TELESCOPIC SPOUT FOR GRAIN-DRILLS.

Specification of Letters Patent.

Application led January 23, 1911.

Serial No. 604,165.

To all 'whom 'it may concern.

Be it known that I, O'r'ro G. Rinske, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Telescopic Spouts for Grain-Drills, of which the following is a specification.

This invention relates to a telescopic spout intended to be used particularly with double disk grain drills and has for its objects to provide a spout of simple arrangement, but which shall be capable of the maximum amount of vertical adjustment and elongation; to provide a spout which can be cheaply and easily made from sheet metal; to provide a spout which can be readily attached to a grain drill and assem bled thereon, and which when assembled and attached to a grain drill will not pull away therefrom; and to provide a spout which may be attached to a grain drill without the need of special fastening devices other than those in the spout itself, thus making it necessary only to provide a hole or opening in the grain drill through which the spout passes.

Other objects and uses will appear from a detailed description of the invention which consists in the features of construction and combination of parts hereinafter described and claimed.

Referring now to the drawing, Figure l shows a side view of one form of grain drill having my improved spout attached thereto, the disk on the near side being re moved to show the spout beneath, and the entire spout being shown in raised position by means of dotted lines, but not in elongated position; Fig. 2 is a side view of the spout partly in section, showing the manner in which the flange on the inner tube engages the wire which is woven through the outer tube; and Fig. 3 shows an enlarged cross section of the spout taken on the line 3-3 of Fig. 1, lookin in the direction of the arrows and showlng how the wire performs a double function in thatit holds the inner and outer tubes of the spout in proper engagement with each other, and in that it prevents the spout as a whole from dropping downward below a certain point.

In the embodiment of my invention, I provide an inner and an outer tube each of proper size and length to permit the necessary amount of telescopic adjustment in use. I then provide an outwardly flaring flange on the lower end of the inner tube and weave a wire or the equivalent through the outer tube in such manner as to prevent the flange 'of the inner tube from pulling past the wire during elongation, and in such manner that the wire also prevents the spoilt as a whole from dropping below a certain point with respect to a grain drill bracket or curved plate. I also provide a peculiar form of casting for connection to a grain box and attach the same to the upper end of the spout in a peculiar manner.

Referring now to the drawing the bracket of a grain drill is designated by the numeral 4. The numeral 5 designates the disks, the nearer of which is removed from Fig. l as before stated. An outer tube (i passes loosely through a hole 7 in the shoe of the grain drill. This hole should be of such size as to permit the necessary amount of swinging motion of the spout in service. The lower end of the outer tube is flared out to provide a vflange S of sutlicient size to prevent the tube from pulling up through the hole. It is desirable to provide means for preventing the rotation of this outer tube in service. Inasmuch as the tube is preferably made from sheet metal, a seam 9 is provided at the point where the tube sheet is brought together. I have discovered the fact that this seam may be of such size that if a notch 10 is provided in the hole, and the seam is registered with the same` rotation of the tube will be prevented. I provide an inner tube `1l somewhat smaller than the hollow of the outer tube so that an outwardly flaring [lange 1S), on the lower end of the inner tube will slide loosely up and down in the outer tube. By forming the seam 13 of the inner tube so that it faces inward it does not in any way interfere with the movements of the tubes with respect to each other. A wire 14:, woven through the outer tube in a peculiar manner substantially as illustrated, performs a double function. At its portions l5, where it loops back to reenter the outer tube, and 16 where it is twisted together, it projects out beyond the'outer tube a sutlieient distance to prevent it from dropping down through the hole 7. At the points 17 and 18 Where it passes inside of the outer tube it projects inwardly a suliieient distance to prevent the flange of the inner tube from pulling past it, thus keeping` the inner tube in engagement with the outer tube.

A study of the relative arrangements of the flanges 8 and 12, and the wire 14 with respect to the bracket shows that after the spout is once assembled, its various parts cannot be withdrawn from the bracket. When the spout rests in its lowermost position, as illustrated by the full lines in Fig. l, the wire prevents it from falling below the point illust-rated. When the inner tube is pulled up, it first elongates in the manner shown in Fig. 2 until the flange 12 strikes the wire 18. During this movement the outer tube remains in its lowered position so that the point of grain delivery remains at substantially the same elevation for all movements of the inner tube until the flange of the same rises high enough to strike the wire. This amount of movement is substantially equal to the radius of the disk and is considerable. In Jfact, it is ordinarily suf'- ficient so that ordinarily the grain delivery is always at substantially the same elevation on the disks. In case of excessive rising of the inner tube, its flanges will strike the wire and thus raise the outer tube also. The maximum amount of movement is that in which the inner tube raises the outer tube untilthe flange of the latter strikes thelower face of the bracket. In other words, my arrangement of tubes is such that during all ordinary movements of the grain box with respect to the disk the point of delivery on the disk will remain constant, but provision is still made for excessive movements in addition.

' It is seen that the parts of my spout can be very easily assembled together. The outer tube is first inserted within the hole of the bracket from beneath and then the inner tube is shoved down into the outer tube. Thereafter, the wire is woven into place and the several parts are locked together. The operation of weaving the wire, however, is a very simple one and can be easily performed by reason of the fact that the outer tube may be raised up in the bracket a suflicient amount so that the wire can be easily inserted.

` The casting 19 which is attached to a grain box is provided on its lower end with a rib 20. The upper portion 21 of the inner tube is then flared out and bent inward at 22 to engage the rib, and the wire 23 serves to secure a firm grip between the parts. This wire may be tightly bound around the tube so as to draw the same in against the casting above the rib and then the edge 24 of the tube may be bent down over the wire as illustrated.
