LOUIS D. CORIELL, 0F BALTIMORE, MARYLAND.
To all whom it may concern:
Be it known that I, LOUIS D. 'CORIELL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new anduseful Improve ments in Shaving-Brushes, of which-the following is a specification.
The purpose of this .invention is to provide a shaving brush head of inexpensive construction which can be applied to a collapsible tube containing semi-fluid shaving soap so that the tube forms a handle for the brush, the head being formed so that all of the material that can be forced out of the tube by collapsing it will be delivered directly at the base of the bristles, or in a cavity inclosed by the bristles of the brush. The brush head is also so formed as to cause the bristles to converge over the end of the tube and thus retain the soap ejected from the tube.
The details of my invention will be clear from the following description, taken in connection with the accompanying drawing, in which, 1
Figure 1 is a side view of the brush hea and tube attached thereto; Fig. 2 is a view showing the brush head in central section and the tube in side elevation; and, Fig. 3 is a plan view of the rear end of the brush head.
Referring to'th'e -drawing, a indicates a brush head, and 6 indicates a collapsible tube adapted to contain shaving soap in semi-fluid condition. The tube comprises a body 1 of metal foil or other compressible material and a rigid conical head 2, from which projects a threaded nipple 3, forming the outlet for the tube. The head a comprises a concavo-convex base 4, having outer and inner tubular walls 5 and 6 projecting from its convex side, said walls having their adjacent faces. 5 and 6, respectively, converging toward the outer end of the brush. The wall 6 is internally threaded, as indicated' by the reference numeral 7, and adapted to receive the threaded nipple 3, which 'is of substantially the same height as said wall. When the tube 1 is fitted to the head, as showniu Fig. 2, the convex end of the tube fits closely against the concave side of the base 4, andthe outer end of the nipple extends through the threaded opening in the inner wall to the forward end of said wall, as shown. The head a is also provided with a tlange 9 surrounding the con- Specification of Letters Patent.

cave side of the base, and projecting a short distance beyond the rigid head 2 on the tube when the tube is connected to the brush head. This flange is provided with threads 10 to receive a cap (not shown) for covering the brush head when the latter is not in use. The bristles 8 of the brush are suitably secured in the annular recess formed between the walls 5 .and 6, and, because of the convergence of the adjacent faces of said walls, the bristles converge and form a pocket 8* on the tube.
When the brush head is secured upon the tube as shown in the drawing, and the tube is compressed, the soap is ejected from the nipple into the pocket 8 directly at the base of the bristles, and cannot fall out if the brush be inverted because of the convergence of the bristles which close the outer end of the pocket. The application of water to the brush causes a sufficient amount of soap to pass through the bristles to form a lather. As the nipple extends entirely through the brush head, it will be seen that all of the soap that can be forced out of the tube by collapsing or compressing it from time to time will be delivered directly into the pocket at the base of the bristles. Hence all of the material in the tube can be used, as there is no passageway in the head extending beyond the nipple, to carry the soap to the bristles, which passageway, if present,
would retain a certain amount of soap and the base of the bristles from the nipple on.
the tube, and when an empty tube is removed and a full tube substituted, there is no waste of soap other than what is contained in the nipple itself and which it is impossible to eject.
When the tube is connected to the head, as shown in the drawing, the rigid end of the tube fits tightly against the brush head and, in using the brush, which is grasped usually by the head, the inertia of the tube is apt to cause breakage or damage to the tube along the joint-between the foil and the rigid metal end. In order to avoid breakage at this point, the flange 9is provided on the brush head, which flange extends be yond the joint to a suflicient extent to relieve the stress at the joint and thus preserve thetube.
directly in line with the nipple That I claim is:
A shavin brush head comprising a con-.
cavo-convex base having outer and inner tubular walls projecting from its convex side to form therebetween a recess for the bristles, said inner wall being internally threaded and said base having a short integral flange extending around its concave side, in combination with a'tube comprising a metal foil wall and a rigid convex end, the latter provided with a threaded nipple, the convex side of the base adapted to fit against
