cylindrical handle 1 is employed which has an exteriorl'y threaded neck 6 formed with a conical threaded opening 7. A follower 5 is frictionally engaged within the cylinder 1 so as to be held against rotation, 40 and is slidable by meansof a threaded rod 4, the threads of which engage the follower. Rod 4 has a fin er enga ing head`3 to rotate same and also as a co lar .3*l engaging the outer end of the cylinder t0 prevent longiof the neck 6.

tudinal movement of the rod. The bristles 10 are set in a head 8a which latter is enlarged at its inner end and provided with a curved chamber 8 the outer end of which latter is of circular form and interiorly threaded to enga e with the exterior threads ucts 9 are formed in the head and extend from the chamber 8 through the central part of the upper side face of the head, as depicted in Fi res 2 and 3. A cover 1l isfprovided fbi* the bristles, the latter having an inner circular neck formed to engage with the circular part of the head 8a and to lie flush with the periphery of the cylinder 1 and abutting the 'inner en of the latter.

By removal of the head 8a and the cover 1.1 from the neck 6, a tube 12 of paste, may be secured to the neck 6, by threading of its neck 12*7l into the threads 7 of the cylinder neck 6 the threads being of conical form so as to accommodate paste tubes having threaded necks of diferent sizes. Opening a in the cylinder permits air to enter the cylinder in back of the follower.

The neck 6, the head 8a land the cover 11 are formed so that the head and cover will engage the inner end of the cylinder 1 and the cover will lie flush with the yperiphery of the cylinder 1.
