BRUSH Filed April 1, 1929 504} W/lace Patented July 1, I930 UNlTE SADYE E. WALLACE, or SEATTLE," WASHINGTON nnusrr Application filed April 1, 1929. Serial No. 3511,5983

The invention is a brush having bristles having a hollow handle with means therein for feeding a substance that may be placed in the handle to the bristles. Y

' The object of the invention is to provide positive means for feeding a. substance placed in the handle of a brush to the bristles of the brush.

Another object of the invention is to provide means for feeding a substance from the opening in the handle of a brush to the brush which is positively operated by a rod from the bristle end of the brush;

Another object of the invention is to provide means at the bristle end of a brush for feeding a substance from an opening in the handle to the brush which will not protrude beyond the end of being used. i I

A further object ofthe invention is to provide means at the end of a brush handle which is connected to a latch at the opposite end of the brush so that it may movethe latch outward and which is so constructed that it may be turnedoto prevent the latch being moved outward should the brush drop the brush except when and strike the means at the end "of the han-v dle.

And a still further object of the invention is to provide a brush having positive means,

for feeding a substance in the handle to the bristles of the brush'which'is of a simple and economical construction.

With these ends in viewfthe invention em bodies a brush having a hollow handle with an opening extending over the bristles and apertures throughthe portion ofthehandle at the base of the bristles, plunger in the handle, and a rod extending from the plunger to both ends with one end extending beyond the end of the handle and also with cover plates-forthe said-apertures .at the,

base of the bristles.

Other features and advantagesof the invention will appear from the following description taken in connection with the draw- 1ngs,where1n: V Figure 1 is a side elevation of a.

brush with the cap shown in section.

Figure 2 is a longitudinal section through the brush on an enlarged scale.

Figure 3 is a sectional plan showing the recesses for the gripping latch at the brush end.

Figure 4 is a cross section through the handle on line 4L of Figure 2.

Figure 5 is a longitudinal section through the gripping end showing an alternate. arrangement in which a plurality of openings are provided instead of thesingle opening as shown in Figure 2. I

In the drawings the device is shown as it would be made wherein numeral 1 indicates the'handle, numeral 2 the bristles, and numeral 3 the rod extending through the han dle. Thehandlel may be made of any suitable design and of any suitable material. In the design shown it is provided with a comparativelyflat portion, as indicated by the numeral 4, in one side of which the bristles 2 are placed and this is connected to a somewhat larger cylindrical portion, as indicated by the numeral 5, forming the handlethat is gripped by hand. The'underside of the handle is provided with an opening 6 having grooves 7 at the edges thereof and a cover 10 and is provided with a notch 11 so that itmay readily be withdrawn from the end of the handle to refill the opening in the handle or to clean the same. It will be observed that this cover plate may be attached to the handle by any other suitable means and may be of any suitable size or design. A piston 12 is mounted in the handle upon the rod 3 with one end of the rod-extending beyond the end of, the handle and this end of the rod is provided with a knob 13' having a projection 14 on one side of the knob 13. It will be observed that the knob 13v 'may pass through an opening 15 intheend of the handle. The opening 15 is provided with a notch 16 in one side through which the projection 14 may pass when the knob 13 is in such a position that the projection will register with the notch.

At the opposite end of the rod 3, which extends through the handle, is a latch 17 and the end of the handle is provided with a recess 18 to accommodate the latch so that the latch will not extend beyond the limits of the handle. It will be observed, however, that when the. knob 13 is pressed inward it will force the latch 17 out beyond the end of the handle so that it may readily be gripped bv hand. This end of the handle may beprovided with a bearing 19 having a packing gland 20 therein to prevent a substance in the handle passing out at the end I of the rod. In one side of the portion t are the bristles 2 and this surface may be provided with an aperture, as indicated by the numeral 21 and shown in Figure 2, or

a plurality of apertures, as shown in Figure '5. The rod '3 may also be provided with cover plates 22 which will form closures for the inner end of the apertures when the device is not in use and when the rod 3 is moved outward these cover plates will pass away from the apertures and permit a substance in the handle to pass to the bristles. It will be observed that as many apertures as may be desired may be used.

The brush may be provided with a'cap 23 which may be frictionally held over the end in which the bristles are located, as shown in Figure 1, and the end of the cap may be provided with slits 24: to provide ventilation for the bristles. It will be observed that the cap may be of any suitable design and may be held to the handle of the brush by any suitable means.

It will be understood that other changes may be made in the construction without de parting from the spirit of the invention. One of which changes may be in the use of the device with a brush of any other type or design, another may be in the use of a filler openingof any other type or design or in the location thereof, and still another may be in the use of othermeans for operating the piston or for preventing its operation except when desired.

The construction will be readily under stood from the foregoing description. In use the brush may be provided as shown and it'will be observed that with the apparatus in the'normal position, as shown in Figure 1, the apertures will be closed and the device maybe used normally. When it is desired to feed a fresh supply of a substance that maybe contained in the handle to the bristles ofthe brush the knob 13 is pushed inward and the latch 17 gripped and drawn outward until a sufiicient supply of the substance is forced through the apertures to the bristles. The latch 17 may then bepressed inward so that it will rest in the recess 18 and not protrude beyond the end of the brush and thebrush is ready to be used. To refill the space in the handle the cover plate 8 may be withdrawn and when the handle is filled it may readily be replaced.

Having thus fully described the inven tion what I claim as new and desire to secure by Letters Patent, is:
