T0 all wiz/0m it may concern.-

Be it known that I, ALFRED WILLcox, a subject of the King of Great Britain, residing at 25 Norroy road, Putney, London, England, have invented certain new and useful Improvements in and Connected with Portable Mortar, Concrete, or Like Mixing Machines,of which the following is a specification.

The object of this invention is improvements connected with portable mortar, concrete, or like mixing machines whereby such machinery is rendered more efficient in action and the material more effectually mixed, the vehicle being so constructed that the sand, lime, cement, dac., are readily placed in the mixing-chamber and the Waterproperly supplied for a thorough Saturation, the material when thoroughly mixed being easily released for filling carts, barrows, trolleys, or the like for removal to the place required.

My invention Will be understood from the following description, aided by the accompanying drawingsin which- Figure l is a side sectional elevation of a complete machine. Fig. 2 is a side elevation of a complete machine. Fig. 3 is a plan of the machine with the water-trough removed.

For the purpose of my invention I construct a framework A on wheels B, so that the whole apparatus can be moved from place to place, and at the front and rear I'provide platforms O D, the center being occupied by a tank E, having the bottom shaped to form, so to speak, the segments ot two circlesV F G. In this mixing-tank E, I tit two axles H I at a distance from each other, these being provided With arms J, carrying blades K, so arranged that their edges have a travel in close proximity to the circular part of the Walls of the tank E, and such arms J are so arranged 'on each axle H I that during the4 revolving of such axles H I'the arms J follow one another in succession, the vaxles H I being geared together outside the tank by wheel L M, another gear-wheel N on the opposite side of the tank being in gear with a toothed wheel P on the pulley-wheel Q or crank-handle axle or other connection for the prime mover.

Above vthe center of the tank E is situated a Water-reservoir R, this carrying a perforated tube B, extending across the 'center of the tank E, the supply of Water being controlled by a valve T.

The center of the bottom of the tank E is formed by the apex of the two circular walls F G, and at this point I form a hinge-joint U, carrying doors V, forming part of the circular Walls F G, and such doors V are connected together by links W, controlled by a rod X from a hand-lever Y, so that on the operation of theVhand-lever Y in one direction the doors or flaps V can be opened to discharge the contents into a truck Z, (shown in dotted lines,) van, or other receptacle, and by a reverse motion of the handle Y the doors or flaps can be closed, these then forming part of the Walls F G of the circular portion and up which the beaters or mixer-blades K travel.

The portable apparatus can be secured in any desired position, and the mixer can be operated by hand or through a belt and .pulley or other gear from a stationary prime mover, or the prime mover may form part of the apparatus.

One platform C is providedwith a guide or track a for the barrow (not shown) containing the material to be placed in the tank or mixing-chamber, so that the barrow-load will be emptied in the same place in the tank E, the tank E being provided With a slope b to assist this operation, so that on the filling of the tank with the required proportion of each material, Whether it be sand and lime or cement or otherwise, a revolution of the arms J and blades K of one axle H will carry the material toward the center to the arms J and blades K of the other axleI, when it will be met loy the arms and blades of the second axle I to be carried onto the arms and blades of the first'axle H for a further movement, the material passing Vfrom vone set of blades tothe other until a thorough amalgamation takes place, the Water for making the material Wet to form the concrete or plaster being supplied at between the two axles II I from the perforated pipe S. On the thorough admixing of the material the operation on the lever YWill open the doors or flaps V in the bottom for discharge purposes.

The blades K are made with angled edges and with the front edge o of greater Width than the back d and are bolted to aright- IOO ' angled piece e of the arms J, so as to be easily H I, carrying arms J and bladesl K, gearwheels L M N Water-reservoir R, perforated pipe S extending across center of tank E, track a on platform C, and slope b in tank E, all arranged and acting substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing Wit- DGSSQS.

ALFRED WILLCOX. Witnesses:
