lle it'linown that l, PAUL OLSON, a citizen otthe Lmied States, iesii'ling at Stoughton,
in the. county of Dane and State. of \.'iscoI 1- sin, huw invented certain new and useful lmpi'inements in llolary Mixers lorConi-i'et e. ol' which the following is .zi ls'peeiiication, had to the accompanyingdrawings.
My invention relates to improvements in roti-iin' mixers l'oivconcrete, cement andthe like, and it consists of the novel features olf' -construcli-.n andl the combinationand arrangemei i: o l" parts hereinafter fully described 'llheobject ol" the invention is to improve` and simplify the construction and operation ol' iiiacliines-'ol' this ycharacter' and thereby 'render the saine more durable and eil'lieient and less expensive'.
The above and other objects-'0f the inven illustrated in the drawings, in which Figi ire`1 is a side elevation of my improved 'rotary mixer., 'its body or drum being shown in its tilted position in dottedlines Fig, v2 is a vertical longitudinal'section;` Fig.l 3 is an :end elevation; and Fig. 4 is a transverse sec-r tion.
The invention comprises'a cylindrical body or drum 1- preferably constructed of. Wood and having a'lining 2 of metal. The open ends of the body are reinforcedby bands-0r hoops 3 and are adapted fto be closed by heads o1"l doors 4, 5, .which latter. are hinged .at 6 to lthe-.bandsS and are adapted to be-sefl curedin .their closed' position by suitable fastening devices?. Formed in 'the centerl ofsach of the heads or doors'is an. opening 8 lhose. or pipe for supplying water orfothferA through Which may be passed-the'end of a liquid to the interior of the'druin. Themafterial to be mixed is introducedinto the latter through a filling opening Q .formed in the druniadjacent to-its centerv and closed by a door or cover 1() hinged at 1]"and .provided with a, fastener 12.
The 'druin 1 is mounted for rotation upon a vsupport or frame'comprising a suitable base 1 3 from which rise two sets of transversely extending upright standards or'supports 14, 1.5,"j16.. The. standards of each set are ar ranged in parallel relation and are spaced apaitas shown, one set being arranged beneath the inner end of the drum and the other set at a suitable distance from its outer end for a purpose'presently explained. up'peredge of each of the standardspH, 15,.
.1 6 is recessed to receive said drufm and -Jo'urnaled between the standards 14, 1 5 of Lwith annular grooves 1S. gaged by annular bands or'rnigs 19 arranged to enter the grooves. IS in said rollers;
Fortlie purpose of rotating -the d'ruin l provide' beneath it, in suitable Iii-n.i'iiigs, in the standards 16,1 aloi'igitudinnlly extending shaft 2] on which aresocm'ud, between 'the standards 1516, pinions 222 which mosh with ring gears 23 secured upon the drum fl `l='pon By -inounting tliedrum las .above dilongitudinally or endwise as ini-Ii'eated in v dotted lines in Fig. 1 for the purpivse'of discharging its-contents from its untel-Tend whic is closedfby the 'door or'head 5.V
tilting' of the drum is effected by. providing upon the Center of itshead 4 a projection or 'nularl lliange 26- Iand havingv a longitudinal bore or openin 27'v'vhic'h registers with the Watersnpply hose. or pipe.- The projection `or .boss 2 51is looselyl engaged'by-asleeve or collar 28 to.. which are connected the upper *arepivote'dto the inner ends of tra nsvei'selyV extending `1e`vers'30. Theselevers'are pivthe outer ends of said leversproject-from O posite .sides of"v the. machine' and-'may he;
moved downwardly-by hand when it is de-'- ,the like, which is to Abe mixed is introduced each set 'are anti-friction rollers` 1.7 `lfm-mrd Said rollers u re onvat suitable points upon theah'um l and 1 formed with radial ribs. or [langesllu adapted the projecting inner or rear endoiv {lushnl't v21 1s a drivlng pulley 24 which niavbe'connectefd to asuitable source of power.
ends of rods l29,- ,the'low'er ends of which latterscribed, it will be seen that it may 'lw-y tillcdboss 25 formeda't itsfouter endwithan anv,opening-8j in t efheadiflgso as toreceive a o ted` intermediate' their ends at' 31 ',upon the standard 16 at the'inner-endof'thedruxn and" into `the body or drum 1 through the inlet endy or head' of opening 9 and the door or cover 10 is then laced in osition. The hose or pipe which 1s to supp y the water or other liquid is then introduced throu h the opening 8 in either tedrum. When power is applied to the shaft y2 1 to rotate the same its I motion will be'imparted through the gearing 221", 23 to the drum which Will be rotate upon the rollersl 17; After the material has been thoroughly mixed the head or end at the outer end of the drum is opened and the drunris' then' tilted by de ressing the outer 'end'of either fone' of the evers 30. When -this is' done the links or rods 29 will lliftthe merend of the drum., the flange 20 on the band o r ring 19 adjacent the outer end of the 'drum' .serving as' a fulfrum for the latter.
Owing to the provision of'thestraight long;- iudinalnnxer ribs Within the drum it will e [seen that y'its'ccnte'nts 'will be readily disi detai "a filling openin intermedia elw rgcdf when the drum is tilted.
While I have shown and described the pre- -ferred embodiment ofv my invention I wish it understood that I do not limit myself to the precise showing set forth and thatvarious chan es in theform, proportion and minor of construction may be vresorted to without departin from .the spirit or sacrific- 4in any" of the a vantagies of the-invention. Iaving thus describe I claim is:
scopesy drum, a drive shaft in saidsupport, pinions upon said shaft in mesh with said gears, an apertured concentric projection upon ,the closure at the inner end of the drum, a loose 'sleeve upon said projection, oppositely. projecting levers pivotedon the support andv links connecting the inner ends of said levers to said sleeve, substantially as described;
2. In a rotary mixer, the combination of on, a mixing drum', a band uponthe drum. ysuitably distant from its outer end and progrooves in said rollers and means at the inner end o'f the drum for elevating the same.
3. Ina rotary mixer,. the combination of a support, lgrooved. anti-friction rollers thereon, a mixing drum, a band Iupon the drum suitably distant from its outer end and provided with anannular flange to engage the grooves in.l said rollers, a concentric projecand a `link connected to the lever and loosely yen'gagIe'd with said concentric projection.
asupport, a drum rotatably mounted thereon and adapted to tilt endwise, a-concentric projection at one end of the drum, a sleeve ooselymounted on said projection, apair of' transversely disposed levers pivoted intersupport and af pair of crossed links having theirupper ends lpivoted tosaid sleevaand their lower ends loosely' pivoted to the inner ends ofsaid levers.
In testimony whereof -I hereunto affix my signature in the presence of two witnesses.
