COMPLETE SPECIFICATION.,
An Improved Domestic Combined Butter Churn and Egg Beater.,
;
We THOMAS SHIPMAN and SARAH ANN SHIPMAN, both of Penshurst, near-
Sydney, in the Colony of New South Wales 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 has been specially devised in order to produce a light and easily
manipulated mechanical churn specially adapted for household use and which
churn may be easily and quickly converted into an egg beater.
This invention will be more clearly understood by reference to the drawing
herewith in which
Figure 1. is a perspective view of the mechanical portion of the churn showing.
also in dotted lines the receptacle for the cream.
Figure 2 is a sectional elevation of the "dasher.
"
Figures 3 and 4 are partial section and plan of the cream vessel.
Figure 5 is an elevation showing the egg beater contrivance in a vessel for egg-
beating.
A are side frames having bearings A' for the driving spindle bearings A³ for
the crank shaft and bearings A for the rocking beam. In the bearings A¹ is the
spindle B carrying on its one end a crank handle B¹ and on its other end a toothed.
wheel B. This latter wheel gears into toothed pinion C2 on the end of the crank
shaft C which also carries a fly wheel C' and has on its crank a bearing on which.
takes the end of connecting rod D whose other end is jointed at D' to the rocking
beam E in bearings A³. To the other end of this rocking lever is bolted the
eye F of dasher rod F on the other end of which is the dasher formed of
perforated cross pieces F fastened together and carrying a nut into which the end
of said dasher rod F removably screws.
In operation the dasher rod F and dasher are inserted into a "billy" or can or
vessel G having a cover and containing the cream to be churned into butter. The
cover G' has preferably a funnel piece G2 thereon to prevent splashing and the
wasting of the cream and this cover being placed over the dasher rod F and.
the eye F passing through said funnel G2 the rod is bolted to the end E of the
rocking beam. Now it is only necessary to turn the crank handle B¹ and a very
rapid up and down motion is given to the dasher F and very quickly and.
effectively converts the cream in the vessel G into butter. After such conversion
the dasher rod F is unbolted from the end E2 of the rocking beam and the vessel G.
with the rod F removed and the butter washed and collected.
In order to hold the vessel from movement during churning clamp rods H₁ are.
screwed down on to the base I by means of winged nuts H' on bolts H adapted to.
slide for adjustment in slots I and these rods H' taking above a flange or the
bottom joint of the vessel G grip it tightly to the base.
In use as an egg beater the dasher is unscrewed from the rod F and screwed
thereto is the conical spiral spring J which rests upon the bottom K₁ of the
tumbler or vessel K so that the rapid up and down motion given to the dash rod F
(by turning the handle B¹) compresses and extends said conical spiral J and
effectively and quickly performs the operation of egg beating.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First. An improved domestic butter churn whose essential feature is the com-
bination and arrangement with the rocking beam and the other mechanical parts
of a dash rod such as F having upon the end thereof a dasher such as F or an
equivalent device for agitating and converting cream into butter substantially as
herein described and explained and as illustrated in the drawing.
Second. An improved domestic egg beater whose essential feature is the com-
bination and arrangement with the rocking beam and the other mechanical parts
of a dash rod such as F having upon the end thereof a conical spiral spring such
as J or an equivalent device for agitating and beating eggs substantially as herein
described and explained and as illustrated in the drawings.
