The Long-Handled Fountain Brush: A Ring of Holes Wets the Bristles From the Ground
Washing an upper window or a railway car means a ladder, a bucket and a brush that dries out.
George D. Membery of Hamilton, Ontario, received US 714,814, dated 2 December 1902, for a fountain brush "with handle adapted for the outside of windows, railway-cars, buggies, and the like": a circular brush fixed to a perforated circular tube, set oblique on a nozzle at the top of a hollow handle fed by a hose, with one tap for the ring and one for the nozzle's end.
This rung works out how much pressure the handle's height costs, then bends a copper ring, fixes a brush to it on a copper handle and measures the flow at the bristles.

"The brush is preferably in oblique position to the handle H in order to allow the operator to stand a desirable distance from the object being washed and sprayed. The length of the handle H may be from six to twelve feet, more or less, as desired to suit the purpose set forth."
"The water flows through the hose J, thence through the handle H and into the nozzle E, thence through the pipe connection F and into the circular tube C and out through the apertures 2 of the tube C, and thence on and between the hairs of the brush A, thus saturating the brush with water, which is regulated by means of the tap 5."

Push both ring ends into a tee from the brass fittings and tighten. Fit 60 mm of 10 mm copper tube in the tee's third port and bend it 60° so the ring sits oblique to the handle.

History and honest limits
History and honest limits
**George D. Membery** of Hamilton, Ontario, filed US 714,814 on 25 April 1902; it is dated 2 December 1902. The brush's base is held to the tube by bands screwed to its rear side. The nozzle has its own tap 4, so water may also leave the nozzle's end; either tap may be opened or closed alone.
**Honest limits.** Our build has no separate nozzle and uses a rectangular scrub brush where his is circular. The notebook ignores friction in the hose and handle. Your measured flows are the result.
