PROVISIONAL SPECIFICATION left by the said William Robert Lako
at the Office of the Commissioners of Patents, with his Petition,
on the 9th April 1874.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare thó
nature of the said Invention for "IMPROVEMENTS IN MACHINES FOR SCREWING

page_text: THE UPPERS TO THE SOLES AND HEELS OF BOOTS AND SHOES, AND FOR UNITING
BELTS, HOSE PIPES, AND THE LIKE," a communication, to be as follow:-
•
By this Invention the sole is united to the upper in the manufacturo
of boots and shoes by means of screws cut upon and from a continuous
wire carried by a rotating pressing spindle, in which during tho
cutting of the screw it is at the same time inserted into the material to
firmly unite the pieces, and then severed from the wire. These several
operations are performed automatically in an organized machine, in
which each successive step in the operation (except the rotary motion of
the screwing spindle) is performed by devices actuated by a cam shaft,
each revolution of which causes the complete operation required for the
several purposes stated, while the motions of the cam shaft and the
screwing spindle are continuous during the operation of forming and
entering successive screws; and their length automatically regulated to
the varying thickness of the material by means of an excapement or
tripping device operating in connection with the feeding clamp; while
the feed of the wire is effected by combining with the screwing spindle
a clamp sliding upon and independently of the movement of said
spindle.
The reciprocating clamp is arranged in combination with a spindle
having an axial and revolving motion. I combine with the sliding
clamp head, clamping jaws, toggle pins and a screwing spindle. I pro-
vide a lever device or its equivalent for operating the said clamping
device, and the said clamping device and its operating lever device are
combined with an arresting device for releasing the wire from the clamp.
The said arresting device is arranged in combination with the holding
and tripping or escapement device for holding the arrester and allowing
it to drop out of the way at the proper times. The aforesaid arrester,
lever, clamp, and nose are arranged in combination with anvils or horns
which clinch the ends of the screws. I use a spring escapement detent
and stop arranged upon the fixed frame in combination with the
screwing spindle and the operating cam upon the pivoted frame for
joint operation to release the said arrester at the moment the wire is
unclamped to determine the length of the screw. Escapement devices
and a weighted arm are employed for bringing up the said arrester and
locking it with the escapement detent simultaneously with the descent
of the spindle. An adjustable connecting rod and a cam are arranged

page_text: .
arrester.
The screwing spindle, its clamping device and the lever which
operates it, the aforesaid arrester and its escapement device, the pressing
nose, and the cut-off for the screw are all carried by and arranged upon
a pivoted frame, and have their several and distinct movements produced
from the cam shaft automatically and in their respective successive
relations to each other.
I combine with the reciprocating frame with the oscillating pivoted
frame and the treadle to effect the automatic pressing and holding action
of the nose upon the stock. The spindle for rotating the wire is combined
with a lover connected with the escapement device, tho wire clamping
device, and a screw cutter, whereby the screw thread is cut and the
screw inserted by pressure applied to the spindle. A lever is arranged
in combination with the cam shaft for operating the cut-off and the
shoe-feeding device.
I arrange removable or extensible and beak-shaped anvils for use
separately. The beak anvil is pivoted to its carrying arm, and arranged
to be turned back out of the way of the nose. The said anvil is also
arranged upon a support, that turns around the axis of the other anvil,
so that the face of either anvil for the time being in use shall be in the
line of the axis of the screw that is being screwed into the work. The
said beak anvil is arranged in combination with a foot adjusting screw.
It has a socketed stem in combination with an extensible post and a
removable supporting pin.
By the above description it will be obvious that the work supporting
horn or anvil is in combination with mechanism which operates to
screw the screws into the soles by pressure upon the screwing spindle;
and that the wire feed mechanism gripes the wire automatically and
carries it down for the insertion of a new screw. The pressing nose is
combined with mechanism which operates by reason of any change in
height at which the pressing nose rests on the stock to automatically
cut the wire from the material supplied for that purpose to a length
proportioned to the thickecss of the work at the place where the pressing
nose operates.
It will also be seen that I unite the soles and uppers of boots and

page_text: the screw, pressing the point of the wire just to the inner sole, and
then by contact with the boot and shoe support causing the cutting
off of the wire or severing the screw at the outer surface of the outer
.solc.
An adjustable stop is arranged in combination with the treadle rod
and treadle for regulating and limiting the descent of the aforesaid nose
and shifting the driving band at the same time for operation, as
described. The said nose is provided with removable plates. The cutter
for severing the screw has an adjusting screw and nut. A brake is pro-
vided to act in combination with and arranged to be operated by the
aforesaid oscillating frame.

filed by the said William Robert Lake in the Great Seal Patent
Office on the 9th October 1874.

PROVEMENTS IN MACHINES FOR SCREWING THE UPPERS TO THE SOLES AND HEELS
OF BOOTS AND SHOES, AND FOR UNITING BELTS, HOSE PIPES, AND THE LIKE,"
a communication to me from abroad by John Mundell and Edwin
Francis Partridge, both of Philadelphia, Pennsylvania, United States of
America, Boot and Shoo Manufacturers, upon the condition (amongst

page_text: others) that I, the said William Robert Lake, my executors or admi-
nistrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming part of this Specification :-
By this Invention the sole is united to the upper in the manufacturo
of boots and shoes by means of screws cut upon and from a continuous
wire carried by a rotating pressing spindle, in which during the cutting
of the screw it is at the same time inserted into the material to firmly
unite the pieces and then severed from the wire. These several
operations are performed automatically in an organized machine in
which cach successive step in the operation (except the rotary motion of
the screwing spindle) is performed by devices actuated by a cam shaft,
each revolution of which causes the complete operation required for the
several purposes stated; while the motions of the cam shaft and tho
screwing spindle are continuous during the operation of forming and
entering successive screws, and their length is automatically regulated
to the varying thickness of the material by means of an escapement or
tripping device operating in connection with the feeding clamp," while
the feed of the wire is effected by combining with the screwing spindle
à clamp sliding upon and independently of the movement of said
spindle.

cut-off for the wire and the feed device for the shoo.
.
Figures 8 and 9 are bottom and sectional views of the pressing
nose.
Figure 10 shews the band shifting device of the treadle.
Figure 11 shows a portion of Figure 2 detached.
Upon a fixed standard A a horizontal frame B is pivoted at A',
Figure 2, and arranged to carry the several operating parts of the
machine. The spindle C forms the guide for the wire a and is mounted
in a guide head Cat the front of the pivoted frame B, and it has a
rotary and axial movement to form the screw upon the wire and screw
it into the material. The said spindle carries at its lower end an
automatic clamp for laying hold of the wire to cut the screw and screw
it in; and the fixed frame A carries a device for automatically releasing
the clamp after the screw has been entered. In the combination of the
pressing screwing spindle with the clamp slide D, the latter is free to be
moved up and down upon the spindle; and the clamping devices consist
of two steel jaws b, b, fitted upon toggle pins c, c, to slide within
openings in the spindle, and so as to be closed upon and clamp the wire
within the spindle, the toggle pins being socketed in the jaws and
adjusting screws d, d, in the ends of the clamp. The forcing down of
the clamp straightens the toggles and clamps the jaws against the wire
to be fed down, as shown in Figure 4, and the upward movement of the
clamp flexes the pins c, c, to release the jaws and. tho wire, so that the
spindle with the jaws can rise freely over it to take a new feed, as shewn
in Figure 5. This clamp is moved between an upper and a lower
automatic device which servo to control its reciprocating movement
above stated. The clamping of the wire holds it firmly while cutting
the screw and inserting it into the sole, and the clamp head revolves
with the spindle by its jaw and pin connection.
The clamping movement is effected by a lever E, Figures 2 and 3,
mounted in the pivoted frame B, so that its front forked end will straddle
the spindle above the clamp; while its rear end E¹ extends back to
receive the action of a cam E² on a cam shaft F carried by the pivoted

page_text: frame, and each revolution of the cam E2 will depress the lever E and
force down the clamp to bite the wire to form and enter each screw.
The spindle is suspended by a swivelling connection Cs with horizontal
arms G, G, mounted upon a rock shaft G¹ operated by an arm G* which
receives a vibratory motion from a groove cam H, Figures 7 and 11,
upon the face of a cog wheel H' on the cam shaft F, whereby the
spindle is carried down and raised, the cam being such that the descent
of the spindle is gradual to screw in the screw, and commencing just
after the wire is clamped; and its ascent takes place just after the screw
is entered and the wire cut; while the rotary motion of the spindle to
cut and screw in the screw is produced by a sleeved pulley I driven
continuously by a band I leading to a pulley I on the power driving
shaft I at the rear of the frame.
The sleeve v, Figure 3, of the pulley I is secured in the guide head by
a collar w and a screw a passing through the collar and the sleeve enters
a groovey in the spindle to allow the latter an axial pressing move-
ment while being revolved. The nose K projects forward from the
under side of the pivoted frame B, and during the above stated operations
of the spindle the nose is brought down upon and firmly holds the work
upon a beak iron or horn L, Figure 1. This nose carrics both the screw
chaser and the cut-off for the wire.
The unclamping movement is effected by a forked gauge or arrester M,
Figures 2 and 3, mounted upon a rock shaft M' in the fixed frame and
held in a fixed position between the clamp slide and the nose K, to serve
to arrest the descent of the clamp slide and release the jaws b, b, while
the spindle continues its descent to the full length of its movement,
which must be sufficient for the longest screw required; the arrester is
tripped in this movement of the spindle and descends with it.
The device for holding and tripping the arrester M consists of a stop
projection M², Figure 6, on the left end of the rock shaft M', and which
stop is held in its fixed position by a spring detent e carried by an
arm e' pivoted upon the fixed frame and connected by an adjustable.
link N to an arm N' upon the rock shaft G¹ which elevates and depresses.
the spindle through the cam H. The arm N¹ must be of the same
length and in the same radial position or nearly so as the arms G of the.
spindle to insure an equal movement of the detent arm c¹ with that of
the spindle carrying arms. The detent e is a spring plate having its.

page_text: acting end in the form of a segment e² of a circle whose centre is tho
axis of the detent arm e', and the stop projection M² has a flat side for
action against the segment e³, so that when the spindle and the arrester
have descended a distance equal to that between the nose K and the beak
iron L, plus the projection of the screw after it has been entered and
clinched, the stop projection M² will at this moment pass the angle 2 of
the segment detent e, and thereby allow the arrester to be free to
descend with the spindle, as stated. After this full movement the
spindle is brought up by the cam H, and the arrester M is caused to rise
and bring up the clamp, and to resume its fixed position by an
adjustable weighted arm f, Figures 1 and 6, secured to the rock shaft M'
and extends backward to constantly exert its force to bring up the
arrester, which thereby carries the escapement projection M² past the
angle 2 of the detent e, which being a spring plate yields for that pur-
pose and allows the projection M² to again rest against the segment e³
and hold the arrester in its fixed position. The arrester follows tho
clamp slide up and down, the action of the escapement projection
causing a hesitation in the downward movement of the arrester at the
proper point to relieve the clamp. In Figure 6 the parts aro in tho
position they occupy just at the moment before the escapement takes
place at the point 2, while the dotted line 3 shows the position of the
detent e while holding the arrester M to act upon and release the clamp-
ing device; and the dotted line 4 indicates the point to which the
detent is carried after the escapement, and while the screwing spindle is
making its full descent, and for determining the accuracy of the required
adjustment of these parts, the stop M² and the connecting rod N are
made adjustable. The detent arm e¹ has a movement due to that of the
tilting frame B, and also a movement due to the action of the arm N¹
upon the rock shaft G', the result of which is, that in proportion as tho
nose K approaches the beak iron L, governed always by the thickness of
the material, the spring detent will approach the point at which the
escapement may take place, consequently if the material be thin the
points of escapement will have been more nearly reached or closer
together than when a greater thickness of material is under operation.
For example, if the nose approaches the beak iron an eighth of an inch
then the spring detent arm e¹ will be in that position that an eighth of
an inch movement will bring the detent at the point of escapement.
In this movement the arm N' and spindle also descends the same
distance, and the spring detent e will be at the point 2 to allow the

page_text: projection M to pass it and free the arrester M, to be depressed out of
the way. By these means the arrester forms the gauge that regulates
the lengths of the screws for the different and varying thicknesses of
the work, such as the shank of the shoes, which requires a shorter screw
than the sole, and also for different thicknesses of solos. It is by the
joint action of the lever E in the pivoted frame B to clamp the wire
at a point with reference to the movement of said frame, and the
arrester M having a fixed position with reference to the fixed frame,
the beak iron and the nose, that any variation in the distance between
the nose K and the beak iron L will produce the same variation in the
distance between the arrester and the forked lever and determine the
length of the screw.
By adjusting the height of the beak iron, with respect to the nose K,
the screws may be screwed partially through the material and not
clinched and their full length always obtained, besides the surplus end left
in the cavity g of the nose. The nose K is brought into position over
and near the material upon the beak iron L by a treadle O pivoted at
the base of the frame, and acting through a rod O¹ to depress the front
end of the pivoted frame which carrics said nose. This action of the
treadle O at the same time shifts the driving belt from a loose pulley /
to a fixed pulley ¹, Figure 10, upon the power driving shaft I³, and
thereby revolves the spindle and puts in motion the operating mechanism
in the pivoted frame, the band shifter being pivoted upon the fixed
frame and connected to the treadle rod O! by a rod O provided with a
spring O³, which constantly tends to depress the rear end of the treadle
through an arm O'. A belt P from the pulley P¹ on the driving shaft I³
gives motion to a shaft Q, a pinion R which meshes with the cog
wheel of the cam shaft, and thus automatically operates the several
parts.
Immediately upon the starting of the machine a cam S, Figure 2, on the
cam shaft Facts upon the front end of a sliding frame T mounted upon
a pivoted arm T.. This frame carries a rod U connecting with a cam or
bell-crank lever V pivoted at V2 which acts upon a cam or head piece o³
on the upper end of the connecting rod O¹, a bearing roller V, Figure 2,
being placed between the lever V and the head O³ to relieve the friction
and effect a uniform motion of the lever. This backward movement of
the frame T vibrates the bell-crank lever V to which the rod U is con.
nected; and as the end of the lever V rests, upon the upper end of the

page_text: treadle rod O¹, and as the latter is held up by the foot against a stop j,
Figure 1, which limits the ascent of the treadle rod O' and the point to
which the nose K can be brought down by the foot, it follows that the
rearward movement of the frame T must by the action of the lever V
raise the rear end of the tilting framo B, and thereby bring the nose K
down firmly upon the material; any variation in the thickness of the
latter will be compensated by the yielding of the connecting rod U:
which has a spring attachment with the reciprocating frame T for that
purpose, as shown in Figure 2. The tilting frame B is constantly pulled
down at its rear end by a spring W attached to the fixed frame, and the
reciprocating frame T is constantly pulled forward against its operating
cam S by as pring X attached to the pivoted frame, as shown in
Figure 1. The screw chaser J is made adjustable and is arranged on the
upper side of the nose, which has a vertical opening through it for the
passage of the wire in contact with the screw chaser. The cutter Y for
cutting off the screw is arranged in the under side of the nose in a
slide Z which moves in a groove in the nose piece, and by which the
cutter is connected to a lever k pivoted in the tilting frame and operated
by a cam 1, Figure 7. The stem Y¹ of the cutter has a screw thread,
and is screwed into a nut m, Figures 8 and 9, fixed in the slide Z,
whereby the cutter may be adjusted and removed and replaced when
necessary. The chaser J and the cutter Y are both held within their
respective grooves in the nose by removable plates n and n², for access
to these parts. These plates n, n¹, are secured to the nose by screw
bolts o fitting into notches in the edges of the plates and nose and
clamped by screw nuts o', so that slackening off the nuts the bolts and
plates can be easily removed when anything is required to be done to
either of the cutters, and the several parts replaced.
Two anvils are used for supporting the heel or the sole, as may bo
required.
The anvil or beak iron L is arranged so that its acting point L' will
fall in the range of the screw when in position for use. It is pivoted at
its lower end so as to be turned back upon a horizontal arm I fixed
upon a vertical stem L³ mounted in guide bearings 1, ', in the fixed
frame, and upon which stem L³ the beak iron and its arm L is free to
be swung round horizontally as the work progresses. The beak iron L.
has a branch arm by which it is supported, and is adjusted by a.
scrow in the arm L', in which adjustment the anvil turns upon a.

page_text: pivot, so as to raise and lower the acting point L' with respect to the
nose. This pivoted anvil or horn is for use in screwing on the soles, and
being of metal clinches the inner end of the screw when the latter
strikes it as it is screwed home. The anvil L is turned back out of the
way upon its pivot when the sole work is finished, and the heel portions
of the soles are supported for operation by a post anvil p which fits
loosely within a deep socket in the vertical stem L³, and which is
clevated and held within said socket at the proper height by a pin p
passing through the stem at på beneath the post; or any other suitable
device may be used for this purpose when the post anvil is subtituted
for the horn anvil and the two have the same axis. The stem L' is
adjustable by a screw L' and lock nuts at its lower end, for effecting the
proper adjustment of the anvil with respect to the nose.
A feed arrangement for boots and shoes consists of a roughened
roller q supported upon a spring arm q' from the fixed frame just
beneath the nose, so that the edge of this roller will press upon and by
its intermittent motion feed the work along, while it also serves as a
guage to determine the distance of the screws from the edge of the sole.
This is done by the operator pressing the sole against the roller, and tho
latter is operated by a ratchet q² and a pawl q³, and the latter is operated
to produce this feed by the back stroke of an arm k², Figures 2 and 7,
of the same lever / which operates the cutter slide, so that the feed
of the work shall take place just after the entered screw has been
severed and the nose is raised. The lever k is kept in position for the
action of the cam by a spring in any suitable way which constantly
draws the lever forward and the knife back.
When the work upon the soles from shank to shank is finished the
machine is stopped by removing the operator's foot from the treadle O,
which instantly shifts the driving band by the shifter i from the fixed
to the loose pulley.
The momentum of the shaft I' and its pulleys tends to continue the
motion of the working parts a little, and to avoid this I employ a
brake pivoted at s to the tilting frame, in a position to bear upon the
pulley I and to stop the machine, as shown in Figure 2. The brake is
adjustable by a screw È in an arm u, and its capacity to stop the
machine is derived from the movement of the frame B, which upon the
full descent of the rear end of the frame B brings the braker down
upon the pulley I² and instantly stops it. The depression of the nose K.

page_text: by the foot to the limit of the treadle stop j instantly raises the brako
and releases the driving pulley 12, and in this way the tilting movement
of the spindle carrying frame is utilized to put on and take off tho
brake.
The movement of the pivoted frame must have a certain exactness
with the action of the escapement devices, and for obtaining such exact
adjustment the rod N which connects the two things is provided with
a proper screw connection, as shown in Figure 6. The screw is cut
with a divided or notched end to clinch it when enterod against the
anvil.
In operating the machine the treadle O brings the nose K down near
the sole but not upon it, the stop j preventing contact, and this
movement simultaneously shifts the band from the loose to the fixed
pulley ', and the screwing spindle C'and cam shaft F are set revolving
by the bands I and P, Figure 2. The cam S acting upon cam V
through the frame T lifts its rear end and depresses its front end hard
upon the sole, in which position it is held by the concentric portion of
the cam S, while the spindle is carried down by the cam H through the
connecting arms G, G³, and with it the clamp D to clamp the wire which
is forced into the opening in the nose and has the screw thread cut,
the spindle continuing its descent and revolving screws the screws into
and through the material and against the anvil. At this point the
clamp D has pressed against the arrester M sufficiently to release the
jaws d, unclamp the wire, and set the arrester free by the spring detent e
passing the stop projection M² which in the meantime was operated by
its arms e', N, N', connecting with the spindle driving rock shaft G'.
The arrester descends clear of the clamp D and the spindle continues
the remainder of its stroke idly, the last motion being required for the
greatest possible length of screws. At this point the cam S has passed.
its concentric surface, and allows the rear end of the tilting frame B to
drop and thereby raise the nose from the sole.. The cutter is now driven
forward by the cam and lever k and cuts off the entered screw; tho
back stroke of the lever k acts through the ratchet q² and pawl q³ to
operate the feed, wheel q and move the sole to receive the succeeding
screw. Both sides of the shoe are screwed from shank to shank, the
beak iron anvil being swung round to turn the toc.
The machine is stopped by removing the foot from the treadle and
bringing the brake into action.

page_text: In working upon the heel portion of the sole the beak iron is turned
back, as shewn in dotted lines in Figure 1, and the stem post p raised
and supported in its socket at the proper height, and the heels are now
secured in the same way as the soles, the heels being the heel portion of
the soles and not the high heels; and the curved end of the beak iron is
not so well adapted for work on the heels as the post anvil.
The method of feeding the wire and the automatic device in con-
nection therewith enables the extent of feed movement imparted to
the wire to follow the minutest changes in thickness of the parts to be
united.
