1 Claim.

This invention relates to new and useful improvements and structural refinements in brushes, more specifically, s e-called fountain brushes intended for use by persons while having a bath, and the principal object of the invention is to facilitate convenient manipulation of the brush over the back of the user.

This object is achieved by providing the brush with an extensible handle which may be projected or retracted, so to speak, to the desired length, whereby the brush may be manipulated with convenience to reach all portions of the users back.

An important feature of the invention resides in providing the brush with an extensible handle which, when desired, may be retracted into the brush body, so that the latter may be employed in the conventional, well-known manner.

Another feature of the invention resides in the provision of a fountain brush including reservoirs for liquid soap from which the soap is automatically dispensed directly to the tufts of bristles.

An additional feature of the invention resides in the provision of a fountain brush which is simple in construction, which, as aforesaid, may be easily and conveniently manipulated, which will readily lend itself to economical manufacture and which is otherwise well adapted for the purpose for which it is intended.

With the above more important objects and features in view, and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and contruction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the invention.

Figure 2 is a longitudinal cross-sectional view thereof, and

Figure 3 is a cross-sectional view, taken substantially in the plane of the line 3-3 in Figure 2.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a fountain brush designated generally by the reference character [0, the same embodying in its construction, an elongated, block-shaped body l2 formed with a centrally disposed, cylindrical bore I4.

It is to be noted that one end of the bore I4 is closed as at l6, while the body I2 is provided at the remaining end of the bor (M) with a screw-threaded adapter fully described.

Tufts of bristles 20 are imbedded and secured in suitable apertures 22 formed in the lower surface 24 of the brush body l2, the latter also being formed with a pair of longitudinally extending reservoirs 26 for liquid soap, preferably disposed at the sides of the aforementioned bore M.

The body I2 is also provided with sets of passages 28 which extend between the reservoirs 26 and the tufts of bristles 20, matters being so arranged that at least one of these passages communicates with tufts of bristles, as is best shown in Figure 3.

It will be apparent from the foregoing that when the reservoirs 26 are filled with liquid soap, the soap will be automatically delivered through the passages 28 to the bristles, while the brush is being moved over the body of the user, so that the conventional necessity of applying a cake of soap to the bristles of the brush will be eliminated.

A top plate 30 is suitably fastened to the upper surface of the brush body l2 and is provided with an elongated protuberance 32 formed in the opposite longitudinal edges thereof with series of undulations 34 constituting finger-grips. The protuberance 32, together with the undulations 34, constitutes what may be referred to as a handle, whereby the entire brrush may be easily and conveniently manipulated in the conven- 'tional, well-known manner.

However, when it is desired to use the brush on the back of the bather, more specifically, when the user wishes to apply the brush to poorly accessible portions of his back, an extensible handle assembly 36 should be employed, this simply assuming the form of a plurality of tubular sections 38, 40, 42, etc., which are slidably telescoped together. It is to be noted that the handle section 38 is greatest in diameter, while the sections 40, 42 are progressively smaller, the section 38 being slidable in the bore 14 of the brush body l2. In order to guide the sliding movement of the various sections and to assure that the sections will remain extended or retracted in a predetermined relative position, friction increasing means are provided, these preferably assuming the form of resilient washers or restraining rings 44 mounted on the inner, externally screw-threaded portions 46 of the various sections. Pairs of suitable nuts 48 may be provided on the screw-threaded portions (46) for the purpose of retaining the washers 44 in position, as will be clearly apparent.

l8, hereinafter more The washer on the inner end of the handle section 42 frictionally engages the inner surface of the handle section 40, while the washer on the latter frictionally engages the inner surface of the handle section 38, etc., and the washer on the section 38 frictionally engages the bore I4, whereby undue sliding movement of the various sections is prevented. However, it should be understood that the frictional engagement of the various washers with the various sections and with the bore I4 "is such that the sections of the handle may be extended or retracted with convenience, when so desired.

The outer ends of the various sections .are guided by annular inserts or guiding rings 50 which are screw-threaded into one section and slidably engage the next section telescoped thereinto, a suitable hand-grip 52 being provided at the outer extremity of the innermost section 42, substantially as shown.

An annular retainer cap 54 is screw-threaded and positioned on the aforementioned adapter 18 of the :brush body 42, a suitable gasket 56 being interposed between the adapter and the cap. This gasket, of course, provides the necessary guide for the handle section 38 and also prevents the entire handle from becoming detached from the brush body, inasmuch as it is engageable with the nuts ('48) and washer (44) on the inner end of the section 38.

In this connection, it is also to be pointed out that the inserts 50, being engagea-ble with the nuts and washers on the inner ends of the sections 40, 42, will prevent these sections from becoming detached from the section 38, whereby the decomposition of the handle is effectively prevented.

Finally, it should be explained that the reservoirs 26 are equipped with suitable .filler plugs 58, whereby the supply of liquid soap in the reservoirs may be replenished, the plugs 58 extending through the top plate 30, substantially as shown.

Moreover, suitable control means may, of course, be employed for regulating the flow of soap through the passages 28 to the brush bristles.

It is believed that the advantages and use :of the invention will :be clearly understood from the foregoing disclosure and accordingly, further deecription thereof at this point is deemedunnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention what is claimed as new is: 1

The combination of an elongated brush body provided with a longitudinal bore and with an externally screw-threaded adapter at one end of said bore, a screw-threaded annular cap on said adapter, an annular gasket of resilient material in said cap and in engagement with the end of said adapter, and a telescopic handle comprising a set of tubular sections disposed in coaxial 'telescoped relation and each spaced from the adjacent section to provide an annular chamber therebetween, internal and external screwthreads provided at the respective outer and inner ends of said sections, an externally screwthreaded guiding ring positioned in the internally threaded outer end of each section and slidably engaging the outer surface of the next inner section, and a resilient restraining ring mounted on the externally threaded inner end of each section and frictionally engaging the inner surface of the next outer section, the restraining ring on the outermost section irictionally engaging the bore of said body, and said gasket frictionally engaging the outer surface of said outermost section.
