Integral with the 'body portion 51 are two pairs of spaced upstanding perforated ears 6 I'Y-in the perforations ot which are Vreceived the trunnion pins 54, from which the ladle 56 is supported.
'.Theladle 56, T-shapedmembers 49 and pins 54.7 are preferably made of some suitable high temperature `Y`resisting ceramic or otherV material which will noti be deleteriouslyl affected by repeated immersions in the supply of molten metal contained in the melting'furnace.
VItjgis: thought that vthe operation of this machine will-be clearly understood from the foregoing. butfbrieiiy stated itis as follows, reference beinghad particularly to Figs. 1 and 4.
`The arms-48am adiusted tothe correct lengths to properly position the ladle 56 with respect to the sprue`62 of the injection cylinder63. At the beginning of the cycle of operations-the gear rack 23 is substantially in the position shown in Fig. l latz'the lowermost position of its stroke. The onerator'admits hydraulic fluid into the conduit 28 connected tdcylinder I6 which causes the piston rod`2| toVA travel upwardly and correspondingly to move lthe gear rack 23 which is guided in its travel by roller 28 in cam groove 21. This movementfoi the gear rack 23 causes simultaneous rotation of the gear 38 and cam wheels 32 and 33 thereby. effecting pivotal movement of the arms 42 and 43 about the shaft 4l.
"'Initheseouence of operations in each cycle the cam wheels 32 and 33 first-move the arms 42 and 43 in parallel relationship, to the position shown iny broken lines in Fig. 1 at which position the ladle: 56 while horizontally1 disposed' is immersed in the pot of the melting furnace 64 and is substantially'illed with molten metal; In the next stagethe ladle 56 is elevated above the surface level of the molten metal and is then caused to be vtipped or inclined a predetermined extent so thatlip 5S is lowered and a predetermined quantitybf molten metal is caused to be drained back int th'e meltingv furnace 64 leaving a desired quantity of molten metal in the ladle 56. It will b understood that adjustments may be made in members 48 to vary the 'degree of inclination and correspondingly to vary the quantity of molten metalretained in the ladle 56.
rn lthe next stage of the cycie the ladle `5t may be caused to resume a horizontally level position as above explained. At this point the rack 23 will have reached a position so that the cam roller 28 is substantially at the point where the cam groove 21 begins to incline from the vertical, as seen in Fig. 6. It will be apparent that continued upward movement of the cam roller 28 in the cam groove 21 will cause the gear rack 23 to rotate about its axis andcorrespondingly will cause the cam housing i4 to rotate about the axis of the cylindrical housing H. The arms 42 and 43 are thus caused to swing the ladle 56 effecting a traverse of the ladle to a position for c pouring the molten metal into the sprue 62 of the injection cylinder 63. In the next stage of the cycle the cam wheels 32 and 33 act to elevate the arm 43 above arm 42 which may be lowered to effect an inclination of the ladle 55 to the position shown in the broken lines in Fig. 4 whereby the molten metal is caused to be discharged into the sprue 62. At this point the piston rod 2l will have reached the limit of its upward travel and the operator then eiects a reversal in the direction of the travel of the piston rod by admitting hydraulic fluid into conduit'i. It will be apparent that in the downward movement of the gear rack 23 the direction of rotation of cam wheels 32 and 33 is reversed and the sequence of movement of the ladle 56 is correspondingly reversed.
The cycle of operations hereinabove described may be controlled by an operator who initiates the forward and reverse movements of the hydraulic cylinder i9 as by the operation of a control valve. It will be understood however that means such as limit switches and solenoid valves may be utilized in connection with the structure herein described to effect continuously automatic operation of the apparatus, it of course being necessary to synchronize the movements of the ladle 56 with the operation of the injection piston of the die casting machine.
It-.is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and
that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the appended claims.
