APL'PABATUVS FOR TAPPING LIQUDS SUCH AS PAINT FROM RECEPTACLES.

Application led July 10, 1924. Serial No. 725,311.

To all whom it may concern: n

Be it known that I, Max Roaman, a citizen of the German Republic, and residing at Ratingen, Germany, have invented certain new and useful Improvements in Apparatus for Tapping Liquids Such as Receptacles (for which applications for patent have been tiled in -Germany October 26, 1922, and August 20, 1923) of which the following is'a specification.

My invention relates-to improvements in apparatus for. tapping liquids such as paint from receptacles, and the object of the improvements is to provide an apparatus by l5 means of which the paint. is stirred before being taken from the receptacle. so that the deposit formed at the bottom is first. mixed with' the body of the liquid and liquid of homogeneous composition is withdrawn from the receptacle and a waste of liquid deposited at the bottom is avoided. 'With this object in view I provide apparatus for withdrawing liquid by means of which the liquid is stirred a certain length of time be- '26 vfore it is discharged from the receptacle.

For the purpose of explaining the invention two examples embodying thesame have been shown in the accompanying drawings in which the same reference characters have $0 been used in all the views to indicate corresponding parts. In said drawings,

Fig. 1, is an elevation partly in section showing the apparatus,A

Fi 2,. is a sectional plan view taken on the lne 2--2 of Fig. 1 and showing the.

' stirring means, l

Fig. 3 is a sectional .elevation of the means taken on the line 3 3 of g- Fig. 4, is an elevation partly in section showing a modification` and Fig. 5, is a section taken on the line 5-5 of Fig. 4 and Showing the rotary pump.

In describing the invention reference will 46 be made to an apparatus for withdrawing paint from a receptacle. But I wish it to be understood that my invention is not limited to such use.

As shown in Figs. 1 to 3. my improved apparatus is mounted on a plate 1 adapted to be placed on and secured to the open top of a receptacle 2 containing thepaint. Any preferred means may be provided for fixing the platein position. To show what may be 55 done the plate is formed with arms40 re- Paint from ceiving clamping screws 3 adapted to enga e the receptacle from the side thereof. It will be understood that the type of the said fixing means and the size of the plate. 1 are different accordingr to the size 'and form of the receptacle. The plate 1 is fixed to the receptacle so as to close the same in an air tight manner and to prevent loss of paint and spoiling thereof by vaporization and access of air and impurities.

To the plate 1 a plate 41 is secured which is provided with a vertical-bearing 4 disposed axially of .the receptacle and providing a guide for a tubular shaft' 5 passed downwardly therethrough and into the receptacle to the bot-tom thereof` where it shows a conical end engaging the bottom and providing an additional support for holding the same axially within the receptacle. The bottom part of the shaft '5 carries a helical stirring member 6 and a transverse arm 7 provided with '

bottom stirring members

8, 9 and 10. As shown the members 8 are in the form of springs projecting downwardly and rearwardly from the arm 7 and into position for engaging the bottom of the recepacle.. the Imembers 9 are in the form of scratching members jointed to each other, and the members 10 consist of upwardly directed sheet metal plates adapted to retard the operation of the apparatus while stirring the paint. Thr` shaft 5 carries a collar 42 fixed thereto by .means of a. screw 12 and adapted to'be set in different positions for adjusting the shaft 5 in vertical position and' accommodating the same to receptacles of different heights: The shaft 5 is adapted to be rotated by means of a bevel gearing 13, 13, a shaft 43 mounted in -

bearings

44 and 45 rising from the plate 41 and a crank 14 secured to the shaft 43.

Within the tubular shaft 5 there is a nonrotatable pipe 15 secured at its top end by means of a screw 17 to an arm 18 projecting laterally from an upright .46 rising from the plate 41, and it is adapted to be ladjusted in vertical direction by means of the screw 17 according to the height of the receptacle. At its bottom the pipe 15 shows a check valve 47 and a plunger 16 provided with a check valve 48 and connected with a rod 19, s'aid parts providing a pump for taking paint from the receptacle. The connecting rod 19 is adjustably connected to a crank pin 48 provided on a crank disk 21 the shaft 49 11 bf whith is mounted in the upright 4.6. The

, connected therewith by means of a clutch that 24, 28, the member 28 being adapted 'to be shifted into coupling position by means of a centrifugal governor'49 provided with arms 27 en aging a disk 50 carrying the clutch member 28. vThe governor is con-4 fined within a casing 26.

The operation of the apparatus is as follows: For taking paint from-the apparatus the crank 14 is turned and rotary movement is imparted to the shaft 5 and thestirring

members

8, 9 and 10. Such rotary movement is transmitted through the gears to the shaft 23 and the governor 49. After the paint hasbeen stirred a certain length' of time the velocity of the apparatus is such the governor shifts the clutch member 28 into coupling engagement with the clutch member 24, whereupon the. pump 16 isoperated for raising 15, which paint Hows through a rockable gutter 20. If thevelocity of the operation isinsuiicient to' insure proper stirring of thel paint, or when stopping the pumping altogether, the governor 49 permits the member 28 to be disengaged from the member 24, whereupon the operation of the `pump is interrupted. By4 enclosing the dispensed with, and

governor within the casing 26 the attendant is prevented from closing the

clutch

24, 28 by hand for taking paint fromy the receptacle without stirring the same. 7 In the modification shown in Figs. 4 and 5 the

clutch

24, 28 and the governor 49 are the pump is alwayls inconnection with the stirring and driving mechanism, stirring of' the paint being insured by providing a pump, such as a centrifugal pump, which raises the paint only after -the mechanism has assumed a certain velocity andthe paint has becomey suiiicient- 1y uent.

At its bottom end, the pipe 15 is formed vwith a casing 30-'having a discharge passage pr ov1ded with a bottom plate 36 :for

dlrectmg the liquid upwardly and into Athe pipe 15. Within the pipe there is a i rotary shaft 32 carrying blades 31 at its .y The shafts 5 crank bottom end, said casing, passage, 'blades and shaft providing a centrifugal pump takingthe liquid from the receptacle 2 and raising the same through the pipe 15. To the top end'of the shaft 32 a .pinion 33 is secured which 1s in mesh with a large `gear 34'keyed to the shaft 23.

and23 are driven from the 14 in the same way as` has'been dewith reference to Figs. Lto 3. For paintfrom the receptacle the crank paint through the pipe pump with said operating ,v

7. In an. apparatus of theclass described,

means, and 13 14 is turned andthe shafts -5 and 23 are rotated. At first the paint is merely stirred and not raised by the pump 31. As the" paint becomes iuent by stirring the resistance opposed to the stirring mechanism isA reduced andthe speed-of the mechanism and the pump is increased, until it. is vsutiicient to raise paint through the pipe 15. Shouldv theattendan't fail to turn, the crank 1 4 f ast enough the discharge of paint is interrupted, so that the paint can be'taken from the receptacle only after being suiiciently stirred. While in describing thel invention reference has been made to particular examples embodying the same I wish it to be understood that myA invention is not limited` to the constructions shown in thevdrawing, and that various changes may be made in the general arrangement of the apparatus and` the construction of its parts withoutv departing from the invention'.
