s claims.l (Glisse-vs) l My inventionrelates to improvements in mixing machines and has for an object thereof to provide a simple anddurable heavy duty device-of the present nature which will function in a highly efficient manner to mix substances such paint and the like while contained in closed barrels or other relatively large receptacles.

Another object of the invention is to supply a heavy duty mixer having a cradle equipped with clamping means for conveniently receiving barrels and the like of various forms and rmly holding them in place within the cradle.

Afurther object of the invention is to provide means disposed beneath vthe cradle and having parts underslung therefrom for imparting a rocking movement to 'said cradle.4

An additional feature of the invention resides in constructing the cradle from sheet material and in reinforcing the same by means of barrel 'checks and/or the cradle rocking means'.

.With the foregoing and other objects in view, which will appearin the 'following description, the invention resides' in the novel combination and arrangement of parts and inthedetails of construction hereinafter described yand claimed.

vIn the drawings:

Fig. 1 is a' side elevational View of a mixer embodying my invention; Fig. 2 is a fragmentary planview thereof ;vv Fig. 3, is an `end elevational view of the same, portions .of the structure being broken away to reveal parts that otherwise would be concealed, and Fig. 4 is a central sectional view taken on the line -l of Fig. 3.

Referring to the drawings, wherein similar parts are designated by similar reference characters throughout the several views, it will be observed that the illustrated embodiment of my invention includes a frame consisting of a base I0 to which a pair of standards il are secured. Supported upon said standards Ii and disposed between them is a cradle indicated in its entirety b-y the reference'character A. This cradle A. is channel-like in form and preferably bent up from sheet metal to provide a web I2 and upstanding side danges I3. Trunnions I4 issuing from the side `flanges I3, are rockably mounted -in bearings i5 on thestandards Il.- These trunnions are formed with attaching plates I6 at their inner ends Aand said plates are secured to the sidey flanges I3 ofthe cradle by means of bolts I'l.

Cradle rocking means are interposed between the base Iii and the web l2 of the cradle A, said means being, in part, underslung from said web I2 and, in part, mounted upon said base lil. Included in said cradle-rocking means is' a plate I8 having spaced lever arms I9 depending there- `from and braced with respect to said plate by means Vof reinforcing ribs 22. Thisplate i8 is substantially coextensive With the web' I2 and fis secured thereto by means of bolts 2I`. Cast i integrally with the base 'IIl are two bearing posts 2 2 in the bearings 23 of which a drive shaft 24 isv journaled. On this drive shaft 24 is an eccentric 2 5 and fitting this said eccentric 25 is a block 25 which slides in the way 2!` formed between the'i .two lever arms I9.

A pan 28 rests on the base I il, each side of said pan occupying a position between one of the bearing posts 22 and the. adjacent edges of the depending lever arms I9. This panZB Yfreely receives said lever arms I9 and is adapted to contain oil into which said arms dip, the splash ofthe oil by said arms serving to `lubrlcate the Vbearing surfaces of the eccentric 25 andthe eccentric block 26 and the bea-ring surfacesof said eccentric block and the lever arms 19. The bearings: 23 on the posts 22 have bearing caps 23a". which admit of the application of the power shaft 24 to said bearings 23 after the oil pan is placed vin position between said bearing posts 22. Any suitable means may be Vprovided for rotating the power shaft 24, it being my preference to mount a suitable power unit on the base lll and connect it with a sprocket 29 or the like on `s aid power shaft.

Disposed within the cradle .A` and upon the web i2 thereof are a pair of barrel chocks 30. The

bases of `-these checks conform with and abut thel upper surface of the web II2 and the ends of said surface rportions of the side flangesI I3 of the cradle. Said checks are bolted to the web I2 by means of bolts 3l, which preferably extend through the plate It of the driving means and ychoc-irs conform with abut the adjacentv -The cradle A is suppliedwith side clamps B,"

one for each chock 32. Each side clamp includes a pair of rods 32, each rod being pivoted toene of the cradle flanges i3 near the end of the cradle occupied by yoke to `bring it to bear uponthe upper .sideiof a its `respective chock. Slidably rrnormted at its ends on said rods is a yoke 3ft," said .rodsbeing threaded at their extremities and supzplied with hand nuts 35 cooperating with the 55 barrel and clamp the barrel down against said chock.

The cradle A is also supplied with end clamps C, each of which includes a pair of threaded studs 36, each stud issuing from the end of one of the cradle flanges I3. A clamp bar 37 is slidably mounted at its ends on the studs 36 and hand nuts 38, threaded on said studs, cooperate with said clamp bar 3l to releasably clamp the same against its respective end of a barrel supported in the cradle A. At either side of said cradle A is a strap 39 which is bolted or otherwise suitably secured to its corresponding cradle ange i3. Each strap 39 is preferably integral with the opposed clamp studs 36 at the same side ofthe cradle and constitutes an eiective tie between said studs, whereby the side anges I3 of the cradle are relieved fromthe strains incident to the binding of the clamp bars 3l against the Iends of a barrel.

In preparing the machine for the reception of a barrelcontaining material to be mixed, the side clamps B are swung down into the position shown in Fig; 4, wherein the rods 32 rest upon the hand nuts 38 of the end clamps C, said hand nuts 33, in such case, being retracted to permit the corresponding retraction of the clamp bars Eil'. A barrel 40, such as that indicated in dotted lines, is hoisted over the cradle A and lowered into position upon the chocks 3G. Thereafter, the side clamps B are swung upwardly into the position, as shown in Fig. l and Fig. 3, and the hand nuts 35 thereon are turned down to tighten the yoke 3d against the upper side of the barrel and thereby rigidly secure it in position'upon the chocksiii.v Then, the hand nuts 38 of the end clamps C are tightened to bring the clamp bars 3l rmly against the ends ofthe barrel to preventy endwise movement of the barrel in the cradle A. With a barrel iirmly secured within the cradle A, power is applied to the shaft 24 for rotating the same. As said shaft Irotates, the eccentric 25, through the medium of the eccentric block 25, imparts alternate thrusts upon the lever arms l 9 ofthe cradle A, thusI causing said cradle to be rocked back and forth. This oscillation of the barrel agitates the contents thereof and thoroughly mixes the same.

The iitting of the chocks 30 to the cradle A and the clamping thereof to the web I?! of said cradle reinforces said web and so also does' the clamping of the plate i8 to said web. This reinforcement of the cradle A by means of the chocks '30 and/or plate i8 permits' the use of relatively light material in the construction of said cradle.

The checks Bil are of wood or the like, while the yokes 34 and clamp bars 3l are respectively supplied with liners 34a, 37a of similar material. With said parts thus constructed, a barrel is 'nciselessly held within the container and is electrically insulated, this being an important fealture especially in the event of the application to lthe-machine of metallic barrels whose contents are of an explosive character.

The long leverage employed in the application of rocking forces to the cradle results in a highly efficient machine of quiet operation and long life. Changes in the specific form of my invention,

` as herein disclosed, may be made within the 'scope of what is claimed without departing from the spirit of my invention.

Having described my invention, what I claim as new and desire to protect by Letters Patent is: l.
