PROVISIONAL SPECIFICATION.
Improvements in Mixing, Beating, and Agitating Apparatus.
WILLIAM HOLBROOK Plumber and Gas Engineer residing at No. 2 High Road
Upper Clapton London N.E. do hereby declare the nature of this invention to be
as follows:
My invention consists of a machine of forms specified below.
It is intended for the turning about and subdivision of many articles of a liquid
or semiliquid character such as the manufacture of butter from milk or cream the
beating up of eggs &c. or it can be used for the mixing of articles that have not a
special affinity for each other such as the causing of conglomeration between liquid
or semi liquid drugs. & the different vehicles used in the manufacture of
ointments &c.
This improvement as described above or divider works on the material which it
breaks up with a backward and forward motion and can be made of any convenient
material, metal, wood, bone ivory, xylonite or their several imitations and of any
convenient form but all working on the same principle e.g.
1st form. Like an Archimedean screw propeller or boomerang.
2nd. Like the vanes of a windmill open at the ends of the flanges.
3rd. Like the vanes of a windmill closed at the ends of the flanges.
4th. Like the paddle of a steamer.
For the sake of convenience I may attach my invention to an Archimedean
Screw handle.

COMPLETE SPECIFICATION.
Improvements in Mixing, Beating, and Agitating Apparatus.
I WILLIAM HOLBROOK of 2 High Road Upper Clapton London in the County
of Middlesex Manufacturer 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 :-
This invention relates to disintegrators instruments or appliances such as are
domestically known as egg beaters that is disintegrators or apparatus for whipping.
up or beating the fluid part of eggs or other fluids in cooking or other operations
and my present invention is designed to produce a simple but very effective
apparatus for this purpose which can be easily and expeditiously used and cleaned
and for domestic (i.e. cooking) purposes can be sold at a low price so as to bring it
within the reach of the many.
t:
This novel apparatus I have designated and introduced to the trade as the
Diatrope" by which name I wish it to be generally known.
My invention consists in a machine of forms specified below.
It is intended for the disintegration and subdivision of many materials of a liquid
or semi-liquid character such as the manufacture of butter from milk or cream the
beating up of eggs etcetera or it can be used for the mixing of articles that have
not a special affinity for each other such as the causing of conglomeration between
liquid or semi liquid drugs and the different materials used in the manufacture of
ointments.
This disintegrator or divider works on the material which it breaks up with a
backward and forward instion and can be made of any suitable material or materials

page_text: such as wood metal vulcanite glass china or the several imitations of these materials
and may be made of any convenient form and size.
The beater" part of the apparatus may be of any of the following forms:-
1st. Like an Archimedean screw propeller.
2nd. Like the vanes of a windmill open at the ends of the flanges.
3rd. Like the vanes of a windmill closed at the ends of the flanges and
4th. Like the paddle of a steamer.
"
Any one of these "beaters is attached to a backward and forward revolving
device for instance the handle may advantageously be a hollow female screw on
Archimedean lines or it may differ from those screws known as Archimedean screws
as the screw may be the handle itself.
I attach a button or plug of a shape conforming to the thread of the screw to the
end of a rod and this button or plug runs up and down inside the handle following
the threads of the screw-a spiral spring is arranged and combined inside the
screw handle and the said button or plug is firmly attached to the beater spindle
which it thereby quickly revolves as it runs up and down the said spring forcing
the plug down the handle to the bottom-the operation being hereinafter
explained.
And in order that my present invention may be fully understood and readily
carried into practice I will proceed to further describe same with reference to the
accompanying sheet of drawings.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view in elevation (partly in section) showing an egg beater
made in accordance with my present invention.
Figure 2 is a cross sectional plan on line 1-1 Figure 1.
Figure 3 is an underside plan.
Figure 4 shows a side view of an alternative beating device.
a is the beating device (having flaps or striking surfaces a' thereon) advan-
tageously stamped out of tin plate for economy.
This benter part a is firmly soldered or otherwise fixed to the spindle 6 the lower
end of which projects below a and forms a point on which the benter revolves.
The upper end of spindle is rigidly attached to the nut c the edges of which fit
into the internal thread of the hollow female screw handle d advantageously made
of thin sheet brass or other thin sheet metal.
e is a spiral spring of sufficient strength to keep the nut c pressed down to the
bottom of the hollow handle d.
fis removable cap.
The operation is as follows:-
The beater a is placed in the material to be beaten and the operator grasps
the handled and presses same downwards quickly so that the nut e is caused to
travel up the internal thread of d to the top or thereabouts and thus quickly
revolves the nut on the spindle band consequently the beater a; the downward
pressure is now released whereupon the now compressed springe extends itself
quickly forcing the nut back to the other end again and so on-thus alternately
giving a series of quick revolutions to a both backwards and forwards.
Figure 4 shows another beating device which may be mounted and actuated
similarly to .
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
1. In egy beaters or other disintegrators for fluids--the combination of the
beating device a a' with a hollow screw handle such as d and a nut
and spring
operating therein substantially in the manner and for the purposes hereinbefore
described and illustrated in the drawings hereunt annexel.
2. In egg heaters or other disintegrator-for flu - claim a beating or agitating

page_text: device such as illustrated in either Figure 3 or 4 rotated backwards and forwards
alternately by and in combination and acting in conjunction with a nut on the
end of the beater spindle and a hollow internally screw threaded handle in which
the said nut operates substantially in the manner and for the purposes hereinbefore
set forth.
