SECTIONAL A ND ADJUSTABLE DlSCHARGE-SPOUT.

SPECIFICATION forming part of Letters Patent No. 744,408, dated November 17, 1903.

Application filed June 19, 1903. Serial No. 162,145. (No model.)

To all whom it may concern;-

Be it known that 1, AUGUST ROSENTHAL, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a newand useful Improvementin Sectional and Adjustable Discharge-Spouts, of which the followingis a description, reference being had to the accompanying drawings,-which are a part of this specification.

My invention has relation to improvements in sectional and adjustable discharge-spouts more especially intended, although not necessarily, for use in connection with corn husking and shredding machines, to serve as a passage-way for the travel of the cut and shredded husks and stalks to the place of deposit. It is, however, equally adaptable for use in connection with straw-cutting machines, threshing-machines, various forms of feed-cutting machines, and, in fact, in connection with a variety of different machines such, for instance,'in conjunction with elevators, to serve as grain-spouts therefor.

In many forms of machines of the character above referred to the spouts are continuous and the terminal portions project at more or less abrupt angles. In consequence the cut or other material fed through the spout is impeded by and is lodged at the angle, causing a clogging at such point, and hence nocessitating frequent cleaning. As these long continuous spouts are difficult to clean, it is of course obvious that a construction is desirable which avoids the objections pointed out, and hence various forms of adjustable and sectional spouts have been devised with provision for changing the curvature thereof,

so as to avoid the obj ectionable abrupt angles.

A further object of my invention is to pro-.

vide a hood at the discharge end of the spout, said hood having means whereby it can be adjusted independently of the spout, so as to direct the discharge either up or down or to the right or left.

With the above primary and other incidental objects in View the invention consists of the devices and parts or their equivalents, as hereinafter set forth.

In the accompanying drawings, Figure 1 is an elevation-0f a spout constructed in accordance with my invention, showing the sections adjusted to a curved form. Fig. 2 is a vertiindicates the lower spout-section, which projects rigidly from a casing or from the drum from which the material is forced. In the application of my invention to a corn husking and shredding machine this spout-section usuallyprojects from a fan-drum, and the cut and shredded material is forced into the spout by the action of a fan. The othersuccessive spout-sections shown in the drawings are indicated, respectively, by the numerals 7, 8, 9, 10, and 11. Of course as manyof these spout-sections may be employed as desired, depending upon the length it is'desired to have the spout. Each spout-section is slightly less in diameter than the next succeeding section and telescopes slightly at its forward end into the rear end of said succeeding section and is pivotally connected thereto by means of lateral trunnions 12 12.

It is desirable that the lowermost adjust able spout-section 7 should be connected to the fixed section 6 by means of a swivel'joint, so that the entire spout may be swung around in order to regulate the position of the discharge end. In the accompanying drawings I illustrate the preferred form of swivel connection. Referring thereto, the numeral 13 indicates an angleband which is secured fast around the upper end of fixed section 6, one flange of said bandbeing uppermost. Loosely surrounding band 13 is a similar band 14, having its flange uppermost and beneath the flange or band 13. Band 14 is provided with projecting lugs 15 15, and at an opposite point of its circumference the band is provided with two other lugs or cars 16 16, which are farther apart than the lugs 15. Fitting around the lower end of a short tube 17 and fast thereto is a flat band 18, which is provided with two lugs or ears 19 19, adjacent to and on the inside of the lugs 16. A bolt 20 connects the sets of lugs 16 and 19. x The band 18 at an opposite point of its circumference is provided with a projecting ear 21, which lies between the lugs 15. A transverse bolt 22 connects the lugs 16 and the car 21. Engaging a threaded opening in the band 14 is a thumb-screw 23, the inner end thereof being adapted to be turned tightly against the inner band 13. When the screw is loosened, the spout is free to turn at the swiveljoint, so that the spout-sections may be swung by hand to the desired position, and after being so swung the screw can be tightened, so as to hold the spout at such position.

Two bars 24 and 25, respectively, are hinged together at their inner meeting ends, as indicated by the numeral 26. The rear end of bar 24 has two straps 27 27 projecting therefrom, and the lower ends of these straps are pivoted on the bolt 20. The forward end of bar 25 is hinged to one of the spout-sectionssay the section 1 lby a hinged joint 28. Connected to one of the bars, preferably the bar 25, is a rope, cable, or other suitable operating device 29. rope or cable will tend to straighten out the bars 24 and 25, and this action of the bars will necessarily straighten out the spout, each spout-section turningon its pivot. In order to adjust the spout to the curved form illustrated in the drawings, an initial upward or lifting force is exerted thereon, and the spout will then by reason of its own weight assume the curved form illustrated in Fig. 1, the amount of curvature being limited by contact of the rear end of bar 25 with the under side of the spout-section immediately thereabove.

In the use of the invention the thumbscrew 23 is first loosened, and this permits the spout to be turned so as to bring its forward discharge end in position to discharge at the proper place. The thumb-screw is next tightened, and then the spout is given the proper curvature in the manner hereinbefore pointed out.

It will be seen from the above description that I provide a simple and easily-operated construction in which there are no sharp bends or angles to impede the material traveling through the spout, and at the same time provision is made for readily varying, adjusting, and holding the spout in desired positions to discharge at the proper point.

It will be noticed that the swivel-joint not only enables the spout to be turned so as to direct the discharge to the proper point, but said swivel-joint is also of such construction as to form a hinge which may be useful in turning the spout back over the machine, so that the machine when the Work is completed It is obvious that a pull on this.

at one point may be readily removed to another location. To accomplish the swinging back of the spout, all that is necessary to be done is to turn the spout around on its swivel so that said spout will be over the top of the machine. The spout may then be turned downwardly in a compact position over the machine, and this is done by taking out bolt 22 and permitting the entire spout to turn downwardly on the pivot 20.

The lower outer band 1 1 of the swivel is preferably of two similar half-sections, and the bolt 20 serves to connect the two lugs 16, while a short bolt 30 connects the opposite lugs 15.

I prefer to employ in connection with the discharge end of the spout a hood provided with independent means for adjusting the direction of the discharge. This hood consists of two main sections 31 and 32, respectively, the end of the former telescoping slightlyinto the end of the latter and a short tube-section 33 telescoping slightly into the end section 31 and slightly over the end of the terminal section 11 of the spout proper. Each of the sections of the hood is pivotally connected by means of the trunnions 12. Section 32 of the hood has a projection 34 extendingtherefrom, and the short tube-section 33 has a similar projection 35 extending therefrom, the two projections being connected by a coiled spring 36. The rear end of short tube-section 33 is also formed or provided with an annular rib or rim 37, over which is adapted to engage the rounded hooked ends of a plurality of metallic straps 38, secured to the spout-section 11. Connected to opposite sides of the terminal hood-section 32 are the ends of ropes or cables 39. These ropes or cables are extended rearwardlyand through guides 40, connected to opposite points of the short tube-section 33, and preferably over pulleys 41 within said guides, and are finally extended downwardly. In the operation of the hood when the two ropes 39 39 are pulled downwardly together it has the elfect of drawing the hood- sections 31 and 32 together and downwardly, and hence lower the discharge end, the spring 36 by such action being stretched. If pull on the ropes or cables is removed, the spring contracts, and thereby raises the hood-sections, and consequently the discharge end is raised. The swivel connection formed by the annular rib or rim 37 and the straps 38 enables the discharge end of the hood to be directed either to one side or the other simply by pulling on one or the other of the ropes. Forinstance,if the righthand rope is pulled the hood will be turned so as to direct the discharge to theleft, whereas if the left-hand rope is pulled the hood will be turned so as to direct the discharge to the right.

While I have herein shown the hood as composed of two sections 31 and 32, yet it will be u uderstood that more of these sections may be provided, if desired, or simply one section of hood may be employed.
