MAURICE WICKSTROM, OF FITCHBURG, MASSACHUSETTS.

EGG-BEATER.

Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed April 10, 1914. Serial N o. 831,010.

To all whom it may concern Be it known that I, MAURICE WIcKsTRoM, a citizen of the United States, residing at Fitchburg, in the county of l/Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Egg- Beaters, of which the following is a speciiication.

My invention relates to culinary articles, and more particularly to egg beaters.

My object is to provide a device of this character which can not only be supported with one hand and operated with the other, as is usual with egg beaters, but which can also, when desired, be secured to a table or other support and operated with one hand, leaving the other hand free.

Another object is to provide the device, when used in the latter' manner, with means adapting the beater proper to readily adjust itself to vessels having bottoms of different thicknesses.

A further object is to provide means, when the device is used in the latter manner, for receiving and firmly holding vessels of different heights for containing the eggs.

A still further object is to provide a device of great durability, and one which, when not in use, can be packed or stored in a very small space.

Other objects will appear in the subjoined description.

The invention consists in certain novel parts and combinations as will be hereinafter described and claimed.

Referring to the accompanying drawings ;-Figure 1 is a perspective view of my device when used as a stationary beater. Fig. 2 is a side elevation showing it used as a. portable beater. Fig. 3 shows the spring-pressed plate for holding the egg container when the device is used as a stationary beater. end of the shaft of the beater, the enlarged extension of the shaft being shown in section; and, Fig. 5 is a sectional view of the shank of the auxiliary beater, taken on the line 5-5 of Fig. 2, looking in the direction of the arrow, the shaft extension which engages this shank being shown in dotted lines.

The numeral 1 indicates the frame of my' beater which is provided at one end with the usual clamping devices for securing the same to a table or other suitable support; and at its other end the frame is provided Fig. 4 is a view of the upper' with the right-angled extension 2, which terminates in a bifurcated end 3 having the vertical bores 4: adapted to receive the shaft 5. Rigidly secured to the lower end of this shaft is the head of the beater proper, which may be formed in any desired manner. It is here shown as formed of a plurality of twisted wings 6 bent upwardly and turned slightly outward at their upper ends.

The shaft 5 is provided at its upper end with a threaded portion 5ZL (Fig. 4) adapted to be received into the cooperating threaded aperture 7a of the enlarged shaft extension 7 rIhe thin nut 8 is also received onto the threaded portion 5a of the shaft 5. This nut serves as a jam-nut for the enlarged extensionv 7 to hold the same in fixed engagement with the shaft 5.

The extension 7 has a portion 9 at its lower end, roughened by milling or otherwise, and at its upper end has a slot 10.

Opposite the upper part of the clamping portion of the frame, the V-shaped operating lever 11 is pivoted at its apex to said frame. The shorter end 11a of this lever has a twist and extends upwardly and outwardly to receive the handle 12, while the other end extends upwardly and inwardly to a point above the upper end of the frame opposite the roughened portion 9 of the shaft extension 7 At the top of the frame and on the opposite side thereof from the operating lever 11, the thin strap spring 13 is secured at one end to the frame by the thumb screw 14. To the other end of this spring is suitably secured one end of the fiexible band 15, which band is passed around the roughened portion 9 of the enlarged upper extension 7 of the shaft 5, with the inner end of said band connected by means of a double hook 16 to the upper end of the arm 11b ofthe operating lever, said arm being vprovided with a plurality of holes 11c adapted to be engaged by said hook.

The pin 17 limits the inward movement of the operating lever 11b when under the control of the spring 13.

In order to hold the vessel, containing the eggs to be beaten, perfectly .steady during the beating operation, I provide for my device as a part thereof, the pressure plate 18, which is firmly pressed upon the top pf the vessel by the spring 19, which sprlng is loosely received upon the shaft 5 underneath the bifurcated end 3 of the frame. The

plate 18 has a slot 18a opening at one side of the plate and adapting the plate to be passed laterally upon the shaft 5; and the spring 19 has a hook 19a at its lower end which engages the other side of the plate when in operative position, and keeps the plate fromy moving laterally od the shaft. The spring permits the plate to be adjusted up and down to suit vessels of different heights. lVhen the flexible band 15 is disengaged from the enlarged extension 7 of the shaft 5, said shaft 5 may be freely moved up and down in the bifurcated end 3 of the frame to permit the insertion or removal of a vessel containing eggs, cream or other material that has been beaten or that is to be beaten.

The handle 12 of the beater' is provided at its inner end with a slot 12f adapted to snugly receive the end 11a of the operating lever. To insure that the handle shall always reliably engage the lever, and also to prevent it from having lateral movement on the section 11a, it is provided at its inner end with the ring 12b.

vl'Vhen it is desired to pack the beater for shipping or transportation, the handle 12 is moved rearwardly out of engagement with the section 11a of the lever; the spring 13 is disconnected by means of the thumb screw 14 and the double hook 16; the pressure plate 18 is easily disengaged from the shaft 5 when the egg-containing receptacle is removed; and the enlarged shaft extension 7 and the lock nut 8 may be quickly unscrewed from the top of the shaft 5; hence the entire device can bey easily disassembled and packed in a very small space.

Fig. 2 shows the device when used as an ordinary egg beater is used, that is, held in position with one hand and operated with the other. When used in this way the device is inverted and is provided with a plain rod 20 which serves as a leg for supporting it in operative position. yThis rod is received at its upper end into a bore 21 in the frame.

vThe auxiliary beater head 22 is secured in the slot 10 of the shaft extension 7. The

vWhen the device is to be used to any great f extent in its inverted position, the shaft 5 may be removed and the short auxiliary v shaft 5 7 substituted in its place as illustrated in Fig. 2. This change however is not absolutely necessary, but as it can be made with comparative ease, is sometimes resorted to for convenience.

The auxiliary shaft 5x is provided with atight fitting washer 24 to prevent the beater from falling from the frame in case the flexible band 15 should accidentally become disengaged from the extension shaft 7.

lTo operate my device as a stationary beater for beating eggs, whipping cream, etc., the frame is clamped to a suitable support, as illustrated in Fig. 1; the shaft 5 is elevated, and the receptacle containing the eggs or other material to be beaten is placed underneath it; the shaft is then lowered to bring the head of the beater' preferably to the bottom of the vessel; the flexible band 15 is then brought around the roughened part 9 of the extension shaft 7 and secured at its inner end tothe upper end of the operating lever; the pressure plate 18 may then be placed in position on top of the receptacle if desired, though the device works thoroughly well without this plate ;-and then the handle 12 is moved up and down, which, owing to the small diameter of the shaft extension 7, gives a very rapid backfand forth whirl to the beater. f

The spring 13 is comparatively long, so also is the arm 11b of the beater, which causes a comparatively slight movement of the handle to impart a long sweep t0 the upper end of the arm 11b.

The fact that the portion of the shaft eX- tension 7, which is engaged by the band 15, is thoroughly roughened, causes the band to take a firm frictional grasp upon it notwithstanding the comparative smallness of its diameter.

When the device is used in itsV inverted position as illustrated in Fig. 2, the supporting leg 20 can stand inside the receptacle containing the eggs, if desired, and when so used can be cleaned with extreme ease, but if the receptacle have compara# tively vertical walls, the leg 2O can stand outside the same, which is a feature, so far as I am aware, that is not possessed by any other portable egg beater.

When it is desired that the beater shaft shall work in a position somewhat above or below its ordinary position, the band 15 is correspondingly raised or lowered by slightly loosening the thumb screw 14, and giving a proper rotation of the spring 13 on said screw to raise or lower the free end of the spring as desired, and then by changing the double hook 16 to the proper one of the openings 11c at the upper end of the operating lever.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. n a device of the character described, a frame having its parts disposed in a plane and provided with a lateral supporting arm; a rotary shaft passing through said arm and disposed in the same plane therewith; a beater carried by said shaft; an

operating lever pivoted to one side of the frame below said supporting arm and adapted to move back and forth in a plane parallel with the frame; a spring at the other side of the frame removably secured at one of its ends to the frame with its other end extending out laterallyr from the frame and operating lever; and a flexible connection extending from the free end of the spring around and in engagement with the rotary shaft above the supporting arm, and connected at its other end to the operating lever.

2. In a device of the character described, a frame having clamping means at one end and an angular extension at the other; a beater shaft rotatably supportedin said extension, and having one of its ends ex tending beyond the frame, said shaft and the dierent parts of said frame all lying in the same plane and each end of said shaft being provided with means for engaging a beater head; a removable leg for supporting the beater when used in inverted position; an operating lever pivoted between its ends to one side of the frame below said angular extension, and a coperating spring extending away from the frame at the other side; and a flexible connection extending from the free end of the spring around and in engagement with the projecting end of said beater shaft, and connected at its other end to the free end of the operating lever.

3. In a device of the character described, a frame having clamping means at its lower end and an angular extension at its upper' end; a beater shaft rotatably mounted in said upper extension to move up and down therein and extending downwardly therefrom and provided at its lower end with a beater head adapted to be received into a suitable receptacle; a pressure plate adapted to rest on top of the receptacle and provided with a slot extending inwardly from one of its sides to approximately its center and of a width to snugly receive said shaft; a compression spring surrounding said shaft at the under side of said angular extension and adapted to bear downwardly upon said plate, said spring being provided at its lower end with means for holding the plate against lateral movement off the shaft; and means on the frame for imparting rotation to the shaft.

t. In a device of the character described, a frame having clamping means at its lower end and an angular extension at its upper end said parts being disposed in a plane; a beater shaft mounted in said angular extension and disposed in the same plane therewith and provided at its upper end with an extension of increased diameter, said latter part projecting above the frame and having the lower part of its periphery roughened; a V-shaped operating lever pivoted at its apex to one side of the frame below said angular extension and adapted to move back and forth in a plane parallel with the frame and having a handle at one end and its other end extending upwardly above the top of the frame to approximately the level of the roughened portion of said shaft extension; a strap spring secured at one end to the top of the frame at the opposite side thereof from said lever and extending out laterally therefrom and bent to elevate its free end to approximately the level of the free end of the operating leverand the roughened portion of the shaft extension; and a flexible band extending from the free end of the spring around the rough ened portion of the shaft extension, in frictional engagement therewith, to the free end of the operating lever.

In testimony whereof I affix my signature in presence of two witnesses.
