Application filed November '6, 1922. Serial Nc. 599,191.
To all whom it may concern;
- Be it known that we, 'ELMER O. BEA Ds- Lay-and \VALTER Fnlmcis PIPER, both citi- Zens. of the United States, and residents of Chicago, in the county' of Cookand State of Illinois, have invented certain new'and useful Improvements in Molding Machines, ofwhich the followingis a-full, clear, and
. The invention relates to molding machines. V
r In making niolds by high speed sand pro- I jectors, the flasks are usually. overfilledto insure the complete-fillingthereof and the excess is stricken oif by a'bar. This excess is considerable in volume,
V V particularly where the flasks are rapidly filled, v as is a the case when rotary high speedsandpro jector s are used. -One 'objeet of the" invention is to' provide means for feeding the strike-off sand back to the molding ma-' chine. r
, Another objectoi? the .inv"ention is to provide improved, means for dellvermg flasks toand from the sand proj e'ctors to facilitate the work of the machine and toincre'ase its output. 5
Other objects of the invention will ap- *pear from the detailed description;
, The invention consists heseyeral novel features hereinafter set forth and more par- 'ticularly' defined by claims at tlie conclusion *he'reof.'""

V Thesandprojector or' rnolding machine I illustrated is substantiallyl'o f the c onstruction eichibited in Patent Nog 1,408,493, dated. "March. ,7, 1922, and comprises a supporting standard fixed'on. the" truck, a; jib tipiyi oted to the standard so. as to swing. hor-.-- izontally, errant- 15. piyo't'ed to theouteriend of thei jib, 3 a sand? projector :46 containing a rotor driven by an electric motor 47 which is. mounted to.- swing I horizontally with the M11145, aivibratory .conveyor-chuterg con-- taining a riddle 4:8,and mounted to] swing withnj'ib heltfiflmoul ited to swing with said arm and for feeding sand: from chute 48' to the projectonjandfa case-49, containing mechanism forl-yibratingitlie chuteAS and ineluding'an electric moton, all of. which may be of the conjst ru'etion set forthin said patent, to which reference inz y-be had for a more detailed descriptipn thereof. Stand aid-35 is-disposed; at one sidefot the.truckflasks adjacent tlieqcenter of the truck.
"Standard 351is' clamped toi'pipe 13 by U- bolts 3? andjholted {to-a bracket-36 which" is secured to'a standard 60. This mechanism exemplifies a sand projector which is mounted on the truck and is movablelaterally. so as todischarge sand into'all portions'of flasks below the projectonj The sand is supplied to the projector from a pile on the floor ahead offthetruck by a jcross-conveyor consisting offa screw 54 on a cross-shaft55 An inclined trough-plate 58 in the rear of the conveyor-screw cooperateswvith' the latter :to' direct sand to one,
side of the machine. Plate 58 issecured'to lower rear sprocket165.
ricd bya shaftr63 which is, held in staud ard 60,-the lower end of which is secured to frame-side 10; Sprocket 64 is carried by a andjsupportcdfrom frame-pipe 13 by U-bolt clamps '57. Conveyor-screw 54 and platebS terminate inwardly of frame 'side10'and a sand elevator 15 disposed betweenone end of the conveyor and. said frame-side; 'This'ele-f vator comprises an endles's chain'm59 and buckets 61 proj-ectingfrom'one' side of the chain. Chain 59 passes around a. drivesprocket 62which is fixed to :shaft and elevated idler sprockets 63 and 64 and a shaft 66 which'is carried by a leve'r67. Said lever is pivoted to a standard fiO and.i s 0p erated by va tension device; 67 to cause sprocket 64 to keep the elevator chain taut.
Standard. is secured to frame-side'- 10 by U-bolts '68 andtostandard 60' by a bracket- 69. The-reach of th-e elevatorbetween sprockets 63 and 64; extends over the; inner; end of conveyor-chute 48, so that theelevator. buckets will discharge the sand directly into. the chute. ,Tlns construction exemplities mechanism for conveying sand from a pile in front of the truck to on-esidethereof and elevatingit for projectoron the truck.-
I An electric motor 70, is secured'on framedeliveryto' the side 10 of the truck frame and drives the:
sand'conveyor and elevator jand tlie; propelling mechanism for the truck .i Shaft-z55 of conveyor 54 is driven from said motor-bye pinion 71 on the motor shaft, a gear72. meshing 'with, pinion/Z1 and mounted onzastud 73 carried by fframc-side 10,- t 'pllllOIL74 which. is rigid with g'ear, 72 and a ,gear 7 5 meshing with pinionv 7 1 andfixcd to one end of na'ft 55; The elevator is driven by sprocket 62 which is fixed 'tof'shaft '55. r The traction-wheels are {driven to propel the truck to cause it to progressively advance into the sand pile, by an eccentric pin76;on'
one end of shaft, 55', a pawl 78pivoted-toand operatedby 'saidpin a ratchet-wheel 79 engaged by said pawl. and a pinionSO which is,
rigid with said ratchet. and rotateson a stud .81 on frame-side. 11. Pinion-SO has teeth conforming to the. teeth on the traction wheels 21 and engages one of them. the other being driven through cross-shaft 26. A dog" 8:? prevents rctractionbf ratchet 79.
- A desideratum in the operation Ofllllgll Sprocket (33 is ca1:-.
cured tothe lower endo't A bevelled gear 102 is fixed which 105*on a shaft 106.'
speed sand projectors is to deliver the flasks into-and out of the position in which they are filled by the projector with facility-to increasethe work of the machine; For this purpose,- a rotatable carrier D is provided. A series of flask-supports 84 are supported "on this carrier to bring flasks in rotativc suc cession into position to be filled-and. so that a flask may be placed on the support for dc-i livery to the projector and a filled flask may be removed from its support while another ffl'ask is being filled. This rotatable carrier'is formed of a disk of boiler plate 85 which is fsecured toa socket or housing 86. Housing 1 86 is sustained so it is horizontally rotatable by "roller-bearings87 which are carried by a hollow standard 88 which is secured by bolts 89 to the cross-bar 16.01 the truck frame. A roller 90 onan axle 91 insaid standard is adapted to ride on a central rail 92 to render the standard, which supports the carrier,
vertically rigidL .'l he'marginal portion of is carried b a'hearin 101 with the r-1nggear97vto I] no from sprocket 65 which is driven by the elevator chain 59; A'sprocket .103fixed to r'o tate with sprocket '65 drives .a chain 10stv passes around and drives a sprocket Said "shaft 1s supported i-n-a bearing 107 formed in frame-side 10 and-drives-a bevelled gear 108 which meshes 'with bevelled gear 102. This gearing exemplifies mechanism .for continuously rotating the flaskecarrier. Being continuously driven, this CaIfIJGI WIIl deliver the flasks placed 011 the supports 84 to the space beneath. the convenient range of thesand proje'ctor i'n rotati've s uccessionand also carry 'themaWay, As aresult, while, one flask is beingfilled by the projecto1", ouc or more cmpty'flasks can-be placed on the supports rotating towards the projector. At the same time, an operator may strike off the flask which has been previously filled and can a move that flask. This construction excurplifies driving, mechanism for the carrier which delivers, the flasks to-and from the projector.
'The carrier,d'isk 85 also receives the c.'\'- ress sand which .is stricken from the filled flask and the spill fronrthe projector. The. operator usually strikes the. sanzl from the flask as soon as it has passed to the right handQside of the machine and before removing the flask from its support 84. The
- strike-oil sand-falls on disk 85 so that it 'will rotate therewith. In 1 its rotation 1 with the disk the sand; will engage stationary guidestrips 110-, 11-1.

".As each flaskreachesza point adjacent and beneath the projecto the operator will shift the project p into the flasks and fill them. As the flasks are moving rearwardly and after-they. have been filled, {an operator strikes off the sand which 't' ftil'l be deposited "on the carrier disk. and "their" removes completed" molds from the carrier sfo'that the supports may receive:
