RESUDVE
I RICHARD RUSSELL GUBBINS of 17 Park Road New Cross in the county of Kent
Engineer do hereby declare the nature of this invention to be as follows:-
This Invention relates to certain improvements in machines for making horse shoes
from bars of iron which have been previously rolled for the purpose, with calkins, toe
pieces, and creases, and also for swaging and forming the said horse shoes in any
desired manner in a more expeditious and economical way than now adopted.
My invention consists of a substantial iron framing of rectangular plan about the
height of an ordinary domestic table, and about five or six times the length of its
width. Lengthwise upon this, and mounted in sliding bearings is a stout steel bar
which is caused to travel backwards and forwards, horizontally by means of a crank
or other reciprocating device. It is however essential that the reciprocating motion
of the said bar must be so devised as to leave both its ends free to receive the bending
devices with which they will be furnished. Each such end of the said bar being thus
provided, and the corresponding opposite ends of the machine being also furnished
with the necessary stops or dogs and swaging blocks, the bar becomes double acting in
the accomplishment of its work and a supply of horse shoe blanks being fed in at
each end, one of them is bent at each motion of the sliding bar, and this arrangement
enables me to turn out double the quantity of work hitherto done by this class of
machine.
In supplying blanks to the bending devices it is usual to crop them from the bars,
cold and having heated them in an ordinary furnace to feed them in one by one with
a pair of tongs as required. This system however entails so much labour that I prefer
taking the bars as they leave the rolls and reheat them in a long furnace one end of
which is placed close to the bending device and from this they are fed to the machine
by automatic grippers. A shearing blade cuts off each blank from the bar before the
bending device commences to act.
It will be seen that according to this invention two differing types of shoe may be
made simultaneously upon one machine, and it will be of much advantage to be thus
able to make the front and hind shoes at the one operation.

page_text: I prefer that kind of bending device in which the blank is bent by rollers, carried
by crossed levers around a fixed forming block, as the latter may be fixed upon the
platen of a press and the shoe may thereby be pressed and stamped for clipping &c.
without any further handling. The other ends of the crossed levers may be guided
by cams so that the rollers will press the blank against the forming block in such a 5
way as to produce shoes with wedge heels or with one or both sides flattened as may
be required. The calkins on machine made shoes by the existing process of rolling
are not satisfactory and another portion of my invention consists in providing punches
or cutters, actuated by eccentrics or any convenient moving portions of the mechanism
for the purpose of trimming such calkins or projections to the requisite shape before 1
the bending devices come into action.

Improvements in Machines for Swaging, Bending, and Forming
Horse Shoes.
I RICHARD RUSSELL GUBBINS of 17 Park Road New Cross in the county of Kent
Engineer 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 :-
This invention relates to certain improvements in machines for making horse shoes
from bars of iron which have been previously rolled for the purpose, with calkins, toe
pieces and creases, and also for swaging and forming the said horse shoes in any
desired manner in an expeditious and economical way and consists of improvements
upon the subject matter of Letters Patent No. 4210 dated 23rd December 1873
granted to William Robert Lake and this present invention will be more readily
understood by perusal of the specification of said Letters Patent.
My invention consists of a substantial iron framing of rectangular plan of a suitable
height. Lengthwise upon this and mounted in sliding bearings is a stout steel bar
which is caused to travel backwards and forwards horizontally by means of side levers,
crank, quadrant or other reciprocating device. It is however essential that the
reciprocating device which actuates the said bar must be so arranged underneath as to
leave both its ends free to receive bending devices with which they will be furnished.
Each such end of the said bar being thus provided and the machine being also
furnished with the necessary stops or dogs and swaging or squeezing blocks as fully
described in Patent No. 4210 A.D. 1873, the bar becomes double acting in the
accomplishment of its work that is to say each end of it acts in fulfilment of its
function and a supply of horse shoe blanks being fed to it at each end one of them is
bent at each motion of the sliding bar and this arrangement enables me to produce
double the quantity of horse shoes hitherto done upon this class of machine as described
in the before mentioned Patent No. 4210 A.D. 1873.
Machines constructed according to my invention are illustrated in the accompanying
sheets of drawings whereof Fig. 1. is a top plan view and Fig. 2 is a sectional
elevation at line ab Fig. 1. Figs. 3 and 4 sheet 2 show respectively elevation
and plan of machine. Similar reference letters describe similar parts in both
drawings.
A is the framing of the machine, B is the sliding bar, working between the
guides B' upon the framing A. C, C, are the bending or forming blocks.
The bars D D work in suitable guides and carry on each of their ends the swaging.
blocks d d d d-d', d', d¹, d' are stops.
Upon the underside of bar B sheet 1 is the rack B' in gear with which is the
toothed quadrant E for the purpose of giving the reciprocating motion to bar B. The
bars D, D, have a reciprocating motion imparted to them by means of the eccentric
rod F to which they are attached. The whole of the parts are driven by means of the
pulley G.
Thus when a horse shoe blank is fed in at either end of the machine as shown in
Hotted lines at z Fig. 1 the swaging blocks or squeezers d first come into operation and

page_text: flatten the ends as required against the stops d'. The bar B then comes forward and
bends the shoe blank. It will be seen that the bar B also carries the two cross bars H
(Fig. 1) upon which are the inclines H¹ which serve to operate the levers I pivoted
on the upper surface of the bed of the frame at 1. The levers carry rollers K
which by the motion of the bar B are pressed against the ends of the shoe blank to
assist the bending thereof as described in the Patent No. 4210 A.D. 1873 before
referred to.
:
At each end of my improved machine is a press M'M' provided with the requisite
dies for pressing and finishing the shoes. The shoes are left by take off mechanism
carried by the bending devices immediately over said dies in position to be pressed as
shown at in the plan Fig. 1. These presses are worked by crank pins o in the
gears by bevil wheels P from off the driving pulley G as will be understood by
reference to the drawings.
In sheet 2 I show another construction of my improved machine wherein the bending
bar B is carried by two cross bars S S and slippers S1, S1, in guides S³, S³,
(Fig. 4) formed in the sides of framing A and actuated by side levers E taking
motion from the same crank pins o o which work the presses M M².
The squeezers D, D, are in this arrangement also driven by levers worked by crank
pins as will be hereinafter more fully described.
For the sake of clearness I have omitted to show the levers I of Fig. 1 in these i
drawings but it will be readily understood that they will be worked by cam plates
carried by the bar B in the same manner as in the previously described case.
The spur wheel G Fig. 3. by means of the pinion g gives motion to the three large
spur wheels P P¹ and P².
P and P² are furnished on the ends of their shafts with heavy discs O, O¹, in which
are firmly secured crank pins oo¹ which work the presses M, M', at each end of the
machine by the connecting rods QQ'.
The crank pins o are made long enough to carry the connecting rods R which work
the bending bar B through the side levers E and links E'.
The spur wheel P¹ besides transmitting motion to the press M' also operates the a
squeezers D D by means of the crank pins o² of and side levers B¹ B¹ shown in Fig. 3
dotted lines.
The general construction of this machine being the same as that already particu-
larized need be no further described.
It will be seen that according to this invention two differing sorts of shoe may be
made simultaneously upon one machine and it will be often found convenient to make
front and hind shoes in this manner.
。 Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
Firstly. In a machine for swaging, bending, and forming horse shoes the com-
bination of the various parts constructed and operating substantially as and for the
purpose herein described and shown in the annexed drawings.
Secondly. In a horse shoe bending machine the combination of the bending bar
with the quadrant or levers E, E, substantially as described.
Thirdly. In a horse shoe bending machine the combination of the bending bar B
with the quadrant or levers E or their equivalent and the presses M M' substantially
as set forth.
