Where liquid is run through a funnel into an opaque bottle or earthen jug, the filling cannot be watched, and if not watched constantly, the vessel will overflow. This can be obviated by applying the automatic valve to the funnel stem, as shown. A washer support is soldered or otherwise fastened in the upper end of the stem, or at the base of the sloping part, and a crossbar is fastened to its upper surface across the hole. The crossbar is centrally drilled to receive a small rod or wire, to which is attached a valve that will cover the hole in the washer. A cork is stuck on the lower end of the rod. The location of the cork on the rod should be at a point a little below the level to which the bottle or vessel is to be filled.—Contributed by H. W. Hilton, Hopington, B. C.
Chisel Holder for Whetting
To obtain the proper slope and apply a fine cutting edge, the plane iron or chisel must be held at the proper slope while grinding, and especially so when whetting. The illustration shows a holder to keep the iron or chisel at the proper slope. It consists of a block of wood with a sloping cut at the right angle to make two pieces. One of these pieces is permanently fastened to the strip at the back, while the other is held with a bolt passing through a notch in the strip for adjusting or clamping. The rear end of the back piece is fitted with a large screw hook or L-hook to provide a slide to keep the rear end of the holder at the right height. The iron or chisel is inserted between the sloping edges of the blocks and clamped in place, then the L-screw is adjusted for height to secure the proper angle on the stone. It is then only necessary to move the block and tool back and forth over the stone.
The Tool Edge is Kept at the Proper Angle While It is Run over the Stone
A Large Hole in a Small Piece of Paper
It would seem impossible to cut a hole in a piece of paper, 2 in. wide and 3 in. long, large enough to allow a person's body to pass through it, but if carefully cut as shown by the lines in the sketch, one will find with surprise that the paper can be extended so that the feat is easily accomplished. Make the cuts about 1/8 in. apart and these will allow the paper to expand several times its size.—Contributed by H. Martine Warner, E. Orange, N. J.
