PULVERIZING MACHINE Filed July 1, 1931 2 Sheets-Sheet 2 Patented Nov. 1, 1932 tum-mt STATES PETER V. J'ALI, F PORTLAN DaOBEGON ZEULVERIZING MACHINE y Application filed July 1,

, An object of this invention is to provide an improved pulverizing mill or mechanism by means of which various kinds of material may be fed into the mill at the desired rate of speed.

A further object of this invention is to provide an improved pulverizing mechanism by means of which the pulverizing wheel is rotatably mounted within the housing so that the material may be fed into the housing from one side thereof.

A still further object of this invention is to provide a chute which may be mounted on a pulverizing mechanism of this kind, the chute embodying means for feeding a predetermined quantity of material into the pulverizing mechanism.

The above and various other objects and advantages of this invention will in part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawings, wherein Figure 1 is a detail side elevation partly broken away of a device constructed accord ing to the preferred embodiment of this invention;

Figure 2 is a fragmentary sectional view partly in detail taken on the line 22 of Figure 1;

Figure 3 is a sectional view taken on the line 33 of Figure 1;

Figure 4 is a fragmentary longitudinal section taken substantially through the loni gitudinal center of the chute, and

mounted on the upper ends thereof. A pulley 15 is mounted on the shaft 12 intermediate the standards 14 and a flexible member in the form of a belt or the like, may be trained over this pulley 15, so as to rotate the pulverizing member 11. This housing 10 is provided with an intake port 16 at one side thereof and substantially concentrically of the shaft 12 and disposed about this intake port 16 is positioned a frusto-conical intake spout'17 which has a flange 18 secured to the side wall ofthe housing 10 by means of bolts 19 or the like. i I An elongated chute, generally designated as 20, is secured to the spout 17 and extends at an upward inclination therefrom, the inner end portion 21 of the chute being curved so as to substantially conform to the configuration of the frusto-conical spout 17, and the outer end of the. chute 20 is bent in substantially U-shaped form, as disclosed in Fig ure 3, having a fiat bottom 22 and vertically disposed side members 23. This chute 20 is securely held in upwardly inclined position by means of a pair of bracing members 24, which are preferably of channel or angular construction, being secured at one end to the housing 10 by means of bolts 25 and secured to the chute 20 by means of bolts 26 or the like. The material which it is desired to pulverize or grind in the housing 10 is fed into'the housing by means of the chute 20, and in order to control the amount of material passing downwardly within the chute 20, I have provided a closure member, gener- 'ally designated as 27 which is hinged, as at 28, to the spout or intake member 17.

This closure member 27 comprises an upper plate 29 which is hinged to'the intake member 17 and a lower plate 30 which is pivotally 9 secured adjacent one edge thereof to the upper plate 19 by means of a pivotal member 31. These plate members 29 and 30 are constructed substantially in the form of a semicircular plate which overlap each other at the abutting edges thereof, and the lower plate 30 is provided with a segmental slot 32 for receiving a bolt 33 which is carried by the upper plate 29, and a thumb nut 34 is threadably mounted on the bolt 33 and is adapted V prisi to hold the lower plate 30 in vertically adjusted position with respect to the upper plate 29. a

When the lower plate 30 is lowered, the peripheral edge thereof is adapted to enga the inner surface of the lower end of t e chute v2f.) se as to close this opening and prevent the passage of material into the housi from the chute 20. As disclosed in dotte lines in Figure 2, the lower plate may be raised upwardly so as to permit material to pass therebeneath and into the housing 10, or if desired, the entire closure 27 maybe swung upwardly on the hinge 28 so as not to impede the passage of the material, such as he straw or the like passing downwar y throu h the chute 29 and the intake member 17. #J. 's upper plate 29. is provided with a plurality of apertures therethsrough, so as to permlt the entrance of air or the like into thehousing and to prevent the formation of a vacuum within the housing 10 as the materialrnasses through the intake port 16.

IILthe operation of this device, the pull l5 and the shaft 12 are adapted to be rotate from a conventional power member so as to rotate the pulverizing member 11,rthe operation of which is more specifically described in my prior patent hereinbefore referred to. The closure 27 may be opened to the desired degree, depending upon the character of the material which it is desired to pulverize.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of invention without departin from the spirit thereof, such chan es an modifica- I tions being restricted only hy the scope of the following claims.

I claim I 1. In a pulverizin means, a frustro-conical intake member, an a closure engaging the outer end 05 the member, said closure coman upper rtion swingable outwardly of e outer en of the member, and a lowor portion swingable transversely of the outer end of the member.

2. In a pulverizing means, an intake member, a closure for said member and hinge means forhinging the closure to the member for upward swinging movement, said closure comprising an upper plate, a lower plate, a pivot for securing the lower plate to the per plate for vertical swinging movement in a plane parallel to the outer surface of the upperflate, and means engaging each plate to hol the lower plate in ad usted osltion.

3. In a pulverizing means, an inta e memcenter thereof, one of said plates having an arcuate slot therein, and a thumb bolt carried by the other plate and extendin through the slot whereby to permit vertica adjustment of the lower plate relative to the upper plate.

. In testimony whereof I hereunto afilx my PETER V. JALI.

I ber, a closure for saidmember, hinge means for hiuging the closure to the member for upward swinging movement, said closure comprising an upper plate hinged to the intake member, a lower plate, a pivot enga ing the upper and lower plates at one side 0 the
