BOLTING-REEL.

SPECIFICATION forming part of Letters Patent No. 380,527, dated April 3, 1888.

Application filed May 14, 1887. Serial No. 238,235. (No model.)

To (ZZZ whom 2'25 may concern.-

Be it known that I, ilIACONIUS SHANER, a citizen of the United States, residing at Beaver Falls, in the county of Beaver, in the State of Pennsylvania, have invented certain new and useful Improvements in Bolting- Reels, of which the following is a specification.

My improvements relate to a reel for bolting flour, meal, and like materials, in which the material being bolted is subjected to air'suction for the removal of the lighter impurities and is fed into the reel. by automatic scoops or con veyers which may discharge below the shaft of the reel.

To these ends my invention consists in certain details of construction hereinafter fully described and claimed.

In order that my invent-ion may be fully understood, I will first describe it with reference to the accompanying drawings, in which- Figure I is an elevation of the head of my improved reel and section of casing and feedbox on line I I, Fig. Ill. Fig. II is a vertical transverse section of the reel and easing on line 11' II, Fig. III. Fig. III is a vertical longitudinal section thereof on line III III, Fig. I

1', part of the visible wings being broken away and showing them cut off at an angle, the bolting-cloth being shown. beyond such broken portion.

1 may represent a casing of ordinary shape. 2 is the feed-box, supplied with middlings, meal, or flour through spout'3.

4 is the cloth of the reel, carried by skeleton 5 from shaft 6 in customary manner. The shaft is mounted in the ends of the casing 1 and is driven in any manner.

The head 7 of the reel is made imperforate. Meal is carried from the feed-box 2 into the reel by means of scoops or elevators 8, open at both ends and shaped so as to discharge material on the cloth, preferably below the shaft. These scoops are arranged spirally relatively to the reel, and are supported on the outside thereof, the outer ends or months of which are arranged at the outer end of the reel, while their inner ends, by reason of the scoops being arranged spirally, deliver the material toward the other end of the reel.

The tail 9 of the reel is open around the shaft 6 to correspond with an opening in the side of a vertical air-trunk, 10, arranged between the tail of the reel and the end of the casing and communicating with the eye of an exhaust-fan, 11. This fan takes up the lighter impurities from the material and blows them away to the dust-room, the air to supply the fan coming partially through the scoops 8, but mainly through the meshes of the cloth, where it assists the bolting action materially by keeping the meshes clear. To supply air through the casing for this purpose, any desired number of holes, 12, are provided in the sides of the easing near the top, said holes having suitable valves for regulating the supply along the entire length of the casing. The draft can also be regulated by cut-off slides, either in the airtrunk or at the fan. To prevent air from passing into the trunk 10 between the latter and the tail of the reel, a packing, 13, is provided around the opening in the end of the reel. Preferably sheep-skin with the wool on is used, the wool, which is turned outward, affording a soft tight cushion having little friction.

At bottom the air-trunk 10 has a valve, 10 which may be opened to allow such heavy matter as has dropped therein after entering the trunk to be diseharged.

I guard against the carrying away of any valuable part of the material by the fan, and at the same time increase the effectiveness of the bolting operation, by providing wings 15 16, arranged in pairs, running from head to tail of the machine. Of these wings, 15 is flat and is arranged to receive the material as it falls on the rising side of the reel and throw it back on the cloth, thus spreading it evenly over the latter. The other wing, 16, tightly fixed to wing 15 near the cloth, projects within the inner edge of the wing 15 of the adjoining pair, and is then turned outward to such an extent as to allow a narrow passage between the two wings for the passage of the lighter impurities as they are drawn off by the fan, and afford a trap, 17, which catches any heavy material falling toward the center, and at the descending side of the reel discharges it onto the cloth.

It will be seen that as the material flows in a thin sheet from the wings to the cloth it is subjected to a blast of air passing through the cloth and a separation is thus made the entire length of the reel. The impurities drawn through the openings between the wings are prevented by the overlapping of the Wings from returning until they are discharged from the reel.

The tailings are discharged through openings closed by valves 18, hinged at 19 and having stops 20 extending radially from and secured by nuts 20 on the periphery of the reel and located entirely at the free ends of the gravity-valves for limiting their fall. These valves open automatically on the lower side of the reel to discharge the offal, and close automatically at top to stop the flow of air into the reel.

The usual oonveyers, 21 22, and cut-off slides 23 are provided at the base of the casing for keeping the screenings and offal separate and conveying them away.

Having thus described my invention, the

following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination of a rotary cloth or screen, a suctionfan connecting with the interior thereof, and wings arranged within the screen in pairs, the members of each pair being close together at their outer ends and slightly separated from the adjoining pairs at their inner ends and projecting one beyond the other at said inner ends, substantially as and for the purpose set forth.

2. The combination of a rotary cloth or screen, a suction-fan connecting with the interior thereof, and wings arranged within the screen in pairs, one member of each pair projecting beyond the inner end of the adjoining member of another pair and being there provided with a trap, substantially as and for the purpose set forth.
