EGG BEATER Filed May 13, 1935 Julius fiflordla g Leonard Helland INVENTORS ATTORNEY Patented July 31, 1934 Julius E. Nordby and Leonard Helland, .Moscow, Idaho s i Application May 13,1933, SerialNo. 670,900v

1 Claim lCl. 259-131) Ourpresent invention. relates to improvements in egg beaters of the rotary, hand operated, crank and gear type employing a pair of separable beaters which may readily be removed and re- 1 5 placed, in order that the several parts of the device or implement may be thoroughly washed and dried when required, to maintain the implement in clean, sanitary condition.

As is well known to those familiar with the ,0; culinary art, difficulty is encountered and much time is ineffectually employed in the attempt to successfully wash and dry the non-separable type of egg-beaters, and in the separable type of egg beaters, it is desirable and necessary that the 5 devices shall not only be securely retained against displacement of the beaters while they are in operating position, but the construction and arrangement must also be simple, and not intricate, in order that the housewife, or the helper, may,

2Q without difficulty and without undue labor, displace the separable beaters for cleaning. Another requisite for the desirable and efiicient implement is the ability to restore the beaters to operative position without the necessity for ex- 5: pert labor, and without necessity for resorting to unusual force in assembling the separated parts of the implement.

In carrying out our invention we provide an implement which is comparatively simple in construction and operation, which may be manufactured at a low cost of production, and from which the beaters may, with convenience and dispatch, be readily separated, and with equal facility these separated beaters may again be 3 assembled in position for use.

Our invention consists in certain novel combinations and arrangements of parts in the separable beater as will hereinafter be more fully set forth and claimed. In the accompanying 0 drawing we have illustrated the invention in the best modes we have so far devised for the practical application of the principles of our invention.

Figure 1 is a view in elevation of an egg-beater i-embodying our invention, showing by dotted lines the mode employed for removing or replacing one of the beaters, and Figure 2 is a view in elevation of the beater, as seen from the right in Figure 1.

Figure 3 is an enlarged detail view, partly in section, showing the lower journal bearings for the heaters, and Figure 4 is a detail view, partly in section, showing journal bearings at the upper ends of the beaters.

In the preferred form of the invention, as illustrated in the drawing, we'employ a main frame 1 having a rigid handle 2 which is grasped, as in the left hand, for holding the beater in operative position, and a main gear wheel 3 is journaled at 4 in the main frame. The main gear wheel is fashioned in the form of a sheet metal disk, and at opposite sides thereof the metal is struck from the body of the disk to form the annular series of teeth 5, thereby providing an annular series of teeth near the outer periphery of, and at each side of the circular disk or wheel. The wheel is revolved in its bearings through the use of a crank 6 which is provided with a handle or loose knob '7, and the latter is grasped, as in the right hand, and turned for operating the beater.

The main frame, at its lower end, is provided with a head portion 8, and the beater frame 9 is rigidly attached to this head. Preferably the beater frame is fashioned as a bowed, or U- shaped body, of resilient metal, and as indicatedby dotted lines in Figure 2, this frame may be compressed as to its width and thereby extended in length to facilitate the separation from the implement of the two beaters indicated by the numerals 10 and 11. The beaters are of usual type and circular in form, and each beater is provided with a spindle 12 at the upper end of which a reduced extension 13 forms a journal pin, and the pinion 14 for each beater is fitted over this pin and seated on the shoulder or abutment 14'. The pinions are thus securely mounted on the heaters and they are located one at each side of the gear wheel for co-action therewith in rotating the beaters.

Each beater, at its lower end, is also provided with a lower journal pin, axially alined with its upper journal pin 13, and these lower pins are designated by the number 15.

At the lower end of the beater frame a cross head 16 is rigidly mounted on this frame and at the opposite ends of the cross head bearing holes 1'7 are provided for the reception of the journal pins 15. As best indicated in Figure 3 the upper face of the cross head is fashioned with alined grooves 18 that extend outwardly from the holes 17 and terminate with rounded or downwardly turned ends at the respective ends of the cross head. Thus, as indicated in Figure 3, the cross head is of resilient metal and the opposite ends of the cross head may be depressed to permit dislodging of the pins 15, and the pins then slip along the grooves 18 as the beater is being separated from the implement. In assembling the beater in place, the pin is slipped along the groove, (and the end of the resilient cross head is bent down if necessary) until the pin is snapped into the hole 17, the groove thus acting as a guide for the pin as the beater is removed or replaced.

In Figure 1 the frame 9 may be compressed as to its width, as indicated by dotted lines, to extend the length of the frame, and the hole 17 is thus disengaged from the journal pin, after which the pin is slipped outwardly, through the guide groove. The compression laterally, and extension longitudinally of the beater frame, and the resiliency of the cross head 16 both contribute to ease and convenience in removing and replacing the beaters.

The upper ends of the heaters are also readily detached and attached with a snapping action by the use of resilient bearing arms 19 on the head of the main frame, and these arms are provided with hearing or journal holes 20 for the upper journal pins 13 of the heaters.

Thus, it will be apparent that, with the left hand grasping the handle 2, the right hand may be used to grasp a beater, and the upper and lower pins of the beater'are disconnected from their bearings with only a slight exertion, to separate the heaters from the implement, and with equal facility, these heaters may be replaced.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:

In an egg beater, the combination with a main frame and a heater frame rigid therewith, said heater frame comprising a U-shaped yoke of resilient material adapted to be compressed laterally for causing longitudinal extension thereof, oppositely extending resilient arms having bearing holes and rigid with the main frame, a cross head of resilient material having its central portion rigid with the free end of the yoke and spaced bearing holes in said head, and said cross head having in its upper face guide grooves leading from its free ends to said holes, of a pair of separable heaters each having axially alined journal pins supported in alined holes of the arms and head, and means for operating the heaters.
