W 4,011/ 65 US. Cl. 15-145 Int. Cl. A46b 5/02, 11/00 2 Claims ABSTRACT OF THE DISCLOSURE The present invention relates to an implement for transferring pigments. More specifically, the invention relates to an artists brush.

'In implements for transferring pigments, and particu larly but by no means exclusively in artists brushes, it is desirable to keep pigment on the transfer-portion of the implement, that is in brushes on the bristles, from drying out. It becomes very diflicult to remove dried-on pigment from the bristles and may even result in destruction of the bristles since, on removing the dried-on pigment, tearing-out or tearing-off of the bristles often cannot be avoided.

For this reason it is customary to place the brush, or at least the bristles, in a body of a liquid which is capable of preventing the pigment from drying. Such liquid may be either water if the pigment is water-soluble, or it may be a suitable paint thinner if the pigment is not water-soluble. Some brushes will not float on such liquid and it is then necessary to provide a device which can be hooked to the container in which the liquid is dis posed which prevents the brush from falling into the liquid and only lets a portion of the brush including the bristles dip into the body of liquid. Most brushes, however, will float on the surface of the liquid. The problem with these brushes resides in the fact that they Will float on the surface, that is horizontally, so that only a very few of the bristles are submerged in the liquid and thus guarded against drying-out of the pigment. Furthermore, and even if this disadvantage is accepted, it is necessary under these circumstances to provide a container having a cross-section which is so large that the brush can float freely on the surface of the liquid without bending of the bristles. Obviously, if the container is not at least as wide in cross-section as the brush is long seen from one end to the other and including the bristles, the latter will be bent by contact with the wall of the container and eventually such bending results in permanent deformation of the bristles. This then makes the brush unusable.

Taking all of these disadvantages of the prior art into account, it is a general object of the present invention to provide an implement for transferring pigments which is not subject to such drawbacks.

It is a more specific object of the invention to provide particularly an artists brush which is capable of floating in a body of liquid with at least its bristles submerged therein.

A further object of the invention is to provide such a brush which floats substantially vertically in a body of liquid into which it is placed.

In accordance with these objects and others which will become apparent hereafter, one feature of my invention resides in the provision of an implement for transferring pigments, particularly an artists brush, which comprises an elongated buoyant handle having an end, and pigment-transfer means extending from this end. Furthermore, the implement comprises means which define-s in the region of the end portion a center of gravity for the implement. In accordance with the invention the relationship between the buoyancy of the handle and the location of the center of gravity is so selected that, when the implement is placed into a body of liquid, the pigment-transfer means will submerge below the surface of the liquid and at least a substantial part of the handle will rise above the surface and be upwardly inclined relative to the same.

This is made possible by making the handle buoyant, as has already been indicated, either by making it hollow and entrapping air therein or by using a naturally buoyant material such as wood. By arranging the center of gravity so that it is located in the region of the end from which the pigment-transfer means, that is in the case of a brush the bristles, extends and by selecting the relationship between the buoyancy of the handle and the precise location of the center of gravity in such a manner that the center of gravity counteracts to some extent the buoyancy of the handle, the implement can be made to float vertically or substantially vertically in a body of liquid. Of course, it is necessary to select the location of the center of gravity in such a manner that only a front portion of the handle, together with the pigment-transfer means, will be submerged in the liquid since it is obviously not desirable to have the rear portion of the handle, which must later be gripped by the person using the implement, coated with the liquid.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accom panying drawings, in which:

FIG. 1 is a partially sectioned top-plan view of an implement in accordance with the present invention;

FIG. 2 is a partly sectioned fragmentary view of an implement embodying the present invention, but showing a diiferent embodiment;

FIG. 3 is similar to FIG. 2 but again shows another embodiment;

FIG. 4 is similar to FIGS. 2 and 3 and also shows a further embodiment; and

FIG. 5 is similar to FIG. 1, showing yet a further embodiment of the invention.

It is to be noted that in all of the figures the pigmenttransfer means, that is in the various illustrated embodiments the bristles, is designated with reference numeral 1, whereas the handle is always designated with reference numeral 2. Other reference numerals vary between the different embodiments.

Discussing now the drawing in detail, and firstly FIG. 1 thereof, it will be seen that the pigment-transfer means, which for the sake of convenience Will hereafter be referred to as the bristles, is designated with reference numeral 1 and is held in a metal or plastic sleeve 3 which constitutes a continuation of the hollow handle 2. In the embodiment of FIG. 1 the sleeve 3 is provided at its free end with an internal thread 4 whereas the front end portion of the hollow handle 2 is provided with an external thread 5 which meshes with the internal thread 4. The handle 2 may consist of a suitable synthetic plastic material, may for instance be constructed by blow mold- In accordance with the invention a weight 6 is provided in the sleeve 3 directly behind the bristles 1 and it is this weight 6 which determines the center of gravity of the entire brush. It will be noted that the sleeve 3 conically tapers towards its front, that is in the direction toward the bristles 1 and the Weight 6 is simply pressed from the rear into the sleeve 3 so as to be immovably seated therein. Reference numeral 7 indicates the forward end of the sleeve 3 at which the bristles are clamped in the sleeve 3.

As indicated earlier, a brush constructed in accordance with the embodiment of FIG. 1 will, when placed into a body of liquid, have a tendency to fioat because of the buoyancy of the handle. However, because of the forwardly located center of gravity of the brush, defined by the weight 6, the same will tilt in the liquid so that the bristles 1 and a forward portion of the brush, for instance the sleeve 3, will be submerged in the liquid whereas the remainder of the handle will extend upwardly above the liquid, forming therewith an angle of up to 90 degrees.

The embodiment of FIG. 2 differs from that of FIG. 1 in that the sleeve here is indicated with reference numeral 8 and is suitably secured by pressing, gluing or in another manner, in a cylindrically configurated front portion of the sleeve of the handle 2. A weight 10 is secured immediately behind the sleeve 8 but Within the front portion of the handle 2 and it will be understood that the Weight 10' can be secured to the sleeve 8 by screwing, by soldering, by adhesive means or by some other suitable expedient, this particular consideration forming no part of the invention. The result of this construction is the same as in FIG. 1 in that the center of gravity is determined by the weight 10 and the brush is again caused to float in the body of liquid with its bristles 1 submerged therein.

In the embodiment of FIG. 3 the sleeve is again identified with reference numeral 8 and conforms to that shown in FIG. 2. However, the weight is here located within the sleeve 8, rather than rearwardly thereof within the handle 2 as shown in FIG. 2. In FIG. 3 the weight is identified with reference numeral 11 and it will be seen that this may consist of two spherical members although the configuration is of course limited only by the space 7b available within the sleeve 8. In-turned flanges or suitable similar expedients 7a confine the weights 11 within the sleeve 8.

FIG. 4 shows an embodiment which differs from those illustrated herebefore. The hollow sleeve 2 is here shown to be provided with a massive front portion 12, which may consist of plastic material, and which is suitably secured to the front end of the hollow handle 2 by welding, adhesive securing, frictional securing or the like. The front end of the member 12 is provided with a recess 13, preferably of cylindrical configuration, in which the bristles 1 are secured, for instance by means of an adhesive. Obviously, the fact that member 12 is massive, rather than being hollow, whereas the handle 2 itself is hollow 'as in all the other embodiments, makes the front portion of the resulting brush heavier and thus locates the center of gravity at this one portion. Again, the brush will float upright or substantially upright in a body of liquid.

It should be pointed out, before passing on to FIG. 5, that the embodiments shown in FIGS. 1-4 can of course be combined in a suitable manner, if this is desired, and any possible combination of these embodiments is also desired to be encompassed by the protection sought.

Coming now to FIG. 5, it will be seen that the handle 2' shown therein is not hollow, but rather is solid. It is, however, buoyant and for this purpose consists of a material capable of floating on a body of liquid. For instance, such material may be wood or plastic. It is provided at its front end with a screw thread 14 which can be formed directly on the handle 2 or which can be formed in a metal or plastic sleeve which is then secured to the front end of handle 2. A solid member 15 is provided with a recess complementary to the front end of handle 2' and provided with an internal screw thread which meshes with the screw thread 14 so that the member 15 can be secured to the handle 2'. The front end of member 15 is provided with another recess in which the bristles 1 are secured, either directly or through the intermediary of a sleeve 8. The massive member 15 provides the forwardly located center of gravity necessary in accordance with the present invention.

It should be understood, of course, that the embodiments shown herein represent only a small number of the considerable variety of possible solutions.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of an implement for transferring pigments differing from the types described above.

While the invention has been illustrated and described as embodied in implements for transferring pigments, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
