DISK FEEDER.
Application filed June is, 192.5. semi m. 38,230.
This invention relates to apparatus for receiving coal or similar comparatively coarse material from any source of en ply and feeding the same at an even rate speed to ,5 any apparatus such as a pulverizingmachme or the like; and the object of the 1m rovement'is to provide an apparatus 1nclu mg a hopper bin or spout arranged to receive the coal or other material to be fed, an upright stationary cylinder communicating with the lower end of the hopper and having an outlet opening arranged to be controlled b a rotatable sleeve valve, a rotary feeding sk being mounted directly beneath said cylinder and eccentric thereto and ada ted to receive the coal which passes throng said out:
let opening, a scraper blade extending across said disk at oneside of the outlet opening for the purpose of scraping the coal from '20 the disk and feeding it in an even stream to a chute, conveyor or receptacle of any usual design. An embodiment of the invention is. illustrated in the accompanying drawings, in which--- i Figure 1,is a side elevation partly n section of the improved feeding machine' Fig. 2, an enlarged vertical sectiona view through the same taken substantially on the line 2-2, Fig. 3; s

of the rotatable sleeve valve;
Fig. 5, a plan view of the same; Fig. 6, a side elevation with part broken awa of the stationary cylindrical spout;
F1 7, a fragmentary pers ective view showing the rotatable sleeve va ve in closed position;
Fig. 8, a similar view showing the valve slightly opened; I
Fig. 9, a view showing the valve substantially one-half open;
Fig. 10, a view showing the valve substantially three-fourths open;
Fig. 11, a view showing the valve fully open, and A Fig. 12, a similar view showing an adjusting plate provided for accommodating ver fine material. S imilar numerals of reference indicate spaced from the disk just sufliciently to percorresponding parts throughout the draw- A base frame 1 may be provided with the' per end the rotary feeding dlsk 4 provided on its under side with a bevel gear 5 meshmg with a bevel pinion 6 upon the drive bearings 8 provided; upon the base and driven from any suitable source of supply as through the gear 9 meshing with a lIlIOIl shaft 7--which is journaled in horizontal 10 upon the counter shaft 11 provide with p the drive sprocket 12.
A super structure 13 may extend above the base and supports the stationary cylindric spout 14 eccentric to the feeding disk 4. The lower end, of this cylindric spout is mit free rotation of the disk without rictional engagement with the spout, and one side of the spout is cut away as shown at 15, forming an arcuate outlet 0 ening from the spout .onto the feeding dis Adjacent to one side of said opening and substantially tangential to the spout is located a scra er bla e 16 rigidly supported as by the brac et 17 fixed to the cylindric spout. v
A wiper 18 which may be of leather or other flexible material is connectedvto the inner end of the scraper blade as by the plate 19 and cap screws 20 and extends into the outlet opening 15 and contacts with the valve 21.
This valve is cylindrical and rotates freely within the spout 14 and is rovided with an arcuate 1port 22 of substant1ally the size and shape 0' the outlet ofening 15 in the spout.
For the purpose 0 worm gear 23 maybe provided around the upper peripheral edge thereof and extended into an annular channel guide bearing 24. A worm 25, mounted upon the valve operating shaft 26, meshes with saidworm gear and may be provided with a hand wheel 27 for manually rotating the valve within the spout 1 A hopper 28 may be provided above and communicating with the cylindri'cspout, to receive the coal or other material to be fed through the apparatus.
For the purpose of continually agitating adjusting the valve, a-
the material within the hopper, to prevent clogging of the same, the shaft 3 may be continued upward through the cylindrical spout and hop er as indicated at 29 and provlded with ra ial agitating arms 30.
By rotating the sleeve valve 21, within the cylindric spout, the outlet opening 15 in the spout may be entirely out ofi as shown in Fig. 7, or the valve may be set at any de sired position between the fully'closed position and the fully open position shown in Fig. 11, as illustrated in Figs. 8, 9 and 10, thus permitting any desired amount of the coal to be continually fed from the spout onto the feeding disk.
This disk is continuously slowly rotated in the direction of the arrows shown in these figures, the coal being immediately carried away from the outlet opening as it passes through the same, owing to the eccentric position of the disk wit reference to the spout, thus continually clearing the outlet opening and preventing clogging of the material at this point.
As the disk rotates the material received thereon through the outlet opening of the spout is carried against the sore er blade 16 and fed over the peripheral e ge of the disk adjacent to the scraper blade as illustrated in Figs. 9, to 11, a chute, convyor or other receivin device being of course arranged in position, beneath this point, to receive the coal in a steady stream as it is fed from the disk. I
It should be understood that this feeding disk is rotated at a speed considerably less than that which would develop centrifugal force which would tend to throw the material outward u on the disk or over the peripheral edge thereof. In actual practice the speed of this disk is preferably from one to ten revolutions er minute, depending upon the quality an grade of material being fed through the machine, and also upon the rate of feed of the same.
In Fig. 12 is V illustrated an adjusting plate 31 which may be detachably secured to the spout as by screws or bolts 32 covering a portion of the outlet opening of the spout and provided with an inclined lower edge 33 forming a reduced outlet opening especially designed for use upon very fine material as shown in said figure.
I claim:
1. A feeding apparatus including a cylindric spout having a side outlet openin in its lower peripheral ortion, a movable feeding disk beneath t e spout for receiving material from the same, and a scraper blade tangential to said spout co-operatlng with the movable disk to feed material over the edge of the same.
2. A feeding apparatus including a cylindric spout having a side outlet opening in its lower peripheral portion, an eccentric feeding disk beneath the spout and a scraper blade tangential to said spout co-operatmg therewith.
In testimony that I claim the above, I have hereunto subscribed my name.
