ATTORNEY S. B. BEUGLER MIXING MACHINE July 2, 1957 3 Sheets-Sheet 3 Filed May 13, 1955 INVENTOR Samuel 5. BEZIqZPI;
ATTORNEY? United States Patent This invention relates to a mixing machine of "the type employed in mixing paints by agitating or shaking containers thereof. 7
The primary object of the invention is to provide a machine ofthe above character which is rapid and thorough in its operation and in which the mixing action is effected by subjecting the container to a combined vertical or lateral swinging movement and a horizontal oscillatory movement in which the v ertical' swinging motion is accomplished on a pivotal'axis located below 'the'center of gravity of the container and its contents whereby the upper andlower end portions of the container will have diiferent relative movements or lengths of paths of travel, andin which the horizontal movement comprises short oscillations around the vertical axis of the container during vertical or lateral swinging thereof.
Another object is to provide a mixing machine in which a lidded mixing container is clamped and rigidly supported in a fashion such as to insure against spilling of the containe'rs content during the mixing operation, in
which the container may easily and quickly be'mounted in the machine and readily removed therefrom and in which the machine may be quickly adjustedfor the reception and working of containers of several sizes.
A further object is to provide a mixing machine embodying a container mounting capable of combined rectilineal rocking movement on a vertical plane and oscillatory movement on a horizontal plane, in which such movements of the mounting are eifected through the medium of a single revoluble crank, a crankarmfactuated thereby, and combined horizontally and: vertically pivoted supports for said mounting actuated through said crank arm, p v A With the foregoing objects in view together with such other objects and advantages as may subsequently"appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter-described and claimed, and as illustrated by way of example in the accompanying drawings in which:

- Referring to the drawings more specifically A indicates generally the-frame of the machine which embodies a opposite sides of the pivot 14.
The bar normally extends crosswise of'the' machine and is mounted onthe pivot 14 for short-oscillatory movement as will presently appear.
Mounted on the upper ends of the standards 16-16 is an upright rectangular frame D embodying parallelside rails 1717' and top and bottom end rails18 18', the'frame D being carried on aligned pivots a-=-a mounted 'on the standards" 1616 and engagingthe side rails 17-17 at opposed points located below the mean horizontal center of the frame D.
The upper end portion of the frame D is connected to the devergent end of a V-shaped crank arm E theside members bb of which extend astride the frame D andare' connected at their'ends c-c' to'the side rails 1717"'adj:acent"their upper ends by'aligned pivots dd as particularly shown in Figs. 3 and 4.
The convergent end 2 of the crank arm E iscon'nected through a ball bearing f with a crank g mounted on a horizontal disk 18 fixed on the upper end portion of a vertical rotary shaft 19-fitted with a pulley 20 carrying a driving'belt 21"'pas'singaround a pulley 22 on' the drive 'shaft 23 of a'rnotor F. The vertical axis of the shaft 19'exten'ds' on a plane extending through the vertical axis of the pivot 16 and on which plane lies the vertical center of the frame D.
Mounted for' vertical adjustment on' the frame D is a circular container supporting platform G having opposed *rail 18 but are adapted to be latched at different elevated slide-ways h-h' fixed on its margin which slidably eng'a'ge'guide ribs -i-i' extending longitudinally of the inner faces of the side rails 1717 of the frame D.
The slide-Ways I1-h' normally seat on the lower-end points on the side rails 17-17 as will be later described.
nected tothe' lower end of a threaded stem 24 which extends vertically through the top rail 18 of the frame D'in screw engagement therewith and is fitted at its-upper end with a crank 25 whereby the stem '24 may be manually rotated to'advance and retract the stem 24 and the disk H carried thereon.
The connection between the disk H and the stem 24 comprises an inverted socket 26 formed centrally of the disk and projecting from the upper face'thereof, which socket'consists' of a cylinder k formed with an inturned end flange 1 encompassing the lower end portion ofthe stem 24 which latter is formed with a flange m on its lower end projecting beneath the flange l. Pins n carried by the cylinder k extend beneath the lower-end of the stem 24 and form 'a'bearingbetween the -'stem-and"the disk H.
The platform G and clamping disk H are designed to receive therebetween a closed ended cylindrical container J constituting a receptacle of materials to be mixed; the
platform and disk having flanges 0' and p respectively engageable with the rims of the container ends.
Whiletheconstruction herein 'set forth is adapted to be'contr'ived for"tlie r'eceptionof acontainer'if ofany practical size, the machine here shown is intended for use in the mixing of paint in the usual gallon, half gallon, and quart cans, and accordingly the platform G and disk H are dimensioned to diametrically accommodate a gallon can with the end margins 'of which the inner peripheries of the flanges and p conform, and the spacing between the platform G and the disk H is such as to accommodate such can there-between when the disk H is in its near uppermost position. In order to adapt the machine for the reception of cans of lesser diameters than the gallon can, the platform G and disk Hare formed on their adjacent faces with opposed annular ribs qq' respectively diametrically dimensioned to conform to the peripheries of the ends of half-gallon cans, and are also formed with opposed annular ribs 1' and r dimensioned to conform to the ends of quart cans, the ribs qr and q'r being concentric with the aligned axes of the platform and disk.
In order to adapt the machine to receive cans of lesser height than that of a gallon can, the platform G is adjustable to different heights on the frame D as before mentioned. In order to support the platform G in elevated positions the guide ribs ii are each formed with a pair of superimposed spaced notches s and t and the platform G is fitted with a pair of complementary spring pressed catches 26 presented toward the ribs i-i for engagement with either of the notches s or t and thereby releasably hold the platform in its raised positions. One of the latches 26 is detailed in Fig. 9 as comprising a tubular housing u which is formed in continuation of the adjacent slideway h or h and has an open end presented to the rib i or i.
A bolt v slidable in the housing u is fitted with a stem w which projects from the inner end of the housing. A spring x wound on the stem bears against the bolt to normally hold it in an advanced position for engagement with the notches s-t. A laterally projecting handle y is mounted on the stem w whereby the bolt may be manually retracted to free it from engagement with the notch with which it is engaged.
In the operation of the invention a capped can I containing the material to be mixed, such as paint, is clamped between the platform G and the disk H by initially seating it on the platform beneath the then raised disk and then clamping the disk against the upper end of the can by manipulation of the stem 24. The can will then be securely held against displacement and the cap or lid thereof if unsecured to the can body tightly held in place.
To effect a mixing action on the contents of the can I the eccentric crank g is set in motion thereby rectilineally reciprocating and laterally oscillating the crank arm E which by reason of the pivotal mounting of the frame D on the pivots a--a' causes the frame D to swing forward and back in a rectilineal path of travel a single reciprocation on each revolution of the crank g as indicated by the full and dotted lines in Fig. 11 and denoted by the double headed arrow M. At the same time the frame D is caused to oscillate horizontally by virtue of the pivotal mounting of the yoke C carrying the frame D afforded by the pivot 14. The relative reciprocal and oscillatory movements of the frame D and the can I carried thereon is diagramed in Fig. and indicated by double headed arrows N and 0 respectively.
The solid lines here indicate diagrammatically the forwardmost position of the can I, frame D, crank arm members b-b and eccentric crank g, dot and dash lines indicate their intermediate positions, while the dotted lines indicate their retracted positions.
By the employment of the diverging crank arm members bb leading from the crank g to opposite sides of the frame D the latter will be caused to oscillate horizontally on rotation of the crank g, since, when the crank g is in its forwardmost position on a plane extending through the shaft 19 and pivot 14 the frame D will be disposed perpendicular to such plane, as indicated by the full lines in Fig. 10, then when the crank g is moved ninety degrees from its forwardmost position, the frame will be swung laterally on the pivot 14 to an angular position relative to its initial position as indicated by the broken lines D and D in Fig. 10. This oscillating movement of the frame D is of course imparted to the can I and its fluid contents thereby effecting a horizontal oscillating surging movement of the cans contents crosswise of back and forth surging movement effected by rocking of the container.
It is to be noted that by pivoting the frame D below its horizontal center and supporting the can on the platform G either on the lower end of the frame or either of the notches s-t, the major portion of the can will extend above the pivoted mounting of the frame and will therefore be caused to travel a greater distance than the lower portion thereof on the rectilineal rocking movement of the can. This movement is highly effective in agitating the contents of the can particularly where the can is mounted in an inverted position on the platform G with previously settled solids therein now located in the upper portion of the can.
The recited movements of the can elfect rapid and thorough mixing of its contents without appreciable jar and without disturbing noise as is generally occasioned by powered mixing machines.
While a specific embodiment of the invention has been shown and described, the invention is not limited to the exact details of construction set forth, and the invention embraces such changes, modifications and equivalents of the parts and their formation and arrangement as come within the purview of the appended claims.
