1 Clam. (Cl. 15-132.5)
The present invention relates to the general` class of implements or appliances of the hand operated type for applying liquid coatings, and more specically to 'an improved self-dispensing roller for applying paint of the fountain roller and web class, which' while well adapted for applying varnish,` enameLand other liquidcoatings to building structures, Iwill hereinafter'be referred to as an applicator 'for liquid paints."
The primary object of the invention is the provision of a manually'operated implement of this character that is composed of a minimum number of parts thatV may with facility be manufactured with a low costof production, the component parts may be assembled'vvith convenience,
to constitute a unitary structure-'that may be` manipulated easily to apply'auniformly smooth coating with `a minimum expenditureof time andlabor.y a i l The invention consists in certain novel features of construction and combinations and arrangements of parts involving a rotary reservoir 'or roller and its supporting handle-frame as will hereinafter be described in detail and more particularly pointed outY in thev appended claim.
In thev accompanying v drawings We have illustrated a complete example of a physical embodiment of our invention in which the parts are combined and arranged in accord with one mode we have devised for the practical applicationof the principles of.. the invention. It will however be understood that changes t'and-v alterations, are
contemplated and may be made in these exempliiying drawings and mechanical structures, within the scope of our claim, without departing from the principles of the invention.
Figure 1 is a plan view of an applicator involving our invention, part of the web or porous cover being broken away to disclose the distributing ducts and ports of the rotary reservoir or roller.
Figure 2 is a sectional end view as at line 2 2 of Fig. l.
Figure 3 is a sectional View on the line 3-3 of Figure 6.
Figure 4 is an enlarged detail sectional view of the roller as at line 4-4 of Fig. 1.
Figure 5 is a detail sectional View showing one of the exterior ducts and a port of the roller.
Figure 6 is a longitudinal sectional view of the implement together with its supporting handleframe.
Figure 7 is a transverse sectional View at line 1-1 of Fig. 6; and Figure 8 is a transverse sectional view at line 8 8 of Fig. 6.
Figure'9 is a sectional detail View of the adjustable handle.
` Figure 10 is a fragmentary detail View showing the means for preventing longitudinal displacemerit of the "journal for the rollers; and Figure 1l is"`aV transverse sectional view at line II--I--I ofFig.10.` 3- I In carrying out our invention-we employ a rotary reservoir in the nature of ar tubular or cylindrical roller I, preferably of molded plastic material, having a closed end 2 integral there with,l and ahead `3 of similar material, or .other suitable material, and the head is provided with an annular beveled flange 4 that fits over a cornplementary beveled edge 5 of the roller to insure a sealedjoint. y,
The exterior surface of the roller is provided with a series of equally spaced right hand spiral grooves 6, and a complementary series of equally spaced left hand spiral grooves 'lthat intersect,
Vand the intersections' of these grooves or distributing ducts are fashioned with orices or ports 8 to insure an equalized distribution of the liquid paint from the interior of the roller, or reservoir, through the ports. and thence through the networkof ducts to an enclosing web or porous cover 9 of the roller. 'f l a a j yIn its initial form, the `web or ,cover is an 'absorbent rectangular mat, of porous material that is adapted to be permeated or impregnated lwith `the liquid paintl from the network of ducts,` and the mat is Wrapped around thecylindrical roller as a cover, and in the form of a4 cylindrical tube.
For securely uniting the porous web with the roller the latter is provided with an inner longitudinally extending rib II] that forms an exterior joint groove II, and the adjoining ends I2 of the mat are firmly pressed into the groove to form an attaching bead rrnly embedded in the groove, and presenting a smooth exterior surface for the web or cover.
The ends of the tubular cover may be retained on the exterior of the roller, as by means of annular groove threads I3 that are equally spaced from each other and extend circumferentially of the roller. The grooves I3 also tend to seal the ends of the roller to prevent the paint from flowing out of the grooves 6 and 1 over the outer ends of the roller.
The reservoir formed within the hollow roller may be lled or replenished with liquid paint through a lling hole I4 in the head 3 of the roller, and the filling hole is closed by means of a tapered plug I5 that is frictionally held in thewalls of the lling hole.
to receive one end of a tubular bearing or `sleeve l 2|, the other end of which is threaded and-screwed into complementary threads of the bushing I1. A
For mounting the bearing sleeve in the recessed boss 2U the end of the sleeve is threaded to receive the threads of a lock 1nut 22 which Yhas a head 23 for use with a wrench or other tool, and
a packing ring 24 is employed in the recessed boss `toseal the .joint against leaks from the interior of the reservoir.
. The roller is equipped with a handle frame of special design that includes an end piece 25 'enclosed within and extending the l'ength of the bearingsleeve, which forms a journal bearing for the bearing sleeve ao'out'vvhich the roller revolves as the implement is manipulated across the surfao'eto be painted. -fIo prevent longitudinal dis- .placement of the journal bearing, or the handle frame, the journal 25 is Vprovided with an annular .groove 26 in which is mounted a split ring 21 located between an end ofthe 'sleeve and within the Anut 22; and the nut; which tightens the cap or head 3 on the roller, also securely mounts the journal in its bearing sleeve.
AAs best seen in Figs. 1 and 6, the handle-frame, in addition to the journal 25 also includes a return-bend yoke 28, and an arm 29 parallel with the journal 25, vand this arm terminates in an integral shank 30 disposed radially of the roller.
An adjustablesleeve 3l having internal threads ltoreceive the threadedend of the shank, is also provided with external threads for mounting a handle 32 rigidly on the sleeve, and it will be apparent that the handle may be adjusted on the threaded shank Yto lengthen or shorten the support for the handle as the roller or Vapplicator is reciprocated for 'applying 'the "liquid `coating to a surface.
Q As the roller is manually reciprocated, or stroked, over a desired surface, and with the porous Web in contact therewith, the roller re- 4 volves upon its journal bearing, and the liquid paint is fed from the interior reservoir through the ports and the net-Work of ducts, and thence through the porous web or cover, for uniform and equal distribution of the paint to assure a smooth and even painted surface.
Instead of retaining the: ends of.- the tubular cover on the exterior ofthe rollferaspreviously described, drawstrings 33 may be used so that the cover is removable, and can be easily removed and replaced as desired.
f `Having thus `fully described our invention, what "We claim as new and desire to secure by Letters Patent isa,
In a fountain applicator for liquid paint, the combination with a supporting handle frame including Ya 'journaLfof a cylindrical roller having a porouspad and an interior reservoir, means for feeding liquid paint from the reservoir to the inner surface of the .porous pad, said roller having tubular end-bosses formed on the interior surface of the ends of s'aid roller "centrally thereof, a
Ybushing mounted i'nofnejboss, a bearing sleeve extending through the 'reservoir and surrounding the journal and Vhaving one end threadably connected-to said bushing, a lo'ck nut located in the other boss surrounding th'e""j`o`urnal and 'threaded on the sleeve, and'means for retaining the'journal against longitudinal displacement.
