Specification of Letters Patent.

Patented Nov. 28, 1911.

Application filed January 18, 1911. Serial No. 603,236.

Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Beaters, of which the following is a specification.

My invention relates more particularly to devices for beating eggs, cream, dough, and the like, of the type involving a casing, a spring-pressed spiral rod carrying beater blades, and means on the casing engaglng with the spiral portion of the rod for rotating the latter in opposite directions when the casing is reciprocated on the rod; and my objects, generally stated, are to provide a simple construction of device of the character stated, which shall be economical of manufacture, highly useful for performing the work required of this class of devices, and which shall be so constructed as to permit of the ready interchanging of blades suitable for beating different mate rials.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a view in elevation of an eggbeater constructed in accordance with my invention. Fig. 2 is a plan view of the blank from which the handle of the beater is formed. Fig. 3 is a view in elevation of the spiral rod carrying the beater-blades. Fig. 4 is a perspective view of a follower carried on the inner end of the beater-rod and forming a stop for one end of the roddriving spring. Fig.5 is a broken view in sectional elevation of the upper end of the beater. Fig. 6 is a section taken at the line 6 on Fig. and viewed in the direction of the arrow. Fig. 7 is an enlarged section taken at the line 7 on Fig. 1 and viewed in the direction of the arrow. Figs. 8 and 9 are perspective views of the beater-blades employed. Fig. 10 a sectiorf taken at the irregular line 10 on Fig. 7 and viewed in the direction of the arrow. Fig. 11 is a broken view in elevation and partly sectional, of the device of the preceding figures, showing a blade attached thereto, especially adapted for beating cream. Fig. 12 is an edge view, in elevation, of the lower end of the beater-rod. Fig. 13 is an end view of the device of Fig. 11. Fig. 14: is a face view of a desirable construction of blade for beating batter, and Fig. 15 an edge view of the blade of Fig. 14.

Referring particularly to Figs. 1 to 10 inclusive, the handle of the device which is in i the form of a casing is illustrated at 11 and is preferably formed from a sheet-metal blank 12 which is of substantially rectangular shape and is provided at its opposite ends with circular extensions 13 each formed with a projection 14. The handle is formed by bending the blank 12 to tubular form in which its free edges overlap each other as represented in Fig. 6. The extensions 13 are then bent over to cover the open ends of the tube to form caps therefor, and the projections 14: bent to overlap the end-portions of the tube as clearly represented in Fig. 1, for holding the tube in shape. If desired, the projections 14 and overlapping edges of the tube may be soldered together; and a wooden socket represented at 11 may be applied to the upper end of the casing 11.

The rod to which the beater-blades hereinafter referred to are attached is represented at 15 and is formed with a spiral section 16 intermediate its ends, this rod being preferably formed from a strip of metal spirally twisted to produce the section 16. The opposite ends of the rod 15 are preferably straight as represented at 17 and 18 respectively, the upper section 17 of the rod being provided at its lower end with a shoulder 19 and the lower section 18 containing in its upper end notches 20.

The rod 15 extends at its spiral section 16 through a rectangular slot 21 in the lower cap 13 and is normally held in the extended position illustrated in Figs. 1 and 5, in which barbs 22 cut from the spiral section 16 bear against the upper surface of the lower cap, by a coiled spring 23 in the casing 11, the spring hearing at one end. against the under side of the upper cap 13 and at its opposite end against a cup-shaped follower. 24 carried by the section 17 of the rod and seated upon the shoulder 19.

The beater-blades, of a form especially adapted for beating eggs, are represented at 25 and 26 and are preferably in the form of spring-metal split bands, the band 25 containing two openings 27 adjacent to its free end-portions, and a single opening 27 approximately diametrically opposed thereto, these openings which are elongated extending transversely of the periphery of the band. The band 26 contains

openings

28 and 29 located in the same relative positions as the

openings

27 and 27, the openings in the

bands

25 and 26 extending at rightangles to each other.

The

bands

25 and 26 are secured to the rod 15 by first inserting one band into the other to cause them to extend at rightdercut walls of the notches 20, whereby the bands are firmly looked upon the rod 15 as illustrated in Figs. 7 and 10.

In operation, downward pressure on the handle 11 when the lower end of the rod 15 bears against the bottom of the receptacle containing the material to be whipped, causes the handle to move down on this rod against the resistance of the spring 23, with the result of rotating the rod and the blades in one direction by reason of the engagement of the spiral with the walls of the opening 21. As soon as the operator relieves the pressure on the handle, the recoil of the spring causes the handle to rise, with the result of turning the rod and beater-blades in the opposite direction. It will thus be .understood that by alternately pressing down upon the handle 11, thereby rotating the rod and the blades and compressing the spring, and relieving the pressure on the handle, thus permitting the spring to recoil and raise the handle, the rod and blades will. be caused to rotate first in one direction and then in another, thereby thoroughly agitating the material to be whipped.

Referring to Figs. 11, 12 and 13, the construction therein shown is the same as that illustrated in the preceding figures, excepting in the following particulars: The rod 15 contains, in addition to the notches 20, a notch 30 in a flat side thereof, and instead of providing barbs 22 on the rod 14: for limiting the outward movement of this rod in the casing 11, a tube 31 is provided for this purpose, which surrounds the upper end of the spiral section 16 of the rod and is located between the lower one of the caps 13 and the follower 24. The rod 15 in this construction is illustrated as equipped with a beatenblade 32 in the form of a disk having strap-sections 33 provided therein, these strap-sections and the adjacent portions of the disk 32 being deflected in opposite directions as represented in Figs. 11 and 13 to permit of the insertion through these straps of the lowerend of the rod 15, the upper one of the straps 33, when the disk 32 is posi tioned on the rod 15 for use illustrated in Fig. 11, springing into the notch 30 for releasably holding this disk in place on the rod. The disk 32 is perforated, preferably, by providing openings, such as those shown at 3 1, in Fig. 11, with wings 35 at the vertical edges of these openings.

In Figs. 14 and 15 I have illustrated a desirable construction of blade for beating batter. releasably secured to the rod 15, and which is represented at 36, is in the form of a perforated disk provided with strap-sections cut from the metal of the disk and bent to extend out of the plane of the latter. The disk 36 is adapted to be applied to the rod 15 by inserting the lower end of this rod through the strap-sections 37 the upper one of these strap-sections springing into the notch 30 when this disk is positioned on the rod for use.

It will be noted from the foregoing that the different forms of beater-blades illustrated are interchangeable, and that they may be readily applied to and removed from the rod 15 as substitution of one for the other is desired. Thus, a heater constructed in accordance with my invention may be supplied to the user with a set of blades suitable for beating different materials, and the application of any one of the blades to the rod 15 may be quickly and easily effected.

It will be manifest that a heater constructed in accordance with my invention may be furnished to the user at relatively low cost, as the construction is very simple. Furthermore, and as another item in the matter of the cost of manufacture, it will be observed that the parts of the construction do not require soldering.

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