The rollers I0 comprises an outer cylinder I9 of aluminum or other sheet metal, Bakelite or other plasticvmaterial molded or pressed to the proper thickness or gauge desired. Ihe inner cylinder 2U fits snugly within the outer cylinder I9 so as to frictionally maintain its position when adjusted' longitudinally thereof and as the outerl cylinder. {Both cylinders are provided with rows ofl holes, the holes in the outer cylinder being designated 2| andthose in the inner cylinder being designated 22 and the holesvof each cylinder being similarly rows are alternately disposed in staggered relation thus providing means through which the paint mayI pass evenly and uniformly throughout the surface of the roller while at the same time reducing the number of holes required to cover` the entire area. The ends of the inner cylinder are provided with inturned

annular flanges

23. Disks or

heads

24 and 25 close the ends of the outer cylindervto turn with the roller and for this purpose are preferably provided with miters or

rabbets

26 to receive the ends of the outer cylinder and have

end flanges

21 projecting outwardly of the periphery toform a stop or shoulder to retain a tubular knitted or woven cloth covering 28 therebetween and against axial movement. This covering may be of tubular weave or form or a sheet with its ends or abutting edges woven together and is preferably of some textile or cloth material which is a good paint carrier and applying surface or transfer means. For this purpose, it is preferably of cotton or cotton and wool, permeable and porous,

the warp and weft threads thereof forming a series of openings or perforations in open work formation and arranged diagonally or in rows normal to each other as desired or according to the surface finish to be produced. The disks forming the heads or

ends

24 and 25 are provided with

central bearing holes

29 to receive and turn on the shaft or axle I I. The

disk

24 is provided with a threaded bore 39 sealed around the shaft by a packing 3| and a nut or

gland

32 engaging the bore 30 so as to prevent the escape or leakage of paint at this point around the shaft. The extremity of the shaftV Il is provided with a threaded counter-bore 33 which takes a screw 34 having a

flat head

35 fitting in a counter-bore or recess 36 in the

disk

25 with an interposed

packing

31. Thus the leakage of paint around the shaft and between the same and the disks is prevented at both ends of the roller.

The inner cylinder is provided with an apertured boss or

lug

38 on the

flange

23 at one ond and means is provided between the ends of the cylinders or between one disk and the adjacent end of the inner cylinder for shifting the inner cylinder axially so as to bring the holes thereof in partial or full registration or entirely out of registration so as to close the holes and prevent the passage of paint therethrough. For this purpose a reduced portion 39 of a screw 4U extends through the aperture of the

lug

38 so as to freely turn therein and is thereby swiveled to the inner cylinder and held by a collar 4! pinned or otherwise keyed thereto. A

wing

42 is pivoted to the opposite end of the screw so as to be turned into a

recess

43 in the disk at that end and has threads 44 engaged in the threads of a

hole

45 in said disk. By this means, turning of the screw will serve to adjust the inner cylinder longitudinally of the outer cylinder and roller so as to Vary the degree of registration or size of the openings and thereby permit regulation of the amount of paint passing to the covering or paint applying surface. Of course, it is to be understood that any other suitable means may be provided for shifting the inner cylinder or either one of the cylinders such means being engageable through one end wall or a head and with the adjacent end wall or head of the other cylinder to shift one cylinder with respect to the other. In other words, this arrangement may be reversed or the adjusting related and disposed so that the holes of adjacent screw or shank may slide in the outer cylinder. In either event', the

recess

43 accommodates the wing or

pivot key head

42 which serves as a finger piece for turning the screw in obtaining the desired adjustment.

Means is provided for causing the inner cylinder to move axially or to prevent relative rotation of the cylinders and for this purpose the inner cylinder may be formed of a single rolled sheet instead of a solid tube of which the outer cylinder is also preferably made and is provided with spaced

longitudinal flanges

46 formlnga slot slidably receiving a key or rib 41 extending inwardly from the outer cylinder. .By having these flanges and the groove or guideway formed thereby as well as the rib extending longitudinally, the movement of the cylinders relatively is longitudinally or axially of the rollerand the inner cylinder, which in the .preferred form is shifted relative to the outer cylinder, will be guided straight so that the holes will accurately maintain their arrangement relatively. Also, by having the inner cylinder formed of a split tube or spring sheet whether of metal or plastic and tending to normally expand, the inner cylinder will be frictionally held in adjusted position within the outer cylinder irrespective of the adjusting or operating means such as the adjusting

screw

40. A stop or

cotter pin

48 is disposed through a diametrical aperture in the shaft H adjacent the

disk

25 to prevent longitudinal shifting -or translation of the roller on the shaft or the shaft relative to the roller and particularly the outer cylinder thereof.

In order to provide means for filling the 'cylinder with paint, the disk or head at one end, preferably the

disk

25, is provided with a filling

opening

49 which is closed lon vthe inside by a springI valve including a

plate

50 of spring metal suitably attached to the inner surface of the disk as by screws 5| and carrying at its free end and on its outer surface a disk 52 which enters the

opening

49 and normally closes the same. By this means, a tapered spout represents at 53 of a dispensing can with a funnel spout, may be passed into the

opening

49 to unseat the valve as shown in Fig. 8 of the drawings so as to fill the roller with paint. This spout may have a shoulder or stop 54 to limit the displacement thereof within the opening and the degree of unseating of the valve so that the spring metal thereof will not be bent excessively. A

guard

55 is also provided to prevent the paint spattering, dropping or being thrown from the roller in use. It preferably consists of a plate which may be curved as shown to lie closely adjacent or in proximity to the applying and transfer surface of the roller to help smooth out the same and insure a uniform distribution and a smooth application of the paint to the surface. However, the absorbent covering will normally be uniformly saturated so as to evenly distribute the paint in applying the same and therefore the guard plate may be swung away from the roller or in any desired spaced relation relative thereto and hold by mounting

clamps

56 by which one longitudinal edge of the plate is attached to the supporting portion i3 of the handle as previously described. The clamps are held by

screws

57 so that the guard or plate may be retained in any desired adjusted position relative to the roller. In order to prevent the free edge of the guard from catching in the woven or knitted material of the covering, the free edge thereof is preferably turned or Iiared outwardly 2,325,807 -as indicated at 58 but this is only necessary when the plate is in contact with or in close proximity to the roller covering instead of being swung outwardly in considerable spaced relation relative thereto. In any event it will be seen that the covering will be uniformly saturated with the paint which Will be evenly distributed not only along the entire length of the covering but also will be uniformly applied to the surface being treated. By varying the mesh or weave of the covering, any desired ornamental eiect or iinish may be produced in addition to a smooth finish, such as a rough or stippled iinish. This may also be varied by manipulation of the device. In addition, by having the handle bent around one end of the roller, the other end will be free to pass up to a given line or to get into corners inasmuch as the end of the roller or the edgeof the outer cylinder may enter the extreme point of the angle into -which the device is disposed in painting or decorating the same. Also, it is to be understood that the device is not limited in its use to paint, but may be applied to other similar materials.

It should be noted that the heads or

disks

24 and 25 closing the ends of the roller are ilush with said ends instead of being spaced from said ends or seated within the roller or outer cylinder and of course, the

flanges

21 may be omitted so that the covering 28 will extend to the outer faces of said heads. Also, it should be noted that the textile covering 28 may be of single or multiple ply as shown in Figs. l, 3 and 4. An enlarged detail of this covering is shown in Figs.

9 and 10 in which the covering is of double ply being formed of a tubular material folded on itsclfso that the interstices or spaces between the cords or threads of the Woven material form substantially circular, oval or other shaped openings which may determine the nature of the finish produced upon a surface. If the

guard plate

55 is in contact with the covering as shown in Figs. 2 and 3, the paint will be smoothed out and this will tend to so eiect the application thereof to the surface in addition to causing more uniform' distribution in connection with the particular arrangement of holes or perforations in the cylinders as previously described. However, under normal circumstances the holes will cause even distribution and uniform application and so the guard plate may be moved outwardly in spaced relation to the roller and covering thereof and frictionally held by the clamping means upon the supporting portion I3 of the frame or handle thus preventing the paint from spattering, dripping or being thrown upon the user or extraneous objects. Obviously this guard plate may be flat, angular or of other shape than the curved formation shown.

If desired, when making up the device in small sizes especially for small surfaces or places or for use in crowded or irregular places, angles or corners, the inner cylinder of the roller may be omitted andsince the size of the holes may .be varied whether one or two cylinders are employed, they may be made of a. size to pass just suicient paint, varnish or other coating as needed to give the best results. Since the inner cyiinder is not found necessary under such cir-` cumstances, the omission thereof and its function together with the adjustment means is considered well within the scope of the invention and in such case the

screw

40 is disconnected from the inner cylinder but used to close the threaded aperture or

hole

45, or a suitable plug may be substituted for this purpose. Also, the covering will control the supply or transfer of the paint especially in multiple, double or two-ply form as shown and described although a single ply will be suiiicient if of proper gauge or thickness and soft as described. In addition to smoothing the covering and the paint thereon and insuring uniform saturation of the distributing covering along its entire length and therefore uniform application, all surplus paint will be removed by the guard plate when against the roller. As distinguished from a brush head where the paint usually hardens around the bristles the present device can be readily cleaned with a solvent such as turpentine, and maintained in proper usable condition. Also, it is to be understood that the

screw

40 may be threaded intothe inner cylinder at the

lug

38 and swiveled in the

head

24. In the form shown the

screw

40 and the

fingerpiece

42 are in when the holes 2| and 22 are in alignment as shown in Fig. 1 and it is only vwhen the holes are closed or partially closed that the

screw

40 and the iingerpiece or

wing

42 are out and the offsetting of the portion I2 of the handle will permit the same to clear the iingerpiece. However, by having the screw swiveled in the

head

24 it will not move longitudinally but its threaded connection with the inner cylinder will cause the latter to be adjusted to secure any degree of opening and passage of the paint to the covering.
