Improvements in Swaging Machines.
I, ANTOINE JEAN LANGELIER, of 58 Dexter Street, in the City of
Providence, State of Rhode Island, 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 the improved means employed to effect a closing or
opening movement of the swaging dies, while the machine is in operation; and it
consists in the employment of an angularly adjustable block, and a slidable-shoe,
between the swaging-die and the engaging-block, as hereinafter fully set forth.
In the accompanying drawings:
Fig. 1, represents a front elevation of the machine, with the front plates
removed.
Fig. 2, represents a side elevation and a partial section..
. "
Fig. 3, represents an axial section of the die-holding spindle, showing a
modification.
Fig. 4, represents an axial section of the die-holding spindle, showing another
modification.
In the drawings, A represents the stationary head, in which is journalled the
die-holding spindle B, to which rotary motion is imparted by means of the pulley C.
The head A is provided with the beating-rollers a, a, which are held for rotation
in the cylindrical recesses a¹, a', and adapted for engagement with the sliding
hlocks D, D, to cause the proper reciprocation of the swaging-dies E, E, the said
engaging-blocks and swaging dies being loosely held in the diametrical groovej,
made in the enlarged forward end of the holding spindle B; and between the
swaging dies E, and the engaging blocks D, in the groovej, are placed the angularly
adjustable blocks F, F, having rounded ends and provided at their inner rounded
ends with a slidable-shoe G, by the movement of which the distance between the
working faces of the swaging-dies, and the engaging-blocks, may be either increased
or diminished, to the limited extent required. The enlarged forward end portion
of the die-holding spindle B, is provided with the perforations b, b, adapted to
receive the parallel rods, e, which at their forward ends bear against the rear
edge of the slidable shoe G, and are secured at their rearward ends to the sliding
sleeve H, to which operative connection is made by means of the ring I, fitting loosely
in the circumferential groove d of the sleeve; and connection is made from the
ring I, to an operating treadle-not shown in the drawing-by means of the toggle-
jointed arms e, e', the arm e, being jointed to the ring I, by means of the screw f
and the arm el jointed to the bearing standard g, of the head A, by means of the
screw ; and to the middle joint, is attached the downwardly extending link h,
which is connected with the treadle, the said link and treadle being caused to rise
by means of a spiral or other suitable spring i; and upon the downward movement
of the treadle by the operator of the machine, the sleeve H will be thrown forward,
thus forcing forward the slidable-shoe G, and changing the angular position of the
blocks F, F, thus increasing the distance between the swaging dies E, and the
engaging blocks D, so that the dies will be brought closer together upon
the engaging impulse of the beating rollers a. The several parts are held in
position in the groovej of the dic-holding spindle. by means of the face plate J
which is secured to the front face of the spindle by means of screws, and a reverse

page_text: inovement is imparted to the slidable shoes G by means of the spring I, secured to
the front of the face plate J, which springs act upon the projecting forward ends
of the said shoes.
A modification of my invention is shown in Fig. 4, in which the slidable shoes G,
are shown at the outer instead of the inner end of the angularly adjustable
blocks F, F, and in this case the desired movement of the shoes is produced by
means of the bell-crank levers m, which are connected by means of the links n, with
the rods, which rods are connected with the sliding-sleeve H; and upon the forward
movement of the sleeve H, the swaging dies will be brought closer together, as
before.
Another modification is shown in Fig. 3, in which the angularly adjustable
blocks F, F, are provided with a rearwardly extending arm k, to which the links
are connected, and in this case, the springs for operating the shoes in the reverse
direction, may be dispensed with, the said angularly adjustable blocks being
positively connected with the sleeve H, so as to be operated thereby in both
directions.
Having now particularly described and ascertained the nature of ny said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In a swaging-machine, the combination of the beaters, the swaging-dies, and
the engaging-blocks, with the angularly adjustable-blocks and means for changing
the direction of the axes of the adjustable-blocks while the machine is in operation,
substantially as described.
2. In a swaging-machine, the combination of the stationary head, and the
beaters, with the rotary spindle provided with the engaging-blocks, the swaging
dies, the angularly adjustable-blocks, the slidable-shoes and means for changing
the direction of the axes of the adjustable-blocks, while the machine is in operation,
substantially as described.
