to the shell 2U as by the screws 26. The magnet 'I coil or solenoid 21 is mounted within the pole piece 25 and the cross member 28 is `attachedto the ends of the yoke or pole piece 25.
The adjusting screw 29 is threaded through the top of the yoke or pole piece 25 anda lock nut 30 is provided thereon for holding thescrew in adjusted position. This adjusting screw is internally threaded to receive the screw 24 which holds the cover 22 upon the shell.
The magnet coil 21 has a central longitudinal opening 3| within which the reciprocating armature 32 isl mounted for sliding movement.
This armature has the reduced extension 33 slidably located through the'aperture 34 in the cross piece 28, and an adjusting nut 35 and lock nut 36 are mounted thereon at a point spaced from the cross member, a compression spring 31 being located around the reduced extension 33 of the armature, between the cross member 28 and the nut 35 so as to normally urge the armature outward against the pull of the magnet.
A further reduced, threaded extension 38 may be formed upon the end of the reduced extension 33 for receiving the rounded locking nut 39 by `means of which the blade 4u is operatively connected to the armature.
A brass pilot pin 4| is centrally located upon the other end of the armature 32 and arranged to slide within the central opening 42 in the adjusting screw 29. l
The open end of the conical extremity 2| of the shell terminates in the inturned flange 43 against the inner side of which is located the enlarged head of the threaded binding stud 44, the binding plate 45 being clamped against the other side of said flange by means of the lock nut 46. l
The handle 41 may be formed of plastic or other suitable material and is provided with the angular portion 4B attached to the conical extremity 2| of the shell in any usual and well known manner, and preferably is located substantially parallel to the shell and spaced therefrom a sufficient distance to permit the handle to be grasped in one hand.
The binding plate 45 may be attached to the angular extension 48 of the handle as by the attaching screw 49, and the upper end of the liex- 56 from said cord lead through the thumb switch 51 to the magnet so that the operator may manually control the vibration of the blade.
Although only a single blade is shown in the drawing two or more blades may be provided if desired. The change of the thickness, width and length of the blade will change the active motion to diierent stages of beating or mixing. The blade should be only a few thousandths of yan inch thick at its lower end so that it is suii- Aciently exible to produce the desired whipping "action within the liquid. The arrows in Fig. l
indicate the general direction of movement of :theliquid produced by the vibration of the blade.
In Figs. 4 and 5 is shown an attachment which may be placed upon the blade if desired, This attachment, indicated generally at 58, may be formed of a strip of sheet metal or the like bent upon itself into substantially U-shape, forming the spaced parallel legs '59 preferably perforated at their lower ends as at 50, and terminating at their upper ends in the opposed notched extremiities 5| provided with the notches 62 to receive the threaded extension 38 and rounded nut 39 when the attachment is slipped over the tapered portion 63 of the blade 40. InFig. 6 is shown a slightly modified form of electromagnet which includes the U-shape pole piece or yoke 25a formed of soft iron or the like. The magnet coil or solenoid 21a is mounted withlin the pole piece and the cross member 28a is located across the ends of the legs of the U-shape yoke 25a.
The adjusting screw 29a, is threaded through the top of the pole piece 25a and a lock nut 30a is provided thereon for holding the screw in adible blade 40 may be attached to the handle as by the fastening screw 50, a spring washer 5| vbeing preferably located between the head of said screw and the upper portion of the blade while a half-round crown bearing 52 is located between the binding plate 45 and the blade, being received in the rounded socket 53 formed in the back side of the blade. The blade is tapered in thickness toward its lower end as best shown in Fig. 1 so that it will be flexible and produces Y a whipping action within the liquid to be mixed.
:Alongitudinal bore Y54 may be formed through )the handle 41, to accommodate the nexibie e1ec- Vtric cord 55 which may VV`be connected to a base "receptacle or other -source of current. The wires justed position. The reciprocating armature 32a is mounted for vertical sliding movement within lthe central longitudinal opening 3|a of the magnet coil 21a.
The armature is provided with the reduced extension 33a slidably located through the aperture 34a in the cross member 28a. and provided with the threaded portion 33h upon which is mounted the nut 33e for contact with the cross piece 28a, and spaced therefrom the nut 35a having a head 35h between which and the cross member is located a compression spring 31a. A lock nut 36a is located upon the threaded portion 33D of the extension adjacent to the nut 35a.
In Fig. 7 is illustrated a form of the device in which a flexible vibrating disc is provided for mixing the liquid 'or the like.
In this form of the invention the substantially cylindrical container |5a, for the liquid or the like to be mixed, may be formed of glass, metal or other suitable material and provided with a base 53 of rubber or the like. The cover or lid ISa, formed of sheet metal or the like, may be provided with the annular flange Ila fitting over the rim of the container and detachably connected thereto by the bayonet lock lb.
The electrical unit for producting the vibratory motion may be the same electromagnet illustrated in Fig. 1 and described above in detail. However, instead of being provided with a handle, as shown in Fig. l, the shell 20 of the magnet is mounted upon the cover |6a of the container, and the cover 22a of the shell is provided with a grommet 64 through which is located the electric cord 55a leading to the magnet.
The inturned flange .43 at the lower end of the conical portion 2| of the magnet shell is clamped against the top of the container cover |6a by means of the hollow screw stud 44a which is andere i screwed `into 'the enlarged, .internally "threaded upper .portionY 65 o'f'the depending tubular -.c1 umniiwhich extend'stofa .point near'the bottom 'of 'the Vcontainer |5a.
With this .construction and-1arrangement `of the :parts r the Vmagnet and vibrating :mixing tool are assembledas a unit upon the lcontainer cover Mia, so las to be attached toV or removed 'from the container by merelyplacing the :cover thereon or `removing ittherefrom. 1
TheV reduced extensionliSSa .ofthe armature of them-eignet is of 'considerable length, extending down through the tubular column 66 to a point below the end'of the same; .The lower end of the ,extension 33a is bored and tapped as indicated at 6l, to receive the screw 68 by means of which the vibratory,.mixing. disc 69 is `attached to the lower end of the '"extension.
This disc may be formed of sheet metal or Lthe 'like andfis 44only a-few thousaridths of fan inch '.thickfso that it .is .quite Y flexible .fand may vibrate vastindicated in .broken .lines inFig. 7 "Whenthe Amagnetisenergized. .Aperturesl are preferably provided in the. disc-09,. andthe size and arrangement of aperturesmaybe varied as desired, Vor the apertures .may be Veliminatedrentirely.
A stationary, rigid .disc 7| I 'is 'mounted upon the lower portion ofthetubularcolunm 66, by means ofthe set 'screw l2.. located .through the lhub 113 .of
' With-thisconstruction the .disc 1| may be adjusted upon the column 65 relative to the vibratory disc 69. Apertures 14 may, if desired, be formed in the disc 1|, and the size and arrangement of these apertures is also optional.
When the device is assembled as shown irl-Fig. 7 and the magnet energized the flexible disc 69 will be rapidly vibrated, setting up a motion in the liquid as indicated by the arrows in said iigure, quickly and uniformly mixing and blending the contents of the container.
A portable adaptation of the mixer shown in Fig. '7, for use with any bowl or container, is illustrated in Fig. 10 in which the magnet shell 20 has a handle l5 connected thereto substantially at a right angle to the axis of the shell and the electric cord 55h is located through said handle and connected to the magnet and to the switch 5l?) in usual and well known manner.
The tubular `column 66 and elongated reduced extension 33a of the armature may be the same as illustrated and described in detail in Fig. 7 and are provided respectively with the stationary disc 'il and the vibrating disc 69 of the same construction as illustrated in Fig. '7. In using this type of mixer the handle 'l5 is grasped in the hand and the discs are submerged in the liquid to be mixed, which may be placed in any bowl or other suitable container and when the switch 51h is operated to energize the magnet the action of the mixer will be the same as illustrated and described in Fig. 7.
A deluxe form of the invention is illustrated in Fig. 12 in which the liquid container may be in the for-rn of a glass bowl or pitcher |5b provided with a handle 16 by means of which the device may be transported from place to place or tilted to pour the contents from the container.
The glass container |5b is mounted upon a base or shell 'll formed of metal or the like and provides a housing for the electromagnet. This magnet includes the soft iron yoke 25h within which is mounted the magnet coil 2lb, the cross piece 25h being connected to the ends of the yoke. The adjusting screw 29h is located through the lower end of the yoke and locked by means of the devicewill operate noiselessly.
plug-in points, Athrough the switch 8| @to :the
magnet. Feet 82, of *rubber or the ilike, may `'be provided upon the bottom plate "l 'so that 'fthe The glass container I5b is pivotally connected tothe base or shell Tl by means v.o'ffthe'ilangeSl Y and threaded stud portion T84' of the tubular column 85. A'gasket '8'6 of rubber or the like is lo- "c'ated -between theilan'ge 83 and the bottom wall foftheigla'sscontainer and the' threaded stud por- -tionf84- of 'the column received --in the threaded laperture-"Sl of the binding plate 83. A pair of spacing standards 89 are connected -to the ycross member 28h of the magnet and the reduced-ends 90 thereof are received in the apertures 9| formed in the binding plate, thus assemblinglthe container shell and magnet together as a unit.
`The reduced threaded stud 385of the magnet armature, is received in the threaded socket l02 of the vibrating rod '93 which extends upward through the ltubular column 85 to a distance spaced above the top thereof.
' The sleeve 94 surrounds the tubular column-85 and is connected at its upper endto -the upper end of the vibrating rod 93 as by the screw 95.
A thin flexible disc S6 is carried by the lower end of the sleeve 94 and if desired may be provided with apertures 91.
yIn the operation of the device the liquid to be mixed is placed in the container |5b and the switch 8| is operated to energize the magnet causing the rod 93, and through it the sleeve 94, carrying the disc 96, to be rapidly vibrated vibrating the disc within the liquid and producing a motion of the liquid as indicated by the arrows in Figure 12.
In Fig. 11 is shown another means for producing a rapid reciprocation of the discs. In this device a motor is indicated at |00 and a cam |0| is xed upon the shaft |02 thereof, a, tube |03 with a rod |04 slidable therein are provided for carrying a pair of discs such as shown in the other forms of the invention. A coil spring |05 is located around the rod |04 between the end of the tubeand the shoulder |00 on the rod, holding the rod against the cam so that as the cam is rotated it causes a rapid reciprocation of the rod.
A slight modification of the mixer shown in Fig. '7 is indicated in Fig. 14 in which the glass or container |01 is provided with a 4lid or cover |08 having a tubular extension |09 through which the tube ||0 is located. This tube is connected at its upper end to the housing `which contains the electro-magnet, and a knob ||2 is provided upon the top of the housing for manipulating the same.
The disc H3 is xed to the lower end of the tube |I0 and the rod ||4 is slidably located through the tube and connected at its upper end to the armature of the electro-magnet and has the disc ||5 connected to its lower end. y
In operation, the knob` ||2 is grasped in the hand and raised and lowered, moving the disc I3-I |5 between the full line position and broken lineV position shown in Fig. 14, thus making a thorough mix in a very short time.
The mixers herein illustrated and above described produce a very violent action in mixing or beating the liquids and in breaking up or dissolving solids such as malted milk powder and the like and with the use of these mixers it is possible to emulsify oil and Water in a few seconds.
Due to the fact that malted milk powder does not readily mix with milk or other liquid it is common practice to mix the powder with a small quantity of milk until it assumes a pasty form after whichA the full quantity of milk or other liquid is added and mixed.
In using either the disc or blade type of mixers to which the present invention pertains it is only necessary tok place the desired quantity of milk or other liquid in the container and put the powdered malt on top of the liquid and after the magnet is energized the powdered malt is whipped through the liquid to a creamy consistency in from ve to ten seconds.
