Be it knownthat l, JAMES B.' HINOHMAN, a citizen of the United-,States of America, residing at Denver, in the city and county of Denver and Stateof Colorado, have invented certainnew andy useful Improvements in Mixing-Machines, of which the following is a speciiication, reference being had therein to the accompanying drawings.
4This invention relates to new and useful improvements iny mixing-machines and belongs to that parti'cnlantype-of construction known as drum-mixers.
The machine involved is especially d esigned for mixing material to be employed in building construction in, either its dry or liquidstate, andinsuch application means are provided vwhereby the -material vmay be mixed continuously or in batch. g 'It is a primary object of my 'invention to provide meanst'or effecting a more prefect I amalgamation'ofthe granular particles; and
of the drum without; being-j4 allowed egre sstowardthe attainment of thsend the inven-- -tion specifically resides inv the provision `and arrangement lofa series of bafiimg'and carrying'wingsl mounted within the rotary-drum.'
In connectionwith the wings I employ a,l
delivery-spout of novel construction, which comprises two members designed to be held together inV overlapping or registering `position to feed the amalgamated material from vthe drum after the completion of the mixing operation andy adapted during the progress ofV themixing. operation tobe disengaged from one another, lso as to leave an-.open space in,
the i' spout through which the lmaterial con'- -tinuously' gravitates in the rotary movement therefrom. v y
The Vdetailed construction 'will 1 appear in the course of the following descriptionhin which reference-is had tothe accompanying' drawings, forming, a part of the specification,

showing in detail the construction of the ,v
' spout and the'supportingfframe therefor.
Referring specifically to the accompanying drawings, it will be observed thatI employ a rectangular frame 1, mounted on axles. 2,
upon the ends of which wheels 3 are journaled. The frame 1 constitutes a support for the superstructure which is moved upon the wheels 3, although I may eliminate these wheels land employvother supporting means well known in the art, such as skids, tc.
The drum '4 is revolubly mounted upon the frame 1 and is supported upon rollers ,5 formed on their outer sides with peripheral,
retaining-flanges 6, which overla for a short distance the sides of the drum. he rollers; 5'
are ,arranged in axially-alined pairs onl opp vsite sides of the frame 1, one pair ofsaid rollyers being `revolubly journaled upon the rear axle 2, and the other pair being 'journaled upon an axle 7, located in 'the same plane asthe axles 2 and'centrally disposed therebetween., ,The drum 4is prov/ided a short tance from each of its sides with peripheral flanges 8, which bear against the inner sides of the rollers 5 and coact with the flanges 6 upon the said rollers in positively maintaining the drum inV its position.-
The rollers 5 constitute a positive-support and cylindrical bearings for the drum in, its rotary movement and in this function coperate with the driving mechanism, which ymay be of any desired form, but which as shown embodies la sprocket-and-chain, gearing drivenfrom'a source of power-supply. The frame 1 carries adjacent to its front end a transverse shaft 9, upon which is mounted a drivefpulley 10 and a small sprocket-Wheel. `11. The-drum 4 carries on its periphery a 14", whichl are formed with inclined top edges 14C, as clearly shown in Figs. 3 and 4. Centrally located in the spaces between the ,wings 14 and secured to the imier circumference of the drum 4 are a corresponding series of Wings 15, which .shall be hereinafter des- IOO l'lO
' movement thereof.
ignated as baffling-wings. The wings 15 are of V shape, and the inclined sides 15L thereof extend rearwardly, so as to direct the material against the converging side walls 14b of the next adjacent carrying-wing.
The drum 4 is formed in its ends with openings 16, as usual, the circumference of said openings being concentric with'the periphery of the drum. Mounted upon one side of the frame 1 is a vertically-extending bracket 17, which supports an inclined feed-chute 18,
through which the material has ingress to the drum. I
The delivery-spout is shown in detail in Fig. 5 and is supported upon a frame of novel construction, which comprises an arch-shaped rear frame 19, secured to the side bar 1 adjacent to the feed-chute 18 and straddling the same, spaced supporting-posts 20, mounted upon the opposite side bar of the frame/1, and inclined top bars 21, secured at their one end to the post 2O and at their other ends to depending brackets 22, carried at the top of the frame 19.
Thel top bars 21 extend for a portion of their length in the same plane, their forward ends being bent aroundthe spout, as shown at 25, thus bracing the spout at.its outer or deliveryvend. kEach top bar has its rear portion 23 extending horizontally or at an angle to the main inclined portion, and said rear portions are suitably secured to brackets 22 vand carry a transverse bar 26, having a forwardly-inclined surface.
The delivery-spout is of substantially U shape in cross-section and comprises a sta- .tionary member 27, rigidly secured to the in- ,y
eline front portion of the top bars 21, and a movable-member 28, formed with hanged or channel-edges 29, which restupon the bars 21 and vserve as guides for the section 28 inthe The section 28 carries upon its underneath surface a handle 30, as shown in dotted lines in Fig. 2,whi'ch terminates in afhooked-end 31, designed to ride over and lockingly engage 'the `bar 26. The section 27 isv further'braced by connection with a supporting-bracket 32, secured'to one ofthe side bars of the frame 1, as shown in Fig. 2.
Upon referenceto Fig. 5 it will be observed that the sections 27 and 28 are shown innenregistering position, and the latter section is maintained in 'this position by the engagement of the hook 31, carried thereby, with the-bar 26; Arfopen space 33 is thereby left between the sections, through which the granulated material gravitates in the-rotating action of the drum.
lIn operation the sections 27 and 28 ofthe delivery-spout are vin the position shownin Fig; 5, the granular material .to be amalgalmated isfed yinto the drum 4 through the chute 18, which projectspinto the opening 16 in the'side Wall thereof,.and the drum is 'direct itP against the converging walls 14b of the next adjacentI carrying-wing 14, where it will of its own force gravitate toward the central portion 14 of said wings and be carried upwardly thereby until it drops in the inanner described and mingles with the bulk of the material in the drum. When the mixture has become thoroughly combined and it is desired to deliver the same from the drum 4, the section 28 is tilted so as yto disengage the hook 31 from the bar 26, at which time the section will gravitatedown the top bars 21 ofthe supporting-frame until it abuts and laps one-halfthe section 27. In this position, which is shown in dottedlines in Fig. 2, the sections 27 and 28 cooperate to form a continuous delivery-spout having.- an uninterrupted passage throughout its entire length.
.When the sections are thus joined or brought together, the drum 4- :in its rotating :Inove- Athat the carrying-wings 14 and the bafllingwings 15 eoact with one another to'thoroughly amalgamate the differentgranular matcrialsin the drum 4 in theo en position ofthe delivery-spout, and it l ybe further observed that in the.closed position of said spout the lcarrying-wings 14 act. as conveyers to feed thematerial into saidspout, down which it passes by gravity from the drum 4.
I have herein shown` and'desoribed a racvtical embodiment tif-supporting ftruc or frame for :the 'd1-urnas well as afdriving means forsaiddrum, but' donot wishto beiunderstood as claiming this ,construction,.fmy 'invention residing 'in "the construction of the drum and f-in lthe delivery-spout and support.
Other equivalent drivingmeans' than ,that -shownmay be employed,V and the drumy need not necessarily ybe' mounted -on a traveling truck.
Having thus describedmyinvention, what Iclaim as new, and desire tosecureby Let- :ters Patent, is*- IOO IlO
port for the drum, of standards mounted on said support, at one side of the drum, and a :frame mounted on lsaid support at the o posite side of the drum, spout-su porting ars connected at their ends to said ame and eX- tending into the d/rum on a horizontal hue and outwardly `vthereof at an incline to the horizontal, a spout formed of two sections, one of- Which 1s stationary on the inclined `1o portion of said bars andlwhich is secured tol bar,` tohold the slidable section separated from the stationary section.
