The the nap before the staples are applied and sheet material 22 preferably is a carpet having cord-like nap 23, each of which is of substantially cylindrical cross section and adapted to stipple freshly painted surfaces without absorbing the paint or spattering it.
As shown in Figures 2 and 3, the meeting edges 24, 24' of the carpet 22 are connected by wire staples 25. The staples are positioned crosswise of the meeting edges and preferably in perpendicular relation thereto. The staples are appliedto the carpet when the carpet is in rolled up tubular form. The nap at the meeting edges is spread apart to provide a substantially flat cleared off junction at the meeting edges. The staples are applied so as to pass through both meetingedges and. the free edge portions of the staples are clinched against the inner surface of the carpet. The staples 25 are in spaced-apart relation along the length of the seam 26 and are positioned below the nap.
It has been customary heretofore to make stippling paint 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 a large number of tools from one location to another. With the removable and interchangeable structure herein described, the covering member may be readily removed from the roller carrier for cleaning the paint from the covering member and a clean covering member instantly applied. It is to be noted that I intend to use a number of sets of roller carriers and covering members, each set being of a different length, and all sets being used with the same handle 21. The cleaning operation of a covering member after use in stippling a painted surface is accomplished by placing the covering member in turpentine or in benzine or into another chemical which can dissolve and remove paint.
The covering member 20 is frictionally and removably mounted on the roller carrier [0. It is necessary to maintain the internal diameter of the covering member constant after repeated.
immersion in the paint removing solution. For this purpose I apply a coat of rubber cement 28 to the inner surface of the carpet. The layer of rubber cement imparts a degree of rigidity to the base layer 29 of the carpet 22 and maintains the tubular shape of the covering member.
The rubber coated inner surface prevents paint from seeping through the carpet. The rubber also provides a gripping surface causing the carpet to stick oradhere to the outer surface of the roller carrier. The rubber coating makes the base portion of the carpet substantially nonabsorbent whereby its internal diameter is maintained constant after repeated immersion in paint removing solutions.
Figure 1 shows the assembled roller carrier I supported on a multi-membered shank integral with the handle 21. It will be noted that the upper portion 30 of the shank has a bent side 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 in right angular relation with the roller carrier and has a threadably separable portion 34. The shank portion 33 has a threaded extension 35 designed to enter a threaded aperture in the shank portion 30. The shank members 30 and 33 may be of such length as to reach the ceiling portion of the room being painted-and this makes the threaded portion 34 subject to breakage. To prevent such breakage I provide a tubular outer member 36 fixed to shank member 33 and having a slight clearance hole in its upper portion to receive the shank member 30 in supported relation.
Breakage of the shank members is thus entirely prevented.
In assembling a roller carrier and handle, the
user aligns the threaded aperture 32 ofthe shank member 3| with one of the threaded ends I! of the axle l4 and engages the wing nut I8 and rotates the axle and thereby brings the said members into operative engagement.
It is to be noted that instead of connecting the meeting edges 24, 24 by wire staples, I may connect the said meeting edges by sewing them together. I may also connect the meeting edges by cementing a tape thereto at the interior surface of the carpet and lengthwise of the junction.
The junction of the axle l4 and the bent side 3| of the handle portion 30 is reinforced by a tubular outer member 31 which is integral with the axle at one end and embraces the handle portion 3|.
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 claim.
