This invention relates to a machine for casting metal into pigs, bars or other shapes and for dumping the castings from the mold to a. conveyor or system of conveyors which carries the castings to a stacking machine or to any other receiving means. The 1nvention relates further to a casting machlne having a set of stationary molds arranged 1n a series and mounted for movement from a normal casting position intoa dumping position and having means movable relatively to said series of molds for carrying molten metal thereto for casting and for receiving castings from the molds and for carrying Said castings away therefrom. -V Various other objects and advantages of the invention will be obvious from the following particular description of one form of mechanism embodying the invention or from an inspection of the accompanying drawings which illustrate certain new and novel features of construction and combinations of parts hereinafter set forth and claimed.
In the drawings accompanying and forming part of this specification, a practical commercial embodiment of the invention is disclosed, but as such illustration is primarily for purposes of disclosure, it will be understood that thestructure may be moditied in various respects without departure from the broad spirit and scope of the invention as hereinafter v:defined and claimed.
Fig. 1 is a plan view in part cut-away showing a series of tiltablefmolds arranged along an arc of a circle, means for feeding molten metal to said molds which means is movable along the series of molds, and means comprising a circular` conveyor and an un loading apparatus for 'receiving castings dumped from said molds and `vfor carrying them away;
Fig. 2 is a plan viewy of part of the circular conveyor of Fig. 1 showing additional parts of the unloading and recelvlng apparatus and means for driving the circular conveyor and for driving a receiving apparatus.
Fig. 3 is a sectional view taken along the line 3-3 of Fig. 1; .l
Fig. 4 is a diagrammatic'showing of a series of molds illustrating ,the tipping mechanism;
Fig. 5 is a transverse-'sectional `view of4 one of the molds showing by dotted lines the position of supporting and tilting bosses and journals thereon; and
Fig. 6 is a longitudinal sectional view of the mold of Fig. 5.
In the drawings the circular channel shaped member 1 comprising thel base member 2 and the upright members 3 and 4 supports the bearing rings 6 and 7 which carry between them a series of horizontally disposed molds 10 which extend about the circle formed by said supporting member 1, a gap being left through a short are where apparatus hereinafter fully described occupies space required for unloading. At the center of the circle of the support member l is mounted a vertical pipe 12 for carrying molten lead which pipe connects through the universal joint 14 to the feed pipe 15 which empties into the casting bowl 18, said casting bowl being mounted near the outer edge of the platform 20.
Said platform may be in the form of a sector of a circle which is supported at its inner end about said universal joint 14 and at its outer end on the track which is mounted on an inward extension of said base 2 and over which track roll the wheels 26, 27 mounted to said platform 20. Rotation of said platform 20 about its center and over track 25 is secured'by means of the motor 30 which is mounted to table 20 and which is geared through shaft 28 to said wheel 27.
Said casting bowl 18 is supported on platform 20 by means of the bearings 32, 32,
ywhereby the bowl 18 may be tipped as b means of handle 33 for pouring molten lea or other metal, from bowl 18 into several of the molds 410 through the pouring spouts 36, 36 provided on the front side of bowl 18 and spaced apart thereon at such distances that .metal may be poured to several of said molds simultaneously.
Each of said molds 10 is pivoted at each of its ends to said bearing rings or members 6 and 7 by means of the journals 40 and 41 respectively to permit the molds to be turned from a normal casting position into an inverted dumping position, a stop member 42 being provided at each endl for engagement with said bearing rings 6 and 7 to hold the molds horizontal either in the normal position or in the inverted position. The journal 41 carries at its outer end the tilting shoe 45 for engagement with the tilting members 46 and 48 mounted to and movable with said platform 20 (see Figs. l and 4). In the normal casting position said tilting shoe 45 hangs downwardlyfrom journal 4l and in the inverted position the shoe 45 extends upwardly above journal 41. With the molds 10 in the normal casting position and upon rotation of platform 20 and members 46 and 48 in a clockwise direction said member 46 is engageable to contact with shoes 45, 45 to tilt the molds from the normal position into the inverted position and upon further advancement of the platform 20 and members 46 and 48, the member 48 -will contact with the shoes 45, 45 which have been inverted by member 46 to return the molds successively into the normal position all as indicated by the diagram shown in Fig. 4 and as hereinafter more fully described. Members 46 and 48 are mounted at a distance apart equal to a small multiple of the distance between consecutive molds and with member 46 before member 48 in the direction of their movement and bothl before the pouring bowll8 whereby metal poured into a mold may be permitted to solidify before it is dumped from the mold by theI tilting of the mold into the inverted position by contact of said member 46 with said shoe 45.
On the base member 2 underneath the series of molds 10 and between the supporting members 3 and '4 there is mounted the circular track 50 over which rides the wheels 52 mounted to and underneath the circular table 54. The table 54 is completely circular and provided with a plurality of the wheels 52, 52 and is thereby self supporting. To the outer edge of table 54 and underneath it is mounted the circular driving rack 56 which serves through the motor 57 and the transmission apparatus 58 to drive said table 54 over said track 50. The table 54 is of such a width and of such a distance below the molds lO, 1() as to suitably accommodate and receive castings when they are dumpedfrom said molds 10, 10. The table or conveyor 54 may be driven at a rate of speed different from that of the casting arrangement ]8-36 to suit the method and manner of removing the castings therefrom. From the above description it can be seen that a casting after being poured is permitted to set duringl the time required to make nearly a complete revolution of the castingvarrangement over the molds,
Over said table 54 and extending diago-4 nally thereacross is supported a series of vertical idler rollers 60 which are suitably mounted for rotationon 'their vertical axis.
These rollers 60 extend into such proximity to said table 54 as to contact with castings lying thereon and are adapted to wipe said castings outwardly from the table as they are carried by the table againstA the rollers, the diagonal mounting of said rollers across table 54 being outwardly with respect to the rotation of said table 54. These rollers 60 are mounted ybelow the blank space in the series of molds 10, l0 as above noted. Extending from the outer end of said series of rollers 60 is the conveyor belt 62Which is driven by the motor 63 and which is designed to receive castings as they are discharged from table 54 and to carry them to the stacking machine 65 which is indicated diagrammatically and which is mounted at the discharge end of said conveyor 62. ln the line. of movement ot' castings from table 50 and paralleling said rollers 60 there extends a row of horizontal idler rollers 66 from the outer edge of table 54 to the receiving end of said conveyorI 62. These rollers 66 are preferably inclined from table 54 to conveyor 62 and terminate above the level of said conveyor 62 whereby castings pushed olfl table 54 by idler roller 60 slide over rollers 66 and drop therefrom onto said conveyor 62. As shown in Fig. 2 said conveyor 62 comprises a multiplicity of endless chains 68 driven by said motor 63 to the shaft 69 and the chain 70.
In the operation of the apparatus illustrated in the drawing molten metal is fed through said pipe l2 and tln'ough universal joint 14 to the pipe 15 and discharged into bowl 18. Bowl 18 may then be rotated-with table 20 as by means of motor 36 to bring the pouring spouts 36, over all the molds 1t), 10 and the bowl tilted on its bearings 32, 32 as by means of a handle 323, 33 to pour 1 the metal from bowl 18 into several of the molds 10, 1U. lhe pouring arrangement is then rotated in a clockwise direction to bring said pouring spouts 36, 36 over the next corresponding set of molds and the pouring operation is repeated. As the pouring arrangement is rotated the member 46 successively engages the tilting shoes 45 and successively inverts the molds 10, 1l) and the member 48 as it comes adjacent the inverted molds in turn contacts with said shoes 45 in the inverted position and returns the molds successively into the normal casting position. After about a complete revolution of the pouring apparatusl and upon contact of said member 46 with the successive shoes 45, 45, castings poured into the molds 10, 10 are dumped from their respective molds onto said table 54. Each mold after having received the inverting impetus is carried to loo i lllf) the complete inverted position through the VThe member 48 which is spaced at a short distance from member' 46 reverts the molds successively to their normal positions a short time after they have been dumped.
lThe castings which have been dumped from the molds 10 and Awhich have been received by the conveyor table 54 are carried by that table, against said idler rollers 6() which wipe them from the table and discharge them over the horizontal idler roller 66 and onto the conveyor 62 which discharges them to a suita le position as for example into a position to be operated upon by the stacking machine which is diagrammatically shown.
The metal may be fed continuously through pipes 14 and 15 to the bowl 18 or it may be fed thereto at intervals to keep a suiiicient amount for pouring in saidy bowl 18.- A skimmer may be positioned on said table 20 near bowl 18 for keeping the metal in proper condition for pouring. The table 20 also provides space for an operator forl the motor 30 and the bowl 18. The conveyor table 54 may be rotated at the same rate of speed as the table 2() 'or it may be rotated at some other speed, and for example, it may be rotated at intervals to discharge the castings in sets of predetermined numbers according to the capacity and operation of the stacking machine 65. y
It is to be understood that the cooling ot the `cast metal may be hastened by the employment of jets of' air or by suitable water sprays, Whose use is well known, so that the metal is suiiiciently solidified in the mold beforel it is dumped.
While I have shown and described and 1have pointed out in the annexed claims certain novel features of the invention, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
