An Improved Device for Handling Ingots.
I, WILLIAM WILSON HORN of the firm of Horn & Son of 151 Strand in the
County of Middlesex Patent Agent do hereby declare the nature of this invention
(a communication to me from Thomas Brady Foreman of Steel Works, Thomas
Charles Powers Vesselman Albert Julius Maher Real Estate Dealer and Michael
Joseph Quinn Real Estate Dealer all of South Chicago County Cook State of
Illinois U.S.A.) to be as follows:-
:-
This invention relates to devices for handling ingots in the process of manu-
facturing steel, and it has for its object to provide mechanism whereby the ingots
may be handled more conveniently and rapidly than heretofore.
In the manufacture of steel it has been customary to set the moulds in a pit in the
converting mill to receive the molten metal from the ladle. After casting the ingots
they have been stripped of the moulds and loaded upon a special car to be transferred
to the rolling mill. This has been a laborious process and it has been attended
with the disadvantage that the ingots have been exposed to the air before being
charged into the furnaces thereby frequently causing the surface of the ingot to
become cracked.
My invention has for its object to avoid as nearly as possible the manual handling
of the ingots and this I accomplish first by mounting the moulds or flasks upon a
specially constructed car, in which the moulds remain while the molten metal is
being poured into them said car being provided with a pivotted frame in which the
said moulds are mounted; secondly in providing a pushing device by means of
which the ingots may be pushed from the moulds into the furnace said pushing
device being so constructed and arranged as to be capable of serving two or more
furnaces.
My invention relates more particularly to the detail construction of the said car.
and pushing mechanism for adjusting and operating the latter and in such other
details hereinafter described.
The first portion of my invention consists of the following parts:
The base plate, which is mounted upon a foundation of masonry, is provided on
its upper side with longitudinal track-beams. Rack bars are formed upon the outer
sides of the said track-beams.
At the ends of the base plate are mounted vertical standards, the upper ends of
which are connected by the longitudinal track-beams.
A car rides upon the said longitudinal track-beams. Said car consists of a plat-
form mounted upon trucks. The platform has depending arms supporting a plate
that forms a slide fitting between the track-beams. The wheels of the car are
provided with spur wheels that engage the before mentioned rack-bars.
The slide plate serves to prevent lateral displacement of the parts when in
operation.
A mast is mounted pivotally upon the platform of the car. The upper end of
said mast is likewise mounted pivotally in a car or carriage mounted to ride upon
the upper track beams of the frame.
The last mentioned car is provided with wheels that ride upon the track beams
and a similar slide plate to that before mentioned.
The lower car has lugs adapted to be engaged. by a lever or catch pivotally
attached to the mast for the purpose of locking the latter in position for operation.
The mast carries a horizontal pusher-cylinder both ends of which are connected
with the mast near the upper end of the latter by means of guys or braces...
The cylinder has a movable piston & piston rod and to the front end of the

page_text: piston rod a head is attached and this end of the rod is also perforated to receive a
hook at the end of the drawing tongs when the device is to be used for drawing the
ingots from the furnace.
The front end of the cylinder has attached thereto a bracket for the purpose of
relieving the stuffing box of the weight of the piston rod & preventing undue strain
thereon.
The
The upper and lower sides of the cylinder are provided with bearings for a pair
of longitudinally sliding rods which extend through openings in the mast.
front ends of said rods are provided with means for engaging perforated lugs or
staples at the upper ends of the moulds.
The cylinder is manipulated by means of a handled lever.
A table or platform conveniently situated is provided for the operator who attends
to the working of the lever and other parts of the machine.
A clutch for the purpose of drawing the moulds containing the ingots when the
device operated for pushing the ingots out of the moulds, is arranged in a suitable
position and is provided with a handle for its manipulation.
The piston in the before mentioned cylinder is operated by hydraulic power, the
water being supplied under pressure to the ends of the cylinder through pipes
connected with a four-way valve-having a supply and exhaust connected therewith.
The cars carrying the pusher-cylinder and its attachments are carried along the
tracks by the following means :—
A hydraulic cylinder is arranged alongside one of the track-beams upon the base
plate, having a piston and piston rod connected to the latter.
Water under pressure is supplied to either end of the cylinder at the will of the
operator.
The ends of the piston rods have brackets attached thereto each of which is
provided with bearings for two pulleys. Other similar pulleys arc arranged near
each end of the bed frame.
A wire cable is attached at one end to the bearing frame of the pulley at the end
of the piston rod and after passing round the before mentioned pulleys is secured at
the other end to the car in any convenient manner.
A second cable is attached. to the opposite ends respectively of the piston rod and
the car in a similar manner.
It will be understood by the foregoing description that when the piston is moved
in either direction the car is also moved, the movement of the latter being opposite
to that of the piston rod, by the arrangement of the cables and pulleys.
It is also to be understood that the upper & lower cars are moved at precisely the
same rate of speed thereby preventing accidental displacement of the parts. Brake
mechanism may be fitted to the lower car.
The ends of the piston rod are provided with means for relieving the stuffing
boxes of the cylinder of the weight of the piston rod and its attachments.
The foregoing description refers to the ingot pushing and drawing mechanism
which is in practice to be arranged between two furnaces, being capable of serving
either or both of them.
I now proceed to describe the construction of the car carrying the ingot-moulds
in which the ingots are transported from the converting mill to the furnace.
Arranged alongside the bed-plate and parallel to the track-beams thereon, are
tracks extending from the ladle-supporting frame at one end and to the rolling mills
at the other, the said tracks are arranged intermediately between the base-plate and
the furnaces.
The mould-supporting car, composed of longitudinal sills, supported upon wheels
and supporting vertical end frames provided with bearings for trunnion-plates for
the purpose of enabling the mould carrying frame to be manipulated and adjusted
as required, the trunnion-plates are retained in the bearings by means of annular
flange plates suitably secured to the said trunnion-plates.
The mould carrying-frame is composed of two heavy side girders provided on
their inner sides with flanges to support the moulds when the latter are in a

page_text: horizontal position-the said girders are provided with strengthening ribs on their
outer sides, and are cast hollow in order to admit of their being charged with water
for preventing injury from the heat of the ingots. The ends of the girders are
provided with flanges adapted to engage supporting cleats upon the inner sides of
the trunnion plates. The side pieces or girders are firmly secured by means of keys
to the said supporting cleats. The moulds or flasks are in the main of ordinary
construction, but are provided with lateral flanges that extend thro' slots in the side
pieces, which slots admit of a limited movement of the said moulds. The said
moulds are provided at their upper edges with perforated lugs or staples, which are
engaged by the rods hereinbefore described.
The moulds are open at their lower ends and are provided with a moveable
bottom-plate adapted to be disengaged from the mould for the purpose of enabling.
the ingots to be pushed out when required.
Suitable means are provided for supporting the bottom plate of the moulds when
required. The trunnion plates and the mould-carrying frame may be swung, or
tilted, so that the moulds may be inclined to either side into a horizontal position.
The furnaces are arranged as described, and are, in the main, of ordinary
construction, and provided with a suitable number of charging doors-means being
provided for tilting the ingot, which is first charged, to either side of the charging
door, so as to leave room for the next one.

An Improved Device for Handling Ingots.
I WILLIAM WILSON HORN of the firm of Horn and Son 151 Strand in the County
of Middlesex Patent Agent, do hereby declare the nature of this invention, a
communication to me from Thomas Brady (Foreman of Steel Works) Thomas
Charles Powers (Vesselman) Albert Julius Maher (Real Estate Dealer) and
Michael Joseph Quinn (Real Estate Dealer) all of South Chicago, County Cook
in the State of Illinois United States of America, 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 devices for handling ingots in the process of manu-
facturing steel; and it has for its object to provide mechanism whereby the
ingots may be handled more conveniently and rapidly than heretofore. The
invention consists in the improved construction, arrangement and combination of
parts which will be hereinafter fully described, and particularly pointed out in the
claims.
--
Heretofore in the manufacture of steel it has been customary to set the molds
in a pit in the converting-mill to receive the molten metal from the ladle. After
casting the ingots they have been stripped of the molds and loaded upon a special
car to be transferred to the rolling mill. This has been a laborious process and
it has been attended with the disadvantage that the ingots have been exposed
to the air before being charged into the furnaces, thereby frequently causing the
surfaces of the ingots to become cracked. My invention has for its object to
avoid as nearly as possible the manual handling of the ingots, and this I accom-
plish, first by mounting the molds or flasks upon a specially constructed car, in
which the molds remain while the molten metal is being poured into them, said
car being provided with a pivoted frame in which the said molds are mounted ;
secondly, in providing a pushing device by means of which the ingots may be
pushed from the molds into the furnace, said pushing device being so constructed
and arranged as to be capable of serving two or more furnaces. My invention
resides more particularly in the detailed construction of the said car and pushing

page_text: mechanism, in the mechanism for adjusting and operating the latter and in such
other details of construction which will be hereinafter fully described with reference
to the drawings in which

Like numerals of reference indicate like parts in all the figures.
1. designates the base plate which is mounted upon a very substantial foundation-
of masonry and which is provided on its upper side with longitudinal track-
beams 2 2. which may be cast or formed integrally with the base-plate. Rack-
bars 3. are formed upon the outer sides of the said track-beams.
At the ends of the base-plate 1 are mounted the vertical upright plates or
standards 4 4. the upper ends of which are connected by the longitudinal track-
beams 5 5. which as shown in the drawings will be shaped or composed of plates
having upwardly extending flanges at their outer edges. 6 designates a car which
is mounted to ride upon the longitudinal track-beams 2. Said car consists of the
platform 7 which is mounted upon the trucks 8 8.
The platform is provided with downwardly extending arms 9, supporting a
plate 10 that forms a slide fitting between the track-beams 2 2. The wheels 11
of the car 6 are provided with spur-wheels 12, that engage the longitudinal
rack-bars 3, thereby preventing the wheels from dragging or sliding upon the
track-beams. The slide-plate 10 serves to prevent lateral displacement of the parts
in the device when in operation as will be hereinafter described. 13 designates a
mast which is mounted pivotally upon the platform of the car. The upper end of
said mast is likewise mounted pivotally in a car or carriage 14, which is mounted
to ride upon the upper longitudinal track beams of the frame. The car or
carriage 14, is provided with wheels or rollers that ride upon the track-beams and

page_text: it has on the under side a slide-plate 15, that fits between said track-beams and
prevents the car from being laterally displaced. The car or carriage 6 is provided
with a lug 16, having a notch 17, adapted to be engaged by a lever or catch 18
which is pivotally attached to the mast which latter may thus be locked in position
for operation. The car platform is provided with a notched lug at each end, with
either of which the locking lever may be placed in engagement.
The mast 13 carries the horizontally-arranged pusher-cylinder, both ends of:
which are connected with the mast near the upper end of the latter by means of
inclined guys or braces 19.
The cylinder which is designated by 20, has the longitudinally-movable piston
rod 21, which is provided with a suitably located piston 22. The front end of the
piston-rod extends through a packing box 23 at the front end of the cylinder.
24 designates a head which is mounted detachably at the front end of the piston-
rod. Said head which is cylindrical in shape is provided with a longitudinal
perforation 25, by means of which it is mounted slidingly upon the piston-rod and
it has at its rear end a staple or perforated lug 26, through which a key or
pin 27 passes into a perforation in the piston-rod upon which the said head may
thus be locked. The front end of the piston-rod is also provided with a per-
foration 28, to receive the hook at the end of the drawing-tongs when the device is
to be used for drawing the ingots from the furnace as will be hereinafter described.
The front end of the pusher-cylinder is provided with a forwardly extending
U shaped bail or bracket 29, having a perforation 30, for the passage of the
piston rod. The object of this is to support or partially support the weight of
the front end of the piston-rod and to relieve the packing box 23 of such weight
thereby preventing injury to the said packing box and avoiding the leakage which
would otherwise in time result from such strain or wear. The upper
and lower
sides of the cylinder are provided with brackets 31, having bearings for a pair
of longitudinally sliding rods 32. which rods also extend through transverse.
openings 33 in the mast or derrick. Pivotally connected to the front ends of the
sliding rods 32 are the grappling arms 34, the front ends of which are provided
with hooks 35, adapted to engage perforated lugs or staples at the upper ends of
the molds as will be hereinafter described.
Connected pivotally to one end of the cylinder is a lever 36, having a handle 37
by means of which it may be conveniently manipulated. The ends of said lever
are provided with swiveled eyes 38 encircling the grappling arms 34, and serving
when the lever is manipulated to bring the outer or free ends of said grappling
arms together or apart as may be desired. 39. designates a table or platform
which is secured near the lower ends of the mast or derrick at one side of the
pusher-cylinder. This platform is for the accomodation of the operator whose
duty it is to attend to manipulation of the lever handle 37, and other parts of the
pusher-cylinder which are to be hereinafter described. 40 designates a clutch
member which is mounted to slide longitudinally upon the cylinder and which is
provided with perforated lugs or brackets 41, for the passage of the longitudinal
rods 32, which are secured in said brackets. Springs 42, are coiled upon the
rods 32, between the brackets 41, & 31, and serve to force the clutcli member 40,
and the rods 32, normally in a forward direction.
-
A clutch member 43, is arranged revolubly upon the cylinder between the clutch
member 40, and the mast.
The clutch member 43, is provided with a handle 44, by means of which it may
be manipulated to force the clutch member 40, in a rearward direction.
This is for the purpose of drawing the molds containing the ingots up against the
head at the front end of the piston rod when the device is to be operated for
pushing the ingots out of the molds as will be hereinafter described thereby
relieving the mast and other parts of the machine of excessive and unequal strain
which might prove injurious.
The piston-rod in the pusher cylinder is operated by hydraulic power the water
being supplied under pressure to the ends of the cylinder through pipes which are

page_text: designated by 45 & 46. Both of these supply pipes are connected with a valve
casing 47, containing an ordinary four-way valve 48. Suitably connected with said
valve casing are also the supply pipe 49, and the exhaust or discharge pipe 50, the
latter extending through a vertical perforation in the lower end of the mast. The
valve itself forms no part of my present invention it being simply so constructed
that the supply may be connected with either end of the cylinder while the exhaust
is connected with the other end, or that the supply and exhaust may both be cut
off at will. The supply pipe 49, extends from the valve casing up alongside the
mast 13, and through an opening 51, in the side of the latter and thence in an
upward direction through the top of the mast and through the car or carriage 14,
above which the said supply pipe 49, is connected with a swivel jointed pipe 52,
composed of any desired number of sections having their meeting ends connected
by swivel-joints so as to admit of said swivel-jointed pipe being extended or con-
tracted according to the position of the car carrying the pusher-cylinder.
The end of the swivel-jointed pipe 52, is connected with the main supply-pipe 53,
which is mounted adjacent to one of the end plates 4, of the frame. A pair of
longitudinal track-rods 54 having their ends attached to the upper ends of the end
plates 4, of the frame, serve to support the swivel-jointed supply-pipe. The cars
carrying the pusher-cylinder and its attachments are operated or carried along
their respective tracks by means of mechanism as follows. 55, designates a
hydraulic cylinder which is arranged alongside of one of the track beams 2 upon
the base-plate and which is provided with a piston rod 56, extending through
packing-boxes 57, at both ends of the cylinder. The piston rod 56 has a centrally-
focated piston 58. Pipes 59 & 60 for supplying water under pressure are connected
with the ends of the cylinder and with the casing 61 of a four-way valve 62, which
is also connected with the main supply and discharge pipes 63 and 64 in such
a manner that water may be supplied to either end of the cylinder while it is being
discharged from the opposite end or that both the supply and discharge may be
simultaneously cut off. The valve 62 is operated by means of a lever or handle 65.
To the ends of the piston-rod 56 are attached the brackets 66 each of which is
provided with bearings for two pulleys 67 and 68.
Guide pulleys 69 and 70 are suitably arranged near each end of the bed frame.
The frame-plates 4 are provided near their lower ends with perforations 71,
adjacent to which guide pulleys 72, are arranged and similar guide-pulleys 73. are
arranged near the upper of each of said bed-plates 4. To the bearing frame of
each of the guide-pulleys 69 is attached a wire cable 74 which passes over the
pulley 67. at the adjacent end of the piston rod. 56. thence under the guide-
pulley 69, thence over the guide pulley 72-and-through-the-perforation-71_and_to_
the adjacent end of the car or carriage 6, where it is securely attached in any
convenient manner. To the bearing frame of each of the pulleys 70 is attached
a similar wire cable 75 which passes over the guide pulleys 68 at the adjacent
end of the piston rod 56 thence under the guide pulley 70 and over the guide
pulley 13 to the adjacent end of the car or carriage 14 to which it is suitably
attached. It will be seen that by the foregoing arrangement of parts when the
piston rod 56 is caused to move in either direction the cars or carriages 6 & 14
supporting the mast 13. with the pusher cylinder and all its attachments will be
moved, in the opposite direction. It will also be seen that the upper and lower
cars are moved at precisely the same rate of speed thereby preventing the
possibility of any of the parts of the machine getting out of alignment. It may
here be stated that the lower car 6 is to be provided with suitable brake
mechanism 175, the special construction of which however is not considered a part
of my present invention. This brake mechanism is considered desirable for the
purpose of effectually preventing any possibility of the machinery being displaced
while in operation and it will be seen that such brake mechanism serving to lock
the wheels of the car having spur-wheels intermeshing with the rack bars upon the
longitudinal track beams will effectually and positively prevent longitudinal dis-
placement of the car while its lateral displacement is quite as efficiently prevented

page_text: by the arrangement between the longitudinal track-beams of the slide-plate 10
which forms a part of the car structure. The piston-rod 56 is provided near each
end with an upwardly extending yoke or bail 77, which rides upon guide-rods 78
which are suitably attached at the ends of the cylinder to the frame plates 4 at the
ends of the frame structure. By this means the weight of the ends of the piston
rod carrying the pulley-frames 66 is taken off the packing boxes at the end of the
cylinder the advantages of which will be readily understood. The parts of my
invention thus far described and which constitute the mechanism for pushing the
ingots from the molds into the furnaces and for drawing the ingots from the
furnaces may be operated by two attendants one of whom is stationed at the valve
lever 65, controlling the mechanism for causing the cars to travel in either
direction and the other of whom is stationed upon the table or platform 39,
whereby they may conveniently manipulate the lever handle 37 whereby the
grappling-rods 34 are actuated, the lever-handle 44 by means of which the clutch
member 43 is operated and a lever handle 79 which is suitably connected by
means of links and connecting rods with the stem of the valve 48, which latter
may thus be manipulated so as to cause the piston-rod to be operated in either
direction. The ingot pushing and drawing mechanism which has been described
in the foregoing is in practice to be arranged longitudinally between two furnaces
which may be of any suitable construction and dimensions.
I prefer this arrange-
ment for the reason that owing to the fact that the mast or derrick carrying
the pusher cylinder is swiveled in the manner described it may be employed to
serve two furnaces or sets of furnaces as well as one. Consequently a considerable
economy in the initial cost of the plant may be effected by arranging the pushing
and drawing mechanism to serve two furnaces one on each side as described.
I shall now proceed to describe the structure of the car carrying the ingot-molds
in which the ingots are transported from the converting mill and to the furnaces.
I desire in this connection to call attention to the Patent granted to me in the
United States on the 15th day of October 1889 No. 412,832, for improvements in
devices for casting ingots. This device is the one which it is intended to use in
connection with my present invention and it provides for the casting or the
pouring of the molten metal from the ladle directly into the molds which are
described as being supported upon suitable cars. The special structure of said
cars however I purposely omitted to show or describe in the Letters Patent above
referred for the reason that the said car structure is more properly a part of the
present invention. I make the foregoing statement merely to show that I have
provided means whereby the ingots may be cast in molds supported upon a
travelling car structure. Arranged or constructed alongside the bed plate 1 and
parallel to the track beams 2 on said bed plate are the tracks 80 which extend at
one end to the frames upon which the ladles are supported while casting ingots and
at the other end to the rolling-mills. The said tracks 80 are arranged inter-
mediately between the base plate 1 and the furnaces which latter are designated
by 81. The mold supporting car is composed of the longitudinal frame pieces or
sills 82 supported upon the wheels 83 and supporting the heavy vertical end
frames 84. The latter are provided with bearings 85 of large diameter for the
trunnion-plates 86 between which and the bearings the friction rollers 87 are inter-
posed for the purpose of enabling the mold carrying frame to be conveniently
manipulated and adjusted to its proper position. The trunnion plates and the
antifriction rollers are retained in the bearings by means of the annular flange
plates 88 which are suitably secured to the outer and inner sides of the trunnion
plates.
The mold carrying frame is composed of two heavy side pieces or girders 89
which are provided on their inner sides with flanges 90 to support the molds when
the latter are in a horizontal position and on their outer sides with longitudinal
strengthening ribs 91 and 92 formed respectively at their upper and lower edges
and longitudinally along the centre.
The side pieces: or girders 89 are cast hollow in order to admit of their being

page_text: filled or charged with water for the purpose of preventing the heat from the ingots
from warping or otherwise injuring them. The ends of the girders are provided
with flanges 93 adapted to engage supporting-cleats 94 upon the inner sides of the
trunnion plates. The side pieces or girders are secured firmly in the said sup-
porting cleats by means of keys 95, driven into the said cleats alongside of the
Hanges 93. The inner sides of the side pieces or girders are provided with vertical
supporting cleats 96 to receive flanges 97 formed at the ends of transverse brace-
plates 98 by means of which the said side pieces or girders are securely connected.
It will be observed that by this construction and arrangement the parts constituting
the mold-carrying frame may be very conveniently and securely put together or
taken apart for repairs while at the same time great strength and firmness of the
various component parts are attained which is obviously important owing to the
heavy weight which has to be sustained and the circumstances under which
the ingots are to be handled.
;
The molds or flasks which are designated by 99, are in the main of ordinary
construction but are provided with laterally extending supporting plates or
flanges 100, that extend through the vertical slots or port holes 101, which are
formed in the side pieces or girders 89 directly above the central strengthening
ribs 92 of the latter. The slots 101, it will be seen will admit of a limited
movement of the molds or flasks 99 in the direction of the length of the latter.
Said molds or flasks are provided at their upper edges with perforated lugs or
staples 102 adapted to be engaged by the grappling rods 34 of the pushing
mechanism which has been herein before described.
In the drawings hereto annexed I have shown the mold carrying frame as
supporting a series of four molds but it is obvious that a greater or less number
of molds may be used when desired. The molds are open at their lower ends, and
the bottoms for the said molds consist of a series of blocks 103 mounted upon or
formed integrally with a plate 101, which is provided with an annular upwardly-
extending flange 105 surrounding the individual mold bottoms. The bottom
plate 101 provided on its upper side near its-ends- with perforated -lugs, or
staples 106 by means of which said, bottom plate may be suspended under the
molds in such a manner as to be capable of being disengaged from the latter for the
purpose of enabling the ingots to be pushed out after the molds have been adjusted
to an approximately horizontal position.
The trunnion plates 86 at the ends of the car are provided with radial slots 107
in which are mounted the supporting devices for the bottom plate of the molds.
Each of said supporting devices comprises a shaft 108, extending through the
slot 107 and having at its inner end a downwardly-extending arm 109 provided at.
its lower end with a hook 110. The outer end of each of the shafts 108 is provided
with an arm 111.
Connected pivotally to the outer side of each of the trunnion plates 86 at a
point near the upper end of the slot 107 is an arm or lever 112 having an
eccentric ring 113 through which the outer end of the shaft 108, having the
arm 111 extends
The eccentric rings 113 are provided near the fulcra of the levers 112 with
notches 114. It will be seen that by manipulating the said levers the shafts 108
may be raised or lifted upwardly in the slots 107, thereby lifting the mold-bottom
which has been previously mounted by its lugs or staples 106 upon the hooks 110
up into contact with the lower ends of the molds.
The mold bottom may be retained in this position by placing the ends of the
operating levers 112 under studs 115 attached to the trunnion plates.
It will be seen that the mechanism for adjusting the mold bottom is wholly
connected with the trunnion plates.
Hence the latter may be turned so as to adjust the molds to any desired
position without changing the position of the mold bottom, which is important for
reasons which will be hereinafter made apparent.
The trunnion plate 86 at one end of the car is provided with a bracket 116, to

page_text: which is attached a segmental gear or rack 117 which is concentric with the upper
half of the trunnion plate.
Brackets 118, secured to the upper end of the end plate 84, are provided with
bearings for a shaft 119, provided with a worm 120 engaging the segmental
rack 117. The shaft 119 has a square end 121, upon which a crank 122 may be
placed for the purpose of manipulating said shaft. It will be seen that by this
mechanism the trunnion plates and the mold carrying frame may be swung or tilted
in. an arc of one hundred and eighty degrees, thus enabling the molds to be tilted to
either side into a horizontal position.
It is obvious that the parts of the mold carrying car and the pushing mechanism
are to be so proportioned with relation to each other that the molds when
occupying a horizontal position shall be practically in horizontal alignment with
the piston rod of the pusher cylinder.
The furnaces 81 are arranged, as above described, alongside of the tracks 80
and parallel to and at a suitable distance from the frames of the ingot pushing and
drawing mechanism. The said furnaces are in the main of ordinary construction―
a suitable number of charging-doors 123 which are located a suitable distance
apart, so as to enable two ingots to be charged through each one of the doors
means being provided as will be presently described, for tilting the ingot, which is
first charged to either side of the charging door, so as to leave room for the next
one. For the purpose of thus tilting the ingots out of alignment with the charging
doors, I avail myself of the peels 124, each of which consists of a plate of suitable
dimensions having slightly upturned or curved side edges 125, and provided at its
front end with a downwardly extending arm 126. The front. of the furnace is
provided, with bearings for a longitudinally sliding dump-bar 127, which is provided
in its front edge with a series of notches 128 to register with the charging
doors 123. One end of the dump bar is connected by means of the pivoted
rod 129 with one arm 130 of a bell crank lever which is fulcrumed at 131 and the
other arm 132, of which serves as a handle by means of which it may be
manipulated to impart a longitudinally-sliding movement to the dump-bar 127.
When the ingots are pushed or charged into the furnace as will be hereinafter
described, the peels 124 are first placed in position it being unnecessary however to
slide the said peels into the furnace until the arms or handles 126 engage the
notches of the dump-bar. When the ingots are afterward pushed into the furnace
they will carry the peels with them until the handles 126 of said peels engage the
notches 128 in the dump-bar. It will thus be seen that. by manipulating the bell-
-crank lever in such a manner as to slide the dump-bar in either direction the peel
will be tilted, thus rolling or tilting the ingots supported thereon to either side of
the charging doors of the furnace. In the practical operation of my invention the
car carrying the ingot molds filled with the molten metal is transported upon the
trucks 80 from the converting mill, and to the furnace. The car is so arranged as
to bring the molds or flasks, into alignment with the charging doors of the furnace
and the cars 6 and 14 carrying the mast 13 and the pusher-cylinder with its
attachments are then manipulated to bring the said pusher cylinder into alignment
with one of the molds and furnace doors.
The adjustment of the pushing mechanism may be very quickly and easily
effected by means of the operating mechanism actuated by the hydraulic
cylinder 55. The mold carrying frame of the car is then tilted by means of the
worin and segmental rack to bring the molds, into a horizontal position with their
upper ends towards the, pusher cylinder.
While the mold-carrying frame is being tilted to bring the molds in a horizontal
position the bottom plate of the molds is suffered to remain in contact with the
lower ends of the latter, which are thereby closed, this being obviously necessary
for the purpose of preventing the ingots from dropping out of the molds by
gravity. When the mold carrying frame has been sufficiently tilted to bring the
molds into a horizontal position or nearly so, the eccentric rings 113 are operated
by their levers, or handles 112 which are released from under the studs 115 to
-B

page_text: -
permit the shafts 108, having the supporting hooks 110, to move outwardly in the
slots 107, thereby releasing the bottom plate from the lower ends of the molds and
permitting the said bottom plate to swing down between the ends of the car-frame.
The lever man or operator who is stationed upon the platform 39 now manipulates
the pivoted grappling arms 34 by means of the lever 36 and handle 37 to cause
the hooks 35 at the front or outer ends of said grappling-arms to engage the lugs
or staples 102 at the upper ends of the hobs or flasks 99. This having been done
he next operates the clutch member 43, by means of the lever or handle 44 to force
the clutch member 40 and the rods 33 to the front ends of which the grappling-
rods are journaled in a rearward direction against the tension of the springs 42
thus drawing the mold containing the ingot up into contact with the head 24 at
the front end of the piston rod 20 in the pusher cylinder and serving to hold
the said mold securely while the ingot is being pushed out. The sliding movement
of the mold just described is made possible by the presence of the vertical slots or
port holes 101 in the mold carrying frame in which the said molds are supported
by their flanges 100.
The lever-man now manipulates the operating rod or handle 79 of the valve 48
to so adjust said valve as to cause water under pressure to be admitted through the
pipe 46 into the rear end of cylinder thus causing the piston-rod to move in a
forward direction and to push the ingot out of the mold and into the furnace
through the charging-door with which it is in alignment. By reversing the
valve 48 the piston is next caused to recede and by manipulating the valve
controlling the supply of water into the cylinder 58, the carriages supporting
the pushing mechanism may now be adjusted to place the piston into
alignment with the next mold after which the operation may be repeated. When
all the ingots have been pushed into the furnace the mold-carrying frame is
restored to its normal position and conveyed back into the converting-mill to
receive a new charge while the pushing mechanism is held ready to operate upon
the next car-load of ingots that may arrive-from the converting-mill. After all
the furnace doors have received their first charges the dump-bar 127 is manipulated
to tilt the ingots into the spaces between the charging-doors of the furnace and the
peels may then be withdrawn, leaving the furnaces in readiness, to receive the
second charge. After having served the furnace on one side of the pushing
mechanism the pushing-cylinder is reversed and made to serve the furnace on the
opposite side.
When the ingots have remained in the furnace for a sufficient length of time to
raise them to the desired degree of heat they may be drawn by using drawing-
tongs of ordinary construction provided with hooks to engage the perforation 28 in
the front end of the piston-rod.
The head 24 of the piston-rod is meanwhile slid in a rearward direction upon the
nd so as to expose the said perforation 28, this being done by simply releasing
e key 27 from engagement with the recess or opening in the piston-rod.
By the use of the grappling tongs the ingots are drawn out upon a suitably
constructed car which inasmuch as it forms no part of my present invention has
not been illustrated in the drawings and upon which they may be conveyed along
the tracks 80 to the rolling-mill. The advantages of my invention will be readily
understood from the foregoing description taken in connection with the drawings
hereto annexed by those skilled in the art to which it appertains. By the ordinary
method of manipulating ingots it has been customary to strip the ingots from the
molds in the converting-mill, where the molds are set for casting in a pit under the
pouring-ladle.
The process of stripping the ingots has necessarily been slow and laborious
requiring the assistance of numerous operators the services of many of whom may
be dispensed with by my invention.
In addition to this the steel is kept in a far better condition than heretofore
owing to the fact that it is at no time between the casting of the ingots and the
charging of the ingots into the furnace exposed to the drafts of cold air which

page_text: have heretofore been instrumental in cracking and injuring the surfaces of the
ingots, frequently entailing considerable loss owing to the inferior quality of the
product. Another important advantage certain to be derived from my invention is
the facility with which the ingots may be handled in a highly heated state, thereby.
effecting a considerable saving in the fuel necessary to raise them to the necessary
degree of heat for rolling. Other advantages might be mentioned but it is thought
that the foregoing will be sufficient to illustrate the superiority of my improved
devices for handling ingots over the methods ordinarily employed. In the detailed
construction of the various parts of my invention I have aimed not only at so
constructing the various parts of the mechanism as to facilitate the actual handling.
of the ingots but I have had specially in mind the difficulties to be overcome
owing to the heavy weights to be handled and the highly heated condition of the
ingots. It is obvious that all of the structural parts of the device must be so
constructed as to gain the greatest possible strength and to avoid the possibility of
breakage while at the same time simplicity of construction is important not only
for the purpose of reducing the initial expense of the plant but also to facilitate
the assembling and putting together of the parts many of which are necessarily
heavy and cumbersome. I believe that I have attained these objects by the
construction and arrangement of parts herein described, and illustrated in the
drawings hereto annexed; but 1 desire to have it distinctly understood that T
reserve the right to any changes and modifications which may be resorted to
without departing from the spirit of my invention. I also desire it to be under-
stood that while for various reasons I consider hydraulic pressure to be preferable
as a motive and actuating power in connection with my invention I reserve the
right to use any other fluid pressure.
