DEFLECTOR F O R BLAST-STACKERS.

SPECIFICATION forming part of Letters Patent No. 549,121, dated November 5, 1895. Application filed July 22, 1895. erial No. 656,709. (No model.)

To all whom it may concern.-

Be it known that I, FRANK B. GARNES, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Deflectors for Blast-Stackers and I do hereby declare the following to be 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.

This invention relates to that improvement in thrashing machines known as. blaststackers, by which the straw and chafi are carried pneumatically through a pipe or airtrunk and delivered at the outlet end thereof.

The object of this invention is to obviate a common objection to such stackers, that they deliver the straw and chaff too forcibly, and to provide means for breaking the force of the blast at or a little beyond the outlet end of the air-trunk, whereby the straw and chaff are delivered much more lightly on the stack, the advantages of which will hereinafter more fully appear.

The invention consists in a kind of chute mounted near the outer end of the air-trunk and adapted by its peculiar nature and construction to break the force of the blast at the delivery end of the air-trunk and aiford a passage through which the straw and chaff are suitably carried to the stack.

In the accompanying drawings, forming a part of this specification Figure 1 is a view of a device embodying my invention as seen from the front side or that side nearest the operator of the swinging air-trunk. Fig. 2 is a longitudinal section, in a vertical plane, of a modified and preferred form of the same.

Similar letters of reference indicate corresponding parts.

The objections to the blast stacker as above suggested are due to the fact that in order to carry away the straw and chaff under all circumstances a powerful blast is required; but the effect of this is to deliver such straw, &c., in a torrent that makes it impossible for men to stand on the stack and dispose of it at all. This prevents the formation of a symmetrical stack of suitable height and produces a low flat stack, over which cattle and other stock climb instead of eating into the sides thereof. It is further to be noted that the force with which the straw is ejected is such as to drive it tightly together, so that it is practically impossible to pitch it with a fork, and in feeding it or utilizing it for other purposes it can only be handled by cutting down at the sides with a hay-knife. This compactness of the material is further objectionable from the fact that the straw, which is generally nosed aside, is jammed in so tightly that cattle cannot get at the chaff, which they relish, and so the stack is practically valueless for forage.

My invention contemplates the use of a blast to carry the straw to the point of delivery, (it being in so far of great utility,) but breaking and diffusing the blast at this point, and thereby securing a comparatively gentle discharge of the straw to obviate the difficulties above mentioned.

Referring now to the drawings, A designates the air-trunk, which has quite a long beveled opening-at the discharge end and is preferably provided with a partial elbow A to carry the straw downward somewhat as discharged. To the upper side of the air-trunk is secured a bail B, and on the laterally-extended ends of this is pivotally mounted a ring 0, having an ofiset C under the airtrunk to allow for tilt, according to the inclination of the air-trunk. To the rear portion of this ring (the farther portion in Fig. 1) is secured a concave hood D, of considerably larger area than a transverse section of the airtrunk and set at some distance beyond the end thereof. This concave serves the double purpose of breaking and diffusing the blast and directing and controlling the flow of straw backwardly. In practice it is formed of strips of sheet metal and is preferably ovoid in form, though the particular form is not of great importance. Its upper end should eX- tend somewhat higher than the pipe normally, so that when the pipe is tilted upwardly the chute, which should normally hang in a practically-Vertical position, catches all the straw discharged therefrom and directs it downwardly or outwardly through the basket-like outlet to be hereinafter described.

To secure the greatest efficiency in breaking the force of the blast and diffusing it, this hood should be set at some distance from the the inclination of the air-trunk.

outlet end of the air-trunk, so that the air may spread in every direction as it escapes therefrom. This of course greatly reduces its force, and instead of the straw being driven downwardly with great velocity it is thrown out in a moderately rapid stream considerably spread out and ultimately reaches the stack in a fit condition to be handled or piled automatically in a stack of proper dimensions.

To the ring 0 C are fastened a series of rods E, extending downwardly in a symmetrical basket. In practice the lower outlet end of the basket is considerably contracted, so .as to retard the flow of the straw, &c., collected above. In the simpler and preferred form shown in Fig. 2 these rods are fastened securely to the ring at the upper end and are free of any connection below the ring. They are made of flexible wire, so that when the discharge from the air-trunk is excessive they may spring outwardly and thus dilate the mouth of the basket.

In Fig. 1 is shown a construction admitting of the control by the operator of the contraction or dilation of the mouth of the basket. This consists of a ring F, through holes in which the rods or fingers pass loosely. One side of the ring is supported on one or more collars f, secured to as many of the fingers. To the other side is connected a pair of cords I I, uniting in a single one I, by means of which the .ring is tilted to contract the mouth of the basket. The gravity of the ring enlarges the mouth when the pull of the cord is relaxed.

In practice the ring C G is made of angle iron or steel. Holes are made for the fingers in both flanges and the bent upper ends of the fingers pass through both holes and are riveted fast in one of them. They are thus held firmly in their proper position.

Normally the basket hangs pendent from the bail, which should be at about the center of gravity. In this position the straw is discharged straight downwardly, whatever be Provision is made for turning the basket outwardly, however, so as to throw the straw over as wide an area as may be desired. This is simplya cord connecting with the upper portion of the apparatus, as to a lever G or G. By pulling this cord the lower end of the basket swings baekwardly, returning to normal position when released.

Having thus described my invention, I claim 1. The combination with the air-trunk of a blast stacker, of a basket-like receptacle of considerably larger area at the top than the discharge end of said air-trunk, and having a contracted outlet at the other end, mounted contiguous to the discharge end of said airtrunk, and adapted to receive the contents thereof and retard its flow to the stack.

2. A basket like receiver for the contents of a blast-stacker air-trunk, of considerably larger area at the upper end than the discharge end of said air-trunk, and wit-h a contracted, open lower end, automatically dilating and contracting according to the volume of straw passing through it.

3. The combination with the air-trunk of a blast stacker, of a conical receiver for the c011- tents thereof, the upper, receiving end being of considerably larger area than the end of the pipe, to allow the straw to spread out, and the lower end contracted to retard its flow.

4. The combination with the airtrunk of a blast stacker, of a receiver for the contents thereof, the upper, receiving end of the receiver being of considerably larger area than the outlet of the air-trunk, and having an open, contracted, bu-t'dilatable lower end.

5. A receiver for the contents of the airtrunk of a blast stacker consisting essentially of a ring adapted to be suspended from said air-trunk, and a series of depending and inwardly inclined fingers or rods secured thereto.

6. In a device of the class specified, the combination with suitable means for suspending it from the air-trunk of a blast stacker, of a blast-diflusing hood, and a conical, basketlike receptacle for the straw, substantially as and for the purpose set forth.

7. The herein described straw receiving and retarding basket composed of the ring 0 C of an gle-iron or steel, and flexible, inwardly bent fingers or rods secured to said ring by riveting the angled, upper ends of the rods in holes in one of the flanges, the body of the rods passing through the other flange, as described.

8. The combination with the air-trunk of a blast stacker, having a beveled outlet and a downwardly inclined partial elbow, of a straw receptacle composed essentially of a large, concave blast-diffusing hood, and a basket like receiver for the contents of the air-trunk, substantially as and for the purpose set forth.

9. The combination with the air-trunk of a blast-stacker of a bail having lateral bearin projecting some distance from the air-trunk, and about central therewith, a ring pivoted thereon, and a concave hood of substantially ovoid form attached about midway of its length to said ring, with means for tilting the same, substantially as described.

10. The combination with the air-trunk of a blast stacker, of a bail having lateral bearin project-in g about diametrically each side ofthc same, a ring pivoted thereto,a concave hood, substantially ovoid in form secured to said ring, and a basket-like chute also attached to said ring, with means substantially as (l escribed for tilting the same.

In testimony whereof I afiix my signature in presence of two witnesses.
