Feb. 1, 1966 w. A. GAINES MAGAZINE TYPE SHAVING BRUSH Original Filed July 29, 1955 IN V EN T08 8 W M 6 h M K, M

United States Patent 2 Claims. c1. 1s ss2 It has heretofore been proposed to provide containers holding under pressure a substance adapted, when released by operation of a suitable valve, to form a lather, and lathering materials so packaged have gained widespread commercial favor in recent years. The practice is, however, to apply thelather to the face with the fingers, and this, to many, is an undesirable feature of a shaving material of this type. Hence, those men who prefer to apply a shaving lather by means of a brush have, in general, refrained from use of a lathering sub stance confined under pressure. Further, the use of a shaving brush has the advantage that it warms the lather when the same is being applied, in view of the practice of first immersing the bristles of the brush in warm water.

The main object of the present invention, in view of the above, is to provide a combination dispenser for lather with said dispenser being of the type that maintains the lathering substances under substantial pressure. It is proposed, in carrying out this main object of the invenion, to provide a device of the nature referred to which will save time, by directing into the brush a quantity of lather responsive merely to depression of a conveniently located button provided on the brush handle. It is further proposed to provide a device as stated wherein the lather will be automatically warmed for use as it enters the bristles, assuming that the bristles of the brush have previously been immersed in hot water.

Still further, it is an object of the invention to provide a combination device as stated which will save space when not in use, due to the assembly of a shaving brush with a lathering dispenser where heretofore these have been separated articles.

Other objects will appear from the following description, the claims appended thereto, and from the annexed drawings, in which like reference characters designate like parts throughout the several views, and wherein:

FIGURE 1 is a view partly in side elevation and partly in longitudinal section of a combination device formed according to the present invention;

FIGURE 2 is a transverse sectional view on 22 of FIGURE 1; and

FIGURE 3 is a transverse sectional view on line 33 of FIGURE 1. l The reference numeral designates a housing of cylindrical formation formed open at its outer end. A closure cap 12, having a peripheral, internally threaded flange, is engaged with a reduced, threaded extension 14 formed upon the outer end of the housing.

As its inner end, the housing 10 is integral with a bulbous body portion 15 of the handle, and said body portion, at the end thereof remote from its integral connection to the housing 10, is formed with an out wardly flaring opening 16 in which is engaged fixedly a 'complementarily flared, funnel-like liner, defining within the body portion a chamber into which the lather is forced when released from the cartridge or container in which said lathering substance is maintained normally under pressure, awaiting use.

At its end, the liner 18 is formed with internal threads 20, and the threaded inner end portion of the liner is in communication with a counterbore 22 of the body portion 15, communicating in turn with the interior of the housing 10.

3,231,923 Patented Feb. 1, 1966 The counterbored portion 22 of the body portion 15 is adapted to receive a neck portion 24 provided upon a cartridge or container 26, which completely fills the housing and bears against abutment 27, and is adapted to hold a quantity of a lathering substance under pressure. Said cartridge is formed with a threaded, reduced extension provided upon the neck 22, threadedly engageable with the threads 20, and said extension in turn merges into a tapering, elongated nozzle 28 extending axially within the liner 18, so as to discharge the lathering substance within the chamber of the body portion. The nozzle is of the type which is adapted to be normally maintained in the position thereof shown in FIGURE 1, but which is nevertheless capable of being laterally tilted, for the purpose of opening a valve, not shown, provided within the cartridge, thus to release the lathering substance. The manner in which the nozzle is tiltably mounted, and the valve construction that results in discharge of the contents of the cartridge when said nozzle is so tilted, are known per se in the art of dispensing substances under gaseous pressure, nozzles and valves of this type being already in use on containers used for the purpose of dispensing whipped cream or equivalent foods, and being also in use on containers in which shaving cream is dispensed.

At its larger end, the liner 18 is integral with a circumferential, depending, internally threaded flange 30, and said larger end of the liner is formed with an end wall 32 having a plurality of openings 34 (see FIGURE 2). Threadedly engaged Within the flange, and bearing tightly against the end wall, is the fiat, circular head 36 of a brush element provided with bristles 38. Formed in the head 36 are openings 40' registering with the openings 34 of end wall 32.

In the side of the body portion 15 there is formed a radially extending recess 42, said recess terminating, at its inner end, adjacent the shaving-cream-receiving cavity. At its inner end, the recess is in communication with a relatively small passage 44 of non-circular cross section, within which is slidably engaged a plunger 46 of complementary cross section. Plunger 46 projects into the shaving-cream-receiving cavity or chamber of the body portion 15, and is formed at its inner end with an eye 48 receiving the tapered nozzle 28.

ClICUIILPOSfid about the plunger 46 within the recess 42 is a compression, coil spring 50 abutting at one end against the inner wall of the cavity 42, and at its opposite end against a collar 52. Collar 52 is fixedly secured to the plunger intermediate opposite ends thereof, and the outer end portion of the plunger is threaded and terminates at its outer extremity in a circumferential flange 54. Flange 54, in the expanded condition of the spring 50 shown in FIGURE 1, is disposed approximately flush with the curved surface of the body portion 15.

Threadedly engaged with the outer end portion of the plunger is a knob 56, the outer end portion of which is enlarged in diameter and recessed to receive the flanged extremity 54 of the plunger. The axial recess in which said extremity of the plunger is disposed in the knob merges into a threaded, reduced axial bore of the knob in which the outer end portion of the plunger is engaged.

By reason of this construction, the knob is adapted to be threaded in an axial direction upon the plunger, inwardly from the use position shown in FIGURE 1. When the device is not in use, it is desirable to prevent accidental depression of the plunger, since this will cause a dispensing of the lather. Therefore, under these conditions, the knob is threaded inwardly within the recess 42, until its outer end is substantially flush with the curved outer surface of the body portion. With the knob threaded inwardy in this manner, there is a minimum amount of projection of the plunger from the body portion 15, and hence, accidental depression of the plunger, if not completely eliminated, is at least rendered difficult.

Subsequently, when the device is again to be used, the knob is threaded outwardly to its FIGURE 1 position, and is now disposed where it will be capable of being depressed conveniently by a user whose hand is grapsing the handle constituted by the housing 10, with the thumb free to depress the knob.

By reason of the construction illustrated and described, it will be seen that the following initial purchase of the combination lather dispenser and brush, one may, on exhaustion of each cartridge 26, purchase a new cartridge, which is readily insertable within the housing, in substitution for the old cartridge. The closure cap is then threaded onto the housing 10, and the device is again ready for use.

In use of the device, the bristles 38 will be first immersed in hot water, and then, the knob 56 is pressed to shift the plunger 46 to the left in FIGURE 1. This in turn exerts a lateral pressure on the nozzle 28, causing the valve of the cartridge to be opened. A valve of a cartridge of this type is conventionally provided with spring means or its equivalent, stressed to return the nozzle to the axial position thereof, to close the valve, and the spring 50 is further adapted, each time the valve is opened, to return the nozzle to its closed position. Thus, the opening and closing of the valve is assured, and with the construction illustrated, in fact, a cartridge designed especially for use in the device may be equipped with a valve that is not inherently adapted to return to closed position, since each time the knob 56 is released, the spring 50 discharges the function of returning the nozzle to its FIGURE 1, valveclosing position.

In any event, when the knob 56 is depressed, the substance held under pressure within the cartridge is dispensed, in an amount determined by the length of time the knob is held depressed, into the chamber defined by the funnel-like liner 18, and passed through said chamber and into the bristles, through the registering openings 34, 40.

In this'way, as the brush is manipulated to apply the latter to the face, one can periodically force a foamy lather under pressure into the bristles, so that on the continued movement of the bristles over the face, the lather will be uniformly spread and worked into the heard.

The construction, as will be appreciated, provides a combination of a shaving brush of substantially conventional size, with an insert or cartridge to which a lathering substance is maintained under pressure, the arrangement being one which permits a substantial saving of time in the operation of appying the lather to the face, and further warms the lather for use. Still further, application of the lather by hand or the making of the lather by hand is eliminated, and substantial space is saved by reason of the combination of both of these normally separated articles in a unitary device.

If desired, a cover may be provided, to enclose the bristles when the shaving brush is not in use, or when the brush is being packed in a traveling bag. Such a cover would be so designed as to be readily fitted over the head 36 of the brush and the flange 39, and may be equipped with means interengaging with complementary means on said head and/or flange for securing the cover against accidental removal.

It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claims.
