Application filed May 25 1893. No model.)

To all whom it may concern: v

Beit known that I, JosEPH MARTIN SonU'rZ', a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin, in the State of Minnesota, have invented certain new and useful Improvements in Perpendicular Flour-Dressing Machines, of which thefol lowing specification is a full, clear, and exact description, reference being also-had to the accompanying drawings, in which 1 Figure 1 is acentral vertical section of the machine. Fig. 2 is adetached detail of a portion of the reel and heater frame, illustrating a variation in the construction. Fig. 3 is a perspective View of a section of the beater frame arrangedas in Fig. 2. Figs. 4 and 5 are enlarged details of the feed-distributing plate. Fig. 6 is a cross-sectional view on the line so an of Fig. 1. Fig. 7 is a planview of the outside of the machine.

A is the outer casing or framework the mechanism is supported.

Bis a step secured in a cross-piece, A, in the lower part of the'frame A, in, which a hollow sleeve, 0, is supported. Upon the upper end of the sleeve 0 a spider or circular frame, 1), is mounted, and attached to this spider D is a ring, E, having an inwardly and downwardly inclining interior, as shown. Journaled in a cross-piece, A', on the upper part of the frame A is another sleeve, 0 similar to and in line with the sleeve 0, and having a spider or frame, D (similar to the spider D,) secured to its lower end.

E is a ring attached to the under side of the rim of the spider D and E? E are two'other in which rings at equal distances apart between the rings E FF, all the rings being connected to each other by half-round upright bars or ribs a, the rings E E inclining inward-like the ring E. The ribs a are arranged at equal distances apart around the rings, as shown in Fig. 3. In the drawings twelve of these ribs are shown; but a greater or less number may be used. The rings E E D E and the ribs a thus form a circular perpendicular, frame, over which a covering'of boltingcloth, 0, will be stretched. i Y

F is a shaft passing loosely down through the sleeves 0'0 and also through the step 13, and is held at its lower end by another step,

1 B and is provided with a belt-pulley, F, by

which the shaft may be revolved. Upon the upper end of the shaft F is a chain-pulley, F connected by an endless chain, F", to a chain-. pulley, F upon a small shaft, F, upon top of the casing A. Connected to this chain-pulley F, so as to revolve with it, is another chainpulley, F connected bya chain. F to achainwheel, F", fast upon the sleeve 0 outside the casing A, as shown. The pulley F is smaller than the chain-pulley F and the chainpulley F is smaller than the chain-pulley F, so that when the shaft F is revolved the spiders D D and the bolting-cloth-covered frame connecting them will also be revolved through the medium of the-chain-pulleys in the same direction, but at greatlyreduced speed. The shaft F will be revolved at about two hundred revolutions per minute, and the bolting-cloth cylinder revolved at about twenty revolutions per minute.

Attached to the shaft F at equal distances from the rings E E E E are spiders G G G, having sheet-metal rings H H H, attached to the outer ends of their arms parallel with and near the inner edges of the rings.

Branching outward from each of the rings H H H tangentially inclined, or nearly so, are upright beaters b, and secured to the hottoms of each of the rings H H H and to the bottoms of each separate set of the heaters I) are plates or disks K K K", the outer edges of the disks and the heaters I) being flush with each other and projecting a short distance beyond the inner edges of the rings E E E E*, as shown in Fig. 1, and as indicated by the dotted-line circle in Fig. 6.

In Fig. 2 a slight-variation is shown in the manner'of arranging the heaters 12 and deflecting-rings E E E, consisting in forming the rings H H H in one continuous cylinder, H,

and forming the plates K K K in rings K around the cylinder H". The rings E E E" are formed with flat portions t, and the rings K provided with inclined scrapers 12,-(see Fig. 3,) which scrape the material off from the fiat parts it. vThe action and results are the same in both arrangements, however. upper ring, H, is a disk, K similar to the other disks, K K K and attached to the shaft F, so as to revolve with it, and upon which Above the IOC the material to be acted upon in the machine is fed through a spout, L. Over the outer edge of this disk K a deflecting-ring, (Z, is secured, to cause the material as it flows over the edge of the plate to fall downward and not be thrown outward by the centri fugal force. The construct-ion of this deflecting-ring is more clearly shown in Figs. l and 5.

M is a spout leading from the space between the casing A andrevolving reel, to conduct the material which passes through the boltingcloth from the machine, while a similar spout, N, conveys thetailings away from the machine.

This machine may be used to separate any of the reduced or partially-reduced particles of grain during the process of milling, but is more particularly applicable to dressing flour, and the operation is as follows: The material is fed in through the spout L upon the plate K, and is forced outward by the centrifugal force and turned downward by the deflectingring d, and falls down between the ring H and upper section of ribs (1, where it is caught by the heaters band thrown outward against the ribs a and bolting-cloth 0. Many of the particles fine enough to pass through the cloth will be driven through by this action, while the remainder will be thrown back again by the revolving ribs against the heaters, and by them again thrown outward against the ribs and bolting-cloth. The material that fails to pass through the cloth falls down upon the inclined ring E, and is by it shot inward and downward between the second ring, H and the next section of ribs 0, where the same action takes place, and so on down through each section until all the particles fine enough to pass through the boltingeloth will have been forced through it, while the coarse tailings only will reach the exit-spout N. By forming the beat ers b in short sections and interposing the inwardlyinclining rings E E E and disks K K K between each section of beaters, the material is prevented from falling downward a longer distance than the length of any one section of the boaters. Consequently upon the stoppage of the machine the material in the machine will be caught by the outer edges of the disks K" and held suspended thereon until the machine starts again, so that no waste oecurs by unseparated material passing through the machine.

Perpendicular reels possess many advantages over horizontal reels; but as heretofore constructed great annoyance is caused by the material that happens to be in the machine at the time it is stopped falling into the hopper with the tailings and being lost, or necessitating the shutting off the supply and running the machine until the material in the machine is separated; but by my arrangement these objections are removed.

I11 the horizontal reel only that portion of the reel that for the time being is running below the center or shaft of the reel is in actual use, while in horizontal reels all the cloth on all sides is in constant use; hence the capacity of the machine is greatly increased.

Having described my invention and set forth its merits, what I claim is 1. In a perpendicular flour-dressing machine, the combination of a slowly-revolving bolting-reel provided with inwardly-inclined rings E E E and vertical internal ribs a a, and a rapidlyrevolviug beater moving in the same direction as the bolting-reel, and provided with ring-sections H IP H, beaterblades 1) b, and horizontal disks K K K, substantially as and for the purpose herein speci fied.

2. In a perpendicular flour-dressing machine, the combination of the revolving boltingrecl, constructed with the inwardly-inclined rings ll E" 1i and vertical ribs a a, the beater-shaft, the beater-rings .11 H H inclined beater-blades b b, and horizontal disks K K K, substantially as and for the purpose herein specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH M. SCIIUTZ.
