WEIGHING-MACHINE.

SPECIFICATION forming` part of Letters Patent No. 628,926, dated July 18, 1899.

Application iiled December 31,1898. Serial No. 700,777. (No model.)

To all 'lu/tom it 'nm/y concor/t:

13e it known that I, CELEsrEN DELAE'r, a citizen of the United States,residin g at Shel by, in the county of Polk and State of Nebraska, have invented a new and useful lVeighing- Machine, of which the 'following is a specifi cation.

My invention relates to improvements in automatic weighing-machines; and one object in view is to provide a simple and cient mechanism which may readily be adapted to an ordinary elevator to receive grain therefrom, determine by weight the proper quantity of grain, and deliver `the latter to a suitable vehicle or car, the apparatus being actuated solely by gravity, and thereby disn pensing with a power mechanism. o,

A further object ot' the invention is to pro vide the weighing mechanism with means which checks or retards the partial rotation of a pocketed drum at a proper point to receive grain from the elevator, to provide means for positively shutting oit the flow of grain when one pocket in the drum shall have become iilled and the drum is partially rotated on its axis to bring another pocket into position below the elevator-spout, and to provide a delivering device which may be adj usted to discharge the grain into the desired direction.

'Vith these ends in view the invention consists in the novel construction and arrangement of parts and in the combination of devices which will be hereinafter fully described and claimed.

To enable others to understand the invention, l have illustrated the same in the accompanying drawings, forming a part of this specification, and in which Figure 1 is a perspective view of a grainn weighing machine embodying my invention and showing it applied to a part of a grainelevator. Fig. 2 is an elevation looking at the reverse side of the machine from Fig. 1. Fig. 3 is a front elevation, and Fig. t isa vertical sectional elevation on the plane indicated by the dotted line 4 et of Fig. 3.

Like numerals of reference denote like and corresponding parts in each of the several ligures of the drawings.

My weighing-machine may be used in con nection with any ordinary elevator, and in the drawings the boot or casing of the elevator is represented at 10. As no novelty for the elevator or its casing is set up in this application, l do not consider it necessar'y to specifically describe these parts. As is usual, the head of the elevator boot or casing has a delivery-opening 11, and the spout 12 partially surrounds this delivery-opening in order that the grain which may be discharged by the elevator through the opening 1l may pass into the spout 12, that serves to direct the grain into the revoluble pocketed drum, which forms one of the elements of my weighing-machine. The spout 12 is provided with an inclined bottom 13, which overhangs the pocketed drinn7 and said drum is supported by horizontal brackets or arms 14, which are lirinly secured to the boot or casing 10 on opposite sides thereof. These brackets or arms are provided with journal-bearings 15, which receive the transverse shaft 16 of the revoluble drum. The drum of my invention is constructed peculiarly to provide a plurality of pockets which are equal in capacity and receive the grain from the spout through offstanding open mouths that are presented successively to the spout on the rotation of the drum. This drum consists of the head 17, provided with the offsets 18 at equidistant points, the partitions 19, and the shell-sections 20. The partitions are suitably secured within the drum to form, with the heads and the shellsections, a plurality of pockets or compartments 21, and the sections 2O of the shell or casing are secured to the offset edges of the head 17 in order to make the sections 2O occupy an eccentric relation to the drum-shaft. lt will be observed that each section of the shell or casing extends from the abrupt edge of. one pair of offsets 18 on the drum-heads to the outer edges of the next adjacent pair of ollsets 18, and the contiguous edges of the sections 2O of the casing are thus disposed a short distance from each other to provide the open mouth 22. A series of these open odset mouths 22 are provided around the drum, and each mouth opens into one of the pockets or compartments 21 of the drum.y The drumhead 17 is secured firmly to the shaft 16 in order that the shaft and the drinn may rotate IOO together, and this shalt is iitted properly in the bearings of the brackets la in a nianner to actuate the scale-lever and the register.

One end of the drum-shaft is extended beyond its bearing for the reception of an armed operating-plate 23, which is secured iirinly to the shaft to rotate therewith, and this operating-plate has a series ot radial fingers 2l, which correspond in number to the pockets ofthe drinn. The graduated scale-lever 25 is fulcrumed at a point intermediate of its length, as at 2G, to one of the brackets or arms in a manner to provide a short arm 27 on said lever, and an adjustable weight 2S is iitted to and adapted to be clamped on the long arm of the scale-lever, so as to be shittable thereon toward or from the fulcrum 2G. The sliort arm 27 of the scale-lever lies in the path of the radial fingers on the plate 23, and. when one compartment of the drum has been filled With grain up to the desired quant-ity the Weight ot the grain causes the finger on the plate 23 to lift the lever against the gravity of the eounterpoise 2S, thereby tripping the leverand permitting the lingerot the plate 23 to clear the short lever-arm in order that the drum may rotate partiallyT to discharge the grain from the filled pocket and to present an empty pocket in position below the spout 12 to receive the grain from the latter.

To overcome any tendency of the revoluble poclieted drum from moving in a backward direction after or during the discharge of the grain from its filled pocket, and thereby move the drum to a position where the mouth 22 of the pocket which should receive the grain tvould be out of alinement With the spout, I provide a detent mechanism, which consists of a cheek-spring 29 and a series of spaced lugs 30. These lugs are on-one of the drum-heads at a proper distance from the oiset portions 1S thereof and from the open mouths The spring 2S is supported by one ot' the brackets or arms lt to lie in the path of the lugs 30 and at a proper distance below the position assumed by the mout-h on the drum when it is in operative relation to the spout 12.

The head of the drum opposite to the head having the lugs 30 is provided with a series of cams 3l, arranged eccentri'cally one to the other and parallel to the sections 2O of the drum shell or casing, and these cams are adapted to actuate a valve 32, that is arranged across the spout l2. The valve 32 is carried by a rod 32E, which is supported in bearing-plates 34, attached to the sides of the spout l2, and the edges of this spout are inclined or beveled, so that the valve ina-y be pressed against the saine in order to securely close the spout during the period ot rotation of the pecheted drum. The valve is hung so that it will open by gravity, and in order to close the valve automatically across the spout I provide it with a yieldable arm 35, which is adapted to ride upon either of the series of cams fll. The arm 85 consists, preferably, ol:

l hopper.

a spring that is secured to the gravity-valve 32, and this arm depends from the valve to assume a position where it will ride upon the cams 3l successively. Then the drum assumes a posit-ion for the mouthv of one of its pockets to lie immediately below the spout l2, the yieldable arm is free from engagement with the cams and the valve opens by gravity for the grain to pass from the spout into the pocket of the drum. As the drum begins to turn, owing to the accumulation of a proper quantity of grain in its pocket to overcome the counterpoise on the scale-lever, one ofthe cams 3l engages with the arin 35 to close the valve across the spout l2, thereby shutting off the continued llow ot grain 'from the spout to the drum, and this cam remains in engagement with the valve-arm until the drum rotaies sufficiently to present the mouth oit an empty pocket below the spout, at which time the cam clears the arm 35 and the valve again opens by gravity.

To the end of the drum-shaft opposite to the operating-plate 23 is secured a register- Wheel 3G, that is constructed with a series of teeth 37, corresponding in number to the pockets oi the drum. The Wheel 3G is actuated on the rotation of the drum, and its teeth operate the totalizing-Wheels of a register 3S. In practice the revoluble druin may have its pockets or compartments proportioned to receive and contain a halibushel oi' grain, and the register-Wheel 36 is actuated each time that a half-bushel of grain is discharged from the drum; but it Will be understood that the capacity of the drum may be varied and the indication by the register is correspondingly changed.

The revoluble drum discharges its contents into a hopper 39, which is arranged below the drum and is supported by arms or brackets a0, secured to the elevator boot or casing l0. This hopper supports a chute ltl, which is arranged to receive from the bottom of said hopper, and to enable the grain to be discharged in any desired direct-ion the chute tl is connected adjustably, as at i2, to the The angle of the chute in relation to the hopper may be changed to deliver the grain at either side or at the front end ol the Weighing mechanism, and this chute is thus adapted to properly deliver the grain into a Wagon or car.

In order to prevent the scale beam or lever Vfrom dropping out of operative position, I provide a stop pinor shoulder 25. This pin or shoulder is arranged, preferably, on the bracket It, as shown by Fig. l, slightly be low the horizontal plane of the lcver-fuleruln 2G, so as to lie in the path of the lever er beam 25 for the lever to rest on the stop pin when it is free from the lugs of the armed plate 23.

Changes may be made in the form and proportion of some ot the parts, While their essential features are retained and the spirit of the invention embodied. IIence I do not desire 'to be limited to the precise forni of all.
