:DRINK MIXER.

i f Application led 'March 8,- 1922. .Serial No. 541,911.

To all whom it may concern: Be it known-that I, RAYMOND B. GIL- oHRIsT, a citizen of the United States, and a resident of Newark, in the county of Es- 5 sex and State of New 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. ln 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 diierent containers disposed away from the mixer. rlhe 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. lt is usually necessary to run the agitator fora considerable period to properly blend or mix the constituents and, therefore,l itis desirable that provision be made for retaining the receptacle and agitator.- in operative relation to permit the dispenser to perform other duties during the mixing operation. in drinkmixing, it thus becomes necessary to frequently place the receptacle containing the constituents into cooperative relation to the agitator and/,to withdraw it from the machine to discharge its contents and cleanse the receptacle between mixing operations.

A desideratum in this art is to expedite and simplify the operations necessary to bring the receptacle and agitator into cooperative relation, to maintain them in such relation, in starting and stopping of the motor and thef removal" of the receptacle. Heretofore, in machines whereof I am' aware (excepting those exhibited in other concurr rently pending applications), it has been necessary in their use to 'manually manipulate the receptacle into operative position and withdraw it therefrom and to additionally perform some separate step. or opera- 0 tion, such as lowering the motor and agitator together, or shifting the agitator and its shaft into the receptacle and relatively to the motor,or raising and locking a receptacle-support to establish and maintain cooperative relation of the receptacle and agitator or to control the operation of the machlne. Another desideratum in this art is to slmpllfy the machine by dispensing with movable connections in and for the driving mechanism for the agitator.

One object of the present invention is to provide an improved drink mixer in which these additional operations or steps are ydispensed with and in which manual shift of the receptacle is utilized to completely control t he operation of the machine and t'o secure 1t and the agitator in cooperative relation. By dispensing with the necessity ,of these additional steps or operations, the time of the dispenser in performing them is saved and the service is improved.

Another object of `the invention is to provide a machine of this type vin which movf able connections in and for the driving melianism for the agitator/are dispensed W1v Another Object of the invention is to prov ide a machine which is simple in construction, which may be easily and readily operated and which is eiicient in operation.

Other objects of the invention`- will more fullyv appear fromhthe following Idescripion.

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

ln the drawings: Fig. 1 is a vertical section of a machine embodying the invention parts being shown in elevation. is a section on line 2-2^of Fig. 1l. Fig 3 is wa detaliof the hook-connection between the )receptacle and the guide. i

rllhe invention is exemplied in a machine comprising an electric motor l() of usual construction, to the rotor of which is secured a pendent shaft 11 with an agitator 12 fixed to its lower end; a hollow supporting stand.

ard comprising a lower portion 13 fixed to a bottom-member 14; which is secured to a base d5 by a -screw 16, and an upper member 17 suitably secured in the member 13; and a bracket 18 suitably secured to the upper end of member 17, to which the motor 10 is suitably secured, as at 19. The electrical connections for supplying energy to the mo- Fig. 2

tor 1() comprise a conductor-cord 20 leading through a handle 2l and comprising con- 24 and 25 being included in the conductor 23 to control the operation of the motoxr. The casing of the motor 10 is lixedly 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 and an upper downwardly extending flange 29, is adapted to contain the constituents of the drink to be mixed and to be placed into cooperative relation to" the agitator from beneath the latter, which` is supported sufficiently above the base115 to permit the insertion 4and .withdrawal of the receptacle. l

The invention contemplates placement of' the receptacle into andout of operative relation to the agitator, locking and unlocking the receptacle and control of Athe motor by manipulation of the receptacle itself, so that shift of the ymotor 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 3() and a vertical upper` portion 31, 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 int-o its operative position without danger of striking the agitator 12.

The receptacle is adapted to be removably secured in its operative position by the flange 2.9 which constitutes an annular hook adapted to extend around the arcuate upper end of the stationary guide member 31. A guard member 33, which is secured to standard member 17 by screws 33', extends over the upper rim of the receptacle and downwardly into it so as to form a stop for limiting the upward movement of the receptacle and also for limiting the forward movement of the upper portion of the receptacle, to

prevent it from striking the agitator. By

suspending the rear portion of the receptacle from the upper end of .the guide, the

Weight of the front portipn of the receptacle and the material therein will tend to hold the'receptacle against guide member 31. The

stationary receptacle guide is secured to the standard by lugs 32.

For the purpose of ling the operation of the motor by manipulation -of the receptacle, a switch-lever 34 has its lower end 35 formed to pivotallyit in the lower` end -`of the standard-member 13 and on the plate 14, is extended through a slot 36 in front of the supporting-standard andi tol cause the automatically control-l distance to operate the motor-switch. Lever.

34 is also formed vwith a cam 39 in the hol-k low standard, to shift and control a plunger 40 which is slidably held in the hollowstandard and carries'a switch-pin 41 at its upper end which is adapted tobridge the gap between the normally separated switch-member-S24 and 25 and close the circuit. for the operation of motor f10. Switch-members 24 and25-are secured to a block 42 of insulating material. Plunger 40 may7 be formed of insulating material, (such as wood, and is normally presseddownwardly by a spring 43 interposed between a shoulder on the plug and aplate of insulating material 44 suitably held in the upper end lof the standard-member 17. A' wear-plate 45 is secured to the lower end of plunger 40.

The operation of the machine will be as follows: Assuming the parts to be in ndrmal position shown in Fig. 1, theoperator will place receptacle 26,-containing the constituents of the drink to be mixed, against inclined guide-member 30 and under ,the agi- .tator 12, as shown by dotted linesfin Fig.

1, press it rearwardly with suilcientforce guide to llaterally 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 inclinedguide-member 30, it will bear against th'e vertical guide;

member 31 and be raised until its upper margin into the holder-member 33` When the receptacle strikes member 33, the hook flange 29 will slip backwardly above the upper end of guide member 30. The operator will then release'` the receptacle or exert a downward pressure on it to cause the hook-flange and the guide to positively interlock and secure th'e receptacle -in its operative position. In 'its upward movement,-

the receptacle will engage the cam 38 and rock lever 34 about its lower end so that cam 39 will raise plunger 40,l cause the pin 41 to bridge switch-members 24, 25 and close the circuit for the operation of the motor 10 and cause it to drive the agitatof'. Thisoccurs, preferably before the receptacle reaches its operative position. .The hook connection between 4the receptacle and the guide positively holds the receptacle, so that it will not be displaced b y the forward pressure of switch-lever 34, which is under the influence of spring 43, which tends to hold the switchthe operator will lower the receptacle and r press it backwardly,so that it will be held in the stationary guideway until it has been lowered to clear the agitator when it may be withdrawn forwa-rdlly. During the lowering of the receptacle, the switch-lever 34 will pass into its normaliposition to release plunger and cause it to break the circuit and stop the motor. This occurs preferably after the vessel has been lowered, to bring the liquid therein below the agitator, so the latter will run for a` period to discharge the adherent liquid by centrifugal force before the agitator leaves the upper end of the receptacl'e.

The invention exemplifies a machine of the character described, in which the receptacle is manually placed and/locked in its ope-ra.- tive position; in which such placement controls the motor; which is simple in construction and avoids the necessity of a shiftable agitator.

The invention is not to be understood as restricted tothe details set forth, since these may be modified within the scope of the appended claims, without`departing from the spirit and scope of the invention.
