HOOD FOR STACKERS.

which shall be durable and substantial, at the same time being serviceable and simple in construction in order to withstand any use, to which it may be put. I To these endsmy invention comprises a hood which is preferably rotatably mounted on the discharge end ofthe conveyor, the hood being provided with a hinged. bill or extension which forms a continuation of the body of the hood and or guide adapted to enlarge or constrict the discl1argeopening of thehood. Both the apron and bill are controlled and adjusted in the discharge a suitable manner, as will he hereinafter set forth.

To all whom it mu, concern: I Be it known that I, ABRAHAM LUKE, a citizen of the United States of America, residin the county of Elkhart' and State of Indiana, have invented certain new and useful Improvements in. Hoods for cation.

My invention relates to an improvement in hoods for stackers, and more particularly to that class of stackers wherein the straw a cornhusker means of pneumatic pressure, end of thepipe being provided with a hood g therefrom to form a suitable novel features of construction and combinastack. tion of parts, such as will be more fully de- The objects of my invention are to provide scribed hereinafter, and particularly pointed a'hood of this character which can be so maout in. the claims.

in the accompanying drawings, Figure 1 is a view in side elevation of my improved hood, showing the bill in its lowered )osition. Fig. 2 is a similar view showing the ill in its extreme raised position. Fig. 3-is a detail view of the track on which is supported the hood.

It i Fig. 2, looking in the direction of thearrow. is well known that a stack which iscom- ,Aindicates the conveyer pipe, which may menced from a point beneath and rearward be of the usual telescoping variety and is much easierto handle and to connected at its lower end to a threshingmachine, for instance, in the usual manner,

the stramor other material to be stacked being fed into-the pipe at its lower or receiving end, a fan. or air-pump also communicating will be guided thereby and. directedto apoint rearward of the veyer-pipe and on a' line nearly parallel thereorder to commence the foundation of the stack asfar back as possible to enable the Another and scarcely less important ob l ject is the provision'of a hood so constructed ous air-current during the progress of the so as to avoid any choking of the material inv the hood. My improved hood causes the straw to flow out evenly and continuously and prevents the dropping of straw in bunches, which is a dis l is advantage heretofore encountered.

A still-further object is the provision of a hood capable of rotation, by means of which much as it forms no part of my invention, is

not shown. 7 v

The upperhend of the conveyor-pipe A provided with a circumferential annular track 1, secured thereto and.. projecting flange-like therearound; The lower end is formed into a without the upper end I provided with brackets l of W pipe 2, telescoping of the conveyer, and of a circle,.d'epend- 3 3, inthe free ends only upon .the amount of a ir r'essu re, high are journaled the grooved rollers 4, thus enabhng'the stream'to be a solutely' whichtake or ride upon controlled and' placed wherever desired. I

With 'an approximately rectangular enlargement also having an apron My invention further consists incertain with the conveyer in order to force the mate-. rial therethrough. This construction, inashood B at its the'track l and serve r-s permitting the rotaadvance of the pipe 2 the. hoodis providedv I .5, cut entirely away on one sideon. an A (Ether ob ects are theprovision of a hood l'lncline extending transversely tothe area of.

the hood to t'orm' a discharge-opening, and the extreme end of the body portion of the hood is partially closed by means of the curved wall 6, extending to a point approxi- 5 Inately half-wayacross the area of the hood. The side edges of the'cut-away portion'of the hoodiorrn'obtuse angles, as shown in the dotted and full lines in Fig.2.-

An apron or guide 7 is hinged at its rear end m to therear edge of the cut-away portion or discharge opening inthe hood, .:.the apron comprising a plate of a size and shape substantially er uIvalen-t to the area of the a erture from t e meeting of theinclined ed ges r 5 7 7 'th ereof to the reaif 'edge, the plate being I provided with. checks 8 of gradually-increas mg ,width, extending along the side edges of;

the plate, and adapted to 'overlap'the body portion oft he hood. j The outer end. of the apron is open and unobstructed,

and a' space. is let t between the outerend of the apron and the lower edge of the curved wall forf dis charging. material under high pressure.

Pivotally secured to the lower end of the curved wall .6 is the bill orextension 9, which in sha )e is a continuation of the curved outer end oi the hood and is -provided with the llangeslO 10 to assist in guiding the straw or other material discharged from the conveyor.

, Guide bars 1313, slightly curved 'in' the arc o'l a'circle oppo'siteto thearc described by the outer end of t'hc'bill 9, are secured to-the side walls 1'1 11- of the outer end of the hood, and the rear-edges of the flanges 10-10 are 3% provided with guides l2 12 of approximate L shape, which are received between the bars 13 andthe walls ll"1 l. VVhen' the bill is in its lowered position, the rear ends of itsflanges overla' the outer. ends of the walls o 11 11 and assist t 1.0 guides in properly retain- ,fing the'l'guide. in position during'its movements,.as Well as'controllin'g the direction of movement of the-straw and bracing, the bill against lateral strain in the same manner 5 that the cheeks 8 8 brace the apron or guide to control'and confine. thestrcam of material; The outer rearwardly-projecting ends ofthei L sha'pc'd guides are adapted to en'-.

withgand beneath the 'con-veyeror toward the thresher.- The' great 'purposeof the checked apron is to confine the stream-of straw and glide it against the curved wall of the hood at the greatest possibletangent, and if the apron were not employed the stream of material would strike,squar'ely against the outer downwardcurveof the wall andfizhoke the conveyor or-else fall in bunches. Of-course when it is desired to 4 drive thematerial straight out-of the con- 8o veyer the apron is dropped downand-"the bill raised out of the way, so that while the cheeks confine the stream against spreading laterally'there is nothing to impede or break its-force. e 85 Secured exteriorlyofthe cur-veelwall o of the hoodjs a bracket 15', to the upper end of 1 whichis attacheda spr'ing 16, the op osite end of which springis fastened to the bi l,'and this spring, togethenwith .the force oi'the-ai rressure, normallytends to raise the bill.

rackets 1-7, carried by. the stationary p'ortion of the hood, have pulleys 18 journaled therein, over which pulleys run the split ends of a cable 19, the ends-of such cable being secured to' the eyes 20., fastened-to the lower rear edges of the flanges 10, the cable extending to, the'thresher or other machine with which the conveyer is used for the urpose ofcontrolling theactuation of the bil and the apron by spring 1 6' and the airpressi'1rean( l to close the bill and raisethegapron against such. pressure, It will also be observed that wires 21 extend from th forward end ofthe bill, on each side thereof, to tlieeyelets 20in order to distribute the'strain caused: by pull on the cable 19. p

II'1 order to rotate the hood on the conveyer to cause the discharge of"m aterial to one side or the other of the conveyer, 1 secure the ends of asplit cable 2210 points on opposite'sides of'the pipe 2 ofithe' hood, the split ends passing over-pulleys 2 3, suitably .journaled in brackets 24 011 the pipe 2, the] opposite end of the cable being led'toapoint f within convenient reach of the operator, whereby he can by pulling in one direction or the other rotate the hood.

From the foregoingit will be seen that I have inventeda'simple, neat, and inexpen 12o "sive deviccof'the nature set forth. I v

, The spring 16 serves to retain the bill in open position normally, and yet maybe; overcome by Lpulling; on the cable .19, which when easeup will slacken to permit the air- 5 pressure,'together with the tension of the 1' during, to r aiselthe hood. 1 Furthermore, the lfbill-caribeheldin-an' position desired inter v mediate its opposite limits of movement. As

the bill is. raised the apron is automatically 13o from the decrease the size of the opening. I

- portion bill pivotally lowered to open or enlarge the dischargeaperture of the hood and allow the material to have a free, sweep The discharge when, in this positionis not ragged, since the walls li and the-flanges 10; together with the cheeks 8, operate. to confine the straw or other material against lateral spreading as it is discharged from the hood and to enable the'operator to place the-material where desired.

It is evident that many changes might be made in the form and arrangement of the several parts described without departing s irit and scope of my invention, and hence l do not wish to limit myself to the exact construction herein set forth; but, fully disclosed my invention,
