GRAIN-SPOUT.

SPECIFICATION forming part of Letters Patent No. 639,506, dated December 19, 1899.

Application filed August 15, 1899 Serial No. 727,268. (No model.)

To all whom it mcoyooncern:

Be it known that I, GEORGE H. BIROHARD, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain useful Improvements in Grain-Spouts; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to an improvement in grain-spouts, the aim ofmy invention being to provide a grain-spout adapted to be secured to the spouts as ordinarily constructed and already in position, my invention more particularly comprising an attachment to be used in connection with grain-spouts already in use.

In the accompanying drawings I have shown in Figure 1 a perspective view, with portions broken away, of an ordinary grain-spout provided with my improved attachment. Fig. 2 shows a detached detail of the shifting sleeve, while Figs. 3 and 4 show enlarged details of the holders as used in my invention.

To an ordinary grain'spout 3, provided with the usual hopper 2 and operating-stem 14, which is controlled by the usual looking-lever 16, so that the spout 3 may be revolved and adj ustably secured, is secured my invention. The grain-spout 3 is usually provided with a tube 4, which is most commonly slightly conical and secured to the spout 3 proper by any suitable means. Secured to this tubing 4 is a holder 5, which holder 5 is in two parts, preferably made of strap metal, and is. secured by the bolts 22 and 23, as is shown in Fig. 4, the bolt 22 preferably being surrounded by a section of iron tubing to hold the two half sections 5 a proper distance apart. These half'sections 5 at the upper end are united by means of a bolt 21, so that I provide a clamping-holder comprising the two half-sections 5 5, which can be adjustably secured to the spout-tubing 4. Secured to the lower end of the spout-tubing 4 is a second split collar comprising the two similar sections 6 6, united by means of the bolts 18 and 19, the bolt 19 again being provided with a bit of iron tubing to keep the two collar-sections a suitable distance apart at their lower ends.

Working upon the lower bolt 23 is a bellcrank 11, pivotally secured thereon, and extending from this bell-crank 11 is an ordinary coil-spring 13, secured at its remaining end to the bolt 22, so that this lever 11 has one end normally drawn toward the holder 5 5.

\Vorking upon the tube-section 20 of the for-' ward holder 6 6 is a rod 8, (shown in Fig. 2,) which rod 8 is provided with the ear 9 and a sleeve 7, and this sleeve 7 works upon the spout-tubing 4, so that this sleeve 7 may be made to form a prolongation of the spouttubing 4. In Fig. 1 I have shown in dotted lines the inner position of this sleeve 7. The holders 5 and 6 are secured by means of suit able pins 25, which form part of the tube 4 and pass through suitable openings 25, as is shown in Fig. 3.

Secured to the ear 9 is an ordinary rod 10, which by means of the pin 26 is secured to the bell-crank 11, and from this bell-crank 11 extends an operating-cord 24, so that this sleeve, bymeans of the spring 13, is normally forced outward to form a prolongation of the spout-tubing 4, as is shown in Fig. 1.

Now should at any time the grain-spout be shifted so as to empty the grain into another bin the operating-strand is drawn downward to carry upward the sleeve 7, so that this sleeve 7 would be carried outof the bin-open ing, in which it would rest while grain was passing through the spout and be held upward until the grain-spout was again pr0perly positioned, the grain-spout being operated, as usual, by means of a suitable lever 16, and as soon as the grain-spout was given the proper position the operating-cord 24 would be released, so that this sleeve 7 would move forward and lock into the proper opening in emptying the grain.

My holders 5 and 6 being in two parts, secured by simple bolts, can be readily secured to any grain-spout already in position, and as the parts are very simple the device can be readily operated, and,

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is

1. The combination with a grain-spout, of a holder adj ustably secured to said grain-spout,

the holders 5, 5, adjustably secured thereto, the bell-crank ll Within said holder, the spring 13 uniting said bell-crank to said holder, the collar 6 secured to said grainspout, the sleeve 7 working upon said grainspout, said sleeve 7 being provided with a rod 8 held by said collar 6, the bar 10 securing the rod 8 to said bell-crank 11, and a strand secured to said bell-crank.
