Improvements in Machinery for Swaging Rods and other Round
Articles.
I, WILLIAM HENRY DAYTON, of No. 13 Litchfield Street, Torrington, in the
State of Connecticut, United States of America, Machinist, do hereby declare the
nature of this invention to be as follows
This machine is intended especially for swaging the rods or wires made use of
in the construction of bicycles and other wheels, but the mechanism may be
employed in the swaging of other round articles.
In the swaging of spokes for wheels it is advantageous to leave the ends of the
spoke of the full size of the wire, or nearly so, in order that the screw thread may
be cut upon the same without the wire thereby becoming weaker at the ends than
it is in the other portion, and in the swaging of tapering articles and rods, and
wires that require to be thicker at one place than another, it is desirable to open
the swaging dies for the larger portions and to bring them more closely together
for the smaller portions of such round article.
In the Specification of my application for English Patent No. 8803, dated
May 10, 1892, a machine is described in which wedges are made use of for acting
upon the dies to open and close the same more or less and thereby reduce the rod
or wire to a greater or less extent, and the first part of the present invention
relates to modifications of and improvements in the devices for opening and closing
the revolving dies, and the second part of the said invention relates to the
mechanism made use of for feeding the rod or wire to the dies during the swaging
operation.
I make use of a pair of swaging dies, the adjacent surfaces of which are grooved
with semi-circular or nearly semi-circular grooves tapering more or less towards
the ends, so as to adapt such dies to the swaging operations to be performed, and
these dies are in a cross mortice at the end of a revolving shaft, and the dies are
within a stationary shell, and there are rollers between the dies or die blocks and
the inner surfaces of the stationary shell, so that as the shaft and dies are revolved,
the outer ends of the dies or die blocks coming into contact with the surfaces
of the rollers, are by such rollers pressed towards each other to perform the
Swaging operation, and there is an end movement given either to the shaft or to
the range of rolls in regulating the opening or closing of the dies, and there is an
inclined surface acting in connection with these rolls to effect such opening or
closing of the dies.
In one form, in which this improvement is made, the rolls themselves are conical
and a movement is given to the rolls end wise, so as to force the dies nearer together
or to allow them to open further, and this end movement is either given to the
group of rollers bodily, or to the shaft and dies in relation to the rolls, and in
cases where the rolls are cylindrical and the interior surface of the shell is slightly
inclined, the same object is effected by end wise movement given to the shaft to
change the position of the dies in relation to the surfaces of the rolls.
In the feeding operation I make use of a pair of pincers that are opened or
closed by the action of a wedge and toggle, and these pincers are set upon a sliding
bed supported in slide ways and a frame, and there is a lever to give motion end-
wise to the slide and the pincers, and a cam and connecting rod to act upon the
lever, and there is also a second cam revolving in unison with the other cam to
give motion to the shaft and dies end wise, or to the group of rollers to regulate
the extent of opening and closing of the dies according to the position of the"
article between the dies, thereby regulating the shape that is given to the article"

page_text: in the awaging operation, and the blanks, wires, or rods to be acted upon arc
preferably supplied automatically, that is to say, they are placed in a hopper or
slide and taken out one by one and transferred to the pincers. This is effected by
the action of a sector and rock shaft, or where the wires or rods are long, two of
these 'sectors are placed upon the same rock shaft, and motion is given to the rock
shaft and sectors by gearing in such a manner that the wire or blank is brought
down into position as one completed article is allowed to drop by the opening of
the pincers, and the pincers come up and seize the next wire or blank and carry
the same in between the swaging dies.
I find it advantageous to make use of a stop to limit the backward movement
of the pincers, such backward movement being effected by the action of a spring,
so that in finishing such an article as a spoke, the tapering portions between the
smaller diameter and the larger diameters may be both finished off with great
accuracy, the finishing of the first reduction being effected upon the return move-
ment so as to be accurate in its length from the last reduction that has been
effected as the blank has been fed in between the reducing dies.
This stop is automatically withdrawn at the proper time to allow the pincers to
complete their backward movement and to open and drop the finished spoke or rod;
and to receive another as before mentioned..
When this invention is made use of for swaging small articles such as needle
blanks, nail blanks, etc., the blanks may be put into a hopper and discharged from
the same automatically into the vertical slide or holder from the bottom of which
the blanks are taken by the quadrant feed before mentioned. It is also to be
borne in mind that the speed with which the pincers are moved to feed in the
article that is being operated upon, must be regulated in proportion to the extent
of the reduction, so that the revolving swaging dies may revolve at a uniform or
nearly uniform speed, and the speed of movement of the pincers will be regulated
by a cone of pulleys or gearing, so that when the reduction is heavy the speed of
movement will be less, and the reverse.
The toggle mechanism for opening and closing the pincers and the stop may
receive their motion from a second cross shaft geared to the main driving shaft by
the longitudinal shaft and screw pinions.

Improvements in Machinery for Swaging Rods and other Round
Articles.
I; WILLIAM HENRY DAYTON, of No. 13 Litchfield Street, Torrington, in
the State of Connecticut, United States of America, Machinist, do hereby
declare: the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:--
This machine is intended especially for swaging the rods or wires made use of
in the construction of bicycles and other wheels, but the mechanism may be
employed in the swaging of other round articles.
In the swaging of spokes for wheels it is advantageous to leave the ends of the
spoke of the full size of the wire, or nearly so, in order that the screw thread may
be cut upon the same without the wire thereby becoming weaker at the ends than
it is in the other portion, and in the swaging of tapering articles and rods, and
wires that require to be thicker at one place than at another, it is desirable to open

page_text: the swaging dies for the larger portions and to bring them more closely together
for the smaller portions of such round article.
In my English Patent No. 8803, dated May 10, 1892, a machine is described in
which wedges are made use of for acting upon the dies to open and close the same
more or less and thereby reduce the rod or wire to a greater or less extent, and the
first part of the present invention relates to modifications of and improvements in
the devices for opening and closing the revolving dies, and the second part of the
said invention relates to the mechanism made use of for feeding the rod or wire to
the dies during the swaging operation.

Fig. 11 is a section of a modification, and Fig. 12 is a section and Fig. 13 a face
view of the dics with conical rollers, and
Fig. 14 is a detached view of means for moving the conical rollers.
The devices for opening and closing the dies to which the first part of my inven-
tion relates are shown in Fig. 7 and in larger size in Figs. 10 to 14.
In Fig. 10 A represents a shaft revolved by competent power and carrying in a
transverse mortise the dies BB which are held in position by a suitable cap
plate C, and D is the head which surrounds the revolving shaft and supports the
same, and I have represented wedge acting surfaces 3 at the ends of the swaging
dies B, so that when the shaft A is moved in one direction in relation to the
head D the dies are brought closer together by the inclined or wedge-acting
surfaces 3, and when the parts are moved in the opposite direction the dies B
are allowed to open further, and it is to be understood that either the head D
can be moved in relation to the shaft A, or the shaft A be moved in relation to the
head D.
I have represented a collar 4 passing into a groove in the shaft A, and a
lever H by which the collar can be moved so as to give motion end wise to the
shaft A.
In Fig. 10 of the drawing I have represented a group of rollers K around
within the shell D1 or flange of the head D, such group of rollers being held in
position in any suitable manner, such as by the rings L L', and in this case the
rolls K are advantageously cylindrical, but they might be slightly tapering, but
such rolls stand in such a position that the surfaces 3 which act upon the outer
ends of the swaging dies B are at an inclination to each other.
In Fig. 11 the toggle blocks K' and their springs are represented with their
inner surfaces inclined to each other, as shown at 3, and in consequence of the
inclination of the surfaces that act upon the outer ends of the swaging dies,
such swaging dies can be made to reduce the article acted upon to a greater
or less extent, so that one portion of such article may be of greater diameter than
another.
In Figs. 12 and 13 the shaft A is suitably supported by a head D having a pro-
jecting rim or shell D', and the range of rolls E is within the shell D' and around,
the shaft A and its dies B.
The rolls E instead of being cylindrical are more or less tapering, so as to act

page_text: like wedges when an end movement is given to such rolls in relation to the
swaging dies B, that is to say, the rolls E may be moved endwise in the direction
of the axes, or the shaft A may be moved end wise to bring the swaging dies B into
different positions in relation to the rolls E; in either instance the wedge action of
the rolls is the same.
It is generally preferable to place the rolls E with their axes parallel to the axis
of the shaft A and to mount these rolls E in circular rings FF that are con-
nected together, so that the group of rolls and the rings that support the same
can receive motion endwise of the rolls and parallel to the axis of the shaft A.
In this case the interior surface of the shell D' is slightly conical, and the
outer ends of the swaging dies B are slightly beveled at the same angle as the
tapering rolls, and the bearings or holes in the rings FF1 for the axes of
the rolls E should be elongated in the direction of the radii to allow for the
rolls being moved endwise within the shell D₁ towards the smaller diameter of
such shell, or outwardly towards the larger diameter, and when moved inwardly
the dies B will be brought closer together in the swaging operation, and when the
rolls are moved outwardly the dies B will be further apart in the swaging opera-
tion, thereby allowing for varying the size of the different parts of the round
article that is being swaged.
In order to give motion bodily to the group of rolls, any suitable mechanism
may be employed; I have represented the face ring G to which is connected a
screw ring H screwing upon the exterior of the shell D. By rotating this
screw H and face ring G the group of rolls will be pressed inwardly, and upon
releasing or unscrewing the ring H the rolls will move outwardly, either auto-
matically or by the action of a spring follower, illustrated at I, Fig. 12.
I find it the most advantageous to retain the rolls in their proper relative
positions by supporting the axles of the rollers in the rings F F', but the axles of
such rolls may be in the form of bolts passing through the rolls and projecting
from one ring, to which ring a motion can be given in either direction by suitable
mechanism, such for instance as a clip D acted upon by a screw, shown in Fig. 14.
In all instances the opening and closing of the dies will be regulated by the relative
position of the conical or tapering rolls to the swaging dies.
The machine adapted to contain the dies before described is represented in
Figs. 1 to 9, in which the swaging dies A are in a slot across the end of the
revolving shaft B, and there is a circular group of rollers D around the shaft and
dies and within the shell C, and this shell C is part of or connected with a standard
or frame C that is adapted to supporting the parts of the machine, and there is a
framework extending out from the shell C or standard Cand in which are
guide ways for the sliding bed J which is adapted to receive the pincers H that are
in line with the axis of the swaging dies and receive the blank that is to be operated
upon.
The counter-shaft T runs longitudinally of the machine and it is supported at
its ends in bearings or boxes 7 and 8 and it is provided with a driving pulley U
at one end, the belt of which preferably leads to a cone of pulleys, so that the
speed of this counter-shaft T can be varied according to the work that has to be
performed, it being understood that this counter-shaft T is revolved more slowly in
proportion to the revolving shaft B when the reduction made by the swaging dies
is heavy, and when the reduction is light the counter-shaft T can be revolved faster
in proportion to the revolution of the shaft B; and I remark that it is advan-
tageous to provide a fly wheel B', on the shaft B and a fast pulley B and loose
pulley B³, so as to adapt the apparatus to a belt for driving the shaft B, and it is
advantageous to support the shaft B in a tubular extension C' from the standard C¹
or shell C.
1.
Upon the counter-shaft T there are worm pinions 9 and 10, the pinion 9 rotating
a wheel V upon a cross shaft F and the pinion 10 rotating a wheel W upon a
cross shaft F, and upon these shafts there are cams for moving the parts of the
apparatus as hereafter described.

page_text: Upon the shaft F is a cam E properly shaped to give end wise motion at the
proper time in bringing the dies nearer together or further apart.
I have repre-
sented the cam E as acting upon a lever arm 11 upon a rock shaft 12 with an
arm 13 forked at the upper end and acting upon a collar 15 between the nuts 14
upon the tubular revolving shaft B, and in consequence of placing the rollers D at
an inclination, as represented in Fig. 7, these rollers act to close the dies nearer
together when the shaft B is moved backwardly and to allow them to open further
as the shaft B is moved forward, and it will be observed that the spring 16 acts to
keep the lever arm 11 towards the cam E and to move the shaft B backwardly,
and the cam E gives the movement in the other direction and also regulates the
action of the spring upon the respective parts.
In cases where wedges are made use of for regulating the opening between the
dies, as seen in my aforesaid Patent, the cam E will be employed for giving motion
to the wedges endwise, the lever connections being arranged accordingly.
The sliding bed J which carries the pincers H receives its motion from the lever L
which is pivoted to the frame of the machine at the lower end and connected by a
link 17 at the upper end to the sliding bed J, and there is a connecting rod M to a
lever L' having a roller in contact with the cam N upon the shaft F, which cam N
is so placed and shaped that the bed J, the pincers and the blank, rod or wire to
be acted upon are moved up towards the dies and the rod is passed end wise through
the dies with the required speed as such dies are opened and closed by the action
of the rolls D against the outer ends of the dies or die blocks as the shaft B is
revolved, and according to the shape that is to be given to the article that is being
swaged, so the cams E and N will be varied.
They are represented in the drawing as adapted to the swaging of spokes c
shown in Fig. 6, and the blank is to be held by the pincers H and is passed in
between the swaging dies A and projects behind them the proper distance and then
the dies are gradually closed by the end movement before described, so that such
dies are made to reduce the article to the required size, and the feeding is con-
tinued so as to make the middle portion of each spoke of uniform size or nearly so,
and then the pincers and bed are drawn back to a stop hereinafter described which
arrests the backward movement of the bed and pincers for finishing the surface of
the conical or tapering portion of the spoke between the smaller and larger diameter
near the first end thereof, after which the cam E causes the dies A to be open and
allow the spoke to be withdrawn.
If the spoke is to have au enlargement in the middle, or if a rod or wire is being
Swaged to produce a gradual taper, the shape of the cams E and N will be varied
so as to adapt them to the article that is to be swaged.
Any suitable mechanism will be made use of for opening and closing the
pincers H at the proper time, and also for supplying the wires or blanks to such
pincers, but I prefer and make use of the devices herein described.
The pincers H are pivoted at 18 within a sliding stock H' which may slide
endwise beneath the cross bars or bearings 19, and at the rear end of the stock H¹
there is a screw 20 bearing against a spring 21 supported by the flanges or
bearings 22 upon the bed J, so that this spring 21 allows a slight end wise yielding
movement to the pincers, so that they may act more efficiently in forcing the wire
or blank along between the swaging dies A during the swaging operation, and there
is a spring 23 that acts to open the jaws of the pincers, and a wedge 24 between
the back ends of the pincers to close such pincers, and to the back end of the
wedge 24 a toggle link 25 is connected, and there is a second toggle link 26
pivoted at its rear end to the adjusting screw 27, hence when the toggle links are
brought down into line with each other, as shown in Fig. 4, the pincers are closed
to hold the blank, and when the toggle links are raised up into the position shown
in Fig. 7, the pincers are open for relieving the finished blank and for receiving
another blank.
In order to actuate the toggle links 25 and 26, I employ a link 28 to a crank
arm 29 upon a shaft 30 having an arm 31 with a pin that slides in the slotted bar e

page_text: which has a vertical slide within the guide ways, and at the lower end is a roller
acted upon by the cam y, shown by dotted lines in Fig. 6, which can be shaped so
that it lifts the slotted bar e for closing the pincers and allows the spring to draw
down the slotted bar e for opening the pincers, and this slotted bar é allows the pin
upon the arm 31 to travel along in said slot during the time that the swaging opera-
tion is being performed, and the blank is held firmly by the pincers.
e
I have represented the stop in the form of a lever acted upon in one
direction by spring k, and in the other direction by a cam, so that this
stop comes up in front of the adjusting screw m as the sliding bed J moves
back, and this stop i arrests the further backward movement of the bed, regard-
less of the shape of the cam N, because the spring R is employed to move the
parts and draw the slide bed J back, and the shape of the cam is such that
it allows the spring top to arrest the backward movement of the parts with the
tapering portion o of the spoke c between the swaging dies A so that such part is
fully finished, and then the dies A are opened and the cam draws down the spring
stop and the spring R acts upon the parts to complete the backward movement
suddenly, at which moment the cam g, acting through the intermediate parts, opens
the pincers and the finished spoke is allowed to drop, and then another spoke is
laid in between the jaws of the pincers, and such pincers are then closed and the
operations before described are repeated.
The spokes might be placed in the pincers H by hand, but I prefer to supply
them automatically by any suitable device; I have however shown a rock shaft P
upon which are sectors 001 that are sufficiently long for their curved surfaces to
remain beneath the magazine n which is formed as a vértical trough or holder
for the reception of the blank spokes or wires one above the other. Where the
blank or wire is short, only one of these sectors need be employed, but I have
represented two of such sectors so as to adapt the machine to blanks or wires for
making spokes. This magazine n is suitaby supported from the head or shell C,
and the sectors 001 are beneath the lowest wire or blank in the magazine, and
upon reference to Figs. 3 and 9, it will be seen that the sectors 00₁ are cut away
at such places that when the sectors are turned up into the position represented
in these two figures, the bottom spoke in the range of spokes within the magazine
will drop into the notch, and when the sectors are moved, the blank or wire will be
carried out from the magazine, but all the other wires in the magazine will be
supported by the curved surfaces of the sectors.
Upon the rock shaft P there is a bevel gear, and upon the lever arm s
there are gear teeth engaging the bevel gear, and this lever arms is connected
with the lever arm s¹ with a roller t in contact with the cam u upon the second
cross shaft F, and there is a spring to press the roller t towards the cam u,
and this cam u is shaped in such a manner that in acting upon the rollers s si
the rock shaft P is rotated at the proper time to bring down a blank to the
pincers Hand to return after the pincers have grasped the blank ready for
taking down a second wire or blank at the proper time, and there is a finger 7
pivoted at 32 to one arm of the sector O, and this finger is drawn towards the
blank by a spring 33, but the end of the finger comes against one side of the
magazine so that the movement of the finger is arrested to allow the necessary
space for the lowest wire or blank in the magazine to drop into the notches of the
sectors 00; and as the sectors move and carry away the blank or wire, the
finger grasps such blank to hold it in place until the pincers firmly engage
the same, after which as the sectors return to their normal position as shown in
Fig. 9, the finger g draws away from beneath the wire or blank in the pincers in
consequence of the pivot 32 of the finger being above the rock shaft P, and hence
the end of the finger describes an arc of a circle until its divergence causes the
end of the finger to separate from the wire or blank as held by the pincers, and the
spring 33 returns the finger to the normal position shown in Fig. 9.
It is advantageous to provide a clutch at p for connecting the driving pulley U
to the counter-shaft T and a lever p¹ for shifting the pulley to connect or disconnect

page_text: 5
the clutches and thereby stop or start the feeding mechanism of the machine ;
and it will be understood that when the feeding mechanism is stopped or thrown.
out of action, no harm results from the continuance of rotation of the swaging dies
