CORPORATION OF "WEST PNEUMATIC STACKER.

To all 107mm 'it may concern.'

Be it known that I, ALBERT M. Hamas, a citizen of the United States, residing at South Bend, in the county oit Saint Joseph and Sta-te of Indiana, have invented certain new and useful Improvements in Ineumatic Stackers, of which the following is a speciication.

My invention relates to hoods tor pneumatic stackers ot' that character shown and described in Letters Patent No. 845,876, issued March 5, 1907, to Abraham Luke, and consists in certain details oit construction and arrangements oil.E parts whereby I' am enabled to simplify the construction and, operation of such hood and materially improve the eliiciency thereof.

In the acconipanying drawings, which are made a part hereof, Figure l is a side elevation of my improved hood showing the bill thereof in lowered position; Fig. 2 is a similar view showing the bill in raised position; Fig. 3, a bottom plan ot the same, and Fig. at a detail.

In said drawings the portions marked 10 represent the ordinary stacker chute to the outer end of which my improved hood may be rigidly or revolubly secured. Said hood comprisesa lower tubular portion, l1, adapted to be fitted onto said chute 10 in any desired manner, the forward portion of the hood leading from said tubular portion assuming an approximately rectangular form and Composed of the side walls, 12, curved at their outer ends, as indicated by the dotted lines in Fig. 2, and the upper curved wall, 11i, said rectangular portion being open at its under side from the end of said tubular portion 11. In the patent referred to it will be noted that the side walls of the hood are cut away on an incline, and the space therebetween is inclosed by a hinged apron provided with cheeks which overlap said walls. This arrangement I have dispensed with, and cut the side walls of my improved hood on a substantially straight line, leaving said walls of a height to conline discharging material and prevent its lateral escape. At the outer end of the tubular portion 11 I provide an adjustable delector, 15, hinged at 16, which is semi-circular in form and lies within the walls 12, its length being comparatively short in relation to the opening in said hood, and at said hinge' point I also secure a Specification 0f Letters Patent.

Application led May 25, 1910. Serial No. 563,287.

rocker arm, 1.7, which entends around on each side ot' the hood, its ends being provided with eyes, 1S. Near the lower side of said walls 12 I place reinforcing strips, 19, having their ends, 20, upt-urned to act as a stop for the rocher arm 17. By the arrangement just described I am enabled to materially reduce the main hood body in length and other proportions. To the outer upper end ot said hood I hinge a bill, 25, as indicated at .27, and preferably reintorce the lower end of said bill by a strap- 'iron, 2S, to which I attach chains, 2t), or other flexible retainers, and suitably connect them to the side walls or' the hood, lor limiting the upward movement olf said bill .I further connect said hood and bill by a coiled spring or springs, 30, as indicated in the drawing, which normally hold the bill in fully opened position, Fig. the upper side ot' the hood I provide a reinforcing strip, 33, which extends down slightly along each side wall and to which is secured a pair ot' sheaves, Bel, 35. while to the projecting ends, 236, of the reinforcing member 2S, which extend down along each side wall of the bill 25, I secure sheaves, To each end of the rocher-arm 17 I attach ropes or cords, 40, run the same about sheaves 34; and around sheaves 37 and thence over sheaves 35, and connect said cords at the rear of the hood, extending one thereof sulliciently to come within convenient reach of the stacker operator on the machine.

In operation, the bill is normally in the full opened position indicated in Fig. 2, and so ar anged that the discharging material will have free outward passage to t-he fullest extent ot' the outlet of said hood. As it becomes desirable to det-lect material downwardly, the rope t() is pulled, which, through the connection of its split ends with rockerarni 17 and the sheaves described, simultaneously actuates the apron and the bill., so that as said bill is lowering said apron is inclining upwardly, which upward inclination delects the material upwardly to cause it to travel along the upper inner wall of said bill, the upward movement oi said deiiector being limited by contact of the ends of rocker-arm 17 with the projections 20 on said hood. The stream of material is thus contracted as it passes through the bill and is discharged in a compact mass. When said bill is pointed in its lowermost position, as

On v

indicated in Fig. l, the material is discharged toward the separator, so that the building of a stack may be commenced close thereto and the material gradually distributed rearwardly therefrom, as the size and height of the stack increases, by lessening the pull on the cords 40, which permits the bill to automatically rise by the tension exerted thereon by spring 30.

I claim as my invention:

l. A hood for staclrers comprising a body portion having an opening in its under side, an upwardly adjustable semi-circular delector hinged at the lower side of said body portion and extending partially across said opening and within the side walls of said hood, a bill adjustably connected to the body portion and constituting a continuation thereof, and iiexible means communicating with said bill and deflector for simultaneously adjusting the same.

2. A hood for staclers comprising a body portion having an opening therein, an upwardly adjustable dei'lector hinged to the lower side of said body portion and extending transversely across a portion thereof, a rocker-arm on said deiector, a bill hinged to the outer portion of said body portion, and a means communicating with said rocker-arm and said bill for adjusting said deflector and bill.

3. A hood for pneumatic stackers comprising a body portion having an opening therein, an upwardly swinging deliector hinged to the lower side of said body portion and extending transversely across said opening, pulleys on said body portion, an adjustable spring-controlled bill connected to said body portion and having pulleys at its lower sides, and means communicating with said deflect-or and through said pulleys with said bill for adjusting said deflector and bill.

4L. The combination, in a hood for pneumatie staolers, of an open-sided body portion, an upwardly adjustable delector hinged to the lower side of said body portion and extending transversely across a portion of its under side, an adjustable bill at the outer end of said body portion, a rockerarm attached to said delector, pulleys on said body portion, pulleys on said bill, and cords connected to said rocker-arm and passing around said pulleys for adjusting said derlector and bill.

5. A hood for pneumatic stackers comprising a body portion having an opening therein, an upwardly adjustable deflector hinged to the lower side ofsaid body portion and extending transversely across the lower portion of said opening, and means on the side of said body portion for limiting the upward movement of said deflector.

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