(Cl. -144) l i s claims.

This invention relates to a paint brush and particularly to a handle therefor.

In painting various parts of a ship, equipment and appliances installed thereon, it has been found out that some of the surfaces which are partially hidden behind other parts, equipment and appliances, cannot be reached by an ordinary brush. Various means have been tried in connection with a brush to reach said inaccessible surfaces, but they proved to be inadequate.`

It is the object of this invention to provide an articulated telescoping handle for a paint brush, or the like, which ,can be extended in length and the adjoining sections of which be set at an angle to each other, so as to get around an obstacle and reach a surface hidden therebehind. d

Other objects and advantages will appear as the specification proceeds and the particular features of the invention will be specifically pointed out in the appended claims.

The invention is illustrated in the accompanying drawing in which:

Fig. 1 is a plan view of the brush.

Fig. 2 is a longitudinal cross-section of the brush, some parts being shown in elevation.

Fig. 3 is abottom view of the brush.

end of the the ap- In detail, my invention comprises a brush element I and an articulated telescoping handle 2. The brush element I has hair 3 imbedded in a metal holder 4 having a narrow neck 5 terminating with a ball 8.

The. handle 2 has on its front end a hall socket 3 consisting of an upper member I0 and a lower member Il, both members being held together by a bolt I2 and a wing nut I3. The surface of the ball 8 and the inner surfaces of the socket 9 are keeper I4. For the purpose of illustration, the

handle 2 is shown in the drawing as having'- three sections, I5, I6 and I1, although it may have any number of the same without departing from the spirit of this invention. d

The section I5 has on its Vfront end the upper member I0 of the socket 9,` which member is J shown as made integral with the same. The rear ward each other. The keeper I4 is closely fit preferably made rough to prevent the relative Y movement `oi the ball to the socket when the wing nut I3 is tightened up. 'I'he ball 6 and the socket '8 form a universal joint for the brush element I so that the latter may be placed into any angular position in relation to the handle 2.

The handle 2 consists of plurality or sections which are enclosed, with freedom to slide, in a end I8 of said section is reduced in thickness to one-half thereof and is rounded. The front end I9 of the section I6 is also reduced in thickness to one-half and both ends 4are connected by a pivot I5 and passes through a hole 22 in the end I8. The top of the pivot 20 is threaded and carries .a nut 23 thereon to hold both ends together. The section 'I5 may be turned about the pivot 20 in any angular position in relation to the section I6.

Means is provided to interlock said sections in angular position, said means consisting of a small embossment 25 on the lower surface of the end I8 which fits in any one of the corresponding indentations 26 formed circumferentially on the upper surface of the end I9. v'The section l5 is turned around the pivot 20 to a desired position and until the embossment 25'fits into one of the indentations 26, whereupon the nut 23 is tightened up, thus holding both sections in fixed position.

The section I6 is connected with the section I1 in exactly the same way. The rear end 21 of the section -II is connected with the keeper I4. The latter is preferably made in form of a channel with a. bottom 30, two sides 3|, each sidehaving its upper portions 33 bent at right angle t`oaround the sections I5, I6 and i1,`but the latter may be easily moved in and out of the ilrst.

The section I1 and the keeper I4 are connected by a bolt 34 which passes through a hole 35 in the end 21 of said section and a. slot 36 extending through the length of the bottom 30 oi said keeper. -A nut 31 is provided on said bolt 34 to hold said section and keeper securely together.

The front end of the keeper I4 is rounded and i the upper surface thereof is provided with a plurality of indentations 3B each of which is adapted to accept an embossment 39 formed on the lower side of the end 21 and to secure the section I1 in an angular position in relation to the keeper I4. It shall be noted that the sides 3i of the keeper I4 are cut of! near its front end to enable the section I1 to swing about the bolt 34 at an angle more than 180.

The handle 2, including the sections I5, I8 and 20, which is afiixed to the center of the end In operation, the brush is used as an ordinary brush with the sections I5, I6 and I'I in contracted position as shown in Fig. 1. Whenever it is necessary to extend the handle ofthe brush, the nut 31 is unscrewed and the sections I5, I6 and I 1 are pushed forward a desired distance and the nut 31, is tightenedI up. I1' necessary, one or more sections may be given an Vangrular position. For that purpose the nuts 23 are unscrewed. the sections are turned around the bolts 20 into a desired position and the nuts 23 are tightened up. The sections may be pushed in extreme forward position as shown in Fig. 7 and given angular lpositions s'o as to permit the brush element I to get around an obstacle, such as a pipe 40. As is well known, certain pressure is applied upon a brush during painting. But in spite of such pressure the sections and the keeper will preserve their relative positions due to interlocking of the sections, as well as of the last section I1 and the keeper I4, by means of the embossments 25 and 39land the

indentations

26 and 38 respectively. The brush element I may also be given any angular position in relation to the section I due to the universal joint connection therebetween.

Fig. 8 shows a modied form of my invention in which a separate brush element 50 having hair 5I embedded in a holder 52 is enclosed in a brush retainer 54 and securely held therein by means of bolts 55 passing through said holder 52 and,

retainer 54. The retainer 54 is connected by means of the neck 5 to the ball 6 oi' the universal joint between the brush element and the articulated telescoping handle as it has been described in detail heretofore. T he advantage of the latter arrangement is that when the brush element I is Worn out it is easily substituted by another one, or when a brush of a different shape, or size, is desired, the proper brush element is readily inserted in the brush retainerv 54 and the brush is ready for immediate use.

Having thus described my invention, I claim:

1. A brush comprising ya brush element, and a handle comprising a plurality of pivotally connected sections, a universal `ioint between said handle and the brush element, means at said pivotal connections and said universal joint to tighten the same in selected angular positions, a keeper adapted to slidably receive said sections when the same are in axial alignment,l slidable means connecting the outermost section to said keeper to hold said last mentioned section in engagement with the keeper in all positions, and to tighten said connection therebetween.

2. A paint brush comprising a brush element, a handle and a universal joint therebetween, said handle consisting of a keeper and plurality 0I sections pivoted to each other and slidable therein, said pivoted sections being adapted to form an extension of said handle and to assume angular positions in relation to each other and to the keeper.

3. A paint brush comprising a brush element,

a handle and a universal Joint therebetween, said handle consisting of a keeper and a plurality of sections slidable in said keeper, each of said sections having an end reduced in thickness, and pivoted to the end of an adjoining section means in each of the adjoining ends for interlocking the same in angular positions to each other.

4. A paint brush comprising a brush'element, a handle and a universal joint therebetween, said handle consisting of a plurality of sections pivotally connected to each other and'adapted to take vangular positions in relation to each other, means for interlocking said sections, means to tighten said sections in said angular positions and a keeper adapted to slidably receive said sections.
