Claims
It will be obvious that various changes and departures may be made
to the invention without departing from the spirit thereof and
accordingly, it is not intended that the invention be limited to
that specifically described in the specification or illustrated in
the drawing but only as set forth in the appended claims
wherein:
1. A dual paint roller device adapted to travel forward and
rearward to apply paint to a surface comprising a pair of paint
applicator rollers, said rollers being spaced from one another with
one of the rollers being positioned with its inner end overlapping
in front of the inner end of the other roller, said rollers
extending outward in length at a rearward inclined angle in
opposite directions to one another, a bracket disposed between the
inner ends of the rollers with said rollers being rotatably mounted
to said bracket, a handle having its one end rotatably mounted to
said bracket to rotate about a horizontal axis extending laterally
of the line of travel of the device, said rollers overlapping each
other sufficiently whereby when the device is moved forward along
its line of travel to apply paint any ridge of paint left along the
inner end of the front roller will tend to be smoothed out by the
inner end of the rearward roller following in the path thereof.
Description
This invention relates to paint applicators, more particularly, the
invention relates to paint roller devices.
It is an object of the invention to provide a novel dual roller
paint applicator having a pair of rollers mounted at off set angles
to one another and to their line of travel in applying paint so as
to cause a brushing action as well as a rolling action in applying
the paint, with a central handle for operating the applicator.
It is a further object of the invention to provide a novel dual
roller paint applicator with a pair of rollers mounted at angles to
one another to create a brushing action in applying paint.
It is another object of the invention to provide a novel dual
roller paint applicator having a pair of rollers mounted at angles
to their line of travel in applying paint.
Further objects and advantages of the invention will become
apparent as the description proceeds and when taken in conjunction
with the accompanying drawing wherein:
FIG. 1 is a top plan view of the dual paint roller invention.
FIG. 2 is a side elevational view of the dual paint roller
invention.
FIG. 3 is a cross-sectional view taken along line 3--3 of FIG.
1.
Briefly stated, the invention comprises a dual paint roller
applicator having a pair of rollers rotatably mounted to a bracket
at angles to one another and to their intended line of travel in
applying paint to a surface, a handle is pivotally mounted to the
bracket with the handle having its longitudinal axis lying parallel
to the intended line of travel in applying the paint.
Referring more particularly to the drawing, in FIG. 1 the dual
paint roller applicator 20 is illustrated as having a center
bracket 21 with a pair of rollers 22 and 23 rotatably mounted to
the bracket 21 at angles to one another, and at angles to their
intended line of travel when applying paint, as indicated by the
arrows 24 and 25. A handle 26 is pivotally mounted to the bracket
21 for operating the applicator invention 20.
The handle 26 has a wooden grip portion 27 with a steel rod 28
extending out of the forward end 27' of the grip member 27. The rod
28 has a curved portion 29, so as to be able to clear the roller
22, when applying paint, and the forward end of the rod 28
terminates in a laterally extending straight cylindrical shaft
portion 31. The bracket 21 has a cylindrical sleeve member 32 and
the shaft portion 31 is rotatably mounted in the sleeve 32 to
rotatably connect the handle 26 to the bracket 21.
The bracket 21 has a pair of elongated arms 33 and 34 extending
outwardly from opposite sides of the sleeve member 32 and fixed
thereto. Each arm 33 and 34 has an enlarged socket member 35 and
36, respectively, at its outer end, with the interior of each
socket being threaded to threadably receive the threaded ends 37'
and 38' of bolts 37 and 38.
The paint rollers 22 and 23 are each of a conventional construction
having a fibrous cylinder or sleeve member 39 with metal end caps
40 and 41 fitted into the ends of the sleeve member 39. The end
caps 40 and 41 each have a center bore for their respective bolts
37 and 38 to pass through with the enlarged heads 43 of the bolts
37 and 38 holding their respective rollers 22 and 23 onto the bolts
at one end and the sockets 35 and 36, respectively, holding the
rollers 22 and 23 onto the bolts at the other end, while permitting
the rollers 22 and 23 to rotate on the bolts 37 and 38.
The fibrous sleeve member 39 of the rollers 22 and 23 are for
absorbing and applying paint onto a surface.
OPERATION
The dual paint roller applicator 20 operates as follows:
The rollers 22 and 23 will be dipped into wet paint and its fibrous
surface of their sleeves 39 will absorb the wet paint. The dual
paint roller applicator will then be placed upon the surface 44 to
be painted in the manner illustrated in FIGS. 1 and 2 with the
lower edges 45 of the sleeves 39 flush with the surface 44 and the
roller applicator will then be moved forward and backward in the
direction of either arrows 24 and 25, by the operator gripping and
moving the handle endwise in either direction.
When the applicator 20 is moved forward in the direction of arrow
24, the rollers 22 and 23, being inclined to the line of travel
with the brush as well as roller as the applicator moves with the
rollers 22 and 23, tends to spread the paint apart.
When the applicator is moved backward, in the direction of arrow
25, the rollers 22 and 23, being inclined to the line of travel,
will then bring the paint together, the rollers forming an acute
angle to the entire line of travel. The rollers 22 and 23 will also
when moving backwards brush the paint as well as roll the paint
onto the surface.
The brushing action of the roller by the rollers not having their
axes perpendicular to the line of travel, results in a better
penetration of the paint into the surface particularly on rough or
pitted surfaces.
Therefore it will be seen that a novel dual roller application has
been provided which creates a brushing as well as a rolling action
in applying paint for better penetration of the paint into the
surface being painted.
The overlapping of the rollers 22 and 23 to their line of travel
also tends to eliminate a ridge of paint in the center of the
device as it moves along.
