ROLLER TYPE PAINT APPLICATOR Filed Feb. 1, 1950 INVENTOR. M'iae/ 7. a/ 521.57

Patented July 21, 1953 PA ENT OFFICE I ROLLER TYPE PAINT APPLICATOR Michael Peter Vengris, Dearborn, Mich assignor to The Drum Corporation, Detroit, Mich., a corporation of Michigan Application February 1, 1950, Serial No 141 784 4 Claims. (01. 29 116) The present inventionrelates to improvements in paint rollers, or liquid contact applicators.

Hand tools have been employed which comprise contact rollers having pile fabric surfaces with the rollers rotatably mounted on handles.

The pile fabric covers are usually removable so that they may be cleaned, but in prior constructions the covers and their mountings have been such that proper cleaning is not attained and the covers have a comparatively short life. According to the present invention, the covers are mounted on the rollers in an improved manner so that they may be easily applied or removed :and easily cleaned.

One of the primary objects of the present invention is to provide an improved way of applying and attaching the cover to a roller so that it may be easily applied and removed and the cover may be easily and thoroughly cleaned.

A further object of the invention is to provide an improved hand tool of the type mentionedv which is economical to manufacture.

Other objects of the invention will become apparent from the following specification, the drawing relating thereto and from the claims hereinafter set forth.

In the drawing, in which, like numerals are used to designate likeparts in the several views throughout:

Figure 1 is a cross-sectional view of a paint contact-roller, showing the handle upon which the roller is mounted in elevation;

Figure 2 is an enlarged, cross-sectional view taken substantially along the line 2-2 of Fig ure 1; a I

Figure 3 is an enlarged, cross-sectional view taken substantially along the line 33 of Figure 1;

Figure 4 is a partial end view of the roller and illustrates the manner of applying the cover to the mounting member; and

Figure 5 is a perspective view of a pile fabric cover employed with the present invention.

Referring to the drawing, a paint contact roller is generally indicated at I and is rotatably mounted upon a handle, generally indicated at 2.

The handle 2 comprises a hand grip 3 having a rod or tube 4 projecting from one end thereof which is reversely bent to provide a mounting shaft 5. The hand grip 3 is substantially normal to the axis of the mountin portion 5.

The contact roller l comprises an'elongated tubular member 6, which is preferably formed of metal and which has a longitudinally extending slot 7 completely therethrough. The mounting 2 tube 6 is thus resilient and may be compressed slightly when the cover 8 is applied thereto.

The cover 8 is a pile fabric, such as mohair, and is formed of a rectangular sheet of such material. The adjacent edges of the sheetare brought together and stitched, inwardly of the edges, as indicated at 9. The cover is then turned inside out, so that the stitched edges form a radially inwardly directed flange 10, as indicated in Figurefi, with the fibers of the cover directed outwardly. and the dimensions are such that when it is applied to the mountin member 6 the member 6 is slightly sprung inwardly, so that after the cover is mountedon the member. 6- it is firmly held thereona The cover 8 is longer than the mounting member for a purpose which will be described hereinafter. r

The cover 8 is mounted on the tubular member 5 so that the inwardly directed flange Ill of the cover is received within the slot 7. The ends of the cover 8 project beyond the endsof the mounting tube 6, as indicated in Figure 4.

In order to secure the cover 8 to the tube 6 in the tube 6 and the inner annular flange I 3 has greater depth, or projects radially inwardly a greater distance, than the outer flange l2.

' The cover 8 is secured to the member 6 and the assembly is mounted on the shaft 5 by means of metal disks or washers I 4. The disks have an external diameter, slightly larger than the internal diameter of the flanges l2 but substantially larger than the internal diameter of the flanges I3. The disks l4 also have central openings l5 therethrough, through which the shaft 5 gfojlects for rotatably mounting the roller assem- In applying the cover 8 to the mounting member 6, it is telescoped over the member 6 with the flange It! received within slot 1 and with both ends of the cover 8 projecting beyond the ends of the tube'6, as described above. The overhanging ends of the cover 8 are then turned inwardly, as indicated by the brokenlines in Figure 4, so that such inturned ends overlie their adjacent grooves H. The disks M are then forced into their adjacent ends so that they snap over flanges l2 and clamp the intucked ends of the cover 8 into grooves II. The inner annular It is thus in tubular form a flanges I3 serve as stops to limit the inward movement of the disks I4.

The assembly may then be applied to the shaft 5 so that such shaft is received through openings I5 in the disks I4. In order to properly position the roller assembly I on the shafts 5, axial movement in one direction is limited by tabs or projections I6 which may be struck in the shaft 5 adjacent the bent end, and a washer I1 is received over the shaft 5 adjacent the projection I6 against which the adjacent disk I4 abuts. The shaft 5 projects slightly beyond the opposite disk I4 and a washer I8 may be disposed over the shaft 5 on the outside of the adjacent disk. The end of shaft 5 is formed with a groove I9 and a snap button is snapped over the end of the shaft 5 within groove I9 so that the contact roller assembly I is rotatably held on the shaft against axial displacement.

To remove the roller, it is merely necessary to take off the snap button 20 and the washer I8, and the assembly may be pulled off shaft 5. It is then only necessary to insert a tool, such as a screwdriver, in the opening I5 of each disk and snap it out of groove I I. The ends of the cover 8 may then be pulled out and the cover removed from the mounting tube 6. It may then be thoroughly cleaned and re-applied for the next use.

Formal changes may be made in the specific embodiment of the invention described without departing from the spirit and substance of the invention, the scope of which is commensurate with the appended claims.

What is claimed is:

1. In a liquid applicator tool, a cylindrical member, means forming an internal annular seat in each end of said member, said last named means comprising a pair of longitudinally spaced, inwardly directed flanges adjacent each end of said member, the inner flange of each pair extending farther inwardly than the outer flange, a cover embracing said member, the opposite ends of said cover being turned in around the ends of said member to overlie said seat-s, a disk disposed within each end of said member holding the inturned end of the cover within its seat, and means forming aligned central openings in said disks.

2. In a liquid applicator tool, a cylindrical member, means formin an internal annular groove 1 in each end of said member, said last named means comprising a pair of longitudinally spaced, inwardly directed, annular flanges adjacent each end of said member, the inner flange of each pair extending farther inwardly than the outer flange, a cover embracing said member, the opposite ends of said cover being turned in around the ends of ,said member to overlie said grooves, a disk disposed within each end of said member holding the inturned end of the cover within its groove. the construction and arrangement of said flanges and the disks with respect to each other being such that the disk may be snapped over the outer flange and the inner flange serves as an abutment, and means forming aligned central openings insaid disks.

3. In a liquid applicator tool, a cylindrical member having a longitudinal extending slot therethrough, means forming an internal annular groove in each end of said member, said last named means comprising a pair of longitudinally spaced, inwardly directed, annular flanges adjacent each end of said member, the inner flange of each pair extending farther inwardly than the outer flange, a cover embracin said member, the opposite ends of said cover being turned in around the ends of said member to overlie said grooves, a disk disposed within each end of said member holding the inturned end of the cover within its groove, the construction and arrangement of said flanges and the disks with respect to each other being such that the disk may be snapped over the outer flange and the inner flange serves as an abutment, and means forming aligned central openings in said disks.

4. In a liquid applicator tool, a cylindrical member having a longitudinally extending slot therethrough, means forming an internal annular groove in each end of said member, a pile fabric cover embracing said member, said cover having the adjacent edges inturned and the inturned edges received within said slot, the opposite ends of said cover being turned in around the ends of said member to overlie said grooves, a metal disk disposed within each end of said member holding the inturned end of the cover within its groove, and means forming aligned central openings in said disks.
