This invention relates to improvements in.

paint brushes and the invention comprises a brush having removable bristles secured" within a casing in spaced relation thereto in order that drippings fromthe :brushimay be collected within the casing and prevented from passing onto'the handle which is very objectionable. The invention further .-com e prises means for mounting the bristles Within the casing in order that the same may I have a certain degree of movement rela-' tive to the casing. This feature is par-V ticularly advantageous, due to the fact that the bristles are'moved from one side over a surface to be coated so that thepaint will be more readily retrieved and"a" large area of the brush bristles will bepresented to the surface being'coated. It is proposed to form the'bristles for use in connection with a brush by placing the bristles in a row upon a flat surface and binding one edge or end of the bristles between strips of cloth or fabric by means of stitching and subsequently vulcanized or rubber set 7 whereby the bristles will be anchored between the binding material. 1

The primary object of this invention is to 7 provide a paint brush having the above characteristics and in which the bristles are removably secured in removable sockets detachable from the brush housing or paint collecting casing.

A further object of this invention is the novel means employed for retaining the bristle sockets in normal spaced relation from the overturned edges of 'the'paint col-- lecting casing and at the same time allow free swinging movement of the bristle sockets relative thereto. It is to be understood that a spring or other resilient member may be employed for accomplishing this purof the casing to the other while being moved socket into the handle which may be made of a soft material to allow ample compression.

Other objects and advantages of the invention will become apparent during the course of the following description forming a partof this specification and in which,

Figure 14 is a bottom elevation of the bristle strips as shown in Figures 12 and 18.

In the drawings wherein for the purpose of illustrating the invention and wherein like reference characters will be employed to designate like parts throughout the same, attention is directed to Figures 1 to 3 inclusive wherein the reference character 5 will generally be employed to designate a handle formed of wood or other suitable material. The handle 5 is curved in the usual manner to form an easy gripping surface. One end of the handle is reduced as at 6 for receiving a socket member 8 rigidly secured to a casing 9. The casing 9 is of a flaring construc tion and is provided with an offset 10 extending around the side walls of the casing 9 and from the point designated by the reference character 10 to the opening in the casing 11, the casing is more or less straight sided which terminates in an inwardly projecting lip 12.

The casing 9 may be secured to the handle 5 by means of bolts or rivets 13. Movably mounted within the casing 9 is a bristle socket support 14 which is of a somewhat ovalshape configuration and which is pivotally secured within the casing by means of bolts 15 passing through the curved ends thereof. It will be noted that the bolts 15 are provided with a flat head and have a plainbearing surface 16 for freely rotating the bearing in the casing 9, while the free ends of the bolts 15 are threaded into suitable screw threaded openings in the bristle support 14.

Mounted within the vertical supports 14 are a plurality of bristles 17 which may be formed in the fashion illustrated in Figures 12 to 14 inclusive by sandwiching the bristles 17 between opposite strips of fabric or other suitable material and stitching the fabric 18 and the bristles 17 by stitchings 19 whereupon r a bristle strip is provided Which may be placed within the bristle support 14 and held therein by an inner locking ring 20. The locking ring 20 is provided with an annular flange 21 which engages one edge ofvthe bristle strip 17 and tends to hold the same in place relative to the bristle holder 14. It will be now seen that the bristles 17 may move to and fro within the casing 9 on the pivot 16 and it is proposed to normally hold the bristles 17 in a spaced fashion by means 7 of a leaf spring 22 which has one ofits ends secured between a spring clasp 23 mounted on the closed wall of the casing 9. It will be noted that the opposite end of the leaf spring 22 is secured to the bristle retaining ring 20 by having alternate strips 24 secured to inner ring 20 by means of rivets 25. In this fashion, the bristles 17 are always retained in spaced relation relative to the opening in the casing 9 except when the brush is in use whereupon the bristles are moved from one .Attention is directed to Figures 4 to 6 inelusive, wherein is illustrated a modifiedform of the invention and wherein the reference character 5 will generally be employed to designate a handle similar to the handle 5 illustrated in Figures 1 to 3 inclusive. In the construction illustrated in Figures 4 to 6 inclusive, the casing 9 is more elongated than the casing 9 is order to accommodate a larger number of bristles for covering larger surface areas such as walls or the like. The casing 9 is also provided-with an offset annular portion 10 and the side walls continue to the opening 11 in a more or less flared fashion as at 12.

The bristle supports disclosed in Figures 4 to 6 inclusive, comprises an inner bristle supporting ring 13, the side walls of which are bridged by struts 14 formed integral therewith and interposed between the intermediate sections of the struts are screw threaded cylinders 15 having internal screw threads as at 16' whereby bristles 17 may be provided with screw threaded thimbles adapted to correspond with the screw threaded cylinders 15. The inner bristlesupporting ring 13 is provided on its curved end with opposite bosses 18 which are adapted to aline with corresponding bosses 19 formed in the casing 9 at the juncture or annular flared portion 10'. Pivot pins 20 pass through suitable openings in the bosses 19 and the pins are provided with bearing surfaces 21 which terminate in reduced screw threaded portions 22. The screw threaded portions 22 may be screw threaded into corresponding screw threaded openings in the bosses 18 ofthe bristle retaining member 13 as clearly illustrated in Figure 6.

A series of bristles 17 are somewhat similar to the bristles shown in Figures 12 to 14 inclusive and may be retained in the bristles supporting member 13 and the lower edges of the bristles may rest against an annular flange 23' formed integral with the bristle support 13. An outer retaining ring'24 is then placed over the strip of bristles 17 in order that the same will clamp the bristles tightly in place and it is proposed to swage or bend one edge 25 of the outer retaining ring 24 over the edge of the annular flange 23. i

It is to be noted that the handle 5 is secured to the socket member 26 on the casing 9 by placing the edge of the socket into the handle 5 so that the handle will be frictionally held in place and prevented from moving.

Attention is now directed to Figures 7 and 8 wherein is shown a still further modified form of the invention and wherein the handle 5 is identical with the handle shown in Figures 4 to 6 inclusive and the brush casing 9" is provided with a socket member 10 which has its open end or edge swaged as at 11". The socket 10 is secured to the casing 9 by means of rivets or the like 12".

It will be noted that the casing 9" disclosed in Figures 7 and 8 is of a different construction than the casing illustrated in Figures 1 to 6 inclusive and in which the side walls are more or less straight and terminate in an overturned lip 13' thereby providing an opening 14" for the movement of the brush bristles. The bristles 17 are of a similar formation as disclosed in Figures 12 to 14 inclusive and have their ends anchored in a channel ring 18 which is provided with spaced spring lugs 19" adapted to be secured to the inner walls of the casing 9 by screws 20 or the like. In the construction illustrated in Figures 7 and 8 the casing 9 is provided with a spring clip 21 similar to the retaining clip 26 described in Figures 1 to 6 inclusive.

Figures 9 and 10 show another form of the invention in which the bristle support is immovable and the device includes a handle formed after the fashion of a hand grip, one end of which is secured in a socket 51 by swaging the edge of the socket as at 52. A

screw threaded projection 53 is formed integral with the socket member and said proj ection passes through an opening in the re stricted portion of a circular casing 54. The

casing 54 is provided with an annular offset portion 55 extending in flared walls 56 the edges of which are bent over as at 58 to the opening 57. The bristles of the brush 59 are secured :to a bristle holder 60 whi'ch'has an enlarged portion 61 and areduced portion 62 which is threadedon the screw threaded extension 53 for holding the parts in their as 64 and the'bristles59' in place.

A central set of bristles 66 may be secured to the bristle support 60 by anchoring the bristle ends in a thimble 67 which is removably secured to the bristle support 60 bymeans of a screw 68.

In Figure 11 is shown a still. further form of the invention and the handle 50 is of the same construction and shape as the handle shown in Figures 9 and 10 at 50. Secured to the handle 50 is a socket member 51 by swaging the edge thereof into the handle as at 52.- An extension 53 having screw threads is formed integral with the socket'member 51 and the extension is adapted to pass through an opening in the reduced portion 54 oi a cylindrical casing similar to the casing shown in Figures 9 and 10. The casing 54 is provided with an annular extension 55 whichtermlnates in flaredside walls 56 after the fashion shown in Figures 9 and 10. The

bristle support 60 is provided with a projection-61 to which is secured one end of a coil spring 62 and the opposite end being secured to the boss 55 within the confines of the reduced portion 54 of the casing. The extension 53 isthreaded into vthe boss 55 serving'to hold the parts including the socket and the casing in their assembled position. Bristles are provided for the bristle support 60" and it is proposed to employ the same type of bristles as shown in the several ligures, particularly Figures 12 to 14 inclusive.

It is to be understood that the forms of the invention herewith shown and described are to be taken as preferred embodiments of the invention and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-joined claims.
