' fountain or RICHARD H. STRINGHAM, OF BQUNTIFUL, UTAH.
ELECTRICAL DRINK-MIXER.
To all whom t may concern.'
Be it known that I, RICHARD dum-I STRINGHAM, a citizen of the United States,
residing at Bountiful, in the county of Davis and State of Utah, have invented certain new and useful Improvements in Electrical Drink-Mixers, of which the following is a specification.
1 My invention relates to new and useful improvements in drink mixers for soda bar use for mixing malted milks, egg-nogs2 frapps and the like,and .has for one object, the construction of an electric mixer which has no fine wires to burn outl or brushes to replace, employing no commutatdr," slip rings, sliding contacts, or flexible connections, and therefore being economical in manufactureV and durable and eflicient in use.
A further object of `my invention consists in constructing an electric drink mixer in which a motor of the squirrel-cage type is employed and in which the rotor in 1tself forms the mixing element.l
Another object of my invention isvto provide a motor of the character mentioned which will operate at higher speeds than the motors now commonly employed in electric drink mixers and which as a result will cause a more rapid and perfect mixing of drinks.
Electric mixers as now commonly employed although superior to manual mixing devices are objectionable in that the motor is usually more or less noisy. A further object of this invention consists in constructing a motor which will be quiet in operation, this being accomplished largely byemploying the rotor of the motor as the mixing element so that it is immersed in the liquid being mixed which will, therefore, act as a cushioning agent and partially by mounting the casing of the device upon cushioning or shock absorbing supports.
A still further object which I have in view is the provision of means for preventing loss of liquid beingmixed through overflowing from the mixingl container or splashing therefrom.
And a still further object of my invention is the construction of a mixer which will be more Compact and nearer and more Specification of Letters Patent.

pleasing in appearance than those formerly in use. n
Vith these and other objects 1n view, my
`:invention will be more fullv described, illustrated in the accompanying drawings and then specificallyv pointed out in the claims which are attached to and form a part of this application.
In the drawings:
Figure 1 is a central vertical sectional. view cf my improved mixer;
Fia. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1 looking in the direction of the arrows;
Fig. 3 is a fragmentary perspective view of the rotor supporting member and mixing glass:
Fim 4 is a side elevation .of a switch employed for controlling the motor;

F ig. 6 is a diagrammatic view of the wiring of the device;
Fig. 7 is a perspective view of the mixer clearly illustrating its compact and neat appearance.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
My improved electric mixer includes a substantially rectangular metallic, neatly finished casing or housing 10 which forms a support for a mixing glass 11 and which incloses the stator 12 of the electric motor 13. This casing has cushioning plugs 14 of rubber or equivalent material insertedin its base lwhich serve to absorb shocks or jars and render the device quiet and which also serve to prevent slipping of the device upon a polished table or shelf. y
The form of rotor employed isa single phase alternating current motor of the squirrel-cage type and includes the stator 12 which is built up of laminated iron, the stator rings being clamped between nuts 15 threaded upon bolts 16 passed through the top wall of the casing and anchored by nuts 17. This stator core or element carries the usual two pole two phase winding 18. Co-
operating with this stator is a rotor 19 built up of laminated iron in the form of a disk having a central opening in which is shrunk a bushing or bearing 2O and the squirrelcage conductors 21 are fixed about its rim. The laniinations making up this rotor are also provided with a series of openings 22 alining with each other to form openings completely through the rotor and preferably conccntrically disposed therein.
The upper wall of the casing is formed directly above the stator of the motor with an opening 23 through which the base of the mixing glass 11 may pass so that the lower portion of the glass will be disposed within the casing and between the poles of the stator, as clearly shown in Fig. 1. A supporting or armature shaft 24 is provided at one end with a head 25 having a squared socket 26 to engageabout a squared plug or boss 27 formed uponthe inner side of the bottom of the mixing glass and centrally thereof. This shaft is adapted to revolubly support the rotor 19 within the glass and in spaced relation to the bottom thereof but is itself held against turning through its locking connection with the glass. A vane of sheet metal or equivalent material 28 is proportioned to lit in the upper part of the mixing glass and has its side edges angularly disposed to conform to the taper of the glass. This vane centrally of its width is formed with transverse incisions 29 in order that portions at opposite sides of the incisions may be oppositely outbent -to provide half sleeves 30 sothat the vane may be slipped over the upper end of the shaft 24 and serve as a centering means for the shaft. This vane also prevents any loss of liquid being mixed through spattering or overflow as will be later pointed out. As the rotor forms th'e mixing element and is immersed in the liquid being mixed, it is referably covered with a thin coating of suitable material such as Celluloid or collodion so that it may be conveniently cleaned by immersion in Water and so that all crevices which might collect foreign matter will be closed.
Screws 31 secured in opposite end walls of the easing by nuts 32, support in one instancea tube 33 of porcelain, fiber, or other non-conducting material and in the other instance a core, 34 of an inductive resistance coil 35 having the winding 36. A non-inductive resistance winding 37 is carried by the tube,33. The purpose of these windings will be later pointed out in detail. Mounted withinV the housing 10 and supported by a base 38 of insulating material is a switch 39. This switch includes a bracket 40 which pivotally supports a knifeblade 41 movable into engagement with the knife blade contacts 42 of the switch which are in electrical connection with a binding post 43, a binding post 44 carried by the 65- bracket constituting the other terminal of the switch. A spring 45 fixed to the knife blade and to a stud 47 carried by the base normally serves to hold the switch in open position, its movement being limited by a 76 stop shoulder 48 formed on the bracket. AThis switch is so disposed that in open position the Contact engaging end of the knife blade member of the switch projects so that the positioning of the mixing glass, as shown in Fig. 1, will engage it to swing it and close the switch. Obviously when the glass is removed the spring 45 will immediately swing the switch blade to open the switch.
The stator windings at one terminal are in 30 electrical connection 49 with one of the binding posts of the switch and their opposite terminals are in electrical connections 50 and 51 with the non-inductive resistance coil 37 and iinductive resistance winding 36, respectively. One line wire 52 is electrically connected to both resistance .coils and the other line wire 53 is connected to the othcil binding post of the switch. This wiring is clearly shown in Fig. 6. It will. therefore, 99 be seen that one set of coils is in series with the non-inductive resistance and the other in series with the inductive resistance or reactance and that both of these coils are in parallel with the line wire with the result that the current in one coil will lag behind that of another coil and will give rise to a rotating magnetic field.
In operation the rotor is mounted upon the shaft 24 and both the rotor and shaft are inserted in the mixing glass 11, the shaft being turned until it locks with the glass. The vane 28 is then applied to the upper end of the shaft and moved into engagement with the glass to center the shaft and the 195 various ingredients-to be mixed are put in the glass. The mixing glass is then positioned in the casing, as shown in Fig. 1, thereby closing the switch and energizing the motor to cause rotation of the rotor and consequent mixing of the various ingredients contained in the glass. The rapid turning of the rotor, of course, causes the liquids contained in the glass to turn and, consequently, climb the sides of the glass but the vane extending diametrically across the upper end of the glass, breaks up the rotating current and prevents overflow from the glass or spattering.
After the drink has been properly mixed the glass is removed from the casing which automatically opens the switch. The shaft 24, together with its vane and rotor, are lifted from the glass and the contents of the glass is emptied into one or more service glasses. Both the mixing glass and the parts of the mixer for operating therewith. namely, the rotor, rotor shaft and vane, may
be readily Washed and cleansed through immersion in either cold or hot water as preferred when the device is again ready for use.
The motor is adapted to operate on a single phase alternating current of 110 to 120 volts and therefore may be driven by the usual lighting current. The operation of the motor is accomplished through splitting I the rotor squirrel-cage conductors inducing currents in them which tend to drag the rotor around with .the field. As it increases .in speed ,the torque on the rotor becomes greater and greater until its rated speed is approached. lVith .a motor having a two pole winding of this character the rotative speed of the rotor would be the same as the frequency of the alterations of the exciting current if there were nolosses but some loss occurs, due to the space .between the rotor and stator core. However, an extremely high rotor speed is obtained and the loss is immaterial considering the rapidity with which the mixing is Iaccomplished and the short periods during which the device is used. All current conducting parts are', of course, suitably insulated from the casing.
Although I have illustrated my invention in detail and described its specific structure, it will, of course, be understood that I reserve the right to make any changes or alterations within the scope of the claims.
