JOHN I-I. -ELwARD, OF PEORIA, ILLINOIS. e
P N EUMATIC STACKER.
SPECIFICATION forming part of Letters Patent No. 688,400, dated December 10, iobi. Application filed January 5,' 1893. Serial No. 45 7.328. (No model.)
To' all whom, it may concern:
Be it known that I, JOHN H. ELWARD, a citizen of the United States,residing at Peoria, in the county of Peoriaand State of Illinois, have invented certain new and useful Improvements inPneumatic Stackers, of which the following is a specification, reference being had therein' to the accompanying drawings.
Figure 1 is a side elevation ot' a straw-stacking mechanism embodying myimprovements. Fig. 2 is a top plan view. Fig. 3 is a vertical central longitudinal section on the line x of Fig. 2. Figs. 4 to 15 show details. Fig. 16 is a side View of a modification. Fig. 17 is a vertical section of a part thereof. Fig. 18 is a section similar to that in Fig. 17, showinganother of the adjustments ofthe spout or chute; and Fig. 19 is a view ofthe upperend of the chute or spout,villustrating the adjustments of the deflector.
In the drawings I have shown a portion of a threshing-machine sufficient to illustrate the manner of,employing my mechanism in connection therewith, the elevator or stacker herein provided being adapted for use with any of several styles of threshing-machines.
In order to provide a strong and durable machine, I provide for the elevator or stacker a supporting-frame and transporting-wheels, which are separate from and independent of the frame and the wheels .which carry the parts of the thresher proper.
A A indicate the sills and cross-girths of such a frame, it being mounted upon front and rear wheels ct o'. Uprights A2 of suitable number are secured to the bottom frame A A',
A and at the top they carry a horizontal framework having the longitudinal parts Asand the cross-bars A4.
The frame and wheels constitute avehicle separate from the thresher, and by means of a pole or draft devices at A5 this vehicle can be hitched to the engine sometimes employed for transporting, or horses can be employed, as desired.
The elevator or stacker comprises as its essential elements an initial receptacle, an airblast mechanism, and the upwardly-extended chute. y i
`'Ihehthresher at B has an exit at b for the To receive the said chaff into the initial receptacle of the stacking mechanism. At d there is an opening or mouth, which can be brought close-to the end of the said carrier b2. Thus both the straw and the chaff or fine stuff can be thoroughly collected from the thresher, passages foreach of them being provided in which they can travel on substantially the lines along which they normally escape from -the thr'esher.
At the bottom and front end of the stackervehicle I place the ejector-fan E and the fancasing e, there being a throat at e', through which the jets of wind pass upward through the chute C, this throat being below the line at which the chaff escapes from the threshershoe. The currents of air are of such strength as to propel the chaff upward, andA when they 'reach the straw which has 'been introduced through the orice at b they also force it, togetherwith the chaff, to a considerable distance.
To direct the material which is carried upward and backward by the'wind to the places where it is desired `to deposit it, I combine with the parts above described an adjustable mechanism for guiding the straw and the aircurrents, as follows: The' initial receptacle terminates in acircularportion at d. Around the edge of this part there is mounted a ring F, it being formed with the Vertical partf and a horizonal langef, the horizontal flange f having a series of gear-teeth f2. The ring F thus forms what may be termed a rotary base for the straw-guiding mechanism, and to support said base the horizontal flange f is placed between antifriction-rolls fsf, some below it and some'above. To the ring F,
above described, there is secured a hood Gr, preferably formed of sheet-iron, having the rounded front part g and the backwardlyex IOO tending walls g' g2, the parts g2 being at the sides and the part g being curved so as to form substantially the part of a cylinder. To this hood G is fitted the lower part H of the tubular duct or delivery-trunk. It is formed with a top h, the side pieces h', and the bottom h2. It is flared or expanded somewhat at the inner end, so as to surround the inner parts g' g2 of the hood G. In the construction shown in Figs. l4 to 3 the bottom plate h2 is extended somewhat and at the inner end is formed of elastic material, by which elastic part the spout H is secured to the hood G or to the rotary base. When the parts are constructed and arranged in this way, tiexure is provided, so that the spout H can be readily adjusted vertically to any desired position. It will be noticed that during such adjustments ot the duct -section H the portions thereot` in contact with or surrounding the walls g' g2 of the hood or base section and not secured thereto will be moved on curved lines longitudinally of said base-section-that is, the said portions of the lower orinner end of said duct-section H are arranged to vibrate relatively to or move toward and from the rotary base or support when the vertical position of its outer end is varied. The delivery trunks or ducts are ordinarily made of sheetsteel, as is common, in which case there is suicient tlexure and resiliency, or, as above stated, a supplemental piece of elastic metal can be applied for these purposes. The edge ha lits snugly to the above-described curved part g', and the attachment of the section H is effected in such way that as the outer end is depressed or raised said edge h3 shall remain in contact with said wall g' of the inner or base section G of the delivery trunk or duct.
I indicates an outer duet-section fitted to the outer end of the part H and adapted to be moved out or in rectilineally in yrelation thereto. Preferably the two sections H and I are telescopically connected, so that the section I can be drawn down over the section H to make the apparatus compact when it is being transported. The mechanism for effecting this longitudinal movement of the section I comprises the rack-bar K, secured to it, and the pinion K', mounted in bearings at k on the section H. The end of the outer section I of the spout is provided with an adjustable guide or deflecting-apron J, adapted to direct the straw in any line desired. To adjust this, use is made of a bar J', extended back to points where it will be accessible and having combined with it means for locking it in any desired position. In the construction shown the bar J' is provided on its upper surface at an intermediate point of its length with a series of teeth or projections j. This toothed or corrugated portion of the bar J extends through a guide-clip jz, mounted on the portion H of the stacker-spout, and within said clip is formed one or more lugs or stops ja, adapted to engage with the said teeth j and hold the bar J stationary andY retain the adjustable guide or defleotor J in the desired position. A leaf-springJ2 or equivalent device is arranged within the clipj2 beneath the bar J' and serves to keep the teeth on said bar in engagementwith the pin or stop js. The defiecting-apron is illustrated as being supported at a. distance from the end of the delivery trunk or duct and is carried by arms or bearers j, to which it is pivoted. By thus arranging the deflecting-apron or guide it can be held in the position indicated in Fig. l entirely out of contact with and at a distance from the mouth of the stacker trunk or duct so that the air escaping therefrom is allowed to dissipate in all directions, or, as shown in dotted lines in Fig. 19, the deflector can be adjusted to contact with and form a continuation or extension of the upper wall of the delivery-truuk-that is, the straw and chaff are readily guided into the proper paths and deposited at the desired points by adjusting the detlector.
To raise and lower the delivery trunk or duct, use is made of ropes or cords L. They are secured at their outer ends to the spoutsection I (preferably at or near the middle thereof longitudinally) and then extend up over sheaves Z' and down to drums or spools m on a winding-shaft M, which is mounted behind the hood or base duct section G and is provided with cranks at n' for winding it and pawls n2 for locking it. The sheaves or pulleys Z' are mounted in the upper end of braces N. These are formed of two or more sections n n', so connected as to provide for extension, and each brace as a whole is pivoted at 71,2 to the aforesaid rin g or rotary base.
To permit of the longitudinal extension of the braces N, these braces are made in two sections wand it', as before stated. The parts n ot' overlap, the part nbeing preferably slotted and the part n' being tongued to tit the slot. Metallic loops p can be placed around the overlapping parts, so as to hold them firmly in proper relation to each other and yet allowlongitudinalmovement. Asshown,the part 'n' is moved upward by a rope Q, which has its end fastened to the lower end of the tongue p', and passes thence upward to a sheave q on the loop p and thence down to a winding-reel Q', mounted on the part n and having a crank q2 and a locking-ratchet qs.
To hold each brace N at the desired angle of inclination to the plane of the ring F, I use bars O, which are pivotally connected to the ring and are connected to the brace-bar N by means of a nut O' and a screw-rod O2, mounted in bearings at o' o2 on the part fn, the part O' having an extension o3, to which the supporting-link'O is pivoted. The screw O2 can be rotated, as by applying a wrench at o', and the nut can be thereby moved up or down, as desired.
As it is desirable to deposit the straw not only at points in the vertical central longitudinal plane of the machine, but also at ICO ' ess,4oo ,53
points in planes at the sides thereof in order to distribute the stack over a ground area as large as possible, and is also desirable to constantly change the point of deposit, I combine with the mechanism'above described means for automatically oscillating the stacker tru nk or duct. R is a pinion meshing with `the above-describedteeth f2 on the ring F of the rotary base or support for the delivery-duct, it being carried by-a shaft R', mounted in a bearing at r, secured to the top frame-bar A3. This shaft has also two beveled wheels S S', each adapted to engage with a beveled pinion S2, mounted on a vertical shaft s, said shafthaving a belt-wheel s', driven by a belt S3, extending to anysuitable pulley on the thresher. The wheels S S' are loose upon the shaft R' and are continuously rotated in opposite directions. 1 T is aclutch feathered to the shaftand adapted to engage said wheels alternately with the shaft. The clutch is automatically shifted, as follows: T is a belllever `pivoted at t. T2 is a vibrating lever having a weight T3 to carry it past its center and temporarily hold it. This lever is preferably pivoted so as to vibrate in a plane which is tangent to the circle of rotation of the ring F and is connected with the lever T', as shown. l Said ring or some part carried vss thereby is provided with trip-pins 3154, and lever T2 o r a part connected with it lies in the path oftheir rotation. `As shown, this lever T2'is connected by a link Tt to a lever T5, which latter can be impinged on by said4 trippins t4. When the pin t3 'reaches said lever T5, it throws it andthe lever T2 over, so as to reverse the clutch, and thereupon the shaft R', is reversed and also the ring F. This movement of the latter continues' until the pin t4 reaches lever T5, whereupon the latter is thrown back and shaft R and ring F are again reversed. In this way the stacker- Vchu-te will be oscillated, so that the straw can be delivered'from its outer'end over a large areal.
The manner of operating the above describedmachine will be readily understood. After the thresher B has been properly placed the stacker-vehicle is brought into the requisite position and adj usted so that the vopening behind the thresher-ch ute shall register with the entrance c in the chad-.receiver C and so that the straw-exit at b shall register with the entrance-orifice d in the stacker. belt S2 is properly connected. The outer ductsection I is extended to' the desired point. The proper angle of inclination for the braces N is provided by suitably adjust-ing the nuts The 4duct-sections H I areadjusted to the proper inclination, and the fan E is connected bya belt to its driving-pulley. -As
higher the positions of the parts H, I, and J are The varied by the adjusting devices at M, O', and
Q, and the position of the deflect-er is varied In this case there is a iexible canvas or leather joining device, (shown at U,) the ends of which can be fastened to the hood and to the said spout or duct section H. By the employment of this flexible covering device I avoid thenecessity of an air-tight union between the vertically-adj ustable portion of the delivery duct or trunk and the base section or hood G, although they should be fitted as `closely together as is practicable without linterfering with the desired play laterally and vertically of,l the outer end of the chute or spout. be seen that in a full-sized mechanism the lower or inner end of the chute or duct section H can be .left sufficiently loose in the hood to permit of the required movements of ,its delivery end, and at the same timethe flexible cover U insures that the air must escape through the chute H, so that the straw, chaff, &c., will not pass between the overlapping surfaces. y
. I am aware of the fact that mechanisms have been made orproposed comprising tubes onel sliding upon another, in combination with means for effecting such sliding, these means including sometimes a rack and apinion', as shown in the patent, No. 319,552,10 I. Brokaw' and W. Butler, and sometimes a rope and sheaves, as shown in the patent, No. 405,331, to L. Smith, and of -course I do not wish to be understood as broadly claimingv either of these old mechanisms for all such purposes; but I believe myself to be the first to have constructed a pneumatic stacker for th reshing-machines in which the' air trunk or` chute could be varied at any time,` even when in full operation, and by devices, such as aforesaid, accessible to the operator when standing near the inner or lower-end of the duct, so that the material could be delivered at points gradually farther from the thresher By examining Figs. 17 and y18 it willl IOO without altering the elevation of the chute and in which the vertical position of the delivery end of the chute could be varied at any time, so that the straw could not only be carried first nearer and then farthery from the thresher, but could also be gradually piled higher and higher, as well as taken lfarther and farther out, and while I have above given a specific description of thelillustrated devices in order that the features of invention can be fully understood I wish it to bev also distinctly understood that I do not limit myself to all of said specific matters, for there can be many modifications as concernsthe details of construction -and arrangement without 'departing from the invention.
