CONRAD F. GOERINGER, or WILKE-BARR'L, PENNSYLVANIA.

CONCRETE-MIXER.

To all whom it may concern:

Be it known that LCONRAD F. GoEnIN- GER, a citizen of the United States, residing at Wilkes-Barre, in the county of Luzerne, State of Pennsylvania, have invented a new and useful Concrete-Mixer, of which the following is a specification.

Concrete mixers are ordinarily loaded by transferring the aggregates to the bucket of the mixer by means of wheel-barrows, and in order to keep one size of mixer in continuous operation, requires the services of nine men and six wheel-barrows hauling stone, three men and two wheel-barrows hauling sand and oneman to place cement in the bucket.

In accordance with my present invention, I eliminate the necessity of employingthe wheel-barrows and the four men to handle them and also two or three of the menwho shovel the material, thereby reducing to a minimum the confusion arising from a number-of men and also reducing the operating cost from twelve to fifteen dollars per day, depending upon the price of labor at the locality at which the work is being done.

To the above end, my invention consists of a novel concrete mixer, wherein novel means are employed for loading it.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description of my invention.

For the purpose of illustrating my invention, I have shown in the accompanying drawings a typical embodiment thereof which is at present preferred by me, since the same will give in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents in side elevation a portion of a concrete mixer embodying my invention;

Fig. 2 represents a top plan view of a portion of Fig. 1.

Fig. 3 represents a section on line 3-3 of Fig. 1.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed December 30, 1916. Serial No. 139,760.

Fig. 4 represents a section on line 47-4 of Fig. 3.

Fig. 5 represents, on an enlarged scale, a top plan view of one of the interlocking rails.

Fig. 6 represents a section on line 6-6 of Fig. 5.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to. the drawings 1 designates a concrete mixer, the construction of the mixing and distributing mechanism of which may be of any desired type. 2 designates the bucket, which is pivoted in the usual manner as at 3, so that the material will be discharged into the hop per or chute 4. The lower end of the bucket 2 carries in any desired manner the trackforming rails 5, which at their inner ends are upwardly curved, as at 6, to form a stop or abutment for the front wheels of a car 7. It will be seen from Fig. 1 that the trackforming rails 5 are reversely inclined, that is, the rear ends of the rails incline upwardly and the forward portions of the rails incline downwardly, and these rails are attached to the bottom of the bucket 2-.

The reinforcing bars 8 of the bucket 2 are connected to a cross-bar 9, see Fig.2, and these reinforcing bars 8 are connected tothe upright bars 10, which are connected to the track-forming rails 5. The bars 10 have connected therewith the brackets 11, to which are secured the cables 12, which pass to the hoisting drum of the mixer, which controls the raising and lowering of the bucket 2. The track-forming rails 5 have fixed thereto a bar'13 which extends upwardly and laterally, as will be understood by reference to Fig. 3, in order to receive the hook 14, which is carried by the bottom of the car 7 in any desired manner, so that when the bucket is elevated the car will be held in operative relation thereto throughout the dumping movement.

15 designates a track which is portable and which extends into proximity to the material which is to be handled. This track 15 has connected therewith a bracket 16, into which the rails 5 extend when the bucket 2 is lowered. These brackets consist of U-shaped casings 17 which are secured to the web of the rails of the track 15 by means of fastening devices 18, and to the base flanges of the rails of the track 15 by means of fastening devices 19. vIn. concrete.

mixers now' employed, they are; self-propelled and move on the road as the work progresses by means, of their own power,

and when the mixer ismoved, the track 15' car is held to the rails 5 by the hook or clamp 14. When it is desired to dump the car, it is simply necessary to effect the upward movement of the bucket 2 in the usual manner and the material in the car 7 will be emptied into the bucket 2 and be discharged therefrom into the chute 4".

It will be apparent that concrete mixers now in use can be readily and" economically changed in accordance with my present invention, since the ordinary bucket can be cut away,- as will be understood by reference to Fig. I, and therails attached in positionand provided with the necessary braces to 1 rigidly connect them with the bucket.

It will be seen from the drawing that each caris provided with a spout 20' which fitsinto and conforms to the shape of the juxtaposed portion of" the bucket 2.

In the operation, as a car is filled, it is moved along the track 15' and passes up the inclined portion ofthe track-forming rails 5, and the front wheels abut against the curved portion 6 of the rails. The clamp 14 interlocks with the bar'13; The cable 12 is then raised, thereby turning the bucket 2'on itsfulcrum- 3, and the cross-bar2l' aids insecuring the car 7 in position. The material in the car discharges through the bucket '2' into the chute 4. The bucket 2'is then lowered, the empty car is rolled out of the bucket into position for reloading, the other car which has been loaded is then rolled into the bucket 2 and automatically clamped. in position, and, the operation above described is repeated.

It will be apparent from the foregoing that I have reduced to. a minimum the cost of charging the concrete miXer with the aggregate since I have dispensed with a number of the men which have heretofore been deemed indispensable.

Having thus described my invention, what I claim as-new and desire to secure by Letters Patent, is

1. In a concrete mixer, the combination with anupwardly swinging charging bucket having an open bottom, of rails extending across said bottom and secured to said bucket, a carto engagesaid rails and having a spout to discharge into said bucket, and interlocking means common to said bucket and car;

2. In-means for thepurpose' described, the combination ofa bucket mounted for bodily upward swinging movement, rails carried by'and bodily movable with thebucket and" extending therefrom to be in substantial horizontal position upon the ground when the bucket is lowered the saidextended" portions of the rails being reversely inclined from intermediate points in the length thereof, a cararrangedtorun-upon-said extended portions of the rails into such juxtaposition to the bucket as to discharge its contents into and through the bucket when the bucket and car are swung-upwardly,
