Specification of Letters Patent.

Patented Feb. 12, 1907.

Applica-mn filed March 15,1906. Serial N13-'306192.

To all, Liz/1,0m, it 1v1/(ty concern.:

Be it known that I, .Rasmus PnDnnsoN, a citizen of the United States, residing at Parkersburg, in the county of Butler and State of Iowa, have invented certain new and useful i and. I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its especial object to provi-de an improved device for loading manure into a \vagon;`a11d to the above ends i t consists of the novel devices and comhinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a plan view showing a wagon having my improved device. applied thereto. Fig. 2 is a side elevation of the parts shown in Fig. 1. Fig. 3 is a detail taken in section approximately on the line a x3 of Fig..1 showing particularly one of the fixed -guide-rails and coperating tripping devices, some parts being broken away and others being removed. Fig. 4 is a detail view in sideelevation,illus trating the action of one of the trip devices on the fork. Fig. 5 is a transverse section on the line ai of liig. 4. Figf is a view of the wagon and attachments, principally infront removed. Fig. 7 -is a detail view showing a modilied form of certain of the parts that are applied to the adjustable rail-sections of the device, and Fig. 8 is a view showing a wagon diagramma tically in rear elevation and showing a inoiiilied form ofmy improved device applied thereto.

Referring to the drawings, the numeral 1 i indicates the body, the numeral 2 the rear wheels, the numeral 3 the front wheels, the numeral 4 the pole: and the numeral 5 the seat of the wago11,wliieh wagon is preferably provided with a manure-spreading device of the ordinary or any suitable construction, the discharge-cylinder t3 only of which is shown. It may he here stated that my invention u ill usually he apilied to wagons le'vices, the primary purpose of my invention being,r tocfl'ect the rapid loading of such wagons and i to thereafter unload the wagons by means of the manure-spreading devices, which manurespreading devices, how ever, forni no part of my present invention.

Referring now to my improved attachmentfthe loading device, the numeral 7 indicates a pair of laterally-spacedguide-rails thatare rigidly supported one en each side of the wagon-box by means of vertical legs or posts 8, which, as shown, detachahly fit in socket-brackets 9, secured on the sides of said boX. Pivoted to therear end of each rail 7 is a vertically-adjustable rail 10, the lower end of which is preferably curved upward and rearward. These rails 10 are adapted to be set in various positions, either inclining downward or extending up ard or in horizontal direction, so as' to raise their curved ends upon the manure piles of different hei lits.

On t e extreme upturned ends' of the rails 10 are mounted guide-sheaves 11, and lower down on said rails'are guide-sheaves 12. At the pivotal joints betw een the rails 7 and 10,

but laterally oilset outward therefrom, are A guide-sheaves 13. On several of the railsupportilnr legs 8 are guide sheaves 14. Mounted 1n suitable bearings on top of and at the frontof the box 1 is a transverse shaft 15, which carries at its ends outward of the box and in line with the sheaves before noted driving sheaves or drums '16.

For picking up and' carrying the manure l provide va forkor toothed scoop 17, the tines of which are all rigidly secured to a transverse b ail 18, the trunnion portions of Vwhich have journaled thereonilanged truck-wheels 1Q, that are alapterl to run over rails 7 and 10. Also working loosely on each trunnion of the bail 18 are ilat non-rotary shoes 20, that stand in the same plane with the sheaves above noted. On each side of the wagon-box are operating-cables 21, the ends of which are attachedA to the corresponding shoes 2O on opposite sidcsrof the trunnions ol' the bail 18. These cables l1 are passed dver the guide-sheaves 1li, 11, 12, and 14 and are given several wiaps'around the corresponding driving-drums 16, so that they wi ll be positively mover.` when said drums are rotated. To take u the slack of the cables 2 l weighted floating s ihaves 22 are mounted thereon between two of the guidc-sheavcs14, as best shown in Fig. 2. The free ends of the rails 10 are preferably rovided with ground Wheels 23, which a apt the said rails to be ICO i ro

dragged over the gro indiwhen it is desired to: pick up scattered 'manureunder a forward movement of the wagon.

The shaft 15, which carries the driving--v drums 16, is adapted to be rotated intwo different ways*to wit, eitherby a handoperatezl lever or by horsepower. The hand lever driving mechanism, as shown, com` prises as follows: On one end of the shaft is' a sprocket 24, and mounted in suitable bearing-brackets 250 and 30a on the front end of the box 1 is a countenshaft 25, that is pro.

videi at one end, in line with the sprocket 24, with a sprocket 26, over which and said sprocket 24 runs a sprocket4chain. 27. The inner end of the shaft 25 terminates over the pole 4 ani is provided with a spur-pinion 2 8, that meshes with a spurfgear 29, mounted on sai bracketBO.. Theinumeral 3,1 indicates a latchlever which is pivoted to the bracket 30. in line'with the-axisof the gear 29 and is adapted to be llocked in any desired position to a notched segment 32, formed as part of' the bracket 30. Y The lever 31 carries a reversible driving-pawl that is adapted to y workupon the teeth of the wheel 2) to drive [the same 1n either of two directions, aeemd-` .ing-to the position. in which said pawl set.

By means of the lianddever 31 and eennections just described thetwo cables 21 may be driven in either direction, so to cause the fork to travel from a filling position at the freel en ls of the rails 1() to a dumping position on the rails -7 above the-.boxv 1 or from adumping position back to a filling position..

The horse-power driving device, as shown,

p is as follows: ligifily secured to one siie "of is pi'i-otel to a yokellike guide-head 40, that -mountegl to shle o n the rear portion of the pole, but is normally held rearward an.;

againstforwanl sliiing movement, as show n,

by a pin 41, that is insertel in a suitable seat in the pole. As shown, a metallic guidestrap 42, secured at its en is to the top of tht` pole 4, o'verlies the equalizing-beam 39 and limi tsits extreme sliding movements. Springs 43, attachedto theequalizing-beam 39 and to the rear enl of the pole, yielingly draws the saiil beam rearward... ,On the forward enlof the pole is a neck-yoke 44, that is provided with a neck-yoke ring 45, that adapts it to slide upon the pole. A long rod 46 underlying the pole connects the neck-yoke ring saaeoe to the head 40, and thus connects the neckyoke and equaliz'ing-beam, so that they will slide together on the pole. In Fig. 2 the neckyoke is shown as near the'end .of the pole; but

with the equdizingebeam secured in its rear- -most position said: neck-yoke should be far enough back on the polef so that under a for- 'ward .movement of the e utilizing-beam it will not be moved 0H from t the pole. l

different points along the fixed rails 7 are' pivoted fork-tripping arms 47,' which when raised will engage Withtrip-ngers 48,' that project in offset 'directions from the crank or swinging bodyportion of the bail 18 of the fork 17 As shown, there are three of these trip-arms 47 on each of the rails 7, and they' are arranged in transversely-ahmed pairs, so thatthe members'of a given pair. will act lsimultaneously on the two trip-fingers .48 ofthe said bail 18. The trip-arms 47 e forward endof V.that are most forward normally stand in p0- sition to engage the' said trip-fingers 48, those that are farther rearward normally stand in'inoperative positions below the lines of travel of said tripingers 48. These are connected by light rods 49, the forward ends of which are attached-to arms 50 of a rockshaft 51, thatis mounted-in suitable bearings on the upper forward portion of the wagonboX 1. 'T his rock-shaft 51 is provided with a footpiece 52, which when stepped upon will rock said shaft and raise .the rear and intermediate trip-arms 47 into operative positions. In lfig. 4 one of the trip-alms 47 is shown in an inoperative position by hill 'lines and in an operative osition by dotted lines. By reference to t is viewit will be seen that as the fork is moved forward and the trip-fingers 48 are thrown against the raised trip-arms 47 said fork will be tipped into a dumping position. (Shown by dotted lines at the left in Fig. 2.) It the o erator wishes to dump the load from the for at the rear portion of the box, he must raise the rear' trip-arms 47 (and incidentally the intermediate arms 47) before the fork reaches the said rear arms. lf he wishes to dump the laad at the intermediate portici` vof the box, he should wait until after the fork has passed the rear trip-arms 47 and then should raise the intermediate trip-arms 47 (and incidentally the rear arms 47.) The most forward trip-arms 47 normally stand in position to dump rthe load: but if for any reason it should be desirablev to carry the load farther toward the front the said forward trip-arms may be moved pivotally forward and downward into inoperative positions.

When the fork is moved down to the free ends of the rails 10, it may by a person si anding' in the vicinity thereof be caused to take up the lead by a forward rocking movement. As the fork is drawn over the points of pivv otal connection between the rails' and 10 IOO mit the free pivotal movements"4 of the rail' sections 10 from lowered to raised positions.

The usual way of lifting the loaded fork is te cause the horses to draw "tlie equalizingbeam 39 forward, and thereby through the flexible connect-ion 35'and intermediate cont described be sufficient to raise the loadedl fork onto the rails 7. In this way the horses are caused to perform the hardest part of the work in lifting the loaded'fork. Then by one or more reciprocating movements of the lever 231 the loaded fork may be moved over the rails 7 and dumped at the proper point, and thereafter by a reverse ratchet action of the said lever on the gear 29 the empty fork may be returned to a position for loading.

1n Fig. 2 at the right the fork is shown as turned into a reverse osition from that shown elsewhere in sai view. Otherwise stated, the forkis turne l with its tines projecting rearward. It 'may be desirable in some cases to set the fork in this position, so that it may be made to take a load from the side of the stack.

ln the modiiicatioii shown in Fig. 7 the guide-sheave 12 is not employed; but inlieu thereof the cable 21 is run through a curved tubular guide 53, secured to the curved free end of the rail i0.

In the modification shown in Fig. 8 the adjustable rail-sections 10 are shown as pivoted to the rails 7a, that extend transversely over the`top of the wagon-box, and are provided at'their central portions with trippingiiiigers' 47'. The said rails 'L are secured to connecting-supports 54, that are provided with flanged wheels 55, that run on the upper edges of the sides of the wagon-box, so that the entire device is adapted to be moved from front to rear of the box. AIn this in'- stance the cables 21, which may be opermaterial. In some instances it may bedesirable to remove the pivoted truck-rails ih after the wagon has been loaded7 and Athis may be done by removing the bolts that pivotally coimeet the rails 7 and 10. This be- Aing done, the fork may be removed, and the loose portions of the operating-cables 21 may be hung upon hooks 56 on the sides of the wagon-box. (Shown by dotted lines in Fig. 2.) p j What I claim is- 1. The combination with a wagon, of track'- rails extending therefrom to a position for loading, a"fo`rk or scoop'mounted to travel over said track-rails, from a position for illiing into a position for dumping into the waron-box, and trips located at dill'erent points and arranged to intercept said fork or scoop and-cause the same to dump its load into the wagon-box, substantially as described.

2. The combination with a wagon, of trachrails extending therefrom to a position for loading, a fork or scoop mounted to travel over said track-rails, from a position for filling into a position for dumpingA into the wagon-box, a cable attached to said fork or scoop at both ends, a draft-equalizing, beam mounted to slide on the wagon pole, and

driving connections between said equal- 'izing-beam and said Icable7 whereby the power of the-horses is rendered available for causing` the loaded fork or scoop to travel over said track-rails, and a device operative onsaid cable to impart return movements to said fork or scoop, substantially as described.

3. The combination with a wagon, of trackrails extending therefrom to a position for loading', a fork or scoop havingl a crank-like bail with wheels on its trunnions, which wheels run over said track-rails, a cable attached-to said fork, for causingl the same Lo travel oversaid,rails, and -trip-l ingers located along certain of the track-rails, in position to engage the crank portion of said bail. and cause said forli or .scoop to rock and dump ils` load into the wagon-box, substantially as described. j
