3 Claims. _ (01. 259-107)
This invention relates to an improved paint
mixer in the form of an attachment accessory
particularly apt and practicable for use in con
junction with paint‘marketing tins, jars and
equivalent containers.
Brie?y described, and considering the several
embodiments in a generic sense, the preferred
concept is characterized‘by a rotary dasher or
-agitator unit, this being suspended from and
mounted for rotation on especially designed
adapter and suspension means in such a Way as
to permit the stirring result to be obtained with or

glass container.

A» generalzperusal of the drawings will reveal
a generic trend of thought in carrying-the dif
ferent embodiments of the invention into e?ect.
In fact, it seems appropriate to call attention 16
here to the rotary agitatorunit, since this is com
mon throughout the views. This is true whether
without the stock lid or closure for the container.
One feature of the invention is predicated on
the adoption and use of a practical rotary agitator

of the invention disclosed, as casual inspection 15

commodate the telescoping retention annulus 23
on the disk-like lid or cover 24.
With the cover in _
place, a nail or punch is driven centrally there
through to provide an opening for the shaft ll.
Then on diametrically opposite sides of this addi
tion'al holes. are punctured to accommodate at
taching screws ll‘which serve to hold in place
the U-shaped adapter bracket or ?xture II. The
bight‘ portion of this. is apertured and its aperture
10 is aligned with that in the can top so that the
parts properly coordinate'to facilitate rotation
and to allow vertical adjustment. In this ar
rangement the bight portion also functions as a
rest for the sleeve I! and thus the parts co
15 operate in providing a suitable rotary hearing as
sembly. It is evident that the bracket is placed
in position first after which the can top 24 is
removed. Then with the hand crank detached
from the shaft l I the latter part is shoved through
20 the opening in the can top and the guide open
ing and the bracket 26. By replacing the sleeve
I9 the assembly is set and ready to ‘use in stirring
the contents of the can.
.
‘
It is also evident that the L-shaped blades I2
25 are disposed in overlapping relationship or may
be spread apart and arranged in di?erent posi
tions ‘depending on the density of the liquid to be
stirred. For instance, with the blades as illus
tratedin Figure 8 the shank portions are disposed
30 in diverging relation which provides a “boring
down and in” action, assuring effective agitation
guide is here in the form of a tubular bearing
39 held in place by washers 40 and 4|, there be
ing a bushing 42 (see Figure 5) to provide for
stabilized rotation of the shaft. This multiple
part guide is suitably supported between a pair 6
of spaced parallel angle irons 43. These are
duplicates and rest on the ledge or lip of the can
44 in the manner shown. As brought out to ad
vantage in Figures 2 and 3, thevertical ?anges
of the respective angle irons are bolted together
as indicated at 45, there being spacing sleeves
48 surrounding the bolts and interposed between
the ?anges to facilitate assembly and mainte
nance of parts. The two clamping units in this
arrangement are similar in many respects to 16
the clamping devices 32 seen in Figure 9. In this
arrangement, the clamping devices are distin
guished by the numerals 41. As shown to ad
vantage in Figure 4, the clip 48 has its end por
tions 49 and 50 suitably shaped to provide de
tents or retention elements engagea'ole either
with the interior or exterior of the can. Also
the clip is here provided with a socket 5| to ac
commodate the headed ends of the studs or bolts
52, said bolt being provided with a thumb nut
53 and associated washer 54. The function of
the part Si is that of a key, since it fits between
the vetical ?anges of the angle irons and pre
vents rotation of the clip. Thus, the two devices
41 can be slid in either direction, reversed or de
of paint which may be thick at the bottom of

unit “as in the nature of a truss-style adapter

35 with the shank portions in longitudinal align - devices utilized to take care of the average job
ment.
In fact, one will learn from experience
just how best to adjust the blades according to
the job in hand.
'
It'has been said that the device may be used
in connection with spray-gun Jars and relative
ly small containers. Reference being had to Fig
me 9 it will be noted that the glass jar 21 is
provided with the usual screw-threaded neck 28
for which the invention was devised.
In reducing to practlce the invention as here
in shown and described, it is believed that I have
evolved and produced a comparatively simple and '
economical appliance. The adjustability of parts 40
renders the structure of a versatile character,
and it will doubtless be found aptly ?tted for the
purposes intended.

.the nature of a longitudinally elongated truss
50 or metal strap II. As seen in‘Figure 10, the strap
is provided with longitudinally elongated slots
II to accommodate and permit application and
adjustment of the retention clips or clamps 32.
Each clip is in the form of a small plate u hav
55 ing‘a wedge shaped tongue 34 at one end and a
curved edge law or detent at the opposite end.
The clip is provided with a screw threaded stud

II. The jaws II serve for gripping the outer pe
ripheral portion of the threaded neck 28. when
the clamping action is to be made from the
interior of the container the retaining clamps II
are moved or adjusted toward each other and the
especial retaining tongues 34 may be utilized.
These tongues may be engaged with the rim of
a can or the like somewhat in the manner shown
inll'igurelofthedrawings.

Coming now to the style of adapter disclosed
in Figures 1 to 3.inclusive, it will. be observed
70 here that the parts’, as a unitary assembly, is dis
tinguished by the numeral 38. 'Now whereas the
adapter unit 20 in Figure 9 is provided with a lat
requiring a further summation.
'
It is thought that the description taken in con
nection with the drawings will enable a clear un
derstanding of the invention to be had. There 60
fore.'a- more lengthy description is thought un
necessary.
While the preferred embodiment of the in
vention has been shown and described, it is to
be understood that minor changes coming with
in the field of invention claimed may be resorted
to if desired.
