EGG-IBEATER, CREAM-WHIP, AND MIXER.

Specification of Letters Patent.

Patented Nov. '7, 1916.

Application filed June 1, 1914. Serial No. 842,183.

To all whom it may concern Be it known that I, ABRAHAM KNoBEL, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented a new and useful Egg-Beater, Cream-Whip, and Mixer, of which the following is a specification.

This invention relates to agitators and aerator-s, such as eggbeaters, cream whips, churns and the like, and some of the objects of my improvement are, ease of operation; simplicity of construction; durability; ease and cheapness of manufacture; facility of cleaning; to avoid waste of the material treated; and facility of avoiding septic contamination in the operating element. These and other objects I attain by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation; Fig. 2, an edge elevation; Fig. 8, a top plan view of the beater blade; and, Fig. 4 is a bottom plan view of the same.

Similar reference numbers refer to similar parts throughout the several views of the drawings.

An upright standard or stand, 1, forms the frame, this is provided, at the upper end, with a handle, 2, for holding the beater firm with one hand while it is operated by the other hand. In the present instance I have formed the standard of a single rod, forming the handle 2 in the shape of a loop. In this way the handle serves at the same time as a means for hanging'the beater up on a pin in the wall or similar support. At the lower end of the standard 1 is provided an enlarged foot, 3, preferably made of wood, which provides a frictionalholding means by which the beater may be supported steady, on a table or other support while the material is being treated in an adjacent tumbler or other dish. This foot is rounded and smooth and, being of wood,

r will. not mar a finished table top or other furniture.

An arm, 4, extends substantially horizontally from standard '1: Upon this is mounted a large gear, 5, provided with a hub, 6, and a hand crank, 7. This gear is prefer ably journaled on a stud inserted in arm 4-. Meshing with gear 5 is a pinion, 8, similarly journaled on a stud, which is inserted in arm 4. On pinion 8 is mounted a beater crank, 9, provided. with a crank pin, 10, at its free end.

On crank pin 10 is mounted a beater blade, 11, to extend vertically downward toward the table upon which is placed the dish containing the material to be treated. The blade 11 is comparatively thin and wide and made of springy material, and is mounted to vibrate edgewise, so that it is rigid in the direction of vibration and application of force and cuts through the material with its thin edges, so as not to splash or throw the material out of the dish, as would be the case if a thick, round wire were used. At the lower end, the beater blade 11 is provided with laterally extending tines, 12, by which the material treated is agitated. These tines are preferably formed integral on the blade, by splitting and bending portions, laterally alternately. By this construction no cracks or crevices are left, to harbor decayed material and germs, and the blade is as easily cleaned as a table fork. The beating element thus formed, also, does not trap .or encage and thereby waste the material treated. It will also be understood that the tines are horizontally in the plane of their lateral motion, so that they present their thin edges to the material treated and cut through it laterally, but in their vertical motion their flat surfaces engage the material, so as to lift it in their upward path, carry it through the air, as indicated by the arrows in the tumbler, and carry it downward on the opposite side, thereby entrapping the air and quickly and thoroughly aerating the material. In this way very little force is wasted in merely agitating the material treated but the force applied by the operator is almost entirely used for aerating, and in less than one minute an egg or cream in a tumbler is beaten to a stiff, smooth froth that may be inverted and may not be shaken from the tumbler.

Intermediate between the beater crank pin and the tines the beater blade 11 is connected with stand 1 by means of a link, 13, which is pivotally mounted in the stand' and in the blade, 50 that the end mounted in the blade may vibrate, as shown by the dotted lines in Fig. 1. By this means the blade is mounted on a vertically reciprocating fulcrum, to which minimum friction is incident. It will. be understood that by this link the direction of rotation of the crank pin 10 is reversed in the tines 12, and the motion of blade 11 is almost entirely vertical at the upper edge of a tumbler, so that if the blade is operated in,

a tumbler full of liquid, there is scarcely any tendency to splash from lateral motion of the blade. This isoespecially advantageous in mixing and aerating drinks as well as in the beginning of the operation of whipping cream and churning to obtain butter. The motion of tines 12 is especially favorable for churning, and the saving of labor incidentto the thin blade and tines and the fulcrum link is remarkable.

The stand 1 is of such a height as to form a rest for the-operator while standing at a table using the beater. By providing a single point of contact for the standard, an operator grasping the handle 2 is enabled to tilt the beater in any direction to position the beater tines close to or away from the bottom of the receptacle, and can also shift the beater blade bodily from one side to the other of the receptacle without adjusting the supporting foot to another point of contact, the foot acting as a pivot in this instance, and is provided with a rounded lower end to facilitate the tilting of the beater as above mentioned.

Having now described my invention, so

that any one skilled in the art pertaining thereto may make and use it, I claim 1. A beater of the character described, comprising a beating mechanism including a beater blade and a standard therefor, said standard being spaced from said beater blade and provided with a single contacting point on its lower end which is adapted for free and tiltable engagement with a horizontal surface on the exterior of the receptacle in which the beater blade operates.

V .2.

4:. VA beater of the character described, comprising a beating mechanism including a beater blade, and a standard therefor, said standard being spaced from said beater blade, formed of a single rod having its upper end bent into a loop to serve as a handle, and provided with a single contacting point at itslower end which is adapted for free and tiltable engagement with a horizontal surface on the exterior of the receptacle in which the beater blade operates.
