DRINK Application led July 8,

To all who/m, t may concern:

e it known that I, ELMER SAS, a citizen of Hungary, and resident of the city of New York, in the county of lBronx and State of New York, have invented certain new and useful Improvements in Drink Mixers, of which the following is a specification.

The present invention relates to improvements in agitating devices of the type generally used for mixing beverages at soda water fountains.

The main object of the invention is to provide a device of the type mentioned, whereby a plurality of drinks may be separately mixed at a time, the agitators being adapted to be operated successively, selectively or simultaneously.

Another object of the invention is to produce a drink-mixer of the character mentioned, which is simple in construction, eilicient in operation and the electric driving mechanism of which is automatically set in motion when any one of its receptacle holders is brought into operative relation to the respective agitating means.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanyfingwdrawings, in which Figure 1 is a top plan view of a drinkmixer constructed in accordance with the present invention; Fig. 2 is aside elevation thereof; Fig. 3 is a section taken on line 3 3 of Fig. 1, partly in elevation; Fig. 4 is a part of the section shown in Fig. 3, on a larger scale; Fig. 5 is a section taken on line 5 5 of Fig. 4; Fig. 6 is a section taken on line 6 6 of Fig. 3, on a larger scale; Fig. 7 is a section taken on line- 7-7 of Fig. 3, also on a larger scale; and Fig. 8 is a section taken on line 8 8 of Fig. 3, on a lar er scale.

n the drawings, the numeral 10 indicates MIXER.

1922. Serial No. 573,566.

a base plate, from which rises a plurality of tubular standards 11, supporting a housing 12 Within the housing is disposed an electric .motor 13, having a horizontally extending driving shaft 14, to which are fixedly secured in any suitable manne-r two friction disks 15, one on either end thereof. With-l each of these disks engages a driven disk or wheel 16, loosely mounted upon a shaft 17, that carries at its lower end agitating means 18. Each of these shafts is rotatably journa-led in bearings 19 and 20, which are connected by a U-shaped member 21. Each bearing 19 is longitudinally slid- 70 able in a boss 22, rising from the bottom of the housing 12. On each' bearing 19 rests a clutch member 23, that is pinned or otherwise secured to the respective shaft 17 and adaptedto be brought into engagement with a corresponding clutch member 24 on the' respective driven disk 16. A spring 25, inserted between the clutch member 23 and the respective driven disk 16, has a tendency to separate the clutch members.

With each agitator shaft co-operates a platform 26, that is suitably attached to a sleeve 27, forming a handle and being slidably disposed upon the adjacent standard 11. With each platform is associated a receptacle holder 28, in the form of a clip, that is fixed to a frame 29 on the respective sleeve 27. The clips are adapted to keep each a glass or similar container 28 in position upon the respective platform 26, and are, preferably, made in the form of springs, having tension varying means 30 of any suitable construction. In order to prevent a turning movement of the sleeves upon thel standards 11, each of thesaid sleeves carries a screw 31, which extends through a longitudinal slot 32 into the respective standard. This screw also serves to attach to the sleeve a short tubular member 33, that is disposed within the sleeve concentrically with the latter, it being spaced from the inner face of the sleeve by a ring 34, the latter being held in position by the screw 31. Each tubular body 33 extends above the respective sleeve 27, it being slidably mounted on a post 35 105 within the respective standard l1. In each standard is located a helical Aspring 36, one of its ends bearing against the respective ring 34 and its other end against a disk 37 on the lower end of the standard 11. The spring has a tendency to cause a movement of the respective platform 26 toward the l having a tendency to keep the nose projected platform in its lowered position.

into the standard 11 thereby holding the Each latch is adapted to be projected into an opening 43 adjacent the upper end of the respective standard, thereby holding the respective platform in its operative position 1n relation to sits agitating element.

To each of the slidable bearings 19 is pivotally connected at 44 a lever 45, that is fulcrumed at 46 to the housing 12. To each ofthese levers is pivoted at 47 a rigid link 48, which projects into the adjacent platform carrying 'standard and is provided at its free end with a disk 49, adapted to cooperate with the respective short tubular member 33. More particularly, when a platform 26 is raised into operative'relation to its agitating element, the respective tubular member 33 comesY into contact with the respective disk 49 and, upon completing its` upward movement, causes, by the intermediary o the respective link 48, an upward movement of the lever 45 connected therewith around its fulcrum 46, thereby bringing its clutch member 23 vinto engagement with the corresponding clutch member 24 on the respective driven disk 16, whereby the agitating element connected with said driven disk is rotated, provided that the motor 13 be driven.

In the motor circuit is inserted a switch 50, including a stationary contact 51 on an insulating body 52, the latter being held in any suitable manner within the housing 12. With the stationary contact co-operates a spring contact 53, xed by a terminal screw 54 to the insulating body. The spring contact extends substantially horizontally, its upper face being covered by an insulating -layer'55. The electric ywires lead from a suitable source of energy through one of the standards 11 into the housing, moreparticularly through that standard on which therev is no platform mounted. One of thesewires, denoted by the numeral 56, is connected to one of the brushes of the motor, while the other wire, denoted by the numeral 57, leads to the stationary contact 51. A-

wire 58 connects the terminal screw 54 with the other brush of the motor. With the spring contact co-operates a switch shifting 'Lavagna lever 59, that is fulcrumed at 60 to the housing 12. Une of the ends of this lever sis pivoted at 61 to a link 62, the latter having a longitudinal slot 63 adjacent its free end. Through this slot extends a pin 64, carried by one of the links 48. The lever 45 associated with the other link 48 has a projection 65, which is adapted to co-operate with a forwardly extending lug 66 on the switch shifting lever 59. The lug 66 projects above the spring contact l53, as shown in Fig. 5 of the drawings.

The operation of this device is as follows: l/Vhen both platforms 26 are in their lower positions, in which they rest on the base plate l0, the switch actuating lever 59 is in the position shown in full llines in Fig. 4l

of the drawings, its lug 66 being thus disengaged from the spring contact 53, whereby the motor circuit is open. The levers 45 are kept by springs 45 in the positions shown in Fig. 4 of the drawings, the clutch members on the driven disks 16 being thus disengaged' from the corresponding clutch members resting upon the respective shiftable bearings 19. If it is desired to mix a drink, a receptacle 28', with theunmixed contents therein, is placed in position on one of the platforms 26 within one of the clipsYY 28, after which the operator disengages the respective latch 38 from its respective standard, raising the platform and then again engaging said latch with the respective hole 43, above referred to.

During the raising movement, the respective tubular member 33 comes into contact with the disk 49 on the respective link 48, causing a corresponding movement of the lever 45 around its fulcrum 46, thereby engagi the set of clutch members and lixing t e respective driven disk 16 to its agitator shaft. If the platform shown on the left-hand side of Fig. 3 of the drawings is raised, the movement of its link 48 causes, by the intermediary of the link 62, a swinging of the switch closing lever around its ful- Crum 60, bringing the last-mentioned lever into the position shown in dotted lines in Fig 4 of the drawings, thereby causing a clos-r ing of the circuit of the motor. The agitating element on the left-hand side of Fig.v 3 of the drawings is thus set into action and the liquid mixed in the receptacle 28. t is to be observed from Fig. 4 of the drawings that the pin 64 engages the upper end of the slot 63 in the link 62. The levers 45 and 59 will thus move simultaneously.

With the elements shown in the positions of Fig, 3 of the drawings, the platform on the right-hand side of the said Fig. may he loaded with a receptacle and moved upwards into operative relation to its agitating element, the clutch memibers on :the agitator shaftv and the corresponding driven Bof disk being brought into engagement in the manner just now described,'the projection 65 on the lever 45 being shifted into engage ment with the switch shifting lever, which is already in closing position. When, however, the platform 26 on the right-hand side of Fig. 3 of the drawings is first raised, the projection 'on the lever 45 shifts the lever 59 into the yposition shown in dotted lines in Fig. 4 of the drawings, so as to close the switch. As this lever is shifted into closing position, the link, 62 must obviously move therewith. It is for this reason that the longitudinal slot 63 is'provided in the last-mentioned link.

From the foregoing it appears that a plurality of drinks maybe mixed simultaneously or successively, the circuit of the elec- ,trlc motor being adapted to be closed by the movement of either platform and held in closed position as long as either one of the platforms is kept in operative relation to itsagitating element. The agitating elements are thus..y adapted to be operated successively, selectively or simultaneously, they having acommon driving element, which is set into action by bringing either one of the receptacle carrying platforms into operative relation to its agitating element.

Whenever a drink has been mixed to the desired degree, the respective platform is lowered, thereby permitting the receptacle to be removed therefrom. When both platforms are in their lower positions, obviously the electric circuit is interrupted and the motor brought to a stop.

What I claim is l. A drink-mixer, comprising a frame, an electric motor thereon, a plurality of agitating elements, means associated with each agitating element capable of independently gearing the same to said motor, a relceptacle carrying each agitating. element, said platforms being slidably mounted on said frame, a switch in the circuit of said motor, and means for closing said switch, said rswitch closing means being adapted to' be actuated by each platform when the latteris shifted on said rame into operative relation to its agitating element.
