KITCHEN iriiiiivsIL."v

Applicationfil'edDecemberBI,15, 14 Serial No.8'73,832.

To an whom it may concern:

Be it known that I, EDWARD B. POGGEN- sen, citizen of theUnited States, residing at Chicago, in the county of Cook and State of Illinois, have invented acertain new and useful Improvement'in Kitchen Utensils, of which the followingv is a full, clear, concise, and exact description, reference being had to the accompanying. drawings, forming a,

part of this specification.

' My invention relates to pers.

of thebeater at a given locality and whereby small quantities of the fluid tobe beaten maybe kept in constant agitation.

My invention also has for its object the provision of an improved form of beater, the-use of which is enabled by the improved mounting thereof and which improved form of beater includes a. plurality of flexible strands which are desirably in theform of coiled metallic springs that are bunched to gether at the upper ends thereof and are free of mounting at their lower ends to permit them to spread apart in opposition to their own resilience in responsive to centi-ifugal force, the strands being spread apart and brought together as the beater is turned in reverse directions. The aeration of" the fluid undergoing the beating operation is of a structure made in accordance with the invention; Fig. 2 is a plan yiew, on a reduced scale, on line 2 2 of Fig. 1; Fig. 1s a view on line 3 3 of Fig. 1; and Fig. 4 1s a detail view, on a larger scale, of one of the strands of the beater.

a utensil for aerat- 1 ing fluid food elements and which are coin monly' known as egg beaters'or' cream whip-- The invention has for its general. object the provision of an improved mounting for the beating element of the utensil whereby the range of operation thereof is substantially fixed to enable the continued operation Fig. 1..


' The'vessel 1 (preferably substantially cy Specification of Letters Patent. v Patented Nbv.

I Like parts are indicated by similar char- 1 acters of reference throughout the diiferentlss lindrical upon its exterior-)1 in which the fluid to be beaten is disposed desirably has an outwardly'flaringmargin 2 over which the inwardlytapering rim .3 of a'atop or cover t may be sprung. The top lvis pro-;:

,Vided with a-central round opening .5 which is in axial alinement with the vessel: A ilower horizontal upwardly facing stationary raceway wall6 surrounds'and is'co-a-xial 7 withfthe opening The balls? ofa ball' bearing" structure are disposed in the annu-v lar groove in the lower "raceway wall 6 and are'received within the annular groove in an upper horizontal racewaywall 8; This'lat ter raceway wall is in'fixed relation-with'the shaft 9 ofthe beating element of the utensil,

spirally twistedbar of metal,rectangular in of this class; This threaded shaftpasses therein which closely approximates the cross section'ofthe shaft, as illustrated in Fig. 3,

this shaft. being desirably formed of a cross section, so as to constitute it a threaded 1 shaft whichiis so commonly. found in devices- The upperend o fthe shaft projects within a handlell and carries aspringseat 12-2111 its upper end in which is received the lower end "of a coiled spring 13 whose u perend has abutting engagement with the top wall" of-the handle bore as illustrated clearly in When the handle is depressed rotation ofthe shaft 9 is forced owing to its threaded 10, and when downward pressure upon the the handle) will serve to return the handle and thereby occasion a rotation of the shaft 'ment of such-a structure. The lower end 9O engagement with the. nonrotating ferrule handle is relievedthe spring 13 (which was. compressed on such downward movement of of the shaft is coupled with a sleeve 14, as by means of a cotter pin 15. This sleeve 14; constitutes amounting for a plurality of flexible strands 16 which are desirably metallic and resilient, these strands being preferably free at their lower ends to respond to centrifugal force in opposition to their own resilience. When the handle 11 is depressed rotary movement is imparted to the shaft 9 in one direction which will cause the strands 16 to fly apart and when the handle is released to'permit the spring 13 to function, the resilience of the strands will be first effected to cause their lower ends again to approach whereafter the strands will again fly apart when the spring 13 effects the. elevation of the handle.

The inner surface of the bottom of the vessel desirably conforms to a segment of a sphere whose center approximates the lower end of the sleeve. 1.4 so that none of the liquid within the vessel will be free of violent agitatinginfluence of the beater. In the preferred embodiment of the invention the resilient strands 16 are desirably formed of spirally wound resilient phosphor bronze wire. The strands are thus made of cylindrical formation with longitudinal bores and with opportunity for the passage of air between the helices thereof into such bores whereby the aerating or beatingfunction 0f the beater is materially improved. The top 4 constitutes the preferred form of mounting for preventing bodily movement of the shaft 9 longitudinally of itself but I do not wish to be limited to the location of the mounting nor to the confinement of the shaft to a fixed axis as I consider it to be broadly new with me to prevent the longitudinal movement of the shaft with re-- spect to itself irrespective'of the position it mayoccupy when such shaft is employed. in


the operation of the novel beater of my invention. V

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but

Having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. A fluid beating utensil which includes a fluid holding vessel; a beater projecting within the vessel and formed of metallic coiled springs free of mounting at their lower ends to permit the springs to spread in response to centrifugal force; and a hearing for rotatably supporting the beater to permit it freedom of movement at its lower 2. A fluid beating utensil which includes a fluidholding vessel; a beater projecting within the vessel and formed of metallic coiled springs free of mounting at their lower ends to permit the springs to spread in response to centrifugal force; an upwardly extending threaded shaft upon whose lower end the heater is carried; a handle in threaded engagement with the shaft to force the rotation thereof in reverse directions as the handle is reciprocated; and a mounting for the shaft for substantially preventing bodily longitudinal movement of the shaft while permitting the rotation thereof.

In witness whereof, I hereunto subscribe my name thistwenty-third day of December A. n, 1914-.
