Application filed June 21, 1913. Serial No. 775,005:

To all whom it may concern Be it known that I, CLARENCE L. BROW'ER, a citizen of the United-States, residing at Chrome, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in ldosh- Cranes, of which the following is a specification.

Among the objects of this invention is to provide an eilicient de 'ce for conveying the anodes from the mold or conveyor to the boshes, ,and for providing means of adpistment between the grappling device and the up the anode and where it will deposit the same.

The various features of novelty and advantage will be brought out more particularly in describing the invention in connection with the drawings and diagrams ac companying this specification, In the drawings, one practicable embod ment of the invention is illustrated, in which drawings-v E Figure l is a plan view of various portions of the plant showing the invention in connection therewith. In this view there is illustrated the furnace, the conveyer, the crane, and a plurality of boshes. a cross-section of the parts illustrated in Fig. 1 taken at about the plane of the line 2-2 in Fig. 1. Fig. 3 is an end elevation of a ortion of the trolley, and a cross-section of the trolley bridge, and shows a broken away portion of an anode carried by the crane; Fig. i is a side elevation of the trolley and the crane carried thereby; and Fig.

5 is a top plan view of the trolley.

In one method of refining copper, the copper is run in a molten condition from some suitable furnace-a furnace is illustrated herein at 10-into molds for molding the anodes. The molds are illustrated in a continuous rotary conveyer. There is shown a wheel 11 having a series of molds 12 carried thereby into which the molten copper is run and is formed into anodes 13. This conveyor is shown located between the furnace 10 and a lurality of boshesin which the'anodes will be quenched before being conveyed to the electrolytic bath.

The boshes are represented at 14,- 15 and 16; the bosh 15 is shown at one side of the conveyor substantially diametrically opposite the discharge spout 17 of the furnace.

The conveyor will be rotated step by step,

' the anode.

Fig. 2 is each of the molds 12 will have a sufiicient quantity of metal run into it, and the conveyer will then he stepped around to bring the next mold in position. When thein'old e ed anodes arrive in the region of the bosh into which they are to be placed, they wi ll be removed from their molds and cen'veyed to and deposited in the bosh Each of the molds is provided with some suitable means for clearing the cast anode. In the present instance a pin 18 passes upwardly throu h the bottom of the mold, and

has an end epending below the mold in position to'be engaged by a cam surface. 19 adjacent the position where the anode will be removed from the mold. The pin will be caused to rise and thus lift the end of The outer end of the anode is shown provided with a pair of engaging lugs 20.

It is found difiicult in practice to always have the molds from which the anodes are to be taken brought to a given working point at the time the crane is ready to act. The crane must be able to do its work at various positions along the path of revolution of the molds. For this reason in engaging the anode, moving it and depositing it in position, a certain amount of flexibility of movement must be provided in the engaging device, and owing to the location and arrangementof the parts the engaging device must move positively to its position to engage the anode, and must become positively positioned before depositing the same in the quenching bath. The invention therefore provides a crane having a grapping device or pick-u with aswivel motion allowing rapid adJuStment to be made to ac: commodate the difference in position be:

tween the mold and the bosh that it is desired to cover. As shown in the drawing, the boshes are placed side by side, whic naturally will bring them indifferent positions along the path of revolution of the mold. The boshes are provided with racks in the ompa n ashes This present e other reason tor providing the flexibility of movement of the grapple or pickup.

In the illustration there is shown a bridge 22 havin wheels 23 running upon tracks 24.

The bridge is provided with rails 25 for receiving the wheels 26 of the trolley 27.

' -Suitable' means will be provided for causing versely of the other, so that it may be moved by the resultantof a compound movement Themechanism for engaging the anodes will move transversely of the plane of this compound movement, and will also have a swiveling motion in a plane parallel with such plane of movement.

There is shown mounted upon the trolley a rigid leg, that is rigid in that it is held with the trolley for movement in its two movements, and will be practically free from vibration or swinging independently of the carrier or trolley. This leg in the present illustration comprises a tubular shaft 30 which is caused to rotate by means of a feather 31 engaging a guide 32 (presently to be described), and throughwhich guide it is caused to travel. The traverse of the member 30 is effected 'by a cable 33 connected to the head 34. .The cable runs over a pair of drums 35 provided with cable grooves 36. The grooves are shown right and left handc'd so that the head 34: will not be moved from side to side as the cable is wound and unwound. The head 3 is shown as having a swivel connectio riewith the shaft 30 and is guided in its traverse and held from rotation with the shaft 30 by means of a iair of guide rods 37 passing through gui es 38. The guide rods 37 are movable vertically with the shaft 30. Each end of the head is shown provided with a sheave 39 over which the cable 33 passes for permitting the cable to automatically adjust itself should there be more stretch upon one'side than upon the other. A too free movement of the cable however is prevented by suitable clamps 40, or frictiondevices. The rigid leg 30 is controlled in its vertical traverse and supported by a cable and an outrigger .con-

' struction. v

The grappling device 41 is shown nonrOtatably carried by the shaft 30 and rotaa motor 46 mounted upon the trolley. various motors for actuating the varmus parts ot the apparatus will have their con trolling devices conveniently located for th e manipulation of "the operator while or the 7 platform 29.

tions 121 122 and 123 in which osilions .I. l w l V the anodes are lirted by the pins 18. h roni either of their positions the crane may carry the anodes to either of the boshes 142, 15 or 16. T9 do this the bridge 22 will be moved upon the tracks 24- to a [H'iSlilOl'l in. line with the anode to be lifted, and the trolley will be .moved' over the anode into such a position that by a swivelirg the head 41 (if necessary) and a rl wnward traverse of the head and shaft 30, Lne hooks 42 will come into position to engl'agr the lugs 20 which have been raised from the mold by means-0f pin 18 and cam 19. The head will then be raised to clear the anode 13 from its mold. The trolley'will then be given the proper movement by means of its traverse of the bridge, and the bridge of its tracks, to bring the center of the shaft 30 into line with the longitudinal center of the bosh.

During this movement the head ll will be caused to rotate by means of the worm gearing above referred to, and when the anode 13 has been brought to its proper position relatively to a pair of the notches 2L shaft 30 and connected mechanism will be caused to lower by means of the playing out of the cable 33, and the anode no; asited in the bosh. When the anodes are taken the from the position indicated at 122, no swiv cling of thehcad will be required; but when taken from positions 1.21 and 123 the heal will be swiveled in opposite directions to bring the hooks into proper engagement with the ears on the anode castings. it may sometimes arise that some diiiiculty will be experienced in conveying or depositing an anode where desired, and that the revolution. of the molds will have brought the anode past its usual point of being taken up, in which case the operator will be able to readily move the grapple into its proper posi tion for engaging the anode and for conveying it and depositing it where desired. The extensible part of the crane is thus seen to be rigid and to be positively moved from one position to another and positively held in such position and the swivclii mo tion of the engaging portion of this tensible member is also positively moved and positively held in position.

It will be apparent that the form of the device herein shown and described is illustrative of the invention, and that changes may be made Within the scope of the claims without departing from the-spirit of the invention, for the purpose of adapting the im vention to the exigencies of its use, and that it may be used in other situations than that described, the present showing being one of its many uses.
