Year: 1875

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lako, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVEMENTS IN MACHINERY FOR MAKING HORSE-
SHOES. ."-A communication from abroad by Jacob Russell, of the
City and State of New York, United States of America, Gentleman.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 5th January 1875.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR MAKING
HORSE-SHOES," a communication, to be as follows:-
The blanks for the bending and pressing machine are produced in a
separate rolling machine which produces continuous bars having the
› requisite creases and also marks to indicate the proper length for cach

page_text: shoe upon them, the creasing and marking being done at the last pass
that the bar of iron makes through the rolls. I mention this simply to
have it understood that my machino does not do this work.
One object of my improvements is to effect the thinning of the inner
_edge of the shoe at a stage of the operation when only the outer edge or t
side of the shoe is sustained by the upright walls, and thus render it
practicable to press down the inner edge of the shoe to almost a knife
edge, if such degree of thinness is required; and another object is to
effect the pressing of the shoes in a female die which has a gradual taper
upward, and at the same time to be able to discharge the shoe automatically 1
from such a die, this manner of pressing the shoes allowing me to make
them with an inward draft or narrower at their base than at their top,
and thus produce shoes which will not cause the feet of horses to
interfere.
And another object of my Invention is to effect the proper feoding, 1
and cutting off, and supporting of the iron while the machine is in con-
tinuous operation.
Another object is to effect a compression or "upset
"of the ends of
the pieces of iron of which the shoes are formed by the shears which
cut off the iron and thus increase the density of the heel ends of the 2
shoes.
The nature of my Invention consists in the means hercin-after set
forth for accomplishing the objects above specified.
To one side of the frame of the machine a bracket is slotted vertically,
and in the slot of the bracket a sliding frame carrying the pawls is fitted
to slide back and forth. These pawls are on vibrating shafts which are
geared together by small pinions. The guide of the frame is connected
to a spiral spring which is fastened to the bracket. Another set of pawls
is applied on the bracket, but they do not slide nor are they geared
together, but simply attached to vibrating shafts of the bracket and held
together by a spiral spring. On the shaft of the lower one of the sliding
pawls a trip arm is fastened, and it hangs pendant from the shaft of said
pawl. At the rear of the said bracket another bracket is bolted on the
frame, and in this bracket a clutch shaft is fitted to revolve. The parts
of this shaft are connected by a sliding clutch which is operated by a
clutch lever. On the front end of this shaft a plate with a crank pin or
roller set in it near its circumference is applied. On the rear end a

page_text: small level pinion is applied, and this pinion gears with a level wheel
on the back. shaft of the revolving rolling die of the machine. The
sliding pawls take hold of a bar and move it just the length required
through and past the shears.
5 The shears are formed of two pieces pivoted together and adjustably.
bolted to the frame. One jaw of these shears is stationary and the other
movable. The movable jaw has a lever extension formed on it which
rests upon a cam portion of the said back shaft, and this jaw is opened
and closed twice during the revolution of the shaft by the cam pro-
0 jections on the shaft. On each side of the cutting edges of the shears
a broad level surface is formed for the purpose of squeezing or upsetting
the ends of the metal during the act of cutting off the lengths for the
horse-shoes.
'
.
Three disc rollers which I term the first, second, and third rollers
5 revolve with geared shafts. Two rests are provided for the support of
the lengths of iron which are cut off from the bar. Side levers which
have friction rollers on their front ends are placed just in rear of the
rests and in close proximity to the sides of the first roller. These
levers are pivotted to the top of a standard or pillar of the frame
and vibrate laterally in a horizontal plane. The rear ends of these levers
extend back and over the back shaft and bear by means of friction
rollers on their under side against notched cam rollers which give to
their front ends a movement corresponding to the outside of a horse-
shoe. The said first roller is constructed with one or more male dies
which in outline correspond. to the horse-shoe to be bent and pressed.
Through the top of each of these dies a slot is cut down to a proper
depth, and in this slot the guide and support of a sliding horse-shoe
iron former of semi-eliptical shape is fitted. This former which is,
about half as long as a horse-shoe and somewhat broader than the slot is
fitted upon the outer face of the male die. The said former is properly
shaped to avoid marking the iron. The guiding support of this former
extends from the former along a slot cut in the circumference of the
roller, and is connected by a hinge joint to a lever link which is also
in a slot, and is pivoted at the rear of the hinge joint to the first roller.
On the back of the link a cam projection is formed. The hinge joint of
tho link and guide plays in and out of notches formed on the circum-
ference of the said first roller. The jointed links of the former form a
toggle, and as the joint is depressed the said former_slides in the slot-of-.-
.

page_text: the die. In order to move this former back to its normal position a
spiral spring is placed under the joint of the toggle.
A rolling stop is hung in a stationary bracket of the frame just in
front of the first roller, and about in a plane with its shaft. This roller
acts as a permanent means, whereby the joint of the toggle is depressed
and the aforesaid former is caused to move up against a length of horse-
shoe metal, which is resting in the supports at the moment the die of
the said roller is in the act of beginning to match and enter the female
die of the second of the three rollers. The said second roller is con-
structed with a female die in its circumference. The bottom of this die
has a frog set on it for forming the bevel or concave on the upper side
of the shoe, and the sides of the die cavity are inclined outward so as to
have an under bevel at all points. These sides are formed on laterally
sliding circular collars or flanges having long hubs, which fit upon the
shaft of the second roller, and are kept from turning independently of
the roller by feathers or keys. Through the roller or into each of its
ends spiral springs are placed, and against these flanges are set, and by
means of the springs the flanges are caused to slide when freed from
rostraint. Cam projections are arranged on the frame, and cam notches
are formed in the ends of the hubs of the flanges. When the notches
coincide with the cams the springs are free to slide the flanges, and
thereby open the female die, but when the cams and notches do not
coincide the die is closed, and the springs cannot open them. The
flanges of the female die may slide and expand the die for the purpose
of discharging a shoe that has been bent and pressed by the machine.
The circumference of the second roller is grooved and scored in order to
afford the necessary room for the toggle and projecting portions of the
first roller, and in the cam collars of the back shaft notches are cut in
order to allow the bearing levers to move out of the way when the
widest portion of the male die comes in contact with the rollers on their
front ends. The third roller has a finishing male die or dies upon its
circumference, which exactly fit the female dio, and by means of these
two dies coming together the shoe is pressed as thin as desired on its
inner side, or that side where the concavo is formed, while on the outer
edge the shoe is pressed so as to have when in use an inward inclination
from top to bottom.
The hub of the expansible die has attached to it a segmental or semi-

page_text: axis of the shaft will give a corresponding movement to the die. To
secure this movement there are arranged at each side of the machine in
suitable bearings in the frame two friction rollers at opposite sides of
the shaft, and also at opposite sides of the plane in which the said plates
5 revolve.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent-
Office on the 3rd July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of January, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
cighth year of Her reign, did, for Herself, Her heirs and successors, givo
and grant unto me, the said William Robert Lako, Her special licenco
that I, the said William Robert Lake, my executors, administrators, and
assigns, or such others as I, the said William Robert Lake, my
executors, administrators, and assigns, should at any time agree with
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for “In-
PROVEMENTS IN MACHINERY FOR MAKING HORSE-SHOES,” a communication to
me from abroad by Jacob Russell, of the Oity and State of New York,
United States of America, Gentleman, upon the condition (amongst
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

Figures 6, 7, and 8, are detached views showing certain parts of the
said modifications.
A represents the frame of the machine. To one side of this frame a
bracket A' is slotted vertically, and in the slot of the bracket a sliding
frame carrying two pawls a, a, is fitted to slide back and forth. These
pawls are on vibrating shafts which are geared together by small
pinions c, c. The guide of the frame is connected to a spiral spring d,
which is fastened to the bracket A². Another set of pawls a¹, a', is
applied on the bracket, but they do not slide nor are they geared
together, but simply attached to vibrating shafts of the bracket A², and
held together by a spiral spring a' as shown.
t
On the shaft of the lower one of the sliding pawls a trip arm o³ is
fastened, and it hangs pendant from the shaft of said pawl. At the rear
of the bracket A' another bracket A'is bolted on the frame A, and in this
.bracket a clutch shaft B, B³, is fitted to revolve. The parts of this shaft
are connected by a sliding clutch B', which is operated by a clutch
lever B³. On the front end of this shaft a plate O with a crank pin or
roller c¹ set in it near its circumference is applied. On the rear end a
small bevel pinion d is applied, and this pinion gears with a bevel .
wheel e on the back shaft E of the revolving rolling die of the machine.
:
The sliding pawls take hold of the bar Z, and move it just the length
required through and past the shears. This movement is produced by
the crank pin c" of the plate O striking the trip arm c³ of the lower pawl.
The stationary pawls prevent the bars slipping back while the sliding
pawls are automatically moved back by the spring & for a new bite upon
and feed of the bar forward. The pinions of the pawls keep them in
proper position relatively while making their reciprocations, and they also
allow them to open and close to accommodate the bar. The closing of
and bite of the pawls upon the bar Z is produced just before their forward
movement begins by the contact of the crank pin with the trip arm, and
at the completion of the feed movement of the pawls the gravity of the
trip arm causes the pinion to which it is attached to turn, and thereby
open the pawls and release them from their bite upon the bar Z.
D, D, are the shears formed of two pieces pivoted together and
adjustably bolted to the frame A. a short distance forward of the
bracket A. One jawf of these shears is stationary, and the other f¹
movable. The movable jaw f' has a lever_extension formed on it,

page_text: which rests upon a cam portion g of the shaft E, and this jaw is opened
and closed twico during the revolution of this shaft by the cam projec.
tions on the shaft. The shape of the jaws of the shears is very similar
to the matching teeth of two rag wheels, and on cach side of the cutting
edges h, h¹, of the shears a broad level surface hª is formed for the purposo
of squeezing or upsetting the ends of the metal during the act of cutting
off the lengths for the horse shoes.
F, F, F, are three disc rollers revolving with their geared shafts
G, G¹, E. These rollers are set so that F and F¹ work upon one another
first, and then F' and F' work upon one another. H, H, are rests for 1
the support of the lengths of iron which are cut off from the bar; I, I,
are sido levers, which have friction rollers *, *, on their front ends just
at the rear of the rests H, H, and in close proximity to the sides of tho
roller F, as shown. These lovers are pivoted to the top of a standard or
pillar A' of the frame A, and vibrate laterally in a horizontal plane. 1
The rear ends of these levers extend back and over the shaft E, and
bear by means of friction rollers on their under side against notched cam
rollers i, i, of the roller F, which give to their front ends a movement
corresponding to the outside of a horse shoe. The roller F is constructed
with one or more male dies j, which in outline correspond to the horse 2
shoe which is to be bent and pressed. Through the top of each of these
dies a slot k is cut down to a proper depth, and in this slot the guide
and support 7 of a sliding horse shoe iron former m of semi-elliptical form
is fitted. The former, which is about half as long as a horse shoe, and
somewhat broader than the slot, is fitted upon the outer face of the male 2
die, as shown. This form of former is adopted in order to avoid marking
the iron when it takes hold of it. The guiding support of this former
extends from the former along a slot cut in the circumference of the
roller, and is connected by a hinge joint n to a lever link o, which is
also in a slot, and is pivoted in rear of the hinge joint to the roller F, as 3
shown at p. On the back of the link o a cam projection o¹ is formed.
The hinge joint of the link and guide plays in and out of notches q
formed on the circumference of the roller F. Tho jointed links of tho
carrier m form a toggle, and as the joint is depressed the former m slides
in the slot of the dio j. In order to move this former back to its 8
normal position a spiral spring is placed under the joint of the toggle,
as shown.

page_text: front of the roller F, and about in a plane with its shaft. This roller
acts as a permanent means whereby the joint of the toggle is depressed,.
and the former m caused to move up against a length of the horse-shoe
metal which is resting in the supports at the moment the die of the
roller F is in the act of beginning to match and enter the female die of
the roller. This stop is struck by the cam projection of the toggle link,
and as the cam cannot pass by-it until the spring under the joint yields,
the toggle must of necessity be depressed during the contact of the
projection with the stop, and by this depression the former is caused to
slide inward with great force against the piece of metal, and carry it to.
the too end and bottom of the female die. As the metal is thus carried
forward the side rollers *, *, on the ends of the levers I, I, are caused
by the cams i, i, to move in conformity with the shape of the desired horse-
shoe, and these rollers in thus moving bear upon the iron as it is forced
by the former, and subsequently drawn by the die rollers-into the female
die. The roller. F' is constructed with a female die or dies & in its
circumference. The bottom of this die has a frog t to set on it for
forming the bevel or concave on the upper side of the shoe, and the sides
of the die cavity are inclined outward, so as to have an under bevel at
all points, as shown at u. These sides are formed on laterally sliding
circular collars or flanges F³, having long hubs which fit upon the shaft
of the roller F, and are kept from turning independently of the roller
by feathers or keys. Through the roller or into each of its ends spiral
springs are placed, and against these the flanges F" are set, and by
means of the springs the flanges are caused to slide when freed from
restraint; N, N, are cam projections on the frame A; and N', 'N', cam
notches in the ends of the hubs of the flanges F. When the notches N'.
coincide with the cams N, the springs are free to slide the flanges, and
thereby open the dies, but when the cams and notches do not coincide.
the die' is closed and the springs cannot open them.
.
In Figures 1 and 2 I have shown how the flanges of the die s may
slide and ovnend the dio for the purpose of discharzino a shoe that has

page_text: portion of the male die comes in contact with the rollers on their front
ends.
The roller Fs has a finishing male dio or dies W upon its circum-
ference;) this dio exactly fits the female dies, and by means of these two
dics coming together, the shoc is pressed as thin as desired on its inner &
side, or that side where the concave is formed, while on the outer edge
the shoe is pressed so as to have, when in use, an inward inclination from
top to bottom.
8
It will be understood that the bottom of the dic & is straight, and that
as the back roll travels over the shoo it is pressed down to a straight 1
surface, and is confined under the edge of the die 8, whence it is delivered
when the die W is out of the dies by the notches N', N', coming in a
coinciding relation with cam projections N, the springs being allowed
to expand the dies as before described.
By my Invention I effect four very important objects, namely :—
First. The concave of the shoe is produced and the degree of
thinness is far greater than has heretofore been effected by rolling in
horse-shoe machines.
Second. The outer edge of the shoe is inclined inward.
1
Third. The shoo is turned out straight and there is no necessity for 2
passing it through a straightening process.
Fourth. The shoe being formed in a dio, instead of around a dio, the
heavy fin which presses out at the side of the shoe as heretofore made
is avoided, and the expense of taking it off with an emery whoel is
saved.
The said machine may be operated by a pulley shaft O, on which are
fast and loose pulleys P, P', and a small pinion P³ and a balance
wheel P³. Pinion P³ gears with a master spur wheel Q on the shaft of
the roller F; on the same shaft there is a spur wheel R which gears
with two spur wheels S and T of the same diameter, but these are on the 3
shafts of the rollers F, F, as shown.
Motion being imparted to the pulley shaft, the pinion on it sets in
motion the large spur wheel, and this sets in motion the spur wheel of
roller F, and this wheel in turn sots in motion the wheels of the
rollers F, F, and also the bevel wheel e, and this sets in motion the 3

page_text: pinion d of the clutch shaft on which is the crank plate for operating
the feed.
I have above described- one method of actuating the expansible
dies F³, F', but inasmuch as a positive movement of the said dies in
› each direction is for some reasons preferable to that obtained when the
springs are used, I have provided for use when desired or preferred a
positive mechanism for actuating the aforesaid dies in place of that
herein previously described for said purpose, which positive mechanism
is represented in Figure 5, and in certain details in Figures 6, 7, and 8.
› Figure 5 shows the mechanism upon one side only of the machine, that
on the opposite side being simply a duplicate of the same, so as to secure
the requisite movement to both of the dies.
The hub of the die F has attached to it a segmental or semicircular
plate D, which when moved in or out in a direction parallel with the
5 axis of the shaft G will give a corresponding movement to the die. To
secure this movement there are arranged at each side of the machine in
suitable bearings in the frame A, two friction rollers ≈ at opposite sides
of the shaft G, and also at opposite sides of the plane in which the
plates D revolve. At every revolution of each plate its foremost end or
corner strikes against the rounded periphery of one one of the friction
rollers, which acting as a cam against one lateral surface of the plate
forces the plate inward to close, the die. Afterwards the continued
rotation of the plate brings its opposite lateral or side edge in like
contact with the second friction roller 2, which moves the said plate in
5 the opposite direction as required in opening or expanding the dies to
discharge the shoe.
Figures 7 and 8 indicate the position of the plates D upon cach end
portion of the shaft G to actuate the two halves of the dio F, and the
means that may be used to cause them to rotate with the shaft, while
Figure 6 shows the position of the friction rollers x with reference to
each of the said plates.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,--

combination with the roller F constructed and operating, as herein
