JOHN A. wAH'LsTROM, OE SALEM, OREGON.

FLOUR-REEL MACHINE.

SPECIFICATION forming part of Letters Patent No. 484,478, dated October 18, 1892.

Application filed October 21, 1891. Serial No. 409,414. (No model.)

To all whom it may concern:

Be it known that I, JOHN A. WAHLSTROM, a citizen of the UnitedStates of America, residing at the city of Salem, Marion county, State of Oregon, have invented certain new and useful Improvements in Flour-Reel Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in iour reels in which a conical air cylinder or channel is placed and fastened into the ordi-.

nary revolving flour-reel in conjunction with a peculiarly-constructed reel; and the objects of myimprovements are, first, to make a better article of flour, and, second, to carry off by my machine most of the impurities in the stock or feed, Whether being in a coarse or light condition, Without beating these impurities or tailings into the good stock or flour. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure l is a longitudinal section of the whole machine. Fig. 2 is an end view of the feeding end. Fig. 3 is an end View of the further end of the machine. Fig. 4 is a sectional view of the feeding end. Fig. 5 is an end View of the same, with the head H and feeder D removed the better to show the fan-blades, &c. Fig. 6 is a section of the .other end of the reel R, cylinder C, and air-chamber A. Fig. 7 is a View of head L, looking from the inside,

with one of the buckets removed to show opening F.

Similar letters refer to similar parts throughout the several views.

At the further end (meaning that end of the machine which is opposite the stock or feed-receiver) is an air-chamber A, which is stationary, connected with the frame of the machine. Into this chamberA the air enters through an opening B, covered and to be regulated with adjustable slats. From air-chamber A the air enters through spider N into the conical air cylinder or channel C, and, passing through air-openings K of ri m-bracket J, mingles and joins with the stock or feed, which enters through feeder D. At this station the fans E, which are secured to the double reel-head H and H', and which create the suction, will then force by their revolving motion the air and stock into the ordinary portion of the reel R, covered with its siftingcloth, and this forced air thus being mingled with the stock will then force all the coarse and light impurities or tailings to the further end, where the buckets F lift said tailings through the openings F in reel-head L into the tailing-spout V and pass them off, Whereas the good liour is passing through the sifting-cloth, which is spread over reel R, into the conveyers G, finding its ordinary exit and free of tailings or impurities.

The construction of my reel is as follows The conical air-'cylinder C is fastened by spider N and iron rim-bracket J to shaft S. Onto the spider N the reel-head L is securely fastened, whereas to the iron rim-bracket J the reel-head H H is secured. The fans E are secured within this reel-head H H', and especially draw the air from airchamber A through cylinder C and openings K into the reel R. The reel-heads H andL are connected by rods M, made of piping or other suitable material, and by these means the reel R and air-cylinder C are securely connected and held in the proper position and distance from each other while revolving on shaft S. The rings or hubs O, supporting the sifting-cloth, are secured to the rods M by bolts b, as shown, and are flush on outside. On the edges or rims of the reel-heads I-I and L a circular piece of Wood P is secured to nail the sifting-cloth to. This circular piece of Wood P is fastened to the reel-heads H and L by a circular iron plate T (being of same width as piece P) by bolts c, running through plate T, wooden piece- P, and the faces of reel-heads H and L, respectively.

Having thus described the construction of the flour-reel R, with its conical air-cylinder C, the operation is as follows, after the machine is put in motion The air passing through the opening B into the air-chamber A enters through spider N into the conical air-suction cylinder or chamber C, and after.

passing through the same by the drawing force created by fans E passes through the openings K in rim-bracket J, and then joining and mingling With the feed or stock which enters through feeder D. The air thus forced IOO into and mingled with the stock revolves with the same in reel R, and making thereby a cleaner separation of the fiour from its impurities or tailings, and instead of the same being forced with the good flour through the sifting-cloth the air thus created will carry all the coarse and light impurities to the further end of the reel, where thevbuckets F lift said impurities through the openings F in reel-head L into the tailing-spout V, whereas the good flour Iinds its proper exit through the sifting-cloth into the conveyer G, and as a consequence a purer flour is obtained', as the impurities are beingkept from'r breaking fine and thus from mingling with the good flour.

I am aware that prior to my inventionflou-rreels. have been madewith ordinaryreels and sifting-cloth, and I therefore donot claim such a combination broadly/,but

WhatIdo claim as my invention, and desire tosecurre by Letters Paten-t, is.-

1. In agrotary bolt, a reel having an internal air-chamber openy only at` the endsand extending substantially from end to end of the. reel, a stock-feeding device, and a fan arranged to cause acurrent of air to-passthrough said air-chamber and into the space between the air-cylinder and the cloth of; the reel, submanually ask described.

2. Ina rotary bolt, a reel having an internal air-chamber open only atl the ends and extendingsubstantially from. end to end of space between the air-cylinder and the cloth ofthe reel, substantially as described.

' 3. In a rotary bolt, a reel R, al1 air-cylinder C, secured within the same, an air-chamber at one end of said reel, and stock-feeding means at the other, in combination with the fan E,

arrangedv in one endE otv the reel to draw air from air-chamber A through air-cylinder C and drive it into the space between the'aircylinder and the cloth of the reel, substantially as described.

4.k In a rotary bolt, areel R, having heads L and H, bucket-s attached to one of said ends `for lifting the tailingsfrom reel R, an air-cyl- `conical air-cylinder C,secured,to said heads .and having. spiders N and J, a stock-feeder D, anda fan vE for drawing.k air from. air-chamber Athroug-h aircy1inder C and into reel R,

substantially as described.
