Application. filed June ,11, 1926, Serial No. 115,180, and in Great Britain' March w, 1926.
This invention relates to improvements'in single roll wet mills and the like for grinding paint, wet mixed pigments,inks and other allied materials and relates to that-type in which theroller has-axial reciprocation and" in which a grinding bar o'rblock circumfer' entially contacting with said roller is adj ustably mounted in relation thereto. Heretofore in machines of this type it has been necessary to keep a mill for each colour or shade of colour, or, alternatively, to remove a large portion of th ehopper and roller housin'gs toclean down, the reassembly necessitating skilled labour since the roller must be aligned and the housing and hopper adjusted to prevent loss of materials passing out endwise or escaping through the block 'due'to faulty setting; Further, owing to wear'on the grinding blocks beinga'ccentuated over its surface intermediate the ends, adj ustmenton resetting must be exact to former position otherwise the operative surface of the block ceases to contact with-the roller, or contacts at one side only, and the machine in such condition is useless for its purpose. Now according to the present invention th mill not only retains its feature of reciprocating roller and adjustable grinding block but the hopper and feed throat are made removably hinged whereby the roller and housing surfaces can besponged cleanand the grinding block surface so adjusted that skilled setting is unnecessary and the attendant sin gle-handed can clean, refix and adj ustv for fresh material.
Reference will now be made to the accompanying drawings which illustrate by way of example a grinding mill constructed accord ing to the invention and-in which Figure 1 is a side elevation,
Figure 2 is an end elevation,
Figure3 is a crosssectional elevation and Figure 1 is a detail View showing the operative surface of the grinding block.
In the form illustrated a hopper 1 is secured to a throat 2 through which the material to be ground is fedonto the surface of a roller 3. The throat 2 and hopper 1 are carried in a frame 4 carried at one side of the machine on a hinge spindle 5 atone end of which, is mounted a worm wheel 6 meshing with a worm 7 on a spindle 8 carrying a wheel 9 for manual operation. The frame l is normally secured in the operative position shown in the drawings by means of eye bolts 10, the lower hinge spindle 5.

Inorderto counterbalance the frame 45 wheninits raised positionitis preferred to providea weight 50 suspended from an armr filkeyed to the I Torender the throat 2 and hopper 1 capable of adjustmenttowards or from the surface 1 of the rollerf, independently of the hinge movement they are;,mounted'=in the frame members L by means-of lateral extensions-l4 1 Formed integral with the throat 2 and hopper 1 is a housing .19 for a grinding block or bar 20 which is secured in position inthe housing by means of wing nuts 21. Extending across the machine above the said grinding block housing is a cross bar 22 secured to the frame members 11-bywing nuts 23. Through the cross bar pass bolts 24; and 25, the former carrying wing nuts 26 bearing upon springs 27 by varying the compression of which the pressure on the grinding block can be varied. The bolts 25 have" milled heads 28 formed thereon and also means for adjusting the position of the latter. The working face of the grinding block is shown in Figure 4:, the lines A and B indicatlng the mld position of the reciprocating bear upon the grinding block constituting I llll) roller 3. The ends 29 of the grinding block I are of enlarged area but have their central portions removed so] that at those points where'only half the wear is experienced compared with the central portion of the bar, the surface isicorrespondingly reduced.
The roller 3 is mounted on a shaft 30 hav- 2 V W 1,713,270 r V ing at one end fast and loose pulleys 31 and 32 and is reciprocated on its shaft by means of a cam grooved pulley 33 engaging a coned roller 34 the spindle of which is carried in a bracket 35 secured to one of themain frame members 11 and having set screws 36 and 37 to adjust the position of the roller34 to-take up wear. the grinding block 20-the roller 3 may be adjusted in relation thereto. To achieve this, the roller shaft 30 is mounted in adjustable bearings 38 in the frame members 11. Hence 7 should the wear on the grinding block due to inequality of material be experienced the roller can be adjusted in relation'to the block rather than'the block to the roller.
At the front of themill a collecting box 40 is provided the base of which is constituted by a scraper blade 41 closely engaging. the surface of the roller 3 under the influence of springs 42 connected at their upper ends to the ends of the scraper blade and at their lower ends to arms 43 extending inwardly from the frame members 11. The collecting box 40 is also supported on arod 44 extending across the mill between brackets 45 on the frame members 11, the said scraper blade having a slotted lug or lugs 46 on its under side which engage over the rod 44. The collecting box is also provided with an outlet 47, which. as shown comprises an arcuateportion over which a similarly constructed door is movable. 7
Should undue wear take place on V For ordinary viscous bodies the setting of the throat 2in relation to the roller 3 may be coarse, but when dealing with enamel dissolved in spirit it is frequently necessary to cooled as temperature largely alfects the wet vehicle which holds the material in solution or suspension and the degree of viscosity or otherwise determines theiineness of grinding and the value of the resultant product.
