relates to the dispensing with the coiled spring as hitherto used in machines
of this character and fitted on the top casting with ever to press upon the
driver slide for controlling the driver; also to obviate straining the wire by
feeding it from the inside of the wire coil, instead of outside as is now the
case.
Providing means for readily gaining access for instantly changing the size
of wire and providing a safety guard in case of the driver breaking and flying
in the face of the operator by means of a door in front of the head which is

page_text: closed when the machine is in operation. Also relates to facilities whereby the
operator can control and adjust the various working parts of the machine by
indices appearing upon the front cam wheel and a pointer situated over said
cam wheel, contrivances for dropping the horn after the slug is driven, also
to enable the material to be put in the required position for slugging without
first depressing the horn by treadle, as is now the case thus increasing speed
very materially in presenting the boot sole or heels to the machine.
Also relates further to devices for controlling the length of the slugs or nails
and regulating the distance of the "slug" from the edge of the leather and to
jacks to better facilitate the operation of quilting the sole or top piece of a heel
of a boot or shoe while upon the last. The means that are employed for tipping
and adjusting the throat and awl have been previously described in a former
Specification No. 14970 of 1896 and hereinafter again further alluded to.
Several sheets of drawings are annexed in which-

Letters of reference are used to indicate those parts of the machine which have
been previously shown and described in the former Patent No. 14970 of 1896,
and figures are used in the combination of new clements and forming the subject
of the present invention.
66
The present machine is constructed upon the same lines as the one above
mentioned, which is known as The Universal Slugger" and designed as an
improvement thereon for the various purposes specified.
The wire is carried in the reel 1 which revolves freely and without noise
upon the ball bearing spindle 2 which is secured, to the top casting by the screw
nut 2 Figure 1. The head of the spindle 2 carries the ball bearings 3 held by
washer and pin 4, the pin 1" securing the reel. If square or other cross
section of wire is used the reel may be mounted vertically instead of horizontally.
The feeding end of the wire in the latter position is taken from the inside of
the coil and passed through the hole 5 in a lug in the curved spindle 2 Figure 1^,
and carried to the feeding and measuring devices; arranged in the following
manner for obtaining a positive length of slug.
The wire feed wheel A is made in one with the ratchet wheel A* screwed on to
a hollow spindle which in turn revolves upon the axle a¹, the hollow spindle
+

page_text: fitting in the tube of the rocking bracket 11, said ratchet wheel is moved by the
two spring pressed pawls on end of the arm or pawl carrier 11".
The length
of such movement is controlled by the adjustment of the numbered and equally
divided grooved measuring wire feed regulating index wheel 8 which is carried
out by placing the lip end of the blade spring 9 into the proper groove, when
the tail shaped excentric stop cam 7 will by contact with the tail 6 of the rocking
bracket 11 determine the extent of movement of the pawls and feed wheel, and
give the positive length of slug to be passed between the wire feed wheel A and V
grooved guide or presser wheel A° (dotted line Figure 1,) the latter carried by
a spring plate secured to the side of the head by the wing nut A A, the wire then
passes through guideways, wire guide 16, throat or carrier I, cutters and behind
the driver.
The two pawls divide the pawl teeth of the ratchet wheel A* SO
that one pawl will be always in engagement and the other one partly so and
so ensure a finer adjustment of the length of the fastening. The measuring wire
feed regulating index wheel 8 and cam 7 is made in one as seen in Figure 10,
Sheet and secured by the screw 12° to the back curved arm 12** which is
secured to the side of the top casting. The bracket 11 is cast in one with pawl
carrying arm 11", arms 10", and tail 6, (Figure 11, Sheet 4) and the rocking
motion obtained by action of the double cam wheel B upon the roller 10 fitted
on end of spindle 11", carried in the arms 10"; the roller 10 is held to its cam
by the loop spring 11b fitting to the centre of the spindle 11** and to the lug in
the side of the head. The axle a is kept from turning by the spring pressed
bolt 12 (Figures 9 and 11) pressing the inner flat side thereof and a part (dotted
line X Figure 11, Sheet 4) is cut out of the inner end of the tube of the bracket 11
so that the oscillation thereof is not interfered with. The said tube also carries
the lubricating trough 12 in which is placed any suitable lubricating material,
holes are made in the bottom, and also in the hollow spindle for lubricating the
axle a¹.
For the operation of slugging the heel the measuring wire feed regulating index
wheel 8 is set at No. 16 upon its periphery when a slug of half an inch in
length will be obtained. For quilting, if the wheel 8 is set at No. 4 upon its
periphery this will give a slug" of one eighth of an inch in length suitable
for this purpose.
66
Upon the front end of the driving shaft is mounted the awl and driver cam
wheel E controlling the driver bar H, the outer cam groove F of said wheel
carries a roller situate on end of the bell crank lever G (Figure 2, Sheet 2) the
inner end of which is connected to the awl slide. The hub of the wheel E is
made fast upon the shaft by means of the taper peg 9, going through its boss
and the shaft and projecting beyond said boss; said cam wheel E is turned by
a hand tool or wrench to any desired point or number upon its rim the shaft
turning with it, and so moving each cam fixed upon said shaft until they assume
the desired position for making the various adjustments before starting the
machine.
In order to carry out such adjustments the said cam wheel has numbers upon
its rim (Figure 2, Sheet 2) and upon the front face of the wheel is fitted a half
circular dial plate 13 having instructions thereon as follows:-
No. 1. Adjust ball collar, set movable knife, align throat wire guide 16, after
aligning throat I*.
"
No. 2. Align throat and set driver."
No. 3.
6
"
Adjust length of slug."
Set stationary knife," "adjust release pawl."
No. 4. Adjust horn cam lever to move free. Adjust wedge spring and brake
and set awl.
To follow out the above instructions the operator is provided with a book
showing how the above can be carried out the following being the examples.
In setting the movable knife h, the operator will see that the hand lever 39
is in the upward position, then turn the cam wheel E so that No. 1
upon its

page_text: rim is brought under the pointer 14, the wire of the size to be driven is passed
down through the wire passage into wire guide 16 and throat 1, and the knife
cap 1 gently tightened while the knife is pushed forward by the screw (Figure 1,
Sheet 1) until the knife comes in contact with, but allows the wire to pass into
the throat I freely.
In aligning the throat wire guide 16 the wire is passed through and into the
throat I*.
In turning the cam wheel E with No. 2 upon its rim under the pointer 14,
with the hand lever 39 in the upright position, to align the throat 1 with the
driver 1° the outside eccentric 2 secured by the locking nut K is turned so as
to bring the throat I backwards or forwards under said driver I°.
And in order that there shall be no play or lost motion between the throat
slide j and its lever J the excentric stud 132 Figure 1 is used by the turning of
which the teeth of the lever J are caused to engage more deeply with the teeth
of the throat slide j, and only when the cam wheel E is in the last mentioned
position,
The length of slug is adjusted by setting the wheel S in the manner as herein-
before described.
To set the stationary knife with the cam wheel E at No. 3, it is moved so that
it just touches the movable knife when it is secured by the screw nut I.
Instructions for moving the hand lever 39 is also given upon the dial plate 13
at every number and it forms a safety device inasmuch that it would be impossible
to run the machine even if the foot treadle was accidentally depressed if the
operator sees that the hand lever 39 is in the upright position.
Before further describing the necessary instructions for adjusting other parts
of the machine I will give in detail the construction or fitting of the parts and
their relation to each other for the purpose of dropping the horn post auto-
matically after the heel or sole is finished preparatory to the introduction of
other work--Also for adjusting the ball collar 35 before starting the machine.
The lever Vis curved as seen in Figures 3 and 4, Sheet 2 and carries at its
upper end the roller V the whole casting comprising the projection 32b for con-
necting the coupling rod 32" to the part 32* of the brake, the spring in box or
hollow arm 39" tensions the spindle of the hand lever 39, and a hole is bored
through the bottom part through which the spindle is passed for carrying the
hand lever 39, said casting is loosely fitted upon the screw spindle 38. The back
of the lever carries a boss and on that boss is an eccentric split sleeve 32°
clamped on the said boss by a screw (not shown). Upon the said sleeve is loosely
mounted the brake 32 so that when the lever V rocks, the brake is lowered or
raised coming next to the brake 32; on the spindle 38 is fitted the rocking
bracket 32, Figures 3 & 4^, Sheet 2, which has a lower arm 40 carrying the
slide way in which is fitted the slide block 40, the rocking bracket 32 is cast
with the shipper rod lever 36, the free end of which, 37, being made in the form
of a knob to correspond with the groove in the shipper rod T. The rocking
bracket 32 is held upon the spindle by washer and screw nut. The sliding
block 40 is operated by an eccentric on the spindle passing through the hole in
the bottom of the lever V1, to the outer end of which the hand lever 39 is secured.
In or about the centre of lever VI is a pocket containing a spring pressed bolt 41"
the outer end of which impinges against the pivoted end of the release pawl
finger 41. In conjunction with the aforesaid the horn cam lever R carries a bent
lever r, with the roll, engaging the machine cam 2, and a steel bunter 47 is
recessed into and secured by a screw in the opposite end of the horn cam lever R
(Figure 4, Sheet 2). In about the centre of lever R is a long hollow spindle ³,
carrying within it a long solid spindle of the lever 43, the hollow spindle is
further carried within a hole in the casting R° in the head (Figure 1, Sheet 1),
both levers R and 43 rocking therein, the outer end of lever 43 carries the roller 44
on an eccentric stud which is capable of adjustment so as to bring the roller
more or less upon the face of the cam 45 and thus ensure that the pawl 42 is

page_text: released from pushing the bunter end of the lever R more or less down, the said
lever 43 is held to the face of the cam 45 by the pressure spring 46 carried in
an inverted pocket and pressing against a lug on the casting.
When the foot of the operator is taken off the starting treadle (not shown)
the shipper rod lever 36, shipper rod T, and wedge will fall by influence of
the spring T and by the lever V with its roll V falling into the hollow N¹ of the
cam N then the horn release pawl finger 41 will push the release pawl 42 (the
latter of which is loosely supported in an undercut groove in the lever 43) down
upon the top portion of the bunter 47, so that when the cam 45 shall push out
the roll 44 with its lever 43, the release pawl shall be in such a position as to
strike the top of the horn cam lever bunter 47 so raising the outer end of horn
cam lever R and with it the rod Q. It will be readily understood that as long
as the foot of the operator is kept upon the starting treadle the roll Vand
lever Vis kept from falling into the hollow N¹ of the cam N, and the release
pawl finger 41 which is in the form of a hook is held by its spring bolt 41 to
the release pawl 42 and keeps it out so that it slides over and misses the horn
cam lever bunter 47.
Before starting the machine it is necessary to adjust the ball collar 35 which
can only be done when the cam-wheel E is turned that No. 1 upon its rim will
be under the pointer 14 and the hand lever 39 turned down inasmuch that at
this point of the turning of the shaft the cam wheel N will assume the position
so that its fullest portion will have pushed out the roller V to its utmost extent
thereby causing the shipper rod lever 36 to move the shipper rod wedge t¹. so
that it pushes the block on to the pulley U which in turn comes upon the cone
pulley 0 The ball collar 35 is then screwed up sufficiently tight upon the
screwed end of its shaft that will ensure the driving of the machine, after said
adjustment the ball collar is locked by the nut 35. If this adjustment was
attempted at any other position of the cam-wheel E the shipper rod wedge fl
might be found too-high for running the machine through the cam N assuming the
position so that the roller V would drop into the hollow N and jam the machine
when said lever was pushed out.
It may be found necessary to adjust the release pawl lever 43 and horn cam
lever Rowing to wear upon the cam 45 so that incre or less tension can be
obtained in dropping the horn post, this can be accomplished by setting the cam
wheel to No. 3 upon its rim under the pointer 14, and turning the eccentric stud
44 Figure 4, Sheet 2 upwards and inwards to tighten, and downwards and out-
wards to loosen it.
When this adjustment is properly made the release pawl 42 should be in such
a position that it can be slid backwards and forwards when or while the operator
is standing upon the horn treadle, when said release pawl 42 will become engaged
with the horn cam lever bunter 47.
To adjust the horn cam lever R to move perfectly free the cam wheel E is
turned so that No. 4 upon its rim will he under the pointer 14, when the pawl 28
Figure 1, Sheet 1, will become disengaged from the rack of the bar P and will
fall upon the stop 31, when in this position the wedge spring T can be properly
adjusted by turning up the adjusting nut To until it just touches the bottom of
the spring when by making four more complete turns sufficient pressure will
be obtained.
In setting the brake 32, the cam wheel E will be set with No. 4 upon its rim
under the pointer 14, the eccentric sleeve 32° Figures 1, Sheet and Figure 3,
Sheet 2 is moved up or down so that the said brake is brought to a proper
bearing upon the coned pulley 0, the check nut on the brake rod 32ª is also
loosened until it is found that the brake lever cam roll V is clear one thirty
second of an inch from the cam N, and falling in its cut away portion N¹, said
check nut is then clamped upon the rod 32" and the spring is exerting its
full pressure upon the brake. At this point or number the top of the awl H
must stand even with the top of its holder.-Said awl is attached to the lower

page_text: 66
end of the awl bar and operated by the means as described in the former speci-
fication herein before referred to seen in full line Figure 2, Sheet 2 of the present
drawings."
An arrow is marked on the wheel E underneath the dial plate 13 and
its point denotes the direction in which the said wheel is to be turned to bring
the figures on the rim of the wheel E up under the pointer 14 which is secured
in front of the top casting and driver slide H in the machine head.
In carrying the before mentioned instructions into execution the hand lever 39
"Figures 3 and 4, Sheet 2" is raised to the position shown in those figures so
that the shipper rod T and wedge are dropped to allow more play between the
driving cone and coned pulley O, and when the operator turns the machine
round by a suitable tool, that even if the cam N touches the roller V it will
not raise the end of the lever 36 sufficiently and thus would prevent the machine
shaft from making a full revolution, were it not for this it would be impossible
for the operator to stop the machine or set it at the numbers marked on the rim
of the cam wheel E.
The throat I is double only when square wire is used and solid when round
is used, and adjustable on end of slide and fully described and illustrated in the
former specification hereinbefore twice referred to, said slide moving to and from
the knives, driver and driver slide H and upon the presser foot 15, backwards
& forwards the latter secured so that the right angled part comes directly under
the throat and awl (see Figure 1, Sheet 1 and Figure 2, Sheet 2).
The stationary cutter is as usual secured in its casting by the screw nut h' and
the movable knife cap h by the screw I.-The tipping of the throat I* to receive
the wire from the wire guide 16 without bending or straining it is carried out
and adjusted according to the thickness, size or shape of the wire by the following
means which have been before described in the former specification before men-
tioned with the exception of said wire guide 16, but in order that such operation
may be well understood the working parts are hereinafter recited as follows:-
In the adjustment of the throat I the toothed lever J is in engagement with
the teeth of the throat slide j (Figure 1, Sheet 1) carried in or on the parallel
bed j, said slide lever is hinged to the top casting by the eccentric stud 13°
Figure 1, Sheet 1, and carries near its centre a stud and coned roller excentrically
governed by an outside eccentric 142 secured by locking nut K, the end of such
stud and coned roller being in engagement with the ordinary machine can L,
said coned roller is capable of adjustment and takes up with and is secured by
an adjustable stud. The strap lever k, carrying roller is mounted on the throat
slide and allows of the slide itself to be adjusted and rocked by the strap
leverk being moved by the motion of the cam B. The throat I after being
tipped receives the wire from the V-shaped wire guide 16 before the knives cut
it ready for the driver to force it cut of said throat into the material. The throat
wire guide 16 is formed with a vertical hole therein to admit of the wire and the
stem thereof is fitted in a block and horizontal slide placed in the stationary knife
casting. When said throat slide j is in the rocking position the throat wire
guide 16 is moved forwards by the point of a circular tappet sleeve formed upon
the solid throat shaft (not shown) said shaft passing through the throat shaft
slide J and is locked thereon by means of a taper screw at j screwed into the
hollowed end of- said shaft, which expands it.
Pivotted at 18 upon the head of the machine is the guard bracket 22 at the
bottom of which is the block 17, in the back of which is a groove 17ª
** dotted
line, Figure 1, Sheet 1," in which fits the uper turned in end of the edge
gauge 19 held therein by the curved ended spring 19 Figure 2, Sheet 2 said
gauge being adjustable backwards and forwards in the groove of said block by
changing the position of the hand lever 19, said hand lever is secured to a boss
having on its under side a hole drilled excentric to the centre of the boss or stud,
said edge gauge 19 and spring 19 is secured to the excentric hole by the screw 196
Figure 2, Sheet 2, said spring 19* thereby causes friction and also prevents the

page_text: operator when working from being able to force back said gauge 19ª, such move-
ment being as above-stated being made by the hand lever 19 screwed to its boss
by the screw 19°; the extent of movement of said hand lever is determinable
by the stop cam 20, striking the top peg 21, fitted in the block 17; by this
arrangement the fastenings are placed at the proper distance from the edge of
the sole, the whole apparatus being turned down out of the way when it is desired
to quilt a sole central. When the bracket 23 is in the horizontal position it is
held up by the spring bolt 18b resting upon the flat side of the projection 18°.
For instantly changing the size of wire and obtaining access to the driver and
wire guide, or to provide a safety guard in case of the driver breaking and flying
in the face of the operator the hinged spring pressed door 23 is employed
screwed to the front casting, (the spring 24 being seen in Figure 2, Sheet 2) and
closed during the working of the machine. In obtaining a more or less throw
of the awl H the same means are employed as described in the former Specifica-
tion No. 14970 of 1896, by an awl feed rocking lever slide fitting in a bracket"
on the driving shaft and at the rear thereof is a split socket centrally bored to
receive a fluted pin or toothed stud which when turned, by aid of a wrench or
the like becomes inserted and engages with a toothed block sliding vertically
in the upper bracket immediately over the stationary knife casting. In adjusting
said awl H the lever and roller m in the bearings m* Figure 1, Sheet 1 is employed
in conjunction with the rocking lever M', the roller of m is in engagement with
the outer groove in the front face of the cam wheel B, the stud of the lever being
eccentric allows it (the lever) to be adjusted accordingly.
The clutch pulley mechanism for rotating the driving shaft at desired times
and the devices for controlling the same and employed in the present machine
is also referred to in the former Specification No. 14970 of 1896.
The column of the machine is of the well known " rapid-standard type," and to
put an upward pressure upon the horn post ordinary well known contrivances are
used, but in dropping the horn after the heel or sole of the boot or shoe has been
operated upon without the operator having to depress the horn treadle the fol-
lowing contrivances are employed; The horn treadle is balance weighted and
centrally pivoted at near the bottom of the column (not shown) to a pivoted
lever, another lever is also connected to the same pivot one end of which is
attached to the bottom of the horn post and the other end to the lower end of
the adjustable rod P, and secured to the toothed slide or rack 24
carried in the bearings 25 Figure 1, Sheet 1." The other slide 26 is
also carried in said bearings and carries in its central arms the hinged pawl
or ratchet 28. The top of the slide 20 is secured to the lower end of the con-
necting rod Q, the upper end of which is attached to the cam lever R which
engages the lifting cam 2. When the lifting action of the latter takes place the
ratchet 28 takes in the teeth of the rack 24 and the horn drops and relieves the
work on the horn from pinch and also allows the awl to carry the work along
freely. Without this the work would be carried along under pressure.
The cap 29 on the bottom bracket 30, the latter cast with the column, carries
the releasing stop 31 which is capable of being adjusted longitudinally and give
the rack slide a more or less lift. To ensure the pawl 28 immediately engaging
the rack 24, upon it leaving the stop 31 in its upward motion; the plug 28" on the
top link of the ratchet 28 is pressed by a spring immediately above it in the
bracket of the slide 26, see dotted line Figure 1, Sheet 1." In its downward
motion the ratchet 28 comes in contact with the stop 31 and by reason of this
it is thrown out of engagement with the rack 24-the horn can thus be raised or
lowered as desired.
6
It will be understood that when the ratchet 28 engages the rack 24 the rod P
will be lifted which also raises the lever to which the bottom end of said rod
is connected, and this lever being pivoted, as before-described in the centre, that
end secured to the horn post must naturally drop and dip the horn.
The brake cam N on the front of the cam wheel O has upon its back surface

page_text: the driving cone 0* its coned outer edge being covered by the strap 32. The full
side of the said cam N ensures the roller V being kept pushed out and the lever 36
to be held up and taking with it the shipper rod T and shipper rod wedge t¹ and
by means of the wedge block pushing against the driving pulley U on to the
cone 0 until such time as the cut away portion N₁ of the cam N is coming
round to the roller V, but so soon as the cut away portion N¹ of the cam N
reaches the roller V the shipper rod T is lowered and through the coupling rod 32"
the brake strap (which is in two parts) 32 and 32 and V shaped on its inner
surface, is pulled down upon the brake cam wheel O, by adjusting the four cheek
nuts seen in Figures 3 and 4, Sheet 2, upon the screwed end of the coupling
rod 32ª.
After the work has been completed on the machine and fresh work is intro-
duced and the operator depresses the foot treadle to start the machine the brake
strap 32 and 32 is released from the brake cam wheel O and the driving pulley U
is again brought into contact with the driving cone Ox and kept in this position.
The wedge block 2, Figure 1, Sheet 1, and Figure 3, Sheet 2, is mounted on
the driving shaft its outer face or incline fitting that of the fork or shipper rod
wedge t, said block is provided with ball bearings, dotted line Figure 1, Sheet 1,
ball bearings 33 are also carried within the ball collar 35 adjustable as before
stated upon the outer screwed end of the driving shaft and locked after adjust-
ment by the screw nut 35* the object being to obviate friction not only in starting
but in running the machine. An oil can stand or holder 48 is formed with the
head of the machine and carries a clip ring 49 to hold the oil can in place for
lubricating the machine. For quilting the sole or fore part of a boot or shoe
with slugs we employ the quilting table 49 as seen in Figure 5, Sheet 2 which
has the stem 49", fitting in the split socket 55, half of which clamps the horn
post 49 which is fitted into the frame W of the machine. Upon the quilting
table is placed the grooved side of the quilting plate 50 one pattern of which
is shown with reference to Figures 54, Sheet 2, 5", Sheet 3 and 5º, Sheet 4 of the
accompanying drawings, the two latter being drawn to nearly full size. The
pins 50 and 50 have flutings or the like at bottom which engage with those of
the fluted bolt 51, like a rack and pinion the end of which carries the lever 50°
used for raising the said pins, the other end of the bolt is secured by the nuts 52,
the spring 525 keeping the bolt from slipping. Within the oblong slot 53 is
the block 54 secured by screws to the stem 49" which keeps the table 49** from
moving round or sideways. The spring 54 keeping the table 49** well up to
the presser foot 15. In putting the above in operation the two pins 50 and 50b
are raised the height desired, by turning the handle 50°, the grooved face of the
quilting plate 50 is placed therron, the inside track being on the pins, the reason
two pins are employed being that if only one was employed the plate would
simply revolve and not travel along to complete the whole surface of the plate.
This latter result is obtained by the awl penetrating the leather fixed on the
quilting plate, and pushing it forward and carrying the plate with it.

To slug the top piece" of a heel of a boot or shoe while still upon the last
a jack is employed capable of a universal movement held in a bracket and fitted
upon the horn post 49* fitted in the frame W. To suit the various sizes of men's,
women's and childrens goods different sizes of jacks are employed.
The jack rod 50* Figure 6, Sheet 2, is carried upon the lower extended portion
of the split holding bracket 51* fitting and clamped to the horn post 49*. In the
said bracket is inserted the vertical spindle 51b carrying the coiled spring 51°,
the upper end of said spindle being screwed into the block 51b said block forming
the internal circular part of the upper cam race 60. The handle 51' of the lower
cam race 51° carries an horizontal spring bolt and trigger 518 when said bolt is
in engagement with one of the grooves in the disc 56, (the latter formed with the
holding bracket 51") the jack rod 50* is held firm at the height according to the
height of the heel, such height is regulated by moving the handle 51' to the right
or left as the case may be. The jack rod 50* works forwards and, backwards

page_text: from the guard plate, or foot 15 on the pivot 57 in the top casting 58, the curved
base of which is serrated and fits upon other serrations 59 on top of the bottom
block 60. A side rocking movement is obtained by the top casting 58 being
swivelled upon the pin 62. The last peg 64 rocks upon its excentric pivot 61
and the curved bottom of the rocking joint is serrated, and is held secure at the
desired angle by means of the excentric pivot 61. The last peg 64 can be taken
out by releasing the blade spring 62.
Another type of jack is shown in Figure 7, Sheet 2 in which the jack post 63
carries in its outer end the spring pressed last peg 64, which keeps the last up
to its work when the horn dips. The lower end of this jack post is swivelled on
to the pin 65 but owing to the lips 66 striking the centre pin 65, the jack-post
is prevented from falling further in its side movements. The nose or stop 68
on the holding bracket 68 keeps the jack post from falling backwards. With
reference to the table jack 69 shown in Figures 8, 8 and 8, Sheet 2 this is
capable of a universal movement to and from; or round and about the guard
plate, or presser foot 15 when presented thereto at any desired angle or pitch of
the heel in which the latter may be required to be held by the operator and is
arranged in the following manner. The last peg is inserted in its block 69* and
rocks on its bearings 69b, and is prevented from rocking too far by the pin 69" in
slot 69, the curved base of the block is serrated and fits in corresponding serra-
tions in the stationary block 69° this is dropped into the hollow block 69d and
held up by the spring 70 which rests upon the divided boss 71 Figure 8' to
keep the teeth apart until pressure is applied, said spring also keeps the blocks 72"
and 72° apart likewise. The serrations when in contact upon pressure being
applied also keeps the last peg from slipping when the heel is held in the desired
position, the flanged collar 70 is placed upon the stem of the hollow block 69d and
is under pressure of the spring 70 thus keeping the serrated parts from jamming,
the lower part of the hollow block 69d is flat on its sides and fits within the
lugs 71 formed upon and with the movable table 72, and pivoted thereto by the
peg 72. The lower part 72ª of the hollow block 69d is serrated and has stops
at each side which come in contact when rocking upon the fixed block 72d, thus
checking any further side movement, corresponding serrations 72° are made in the
base plate 72 which is screwed to the movable table between the lugs 71, said
movable table 72 is provided with the oblong slotted tail piece 73 moving upon
the screw or pin 74 secured in the arm 75 of the stationary table 69, the lips 75"
keeping the tail piece from moving too far in its side motion.
Other patterns or arrangements of the grooves of the quilting plate 50 can be
made than that shown in Figure 5ª Sheet 3, and different sizes employed for
the various sizes of goods made. In order that when the slug is driven into the
top piece of a curved or hollowed out heel, and that it is turned towards the
centre of the heel the bevelled guard plate 15* Figures 1 and 1º, Sheet 1 is
fastened by screws to the presser foot 15, the centre right angled hole coming
immediately under the throat and the awl to allow the awl penetrating, the slug
being driven into the leather.
In quilting
a flat guard plate is substituted for the bevelled one 15*, and
having the right angled hole in the centre for the purpose above mentioned.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:
