Application filed February 7, 1924. Serial no. 691,293.

To allwhom it may concern:

Be it known that T, GEBHARD JAnenn, a citizen of the United States, residing at Columbus, in the county of Franklin and 6 State of Ohio, have invented a certain new l a single opening for the feed and discharge of the component materials usually has such vessel mounted in a frame with a skid or more commonly upon a wheeled truck to facilitate its movement from job to job.

Such a mixer is usually provided with a loader bucket for feeding the materials to the mixing vessel pivoted to the frame of the machine and suitable power mechanism for raising it to mixing vessel-feeding position 29 and then lowering it to the ground for the reception of afresh supply. As it is important that the loader bucket shall lie as closely to the mixer as practicable and 'as it must be raised to a relatively high point to deliver the materials to the mixing vessel it is a desideratum thata long radius of swing of the bucket to mixer feeding position be avoided.

Several varieties of means have been proposed and illustrated in patents for accomplishing these results and the object of the present invention is to provide improved and simplified means to the same ends.

The present invention is embodied in th construction herein shown and described the features of novelty being finally claimed.

in the accompanying drawings- Fig. 1 is a view in side elevation illustrating a mixing vessel or drum and loader 4 equipped with my invention showing the loader on the ground with some operating parts omitted for the sake of clearness of illustration.

Fig. 2 is a similar view showing the loader raised to position to discharge its contents into the mixing drum.

' Fig. 3 is a View in elevation looking at the left hand side of Fig. 1 with the loader vessel removed.

Fig. 4; is a view like-Fig. 1 showing a modification.

In the views 5 designates the mlxmg was i sel which is mounted upon a center spindle in a swinging yoke 6 journaled in bearings in a suitable frame 7. Such a mixing drum is usually turned on its arms by means of of which are hingedat 9 to a link frame 10 that in turn is hinged at 11 to the main frame 7 or suitable ears 12 projecting therefrom. The frame 10 constitutes a pendent swinging link connecting the loader bucket The loader bucket is to the main frame. also equipped with a cable or cables 13 for raising and lowering it, said cables winding on a drum or drums 1t fixed on a shaft 15 journaled in the upper end of the main frame. The shaft 15 is driven by a sprocket chain 16 traveling around a sprocket wheel on the end of the shaft, said cable being driven by an engine (not shown) but well understood and as in common use.

The .main frame is provided with a suitable stop at 17 to limit the leftward oscillation of the link frame 10 and to afford a purchase for the weight of the bucket in its initial swing upward. This stop is'advantageously located at a point somewhat to'the left of the vertical line from the hinging point 11 because it permits the ground posi vtion of the loader bucket to be that much fitldStjED i nearer the main frame when it is deposited on the ground.

If it be desired that the loader bucket when lowered shall rest upon a plane 18 below the plane of the bottoms of the truck wheels a link frame 10 with longer side bars can be substituted for the corresponding parts shown in Figs. 1, 2 and 3 and as illustrated in Fig. 4 where the bucket is.

sions 8 abut against the upper portion of the link frame after which the bucket turns on the axis 11 to discharging position as indicated in Fig. 2.

The forms of the parts can be changed without departin 'from the gist of the in vention as claimed.

What I claim is:

-1. The combination with a mixing vessel and a frame for supporting the same, of a loader bucket for the mixing vessel, means for pivoting said bucket with reference to the rame consisting of a pendently hinged link, said link having a hinged connection at its free end with the loader bucket, and means for raising the bucket first on the lower axis andthen on the other to mixing vessel charging position.

2. The combination with a mixing vessel and a frame for supporting the same, of a loader bucket for the mixing vessel, means ivoting said bucket with reference to link to oscillate from one side of a vertical line from its hinging axis to the other, said link having a hinged connection at its free end with the loader bucket, and means for raising the bucket first on the lower axis and then on the other to mixing vessel charging position.

3. The combination with a mixing vessel and a frame for supporting the same, of a loader bucket for the mixing vessel, means for pivoting said bucket with reference to the rame consisting of a pendently hinged link, said link havmg a hinged connection at its free end with the loader bucket, and means for raising the bucket first on the lower axis and then on the other to mixing vessel charging position and a stop for limiting the swing of said linkvat its innermost position. v I

4. The combination with a mixing vessel and aframe for supporting the same, of a loader bucket for the mixing ,vessel, means for ivoting said bucket with reference to the ame consistin of a pendently hinged link, said link having a hinged connection at its free end with the loader bucket, means for raising the bucket first on the lower axis and then on the other to mixing vessel charging position, and a spring acting on said bucket tending to draw it from said charging position.
