PORTABLE PAINT MASK Filed Feb. 7, 1949 PORTABLE PAINT MASK 4 Samuel Wheatley, Kansas City, Mo. 7 I I Application February 7, 1949, Serial No. 75,001

3 Claims. (01. 91.65)

My invention relates to portable paint masks and my object is to provide a simple inexpensive and efficient device of this character which may be held in one handto mask a surface adjacent to'another surface being painted with a brush manipulated by the other hand f A further object is to protect the surface of the mask against the accumulation of paint thereon from the brush when in use, so that there will be no excess waste paint to drip or run from the mask upon the surface protected thereby.

Otherobjects will hereinafter appear, and in order that the invention may be fully understood, reference will now be had to the accompanying. drawing, in which:

Figure l is a perspective view of the device in position to protect a portion of the glass of a window sash, 1

Fig. 2 is a rear elevation of the device,

Fi 3.is a cross section of the device.

Referring in detail to the different parts, A designates a portion of a window sash including glass Band frame C. As shown by Fig. 1, my deviceis arranged to protect a portion of the glass B while an adjacent portion of the frame is beingpainted. Referring mor particularly to my device, 2 designates a blade of suitable size forming the masking portion of the device. The rear portion of the blade is firmly secured at its upperand lower ends to brackets v Al and 6 respectively, extending rearwardly at an angle from the blade as'shown best by Figs. 1 andf3. Mounted between the rear ends of the brackets is a manually controlled roller 8 which is preferably of rectangular' cross section as shown, .jlh roller 8 is provided at its upper and lower ends with axially aligned..;screws or pivots l and I2, extending freelyg through apertures in the rear ends of the brackets-4 and 6, respectively.

A roller I8, of cylindrical cross section, is mounted at its upper and lower ends upon axially aligned fscrews or pivots 2!] and 22 which in turn pass through apertures in offset portions 28 and 30 of the brackets 4 and 6, respectively.

The blade 2 is protected from paint by a sheet of paper 38 or other tough flexible material wrapped around the roller [8 in a}.-roll. As shown best byi'Fig. 3, the sheet 38 extends forwardly from the roller I8 along one sidejof the blade 2, then folds over the front edge of the blade and extends rearwardly' thereof to the roller 8, around which it is wrapped several times.

With'the sheet 38 arranged as'shown by Fig. 3, it is apparent that it fully coversthe front and rear sides ofv the blade 2 and thus'protects the 2 same from paint during the painting of the window sash A.

In practice, the rectangular roller 8 is grasped with one hand and the forward end of the blade 2 is placed against the inner surface of the sash A to protect the glass B as shown by Fig. 1, while the adjacent portion of the frame C is being painted.

During the painting operation, more or less paint will be brushed upon the exposed side of the sheet 38, which on becoming covered more or less by the paint, is manually wound upon the roller 8 as needed until the front side of the blade is covered with clean paper.

By making the roller 8 in rectangular form as shown and inserting flexible washers 42 and between the ends thereof and the brackets 4 and 6, sufficient friction is provided to overcome any tendency of the roller 8 to turn backward and allow the sheet 38 to become slack. Likewise, washers 45 and 48 may be inserted between the ends of roller l8 and the brackets 4 and 6 to prevent the paper from unwinding except when the roller 8 is manually operated to wind the paper thereon.

After the sheet 38 has been covered with paintthrough almost its entire length it is removed from the rollers 8 and [8, so that a fresh sheet may be substituted.

From the foregoing description it is apparent that I have provided a device which is well adapted for the purpose intended, and while I have shown and described a preferred form of the device, I reserve the right to make such changes and modifications as properly fall within the scope of the invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. A portable mask comprising a planar blade, a pair of spaced-apart rollers parallel to the forward edge of said blade and carried for rotation by said blade adjacent the rearward edge thereof, frictional means resisting rotation of said rollers, and a strip of flexible material having its end portions wound respectively on said rollers and its intermediatelportion lying against each side of said blade and passing around the forward edge thereof.

2. A portable mask comprising a planar blade, a pair of spaced-apart rollers parallel to the forward edge of said blade and carried for rotation by said blade adjacent the rearward edge thereof, and a strip of flexible material having its end portions wound respectively on said rollers and its end portions Wound respectively on said rollers.

and its intermediate portion lying against each side of said blade and passing aroundthe for ward edge thereof, one of said rollers being noncircular in cross-section, whereby" to serve as a 2,545,638 j y I 4 REFERENCES CITED The following references are of record in the file of this patent:
