l Tol all wo'm r't may concern:

Bel it known@ that 1,-1onpanoGnMivrRie, a' citizenv orv che United! States, residing at South Pasadena, in the county of Los Angeles',- State of California, have invented1 new and useful improvements in' Concrete- Mi-Xergof which the following isV a specification'.

This invention relates to concretev mixers and the principal object is to provide a com crete mixer of the street paving? type with a plurality of conveyors to li'tt the various materials from the ground level to be delivered into elevatedA measuring hoppeis. llt is also an object to provide a concrete mixer with independent chutes'to convey the diii'erent ingredients' that com-pose the concrete, and' operate each individually or cooperatively as desired.

It is also ail-[object to*A provide means for measuring a certain amount of ingredients in an elevated position and under the control of a single operator to be delivered to a common delivery hopper. f

It is a further object to provide means'fo'r folding. a portion of the endless conveyers occupying a position next to the' ground' level', together with a movable measuring bon by means of which Sina-ll quantities can' be measured from the elevated hoppers as desired.

In the drawings accompanying this specification,` Figure l yis an elevationshowing the applicationof the invention to an ambulatory concretemixer. Fig. 2" is a side ele-V` vation of a' portion of' a movable concrete mixer, showing the invention ap lied thereto.v Fig; 3' is a front elevation o I 'the mixer,

showingI the endless conveyers and the-means for driving the same. Fig; 4' is a` section on the line 4 4 of'Fig: 2 viewed in the direction indicated by the arrows, the section be#y ing' through the elevated hoppers and the platform adjacent thereto and the driving shaft of the prime mover'. Fig. 5 is a perspective view of the elevated measuring hoppers with their dischargel gates into the maan chute or hopper, together with the auxiliary measuring box.- Fig;v 6'. is a detail y section on the line 6--6 of Fig. 5, viewed in i necessitating the presence of a large number of laborers at this' point to bring the proper materials for the mixture, together with the delay indelivering the material should one or the other of the ingredients be more remote from the mixer or a mistalrebe made by the materialE man and his handlers, and with these large movable skips greater danger is incurred of their falling with the heavy weight and injuring the workmen.

This invention overcomes the above diicultie's in that the materials are deposited in rows onthe ground level by the dump wagons and shoveled into the lower hoppers without the use of'wheel barrows and elevated by conveyers incapable of falling to injure the men seriously, and the control of the mixing operation can be performed by one man who is stationed on a platform adjacent the elevated measuring hoppers, who at a'll times has complete control over the conveyers and an unobstructed view ot all theI operations of the machine. 1 j,
