DEIVE WHEEL ron EEA'rERs Original appdication iled August 18, 1921, Serial No; 493,382.` Divided and this application November 25, 1921.

To all 'whom it mayv concern Be it known that I, GEORGE VEssELL, a citizen of the United States,l and residingat Brooklyn, in the county of KingsV and Stat-e, of New York, have invented' certain new and useful Improvements in Drive Wheels,l for Beaters, ofl which the following is a speciication, such as will enable those skilled in the art to which it appertains tov make and use the same.

This invention relates to heaters and particularly to what are known as egg beaters, and the obj ect of the invention is t0. provide a drive wheel for devices of this class. which is of suc-h construction as to permit of the free and positive operation of the device at all tim-es, and which will eliminate the jamming or binding of such wheels with the beaters now commonly employed; and with this and other objects in view the invention consists in a drive wheel of the class and for the purpose specified which is simple in construction, efficient in use and which is constructed as hereinafter described and claimed. y

The invention shown and described herein is a division of application No. 493,382, filed by me August. 18, 1921 and is fully disclosed in the following specification, of which the accompanying drawing forms a part, in lwhich the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Fig. 1 is a sectional side View of the upper end portion of.l a beater showing my improved drive wheel mounted therein;

Fig. 2 a partial section on the line 2-2 of Fig. 1;

Fig. 3 a face view of my improved drive wheel detached; and,

Fig. 4 Ian edge view thereof.

For the purpose of illustrating one use of my improvement, I have shown in Fig. 1 of the drawing the upper end portion of a beater 5 of any kind or class and at 6 is shown the upper frame structure of the beater in which my improved drive wheel 7 is mounted, andV in said figure I have indi-cated at 8 the upper end portion of the lower end structure in which the beater blades '9 are mounted, and secured to said beater blades are pinions 10 the addendum circles of which are tangent and said pinions mesh with the drive wheel 7.

led serial No. 517,519. Y

The drive wheel 7 is preferably composed of sheet metal and provided centrally with oppositely directed sleeve bearingsv 11 throughwhich the shank of a crank handle 12; is adapted to pass and secured toi. said wheel whereby the rotation of said crank handle will correspondingly rotate the drive wheel 7.

The distinctive feature of the invention, or of the drive wheel 7 is in the formation of the teeth or projections thereof and in accomplishing this result the periphery portion of the drive wheel 7 is pressed laterally and alternately in opposite direc-tions to form recesses 13. and 14 on the opposite side faces of the wheel, and said recesses also form correspond-ingprojecting members or teeth 15 and 16 on the opposite faces; of the,` wheel. VIt will be noted that the teeth or projections 15 and 16 as well as the recesses 13 and 14 taper inwardly and radially of the wheel and are also arranged at an angle to the plane of the wheel or taper inwardly at right angles to the axis of the wheel as clearly shown in Fig. 1 of the drawing, whereby in the operation of said wheel in connection with the pinions 10 or the teeth of said pinion, as clearly illust-rated in Figs. 1 and 2 ofl t-he drawing, said pinions are capable of radial movement upon the drive wheel 7 whereby they may adjust themselves to predetern'iined positions on the tapered projecting members or teeth 15 and 16 of said wheel thus limiting any possible jamming of the drive wheel in or upon the pinions 10, or the pinions upon said drive wheel. Another distinctive feature of the invention resides in the fact that the teeth of the pinions 10 or the addendum circles thereof are tangent and the drive wheel passes therebetween and meshes therewith thus producing a strong and durable drive mechanism for beaters of the class specified.

Heretofore it has been customary to provide a straight face on drive wheels of the class under consideration, or a face in common alinement with the plane of the wheel in connection with which the pinions operate and the result of this construction is that if the drive wheel and pinions are properly fitted they have a tendency to jam, and if a loose fit is provided in order to avoid jamming the drive wheel has a tendency to slip by either one of the pinions in the operation thus destroying the utility of the device, and itis theprineipal object of my invention to avoid the above objections and to provide a gear construction for beaters of the class under consideration which may be properly fitted and in which the drive pinions will automatically adjust themselves to a freely operative position on the tapered teeth ort- projections 15 and 16 of the drive Wheel;

It will be understoodthat while I have shown a speciiic form of beater for illustrating one use of my improvement, I am not necessarily limited tothe beater con struction `herein shown and described, and various" other changes in and modifications of the invention may be made, Within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

`Having fully described my invention, what I claim as new and desire to secure by Lettersk Patent is 1 1. 'A `drive wheel for beaters of the class described, Vsaid beater `employing two drive pinions, the addendum circles of said pinions being tangent, said drive wheel being provided on the opposite facesthereof and at the periphery portion thereof with tapered semi-conical teeth or projections ranging radially and in the plane of said wheel and tapered from the periphery of said wheel inwardly, and the periphery portion of said Wheel being adapted to be positioned and operating between the teeth of said ainions.

2. A drive wheel for beaters, sai beater employing pinions the addendum circles of which are tangent, said wheel being provided on the opposite faces thereof With projecting radially tapered teeth and the taper of said teeth being continuous from the periphery of said Wheel inwardly, and the teeth of said wheel being positioned between the teeth of said pinions whereby the rotation of said Wheel will correspondingly rotate said pinions.

3. The combination with a beater employing pinions, t-he addendum circles of which are tangent, of a drive wheel, the periphery portion oi' which is provided on opposite faces with grooves and corresponding teeth substantially semi-circular in form in cross section, and the teeth of said pinions being' adapted to enter the grooves on the opposite faces of said drive wheel.

In testimony that I claim the foregoing as my invention I have signed my name this 22nd day of November 1921.

GEORGE VVESSELL.
