PN EUMATIC STRAW-S'TACKER.

SPECIFICATION forming part of Letters Patent No. 633,199, dated September 19, 1899. App on filed January 20, 1899. Serial No. 702,818. (No model.)

To all whom itmay concern:

Be it known that we, EDWARD HUBER and JACOB W. MILLER, citizens of the United States, residing at Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Pneumatic Straw-Stackers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in swinging hoods for pneumatic straw-stackers.

The object of this invention is to provide an intermediate swinging hood between a stationary hood and an outer swinging hood mounted on the outer end of a pneumatic straw-stacker for controlling the throw of the straw independent of such outer hood.

Another object of this invention is to provide each of the swinging hoods with a cutout portion for causing the straw to string out more, whereby the stack is bound together instead of the straw dropping in bunches, and thus making a more uniformly even stack.

This invention also relates to details of construction hereinafter appearing and particu larly pointed out in the claims.

In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure 1 is a plan view of the invention applied to a pneumatic straw stacker Fig. 2, a side elevation of the same on the line 00 a: of Fig. 1; Fig. 3, an inverted plan view of what is shown in Fig. 1; Fig. 4, a side elevation of the same; Fig. 5, a Vertical sectional View on the line y y of Fig. 3; Fig. 6, an end eleva tion of our device complete; Fig. 7, a detail interior View of the intermediate swinging hood and the outer swinging hood, and Fig. 8 a sectional view on the line 2 z of Fig. 1.

The letter A represents a pneumatic strawstacker delivery-pipe, on the outer end of which is mounted a head B. In this head B is mounted a fan 0, adapted to be driven by the air passing through the stacker. end of the fan-shaft is mounted a worm D, which meshes with a worm-gear E by a bracket secured to the head. A pi'tman G, connectingwith the worm-gear and hinged hood H, is reciprocated by said gear, which causes the hinged hood to swing up and down on its pivots I.

On one Our present invention has reference more particularly to theintermediate hood K,which is adapted to be operated independently of the outer swinging hood II. This intermediate hood is pivoted on the same studs I as the hood H and is normally heldin its lowest position by a helical spring L. Both of these pivoted hoods are adapted to swing up over a stationary hood J, attached to the forward end of the hood, as clearly seen in Figs. 1 and 2. A projection M extends from the intermediate hood and has attached to its outer end a cord or rope N, which runs along down to the lower end of the pneumatic stacker. 'By pulling on this rope the inner hood may be raised to any desired position, but is returned to its lowermost position by the spring L, above referred to, when the cord is released. From Figs. 6 and 7 particularly it will be seen that the outer hood, as also the intermediate hood, is out out or notched, as shown at O and I, respectively. These notches are for the purpose of causing the straw to be strung out as it'leaves the pneumatic stacker instead of passing out in chunks and small piles, as it were, these notches acting to relieve the straw in the hoods, so that there is a more continuous stream or flow of the straw. Thus all parts of the stack are properly bound together, which is not the case when the straw leaves the pneumatic stacker in chunks and bunches. From the above description it will be understood that the outer swinging hood is constantly operated up and down by reason of its connection with the driving-gear, which gear receives motion through the driving-fan 0, above referred to. In order to control the extreme outward throw of the pneumatic carrier when the outer hood is raised, the intermediate hood is brought into operation, and when the outward throw is desired to be lessened but a slight amount the intermediate hood is lowered but little; but if it is desired to limit the outward throw a greater amount the intermediate hood is lowered still more, its movement being controlled by the rope N, above referred to. Then the intermediate hood is in its lowermost position, it will throw the straw to its extreme inner limit.

From the above description it will be seen that the outer hood continuously moves up and down to throw the straw from one side of the stack to the other automatically,while the inner hood is. operated by means of a cord or rope in one direction and a spring in the opposite direction to respectively limit the outward movement of the straw and to direct the straw to its extreme innerlimit. It has been found in actual practice that this intermediate independently-adjustable hood is of great practical importance, especially when topping out or drawing in a stack to properly point it. The outer hood will have the same movement at all times, while the inner hood may be set to limit the outward throw of the straw and cause it to throw it to its innermost limit.

It will be observed that the head B is rotatably mounted on the delivery-pipe A. This is for the purpose of directing the straw each way from the pneumatic stacker. In order to partially rotate this head, a rope R or other suitable device is attached to alugQ, secured to the head, such rope ordevice being shown particularly in Figs. 1 to 4. The ends of the rope pass over rollers S, carried by a bracket T, bolted or otherwise secured to the delivery-pipe A.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. In a pneumatic stacker, the combination with adelivery-pipe, of a head mounted thereon, an automatically-operated hood pivoted to said head and independently-adjustable means for controlling the throw of the straw, substantially as shown and described.

2. In a pneumatic straw-stacker, the combination with a pneumatic delivery-pipe, of a head mounted thereon, an automatically-operated hood pivoted thereto, means for automatically operating said hood, a stationary hood secured to said head and an intermediate hood between said stationary hood and said automatically-adjustable hood adapted to be adjusted to regulate the outward and inward throw of the straw independently of said antomatically-operated hood.

3. In a pneumatic straw-stacker, the combination with a delivery-pipe, of a head carried thereby, a fan carried by said head and adapted to be operated by the air-blast passing through said pipe, a worm on the outer end of the fan-shaft and a worm-gear meshing therewith, an outer hood pivoted to said head, a pitman connecting said hood and gear together and adapted to operate said hood, a

stationary hood secured to said head, an intermediate hood, and means for adjusting said intermediate hood independently of said automatically-operated hood, substantially as shown and described.

4. In a pneumatic stacker, the combination with a pneumatic delivery-pipe, of a head rotatably mounted thereon, a fan carried by said head adapted to be operated by an airblast passing through said pipe, a worm-gear driven by said fan, an outer hood and an intermediate hood pivoted to said head, a pitman connecting said worm-gear and said outer hood whereby the outer hood is automatically operated, a spring for normally holding said intermediate hood in its lowermost position and a projection from said hood to which the rope or cable is attached whereby the intermediate hood may be adjusted to different positions as desired, all substantially as shown and described.

5. In a pneumatic straw-stacker, the combination with a delivery-pipe, of a head carried thereon, a swinging hood carried by said head and having a notch or opening therein, and means to automatically operate said hood, substantially as shown and described.

6. In a pneumatic straw-stacker, the combination with a deliverypipe, of a head mounted thereon, and having a stationary hood secured thereto and an outer and an intermediate hood pivotally connected there with, each of said pivoted hoods having a notch or opening therein extending from their lower edges, and means to operate said hoods independently of each other, substantially as shown and described.

7. In a pneumatic stacker, the combination with a delivery-pipe, having astationary hood connected therewith, of an outer swinging hood and an intermediate swinging hood between said outer hood and said stationary hood, and means to adjust said intermediate hood relatively to the said outer hood and said stationary hood, substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
