Improvements in and relating to Liquid Switchers or Mixers.
I, WILLIAM WADDELL of Russell Street, Wishaw, Lanarkshire, Machine Maker, do
hereby declare the nature of my invention to be as follows :-
This Invention has reference to and comprises improved fittings connected with
switchers or mixers, for eggs, milk, or other liquids, of the class which has revolving
or agitating bows mounted on axes passing through or, within each other, within the
switching vessel, the gearing being attached to the vessel outside. The improved
fittings enable the switcher to be more efficiently secured in its bearings within the
vessel, and removed therefrom, than has been the case heretofore, and specially
applicable to the switching or mixing apparatus and gearing for which the present
Applicant obtained Letters Patent No. 13,178 Nov. 13 1885.
The improvements consist substantially in fitting in bush bearings in the sides of
the vessel the end journals of the axes of the revolving switch bows which may he
four in number mounted in eyes divided round each axis in the same line, the bushes
being mounted preferably at the bottom of shallow grooves the depth of the journals
formed vertically in the sides of the vessel just over the semi-spherical bottom of the
vessel within which the switching bows rotate, and in line with the coupling or
couplings of the driving gearing of the spindle taking into corresponding couplings
on one end of the axes of the switch bows, so that the opposite end journal of the
axis or inner axle may be raised up out of its bush in the groove as hereinafter
described, and so enable the coupling of the switch spindles to be drawn out of the
driving coupling of the outer spindles and the whole removed from the vessel. A
main or important improvement consists in mounting on the end of the axis opposite
to that of the couplings, a loose spring blade or rod within the vertical groove over
the bush with a catch which takes into a notch in the said groove of the vessel, and
holds this end of the spindles and switches down in the bearing bush, with a lateral
spring catch on top, which takes into a retaining catch above the holding down catch
for retaining the spring blade within the groove, and up out of the way of the
revolving switch bows. This upper lateral retaining catch also forms a handle for
lifting this end of the spindle out of its bush, and to assist the better effecting of this
the front end of this lateral spring arm is bent down with a hook end, which when the
spring catches are taken out of their notches is hooked on to one of the outer bows, so
as to enable the spring retaining catch blade to form a handle for lifting the whole
out of their couplings and bushes in the vessel as before described, and also prevent
the spring blade which secures the spindles in their bushes from swivelling down into
the vessel in the act of inserting or removing the switchers.
A further improvement consists in making the semi-circular switch bows of square
drawn wire, in place of round wire, which has the effect of cutting and breaking the
liquid more perfectly than the round wire heretofore employed.

Improvements in and relating to Liquid Switchers or Mixers.
I WILLIAM WADDELL of Russell Street Wishaw Lanarkshire Machine Maker 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 reference to and comprises improved fittings connected with
switchers or mixers for eggs milk or other liquids of the class which have revolving
bows mounted on axis passing through or within each other within the switching
vessel the gearing being attached to the outside of the vessel. The improved
fittings enable the switcher to be more effeciently secured within its bearings within
the vessel and removed therefrom than has hitherto been the case and specially
applicable to the switching or mixing apparatus and gearing for which the present
applicant obtained Letters Patent No. 13178 Nov. 13th 1885. The improvment
consists substantially in fitting in bush bearings in the sides of the vessell the end
journals of the axis of the revolving switch bows which may be four in number
mounted in eyes diveded round each axis in the same line the bushes being mounted
preferably at the bottom of shallow grooves the depth of the journals formed vertically
in sides of the vessel just over the semi sperical bottom of the vessel within which
the switch bows rotate and in line with the couplings of the driving gearing of the
spindle which couplings take into corresponding couplings on the end of the axis of
the switch bows so that the opposite end journals of the axis or inner axle may be
raised up out of of its bush in the groove as herinafter described and so enable the
coupling of the switch spindles to be drawn out of the driving couplings and the whole
removed from the vessel. A main or important improvment consists in mounting on
the ends of the axis opposite to that of the couplings a loose spring blade or rod
within the vertical groove over the bush with a catch which takes into a notch in the
said groove in the vessel and holds this end of the spindles and switchers down in the
bearing bush with a lateral spring catch on top which takes into a retaining catch
above the holding down catch for retaining the spring blade within the groove and
up out of the way of the revolving switch bows the upper part of spring blade or rod
forms a handle for lifting this end of the spindle out of its bush, and to assist the
better effecting of this said blade is bent down with a hook end which when the spring
catches are taken out of their notches is booked on to one of the outer bows so as to
enable the spring catch blade to form a handle for lifting the whole out of their
couplings and bushes in the vessel as before described and also prevent the spring
blade or rod which secures the spindles in their bushes from swivelling down into the
vessel in the act of inserting or removing the switchers.
In order that my invention may be more readily understood 1 now proceed to
describe the drawings herunto annexed. Fig. 1 is vertical section drawn from the
line A. B on Fig. 2. Fig. 2 is a plan and Fig. 2 is a detached portion of the spring
blade or handle with hook to attach to the outer hoop. Fig. 3 is a vertical section
taken on the line A B of Fig. 2 as Fig. 1 shewing the spring handle detached from
groove and partly removed from vessel. Fig. 4 is a side elevation.
According to my improvment I secure bush bearings D and E in the sides of the
vessel F at the bottom of the grooves K & L which are formed vertically in the sides
of the said vessell in which journals or bushes the axis of the revolving switch
bows G and g¹ rotate the said bush bearings D and E and the corresponding axis of
the revolving blades being in line with the couplings of the driving gearing n the
couplings of the driving gearing take into the couplings m of the revolving switch
bows so that the opposite end g of the axis of the switch bows may be lifted up out of
its bushes in the groove K as shewn on Figs. 1 and 3 and as hereinafter described and
so enables the couplings of the switch spindles h to be drawn out of the driving
couplings m and the whole removed from the vessel. An important improvment
consists in mounting a blade or rod O on the end of the axis g within the groove K and

page_text: over the bush D with a catch P which takes into the notch R in the said groove K of
the vessel and holds this end of the spindle or axis G of the switcher down in its
bearing bush with a lateral catch S on top which fits into a retaining catch t at the
top of the groove and which retains the spring blade o and within the groove and
up out of the way of the revolving switch bows I. The said blade or rod O forms a
handle for lifting this end of the spindle out of its bush and to assist the better
effecting of this the front end of blade o is bent down and a hook formed in point
more particularly shewn on Fig. 2 which when the spring catches P and S are taken
out of their notches are hooked to the outer bow of the switcher and thus forms a
handle for lifting the whole out of its bearings and couplings as shewn on Fig. 3
partly raised from the vessell F as before described and also prevents the spring blade
or handle from swivelling down into the vessell when in the act of inserting or
removing from the vessell.
Having now particularly described the nature of my invention and in what manner
the same is to be performed I now declare what I claim to be
The general arrangments and combination of parts constituting the improved
fittings of a whisk switcher or mixer by which the switcher is held in its bearings
more securely than heretofore and more easily removed therefrom all substantially as
herein before set forth and as shewn on the annexed drawings.
