FOUNTAIN sHAvING-BBUsH.

Specification of Letters Patent.

Application filed July 2'5, 1917. Serial No. 182,687. v

To all whom itmay concern:

Be it known that I, WILLIAM F. WREN, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented new and useful Improvements in Fountain Shav ing-Brushes, of which the following is a specificatio This invention relates to improvements in fountain brushes. and has to do more par-- ticularly with improvements ;in shaving brushes wherein the soap to form the lather is supplied to the interior of the brush.

One of the objects 'of my invention is to provide a shaving brush especially equipped to coact with an original package of manufacture, in dispensing the soap or other contents of the package into the brush. Thus the brush would be especially made for use in connection with a specific and original article of manufacture, and vice versa.

My invention includes a hollow handle adapted to receive a tube of shaving paste or soap, and the handle is equipped with a brush discharge spout which is arranged for connection with the discharge opening of the tube so that the tube will discharge directly into said spout. The original package contains a follower which is adapted to co act with manually operable means on the brush handle to advance the follower and force the contents of the tube through the spout and into the brush.

A further feature of novelty consists in providing the spout with a closure which is adapted to be opened when the contents of the tube is forced through the spout, the valve closure being arranged in a manner to cause the bristles of the brush to seat the closure when the brush is flexed by wiping engagementto the face. Thus if the contents of the tube is especially fluid, in consistency, theimproved valve will prevent waste of the soap.

My inventionincludes the novel form of brush, and the novel form of the original tion will be more fully described in connection with the accompanying drawings and" will be more particularly pointed out in and by the appended claims.

In the drawings: a

Figure 1 is a view in elevation of my proved fountain shaving brush.

Fig. 2 is a vertical longitudinal sectional view thereof.

Fig. 3 is a view partly in'elevation' and partly a section of the original package or tube detached from the brush.

Fig. 4 is a view in elevation of a portion of the follower actuating means.

Fig. 5 is an enlarged sectional view of the discharge end of the paste tube.

Like characters of reference designate similar parts throughout the different figures of the drawings.

As shown, a handle structure is provided which comprises a handle portion 1 and a brush portion 2. The brush portion'2 consists of a ferrule 3 to which the bristles or hairs of the brush 4, are secured. The ferrule 3 is exteriorly threaded at 5 andis provided with an end wall 6. A discharge tube 7 is connected at 8 to the end wall 6 and said discharge tube is shown interiorly threaded at its intake end. Slightly beyond its intake end, the discharge tube 7 is reduced at 9 and the same projects beyond the ferrule, or in other words the point of mount of the bristles, into the interior thereof. A valve closure 10 is adapted to seat against the terminal end of the tube and it will be noticed that the closure 10 projects somewhat beyond said terminal end. Therefore when the hairs of the brush are bent or flexed as a result of wiping engagement in spreading the lather over the face, the brush hairs will engage the closure and seat the same to prevent an excess or wasteful amount of soap being delivered to the brush. This is especially important where the paste becomes warm and its consistency is more fluid than would be the case in cold weather, for instance. This feature is also important when the soap or paste is initially made of r a somewhat fluid consistency.

the closure more accurate, I may provide the latter with a stem 12, having guiding pins 13 which will hold the closure to a linear path of movement thereby always insuring a tight seat of the closure against the terminal end of the discharge tube. In order to limit opening movement of the closure, 1 provide the stem 12 with a stop bar 1 1 which is adapted to engage the inner wall of the discharge tube at the point of reduction of the latter.

The handle portion 1 comprises a hollow cylindrical body 15 which is threaded at its discharge end at 16 for detachable connection with the ferrule 3. A cap 17 is pro-' vided for closing the remaining end of the handle 15. In accordance with this construction, the cap 17 is not threaded onto the handle portion 15 because the latter is usually made of very thin material and it is desirable to have the interior of the handle of uniform internal diameter for a reason which will presently appear. Therefore I have provided a bayonet joint connection consisting of a slot 18, formed in the cap, and a pin 19 mounted upon the handle 15. Thus in one direction, rotary thrust on the cap will not disengage the same from the handle.

It is one of. the features of my invention to provide a shaving brush which is especially designed for coaction with an original package of manufacture, such for in stance as a tube of shaving cream. I have shown a tube in Fig. 3, as indicated at 19, the lower end being reduced at 20 to abut against a coacting reduction 21, of the bandle 15, to limit insertion of the tube therein. The tube 19 is provided with the usual externally threaded discharge end 22, which is closed by a cap 23. In the remaining end of the tube, after the contents 24 have been packed in, is a follower 25. This follower 25 is provided with an interiorly threaded and centrally disposed hub 26. I may provide the follower 25 with a facing of thin rubber or like gasket 27, the peripheral margin 28 of which extends about the periphery of the follower to make a tight fit against the inner wall of tube 19. A seal or cap 29 is placed over the end of the tube 19 when the tube is closed by the manufacturer to form the original package. Thus there will be a slight space between the follower and the sealing means, the purpose of which will presently appear.

While my improved brush is not absolutely dependent for use in connection with this special type of original package, it will now be clear that when this package is used, the tube will be inserted into the handle after the cap 23 has been removed, and when the ferrule 3 is threaded onto the handle 15 the threads of the dischar e tube 7 will turn onto the exterior threa s of the discharge end 22 in such a manner as to secure the tube of paste in the handle. Of course it will be dithcult to rotate the tube of paste in the handle to make this thread connection, although this might be possible notwithstanding the fact that the tube is intended to fit rather snugly in the handle. It will be noted that removal of the ferrule 3 from the handle will greatly facilitate the operation of removing an empty tube and therefore, in this combination, I consider it an important feature of the invention to provide a removable brush ferrule which is adapted, when applied to a handle, to make threaded connection with the handle, and with an original package inside of the handle, simultaneously.

After the paste tube has been inserted into the handle, with the seal 29 previously removed, and all the parts being connected as shown in Fig. 2, then the actuating mechanism which I am now about to describe will be applied.

This actuating mechanism comprises a threaded actuating member, preferably in the form of a rod 30, which is of a length approximately equal to the length of the paste tube. The rod 30 is reduced at 31 to provide a shoulder 32, and the shoulder 32 abuts against the cap 17 so that the latter will prevent longitudinal movement of the rod or spindle 30 in a direction outwardly from the handle. The rod 30 is rotatively mounted in the cap 17. An actuating member 33 shown in the form of a knurled disk seats on the exterior of the cap 17 and is securely fixed to the reduced end 31, of the rod 30. Thus when the cap 17 is removed the rod and disk 30 and 33 will also be removed, from the handle.

Assuming that the paste tube has been inserted into the handle with the cap 17 detached andthe seal 29'removed, then the rod 30 will be turned into and through the follower and downwardly in the paste tube until the cap 17 is in a position to be secured as shown in Fig. 2. The rod 30 will have a left hand thread so that by rotating the disk 33. to the right, the rod 30 will advance the follower downwardly in the paste tube from the position shown in Fig. 3 to the position shown in Fig. 2, and so on, until the contents of the paste tube are used up.

It will now be clear that it is not necessary to transfer the shavin soap or paste from the initial original pac age or tube to the handle, and this advantage not only renders the device more sanitary but it greatly facilitates the operation of using the paste. It will also be understood that a hollow brush handle might become very unsanitary by reason of repeated use, whereas with the present device, the soap or paste is only in contact with the tin or lead of the original package. As regards the removable brush portion, this can be easily cleaned at any time.

Furthermore, by placing the paste inside of the handle, it is never'necessary to carry the paste as a separate article and therefore the device of my invention is particularly convenient to travelers.

While I have herein shown and described one specific form of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.

I claim:

1. In a fountain shaving brush device, a hollow handle structure provided with a lathering brush, said structure having a. soap discharging tube delivering interiorly of said brush, and freely movable means normally unrestrained against opening or closing movement and actuated by flexure of the brlstles for closing the discharge end of said tube, substantially as described.
