Specification of Letters Patent.

Patented Dec. 6, 1910.

To all whom it may concern.

Be it known that I, ALVIN FLAVEL NIMs, a citizen of the United States, and a resident of Philadelphia, in the county of Jefferson and State of New York, have invented a new and Improved Mixing-Machine, of which the following is a full, clear, and exact description.

This invention relates to machines for mixing concrete and similar material, and relates more particularly to a mixing machine comprising hollow, communicating sections arranged so that they can be revolved, and having an inlet and an out-let, partitions being provided within the sections, which serve to direct the material passing through the same.

An object of the invention is to provide a simple, strong and efficient machine of the class described, in which concrete or other material can be thoroughly mixed, which can be operated continuously or intermittently, which is so constructed that none of the material can escape accidentally, and which is further so constructed that it is impossible for quantities of the material to collect and remain at any point of the machine.

A further object of the invention is to provide a machine of the class described in which the material can be permitted to remain in the machine for any desired length of time, or can be released at intervals or at any time deemed proper, and which includes means for supplying liquid simultaneously to all of the compartments, or to any particular compartment or group of compartments.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which-- Figure 1 is a side elevation of an embodiment of my invention, having parts of the compartment or section broken away to show the interior thereof; Fig. 2 is an elevation of the discharge end of the machine; and Fig. 3 is a plan view showing the compartments or sections in broken outline, with the partitions therein in full lines.

Before proceeding to a more detailed explanation of my invention, it should be clearly understood that the present form of the device constitutes an improvement upon the mixing machine shown in my United States Patent No. 851,553, dated April 23, 1907. The mixing machine illustrated herewith is similar in form to the patented type, consisting of two or more rectangular, preferably cube-shaped sections or compartments, communicating interiorly, and mounted so that they can be revolved.

The improvements consist mainly, as will appear hereinafter, in the partitions arranged within the sections, which serve to direct and guide the material passing through the machine.

While the invention shown for example, comprises two sections or compartments, any desired number can be employed.

Referring more particularly to the drawings, I have shown a suitable support-ing frame 10 of timbers or the like, and having cross beams 11 provided with bearings 12 in which are journaled parallel shafts 13, only one of which is shown. One of the shafts 13 has a pulley 14;, which, together with a suitable belt 15, serves to connect the machine with a motor or other source of power. Uprights 16 mounted upon the frame, carry the feed hopper 17 having an outlet chute 18 through which the material to be mixed can escape to enter the mixing machine proper. This comprises two sections or compartments A and B of rectangular form and preferably cube-shaped. The sections may be fashioned from cast or sheet metal, or from any other material adapted for the purpose. The inlet section A has one corner cut away and provided with an inlet 19 preferably circular in form and having the chute 18 of the hopper l7 projecting into it, so that the material passes directly from the hopper into the section A. The sections are inclined with respect to the horizontal, and each has associated there with an annular rim or guide 20 supported upon suitable rollers 21 carried by the shafts 13 so that the machine can be revolved in the usual manner. The sections A and B are cut away at adjacent corners and are integrally or otherwise suitably connected. I prefer to provide the sections of the present form of the device with rounded corners instead of angular-corners, as in the earlier machine. The communicating openings of the sections A and B are rectangular, and each involves approximately a quarter of each of the surfaces forming the corner which is cut away. The lines of intersect-ion of the cube-shaped compartments are parallel to edges of the compartments as is shown most clearly in Fig. 1 at a and b.

Vithin the section A is located a wall or partition 22 extending entirely across the compartment and arranged at a slight angle with the opposite faces of the compartment between which itis located. The partition extends across the compartment between the inlet opening 19 and the outlet opening into the compartment B, and is cut away at one end to form an opening .23 so that material can pass through the same to the other compartment. As a result, the com Jartment is substantially L-shaped-and is cut away along two lines extending at right angles from substantially its center to edges, and parallel respectively to the remaining edges. The partition has an extension 24 substantially triangular in form and at right angles to the body of the partition. It extends along one of the lines at which the partition is cut away and is substantially parallel to the surfaces with which the partition is at right angles. The extension 24 is disposed toward the openings between the compartments A and B. One of the sides of the compartmentA with which the extension 2st is parallel, is extended through the commu nicating openings of the compartments A and B into the compartment B to form a guiding partition 25. This partition 25 is at substantially right angles with the partition 22 and extends over an edge of the same as is shown most clearly in Fig. 3. The partition 25 is substantially rectangular and has associated therewith at one end an upwardly disposed wall 26 forming a second partition within the compartment B.

A chute 27 is positioned within the compartment B and extends through the outlet opening 28 of the compartment. It is joined at its inner end to the wall 20, as is shown most clearly in Figs. 1 and 2. The chute has at one side a laterally disposed flange 29 tapered from the outer end, toward the inner end of the chute. The chute, it will be understood, projects through the opening to the outside, and is preferably slightly curved in cross section as is shown in Fig. 1. The chute is preferably arranged at a small angle with respect to the. surfaces between which it extends, so that it is likewise at an angle with respect to the partition 25, as is .shown in Fig. 1.

The outlet opening 28 of the compartment B is formed by cutting away one corner of the compartment along diagonal lines 0 and cl of adjacent surfaces and along a line f of the third surface. The sides of the line f are at an angle and are slightly curved. The escape chute 27 with its flange 29-fits exactly against the angular edge 7.

A door 30 is provided for the outlet opening of the compartment B, and is pivoted at one side of the cube B, by means of a pin 30'. The upward movement of the door 30 is limited by contact with a suitable stop 31. I also provide a pipe 32 communicating with any suitable source of water supply and having a bifurcated-fitting 33 so that two branch pipes 3i and 35 can be connected with the main supply pipe 32, each branch pipe being provided with a controlling valve 36. The

pipes

34 and 35 lead into the body of the machine through the inlet opening 19, one pipe terminating within the cube A and the other within the cube B. The partition 22 at its center has a cutaway part 37 through which the water pipes extend. The arrangement of the water pipes, it will be understood, is similar to that shown in my patent above referred to. The chute 27 has an opening 27 for one of the pipes'.

In the operation of the machine, as the cube sections are revolved, the entering material will drop to the lowest point in 'the cube section A, tumbling from corner to corner, and will continue thus to change its position in the chamber until it escapes through the opening into the compartment B. The partition 22, with the extension 24:, serves to guide the material to the opening between the compartments. As the material tumbles about within the compartments, it is thoroughly mixed in the usual manner. The operation is continued within the compartment B until the material finally fallsupon the outlet chute 27 and escapes through the opening 28 of the compartment B. The partitions not only serve to guide and direct the material into the machine, but also assist in the mingling of the constituents thereof. The flange 29 of the outletchute prevents the material from escaping accidentally at the side and serves to direct it 011 to a further, fixed chute 38 by means of which it can be led to any suitable point, where it can be utilized, or from which it can be transported elsewhere.

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