CASTING-SEPARATIN G MACHINE.

To dll-'whom t mayconoern:

,Be itv known that I, MoNTFoRn B. MURRAY, a citizen of the United States, residing at Albion, vcounty of Calhoun, State of Michigan, haveinvented a certain new and useful Improvement in Casting- Separating Machines, and declare the following to be a full, clear, 'and exact description of the' same, such as will enable others skilled in theart to which it pertains to make and use the same, reference being had to the accompanying drawings, which forma part of this specification.

This invention vrelates to machines for separatlng castings, and its object is a machine adapted to take a stack of annealing.

pots containing the castings and packing and separate the castings and packing. A further object of the invention is a selfepro'- pelled machine adapted topick up stacks of pots in sequence from a row and separate the castings and' packing as stated' and discharging the empty pots, packing, and castings separately. Other objects of the invention reside in thepmeans taking the stack of pots and shaking the contents from the individual pots of the stack in sequence. Further features of theinvention are involved in the means for shaking the pots and in delivering the castings separately from the packing. These and other objects and the several novel features of the invention in its preferred form are hereinafter more fully described and claimed and shown in the accompanying drawings in which- Figure l is a side elevation of a machine embodying my invention.

Fig. 2 is a plan view thereof. Fig. 3 is a front elevation of the device for picking up the stack and transferring the pots to the shaker device. F Fig. 4 is a section taken on line -W of Fig. 5 is an enlarged detail showing the device for picking up the stack of pots and mechanism employed in elevating the stack to position for delivering the pots to the shaker. r y

movement thereof.

Fig. 9 is a plan view of the driving mech? anism employed for operating the machine.

Fig. 10 is a detail of a portion of the driving apparatus.

The machine consists preferably of. the metal framework indicated aft l and having upper `and lower horizontal members connected by vertical members 2 forming a substantially rectangular-box like skeleton frame. At the forward end of this framework is carried a structure 3 carrying the fixed vertica-'l memibers 4 which in turn support what I have termed the transfer' and unloading device 5 indicated more clearly in Figs. 3, 4 yan-d 5. Attached to the inner side of the vertical members 4 is a member 6 having a channel 7 therein providing a guideway at each side for rollers 8 on the ends of the horizontal shaft 9. This shaft i is carried at the lower end of the vertical members l0 forming the unloader frameworkv as indicated clearly in Fig. 3. AA

sha-ft 11 is also provided at the upper end of these frames and both the

shafts

9 and 11 have a pair of sp-rocket wheels thereon as indicated clearly in Fig. 4. On each upper and lower sprocket wheels runs a .chain 12, the chains being connected by a series of bars 13 which may be attached thereto in any approved manner as 'by the U shaped brackets 14. The shaft 11 on opposi-te ends is provided with a Smooth faced friction wheel 15 whereby the shafts and chains may -be operated as hereinafter described. Extending across the lower end of the unloader and preferably supported beneath the pots for member 16 on which the stacks of pots rest when the unloader is in vertical'position as shown in Fig. 1, the pots being indicated thereon in dotted lines.

The frame of the machine on the inside and on opposite side members thereof is provided with a grooved track member 17, each ytrack member receiving'a roller 18 on each side member 10 of the unloader frame as indicated clearly in Fig. 3. The rollers are each supportedbn a stub sha-ft. 19 carried by a bracket 20 connected with the frame members 10. As before stated the rollers 8 ride in the vertica'l channels 7 mounted on the unloader frame and the rollers-18 ride in the grooved channel 17 the shaft 9 is a table 1 attached to the framework. Therefore, by vertical movement of the unloader frame the said frame may be lbrought upward from the -position shown at the left hand end of Fig. 1, the upper end of the framework drawing to the right by reason of the rollers 18 riding in the channels 17, as the' vertical frame is moved.- upward until it assumes the horizontal position as indicated by dotted lines in Figs. 1 and' 5. In this position the friction wheels 15 are brought into engagement with similar wheels 21 on the shafts 22 operated in a manner hereinafter stated. Therefore, when the unloader device has been brought to the posiv tion shownby dotted lines in Fig. 1, by

reason of the weight of the device and load.

carried, the wheels 15 are made to friction ally engage the driving wheels 21 and thus the shaftI 11 and the chain members 12 are rota-ted. This movement moves the pots toward the right as indicated by 'dotted 'lines in Fig. 1 to lthe shaker device hereinafter described.

The unloader device 1s moved upward in the manner described by means of a 4cable 23. This cable may be attached to the frame `member as indicated at 24 in Fig. 1, passes thence upward about a -pulley 25, thence downward about a pulley 26 loosely mounted thereon so that rotation of the From the pulley 26, the cable extends upward about the pulley 27 and thence downward to the winding drum 28 on the shaft 29 eX- tending crosswise of the machine near the forward end. Thisshaft 29 lis driven by means of a motor 30. in geared relation with a gear on a shaft .31 extending crosswise from the machine which is in turn geared to the shaft 29 by means of a gear mesh,

ing with the gear 32. It is to be noted that, there. is a cable 23 onopposite sides of the machine as indicated more clearly in Fig. 1, and thus on rotation of the shaft 29 the unloader frame is raisedl with the lower end thereof driven in the vertical channels 7 and the upper end turned to brin the unloader to horizontal plane yas previously stated, whereupon the chains 12 Y are operated and the box is delivered to vthe unloader.Y When the Ipots have been discharged as stated, the overh-anging weight of the unloader is suiiicient to return i-t to vertical position on release of the winding drums and cables 23.

It is to be understood thatin a foundry for instance, where a great many castings are made, the pots are usually stacked in rows after the castings have been poured and this machine is brought to the rows and the first stack is placed thereon and machine operated to deliver the pots to the shaking device after the manner described and then the machine is moved forward and the second stack of the row lis pickedl up and emptied and the operation repeated for all the stacks.

The shaking device to which the pots are delivered from the transfer and unloader device is indicated in Figs. 1, 2, 6, 7 and 8. In Figs. 1 and 2 it will b e observed that a Vchain 33 is provided on opposite sidesv of the positioned members 34 on the two chains 33 1. `These clralns run about' a as seen in Fig.

sprocket wheel at the forward end on the shaft 37 in the inside of the framework and,

on opposite sides thereof as will'be understood from -Fig. 2. These chains extend from the sprocket 37 to the rear end of the machine about a sprocket 38 on the shaft 39 supported at the upper side of the framework at the end and thence about a sprocket on the shaft 40, which shaft is adjustablv mounted in the bracket 41 carried at the lower side of the framework at the end. By thisv arrangement for adjusting the shaft the chains may be tightened to take up slack. These chains are driven by the shaft V37 which shaft is driven by means of a chain 43 running on'vthe sprocket 42 of the shaft 37 and sprocket L14of the drive shaft 45 extending -across the lower side of the framework. The shaft 45 is driven by means of an electrical motor 46 which drives a chain 47 connected with a sprocket wheel 48 on the shaft 45. This driving mechanism is shown in detail in Fig. 9 and by driving the shaft 37 as indicated, the chains 33 are made to move in the direction of the arrow shown in Fig. 1. As also indicated in said figure, the annealing pots with the castings and packing therein are discharged from the transfer table in the manner hereinafter described to fall onto the rollers 36 carried by the chains 33 open side downward so that the castings and packing are both discharged therefrom to fall between the rollers, those being Iall that extends across the machine at the point mentioned from the shaft 37 to the rear end of the machine as will be understood from Fig. 2. lThe castings and packing in fallingy through lthe rollers, fall onto4 a series of longitudinally extending bars 49 lying at an 'angle to the horizontal as is shown in Fig. 1. At the lower end these bars 49 rest loosely on the shaft or bar 50 ektendin'g transversely of the machine and at the upper forward end are connected With the shaft 37 in a manner indicated in Fig. 2. This shaft is provided with a series of eccentrics, the eccentric bands 51 extending thereab'outl each being connected with a bar 49, and by arrangement of the eccentric' and connection of the bars there- With the bars during rotation of the shaft are given a reciprocatory motion. The bars are spaced apartl transversely of the machine as indicated and the motion o-f the bars continues to shake the material from the castings and tween the bars, and the castings, by reason of the motion of the bars, being finally discharged at the lower end onto the inclined table 52 down which fthe castings roll into suitable collecting device that maybe positioned to receve the same. The packing simply drops through the bars and onto the floor and the pots are discharged at t'he rear end of the machine riding off from the rollers 36 in the manner indicated with the pot a-t the end of the machine shown in Fig. 1.

In order to insure the pots being discharged of their contents, a sawtooth track 53 is provided on each sideof the4 upper part of the framework of the machine preferably just inside the chain member 33 and, by movement -of the chains v abou-t the sprockets, the rollers are moved vertically in the slots provided in the members 34 and the pots are shaken vertically to discharge the contents.

To further insure thev proper driving of the chains 33 the shaft 37 on lthe end opposite that shown in Fig. l is provided with a sprocket on which runs a chain 90 driving a sprocket 91 on the shaft 39 at the rear end of the machine.

The driving mechanism for ope-rating the shaker is shown clearly in Fig. 9 Where it may be seen rthat the chain 47 drives the shaft 45 on the outer end of which is the gear 44 for driving the chain 43 and the shaft 37. As will be l 9, a clutch device 55 is mounted on the shaft 45 which, as shown in Fig. 10, extends through the pot 56 on the frame member of the machine and through gear 44. The gear and hub are rotatable on the shaft and are connected to the outer drum of the clutch 55, the inner clutch member of which is indicated at 58 and the operating collar at 59. The member 58 is keyed to the shaft 45 and, by sliding'of the collar 59, the member 58 is, through operation of shown),

the dogs 60, made to frictionally engage the member 55 by `which connection the gear 44 is made to turn with the'shaft 45. There is an operating lever for this clutch (not here operable from the operators stand 6l shown by dotted lines in Fig. 2. By they the shaker chains may be operated at will. n.

Carried on the frame at the rear of the shaft- 45 is a transverse shaft 62 having

the hub 57 of the' shaft 62, and

sprockets

63 and 64, the machine may be lpropelled to any desired positi'on on the floor, it beingxunderstood that the forward wheels 68 are steering wheels guided, for instance, by means of a steering wheel 69 at the operators Stand. The shaft 62 is provided with a gear 70 driving ya differential gear set in the casing 71 connected respectively with two parts of tl'ieshaft 62 as will be readily understood. The gear 72 on the shaft 45 meshes with the gear 70 and drives the lsame and the gear 2 is connected with a case or drum 73 of a clutch similar in construction to that of the clutch l55, the shell 73 and gear being loosely mounted on the shaft and adapted to be clutched thereto by operation of the sliding member 74. Thus at will the machine may be propelled over the floor by setting of the clutch members 74, and the clutches independently or simultaneously driven as determined by the operatorby setting the clutches. As we stated heretofore, the friction wheels *15 of the transfer and unloading` device are operated by reason of con- These wheels plainly in Fig. 2, being on carried in lbearings provided in brackets 75 on each side respectively, of the machine. On the outer end of the shafts for the friction wheels 2l are sprockets operated by a chain 76 which chain runs over an idler sprocket 77 in the opposite end of the bracket.. rFhe chain 76 intermediate the shaft for the friction wheels 2l and the idler 77 runs -over a sprocket 78 'on the shaft 37 by means of which the chain is driven, as will be understood from Fig. l. V

From the foregoing description `it bccomes evident that while the machine is large and substantial in character it is comparatively simple and economical in operation, particularly in that annealingpots in quantity may be emptied of their contents and for this purpose it is preferable that the stacks of pots 'be slightly elevated above the floor in order to allow the foot or receiver member 50 of the transfer and unloading device to be insertedthereunder by movement of the vehicle. Thereupon the winding drums 28 are set into operation windingupV the cables23 and raising the transfer and unloading devices 'in a manner hereinafter stated to the horizontal position with the rollers l5 in contact with the driving rolls 2l and operating the chains l2 and the conveyer. The conveyer moves the pots in sequence backward and face downward onto the shaker device, which,` by reason of the vertical movement of the rollers on which the pots are deposited, shakes the material v outof the pots and onto the grating formed of the bars 49. The castings are delivered 2l are shown independent shafts,

` to. the inclined table 52 at the rear of the a table adapted to be introducedbeneath a device upon which they may be allowed to bdeposit on the iioor or into any suitable receptacle properly positioned therefor.
