BEVERAGE MIXER.
Application filed January 14, 1922. Serial No. 529,133.
To all whom it may concern:
Be it known that I, Tnnononn A. Wonrnns, a residentof New York city, county and State of New-York, and a citizen of the United States of America, have invented certain new and useful Improvements in Beverage Mixers, of which the following is a specification.-
This invention relates to improvements in stirring or mixing devices, particularly for beverages one of the objects of the invention being to provide an electrically operated mixing device; the operation of whichis controlled by the positioning of the glass, which contains the beverage to be mixed, relative to the mixing device. A further object of my invention is to provide a mixing device-arranged so that a glass cannot be removed from the device until the mixing spindle has been entirely lifted out of the lass. Further features of improvement will fie pointed out in the description which follows.
I will now proceed to describe my invention in detail, the'novel features of which will point out in the appended claims, reference being had to the accompanying drawing, forming part hereof, wherein Fig. 1 is a vertical sectional view of my im roved device, partly in elevation;
*ig. 2 is a fragmentary plan view of the brake mechanism, other parts being omitted;
Fig. 3 is an enlarged sectional plan view,
. the section being taken on line 3-3 in Fig. 4 is a detail view of the switch mechanism'; and
Fig. 5 is a sectional view, the section being taken on a line 5-5 in Fig. 2', the wedge block being illustrated in elevation.
As one of the'objects of my invention is to provide 'a sanitary mixer, I provide a standard 6 which is designed to receive a glass 7 and to protect or cover the open end of the glass while the beverage therein is being mixed. :The stand 6 is provided with a cover-plate consisting of a fixed part 8 and a removable part 9 which hangs upon the flange 10 of the neck 11 suspended from the motor 12 which is also attached to the standard 6. -VVhen the glass 7 is placed in position, it will be slipped under the cover plate. At any time the removable member 9 of the cover can be taken off, should it be desirable to inspect the contents of the glass while the contents is being mixed. The mixing element consists of a spindle 13 provided w1th a spiral groove 14 which acts as a thread. The spindle 13 is carried by and passes loosely through the-core 15 of the motor armature 16. and is movable longitudinally of the said core. In this instance, the core 15 carries a head 17 having a pin 18 to engage the spiral groove 14. The lower end of spindle 13 carries an agitating device 19 of any suitable or desirable design. To the upper end of the core 17, I secure a hub 20 carrying a disk 21 having an annular flange 22 to act as a brake drum which acts in cooperation with brake shoes 23 and 24 pivoted together and to the member 25 of standard 6 at 26. The hub 20 yieldably supports a clutch sleeve 27 connected to said hub by a spring 28. One end of spring 28 is connected to sleeve 27 at-29, the other end of said spring being connected to disk 21 at 30. To the upper end of spindle 13, I secure a weight 31 having an inclined surface 32 to match the inclined end 33 of clutch sleeve 27. In the circuit for motor 12' is included a switch mechanism 34 consisting of contacts 35 and 36 carried by a block 37 of insulating material and a circuit-closer 38. The movement of the circuit closer is controlled (in this instance) by the movement of brakeporting a bracket 40 which in turn carries a roller 41 which is designed to coact with the cam portion 42 of the circuit-closer 37.
,When the brake shoes 23 and 24 are forced shoe 24 which carries an extension 39 supforced apart by the wedge portion 44 on ablock 45 secured to the upper end of a vertically movable post 46 which is actuated upwardly when a glass is placed in position, but drops when a glass is removed. When a glass is placed in position, it raises the outer end of a ivoted arm 47 upon which post 46 rests. 45 will rise, causing its wedge 44 to separate hen arm 47 is raised, block I actuating arm 47, I provide a stop I the shoes 23 and 24, thereby releasing the drum on core 15. The motor w ll now start to operate, because the circuit for the motor will close when said brake 5 shoes are separated. It will be understood that when a glass is to be inserted or withdrawn, the spindle 13 will be in its uppermost position, indicated by dotted lines n Fig. 1. The spindle 13 will return to ts 10 normal or uppermost position when the glass has been mixed and the motor stopped by moving the glass away from the switch 48 pivoted at 49 to the standard 6, said stop being normally held in a vertical position by a spring 50. When the glass 7 is in mixing position, the free end or point 51 of the 25 stop 48 will be located below the upper edge 52 of the glass; hence, should an attempt be made to withdraw the glass, it would strike stop 48 and further'outward movement will be checked. Movement of the stop, to release the glass, is prevented by a latch 53 pivoted at 54 to the fixed portion 8 of the cover. The longer arm of the latch 53 projects toward spindle 13 and the end thereof is positioned at the path of vertical movement of the mixing element 19 whichhas an inclined upper wall 19*. The latch 53 is actuated by gravity, in one direction, and by the upward movement of the mixer 19, in the opposite direction. Normally the spindle 13 will be in. its uppermost position (see dotted lines Fig. 1), at which time a glass can be placed in mixing position or 'removed therefrom. When spindle 13 is in its uppermost position, latch 53 will be p ositioned, as indicated by dotted lines in ig. 1, and switch arm 47 will also be in the position indicated by dotted lines.
To operate the device, a glass, containing elements to be mixed, will be slipped under the cover upon the base plate and moved toward the left in Fig. 1. Before the glass reaches its final position under arm 47, it will strike the stop 48 and move its lower end to the left until the upper edge of the 55 glass clears said edge, after which spring 50 will force the stop to full line position, Fig. 1. When the glass reaches its final position, switch arm 47 will be raised, thereby spreading the brake shoes 23 and 24 and also closing the circuit for the motor 12 which will now start and operate anticlockwise. As the spiral groove 14 is right handed, the spindle 13 will move down wardly, the weight 31 acting as a drag to 95 cause the spindle to lag; hence, said spindle brake-shoes, the motor will stop.
will be forced downwardly and will not rotate. As soon as the spindle has moved downwardly slightly, latch 53 will move to locking position, thereby preventing movement to the right, in Fig. 1 upon the part of the stop 48; hence, the glass cannot be removed. It will be noted that latch 48 is controlled entirely by the spindle 13 and cannot be operated exteriorly of the standard, as it is enclosed by the fixed portion 8 of the cover. The spindle 13 will move downwardly until weight 31, at the top thereof, comes in contact with sleeve 27, after which the spindle will rotate anticlockwise with the motor. After the contents of the glass have been mixed, the glass will be pulled away from arm 47, allowing said arm and block 45 to drop, thereby allowing spring 56 to move the shoes 23 and 24 into contact with the brake drum 22 and as the circuit for the motor will be broken by the contracting movement of the After the motor stops, the spindle 13 will continue to rotate anti-clockwise and hence will move to normal or dotted line position, thereby releasing latch 53, after which the glass can be removed. It will be apparent that a glass cannot be removed until the spindle has reached its uppermost position, in which position the mixer 19 will clear edge 52 of the glass. The resilient elements or arms 57 and 58 act as a brake to stop the spindle just before the lower end of the groove 14 reaches pin 18. The clutch elements 31 and 27, together with the clutchspring 28, act to connect the spindle and motor when member 31 contacts with member 27. To prevent the sudden starting of the spindle, in a rotary direction, is the function of the spring 28, which will yield and cause the connection to be gradual.
