PAINTING APPLIANCE OF THE DETACHABLE ROLLING SLEEVE TYPE Filed Aug. 14, 1950 2 Sheets-Sheet 2 FIG.5.

Fl 6.9. 10 mmmunnmmn INVENTOR By EARL E.THOMAS ATTORNEY Patented Apr. 20, 1954 UNITED STATES TNT OFFICE PAINTING APPLEANCE OF THE DETACH- ABLE ROLLING SLEEVE TYPE 6 Claims.

This invention relates to painting appliances of the type equipped with a detachable rotatable sleeve from which paint may be applied to a Work surface by rolling the sleeve along such surface. The invention may be considered an improvement on the subject matter of my United States Patent No. 2,520,863, issued August 29, 1950.

An object of the invention is to simplify and reduce the cost of a painting appliance employing a detachable rotatable paint-applying sleeve, by eliminating the usual expansible and contractible roller, and mounting said sleeve upon a pair of spaced heads journaled on the shaft of said appliance.

Another object is to equip said spaced heads with spring chucks suited to enter and be compressed by the end portions of the sleeve and to frictionally grip the sleeve by their expansive reaction.

Another object is to provide sleeve-mounting members carried by and bridged between said chucks.

Another object is to adapt one of said heads to form an end abutment for the sleeve.

Another object is to rotatably mount on the shaft of a painting appliance one or more elastic disks for frictionally retaining a paint-applying sleeve on such shaft.

These and various other objects are attained by the construction hereinafter described and illustrated in the accompanying drawings, wherem:

Fig. 1 is a front view, in partial section on the line l! of Fig. 2 of my improved appliance, showing the detachable sleeve in use position on the appliance.

Fig. 2 is a top plan view of the same, omitting the sleeve.

Fig. 9 is a fragmentary axial sectional view of the appliance, employing another type of expander.

Fig. 10 is a cross sectional View, taken on the line ltit of Fig. 9.

Referring now in greater detail to the construction shown by Figs. 1 and 2, the reference character I designates a shaft formed by one end portion of a rod, whereof the other end portion forms a shank 2 inserted in a handle 3 disposed transversely to the shaft, said rod having a gooseneck portion 4 joining the shaft and shank. Rotatable on the shaft, at its free end is a circular head 5, preferably a sheet metal stamping, such head peripherally forming an annular flange 5a projecting toward the gooseneck end of the shaft. Said head is restrained from axial sliding, jointly by a collar 6 press-fitted on the shaft and by a headed screw 1 set into the shaft. Near its juncture with the gooseneck, the shaft journals a second sheet metal head 8 held from sliding by collars 9, and of a diameter somewhat exceeding that of the head 5. A pair of substantially U-shaped spring chucks I0 have their respective yoke portions Ina welded or otherwise fixed centrally on the respective heads 5 and 8, the jaws of each chuck projecting toward the companion chuck and having a slight relative divergency in so projecting. Detachably mounted on the two chucks and frictionally retained thereon is a sleeve comprising a quite stiff inner member ll formed preferably of iibrous material, and an outer covering l2 having a suitable paint-retaining nap or pile. Lambs wool or felt exemplify materials suited to form the outer covering. The members H and 12 are adhesively or otherwise permanently interconnected as a unit. The spacing of the free end portions of each pair of spring jaws l0 predeterminedly exceeds the outside diameter of the head 5, so that the sleeve ll, l2 may be freely slipped over said head and still effect a deflection of said jaws, adapting the latter to frictionally maintain the sleeve in place under any stresses normally arising in use of the appliance. The free ends of the spring jaws are bent slightly toward the shaft, as indicated at Hlb, avoiding any tendency of such ends to resist sliding of the member H. In its applied position, the inner end of the sleeve abuts thehead 8, the two heads closing the sleeve ends and excluding paint from the sleeve interior.

The construction shown in Figs. 3 and 4 conforms to preceding description with exception that bridging strips is rigidly interconnect the legs of the two spring chucks I00, the main length of said bridging strips being sufficiently spaced from the shaft to frictionally interiorly engage the sleeve H, [2 and mount the latter. Said strips are transversely arcuately curved to conform to said sleeve.

The modification appearing in Figs. and 5, journals a pair of sheet metal heads [4 and Ma on the shaft, respectively adjacent its free end and its gooseneck connection, such heads having peripheral annular flanges projecting toward each other. said heads are adapted to be slipfitted in and form closures for the extremities of a sleeve H, 12. Said sleeve is frictionally held in place by a pair of rubber or like resilient disks I5 rotative on the shaft and spaced from each other and from the heads l4 and Ida. As illustrated, sleeves iii are loosely mounted on the shaft to exercise the desired spacer function.

The construction illustrated in Figs. 7 and 8 differs from that of Figs. 5 and 6 in that the disks 15 are each replaced by a rotatable chuck comprised of two cupped members it disposed back to back and formed with oppositely projecting peripheral jaws 18, which diverge slightly from the axis of the chucks in receding from the latter. The extremities of said jaws are inturned toward the shaft to have clearance from the sleeve H, I2. Sleeves l9 and |9a hold the checks properly spaced apart and from the heads it and Ma.

Figs. 9 and 10 disclose a construction patterned after that of Figs. 5 and 6, except that the disks l5 of the latter figures are replaced by coiled wire springs 20, each comprising at least one convolution, and each having a radial end portion 2!, looped centrally of the spring to rotatively mount the spring on the shaft.

The described construction, in its various forms, saves material and achieves increased lightness by using relatively small and compact spring chucks in place of the sheet metal rollers heretofore required as a mounting for the paintapplying sleeve.

1. An appliance for painting and like operations, comprising a shaft having a free end, a sleeve detachably mounted on the shaft and formed by a stiff inner tube and a cover for such tube having a paint-retaining pile, ahead journaled on the shaft substantially at its free end, forming a closure for the corresponding end of the sleeve and freely fitting within the sleeve, a

second head journaled on the shaft remotely from said free'end and endwise abutted by the sleeve, and a pair of spring chucks respectively carried by the respective heads and each having jaws inserted in and contracted by the sleeve and expansively reacting a to frictionally grip the sleeve, the sleeve being manually slidable along its axis to engage it with and disengage it from the chucks.
