Specification of Letters Patent.

Patented Nov. 28, 1911.

Application filed January `17, 1911. Serial No. 603,062.

To all whom 'it' may concemr l l Be it known that I, FRANK W7. DoMALsKI, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reservoir-Brushes, of which the following is a specification.

M y invention relates to magazine or reservoir brushes, and has for oneof its objects to generally improve the construction of brushes of the type to which the invention relates.

Other and further objects of the invention will readily become apparent to persons skilled in the art from a consideration of the specification taken in conjunction with the drawings, wherein- Figure 1 is a longitudinal central section of the device; Fig. 2 is a transverse section taken on line 2 2 of Fig. 1, showing the )referred form' FiO. 3 is a similar view* taken on line 8-3 of Fig. 1; Fig.v 4e is an enlarged top plan view of the fiat back brush proper, showing the attaching means secured to the brush back; and F ig. 5 is a crosssectional view of a modificati on, showing the brush back to be semi-circular in cross-section.

ln all of the views the same reference characters refer always to similar parts.

My brush consists essentially of two principal parts, the brush proper 5 and the reservoir 'or magazine (3. intended to contain substances such as soap, cocoa butter, or the like, which is to be applied' and distributed by the bristles of the brush. The reservoir 7 is preferably made of a sheet metal cap closed at one end and screwethreaded, as at 8, at its open end, to receive a screw-threaded closure 9. The closure is provided with a central perforation through which a screw-threaded feed rod 10 passes. A piston, 11, carries a screwthreaded nut, 12, which makes threaded engagement with the feed' rod 10. The rod carries a thumb key or button 13, secured therein as by pin 14, by which said rod may be rotated. A collar 15 is secured as by pin 16 to the rod so that the rod may not be withdrawn through the perforation in the closure. The rod and nut are preferably provided with left-handed screw-threads, so that when the key or button 13 is turned to The reservoir is l the right, thekpiston 11 will be moved to- Ward the closed end of the reservoir. In order that the piston may be given a longitudinal movement, within said reservoir when the screw is rotated, some means mustbe provided to prevent the piston from being rotated with the screw rod. To this end, I prefer to crimp the tube 7 longitudinally and thereby to provide a bead, as 17 extending inwardly of the tube or receptacle and substantially the full length thereof, to form a. piston guide. I cut a notch 1S 'in one edge of the piston, of such size as to permit easy free longitudinal movement of the piston wit-hin said receptacle and which will at the same time prevent the rotation of the piston. The external groove 19,v within the bead 17, from the rear end of the reservoir to a point near the center thereof, by the cooperation of the wall 20, ,forms a conduit to convey the material from the receptacle 7 through the opening 21 to the terminal opening 22, which latter is located in the midst of the tufts of bristles of the brush. 1

It is now clearly apparent that if the receptaole 7 be filled with a material, such as relatively soft soap or the-like, and the button 13 be turned to the right, that the piston will be, thereby, moved'toward the closed end of the receptacle and a corresponding quantity of such material will be thus eX- pressed from said reservoir and will be delivered through the conduit 20 to the bristles to be by them distributed, as in common use of brushes.

It is desirable to detachably secure the brush and reservoir so that new parts may be supplied without the necessity of renewing the entire structure.

To the lower portion of the tube 7 I se cure a sheet metal base structure 24 having a flat base part 25, perforated at intervals to receive the coperating fastening members which are secured to the upper surface of the brush back 26. These members are in the form of spring studs 27 located on, and secured to. the brush back, so that they will register with the attaching perforations made in the flat base part 25. To apply the reservoir to the brush it is only necessary to place the parts in proper position and press them together until` the resilient head ed studs 217 pass through the respective perforations. To separate the parts it is only necessary to pull them apart.

The brush 5 is composed of a fiat back 26, provided With the usual assemblage of tufts of bristles 28, secured in the usual manner to provide a flat bristle surface.

There are conditions when a brush, having a circular bristle surface, is desirable, in Which case a curved part 26 having bristles 28 secured thereto, and having correspondingly curved surfaces may be employed, instead of the Hat brush structure, in which event, longitudinal grooves 30-30 should be made in the back 26 and corresponding beads 3L-3l should be secured to the sides of the receptacle 7, so that the reservoir tube "may be slid into the curved bristle-carrying structure as a means for detachably securing the parts together.

When it is desirable to fill the receptacle, the piston and feed rod may be removed therefrom by detaching the closure 9, which may be secured in place by a screw-thread means, bayonet-joint, or otherwise, and by replacing same after filling, the device is again ready for use.

My improved brush may be used Where soap and like material are to be applied by a brushsuch as in scrubbing floors, Washing rugs, or carpets, or for the application of other substances in massage manipulation and the like, in which latter event the form shown in Fig. 5 is preferable.

I have herein described an embodiment of my invention Without any attempt to disclose the many variations that may be made therefrom Within ordinary skill Within the scope of the claims.

lVhat I claim is:

l. In a device of the character described, a tubular reservoir and an elongated brush, eyelets and cooperative spring studs carried by the respective parts for detachably securing said parts together, and means for feeding material from said reservoir through the back of the brush into the bristles thereof.

2. In a device of the character described, a brush comprising a back and bristles secured therein, a tubular reservoir detachably secured longitudinally to said back, a conduit from said reservoir extending along the under side thereof and projecting through said back into the bristle space, said conduit located 'longitudinally between said reservoir and back, a piston Within said reservoir, and means for moving said pis- 'ton to express the contents of said reservoir into said bristle space.

3. In a device of the character described, a brush, and a cylindrical reservoir of substantially equal length, detachably attach-l able in longitudinal relation, spring studs secured to one member, the other member provided With registering perforations for coperation With said studs as means of fastening, whereby pressing the parts together secures them in substantial relation.

4t. In a device of the character described, an elongated cylindrical reservoir closed at one end and provided With a longitudinal crimp in the Walls thereof to form an internal piston-guiding bead and an exterior groove, a piston Within said cylinder provided With a notch overlying said bead, a rotary means for moving said piston longitudinally of the cylinder toward and from the closed end, and a conduit formed in part by said exterior groove communicating With the closed end of said cylinder, at one end, and provided With a right angle delivery spout extending into the midst of the bristles at the other end.

In testimony whereof I hereunto set my hand in the presence of tvvo Witnesses.
