13 Claims. (Cl. 91-625) 1 This invention relates to new, and useful improvements in paint applicators and the primary object of the present invention is to provide a roller including means operatively connecting the latter to a source of fluid toregulatfe a flow of fluid to, the roller so that the latter may be used to paint surfaces without the necessit'yof placing the latter into a paint container.

Another important object of the present invention is to provide a paint applicator embodying novel and improved valve means for con- Referring now to the drawings in detail, and more particularly to Figures 1-6 inclusive, wherein there is disclosed a preferred embodiment of the present invention, the n eral l0 represents ia shank provided with a s bstantially U-shaped integral extension 12 at one end. Journalled on the free end of this extension is a roller l4 com prising a cylindrical core'l6 and an absorbent sleeve I8 secured to the outer periphery'of the trolling a flow of fluid from a source to the roller mechanism. I

A still further object of the present invention is to provide a paint applicator including a feed.

chamber so designed as to permit the same to be quickly and readily emptied or cleaned.

A still further aim of the present invention is to provide a paint applicator that is simple and practical in construction, strongand efllcient in use, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same isv intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which: I

Figure 1 is bottom plan view of the present paint applicator;

' Figure 2 is a side elevatlonal view of Figure 1, and with parts broken away and shown in section;

Figure 3 is an enlarged longitudinal vertical sectional view taken substantially on the plane of section line 3-3 of Figure 1, and withparts of the fluid conduit broken away and shown in section; f

Figure 4 is a transverse vertical sectional view taken substantially on the plane of section line 44 of Figure 2, and with parts thereof broken away and shown in section;

Figure 5 is a transverse vertical sectional view taken substantially on the plane of section line 5-5 of Figure 2, and with parts broken away and shown in section;

Figure 6 is a transverse vertical sectional view taken substantially on the plane of section line 6-6 of Figure 2;

Figure 7 is a fragmentary longitudinal vertical sectional view showing the valve means for the core. At the opposite end .of the shank is providedahandle 2|).v

Adjustably embracing a portion of the roller 14, is an arcuate, transverse a shield 22 having end flanges 24. This shieldis provided with a transverse. aperture 26 that 'co mmunicates with an aperture 28in a casing 30 and further comrnu'ni cates with the outlet opening 32 in a hollow feed chamber 34. It is preferred, that the shield, casing and feed chamber be integrally formed.

However, the elements may be separate parts suitably secured to each other without deviating from the scope of the present invention}.

Fixedly secured to substantially the center of chamber 34, is one end of a substantially cylin drical valve housing 36 that communicates with one end of an angular feed tube or fluid conduit 38.

Receivably engaging the free openend'of' the housing 36, is a packing gland 40 in which is slidably'mounted a needle valve '42. v The inner end 44' of the valve'42 is preferably pointed to engage a conical bore or seat 46 provided in the fixed end of thehousing communicating with chamber 34.

Pivotally' mounted as at 48 on the conduit 36 is the bifurcated end 49 of' a lever or trigger 50. This lever is removably secured adjacent its free end to valve 42. The outer free end of the lever is disposed at a convenient location relative to the handle 20. A transverse recess 52 is provided in the upper portion of casing 30 and receives "a transverse bar 54 substantially trapezoidal in cross-section,- that is pivotally mounted on pins 56 carried by the casing. This bar 54 constitutes a valve for controlling opening 26 in the shield. Spring arms 58 carried by the casing 30 bear upon the outer face of bar 54 to normally retain the same in a positon for closing opening 26.

In practical use of the device, the conduit 38 is coupled to the outlet'line 60 leading from a source of fluid such as a paint pressure tank or the like (not shown). When the lever 50 is pulled by a finger toward the handle 20, the pointed end of the needle valve is disengaged from its normal tight fitted position in seat 46 to permit a flow of fluid into chamber 34. As'the pressure of amass:

- through openings 28 and 2 to enga e the absorbent sleeve ll 01' the roller. When lever II is released, spring 2 embracing the needle valve and biased between the packing gland ll and a retaining ring 64 mounted on the needle valve. will carry the pointed end 44 of the needle valve again into seat 46, preventing a flow oi fluid into the chamber 34.

It should be noted, that the housing 3! and the conduit 38 are retained or supported in position totheshank lllbyuseoipairsofarms removably secured to each other and having their arcuate terminal portions 68 formed to embrace the periphery of the shank, the conduit and the valve housing. These arms may be adjusted for positioning of the shield relative to roller ll.

For the purpose of removing any fluid remaining in the chamber 34 and for cleaning the inner surface of the chamber 34, there are provided nipples II at each end 01 the chamber that receivably engage closure cap 12.

Reference is now directed to Figures 7 and 8. wherein there is disclosed a valve means for 'controlling opening 26 in the shield 22 in slightly modined form. In this embodiment, a transverse groove or channel 14 is. provided in the inner periphery of the casing 30 and engages the enlarged edge or beading 16 of a plate 18 constituting a valve within the opening 28 of'the casing for regulating opening 26 in the shield. The ends of the plate 18 are pivoted to the ends of the casing by a pm or tne like 80 on which is fixedly secured oneend 01! a link 82; The free end of the link a2 is connected to a coil spring 84 carried by the outer face of chamber 34 to normally retain the plate in a closed position relative to opening 26. This plate is so designed as to be actuated or pivoted forwardly as the fluid passes from the chamber to contact the same. However, the plate will not allow fluid to pass from the shield into the chamber.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
