My invention relates to a new and improved bromoil brush, that is, a brush to be utilized in the bromoil process.
One of the objects of my invention is to provide a brush which will facilitate the application of the oily pigment utilized in the bromoil process. I
Another object of my invention is to com-- bine a brush with a: spring device so that the action of the spring neutralizes the effect of the weight of thebrush.
Other objects of my invention will be set forth in the following description and drawings'which illustrate preferred embodiments thereof, it being understood that the above general statement of the objects of my invention is intended merely to generally explain the same and not to limit it in any manner. I n
Fig. l is a perspective view showing one embodiment of my invention.
Fig. 2 is a sectional'view'on the line 2'2 of Fig. 1.
Fig. 3 is a perspective view showing a second embodiment of my invention.
Fig. 4. is a section on the line 4& of Fig. 3.
Fig. 5 is a perspective view showing a third embodiment of my invention.
Fig. 6 is a section on the line 66 of Fig. 5.
The bromoil process depends upon the application of oily pigment upon a swelled gelatin relief prepared from a positive by means of a suitably shaped brush. The pigment is first applied in a somewhat thick layer and it is then distributed by dextrous manipulation of a brwh. The beautiful effect secured by the bromoil process is increased if the distribution of the pigment I can be easily and quickly eflected. This distribution is efi'ected by means of quick, light strokes and it is ordinarily rather difficult to manipulate the large brushes utilized for this purpose because the weight of such a brush produces a heavy pounding action and it is rather difficult to produce a slight falling motion when the brush is operated by hand.
It has been previously attempted to combine the brush with various devices for imparting a springy movement to the brush. For example, it has been proposed to attach a springy wire to such a brush, the said wire being perpendicular to the axis of the brush,

and to provide the free end of such a wire with a hand-hold, so that the said brush and the brush has an even stronger effect because the brush in effect is located at the end of a lever, which is a serious disadvantage. In addition, th s construction makes it even more difficult for the operator to cause the brush to contact with the desired support in order to deposit pi ment thereon. Finally, and in a device of this'kind, the brush oscillatesin' a pendulum-like manner, which is an additional disadvantage.
According to the present invention, the
' brush is combined witha spring which only permits a relative movement of the brush in a direction parallel to the axis thereof. This device largely reduces the effect of the weight of the'brushin applying the pigment.
As shown in Fig.1, the handle a of the brush is preferably cylindrical and it is connected by solder or the like to a ring?) which is located immediately above the binding of the bristles of the head of theb'rush. A
spiral spring 7 has the bottom thereof connected to the ring 6 and the spring f is coiled around the handle a of the brush so that the said handle a can move freely with respect to the spring. Hence, the handle 0; forms a relatively movable core member 10-, cated within the windings of the spiral spring f. The spring terminates at and is connected to a tubular hand-hold c which loosely surrounds the brush handle. If the brush is held by means of the hand-hold 0 and is thrust lightly against the bromoil print surface, then the spiral spring f will cause an oscillating or vibrating motion of the brush in a direction parallel to the axis of its handle. This will cause an easy and extremely delicate distribution of the pigment in a manner which cannot ordinarily be equaled by ordinary manual operation. In addition, the spring substantially neutralizes the effect of the weight of the brush so that the brush head can vibrate freely, thus accelerating and facilitating the operation to a very large extent.
The handle a is provided with a series of vertically arranged perforations d and the sleeve and the head of the handle a.
In the embodiment shown in Figs. 14, the spring or springs are external to the handle a.
In the embodiment shown in Figs. 5 and 6, the handle a is hollow and it is provided with an internal spring f the bottom of which abuts solid portion of the brush handle, so that the action of the spring f is the same as that of the spring f.-
The hollow top of the brush is provided with a vertical slot 9 and a sleeve 0 is provided with a transverse member is which fits within the slot 9 so as to suitably guide the movement of the sleeve 0 upon the handle a, and to prevent the sleeve 0 from turning on't-he handle a. A screw d may be pro vided to enable the sleeve 10 to; be adjusted upon the handle a.
I have shown a preferred embodiment of my invention, but it is clear that'numerous changes and omissions could be made With- ,out departing from its spirit.
I claim 1. A bromoil brush comprising a hand- 'movable thereto, and spring means connectingsaid handle and said sleeve said spring means being sufficiently soft to permit said brush to freely vibrate When the head thereof is pushed against the print to be covered with pigment.
3. A bromoil brush having a handle, a
sleeve adjustably located on said handle and relatively movable thereto in the adjusted position, and spring means connecting said handle and said sleeve said spring means being sufficiently soft to permit said brush to freely vibrate when the head thereof is pushed against the print to be covered with pigment.
4. A. bromoil brush having a handle, a
sleeve located on said handleand relatively movable thereto, spring means connecting said handle and said sleeve and means adapted to adjust the force of the spring means said spring means being sufficiently soft to permit said brush to freely vibrate when the head thereof is pushed against the print to be covered with pigment.
In testimony whereofI affix my signature.
DR. EMIL MAYER.
