page_text: I, THOMAS DICKSON RICHARDSON, of the United Horse Shoe and Nail Company,
of Cubitt Town, in the County of Middlesex, Engineer and Manager of works do
hereby declare the nature of my invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to machinery of the kind or class described in the Specifi-
cation of Letters Patent dated 23rd December A.D. 1873, N° 4210, and comprises
various improvements hereinafter set forth.
In the accompanying drawings

Figure 4 is a section on the line ¹, x', Figure 2.
Figures 5, 7 and 9 are plans, and
Figures 6, 8 and 10 are side elevations, shewing various forms of swages which.
I use in my improved machine.
Figure 11 is a side elevation.
Figure 12 an end elevation, and
Figure 13 a plan, partly in horizontal section, of a hammering machine con-
structed according to my present invention.
Referring to Figures 1 to 10 inclusive, A is the frame of the swaging and bending
machine. B is the driving shaft which is carried in suitable bearings in the said
frame and is provided with fast and loose pulleys B¹, B. C is a pinion fixed on
the shaft B and geared with a toothed wheel D¹ fixed on a shaft D carried in
bearings in the frame A and bracket A'. A bevel pinion D' is fixed upon the
shaft D and geared with a bevel wheel E¹ fixed on the vertical shaft E. This
shaft is passed through a bearing in the frame A, and its lower end is supported in
a step A³ at the upper end of the bracket A¹. A disc-crank F is fixed upon the
upper end of the shaft E, and its crank-pin F is coupled, by means of a connecting
rod G, with a har H fitted to slide to and fro between guides I upon a platform I

reciprocating motion is imparted to the bar H. The shoe-former or pattern block
is to be secured to a bar H³, which is firmly connected with the bar H by screw-
bolts H passed through slots H³ in the bar H and through holes in the bar H, so
that the bar H¹ can be adjusted to regulate the position of the said pattern block
relatively to the other parts of the machine, and thus adapt the machine for the
manufacture of shoes of different shape or size.
J,J.are the swages which are secured to the ends of two bars J fitted to slide to
and fro between guides J' upon the platform I. These swages are arranged to
operate in combination with fixed blocks K, as, and for the purpose, described in
the said former specification, but are actuated by the mechanism hereinafter
described, that is to say:-]
-Each bar J¹ is coupled to an arm L' fixed upon a rock-
shaft L carried in bearings in the frame A. The holes in the ends of these arms,
through which the coupling pins are passed, are slotted to permit a slight up and
down movement of the said coupling pins therein. An arm L is also fixed upon
the rock-shaft L, and is connected, by means of the rod M and strap M³, with an
excentric M fixed upon the shaft E. The said swages will, therefore, be operated
simultaneously, instead of one after the other as described in the said former
Specification.
An important feature of my present invention is the employment of inter-
changeable swages, so that I can adapt the machine for making shoes of various
shapes. In the machine described in the said former specification, the swages are
formed integrally with the sliding bars; but, according to my present invention,
I secure the swages to the bars by screw-bolts or otherwise, so that they can be
readily removed and replaced, or swages of different shape can be substituted
therofor.
•
N, N are the lovers for bending the blanks, which levers carry rollers N¹ fitted
to rotate upon studs N' and projecting through curved slots I* in the platform I, as
described in the said former specification. I provide improved means for adjusting
these levers, that is to say, each lever is pivotted upon a screw-bolt O fitted to slide
in a slot in the platform I, and an adjusting screw O³ is inserted in the said
platform and bears against the said bolt O. By turning the screws 0¹ in one or the
other direction, the levers N can be moved towards or away from each other,
without altering the position of the rollers N¹ in the slots I sufficiently to affect,
their movement therein.
P is a transverse bar which is firmly attached to the sliding bar H, and which
operates the levers N as described in the said foriner specification. The bar P is,
according to my present invention, arranged beneath the platform I and is con-
nected with the bar H by means of a block P¹, which is fitted to slide in a slot in
the said platform. By arranging the said transverse bar in this manner, I obviate
the necessity for employing long studs in the said levers as in the machine
described in the said former Specification.
The swaging and bending operations are effected substantially as in the machine
described in the said former specification.
Referring to Figures 11, 12 and 13, which show the hammering machine, a is
the frame of the said machine; b, b are the rotary hammers which are carried by
discs b¹ mounted upon a shaft c supported in standards d on the said frame. The
construction and operation of these hammers are substantially the same as those of
the rotary hammers described in the said former specification.
e is the bed supporting the anvil-die. This bed is arranged to be reciprocated
between guides f. f¹, beneath the hammering rollers b as heretofore. But,
according to my present invention, I provide for adjusting the guide f to com-
pensate for wear. For this purpose, I provide set-screws g which are screwed into
the upper part of the frame a, and bear against the guide-strip so that the latter
can be adjusted towards the dovetailed rib h of the bed. In some instances
I provide other suitable means for adjusting the said guide-strip f. If desired, the
strip f¹ may also be made adjustable.

page_text: The bede has positive reciprocating motion imparted to it by means of cams i, i
as heretofore, but the lever j, instead of being forked at its free end and engaging
with a projection upon the underside of the bed, is connected to the underside of
the said bed by means of a link j. k is a counter-weight for assisting the back-
ward movement of the bed by the cam 1.
I provide for holding the blanks upon the anvil-die during the hammering
operation as follows, that is to say:- is the central portion of the said die, which
is adapted to fit the inside of the shoes to be hammered; m, m are two projections,
which are so situated as to be in proximity to the outside of the heel portions of a
shoe when in the die, and which have a space n left between them for a purpose
hereinafter described.
o, o are two clamps or levers which are pivotted to the bed e so that their
forward ends o¹ project into the space n. Two cam-blocks p are attached to the
frame a and have oppositely inclined surfaces p¹ p² at their ends and parallel
portions p between the said inclined surfaces as shown in dotted lines in
Figure 13.
The levers o are so arranged relatively to the blocks p that, in the to-and-fro
movement of the bed e and levers o, the rear ends o³ of the said levers will impinge
against the cam-blocks p, and the levers will thereby be caused to engage with the
shoe on the anvil-die as hereinafter set forth.
A spring q is attached to the bed e and bears against the inner sides of the
levers o.
This spring tends to hold the said levers in the position shown in
Figure 13; when the said levers, in, the to-and-fro movement of the said bed, are
operated by the blocks 2, the said spring is compressed, and, when the levers o move
away from the said blocks, the said spring, by its reaction, operates the said levers
to release the shoe on the anvil-die.
The operation of this clamping mechanism is as follows, that is to say:-After a
bent blank has been placed upon the anvil-die, the machine is started and the bed s
is moved to bring the said blank beneath the rotary hammers or hammering
rollers. During this movement, the ends o² of the clamps or levers o impinge
against the inclined surfaces p¹ of the blocks p and the levers are thereby operated
so that their ends o' are moved apart and come into contact with the heel portions
of the shoe-blank, which are then tightly gripped between the ends o¹ of the said
levers and the projections m. While the hammering is being performed, the
ends o² of the levers o are in contact with the parallel surfaces ps of the blocks p
so that the said levers continue to hold the blank. As soon, however, as the
blank has passed from beneath the hammering rollers, the ends o³ of the levers are
pressed against the inclined surfaces p³ and moved apart by the spring q, the blank
is thus released and can be removed in any convenient manner.
To adapt the machine for use in the manufacture of shoes of different size or
shape, or both, I sometimes provide means for adjusting the cam-blocks p. In
the machine shown in the drawings, I use, for this purpose, screws ? which are
inserted in tapped holes through the flanges a formned on the frame a in proximity
to the blocks p. Set-screws t. are passed through slots p in the blocks pand
screwed into the frame a to hold the said blocks in any desired position. By
slackening the set-screws t and turning the screws 7 in one or the other direction,
the blocks p may be adjusted as required.
Although I have hereinbefore described my improved machinery as constructed
for use in the manufacture of horse-shoes, it is obvious that it may be adapted for
swaging, bending or hammering metal bars for other purposes.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
First The combination of parts comprising the crank fixed upon the vertical
shaft and connected by bevel gearing with the driving shaft, substantially as, and
for the purpose, set forth.

page_text: Second-The provision of means, substantially as set forth, for adjusting the
position of the shoe-former or pattern block relatively to the other parts of the
machine, as, and for the purpose, described.
Third The employment of interchangeable swages adapted to be secured to
the sliding bars, substantially as, and for the purpose, set forth.
Fourth The combination of parts comprising the rock-shaft, the arms fixed
thereon, the eccentric formed or fixed upon the vertical shaft and connected with
one of the said arms, and the sliding bars carrying the swages, substantially as, and
for the purpose, set forth.

their adjustment, substantially as, and for the purpose, described.
Sixth The combination, with the sliding bar H, of the transverse bar secured
thereto and arranged beneath the platform, substantially as, and for the purpose,

Ninth The employment, in the hammering machine, of levers pivotted to the
reciprocating bed and so arranged that their short arms extend into the space
between the heels of a shoe when on the anvil-die, and means for operating the
said levers for the purposes above specified.

Tenth The combination of parts comprising the projections m, the pivotted
clamps or levers o and the cam-blocks p (with or without means for adjusting the
said blocks), all substantially as, and for the purposes, set forth.
