Patented May 3%, 1933 FRANK G. LEE, OF KANSAS CITY, MISSOURI, ASSIGNOR T STANDARD- OIL COMPANY;

OF CHICAGO, ILLINOIS, A COREORATION 0F INDIANA ALUll-IINUM PAIHT IYIIXER Application filed. September 20,1930. Serial No. 483,296.

This invention relates to an aluminum paint mixer. Aluminum pamt is used in increasing amounts in petroleum refineries and elsewhere; it is particularly useful in painting storage tanks and similar devices where a good reflector is required as well as a protective coating. Aluminum paint can: not be stored successfully in a ready mixed condition and it is therefore necessary to mix the aluminum powder with varnish or other vehicle as needed. Aluminum powder, being very light and finely divided, rapidly fills the surrounding atmosphere when mixed in the ordinary manner. In such cases there is not only an economic loss of aluminum powder, but there is a health hazard to painters and explosive hazard to the mixers. The object of my invention is to minimize these hazards and to avoid the loss of aluminum powder.

A further object is to provide a combination of mixer, container and measuring device whereby difierent containers may be selectively combined with the mixer and measuring device for completing a new and im proved combination. A further object is to provide means for securing the container to the measuring device. ther objects will be apparent from the following detailed clescription.

In practicing my invent-ion I couple a commercial aluminum powder can (container) to a drum-receiving hopper and seal the joint with a tight gasket. The hopper forms the upper partof a measuring or proportioning device which, in turn, is adapted to be tightly mounted over an enclosed mixing chamber. The package in which the powder is shipped (container) becomes a part of my combination and cooperates with the proportioning device and mixer whereby an aluminum paint of any desired quantity and proportions may be mixed in an entirely closed system without loss of powder. and without danger to workmen.

My invention will be more clearly understood from the accompanying drawing wherein I have shown an elevation of my improved paint mixer. This mixer may be mounted on asuitable support or table 10 paint outlet may extend therethrough and deliver the mixed paint to bucket 12 mounted on shelf 13, carried by cross arms-14,

which are, in turn, secured to table legs, 15.

The paint mixer may be a cylindrical vessel 16 having a tapered bottom 17 terminating in a discharge pipe 18 and valve 19.

The mixing mechanism may consist of a strap mixer 20 mounted on a shaft 21 journaled in bearing supports 22. A bevelled gear 23 is keyed to the end of shaft 21 and is driven by a bevelled gear 24, keyed to shaft 25 which is turned by a crank. 26. The other end of shaft 25 may be suitably jours 'naled by vertical support 27 mounted on the upper journal support 22.

The top of mixing chamber 16 is provided with a smooth, cylindrical flange 28 adapted to snugly fit telescopically into a similar flange 29 on mixer or proportioning chamber 30. This chamber consistsof a cylindrical vessel 31 of reduced diameter mounted on an inverted hopper 32. The vessel con tains a measuring hopper 33,-the outlet of which is regulated by a gate valve 34 regu-. lated by a suitable handle 35. A. similar gate valve 36 operated by handle 37 controls the admission of the aluminum powder from an upper hopper, the outlet of which is aligned with the central aperture 38 in gasket 39, which is secured to the opened end of container 40. The container 40 is physically supported by drum receiving hopper 41 which terminates in an enlarged upper cylinder 42. v

A suitable window (not shown) may be provided in the wall of chamber 30 and a suitable scale may be indicated on the hopper 33 so that the proportions of the aluminum powder can be accurately regulated.

The canvas gasket 39 is securely tied around the can or container 40, gate valve 36 is closed, the cylindrical end 42 of drum receiving hopper 41 is secured to the open end of the aluminum powder can over the gasket and the entire assembly is then inverted and telescopically fitted over the mixing chamber by means of

telescopic flanges

28 and 29.

A vehicle funnel 43 communicates with the mixing chamber through pipe 44 which enters inverted hopper 32 and which is provided with a suitable regulating valve 45.

5 The operation of the invention is apparent from the above description. The canvas gasket compensates for irregularities in sizes and shapes of containers or shipping packages,it is a means whereby any container may be tightly mounted over the measuring device without loss of powder. This gasket acts as a seal to prevent loss of powder, a packing to hold the container on the upper portion 40 of hopper 89, and a distributor for properly directing and feeding'the powder.

While I have described the combination for mixing aluminum paint, it is understood v that this apparatus may be used for mixing other ingredients,the container may be filled with a liquid instead of aluminum powder or it may contain any other substance which may be fed by gravity in amounts measured and regulated by the hoppers and gate valves above described or their equivalents.

The term container as used in the following claim is hereby defined as a receptacle in which a substance is marketed and transported as distinguished from a fixed part of a mixing machine.

I claim:

The method of making aluminum paint with a liquid vehicle and aluminum powder from a shipping container which comprises incorporating said container in a closed system and sealing the connection between the container and the system to prevent loss of aluminum powder, discharging quantities 40 of said powder from said container into said system through said sealed connection, measuring quantities 01 said powder in said closed system, depositing said measured quantities of powder into a mixing zone,

separately introducing a liquid vehicle into said mixing zone, and mixing the measured quantities of powder and liquid Vehicle thus embodied into the system.

Sugar Creek, in the county of Jackson, State of Missouri.
