CHUTE-cimenteries MEANS.

Application led December 23, 1919. Serial No. 346,907.

To all whomt may conce/m; Y

Be it known that I, JOHN DANIEL, a citizen of the Unitedv States, lresiding at Milwaukee, inthe county .of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Chute- Operating Means, of which the following is a specification.

Certain engineering undertakings of 5the present day are attended `with remarkable and unusual requirements in concrete mixing. As an instance, the rapid laying of concrete roads has progressed to thepoint where as much as seventy linear feet of six.- teen-foot pavement have been put down per hour, and indeed a maximum of one hundred twenty six feet has been reached on certain work.

Obviously, operations like the foregoing necessitate the mixing of concrete in huge batches as large for instance as fifty live cubic feet, and therapid discharging of said batches from the mixing plant.

lViththe foregoing in view, the present invention comprises improved means whereby the discharging device of extremelylar'ge concrete mixers may be operated by power, and operated with speed as well. Y f

In the carrying out ofthe invention, I contemplate broadly certain lprovisions whereby themotion transmitted` to the mixing drum of the mixer may be employed, for imparting movement tothe discharge chute ofthe mixi'ngeniachine, whereby to throw vthe said lchiite 4into a position for discharging action andto position the same inoperative to perform its discharge function. i

rIhis invention involves improvements in the type of concrete mixing ,machine -illustrated by Koe'hringv Patents Nos'. 899,414 of September 22, 190,8, and ,1,126,487 of yIanuary 26, 1915, wherein the discharge chiite employed operatesasa mixing .element of the machine, owing to its function of. intercepting andjreturning toward the receivingendof the drum the concrete aggregates in recess of mixingor agitation.

, n machines of this type a very considerable load is constantly received upon-"the discharge chute as it lassistsin mixing,- and therefore the power means used according to this invention is especially advantageous when employed in connection Ywith discharging devices of this kind', though its utility,

of course, is not limited to anyparticular type'of 'discharging means for-'mixers In matter of fact, Athe means ofthe invention might be used advantageously for operating any associated moving part of the mixer where `the .manual operation is unusually burdensome. n

In the accompanying drawings which are to be studiedin connection with the following specic description of the improvements hereof;

`Figure l is a front elevation showing more particularly the mixing drum of a concrete mixer, equipped withy the means comprising the invention, in a preferred form.

Figure 2 is a vertical sectional view of the same. A

Figure 3 is a view and side elevation of the trip member. b igure 4 is an edge view ofthe trip mem- Figure 5 is a view showing a modified form of the invention lwherein an inclined cam means is employed as the actuating element for the trip.

`Figure 6 is a detail view showing more clearlythe cam device of Figure 5.

yFigure 7 isa side view of the trip used in theV construction of Figure 5.

yTo those versed in the. art the operation of the kcustomary rotating Vdrum A `of concrete mixing means at present commonly lused is obvious, the aggregates being received in the drumy and subjected to agitation by devices of the latter in the well known manner. The discharge chute for the'drumv or mixing machine A is designated. B and is pivotaly mounted at l upon a' stationary guard or splash plate so asv to incline inwardly into the drum to act as a mixing element, in which position it is inoperative for discharge purposes. The inwardly inclined position is illustrated dotted lines, whilst iniull lines the chute B is shown in its discharging position. The chute B may be operated manually by means of a lever 2 extending `from the shaft 3 supported on the frame work 10 which shaft 3 is connected by an arm l and link 5 with the chute B. GbviOUsIy, the rocking of the arm 4, outwards will shift the chute B into the dotted line position of `Figure 2, fr "om its .full line position. The manual lever 2 will not ordinarilybe used forthe operation of the chute B, though 'of utility vin emergencies and for the restoration of the chute to its normal position inactive for discharging purposes. i

The power actuating means for the chute is comprised of trips 6 which are spiined upon the shaft 3 and are shiftable in opposite directions by means of a hand rod 7 connected with the upper endsof spaced bars 8, one of whichis located at each side of the chute B and suitably pivoted at 9 on the frame work 10 of the machine, the latT ter carrying the part to which the chute Y B is pivoted. The trips 6 compriseffmem bers adapted to slide onV the shaft 3 under the iniiuence of actuation of the/parts 7 and 8, whereby either one of said trips may be brought into the path of actuating` means on the drum A, said means according to one construction comprising rollers 11 suitably journaled upon brackets 12 which are 6EL and thereby cause actuation ofthe shaft 3 so as to throw the chute B from an inop- `erative position for discharging, into its dis charging position. A movement of the trips in an opposite direction will carry the other trips into the path of movement of the rollers 11 thus causing a shifting or movement of the chute Bfrom its discharging position into non-discharging Under the conditions the load of operation of the chute B may by the aforesaid mechanism be placed upon the drum itself, and the latter being power driven no difficulty will be experienced in securing the desired operation of said chute. This is true irrespective of the quantity of materials of the aggregate being mixed falling upon the chute B, if the latter is of the type constituting a mix ing element. v

, In Figures 5, 6 and 7, there is shown a somewhat circular cam actuating element 14 aiiixed to the ring 13V of the drum A and adapted to engage a trip 15 in the form of an arm mounted on the shaft 3. A hand lever 16 on a shaft 17 is adapted to operate the yoke 18 which engages the grooved head 15a of the trip 15, wherebyY to shift the trip l5' into arposition wherein its roller 15b will enga-ge the cam element 14. The latter during theturning of the drum A will rock the arm 15 and cause rockingof the shaft 3 suiiiciently to move the chute connected therewith,l to a discharging position. The turning of the chute to a non-discharging position.

position may be'accomplished by'hand, or if desired by a movement of the arm 15 into cooperation with a cam element like that designated 14, but which is disposed' reverse thereto. n Y i Obviously, various modifications in the `detail` features including the actuating elements on the drum, and the trip means connected withthe shaftloy which the discharging chute or a like associated device is operated, may be employed so longV as the generalA principle Y of transmitting movement rom one part toanother is utilized.
