(01'. 15-2302 7' "This invention relates to improvements-in rollers particularly adapted for applying paint uniformly to surfaces and the principai objects of the invention are to devise an implement pre- 'sentingauniform pile coveredsurface which will roll smooth-1y over the surface to which the paint is to be applied and will spread the paint uniformly over such surface, to provide a simpleand efiective means for manipulating said roller in the application of paint to a surface and to devise a structure which will permit the easy and quick interchange of rollers;
f further object is to provide a formof roller which may be manufactured economically so that it-may be discarded and replaced without undue cost. I
The principal featurecf the invention consists iii-spirally mounting a length of textile fabric ilpon an open-ended cylinder; mounting bearing supports in the open end of said cylinder and rotatably securing said bearing supports and cyl inder from the shaft extension'of a handle.
A.- further important feature consists the novel manner of constructing the end closures and bearing supports for the cylinder" whereby a journal member is secured centrally in a cup or disc adapted to into and. sealthe ends of the cylinder.
-l'n the accompanying drawings Figure i is a plan view of a paint-applying in pleinent constructed in accordance wit'h this intention.
Figure 2 is an end elevational view. Figure 3- is a longitudinal part mid-sectional and part elevational view of a roller and bearing support constructed in accordance with this 2 The terminal ends of the textile strips may be firmly secured place in addition to. the adhesive by the use of wire staples 4 which may be driven into the cardboard and will gripand hold the terminal ends of the strips. It" will be noted in Figure 1 that any line extending lengthwise of the cylinder parallel its axis will intersectthe Figure 4 is an elevational View of the inside face of one of the end closure caps and journal bearing.
In the construction of the device herein shown thepaint-appl-yi-ngroller l is preferably formed of a plurality of substantially cylindrical laminations 2 of cardboard and on the periphery of this cylinder is spirally mounted a length or lengths of a suitable textile fabric 3 which is preferably a short pile fabric which, because of the spiral winding, presents a uniform cylindrical pile surface. The fabric is mountedupon the cardboard cylinder and secured by a suitable adhesiye so that the spiral edges of the fabric strips abut snugly and there-will. be no definite line of demarcation which might cause a bumping effect if the textile material were joined in a straight line lengthwise of the cylinder.
' flow at the seam.
spiral sea-m of the fabric 3 atonly two points affording extensive areas of pile surface side of the scam in directionof such line and also in the direction perpendicular to, the areas forming reservoirs" for paint storage of sufiicient I capacity to aiiord feed of'paintt'o a surface being coated to bridge said seam with undiminished In addition, the individual hairs of the pile 3' adjacent the spiral seam will bend in the direction of the pass and will tend to bridge said seam.
It will be understood that a cylinder such as described may be made in any desirable length and afterwards cut: into shorter lengths if desired to facilitate manufacture.
Sheet metal discs 5 formed with flanges 6' to fit snugly within the interior circumference of the cardboard cylinder are formed with outturned end flanges T, the sheet metal of the outer flanges being preferably rolled inwardly to. avoid. raw edges of the metal being exposed. These discs. when fitted into the ends of the cylinder have their end flanges! abut snugly against the ends of the cylinder.
The discs 5 are formed with circular central orifices and inserted into these orifices are the 9 on the outward side which abut the outer face of the disc; and said bushings are formed; with.
stepped shoulders a which extend through the holes in the disc and the. bushings are secured in place by deforming the edges of the shoulders '9 to.- form 10 which overlap the inside face 01 the disc: and thus hold the bushings securely in position- V It will be: understood of counse that these end discs. 5 may be made. fromv a solid. section otcast or machined metal if desired in which case the bushings would form. anintegral part of the disc but the construction described is preferable. Y
A handle ll has mounted therein a rod I 2 oi circular cross section which is bentat right angles for approximately a length slightly longer than half the length ofthe cylinder, being bent again at right angles to form a short length f3 which is formed with a right angle bend I 4 providing a substantially-'U-shaped structure the-endremote 2,545,700 v lies from the handle ll being of a length to extend through the paint-applying cylinder.
A collar I5 is rigidly secured on the rod which extends through the cylinder at a point adjacent to the bend i5 and abuts the bearing bushings in the cap inserted in one end of the roller formed by the flanged discs.
The outer end of the rod extends through and is journalled in the bushing in the disc at the opposite end of the roller and it is threaded to receive a suitable nut [6.
The roller is thus mounted on adequate journals at both ends and provides a tool for applying paint to surfaces which may be handled with ease and facility.
When it is desired to change the roller, either.
because of excessive wear or being allowed to dry with paint upon it or to use another colour of paint, it is simply necessary to remove the nut 16 from the threaded endlof the handle rod and withdraw the rod from the end discs, The discs may then be pried loose from the end of the cylinder and inserted in the fresh cylinder, When thus inserted the rod end is slipped into place and the nut replaced and the device is againready for use.
The spirally wound pile fabric mounted on journals in the manner described provides an exceptionally fine implement for applying paint to surfaces and its ready removal and substitution can be accomplished at very low cost.
What I claim as my invention is:
, l. A roller for applying paint comprising a cylinder open at the ends and having a textile paintapplying outer surface, circular members pressed into the ends of said cylinder and having peripheral flanges gripping the interior of said cylinder and each formed with a central orifice and an out-turned end flange projecting right angularly from its peripheral flange abutting the adjacent end of the cylinder preventing inward movement of said members. journal bushings extending through and secured in said central orifices in said members, said members forming both the sole means of supporting said journals bushings within said cylinder and the means maintaining separation of said journal, bushings with said journal bushings secured to and removable with said members from said cylinder, a rod having a handle extension removably and rotatably mounted in said bushings, a shoulder carried by said rod abutting the journal bushing of one of the said circular members, and a nut carried at the free end ofsaid rod and abutting the journal bushing of the other of said circular members effecting pressing of the circular members into the cylinder ends to grip said cylinder between said out-turned flanges to locate said bushings within said cylinder and to supcrt and hold said cylinder on said'rod.
2. A roller for applying paint comprising a replaceable cylinder open at the ends and having a textile fabric having a uniform pile surface spirally wound thereon pile outwardly and presenting a uniform cylindrical pile paint-applying outer surface with a continuous spiral seam to provide an even paint application throughout the length of said cylinder, circular members removably mounted in the ends of said cylinder and having right angularly turned flanges in tight frictional contact with the inner surface of said cylinder maintaining cylinder shape, and outturned end flanges projecting right angularly outwardly from the aforesaid flanges and abutting theend faces of said cylinder, each of said cir ting the journal bushing of the other of said circular members urging said members into said cylinder to grip said cylinder between said outturned end flanges anchoring said cylinder on said circular members and locating and anchoring said bushings in separated relation within said cylinder.
