.5 Claims.
lMy invention relates to -a mixing machine that is particularly well adapted'to v`be used.as ;a
paint mixer for subjecting cans Aor Vreceptacles containing paintto complex .movements to eiliciently Vmix the paint in said receptacles.
My present invention is, in .some respects, an improvement on devices disclosed in my lprior patent on a Mechanical movement, No. 2,246,689, issued June 24, 1941.
An object of this invention is to -provide `a simple and eicient mixing machine that is adapted to receive and hold a receptacle, such as a can ci paint, and to impart to said can of paint a 'combined swash .plate and oscillating movement that will quickly and efliciently mix any settled or separated paint pigment with .the liquid in said can.
Another object is toprovide a mixing machine of simple, elllcient and inexpensive construction that can be advantageously used for'mixing or agitating other liquids beside paint.
.Another object is to provide afmixing-machine 'having novel means for moving a lever in a .conical path and novel means for simultaneously oscillating said lever on its own axis.
Another object is to provide a power operated .paint mixing machine aof shaker type -which is substantially free fromivibrationfand noise.
Other objects of the `invention will beapparent -from thefollowing description taken in connection with the accompanying drawings.
AIn the drawings- Fig. lis a vertical sectional View of Va Apaint mixerconstructed in accordance with my-in-ven tion, parts being shown in elevation.
Fig. 2 is a View vpartly in section and partly in elevation of said paint mixer taken substantially on broken line 2-2 of '.Fig. VA1.
Fig. 3 is a fragmentary Aview in elevation of parts of the device looking in-the direction of broken line 3-3 of Fig. 1.
Fig. '4 is a view partly in sectionand partly in plan looking in the direction of broken line '4-4 of Fig. l.
Fig. 5 is a fragmentary sectional view taken substantially on broken line 5-5 -of Fig. l1.
-Like reference numerals designate like parts throughout the several views.
This .paint mixer comprises a housing', preferably of tapered cross sectional shape, as shown in Fig. 2. A lever 6, which may be'of cylindrical cross rsection like a shaft and which isfmounted for oscillation, is disposed within the housing 5 and extends `outwardly through a bearing 'member 1in the front end portion of rsaid:housng.
A ball .member .8 is `secured on the lever -6 and mounted lfor oscillation .fin Vthe bearing member 1. The ball member 8 can be made as a separate piece and pressed ,onto the lever 6 or itican .be made as an integral vpart of the lever .6. This ball member B vwill oscillatefreely in vthebearing 1 and will also prevent longitudinal movement of the lever 6. The bearing y'I is held iniplace by a cap TI' which is secured to the housing lby screws or any other suitable means.
The Yforward end portion of the lever v-6 .fits into a hub 9 of a cross yoke I0 and is secured to said hub f9, as by a taper pin II.
The cross yoke I!) is connected with apparatus for receiving and holding a receptacle, `such as a paint can, that is to be subjected to complex movements for the vpurpose of mixing the contents of such receptacle, such as paint .ina can.
The receptacle holding means comprises two spaced .apart plates I2 and I3, Figs. l andfl, which may be of duplicate construction and are adapted to receive therebetween alreceptacle., such as a paint can. The face of each plate and I3 that engages with the receptacle has a rubber pad I4 secured thereto to receive the end of receptacles of various sizes .and to securely hold said receptacles.
The plates I2 and I3 are .supported on twol spaced apart guide bars I5 and I6 and onya medially .positioned adjusting screwY .I'I, all, of which are carried by the cross yoke l0. The guide .bars I5 and I6 are slidably received in hubs I8 of the plates I2 and I3. The adjusting screw I1 is threaded through a similar -hub I9 of each plate I2 and I3. The portions o'f the adjusting screw I1 that engage with the respectiveplates I2 and I3 .are oppositely threadedas indicated in Fig. 1, so that rotation of the screw I'I in one direction will move the plates l2 and I3 toward and away from each other. l
The guide bars I5 and I6 and adjusting screw `II rare supported by the cross "yoke I0.
Taper pins 20 can be used to secure the guide bars I5 and I6 tothe-cross yoke I0. Thescrew` vI'I is preferably secured to the yoke I0 by twoA spaced apart pins 2| that operate in an annular groove 22 insaidscrew I'I. The pins 2l prevent longitudinal movement of the screw I I fbut allow said screw vto be rotated for the purpose of adjusting the plates I 2 and I3 toward and away from eachother. A crank 48 is provided for rotating the screw I1.
.The rear end portion of the lever 6 extends into a lsocket 23 thatis providedin an 'oifcente1--N positionin a flywheel 124 which `:functions-asa.
`pin or journal member 26 that is rigid with the frame 5. Preferably a bushing 21 is provided Within the hub portion of the flywheel 24 foi` rotary movement on journal 26. A cap screw and washer 49 can be used to secure the fly- The fiywheel 24 is wheel 24 on the journal 26.
4 46 and threading them into other threaded holes 41 in the frame.
When the lever 6 is moved in a conical path the shaft 3| will be angularly moved back and forth about the axis of the bearing pin 38. Obviously this Will impart a twisting movement or axial oscillation to the lever 6.
In the operation of this device a receptacle, such as a can of paint that has been kept in one position, as on a shelf, long enough for the pigment thereof to settle, is placed in this machine with its two ends in -contact with the pads I4 on.
driven by a V belt 28 that passes around said flywheel 24 and around a grooved pulley 29 on the shaft of a motor 30.
When the flywheel 24 is rotated it will cause the lever 6 to be moved in conical paths which have their apexes at a common point coinciding with the center of the ball member 8. This will impart a wabbling or swash plate movement to the two bars I5 and I6 and screw I1 which carry the plates I2 and I3.
Means are also provided for oscillating the lever 6 on its own axis at the same time said lever 6 is moved in conical paths. This lever oscillating means comprises an upright lever oscillating arm or shaft 3I having a forked upper end portion 32 that is connected by a cross pin 33 with the lever 6. Bushings 34 preferably are provided in the forked portions 32 of arm 3| for engagement with the pin 33. y
The arm 3I is slidably disposed in a bearing tube 35, which preferably Y has bushings 36 in which the arm 3l slides. Oil impregnated material 31 preferably is provided between the bushings 36 to insure proper lubrication of the bushings and arm 3|.
The bearing tube 35 has two oppositely-protruding bearing pins 38 and 38 integral therewith and extending at right angles therefrom. The bearing pins 38 and 38' are journaled in bushings 39 that are carried by bearing members 4U and 4I which are rigid with the frame 5. The use of two diametrically opposite bearing pins 38 and 38' with two bearings 40 and 4I on opposite sides of the tube 35 provides a very strong and substantial bearing structure for withstanding the strains to which the tube 35 is subjected. If desired, the bearing member 40 can be cast as an integral part of the frame 5 and the bearing member 4I can be bolted directly to the-frame 5 to provide a non-adjustable bearing. However the drawings show these parts as mounted for vertical adjustment.
It is preferable but notl essential to` have the bearing member 4D adjustably supported so that its distance from the lever 6 can be varied. Such an adjustment makes it possible to vary the angle of oscillation that will be imparted to the lever 6 as said lever is moved in a conical path. One Way of providing this adjustment is to provide, in the frame 5, a vertical slot 42 that slidably receives a boss 43 on a plate 44 that is integral with the bearing member 40. The plate 44 overlaps the frame 5 at the sides of the slot 42 and has vertical slots 45 therein. Cap screws'46 extend through the slots 45 and are threaded into the frame 5 to adjustably but rigidly secure the bearing member 4D to the frame 5. The slots 45 provide for a limited adjustment of the'bearing member 40 by loosening the cap screws 46 and moving the plate 44 up or down. Further-adjustment can be had by removing the cap-screws 'the plates I2 and I3. The screw I1 is then turned by'taking hold of the crank 48 on one end thereof, and the plates I2 and I3 are tightened or pressed against the ends of the can. This causes the ends of the paint can to be depressed into the pads I4 and the paint can will be held very firmly.
The'motor 30 is then started so as to rotate the flywheel 24 and move the lever shaft IIi in conical paths. This conical movement of the shaft 6 will impart a wabbling or swash plate movement to the yoke I0, and paint can holding parts carried thereby. At the same time the lever shaft 6 will be oscillated by the Vupright shaft 3| and this oscillating movement will be transmitted to the wabbling yoke I0 and paint can holding parts carried thereby. This will simultaneously impart to a can of paint a swash plate or wabbling movement and an oscillating movement and will quickly and efficiently mix any settled pigments with the liquids in the paint can.
The complex movement imparted to the receptacle held by the plates I2 and I3 is very eiicient in mixing the contents of this receptacle. Also the movement of the parts is very smooth and well balanced and it has been found that this machine will operate with substantially no vibration and with very little noise.
The foregoing description and accompanying drawings clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that changes may be made within the scope and spirit of the following claims.
