To wllnwham it may concern:
Be it known that I, JOSEPH E. CAMP, a citizen of theUnited States, residin at Washington, in the county of Tazewel and State of Illinois, have `invented certain new arid useful Improvements 'inl Dumps; and I do herebydeclare that the following is a full, clear, and exact description 'side elevation of the dump Wit of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to 'improvements in portable grain-dumpa` j The object of the invention is toprovide a light, inexpensive, but efficient grain-dum of the portable kind which will be under pe ect control while in use.
In the appended drawings, Fi e 1 is a shown thereon.. Fig. 2 is a plan view of the Fi 3 is a sectional elevation of the wagonwheel resting thereon and a frame in contact with the wheel and used to raise the front end ofthe wagon. Fig. 4 is a View of la gearingused with the dum ,part being shown in section. Fig. 5 is a face view of an internally-toothed gpm-wheel, showing other gears used therewit f "'The platform of the dump is indicated by the letter A, lthe same being rovided near one end withwheels B, the ot er end with a tongue C, to which horses may be hitched for transportation purposes. Erected upon the platform at each edge is a de rrick-frame D, on the forward limb of each of which a frame E, carrying rollers F, is designed .to travel.
Said frames E are attached to a Wagomraising frame G, normally seated in the latform A,'lush'with the u per surface of t e same. Atthe top of each errick-frame is a grooved pulley H, over which runs a cable I, one end of which is attached to the frame E, the other A end having connection with 'a drum J on a shaft K, having bearings in the sills of the platform, in anygood manner, but Vnot shown.v One endof the 'shaft K is provided with a worm-wheel L, with which engages a Worm M, carried on a two-piece shaft composed of two abuttin portions N and N', journaled at one side of t e platform at right angles to the shaft K The part shaft N is driven from the'power (not shown) by means of a bolt Ol and pulley P. Secured to the part shaft N is an internallyetoothd drum S--for instance u by a key T, as shown.. The end of the Portable Graina Wagon other shaft portion N terminates within the hub of the drum S adjacent to the end ofthe shaft N, a's clearly shown in Fi 4. This end of said shaft- Nis provided wit a pinion-gear U, aflixed thereto in any suitable 1nanner-- for instance, as by a key-and adjacent to said inion and loose on the shaft is an varm V, w` ose extremity carries a gear W, enga ing the teeth of the drum S and the pinion L. A jacent also to the arm is a loose sleeve Y, adapted to shift yalong the shaft, for the purposes to be hereinafter described. Pivoted i on a yoke R, secured to the platform A, is an arm X, whose lower end is connected to the saidshifting sleeve Y b -a link Z. The upper end of the arm X as loose connection with a hand-lever 2, pivoted on said yoke R or to any other part of the machine desired. Said arm X also pivotally connects with a pushrod 3, guided in a raised portion 4 of the yoke, as shown in Fig. 5. A fork 6 is loosely carried by the sleeve Y and has an arm 7 at right angles to its length parallel to the shaft' N, as shown. Said varm passes through and is held by the arm V, as will be understood presently.
In operation the shaft N is driven toward l the observer, asindicated by the dart on the belt O, and whenJ the dump is at rest the pinionU must also revolve continually, therey transmittingl motion to the gear The latter, being ins mesh with the gear-drum S, will travel'within said drum without moving l the shaft N, since less force is used -in turning the arm V' about the shaft N than raising the dumping-frame' G. If now a wagon to be unloaded is placed Au on the platform with its front wheelson the ame G and the handlever 2 is moved to the right as viewed in the drawings, the result is to push the pin or rod 3 into thepath of said revolving arm V, as shown by dotted lines in Fig. 4. As the arm makes its circuit it meets the said pin 3 and stops. Since the yarm is brought to a stop and the gearWmust still revolve, due to pinion U, while still in mesh with the gear-drum S, said drum is thenmade to revolve in a direction opposite to that of the gear W and imparting revolution to the Worm, and consequently the lworm-wheel L. The shaft K is thus revolved jto turn the drums jJ and take up the cables I. In so doin the frame G rises out'of its seat in the atform, as shown in Fig. 3, and meets the w eel lodging between the. members thereof, so that the ence to the conveyer or drag 8, located be, hind it. When the wagon is raised to the desired height, it isstopped by throwing the lever 2 back to its initial position, thereby withdrawing the pin 3 and releasing thenrm V, which is again free to revolve as before, the wagon remaining in the raised position.
The movement ofthe lever 2 may be shifted either automatically or by hand, as desired. Erected on the platform is an upright 9, havinga rock-arm 11 thereon, one end of which is designed vto be met bythe frame G in its upward movement, the yother end having connection with the hand-lever 2 through a d rod 10, as shown in Fig. 1.
Evidently as theI said member G rises it will strike the arm 11, and the rod 10 will be drawn to move the pin 3 in `an opposite direction torelease the said arm-V; as described. "When desired to retu-rn the'wagon to itsnormal position, they lever 2 is moved still farther toward the left, with the result that the pin 7V of the fork 6- is entered between the teeth of the pinion U and gear W, thereby'stopping the revolution frame G. When .the-latter-memberv has reached its position -of rest, the lever 2 may be moved to Withdraw the pin' 7, or this may be ydone automatically by rovio ing a short rock-shaft 12 under the p atform, one enfi` having an arm 13, with which the frame G contacts when lowered, the other end having an upwardly-extending arm 1.4, connected by a pu l-rod -15 to Yan'extension of the lever 2 be 0W itsp'ivot Saidrod 15 is-slotted at-its endj'so that the lever maybe moved byhand i tempted toi S'o without being lhindered by said rod when again-throwing the mechanism in position to again raiseV the frame G. Y 'f A i *Infsho'win my invention I have not at- 'fvustrate any of the mechanism for'd'riving the' conveyer 8 or itsfelevatonas these' pafrtsfare too Well known torequire descriptionfV I-t is, -howe'venythe intention to operatethem from the'shaft N" Ain any good' manner,'so that 'they' will-'bein constant operation even though the wagon andv the rais'- ingfmechanis'mfmayjbe Aat 1rest;` yThe" object' in providing 'the-,gear members is that-theI` main poweridrivensha'ft N f may revolve ata uniform speedandgalso thatthe shaft Nwill revolve at'a uch slowerspeed in raisingthe loaded wagon in orderftofga'mI power by so diifg'f furthermore,l that when the `wagon is 'empty andreturningfto, its normal position thefmovementwill be fast, the shaft portion N- Yraming as yfastest the petition N.
