2 Claims.

This "invention relates to a rodmill for crushing, pulverizing or mixing materials, such as dye, face powder, or the like, and is a division of my co-pen-dlng application, Serial No. 424,839, filed December 29, 1941, for Rodmlll now Patent Number 2,367,585, dated January 16, 1945.

An object or this invention is to provid in a pulverizing mill an improved means whereby the ground material ma be selectively discharged therefrom during the rotation of the mill.

Another object 01 this invention is to provide in .a pulverlzlng mill or this kind, an improved means whereby the ground material may be removed from an end of the mill and retained in a chamber at one end of the mill for rotation with the mill and subsequently discharged from the collecting chamber as the mill rotates.

To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to andlllustrated in the accompanying drawing, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.

Figure 1 shows a side elevation partly in longitudinal section of a pulverizing mill constructed according to an embodiment of this invention,

Figure 2 is an end view of the mill showing the radially disposed housings, and the opposite side walls or the housings. All other details have been omitted, namely the crank handle, the car- 1 riage with its supporting tracks and the base with the rollers.

Referring to Figure 1, the numeral l designates generally a pulverizing mill member which is rotatabl supported on a base structure H. The mill member l0 includes a cylindrical body l2 containing a number of pulverizing units or bars [3. The cylindrical body I! is formed with an opening l4 through which the material is charged for filling the mill. The closure member I5 is adapted to be removably secured to the cylindrical wall l2 for closing the filling opening I4,

A forward end wall I8 is secured to one end 01' the cylindrical body 2 and a rear end wall I! is secured to the opposite end of the cylindrical wall l2. A trunnion I8 is secured to the end wall I 9V and is rotatably supported in a bearing 9 carrled by an upstanding bearing support which offset from the outer walls of the two housings is fixed to the base II and braced by means of one or more bracing members 2|. The cylindria circular track or rail 22, which engages a pair of spaced apart rollers 23 carried by bearing members 24 which are fixed to the base H.

A ring gear 25 is fixed to the outer side of the end wall l6 and is adapted to mesh with a driving pinion 26 carried by a shaft 21. The shaft 21 is connected to a reduction gearing 28 of conventional construction which has connected therewith a driving wheel 29. The driving wheel '29 may be operated in any suitable manner from a power member (not shown).

The end wall H has secured thereto a pair of diametrically opposed and outwardly extending end walls 33, thereby forming a pulverized ma terial receiving chamber 34. The outer end of the housing 30 has an outer end wall which is connected with the walls 33 and with the wall 32, and is outwardly offset from the outer marginal edge of the end wall H. An inwardly extending wall 36 is connected at one end to the forward end of the outer wall 35, and at the other end is fixed to the peripheral surface of the cylindrical body I2 forwardl of the end wall The cylindrical wall or body I2 is formed with an opening 31 communicating with the passage 38 formed by the wall 36, so that when the hous-' ing 30 is in a lowermost position, the pulverized material will flow downwardly through the opening 31 and the passage 38 into the lower portion of the housing 30. The inner portion of the housing '30 is connected to the inner portion of the housing 3| by means of anannular connecting Wall 39 which, as shown in Figure 1, is inwardly all and 3|.

The housing 3| is similar in every detail to the construction of the housing 39, the cylindrical wall l2 being formed with a discharge opening 49 adjacent the end wall which oommunicates with the chamber 4| through a passage 42 simr lar to the passage 38.

End wall I1 is provided with an annular enlargement or boss 63 within which a bearing sleeve 64 engages and the'bearing 64 at its outer or rear end is formed with an annular flange 65 engaging against the outer side of the enlargement or boss 63. A manually operable valve generally designated as 66 is loosely mounted at its inner end in the bearing sleeve 64.

An outer bearing sleeve 61 is carried by the housings 30 and 3|, and the outer end portion of the valve member 66 also rotatably engages
