GRAIN-STORAGE ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 572,726, dated December 8, 1896.

Application filed August 8, 1894:. Serial No. 519,764. (No model.)

To all whom it may concur-rt:

Be it known that we, MARQUIS F. SEELEY and JENNIE Y. SEELEY, of Chicago, in the county ofOook and'St-ate of Illinois, have invented certain new and useful Improvements in Grain-Storage Elevators; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in storage-houses for grain, or what are commonly known as grain-elevators, and more particularly to devices adapted for usein connection with the storage receptacles or bins of such houses for handling the grain in re ceiving and shipping the same or for transferring it from one to the other of several bins or receptacles.

- A grain-handlin g apparatus embodying our invention consists in its principal features in a lift or elevator-platform by which a car loaded with grain may be carried from the level of the ground to a point above the tops of the storage-bins, a dumping-platform 0r tipple also located above the tops of the bins and adapted to receive loaded cars from the elevator-platform, a wheeled hopper or receptacle adapted to receive the grain when discharged from the car by the use of the tipple, and railway-tracks located above the level of the tops of the bins on which the wheeled hopper is adapted to run and along which said hopper may be shifted to a point over any one of the bins in the building, so as to discharge the grain directly therein.

The features above described alone constitute a means for receiving grain from railway-cars, but for the purpose of transferring from one bin to another and for shipping or loading into a car or vessel from either bin the same device may be used in connection with the usual arrangement of railway-tracks and discharge-spouts at the lower ends of the bins, so that grain may be discharged from either bin into a car or hopper placed on the elevator-platform and thereby lifted to the tipple, in case it is a carof ordinary construction, or to the railway-tracks in case it is a hopper-bottomed or self-discharging car, it being of course understood in this connection that in loading cars or vessels the grain will be discharged into a bin the bottom of which is located a considerable distance above the ground and whichis provided With a discharge-spout through which grain may be con ducted to a car or into the hold of a vessel.

The invention may be more readily understood by reference to the accompanying drawings, in which Figure 1 is a View in cross-section of a storage structure embodying ourinvention, taken on line 1 1 of Fig. 2. Fig. 2 is a longitudinal vertical section of the same, taken on line 2 2 of Fig. 1. Fig. 3 is an enlarged detail side elevation of the dumping device or tipple. Fig. 4 is an end view of the same. Fig. 5 is a detail cross-section taken on line 5 5 of Fig. 3. Fig. 6 is a plan view of the elevator structure, showing the track-rails and bins, but omitting the parts above the same.

As shown in said drawings, A A A indicate the storage-bins, which are formed in the usual manner by outer walls A A and intermediate walls or partitions A A The outer walls A" are shown as extending to the ground, and the intermediate walls A are supported on posts a a, said intermediate walls or partitions terminating at the level of the bottoms a a of the bins in the usual manner. Said bottoms are made of hopper shape and provided with exit-openings a 0. through which grain may be discharged through suitable spouts, or otherwise, into cars located on the tracks B B, extending beneath the bins. Above the level of the bins is formed ahousin g or inclosure consisting of side walls A A and a roof A such housing serving to inclose and protect the apparatus by which the grain is delivered to the bins, as heretofore common in similar structures.

To now refer to the novel features of construction embodying our invention, the storage house or structure is provided with a power-lift or elevator having two verticallymovable cars or cages, (indicated by C C in Fig. 1,) the same being adapted to move vertically in shafts or passages D, located in one end of the elevator structure. Said cars may be actuated by any suitably-applied hoisting device, such, for instance, as hydraulic machinery commonly used for freight and passenger elevators. As herein shown, the cars C C consist of platforms connected by tierods 0 c with overhead frame-bars O, to which are attached hoisting-ropes G 0 which pass over guide-pulleys c c at the upper ends of the shafts and thence over other guide-pulleys c c to the hoisting-engine. When two elevator cars or platforms are employed, as shown, they will commonly be arranged to counterbalance each other by means of the cables shown-or other suitably-arranged connecting-cables passing over pulleys at the top of the building, so that the weight of an empty car resting on one platform could be utilized to aid in lifting the loaded car on the other platform, an obvious advantage of this construction being that the weight of each descending car is utilized to lift an ascending car, so that the work done by the hoistingengine is that of elevating only the grain, with which the ascending car is loaded.

When the platform 0 is at the lower end of its movement, the tracks with which it is provided are at the level of the ground and in rectly upon the elevator-platforn1,wl1ich latter 1 is made of such size and length as to easily receive railway-cars of the size ordinarily employed.

E E indicate as a whole two dumping devices or tipples which are located at the upper part of the elevator structure at a considerable distance above the tops of the bins and adjacent to the elevator-shafts. The platforms E E of said tipples are located on the same level or approximately the same level with the elevator-platform when the latter is at the upper limit of its movement, so that cars may be transferred from said elevator-platforms E E to the tipples. The transfer of the cars from the elevator-platforms to the tipples may either be direct or through the medium of an intervening stationary section of track, the result being the same in either case.

For simplicity of construction we have herein shown the tipples as located adjacent to the elevator-shafts without any intervening tracks, the ends of the tipple-platforms being arranged to reach the sides of the shafts, so that they extend to the elevatorplatform, and the cars may be run directly from the track-rails on the platforms of the elevators to those on the platforms of the tipples.

Each of the tipples referred to is con structed as follows: G indicates as a whole a supporting-framework which rests on the upper edges of the partition-walls of the bins and which supports the tipple at a con- I siderable distance above the same.

On the top of the said framework rests a horizontal metal frame or platform G, at each side of which is a rigid standard G The platform G and standards G G are preferably made of rolled-metal girders and plates, and latedge.

eral stiffness is given to the standards by means of aconnecting brace or braces, herein shown as having the form of a transverse plate g, stiffened by angle-irons at its upper At the upper ends of the standards G G are formed journal-bearings g g, adapted to receive short axles or journals h h, which are attached to a swinging frame H, by which the tipple-platform F is sup ported. The pivotal axis on which the said frame H swings is arranged at right angles to the track-rails 011 the platform F, so that when said frame H'is swung about said pivotal axis the ends of said platform will be raised or lowered. Furthermore, said platform F is mounted on the frame H in such manner that the platform may be tipped or inclined laterally, the device herein shown for this purpose consisting of transverselyarranged curved supporting bars or rockers F F, attached to the platform Fand adapted to rest and roll on transverse ways H H on the frame 1-1. This construction of the parts which support the tipple-platform obviously will permit a car resting on said platform to be tipped in two directions, namely, both en'dwise and sidewise, thereby providing means by which all of the grain in an ordinary box or grain car may be discharged from one side door thereof, it being obvious that if the car he first tipped sidewise by the tilting of the platform F on its longitudinal axis a considerable part of the grain will flow through the central door, and that if while the car is thus held in a sidewise-inclined position the frame H is then swung on its pivotal axis, so as to first lower one end and then the other end of the car, the grain remaining in the ends of the car after it has been tipped sidewise will be discharged or poured from the central door.

' It is of course understood that the two movable parts of the tipple, namely, the platform F and the frame H, can be so arranged as to permit an inclination of the-car sufficient to insure the discharge by gravity of practically all the grain therein.

The frame H of the tipple is shown as consisting of two longitudinal side pieces H H which extend outside of the supportingstandards G G2 and which are connected at their ends by cross-pieces 11 H On these cross-pieces H 11 rest the tracks or ways H H. Said cross-pieces H are extended at one side of the frame H a considerable distance past the frame-piece H in order to afford proper support for the outer end of said ways H. The pivot studs or journals 7?, are preferably located at a considerable distance vertically above the longitudinal side pieces H of the frame, and said studs are connected with the said side pieces by vertical ribs H which are suitably stiffened by an gle-irons, and which are preferably extended throughout practically the full length of the frame, so as not only to afford connection between the pivot-studs and frame, but to give longitudinal stiffness to said frame. The location of the pivot-studs above the main part of the frame H on which the ways H H are supported brings the pivotal axis on which the platform F and the car swing at a point near the bottom of the car, and therefore much nearer the center of gravity of the platform and car than would be the case were the pivotal axis located at a level with or below the said platform. The platform F, furthermore, is arranged to rest directly on the transverse supporting bars or rockers F, so as to bring the track-rails as low as possible and the center of gravity of the car and platform as near as possible to the center of curvature of said rockers, it being obvious that if the center of gravity of said parts were coincident with the center of a circular curve conforming to the bearing-surface of the rockers such cen-l ter of gravity would be. neither raised norlowered, but would move in a horizontal line in tipping the car and platform laterally, and

this work could then be accomplished by a minimum eifort. In practice we propose to make the curvature of the said rockers such as to bring the center of curvature as near as practicable to the center of gravity of the car and platform. By bringing the platform F as near as possible to the bottom of the said rockers, furthermore, we are enabled to bring the center of gravity of the car and platform much nearer the transverse pivotal axis of the frame H than would be the case were the said platform elevated a considerable distance above the main part of said frame. As will be clearly seen from Figs. at and 5, the arrangement of the pivots or journals h h above the level of the platform F and frame H makes it necessary that the supporting-standards G G should rise between the frame-bars of the platform and the side bars H H of the frame H. This construction, however, is unobjectionable and does not interfere with the tipping of the car, because the said standards G G and the elevated parts of the frame H come opposite the center of the car and between. the wheels thereof, so that the car-body passes over said V which supports it, both the rockers F and the ways H are provided with gear-teeth h f, which remain constantly in mesh with each other .and prevent any lateral movement, slipping, or shifting of said platform relatively to the frame. The rockers F are provided with flat or straight portions extending from a point beneath the center of the platform to the'side of the platform opposite that at which a curved part of the rocker is located, such straight parts serving asa stop to limit the backward movement of the car when the platform is being restored to its horizontal position and preventing the tipping of the platform in the wrong direction. Similar straight parts or surfaces at the outer ends of the rockers serve to limit the tipping of the car when inclined, and thus avoid possibility of the platform F becoming dislodged from its place 011 the platform H.

To hold the car on the tipple-platform F when operating the latter, we have provided devices as follows: At the end of the said platform remote from the elevator-shaft we place two strongly-braced uprights F F,

which are connected by a cross-piece F carrying a coupling-block f, which is provided with a coupling-pin or other means corresponding with those commonly employed on cars, by which the car may be engaged with the coupling-block in the same manner that it is coupled to an adjacent car on a train. The standards and cross-piece in themselves hold the car from endwise movement when that end of the platform at which these parts are located is depressed, and the coupling devices hold the car from moving toward the opposite end'of the platform when such opposite end is lowered. To hold the car from tipping sidewise under the action of gravity when the tipple-platform is laterally inclined, we have provided two rigid standards F F, which extend upwardly to the sides of the car in position to engage the same upon a very slight movement thereof from its central position on the car-tracks. If desired,

blocks or wedges may be inserted between I the standards and the sides of the car after the car is in place on the platform, but commonly this will not be necessary. The standards F F are shown as rising from and as being attached to the supporting-rockers F of the platform F.

The two movable members of the tipple described, namely, the platform F and the frame H, may be moved by any suitably-ap plied actuating device adapted for operation either by hand or power. As a simple and convenient means of effecting such actuation of the parts of the tipple we have shown hydraulic cylinders I and J, arranged to operate the platform F and frame H, respectively. Such hydraulic cylinders when employed may be supplied with water under pressure from the same power plant by which the elevatorplatform is actuated. We have shown in the drawings a hydraulic cylinder I arranged at each end of the frame H and as provided with a piston 11, connected with a cross-piece on the frame F in such manner that the outward or upward movement of the piston-rods will lift the inner edge of the platform, and thereby cars by the operation of the dumping devices described, we provide one or more hoppers K,

which rest on a truck K, provided with sup- 3 The truck referred to is arranged to rest and run on track-rails L L,

porting-wheels 7c 70.

which are located at either side of the tipples at a sufficient distance below the same to bring the top of the hopper in position to receive the grain discharged from the cars on the tipple, and said tracks L L are extended throughout the length of the storage structure, over the tops of the bins thereof, and will be provided with suitable connecting tracks or switches L L, Fig. 6, by which the hoppers may be transferred from one track to another and thereby carried to a point over any one of the bins into which it may be desired to discharge the contents of the hopper. Guards or shields M M serve to confine the grain which is discharged from the car-door and insure its delivery to the hopper K. Said hopper is provided with an inclined bottom and with a lateral door or gate by which the grain therein maybe discharged by gravity. \Vhen necessary to secure the discharge of the grain from the hopper into a bin beneath the track on which thehooper is located, a deflectingboard is provided, as clearly seen in Fig. 1.

As far as the transfer of the grain from the dumping device or tipple to the several bins is concerned, the hopper K may be of any preferred construction, but to provide for the weighing of the grain as it is stored we provide a scale attachment, which may either consist of a track-scales applied to a section of track on which the hopper rests or a hopperscales resting on and carried by the track K, which supports the hopper. This latter construction is shown in the drawings, wherein 0 indicates the scale-beam.

The parts above described obviouslycon stitute a complete device for receiving, weighing, and storing grain, the loaded cars as they are brought to the elevator being placed on the elevator-platform, lifted to the top of the building, shifted upon the tipple-platform, and then tipped or inclined to secure the discharge of the grain from the car-door in the manner above described. The grain as it is discharged from the car is received into the hopper K, is weighed while within the hopper, and the hopper then moved or shifted along the track-rails until above or opposite the bin in which it is desired to store the grain, the grain being then discharged into the bin.

The features of construction described constitute efficient means for transferring or shipping the grain as well as for receiving and storing it. For these purposes we propose to employ a transfer-hopper P, Fig. 1, adapted to run on the track-rails B B beneath the several bins. Said hopper will preferably be open at its top and also have a side door or gate 1:). To transfer the grain from one bin to another by the use of said hopper P, the latter will be placed beneath the bin from which the grain is to be taken and the latter discharged into the hopper through the exitopening a a spout, as indicated by a Fig. 1, commonly being used to direct the grain into the hopper. The said hopper will then be shifted to one of the elevator-platforms and lifted to the level of the tipple, on which it will be run and its contents discharged therefrom into the Weighing-hopper in the same manner as in the case of an ordinary car. By the use of the weighing-hopper, or any ordinary hopper in case it be not desired to use the weighing-hopper for this purpose, the grain maybe moved to a desired bin and discharged therein.

For shipping grain from the elevator the same may be conveyed in the manner described to an elevated bin or shipping-pocket Q, having a descending discharge-spout Q, through which the grain may be discharged either into the hold of a vessel or into cars in the manner as heretofore common.

In case it is desired to employ the features of construction described for receiving the grain only, other means maybe provided for transferring the grain from one bin. to a11- other or for delivering the grain to a vessel or cars in shipping; as, for instance, where the several bins extend downwardly to the ground-level, as is common in some storageelevators, a horizontally-arranged. transferbelt may be employed for moving the grain horizontally in connection with suitable devices for elevating it, or grain may be conveyed from a storage-bin to another bin or to a car or vessel by pneumatic pressure. It is to be noted, moreover, that the apparatus described, namely, an elevator-platform or hoist, a tipple at the top of the building, and a weighing or transfer hopper running on tracks above the bins, may be employed for transferring and shipping alone when other devices are used for receiving and storing the grain. Furthermore, if the bottoms of the bins are located at the ground-level, short elevators or conveyers may be employed for lifting the grain discharged therefrom and delivering it to cars or hoppers which rest 011 track-rails at the ground-level, and such cars or hoppers may be lifted to the top of the building in the manner as hereinbefore described.
