MIXING AND GRINDING APPARATUS.

Specification of Iietters latent.

Patented Apr. 15, 1919.

Application filed November 26, 1918. Serial No. 264,228.

To all whom it may concern Be it known that I, ROBERT D. MADDOX, major, Med. Dept, United States Army, a citizen of the United States, stationed at Washington, D. 0., have invented an Improvement in Mixing and Grinding Apparatus, of which the following is a specification.

The invention described herein may be used by the Government, or any of its oiiicers or employees in prosecution of work for the Government, or by any other person in the United States, without payment of any royalty thereon.

This invention relate to apparatus for mixing, amalgamating, and grinding various substances or compounds, either dry, liquid, or semi-liquid, and has for one of its objects to produce an apparatus whereby the contents of a container may be thoroughly disintegrated and commingled by r0- tating the container, the latter being mounted upon rotating rollers.

Another object of the invention is to provide a container adapted to rapidly move its contents from end to end while being rotated. I Another object of the invention is to produce a device of this character adapted to support a plurality of independent containers with means for independently rotating them, and so constructed that the containers are loosely supported and adapted to be removed one at a time and replaced by other containers.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the inven-' tion Figure 1 is a side elevation.

Fig. 2 is a transverse section on the line 2-2 of Fig. 1.

Fig. 3 is an end elevation.

The improved apparatus comprises pri-. marily a receptacle for the material or product to be mixed or ground and mounted upon rollers disposed in spaced relation and rotated in the same direction, the receptacle being thus correspondingly rotated and the contents thoroughly mixed and commingled. The receptacles are preferably formed elliptical at the opposite ends with the longer axes at rlght angles to each other at the oughly intermingle and mix the same.

The receptacles may be constructed of any suitable material but will preferably be of glass, porcelain lined metal, vitrified ware, lead lined, or otherwise constructed to resist the action of acids or the like. For the purpose of illustration the receptacles, indicated at 10, are each formed with a contracted nozzle or mouth 11, having a suitable stopper indicated at 12. but it is not desired to limit the form of the containers or the material of which they are constructed. The rotating rollers may be of any required length and size and adapted to support any required number of the receptacles. Preferably the rollers will be arranged in pairs one-above the other and supported for rotation in a uitable framework. For the purpose of illustration a conventional framework is shown comprising vertical standards 13 of sections of I beams each with a laterally, constructed foot or base member 14, and laterally branching head members 15. The base members 14 are provided with'bearings 16 through which tie rods 17 are supported, while the head members 15 are provided with bearings 18 to support tie rods 19. The rods 17 and 19 are surrounded by tubular spacing members as indicated in Figs. 2 and 4. By this means the standards 13 are efl'ectually supported in vertical position and in. paced relation. The rotators may be of any required length to correspond to the number of receptacles to be employed.

The base members 14 are formed with bearings 20 to receive the journals of shafts 21. Attached to the standards 13 are bracket devices 22 each carrying a bearing 23 to support the journals of shafts 24. The standards may be of any required height to carry any required number of the brackets, but one set of the brackets only are shown for the purpose of illustration.

The shafts 21-24 support roller-devices 25, preferably of wood and each provided with a jacket or covering 26 of suitable yielding material. The yieldable ackets less chain 28 is disposed, and the shafts 24 are likewise extended at one end to receive chain wheels 29 over which an endless chain 30 operates. One of the shafts 24: and one of the shafts 21 are further extended to receive chain wheels 3132 over which an endless chain 33 operates. The shaft 21 which con tains the chain wheel 32 is further extended as shown in Fig. 1 to receive the rotating medium, notshown.

It will be obvious by this arrangement that when the last mentioned shaft is rotated by any suitable power the sets of rollers will be simultaneously rotated in the same direction through the action of the chains, and when the receptacles 10 are disposed upon the rollers as, shown, the receptacles will be rapidly rotated and cause their contents to be thoroughly mixed, ground, or commingled, as before described, and thrown from end to end at the same time.

The receptacles being disposed loosely upon the rollerscan be removed one at a time and replaced by other receptacles without disturbing the remaining receptacles. Thus compounds or material of various kinds may be operated upon at the same time and the contents of the various recep tacles separately retained. v e

The improved device may be employed for grinding or mixing various substances either powdered, liquid or semi-liquid, as may be required, and willbefound of's'pe'cia'l advantage in'grinding or mixing lymph or compounds employed in vaccination or inoculationsof various'kinds. The device may be 'Gopies Of this atent may be obtained 161' arranged for relatively large containers and likewise be employed for mixing concrete,

same direction, and a container resting by its side walls upon said rollers and rotated thereby, said container being elliptical at its opposite ends with the major axes of the elliptical portions at angles to each other.

3. In an apparatus of the-class described, a container elliptical at its opposite ends and with the major axes. of the elliptical portions at angles to each other and the sidewalls continuous from end to end.

4. In an apparatus of the classdescribed, a support including vertical standards in spaced relation, means for connecting said standards, a plurality of brackets connected to said standards at opposite sides and including shaft bearings, rollers having journals engaging in said bearings, means for rotating each pair of said rollers in the same direction, and 'a container restingjupon each pair of said 'rollers'an'd rotated thereby, said container being elliptical at its opposite ends, with the major axes of the elliptlcal portions at angles to eacho'ther,
