RESERVOIR BLACKING-BRUS-H.

SPECIFICATION forming part of Letters Patent No. 576,992, dated February 9, 1897.

Application filed March 9, 1894.

T all whom, it 7720.3/ concern:

Be it known that I, WILLIAM HAYBALL, a citizen of the United States, residing at Portland, Multnomah county, and Stat-e of Oregon, have invented a new and useful Im provemen tin Reservoir Blacking-Brushes, of which the following i s a specification, reference being had to the accompanying drawings as a part hereof.

My invention. relates generally to reservoir blacking-brushes, but more particularly to such brushes as improved and perfected by me, and for which improvement I have made application for Letters Patent of the United States," dated August 2S, 1893, Serial No. 484,249. i

The object of :'ny present invention is to perfect the mechanism which is essential to the construction of reservoir blacking-brushes made in conformity to the plan of my prior invention and to make such mechanism better adapted to the purposes for which intended.

Referring to the drawings accompanying this specification and above referred to, Fig- 'ure l shows a longitudinal vertical section of abrush provided with a reservoir-can and operating-lever, the swab and valve mechanism being removed. Fig. 2 shows a similar section of the swab and valve mechanism. Fig. 3 is a partial plan view of the valve mechanism from the under side thereof. Fig. 4 is a detail of the valve mechanism of different construction from that seen in Fig. 2 and which may be substituted therefor. Figs. 5 and 6 are respectively top plan view and vertical section of my invention applied to a stencil-brush.

The letters and figures designate the parts of the mechanism referred to in the description of my present invention. v

The general plan of construction of my blacking-brush I have already disclosed in my said prior application for Letters Patent. Instead of using the valve mechanism for- Vinerly employed by me I substitute therefor upper end adapted to receive the threaded Serial No. 503,021. (No model.)

end of the valve-rod 2, of which valve-rod such plunger is in fact a continuation and constitutes vpart of the means provided for steadying the valve and making the'same adjustable on its seat, as will be explained later. The remaining parts of the valve mechanism area collar 4 on said plunger, a guiding device for the plunger, and a coil-spring h6. The plunger 3 is guided in a device in the form of an inverted tripod rigidly suspended from the threaded collar b2 below the fiange b', as seen in Figs. 2 and 3. The plate 6 has asquare perforation in which the square plunger 3 is guided and operates. The coilspring h6 is placed von such plunger, the head thereof bearing against vthe plate 6 of the 4guiding device and the foot thereof against the collar et at the base of the plunger. Thel valve mechanism being iixed in place in the swab and these parts then secured on the can, the valve will operate in substantially the same manner as the valve heretofore used by me, the base of the plunger 3 resting on the spring-bottom of the can and being held upon the same by the action of the coil-spring d6. Upon the brush being inverted to use the swab the liquid flows into the neck of the valve through the open sides of the guiding device for the plunger, and by pressing on the lever D the spring-bottom ofthe can, and

with it the plunger 3, resting thereon, will be raised and the valve 1 lifted off its seat, allowing the liquid blacking to escape. In the drawings said valve is represented as seated on a beveled boss or collar 7 on the interior of the neck of the valve, but there are divers other ways for seating the valve, and I do not limit myself to the particular construction shown.

To keep the blacking from spreading among the base of the bristles on the swab and to conduct the same to the surface thereof, I use a short rubber tube 8, inserted on the discharge end of the neck of the valve, such neck being provided with rim 9 to hold the Ytube, although I believe such tube would remain in place without anything to hold it.

Should the liquid iiow too freely or too scantily, the valve l could be lowered or raised ,so as to adjust the opening between the base thereof and its seat when lifted to discharge a sufficient quantity of liquid, and this adjustment of the valve is easily accomplished by means of a screw-driver inserted in anick 5 in the head of the valve. I have also modified the construction of my operating-lever somewhat to simlify the same, as illustrated in Fig. 1. The operating-lever there shown, it will be observed, is slightly curved and is pivoted between two pins 10 and 11, and such lever is slightly notched on its under side at the place Where it rests on the pin 11 to prevent such lever from moving endwise out of pla-ce. The lifting end of the lever should be provided with some bushing of soft material to prevent wear of the bottom of the can.

s is a set-screw for adjusting the lift of the lever D.

To facilitate packing my brush, the handle thereof should be constructed divided, as shown, the grip end 12 being fastened to the remaining iixed portion on the brush by means of a threaded stud and socket.

Fig. 4 represents a valve mechanism of modified construction from that seen in Fig. 2 in this, that it dispenses with a spring-bottom and uses instead thereof a cylinder 13 and piston 141, provided on the bottom ofthe reservoir-can, which bottom is rigid. In this case the base of the plunger 3 rests onihe head of the piston, and t-hc piston-rod 15 eX- tends through an opening in the bottom of the can and has a little knob at its base for the lifting end of the lever D to bear against.

My invention may also be applied to advantage to a stencil-brush, as shown in Fig. 6, the valve mechanism being substantially of the same constructionA as that seen in Fig. 2 and being operated by a rod 16, attached to the usual plunger 3 and extending vertically in the handle, which is hollow and takes the lplace of the usual reservoir-can. The top of said handle hasa circular opening` covered by a disk 18, of flexible material. The knob of the rod 1G, by the action of the coil-spring la, is caused to bear against such disk of iiexiblc material, and the valve may thus be operated by pressure of the thumb while holding the brush and working with the same. A bar 17, with an eye or collars at its center or some equivalent means, must also be provided to steady the rod 1G. From experiments made by me I believe the valve mechanism illustrated in Fig. 2 to be the most In a reservoir blacking-brush, the combination of a reservoir-chamber for containing the liquid blacking, said' reservoir having a depressible portion in its casing, a swab mounted on said reservoir and having its disk apertured to communicate with the reservoir, a valve mechanism in said opening consisting of a tube or neck, a valve adaptedy to close the discharge end of said tube, which is itself adapted to provide a seat for saidvalve, a rod depending from the base of the valve, a plunger to which said rod is secured, a guide-plate in which said plunger slides, extending from said tube or neck, and a spring for holding the valve on its seat, said plunger being arranged to be actuated by the depression of the depressible portion of the reservoir-casing when ejecting the liquid blacking, substantially as described.

In testimony whereof I have hereunto set my signaturein the presence of two witnesses.

VILLIAM HAYBALL.
