IMPROVEMENT IN PAINT-MILLS.

itinA Stimuli referat tu iml tipa ttias 33mm :mh mating pat ai tige time.

Be it known that I, CHARLES CLIFTON, of Jersey City, Hudson county, and State of New Jersey, have invented new and useful Improvements in Grinding-Mills; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable .others skilled in the art to make and use the same, reference being' had to the accompanying drawing, forming part of' this specification.

The present invention relates to improvements in mills or machines for the grinding or pulverizing of paints,

ores, or other minerals, and it consists principally of a revolving hollow cylinder tapering from end to end, in

combination with a stationary crusher or grinder, the two being arranged and combined together in an extremely novel and peculiar manner,lwhereby 4an eiiicient and practical grinding-mill is obtained, as will be obvious from the following detail description of ythe same, reference being had' to the accompanying plato of drawings, in which V Figure 1 is a horizontal section, taken in the plane of the line :I: w, fig. 2.

Figure 2, a transverse vertical section, taken in the plane of the line y y, fig. 1.

Figure 3, a longitudinal vertical section, taken in the plane of the line z e, fig. 1; and

Figure 4, a detail section, taken in the plane of the line w w, fig. 1.

Similar letters of reference indicate like parts.

A A, in the drawings, represent a hollow cylinder, which .is made of a tapering shapefrom end to end, and closed at each end by head-plates B B. This cylinder is hung upon a central horizontal shaft or axis, C, which extends entirely through the same, projecting from each end or head, and -at such projecting end is `supported en uprights or standards, D, fixed to the bottom or bed-frame E; the body portion of the cylinder resting upon friction-rollers, F, hung upon the upper side of the bed-frame E. Around the cylinder A, at or near its smaller end, a toothed or gear-ringer collar, G, is secured, with which interlocks a vertical gear-wheel, H, of a horizontal shaft I, arranged to turn in suitable bearings of the uprights of the bed-frame E. K, a pulley secured to one end of shaft I, to which pulley the driving power employed is to be connected. The portion'of the-shaft,

C, embraced between the two cylinder heads, B, is made of a square'shape, with pieces, L, projecting from each side of its two sides, and at corresponding points, through which pieces extend downward projecting squareshaped arms M, that are secured in position by means of nuts, N, screwed upon their upper ends. Between these posts or arms M, and extending from one end ofthe cylinder to the other, the grinderfweight, O. is placed,

resting upon the bottom of the cylinder, and playing up and down in the same between the said posts, M,which act as guides to such movement. This weight, O, is open from end to end, or made of a boxfshape, with its two ends open, so as to receive a series of plates, P, which are laid one upon another, the number of which is to `depend upon the weight desired for the grinder. On the upper side of the cylinder-shaft, C, a rocker frame, Q, is suspended in suitable bearings at each end, to which frame a scrapereblade, Be, is secured by screw bolts and nuts, or in any other proper manner, so that its edge, S, will bear against the interior surface of, the cylinder A. This frame, carrying the scraper R, has a weight, T, affixed to its arm U, projecting from the opposite side of the same to that at` which the scraper-blade is secured, as explained; the object of this weight being ,to hold the scraper' to its work or bearing upon the cylinder, for the more perfect accomplishment of which the weight A is susceptible of adjustment upon the arm U, so as to produce more o r less pressure upon the scraper-blade, according as may he desired. Through the end of the shaft C, at the smaller end of the cylinder, a hole m: passage, a, is bored in .the direction of its length, with the inner end Aof which bore commnnicates a bent tubo, b extending downward from the said shaft to a point near the bottom of the cylinder. In the bore, c, is inserted tube c, which projects therefrom at its outer end, and at such end is secured in the support ci, upon .thetop of' the upright D, supporting such .end o f the shaft C. In this tube a spiral or screw-shaped shaft, W, is arranoed so as to turn, which screw-shaft., at its inner end, extends over the connecting pipe of tube, ,1), of the inside of the cylinder, and at its outer end has a pinion or gearfwheel, X, secured to it, which meshes or intorlocks with another pinion or gear-wheel, Y, 'upon .one end ,of a horizontal shaft, @connected through a gear-wheel, A?, upon its other end, with the gear'wheel or collar, B, upon the smaller ,end ,of the cylinder To .the tube q, in which the screw-shaft revolves, and at or near its outer end, a hopper, C2, is connected, between which the said shaft communication is had through the open bottom, D2, of the same. In this open bottom a slide, E2, is arranged for closing or opening the-same, at pleasure; mld 11b00 the Said open bottom a sieve .or perforated plate, F2, is used to regulate the size of the particles `of material passing to the said screw-shaft. G2, a passage through end of 'shaft C, having the screw arranged in it ab above described, with the inner end of which passage a bent pipe or tube, H2, is connected, thatextends downward to a point near the bottom of the cylinder A. I2, a pipe or tube extending from a point near the bottom of the larger end of the cylinder, A, to the centre-shaft, C, at suchend, with a passage, I2, of which it communicates at its inner cud; this passage, extending through the shaft, in the direction of its length, to the outer end, J2, of the samegwhere it terminates in a shorttube or pipe L2.

Having thus in detail described the construction and arrangement of the various parts composing my improved grinding-mill, I will now proceed to explain the manner in which it operates.

The paint or other material which is to be ground or pulverized is placed'in the hopper C2, from which, passing down through the screen or sieve, F2, and its open bottom D', it enters the tube, c, in which the screwshaft, W, is arranged, through which it is carried by its inotion or revolution,and forced down through the tube, b into the bottom of the cylinder. v In this cylinder it is acted upon by the grinder or pulverizcr, O, between it and the cylinder, the grinder rcmainingstationary while the cylinder revolves, and is thus ground or pulverized, at the same time gradually working toward the larger end of the cylinder, owingnto its taper form, from which, by means of a suction or other suitable pump, or other proper implement connected with the outer end of the tube, L2, at such end of the cylinder-shaft, it is drawn up through the same, and discharged from the cylinder. In case it 'is necessary to supply water or other suitable moistening liquid to the mineral being ground in the cylinder A, it is forced into the same through the tube or passage H2, hereinbefore referred to, and bythe action of the scraper-blade upon the interior surface of the cylinder, the contents of the cylinder are prevented from adhering to the same, but are, on the contrary, caused to be constantly scraped or rem'ovcd therefrom as the cylinder revolves, and thus always subjected to the action of the grinder or pulverizer. In tig. 2 a supplementary scraper, A4, is shown. Thisscraper is hung vto one of the legs, M, of the grinder, at that end of the cylinder having the discharge-pipe I2, forthe material ground in it. This scraper also bear-s against the inside of the cylinder, where it is held'byA weighting it, or in any other suitable manner, it being arranged to so bear upon the cylinder as to hold the material 'ground in the cylinder downto Athe discharge-pipe, I2, for being pumped through the same, or otherwise removed from the cylinder.

I claim as new, and desire to secure by Leters Patent- 1. The .cylinder A, in combination with the grinder or pulverizer, O, when arranged together and operating substantially as 'and ferithe purpose described.

2'. ',Ihe grinder` or pulverizer O, when made hollow, substantially as and for the purpose described.

3. The spiral screw-shaft or lconvey/ er W, or its equivalent, when arranged within the stationary centreshaft, C, on which the cylinder A revolves or turns, vsubstantially as described, for the purpose specified.

4. Removing the material ground in the cylinder, A, from the same through a pipe or tube, I, arranged or formed within the centre and stationary shaft C, so as to form a communication between the inside and outside of the cylinder.`
