Improvements in Swaging Machines.
ARTHUR JACOB MORSE, of the Town of Salisbury, in the County of Litchfield,
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 performed, to
be particularly described and ascertained, in and by the following statement:
-
My invention relates to improvements in Swaging Machines for swaging
bicycle spokes, needles and analogous articles, and the object is to provide means
whereby the cams or tappets may be quickly, equally and simultaneously adjusted,
and the friction decreased between said cams or tappets and the die blocks or
backers.
To this end my invention consists in the combination with the stationary
cylindrical shell, of a circular series of cams movable radially in grooves in said
shell, an adjustable ring mounted on the shell, and provided with a series of
inclined recesses to engage the cams, a cylindrical shaft in said shell carrying a
rotary head containing a groove, a pair of dies, and a pair of die-blocks in said
groove, and a roller in each die block to engage the cams.
And my invention consists also in certain other combinations of parts herein-
after described and specifically set forth in the claims.
In the Drawings hereto annexed and forming a part of this specification, Figure 1
is a side elevation partly in section of my improved swaging machine, Figure 2 is
a face view of the rotary head, Figure 3 is a side elevation of the rotary head
removed from the shell, Figure 4 shows a face view of the dies, die blocks and
rollers removed from the head, Figure 5 shows dies and die-blocks without rollers,
Figure 6 is an enlarged face view of the head of the swaging machine with the
face plates removed, and Figure 7 shows the same with the face plates and the
adjustable plate secured thereto.
Referring specifically to the Drawings, A is the stationary cylindrical shell or
casting, one end of which is expanded to contain the rotatable head; B₁ is the
rotatable head, and B is the cylindrical driving shaft of the head, which extends
horizontally and longitudinally within the shell. Across the end of the said head
is a mortise or groove, and in the groove is a pair of sliding dies, b, b, a pair of
die blocks or backers, 61, 61, and a roller, c, in each die-block to engage the beveled
ends of the cams, a, a, etc.
In order to secure the dies, die-blocks and rollers in the groove of the head, B',
I secure a small plate, d, to the face of the head over the groove. This plate, d,
is shown let into the head so that its face is flush with that of the head.
In the face of the expanded end of the shell are a series of radial grooves and in
these grooves are the movable tappets or cams, a, a, etc.
The inner ends of the cams are beveled or inclined and engage the small
rollers, c, c, in the ends of the die-blocks. The outer ends of the cams are also
beveled and engage the series of inclined surfaces or recesses, a¹, a¹, etc., formed
on the inner surface of the adjustable ring, C, mounted on the periphery of the
expanded portion of the shell. Said recesses in the ring are all inclined in the

page_text: -
same direction corresponding with the beveled ends of the cams, so that when it
becomes necessary to move the cams toward the rotary head more or less this may
be accomplished by moving or rotating the ring, C, upon the shell. To effect this
movement easily, I preferably provide the ring with a lug, D, to which is attached
a handle D. The unfeathered arrow near the lug indicates the direction of move-
ment of the ring when the cams are forced toward the center.
It will be obvious that by these means the cams will be moved simultaneously
and equally.
In order to secure the cams, a, a, etc., in the grooves, I secure by means of
screws or bolts, a pair of ring-shaped face-plates, E, F, to the face of the stationary
head. The face-plates differ in size and are concentric with each other.
Between the said face-plates is an adjustable .ring-shaped face plate, G, provided
with a series of slots, c, equal in number to the cams.
These slots engage the cams, a, by means of pins, f, projecting from the cams
and entering the slots. The slots are slightly curved and tangential, so that when
the plate is rotated with the ring, C, to which it is connected by a lug, y, and
screw, g¹, passing through a slot, h, in the face-plate, E, it will also aid in moving
the cams, a, a, etc. The movable face-plates serve to move the cams outward away
from the center when the ring, C, is moved in the direction to permit of such move-
ment. Plate, G, is provided with beveled edges which engage beveled edges on
the stationary plates.
'
During the revolution of the head, there are as many closures of the dies each
revolution of the shaft as there are tappets or cams in the circular series. The
cams are diametrically opposite each other and this insures a stroke upon both die-
blocks or backers, simultaneously.
I preferably provide the die-blocks with the rollers, c, c, as they decrease the
friction to a considerable. degree, but I do not desire to be limited to them as 'the
die-blocks themselves may be provided with curved ends, as shown in Figure 5
and directly engage the cams.
In Figure 1, H is the driving pulley, and I is the loose pulley on the shaft B.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1
1. In a swaging machine, the combination with the stationary cylindrical shell,
of a circular series of cams movable radially in grooves in said shell, an adjustable
ring mounted on the shell and provided with a series of inclined faces to engage
the cams, a stationary face plate to retain the cams in their grooves, an adjustable
face plate provided with tangential slots, pins projecting from the cams and
entering the slots, a rotary shaft carrying a head with a groove and dies and die-
blocks in the groove, as set forth.
:
2. In a swaging machine, the combination with the stationary cylindrical shell, of
a circular series of cams movable radially in grooves in said shell an adjustable ring
mounted on the shell and provided with a series of inclined faces to engage the
cams, a stationary face-plate to retain the cams in their grooves, an adjustable
face plate provided with tangential slots, pins projecting from the cams and enter-
ing the slots, a connection between the adjustable face plate and the adjustable
ring, means carried by the said ring for moving the same, a rotary shaft carrying
a head with a groove and dies and die-blocks in the groove adapted to be operated
by the cams, as set forth.

3. In a swaging machine, the combination with the stationary cylindrical shell,
of a circular series of cams movable radially in grooves in said shell, an adjustable
ring mounted on the shell and provided with a series of inclined faces to engage
the cams, a pair of stationary concentric face-plates to retain the cams, a circular
adjustable face-plate between the stationary plates, said adjustable plate having
tangential bearing surfaces, pins projecting from the cams and engaging the said
