C. E. KAlL EGG BEATER Filed Oct. 2. 1951 IN V EN TOR.

A TTORNEYZ Patented July 10, 1934 Application October 2, 1931, Serial No. 566,415

2 Claims.

My invention relates to improvements in egg heaters and has for primary objects the provision of a novel, simple and inexpensive one-piece gear frame and a novel and inexpensive and easy to assemble gear mounting.

It has been the primary purpose of my invention to simplify the construction and assembly of the gear supporting parts of an egg beater whereby to render them more economical to manufacture without sacrificing any strength or functional requirements of the parts.

Other objects and advantages will be apparent as the description proceeds, reference now being had to the figures of the accompanying drawing forming a part of this application and wherein like reference numerals indicate like parts.

In the drawing:

Figure 1 is a side view of an egg beater embodying my invention.

Figure 2 is a detail view of the gear frame in fiat blanked form.

Figure 3 is a detail view of the gear frame after forming to the required shape.

Figure 4 is a detail cross sectional view taken on the line 4-4 of Figure 1 showing the gear mounting and assembly.

Figure 5 is a detail cross sectional view taken on the line 55 of Figure 3 showing the formed structure of the gear frame.

The reference numeral 1 refers to the usual wire beater frame bent to substantially U-shape as at 2 and the free ends of which extend upwardly for fastening to the gear frame. Beater members 3 are suitably swiveled on the beater frame 1 and provided with pinions 4 at their open ends for engagement with the driving gear 5 by means of which the heaters are rotated.

The gear supporting frame comprises in this invention a novel one-piece blank indicated generally at 6 and bent as shown in Figures 1 and 3 to provide the upwardly extending side portions '7, the upper extreme free ends 8 of which are brought together and suitably secured within one end of a handle 9. The lower end of the gear frame, at the point where the same is bent upwardly as just described, is slotted as at 10 to permit the driving gear 5 to extend therethrough into engagement with the pinions 4. At this point and on either end of the slot 10 the frame is provided with ears or extensions 11 which in use are turned downwardly to provide a guard over the pinions 4.

The gear frame 6 is, as shown clearly in Figures 2 and 5, provided with a longitudinal bead 5'8 12 formed outwardly from the material of the Adjacent the lower ends of the beads 12 on each of the sides '7, the material is cut as at 18 and the cut portion of material pressed inwardly whereby there is provided adjacent the lower end of each side 7 a tubular receiving means for the upper ends of the beater frame 1, comprising the extreme lower bead portion 19 (see Figure 1) and the inwardly pressed bead portion 20 through which the ends of the beater frame pass. It will be noted that the bead 12 and the portions 19 and 20 thereof just described, are of such size 6 and shape as to fit snugly around the beater frame ends 1. The ends of the beater frame are suitably secured in this assembled portion by crimping or staking the same with respect to the embracing bead portions.

Secured upon the shaft 15 of the crank 16, for rotation therewith intermediate the sides '7 of the gear frame, is a stud 21 shouldered intermediate its ends as at 22 by means of flattening opposite parallel sides thereof as at 23. The

gear 5 is provided centrally with an opening having straight parallel sides adapted to fit over the shouldered portion of the stud 21 whereby the gear may be rotated therewith.

A shell or cover member 24 is provided over the flattened end of the stud 21 between the gear and the side 7 of the gear frame adjacent thereto whereby the appearance of the gear supporting assembly is the same on both sides of the gear, the shell 24 being of the same diameter as the stud 21.

The operation of the invention is believed to be obvious from the above description and emphasis is again placed upon the novel features consisting in the one-piece gear frame and the gear supporting structure. By these improvements, economy in parts, in manufacture, and in assembly is effected.

Of course, changes may be made in details of construction and arrangement of parts without departing from the spirit and scope of my invention. I do not limit myself, therefore, to the exact form herein described other than by the appended claims.

cup surrounding said flattened portion of said stud, and said cup being substantially the same outside diameter as said stud.

2. In an egg beater the combination with a gear frame comprising a unitary element bent to create a pair of substantially parallel side members connected by a slotted base member at adjoining ends, bearings at the ends of said side members, of a beater frame secured in said bearings, a shaft rotatably mounted in said side members, a circular stud fixed to said shaft having one end thereof flattened creating a central shoulder on said stud, a gear mounted on the frame of said stud and bearing against the shoulder and a spacer cup surrounding the flattened portion of the stud and bearing against the face of the gear opposed to the shoulder aforesaid.
