This invention brush.

The general object of the invention is to provide an improved paint brush in which the bristle holding portion and the handle portion are mounted for movement relative to each other. a

A more specific object of the'invention is to provide a paint brush which has a head-mounted thereon in such manner: that it may be shifted to a position inclined to the axis of thehandle and may beheld in that position.

A further object of theinvention is to provide a paint brush including a handle with a bore therein and with a memberslidable in the handle and with a brush supportingreceptacle pivoted on the handle and 'shiftable by a memberin the bore for adjustin the position ofthe brush relates to arr articulated paint relative to the handle.

Other objects and the advantages of my invention will be apparent from thefollowing description taken in connection with the accom panying drawings,'wherein: Fig. 1 is a central, sectional view, showingan articulated paint brush embodying the features of my invention; I 4 s Fig. 2' is a longitudinal sectional view taken at right angles to Fig, l showing the brush;

' Referring to the drawings'by reference characters, I have shown my invention as embodied in a-brush which is indicated generally at In,

As shown the brush includes a handle I I made of wood, plastic or other suitable material. The

handle has a ferrule l2 mounted upon the upper 7 Claims. coma-172) range a metal 'brush -retaining collar ll which slides in the receptacle. The collar I! has bristles l8 suitably 'securedthereln. The receptacle and collar "areprovided with aligning beads l9 and I 9' which serve. to holdthe collar in the ferrule. In thebottom of thereceptacle I arrange a hole 20 which'is aligned-with the bore [3. The shank 2| of an eyermember 22 extends through the-hole 283. The shankv 2| is bent at its upper end as. at 23 to form a head portion which is arranged upcn the bottom l6 of, the receptacle and is. held in place ,as by Welding at 22.

Within the bore I3..I ;arrange an operating member 24 which at its upper end is bent as at 26 and then is reverselybent to form a portion- 21 which is engaged in theaperture of the eye 22. Remote fromthe portion!!! the handle end is provided with atslot 28 and with a larger slot 29 arranged outwardly from the slot 28. In the slot 291 arrange a nut 30 which is shown as rectangle and as held in place by'a sleeve 3|. A ferrule 32 is arranged on the handle about the slot 28. The lowerv end of the operating member 24 is reduced as at 33 to provide a shoulder 34.

On the reduced portion 33 and engaging the shoulder 34 I arrange an actuating member. 35 which is threadedas at 36 to engage the threads on the nut 35. Beyond the threads the operating member isprovided with a finger grip portion 31. The operating member portion 33 receives a washer 3B and is riveted as at 39 to hold the parts assembled. In operation-when the brush is in position shown in Fig.2 the operator rotates the portion 31; thus axially moving the member 24 and causing the portion 21'. thereon to push the eye member upwardly asi'nl ig. 3 so that the brush is tilted. flhe brushwill remain in the tilted position. and-in this position is particularly adapted for painting on the under sides of various structures: -The applicant's brush is particularly ,useful in shipyard work where all exposed metal 'must-be painted and wherein much of the painting is done in places which are quite -;inacce ssible to astraight brush.

In.Figs'.- 6 and show amodification of my .inventionwhereinthe. brush is indicated gen-. erally at andincludes a brush portion 5! and a handle 52.; The'handle is provided with a central bore53 in which 'I show a tube or sleeve 54. The, lower end of the sleeve is provided with slits which-provide apair of jaws -66. The portion-adjacent ,to'theslit 65 is provided with taperingthreads 61.

a bottom I6. Within the brush receptacleI are 5.5 Theupper end. of thebrush is provided with a ferrule 68 which extends beyond the end of the handle and supports a hinge 69. The hinge 63 engages a receptacle which is similar to the receptacle M previously described. In the receptacle I mount collar 1| similar to the collar El and this collar supports bristles 12. An eye member 13 passes through a hole 14 in the bottom of the receptacle 10 and is engaged by a hook member 15 on a rod I6 which slides in the tube 54. Agasket 16-is arranged on the end of the handle and is engaged by the bottom of the receptacle when the brush and handle are in axial alignment. 7

The lower end of the rod is shown as provided with a finger grip portion 11. The threaded portion Bl is engaged by the tapered threads 18 on a thumb nut 19 and the construction is such that when the thumb nut is tightened the jaw 66 will engage the rod 16 and will hold the rod in adjusted position. The construction is such that when the finger grip portion is moved up or down it will cause the receptacle 10 carrying the brush to be shifted from one position to another. Tightening of the thumb nut 19 will hold the brush in the adjusted position.

In Figs. '8 and 91 show a modification of my invention wherein the brush is indicated gener' ally at Bil. In this modification I provide a handle 81 which has an oifset portion 82 at one' end. This offset portion is provided with an aperture 83 through which a pintle pin 84 extends. The pintle pin 84 engages a projecting portion 85 which is mounted on a receptacle 86 similar to the receptacles previously described. The receptacle 86 supports brush 81. The pintle pin 8G is provided with a head 88 and washer 89 at one end and at the other end with a thumb screw 90. When the thumb screw is loosened the receptacle 86 may be turned about the axis of the pintle pin after which the thumb screw 90 may be tightened to hold the brush in the desired position.

From the foregoing description it will be apparent that I have invented a novel articulated paint brush which is simple in construction, easy to adjust and efficient in its operation.
