The Finger-Valve Fountain Bath Brush: Press to Run, Let Go to Stop

A bath brush fed from a hose runs all the time, or needs a tap out of reach. Daniel S. Koons and William F. Moughler of Chicago received US 634,527, dated 10 October 1899, for "a fountain bath-brush": a false back with a water passage, joined to the brush by a hollow screw whose perforated head lets the water out among the bristles, with a valve that a spring and the water pressure hold shut until a finger presses its stem, and a strap that holds the hand to the brush. This rung works out the finger force, then builds the false back on a scrub brush with a tyre valve as the finger valve, and measures the force and the flow.

A brush that feeds itself before it

The embedded blueprint feeds soap from inside a shaving brush. Koons and Moughler feed water, and give the finger a valve to start and stop it.

Read US 634,527

"Said valve is held normally closed by means of a spring 9 and also by the water-pressure, as will be obvious." "A strap k is secured at the sides of said back B' and passes over the latter, so that by inserting the hand between said back B' and said strap k the brush can be firmly held and the fingers at the same time kept in position to operate the valve."

Bore the false back

Cut a hardwood block 120 × 50 × 22 mm. Drill a 6 mm passage 90 mm along its centre from one end, and a 6 mm hole down from the top to meet it 30 mm from the far end.

Fit the finger valve

Drill a hole across the passage 20 mm from the inlet to take a tyre valve, pin upward. Epoxy it in so the water must pass through it.

History and honest limits

**Daniel S. Koons** and **William F. Moughler** of Chicago filed US 634,527 on 21 September 1898; it is dated 10 October 1899. They called it a self-cleansing brush. Its handle is telescopic, with a stuffing-box between the two members, and the hose can be led through it to the brush; a second form uses a nozzle as the screw joining the backs. They did not limit it to the bath. **Honest limits.** A tyre valve stands in for their seated valve and stem, and wood screws for their hollow screw. Your forces and flows are the result.
