CONCRETE MIXER Filed April 6. 1932 2 Sheets-Sheet 2 Invenlor Jamel Jfra'ca,

flzwaorizw Patented F eb. 20, 1934 UNITED STATES PATENT 3 Claims.

My invention relates generally to mixers and particularly to devices for mixing into usable form, mineral aggregates, and water, and the like, whereby to form building material, concrete and the like, which devices are operable either by power or by hand.

It is an important object of my invention to provide a simple and easily constructed device of this character which is distinguished by low cost and efiiciency in operation.

It is also an important object of my invention to simplify devices of this general nature, and to give them more efiicient operation and render them capable of superior results, while reducing the effort and cost involved in the operation thereof.

Other objects and advantages of my invention will be apparent from a reading of the following description, taken in connection with the drawings, wherein for purposes of illustration 1 have shown a preferred embodiment of the invention.

In the drawings:-

Figure 1 is a general side elevational view of said preferred embodiment.

Figure 2 is a top plan View of Figure 1.

Figure 3 is a sectional elevational view from one end of Figure 1. I

Figure 4 is a horizontal sectional view through Figure 1.

Referring in detail to the drawings, wherein like numerals refer to like parts throughout the same, the numeral 5 generally designates the mixing receptacle and the numeral 6 generally refers to the rocker support therefor whereby the receptacle 5 may be given the desired rocking motion for turning over and mixing therein a charge of concrete forming materials or the like and water or other fluid.

The receptacle 5 is of generally rectangular elongated box-like formation provided with a comparatively narrow transversely elongated opening 7 disposed centrally and intermediate the ends of the top of the receptacle. One side of the receptacle is angularly and outwardly expanded as indicated at 8 and in this side there is provided a spout structure 9 for discharging the contents of the receptacle. The spout has the top plan view seen in Figure 2 and is composed of convex walls 10 having an upward inclination as shown in Figures 1 and 2. The upper edges of the walls of the spout slope downwardly and outwardly as indicated at 11 to a level below that of the top of the receptacle.

At each end of the container the end wall is semi-circularly curved as indicated at 12 and 13, and the side walls 14 and 15 of the recep tacle are appropriately curved and connected to the

ends

12, 13 by welding or other suitable construction. The curved ends of the receptacle are provided properly shaped andpropor tioned so that when there is a concrete mix in the receptacle it and the ingredients thereof will be thrown toward one end thereof when the receptacle is rocked and thrown upwardly and inwardly and turned over and when the receptacle is rocked in' the opposite direction,

1 mm jgif The rocker structure 6 comprises a pair of semi-circularly curved bars 16, 17 transversely spaced and extending at either end to a point at either end of each longitudinal side of the receptacle near the inward terminals of the

curvate portions

12, 13. Each end of the rockers 16, 17 has a vertically projecting

member

18, 19 and 20, 21. These vertical members are connected in any suitable manner to the outside of the longitudinal sides of the receptacle and extend thereabove as indicated in the drawings, whereby to constitute handles for manually rocking the device of the invention when employing it for mixing concrete or the like, and for assisting in the tilting of the device for discharging concrete or the like therefrom from the spout 9. i

The semi-circularly curved rockers 16, 17 may be formed of round stock and the vertical mem-,

bers 18, 19 and 20, 21 formed by flattening end portions of such round stock.

Vertical braces

22, 23 are connected between middle portions of the rockers 16, 17 and the bottom of the receptacle, and between these

braces

22, 23 and connected thereto at upper and lower portions thereof are crossed brace bars 24 which have their ends angularly turned and secured as indicated at 25 to the said portions of the

braces

22, 23, whereby to give the rocker structure rigidity adequate for requirements.

It is important that it be understood that when the sand, cement, and water of a typical concrete mix or the like is placed into the receptacle through the opening 7, the mix will be properly agitated and mixed when it is caused to run alternately to one end and the other of the receptacle by rocking the receptacle, so that and any change or changes may be made inmaterials and in structure and arrangement of parts within the spirit of the invention and the scope of the subjoined claims.

What is claimed is: 1. A mixer of the type described comprising a closed receptacle having a flat bottom and vertically and inwardly curved ends, and provided centrally of its top with a relatively narrow transverse charging opening extending through one side of the receptacle, a discharge spout laterally extended from said side of the receptacle and in communication with the chargingopening, rocker means for rockably supporting the receptacle, said mixer being rockable for throwing a charge against either curved end thereof for turning over and mixing the charge.

2. A mixer of the type described comprising a closed receptacle having vertically and inwardly curved ends, and provided centrally of its top with a charging opening, a discharge spout laterally extended from one side of the receptacle and in communication with the charging opening, rocker means for rockably supporting the receptacle, said mixer being rockable for throwing a charge against either curved end thereof for turning over and mixing the charge, said rocker means comprising a pair of curved elements having at either end an upper portion secured to the side of the receptacle, the upper portions being extended above the receptacle and forming handles for rocking the receptacle for mixing and for tilting the receptacle for discharging by the spout.

3. A mixer of the type described comprising a closed receptacle having vertically and inwardly curved ends, and provided centrally of its top with a charging opening, a' discharge spout laterally extended from one side of the receptacle and in communication with the charging opening, rocker means for rockably supporting the receptacle said mixer being rockable for throwing a charge against either curved end thereof for turning over and mixing the charge, said rocker means comprising a pair of curved elements having at either end an upper portion secured to the side of the receptacle, vertical braces connected between the curved elements and the receptacle, and crossed braces secured to and between the vertical braces.
