COMPLETE SPECIFICATION.
A New or Improved Mixing Machine for Pastry-cooks and others.
I, WALTER GEARREN, of 9, Preston Street, Faversham, Kent, Gentleman, 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 a new or improved mixing machine, more particularly
intended for the use of pastry-cooks, and has for its object to provide a machine
by means of which the various ingredients, such as eggs, butter, sugar and the
like, can be thoroughly and quickly mixed together, while it is of simple
construction and capable of being readily taken to pieces for cleaning purposes.
In carrying my invention into practical effect, my improved machine consists of
a suitably shaped body or receptacle of block tin, zinc, copper or other suitable
material, designed to contain the ingredients required to be mixed, and which is
furnished with a lid sliding in grooves, while the lower part of the case, consists of
a hot water chamber for the purpose of keeping the ingredients at a suitable
temperature. The upper part forming the containing receptacle is hinged to the
lower part or hot water chamber, the bottom of the containing receptacle being
curved so as to come into contact with the water contained in the lower chamber.
I also provide a sliding frame designed to enter into and engage with slots or
recesses formed in the two opposite sides of the chamber or receptacle, which
sliding frame carries the beater, the latter being of suitable construction, according
to the materials being mixed.
The beater is carried in the frame in such a manner as to be free to revolve, the
rotation of same being effected by means of a spindle passing through the side of
the case, the squared end of which enters into or engages with a squared recess
formed in one end of the central spindle of the beater, the first mentioned spindle
being revolved by means of a hand-wheel or pulley through suitable gearing.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings, in which
Fig. 1 is a side elevation of my improved machine with the case in section,
Fig. 2 a front view of same (the hand wheel being shown in dotted lines) and
Fig. 3 a plan.
Fig. 4 shows the sliding frame detached and carrying a different form of beater
and Fig. 5 is an end view of same.
Figs. 6, 64, 7 and 74, are details of the beater and actuating spindle showing
method of connection.
Figs. 8 and 9 are front and side elevations of the machine mounted upon a
suitable stand where power is employed for driving same.
Like letters of reference indicate corresponding parts throughout the several
views.
My improved machine consists of the case or receptacle a hinged to the lower
part b designed to contain hot water and for which purpose it is provided with a
covered inlet and outlet tap v' (Figs. 8 & 9).
Within projecting parts y, y¹, of the case, grooves or slots are formed, into which
enter the enlarged upper ends of the sides f,, of the sliding frame, the said sides
being connected together by a cross bar f, while the lower end of each arm is
increased in size and furnished with a central hole or perforation within which the
ends of the spindle e of the beater are sprung so as to allow the said beater to be
revolved.

page_text: The means employed for effecting this is shown in detail in Fig. 6, 6, 7 and 7ª,
and consists in forming a squared slot q in the end of the beater spindle e while the
end of the spindle p passing through the case a carries a squared piece q'
corresponding to the recess y, into which it enters, while the lower part of the
enlarged end of this side of the frame is cut away as at q³ to allow of the squared
piece q sliding through same into the slot q.
In order to place the beater in the machine it is first sprung into the sliding
frame which is then passed into the case a from the top, the ends f', f', resting in
grooves formed in the projecting pieces y, y¹, where they are retained by the sliding
lids when closed, while the squared piece q¹ passes through the opening q² into the
recess 9 in the spindle e so that upon rotating the spindle p motion is communicated
to the beater, the spindle of which is supported upon the other side of the case by
a bearing block j. A pointer or indicator i may be employed which is attached to
the spindle for the purpose of showing when the squared piece q' is in the
required position for readily passing through the opening 9 into the slot 9.
The gearing employed for rotating the beater consists of the pinion to attached
to the end of spindle p and with which the two wheels w³, w³, mounted on axes p', ²,
engage or gear. The two wheels w¹, w², are furnished with arms c, c¹, united by
the connecting rod C which latter is actuated by crank shaft d supported or carried
by the two cross pieces t, t' of the frame or support t, the crank shaft & being
actuated by means of the hand-wheel furnished with handle h'.
The beaters may be of various forms according to the material to be mixed,
that shown in Fig. 1 being very suitable for mixing eggs and sugar, to which flour
or other ingredients can be afterwards added by hand as required. This beater
consists of the spindle e having radial arms n, each opposite pair being connected
by a curved cross arm n', thus each pair of arms and cross piece form a frame
between the sides of which short lengths of chain may be stretched or cross
bars having suitably shaped projections may be secured, or the two forms
may be utilized in one beater, each alternate frame carrying stretched chains r
and the intermediate ones being furnished with cross bars such as r¹. The
beater shown in Fig. 4 consists of a spindle e carrying two arms m, m³ the ends
of which are flattened out and shaped as shown in the drawing. This form of
beater is very suitable for mixing sugar, eggs and butter such as required for
making macaroons, Madeira cake and the like.
In order to fix the machine to the table, the two opposite sides of the case
are provided with bushed holes g, g' through which the long arm of the clamp
passes, the free end of same passing through or engaging with an eye or hook g³
fixed in the top of the bench or table upon which the machine is placed.
When the machine is to be driven by power it is mounted upon a suitable
stand as shown in Fig. 8 & 9 which stand is for preference made collapsible
so as to be capable of folding up and occupying but little space when not required
for use, while in this case the hand-wheel is dispensed with and replaced by
a fast and loose pulley p, p.
I do not restrict myself to the particular gearing deseribel and shown in
connection with this machine, on other forms may be employed, such as a single
wheel to be actuated by a handle and gearing with the pinion w or other forms
of gearing may be employed that may be found more suitable or convenient.
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 I
claim is -
1. The new or improved mixing machine, arranged, constructed, and operating
substantially as herein described and shown and for the purposes specified.
2. In a mixing machine such as above claimed, the improved method of fixing
the beater in position consisting of the sliding frame having enlarged ends f¹, f
entering slots in side projecting pieces y, y' in combination with the beating blocks j
substantially as herein described and shown in the drawings.

page_text: 3. In a mixing machine such as above claimed, the beater actuating mechanism
consisting of spindle e having squared recess 9, spindle p with squared piece q¹ in
combination with pinion w, gear wheels w¹, w², connecting rod C, crank shaft d'and
hand wheel h, substantially as herein described and shown in the accompanying
drawings.
