No. 100, Fleet Street, in the City of London, for the Invention of
"IMPROVEMENTS IN HORSE-SHOE MACHINES."-A communication from
abroad by Jehu Brainerd and William Burridge, Consulting Engineers,
both of the City of Cleveland, in the State of Ohio, in the United

COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and Declaration,
on the 30th October 1862, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 100, Fleet Street, in
the City of London, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
HORSE-SHOE MACHINES," and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for the same,
and have made solemn declaration that the same has been communicated
to me from abroad by Jehu Brainerd and William Burridge, Consulting
Engineers, both of the City of Cleveland, in the State of Ohio, in the United
States of America..

page_text: KNOW NOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what manner
the same is to be performed, in an by the following statement, reference
being had to the accompanying Drawings, making a part of this Specification,
in which Figure 1 is a plan view, Figure 2 is a side view, Figure 3 is a side
view of the opposite side shown in Figure 2, Figure 4 is an end view, and
Figures 5, 6, 7, 8, and 9 are sections, which will be referred to in the
description. Like letters refer to like parts in the several views.
The framework, boxes, and other stationary parts are all secured to the bed
plate A. On the main shaft B is secured the revolving eccentric C, to which
is attached the shoe mandril D. This shaft B has its bearings in the boxes E.
To one end of this shaft is secured two cams F, F¹, as seen in Figures 1 and 2,
and to the opposite end is secured a cam G, Figures 3 and 4, which cam is
for operating the cutters or shears for cutting off the bar of which the shoe is
made, as hereinafter described. H represents a bar, which slides in ways
upon the bed plate A and at right angles to and below that end of the shaft B
that carries the cams F and F!. It has two arms I and I' rising from its
upper surface; which. emtrance the cams F and F¹, consequently, by the revo-
lution of the shaft B the bar H is moved back and forth upon the bed plate A
to an extent equal to the eccentricity of the cams. K is a rock shaft. placed
parallel to the shaft B, but at the opposite end of the bed plate; to one end
of the shaft K is attached an arm J which fits into a slot in the bar H, as seen
in Figure 2; thus the rock shaft K is put in motion by the primary action
of the shaft B. L shows an arm which projects downward and forward, as
seen in Figures 2 and 3, from the rock shaft K, to which it is securely
attached, and is moved from L to L' by the novement of the rock shaft K.
The arm L has a secondary arm L" (see Figure 1) pivoted to it at a. It is
drawn away from L by the spring M and connected to a cam lever N by the
rods O, O, which pass loosely through holes in the arm L, then into the
secondary arm L", when they are secured by nuts or otherwise. The cam F
acting on the arms I', and by the intervention of the bar H and arm J the
rock shaft K is so operated as to raise the arm L from its position in Figures
2 and 3 to L', as indicated by the dotted lines in Figures 2 and 3; and by the
action of the cam F¹ on the arm I the arm is depressed to L, Figures 2 and 3.
The secondary arm L" is made to move to and from the arm L by the action
of the spring M and the cam lever N, thus the arm L" has two movements,
vibrating and lateral, while the arm L only vibrates vertically. When the
arm L is raised to L', for the purpose of receiving the partly formed shoe from

page_text: shoes for mules
the mandril D, the secondary arm L" is drawn close to the arm L, as seen in
Figure 5, which is done by means of the connecting rods 0, 0, Figures 1
and 5, and cam lever N in connection with the roller P. The rods O, O, are
pivoted to the cam lever N, which pivot constitutes the fulcrum of the cam
lever. As the arm L is raised the long arm of the cam lever N is brought
under the roller P, thereby depressing the long arm of the cam lever, and as
the arm L rises by this action the short arm N¹ of the cam lever presses
against the side of the arm L, thereby drawing upon the rods 0, 0, and this
brings the secondary arm L" close to the primary arm, as seen in Figure 5,
and as soon as the primary arm moves down so as to relieve the cam lever N
from pressure of the roller P, the spring M, by its action, forces the secondary
arm L" back to the position seen in Figure 1. Into the end of the arms L, L".
is screwed the dies Q, Q, in sections, one half being in each. These dies may
be of various sizes for various sized shoes, those for making
being much smaller than those for making horse-shoes. The screw R regu-
lates the distance the arms L, L", separate. The shoe bar d is fed into the
gauges S, S, as indicated by the red lines in Figures 1 and 4, and cut off by
the cutter or shears T, Figures 1 and 3. The iron (being hot) is then, by the
action of the revolving mandril D upon the eccentric C forced out of the
gauges into the jaws U, U. These jaws U, U, are pivoted to the plate mat
U', U', their form and relation to other parts being fully shewn in an enlarged
Figure 8. The mandril presses upon the heated bar, when in the gauges, in
the centre of it, the bar being so cut and adjusted by means of the stop e that
the ends are equidistant on each side of the mandril D, which prevents one
side of the shoe from being longer than the other in forming. As the iron is
being forced out of the gauges and carried forward to the jaws U, U, it is bent
around the mandril, partially forming the shoe. Directly on leaving the
gauges the partly formed shoe d, Figure 8, enters the jaws U, U, which press
it around the mandril D, as indicated in Figures 1, 7, and 8. This pressure
increases upon the edges of the shoe as the mandril advances with the partially
formed shoe in the jaws which move with the mandril until it has passed the
axis U, U, of the jaws, the mandril passing out from between them, the
springs V, V, moving the jaws back to their original position, as seen in
Figure 8. The mandril, on leaving the jaws, carries the partly formed shoe
forward to the dies Q, Q, in the ends of the arms L, L", which are raised to
the exact position to receive the mandril and partly formed shoe. The position
of the mandril with the shoe c in the dies Q, Q, is shewn in Figure 6. In
this position the shoe is completed by being pressed between the male and
female dies into the desired form, as seen in Figure 6. The pressure upon

page_text: the shoe increases from the moment the mandril enters between the jaws until
the extreme circumference of the eccentric C, upon which the mandril D is
placed, passes the axis of the rock shaft K, then, by the action of the spring M,
the arm L" moves back, as seen in Figure 1, and the mandril withdraws from
the dies as it is carried around on the eccentric C, leaving the shoe in the
female dies, and the shoe falls out as the arm L" moves back, thus opening
the dies; the arm L again rises as the eccentric C moves around with the
mandril D, and the dies Q, Q, are brought into position to receive the next
forming shoe. It will be noticed that the female die Q, Q, is dovetailing or
inclined under, as seen at W, Figure 6. This gives the shoe a slant or taper
from the hoof, which is desirable, and as the shoe cools it will shrink around
the mandril and tend to draw the shoe out of the dies; but by dovetailing the
female dies as above shewn the shoe cannot be drawn therefrom by the
mandril, and the mandril being also tapering, is thereby readily withdrawn
from the shoe, leaving it in the female die; thus a twofold object is obtained,
that of bevelling the shoe and withdrawing the male die. The movement of
the mandril gives a rolling pressure by the shoulders D¹ upon the shoe from
the toe to the heel, consequently the whole pressure is not upon the entire
shoe at once, which relieves the machine from the strain required in pressing
the whole face of the shoe at once; besides, a rolling pressure such as I have
accomplished makes a more perfect shoe, for any surplus iron the pattern d
may contain is rolled or pressed onward into the heel of the shoe. The
shears T work in guides e, e.
To the shears is attached a connecting rod f,
which is attached to the lever g by a pin point g¹; the end of the lever being
hung to the rod h, Figures 3 and 4, which forms its fulerum. The rod i is
connected to the end of the lever and to the spring j, Figure 3. By the action
of this spring the lever g is raised, and with it the cutter, so that the heated
bar d can be passed into the gauge (see Figures 8 and 9) through the opening
K in the shears under the cutter T. By the action of the cam G upon the
lever g the cutter is so operated that the iron is cut off from the bar the desired
length for the shoe just before the mandril takes it from the gauges. The
gauge S is bolted to the top of the plate m, as is also the gauge S¹, in such a
manner that they can be set to or from each other in proportion to the size of
the shoe. In the gauge S is a moveable slide 1, which is secured in place by
the screw m, Figure 8. The inner end of said slide is turned up at right
angles, as seen in Figures 4 and 9, against which the end of the bar is pushed
so as to determine the length to be cut off for the shoe. This slide can be
readily adjusted to gauge the length of the iron for shoes of any size, and a
mandril of any desired size may be attached to the eccentric C, and the gauges

page_text: adjusted accordingly. As the bar is fed into the gauges flatwise and the
mandril presses upon the edge of the iron, in forcing it from the gauges the
tending is to tip or turn the flat side of the bar to the mandril, which would
spoil the shoe and cause an under strain upon the machine. To prevent this,
and to keep the bar in a flat position, I use the two clamps n, n, Figures 2, 4,
8, and 9, which are so secured to the upright portion of the gauges that they
may be raised or lowered according to the thickness of the bar, consequently,
when the bar is in the clamps it cannot turn flatwise to the mandril.
Having fully described and ascertained the nature of my Invention, and in
what manner the same is to be performed, I claim,―
First, the adjustable gauges S, S', with the moveable slide e, and adjustable
clamps n, n, operating conjointly with the mandril D and jaws U, U, as and
for the purpose herein described.
Second, I claim the jaws U, U, springs V, V, gauges S, S¹, and mandril D
on the eccentric C, when arranged to operate conjointly in the manner and for
the purpose specified.
Third, I claim the eccentric C, mandril D, the primary and secondary
arms L, L", when operating conjointly in the manner and for the purpose set
forth.
Fourth, I claim the cam G, lever g, and spring j, in combination with the
shears or cutter T, operating in the manner and for the purpose set forth.
Fifth, I claim the arrangement of the cams F, F, arms I and I, the bar H,
arm J, and rock shaft K, and arms L, L", substantially as and for the purpose
set forth.
Sixth, I claim, the cam lever N, rods O, O, and spring M, with the roller P
and arms L, L", in the manner and for the purpose specified.
In witness whereof, I, the said George Haseltine, have hereunto set my
hand and seal, this Twenty-eighth day of October, in the year of our
Lord One thousand eight hundred and sixty-two.
