' Application filed May 25,1902, Serial No. 109,024.

.Yorlr, in the county of New Yorlrand State of No York, have invented-a certain new and useful Improvement in Mixing-Machines,

of which the following is 'a specification.

My invention relates to machines adapted for mixing concrete, mortar, and the like, and involving a rotary mixing-receptacle arranged upon a movable frame or support which can be operated for the purpose of tilt-' ing the rotary mixing-receptacle.

Ob ects ot my invention are to advantageously support the rotary mimn -receotacle and permit it to be readil T ti ted to ll 7 provide simple and eliicient meansfor con tinuously rotating the mixing-receptacle to provide simple and el'licient means for operating the frame or support which serves to up. hold and tilt the rotary mixing-receptacle;

to apply power from an engine or motor for tilting the rotary mixing-receptacle from its recein'ng or mixing position to a position for discharge and also for-tilting the mixing-receptacle from its discharging position back to its receiving or mixing position; to automatically disconnect such power at each end of the predetermined extent of such tiltingmovement and also to permit an attendant to readily disconnect the power for tilting at any point between said two extremes or limit IV of tilting movement whereby the tilt of the mixing-receptacle can be arrested at will; also, to simplii the operating mechanism shown and described in my application for Letters Patent of the United States filed April 15, 1902, and serially numbered 102,960.

in the accompanying drawings, Figure 1- is a side elevation of a mixing-machine embodying the principles of my invention, the, mix. ing-receptacle being in position for receiving a charge of materials. Fig. 2 is a like view showing the mixing-receptacle tilted into 0- sition for discharging a mixed-up batch. I ig 3 is atop plan view-with the miXing-receptacle removed. Fig. is an enlarged detail view, partly in section and partly in'elevation, the section being on line :0 as in Fig. 3. Fig. 5 is a section on line so rt in Fig. e. Fig. 6 is a section on line y 1 in Fig. 3. Fig. 7 is a section on line 2 z in Fi 3; Fig. 8 is a vertical trans-- verse section oi the mixing-machine. 9

and 2, respectively arranged at diagonally opposite corners thereof and respectively providing the receptacle with charging and discharge passages or openings. These hollow journals-0i the mixing-receptacle are upheld by antifriction-rolls 3 on the movable su port B.

' he movablesu pport B has a curved or segmental ortion provided with a segmental rack, Whic is engaged and operated by a driving-pinion, a preferred arrangement being to construct the movable support as a frame having its segmental portion formed by curved side bars 4, each having a curved raclcbar 5. W ith such I arrangement the rack-bars are engaged bypinions 6 on a transverse shaft 7, and in order to further guide the movable iction-rol ls 8 on a standard 9, which rises from the bed-frame 10. This movable support or frame B can be sustained by a bed havin any desired number of antii'riction bed-rel s positioned at suitable intervals along the arc of a circle and will have ,a

rotary reciprocative movement when opersupfport its se mental bars 4 can ated to tilt the axis about which the mixing- The sup orting frame axis transverse to the axis of rotation of'the mixingreceptacle, and as a matter of course when-it is thus operated its end portions which support the mixing-receptacle will tilt or tip, thereby varying the surge of the longitudinal axis about which "the mixing-receptacle revolves.

The rotar' counter-shaft G is shown con: y

nected with the rotary hurting-receptacle by an endless power-transmitting belt or chain 4 i), and to such end the mix ng-receptacle and thecounter-shait are respectively rovided with sprockets l i 12 such chain I the tilt of the counter-shaft.

g earns? or belt. The end portion of the countershaft, which is provided with the chainor belt sprocket 12, is supported by a sleeve or bearing 13, having a pivotal connection with the movable supporting frame B, as illustrated in Figs. 2, 4, and 5, in which the bearing-sleeve 13 has a couple of oppositelyarranged pivots or trunnions 14, supported to turn in a bracket formed by cheek-plates 15, bolted to a cross-bar 16 on the movable supporting-fran1e, Figs. 3 and 5.

'The counter-shaft C is operated by a driving-gear E and also has a sliding connection therewith, and to such end the gear E has an axial bore in which the counter-shaft is fitted to slide. The gear E and the counter-shaft C are connected by a spline 17, Fig. 4, on one of such members engaging in a groove in the other member, whereby rotation of the gear will drive the counter-shaft and at the same time the latter will be permitted to slide longitudinally in the gear. The gear E is also pivotally supported by trunnions, so as to permit it to rock or tilt in conformity with As shown in Figs. 3 and 4, the hub portion 18 of the gear E is secured in a bearing 19, which is support ed; upon the bed-frame by trunnions 20 and 21, Fig. 4. With this arrangement the tron-- nion 21 is conveniently formed by one end of a transverse shaft F, having a bevel-gear H, whichengages and operates the beveled E. When shaft F is operated, the countershaft 0 will be driven therefrom and the mixing-receptacle will be rotated byreason of its gear connection with such counter-shaft, and when the oscillatory frame B is moved. for the purpose of tilting the axis of rotation of the mixing-receptacle the shaft C will slide one Way or the other through the rotating ear E, and the latter will. rock or tilt in con-- i ormity with the tilting motion of the rotating and longitudiirally-moving counter-sh aft. This longitudinal shift on the part oi the countershaft E is illustrated by comparing Figs. 2 and 8. In Fig. 2 the rotary mixingreceptacle is tilted. for the purpose of discharging the mixed-up batch, and in 8 the mixing-receptacle is in. position for receiving and mixing. It will be seen, however, that in both positions the axis of the countenshaft is parallel with the axis about which the mixing-receptacle revolves.

As a means for operating the oscillatory supporting-frame B the rotary shaft 7, having pinions 6, which engage the racks on such frame, is also provided with a worm-wheel G, which is engaged by a worm 22, Fig. 7, on the rotary worm-shaft H, Fig. 7. The shaft H is mounted upon the bed-frame and is also provided at one end with a bevel-gear 23,

Fig. 3. The shaft H is operated from the main driving-shaft F by suitable clutch mechanism, such as clutch hub or sleeve 24, Fig. 3, feathered to slide along and rotate with position illustrated in Fig. 2 to the recei shaft F and having a couple of bevehgears 25, which. can. be alternately placed iii engagement with gear 23 for the purpose of nmving the support B in opposite directions. in this connection I indicates a clutch-lever piv- 7o oted upon the bed-frame and arranged for shifting the clutch device on shaft F. 'i lever i can also be automatically ope ed for the purpose of arresting the moveu t ofthe oscillatory support B at either of the two 5 extreme positions or the latter. To such cud the shifting clutch member I has an arm 26, and the tilting frame upon which the min receptacle is mounted is provided w' tappets or stops 2? 2'7, spaced with rcrerence So to their required terms of service, one being" provided for engaging arm 26 of the lei as to shift the latter, and thereby "r ically disconnect the power from when the mixing-receptacle been tilted to an extent to place it in a predetermincd position for uisrha ge, the other one of said stops or projections 27 being provided to engage said lever-arm and. shift the lever so as to antomatically disconnect the power ironi shaft H when the ini "-receptacle ample, been tilted back from the a...

(Shown in Fig. 3.)
