' 12 claims. (cmi-,432i
parts, all as hereinafter more lfully described,`
claimed and killustrated in the accompanying drawing, wherein:
Fig. 1 is aside elevationY of a gear embodying. the present. invention illustrating the same' as the driving gear of an egg beater; and
Fig. 2 is an edge elevation thereof. s
While the present gear and its hub eral application and use, it is designed particularly for use as the driving gear of an egg beater wherein the gear is mounted between the sides of the beater frame and acts to space the sides of the frame.
Heretofore, it has been customary in order to mount the driving gear between the sides of the frame of an egg be-ater to provide a hub consisting of one or more individual pieces secured to the gear at its center and projecting outwardly from the body of the gear to bear against the inner surfaces of the egg beater frame. This type construction preventsI any lateral play or displacement on the part of the gear and at the same time spaces and braces the sides of the egg beater frame. The gears of the prior art including hubs made up of a number of separate parts has been diflicult and expensive to construct and assemble.
The present gear is designed to -accomplish the purposes of the prior art gear and at the same time have all of its elements of the hub thereof formed integrally with the body of the gear, thereby reducing the number of parts as well as the steps of construction and assembly.
Reference being had more particularly to the drawing, I0 designates the frame of an egg beater provided with a handle Il. The sides I2 of the frame I0 are spaced one from the other and rest parallel and at their lower ends are provided with mountings or bearings I3 in which the beaters I4 are mounted for rotation. Adjoining the lower ends of the sides I2 of the frame I0 and secured to the beaters I4 are gears f5 by which the beaters I4 are driven and rotated. A driving gear I6 is mounted between the sides I2 of the frame lll and meshes with the gears I5 whereby the rotation of the driving is of gent gear I6 causesthe'rotation ofthe gears I5 and lconsequently the beaters I4. p
- In order to create a hub at the center of the gear I6 in such-form as to prevent any lateral play or displacement of the gear I6 and to ll the space between the sides I2 yof the frame, the bodyy of the` gear II.V at each side of the center thereofis cutl to create a tongue I1, the inner end of whichisA integral with the body of the gear at a point adjoining the center thereof. The formation of these tongues I1 from thebody ofthe gear I6 creates a pair of diametrically disposed openings I8 in the body of the gear resting along a diameter lof the gear and extending from the center of the gear.y toward the periphery thereof. -These tongues I 'I are bent laterally to rest atA right angles to the body of the gear i6 and extend outwardly topointsad-l joining the inner surfaces of the sides IZ of the frame I0. Here each tongue I1 is again bent at right angles to create a bearing member I9 parallel to the gear I6 and extending across the line of the center of said gear to terminate approximately in the plane of the right angularly bent portion of the opposed tongue I'I. The body of the gear I6 vat its center and the bearing members I9 of the tongues I'I which cross the line of the center of the gear I6 are each provided with a rectangular aligned opening 20 for the reception of the driving shaft 2|.
The driving shaft 2I is rectangular in cross section and passes through circular openings in the sides I2 of the frame I0 and is received in and passes through the rectangular openings 2B in the gear I6 and bearing members I9 so that the shaft 2l is free to rotate in the sides I2 of the frame I0 and is rigidly and fixedly connected or keyed to the gear I6 and to the bearing member I9 whereby the rotation of the shaftZI rotates the gear I6. At one end the shaft 2l is provided with a crank or handle 22 adjoining the outer face of one of the sides I2 of the frame I0, while the opposite end of the shaft 2i is headed up, as at 23, against the outer face of the opposite side I2 of the frame II).
It is to be observed that as each of the bearing members I9 of the hub above described operates against the inner face of one of the sides of the frame I0, the gear I6 is held against lateral displacement upon the shaft 2l or between the sides I2 of the frame I and the latter are reinforced and maintained in their spaced positions.
It is also to be noted that the gear I6 is provided with an integral hub, the construction and formation of which is relatively inexpensive requiring no assembling whatever.
What is claimed is:
1. The combination with a gear, of a tongue formed and spaced from said gear, said tongue having a shaft receiving opening therein.
2. 'I'he combination with a gear having an aperture in the center thereof, of a tongue formed from the body of the gear'at one side of said aperture and bent to occupy a position at right angles to the body of the gear, the end of said tongue being lateral to cross the line of the center of the gear.
3. The combination With a gear having an aperture in the center thereof, of a tongue formed from the body of the gear at one side of said aperture and bent to occupy a position at right angles to the body of the gear, the end of said tongue being laterally bent to cross theline of the center of the gear and having an opening therein in alignment with the opening in the center of the gear. y
4. The combination with a gear having aY central aperture therein, a tongue formed from the body of the gear on each side lof the aperture, said tongues being positioned. at right angles to the body of the gear upon opposite sides thereof and having their ends bent laterallyto cross the line of the center aperture of the gear.
5. The combination with a gear having a central aperture therein, a tongue formed'from the body of the gear on each sideof said aperture, said tongues being positioned at 'right angles to the body of the gear upon opposite'sides thereof and having their ends bent laterally to cross the line of the center opening of the gear, said tongues having openings in the laterally bent part in alignment with the center aperture of the gear.
6. 'Ihe combination with a disc, of dametrcally disposed tongues fonned from the body of the said disc and bent to occupy positions at angles to the disc and having shaft receiving openings adjoining their extremities. 5
'7. 'Ihe combination with a disc, of diametrically disposed tongues formed from the body of the said disc and bent to occupy positions at right angles to the disc, the ends of said tongues being bent laterally to the bodies thereof to cross the l0 pivotal line of the disc.
' 8. 'Ihe combination with a. disc, of diametrically disposed tongues formed from the body of the said disc and bent to occupy positions at right angles to the disc, the ends of said tongues being 15 bent laterally to the bodies thereof to cross the pivotal line of the disc, said disc and tongues being provided with aligned apertures.
9. A gear comprising a disc having an opening therein, and a tongue formed and spaced from 20 said disc and provided with an opening aligned with the disc opening.
10. A gear comprising a disc having an opening therein, and tongues formed and spaced from said disc and upon opposite sides thereof, said 25. tongues having openings aligned with the disc opening.
11. IThe combination with a disc, of tongues spaced from said disc, said disc and tongues having shaft openings aligned transversely of the 30 disc and tongues.
l2. The combination with a disc, of tongues integral with said disc and parallel thereto, said disc and tongues having shaft openings aligned transversely of the disc and tongues. 35-
