SPECIFICATION forming part of Letters Patent No. 785,114, dated March 21, 1905.

Application filed May 9, 1904. I Serial No. 207,012.

To @ZZ whom, 'it may concern.:

Be it known that I, GEORGE M. MUNN, of Fitchburg, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Egg-Beaters; and I do hereby declare that the following` is a full, clear, and exact description of the same.

This invention relates to stirrers and beaters, and particularly to a device designed for use as an egg-beater.

An object of this invention is to provide novel means for anchoring and rotating the beaters, the said beaters being so secured'as to permit their looped ends to stand away from the central standard by reason of the centrifugal force incident to the rotation of said beater, thus causing the said beaters to describe a larger circle in their movement than they do when the said beaters are in their normal position and the circle described being proportional to the speed at which they are rotated.

Furthermore, an object of this invention is to provide novel means for rotating the beaters independently of the central standard, which forms a support for theoperating mechanism.

Furthermore, an object of this invention is to provide novel means for mounting the power-wheel with relation to the frame and the pinion which carries the beaters; and the invention further contemplates the provision of means for anchoring the ends of the beaters with relation to the pinion in order that an ordinary pinion may be utilized and in which the construction is simplified.

Finally, an object of this invention is to provide an egg-beater of the character noted which will prove simple in its construction and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and specifically claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, wherein like characters denote corresponding parts throughout the several views, in which- Figure 1 is a perspective view illustrating an egg-beater embodying the invention. Fig.

2 is a sectional view on the line X of Fig. l, with Jfragments of the beaters in elevation and with the gear-wheel removed. Fig. 3 is a sectional view through the power-wheel and its supporting member.

In the drawings, A indicates the standard, terminating at one end in a handle a and at its opposite end in a bracket d, the said bracket being approximately C-shaped. Intermediately the length of the standard A is a boss B, which has a ared opening b for the reception of the pivotal pin the said pivotal pin b having mounted thereon the gear-wheel C, which is designated as the power-wheel and is provided with a crank-handle c for the purpose of rotating the said wheel. The pivotal pin is preferably swaged in the opening of the boss, and the gear-wheel c is rotatable thereon.

The bracket at the end of the standard has its outer portion recessed, as shown at c2, for the accommodation of the beaters and a supporting-rod, (to be hereinafter described.) Within the C-shaped portion of the bracket I mount a pinion D, having acentral opening UZ for the reception of the core E, the said core having peripheral recesses e extending from its outer surface and terminating a suitable distance from the opposite surface of the said core. When the core is applied to the pinion, sockets are formed which are designed for the reception of the ends of the beaters F, said ends being anchored in the sockets by brazing or in any suitable manner. The beaters comprise strips of metal, preferably wire, bent on themselves to form the loops f, and the two ends of each beater are anchored with relation to the pinion in the manner heretofore described. The supporting-rod Gr extends through the core and has its end secured to the standard A by brazing or otherwise, and the said rod G forms a shaft around which and on which the core of the pinion rotates. The pinion is prevented from displacement by the portions of the brackets c', as will be fully apparent from an inspection of Fig. l.

In operation when the gear-wheel O is r0- tated by means of the crank-handle the pinion D is turned, and as the core E is secured to rotate with the pinion the beaters F,which IOO have their ends anchored in the core, are also rotated. As the loops f of the beaters are independent of each other and of the rod G., the. centrifugal force due to their rotation Will cause them to move away from the rody and beat the contents of areceptaclein connection with which the said beater is operated.

The core E and pinion D may be secured together in any suitable manner, though inn.

practice the ends of the beaters could be braZed'/.'

I claim as new, and desire to secure by Letters Patent, is-

In an egg-beater, a standard terminating at one endl in a handle and at the opposite end in a bracket, a gear-Wheel pivoted intermediate the standard, a pinion mounted in the bracket and meshing With the gear-wheel, said pinion having an opening, a removable core fitting in the opening, said core having' peripheral r cwssfesextendingirom the outer surface of the to the pinion and core at the saine time;r thul and terminating a suitable distance from making the parts practically i/ntegral and mini-r mizing the cost of the construction.`

The operation of this invention and the details Will, it is thought,v be understood from the foregoing description, it being noted that various changes may be resorted to in the proportions Without departing from the scope of the invention. I

Havingfully described the invention, what "the oppositesurface of said core, said recesses forming .sockets when the core 1s applied, beaters anchored 1n the sockets and a supporting-rod passing through the core and secured at one end to the standard.
