4 Claims.

This invention relates to new and useful improvements in multiple pouring devices for ingot molds, and it is among the objects thereof to provide apparatus for simultaneously pouring regulable multiple streams of molten metal to a plurality of ingot molds.

Another object of the invention is the provision of a multiple pouring device which shall be movable with reference to rows of ingot molds into i two or more of which the molten metal is poured simultaneously, and which shall be provided with manual controls for regulating the volume of the flow streams to the several molds into which the metal is simultaneously poured.

5 Still another object of the invention is to provide multiple pouring devices with mechanically operated tilting and tipping mechanism for controlling multiple fiow streams and in which the flow control mechanism is adapted to provide speedy and positive adjustments of the volume of the several flow streams.

A further object of the invention is the provision of means whereby the multiple pouring de-- vice is adapted to the pouring of large or small 5 ingots in molds having different center distances.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawings constituting a part hereof in which like reference characters designate like parts and in which:

Fig. 1 is a side elevational view partially in section of a multiple pouring device embodying the principles of this invention;

Fig. 2 a front elevational view thereof;

Fig. 3 a plan View of one-half of the device shown in Figs. 1 and 2;

Fig. 4 a side elevation partially in section of a modified form of pouring device;

Fig. 5 a plan view of the structure shown in 0 Fig. 4:;

Fig. 6 a. view diagrammatically illustrating the relation of the pouring receptacle and flow troughs;

Fig. 7 a front elevation diagrammatically il- 5 lustrating the pouring receptacle, flow troughs and ingot molds;

Fig. 8 a side elevation partially in section of a form of multiple pouring device whereby four ingots may be poured simultaneously;

Fig. 9 a front elevational view partially in section of a modified form of the pouring receptacle shown in Fig. 8 with flow troughs and ingot molds; and Fig. 10 a plan view of the apparatus shown in Fig. 9.

55 With reference to Figs, 1 to 3 inclusive of the drawings, the structure therein illustrated consists of a concrete base I provided with a pit for receiving ingot molds 2, the pit having shoulders 3. The base I is provided with tracks 4 upon which a steel frame, constructed of channels and. plates 5 is mounted on wheels 6 that ride on the rails to render the sub-structure of the pouring device movable. A cross-frame l is supported on the wheel frames 5 and a ball-joint 8 is mounted in the cross-frame I. A pair of longitudinally spaced flow troughs 9 are rigidly mounted on the frame, a feeding orifice i0 being provided at the bottom of the flow troughs. There are two troughs 8 to which metal is supplied through the orifice ll of a single pouring ladle E2, the view of Fig. 3 being a plan view of onehalf of the pouring device. The ladle I2 is provided with brackets i3, Fig. 3, having spherical seats that rest upon dumbbell-shaped bearings M, Fig. 1, one end of which is supported on levers l5, which are pivoted at l6, Fig. 3, and connected to cranks i1. 5

The front end of the ladle i2 is provided with a spherical shaped bearing bracket l8 that rests upon the spherical ball-joint 8. Levers I5 are connected to the cranks I! by a link l9 and the cranks H are connected by shafts through reduction gears 2i and a worm and worm gear 22 are driven by a motor 23. the gear being housed in a metal box which may be referred to and designated as a transmission 24.

Motor 23 is controlled by a switch or lever 25 and the wheel axles 6 are driven by a motor 26 controlled by a lever 21, the traversing motor 26 being provided with a brake 26a that is operated by a foot pedal 21a.

A plurality of contact brushes 28 are mounted on cross-arm support 29, attached to the frame structure to make contact with rails 30, supplying current for the motors 23 and 26.

Referring to Fig. 1, metal issupplied to the pouring ladle 12 from a ladle 3| which receives the molten metal from a melting furnace, ladle 3| being provided with a pouring orifice 32 having the usual stopper for controlling the flow.

As shown in Fig. 2, the parts, with the exception of the traversing motor and its controls, are duplicated, there being two flow openings II and Ila for the pouring ladle [2 into stationary flow spouts 9 and 9a.

The operation of the apparatus shown in Figs. 1 to 3 inclusive is briefly as follows: with the pouring ladle I! in its normal position, as shown in cross-section, in Fig. 1 of the drawings, it rests upon the front central ball-joint 8 and the two horizontally spaced dumbbell-joints II. One of the dumbbellsjoints II is permanently fixed in the end of lever I5 and the other fits into a socket in lever I51: and into the bracket I3 to provide for misalignment in moving the ladle. The metal is caused to flow from the main ladle 3| through the spout 32 into the pouring ladle I2 with the ingot molds 2 lined up below the stationary flow spouts 9 and 9a. The operator manipulates control levers 25 and 25a which energize the motors 23, which, in turn, actuate cranks I1 and I1a which, through links I9, pull the bell crank levers I5 forward. Movement of levers I5 raise the pouring receptacle I2, causing it to tilt about its front central ball-joint 8 and molten metal will flow from the openings II and Ma. The flow from the openings I I and I Ia is regulated by tipping the pouring receptacle I2 about its central ball-joint 8 and joints I4, this being accomplished by the controls 25 and 25a to raise the lever I5 or I5a as the case may be. In Fig. 3, which is a half plan view of the device, the line :c:r denotes one of the tipping axes, while the tilting axis occurs at a longitudinal line through the center of the ball-joint 8, such line being at right angles to the center line, shown in the drawings as running through the ball-joint 8.

By means of the controls 25 and 25a, the pouring receptacle I2, is in the first instance, tilted to raise the rear portion thereof to regulate the volume of flow to the stationary spouts 9 and by further manipulation of the individual controls 25 and 25a, the receptacle may be tipped to obtain independent regulation of the flow through each of the flow openings II and Na of the pouring receptacle.

By means of the hereinabove described apparatus, a plurality of ingot molds can be poured simultaneously with positive control of the flow stream from the pouring receptacle. The pouring receptacle I2 is of such capacity that the pouring of the metal from the ladle 3| may progress at a rate independently of the rate the metal is poured into the ingot molds, since the control of the flow from the pouring receptacle I2 to the ingot molds through the flow spouts 9 may be regulated independently of the flow from the supply This continuous pouring eliminates the necessity for stopping-oil. the flow from the main ladle which sometimes causes freezing or sticking of the stopper plug, and at the same time the independent regulation of flow to the ingot molds permits slow pouring of the metal to the molds which is advantageous in that it eliminates splashing in the mold and is productive of uniformly dense and sound ingots. The pouring to multiple molds simultaneously permits slowing of the pouring to any desired degree which allows control or regulation of the individual streams. When a pair of ingot molds have been fully teemed, the controllers 25 and 25a are manipulated to reverse the motors 23 and 23a. which causes the pouring receptacle I2 to tilt back to the position where the level of the molten metal is below the flow openings II and Na, thus shutting off the flow. The traversing motor 26 is then energized and the entire receptacle moves on tracks 4 to position where the stationary flow spouts 9 will be centered above an empty pair of ingot molds, and the pouring operation is then repeated.

The apparatus shown and described in connection with Figs. 1 to 3 of the drawings is especially adapted for use in pouring small ingots such as alloy steel, but for use' in the multiple pouring of ingots with larger centers such as seven ft. ingots for sheet metal fabrication, it would necessitate lowering one end of the pouring receptacle an excessive amount in the tipping operations, and for this reason, the form of multiple pouring apparatus shown in Figs. 4 to 7 inclusive of the drawings, is preferred. This structure is slightly modified, although inherently it embodies the same principles of pouring controls described in connection with Figs. 1 to 3 of the drawings.

The structure of Figs. 4 to 'I inclusive is as follows: The numeral l0I designates the ladle by which the molten metal is supplied to the pouring device; I02 the pouring receptacle which, instead of having a central front bearing support, is provided with longitudinally spaced bearings I03 and I03a at the front bottom portion of the receptacle, these bearings being mounted on levers I04 which are pivoted to a cross-frame I05 at I06. The pouring receptacle I02 is open at the top so that in either its normal upright or tilted position the opening will be in alignment with the discharge opening IOIa of the ladle, thus permitting continuous pouring from the ladle when the multiple pouring device is in use. The pouring receptacle I02 is supported at its rear portion by roller I01 that is mounted on a bell-crank I08 which is supported on a bearing I09. One end of the bellcrank I08 is connected by a link I I0 to a crank I I I that is rotated through a transmission I I2 driven by motor H3. Levers I04 are connected by links IIS and Se to levers IIS and IIBa mounted on a rock shaft II1 which is provided with a lever II8 that is connected by a link I I9 to the transmission I20. Upon rotation of the rock shaft H1 in one direction, link II5 will be pulled downwardly to tip one end of the pouring receptacle I02 and in the reverse direction of movement of the rock shaft, link II5a will be drawn downwardly to tip the receptacle in the opposite direction. The tipping mechanism is actuated through a transmission I20 driven by motor I2I, while the tilting operation is by the transmission H2 and motor II3 as previously explained.

The rear roller support I01 for the tilting receptacle is mounted on a bracket I01a which is carried by shaft I09 that in turn is actuated by the bell-crank I08. The pouring receptacle is mounted on a frame structure that is supported by wheeled axles I22 on rails I23 of the substructure. Ingot molds I24 are supported on wheeled trucks I25 placed beneath the receptacle which is adapted to traverse the row of ingot molds for the pouring operations.

A stationary flow spout I26 is provided beneath the flow passages I21 and I21a of the pouring receptacle I 02. Reference numerals yy and y'y', Fig. 5, designate the tipping axes of the pouring receptacle. Numeral I21 designates the controller and numeral I2I the tipping motor, I28 the controller for the traversing motor, not shown; and I29 the controller for the tilting motor H3.

The space designated by the numeral I30 is for the main ladle stopper operator. The operation of the structure shown in Figs. 4 to '7 inclusive of the drawings is briefly as follows:

With the pouring ladle in the position shown in Fig. 4 and a plurality of ingot molds lined up beneath the stationary spouts I26 and I26a, the tilting motor H3 is energized by the controller I29 which, through operating mechanism II2, III, IIO, I09, I08 and MM, causes roller support I01 to raise the rear portion of the pouring receptacle I02, thereby tilting it on the fulcrum supports I03 and I03a. When it is desirable or necessary to tip the receptacle I02, about either axes w or y'y, the controller I21 is manipulated to energize the tipping motor l2l in either direction of rotation, depending upon which axes, yy or y'y', the tilting receptacle is thereby tipped around.

In this manner, the metal flowing from the passages I21 and I210. of the pouring receptacle can be separately controlled to regulate the flow of the metal to the ingot molds. When the molds are filled, the tilting device is operated to lower the pouring receptacle by shutting on the flow irom passages I21 and l2'la to theflow spouts I26 and l28a. The pouring receptacle is then moved by manipulating controller I28 of the traversing motor to bring the flow spouts to center with an empty pair of ingot molds.

Fig. 6 of the drawings illustrates the use of the device when pouring large ingots and Fig. 7 for small ingots, the spacing of the ingots being such that a pair can be aligned with the flow spouts by centering the latter with the ingot molds.

The invention may also be employed to control the flow of metal for quadruple pouring by providing a plurality of openings in the flow spouts which are rendered movable to tip them as shown in Fig. 9 of the drawings. Apparatus for this purpose, with reference to Figs. 8 to 10 inclusive of the drawings, consists of a supply ladle having an opening 202 above a pouring receptacle 203 which, as in the structure of Fig. 4, is provided with a pair of ball supports 204 and 20% longitudinally spaced at the front of the receptacle and a supporting roller 205 at the rear of the receptacle, the roller for tilting and the movable ball-joints for tipping being operative through the same mechanism described in con nection with Fig. 4.

The tilting roller 205 is mounted on an arm 206 carried by shaft 201 that is rocked by a lever 208 operated by a crank 209 of a transmission 2i0 that is driven by a motor 2H. The front ball supports 204 and 204a are mounted on levers 2I2, operated by cranks 2I3, carried by a rock shaft 2M which is operated by a crank 2i5 of a transmission 2 l6 driven by a motor 2, the latter being designated the tipping motor. Links 2 I Be have slotted openings 2l8 which engage pins 2l9 of the rock arm, and in one direction of rotation of rock shaft 2, the lever 2i2 will be actuated in the opposite direction of movement and the rock shaft lever 2i2a will be actuated to raise or lower the ball-seat 204 or 204a, respectively, thus tipping the pouring receptacle 203 in I the manner desired to control the flow of the metal from the passage 220 or 220a to a pair of movable now spouts 22! and 22 la, each of which is provided with a pair of flow passages, the spouts 22! having passages 223 and 223a.

The flow spouts 22l are suspended by links 224, supported on levers 225. pivoted at 226, having link connections 22'! with a rock arm 228, mounted on rock shaft 229, having a crank 230 connected by link 23l to a crank 232 of a trans.- mission 233 driven by motor 234, there being a separate actuating mechanism for each of the movable flow spouts as shown in Fig. 10 of the drawings. The numeral 235 designates the trough tipping controller; numeral 236 the ladle tipping controller; 231 the ladle tilting controller; 238 the trough tipping controller; and 239 the controller for the traversing motor, not shown. The numeral 240 designates the ingot mold supported on wheel trucks 2.

The operation of the above described mechanism is briefly as follows: Metal is poured from ladle 20l to the pouring receptacle 203, and the latter is tilted by manipulation of controller 231, which energizes motor 2 and raises the rear supporting roller 205, through the transmission 2) and connecting linkage. The pouring receptacle is then tipped to regulate the flow through passages 220 and 220a by manipulating the controller 236 to energize motor 2 to actuate levers 2I2 and 2l2a, through the transmission 2"; and the rock shaft 2, the tipping being around the axes 11y and y'y', this being the same control and operating mechanism as shown in Fig. 4, excepting that the levers are connected to the rear of the apparatus. As the metal flows to the movable troughs 22l, the volume of flow from the separate flow streams 222 and 222a. of trough 221, and 223 and 223a oi trough 22in. can be regulated by the trough tipping controllers 235 and 238 which energize motors 234a and 234, respectively, which, through transmission 233a and 233, operate links 23 la and 23 I, through which levers 225a and 225 are actuated. As the levers are moved, the troughs are tilted as shown in Fig. 9, the illustrations being greatly exaggerated for this purpose.

By this manner of control, the flow of metal from the pouring receptacle 2l3 through the pair of flow passages to the troughs can be regulated as desired, and the multiple streams flowing .from each of the tilting troughs can be regulated as desired to simultaneously pour the metal into four ingot molds.

When the trough is perfectly level, it is supported on four supporting trunnions, which consist of brackets with a round end. ()nto these round bracket ends a socket on the trough rests. When the trough is tipped, it is supported by levers 225 or 225a with the opposite ends of the trough supported by the brackets and trunnions. This gives the trough a three-point suspension, rigid enough so that it will not turn over, which would happen if it was supported on the levers 225 and 225a only.

It will be apparent from the foregoing description of the invention that multiple pouring apparatus constructed and operated in accordance therewith provides positive means for obtaining regulable multiple streams of molten metal for charging or pouring a plurality of ingot molds simultaneously. It is also apparent that the apparatus is of rugged, compact and relatively simple mechanical construction in which the operating parts are subjected to minimum wear.

Although several embodiments of the invention have been herein illustrated and described, it will be apparent to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.
