STATES PATENT 2 Claims.

The purpose of my improvement is to provide a light portable device suitable for painting ceilings and walls of buildings, which device con-.

tains both means to apply paint and a supply of paint for that purpose.

Another object of my invention is to provide a device of simple construction and a few parts, in such a combination that they do not get easily out of order.

A further object of my improvement is to provide a machine including means for control of its operation, particularly with respect to means of applying paint to the surface to be painted.

I shall now describe my invention with reference to the accompanying drawings, in which:

Fig. 1 is a perspective view of the whole machine, with some parts being shown in less than full relative length.

Fig. 2 is a diagrammatic view of the machine with respect to the surface to be painted with the aid 'of' said machine.

Fig, 3 is an end view of the upper part of the machine shown in Fig. 1,inc1uding a tank for paint, with an end wall thereof removed to show parts within.

Fig. 4 is a perspective view of a drum, being a part of my machine.

Fig. 5 is a side elevation of a detail of my machine.

. Fig. 6 is a front elevation of the upper part of my machine, this being the side 'to face the wall to be painted.

Fig. '7 is the top view of a tank, which is a part of my machine.

Similar numerals refer to similar parts throughout the several views.

The machine consists generally of a tank It, designed as a receptacle for liquid paint, a roller ii mounted above the tank, and an elongated shank 92. Tank i0 is cylindrical in shape and open at one end, for which end a removable cap i l provides a closure. Normally, the tank is disposed in a horizontal position. Its cylindrical wall is open at what is. normally its upper side. The opening i3 is substantially rectangular, as shown in Fig. '7, and extends substantially the whole length of the tank. Axially disposed within the tank is a drum 14. The latter is mounted for rotation around its axis in a spider. I5, which is made of a band of metal or suitable material. The band runs along the surface of drum I l, as shown by numeral l6, turning up at both ends to provide bearing ii for axle it of the drum and spreads apart into a V-formation I8, each leg. of said v-formation being bent. inwardly over the surface of drum It, the bent over portions forming short extensions i9. These serve as anchorage points for elastic skimmers 20, preferably made of rubber. The skimmers are in close proximity to the surface of drum It. The radial distance of extensions 59 and member I 6 from axle 46 are such that said extensions and the band fit closely against the inside surface of tank It) and are in a frictional contact with said surface. Said extensions is are intended to straddle the longer sides of opening it, as-

shown in Fig. 3.

Mounted above opening E3 in tank 10 is a roller The roller is hollow, its outer surface being covered with a textile material of the kind used for conventional rollers employed for painting walls, and includes an axle protruding at each end. At one end, the protruding part of the axle fits into a slot 23 in a bracket 2! extending radially from the end wall of tank l0. At the other end, bracket 22 rises from the upper surface of tank in adjoining opening i3. With the ends of its axle in slots of respective brackets, roller H is mounted right above said opening l3, which is somewhat longer than said roller H, said roller abutting frictionally the surface of drum it within tank iii.

The machine includes means whereby the contact between the drum within tank 10 and the roller I iv may be discontinued should it be so desired. The means are controlled by a trigger adjacent handle 25. Said means include a lever made of one continuous length of wire. The wire is made into a loop 30 at one end of the roller so as to enclose the end of axle 2t, turns parallel to the axis of said roller running within bead iii, to a point mid-way the length of tank ill, extends at right angle to said axis in a curve 32 approximately following the outline of tank l0, makes a hairpin turn 33 and returns upwardly to form a symmetrical counterpart, terminating in a loop to enclose the other end of said axle. The lever so made is fulcrumed in said beads 3| on both sides of shield 65, arching over the wire where it starts on its downward curve 32.

The tank it is held in a cradle composed of semi-circular bands 25. The bands are heldhi a spaced relation by prongs 28 of shank it, made of two parallel wires 25, anchored to handle 25. A trigger 36 held between the ends of band 21 by means of pin All and including a finger-piece M, is connected to a rod 35 running between wires 26, and forms at its outer end an eye 36. The latter encloses the hairpin turn 33 of the lever fulcrumed in. beads ti. A Spring 31 coiled around said rod 35 is at one end afflxed to the rod. At the opposite end, it bears against a crossmember 8!, binding together said shank wires 26. The cross-member contains an aperture 39 for sliding passage of said rod 35. A screw 42 in an upright lug 48 on handle 28, is used to regulate the extent of the movement of trigger 38.

I shall now describe the manner in which my machine may be used; First, cap 44 is put into its place and a quantity of liquid, paint is poured into said tank through opening i3. To gain access to said opening, the roller I! must be shifted upwardly, away from contact with drum it within the tank. This shifting may be done manually or indirectly by means of trigger 88, as will be hereinafter described. With the tank properly filled with paint, the machine is held in an upright position at an angle to bring the roller ll into contact with the wall to be painted. As the machine is pushed upwardly, or pulled downwardly, the roller, being in frictional contact with the wall, is made to rotate. Because the roller is also in a frictional engagement with the drum, the rotation of the roller causes the rotation of the drum. As the latter is immersed in liquid paint, it gathers, in the course of its rotation, a quantity of paint on its surface and brings it upwardly to feed said roller II. Excess quantity of paint is brushed off by skimmers 20. The remaining quantity of paint is picked up by the surface of roller II and is applied to the surface which is to be painted.

, If in the course of the operation it is desired to app y the roller to the surface to be painted, but to discontinue the contact of the roller with the paint supplying drum, this may be eflected by the action of the trigger it. As the trigger is pulled by means of finger-piece 4!, eye 34 of rod 35 pushes down-the lower end of the lever which controls position of roller II, and causes loops 3! to rise upwardly and to remove said roller II from contact with drum M. This is shown in Fig. 3, where the position of roller H away from aasaeoa drum I4 is shown in dotted lines Ha. when the finger-piece 4| is released, the roller, under the action of coiled spring 31, returns automatically to its normal position. that is, into contact with said drum M.

It is obvious that some changes may be made in the construction of my machine without departing from the inventive principle disclosed herein. What I, therefore, wish to claim is as follows:

1. A machine of the kind described, comprising a cylindrical tank for liquid paint, the tank being open at upper side, a bracket mounted on the tank at each end thereof, and extending radially therefrom, each bracket being provided with a slot therein, radially disposed with respect to said tank, a roller for application of paint to the surface to be painted, said roller being disposed over said opening and being mounted for rotation in said brackets by means of its axle, extending at each end into the respective slot, a drum axially disposed within the tank and being in a frictional contact with the surface of the roller to be rotated by the rotation thereof, a handle to support the tank, and lever means extending from said handle to the axle ends of the roller to discontinue the frictional contact between the roller and the drum.

2. A machine of the kind described, comprising a tank for liquid paint, the tank beingopen at its upper side, a roller mounted horizontally over said opening on its axle ends in brackets having downwardly extending slots therein, a paint supplying drum mounted for rotation within the tank, parallel to the roller and in frictional contact with its surface, to be rotated thereby, lever means applicable to the roller to lift said roller above the drum, to discontinue frictional contact therewith, and means to support the tank with the roller thereon for operation.
