Specification of Letters Patent.

Patented J une 9, 1914.

Application led September 24, 1913. Serial No. 791,535.

To all lwhom it may concern:

Be it known that we, GEORGE SrMAR'rIN and, MAX BERGER, citizens of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

The brush which is the subject matter-of the present application for patent is de- -signed more particularly to be used for cleaning the type of typewriters, letter presses, or other writing and printing machines, as well as printers forms, and its object is to provide a brush by which the cleaning of the type can be done easily and thoroughly, without loss of time and with a considerable saving of labor. This object is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which- Figure 1 is aside elevation of the brush; Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1, and Fig. 3 is a cross-section on the line 3-3 ofl Fig. l.

Referring specificall to the drawing, 5 denotes the head of a rush having bristles 6 and 7, respectively, on opposite sides, a double brush .thus being had. The head has a central longitudinal passage 8 extending thereinto from the rear end of the head and terminating short of the forward end thereof. From one side of this passage minute orifices 9 lead through the head to that side thereof carrying the bristles 6 and 4open through said side. A cleansing fluid, such as gasolene is adapted to be discharged through the orifices onto the bristles 6, this part of the brush therefore forming a fountain brush,

The device is provided with a hollow, cylindrical handle 10 carrying at its outer end a cap 11 which is screwed on and is thus readily removable from the handle. .The cap has an externally screw-threaded nipple 12 which is screwed into the outer end of the passage `8, whereby a separable connection between the cap and the brush head 5 is der 16 in the cap and across-pin 17 on the valve stem. a

The handle 10 carries a rod 18 for operatlng the valve 13. This rod extends centrally and lengthwise through the handle, from the butt end of which `it rejects and is fit ted thereat with a push utton 19. In the hollow of the handle 10 is a s ider 20 which supports the forward end o the rod, and between this spider and a cross-pin 21 on the rod, a spring 22 is coiled around the latter, which serves to normally hold the rod retracted. The rod is in line with the valve stem 14, and when pushed forward it pushes against the inner end of the valve stem and unseats the valve 13. The rod is operated, to 'open the valve, by pressing on the button 19, andy upon removing the pressure the spring 22 retracts the rod and allows the spring 15 to close the valve.

The handle 10 is hollow in order that it may serve as a container for the gasolene or other cleansin fluid, the same being discharged onto t e bristles 6 when the valve 13 is opened, the fluid thereupon discharging into the 'passage 8 and `flowing through the orifices 9 to the bristles 6.

The rear or butt end of the handle 10 is closed by a plug 23 having a central air port 2.4, through which the rod 18 passes. The rod carries a valve 25 which seats over the air port when the rod is in retracted position, to prevent leakage of the cleansing fluid from the butt end of the handle. When the rod is pushed in to open the valve 13, the valve 25 is unseated and air is allowed to enter the hollow of the handle containing thesupply of cleansing fluid, and the latter is freely discharged. The cap 11 is removable from the handle 10, as hereinbefore described, in order to permit the latter to be filled with the cleansing fluid.

In use, the fountain brush formed by the bristles 6 is first employed to remove all accumulations on the type, after which the type is brushed with the bristles 7, which latter remain dry. By this operation, the type can be quickly and thoroughly cleaned. The removal of the cap 11 does not disturb the valve 13 as the valve stem 14 and the rod 18 are separate.

We claim:

A brush comprising a head carrying bristles and having a passage leading from one end of the head, with orifices leading from the passage to the bristles, a hollow end of the handle, and to the aforesaid pas'- the air port When the rod is advanced to sage, a Valve carried by the cap and having open the first-mentioned valve.
