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 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 adjustable toggle-link, between the swaging-die, and the
roller-engaging block, as hereinafter set forth.
Fig. 1, represents a front elevation of the machine with the face plate removed.
Fig. 2, represents a side elevation and partial section.
Fig. 3, represents an enlarged transverse section, Fig. 4, an axial section, and
Fig. 5, a side view of the toggle-link which is interposed between the swaging-die
and the roller-engaging block.
Fig. 6, represents an enlarged detail view of the connecting head by means of
which the toggle-link is actuated to cause the opening or closing movement of
the die.
In the drawing, 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 a², a, which are held for
rotation in the cylindrical recesses a³, a³, and adapted for engagement with the
slidable blocks D, D, to cause the proper reciprocation of the dies E, E; the said
engaging blocks and dies, being loosely held in the diametrical groove j, made in
the enlarged forward end of the holding spindle B; aud between the dies E, E,
and the engaging blocks D, D, are placed the toggle-links F, F, the said links
consisting of the block a, ficting in the cylindrical recess or socket b, in the
block D, and the block a', fitting in the recess or socket ', in the die E, the said
blocks a and a', being connected to each other to form the toggle-link by means of
the cylindrical pin c, which fits into the cylindrically curved recess e, c¹, made in
the adjacent sides of the blocks a and a. The said blocks a and a', are secured
to each other, and to the pin c, by means of the washers d, d, which are placed
upon the projecting ends of the pin c, and are provided with the circular flange d',
which enters the circular grooves d², d², made in the ends of the blocks a, and a¹, to
receive the same, the parallel sides s, s, of the washers d, d, being held in the
recesses e, e, in the opposite sides of the opening f made in the head g, Fig. 6, so
that upon the movement of the said head g, back and forth, a corresponding
movement will be imparted to the central joint of the toggle-link F.
The head gis provided with a shank h, which passes loosely through a longitudinal
perforationi, made in the die-holding spindle B, and is secured to the sliding
sleeve G, the said sliding sleeve being provided with a groove k, in which is placed
the loose ring H, to which operative connection is made from a treadle, by means
of the toggle-jointed arms m, m', the arm m being jointed to the ring H, by means
of the screw n, and the arm m' jointed to the bearing standard o, of the head A,
by means of the screw n', and to the middle joint n is attached the downwardly
extending link P, which is connected with a treadle,-not shown in the drawing,-the
said link and treadle being caused to rise by means of a spiral or other suitable
spring 9, and upon the downward movement of the treadle by the operator of the
machine, the sleeve G will be thrown forward thus forcing forward the central

page_text: joints of the toggle-links F, F, and changing their inclination, whereby the
distance between the engaging blocks D, D, and the working faces of the dies E, E,
will be increased, so that the dies at the impact of the beating rollers a², a², will he
brought nearer together than before.
The several parts are held in position in the groove j, of the die-holding spindle,
by means of the face plate J, which is secured to the front face of the spindle B,
by means of screws. When the axes of the blocks a, a', and the pin c, are in the
same right line, as shown in Fig. 3, the dies will be carried to their extreme inward
position, and the toggle-links will transmit the impulse received from the beating-
rollers, to the dies, without lateral thrust, and a uniform beating distance will be
attained at the completion of the closing movement of the dies, upon the work,
which is an important feature.
Having now particularly described and ascertained the nature of my said
invention 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 intermediate toggle-links, and means for changing
the angle of the toggle-links while the machine is in operation, substantially as
described.
2. In a swaging-machine, the combination of the beaters, the swaging-dies, and
the engaging-blocks, with the intermediate toggle-links, and the slidable-heads for
changing the angle of the toggle-links while the machine is in operation, substan-
tially as described.
3. In a swaging-machine, the combination of the beaters, the swaging-dies, and
the engaging-blocks, with the toggle-links, provided at their central joints with the
cylindrical pin, and the washers which engage with the sides of the toggle-links,
substantially as described.
Dated this Twenty-fifth day of January 1895.
