DRINK MIXER.

. Application filed February 25, 1922. Serial No. 539,059.

T 0 all whom it'wwy concern:

Be it known that l', RAYMOND B. GIL- CHRIST, a citizen of the United States, and a resident 'of Newark, in-the county, of Essex and State of N cw Jersey, have invented certain new and useful Improvements in Drink Mixers, of which the following is a full, clear, and exact description.

The invention relates to drink mixers.

In machines for this purpose, the liquid constituents of the drink to be mixed are usually poured into a receptacle which is generally designated a shaker, from many different containers disposed away from the mixer. The receptacle with these constituents therein is brought to the mixer and placed in operative relation thereto and .is removed from the machine after each mixing operation, to discharge its contents. This is rendered necessary, because so many different ingredients and flavors are used in making drinks that they are, in nearly all cases, mixed individually. It is usually n'ec essary to run the agitator for a considerable period to properly blend or mix the constituents and,,therefore, it is desirable that provision be made for retainin the receptacle and agitator in operative re ation to permit the dispenser to perform other duties during the mixing operation. In drink-mix ing, it thus becomes necessary to frequently place the receptacle containing the constituents into cooperatiue'relation to the agitator and to withdraw it from the machine to dis charge its contents and cleanse the recepthe receptacle in cooperative relation to the agitator, it has been necessary in their use to manually manipulate the receptacle ntoh operative position and withdraw it there;

from and to additionally perform some sep-- arate step or operation, such. as lowering the motor and agitator together, or shifting the agitator and its shaft into the receptacle and relativelyto the motor, or raising and locking a receptacle-support to estabthe receptacle and agitator or to control the operation of the machine. Another desideratum in this art is to simplify the machine; by dispensing with movable connections in and for the driving mechanism for the agitator. I

One object is to provide an improved motor-driven drink-mixer having an agitator which is mounted to work or rotate at a substantially fixed point with respect to the motor, with means adapted to receive the receptacle and automatically retain the agita-tor and receptacle in cooperative relation as a result of the manual manipulation or placement of the receptacle itself.

Another object is to provide a mixer of this character with automatic means for controlling the motor responsively to placement and removal of the receptacle.

A further. object of the invention is to provide improved means for removably holding a receptacle in cooperative relation with the agitator on a shaft depending from a stationarily supported electric motor.

A still further object is to provide improved means for controlling the operation of the motor which drives the agitator.

Another object of the invention is to provide a machine which is simple in construction, which may be easily and readily operated and which is efficient in operation.

Other objects of the-invention will more fully appear from the following description.

The invention consists in the several novel features hereinafter set forth and more particularly, defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a side elevation of machine embodying theinvention. Fig. 2 is a front elevation of the receptacle guide. Fig. 3 is a vertical section. Fig. 4 is a section on line 4-4. of Fig. 3. Fig. 5 is a sect'ion on'line 5-5 of Fig. 3. Fig. 6 is a sec tion on line 6-6 of Fig. 3.

The invention is exemplified in a machine comprising an electric motor 10 f usual construction, to the rotor of which is secured ".a pendant shaft 11 with an agitator 12 fixed to its lower end; a hollow supporting standard omprising a lower portion 13 fixed to a bottom member 14 whlch is secured to a base 15 by a screw 16, an upper member 17 suitably secured in the member 13, and a lish and, maintain cooperative relation of bracket 18 suitably secured to the upper end.

' of member 17 to which the motor is suit 23,connected to the motor and, normally. disconnected switch-members 24 and 25 included in the conductor 23 to control the operation of the motor. The casing of the motor 10 is fixedly secured to the support at 19 and the agitator 12 is maintained in substantially relatively fixed vertical relation to the motor.

A receptacle 26 having an open top, a closed bottom 27, a lower wear-band 28 and an upper wear-band 29, is adapted to .contain the constituents of the drink tobe mixed and to be placed into cooperative relation to the agitator from beneath the latter, which is supported sufliciently above the base 15 and away from the receptacle-support hereinafter set forth to permit the insertion and withdrawal of the receptacle. I

The invention contemplates placement of the receptacle into and out of operative relation to the agitator, locking and unlocking the receptacle and control of the motor by manipulation of the receptacle itself, so that shift of the motor or the agitator are not necessary to bring the agitator into working position in the receptacle. For this purpose, a stationary vertically extending receptacle-guide is provided for the back of the receptacle and comprises a lower inclined or upwardly and backwardly sloping member or portion 30 and a vertical upper portion 31 with a supporting-ledge 32 between'them. The guide has its front face curved or arcuate in substantial conformity with the outer periphery of the receptacle so that when the latter is pressed backwardly against the guide, the receptacle will be guided against lateral movement and into its operative position without danger of striking the agitator 12.

he receptacle is adapted to be removably' and securely held in operative position by the ledge 32 which has an inclined rearward- 13' and downwardly extgiding surface 32 to efiect the lower portion ofthe receptacle backwardly against the front face of the guide-member 31 and hook 33 which is adapted, in conjunction with said member, to hold the upper portion of the receptacle against lateral movement in any direction,

being extended into the receptacle to engage its inner-periphery for this purpose.

y causing the abutment or holding member 33 to confine the upper and rear portion of the receptacle, the weight f the front portion of the receptacle and the material therein will tend to hold the lower portion of the receptacle in its seat on ledge 32 and against guide-member 31. Hook 33 is secured by screws 33 to a strip 13' and guide 31 is provided with lugs31 which are also secured to strip 13*. The latter is secured to the supporting standard by screws 13*.

For the purpose of automatically controlling the operation of the motor bymanipulation of the receptacle, a switch-lever 34 has its lower end 35 formed to pivotally fit in the lower end of the standard-member 13 and on the plate 14, is extended through a slot 36 in front of thesupporting-standard and through a slot 37 formed in guidemember 31 and is provided with a camportion 38 which is adapted to be struck by the receptacle 26 while it is being raised into operative position and to beheld in shifted position as long as the receptacle remains in its operative position. A stop-shoulder 34 is provided on lever 34 to limit the forward movement of the lever under the influence of spring 43, so it will be normally projected into the path of the receptacle the correct distance to operate the motorswitch. Lever 34 is also formed with a cam 39 in the hollow standard, to shift and control a plunger .40 which is slidably held in the hollow-standard and carries a switchpin 41 at its upper end which is adapted to bridge the gap between the normally separated switch-members 24 and 25 and close insulating material 44 suitably held in the upper end of the standard-member 17. "A wear-plate 45 is secured to the lower end of plunger 40. y

The operation of the machine will be as follows: Assuming the parts to be in normal position shown in Fig. 1, the operator will place receptacle 26 containing the constituents of the drink to be mixed, against inclined guide-member 30 and under the agitator 12 as shown by dotted lines in Fig. 1, press it rearwardly with sufficient force to cause the guide to laterally control its vertical movement, and then lift it. In this manipulation, the receptacle will slide on the front-face of the receptacle-guide.

After the receptacle leaves the inclined guide-member 30, it will bear against the vertical guide-member 31 and be raised until that the cam 39 will raisethe plunger 40,

cause the pin-41 to bridge the switch-members 24, 25 and close the circuit for the operation of the motor 10 and cause it to drive the agitator. This occurs preferably before the receptacle reachesits operative position so that the agitator willbe rotating and bore its way through any hard material, such as ice cream, as the receptacle is being lifted. The hook or holder 33 positively holds the upper portion of the receptacle, so that it will not be displaced by the forward pressure of the switch lever 34 which isunderjhe influence of spring 43 which tends to hold the switch-lever normally in the position shown in Fig. .2 and to hold the receptacle. When the motor has run for the desired period and the mixing operation has been completed, the operator will raise the receptacle 26 sufliciently to cause it to clear the inclined surface 32 of ledge 32 and tilt the lower portion of the.

receptacle forwardly a short distance to cause its lower back portion to clear, and be released from, the ledge. Thereafter, the operator will lower the receptacle and press it backwardly sufficiently so that the receptacle will follow the path controlled by guide-members 31 and 32. The wear-band 29 is of sufficient height to prevent its lower edge from catching on ledge 32 while the receptacle is being lowered. When the receptacle has been lowered sufliciently to clear the agitator 12, it will be withdrawn forwardly away from guide-member 30. During the lowering of the receptacle, the switch-lever 34 will pass into its normal position to release plunger 40 and cause it to break the circuit and stop the motor. This occurs, preferably, after the vessel has been lowered sufficiently to bring the liquid therein below the agitator so the latter will'run for a suflicient period to discharge the adherent liquid by centrifugal force into the receptacle.

In the drink-mixers comprising an electric-motor with an agitator attached to its rotor, a high speed, usually ranging from 5,000 to 14.000 revolutions per minute, is attained, and when a receptacle or container which issubstantially circular in cross-section,'as illustrated in the drawings, is used, the agitator. if operating concentrlcally 1n the receptacle, will rotate the entire contents or liquid in the receptacle at a high speed and produce a vortex in the material. By retarding the rotation of the contents to cause greater relative rotation of the agitator and latter will pass into or nearly into concentric relation to the receptacle and then produce or increase the vortex. This is of advantage, because during the withdrawal of the receptacle, the vortex will cause the liquid to clear the agitator sufliciently early to cause the agitator to centrifugally cleanse itself by discharging the adherent particles into the receptacle before the latter is completely withdrawn.

The axis of the receptacle while it is in its operative position, is disposed between the agitator and the supporting column. A characteristic advantage of this arrangement is that it provides additional clearance for the receptacle in itsplacement into and its removal from its operative position.

The invention exemplifies a motor-driven drink-mixer with an agitator carried in substantially fixed relation to the motor; in which manual manipulation of the receptacle itself, results in bringing it and the agitator into and in automatically retaining them, in cooperativerelation; in which manual ma nipulation of the receptacle itself results in automatically retaining it and the agitator in cooperative relation and in automatically controlling the motor; in which the receptacle-holding -means and the agitator are normally and co-relatively positioned with clearance to permit the receptacle to be readily placed into and withdrawn from its operative position; in'which placement and securing of .the receptacle in its holding-means are accomplished by manually shifting the receptacle itself backwardly and upwardly around the agitator to its point of deposit, in which the motor and agitator are statio11- arily mounted and the receptacle-holding means is disposed entirely at the rear of the agitator'to provide receptacle-clearance between the support and the agitator; in which a substantially stationary receptacle-support is used with a stationarily mounted agitator; in which the switch for the motor is receptacle-controlled and closed in advance ofthe time when the receptacle passes into its fixed operative position; in which said switch is opened after the receptacle has been partly lowered from its fixed position; in which the receptacle is well guided in its placement 1 and removal; in which the agitator operates eccentrically while the receptacle is'retained and concentrically during its withdrawal; in which the receptacle holding means is simple in construction; and by which the steps to be performed by the dispenser are simpli fied and reduced to the minimum and the service expeditedand improved. I

It is to be understood that the novel features may be separately used without including the others, inacc0rdance with the appended claims. v
