FLOUR-MACI-IINE.

Specification of Letters Patent.

Patented Feb. 9, 1909.

Application led July 31, 1908. Serial No2 446,308.

To all 'whom it may concern:

Be it known that we, SAMUEL L. SNYDER,

and SYLvEsTER JACKLIN, citizens of the United States, residing at Holgate, in the county of Henry and State of Ohio, have invented certain new and Vuseful Improvements in Flour-Machines, of which the following is a specication.

This invention relates to flour milling machinery, and has particular reference to machines designed for the purposes of bolting, sifting, scouring, cleaning, scalping, and the like, in flour mills, and may be utilized in other connections such as in separation generally. f

For a full understanding of the invention, reference is to be had to the following detail description and tothe accompanying drawings, in which- Figure 1 is a vertical sectional view of the invention as used as a bolting machine; Fig. 2 is a similar view showing the invention applied as a scourer, and including a slightly modified form of operating disk; Fig. 3 is a detail illustrating the relative positions of the inlet spout and vertical drive shaft; Fig. 4 is an enlarged detail of one of the disks showing one of the ways in which the same may be attached to the drive shaft, and Fig.

5 is a plan view of one of the parts shown in Fig. 1.

Throughout the following detail description and on the several ligures of the drawings similar parts are referred to by like reference characters.

The machine constituting the subject of this invention comprises anylsuitable form of substantial frame 10 which may be portable or stationary, as may be desired in any particular case. Secured in any suitable manner within said frame is a casing 11- which may be of any suitable form in cross section, either polygonal orcircular. Within the casing 11 is a separating screen 12, preferably cylindrical in form. The casing 11 it will be understood is stationary with respect to the frame 10 which supports it. Likewise, the separating screen 12 is mounted in a stationary relation to the outer casing 11. To this end the screen may bemounted upon a skeleton frame comprising upper and lower disks 14 and 15 and connecting ribs 16.

A power shaft 17 extends vertically vand centrally through the aforesaid frame and casing and is mounted at its lower end 1n Vany suitablel form of step bearing 18,

mounted preferably upon the lower portion of the frame 10 of the machine. Said shaft 17 will have bearings in the aforesaid disks 14- and 15, as well as in a bearing at the top of the frame 10. This shaft will be driven in any suitable manner by a power pulley 19 located at any convenient point in the shaft. Mounted upon the shaft within the casing 12 are a plurality of disks 20, shown in Fig. 1 as being flat and circular. These disks-may be secured to the shaft in any suitable or convenient manner. As an illustration of such means there are shown the following devices: A collar 21 is secured rigidly as by set screw 22 to the shaft so as todetermine the elevation of the disk. The disk surrounds the shaft in proximity to the upper surface of the collar, and the circular plate 23 surrounds the shaft immediately below the collar. The disk and plate 23 may be connected by means of adjustable fastenings 211 in such a manner as to make a frictional connection between the disk and the collar. ln some instances it may be highly desirable to provide such connection for the disks. as to permit relative movement between the disk and the shaft, as for instance when an obstacle such as a stone is fed into the machine. Vith a connection such as indicated an obstacle might cause the disk to remain stationary while the shaft continues to. rotate without doing any serious damage tothe machine. 1t. will be understood, however, that the friction between the disk and the collar will be sufficient to operate the disk from the shaft under ordinary conditions of service. Each disk and its plate 23 being clamped to the collar 21 in accordance with the desired frictional tension, in order to vary the adjustment of the disk on the shaft 17 it is only necessary to loosen the set screw 22. The said screw is freely accessible from the space between the disk and plate, and the manipulation thereof to raise or lower the disk, as is desirable in machines of this character, may be effected without altering the said connection with the collar. i

Located beneath the .uppermost disk 20 and secured preferably to the uprights or ribs 16 is a funnel or hopper 25, which may be provided with a vertical flange 2G if desired. is indicated in the drawings one of the hoppers or funnels 25 will be located directly beneath each of the disks 20. ln other words, the disks and hoppers will alternate throughout the extent of the niachine. rllhe diameter of the disk 2O is less than the'internal diameter of the screen 12, while that of the funnels 25 is substantially equal thereto. The funnels 25- being connected to the rigid members of the casing' are stationary, and are provided at their lower ends or apexes each with an opening,- 27, directly above the center of the disk next below. The material to be operated upon may be fed into the top of the machine in any convenient mann .r but preferably by a spout Q8 which as indicated directs the material upon opposite sides of the shaft 1T, whereby the material separated so as to cause different portions thereof te' be acted upon by different portions of the disk at the same time. By this means the output of the machine may be materially greater than if the spout directed the vmaterial all to one spot. yllhe disks are provided with propelling blades 20 on their upper surfaces, which acting` upon the material will throw the same due to the rotary movement of the disks against the screen it portion of the material will pass through the screen and another portion thereof will drop into the funnel 25 immediately below the first disk. From this funnel material will be directed upon the second disk, which will act upon it in a manner similar to that first described, a portion again of the material passing through the screen and the eoarser portions rolling` down upon and through the second funnel, and so on throughout the whole machine. rlrhe first grade material, that which passes directly through the screen 12 will be received at the bottom of the casing between the screen and the casing 11, and will be delivered therefrom through a spout 29 through the operation of a scraper 30 secured to the shaft 17 and rotating` there with. The second grade material, that portion which does not pass through the screen directly may be directed from the top of the lower disk 15, by operation of a scraper 81, and thence directed downwardly through a spout 82 to any convenient point. As illustrated in Fig. 1 said spout 32 leads to another spout 33 into the top of a second screen section7 the screen of which may be of a different mesh if desired from that of the first, and in which the material will be again acted upon as before, that portion of the material which passes through the screen being in all cases of a liner grade than that which does not so pass through. 1n this form of machine the second grade material is drawn therefrom at the bottom through a.

spout 34, and the coarsest grade will be received through a spout 35 from the interior of the screen at the lower end.

1n tle form of the machine, used as a` scourer or cleaner, illustrated in Figi. 2, it. may be desirable to employ a suction fan 3h located at any convenient point, as at the top of the machine. As in the former modiiication the separating screen is stationary within the stationary frame. A similar form of funnels is employed, and as before a plurality of disks are secured upon the vertical central shaft for rotation between the funnels. ln this figure a slightly modilied form of disks is illustrated, although it will be understood that the form of the disks is not dependent upon any particular type of machine or operation to be carried thereby. s shown herein the disks Q0 are funnel-shaped, or conical, and it will be understood that the centrifugal force given the machine through the lshaft will be su'l'licient in all forms of the invention lo propel material outwardly against the screen 12.

ln the operation of scouringv or cleaning` it is desirable to connect the fan chamber by means of conduits 3T with each of the several chambers between the stationary funnels, whereby dust or light particles of matter may be withdrawn therefrom and blown away to any convenient place by operation of the tan 2b. The principle of the separation is the same in both forms of the invention illustrated. .it will be understood that the apparatus may be constructed of any suitable materials or proportionate parts and that slight modilications may be resorted to within the spirit of the invention hereinafter claimed.

Having thus described the invention, what is claimed as new, is:

1. ln a machine of the character set forth, the combination of an outer easing, an inner casing' providingv a stationary screen, a central rotary power shaft within said screen, a series of funnels fixed upon the inner vall of said screen, a series of disks, one disk above each funnel, and means to adjustably secure each disk to the power shaft, such securing means comprising' a collar, means to frictionally secure the disk to the collar, and means operable imlependently of said frictional securing' means to lix the collar at the desired distance from the adjacent funnel.
