2T0 azz iuhorn it rim/3] cancer-1m: v 'Be it known that I, VVILLIAM J J UDD,- a-citiy zen of the United States,residing at New York, .in the county of 'NeW York and State of New York, have invented a certain new and useful Improvement in Ma-chines for Mixing Concrete or the Like, of which, the following is'a specification. v i 4 v .The objects of my invention are to rapidly and'efl'ectively .mix together the ingredients for-forming'a batch ofconcrete, mortar, or

chargeof the mixed-up batch; to shorten the -.distance between the charging and discharge openings of the rotarymixing-receptacle and at thesame time increase the capacity of the mixing-rec'eptacleand adaptitto rapidly and effectively eject the batch when it is in position to discharge; to dispense with the use "of blades or agitators Within them ixingrreceptacle, and thereby avoid clogging and permit a free discharge of'the-batch; to so form the inner walls of the rotary mixingreceptacle thatits rotationwill cause a quick and effective discharge or ejection of thebatch; to provide i'neonnection with a rotary mixing drum or receptacle a support therefor which is particularly adapted for large machines; to support the rotary mixing drum or-receptacle in away whereby the support therefor canbe readily tilted and easily'stoppedat any time,

during its tilting movement; to balance the rotary mixing-drum and its tilting support,

Y whereby the latter can be ea'silytilted to any desired extent; to sustain the tilting support for. a rotary mixing drum or receptacle upon a bed or base in anovel and. improved way; to

provide a hopper which can oouple-withzand' directly discharge into arotary tilting mixing drum or receptacle when such drum or receptacle-is in receiving andmixing position and which can be uncoupled from such drum portions.

support when the latter-reaches the desired limit 'of its movement either way; to prevent the materials which are being mixed Within the revolving .mixing' drum crreceptacle fromsplashing out through its dischargeopening; to close the discharge openingof the rotary mixing drum or receptacle when such drum-orreceptacle is in mixingpositionand to automatically open thedischargeopening when the rotary drum or receptacle" is brought into position for discharge, and to provide certain detailsserving to increase the general efliciency of mixing machinesfor con? 'crete and the like. a

Referringto thefirs t six figures, A. in licatcs a cubiforin mixing-receptacle having charging and discharge openings 1' and 2, Fig. 5, respectively, at diagonally opposite corner to rotate about an'axis passing through its oppositely -arranged ,chargmg and discharge This mixing-receptacle is arranged is coupled with a'revolving mixing drum or'i openings and is supportedito' tilt or oscillate;

the receptacle.

about a horizontal axis transverse to its axis i being composed of segmental side portions 5) ofrotation and passing relatively between its charging and discharge openings, so; that While it is being rotated it can also be tilted about an axis tr isverse to its axis of rotation in order to position its axis of rotation horizontally, or substantially so, for the purpose of mixing its contents or to bring its axis of rotation'into an inclined position, and thereby allow its contents to be discharged through the discharge-opening, as may be desired. Practically, therefore, the mixing-receptacle rotates about a tilting axis which passes through its diagonally opposite charging and discharge openings and tilts abhut a horizontal axis-which is transverse'to its axis of rotation and relatively between its charging and discharge openings-that is to say, the axis about which ittiltsis in point of position between its charging and discharge openings, although such axis may either intersect or be above or below the'longitudinal axis about which the mixing-receptacle revolves. I

The cl arging and discharge openings of the mixing-receptacle are prolonged or extended through necks or hollowjournals B B, which project Erom diagonally corner portions of These necks or hollow journals bear upon antifriction-rolls C, which are in turn arranged upon a tilting support D, adapted to move in conformity with and for the purpose of effecting the ,desired tilt on the part of the axis about which the mixing-receptacle rotates. The tilting support I) is capable of'par'tial rotation in opposite directious about an axis transverse to-the axis about which the mixing-receptacle revolves and has a range of movement sufficient to permit it to vary the angle or the'axis of rotation of the'rnixing-receptacle accordingto requirements. While the mixing receptacle partakes of the motion of its movable support when the-latter is operated to vary the angle of the axis about which such receptacle rotates, the movement of the mixing-receptacle caused by the oscillation or partial rotation of.

the support -D may be conveniently and comprehensively defined as a tilting movement,

since the axis about which the mixing-receptacle rotates is tilted, and, moreover, opposite portions of the receptacle in either case tilt about an axis transverse to the axis about which the receptacle as a whole rotates, and likewise while the support 1) makes a partial rotation about an axis transverse to the axis of rotation of the mixing-receptacle the end l l l l l l portions of the-said support, which sustain the mixing-receptacle, necessarily have 'a 'tilting movement. v. The support D is sustainedbyandworks upon suitably-arranged 'ro" as antifriction-rolls 3,"and ture of a segmental frame or a frame having a. segmental bearing portion which bears on the antifriction-rolls and which is shown as bearings, such and is in the nalatter beingin turn supported upon the basefra'm'e E. \Vith such arrangement the, segmental sides 5 can be tied together by any suitable transverse connection -for example, by 'the end cross-bars 6 and 7 and by any further intermediate .transverseconnections which may be desired. Force of power suitably applied will cause the segmental sup-- port or support having a curved base portion to traverse its supporting-rolls and make a partial rotation in one or the other direction, as the case may be, and in so doing'tilt the mixing-receptacle, and thereby vary the angle of axis of revolution of the latter aboutan axis around which the tilting support operates. I The hollow journals B B provide suitablyprolonged charging and discharge passages or. openings and also project from the cubi form box to extent to permit them to properly engage the antifriction-rolls C. The rolls G are arranged to engage these journals at opposite sides thereof, so-as to prevent lateral displacement of the mixing-receptacle, To avoid displacement of the mixing-recep, tacle in a direction coincident Withits axis ofrevolution, the hollow journals are provided with annular offsets 6, in which tie antifric-' tion-rolls engage. hen the mixing-recep-- tacle is'in position to receive thematerials and to mix them together, its axis of rotation is preferably horizontal, or substantially so, and

when in such position it receives the mater rials from a hopper Gr, which issup ported by a frame-standard Gr,

The walls of the hopper are arranged to direct materials thrown therein-toward its discharge opening, which registers with the:

- charging opening of the mixing receptacle whenthe latter is 111 receiving position, as in Fig. 5. In .order to prevent escape of materials passing from the hopper to the mixingreceptacle, the discharge-opening for the hopper is essentially formed through a neck 8, arranged to telescope or couple with the hollow journal B of the mixing-receptaclewhen such receptacle is in position to receive from thehopper, as bestillustrated in Fig. 5; With such arrangement the hopper is movably supported whereby it can be moved away from the mixingreceptacle when it is desired to turn or tilt the latter into position for dis charging its contents. As a simple arrangement the hopper can be hinged .at its upper portion upon the standard, as at 9, whereby its lower discharge end can swing toward and 'away' from the niiXlngreceptacle. here {the hopper is thus arranged as a pendent device, its short discharge neck or spout 8 can' project laterally from the side 10 of the hopper, which is opposite the mixing-receptaele, which said side may normally stand on or about a vertical plane, while the remaining III charge-opening of the mixing-receptacle is is hinge-supported upon the movable support 20 i When the mixing-receptacle is brongh't' into door will-open the discharge-aperture.

As shown, the neck orshort spout 8 of the hopper .is adapted to enter the hollow journal B, of the mixing-receptacle. ,This' ar- Y rangeiiient avoids leakage when the hopper;'

is discharging into the mixing-receptacle, and at the same timeitpernnts .the n1ixing-recep tacle to be continuously rotated. The disnormally closed by a valve or door H, which for the mixing-receptacle and arranged so that 'positionfor discharging its'contents the said As preferred arrangement-and matter of furtheri'mprovement the door H is a gravity door and made of such weight that it will normally hang as in Fig. 3 whenthe mixing-receptacle is in position to discharge] \Vith such arrangement the hinged pendent door will a'u-' journal B of the mixing-receptacle when the latter is brought to the position shown in F 1g, 5, and when the mixingreceptaclc lsbrought low discharge-journal will leave the pendent door, as illustrated; and thereby open the dischargeaperture. The support shown for said door compri. movable support D and arranged to stradgille the journal 15, and a bent' arm 19-, secured to the door and hinged to the yoke, so as to permit the door to readily accommodate itself nal B" under difierent conditions. By such arrangement-a larger quantity. of material can be mixed and splashing out .througlrthe discharge-openingwill be avoided. Also when or tilted to bringit into posit-ion for discharge its contents will not be thrown out from the dischergo-opening to aiiiilnlesiialJle extent, g since in such case this gravity door or'va'lve will serve as a deflector against which the materials ultimately discharged from the mixing-receptacle will impinge.

from its charging to its discharging position,

whereby the tilting movement of the rotary mixing-receptacle willbe automatically arrested when suchreceptacle has reached either of its two extreme positions. Broadlyconsidered, the above-mentioned de'vicesfor tilting or tipping the mixing-receptacle and-for automatically arresting its .jtilting or. tippingmotion can be employed in connection with a rotary tilting or tipping mix-ingreceptacleor drum of any known or desired form, and like wise the hopper herei nbefore described ican also be employed inconnection with other forms oi urotary tiltlng. nnxingreceptacles 'h'avi-ng opposltely-arranged charging and discharge openings.

In .co'nnection'withthe movable hopper I provide means whereby it canbereadilwinoved aava-y from the mixing-receptacle whenever it is'desired to tilt or ti p the latter from its receiving to-its discharging position, and I, also ceiving position. The means or devices thus employed ior operating the' hopper can also be employed in connection with other desired 1 orsuitable forms of mi'xirig-receptacles. More i specifically,referring to devlces herelnillustrated and embodying the principles of my invention, the rotary mixing-receptacle1spro vided with a sprocket I for'an endlizss drifiing chain or cable K. This driving chain or cable passes about and is operated by a driving-sprocket- L, Fig. 1,- on the base-frame or any suitably-supported standard-'13 and is conx-eniently guided by pulleys 1e 15 on the} movable support for the rotary n'iixing-recelr' 'tacle. By'such arrangement the driving-gear,

COIDPFISlDg an endlcss,cha1n'-passing about;

pulleys on the tilting 'su ppo' rt and rotary drum or mixing-receptacle, will maln'taina un form relationship, to the drum or receptacle and tilting support, since the pulleys on the support will be maintained at a fixed distance fronl the pulley on the rotary llllXlilg'dlUiil or receptacle. The dr1v1ng-sprocket L- re- I' also provide mechanism 'tacle I provide mechanism whereby the power provide means whereby the hopper is auto- 1 inaticallybrought into cooperative relationi ship with the mixing-receptacle.when the latv ter is brought from its discharging to its 're- I-oo volves and the rotarymixing-receptacle tilts Y about a common axis, and hence by properly positioning the guide-pulleys Li and 15 upon the movable support for the rotary mixingreceptacle the tilt or rotary adjustment of such support about'sanl 3X18 for'the purpose of tilting or tlpplng the rotary mixing-receptaclc can be eifected without causing the driving-chain to either slacken or become unduly taut. Whenthe mixing-receptacle is 111 position to receive materials from the gravit -hopper, the latter will hang in'position to couple or. connect with the mixing-receptacle and to dischargetherein, as best illustrated 1,. 1n 1 lgs. 2 and 5, When, however, the movable support D for the mixingsreceptacle is operated to tilt or tip the latter. and bring into position for discharging its contents, as in 3, the hopper can be caused to move or swing in a direction away frolnthe mixingreceptacle, and thereby uncouple therefrom, so as to permit the movable support and the' ing-receptacle when it is desired to cause the the n latter to tilt or tip ina direction to discharge its contents- The lever M can be fulerumed upon an u 'iright portion 16 oi the base, as in Fig. i, and have one of its ends connected with a bar or arm 17, which is secured to one side of the hopper. 'The connection shown between the lever M and the bar or arm [7 on the hopper consi .s of rod 18. attached to the lever and extending upwardly: through an opening in the bar 17. The rod 18 has thereby a sliding connection with the bar 17, the extent o'f'its movement independently of the bar being limited} "steps 19 and 20 on the rod. \Vhen, therc'fr the handle end of the lever M is depressed. its opposite end will rise, and therebyniove rod 18 i'ipuurrdly, and as-the result of such action stop 20 will be forced against the lowerincline'd portion of bar 17, and thereby cause the hopper to which bar 17 is secured to swing in a direction away from he mixing-receptacle and disconnect or uncouide its dischargo-passage from the charging-opening of the mixing receptacle.

This action also frees the bar 17 from a catch 21, which After the hopper has been thus swung away from the mixirig-receptacle, as

latter is in receiving position, at whicblijunc ture the lip will clear the upright portionllfl? of the bar H, and thereby allow the hopper to swing into position to couple onconncct with the mixing-receptacle, as shown in full lines in Fig.5. l/Vhen, therefore, theinixing-re ceptacle isin receiving position, it is locked or held against tilt, and when it is desired to tilt such vrecepta'cle,.so as to position it for discharge, it is unlocked, and the hopper is uncoupled or disconnected from its receiving opening; On the other hand, when the mixing-receptacle is brought into-receiving position the hopper automatically connects or couples with its receiving-opening. When the mixing-receptacle is in position to discharge, the end thrust incident to such position is taken by an antifriction-ro'll N, Fig. 5, carried by the movable support D and arranged to rotate about an axis at right angles to the axis aboutwhich themixing-receptacle rotates, the mixing-receptacle being in such case provided with an annular race or bearing Any other ever, be provided for thus sustaining this end thrust of the mixing-receptacle when thelatter is in position to discharge its contents. The hand-lever can also be employed for operating clutches, whereby the driving p-..wer can be connected with the movable suport- D, so to operate the latter. As best lustrated in Figs. 1 and 6, 0 indicates a :ansversely arranged counter-shaft having a sprocket or. pulley 23, which is connected by a link or chain belt 24: or other suitable p0wer-' transmitting conuection with a pulley .or sprocket 25 on a driving-shaft Z6, whichlatter carries the driving sprocket or wheel L,

hereinbet'ore described. The-- axis of this driving-shaft L is in alinenient with the axis, about which the movable support D makes its partial rotations 'and about which the mixingreccptacle tilts or tips. The counter-shaft ()is provided with a couple of loose-winding drums 37 and 28, Fig. 6. the former for a chain or cable 29, which connects with opposite end portions of the movable support '1) and the latter for a chain or cable 30, which likewise connects with opposite ends of said inovable support. These chains or cable 29 and are arranged to relatively wind in opposite diwhereby while the counter-shaft- O rotates in one direction onlv the movable support l) will be moved in one or the other direction, ac-

The 'wiiiding drum 27 is provided with a clutch-section 31, and the Winding-drum 2B is provided w'itlna clutch-section -5 32,-and hetween these two clutch' sectio'ns is a double-clutch section 33, which is keyed or feathered upon the counter-shaft '0, so, as'to rotate therewith andialso slide thereon. hen, '.therefore, the double clutch section 33 is IQ shifted-so as to "engage the clutcl'i-sectio'n on one of the winding-drums, the cable passing aboutsuch drumwill be operated ina-way to positively-moye'the support D in a'direction to tilt the mixing-receptacle from its receiv- I5 ing to its discharging position, while the other cable will s'i'mply'wvind upon and unwind from the drum about which it passes.

In Fig. 6 the movablesupport D-for the mixing-receptacle is understood to beih position to. place the charging-opening of the mixing-receptacle in register with the dis- Under the arrangement shown in said figureth'e movement of support D in a direction to bringthe mixing-receptacle into position 'for dischargr ing its'contents can be effected by bringing clutch members 33 into clutch 'with the clutch member 31-, whereby the winding-drum 2? will rotate with shaft O in a'direction t'owind up the cable portion shown at the right of said drum and payout the cable portion shown at 4Q the left ofthe drum, while, on the otherhand,

the drum 28 bein'gloose-on the shaft will be" revolved by the action of cable 30 in a di rection the reverse of the rotation of drum 2?, the portion or cable '30- at the right of drunr28 the left or such drumpays out. In bringing themixing-receptacle from its discharging to its charging position the converse of the fore. goil'ig-described' operation takes place. The .3 5 clutch 33can beshifted by a vibrato-1w clutchi lever 34; which latter can in turn be operated from lever M througll the medium of a-bcllj crank 35, Fig. 1, pivoted on the base-frame, f a link 36 connecting lever M with one arm of the 'bell crank and a connecting-ro 37 1 connecting the other ar'mot' the bell-crank f with the clutclr-lever34. By such arrangej inent 1 provide a clutch device and a cl'ntchshifter, wherebythe power emplovedto continuonsh revolve the mixing-receptaclecan at; will be applied .t'or moving the support for the mixing-receptacle in eitherdirection.

In order to guide the chains or cables 29 and 30, I pass them about nrlleys 38 and 39,

Then, therefore, clutch member 33 is placed] in clutch wit-h clutch member-31,- the cables 291ml 3!). will travel to the left until stop 41 on one of such cables engages stop 42 on-the rod 1, at

which juncture the'action of stop 41 against the-stop on the rod will cause the latter to shift in a directionto operate the clutch-lever 34, and thereby disconnect clutch member 33 from clutch. member 31. In this Ywgv; the cable 29 will be disconnected from the driving power when the rotary mixing-reoep- 9 tacle reaches a position for discharging its contents. ()n the other hand, when clutch member 33 is placed in clutch. witlrclutch member-32 the movable supportfor the mixingreceptacle will be operated in a direction to bring the latter into receiving position, and

'ata proper moment such movement of the movable support forthe rotar vmixing -reccptacle .will be ql'ieckedby reasonof stop 1 moving with cable 30. from left to right ind acting against stop 43 on rod P, so as to shift the latter ina direction to cause clutch inc-mher to separate from clutch member 31 By such arrangementthe movable support for m the mining-receptacle is automatically discon- 5 nected from thc'driving powcriivhen itreaehgs the two extiemes of its desired'e'xtent of movement, which said two extremes of movement determine the receivinga-ml discharging po-r sitions ot'ltherotary mixing-receptacle. no

In order to swinglthe hopper away from the mixingreceptacle and simultaneously there with to shift clutch member 33 into clutch with thecluteh member onwinding-drum 27, it will only be necessary for the attendant to depress the handle .end of level- M, which lat ter will thereby be swung in a direction to cause stop 20, Fig. 2, to act against the lower inclined end portion ofthe, armor bar I? on the swinging .hopper.and also to cause the riections with lever M, to throw clntch'member into clutch with the clutch member 31. \Vhen the mixing-rece 'itacle is in position to dischargciand itis'dcsircd to cause it to move a into position to reeeivefrom the hopper, the

attachment will raise the handle end of lever M, whereby the latter through the Incduuu of its connections with the clutch-lever 34 w1ll cause such clutch-lever to operate in a direction to throw clutch member 33 into clutch with clutch member 32 on the Windingdrum tain the hopper away from the mixing-receptacleuntil such projection 21 passes below the lower horizontal portion 17 of the bar or arm I), at which juncture the arm and hopper will' swing back into the position shown in Fig. 5.- F1gs. 7 and 8 illustrate a tilting-frame D, pivoted or trunnioned upon side standards of the bed or base frame and employed in place "of ,the segmental tilting frame D, hereinbefore described. Where the pivoted frame I) is thus employed in place of the segmental tllting frameD, all of the othermatters illustrated by the first six figures can be applied,

fas will be understood without further illustration, and description, and hence various matters shown in the first six figures are i omitted from Figs. 7 and 8 simply for convenience in illustrating the use of a pivoted Itis also understood thatthe hopper and the mechanism or devices for connecting and disconnecting the driving power with and from the tilting support can be employed in connection with any other desired form or construction of tilting support and with any suitable form or construction of rotary tilting mixing drum or receptacle.

Vith further reference to the rotary tilting cubif'orm mixing-receptacle illustrated I am enabledby such constructionand arrange- 'ment to provide a batch-mixer of large capacity without undesirably prolonging the machine and to quickly and effectively discharge the batch of material therefrom. I am also enabled by such construction and arrangement to dispense with the use of mixing-blades arranged within the mixing-receptacle and to rapidly and effectively mix the materials without. clogging and to discharge the same more freely and perfectly than where such mixing-blades are used. This rotary tilting mixing-receptacle may be of a cube or E practically of a cube shape, or its shape may be somewhat modified without departing from the-general principles of a mixing-receptacle in the precise forni of a cubeas, for example, the mixing-receptacle could be somewhat prolonged in the direction of its axis at the expense of making a longer reccptacle, or the angles of its sides could bcsomcwhat varied or its sides could be multiplied.

It is understood, therefore, that I desire to broadly cover a cubiform or polyhedric rotary tilting receptacle having charging and discharge openings, respectively, at opposite corners and respectively adapted and arranged discharging the batch when mixed, but that I regard a cubiform receptacle substantially as shown and operated as a matter of further and special improy ement.

- I am aware that rotary cubiform or polyhedric concrete mixing-receptacles have heretofore been proposed, as evidenced by Letters Patent of the United States No. 306,522 to E. L.'Ransome, dated October 14, 1884, No.366,591 to J. Lundi'e, dated July 12, 1887, and-No. 467,302 to Pitc-hford and Cooper, dated January 19, 1892. ever, do not embody the feature of arotary cubiform or polyliedric mixing-receptacle arranged to revolve about a'tilting axis and having openings at diagonally opposite corners or yertices, respectively, for receiving a batch of materials and for discharging the mixed-unbatch, In the machines shown in said patentsv the batch is dumped by providing the receptacle with a side door, which is i opened .to permit the discharge when the rotary receptacle is brought to a standstill. In

rotary receptacle revolves. about a vtilting axis extending throughopposite corners or vertices formed by intersecting planes, whereby the charge or batch will dump or discharge when the axis of rotation is tilted and while accordance with my invention, however, the

mentinsures rapid and thorough mixing of the materials without the assistance of mixing-blades, which induce clogging of the materialsand retard the discharge, it being also observed that the plane surfaces arranged to form angles within the rotary tilting receptacle will keep up the agitation of the materials to the point where the batch enters the discharge-opening. The rotary mixers of said patents do not. therefore, attain the improved results developcd and attained by my invention.

of a quick and complete discharge of the mixed-up batch of concrete ormortar when the cubiform mixing box or receptacle is turned or tilted about a transverse horizontal axis, so as to incline its axis of rotation,which passes through diagonally opposite corners or vcrtices, as in Fig. 3. in which such mixing- .receptacle is shown in position for discharge, it will be observed that the lowest portion of the receptacle, which immediately extends back from the opening through which thegdischarge-takes place, need not at any time in the rotation of the cubiform receptacle slope downwardly toward said opening and that it will not so incline when the axis of rotation has the degree of inclination illustrated by Fig. and hence that as an inclination. of said lowest or under side portion or the receptacle downwardly toward the discharge-opening is not relied upon as a means for allowing the batch to slide out the receptacle need not be for admitting a batch. of m'aterialsand for These patents, hoW- the receptacle is rotating.- This arrange- 'ith further reference to the securenrent tilted to depress its discharge-opening to a greater extent than shown in Fig. 3, and in this way the receptacle need not be tilted to an extent'to bring the discharge-opening inconveniently under the receptacle. hen thereceptacle is thus in position to discharge, the material which is ejected through the dis-" charge-opening does not slide down and out along an inclined bottom way or gutter portion formed by a portion of the box, but is elevated within the receptacle and thendidiagonally opposite corners through whichrected to the discharge-opening, whereby it iseflectively freed frorntheinner sides of the receptacle. The principle of this discharge involves as a peculiar action the revolution of all of the corner portions of the cubiforrn box or receptacle, with the exception of the two 3 the axisof rotation passes, about said axis in inclined planes transverse to the axis of rotation and inclining upw'ardlyand forwardly,

top side of the receptacle and that its action in approaching such position tends to-divert It is not deemed;-

I receptacle and at the same time rapidly and receptacle.

andin this. way material in a lower corner portion is carried upwardly and forwardly toward the end of the machine at which the discharge is eflected. For example, in Fig. 3 the box is shown with its lowest corner portion in. .position for containing a quantity'of' material. If now the box is revolved, this corner portion will swing upwardly and for war'dly, as to the right in said figure, until it is in positionover the discharge-opening, and

thence it will swing downwardly and-back, as to the left, until it again reachesitsposition shown in Fig.3, and during such operation the remaining corners, with the exception of the two corners through which the axis of rotation passes, will have similar movements. It will also be observed that when, for example, the corner referred tois at the highest point attained during its revolution the side of the box shown in Fig, 3 will be shifted to a horizontal plane and momentarily form the the' material forwardly. necessary to thus follow the movements of all of the remaining sides of the box, it being understood that by their peculiar shifting to different angles when the axis of rotation is inclined, as in Fig. 3, the material is violently 'gitated, so as to free it from the walls of the effectively diverted and directed to the discharge-openings by reason of the shift in position of the inner walls of the mixing box or What I claim as my invention is 1.
