Application filed. February 3, 1929. Serial No. 355,946.

T 0 all w hom t may concern:

Be it known that we, SAMUEL Raam and JOHN M. LANG, citizens of the United States, residing at New York city, Bronx county, and Yonkers, Westchester county, respectively, and in the State of New 'Yer-k, have invented certain new and useful Improvements in Beaters and Mixers, of which the following is a specification.

This invention relates to beaters, and mixers and especially to portable devices for beating eggs, cream, and similar articles of 'food and its obj ect is to rotate a beater whose spindle is journaled in the cap of a jar by means oli' a screw that is pressed downward into a tubedepending from said cap and containing a spring that returns the screw to its outer position.

The movement of the screw rotates a gear wheel confined in the cap and which actuates a pinion at the top of the beater spindle to rotate the latter with both movements of the screw and in Vorder to easily remove the beaten material the jar has an opening and cap at one side.

These and other objects and details of the invention are more fully described in the following specification, set forth in the appended claims and illustrated in the accompanying drawings, wherein:

Figure 1 is a vertical sectional view of the improved device.

Fig. 2 is a plan view of the same.

Fig. 3 is a horizontal sectional view on the line 33 of Fig. 1.

While beaters have been constructed whose motive power has been supplied by a screw, difficulty has been experienced in providing means to return the screw to its upper limit after such has been Jiorced downward and the present invention is designed to not only return a vertically reciprocating screw but to protect it i'rom the material being treated and to provide it with gearing to be energized so that the beater may be permanently located and the whole-carried by a removable cap.

The receptacle 5 is preferably a glass jar with a threaded neck 6, and having a lower opening T, on which is screwed a metal cap 8, containing the packing 9, to make it waterproof and prevent the escape of liquid contents. This opening` is sufficiently elevated above the bottom of the jar to provide for the average amount oi' cream or albumen to be contained therein without danger of leakage and the opening is to allow the reinovalof the froth or beaten material without removing the upper cap 10, and the beating mechanism. 1

The cap 10, is screwed upon the neck 6', and is .perfo ated at its center 'for the passage of the spindle 11, and its shank 12, the latter having at its upper end a pinion 18, and held in place by a plate 14, that is attached to the f upper side of the cap 10. The plate 14, also contines a gear wheel 15, perforated at its center so-as to conform with the threads. of a screw 16, that is adapted to play rapidly on account oi' its .elongated threads in the bearing 17, of plate 14, and a tube 18, that depends from the under side of the cap and which contains a spiral spring 19, that is adapted to be compressed by the screw, but which, when pressure is removed, forces the screw upward and outward. The lower end of the tube 153, carries a loop 20, that forms the bearing ior the lower end of spindle 11 and the latter carries the beater 21, that may be a frame of sheet metal or wires and secured to the spindle.

The screw as it passes through the gear wheel 15, rotates the latter, which also turns the pinion 13 and rotates the beaters and the rotation is reversed according to the way that the screwA is movine. At the top of the screw is a knob 22, which is held against rov tation by the hand or' the operator and this rigidity against rotation insures the proper operation of the gear wheels and the beaters. Y

With this arrangement of gearing it is evident that a very'high speed may be given the beater by proportion'ing'the wheels and it is Obvious that the devicel may be otherwise arranged or modified without departing from the essential features above described or from the scope of the appended claims. c

What we claim as new is:

1. ln a beater and mixer, the combination oi' a container having a perforated cap, a depending tube below the perforation, a stem penetrating the cap and having beaters at one end and a pinion at the other end, a plate on the upper side of the cap and securing the pinion, a pinion held against the v Y teet the screw from the contents of thereontainer, and a spring in the tube. adapted to 10 2. In a' beater and IniXer, the Combination of a container Cap, a stem journalecl in the same and having.;` beaters at its lower end, a pinion at the upper end of the stem, a perforated pinion'gearing with the first pinion, a serewadapted to play through the second pinion and rotate it, a tube adapted to proreturn 'the screw to its normal position.

3. In a beater and mixer, the combination of a Container. Gap, a stem journaled in the Cap, beaters at the lower end of the stein, a tube adjacent the stem and bracing same at its lower end, a screw adapted tol pass through the cap and play in the tube, a

spring to return the screw to the outside of the Cap, a pinion on the serew andadapted to be rotated by 1t, a knob on the screw, a

seeonol pinion at thev end of the stem and 20
