PNEUMATIC-STACKER HOOD.
Specification of Letters Patent.
Patented Dec. 22,1914.
Application filed October 18, 1913. Serial No. 795,884.
To all whom it may concern:
Be it known that 1, AUGUST P. DETER- MANN, a citizen of the United States of nmerica, residing at Lyons, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Pneumatic-Stacker Hoods, of which the following is a specification.
The invention relates to an improvement in hoods for pneumatic straw stackers, oomprehending particularly a hood constructed to permit the delivery of the material from the hood at different angles, to dissipate the air blast at the delivery end of the hood to avoid interference with such delivcry, and to adjust the size of the delivery opening to compensate for different conditions of the material.
The main object of the present invention is the provision, in a hood for pneumatic straw stackers of means for deflecting a portion of the blast in a direction away from the delivery of the material, and for dissipating the remaining portion of the blastby dividing the same into a series of finely divided streams which are carried wholly beyond and in a direction away from the material being delivered, hence insuring the delivery of the material free of the spreading influence of the blast.
A further object of the invention is the mounting of the blast dissipating means so that it may be utilized for directing the delivery of the material from the hood, and the provision of means whereby such dissipating means may be manually adjusted to deliver the material at difierent angles from the hood.
A further object of the invention is the provision of means for adjusting the throat plate at the delivery opening to vary the size of said opening as may be desirable under different conditions of delivery.
The invention in its preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in elevation illustrating the trunk of a pneumatic stacker, my improved delivery hood being shown connected therewith. Fig. 2 is a plan of the improved hood. Fig. 3 is a side elevation of the same. Fig. l is a horizontal section on line L-4 of Fig. 3. Fig. 5 is a longitudinal vertical section through the hood. Fig. 6 is a section on line 6-6, Fig. 5. Fig. 7 is an end elevation of the hood.
The present invention is directed particularly to an improvement in the construction of the delivery hood, and it is of course to be understood that I contemplate the use of the hood described with any type of stacker. For the purposes of a complete understanding of the invention, however, I have conventionally illustrated in Fig.1 of the drawings the cooperating parts of the stacker, in which figure it will be seen that my improved hood 1 is designed for removable connection to the free end of the movable trunk 2 of a pneumatic stacker, which trunk, through the medium of the usual elbow 3, is connected to the fixed trunk 4-, and adapted for desirable and necessary adjustment through the medium of adjusting mechanism, designated generally by 5.
The improved hood 1 comprises a tubular extension 6, designed to engage the free end of the movable trunk 2, and beyond the extension said hood includes side plates 7 and 8, which extend in spaced parallel relation from the extension, and are spaced apart to provide the usual opening therebetween for the delivery of the material forced through the trunk. The lower forward edge of the extension 6 is arranged at right angles in the side plates 7 and 8, and a bar 9 connects the side plates immediately forward of this edge, forming with such edge a guide channel 10 extending completely across the delivery space. Elongated slots 11 are formed in the side plates 7 and 8 extending forwardly at an upward incline from the guide channel 10, and a rod 12 is mounted for sliding movement in the slots and provided with clamping means 13 whereby it may be held in any desired position longitudinally of the slot. The rod extends transversely of the hood between the side plates 7 and 8, and loosely mounted on the rod is a throat plate 14. The throat plate is of a size to bridge the space between the side plates 7 and 8, and its free rear edge is inserted in the guide channel 10.
From the above description, it will be obvious that the throat plate may be adjusted to vary the extent of its projection beyond the free edge of the tubular extension 6, and clamped in such adjusted position, thus controlling the size of the delivery opening in order to compensate for different conditions of the material being handled.
A shaft 15 is rotatably mounted on the upper edge of the side plates 7 and 8, said shaft extending transverse the space between said plates, and being arranged in advance of the forward edge of the tubular extension 6, thereby providing between said shaft and edge an opening 16 providing the initial air outlet. This opening immediately overlies the throat plate 1%, and as the latter inclines forwardly and upwardly, it will be obvious that air striking the throat plate will be in part directed through the opening 16.
Secured upon the shaft 15 and projecting forwardly in a downwardly curved plane are a series of spaced bars 17 forming what I term the straw guide, the lower ends of the bars terminating slightly above the lower edges of the side plates. The shaft 18 is rotatably mounted on the upper edge of the side plates, in advance of and par-,
allel with the shaft 15, and a series of fingers 19 are secured to the shaft 18, and project therefrom in a forwardly and downwardly curved direction, the fingers 19, constituting what I term the air deflector, and being arranged practically in upper and lower sets, the spaces of the respective fingers of one set being offset with respect to the spaces between the fingers of the other set.
A lever 20 is connected intermediate its ends to one end of the shaft 15, and an arm 21 is similarly connected to and depends from the shaft 18. The lower end of the lever and the free end of the arm is COI1-| nected by a link 22, by which connection the shafts l5 and 18 may be simultaneously operated. A spring 23 is connected to the lower end of the lever 20 and to the underlying side plate, a stop 24; projecting from the guide plate to limit the movement of the lever under the influence of the spring. The upper end of the lever is adapted for manual operation through the medium of a cord 25 or other suitable flexible connector.
The operation of the air deflecting construction herein described is similar in all respects to that described and claimed in a patent issued to me July 1, 1913, #1,066,260, and the present invention is directed more particularly to adjusting the straw guide and air deflector, and to a simplified means of adjusting the throat plate.
Through the means described for accomplishing the various adjustments, it will be apparent that the straw guide and air deflector may be swung to any desired elevation and thus direct the material at practically any angle from the hood, it being understood that the control of the air currents, as described in the patent referred to, is exactly the same in all adjusted positions of the guide and deflector. The initial escape of the air through the outlet 16 dissipates a portion of the blast, which together with the dissipation of the remainder through the straw guide and air deflector prevents a reaction of such blast upon the material which would have a tendency to scatter the material delivered and being delivered. The adjustment of the throat plate provides for varying the size of the delivery opening in accordance with the condition of the material being handled.
The invention provides a hood in which the air blast is prevented from interfering with the delivered material, and in which the means for controlling the air blast and for controlling the delivery of the material are adjustable to vary the direction of delivery while governing the air blast.
What is claimed is 1. A hood for pneumatic stackers formed with a delivery opening, a straw guide carried by the hood beyond the opening and formed for the passage of air therethrough, an air deflector arranged beyond the straw guide, and means for simultaneously adjusting the straw guide and air deflector independently of the hood.
2. A hood for pneumatic stackers formed with a delivery opening, a straw guide movably mounted on the hood, an air deflector movably mounted on the hood, and man ually operable means for simultaneously adjusting the straw guide and air deflector in dependently of the hood.

4. A hood for pneumatic stackers including side plates formed with elongated inclined slots, a rod mounted for adjustment longitudinally of the slots and extending transverse the plates, a throat plate carried 7 l by the rods between the side plates, and means for guiding the free end of the throat plate.
5. A hood for pneumatic stackers including a tubular portion and side plates proj ecting in spaced parallel relation therefrom, each of said side plates being formed with an elongated slot, the side plates being connected by a bar adjacent to and forming a channel with the edge of the tubular portion, a shaft mounted in the slot, and a throat plate mounted on the shaft with its free edge in the channel.
