To all 'whom t may concern:

Be it known that I, Anci-nin A.. LANDON, a citizen of the United States, residing at the city oi' Buffalo, Erie county, in the State of New York, have invented certain new and useful Improvements in Casti1ig-Machines,

oi' which the tollowing is a itull, clear, and

exact specification.

My invention relates to improvements in casting machines,and the same has for its object more particularly to provide a ma chine by means of which casting operations may be performedfin a substantially continuous manner.

Further said invention has for its object to provide a machine whereby great economy in floor space may be eiiected, and at the saine time the handling of the materials, in preparation for casting as well as the completed castings, may be greatly facilitated and expedited.

Further said invention has for its object to provide a machine comprising a rcvoluble carrier supported in vertical position and provided with means for receiving a series of molds at one point, and for removing the same therefromat a point adjacent to, but below the point where the same are received hy said carrier.

Further said invention has for its object to provide a machine which may be operated upon from diferent horizontal levels or floors whereby greatly to economize floor space in a manner not heretofore Ypossible where casting Aoperations are performed upon one level or iioor. i j i j Further said invention-has for its object to provide a machine comprisng a revoluble carrier having a plurality of mold supports pivotally arranged thereon, adapted to be brought successively into position for loading and unloading. j

Further said invention has for its object to provide a machine in which the molds are placed upon the mold supports on said revoluble carrier and poured at an upper level, and then are caused to descend by gravity to a lower level where said molds may he removed from said supports.

` To the attainment of the aforesaid ob#l jects and ends my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims.

In the acompanying drawings, forming part oit this speciiication, wherein like nu inerals of reference indicate like parts# Figures 1 and 2 jointly constitute a side view, partiy in section, showing one form of machine constructed according to and embodying my said invention;

Fig. 8 is a longitudinal sectional View of .said mold or flask, and

Fig. 9 is a detail section taken on the line 9-9 of Fig. 4.

In. the accompanying drawings, I have shown my invention as embodied in a inachine extending through` two Hoors of a building. and in said drawings 10 designates the ground or lower floor, and 11 the upper ,iiooix 12, 12 denote a pair of pedestals made of masonry or other suitable material arranged side by side upon the ground floor .10, and at the upper ends of said pedestals 12,-12 are provided hearings 13, 13 in which is supported a shaft 11i. v15 denotes a carrier which isrevolubly supported upon the shaft 14; mounted upon the upper ends of the pedestals 12,12. j

Said revoluble carrier consists cfa rim 15a, hub 15b and spokes 15c connecting said hub with said rim. The ontersuifaceof the carrier rim 15a is provided with gear teeth 16 extending entirely around the same. 17, 17 denote a series of arms or shafts which are mounted upon the carrier 15 at vregular intervals and have their opposite ends extendinar equally outwardly from said carrier 15. Upon said arms or shafts 17, 17 are pivotally supported U-shaped brackets 0i' hangers 18, 18 which are provided at their lower free ends with platforms 19L to 1,91,

in the upper floor 11 of the building, and is V sha'ft36 and secured to one end of a rod 39 - pedestals 12, 12 is a pedestal 2O upon which are arranged, bearings 21, 21 in which is 'supported a driving shaft 22. Upon said driving shaft 22 is fixed a small pinion 23 'meshing with a gear wheel 24 fixed upon the sh'aft25 supported in bearings arranged below the shaft 22, and upon said shaft 25 is further fixed a pinion 26 which meshes with a large gear'wheel 27 fixed upon a shaft 28 supported in bearings 29, 29 arranged at the right hand end of the pedestal 20 and to the right of the shaft 25. The gear wheel 27 meshes with the gear teeth 16 provided upon the outer periphery of the carrier rim 15a.

At the rear end of the driving shaft 22 (see Fig. 1) is fixed a pulley 30 which is surrounded by a brake band 31. At one side of the pulley 30 is supported a bearing .32 in which is pivotally mounted an arm 33 having one end pivotallyv secured to one end of said brake band 31, and its other end ASecured to a rod 34. To the lower end of saidarm' 33 is secured one end of a spring 3'4a which has its other end secured to the pedestal 29. The said spring 34a serves to hold the brake band 31 normally in engagement with the periphery of the pulley 30. The other end of said brake band 31 is secured tothe shaft upon which the arm 33 is mounted. The upper end of the rod 34 extends through a suitable opening provided connected to one end ofan arm 35 whose other end is fixed to a shaft 36 supported in bearings 37 arranged upon the upper floor 11.= 38 denotes an arm depending from the whose other end is secured to a depending arm 40a fixed upon a shaft 41 supported in bearings 42, secured upon the upper floor 11, and 41a denotes an operating lever also fixed upon said shaft 41.

o Upon the lower floor 1 0, and arranged at both `sides of the carrier 15 is provided a platform 43 which is supported above the floor. 1Q' upon uprights or standards 44, 44. Upon, each of saidplatforms is supported a table 44a provided with an opening 45a bevlow which is arranged a hopper 46 having a depending` chute 47 Each hopper 46 is pro- ,vided with a, gate `48 controlling the passage ofsand from the. hopper 46 through the chute 47 toga. Sand riddle comprising a hollow cylinder 49'revo1ubly mounted upon rollers 50, 5,0, and lactuated .by a shaft 5 1 having a bevel 'gear' 52 fixed thereon meshing with a bevel gear 52a provided upon roller shafts 52". The shaft 51 is actuated by means of a pulley 53, over which passes a belt* 54 extending over a pulley 55 mounted upon a driving shaft 56 connected by a belt 57 with a suitable source of power.

Below each sand riddle 49 is arranged an elevator boot 58 to receive the sand discharged from said riddles. lVithin each of said boots 58 is supported a shaft 59 having a sprocket wheel 60 thereon over which passes a chain belt 61 provided with buckets 62. The upper end of the chain belt 61 extends over a sprocket wheel 63 fixed upon a shaft 64 suspended in bearings from the ceiling of the second story of the building or structure. .i pulley 64 is fixed upon the elevator head shaft 64 and connefted by a belt 69 with a pulley 70 fixed upon the driving shaft 56. The chain belts 61 are inclosed by housings 65 from the upper end of each of which extends a chute 66 provided at its end with a gate 67 controlled by a. wheel 66 and chain 68.

Upon the upper floor 11, at each side of the carrier 15, are arranged pedestals 71, 71 to support the molds 80, S0 while the patterns are being formed therein.

The upper fioer 11 adjacent to the periphery of the carrier 15 is provided with a J hinged platform 72 which is provided upon its under side with an inclined projecting arm 73 adapted to contact with the arms or shafts 17, 17 on the carrier 15 as said carrier rotates in order to raise said hinged platform 72 sufficiently to permit the platforms 19, 19", ete. and the molds thereon to pass upwardly through the floor 11 when the machine is in operation.

The operation of the machine is as follows:

The first molds which are prepared upon the support 71 arranged upon the upper fioor 11 are placed upon the inclined tops 19, 19 of the platforms 19, 19, and thereupon the operating lever 41a is drawn toward the right (see Fig. 2) which will release the brake band 31 from its engagement with the pulley 30 through the medium of the arm 33, rod 34, arms 35, 38, and rod 39. The weight of the molds together with the metal therein supported upon the platforms 19, 19a is sufficient to overbalance the revoluble carrier 15 and cause the same to descend in the direction of the arrow a. Fi 1, as soon as the brake band 31 is released of its engagement with the pulley 30. As soon as the brake band 31 has been so released, the gear wheel 27, meshing with the gear teeth 16 upon the outer surface of the rim 15 of the carrier 15, will be caused to rotate and impart rotation to the pinion 26, shaft 25, gear wheel 24, which latter meshing with the pinion 23 upon the .shaft 22, will impart rotation to the brake pulley 30.

As soon as the carrierl has completed one ninth of a revolution, the lever 41u is again moved toward the left Fig. 2) whereby the rods 39, 34, and connected parts will be caused to resume their' initial positions, and the brake band 31 to engage with the surface of the brake pulley 3() under the action of the spring` 234iL provided upon the lower endof the rod `34, and thereby hold the carrier 15 to its adjusted position. In this position the platforms 19h, 19b will have assumed the positions previously occupied by the platforms 19a, 19a. At the same time the platforms l91,19d,will have been brought into position for loading at the opposite side of the carrier 15. As the carrier 15 is again caused to move one ninth of a revolution, the platforms 19", 19e may be loaded and metal poured into the molds thereon at the point where the platforms 19a, 19EL are shown at Fig. 1 of the drawings.` Thereupon the platforms 19f, 19S, 19h, 19i will 4be succes` sively brought into position for loading at the point indicated by the position of the platforms 19C, 19, and thereupon the molten metal poured into the molds on said platforms as the same are caused to assume the positions occupied bythe platforms 19, 19a.

is soon as the platforms 19e, 193 have assumed the positions previously occupied by the platforms 19, 19a, the latter will have come opposite to the tables 44, 44@L provided upon the platforms 43, 43 whereupon the molds may be removed from said platforms and the castings taken therefrom. The sand from the molds is then permit-ted to fall into the hoppers 46, 46, from which it is conducted through the chutes extending therefrom, and delivered to the riddles 49, 49 where the same is Worked over and discharged into the boots 58, 58 of the elevators from which it is thereupon conducted upwardly to the chutes 66, 66, and is ready to be used again in preparing the new molds.

In view of the time required in filling the molds as they successively come into positiony at the point where the platforms 19, 19'al are shown, the castings in passing from the position 19a to 19e, will have suiiicient time to cool and to permit of their removal from the molds and the handling thereof, as may be required.

It will be noted, that as my machine is simple in construction, and actuated solely by gravity, the operation thereof is easily controlled by means of a single brake mech anism, and operating lever therefor.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A casting machine comprising a revoluble member, a series of mold supports arranged thereon, a brake serving to control the speed of the movement of said revoluble member and to hold the same to its adjusted position, and means for actuating said brake whereby to arrest the movement of said revolublelmember to permit of the loading of said supports and the removal of the completed castings therefrom, substantially as specified.
