MMUAL PMN'TING MACHINE.

Application filed July 28, 1922. Serial No. 577335.

To all whom it may concern: Be it known that I, EDWARD Gor'rmn'n, a citizen of the United States, residing in New York city,in the county of New York, State of New York, have invented certain new and useful Improvements in Manual Paintin Machines, of which the following is a fu 1, clear, and exact description of the invention. My invention relates to improvements 111 manual painting machines or machines for cleaning preparatory to painting, having movable members to spread the paint or clean surface to be painted; and the objects 1 of my improvements are, first, to produce a hand-guided painting machine with which a person can paint very much faster, and bet ter than, and with more convenience, than with a plain paint brush, or any palnting machine previouslyinvented, and the fundamental, basic idea I use to accomplish this is to construct a brpshwhose length is greater than its width, said brush to have mechanical'means for moving bristles composing the brush, (constructing a brush of any h without the width bec0m-- desirable len ing bulky ai s greatly in the rate of spreading paint, under various conditions, and a thorough system of distributing the paint uniformly over the entire length of brush,

regardless of the length gives my painting machine the great advantage of delivering an even coat of paint to the surface to be painted) second, to produce a brush of the revolvable member type of any desirable length without the width becoming bulky, so that the area to be painted, or cleaned, or prepared to be painted will be' covered quickly. For purpose of illustration I wlll .pick some. particular cases, suppose the s1de of a ship, or a large flat wall is to be painted, in this case it may be desirable to use a brush 12" or 15". long and about 2" wlde, but if the interior of a room is to be painted sirable to construct a brush of any desirable shape to fit thisparticular object, and from the accompanying drawings and specification it is readily seen that my brush can be adapted to any shape. (as before stated in trolling the supply of paint; fourth, to pro when in any part of this patent application 1 it may be desirable to'use a brush 5" longis to be painted in quantity it will be dev conjunction with this long brush of small width, are means for moving the bristles composing the brush so that the linear speed of the moving bristles is in excess to the linear speed of a man moving an ordinary paint brush, this aids greatly to the speed of spreadin the paint); third, to provide for a brus. of the character mentioned manually operated means for con- 35 vide for a brush of the character mentioned means of rotating revolvable members; fifth, to provide for a brush of the character mentioned means of spreading the paint uniformly; sixth, to have a brush as light as possible sothat it can be readily handled and thus aid to the convenience of spreading the paint, and from accompanying drawings it will be seen that I accomplish thisby the use of a flexible wire drive to the brush, so that the driving mechanism to op-- crate the revolvable member is external to the brush; seventh, means to prevent brushes of the revolvable member type from throwing paint centrifugally. one embodiment of my invention is illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the-views, (and refer to the brush or the painting brush it must be understood to mean the entire portion of the painting machine that is held in the hand, see Figure 5 of the accompanying drawings, when I refer tovthe rotating brushes I will always add some modifier to indicate same, as the small brushes,v rotatary brushes etc.) and in which- Figure 1 is a front view of a machine containing a preferred form of my invention; Figure 2 is a vertical section taken on the line AA; Figure 3 is a longitudinal section taken on the line BB; Figure 4 is a view of the back of the machine with cover 76 01K and Figure 5 is a perspective view of a hand holding the painting brush in the same position as when brush is in operation. This figure also shows paint supply line, air supply line, and small brush rotating line.

The brush consists of a number of small brushes 1, 2, 3, 4:, and5, which are longer than wider as shown, and which are held to the small brush seats 6, 7, 8, 9, and 10 by means of small springs 11, 12, 13, 14, 15, and 16. The small brushes 1, 2, 3, 4, and 5 1 are readily detachable so that when they are worn out, they can be easily replaced by new ones. These small brushes have little pins 17, 18, 19, 20, 21, and 22 projectin out of the backs and engaging in holes in t is small brush seats, helping to hold the smallbrushes in place. The small brush seats are fastened to gears 23, 24, 25, 26, and 27. These gears are of the shape shown in accompanying drawings and have bearings in the brush body 28.

These gears mesh with each other and are so timed that the attached brushes are at right angles to each other. When the small gear 29 turns, it will rotate gear 25 in a certain direction, and in turn gear 25 rotates gears 24 and 26 in the opposite direction, and these in turn rotate gears 23 and 27 in the opposite direction to themselves. It is simple to understand that because the attached brushes are at 90 from. each other, and since they are longer than wider as shown on accompanying drawings, and since adjacent gears turn in opposite direc tions, the attached brushes will not interfere when rotating, and at the same time their painting areas will overlap. By using a difi'erent number of brushes, as 2, 3, 4, etc. the brush can be made any desirable length without the width of the brush be coming bulky. Small gear 29 is driven by a flexible wire 30, which some prime mover 31 drives at the other end, (as an electric motor,

till

or air motor) This flexible Wire runs 1nside of a stationary flexible tube 31. It, is desirable to make both the tube and wire in sections, say 6 feet long, coupled together, so that for any particular job the length can be convenient. A. shaft 32 of the small gear 29, has a bearing and coupling 33, and another hearing at the other end 34.

There is a stationary fringe oil brush 35 to catch any paint that might be thrown centrifugally by the small rotating brushes. This stationary fringe of brush 18 held to the brush body 28 by means of straps 36, 37, 38, and 39, and also by a number of ins 40, and 41. This fringe of brush is rea il'y detachable so that when it gets worn out from service, it may be replaced by new ones.

The pipe 42 leads the paint from. a i aint supply to the brush. lit is preferab e to have the paint under pressure so that there is a ready flow. @ne convenient method of getting paint under pressure is to have a paint can 43, having an air tight cap 44, which can be removed and can lled partly with paint. The cap 44 is then put on again and a hand air pump isconnected with the one way valve 45. It is very easy to raise the pressure inside of the paint can so that the paint will flow readily. Tt is advisable to have a filter 46 to catch any dirt or lumped paint which may be in the paint.

To control the paint as it enters the brush,

newness there is a valve 47. When the valve is open the paint flows up pipe 48 and into the main ipe 49 inside of the brush. This main pipe has smaller pipes 50, 51, 52, 53, and 54, branching oil to supply paint to each of the small rotating brushes separately. There are small valves 55, 56, 57, 58, and-59 in each of these branch pipes so that the amount of paint can be regulated for each small brush separately. The paint'supply pi cs 50, 51, 52, 53, and 54 terminate in nozz cs 60, 61, 62, 63, and 64. These small pipes run inside of larger pipes 65, 66, 67, 68, and 69 which are for compressed air and which terminate in'nozzles also. The aint nozzles are inside of the air nozzles, this construction helps to draw, atomize and spray the paint against the surface to be painted, thus insuring a more even spread of paint. These larger pipes for the air are branches from the main pipe 70, which is supplied with compressed air from pipe 71 in which is a regulating valve 72, and leads via pipe 73 to a compressed air supply 75.

There is a back cover 76 on the brush. Each gear 23, 24, 25, 25, and 2? must be lubricated at the bearings, and for this purpose grease cups 77, 78,79, 80, and 81 are necessary. Each gear has a small hole 82 to allow some grease to flow down and lubri cate the contact between the moving gear and the stationary large air pipes. It is advisable to bind the three pipes together 83, for convenience as shown in Figure 5.

The operation of the painting machine is as tollowsz-The. brush is held in one hand, and with the other hand the operator starts the prime mover, which transmits its rota- ,tion via the flexible wire to the small rota table brushes. Then with the free hand the operator opens the air valve 72. The small brushes are now rotating and the air flowing, then the operator puts the brush against the surface to be painted. He next opens the paint valve 47, with his free hand, and starts painting, by passing the brush over the surface to be painted. The small valves 55, 56, 57, 58 and 59 are adjusted so that the paint is spread evenly. Due to the speed of the small rotating brushes the linear distance covered in a given time by each small brush is very great, when compared with the Ill) aavassa pharacter described, abrush composed of a number of small rotatable brushes so arranged and so constructed that each others painting area overlaps, thus forming a long brush of small width; a brush having apaint supply to each small-rotatable brush, individually controlled by separate valves; hollow gears and hollow-small brushes to permitthe paint supply to be lead to the front of brush, the ends of the paint supply pipes in the small rotatable brushes to be equipped with nozzles so that the paint under ressure' is forced against the surface to e painted; a compressed air supply rotate wine external to brush; and a brush having astationary fringe of brush enclosing small rotatable brushes to catch paint thrown centrifugally by the rotating brushes.
