HOOD FOR PNEUMATIC STACKERS.
SPECIFICATION forming part of Letters Patent No. 660,591, datedoctober 30, 1900.
Application filed December 26, 1899. Serial No. 741,594. (No model.)
To all whom it may concern:
Be it known that we,ALLEN A. RUSSELL and HARLEY A. RUSSELL, citizens of the United States, residing at Indianapolis, in the county of Marion, and State of Indiana, have invent ed certain new and useful Improvements in Hoods for Pneumatic Stackers, of which the following is a specification.
This invention relates to improvements in the discharge-pipes of pneumatic straw-stackers, and has reference particularly to the construction and operation of the hood at the outer end of the pipe, by means of which the direction of the discharge is controlled.
This invention is an improvement on the hood shown and described in Patent No. 601,356, issued to A. A. and H. A. Russell March 29, 1898. 7
One object of this inventipn is to provide a very simple, inexpensive, and durable means of attaching the hood to the discharge-pipe in a revoluble manner to permit of free and easy turning of the discharge-opening to right or left to give the straw a lateral direction as discharged and, while providing a free-acting joint, to avoid the accumulation of heavy m aterial in its construction. This last matter of lightness is very important, because every ounce at the end of the long discharge-pipeis greatly multiplied by the long leverage and adds rapidly to the difficulty of handling the pipe and hood.
The further object of the invention is to provide a hood made out of a series of hinged and folding hollow spherical segments held open by a spring constructed to avoid inter-.
tracted or folded position; Fig. 3,a transverse section 011 the dotted line 3 3 of Fig. 2, and
to the rear.
Fig. 4c a longitudinal vertical central section of Fig. 1.
Like characters of reference indicate like parts throughout the several views of the drawings.
A represents the discharge-pipe, which will be made of a plurality of hollow cylindrical shown at a, Fig. 1.
A represents the last or outer section of the discharge-pipe. It will have the externallyprojected annular head a. near its outer end to form a guide and lock for the first section B of the hood. The section B has the externally-projected annular head 19, adapted to fit over the head a, permitting rotary adj ustment of the section B, but preventing its withdrawal or separation from the section A. To
enable the outer section to he fitted over the inner one, the former is split longitudinally on one side, enabling its walls to be spread, after which they are united by means of a two-part casting d d,the bases of each of which parts are preferably slotted to straddle the bead and follow the outside contour of the section B, to which they are riveted. Then they each have radial outwardly-projected plates,which contact witheach other and are bolted together after the beaded hood-section is in place on the beaded last section of the discharge-pipe. The bolt is represented at d, and d is a hole through the plates for the attachment of the cables 0 for rotating the hood. These cables are, as usual, two in number,
one passing to the right and the other to the left around to the top of the pipe and are rove through a slotted cast-iron block E, riveted to the top of the section A and having friction-pulleys e e to ease the turn of the cables The cables are carried down to the bottom of the pipe and are fastened to the drum of a Windlass or otherwise taken care of in the usual manner.
Running from the split side of section B in lines parallel with the bead and adja- ICO A portionof the bottom of this straightened,
wall is cut away. I
To the outer end of section B is secured a hollow spherical segment 1, which will preferably be riveted fast to said section B. Pivoted atf to segment 1 is a similar segment2. Pivoted to segment 2 is segment 3, and pivoted to segment 3 is segment 4:, any desired number of segments being introduced in like manner to form an adjustable elbow of the desired angle, enough being used, preferably, to cause the wall of the last segment opposite the chute to stand at least vertically, if not to incline inwardly, toward the chute at all ordinary angular elevations of the latter. This is to counteract the tendency of the straw to shoot off from the mouth of the hood at such an angle when discharged as to make a stack of too much obliquity on the far side from, the machine, the objection being that it permits animals to climb up easily and waste the straw. It will be noted that the pivotal points f for the several segments are at varying distances from the ends of the segments, the pivotal points of the middle segments being the greatest distance in from the ends of the segments. This is to cause the lower or end segments of the hood to draw in closer to the main pipe, thus making the front wall nearer vertical than would otherwise obtain. The last segment 9 is preferably wider than the rest and will be strengthened and stiffened by the semicircumferent-ial bead g. This section is more exposed to hard usage than any of the others and much annoyance has been occasioned by the mutilation of this last segment. This is I remedied by the beaded formation.
H represents springs (only the one on the near side is shown) made from strap-steel bent at the inner end it where attached to the hoodsection B in a manner to present the thin edge of the strap out. The front end of the spring has an eye, which is fastened to the post 2', attached to the segment 9. The spring is set and tempered to a curve, as shown in Fig. 1, tending normally to draw out or unfold the hinged segments. The curvature of the spring places it always away from the mouth of the chute along the side of the latter out-of reach of the discharging straw. To increase the efficiency of the springs action, we prefer to rivet the last three segments 7, 8, and 9 together by connecting them by means of a strap of metal j. To keep the springs H from opening the segments too far, we attach a chain J to the outer end of section B at b and to segment- 7 at 6 and then secure it at intermediate points to the intervening segments, as shown. At b and b are rings or eyelets, to b of which a cable 0 is fastened, which after passing through eyelet b is continued down to the base of the chute to a Windlass or other usual and suitable holding means. To keep the cable 0 from mixing and interfering with cables 0 and their block and pulleys, we throw the fixed bail m over them in the manner as clearly shown in the drawings.
Having thus fully described our invention, what we claim as new, and wish to secure by Letters Patent of the United States, is-
l. The combination with the discharge-pipe,
of a pneumatic stacker having an annular outwardly-projected bead near its outer end, of a hood-section mounted on said tube hav= ing. an externally-projected annular head to engage the head of the discharge-pipe, said hood-section'being split longitudinally on one side to allow the walls to be spread for as sembling and a two-part block each part hav ing a base fastened to the wall of thehoodsection, one on either side of the split and each base having an outwardly-projecting flange or plateand a bolt for uniting the plates, substantially as shown.
2. An adjustable hood for straw-stackers comprising a body-section split longitudinally on its under side and having its under walls partly cut away and straightened to plane surfaces and having a gore between the plane and adjacent cylindrical surfaces, a series of hollow spherical segments the first of which is secured to the body-section of the hood and each of the following segments to the segment immediately preceding it, some of said segments being pivotally attached to allow a folding adjustment thereof, the last segment having a longitudinal corrugation, said folding segments being connected by a flexible tie, all substantially as described and shown.
3. A hood for pneumatic straw-stackers having a body-section the inner end of which is cylindrical and the major outer portion of which has a semicylindrical top passing into sides which are plane surfaces, the bottom being open, a hollow spherical segment secured to the outer end of the body-section, a similar segment pivotally secured to it and a series of following segments each of which is secured by separate attachment to its adjacent segment some of them pivotally as shown, said pivotally-connected segments being also connected by a flexible tie as shown and a. pair of normally-curved strap-springs fastened at one end to one of the outer seg ments and at the other to the body-section of the hood, said springs being always above the mouth of the hood and tending to separate the segments, as and for the purposes specified.
4. In a hood for stackers, the combination with a body-section and a series of adjustable pivotally-secured sections, of a pair of strapsteel springs attached to one of the outermost pivoted sections at one end and to the bodysection at the other, said springs being normally curved to give the pivoted sections a maximum separation and being always above the mouth of the hood, substantially as described.
5. The combination with an inclined chute, of a hood in a plurality of sections, said sec tions being widest at their middles, pivots connecting the sections, the edge of each section near both of its ends being pivotally secured to the edge of the next adjacent section and not more than two sections being connected by the same pivot, said pivots from the middle to the outside sections being a gradually-lessening distance from the ends of the sections, substantially as described and speci fied.
