ELEVATOR AN D STACKER.

SPECIFICATION forming part of Letters Patent No. 464,530, dated December 8, 1891.

Application filed February 12, 1890. Serial No. 340,211. (No model.)

To all whom it may concern.-

Be it known that we, GUSTAVUS J. STATES and GEORGE E. HALL, both citizens of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented a new and useful hood for elevators and stackers for elevating light substances, such as hay and straw, and especially for such machines as thrashing-machines, which have one elevator deliver the substance being handled to another, which carries it still higher and farther, of which the following is a specification.

The object of our invention is to prevent the substance being handled from being carried away by the wind or any other cause while it falls from one elevator to another, even though the elevator or stacker which receives from the other is continually swinging to and fro. We attain this object by the mechanism illustrated in the accompanying drawings, in Which-- I Figure 1 is a side elevation of a section of a thrashing-machine straw-elevator and swinging stacker in an elevated working position, with the hood and receiver-shield attached and showing the manner of and means for adjusting the hood. Fig. 2is a side elevation showing a section of the two elevators or stackers as they would be when let down quite low, with the hood and receiver-shield attached in their proper working positions. Fig. 3 is a side view showing the hood in its proper position, with the elevator and swinging stacker raised and the swinging stacker swung around to a quartering position. Fig. 4 is a side view showing the hood and the upper part of the elevator folded back onto the lower part of elevator. Fig. 5 is a side elevation showing the hood attached to elevator 1 in position to work in combination with elevator 5 without the use of the receiver 4 in Fig. 3. Fig. 6 is a plan view of the receivershield and the lower bows of the hood. Fig.

7 is a plan View of that bow of the hood which is hinged to the sides of the elevator 1. Fig.

8 is a plan view of the'upper bow or bows of the hood.

Similar numbers refer to similar parts throughout the different views.

The hood 3 is constructed of a series of bows, with canvas or other suitable material stretched from one to the other either on the inside of the bows, as shown in Fig. 1, or on the outside, as shown in Fig. 2. The

lower bows

11 and 12 of the hood 3 are so constructed as to form a perfect or nearly perfect circle, as shown in Figs. 1-, 2, and 6; or they may be constructed with their front and rear parts (either or both) flattened or extending straight or nearly straight across, as shown in Fig. 6. The

bows

13 and 14 are made straight for a short distance at their ends, and then they extend around from one side of the elevator to the other in a semicircular form; or they may be so constructed as to form a short curve on each side a little in front of the end of the elevator and then extend straight or nearly straight across, as shown in Figs. 7 and 8. The bows are all secured to each other by meansof the canvas 10, which is stretched from one to the other.

The hood 3 is hinged to the elevator 1 by means of a stud, bolt, or other suitable device secured ad justably or stationary to each side,

of the elevator lvnear its upper end,and said studs or bolts (which are referred to by Fig. 6 in the drawings) pass through holes in the bow 13 at or a short distance from its ends and through holes in the ends of the bow 14, or the hood 3 may be hinged adjustably to the elevator 1 by the bolt or stud 16, passing through a small roller resting in the slot in ends of bow 13, and when the hood has been adjusted forward or backward to the desired position it may be held there by the use of a thumb-nut on the end of the stud or bolt 16. When the hood is attached adj ustably to the elevator 1, as above described, the how 14 should be hinged to the bow 13 a little in front of the point where the bow 13 is hinged to the elevator, or they may be always connected in this way. (See Fig. 4.)

The swinging stacker 5 may be provided with a receiver-shield 4, by means of which the wind is prevented from blowing up into the lower end of the hood, which would pre- Vent the straw from falling freely on the stacker 5. Although the receiver-shield is a very useful device, yet it is not entirely necessary for the successful working of the hood,

ICC

and therefore it may be dispensed with, (see Fig.:4;) but by its use, in combination with the hood, the hood is sure to work perfectly under all circumstances.

The above-mentioned receiver-shield is constructed as follows: The lower loop 7 of the receiver may form a perfect or nearly perfect circle, or it may be cut away on the upper side, so as not to extend across the elevator or stacker, as shown in Fig. 6. The loop 7 is secured to the stacker 5 by means of the strap iron or braces 8 at the sides and 9 at the rear. To the loop 7 is secured the upper edge of the canvas 6, which hangs down and may be secured at its lower edge to the side and end boards of the stacker 5. When the receiver 4 is so constructed that it extends across the stacker at its upper part, as shown in Figs. 1 and 2, this part of the canvas should hang free at its lower edge and maybe slitted upward in a few places, so that it will not prevent the straw from passing under it,even though it come in large quantities. As the hood 3 is secured to the elevator 1 by means of a hinged bearing, it may be tilted and held in any desired position by means of the rope 15, which is secured to the upper part of the bow 14. and extends back to the upper part of the machine. hen the rope 15 is drawn backward, the upper part of the hood is drawn backward and upward and the lower part of the hood is drawn forward, giving the lower edge of the hood a more slantingposition, thus making it better adapted to operate with the swinging stacker when said stacker is in certain positions. The hood 3 and the upper part of the elevator 1 can be folded back upon the lower part of the elevator or upon the machine (which is usually done when the machine is to be moved) by the operator at the machine pulling on the rope 15, the manner in which the hood folds together being shown in Fig. 5. The upper part of the hood is prevented from being drawn backward only a certain distance by the lower end of the bow 13 swinging back and striking the projecting ends of the cross-bar 20 of the elevator, (see Fig. 1,) and if the operator continues to pull the rope backward after the ends of the said bow come in contact with cross-bar 20 the hood and upper part of the elevator can both be drawn over backward together. The web 2 of elevator 1 is guided over the lower rear edge of the hood by means of the shoes or guide-plates 17 ,which are secured to the elevator 1 by means of the supports 18. The guide-plates 17 serve also to prevent the rear portion of the hood from swinging up and catching the web 2. By the use of the strap 19 the lower part of the hood may be permitted to swing forward and backward, as desired, (as when the hood is being tilted,) and prevented from going only a certain distance downward. The canvas 10 extends below the lower bow or hoop of the hood far enough so that its lower edge will always be below the upper edge of the receiver 4 or the side boards of the stacker 5 when no receiver is used, thus forming a sort of skirt, by means of which the straw or whatever substance is being elevated is conducted to the stacker 5 without its being aifected by the wind. The lower edge of the skirt of the hood may be slitted, so that the straw can pass out under it freely, even if it should come in bunches.

hat we claim as our invention, and desire to secure by Letters Patent, is as follows:

1. The combination, with the elevator, of a flexible hood secured to the upper end of said elevator, the lower end of such hood being circular in cross-section, a stacker arranged in connection with the elevator and hood,aud a circular receiver or guard attached to the lower end of the stacker and adapted to encircle the circular end of the hood, substantially as shown and described. 2. A flexible hood for an elevator and stacker, the said hood being provided with slotted slides to which the ends of the upper how are pivoted, and bolts and thumb-nuts whereby the said upper bow may be adjusted, substantially as specified.

An improved hood for stackers or elevators, comprising the essentially U-shaped upper pivotal bows, the lower circular bows, and the canvas covering attached to said bows and connecting the same to form a complete hood, substantially'as shown and described.

4:. In combination with the hood 3 and elevator 1, the shoes or guides 17, and supports 18, as and for the purpose specified.

5. In combination with the hood 3 and'elevator l, the guides 17, the supports 18, and the adjustable strap 19, substantially as shown and specified.

6. In combination with the elevator l and stacker 5, the hood 3, hinged to elevator 1, the guides 17 and supports 18, secured to said elevator 1, the adjustable strap 19, attached to support 18 and hood 3, and the receiver-sl1ield 4, attached to the stacker 5, all substantially as represented and described, and for the purposes specified, in the accompanying drawings and specifications.
