FRANCIS II. RICHARDS, OF HARTFORD, CONNECTICUT.

TRANSFERRING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 572,070, dated November 24, 1896.

Application filed August 1l, 1896. Serial No. 602,422. (No model) To a/ZZ whom, it may concern:

Beit known that I, FRANCIS H. RICHARDS, a

citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Transferring Apparatus, of Which the following is a specification.

This invention relates to a transferring apparatus of the class employed for transferring grain from one car to another car or to a warehouse, and which apparatus is generally known as and is termed a grain-transferring car.

One object of my present invention is to furnish an improved transferring apparatus of the class specified embodying improved cooperative instrumentalit-ies, the constructions, organizations, and coperations of which are such that grain or analogous material may readily be transferred from a source of supply-as one carto a remote place of deposit-as another car-in a progressivelyadvancing stream of uniform preregulated thickness and may be weighed in transita without retarding the progressive movement of said stream, and to accomplish this with rapidity and economy.

A further object of the invention is to provide, in connection with the supplying and weighing apparatuses in a transferring apparatus of the class specified, movably-supported receivers, traveling conveyers between the supply apparatuses and receivers, and valve mechanisms operable by a movement of said receivers for automatically controlling the supply to the conveyers, thereby facilitating a uniform operation in the cooperating mechanisms and obviating the clogging or overloading of the weighing mechanism usually accruing from an oversupply of material,and, furthermore, rendering the transferring apparatus automatically governable.

In the drawings accompanying and forming part of this speciication, Figure 1 is a sectional side elevation of a transferring apparatus of the class specified embodying my invention7 said figure showing the adjustable receiver or discharge-chute of the dischargeconveyer in an elevated position and in position occupied when the apparatus is in operation and is conveying grain from one car to another. Fig. 2 is a sectional'plan view of the transferring apparatus as seen from above in Fig. 1, the speelde-work representing the two streams of materialin their passage to and from the weighing-machine. Fig. 3 is a sectional side view similar to Fig. 1, on a relatively large scale,` showing the left-hand end portion of the transferring car or apparatus and more clearly illustrating the construction and organization of the different mechanisms. Fig. 4 is a sectional side view similar to Fig. 3, on the same scale, showing the right-hand end portion of the transferring car or apparatus. Fig. 5 is a front end elevation of the transferring-car on the same scale as Fig. Ll, parts thereof being broken away, and said figure also showing at the left and right hand, respectively, portions of a supplying and a receiving vcar and showing the connections-to wit, a flexible chute-between t-he transferring and receiving car. Fig. 6 is a cross-sectional view of the transferringcar, taken in dotted lines a o, Fig. 4, looking toward the right hand in said figure. Fig. 7 is a cross-sectional view of the transferringcar, taken on a line corresponding to the dotted line d d, Fig. 3, looking toward the right hand in said figure, parts of the mechanism being removed. Fig. 8 is a cross-sectional view, on a relatively large scale, of a portion of the framework or floor of the transferringcar, showing the supporting-platform for the weighing-machines and the instrumentalities in connection therewith for adjusting the weighing-machines and plat-form relatively to the oor-line of the transferring-car to bring the parts to the required level. Fig. 9

is a sectional side view of the parts illus-v trated in Fig. 8 as seen at the left of the dotted line c c in said Fig. 8. Fig. l0 is a sec-,- tional side elevation of a portion of the lefthand end of the transfer-car, showing the adjustable receiver or transferring-chute in its depressed or lowered position or in the position it occupies when the transferring-car is not in operation. Fig. 1l is a cross-sectional IOO receiver or transfer-chute of the dischargeconveyer.

Similar characters designate like parts in all the figures of the drawings.

As a preliminary to the general description of the constructions, organizations, and operations of the several cooperating mechanisms which comprise the transferring apparatus or transfer-car, it is desired to state that to avoid confusion in reading the drawings and more clearly to illustrate those features which are essential to the invention certain non-essential parts of the transferringcar-such as the trucks, brakes, and other elements common to ordinary ears-have been either wholly omitted or but partially illustrated in the drawings, and it will be understood that the car-body will be supported on the said trucks in any usual or suitable manner.

Inthe preferred form thereof herein shown and described the transferring apparatus, or transferring-cala as it may be hereinafter termed, comprises a transportable carrier or frame, herein shown in the nature of a bex-car bod-y 5V propelling mechanism for said carrier; a main-supply apparatus or hopper located near the delivery end of the transfercar with its receiving end in juxtaposition to the floor-line of the car; a so-callec intermediate-suppl y apparatus or hopper located near the opposite end of the car with its receiving end in juxtaposition t0 the floor-line of said' car; a so-called transferring receiver or chute7 movably supported above the main-supply apparatus inV juxtaposition to the roof of the ear; a so-callec intermediate receiver or chute movably supported above the intermediate-su ppl y apparatus with its discharge end preferably in close prox.- imi'ty to the roof-line of the car; a supplyconveyer, herein shown as the conveyer-'belt, supported upon suitable rollers and extending, with relation to the floor-line of the ear, from the main-supply hopper to the intermediate receivin g-ch utc; a discharge or delivery conveyer, herein shown as a conveyer-belt, supported upon suitable rolls and extending from the intermediate-supply hopper to the transferring-receiver and having its receiving and discharging ends located below and above the discharging and receiving ends of the supply-conveyer; actuating mechanism for the two conveyers; a valve or cut-off in shiftable connection with each of the supplyhoppers; a valve-actuating mechanism op'- erati-vely connecting the valve of the mainsu'pp-l'y hopper and the intermediate receiving-chute and operable by a movement of said chute for actuating the valveV to cut. olf or govern the main supply to the supply-'conveyer; a valve-actuating mechanism operatively connecting the valve of the intermediate-supply hopper and the movable transferring-receiver and operabler by a movement of said receiver for actuating the valve to cut oif the intermediate supply to the discharge-conveyer; weighing mechanism located between the discharge end of the supply-conveyer and the receiving end of the discharge-conveyer and having its receiving and discharging ends in juxtaposition to the discharge end of the intermediate receivingchute and the receiving end of the intermediate-supply hopper, respectively adjustable supporting instrumentalities for the weighing-machine; adjusting mechanismin operative connection with and effective for adj usting the transferring-receiver vertically with relation to the roof-line, and hand instrumentalities for operating the two valve mechanisms.

The transportable carrier for the coperative mechanisms ofi the transferring apparatus, which is designated in a general way by C, is shown somewhat similar to abox-car of ordinary construction, sa-id carrier comprisin ga box-like framework or housing in which is located` certain of the transferring apparati, and which box-like framework will in practice be carried in a manner simi-lar to the body portions of cars of ordinary construction uponsuitable trucks, of which the wheels 7 and axles 7' are shown in the drawings.

The carrier-frame or body portion of the transferring-car comprises in the preferred form thereof herein shown a suitable floor F,

embodying the usu al ilo or-su pportin g sills ,the

side walls S and S', the

end walls

9 and 9", and a suitable roof, which may be supported upon the side and end walls-of the car-body in any suitable manner.

lVhile it will be noticed that the floor and the side and end walls of the car-body are somewhat similar in a general way to like parts of cars of ordinary construction it will further be noticed by reference to the dra-wings that the construction of the roof of the car-body in the present instance is a radical departure from the construction of ordinary car-roofs. This roof, in the preferred form thereof hereinshown, com prisestwo roof-sections (designated in a general way by R and R2, respectively,) and one of which sections, as R2, constitutes an immovable part of the car-body, and the other of which sections, as R', is nlovably support-ed with relation to the roof-section R2 and is constructed to constitute a transferring receiver or hopper, as will be hereinafter more fully described.

Located at opposite ends of the floor F are two supply apparatuses, one of which is designated by Han d will beherei-nafter referred to as the main-supply apparatus or hopper,77 and the other of which is designated byy H2 and will be hereinafter referred t0 as the intermediate-supply apparatus or hopper, said hoppers being Open at their receiving ends to the interior of the car-body.

Movably supported above the intermediatesupply hopper H2, with its receiving end in juxtaposition to the roof of the car, is an intermediate receiver or chute, which is designated in a general way by R.

IOS

IIO

As a convenient means for transferring grain or other analogous material from the main-supply hopper H to the intermediate receiver R, I have provided a traveling supplyconveyer C, which in the preferred form thereof herein shown is in the nature of a conveyerbelt, carried at its opposite end upon suitable pulleys l0 and 10', whose shafts are supported in suitable bearings, as 12 and 12', secured to the framework of the carrier. This conveyer-belt is supported at an inclination to the plane of the floor of the car-body with its receiving end located below and in juxtaposition to the discharge end of the main-supply hopper H and with its discharge end in juxtaposition to and preferably slightly in advance of the receiving end of the intermediate receiver or chute R, and the material-carrying run of said belt is shown supported at suitable points in the length thereof by supporting-rolls or idle-wheels 13, mounted on carriers or shafts, which may be journaled in bearings (not shown) on the side Walls or other suitable parts of the car-body.

For the purpose of weighing the material as it is discharged from the chute or receiver R, I have shown located between the receiver or chute R and the intermediate-supply hopper I-l' a pair of weighing-machines (designated in a general way by P and P', respectively,) having,preferably,a combined weighing capacity slightly in excess ot' the supplying capacity of the supply-conveyer C'. It will be obvious, however, that one weighingmachine might be employed in lieu of two weighing-machines, providing the weighing capacity of said machine is sufficient to weigh the material as fast as it is supplied to the machine by the supply-conveyer.

Inasmuch as any suitable weighing mechanism capable of automatically weighin g and discharging material as it is supplied thereto may be employed in connection with the conveyer, I have, for convenience, shown in connection with the conveying mechanism of the transferring-car weighing-machines such as shown and described in Letters Patent of the United States No. 548,840, granted to me October 29, 1895, to which reference may be had for a more complete description of the construction and operation of this class of weighing-machines, and as both weighingmachines P and P shown in the drawings are substantially the same in construction, organization, and operation a brief description of one of said machines will suflice for an undestanding of its operation.

The framework for carrying the operative parts of the weighing-machine may be of any suitable construction, and is shown comprising two side frames or uprights 2 and 4, mounted upon a chambered supporting-base 3 and connected by a top plate 5, to which a suitable hopper-such as I-I-is secured by some suitable means. The base 3 carries suitable beam-supports for supporting the beam mechanism, which latter is shown consisting of a pair of oppositely-disposed counterweighted scale-beams B and B. The beam mechanism carries at proper points thereon suitable supports for the bucket, which latter is shown at G and is of the well-known single-chambered type. The bucket G will be so disposed as to receive the mass of material conducted thereto in the form of a supplystream from the hopper H.

The bucket-closer is designated in a general way byL and is shown pivoted at ,77 to the lower side of the bucket and adjacent to one side of the discharge-opening thereof, and having a counterweighted arm 79, preferably formed integral therewith for returning the closer to its closed position.

As a means for supporting the bucket-closer L an inverted toggle connection is shown connecting the closer and the bucket. form shown this toggle connection comprises the rocker 550, pivoted adjacent tothe upper rearward side of the bucket, and a connecting-rod pivoted to said rocker and also to the closer in such manner that when the closer is in its normal closed-position the two pivots of said connecting-rod or toggle member will be nearly in a line with and the uppermost pivot will be above the rocker-pivot.

A bucket-closer latch is shown at 82, piv-` oted to the bucket G in such manner as to engage the rocker 550 when the parts are in the closed position previously described. `In the embodiment shown the closerlatch 82 swings upwardly to engage the rocker 550, and it will be apparent thatsaid latch is released from engagement therewith by a downward movement. Y

As a means for releasing the latch 82 said latch is shown provided with a stop-pin 82', located in position to be engaged by a suitable actuator operable for depressing said latch. XVhen the latch 82 is thus depressed and disengaged fromthe rocker 550, the bucket-closer L will be free of restraint and the mass of material resting on the bucketcloser will force the same open for discharging the bucket-load.

As a means for controlling the supplystream which flows into the' weighing-ma- In the IOO IIO

chine I have, for convenience, shown said machine furnished with a valve that is similar to the valve described and claimed in Letters Patent No. 535,727, granted to me March pressure or movement, and as a meansV for effecting this operation a valve-operated actuator will preferably be employed.

The valve is shown carrying at the rear end thereof a relatively long` connecting-rod 558, which has formed -thereon at a suitable point the actuator 88, which, on the closure of the valve, will have a descending movement.

At the proper point in the operation of the machine the actuator S8 will be thrust downward into engagement with the stop-pin S2', carried by the latch 82, and succeeding the cut-olf of the stream said latch will be depressed, this action freeing the bucket-closer L in a manner previously described.

The particular construction and organization of the weighing-machines constitute no essential part of my present invention, as these may be materially modified or weighing-machines of other types be substituted.

As a convenient means for conveying the material from the intermediate hopper H2, into which it is discharged from the weighing-machines P and P', I have provided a traveling discharge-conveyer C2, which in the preferred form thereof herein shown is in the nature of a conveyer-belt carried at its opposite ends upon

pulleys

14 and 14,the one, 1i, of which is carried on a bracket 15, secured to the under side of the floor F below the intermediatesupply hopper H2, and the one, 14', of which has its shaft journaled in bearings on the transferring` receiver or chute R', which constitutes the adj ust-able roof-section, the upper run of said conveyerbelt being supported at suitable points in the length thereof on idle-wheels 13', whose carriers are supported in bearings (not shown) on suitable parts of the car-body.

The two traveling conveyers are shown disposed in relatively oblique transverse planes, with the receiving end r and discharging end r' of one conveyer located below and above the discharging end r' and receiving end r, respectively, of the other conveyer, each conveyer extending practically in an oblique plane from end to end of the canbody, as will be readily understood by reference to Figs. 1 to 4f, inclusive, of the drawings.

In contradistinction to the usual method of imparting traveling movement to endless conveyers as heretofore practiced, the conveyers C' and C2, herein described, are driven independently at points substantially midway of their lengths and in close proximity to the point at which the planes of said conveyers intersect each other. This is of considerable importance in the present instance, as it leaves the receiving and discharging ends of said conveyers entirely free of actuating mechanism and unobstructed, and, furthermore, secures an application of power at that point in the length of the conveyer where it is most needed and relieves the conveyer from the excessive strain inherent to conveyers of this class which are driven at the extreme ends of the runs.

As a convenient means for imparting a traveling movement to the conveyers C' and C2, I have provided, in connection with the two conveyer-belts, driving devices, (designated in a general way by D and D', respectively.) Each driving device, in the preferred form thereof, comprises three friction-

wheels

17, 17', and 17", which are supportedl for rotative movement side by side upon a suitable framework, as 18, with their axes' preferably in oblique ali-nement with and in a plane parallel to the plane of movement of the upper run of the conveyer, the'lowerrun of said conveyer being shown extended around the under face of the center wheel 17, which constitutes the drivingwheel for the conveyerbelt, and around a portion of the upper faces of the two wheels 17' and 17", which are located at each side of the wheel 17 and constitute frictional idle-wheels for retaining the bight of the lower run of the conveyer-belt in contact with the driving-wheel 17 under proper tension.

Inasmuch as the driving devices D and D'.

for the two conveyers C' and C2, respectively, are shown substantially the same in construction and are both operated from the same source of power and in the same manner, the description of one driving device, as set forth in the preceding paragraph, is deemed sufficient for an understanding of the construction of both driving devices, the only difference between said two driving devices being that they a-re set so that the outer faces of the

wheels

17, 17', and 17 of one driving device are at opposing angles parallel to and corresponding with the angular planes of the upper runs of the two conveyers.

As a convenient means for rotating the two driving-wheels of the two driving devices in relatively opposite directions to impart a traveling movement to the conveyer-belts C' and C2 a suitable motor (designated in agenera-l way by M) is provided, which has a power-shaft 20, on which is mounted a drivingpulley 21, which is belted to an intermediate d riving-pulley in normal fixed engagement with va counter-shaft 23, supported in bearings in a hanger 2l, preferably secured to the roof-section R2. This counter-shaft is furnished with two pulleysy 25 and 25', the one, 25, of which is connected by a straight belt 25" to a driving-pulley fixed to the shaft on which the driving-wheel 17 of the driving device D is mounted, and the one, 25', of which is connected by a crossed belt 25"' to a similar driving-pulley fixed to the shaft of the driving-wheel 17 of the other driving device D'.

The two conveyer-belts will preferably have a traveling movement of corresponding velocity, and a suitable clutch device E (see Fig. 2) will beV provided in connection with the counter-shaft 23 for releasing the driving- IOO lmay be supplied with steam from the boiler M', the connections between the boiler and engine and other details being omitted as not being essential to an understanding of this invention.

As a convenient means for propelling the transfer-car the power-shaft 2O of the motor is shown in dotted lines furnished with a sprocket-wheel 27, from which a sprocketchain 28 extends to an intermediate sprocketwlieel 29 on a counter-shaft 30, supported in suitable bearings of a bracket 3l, preferably secured to the under side of the floor F of the car, said counter-shaft being also provided with another sprocket-wheel 32, which is connected to a sprocket-wheel 33, secured to an axle v7 of one of the traction-wheels 7 of the car by means of a sprocket-chain 34.

If desired, a suitable clutch device (not shown) may be provided in connection with the power-shaft 2O for establishing and disestablishing the operative relation between the sprocket-wheel 27 and the power-shaft.

For the purpose of facilitating the adjustments of the weighing-machines with relation to lthe car-body to bring them to the proper level for successful operation and to secure a leveling adjustmentof said weighing-machines without disturbing the coperative relation between the hoppers of the weighing-machines and the receiving-chute R' of the supply-conveyer C', which is a matter of utmost importance in grain-transferring cars,

I have shown said machines supported upon a so-called platform, (designated in a general way by 132,) which comprises, essentially, two frames or supporting members and 36, one of which, as 35, constitutes the immediate support for weighing-machines and is shiftably supported by the other member, as 3G, for adjustment in an arc of a circle, concentric to a point p (see Fig. 6) between and adjacent to the receiving ends of the weighingmachines P and P., and the other member, as 36, of which is shiftably supported upon a suitable base, as 37, for adjustment in the arc of a circle concentric to said point p and transversely of the path of adjustment of the other member 35.

To facilitate the adjustment of the two carriers or supporting members 35 and 36, which constitute the platform for the weighing-machines, in relatively opposite directions and in the arc of a circle which is concentric to a point in the immediate vicinity of the receiving ends of the weighing-machine, the member 35 is furnished at opposite ends thereof with slides 38 and 39, respectively, whose working or bearing faces 38' and 39' are concentric to the axis of adjustment, or point p, of the weighing-machines, and the member 36 is provided at opposite ends thereof with guide blocks or supports 40 and 4l, whose bearing-faces correspond in curvature with the curvature of the bearing-faces of the slides 38 and 39 and cooperate with said slides for supporting and guiding the member 35 during the adjustment thereof; and as a convenient means for edecting this adjustment of the member 35 with relation to the member 3b' I have provided an adjusting-screw 42, which is rotatably seated and held as against longitudinal movement in anV oscillatory bearing 43, pivotally supported on a bracket 44, fixed to one end of the member 36, the inner screw-threaded end 42' of said screw having a screw-threaded bearing in an oscillatory bearing 45, pivotally secured to a bracket 46, fixed to the adjacent end of the member 35. This constitutes a simple and convenient means whereby the member 35, together with the weighing-machine, may have an adjustment in the arc of a circle in the direction of the double-headed arrow, or toward the right and left hand, as illustrated in Fig- 8 of the drawings, and as a convenient means for facilitatingthe adjustment of the member 36, together with the member 35, in the arc of a circle transverse to the direction of the adjustment described of said member 35 this member 36 is provided at opposite ends thereof, as shown most clearly in Figs. 8 and 9 of the drawings, with slides 50 and 5l, the working or bearing faces of which are in planes concentric to the common axis of adjustment p described, and the adjacent ends of the base 37 are provided with slideways or guideblocks 50 and 5l', which coact with and support the slides 50 and 5l. The adjusting device for this member 36 is shown comprising IDO IIO

an elongated adjusting-screw 52, which is journaled for rotative movement and held as against longitudinal movement in a bearing 53, fixed to the base 37, the opposite or inner end of said screw being seated in a screwthreaded oscillatory bearing 54, pivotally secured to a bracket 55,l fixed to the member 36 near the middle portion thereof.

In practice the member 35 will be provided, as shown in Fig. 8, with a bearing-plate 35', which is supported upon another bearingplate 36', secured to the member 36, this constituting a simple means for supporting the member35 at the middle portion thereof.

It will be obvious that if one weighing-ma'- chine only is employed the axis of adjustment p will be located near the upper end of said machine and inalinement with the center of the hopper II of said machine.

By the provision of means su ch as described for supporting and adjusting the weighing machine or machines I am enabled to secure a practically universal adj ustment,which enables me quickly to bring the machine or machines to the proper level, irrespective of the unevenness of said floor of the car caused by track or road depressions. Forinstance,if the floor-line of the car is out of true and the line of deviation is oblique to the longitudinal line of the ear, this would necessarily result in the deflection of the weighing-machines in a corresponding direction, and under these circumstances it would be necessary to adjust both supporting

members

35 and 36 more or less in opposite directions to bring the weighing-machines to a proper level.

Thus it will be seen that to secure accurate adjustment of the machine and brin g the same to a proper level said machine must necessarily be supported for adjustment in diversiiied directions, and this is what is accurately accomplished by my improved adjusting mechanism; and inasmuch as this is an important requirement in the art to which this invention appertains said adjusting mechanism constitutes an essential factor of my present invention.

The receiver R, through which the material passes from the supply-conveyer C to the hopper H of the weighing-machine, is shown pivotally supported near the lower end thereof at 5G between the arms of a bracket :57,secured to a beam 58, which extends over the weighing-machine and constitutes a portion of the framework of the carrier C, said receiver R being in the nature of a trough having a conduit or pipe 59 at the upper end thereof, the receiving end of which conduit is shown located slightly in advance of the discharge ends of the supply-conveyer C and the discharge end of which extends into the receiver or chute R, as shown most clearly in Figs. 1, 2, and et of the drawings.

As a convenient means for normally holding the receiver R in the operative positions shown in Fig. 1, and at the same time providing for the gravitation of said receiver on the overloading thereof, I have employed with said receiver a counterweighted device which in the form thereof herein shown comprises a rock-shaft G0, j ournaled in suitable bearings on the framework of the carrier; a counterweighted arm G1, secured to said rock-shaft extending outward from one side thereof; an oppositely-disposed arm G2, extending outward from the opposite side of said rock-shaft, and an operating-rod G3, connecting this arm 62 and the upper end of the receiver R. The construction and organization of this counterweighting device may of course be modiiied without departure from my present invention.

The transferring-receiver R`7-wh ich, when in its depressed position, as shown in Fig. 10, constitutes a portion of the roof of the caris pivotally supported upon the interior of the car, as shown at 65, at a considerable distance in the rear of the chute 71,3, which constitutes a part of said receiver, said chute being in the nature of a boX inclined toward the lower discharge end thereof, as shown in Figs. 1, 3, 5, and 10, and being provided with spouts or conduits Gl and 64:', located at opposite sides thereof and adapted to be connected by a flexible conduit, as G5, with an adjacent receiving-car, as shown most clearly in Fig. 5.

As a means for elevating and lowering the adj ustably supported transferring receiver R to accommodate the receiver to receivingcars of different heights, and at the same time provide for the automatic gravitation of said receiver in case the same should from any cause become overloaded, l have provided, in connection with said receiver, an elevating or adjusting device, (designated in a general way by 0,) and have provided, in connection with said elevating device, a counterweighted-elevating-device carrier adapted for normally supporting the carrier. in an elevated position and at the same time facilitating the gravitation of the carrier in case the receiver R becomes overloaded. The elevating or adjusting device O comprises, in the preferred form thereof herein shown, a slide 6G, supported for vertical movement in a slideway 67, secured to uprights 67 at the forward end of the ear, a bracket GS, having trunnions 69 and (59', supported in horizontal seats formed in the upper face of the two ears 90 and 90 of the slide 66, two intermeshing bevel-

gears

91 and 92, supported for rotative movement on the bracket GS with their axes at right angles to one another, the gear 91 of which is internally screw-threaded and the other of which bevelgears is shown provided with a crank 93 for turning the same, and a lifting-rod 9-l, which is screw-threaded at the lower end thereof and has a screw-threaded bearing in the internally-screw-threaded bevel-gear 91 and is pivotally connected at its upper end by means of diverging

straps

95 and 95 with the receiver R", as shown most clearly in Figs. 10 and 1l of the drawings.

The counterweighted carrier for the adjusting device O comprises, in the preferred form thereof herein shown, the rock-shaft 97, journaled in suitable bearings 9S and 9S', shown fixed to the floor of the car, and two oppositely-disposed arms 99 and 99', fixed at their inner ends to the rock-shaft, and the one, 99, of which is provided with a counterweight 99" at the outer end thereof, and the one, 99', of which is preferably provided with an antifriction roll 100 at the outer end thereof, which is held by the counterweight 99 in bearing engagement with the under side of the slide 6G of the adjusting device O, the

counterweighted arm 99 normally holding the arms 99, the slide GG, supported thereon, in an elevated position.

The pulley 1%',which supports the discharge end of the discharge-conveyer, is, as before stated, carried on the transferring conveyer R in close proximity to and slightly in the rear of the receiving end of the conduit or hopper h3. Thus it will be seen that when the receiver R' is elevated or depressed through IOC IIO

the medium of the adjusting mechanism O the discharge end of the conveyer C2 is carried with and always maintains the same position with relation to the hopper h3 of said receiver, as will bc understood by a comparison of Figs. 3 and 10 of the drawings.

The main and intermediate supply-hoppers H and l-l2 are shown provided with gatevalves 103 and 104, respectively, which are supported for sliding movement in suitable slideways formed in the side walls of the discharge ends of said hoppers, as will be understood by reference to Figs. 3, 4, 5, 8, and 9 of the drawings, which valves constitute elements of the valve mechanism hereinafter more fully described.

As a convenient means for automatically regulating or cutting off the supply of material to the receiving end of the two conveyers C' and C2, in case either one of the two receivers R or R' should from any cause become overloaded, and as a convenient means for effecting this end, as occasion may require, I have provided, in connection with the valve of the supply-hopper and with the receiver of each conveyer, valve-actuating mechanism, as hereinafter more fully described, of a construction and organization whereby a valve-closing movement will be automatically imparted thereto by a movement of the receiver and whereby a valveclosing or valve-opening movement may be imparted 'thereto independent of the movement of said receiver.

Preparatory to a description of the c onstruction, organization, and operation of the valve-actuating mechanism it is desired to state that the two receivers R and R', which control by their movements the valve-closing operation of the valve-actuating devices, are, as before described, counterweighted so as to sustain a predetermined weight of material and to have a gravitating movement when the load exceeds the weight-limit.

Each valve-actuating device is shown operatively connected with a receiver through the medium of the counterweighting device of said receiver and is operatively connected with a valve, and each valve-actuating device comprises in the preferred form thereof herein shown and described two valve-actuators (designated in a general way by V and V', respectively) shiftably connected together in such manner that the two actuators may have a unitary valve-closing movement, or one of said actuators may have a valve-closing movement independent of the movement of the other.

Inasmuch as the two valve-actuating devices are in a general way similar to one another, a description of one of said devices will suffice for both, and as a preliminary to such description it is desired to state that one of the actuating devices is shown suitably connected at one end to the valve 103 of the hopper H' and is pivotally secured at the opposite end thereof to an arm fixed to the rockshaft G0, and the other actuating device is shown pivotally connected at one end to the valve 104 of the hopper H2 and is pivotally connected at its operative end to an arm fixed to the rock-shaft 97.

Each valve-actuating device comprises, as before stated, two relatively-shiftable valveactuators V and V', one of which valve-actuators, as V, is pivotally connected at the outer end thereof with an arm 110, fixed to the rock shaft vof the counterweighting device, and is furnished at the opposite inner end thereof with an elongated bearing or slideway 112, and the other valve-actuator, as V', is pivotally connected at its outer end, as shown at 113, to the valve to be actuated thereby and has the opposite inner end thereof shiftably seated in the elongated bearing or slideway 112, this valve-actuator being one having a collar or abutment 114 a short distance from the extreme inner end thereof, which normally bears against the outer end of the elongated bearing 112 and constitutes a stopabutment against which the actuator V `abuts during the valve-closin g movement thereof to effect a valve-closing movement of the actuator V' in unison with the actuator V.

By reference to Figs. 1, 3, and 4 of the drawings it will be seen that the actuator V of one actuating device is slightly different in construction and organization from the actuator Vof the other actuating device, although the functions performed by both are the same. The actuator V of one valve-actuating device, as shown, comprises two principal members pivotally connected together by an intermediate lever, as 116, so as to have a movement in the opposite direction, as required inthe present instance, and the actuator V of the other valve-actuating device is shown comt.

prising one member which is pivoted direct to the valve actuated by said device, and the construction and organization of the valveactuator V' of the last-mentioned valve-actuating device is similar in a general way to the con struction and organization of the firstmentioned valve-actuating device, the only difference being that the two principal members of this valve-actuator are pivotally connected to the lever in such manner as to move in the same direction.

It will be understood that the construction and organization of the valve-actuators of the two actuating devices may bel materially modified without departure from this invention.

By the provision of valve-actuating mechanism such as herein shown and described it will be seen that when the load in thereceiver exceeds the weight-limit determined by the counterweighting mechanism said receiver will descend and actuate the rock-shaft of the counterweighting device, which will automatically impart a unitary valve-closin g movement to the actuators V and V' ofthe valve-actuating device, causing said actuators to close the valve of the supply-hopper.

As a convenient means for normally retaining the two valve-actuatorsof each actuating device 1n` such cooperative relation that a valve-closing movement cf one actuator will Y normally operate the other and as a means for facilitating the operation of one actuator independently of the other I have provided, in connection with one valve-actuator of each actuating device, counterweighted or reactionary hand operable instrumentalities, which instrum entalities, in the preferred form thereof herein shown, comprise a hand-lever 11S, fixed to a rock-shaft 119, and a bell-crank 120, fixed to said rock-shaft and having one arm thereof pivotally connected by a suitable connecting-rod 121 to the valve-actuator and having the other arm thereof connected to a retracting device, such as the weight 123. These instrumentalities constitute a simple and convenient means whereby the two actuators will be normally held in engagement for unitary operation, and whereby one or both of the valve-actuators may be arbitrarily operated irrespective of the position of the receiver. These operating instrumentalities for the valve-actuator may be variously modiilied within the scope of my invention, and therefore I do not desire to restrict this invention to any particular construction .and organization of mechanism for accomplishing` this end.

As a simple and convenient means for supplying mateerial to the main supply apparatus II from an adjacent car, I have shown, in cooperative connection with the actuating mechanism for the two conveyers C and C2, a power grain-shovel apparatus of the wellknown Coker and Metcalf type, the construction and organization of which is so well known in the art that a detail description thereof is deemed unnecessary for the purposes of my present invention, especially as this feature specifically constitutes no part of my present invention.

The grain-shovel apparatus, which is d esignated in a general way by IV, is shown comprising a winding-drum 125, supported in suitable bearings above and substantially midway between the side frames of the door (l of the car; a rope 126, carried on said drum extending over a pulley7 127, journaled on a bracket secured to the iioor F of the car; a scoop or shovel 12S, secured to the outer end of the rope 126; and a shaft 129 for driving said drum, which shaft is journaled in suitable bearings on the framework of the car and has a bevel-gear 130 in mesh with another bevel-gear 131. (Shown in dotted lines in Fig. 1 and in full lines in Fig. 2.) Said lastmentioned bevel-gear is fixed to a shaft 132, journaled in suitable bearings on the framework and having a driven pulley 133, which is connected by a belt 134 to a driving-pulley 135 on the counter-shaft 23, which is rotated, as hereinbeforc described, from the powershaft 2O of the motor M.

The drum 125 of the shovel mechanism will in practice he furnished with the usual mechanisms for establishing and disestablishing the effective relation between said drum and the driving-shaft 129, so as to facilitate the n operation of the shovel 12S.

In the operation of the transferring mechanism grain is conveyed by the power-shovel from an adjacent car to the main supply apparatus I-I of the transferring-car, is thence conducted by the supply-conveyer C' to the receiver R, the momentum acquired by the grain in passing from the lower to the upper end of said conveyer causing the -grain to be projected through the chute or conduit 59 into the receiver R, from whence it is 'delivered to the hopper H of the weighing-machine, where it is weighed and then delivered through the intermediate supply apparatus to the receiving end of the discharge-couveyer and is progressively advanced and delivered into the hopper hg of the receiver R', where it is conducted by means of the conduit or transfer part 65 to the receiving-car at the opposite side of the transfer-car, as will be readily understood by a comparison of Figs. 1, 2, and 5 of the drawings. The supply to the two conveyers isautomatically controlled by the supply regulating or controlling mechanisms comprised in the valves and valve-actuating devices.

As a convenient means for facilitating the delivery of grain or other analogous material directly to the weighing-machine, to be conveyed therefrom to another place of deposit, as is sometimes advantageous when transferrin g grain from a warehouse to a car, the upper end of the receiver R is shown open at 136 and the roof of the car has a covered opening 137, through which aconduit (not shown) may be extended direct from a warehouse. This will obviate thc necessity for conveying the grain from the main supplyhopper I-I to the receiver R, and consequently effects a saving of time required for transferring the grain.

As clearly illustrated iu the drawings, the upper part of the receiver R constitutes, when said receiver is in the position shown in Fig. 10, a roof-section of the car, the upper face thereof coming approximately in alinement with the upper face of the runningboard of the main portion of the car-roof, and by the construction and organization thereof hereinbefore described the receiver may be elevated by means of the elevating or adj usting mechanism O, as before stated, to

a suitable height to facilitate the transfer of grain by gravity from said receiver to any car of ordinary height and also permit the receiver to be lowered sufficiently to readily pass under any bridge that the main portion of the car can pass under.
