I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham in
the County of Warwick and 322 High Holborn in the County of Middlesex,
Civil 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 consists in the combination in a machine for swaging wire to
form bicycle-spokes and similar articles, of pairs of swaging-dies and a support
common to and movably seated between the anvil-members of said pairs of dies,
and adapted to sustain said anvil-members at different distances apart from each
other, together with actuating mechanism adapted to impart swaging-movement to
the reciprocating members of said pairs of dies: whereby more than one bicycle-
spoke, or like article may be simultaneously produced by the machine.
In the drawings
Figure 1 is a side elevation of the machine;
Figure 2 is a front end elevation;
Figure 3 is an enlarged front end, sectional elevation, on line x, x, Figure, 1;
Figure 4 is an enlarged sertional plan, on line y, y, Figure 2; and
Figures 5 and 6 are respectively a side elevation and plan of the die-supporting
frame.
A is the die-supporting frame, preferably in the form of a segmental block,
recessed downwardly from the top to accommodate the dies and their adjunctive
mechanism, the top being closed by a cap, a, and the frame having lateral way-
plates, a', a², a back-plate, a³, and removable front-plates, a. The frame or
block, A, projects from or over-bangs the rearward edge of a base-plate, aº,
adapted to be detachably mounted on the main frame, as, of the machine.
B is an annular recessed head, having the internal, transversely grooved ring, b;
and, b, are cam-blocks severally seated in said ring-grooves and having stems, b³,
extending through apertures in the ring and head with adjusting-nuts, 63, on their
exterior threaded ends.
For the purposes of this invention the head, B, is preferably revoluble and the
die-frame is stationary, as shown; and, to this end, the head may be mounted on
and rotated by a driving-shaft, 64, while the frame, A, is seated on the machine so
that it projects into the recessed head, B, to bring the dies and their actuating
mechanism in line with the range of cam-blocks, 6', so that the rotation of the
head will cause said cam-blocks to act upon said mechanism to impart the swaging
movement to the dies.
The essential feature of this invention consists in pairs of swaging-dies, C, C¹,
seated between the way-plates, a', a³, in the frame, A, and a support, D, movably
seated between the anvil-members, c, of said pairs of dies, and adapted to sustain

page_text: said anvil-members at different distances apart from each other, in combination
with mechanism, which may be that hereinafter described, in operative engagement
with the reciprocating-members, c¹, of said pairs of dies, and the circular range of
actuating cam-blocks, b¹.
In the machine illustrated in the drawings two pairs of dies, C and C, are
shown; and this will be found the desirable number of pairs of dies to employ in
carrying out the invention. And the support, D, is preferably in the form of a
wedge which has sliding movement between the anvil-members, c, of the pairs of
dies in the direction parallel to and desirably coincident with the axis of the head, B,
as shown. The vertical sides of the wedge are inclines, while its upper and under
faces may be parallel planes. At c, c³, are shown anvil-blocks which are desirably
employed in machines of this class, and, in the machine shown, are respectively
interposed between the anvil-members, c, of the pairs of dies, C. C, and the
inclined sides of the wedge, D; and the faces of said anvil-blocks adjacent to said
sides of said wedge are correspondingly inclined to fit thereto. These anvil-blocks
are harnessed to the wedge so that the movement of the wedge in one direction
will draw the blocks apart from each other, and the movement of the wedge in
the opposite direction will bring the blocks towards each other; and this may be
conveniently accomplished by means of plates, e, attached to the upper and under
faces of the anvil-blocks and reaching over the upper and under faces of the
wedge, D, and carrying lips, e, which engage the grooves, d, in said faces of the
wedge, which grooves are respectively parallel to the inclined sides of said wedge,
as shown.
The movement of the wedge, D, may be effected and controlled and its position,
with its attached anvil-blocks, definitely fixed, relatively to the anvil-members, c,
of the pairs of dies, C, C', by a lever, d', one arm of which engages the wedge, as
by a sector, d², meshing a rack, d³, on the under face of the outward end of the
wedge, while the other arm engages a rock-shaft, d, as by a sector, d, meshing a
pinion, de, on said shaft, said rock-shaft having a hand-lever, d', adapted to
engage adjustable stops, de, on the machine frame to limit the movement of said
lever.
The definite oscillation of said rock-shaft and consequent definite vibration of
the lever, d', will definitely reciprocate the wedge, D, which will thus move the
anvil-blocks, and c³ to certain definite positions and cause the anvil-members, c,
of the pairs of dies, C, C', to more or less approach or recede from their
reciprocating-members, c', so that the degree of action of the dies upon the wire
they are acting upon may, while the machine is in operation, be accurately
controlled, or the entire relief of the wire from the action of the dies be effected.
The mechanism preferably employed in connection with the circular range of
cam-blocks,, to actuate the reciprocating-members, c' of the dies, comprises
levers, e and el, working in lateral recesses in the frame, A, and respectively
pivoted at their upper and lower ends, and having at their free ends friction-
rolls, e, and provided with springs, e, which act to throw their free ends outwardly
into the path of the cam-blocks, b', in the head B; together with follower-blocks, e*
and e, which are respectively linked to the said levers and are seated to play
between the way-plates, a', a, and to impinge upon the outward faces of the
reciprocating-members, c', of the respective pairs of dies, C and C.
The front-plates, a', of the frame, A, preferably have outwardly flared feed-
apertures, a, registering with the entrances to the matrices in the respective pairs
of dies, C and C, to guide the wire to be swaged into said matrices; and the
hack-plate, a³, and rear wall of the frame, A, have apertures, alo, registering with
the exits from said matrices and leading into the hollow-shaft, 6, so that the wire
passing from the dies may extend into said shaft.
The special die-frame herein shown and described, together with the head, B,
and its range of cam-blocks, and the mechanism for operatively connecting the
cams to the described follower-blocks, may be employed in connection with and to
impart swaging movement to a single pair of dies.

page_text: It will be understood that mechanism which is well known and employed for the-
purpose, may be used to hold and feed the wire to be swaged to the swaging-dies,.
although the same is not herein shown, it forming no part of this invention.
