ADJUSTABLE PAINT ROLLER Filed April 3, 1961 777m@ d. ikke/z INVENTOR.

United States Patent O 3,044,094 ADJUSTABLE RAINI ROLLER Merriil A. Ecker, 7005 NW. 42nd St., Bethany, Okla. Fiied Apr. 3, 1961, Ser. No. 100,158 4 Claims. (Cl. 15-230) This invention relates to paint applying devices and in particular to such devices of the paint roller type. Even more particularly the invention relates to an improved method of constructing a paint roller whereby the roller may be rigidly held either in a perpendicular or in a parallel position with respect to the handle of the paint roller.

Paint rolling devices are well known in the art. 'Iihese devices have gained increasing popularity over the conventional paint 'brush because of the speed with which they can be used and ease with which they can ordinarily be handled. In many instances, however, painters prefer to use a paint brush. One example of such an instance is where it is desired to paint the wall space close to the point where it joins the ceiling. This is true because the paint roller cannot be used for applying paint to such a surface without using a ladder. When a ladder is used, a small portion is painted, and then it is necessary for the painter to get of`r` the ladder, move the ladder, climb' the ladder again and paint another strip. This, of course, is tiring and time-consuming.

Various attempts have heretofore been made to modify the construction of the paint roller whereby it could be used to paint ceilings and also whereby the roller could be adjusted to various positions in respect to the handle. To the best of my knowledge none of these modifications have been entirely satisfactory. As for example those devices using an extension handle were rather cumbersome. v As another example, those devices wherein the roller was adjustable to various positions in respect to the handle were rather expensive to manufacture and yfurthermore the roller was not .rigidly held in the various positions.

It is, therefore, a principal object of the present invention to provide a paint roller which obviates the disadvantages of the prior art devices of this character.

It is another object of my invention to provide a paint roller vwhich is versatile, and which can be used to paint diiicult places without -additional equipment such as a ladder.

It is another object of the present invention to provide such a paint roller which is simple in construction and which can be manufactured and sold at relatively low cost.

Yet another object of this invention is to provide a paint roller wherein the roller may be held securely in perpendicular position with respect to the handle.

Yet another object of my invention is to provide a paint rollerwherein the roller may be held securely in a parallel position with respect to the handle.

Other objects and advantages of the present invention will become apparent as the following description proceeds.

To the accomplishment of the foregoing and related ends, said invention, then, comprises the features hereinafter fully described and particularly pointed out in the claims, the following description and the annexed drawings in which like numerals are employed to designate like parts throughout setting forth in detail certain illustrative embodiments of the invention, these being indicative, however, of but a few of the various ways in which the principle of the invention may be employed.

In said annexed drawings:

FIGURE 1 is a side elevation of the paint roller constructed in accordance to one aspect of the invention a paint reservoir therein may be used.

3,044,094 Patented July 17, `1962- ICC wherein the roller is securely held or locked in a posi-l tion that is perpendicular to the handle;

FIGURE 2 is a front elevation of the paint roller shown in FIGURE 1;

FIGURE 3 is a front elevation of the paint roller reduced in size wherein the roller is securelly held or locked in a'position that is parallel to the handle; and,

FIGURE 4 is a View on an enlarged scale of the locking device.

Referring to the drawings, in detail, FIGURES l or 2 show an axle frame 2 pivotally mounted on a handle portion 4 by means of the hinge 3 and held in position lby means of the locking devices 5. The roller l is mounted on the axle portion of the axle frame 2 and held in position by the retaining collar 7 and a similar retaining collar not shown at the opposite end of the roller. The method .of mounting the roller on the axle portion is fwell understood by those skilled in the art .and forms no part of this invention. If desired a hollow roller having Such hollow reservoir paint rollers are available on the open market.

As illustrated in FIGURE 2 one end of the axle frame 2 is bent upwardly at a right angle and then at another right angle so that the axle portion thereof is in parallel relationship to that portion of frame 2 which was not bent. Stated another way the axle portion is parallel to that portion which is secured to hinge 3 or other pivotal means. A preferred method of securing the axle frame to the hinge is by welding. Other means such as by screws or bolts may be used it desired. -Also as shown in FIGURE 2 the opposite end of axle frame 2 is bent downwardly at a right angle so that that portion will lie parallel land adjacent to handle portion 4. When soradjusted as illustrated in FIGURE 2 that portion of axle lframe 2 which lies parallel to handle portion 4 will be securely held in that position lby the locking device 5., These locking devices are used in pairs as illustratedv in FIGURE 1 and are so spaced that arather considerableA force is needed to force that portion of axle frame coming in contact with locking devices 5' over the shoulder of 5- until the frame rests at least partially in the concave portion of 5. After forcing the axle frame into such a position it is held there by means of friction and a rather considerable force is required to overcome that friction. In a preferred embodiment of the invention the locking devices 5 are inserted into handle portion 4 in pairs not parallel with each other but so that theyV toe-in slightly. This toe-in is very slight and is diflicult to see except by precise measurements. The advantage of utilizing the locking devices in this manner is that if as a result of wear they fail to hold the axle frame 2 securely it is only necessary to screw each device of the pair in slightly to restore proper tension.

My paint roller when the roller is clamped in the position as illustrated in FIGURES l and 2 is used in a manner similarly to that employed for using a conventional paint roller. If it is desired to paint a ceiling or other high sunface an extension handle 6 may be attached to handle portion 4. Extension handle 6 may be of any length desired by the painter. When it is desired to paint a surface such as a wall close to a point where the wall joins the ceiling best results are obtained if the roller is clamped so that it will be parallel to handle portion 4 as illustrated in FIGURE 3. Again an extension handle 6 of any length desired by the painter may be attached to item 4.

Items

4 and 6 may be constructed of almost any type of material such as Wood, plastic, metal or other suitable material. Generally I prefer to constnuct both item 4 and item 6 of wood. If lightness combined with strength is desired both of those items may be constructed of a metal alloy or aluminum tubing.

When item 4 is constructed of wood, locking device 5 is fitted with a wood screw. On the other hand if item 4 is constructed of metal, locking device 5 is provided with machine threads. In som-e instances under the latter condition locking device S may be provided with a sheet metal screw.

A preferred methodof attaching item -6 to item 4 is as illustrated wherein item 4 is provided with internal threads and item 6 with external threads adapted to tit said internal threads. Other means of attaching item 6 to item 4 twill be apparent to those skilled in the art.

The locking devices as illustrated are preferred but if desired other types of spring retaining clamps may be used. It is also considered to be within the scope of the invention to employ positive locking screw clamps such as for example, those -which are illustrated in U .S. Patent 2,845,647 dated August 5, 1958.

While particular embodiments of the invention have been described, it will be understood, of course, that the invention is not limited thereto since many modifications may be made, and it is, therefore, contemplated to cover by the appended claims any such modifications as fall within the true spirit and scope of the invention.

The invention having thus been described, what is claimed and desired to be secured by Letters Patent is:
