Street, Providence, County of Providence and State of Rhode Island, United
States of America, Machinist.]
Improvements in Rotary Swaging Machines.
I, CHARLES HOWE STOCKS of 213 Deansgate, Manchester, Engineer, do
hereby declare the nature of my said invention to be as follows:-
These improvements refer to rotary swaging machines for compressing,
hanımering and similarly treating objects of metal, and relate more particularly to
the swaging machine for which Antoine Jean Langelier obtained Letters Patent
No. 1461 on the 25th day of January 1892. The object of the present improve-
ments is to facilitate the adjustment of the jaws or dies when it is required to give
them a greater or lesser range of movement which has hitherto been effected by
screwing a couple of conical pointed screws through a plate out or into conical
but this arrangement is somewhat defective in that it is difficult to set
both dies alike and the screws are liable to work loose in running the machine.
In accordance with my invention I employ die blocks and followers enclosed
within the slotted end of a tubular driving shaft as described in the Specification
aforesaid, but in that end of each follower which comes in contact with the
hardened steel rolls I fit a single steel roll, of even diameter for the full width of
the follower, but having a reduced portion projecting beyond the front end of the
follower.
recesses,
These reduced portions are designed to take into notches formed in the opposite
edges of two plates or "shoes" fitted in the rear side of an annular ring or plate
(hereinafter called the adjusting ring) which is secured by screws, passing through
elongated slots, to the front end of the tubular shaft.
The "shoes" aforesaid are capable of sliding to and fro in straight parallel
grooves in the back of the adjusting ring, the edge of each slide with the notch in
being flush with the inner circumference of the ring and therefore tangent thereto
and each of said notches being open towards each other.
"
It will now be seen that to adjust the dies so as to give say a greater range of
movement or allow them to act upon an object of increased diameter the adjusting
ring, after loosening the screws is turned round, say to the right, on the end of the
shaft (the elongated slots allowing for this) to the extent which will cause the
"shoes
in the rear face thereof to move along their grooves, so increasing
the distance between the two notches. This being effected the clamping screws
are tightened up and the dies have an increase of range equal to the increased
distance between the notches in the sliding "shoes" which is caused by the tangential
setting of the groove.
By turning the adjusting ring to the left it will be clear that the range of
movement of the dies will be lessened owing to the notches being brought closer
together.
The notch in each "shoe" is sufficiently deep for the reduced portions on the rolls
in the followers to always remain in the same.
It will be obvious that instead of the reduced ends of the follower rolls taking
into the notches in the sliding shoes, the same may be made to fit directly into the

page_text: slots, or the followers themselves may be made to take into such slots or grooves,
the rolls aforesaid being dispensed with.

I, CHARLES HOWE STOCKS, of 213 Deansgate, Manchester, Engineer, do
hereby declare the nature of my said invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:—
These improvements refer to rotary swaging machines for compressing,
hammering and similarly treating objects of metal, and relate more particularly to
the swaging machine for which Antoine Jean Langelier obtained Letters Patent
No. 1461 on the 25th day of January 1892. The object of the present improve-
ments is to facilitate the adjustment of the jaws or dies when it is required to give
them a greater or lesser range of movement which has hitherto been effected by
screwing a couple of conical pointed screws through a plate out or into conical
recesses, but this arrangement is somewhat defective in that it is difficult to set
both dies alike and the screws are liable to work loose in running the machine.
And in order that my said invention shall be the more readily understood and
carried into practical effect I have hereunto annexed a sheet of drawings and will
now proceed to describe the same with the assistance of the various figures and
letters of reference marked thereon.
Fig. 1 is an end view (with the cover plate removed to shew the parts to which
my invention applies more clearly) and Fig. 2 is a side sectional view of my
improved swaging machine. Fig. 3 is a rear view of the adjusting ring hereinafter
described.
In accordance with my invention I employ die blocks A, A and followers B
enclosed within the slotted end of a tubular driving shaft C as described in the
Specification aforesaid, but in that end of each follower which comes in contact
with the hardened steel rolls D I fit a single steel roll E of even diameter for the
full width of the follower, but having a reduced portion F projecting beyond the
front end of the follower.

These reduced portions take into notches or recesses G formed in the opposite
edges of two plates or "shoes" H (see Fig. 3) fitted in the rear side of an annular
ring or plate I (hereinafter called the adjusting ring) which is secured by clamping
screws passing through elongated slots J to the front end of the tubular shaft C.
The shoes"H are capable of sliding to and fro in straight parallel grooves K
in the back of the adjusting ring I the edge of each slide with the notch G being
flush with the inner circumference of the ring I as illustrated and therefore tangent
thereto and each of said notches is open towards the other. The grooves K are
normally at right angles with the line of dies and followers and on turning the
ring the grooves K alter their angle and therefore alter the distance between the
two notches G in the shoes H which are held stationary by the rolls E. Assuming
now that the grooves K are in their normal position with the rolls E at their
closest position and it is desired to adjust the die blocks A so as to give a greater
range of movement or allow them to act upon an object of increased size or
diameter, the adjusting ring 1, after loosening the clamping screws aforesaid is
turned round in the direction of the arrow X on the end of the shaft C (the
elongated slots J allowing for this) to an extent which will cause the "shoes" H in
the rear faces thereof to move along their grooves in opposite directions until the

page_text: desired increased distance between the two notches G is obtained, say as shewn in
Fig. 2. This adjustment having been effected the clamping screws are tightened
up and the die blocks have an increase of range equal to the increased distance
between the notches in the sliding "shoes."
By turning the adjusting ring in the opposite direction it will be clear that the
range of movement of the dies will be lessened owing to the notches being brought
closer together.
The notch in each "shoe" is sufficiently deep for the reduced portions on the
rolls in the followers to always remain in the same.
It will be obvious that instead of the reduced ends of the follower rolls taking
into the notches in the sliding shoes the same may be made to fit directly into the
slots, or the followers themselves may be made to take into such slots or grooves,
the rolls aforesaid being dispensed with.
Having thus particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1st. In rotary swaging machines the use and employment of the adjusting ring I
with parallel grooves K acting upon rolls E in followers B or directly upon the
said followers, substantially as and for the purposes hereinbefore described and
illustrated on the accompanying drawings.
2nd. In rotary swaging machines the use and employment of followers B fitted
with rolls E with reduced portions F engaging with slides or "shoes" H in parallel
grooves K of a ring or plate I and mounted and operating substantially as and for
the purposes herein before described and illustrated on the accompanying drawings.
3rd. The combination and arrangement of mechanism herein before described for
effecting the adjustment of the dies of rotary and similar swaging machines as set
forth.
