ABSTRACT OF THE DISCLOSURE A roll applicator for paint having a roll receiving spindlewith a U-shaped bend on-one end, a first cupped stamping with a flat annular flange and a cylindrical side wall with the free end of the U-bend of the spindle extending thereth'rough, a second cupped stamping opposed to the first with an annular flange in frictional engagement with the first flange, a handle rod extending through the cupped sideof the second stamping, a pivot screw extending through the centers of the two stampings and the interior ends of the handle rod and the U-bend of the spindle, an interior nut clamping the end of the handle rod in the second stamping, a first exterior nut clamping the stampings together and a lock nut fixing the exterior nut in place.
A modified tool has a circular friction plate secured to the back of a squeegee blade, a single cupped stamping clamped in frictional engagement with the plate by a screw extending through the centers of the stamping and plate, and a handle r-od extending through the side of the stamping and engaged around the screw.
Outline of invention The invention provides an angularly adjustable and frictionally set connection between the handle and the work engaging element of a surface treating tool adapted to engage the surface being treated along a line. The angular adjustment permits the handle to be located at the most convenient position and angle for moving the tool in a direction transverse to its line of contact with the surface, while maintaining the desired pressure of the tool on the surface and the necessary force for moving the tool along the surface.
The drawings of which there is one sheet illustrate two forms of surface working tools with the adjustable handle connection of the invention incorporated therein.
FIGURE 1 is an elevational view of a paint roller mounted on the handle of the invention.
FIGURE 2 is an enlarged cross sectional view taken along the plane of the line 22 in FIGURE 1.
FIGURE 3 is a cross sectional view taken along the plane of the line 33 in FIGURE 2.
FIGURE 4 is an elevational view of the tool of FIG- URE 1 in a differently adjusted position and applied relation to a wall surface.
FIGURE 5 is an elevational view of "asqueegee like tool with the adjustable handle connection of the invention.
FIGURE 6 is an edge elevational view of the tool in FIGURE 5 applied to a working surface.
The tool shown in FIGURE 1 has a roller 1 having any desired surface composition for applying either paint or a cleaning solution to a wall surface. The roller is mounted on a spindle 2 in a well known manner and the rojecting end of the spindle 2 is formed with a generally U-shaped bend 3 with a free end 4 extending in spaced relation to the side of the roller. The free end 4 of the spindle is connected by the adjustable connection of the invention generally indicated at 5 to the end of a handle bar 6 having a grip 7 on its lower end.
The adjustable connection 5, as is more clearly shown in FIGURES 2 and 3, comprises a first cup shaped stamping 8 having a flat annular peripheral flange 9 and a generally cylindrical side wall 10. A second and similar cup shaped stamping 11 is arranged with its annular peripheral flange 12 in opposed frictional engagement with the flange 9 and with its cylindrical side wall 13 coacting with the cylindrical wall 10 to form an enclosure. A clamp bolt 14 extends through the center of the enclosure with its head 15 drawn against the outside of the stamping 11 by an adjustable thumb nut 16 bearing against the outside of the opposite stamping 8. Adjustment of the nut 16 determines the frictional resistance to turning between the two annular flanges 9 and 12 and the nut 16 is locked in its adjusted position by a wing nut 17.
The free end 4 of the U-bend of the spindle projects through a hole in the cylindrical flange 10 and is flattened as at 18 within the enclosure formed by the stampings to provide space for a hole 19 which freely passes the bolt 14. A small pin or rivet 20 secures the free end 4 of the spindle to the stamping 8. The end of the handle 6 similarly projects through a hole in the cylindrical flange 13 and is flattened as at 12 to provide stock in which the hole 21 is formed, also passing the bolt 14. An inner nut 22 securely clamps the head of the bolt against the lower stamping and prevents rotation of the bolt as the friction adjusting nut 16 is adjusted and as the spindle and upper stamping 8 are angularly and frictionally adjusted relative to the handle 6 and the lower stamping 11.
FIGURE 4 illustrates one of the convenient adjustments of the tool which locates the roller 1 in a vertical position while the handle 6 is angled downwardly and to one side of the roller so that the roller may be advanced horizontally in a straight line to apply paint or other surface treating material closely along the upper edge of a molding or window casing indicated at 23. Similar angular adjustments between the free end 4 of the bend in the spindle and the handle rod 6 are easily effected by overriding the frictional resistance between the flanges 9 and 12 so that the person using the tool can locate the roller 11 for the easiest application to the surface being treated.
FIGURES 5 and 6 show a modification of the work treating implement in which the surface engaging element is a flexible squeegee strip 24 secured in a suitable U- shaped backing strip 25. A metal connecting plate 26 is secured to the backing strip by rivets 27 and has its free end curved into the general plane of the squeegee strip and enlarged in a circular end 28. A cup shaped stamping 29 with a flat annular flange 30 is clamped in frictional engagement with the circular plate 28 by the bolt 31 passed through the bottom of the stamping and the circular plate. The handle bar 32 is passed through the side of the stamping 29 and secured around the shank of the bolt 31 in the same manner as the handle rod 6 of the roller form of the tool. A friction clamp nut 33 adjustably clamps the plate 28 and flange 30 together while the wing nut 34 locks the clamp nut in position.
As is indicated by the dotted line position in FIGURE 5, the handle rod 32 and its grip 35 can bea moved to the most convenient position for an operator to apply the squeegee strip 24 to a surface and move the strip or other surface treating element in a direction perpendicular to the line of engagement with the surface.
What is claimed as new is:
1. A tool having a surface treating portion adapted to engage a surface along a straight line, and a grip with a handle rod extending therefrom comprising a supporting element for said surface treating portion having a free end located in spaced relation to the line of contact of said surface treating portion and centrally thereof,
a first annular friction surface on said supporting element,
a cup shaped stamping having a hole in its side through which the end of said handle rod extends, and having an annular flange forming a second friction surface opposed to said first friction surface,
a clamp bolt extending centrally through said supporting element and said stamping and through a hole formed in a flattened end on said handle rod,
a nut on said bolt clamping the bolt against rotation relative to one of said friction surfaces,
and a finger nut on said bolt adjustably clamping said stamping to said supporting element to hold said friction surfaces together.
2. A tool as defined in claim 1 in which the surface treating portion is a roller and the supporting element is a spindle rod for the roller having a U-shaped bend on its outer end, v
and a second cup shaped stamping having a peripheral edge forming said first friction surface,
the outer end of said U-shaped bend extending through the side of said second stamping and being flattened to define a hole passing said clamp bolt.
'3. -A'tool as=defined in claim 2 inwhich the means clamping the bolt against rotation is a nut located between said stampings and clamping one of said flattened ends to the adjacent stamping 4. A tool as defined in claim 3 in which the other of said flattened ends is secured to the bottom of the adjacent stamping. v 1
