PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Mixing Paint and other
like Substances.
I, JOHN HOLSALL HIND, of 64 Whittingham Street, Preston, in the County
of Lancaster, Paint Mill Engineer, do hereby declare the nature of this invention
to be as follows :-
This invention relates to Improvements in Machinery or Apparatus for Mixing
Paint and other like Substances. In carrying out my said invention I provide a
metal framing having two vertical sides or standards across the upper ends of
which is mounted in suitable bearings a horizontal shaft which may be rotated by
hand or power according to the size of the machine. The said shaft midway of
the standards carries two bevel wheels of different diameters which gear into other
bevel wheels on the upper ends of a pair of vertical shafts one of which works
inside the other the arrangement being such that the inner shaft is caused to rotate
at a quicker speed than the outer shaft. The said outer shaft is mounted in a
suitable bearing and at its lower end carries a cross head forming a pair of arms
from each of which depends a flat metal blade. The lower end of the inner shaft
also carries a cross head immediately underneath the first named cross head from
which also depend another pair of flat metal blades which work or rotate inside
the first pair. The four blades are however so placed on their cross heads as to
each move in or travel over a different concentric path and are preferably twisted
or curved so as to impart an upward movement or tendency to the material mixed
or operated upon. The paint or other substance is placed within a cylindrical pan
the bottom of which when in working position nearly touches the lower extremities
of the four mixing blades. Projecting from the lower outside edge of the pan are
four slotted lugs or ears which rest upon corresponding brackets (projecting from
the inner sides of the standards or side framing of the machine) to which the pan
is made fast by means of screw bolts and nuts the arrangement being such that
when it is desired to remove the pan from the rest of the apparatus the mixing
blades are first brought into line with each other whereupon-the nuts having been
unscrewed the pan is then capable of being readily slided off the brackets and so
dropped down clear of the blades. I preferably provide the bottom of the pan
with a slide or damper valve to allow of the mixed material being withdrawn
therefrom in small quantities without removing the pan bodily from the machine.

Improvements in Machinery or Apparatus for Mixing Paint and other

I, JOHN HOLBALL HIND, of 64, Whittingham Street, Preston, in the County
of Lancaster, Paint Mill Engineer, 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 :-

metal framing having two vertical sides or standards across the upper ends of
which is mounted in suitable bearings a horizontal shaft which may be rotated by

the standards carries two bevel wheels of different diameters which gear into other

also carries a cross head immediately underneath the first named cross head from
which also depend another pair of flat metal blades which work or rotate inside
the first pair. The four blades are however so placed on their cross heads as to
each move in or travel over a different concentric path and are preferably twisted

the bottom of which when in working position nearly touches the lower extremities

four slotted lugs or ears which rest upon corresponding brackets (projecting from
the inner sides of the standards or side framing of the machine) to which the pan
is made fast by means of screw bolts and nuts the arrangement being such that
when it is desired to remove the pan from the rest of the apparatus the mixing
blades are first brought into line with each other whereupon--the nuts having been
unscrewed the pan is then capable of being readily slided off the brackets and so
dropped down clear of the blades. I preferably provide the bottom of the pan
with a slide or damper valve to allow of the mixed material being withdrawn
therefrom in small quantities without removing the pan bodily from the
machine.
In the accompanying drawings,
Fig. 1 is a front elevation partly in section; and
Fig. 2 an end view of the improved machinery or apparatus hereinbefore
described;
Fig. 3 is a sectional plan view shewing the construction and arrangement of the
cylindrical pan within which the material to be mixed is placed-and attendant
parts; and
Figs. 4 and 5 are respectively side and end views shewing a method of applying
a lever or handle for the purpose of moving in or out a slide or damper valve at
the bottom of the said pan.
C
a a are the vertical standards or side framing bb bearings carrying the shaft
which may be rotated by belt driving pulleys d d or by a handle wheel e (such as
indicated by broken lines at Fig. 1). The shaft c has keyed or fastened upon it
the two bevel wheels fy which gear respectively into the bevel wheels hi. The
wheel is fastened upon the vertical shaft ; which works within a second (hollow)
or outer shaft k upon which is fastened the wheel i. As shewn at Fig. 1 the two
shafts and are arranged to rotate in opposite directions and the two wheels
and are of equal size whereas the wheel g is less than the wheel i-hence upon
the rotation of the shaft the inner shaft ; will be rotated at a quicker speed than
the outer shaft k as will be readily understood. The outer shaft k is carried in the
bearing and at its lower end carries the cross-head m from the two arms of
which the twisted blades n n depend. The inner shaft j carries another cross
head p carrying the inner twisted blades g q. The twisted form of the blades n ng
is designed to promote the lifting or raising of the material from the lower part of
the pan towards the upper part thereof during the mixing operation.

brackets indicated in broken lines at Figs. 2 and 3-to which the pan i

operating the slide or damper valve x the construction of which will be understood.
without any further description.
It will be obvious that the inner and outer sets of blades n n and 9 9 could be
readily arranged to rotate in the same direction and at varying or uniform
speeds. Also that the said blades if arranged to rotate in opposite directions
could be arranged to rotate at a uniform speed. But I find in practice that the
mixing operation is more effectively performed by causing the said blades to rotate
in opposite directions and more especially if at different speeds as hereinbefore
described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Machinery or apparatus for the purpose specified in which an inner and an
outer set of vertically arranged blades are caused to rotate in opposite directions
within the interior of a pan or receptacle containing the material to be mixed
substantially as hereinbefore described and shewn in the drawings.
2. The arrangement of slotted ears or lugs and the means for fastening and
disengaging the pan or receptacle in machinery or apparatus for the purpose specified
substantially as hereinbefore described and shewn in the drawings.
