Improvements in Egg Beaters.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 that class of devices which are used for beating eggs
and other substances in connection with culinary purposes, and in which class of
devices, beater heads or agitators are operated to move in opposite directions,
when immersed in the material being treated, and the object and purpose of my
invention is to improve this class of devices so as to increase their efficiency, to
make them more reliable in their operation, and to simplify their construction.
My improvements upon this class of apparatus more particularly relate to the
construction and arrangement of the beater or agitator heads, and their con-
nection with other details of construction which will be more fully set forth in
the claims. While I have shown my improvements as used in connection with
well known parts of such machines, by my improved construction of them I
have added greatly to their efficiency, and usefulness and by which a complete
device is produced for beating eggs whipping cream, or aerating any liquid or
semi-liquid used in connection with culinary purposes.
Accompanying this specification to form a part of it there are two sheets of
drawings containing seven figures illustrating my invention with the same de-
signation of parts by letter reference used in all of them. Of these illustrations,
Figure 1, is a front elevation of my improved beater.
Figure 2, is a side elevation of the same, and
Figure 3, is a plan view of a blank from which the beater heads are shaped
by bending upwardly one of the side edges and one of the rounded corners of
the blades.
Figure 4, is a section taken on the line 1, r, of Figure 2, with the beater
heads or agitators shown in a top view, one above the other.
Figure 6, is a top view of one of the heads or agitators after its blades have
been bent upwardly upon one of their corresponding side edges and corners.
Figure 6, is a section taken on the line,, of Figure 5, and
Figure 7, is another section taken on the line 3, 3, of Figure 5.
The several parts of the device thus illustrated are designated by letter re-
ference and the function of the parts is described as follows. The letters H¹,
and H, designate the head or agitators, each of which has been cut or stamped
from thin sheet metal to give it the required shape. The head or agitator H',
has blades ha, ha, ha, ha, which are formed radially around a hub-form center h³,
there being between the blades a cut-away area ht. Each of the blades h³, has
one upturned side b', and a flat rounded corner m, with these up curves and
rounded corners formed upon corresponding sides of the blades.

page_text: The heads or agitators H, are made in the same manner as those formed upon
the head H, with the exception that the turned up side edges 63, and flat rounded
corners m³, are oppositely arranged as to the sides of the blades h³, when compared
with the location of the upturned sides and corners of the head or agitator H¹,
so that when the head or agitators H', and H³, are oppositely rotated the up-
turned side edges and corners of the blades will follow instead of preceding the
line of direction in which they are rotated.
To operate these blades the head or agitator H³, is mounted upon the lower
end of the shaft S, having a bearing J in the downward extension 13, of the
holder-handle E, and in the projection J of the holder-handle part, said shaft S
passing freely through the head or agitator H, and having formed thereon
immediately below the latter the collar C. The letter W, designates the motor-
wheel having the gears 9, upon one of its side faces, and provided with an
operating handle D, upon the other side near its rim. This motor-wheel W¹,
is mounted to turn on pintle-shaft P, projected from the side of the holder-
handle extension part E. The letter W, designates a spur-wheel or pinion which
is mounted upon the upper end of the shaft S, and whereat it is adapted to mesh
into the motor-wheel W, at the top of the latter, and as thus constructed when
the motor-wheel is actuated to turn it operates the pinion or spur-wheel W³, and
the shaft S, to rotate the head H.
The letter W³, designates another spur-wheel or pinion arranged to mesh into
the gears of the motor-wheel at the bottom of the latter, and this last named
spur-wheel or pinion is arranged to turn on the shaft S, by means of a journal
passage formed therein for the said shaft. The letters A designate a frame that
is made from a strip of sheet metal, and formed with the upcast arms A³, A³,
which integrally connect at the frame bottom where bent laterally with the
central hub-part h³, of the head or agitator H', and where thus laterally extended
at 23, there is formed a passage-way pt, for the shaft S. At their upper ends each
of these arms A³, connect with the under-side of the spur-wheel or pinion W³,
at diametrically opposite points. The letter 1.3, designates a pin passing laterally
through the shaft S, below its passage through the spur-wheel or pinion W
With the parts thus constructed and connected when the motor-wheel W¹, is
rotated by its handle it will turn both of the spur-wheels W and W³, in opposite
directions and also move the heads or agitators H, and H³, in opposite directions,
with the flat portions of the blades in each of the latter moving in advance of
the turned up portions. As thus constructed and arranged to operate a rapid
movement of the heads or agitators and their blades is produced, and when the
apparatus is immersed in the substance being treated a very prompt beating
and consequent aeration of it is accomplished. As thus made the device can be
very cheaply constructed.
To the construction of the frame F, and the manner of operating the spur-
wheels ar pinions, by means of the motor-wheel apart from my improved manner
of arranging and constructing them for actuating my improved method of forming
the heads or agitators and their blades I make no claim.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:
-
1. In an egg-beater, a head or agitator provided with blades each having a hori-
zontally flat side-edge and an upturned side-edge and corner substantially as
described and having open spaces between the blades, and arranged to be rotated
with the flat side edges of the blades in the advance of the movement substantially
as and for the purposes set forth.
2. In an egg-beater, heads or agitators made of sheet metal and each provided
with blades having an upturned side-edge and corner with open spaces between
the blades and with the upturned side edges and corners of the blades of each
head or agitator reversed as to location whereby the flat edge of the blades in

page_text: each of the heads ca agitators will move in advance of the turned up side edges
when the heads or agitators are oppositely rotated, substantially as and for the
purposes set forth.
3. In an egg-beater the combination with an upper and a lower head or agitator
each of which is provided with radially arranged blades, with each of the latter
having an upturned side-edge rounded corners and a flat side-edge, with a space
between the blades, substantially as described; of the shaft S, having the spur-
wheel W, mounted upon its upper end and arranged to pass freely through the
upper head or agitator, and connect with the lower head or agitator; a spur-
wheel W³, arranged to journal on said shaft; the frame A connecting said
spur-wheel W³, with the top of the upper head or agitator; and the motor-
wheel W, arranged to mesh into both of said spur-wheels and communicate
opposite rotation thereto, substantially as, and for the purposes set forth.
