On very small jobs, the best way to operate is to measure the concrete batch in layers of stone, sand, and cement respectively, and feed to the concrete mixer by men with shovels. There are two spray pipes placed on the concrete mixer: for feeding by hand, one spray only would be used; the other spray is intended for use only when operating with the measure and feeder, and a large amount of water is required. These sprays are operated by handles which control two gate-valves and regulate the quantity of water flowing from the spray pipes. These concrete mixers are made in two styles, sectional and non-sectional. The sectional can be made at a 4, 6, or 8 feet long. The non-sectional is in one length of 6, 8, or 10 feet. Both are constructed of 1-inch steel. To operate this concrete mixer, the materials must be raised to a platform, as shown in Fig. 123. Rotary concrete mixers, Fig. 124, generally consist of a cubical box made of steel and mounted on a wooden frame. This steel box is supported by a hollow shaft through two diagonally opposite corners, and the water is supplied through openings in the hollow shaft.

Materials are dropped in at the side of the concrete mixer, through a hinged door. The machine is then revolved several times, usually about 15 times; the door is opened; and the concrete is dumped out into carts or cars. There are no paddles or blades of any kind inside the box to assist in the mixing. This concrete mixer is not expensive itself, but the erection of the frame and the hoisting of the stone and sand often render it less economical than some of the more expensive devices are usually mounted on a suitable frame by the manufacturers. The rotating of the drum tumbles the material, and it is thrown against the mixing blades, which cut it and throw it from side to side. Many of these machines can be filled and dumped while running, either by tilting or by their chutes. Fig. 125 illustrates the Smith concrete mixer, and Fig. 126 gives a sectional view of the drum, and shows the arrangement of the blades. This concrete mixer is furnished on skids with driving pulley.

The concrete is discharged by tilting the drum, which is done by power. Fig. 127 represents a concrete mixer, which is a concrete batch concrete mixer. The concrete is discharged after it is mixed, without tilting the body of the concrete mixer. It revolves continuously even while the concrete is being discharged. Riveted to the inside of the drum are a number of steel scoops or blades. These scoops pick up the material in the bottom of the concrete mixer, and, as the concrete mixer revolves, carry the material upward until it slides out of the scoops, which therefore assist in mixing the materials. The figure represents a concrete batch mixer. In this concrete mixer, the lever on the drum operates the discharge. The drum is fed and discharged while in motion, and does not change its direction or its position in either feeding or discharging.

The inside of the drum is provided with blades to assist in the mixing of the concrete. Paddle concrete mixers may be either continuous or of the concrete batch type. Mixing paddles, on two shafts, revolve in opposite directions, and the concrete falls through a trap door in the bottom of the machine. In the continuous type the materials should be put in at the upper end so as to be partially mixed dry. The water is supplied near the middle of the concrete mixer. Fig. 129 represents a type of the paddle concrete mixer. Mechanical measuring machines for concrete materials have not been very extensively developed. One difficulty is that they require the constant attention of an attendant, unless the materials are perfectly uniform. If the machine is adjusted for sand with a certain percentage of moisture, and then is suddenly supplied with sand having greater or less moisture, the adjustment must be changed or the mixture will not be uniform.
