Improvements in Mayonnaise Mixers.
I, JENNIE DE WITT HARVEY, of Wilkes-Barre, in the County of Luzerne, and
State of Pennsylvania, United States of America, Gentlewoman, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:—
My invention relates to an improved culinary utensil designed for use in mixing
the ingredients of mayonnaise. Heretofore the mixing of mayonnaise has involved
considerable labour and skill inasmuch as the mixing of the ingredients has been
done entirely by hand. Constant beating of the yelks of the eggs had to be kept
up during the introduction of the oil, the latter being poured into the vessel from a
bottle. Greatcare had to be exercised in adding the oil, for if too much were put in or
the beating were not maintained sufficiently to thoroughly incorporate it with the
other ingredients the dressing would be spoiled. By my invention the whole
operation can be easily and expeditiously performed. The agitation requires but
little effort, danger of admitting too much oil is avoided, and the thorough
incorporation of that ingredient with the others is assured.
The invention will first be described in connection with the accompanying
drawings, and then pointed out in the claims :-
Figure 1 is a front elevation of my apparatus.
Fig. 2 is a vertical central section of the oil reservoir, showing the scale inside.
Fig. 3 is a broken detail view showing the manner of detachably securing the
cup holder to the beater-bracket.
Fig. 4 is a plan view, on a reduced scale, of the cup-holder and cup, showing the
means for steadying the latter, and also the lug by which the holder is removably
attached to the beater-bracket.
Referring to the drawings, A is the cup-holder, composed preferably of two
strips a of thin metal bent into U shape, placed at a right angle to each other, and
secured together at the botton, the upper ends of these strips being encircled by a
band a', also of thin metal. To this band is secured a bifurcated perforated lug a²,
for a purpose hereinafter stated.
B is the cup, of glass or other suitable material, steadied in the holder by means
of thumb-screws a passed through the band a' and bearing against the cup, as
clearly seen in Fig. 4.
C is a series of thin elastic wires, each having a return bend, and secured at
their upper ends in a disk D, having on its upper side a thimble-shaped projection d,
in whose upper end is formed a series of teeth d. The disk is suspended from a
support E, consisting of a flat bar of metal, by a stud e, on which latter the disk
is journalled.
F is a gear-wheel, journalled on a stud f fixed in support E, and provided with
a crank-handle G, the teeth f¹ of this wheel being in mesh with the teeth d' on
the disk.
The wires, the disk by which the wires are carried, and the described means for
imparting rotary motion to the disk constitute a beater old in the art, and therefore
no claim is made herein to the beater per se.
H is a standard, secured at its lower end, preferably by soldering, to support E;
and I is a metal ring secured to the upper end of said standard.
J is a cylindrical oil-reservoir, the lower portion of which is funnel-shaped, as
shown and provided with a stop-cock j. To the inner side of the reservoir is
secured edgewise a thin strip of metal K, whose free edge is stepped, as at 1, 2, 3 and 4,
to serve as a gauge for indicating when the required quantity of oil has been placed
D

page_text: in the reservoir. The reservoir is supported in the ring I by an outward turned
rim on the former engaging with the upper edge of the latter.
L is a two armed clamping bracket, to which support E is secured at its lower
end. Through the lower arm of the bracket is passed a thumb screw M for
securing the apparatus to a table N, the upper end of the screw carrying a bearing
plate m. The cup-holder is secured to the bracket by passing its bifurcated lug a³
over the lower arm and inserting a thumb screw o in the holes in the lug and arm.
The operation of my mayonnaise-mixer is very simple. The yelks of the eggs,
salt, mustard, and pepper are first placed in the cup and whipped by the beater,
the cock of the reservoir being then turned so as to let the oil (the required
quantity of which having been previously placed in the reservoir) pass into the
cup drop by drop, after which the beater is again put in motion by turning
wheel F. When the mass begins to thicken the oil may be allowed to flow in a
thin stream until all in the reservoir has run into the cup. The vinegar is then
added and thoroughly mixed with the other ingredients, when the dressing is ready
for use.
The cup-holder may then be disengaged from the bracket and the cup
taken out.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what I
claim is :-
1. A mayonnaise-mixer having a beater, a cup within which the beater-wires
operate, means for holding the cup removably in position, and an oil-reservoir
suspended above the cup, said reservoir being provided with means for regulating
the flow of the oil into the cup.
2. In a mayonnaise-mixer, the combination, with a beater provided with a
clamping-bracket, of a cup-holder removably secured to said bracket, a cup within
the holder, and an oil reservoir provided with a stop cock and arranged to discharge
its contents into the cup, for the purposes stated.
3. In a mayonnaise-mixer, the combination, with a beater provided with a
clamping-bracket, of a cup-holder removably secured to said bracket, a cup within
said holder, means for steadying the cup, and an oil-reservoir provided with a gauge
and means for regulating the outward flow of the oil, said reservoir being so
arranged as to discharge its contents into the cup, for the purposes set forth.
4. A mayonnaise-mixer comprising a rotary beater, a bracket for clamping the
beater to a table or like support, a cup holder removably secured to the bracket,
a cup within said holder, means for steadying the cup, a standard secured to the
beater and carrying a ring at its upper end, and an oil-reservoir carried by said
ring, said reservoir being provided with a gauge and a stop-cock, all substantially
as described.
5. The improvements in mayonnaise-mixers, substantially as and for the purposes
hereinbefore described, set forth, and illustrated in the drawings annexed.
Dated this 15th day of November 1893.
