2 Claims.

This invention relates to roll-stipplers having replaceable frictionally supported cardboard tubes covered all over its outer surface with a yielding material such as carpet, rubber, and the like, and used in impressing designs on coated surfaces, particularly on building walls being painted.

An object of this invention is to provide a rotatably mounted roll carrier or supporting member made of metal and having a yieldably covered tube removably secured on said carrier, the said tube being easily removed when covered with paint and a clean tube mounted on the carrier.

Another object of this invention is to impregnate the cardboard tubes with a chemical such as glycerin or other repellent of paint removing liquids such as benzlne or turpentine to prevent softening and destruction of the tubes.

Another object of this invention is to provide a stippling roller supported on end members having resilient action and being thereby adapted to stipple uneven surfaces.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawing and pointed out in the claims which form part of this specification.

Reference will now be had to the drawing, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a central cross-sectional view of the roller carrier.

Figure 2 is a cross-sectional view, the section being taken as on line 2-2 in Figure 1.

Figure 3 is a plan view of the stippling roller, partly brokenaway to show the interior of the roller.

Figure 4 is a cross-sectional view, the section being taken as on line fl--4 in Figure 3.

Figure 5 is a fragmentary cross-sectional view of a modified roller carrier.

Figure 6 is a side elevation, on a reduced scale, of the roller carrier and a guard, the roller being removed.

Figure '7 is an end view of the roller carrier and guard shown in Figure 6.

Figure 8 is a fragmentary portion of the shank, showing means for supporting the guard member.

In the illustrated embodiment of the invention, the numeral l indicates a tubular roller carrier comprising a thin metal casing ll having dishshaped end members l2, l2, made of metal and 1940, Serial No. 354,624

(Cl. ll-5.5)

being fixedly secured at opposite ends of the casing.

Each end member l2 has a central aperture l3 designed to receive reduced bearing portions of an axle M on which the tubular carrier H is mounted for free rotation. Each end member l2 has a flange l which causes the end members to remain in mechanically interlocked relation with the tubular casing and so that the axle is at all times freely rotatably mounted in relation 10 to the casing.

As best shown in Figure 1, each end member I2 is positioned within the casing in a manner to provide a large central opening 16 serving to house threaded ends l1, ll, of the axle l4. Each end l'l terminates inwardly of one of the end faces of the casing ll. One threaded end ll of the axle M has a wing nut l8 threaded thereon.

As shown in Figures 3 and 4, I have provided a stippling roller 20 comprising a cardboard or 20 other fibrous tube 2| having a sheet of yieldable material 22 cemented thereto in unitary relation. The cemented sheet material 22 may be carpet having cord-like nap 23 which is adapted to stipple freshly painted surfaces without absorb- 25 ing the paint or spattering it.

It is to be noted that while I have shown in the drawing a carpet covered fibrous stippling roller designed for stippling painted surfaces, that I may employ rubber covered fibrous tubes or covering members having plain, corrugated, or comb-like outer surfaces for smoothing or design imprinting surfaces to be decorated.

It has been customary heretofore to make stippling rollers integral with the roller carrier. In practice, it is found necessary to have an assortment of stippling rollers of various lengths, which is a detriment when the painter has to move his tools from one location to another. With the removable and interchangeable struc- 4O ture herein described, the roller may be readily removed from the carrier for cleaning the paint from the roller. This cleaning operation is done by placing the roller in turpentine or in benzine or into another chemical which can dissolve and remove paint.

In order to prevent the cardboard or fibrous absorbent tube 2| from swelling when dipped in paint remover, I impregnate the said tube with glycerin or similar chemical which is a repellent to paint dissolving liquids.

Figure 5 is a fragmentary cross-sectional view of a roller carrier 25 having modified end members 26 made of molded rubber having a resilient action transverse to the axle Id. The

side wall of the member 26 may have apertures 21. This resilient action is particularly desirable when stippling on omamenting walls having uneven surfaces. The rubber members 26 absorb the shocks when operating the roller at high speed.

Figures 6 and 7 show an assembled roller carrier I supported on 'a multi-membered shank integral with the handle 30. It will be noted that the upper portion of the shank consists of a bent member 3|, the uppermost end of which is horizontal and has a threaded aperture 32. The aperture 32 is adapted for threaded engagement with one of the threaded ends I! of the axle l4.

The lower portion 33 of the shank is positioned crosswise of the roller and forms a threadably separable portion 34, best shown in Figure 8. The shank portion 33 has a threaded extension 35 designed to enter a threaded aperture in the crosswise lowermost portion 36 of the shank member 3|.

An elongated member 31, of semi-circular cross-section, has an aperture for engagement with the separable portion 34 of the shank members, and when in the fixed operative position below the roller 20, the member 31 provides a guard for the entire lower half of the roller.

It is to be noted that I intend to use a number of sets of roller carriers and rollers or covering members, such as parts numbered I 0, and 20, each set being of a difierent length. These sets of roller carriers and removable yieldably covered rollers can be operated with the same handle 30 and with the same shank members 3| and 33. I have found it necessary to make the horizontal lengthwise portion 38 of the member 3| less than half the length of the longest roller, so that the handle 30 will not be in the middle of the longest roller, and so that when a short roller is used the handle will be beneath said roller and not in offset relation.

In assembling a roller carrier and handle, the user aligns the threaded aperture 32 of the shank member 3| with one of the threaded ends I! of the axle l4 and engages the wing nut l8 and rotates the axle and thereby brings the said members into operative engagement.

In assembling a metal casing H and two end members l2 for integral connection, I preferably center punch the outer surface of the casing against the end members to interlock these members.

In accordance with the patent statutes I have described and illustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended claims.

I claim:

1. In an interchangeable stippling roller mechanism, comprising a tubular roller carrier, an axle, said roller carrier having dish-shaped and centrally apertured end members mounted therein and being rotatably mounted on said axle, each of said end members having a flange and being in interlocked relation with said roller carrier, said axle terminating short of the end faces of said roller carrier, said axle having threaded ends, a tubular stippling covering member having an internal diameter adapted to frictionally and removably engage said carrier, a handle having means for threaded attachment solely to one of said threaded ends of said axle, said roller carrier being thereby unobstructed at one end to permit quick removal and replacement of covering members of various lengths thereon, said end members being resilient in a direction transverse to said axle and thereby adapting said stippling roller to stipple uneven surfaces.

2. In an interchangeable stippling roller mechanism, comprising a roller carrier, an axle, said roller carrier having dish-shaped and cent-rally apertured end portions and being rotatably mounted on said axle, each of said end members having a flange and being in interlocked relation with said roller carrier, a tubular stippling covering member having cord-like nap and having an internal diameter adapted to frictionally and removably engage said roller carrier, a handle forming a continuation of one end of said axle, said roller carrier being thereby unobstructed at one end to permit quick removal and replacement of tubular stippling covering members of various lengths thereon.

CARNIG A. HARPOOTLIAN.
