Specification of Letters Patent. I

Patented Feb. 15, 1916.

Application filed May 10, 1915. Serial No. 27,013.

To all whom it may concern.

Be it known that I, ADOLPH THORMAHLEN, a citizen of the United States, residing at New York, in the-county of New York and State of New York, have invented certain new and useful Improvements in Drink- Mixers, of which the following is a specification.

This invention relates to drink mixers and 1 tain or the like, the clerks are usually very busy and it is important that the drink mixing mechanism employed shall be capable of speedy manipulation.

It is a further object of the invention to provide an article of the character set forth employing a plurality of agitators, any of which may be independently driven so that one or more of said agitators may be employed at a time for the purpose of mixing drinks.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawings :.Figure 1 is a view partly in side elevation and partly in section of a drink mixing machine comprising two agitators; Fig. 2 is a sectional view illustrating one of said agitators in its raised position; Fig. 3 is a plan view illustrating a slightly modified form of the device employing four agitating mechanisms; and Fig. A is a perspective view illustrating a bayonet slot connection hereinafter described. I

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing, the numeral 5 designates'the casing of an electric motor, not shown, and to which current may be supplied through conductors 6 and 7. The motor drives a shaft 8 carrying a bevel friction gear 9. This gear drives a bevel friction pinion 10, when the bevel friction pinion is brought into the position illustrated in Fig. 1. This bevel friction pinion is carried by a sleeve 11 which rotates in a bearing 12 of extension 13 of easing 5. A pin 14 carried by sleeve '11 passes through an elongated slot 15 in a stem 16 of agitator 17. A light spring 18 bears against the lower end of sleeve 11 and normally tends to raise said sleeve, and the friction pinion 10 out of engagement with the friction gear 9. A cap 19 carries a sleeve 20 which contains a spring 21 and a ball 22, said ball bearing against the upper end of the stem 16. The sleeve 20 carrles a pin 23, the inner end of which projects into an annular groove 24 formed in the stem 16, and the outer end of which is adapted to engage in the elongated part 25 of a bayonet slot 26 formed in the bearing 12. The operation of the device is as follows: v 1

Assuming that the parts are in the position as illustrated in Fig. 2, it is apparent that the drinking glass 27 may be placed in position beneath'agitator 17. The operator then presses downwardly upon knob 19 until the parts liein the position illustrated in Fig. 1. During the downward movement of knob 19, the top of the slot 15, indicated at 15 strikes against pin 14 and forces the sleeve 11 and bevel pinion 10 downwardly against the tension of spring 18 until said bevel pinion comes into operative engagement with the bevel gear 9. It is to be understood that the spring 21 is strong enough to accomplish this end. The outer end of pin 23 then enters the bayonet slot 26 and a turn of the knob causes said pin to enter. the elongated part 25 of said slot to hold the parts in their lowered position. The factthat pin 23 engages the annular groove 24: of stem 16 results in preventing disengagement of cap 19 from the stem when the parts are in their raised position to permit rotation of the stem with relation to the cap.

The structure shown at the right hand side of Fig. 1 is duplicated at the left hand side thereof and the same reference numerals have been applied. However, the invention is not limited to the use of only two agitators, but, upon the contrary, four agitating mechanisms may be employed as illustrated in Fig. 3. In this case 19 designates the caps of agitating mechanism like that shown in Fig. 1, the only difl erence being in the number of mechanisms employed, and it is to be understood that the number may be varied at will. The employment of the bevel friction drive as herein shown and described renders it unnecessary to employ toothed gear wheels which are noisy inoperation, and consequently, objectionable for use in well fitted establishments. Furthermore, the employment of the bevel gear drive as herein shown and described renders it possible to move the parts into engagement with each other with a minimum of trouble, and also renders it possible to provide a plurality of mixing mechanisms and to drive one or more of them independently of the other.

\Vhile the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview, whatever is new and within the spirit of the appended claims.

Having thus described my invention, what I claim is:

1. In a device of the character described, the combination with a rotative driven member, a stem slidable therethrough, an agitator carried by said stem, means for driving said stem' from said member, means normally tending to elevate said member, and yielding manually operable means arranged to thrust said member downwardly against the action of said elevating means.

2. In a device of the character described, the combination with a casing having a 1'0- tative bevel gear mounted therein, of a rotative pinion arranged to contact with said gears-a bearing carried by said casing, a sleeve carried by said pinion and mounted to rotate in said bearing, a stem passing through said sleeve and through said pinion. spring means normally tending to elevate said pinion and said sleeve, a pin carried by said sleeve which passes through an elongated slot in said stem, a cap, spring means bearing between said cap and apart of said stem, and means for holding said cap against upward movement.

lln a device of the character described,

the combination with a casing having a rotative bevel gear mounted therein, of a rotative pinion arranged to contact with said gear, a bearing carried by said casing, a sleeve carried by said pinion and mounted to rotate in said bearing, a stem passing through said sleeve andthrough said pinion, spring means normally tending to elevate said pinion and said sleeve, a pin carried by said sleeve which passes through an elongated slot in said stein, a cap, means for holding said cap against upward movement, a spring located in said cap and a ball upon which said spring bears, said ball having a seating upon the upper end of said stem.

4. in a device of the character described,

the combination with a centrally arranged driven bevel gear, of a plurality of beveled pinions arranged thereabout to Contact therewith and be driven thereby. means normally tending to impart upward movement to said pinions, stems passing through said pinions, agitators .carried by said stems, and manually operable means for thrusting said pinions downwardly against the action of their elevating means to bring them into engagement with said bevel gear as and for the purposes set forth.

5. In a device of the character described, the combination with a horizontally disposed rotative driving element of a horizontally disposed rotative driven element, means normally tending to impart vertical movement to said driven element to move the same out of engagement with the driving element, a sleeve carried by said. driven element, an agitator vertically movable with relation to said sleeve to rotate therewith, a manually operable member for moving said agitator, a fixed bearing member in which said sleeve turns and a bayonet joint connected between said manually operable member and said bearing member.

6. In a device of the character described, the combination with a centrally disposed beveled driving disk, of a plurality of beveled pinions disposed about the periphery of said disk and movable vertically into and out of engagement with the periphery of said disk, sleeves to which said pinions are connected, a housingfor inclosing said disks and pinions, springs beneath said pinions and bearing between said pinions and a part of said housing, an agitator rod passing through the sleeve of each of the pinions,a'cap located above each of the pinions, bearing members carried by the' housing in which the sleeves of the pinions rotate, sleeves carried by said caps and projecting into said bearing members, pins projecting through the sleeves of the caps, said agitator rods having cut-out portions in which the inner ends of the pins engage, springs bearing between said caps and the upper ends of the agitator rods, there being suitably shaped grooves formed in the bearing members and cooperating with the outer ends of said pins to establish bayonet joints between the sleeves of the caps and said bearing members.

In testimony whereof ll afix my signature in presence of two witnesses.
