Application June 27, 1947, Serial No. 757,623
2 Claims.
This invention relates to an egg beater, and more particularly to the type operable by upand-down motion of one hand.
A preferred embodiment of the invention is illustrated in the accompanying drawings.
Figure 1 is a vertical section through the new and improved egg beater.
Figure 2 is a fragmentary section similar to Figure 1, showing the egg beater in its lowermost position.
Figure 3 is a Vertical section through the device, taken at right angles to the showing of Figure 7.
Figure 4 is a horizontal section, taken along the line 44 of Figure 3.
Figure 5 and Figure 6 are horizontal details.
The device comprises a tubular vertical casing l provided with an upper knob portion II that is shaped to be grasped by the palm of the hand to operate the casing l0 up and down. Centrally mounted in the casing I0 is a stationary vertical frame l2, in which are mounted at the top and bottom thereof tWo horizontal pins I3 and I4. The shaft 13 carries a pulley l5, and the lower shaft [4 carries a similar pulley IS. A flexible endless cable I8 is trained over both of the pulleys l and H3. The tension of the cable I8 is such that rotation of one of the pulleys l5 and IE will serve to rotate the other. The lower pulley It has fixed thereto a vertical bevel gear 20, that is adapted to mesh with a horizonta1 bevel gear 2| to rotate a vertical shaft 22 secured to the horizontal bevel gear 2|. A series of curved blades 23 is attached to the shaft 22, and these blades 23 are adapted to beat the egg in a suitable container. The bottom of the shaft 22 has a balland-socket connection with a suction cup 24 that is attachable to the bottom of the container, so that the shaft 22 may rotate freely with respect to the suction cup 24. If desired, the shaft 22 may rotate about an inner fixed shaft, which inner fixed shaft will itself be fixedly secured to the suction cup 24.
The flexible cable 18 has a lateral offset tab extending therefrom, this tab 26 being either integral with the cable l8 or fixed thereto by means of a set screw 2'1. This tab 25 is adapted to be held in an appropriate horizontal slot 28 in the casing I0, so as to be movable therewith. It is obvious, therefore, that as the casing i0 is moved vertically up and down, the tab 26 will move therewith, and the cable l8 will be rotated about the pulleys l5 and IS. The stationary frame I2 is provided at its lower portion with a stop 30, the stop 30 being apertured to permit movement therethrough of the cable I8. This stop 30 is so positioned with respect to the frame l2 that the tab 26 will abut the upper surface of the stop 30 at the lowermost position of the casing III with respect to the frame 12. The upper portion of the frame l2 on the side opposite the stop 30 is provided with another stop 3|, this stop 3| being likewise lapertured to permit movement therethrough of the cable l8. Another tab 33, fixed laterally to the cable l8 by means of a set screw 34, is adapted to bear on the upper surface of the stop 3| when the casing I0 is in its uppermost position with respect to the frame 12.
The casing I0 is connected to the frame [2 by means of three telescoping members 40, 4|, and 42, that are slidable with respect to one another and with respect to the upper portion of the frame l2. The upper telescoping member has a button 43 that is embedded in the knob ll, so as to be fixed thereto. The upper portion of the frame l2 has a central recess 44 to contain the telescoping members 40, 4|, and 42 when they are in compacted position. A coil spring 45 bears against the bottom of the recess 44 and against the bottom of the telescoping member 40, to normally urge the telescoping members 40, 4|, and 42 into expanded position.
In the operation of the device, the knob H is depressed, telescoping the members 40, M, and 42 against the action of the coil spring 45. As the casing I0 goes down, the tab 26 attached to the cable l8 also goes down, and the cable I8 is given a counter-clockwise movement, as seen in Figures 1 and 2. The casing It continues its downward movement until the tab 26 abuts the upper surface of the stop 30. When the hand is released from the knob H, the coil spring 45 will restore the casing ID to its upmost position, and the upper limit of this position will be determined by the engagement of the tab 33 attached to the cable l8 as it abuts the upper surface of the upper stop 3|. During both the downward movement and the upward movement of the casing It, the shaft 22 will be rotated about a vertical axis, thereby actuating the beating blades 23.
I claim:
1. Actuating mechanism for an egg beater comprising a frame, two pulleys rotatably mounted on said frame in vertical alignment, an endless flexible belt drivably trained over said pulleys, a hollow handle substantially cylindrical in shape mounted over said frame, a telescoping spring biased means connecting said handle to said frame, a tab secured to said belt adapted to be engaged by said handle for vertical movement therewith, and gear means associated with one of said pulleys for driving the egg beater.
2. A mechanism for turning the shaft of an egg beater comprising a frame having a bearing for said shaft, a mitre gear secured on said shaft, a second mitre gear rotatably mounted on said frame, a pulley secured to said second mitre gear, a second pulley rotatably mounted on said shaft in vertical alignment over said first pulley, an endless flexible belt trained over .said" pulleys, a hollow handle having one end thereof closed; said handle enclosing one end of said frame, a compression spring axially mounted within said handle between the closed endstheneof: and=: said REFERENCES CITED The following references are of record in the filesof, this patent:
