PAINT BRUSH GUARD Y Filed Dec, 9, 1955 v mfszvroa John Mas/aney ATTORNEY United States Patent 2,820,237 PAINT BRUSH GUARD John Maslaney, Cadillac, Mich. Application December 9, 1955, Serial No. 552,137 3 Claims. (Cl. 15-248) This invention relates to a paint brush and more particularly to such guards for use in painting trim without getting paint on surfaces adjacent the trim. This invention is particularly adapted for trimming around the glass of a window or door.

It is extremely difficult for one not skilled in painting to paint the trim of a window or door without getting paint on the glass. In fact, it is difficult even for a skilled painter to avoid smearing the glass unless he exercises special care. The exercise of this special care is time consuming.

Various types of paint brush guards have been de veloped for painting trim or other fine work. However, none of these guards is completely satisfactory. The primary object of this invention is to provide an improved paint brush guard which can be secured to any paint brush enabling even an unskilled person to paint grim and other fine work without smearing adjacent suraces.

Another object of this invention is to provide a paint brush guard attachment having a guard part normally biased to operative position and easily retractable to inoperative position for replenishing the brush.

Still another object of this invention is to provide a paint brush guard having means for self biasing the guard into operative position and means by which the guard can be retracted with the same hand used to hold the brush.

A further object of this invention is to provide a paint brush guard attachment which can be used on different brushes with the minimum of difficulty.

Another object of this invention is to provide a guard of simple construction and, therefore, low in manufacturing cost. This guard has a minimum number of parts which are readily manipulated for attachment and removal to the brush.

Other objects of this invention will become obvious upon reading the following specification in conjunction with the accompanying drawings wherein:

Fig. 1 is an oblique view of the paint guard attachment in operative position on a paint brush.

Fig. 2 is another oblique view of the brush of Fig. 1 with the guard in retracted or inoperative position.

Fig. 3 is a plan view of the guard mounted on a paint brush showing the guard in operative position.

Fig. 8 is a fragmentary, plan view of a modified guard.

. Throughout this specification the word outwardly is guard attachment for a ice used and shall be taken to mean outwardly or away from the center axis of the paint brush.

Briefly, this invention is concerned with an improved guard attachment for paint brushes having a handle part adapted to slidably fit over the paint brush handle. The guard attachment has a guard part adapted to slidably fit over one face of the bristles of the paint brush. An intermediate part connects the handle and guard parts. This intermediate part has an elongated slot extending between the handle and guard parts and means secured to the brush, between the handle and the bristles, and extending through the slot for guiding the guard. A spring holds the guard part in operative position over one face of the bristles. This spring is preferably housed in a rib extending from the handle part. It is attached to the brush and the handle part providing means for biasing the guard part into operative position.

Referring to the drawings, reference numeral 10 denotes a brush having a handle 11 and bristles 13. 'The bristles 13 are secured to the handle 11 by the head 12. The brush 10 is of conventional design having the bristle part wider than the handle. Thus, the handle 11 tapers inwardly adjacent the head 12, forming shoulders 14.

The guard attachment, although fabricated as one piece, in reality includes three distinct parts: the handle part 30, the guard part 40, and the intermediate part or neck 51). The handle part 30 slidably nests about the handle 11; the guard part 40 covers one side of the bristles 13; and the intermediate part 50 connects the guard part 40 to the handle part 20.

The handle part 30 has a channel-like cross section (Fig. 7) and includes the flanges 31 connected by the bight portion or web 32. The flanges 31 extend downwardly along the sides of the handle 11 While the Web portion 32 extends over one face of the handle 11. The entire handle part 30 is of appropriate size and shape permitting it to slide longitudinally along the handle 11. A rib 33 extends outwardly from the Web 32. If made of metal, the rib is stamped out to form a' housing for the spring 63 whose function will be described more specifically hereinafter. A tongue or book 34 is struck from the rib into the housing forming an anchor for one end of the spring 63. The entire unit can be cast of metal or plastic, in which case the rib 33 and tongue 34 are formed in the mold.

The guide part 40 includes a plate having an arcuate cutout 41 on each side, intermediate its ends. At one end and toward the handle part 30, the sides of the plate are bent down along the sides of the bristles 13. This forms a channel in the guard part in which the bristles 13 slide when the guard is retracted or projected. The other end 44 of guard 40 is flared outwardly to project well beyond the sides of the brush. The extreme forward end 45 is bent downward. This entire construc-: tion permits only the extreme tips of the bristles to beexposed and allows painting right into a corner or up to the edge of the glass without getting paint on the. glass. A struck out thumb tab 46 projects outwardly from the web portion 43 of the channel formed by the flanges 42.

The intermediate part 50 forms a neck connecting the guard part 40 and the handle part 30. This intermediate part is fiat and narrower than either the handle part St) or the guard part 40. It is of sufficient length to permit the channel parts of the handle 30 and guard 40 to slide on the handle 11 and the bristles 13, intermediate part 50 has an elongated respectively. The slot 51 extending between the handle part 30 and the guard part 40. The

elongated slot 51 extends slightly into the guard part 40 (Fig. 3). Reinforcement ribs can be provided on each side.

The guard attachment 20 is secured to the paint brush t by the bolt 60 extending through the enlarged portion of the ha 1 1 brush, one end of the spring 64 is attached manner, the spring guard toward the end of the bristles 13, thus causing the cover one side of the bristles.

Operation and guard may be in When the person painting with the brush desires Both the brush hand.

It is obvious that this operation one hand thus relieving the other for helping No positive movement to move the guard part 40 to nected from hook 65.

It should be evident that this guard attachment is of simple construction.

The guard, neck, and handle parts can be accomplished in a single operation or in several successive operations. The bolt 60, screw 66, spring 64, and hook 65 are conventional elements. The guard attachment 20 can be molded of plastic or are preferred by many operators for trim painting because their shape facilitates painting in corners.

A brush equipped with this guard is not only usable for painting Him but has utility in striping operations or anywhere when one color is to be brought up to another.

It will be recognized that a screw may be substituted for the bolt 61. Like the bolt, it may be tightened to secure the guard in retracted position.

It should be understood that in describing this invention, preferred embodiments have been shown. Other various and diflerent embodiments can be made without departing from the scope of this invention. bodiments shall be considered to fall within this invention unless the appended claims note otherwise.
