l A rlhe objectief.the,present,invention is to provider an improved- ,millfor` grindingVK paints, inks, enamels and ,other viscous `materials, of vwhich the construction is simplified and which willfhave a maximum output.
A grinding mill chiefly comprises a grinding roller cooperatinggwith a rectilinear grinding block, and a feed hopper arranged above tlieproller, particular means-being pro,-
1Q vided for regulating the pressure of the grindi ing block. ,y n
An objectief the invention is to provide a articularly strong and reliable mechanism or imparting a. reciprocating movement to l the grinding block, said movement being derived from the rotary movement .of thegrindg ing roller, but beingpreferably not in timed relation'withthe latter movement.
Another object of the invention is to provide in combination with said mechanism for reciprocating the grinding block, a-mechanism for lifting the feed hopper togetherwith j thegrinding block and4 its actuatingl mechanism, for the purpose of allowing the Various parts'of-the machine of being easily cleaned.
According tjo theinVention,` it is possiblev to varythe speed of the-reciprocating movement of the grinding block`v andtherebyy al.- ways to cause the later to move at the speed ,30 requiredfby the material -to lbe treated. a
The invention will be described hereafter withfreference tothe figuresV of they accompanying drawings, ywhich illustrate, merely by wayof example,an embodiment of the invent1on.j Fig. 1 is a side .view of-,the machine, seenv in the directionfofarrow liof-Figk-E?I and showing the means for'lifting the feed hopy L f provided wlth a'longitudinal slot17,in whic per and grinding block; Fig,... 2 is an elevation sectional view of thelefthalfof the machine, alsoshowing the means for liftingthe feed hopper 4and grindinblock.; l l
view throughy the grinding-block, on line view inthedirection of arrow E ofFig. 4,
section through the 1g. 3 1s partly `'a longitudinal sectional` With reference to( these fivures, the mill comprises` a roller `l, slidably lized on a shaft 2`3,'nc1''actuated to have a yrotary movement, for instance by afast and loose pulley device.
Above therolle'r. or cylinder l, is'arranged feed hopper 4and laterally a rectilinear grindingblock The ground material is collected lbya scraper'and directed .j over 'a slo'p e'6.`, Theelementsare supported in a r, frame 7. LThe pressure of the rinding block` o0 on the cylinder is "adjustable, y means of a particular device, which `canbe operated While the machine is lrunning and" which will be described hereafter. Y' Y.
Referring more particularly to Figs?) and 4tlie grinding .device 'comprises an elongated casing 8 of U-shaped cross section andmade yoff-castl iron or any other suitable material. In` this casing is adapted to slide lon-` gitudinally a sliding member 9.` The recipro-` cating movement of thispslide member 9 is obtained .withfa device` comprising cams 10 y `arranged at both endsof the sliding member 9; These ,cams 10 are driven by toothed. wheels 11,' and 1 2 located at both ends of the 7,5 grinding'roller 1. The toothed Wheel 11 brings abouttherotation of shaftlS lon whichis keyed the worin `14, which meshes. with ,the-helically ltoothed wheel 15, mounted on shaft 16upo which is keyedthecam 3. Itwillbeeasily understood that b replacingrthe toothed wheelsll` and 12A y other toothedwheels, it is possible to impart different movements to the worms 14` and the wheels 15,l which,inturn, rotate the .cams 3 at different speeds'-, VIt is thus possible'to reciprocate the :liding member 9Jatfanyrequ1red speed.. The sliding member 9 is 'centrali is accommodated the rectilinear` grindin blockyor bar 5, which'fc'omes in contact wit v the rollerl'.. The grinding'block is held in` its position in contact with the roller 1, v'by means of pressure screws 18, which pass through` the pressurebarlQ, which isitself pressed against the sliding member 9 by pressure nuts 20 arranged at the ends of the slid-,fV ingblock.l The pressure'screws 18,'are .pro-` vided withwinged heads 21 and Amay be locked against rotation byv lock nuts 22.
In order to maintain the grinding block 5 against the smooth face 23 ofthe sliding vmember 9, rollers or idlers 24 have been provided to press againstthe grinding block and they are maintained in this position bypressure screws 25 passing through a slot 26 formed inthe casing,v 8. These slots have va length which is equal or greaterthan the Y stroke of the sliding member 9. 'The pressure screws 25 may be regulated from the outside by means of milled knobs. Recesses or grooves 9 Jmay be provided inthesliding ymember 9 to reduce the friction against the walls of the casing 8. y l
LThe whole combination of hopper and grinding block'with'its sliding member and casing rl`isfmount'edv upon 'lateral supports `27.
The hopper yrests on they lateral supports 27j withfitslugs or lateral 'flanges 28, s acing 'bars29`being interposed. lAsis well nown in the art,'it 1s thuspossible to adjust the'ver-k tical position of the hopperl, so that itcan be placed 'at a desired' distancev fromthe roller. .p The casiii l8 forfthe grinding b1ock`5 is'A provided atlr oth end s with a fiat portion 8 which comes to rest on a fiat k surface of; the lateral" supports 27 and which is secured thereon by four bolts 27. The lateral supports 27 which support the hopper and the grinding block with vits regulating means rest normallyron the uprights 30 of frame 7 and theypcan' be fixed l'n` this position 'bymeans' such as swivellingfbolts 31 with pressure nuts v32.'-1Sucha. connecting device ensures the necessarypressure for the grinding operation r when themachine isru'nning, whil'stfit"y allows-'atthefsame time a lrapid release by unscrewing Athe four nuts'32, whereby, the
. superstructure of the machine is yfreed for the pu'pose 'of'cleaning the various parts of the For this purpose, the upper elements of the machineyvvh'en they are released l from the pressure connection 31-'32,' are liftedv yby meansofa combined construction, which will be now described. i The lateral'supports or bridges 27 are supported by standards or columns 33, which are adapted to slide vertically in'correspondingguide Ways provided on the inner surfaces the lateral uprights 30 of the frame. V`'lhese'guide'tracks will be, for inr stance, dovetailed tenons 34 formed on said inner facejof the uprights 30, on which slide mortises 35 having thesame shape. At theirl n' win be understood-that, by Caring Said shaft 39 by means of an appropriate device,
such asfor instance a crank 40, the shank of which bears a pinion 41 meshing with a second pinion 42 keyed on shaft 39, the liftin frame of the hopper may be raised throug 1 the medium of cams 38.
In order to facilitate the maintenance of the hopper in both lifted and lowered positions, 1t is of great avail to provide at convenient points of the cams 38, notches 43,
.whichy maybe engaged: by said idlers 37.
Various equivalent devices may, of course, be used to obtainthe same-eifect,as, for instance, the lifting frames may be operated by means of a rack upon which `vvill act pinions driven by a crank. Y
` `T he elements ofthe lifting mechanism may.
beprotec'tedb'y ajcasingfll, constituting any oil tank for lubricating purposes. Q
In the :machine illustrated, al mechanism for reciprocatingl vthe grinding block is provided at bothends of the rollers; such disposition ispreferable owing to the 4'considerv able friction between the vrollerl and the block 5; Itisobvious that one of these mechaynisms may be rreplacedby a return-spring of appropriate strength. A Itis "obvio/usY that 'with the device according to the invention, the reciprocating movement of the grinding block need not be in timed relation with the rotar movement of the roller and` it `is prefera le that there should be no timed relation between these movements, as in thiscase the peri heral sur-V face of the roller will be more per ectly used for grinding and lessrapidly Worn.y
The device as described is characterized by its great lsimplicity and solidity kof construe tion, as alsov by the fact that it can be fitted on grinding lmills of various types. It per-l mits of easy regulation for any kind of material-to be treated'bymerely interchanging the pinions ofthe mechanism'for reciprocating the grinding block. f
