To use the vulcanizer, clean the area around the hole in the tube with sandpaper, and cut a piece of rubber of the proper size to fit over it. Slip one of the prepared cardboard disks into the tin cover, and clamp the cover and tire with patch into the iron frame, as shown. Touch a lighted match to the cardboard disk, which will burn rapidly, but without flame, supplying sufficient heat to vulcanize the tube.—Thomas W. Benson, Hastings on Hudson, N. Y.
Rudder for a Toboggan
This Rudder for a Toboggan Insures Positive Control, and Prevents Wear on the Shoes and Clothes of the Rider
Learning to steer a toboggan by means of the foot dragged behind it is an interesting feature of the sport, but this method is dangerous at times and results in much wear on shoes and clothes. The device shown in the illustration makes this method of steering unnecessary and gives the rider accurate control over the sled. It consists of a strip of ¹⁄₄ by 1-in. iron curved to form a rudder at one end and twisted at the middle to provide a flat piece for pivoting it on the rear cleat of the sled, as shown in the working drawing below. A handle is fastened to the front end of the strip with bolts. The rudder should not be curved too deeply or it will cut through the snow and be damaged, or ruin the track.—H. B. Mclntyre, Waterville, Me.
A Window Refrigerator
A Box Fitted on the Outside of the Window to Slide in Grooves Provides a Convenient and Inexpensive Refrigerator for Winter Use
A simple method of constructing a window refrigerator that will not obstruct the light is shown in the illustration. A box was made the width of the window and was fitted to slides fastened outside the window on the side of the house. The exposed sides of the box were inclosed completely and the inner side was provided with two sliding doors. A handle was fitted to the side of the box so that, by reaching out of the window, the box could be drawn in front of the opening easily. Several shelves were fitted into it and the materials stored were not easily molested. Trunk casters attached to the bottom of the box improved the action on the lower rail.—Hubert Kann, Pittsburgh, Pa.
