Improvements in Machines for Making Rolled Forgings.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent Agents
Southampton Buildings in the County of Middlesex 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 :-
This invention relates to that class of machines for making rolled forgings in which
one forming die moves over or past the other while in contact with the bar being
acted upon; and it consists in certain novel features hereinafter fully set forth the
object being to produce a simpler, cheaper and more effective device of this character
than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all
conversant with such matters from the following explanation.
In the accompanying drawing
Figure 1 is a side elevation of the improved machine.
Figure 2 is a sectional elevation taken on line x, x of Figure 1.
Figure 3 is a similar view taken on the line y y of Figure 1 and
Figure 4 is an enlarged sectional view showing the formation of the working face
of the dies.
Like letters and figures of reference indicate corresponding parts in the different
figures of the drawing.
A represents the bench or framework of the machine which consists of a bed--
piece b, supported by standards or legs d, connected by braces f.
The bed or table b, is provided in its upper face with two longitudinally arranged
V-shaped tracks or grooves g, and centrally with a rectangular groove or track h.
A platen B, is provided in its under face with two V-shaped flanges i, fitted to work
in the tracks g, and centrally with a cross-sectional rectangular flange j, working in
the track h. The lower edge of the flange j, is toothed at k, forming a rack.
A horizontal rotating shaft 1, is journalled in the bench A, and a standard m, said
shaft bearing fast and loose pulleys p, q, whereby a reiprocating movement may be
imparted by means of a crossed and straight belt and stripper in the ordinary
manner.
A horizontal rotating shaft, is journalled centrally in the table 6, and bears a gear t
at its outer end meshing with a pinion on the shaft 1. A centrally arranged
pinion w, on the shaft meshes with the racks j, on the platen B.
A stub shaft 15, is journalled in a block 16, secured centrally to the rear edge of
the table b, said shaft bearing a pinion 17, meshing with a longitudinally arranged
rack 18, at the rear edge of the platen B.
A shaft 19 is journalled in standards, 20 and 21, secured centrally at the front and
rear edges of the table, said shaft bearing a large gear 22, which meshes with the
pinion 17. The bearing of the shaft 19, in the standard 21, is cushioned on a
spring 23, and is adjustable vertically by means of a set screw, 24, passing through the
top of said standard.
A horizontal die C, is secured to the face of the platen B, and consists of a bed-
piece 25, provided with a vertically inclined working face 26.
The face 26 comprises two cutting flanges or bosses 27, the outer edges of which
incline outwardly (see Figure 4) at 28, and diverge gradually from the lower end 29, of
said face to its highest end 30. The face between the bosses 27, is grooved longitudinally
at 31, to conform to the shape of the article to be formed (see Figure 4) said articles
being in the present instance a tool-handle.

page_text: A broad wheel 32 is secured to the shaft 19, and bears a die D, consisting of a
curved bed-plate 33, provided with a working face 35 constructed in the same form
and of the same size as the die C, said die D, being however, as shown, convex in
longitudinal section.
The dies are disposed in the same vertical plane with their cutting bosses 27,
and 36, registering, the ends 29, and 30, of the die C, being disposed diametrically
opposite the corresponding ends 37, and 38, of the die D, and their working faces
being of the same length.
In the use of this improvement, the shaft 1, being set in motion rotates the shaft r,
and drives the platen B, horizontally in the tracks g. As the platen moves the
rack 18, rotates the shaft 19, and causes the die wheel 32, to revolve in a direction
opposite to that in which the platen moves.
A bar from which the forging is to be rolled, after being properly heated is
passed through an opening 40, in the standard 21, which serves as a guide therefor,
and laterally between the dies C, D, as their ends 29, and 37, of their respective
working faces approach each other.
The cutting bosses of the dies engage said bar on opposite sides and as they pass
each other form the handle 50, or other article to which the dies are adapted, in a
manner readily understood by all conversant with such matters. The bar is rotated
by the action of the dies as they pass. By indenting or corrugating the bevelled
spreading faces 28 of the bosses, as shown in Fig. 4 this rotation is made more
regular, and the article thus formed is more perfect in shape.
The bosses bisect the bar at each end of the forging, a waste piece 51, falling on to
the platen from which it may readily be removed."
One end of the shaft 19, resting on the spring 23, depresses it slightly when not in
action thus affording sufficient play to easily insert the bar.
The reciprocating movement completes the formation of the article much more
perfectly than when the wheel completely revolves, and avoids the necessity of directing
the bar for the subsequent movements of the dies.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me
