SPECIFICATION forming part of Letters Patent No. 511,637, dated December 26, 1893.

Application filed Se tember 29, 1892. Serial No. 447,294. (No model.\

To aZZ whom it may concern:

Be itknown thatI,BARTLEYDMoDoWELL, acitizen of the UnitedStates, and a resident of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Stirring or Mixing Untensils; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in stirring or mixing utensils for culinary and other purposes and consists in the matters hereinafter described and pointed out in the appended claim.

In the accompanying drawings illustrating my invention: Figure 1 is a view partly in elevation and partly in section, of a mixing implement constructed in accordance with my invention. Fig. 2 is avertical sectional view of the same taken on line 2-2 of Fig. 1. Fig. 3 isa detail sectional view of one of the parts, taken on line 3-3 of Fig. 5. Fig.4 is across sectional view of the same taken on line 4:4: of Fig. 5. Fig. 5 is a top plan view illustrating the construction of the joint between the frame of the mixer and thesupportingbracket.

In said drawings A represents a suitable supporting arm upon which the operating parts of the mixer are mounted, this arm being adjustably engaged with a bracket B which is adapted for engagement with the edge of a table or shelf and is provided with a suitable clamping screw 1), for securing it thereto. A suitable gear wheel 0 is journaled upon a spindle c at the outer end of the arm A, and is provided with an operating handle or crank O by which it may be rotated.

A projection 41 upon the under side of the arm A, carries a vertically disposed sleeve a within which is journaled a shaft cl carrying at its upper end a pinion D which meshes with the teeth of the gear 0, as shown more particularly in Fig. 2.

Rigidly supported at the lower end of the sleeve a is a gear wheel E, anda suitably shaped frame F is rigidly secured to the lower end of the revoluble shaft (Z, by means of a suitable key or pin f.

Two stirrers G G, of any desired or con venient form are revolubly supported in the frame F. These stirrers G G, in the particular form of construction shown in the draw ings, are made up of any desired number of bars or rods constituting an open work grating or frame. At the top and bottom respectively, of said stirrers are provided spindles g g and g g, which are journaled in the upper and lower portions of the frame F. Upon the upper ends of the spindles g g are rigidly secured gears G G arranged to mesh with the stationary gear E at the lower end of the sleeve a. It follows from this construction that when the gear wheel 0 is rotated, motion will be communicated by said gear to the pinion D and shaft d upon which the same is secured. This rotation of the shaft d will obviously cause the frame F secured thereto, to revolve and carry the stirrers G G and the gears G G around, and this planetary movement of the gears G G will by reason of their engagement with the stationary gear E, cause said gears to revolve upon their own axes which rotation will be transmitted to thestirrers G G in an obvious manner.

The gearE is preferably made of considerably greater diameter than the gears G G, so that the rotation of the stirrers upon their respective axes will be at a very considerably more rapid rate than the rotation of the frame F upon its axis,

I find it convenient to arrange the arm A so as to be adj ustably engaged at its end A, with a projection 13 on the supporting bracket B, and to this end, I provide said parts with flat bearing surfaces, and a screw 1) is passed centrally through said parts and serves to bind them securely together in their adjusted positions. In order to more securely hold the arm A in its adjusted position, I provide upon one of the flat bearing surfaces suitable radially disposed grooves o a and upon the opposite bearing surface of the other part, a radial rib 11 adapted for engagement with any desired one of the said grooves a? a By this construction, the arm A may be readily adjusted upon the bracket B by loosening the screw Z) and swinging said arm with the mixer into the desired position, and then turning said screw up so as to bind the arm A to the bracket B in an obvious manner.

In practice I prefer to clamp the bracket B to the edge of a table, shelf or other suitable support, and to support the vessel containing the material to be agitated or mixed in such a position that the bottom of the frame F will come close to the bottom of said vessel, when the stirrer is in the position illustrated in Fig. 1. l

The arm A may be thrown upward to raise the frame F and the stirrers G- G above the level of the vessel, so as to permit it to be placed in proper position, and then moved back into the position shownin the drawings to bring the said frame stirrers down into the vessel. I prefer to provide upon the bottom of the frame F, a pointf projecting downwardly therefrom in the axial line of said frame, and adapted to rest upon the bottom of the vessel to keep the lower side of the said frame from dragging against the bottom of the vessel and also to form a pivotal support upon which said frame rotates.

By my improved construction, the frame F rotating upon its axis, tends to bring the material under treatment: toward the center of the vessel, and the independent rotation of the stirrers G G tends to throw the said material toward the outside of the vessel, While by the planetary movement of said stirrers about the axis of the frame F, they are brought into contact with every particle of the mate rial. In this manner, the material under treatment is very thoroughly agitated and the ingredients very intimately mixed together, and the Work of stirring or beating, or of mixing ingredients together may be performed in a small fraction of the time usually required for said operation when performed by hand and with a minimum expenditure of labor.

My improved mixing or stirring utensil is adaptedfor use for a great number of purposes, and I find it exceedingly efficient in all instances where a thorough agitation, aeration, or mixing together of materials is.required.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

A stirring or mixing utensil comprising a bracket adapted for engagement with a shelf or other support, an arm adj ustably engaged with said bracket, a revoluble shaft journaled in said arm and carrying aframe, independently revoluble stirrers carried by said frame each -composed of suitable side pieces orbars and a series of transverse bars extending be tween the same, a stationary gear concentric with said shaft, and planetary gears upon the axes of said st'irrers and arranged to mesh with said stationary gear, substantially as set forth,

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wiscousin, in the presence of two witnesses.
