Improvements in Metal Rolling Machines.
I, DANIEL EDGAR KEMPSTER of Boston in the County of Suffolk State of Massa-
chusetts United States of America, Inventor 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 organized system or automatic metal-rolling mill original
with me, and broadly covered by my complete application for British Letters Patent filed
Septr. 7th 1888 No. 12951 and No. 12952 wherein metal articles having circular cross
sectional area are formed or forged directly from a continuous rod or coil of wire or
from automatically fed bars or blanks without any intervening maiphlation by hand as
practiced prior to my invention; and when said invention is applied to the manu-
facture of steel spheres or conical,steel rifle bullets, as shown in the drawings herewith,
or in fact to any small circular metal articles of large consumption, they may be
produced more spee lily and economically than by any previously known method, and,
if desired, fully hardened or tempered for use direct from the rolling mill.
The object of my present invention is to improve the construction and arrangement
of the various elements or devices constituting said system or mill as a whole, whereby
I am able to more easily adjust and control their operations and also, when necessary,
more readily replace the dies, cutters, feed-rolls, and metai rod or bar being worked,
these being the parts requiring repairs or renewal the most frequently; also, in my
present horizontal arrangement of these devices the scale from the hot metal rod or
blank as it passes out of the furnace falls to the floor and is not liable to be rolled into
the article being forget; and, also the rolling-machine and its rod-supporting reel
are both made independent from the furnace or heating apparatus, and when necessary
can be quickly separated therefrom or from each other to admit of building a new
furnace or for making any needed repairs upon either one of the said devices.
My present invention consists in the special construction of the various elements
or devices herein set forth, and also in the combinations of said elements or devices
which thereby constitute my improved metal-rolling mill, and one more adapted to
meet the requirements of a general manufacture of metal articles circular in cross-
sectional area, but having varied longitudinal configuration, than the original metal-
rolling mill, before referred to, as will now be fully described, and specially pointed
out in the claims.
In the drawings, and in which similar figures and letters of reference indicate
corresponding paris wherever they occur thereon,
Figure 1, is a side elevation of my improved metal-rolling mill.

For a general class of work I find it convenient to construct and arrange the mill
in the manner shown in the accompanying drawings, in which (a) represents a suit-
able base or bed having legs 22, and supported on carrying wheels 3 3 3 3, which
hami thoin front ends hent unwardly and

page_text: to be struck and lifted by the pins 7 7, on the front leg of the machine when it is run
up close to the furnace for action, the hooked pawls dropping down over said pins and
holding said, machine rigidly in place. When necessary to run the machine back
out of the way, the hooked pawls may be disengaged by pressing the foot upon the
treadle S.
A dic-carrier, 9, in the form of a-wheel or disk is fast on-a-shaft, 10, free to revolve
in suitable bearings in a supporting-frame, (b) forming a part of the bed (a) by being
securely fastened thereon by screws 11 11 11. The die carrier, 9. revolves within the
frame () said frame being connected both over the top and also in front of said die-
carrier, (see Figs. 2 and 3) its two sides being thus strongly tied together, which
effectually prevents the casting or frame from springing apart when the dies are
doing their work. On the inner face of the disc or die carrier 9, one or more
in the present case three curved plate or platen dies, 12 12 12, are shown fastened
by suitable screws, 13 13 13. The curve of said dies corresponds to the radius of
said die-carrier, and their length is about one-fourth of the circumference thereof,
thus leaving a space between said dies for the finished article to drop cut. (See
Figs. 1 & 4.)
The frame () is so shaped as to embrace a little more than a quarter of the
die-carrier 9, and has pivoted thereon anti-frictional rollers 14 14, running against
said carrier-back, and thus supporting and effectually preventing said carrier or
disk from springing when the dies are rolling metal. (See Figs. 2 and 3.)
On the frame () at the left of the die carrier is a stationary plate or platen die, 15,
substantially similar to the revolving dies 12, and rigidly fastened by suitable
screws, 16 16 16, passing through said frame." A curved wedge, 17, interposed
between said die 15 and frame () is provided on its outer edge with gear-teeth 18,
meshing into a worm, 19, on a short shaft running loosely in a suitable bearing
in an car on the inner side of the main frame. The worm-shaft has a small wheel
or crank, whereby said worm my be revolved and thus cause the wedge 17 to move
in a circle and thereby move the stationary die 15 laterally to adjust the distance
between the adjacent working-faces of said dies 12 and 15. If desired, a graduated
dial having a pointer may be connected with said wedge-adjusting worm-crank, and
thus facilitate a fine and accurate adjustment of the dies, as required for certain
kinds of work.
The wedge 17 is slotted where the screws 16 pass through it to permit its longi-
tudinal or circular movement, said screws clamping the die and its wedge rigidly to
the frame after the proper adjustment of said die. (See Figs. 1, 2, and 3.) The
dies 12 and 15 are curved plates or platens parallel from end to end and having
working grooves formed longitudinally within the parallel faces thereof, thus forming
grooves (the entire length of said dies) which are properly shaped and tapered, and
have forming, reducing, and spreading sufaces adapted to roll-forge the blank
interposed between them into the finished article desired, said dies being milled
or scored, as at (e) in Figs. 1 and 4, to aid in rotating the blank in the usual
manner.
It will be observed that the dies 12 and 15 are not cut away tapering on their faces,
(as is usual with dies adapted to roll-forge metal articles on the end of a rod or bar
which rotates with the article being forged, and thereby holds said articles in proper
position between said dies during the forging operation,) but are formed parallel from
end to end, their faces being flush with the top of the working grooves therein, thus
bodily confining (see Fig. 6) the metal blank separated from the rod or bar from the
first start, and holding and guiding and keeping it in proper position during its
planetary travel in the forging operation without depending at all-upon the main rod
or bar from which it was severed.
For forging certain kinds of work in my present form of rolling-mill, I may use
dies having working grooves wherein the metal reducing, spreading and forming
surfaces of the die are all located within a working-groove formed obliquely to the
plane or line of movement of said die, and thereby imparting superior qualities to the
article being forged, as is fully explained in my said applications of 1888.

page_text: On the front of the frame (b) at the left and just above the stationary die 15, is
secured a cut-off stand c, fastened to said frame by suitable screws, 20 21. The
bottom of the stand (c) and its seat on the frame (b) are suitably grooved and tongued
together, so as to hold said stand square with the frame and yet admit of a certain
amount of horizontal or fore-and-aft adjustment thereof, to enable the position of
the cutters to be varied with relation to the dies being used, as is frequently required
in forging different articles. The stand (c) is slotted for the screw 20 to pass through,
and by slackening said screw slightly said stand and its cutters may be very finely
adjusted by turning the screw 21 in or out, as will be readily understood by referring
to Figs. 1, 2, and 3. The said stand has a cutter-bar, 22, arranged to reciprocate
freely within and across the former, and provided with a groove for the reception
of the cutter 23, held therein by screw 24 and adjusted by screw 25.
Said
bar has on its outer end a suitable sind and roll adapted to work within a slot in
one end of the rocker-lever 26. freely vibrating in the stand 27, fast on the side of
the machine, the other end of said lever having a stud and roll adapted to work
within a grooved cam 28, on the shaft 10 held by suitable screws or otherwise.
Said cam 28 has a corresponding number of rises or throws as there are dies on the
revolving die-carrier.
On the stand (c) a projecting arm extending upwardly over the centre of the
machine has a vertical cutter 29, securely clamped therein by screw 30.
slackening said screw slightly the cutter may be moved or adjustel as required.
By
On the front of the machine or frame (b) is pivoted a lever or moving guide, 31,
through which passes the metal rod or bar 32, and is supported and guided thereby,
A coiled spring 38, holds said guide in a normal position against the left hand
adjusting-screw 34 in one of the frame ears, and while in this position the metal rod
may be fed in past, the cutter 29 sufficient for the length of blank required. (See
Fig. 3). When the cutter is cutting said blank from the rod, said rod and its
guide 31 are carried by said cutter over to the right far enough to completely sever
said rod, when the guide 31 will instantly be thrown by the spring 33 back into its
normal position, thus clearing the end of the metal rod from the front side of the
cutter 29 preparatory to feeding in said guide another length of blank. The adjusting
screw 35 in the right-hand frame ear acts as a stop and prevents the moving guide 31
from throwing too far. The cutter 23 moyes past the cutter 29 far enough to carry
the severed metal blank across the end of the stationary die 15 and against the face
of the moving die 12 on the revolving carrier, (see Fig. 2.) when it is instantly
rolled down in between the tapering ends of the moving and stationary die faces,
where it is compelled to rotate about its own center and also travel with the moving
die in a planetary manner about the ie-carrier shaft until it falls out at the bottom of
the machine into the cooler receptacle 38 completely rolled or forged into the required
shape of the finished article.
The cooler 36 consists of a flaring-mouthed casting under the machine and con-
nected to a cold-air blast pipe 37, having a suitable controlling damper or valve (m).
Said cooler is provided with a removable receptacle, 38, having suitable handles, and
its bottom perforated or made of woven wire, so the air will freely circulate but yet
retain the smallest metal forgings.
(d) is the feed-stand, secured fast by suitable screws, 39 39, on the front end of
the bed (a) and having its bottom or foot suitably tongued to fit a groove in the top
of said bed and thus be held square thereon, the stand being slotted for said fastening-
screws to pass through and adinit of a certain amount of longitudinal or fore-and-aft
adjustment being given said stand when required. The construction of some of the
mechanism composing said feed-stand is very similar to that contained in my former
application for patent No. 12952 of 1888, and I need not minutely describe its minor
parts.
Two corrugated feed-rolls, 41 41, are keyed fast on the ends of the two shafts 42 43,
suitably supported in bearings within said feed-stand and held apart by the spring 44.
In the top of said stand are suitable adjusting-screws 45 45, for pressing the feed-rolls
together, so as to grip the metal rod more closely as it draws said rod along between

page_text: their grooved faces. The feed-shafts are geared together by gears 46 46, fast thereon,
and having solid collars adapted to run together with sufficient frictional contact, to
prevent any lost motion or slack of the feeding mechanism when running the mill at
à high rate of speed.
Pivoted on the side of the feed stand is a gear 47, closely meshing with the lower
gear 46, and having a notched disk, 48, and feed-ratchet 49 connected therewith, so
as to all revolve together. The said notched disk is engaged by a detent 50, pivoted
on the stand and held by the coiled spring 51 thereon closely in contact with said
disk, and has projecting out from its side a pin or projection, 52. A long hooked
feed-pawl, 53, pivoted to the upright slotted lever 54, pivoted on the side of the bed
of the machine, is adapted to engage with said ratchet, and its free end is situated
between the ratchet and said detent pin or projection. (See Figs. 1 and 2) The
pawl 53 is supported in a slotted arm, 55, fastened by suitable screws 56 56, on the
bed of the machine, and is held up in proper working contact with its ratch t 49
by the spring 57 in said slotted arm. A cam lever 58, pivoted on said arm, (See
Figs. 1 and 3) is adapted to be swung across over the top of said pawl 53, so as
to depress it and throw it out of engagement with its ratchet 49, and also cause it
to strike the pin or projection 52 and throw out and hold the detent from engagement
with its notched disk 48; and while the cam lever remains in this position the feed
rolls may be revolved in either direction by hand with the use of à suitable crank
applied on the end of the feed shaft 45, which is properly squared therefor. (See
Fig. 5.)
The pivoted upright lever 54 has on its upper end a stud and roll adapted to
work within a grooved feed-cam 59, adjustably held by suitable screws (iii) having
slots therefor to the side of the cut off cam 28 on the shaft 10 said shaft having fast
ou its end a suitable driving pulley, 60, for operating the mill. The feed-cam 59 has
a corresponding number of rises or throws as there are dies on the revolving die-
carrier and rises or throws on the cut off cam 28, said dies, feed-cam, and cut-off
cam being arranged and combined with each other and properly timed for automatic
and conjoint operation, the cut-off cam being adjusted and held by the screw () in
such position on its shaft with relation to the revolving dies on the disk or carrier
that the cutter 23 will carry the several blanks (a) against the starting or tapering
end of said dies (See fig. 2) just at the instant they have passed behind said blank a
distance equal to the diameter of the metal rod, the dies generally being tapered
enough to admit of the full-size blanks entering freely between their faces at the
starting ends thereof, and the feed-cam being adjusted and held in position on and
with relation to the cut-off cam, so that the feed lever will on the instant the cutter 23
has returned back to its normal position be caused to start to draw the feed pawl
backward and revolve its ratchet, and through the medium of the connected gearing
revolve the feed rolls and feed the metal rod forward into the machine, stopping its
movement just before the cutter 23 starts to move forward to sever another blank
therefrom. The longitudinal movement of said rod is prevented while the blank is
being cut off and the pawl returned forward, preparatory to engaging another tooth
of its ratchet by the spring-actuated detent resting in one of the notches of its disk,
thus securely holding the feed stationary for the time-specified.
By changing the feed-ratchet and notched disk for others having a different number
of teeth and varying the throw of the feeding pawl, if necessary, by adjusting its
pivotal stud in the slotted lever operated. by the feed cam, more or less metal rod inay
be put into the blank, as required for different sized articles, the feed rolls being also
of a size to feed in a metai rod of proper diameter therefor, depending of course
upon the shape and depth, of the configuration of the working grooves in the faces of
the dies employed.
In front of the rolling machine, supported upon a base or suitable legs securely
fastened to the floor, is a beating furnace, (e) having a hollow fire space extending
through it horizontally from end to end. Said furnace is preferably formed with a
suitably-molded fire-brick-core having the necessary apertures for fire-space, passage
of metal rod, entrance of blow-pipe, vent, &c., and is bricked up outside and held

page_text: together by metal end plates connected by suitable bolts, as shown. Said end plates
have auxiliary plates or nozzles 6161, perforated for the passage through of the metal
rod and detachably fastened to the main plates, so as to be readily removed and
replaced when worn or burned out. A powerful blow-pipe composed of the gas-
pipe 62 and air-blast pipe 63, each having suitable controlling cocks or valves (n)
enters through said furnace at the side on an angle, so as to drive the flame and heat
toward the front, the nozzle 61 at that end being shaped to concentrate the heat
around the metal rod 32, passing through it.
In the rear of the furnace and pivotally supported on a suitable standard, 64,
having a pedestal or base heavy enough to sustain itself in an upright position, is
a reel, (7) having arms 65 for supporting the coil of metal rod 32, said arms being
provided with adjustable upright pins 66, which are embraced by the said metal coil,
which is thus held in a central position thereon, said reel being adjusted as to its
height from the floor to coincide with the level bottom of the fire space within the
furnace and the center of the machine between the feed roll, thus retaining and
supporting the metal rod always in substantially a straight and horizontal position,
as required to prevent it from sagging and becoming clogged while at a white
heat within the furnace, which would result in the metal being burned; also, the
horizontal position of the rod while being fel along through the furnace permits the
scale from said hot rod to fall to the floor before reaching the metal rolling dies and
becoming rolled into the article being forged thereby.
It will be evident to a mechanic, or to those skilled in the art to which this'
invention appertains, that I may somewhat modify or vary the shape or construction
of the various devices composing the several elements herein combined for conjoint
operation, and I may also vary the arrangement or grouping of said elements in
combination to best adapt the mill to roll or forge the class of work required, all
without departing from the essential features and spirit of my invention. As, for
instance, the dies inay be made in different forms. One may be concaved plate or
bar and its its co-operating' die convex or a roll; or the dies may be made either
segmental or straight plates or any other known form, instead of being made
curved, as herein shown, any of said forms being old and well known mechanical
devices; also, if preferred, both of the dies may have movement when rolling metal,
although I prefer to have one die stationary, as herein described, as the cut-off
or blank-severing mechanism is more easily incorporated with said dies in a machine
so as to conjointly operate, and the article being rolled or forged is also more rapidly
carried out of the way of the next succeeding one; and, furthermore, with this
construction I can obtain a more gradual feed with any given speed of the
machine, as I am able to make use of all the time between the strokes of the cut-off
feeding in the metal rod for the next succeeding blank to be severed therefrom,
thereby admitting of running the mill at a much faster speed; also, with my
present construction, or having a series of moving dies working against a single
co-operating stationary die, as described, before one blank is completely formed
therein another blank starts into said dies to commence to be rolled thereby, thus
making one blank at least at all times being rolled or forged on the stationary
die. This makes the metal-rolling process continuous, similar to that in my former
applications Nos. 12951 and 12952 of 1888, in which die-rolls having duplex working
grooves are used.
When the mill is running on certain kinds of work formed from soft metal, the
furnace may be dispensed with, and in some cases the cutters also, the blanks being
previously all cut to length and fed automatically into the dies; or the mill may be
arranged vertically, and in that case the blanks when cut from the rod would drop by
gravity into the dies, avoiding any blank-feeding mechanism. Furthermore, the dies
in some cases may be so shaped as to automatically draw in the metal rod and by
compression sever the blank therefrom, and in that case both the cut-off and the
rod-feeding mechanisms would be dispensed with. Now, therefore, it must be seen
that I may modify the arrangement of my mill to best suit the class of work being
formed therein, but retain the principal and essential feature, which is the automatic

page_text: or continuously operating system of cross rolling or forging metal articles having
circular cross-sectional area (either singly or in series) direct from the coil of wire or
continuous blank-rod or from a supply of metal blanks, the entire operation, being
automatic and without any manipulation by hand, as heretofore, practiced prior to my
invention.
It is obvious that the movable dises might be formed convexed, so as to be placed
on the outer face or periphery of the die-carrier and work against a co-operating
concaved stationary die, if so preferred.
It is also apparent to any ordinary mechanic thai: any form of dies employed
for roll-forging metal in the manner herein referred to may have one or a series
of working grooves formed in its face, as it requires no invention to duplicate the
die-grooves.
Forging netal into various shapes by cross-rolling it between dies is an old and
well known.art, and needs no special description herein.
In view of the foregoing description and the state of the art as shown in my
former applications 12,951 and 12,952 of 1888, the operation of my improved metal-
rolling mill must be readily understood and I will simply state that the metal rod
passes from the reel or support through the heating furnace, and is heated
sufficiently for forging, and is fed into the machine by the intermittingly-revolving
feed-rolls, where the hot-metal blanks are severed therefrom by the intermittingly-
operating cutters, and are then carried into the dies, where they are both rolled or
forged, and also bodily carried along in the direction of the travel of the moving die
until they drop out finished articles into the cooler under the machine, when they are
quickly cooled by the cold-air blast which is forced up around and among them
continuously, and when the receptacle becomes filled with the forged articles it may
be removed and replaced by an empty one. If preferred, a tank of liquid for scaling
and hardening or tempering the metal forgings direct from the dies, may be used
instead of the air-blast, and it would be preferable when forging conical steel bullets,
as represented in the drawings herewith."
When heating up the furnace preparatory to the insertion of the metal rod, the
rolling-machine may be run back on its track out of the way and beat until said
furnace is sufficiently hot to start up the mill.
By having the large gear 47 on the feed stand connecting, so as to revolve the
smaller gears, 46, and having the feed-ratchet 49 rigidly connected with said gear 47,
so as to be revolved together, I am able to feed into the machine a long length of the
metal rod, by more or less revolution of the feed-rolls, with comparatively a short
throw of the feed-pawl, which is very desirable when forging articles of extended
length such as tapering spindles. The gear 47 being so much larger than the feed-
ratchet which is fastened to it that a movement of said ratchet the distance of
the length of a single tooth will revolve said gear sufficient to turn the gears 46,
with which it meshes, far enough to cause the feed-rolls 41 to feed in the longest
blank required.
With my invention any small metal articles--such as steel spheres, conical bullets,
boot-calks, horseshoe-calks, screws, nails, &c.-may be forged cheaper than by any
other method yet known, as the metal-forging mill is continuous and automatic in its
action and capable of great speed.
By using flat curved platen-dies arranged so as to be operated by a continuous
rotary or circular motion I am able to attain the very best results.
I desire to state that I have made use in this specification and its claims of
the term "plate or platen dies" to specifically point out and distinguish them
from "die-rolls already combined with automatic mechanism, and fully described
and claimed by me in the metal-rolling mill patent, No. 12,951, hereinbefore mentioned.
