ELEVATOR AND DUMP.

SPECIFICATION forming part of Letters Patent No. 744,767, dated November 24, 1903.

r Application filed June 29,1903. Serial No. 163.631. (No model.)

To all 'whom itma y concern:

Be it known that I, JOHN .W. KING, a citizen of the United States, residing at Waitsburg, in the county of Lincoln and State of Washington, have invented a new and useful I Elevator and Dump,'of which the following is a specification. v

This invention relates to that class of dea suitable point of elevation and theredumping the same; and it has for its object to pro .vide a device of this class which shall be esmachine and there dumped.

A further object of my invention is to construct a device of this class in such a manner as to be extremely simple, inexpensive, and: easily operatedand possessed of a great range.

1 points by suitable braces 15 and near their With these ends in view the invention consists in the improved construction, arrange ment, and combination of parts, which will; be hereinafter fully described, 'and particu-I ries a sprocket-Wheel19, the outer face of of utility.

tor and dump with the carrier elevated and with dotted lines illustrating the dumped po- Fig. 2 is a top plan view. Fig. 3 is laterally-extending arm or bell-crank 24, said sition. a bottom plan view ofthe carrier.

Corresponding parts in the several figures; are indicated by similar numerals of refer-Q above their intersections with'the cross-pieces 3 and 4 uprights 7, upon which frame- bars 8 and 8 are mounted abo ve and parallel to the sills 1 and'6 and ofa length'about-equal to the respective lengths" of said -sills. The frame-bars 8, uprights 7, sillsl6, and as much of the sill 1 as is included between the front and rear uprights 7 thus combine to constiextended between the uprights 9.

tute an auxiliary framein which a portion of the operating mechanism of my improved elevating and dumping device is mounted.

Suitably supported upon sills 1 and 2 near the rear ends of said sills are a pair of uprights 9,, connected at their upper ends by a cap-beam 10. The track-bars 11 of the device are pivotally connected with the sills 1 and 2 at the front ends of the latter and are The latter are provided with a plurality of inclined notches 12, in which a cross-bar or supporting-rod 13 may be adj ustably supported, said cross-bar serving as a support for the inclined track-bars 1 1,'which latter may thus, by adjusting'the position of the bar 13, be adjusted at an y desired inclination within the capacity of the device. The track-bars'll are provided with flanges 14 for the purpose of guiding the carrier, to be hereinafter described, and said track bars are" connected at intermediate upper ends by a transverse brace 16.

V The frame-bars 8 support near their rear ends a revoluble shaft 17, carrying a drum 18. A projecting end of said shaft also carwhich is provided with ratohets 20, forming a clutch member adapted to cooperate with a clutch member 21, mounted slidably upon the shaft 17, and having an annular groove 22, engaged by a forked lever 23, having a lever, comprising the members 23 and 24, being suitably fulcrumed tothe frame of the machine. Pivotallyconnected with the lever-arm 24 is an operating-rod 25, which extends through a suitably-disposed guide 26 in a forward direction to'apoint at which it may be conveniently manipulated by the op erator to throw the clutch members 20 and 21 into or out of engagement. It is obvious that the combined clutch member and sprocket wheel is normally loose upon the shaft 17, with which it may be operatively connected by means of the slidable clutch member 21, the latter being connected rotatively with the shaft 17 by means of a fin or spline or in any other suitable well-known manner. 4

27 designates a shaft which is supported revolubly in boxes 28 upon the under sides of the frame-bars S and 8, and said shaft carries a ratchet-wheel 29 and a sprocket-wheel 30, which latter is connected by a chain 31 with the sprocket-wheel 19 upon the shaft 17. Adjacent to the sides of the ratchet-wheel 29 are a pair of arms 32, which are mounted pivotally upon the shaft 27, and each of these arms carries a pawl 33, engaging the ratchetface of the wheel 29. 4 These pawls may be weighted orspring-actuated in order that they may be held operatively in engagement with the ratchet-wheel.

34 designates an operating-lever fulcrumed at 35, and 36 36 are a pair of connecting-rods pivotally connected with the operating-lever 34, equidistantly from and at opposite sides of the fulcrum 35, the outer ends of said conmeeting-rods being pivotally connected with the pawl-carrying arms 32.

A wheeled carrier 37, the detailed construction of which will be presently more fully described, is adapted to run upon the inclined trackbars 11, connected by the brace 16, whichlattersupportsaguiding-pnlley 38,0ver which passes the hoisting-rope 39, one end of which is made fast to the carrier 37 and the opposite end of which is connected with the drum 18.

It will be seen that when the operating-lever 34 is manipulated the pawl carrying arms 32 will be alternately reciprocated in opposite directions, thus imparting to the ratchet-wheel upon the shaft 27 a rotary motion, as will be readily understood, one of the pawls33 slipping over the teeth of the ratchet, while the other pawl simultaneouslypropels the ratchet-wheel in the proper direction. Rotary motionisthusimpartedtothesprocketwheel 30, from whence it is transmitted by the chain 31 to the sprocket-wheel 19, which is supposed to be in operative engagement with the clutch member 21. The shaft 17, carrying the drum 18, being thus revolved, the hoisting-rope will be wound upon the drum, thus causing the carrier 37 to travel in an upward direction upon the inclined track, which, as previously described, has been adjusted at the desired inclination. After the carrier has reached the proper elevation and been tripped, as will be hereinafter described, the operating-rod 26 is manipulated by the operator to disengage the clutch members 20 and 21, when the drum-carrying shaft will be rotated to unwind the hoisting-rope from the drum by the descent of the carrier, which is accomplished by the weight of the latter.

The carrier 37 may be described as consisting of suitably spaced and connected side pieces 40, having wheels 41 and provided with a cross-piece 42, pivotally mounted between the side pieces of said carrier and supporting a dumping-board 43. It should be observed that the pivoted cross piece 42 should be disposed comparatively near the lower end of the carrier-frame, so that approximately two-thirds of the dumping-board shall be disposed above the pivotal point in order that the weight of material placed upon said dumping-board shall be sufficient to tilt the latter at the point of discharge. The dumping-board is provided at its lower end with a cleat 44, affording a rest for the material placed thereon, such as a sack of grain, and it has a downwardly-extending slotted catch 45, adapted to be engaged bya spring-actuated latch 46, which is mounted upon the under side of the carrier-frame. downward-extending spur 47, which is adapted to be engaged bya trip 48, suitably disposed upon one of theinclined track-beams 11. The operation of this part of my invention will be readily understood. When the carrier is at the lower end of the track, the material to be elevated, which, as stated, is usually in the form of grain in sacks, is placed thereon, displacement being prevented by the cleats 44. The carrier is then elevated upon the track in the manner described until it reaches the upper end or discharge-point, where the spur 47 of the latch 46 is engaged by the trip 48, thereby disengaging the latch from they catch 45, and thus causing the dumping-board to be tilted by reason of the excess of weight above the pivotal point of the dumping-board. As soon as the latter is relieved of its weight the rod 26 is manipulated by the operator to disengage the clutch members 20 and 21, thus permitting the carrier to descend by its own weight, the latch mechanism becoming automatically locked when the dumping-board is restored to its normal position by its passage over the cross bar or brace 16.

I desire it to be understood that while I- have in the foregoing described a simple and preferred construction of my improved elevating and dumping devicel do not necessarily limit myself with regard to the structural details herein set forth, but reserve the right to any changes, alterations, and modifications which may be resorted to without departing from the spirit or scope of my invention and without sacrificing the utility of the same.
