MIDDLINGS-PURIFIEIR.
SPECIFICATION forming part of Letters Patent No. 400,538, dated April 2, 1889. Application filed February 15, 1888. Serial No. 264,098. on model.)
To all lull/01w it may concern.-
Be it known that I, GEORGE W. BELL, of River Falls, in the county of Pierce and State of Wisconsin, have invented a new and Improved Middlings-Purifier, of which the following is a full, clear, and exact description.
The object of this invention is to provide for the purification of middlings or flour by means of currents of air, the invention consisting in the construction and arrangement of parts, as will be hereinafter more fully described, and specifically pointed out, in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.
Figure 1 is a side view of my improved mid- I dlings-purifier, a portion of the outer case being broken away. Fig. 2 is a plan view of the same in partial section on line' a: a: of Fig. 1. Fig. 3 is a central sectional elevation of the apparatus; and Fig. 4 is a sectional plan view taken on line y y of Fig. 3.
In the drawings, represents the main frame-of the apparatus, which serves as the fsupport for a flooring, 11. In the center of this flooring 11 there is an aperture, 12, through which there is passed a central vertical shaft, 13, that is stepped at 14 and guided at its upper end by proper bearings, as shown in Fig. 3. To this shaft 13 there is connected a lower perforated disk, 15, and three or more upper disks, 16, 17, and 18, the disks 16 and 17 being perforated in close proximity to the shaft and the upper disk being imperforate. Between the disks I mount perforated cylinders 19, 20, and 21, the cylinder 19 being more profusely perforated and the cylinder 21 less than the cylinder 20. I
In a position concentric with that 'of the cylinder 19 I mount an outer cylinder," 22, having perforations 23, which cylinder 22 is concentric with the axis of the shaft 13 and rests directly upon the floor 11. Upon the top of the cylinder 22 there is seated a flanged ring or hoop, 25, which serves as the support for a cylinder, 26, formed with apertures 27, and this ring 25 also serves as the support for a hopper, 28. A second ring, 25, is supported by the cylinder 26, and this ring supports an upper cylinder, 30, having apertures 30 and a hopper, 31. the inner cover, 32, which cover is formed with a circular line of apertures, 33, and above the cover 32 there is mounted an outer cover, 34, formed with two or more apertures, 35. The structure made up of the cylinders 22, 26, and 30 and the parts contained therein is inclosed by an outer cylinder, 36, which rests upon the floor 11 and abuts against the inner cover, 32, this cylinder being provided with a slide-door, 37, as best shown in Fig. 3.
The shaft 13 carriesa bevel-gear, 39, that is engaged by a corresponding gear, 40, carried by a horizontal shaft, 41, which shaft 41. carries a pulley, 42, which, when the apparatus is in operation, is driven by means of a belt passing from the counter-shaft. In addition to the pulley 42,,the shaft 41 carries a pulley, 44, about which there is passed a belt, 45,"that runs in engagement with a pulley, 46, carried by the shaft 47 of a fan, 48, that is mounted in any proper position, preferably at the side of the frame, as shown in the construction illustrated in the drawings. The current generated by the fan 48 is forced through a passage, 50, to pass thence through the opening 12 in the floor 11, and through the apertures 2 of the disk 15, thence in the direct-ion of the arrows, to finally pass outward through the apertures 35 of the cover 34. The cover 34 is centrally apertured, and in the aperture so formed there is fitted a tube, 51, which leads downward through a central aperture formed in the cover 32. This tube 51 is provided for the reception of a 'hopper, into which the material to be acted upon is to be delivered upon a disk, 13, on the end of shaft 13, to pass thence downward and onto the disk 18, which, when the apparatus is in operation, will be rapidly revolved, owing to the rotary motion imparted to the shaft 13 through the medium of its connections with the driving-shaft 41. As the disk 18 is thus rapidly revolved, the material delivered thereto will be carried to the edge of the disk and into the hopper 31 by centrifugal force, being subjected to a current of air passing from the apertures 3 of the cylinder 21 as it falls over the edge of the disk.
The cylinder 30 abuts against the disk 17, to be thence thrown out and into the hopper 28 downward to the disk 16, then outward and onto the floor 11, having at all times in its descent been subjected to the action of the currents of air issuing from the perforations formed in the cylinders 19, 20, and 21. After falling upon the floor 11 the material is gathered by a scraper, 60, that is connected to the cylinder 19, and carried forward to an opening, 61,1:hrough which it falls into any proper form of conveyer.
In order that the dust and woody fiber blown through perforations 23 27 may not fill the space between the cylinders 22, 26, and 30, I provide an endless band, (32, which is formed with ontwardly-extendin g projections 63, the band resting closely against the peripheral face of the cylinder 22.
The under edge of the band 62 is formed with gear-teeth, as indicated by dotted lines in Fig. 3, and these teeth are engaged by a small gear or pinion, (31, which is carried by a short shaft, 65, upon the outer end of which shaft there is a gear, 66, that meshes with a pinion, (57, carried by the shaft 4.1, the arran gement being such that when the machine is in operation the band will be continually advanced and all material deposited in the space above referred to will be carried forward to the opening 68, through which the pinion 61 extends, to be carried thence by any proper convcyer to a dust-receptacle.
In order that the woody fiber of the wheat may be prevented from lodging against the side walls of the outer cylinder, 36, and the inner cylinders, 22, 26, and 30, I mount a crankshaft, 69, at one side of the machine, this shaft being provided with an upwardly-extending hammerarm, 70, which is normally held against a plug, 71, by the action of a spring, 7 2, which bears against the crank of the shaft 6.), the inner end of the plug 71 resting against the ring 25, or against any other proper point of the inner series of cylinders.
The shaft 69 is provided with an arm, 73, which extends to a point beyond the peripheral face of the gear (so and into the path of a pin or stud, 71, carried by said gear, so that at every revolution of the gear the arm 7 3 will be thrown upward against the tension of the spring 72, and the hammer-like arm will be thrown against the plug 71, thus jarring the outer and inner cylinders of the apparatus.
From the above description it will be seen that all finer particles of dust will be carried upward and out of the apparatus, passing through the apertures 33 and 35, while the heavier particles of dust will fall into the space between the cylinders 36 and the cylinders 22, 26, and 30, to be delivered thence by the scraper composed of the ring 62, having the projection 63.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A middlings purifier comprising the frame, the flooring 11, having openings 12, (i1, and 65, the ring 15 around the opening 12, the vertical shaft 13, j ournaled in the frame, passing through said ring, and provided with the vertically-apertured disks 16 17 18, the series of apertured cylinders 19 2O 21 between said disks, the apertures increasing in number from the top cylinder downward, a blower delivering upwardly through the ring 15, the outer series of perforated cylinders having separating-rings and apertures also increasing in number from the top to the bottom cylinder, the downwardly and inwardly tapering hoppers supported by said rings and of greater diameter at their upper ends than the said disks surrounding casing 36, the cover 32, having openings between the said casing 36 and the top cylinder, 30, upper cover, 34, having apertures 35, and the delivery-tube 51, extending through said covers to deliver upon the disk 18, substantially as set forth.
2. The combination, with a middlings-purifier of the character described, of a crankshaft, (59, having an upwardly-projectin g hammer-arm at one end and an operating-arm, 73, at its opposite end, a plate-spring, 72, bearing on said crank, and a Wheel having a pin into the path of which said arm 73 projects, substantially as set forth.
