Patented June 10, 1930 UNITED STATES PATENT OFFICE WILLIAM A. DILLON AND CLAUDE O. WEINGAND, OF LOS ANGELES, CALIFORNIA SHAVING BRUSH Application filed March 1, 1929.

19 tion is to provide a shaving brush having a soap feeding passage extending through its handle or shank and which is adapted to be attached to and removed from a distinctive design of compressible receptacle I wherein is sold liquid shaving soap, the

shaving brush being so constructed that it can not be attached to other designs of liquid soap containers than those of the same company which is supplying the brush to 241 the public to be used with the distinctive soap container above mentioned.

A still further object of the invention is to provide improved valvular means for controlling the flow of liquid soap to the brush 5 from the container to which it is attached.

Other objects and advantages may hereinafter appear.

Referring to the accompanying drawings which illustrate what is at present deemed ;a preferred embodiment of the invention,

Fig. 1 is a vertical mid-section of the brush shown attached to a liquid soap container, the container being shown in elevation.

Fig. 2 is a reproduction of the central portion of Fig. 1 showing the parts in a different position, parts being broken away to contract the View.

Fig. 3 is a section on line 3-3 of Fig. 1. Fig. 4 is a detail of thelocking device. Referring in detail to the drawings, the shank or body portion 5 of the brush is desirably composed of vulcanized rubber and 5 .is molded over and upon a sleeve 6 which is internally screw-threaded for attachement to an externally-threaded neck 7 with which the compressible container 8 is provided. Said shank 5 contains a central bore 9 which extends from end to end thereof Serial No. 343,700.

and which communicates with the open inner end of the sleeve 6.

In order to control the flow of the liquid soap from the container 8 through the passage 9 a diagonal bore is provided 55 through the side of the shank 5 and made to communicate with the open end of the passage 9 as shown in Fig. l. The outer portion of said bore 15 is enlarged and has fitted thereinto a sleeve or elongated cap 16, said cap having an aperture through its outer end from which may be withdrawn a stem or rod 17, said rod 17 carrying at its inner end a plunger 18 which operates as a valve. The outer end of stem 17 is provided with finger-hold or operating head 20.

The sleeve 6 throughout about its lower one-half, is not provided with any threads, hence an annular space is provided around the reduced portion or nipple 7 of the container 8 when the parts are assembled, owing to the fact that the nipple 7 is externally screw-threaded for only about the outer half of its length. At the lower end of this space the sleeve 6 is provided with an internally projecting key 26. This key is adapted to cooperate with a key-way or slot 27 which extends from end to end of the threaded portion of the nipple 7.

The inner end of the brush shank 5 is provided with an internal bevel 31 bounded circumferentially by the annular shoulder 30. The outer end of the body portion of the container 8 is provided around its neck 7 with a bevel 32 which is less sloping than the surface 31 of the brush shank. Hence when the parts are screwed together the shoulder forms the sole line of contact between the brush shank and the container body, and this line, being spaced awa from the line of juncture between the neck and body of the container, danger of lateral strain causing breakage between the neck and body is reduced.

It willbe seen that when the receptacle 8 is screwed into place within the shank 6 the screw threads which connect these parts together are located beyond the unthreaded portions of the sleeve 6 and receptacle neck 7, thus providing a more stable union than would result if the threads were placed near the outer end of the shank 5. This arrangement of the threads cooperates with the arrangement of shoulders 30 and 32 set forth 5 in the preceding paragraph, to make the assembled device a strong, dependable article.

' Claims:

1. In a device of the class described, a brush head comprising a shank, a soap feeding passage being provided through said shank longitudinally thereof, the intake end portion of said passage being enlarged, a sleeve fixed within the enlarged portion of said passage, the inner part of said sleeve having internal threads and the outer part of said sleeve having an unthreaded interior surface the diameter of which is equal to that of the threaded part plus the depth of its threads, a container I 2Q having a neck portion projecting from one end thereof, said neck having its outer portion externally threaded to screw into the aforementioned threads and its inner portion unthreaded, there being a key-way cut through the threaded portion of said neck, and a key within the lower portion of said sleeve, said key being adapted to cooperate with said key-way.-

2. In a device of the class described, a

3Q; brush comprising a shank, a liquid feeding passage being provided through said shank longitudinally thereof, the intake end portion of said passage being enlarged, a sleeve fixed within the enlarged portion of said passage, the inner part of said sleeve having internal threads and the outer part of said sleeve having an unthreaded interior surface the diameter of which is equal to that of the threaded part plus the depth of its g; tl1reads,;a container having a neck portion projecting from one end thereof, said neck having its'outer portion externally threaded to screw into the aforementioned threads and its inner portion unthreaded, there being a key way cut through the threaded portion of said neck, and a key within the lower portion of said sleeve, said key'being adapted to cooperate with said key-way, said brush shank having a beveled recess 5 around the mouth of its intake and said receptacle having a less steeply beveled end portion around the base of its neck eonstructed and arranged to contact with the intake ofsaid shank solely along a line radially spaced away from said neck.

3. In a device of the class described, a brush comprising a shank, a liquid feeding passage being provided through said shank longitudinally thereof, the intake end por- 6Q tion of said passage being enlarged, the inner part of said enlarged portion of said passage having internal threads and the outer part thereof having an unthreaded interior surface the diameter of which is equal to that of the threaded part plus the 7 ate with said key-way, said brush shank having a beveled recess around the mouth of its intake and said receptacle having a less steeply beveled end portion around the base of its neck constructed and arranged to contact with the intake of said shank solely along a line radially spaced away from said neck.

In testimony whereof we hereunto aflix our signatures.
