4 Claims, 13 Drawing Figures AND TRAY ATTACHMENT My invention relates to new and useful improvements in painters tools and, more particularly, to a novel combination roller pan and tray for use with a paint roller, the combination roller pan and tray being optionally mountable at either side of a ladder or at the front or rear of the ladder.

A primary object of the invention is to provide such a painters device which can be easily tilted orangularly adjusted while in situ on the ladder, for better paint utilization and for easier draining.

FIG. 11 is an exploded view in perspective of a third and the preferred form of the device showing the relationship of the paint tray boss and locking device, the latter being associated with the side rail and rung of a ladder; I

FIG. 12 is a sectional view online 12 12 of FIG. 11; and

FIG. 13 is a view of FIG. 11.

Referring first to FIG. 1, a form of the device is indicated by 10 and is shown in cooperative association with astep 12 of astep ladder 14.

The device includes atray 16 for paint having a roller pan orplatform 18 fixed to the forward edge thereof for supporting apaint roller 20.

A grille-likefalse bottom 22 is disposed intray 16 and is held in spaced relation to the bottom of the tray by such aslegs 23, (see FIG. 7), disposed at each side thereof, which legs may be fixed to the false bottom as shown, or may be hinged thereto to permit adjustment. The legs are preferably formed from spring steel so that the false bottom can be urged downwardly under pressure and will return to a normal level when that pressure is released. I

The false bottom allows uniform paint application around the entire roller circumference and provides a traction drag. Without it, a heavy solution of paint builds up on one side of the roller circumference, wherefore the roller tends to rotate to that side and to spread the paint unevenly. It also acts as a baffle to help in bottom plan of thelocking device 2 prevent excessive splashing when the device or ladder are moved. It retards surface skin drying on the paint by deflecting surface air currents over the top and by holding moisture or paint fumes in the still air found between the paint and platform. Finally, it suspends the,

roller out of the paint when the roller is not in use, thus preventing the roller from falling and submerging itself in the paint.

Apouring spout 24 is formed centrally of aforward lip 26 on roller pan orplatform 18 to facilitate draining of paint.

Apot'hook 28 is suspended from the platform for holding such as apaint pot 30.

Abrush holder 32 is releasably fixed to the side of the platform for holding apaint brush 34.

Alignedbosses 36 extend horizontally outwardly from each side of the platform adjacent the forward end thereof, the bosses being cooperant, in the FIG. 1 embodiment, with ahook member 38 which is releasably engageable with one of thesteps 12 ofladder 14.

Twobosses 36 are provided so that the device can be mounted along either side rail or stringer 40 of the ladder.

Hookmember 38 includes a flat body portion'42 adapted to rest on the upper surface of the step and having ahook portion 44 at its inner end for engagement with the inner edge of the step.

Aweb portion 46 extends upwardly frombody portion 42 along the central longitudinal axis thereof, the web portion having a through-hole 48, (see FIG. 2), therein adjacent the end thereof opposite fromhook portion 44.

'Ribs 50, which extend outwardly from each planar face ofweb portions 46 adjacent through-hole 48, are selectively engageable inserrations 52 provided in the outer free ends ofbosses 36.

Alip 54 on the lower face ofbody portion 42 functions as a stop to preclude movement of the hook member out of engagement with the step of the ladder.

Athumb screw 56 has a threadedshank 58 which is engageable in a tappedopening 60 in the end of eachboss 36, theshank 58 of the thumb screw passing freely through through-hole 48 inweb portion 46 ofhook member 38, with ashoulder portion 62 of the thumb screw being brought into bearing engagement with the web portion.

A tappedopening 64 is provided in the head and shoulder portion of the thumb screw in order that a threaded extension, not shown, may be threadedly engaged with the thumb screw, such an extension being desirable when the device is hung inside of or to the rear of the ladder.

A tappedopening 66 is provided inweb portion 46 ofbook member 38, aset screw 68, (see FIG. 2), being threaded therein and extendable therethrough into anaccurate slot 70 in the end of eachboss 36, the set screw acting as a secondary stop in the event theribs 50 on the web portion become disengaged from theserrations 52 in the bosses. Anannular recess 71 is provided in the face ofshoulder 62 onthumb screw 56 to provide clearance for setscrew 68.

The paint tray and platform may be tilted to any desired position of adjustment by loosening the thumb screw and set screw and then retightening same to lock the'tray and platform in position.

In FIG. 8 I have shown the device of FIG. 1 in cooperative association with a rung 12' of an aluminum ladder 14', theplatform 18 of the device being shown in a tilted position for draining paint.

The device of the invention of FIG. 9 is identical to that of FIG. 1 with the exception that a modified form ofhook member 138 is employed for engagement with arung 12" of awooden ladder 14".

As seen in FIGS. 9 and 10,hook member 138 includes aflat body portion 142 having ahook portion 144 at its inner end for engagement with therung 12".

A pair ofweb portions 146, 146 extend upwardly frombody portion 142 along each edge thereof, the web portions having aligned through-holes 148, (see FIG. 10), therein adjacent the end thereof opposite fromhook portion 144.

Ribs 150, which extend outwardly from the outer planar faces of eachweb portion 146adjacent throughholes 148, are selectively engageable in theserrations 52 provided in the outer free ends of thebosses 36.

Anelongated shank 158 of athumb screw 156 passes freely through the through-holes 148 and is receivable in the threadedopening 60 in the end ofboss 36.

Tappedopenings 166 are provided inweb portions 146 ofhook members 138, aset screw 168, (see FIG. 10), being threaded therein and extendable therethrough into theaccurate slot 70 in the end of eachboss 36, the set screw acting as a secondary stop in the event theribs 150 on the web portions become disengaged from theserrations 52 in the bosses.

As with the FIG. 1 embodiment, the paint tray and platform may be tilted to any desired position of adjustment by loosening the thumb screw and set screw and then retightening same to lock the tray and platform in position.

In the form of the invention shown in FIGS. 11-13, thebosses 36 of the device are receivable in acam locking member 80 inserted into the hollow rung 12' of aluminum ladder 14' and extending outwardly from the side rail or stringer 40' of the ladder.

Cam locking member 80 includes a-flatbody portion 82 havingbrackets 84 depending therefrom at its opposite ends, the inner bracket being of appropriate size as to be freely receivable in the rung in the manner of a slip fit.

Acam rod 86 is joumalled at its ends inbrackets 84 and has an offsetcentral portion 88 adapted to be moved into locking engagement with the interior wall of the rung as shown in FIG. 12, such being possible because of the ecentric or off-center pivotal mounting of the ends of the cam rod in thebrackets 84.

An actuating handle fixed to the cam rod inwardly of one of thebrackets 84 facilitates movement of the cam rod.

A sleeve orsocket 92 extends outwardly from one of thebrackets 84 and is of appropriate size to receive thebosses 36 therein in free sliding manner.

Anabutment 94 depends from the lower surface ofbody portion 82, thecentral offset portion 88 of the cam rod being adapted to bear thereagainst as the cam rod is rotated to the several positions as indicated in dash lines in FIG. 12. When the cam rod is rotated to the left as viewed in FIG. 12,central offset portion 88 is moved into ever tighter bearing relation to the inner wall ofring 12. When the cam rod is rotated to the right, the offset portion is moved out of engagement with the interior wall of the ring wherefore the cam locking member may be repositioned relative to the rung or removed therefrom.

Bosses 36 are telescopically receivable into sleeve orsocket 92 and are locked in position by aset screw 96 extendable through aslot 98 in the sleeve orsocket 92 and threadedly engageable in one of a pair of tappedopenings 100 provided in eachboss 36.

A bracket orwasher 102 may be disposed between theset screw 96 and socket orsleeve 92 for better locking action.
