PAINT ROLLER Filed March 23, 1966 v United States Patent Ofice 3,421,822 Patented Jan. 14, 1969 U.S. c1. 401-137 Int. Cl. B4411 3/28 1 Claim Paint rollers with direct or indirect automatic feeding are generally mounted on fittings comprising a fixed shaft.

The horizontal shaft on which the roller pivots is necessarily in the form of an angled or stirrup-shaped piece and thus has a projecting part which prevents the tool from contacting profiles such as corners of walls, etc. Since, moreover, the distributing device has to be positioned in a preselected manner, it is not possible to reverse the support as in the case of manual rollers.

These devices therefore cannot be effectively used in all the application for ordinary paint rollers. f

The object of the invention is to provide a roller supporting mounting which will be reversible and adjustable in its direction and will enable the paint to be distributed along skirtings, corners etc., without leaving an unpainted edge or border as a result of the space occupied by the framework of the mounting.

It is characterized by the means employed, considered both in conjunction with and independently of one another, and more particularly by a fixed assembly consisting of the handle and the tap of the tubular element,

equipped at its end with the spreading surface, and the horizontal portion of this tubular element bears the assembly .surface which accommodates the bent mounting of the roller. This assembly surface consists of a profiled part secured in the centre, a threaded rod being situated in its axis and accommodating a securing screw, and of two symmetrical horizontal supporting portions; it thus sufiices to fix the movable interchangeable mounting, fitted with the same securing device, on the right or on the left, by means of the securing screw.

In the accompanying drawings illustrating one possible embodiment of the invention, without any limitative effect:

FIGS. 1 and 2 are elevations of the movable mounting, assembled in the two directions respectively.

FIG. 3 is a side view of the apparatus as a whole FIG. 4 is a view, in perspective, of the positioning device.

FIG. 5 is a schematic tion of the fixed spreading surface, roller.

FIG. 6 shows an alternative application of the mounting with a number of elements.

The apparatus consists of a fixed assembly, as in FIGS. 1, 2 and 3 consisting of the handle 1, the body of the tap 2 and the tubular fitting 3 supporting the inclined distributor 4.

The securing element for the bent fitting supporting the roller consists of a U-shaped axial positioning section 6 continuing towards each side in the form of horizontal supporting

surfaces

7 and 8 respectively. A screw-threaded securing bar 9 is situated in the axis of the positioning rib.

The removable mounting in FIGS. 1 and 2 consists diagram of the angle of projecin relation to the of a bar 10 of which the end is integral with a securing element 11 having the same profile as the fixed element shown in FIG. 4 but provided with an axial orifice 12.

The

bearing surfaces

13 and 14 rest against their counterparts 7 and '8, like jaws, under the action of the nut 15.

This bar 10 continues in the form of the right-angled bend 16 and the corresponding bend 17 which leads into the shaft 18 on which is mounted the roller 19, of which the bearing is immobilized by the nut 20.

The distributor 4 emits a certain amount of paint in the direction shown by arrow 21, in front of the roller, which simply spreads the layer already adhering to the wall to be treated.

According to the alternative version shown in FIG. 6 this mounting can comprise a number of

rollers

22, 23 and 24 afiixed to the removable mounting 25.

s The advantages of this device will thus be obvious.

The assembly for automatic emission of paint, as shown in FIG. 6, and comprising either a single roller or a number of rollers, will always be extremely easy to operate, without reversing, twisting or any other such manipulation.

It suflices for the operator to place the bend 16, as in FIG. 1 or 2, on the right or on the left, in order to operate on corners of walls, floor skirtings or other parts of the room, in all possible planes.

The offset position of the mounting, moreover, enables this rotation to be elfected rapidly, without completely releasing the securing nut or removing the mounting from its support. i

There will no longer be any inaccessible areas, despite the fixed position for the distributor 4.

This adjustable mounting characterizing the invention is also interchangeable and makes it possible, with a single spreading support, to attach combined rollers, such as rollers with contours in relief, rollers with flexible linings having small points, and even devices with multiple distributors.

The shapes, dimensions and arrangements for the various elements may nevertheless vary, within the limits allowed by equivalent devices, as may also the materials used for their manufacture, without thereby departing from the principle of the invention described in the foregoing.

I claim:

1. A paint roller comprising (a) a roller support in the form of a U-shaped rod having a longer arm and a shorter arm, said arms being parallel, said longer arm carrying a nut threaded on its free end and serving as a paint roller bearing, said shorter arm having an arched portion adjacent to the free end and having an aperture formed centrally in said arched portion,

(b) a paint distributor assembly comprising a handle and a paint supply conduit and a tap in said conduit and a tubular T-shaped body, the stem of said T- shaped body carrying a threaded journal engaged through the aperture of the roller support and carrying a nut, said body having an arched formation against which the arched formation of the roller support arm seats the head of said T-shaped body being apertured and lying parallel to and spaced from the axis of said longer arm of said roller support whereby said roller support and distributor assembly may be selectively located in two positions ofrelative rotation 180 about the axis of said jour- FOREIGN PATENTS nal, as determined by engagement of said arched 1 fi fi a formations one on the other.
