MIXER.

Specification of Letters Patent.

Patented Dec. 15, 1908.

Application filed August 28, 1907. Serial No. 390,454.

To all whom it may concern:

Be it known that I, ABNER M. MONDAY, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Mixers, of which the following is a specification, reference being had to the accompanying drawing.

My improvement relates generally to machines for mixing various commodities and particularly to apparatus for mixing the ingredients for concrete and similar compounds.

The object of the invention is to roduce a mixer which is adapted to be readl y moved from place to place for receiving the ingredients preparatory to mixing, and which is adapted to be carried from the place at which the ingredients are received to places at which the mixture is to be discharged.

The nature of the apparatus is such as to permit the mixing of the material while the apparatus is at the oint at which it receives the material or w ile the apparatus is in transit carrying the material to the place at which it is to be discharged.

In the accompanying drawings, Figure 1 is an elevation, partially in section, of an apparatus embodying my improvement; Fig. 2 is an elevation, also partially in section, of the same apparatus, the view being on a line perpendicu ar to the line of view in Fig. 1; Fig. 3 illustrates a modification of the apparatus, the view being similar to Fig. 1.

Referring to said drawings, 1 is a bail suspended from a tackle, 2, which is supported from a crane or derrick not shown. By means of said tackle and derrick or crane, said bail may be carried from place to place within the range of said derrick or crane. Any other lifting and carrying mechanism may, of course, be substituted for the ordinary crane or derrick.

Within the bail, 1, is supported a rectangular frame, 3, comprising two upper horizontal pieces, 4, two u right side pieces, 5, and a lower horizonta piece, 6. At each side of said frame is a journal, 7, extending through a bearing, 8, in the bail. One of said journals is extended through the adjacent bearing, 8, far enough to receive a worm gear wheel, 9, keyed to said journal. Above said worm gear wheel is a worm shaft engaging said worm gear wheel and resting in bearings, 11, and having at one end a hand wheel, 12. By turning said hand wheel, said worm shaft and worm gear wheel are turned, and this causes the turning of the frame, 3, on the axial line of the journals, 7; and the various parts supported by said frame, as herein- 1 after described, artake of the same motion. U on the lower rame piece, 6, are mounted ro lers, 13, said rollers being horizontal and transverse to the frame, 3, and having j ournals, 14, resting in bearings, 15. Each of said rollers is preferably recessed at its middle, as shown at 16 in the drawin gs, to receive the annular gear to be described later. A receiver, 17, is located within the frame, 3, and rests upon the rollers, 13. Said receiver may be of any form adapting it to rotate within the frame, 3. In the form shown in Figs. 1 and 2 of the drawings, the middle portion of said receiver is cylindrical while the portion at each side of said cylindrical portion is in the form of a truncated cone, and each end of the receiver thus formed is open. Around said middle cylindrical portion of the receiver is an annular gear, 18, which extends into the recess, 16, in the rollers, 13. Above the receiver, a s 111' gear wheel, 19, meshes with said annu ar cog gear and is mounted upon a horizontal shaft, 20, resting in bearings, 21, in the u per frame pieces, 4. Upon said shaft at eaci side of said spur gear, 19, is a spur cog gear, 22, meshing with the cog gear teeth, 23, on the spool-form Wheel, 24. Said wheel, 24, is mounted upon a shaft, 25, resting in bearings, 26, in said upper frame pieces, 4. It will be observed that the spur gear Wheel, 19, and the rollers, 13, prevent the receiver from moving in said frame transversely to the receiver axis, and it will be observed that by rotating the spur gear, 19, the receiver may be rotated upon its axis within said frame. To revent the movement of the receiver paralle to its axis, said receiver is provided with an annular shoulder, 27, at each side of the middle cylindrical portion of the receiver, and rollers, 28, mounted on axes radial to the receiver axis are made to bear against said shoulders. Journals, 29, for said rollers are secured to flanges, 30, on the upper frame pieces, 4, and flanges, 31, on the lower frame pieces, 6.

The material to be mixed is delivered into the receiver through either opening, 32, by any suitable means, as a spout, 33. The receiver is thenrotated by applying power to the spool-form wheel, 24. In the form shown in the drawings, this is done by means of a rope or cable, 34, surrounding the middle portion of said wheel frictionally and extending thence upward through a guide opening, 35, in the arch, 36 (supported by the upper pieces, 4), and thence over two guide rollers, 37, supported by the bail, 1, and thence to any suitable power mechanism (not shown) for drawing either end of said rope. Said power mechanism may be the same engine and accessories as are employed for operating the tackle by which the bail, 1, is lifted and carried. As a substitute for the rope transmission just described, electricity, compressed air, or steam may be used for actuating the gears involved in the rotation of the receiver. It will be observed that the receiver may be thus rotated upon its axis in either direction and at any desired speed and that such rotation may be carried on while the frame, 3, rests upon the ground or any other relatively stationary body, and that such rotation may be carried on while the apparatus is being lifted by the tackle, 2, and moved through the air toward or to the place of discharge. Making the frame horizontal at the base adapts it the better to rest upon the ground during charging and rotation and discharge of the material. From the inner face of the receiver, blades, 38, project at various angles and serve to more effectively distribute and intermingle the material to be mixed.

In operation, the apparatus is swung or carried to the place at which the receiver is to take its charge of material. There the material is introduced through either opening, 32. The receiver is then rotated as long as may be desired, either while the apparatus is in the same position or while it is being carried through the air to the place for discharging. The material may be discharged without changing the location ofthe apparatus or the apparatus may be first carried to any desired point. For discharging, the hand wheel, 12, is turned in the proper direction to tilt the frame, 3, and the receiver in the desired direction. After the discharge, said hand wheel is turned in the reverse direction until said frame and receiver are again in their normal positions. The worm shaft serves to lock the worm wheel whenever said shaft ceases turning.

In Fig. 3, a fiat annular band, 39, is located at each side of the annular gear, 18, and each such band is as thick as said gear, so that the rollers, 13, need not have the recess, 16. And in said Fig. 3, the annular shoulders, 27, are omitted and the rollers, 28, made to bear against the outer side faces of said bands, 39. And in said Fig. 3, the left hand end of the receiver is not in the form of a truncated cone. On the contrary, the cylinder forming the middle portion is extended leftward and terminates in an upright, closed wall, 40. In such modification, the center of gravity is leftward of the middle of the axis of the receiver, and the axial line of the journals, 7, is correspondingly shifted leftward. And in said Fig. 3, the spur gear wheel, 19, and the s ool-form wheel, 24, are merged into a sing e spool-form wheel, 41, having at one end spur gear teeth, 42, meshing with the annular gear, 18, a rope, 34, being applied to said wheel, 40, as it is applied in Figs. 1 and 2 to the wheel, 24.
