To all 'whom it may concern.'
Be it known that I, WILLIAM GENTRY SHELTON, a citizen of the United States of America, residing in the borou h of Manhattan, city, county, and State o New York, havey invented certan new and useful Improvements in Drink-Mixers, of which the following is a specification.
This invention relates' to stirrers, commonly designated drink-mixers, and aims to rovidel improvements therein. p
he invention provides a drink-mixer which is of simple and durable construction, well adapted t0 give goodservice under. the more or less rou h and ready usage which such devices unerg'o in the hands of a'ttendants at soda fountains, bars, etc.
The invention further provides a device wherein the mixing may be thoroughly and more quickly done than by the use of drinkmixers heretofore commonly in use.
The invention further provides novel features lof combination, and sub-combination, hereinafter more fully described, for effecting, in an improved manner, the functions of a drink-mixer. f
An embodiment of the invention is illustrated in the accompanying drawing, wherein:
Figure 1 is an elevation (partly in section) of said embodiment.
Fig. 2 is a to plan view of the construction shown in ig. 1.
Fig. 3 'is a diagrammatical view, illustrating the movement of the stirrer, during mixteferring t0 said drawings, numeral 1 designates a stirrer of any suitable type, usually long and slender, so as to project into a glass, and with a knob 2 at its lower end, as shown. The stirrer is driven by suitable means 3, and preferably at high speed, preferably by an electric motor, on the rotor of which the stirrer is preferably directly mounted and driven.
5 designates the suspension for the stirrer.-
The suspension is such as to permit some` yielding of the stirrer ofi' of its axis, whereby shocks and vibrations of the stirrer in rotation are absorbed in the suspension, thereby relieving the bearings of the stirrer and associated part, and whereby the stirrer, in whole or in part, during rotation, moves mixin of the substances to be mixed.
axis o the stirrer, in its orbit, may generate a cylinder or a cone (see Fig. 3 and the dotted lines Fig. 1).
When the stirrer is mounted directly on the rotor of an'electric motor,as is preferably the case, the suspension of the stirrer is preferably through the motor casing.
The suspension 5 may conveniently com- 1prise a pillar or standard v7, having an overanging arm 8, preferably with four rightangle branches 9, 10, 11, 12, and, between the four branches and the motor casing, (or other part carrying the stirrer) there are arranged four flexible links or connections 15, 16, 17, 18, which maybe in the form of coiled springs. Stiff coiled springs have been found to give good results.
A suspension having more links than two, such as a four-point suspension, has been found to have an advantage, as the movement, especially the revolution of 'the stirrer,
is found to take place steadily, and also is found to admit of a movement of the stirrer, whereby the axis thereof generates a cylinder. Any other form of suspension, how` ever, admittin of a steady revolution,.dur ing rotation o the stirrer, or its mixing end, could be used instead of that just described.
Conveniently, the pillar or standard 7 is made of two telescoping tubular parts, 20, 21, extensible to withdraw the stirrer from a glass and collapsible to bring the stiri'er into a glass. The two telescoping parts 20, 21, are conveniently normally pressed to eX- tended position by means of a coil-spring 23, guided on a rod 24 within the said tubular parts, and a latch or catch 25 is conveniently provided fo-r holding the parts 20, 21, in collapsed position, with the stirrer lowered in position for mixing.
Means 30 are also preferably provided for automatically Hmaking an electric circuit to energize the motor when the telescoping parts 20, 21 are collapsed. This means 30 conveniently comprises a conducting piece 32, connected, by an insulating nipple or part 33, to an end of the rod 24. One of the telescoping'parts 20, 21-the part 21 in the embodiment shown-carries two terminals -35, 36, co`nne`cted to the'ends cfa break in a leading wire connected to the motor, and the circuit to the motor is adapted to be conpleted between the two l terminals 35, 36 through the conductlng-piece 32.
. Operation., When the stirrer 1 is rotated in a-liquid,
or a liquid and solid, or semi-solid, there is a, reaction which causesthe stirrer to vee'r olf of its axis, where the suspension is flexible, accordin to the present idea, and the cumulative e ect of these reactions 1s to cause the axis of the stirrer to revolve 1n a circle, so that its axis generates a cylinder or cone. The flexibility of the ysuspension admits of the motor or other art carrying the stirrer 'to' yield, and also a sorbs the vibratory forces and relieves the bearings ofthe stirrer or motor from excessive shock or strain. Therevolution of the stirrer, o r its free end, during rotation, causes the stlrrer to move around to dierent' parts of the materials to be mixed, and, hence, produces a mixing in a much shorter time than if the stirrer did not revolve.
Where. the device embodies the telescoping standard and the automatic electric switch, the stirrer is inserted in a glass, and the tion thereof simultaneously begun, by simply pressing on the top of the standard, the parts 20, 21 collapsing under the resistance o f the spring 23, andthe part 32,' on-the rod v 24, maklng contact between the terminals `35, 36, in the leading-sin wire to the motor. The
catch or latch 25 holds the parts in collapsed position during the stirring or mixing operation. To remove the glass and stop the motor, it is simply necessary to trip the catch theaxis of said rotary stirrer may revolve,
and thereby generate the surface of a cone or cylinder.
2. A drink-mixer, comprising an elongated stirrer, and a more-than-two-point suspensionfor said stirrer, ada tedlto yield in such V manner and degree un er the reactions to -the rotation of said stirrer l in a liquid mixture, and that the axis of said rotary stirrer may revolve, and therebygenerate the surv face of a cone or cylinder.
3. A drink-mixer, comprising an elon ted stirrer, and a more-than-two-pointl e astio suspension for said stirrer, adapted to yield in such manner and degree under the reac-v tions to rotation of sai stirrer in a liquid mixture, and that the axis stirrer ma revo1ve,and thereby generate the surface ofy a cone or cylinder. l
4. A drink-mixer, comprising an elongated of said rotary stirrer, and a four-point suspension for said stirrer, adzpted to degree un er the reactions to rotation of said stirrer in a liquid mixture, and that the axis of said rotary stirrer may revolve, and thereby generate the surface ofl a cone or cylinder.
5. A drink-mixer, comprising an elongated stirrer, and-a four-point elastic 'suspension yield in such manner and for said stirrer, adapted to yield in such comprising fmotor, an elongated stirrer mounted on? said motor, and a suspension for said motor, adapted to yield in such manner and degree under the reactions to rotation of said stirrer in a liquid mixture, that the wear and tear on the motor is lessened, and the axis of said rotary stirrer may revolve, erate the surface of a cone or cylinder.
8. A drink-mixer, comprising a motor, an elongated stirrer mounted on said motor, and a more-than-two-pointsuspension for said motor, adapted to yield in such manner and degree under the reactions to rotation of said stirrer, in a liquid mixture, that the wear and tear on the motor is lessened, and the axis of vsaid rotary stirrer may revolve, and therebygenerate the surface of a cone or cylinder.
9. A drink-mixer, comprising a motor, an elongated stirrer mountedy on said motor, and a four-point suspension for said motor, adapted to yield in such manner and degree under the' reactions to rotation of said stirrer in a liquid mixture, that the wear and tear on the motor is lessened, and the axis of ysaid rotary vstirrer may revolve, and
a liquid mixture, A
and thereby genthereby generate the surface of a cone or cylinder. y
10. A drink-mixer, comprising an electric motor, a support for said motor, and a switch, said support comprising telescopingv parts, a rod, and said switch comprising a pair of termlnals on one of said telescoping parts, and a conducting head on theend of said rod adapted to make "a circuit through said terminals in a determined position of said telescoping parts.
