NETE@ STATES JOHN' R. FISH, OF WEST SPRINGFIELD, MASSACHUSETTS.
AGITATOR.
Application filed March 29, 1922.
To all 'whom it may concern:
Be it known that I, JOHN R. FISH, a citizen of the United States of America, residing at West Springfield, county of Hampden, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Agitators, of which the tollowing is a specification.
This invention relates to improvements in agitators and particularly to devices Jfor mixing paint and other viscous liquids in which a sediment or settling of the mixture occurs in the bottomtpart otl the receptacle.
At the present time some of the devices in use for mixing and stirring paint are attached to the barrel when they are filled and ready orshipping. This method is objectionable in that the blades which are used for `mixing or stirring the paintbecome so rigidly embedded in the bottom of the barrel caused by the settling of the mineral part of the paint, that oftentimes the mixing device will break when an attempt is made to use the mixer for stirring or mixing the paint in the bottom of the barrel. My present improvement is designed to be readily inserted into the barrel or can after the receptacle containing the paint is shipped. In this way all danger of breakage of the mixing device is eliminated and furthermore it may be readily inserted and removed from the barrel, or can when not in use and therefore the same device may be employed in mixing or stirring the paint in other barrels.
Broadly my device comprises a rod or shaft Vhaving suitable means for rotating the same which rod is provided at its lower or outer end, with la propeller like or stirring device that is pivotally connected thereto. One end of the propeller device is made heavier or over-weighted, whereby when the rod is drawn upward out of the paint in the barrel the propeller will automatically turn or rotate on its pivotal support and assume a position that is substantially along side of and parallel with the rod permitting theoperator to readily remove the device as a whole through the opening which is cut in the upper or one end of Vthe barrel. The device is designed to be used in wooden barrels or tin cans in which paint.l isl often shipped. w@
Referring to the drawingsr* ww Fig. 1 is a vertical sectional viewthrough the axis of thebarrel showing `t-he interior Serial No. 547,718.
thereof with the device inserted therein, the full lines indicating the position of the propeller when in use and the dotted line when it is inserted or removed from the barrel.
Fig. 2 is a detail view showing the pivotal connection of the propeller with the stirring rod or stati which rod is formed with a sharpened inner end and Fig. 3 is a detail view illustrating the method of attaching the device to the receptacle or tin container.
Referring to the drawings:
1 designates the barrel or cask having the usual heads 2 and 2'; 3 indicates the oil which naturally assumes a position on or above the mineral settlings of the paint which is indicated at 1l. The line or strata between the oil and the mineral part ofthe paint being indicated at 5. The device in detail comprises a rod or shaft 6 having an offset or crank portion 7 and a suitable rotatable knob 8 similar to a bit brace. Located 0n the rod 6 is a slidable and rod adjusting collar 9 and a set screw 10 for rigidly clamping the collar to the shaft in different positions. 11 indicates a threaded plug or nut having an opening therethrough for receiving the rod 6. This rod is formed with the tapered threads 1Q and the flange part 13, which engages the upper or outer end of the head 2 and forms a tight joint with the head. An opening is formed in the head into which the tapered threads 12 embed themselves. The lower end of the rod 6 is formed with a sharp end indicated at 1li for entering the wood of the bottom 2 for providing a bearing for the rod. Pivotally connected to the lower end of the rod 6 is a propeller or agitator having oppositely extending blades 15 and 16,the pivot being indicated at 17. 17 is a nut :tor securing the propeller in place. One end of the propeller is over-weighted by means of the additional plate 18 whereby when the rod 6 is drawn upward, as indicated by the arrow 19 the propeller or agitator will turn on its pivot and automatically assume the position indicated in dotted lines, whereby the Iagitator asa whole may be withdrawn from the barrel through the opening in which theclosure plug 11 is located. In operation, the user inserts the agitator through this opening and adjusts andsecures the collar 9-on the rod 6 by means of the set screw 10. It engages the upper surface of the plug 11. This will limit the downward position of the agitator blades and after the paint is more thoroughly mixed the blades may be lowered from time to time by readjusting the collar 9 until the point 14 engages the head or bottom 2; whereby the rotation of the blades l5 and 16 will cause the oil and the mineral part of the paint to flow in the direction indicated by the dotted lines 2() thus thoroughly mixing the contents of the barrel. The opening through the plug 1l causes the shaft 6- to assume a vertical position by reason-of the bearing in the opening of theplug and when the shaft 6 is lowered to the full extent the sharp part 14 provides an additional `bearing on the surface.
Referringto thel detail shown in Fig. 3 in which 21 indicates one end of a tin can which may be used for the container. The nut 22 is formed with the curved or annular cut-out portion 23 and a tapered threaded portion Q4. The annular portion 23 causes the tin at the edge of the opening to be crimped or bent as indicated at 25 thus effectuall'y closing the opening in the tin. In order to guard against any leakage a gasket or washer of suitable backing material 26 is inserted between the upper surface of the tin plate and the flange part of the nut or plug 22.l
One of the advantages of the structure is that it may be inserted through the opening of the head and readily withdrawn without taking the device apart and reassembling it inany way.
`It is to be understood that when the propeller blades reach the bottom part of the barrel they will immediately assume the horizontal position as shown. It should be observed that the threads of the tapered threaded plug 22 merge into the annular groove 23.
lVhat I claim is:
l. In an agitator, the combination, of a shaft, alplug having an opening therethrough to receive the shaft, said plug being, designed to enter an ope-ning in the head 0f a barrel, two connected agitator blades pivotally connected to the shaft, one end of one of the blades being overweighted for causing the two blades to automatically assume' a position parallel with the shaft, whereby the agitator may be removed from thebarrel'through the opening in which the plug is located.
