Thisiinvention rela'testo painting and decorat ing toolsand has particular reference to adevice for rolling paint onto a wall or .other .fia't surface.
An object of the invention is to generallyim prove devices of this character and to ,provide apa'int roller which is simple in construction, economical to manufacture andeffic'ient in .operation.
AIlOfihBl object of the invention is .the provision of a device of the character indicated which .is constructed of a minimum number of parts.
Another object of the invention is the provision of a device of the character indicated which is constructed and arranged so that the paintcarrying elements are rigidly supported for rotating act'on about their longitudinal axis, whereby any tendency of the roller to wobble is obviated.
Another object of the invention is the provision ofapaint roller which is constructed with spacedresilient end members which are arranged to frictionally engage and support 'a rigid 'tubular member, on which is mounted a paint-transferring element.
Another object of the invention is the provision of a paint roller which is constructed and arranged so that the paint-transferring element is supported throughout a sufficient portion of its length, so as to prevent the paint-transferring member from twisting about its longitudinal axis when the roller is in use.
Other objects and advantages of the invention will become apparent as the description proceeds, reference being made to the accompanying drawings, in which drawings:
Fig. l is a plan view, with parts in section, of a paint roller embodying the invention.
Fig. 2 is an enlarged section taken substantially on the line 2--2 of Fig. 1.
Fig. 3 is an enlarged side elevational view showing one of the spanner bars and the end spring members in position.
Fig. 4 is an enlarged fragmentary detail of one end of the mechanism shown in Fig. 3, but rotated 90 degrees from the position shown in Fig. 3.
Referring now more particularly to the drawings, it will be understood that in the embodiment herein disclosed, the reference character I indicates a rod which is bent and rebent to form a handle portion 8, at the end of which is mounted a hand grip 9 and an axle portion II], on which is mounted the roller as hereinafter more particularly described.
The roller consists generally of a cylindrical member II which is preferably formed of layers of spirally-wound cardboard or other suitable material and which is covered with sheepskin I2 "7 Claims. (01. 154230) or .other suitable material which is capablemi absorbing paint and transferring it to .a flat surface which may becontacted by (the roller. The cylindrical member H is internally supported .at either end by means of end closure members 1.3.
each of which has inwardly projecting spring 'fingersM, the outer surfaces of which are con vexly curved in order to L'frictionally engage the inside surfaces of the tubular member "l'l.
The end members [3 are .held in spaced relation by means of a pair of spanner bars T5, the adj'a-' cent end of which overlap as shown. in Fig. 4.
Eachend member 13 (:Fig. 4) has a centralopenj in'g I6 and the overlapping ends of the spanner bars I 5 are provided with openings. as at ll;
whichopenin'gs 16 and T! are arranged to accommodate a bearing member l-B which has its inner end riveted over, as at V9, so that the end member It and the spanner "bars l5 are firmly flocked together to form a unitary assembly.
The assembly just described is he'ld against longitudinal displacement in one direction on the axle It by means of a stop member 20, which is crimped to the axle l0 and is held against longitudinal displacement in the opposite direction by means of a set screw 2|, which engages an internally threaded bore 22 formed in the end of the axle ll].
Having described my invention what I claim and desire to secure by Letters Patent is:
1. In a device of the character described in combination, a rod bent and rebent to form a handle portion and an axle portion, a roller mounted for rotation on said axle portion, said roller consisting of a tubular member covered ith a paint applicator surface, said tubular member being internally supported at either end by means of a spring closure member at the center of which is positioned a bearing member, and a pair of spanner bars secured to said end closure members and spaced radially inwardly from said tubular element and adapted to hold. said end closure members in spaced relation.
2. A paint roller comprising in combination, a rod bent and rebent to form a handle portion and an axle portion, a pair of end members rotatably mounted on said axle portion, spanner bars secured to said end members and arranged to hold said end members in spaced relation, each of said end members having axially inwardly extending spring fingers, and a cylindrical member covered with a paint applicator surface and frictionally engaged over said spring fingers.
3. The structure defined in claim 2, in which said bars have radially inwardly directed overlapping ends, the said overlapping ends having aligned openings, and asid end member having a central opening in alignment with said aligned openings in the ends of said spanner bars, and a tubular member in said openings, said last named tubular member having shoulders formed thereon adapted to secure said end member and said spanner members in interlocking engagement.
4. In a device of the character described in combination, a tubular member covered with a paint applicator surface, end members for said tubular member, said end members having a plurality of spring fingers thereon arranged to frictionally engage the inside periphery of said tubular member, and a pair of spanner bars secured to said end members and arranged to hold said end members in spaced relation, a tubular bearing member for each of said end members, said tubular bearing member extending through a central opening formed in said end member and openings formed in said spanner bars, there being shoulders formed at either end of said bearing member for locking said end member and the ends of said spanner bars in fixed position.
5. In a device of the character described in combination, a rod bent and rebent to form a handle portion and an axle portion, a roller mounted for rotation on said axle portion, said roller consisting of a cylinder member provided with a paint applicator outer surface and two end closure members disposed within the opposite ends of the cylinder member, each closure member having cylinder supporting portions extending axially inwardly from the end of the cylinder member toward complementary portions on the opposed closure member and tensioned outwardly yieldingly against the cylinder member, and spacing means extending between said end closure members holding them in spaced apart relationship.
6. In a device of the character described in combination, a rod bent and rebent to form a handle portion and an axle portion, a roller mounted for rotation on said axle portion, said roller consisting of a tube provided with a paint applicator outer surface and provided at either end with an end closure received within the tube and having axially inwardly extending tube spacing means tensioned yieldingly outwardly against the interior of the tube, said end closures rotatably mounted upon said axle portion, and spanner bars spaced radially inwardly from the tubeand from said tube spacing means and extending between the end closures to space the closures apart.
'7. In a device of the character described the combination comprising: a rod bent and rebent to form a handle portion and an axle portion, a roller mounted for rotation on said axle portion, said roller including a tube provided with a paint applicator outer surface and provided at either end with an end closure received within the tube and adapted to rotatably support the tube on the axle, said end closures provided with a plurality of axially inwardly extending tube supporting spring fingers tensioned radially outwardly against the tube along a portion of its length and adapted to grip the tube and prevent axial movement thereof relative to the end closures, and means extending through the tube and spaced radially inwardly therefrom and engaging the end closures to space them apart.
