12 Claims. (Cl. 91-65) This invention relates to the art of painting closed by a cap 10. In the bearing, there is wheels and has 4particular reference to the rotatably received the shaft 12 having the bore painting of the felly. 14. Y

I In prior practice where it is desired to paint yAt its forward end, the shaft l12 terminates in l 'f-- the elly with a paint having a different color an enlarged iiange 16 provided with the studs 68 than'the paint on the spokes, it `has been cus- 18 which t into the bored portions 20 of a tomar'y to wrap paper around the'y spokes and holder 22. The holder has a stepped bore 24 then spray kthe felly with the usual paint gun. in which there is received the plunger 26.

The present invention aims to promember 38.

A spring 46 is 75 has a central ring member provided with slid-l conned between the head 34 and nut 44 and a able-'radiating l*fingers torwhich are attached second spring 48 is confined between the. nut semi-cylindrical covering members which exand the shoulder at the end of the stepped bOIe tend over the spokes. -A similar mask is placed 24- The Springs 46 and 48 are for the pul'POSe 25 on the opposite side of the Wheel and has semiof resiliently holding the masks andv wheel on 80 cylindrical covering members 'which mate with the mount.

1 and 2. wardly of the mask 55 or 56. Referring to the drawings, the numeral 2 i'n- Secured to the end of each clip 72 by means dicates asuitable upright mounted" on the hoor of the rivets 80 is a semi-cylindrical covering v an'dhaving aswiveled head 4 at its end. The' member 82, which extends'over and covers' the y head has'thebearing 6 and the oil groove' 8 spokes 54. The en'd or tip of ea'ch covering 1119 member 82 adjacent the felly 52 is provided with a plurality of buttons or projections 84 which strike against the portion of the felly immediately adjacent the spokes. The purpose of these projections is to allow the paint from the paint gun to reach the portions of the telly very close to the spokes. The springs 74 have their ends 86 contacting with the ends of the clips 72 and constantly urge the covering members 82 toward the spokes when the masks are in position.

The inner mask is secured to the flange 88 formed on the mounting member 22. The flange 88 has recesses formed therein at spaced apart points slidably to receive the head ofva stud or rivet 90 secured'to the ring 58as vat 92. The ends oi the recesses are closed by the cap 94 and a coil spring 96 is mounted between the head of the stud 9U and the cap and resiliently urges the stud away from the flange 88. The purpose of thisconstruction is to form a flexible and resilient support for the mask, to assure a tight tof the mask on the wheel, and to allow for slight inaccuracies in workmanship. rEhe outer mask 56 is similarly mounted on a cup-shaped holder or retaining member 98 and is held thereon by similar studs 90 and springs 96.

A swingable hookV 100 is pivotally mounted on the holder 98 by means of the rivet 102, the hook end of which is adapted to be swung into and out of engagement with the neck 40 and head 42. This is clearly shown in the full and dotted outlines in Figure 2. f

The holder member 98 has the annular flange 104-which corresponds to the flange 88 on the supporting member 22. Both of these flanges are provided with annular or conical cam surfaces 106 which act on the ends of the fingers 66 to press them outwardly against the tension of the resilient bands "78. This action occurs when the masks are on the wheel and are held in place by means of the head42, hook 100 and the cam 28 and its associated mechanism. These cams will force the covering members 82 against the inner periphery of the felly 52 and thereby assure the covering of the spokes adjacent the lfelly to prevent the access of paint` to the spokes.

The covering members 82 are constructed so that they overlap slightly at their edges as shown at 108 in Figure 1. One of thecoveringmembers 82, preferably. the inner underlapping one, has secured thereto angle irons 110. The purpose of these irons is to limit the overlap of and to prevent the two covering members from contacting with the vspokesat their innermost ends. lThe angle irons are secured suchaslby welding at 112 and the flange 114 thereof vis adapted to receive the yend of the overlapping covering member 82. n

Ifjdesired, a rubber head 116? on a stud 118. se.- cured Yas at 120 to the retaining member 98, may be usedf' to positionY the mask 56. The head 116 ts in the opening 20 in .the wheel. f TheA operation voithe ,device is as follows: assumingthat there is nowheel on the mount or holder 22, the operator takes a wheel 50 and places it on the mount.v The mask 55 is already in place and the spokes 54 lof the'wheel arel fitted into the covering rmembers 82. .The outer mask 56 is then positioned on the wheel with the lcovering members 82 positioned over the spokes and overlapping the covering member 82 of the mask 54. The hook 100 is then swung into engagement with the neck 40 and the cam 28 then swung from the full line position to the dotted line position of Figure 1. This Will draw the retaining member 98 inwardly against the tension of the springs 96 and also depress the springs 96 of the inner mask 54. The cams 106 will at the same time come into action and force the fingers 66 radially outwardly to force the covering members 82 tightly against the inner periphery of the felly The notches or buttons 84 now will be tightly pressed against the felly and the device is ready for the paint gun. The paint is now sprayed on the interior of the felly and the wheel rotated at the same time. After the painting operation has been completed, the cam 28 is swung to the full line position which will allow the hook 100 to be swung free of the neck 40 and permit the renewal of the outer mask 56. The wheel may now be taken from the mount and a new wheel inserted.
