TANK AND AGITATING CONSTRUCTION FOR PAINT SPRAYING APPARATUS Patented Oct. 29, 1929 UNITED STATES} PATENT 'OFFIQE AUSTIN H.- DOWNS, OF NEWARK, NEW JERSEY, ASSIGNOR '10 ECLIIf SE AIR BRUSH COM- PANY, INC., OF NEWARK, NEW JERSEY, A CORPORATION OF NEW JERSEY TANK AND AGITATING CONSTRUCTION wIIEOR PAIN T-SiR-AYING APPARATUS Application filed January 23, 1928. Serial No. 248,725.

This invention relates to improvements in tank and agitating mechanismtherefor and is particularlyiadapted for apparatusof this character which is designed for and used in connection with paint spraying equipment.

The principal object of this invention is the provision of a tank or container of any size adapted to hold liquid to be sprayed or distributed under pressure and having an agitating mechanism provided within the tank, with means fordriving said agitating mechanism mounted on top of the tank.

A further object of this invention is the provision of such a structure in which the agitating means is securely and properly held in positionin the lower part of the tank and in' which the tube or pipe through which the liquid is discharged from the tank is also suitably held in position, these parts forming a single assembly.

Further objects of this invention include improvements in details of. construction and arrangement whereby an eflicient construction of this-kind is provided capable of commercial production and assembly on an eco nomical basis and also designed for and capable of performing the work required. a

To the accomplishment of the foregoing and such other objects as may hereinafter appear, this invention consists'in' the con struction, combination and arrangement of parts hereinafter described andthensought to be defined in the appended claims, reference being had to the accompanying drawings forming a partrhereof and which shows,

, merely for the purpose of illustrative disclosure, a preferred embodiment of my inven 'tion, it being expressly understood, however, that various changes may be made in practice within the scope of the claims with 'out'digressing from my inventive idea.

, In the drawings-' y v v Figure 1 represents what we may call a front elevation of a tank or container'constructed in accordance with this invention:

Figure 2 is a top plan view thereof. Figure 3 is a view taken for the main part in vertical cross section on line 33 of Figure L;

Figure Lis a perspective" view of the lid or cover for the tank or containeran'd the,

attached parts, which are positioned within the tank or container, including the agitating means and means for holdin the same in position,'and the discharge tu e or pipe i associated therewith.

Referring now to the drawings,the numeral 1 designates the body of the tank or container. This may be of almost any size and shape commensurate with the requirements of the work and is preferably of metallic construction and of sufficient strength to withstand considerable fluid or air presand bolt construction 6, which s pivotally mounted as at 'Z on the tank or container. Thisflidv or cover may also be provided with handles 8 for the purpose of lifting and ready removal;

This lid ncover is arranged to support agitating means, the fluid discharge .pipe, means for driving the agitating means and various pipe connections with-their attached parts, whereby air or other fluid pressure may be. supplied to the tank or container and to the instrument for applying the liquid, such as a paint spray gun, as, well as an air filter, gauges and valves of various kinds. top of, the lid or cover is provided with a plurality of upwardly extending studs 9 which are adapted to support the plate 10 in The I a position raised and spaced above the top surface of the lidor cover, 1011 this plate or" support 10 is mounted a motor 11, which in the form shown is an electric motor and has the driving bevel gear 12 secured .to theend of the drive shaft 13. Another and larger stud or boss lextends upwardly from another. part of the lid or cover 2 and receives at its upper end a bearing 15 which rotatably receives the shaft 16 for operating the agitating means. lhis shaft 16 has the bevel gear 17 on its upper end meshing with the driving bevel gear 12, as clearly shown in Figure 3. ihe shaft 16 extends through the lid or cover to near the bottom of the tank 'or container and has the packing gland construction 18 provided in the lid or cover to make the joint fluid-tight. lhe lower end of the shaft 16 has a bearing in the frame or plate member 19 and on its extremity has the agitating member 20 which is in the form of a multiple bladed propeller-like element. This frame or plate member 19 is positively and securely held in spaced relation to the various parts of the tank or container from the lid or cover 2 thereof by means of a plurality of rods 21 which are securely attached at their lower ends to the frame or plate 19 and at their upper ends are screwed into a substantial part 22 of the lid or cover. In the form shown this substantial part 22 is in the form of a raised, thickened portion and also acts to receive the packing gland construction 18 previously. described. I This frame or plate member 19 also serves as a means forholding-in proper relation to" the other parts the liquid discharge pip 23, the lower-end of-which fits through an opening in the plate or frame 19 and the upper end of which passes through the lid or cover 2 as at\ 24:. At the upper end of this liquid discharge pipe 23 are the connections 25 to which the other tubes, pipes or conduits are adapted to be; connected to convey the liquid to the point ofapplication, such as a paint spray gun or the like, as is well understood.

Referring more particularly to Figure 2, the numeral 26 designates an air or fluid pressure pipe having a connection with a suitable source ofpressure and 27 a filter thereon and 28 a continuation of 'this air pipe, which passes under the plate 10 on which the motor 11 is mounted; This pipe 28 has 4 one branch 29 in which is positioned avalve 30 and reducing valve 31 and a gauge 32, which leads through the lid or cover of the tank or container so as to apply suitable airor other fluid pressure to the tank or container and upon the liquid contents thereof, whereby its liquid contents will be forced through the liquid discharge pipe 23 under pressure when the liquid discharge valvein the applying instrument is opened. The pipe 28 has another branch 33 in which is positioned a valve 34, a reducing valve 35 and a gauge 36, andwhich has the connection 37 adaptedv to receive a hose, pipes or other con duits, which in turn are adapted to be conyes nected to the application instrument, such as .a paint spray gun" or the like.) These parts are all suitably mounted upon and supported on the lid or cover of the tank or container and, therefore, form a very conveniently arranged assembly for the control of the pressure; under which the apparatus is designed to operate, and to insure that the liquid in the conta ner, such as paint, lacquer and in fact any fluid or plastic substance, adapted to be applied under pressure, will be thoroughly mixed and agitated before being discharged from the liquid discharge pipe.

The assembly of the agitating means and the driving means therefor on the lid or cover results in a firm and secure construction for the agitating means insuring a direct drive for the same with the consequent agitation of the liquid and the supply of an even mixture through the liquid discharge pipe to the point of application. Not only that but the fluid discharge pipe is securely held with its inlet end nearthe agitating member and in a fixed relation thereto, with the obvious consequent advantages of everrmixture of the liquid.

The parts. are all easily made andjreadily assembled so that the apparatus forms an economically manufactured assembly having ,the many advantages of a much more complicated apparatus, convenient for transportation or portability and eficient in operation.
