Improvements in Feeding Devices for Machines for Making Rolled
Forgings.
I HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents
45 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:-
دو
My invention relates especially to means for rotating the "stock or metallic
bar from which rolled forgings are made and while in process of formation between
the dies; it being especially applicable for use with the rolled forging machines
wherein vertical rotary forming dies are employed.
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 a rolling machine showing my improvement in use;
and,
Figure 2 an end elevation of the same.
Like letters and figures of reference indicate corresponding parts in the different
figures of the drawings.
A represents the bed of the machine, and B C vertical standards thereon in which
the main shaft b, is journalled.
The forming dies df, are respectively secured on the inner face of a cylinder, D,
and disc E disposed on the shaft and connecting mechanism. A gear his disposed
on the shaft.
A vertical bracket or standard i is secured to the standard B and upon the bed, A
a vertical standard ; is disposed between the gears gh.
:
A horizontally arranged shaft k is journalled in the standards i j and bears a gear m
and pinion p
said pinion meshing with the gear h on the main machine.
Two rolls grare journalled at one end in bearings t in the standard i the bodies
of said rolls being supported in suitable bearings in the standard j; said rolls are
disposed in the same vertical plane and have their faces or surfaces corrugated or
indented.
The shaft of each roll is provided with a pinion w, which meshes with the gear m.
A horizontal arm & projects outwardly from the standard ; and pivoted in the said
arm is a bell-crank lever y, the vertical arm z of said lever being forked as shown in
Figure 1.
Journalled in the arms thus formed is a horizontal roll 15, arranged in the same
horizontal plane as the line of contact of the rolls q r.
A treadle 16 is hinged below the frame of the machine and an arm 17 connects
said treadle with the short arm of the said bell-crank lever.
It is not deemed essential in the present application for the purpose of illustrating
the uses of my improvement to describe the construction or operation of the main
portion of the machine.
The dies df have a vertical rotary and reciprocating movement and the bar H,
from which the forging formed is inserted horizontally between said dies.
Considerable difficulty has heretofore been experienced in supporting the said bar

page_text: in the proper position, and it has moreover been found that by rotating the same
much more perfect work could be effected.
In my improvement the gear while the main machine is in operation imparts a
rapid rotary movement to the corrugated rolls q, r.
The bar H, being inserted between the dies in the usual manner is in engagement
..with the surfaces of said rolls.
The treadle 16, is now depressed drawing down the short arm of the bell-crank
lever y and throwing the smooth roll, 15, inward against said har thereby holding it
firmly in position, the bar being thus forced against the revolving corrugated rolls a
rapid rotary movement is imparted thereto which greatly facilitates the action of the
dies upon said bar, H; the forging is thus formed. By releasing the treadle 16,
said bar may be moved forward between the dies and the operation repeated.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is :-
First. A feed device for rolled
geared to the die mechanism a
mechanism for forcing said roll
be held between said rolls and a
described.
forging machines comprising two corrugated roils
smooth roll mounted in a pivoted journal a treadle
into engagement with the stock whereby it may
rotary movement imparted thereto substantially as
Second. A rotary stock-feed for rolled forging machines comprising companion
rolls mounted in the same plane and actuated by the driving mechanism of the
machine, and a smooth roll mounted in pivoted journals and adapted to hold the
stock in engagement with said companion rolls substantially as described.
Third. In a device of the character described, the rolls or mounted on the body of
the machine and actuated by the driving mechanism thereof in combination with
the roll, 15, mounted in pivoted journals substantially as and for the purpose set
i forth.
Fourth. In a stock feeding device for rolled forging machines two roughened or
corrugated rolls journalled on the machine body adjacent to the forming dies and
actuated by the driving mechanism thereof in combination with a pivoted clamping
roll and mechanism for forcing said roll against the stock.
Fifth. In a machine for making rolled forgings the rolls q r journalled in the
machine-frame and geared to the die driving mechanism combined with the clamping
roll, 15, on the lever y the rod, 17, and treadle, 16 for actuating said lever all being
arranged to operate, substantially as and for the purpose set forth.
