Another style of windmill can be made in this way: Place on the floor in the middle of the window a box 24 in. square, 4 ft. high. On top of this box fasten a wheel 5 ft. in diameter. On top of this wheel fasten an octagonal box 3½ ft. across at the bottom and 2 ft. at the top, 3 ft. high. On the top of this box fasten bearings for a shaft 3 ft. long. On the end of this shaft fasten four arms to measure 24 in. from shaft; also fasten a large pulley to this shaft in the center of the box. Over this pulley the belt is run to the motor below. Over the top of the box construct a roof; then at the back of the box that rests on the floor build a frame as wide as the box and 3 ft. high, this to extend to back of the window. Over this make a roof so that the apex is just a little above the large wheel. Cover all the wood with cloth, then with any kind of goods you may desire. Start your motor and you will have an old-fashioned windmill in operation.
MECHANICAL SKIRT WINDOW.
I show herewith drawings for the construction of a wheel upon which skirts may be displayed. The face of the wheel concaves, or slopes in toward the center. White skirts, under which colored paper has been placed, may be fastened around the outside, either in the form of a circle or a hexagon, the bottoms of the skirts being at the side of the wheel. Then, almost at the center, arrange four more skirts the same as the others. Then cover the tops of the last skirts with a large, round ticket, fastened to the wheel with a hat pin, and weighted, so that the ticket will remain stationary while the wheel revolves. The wheel may be of any size, to suit your window, and should be constructed of pine or other light material. It is extremely simple, and may be constructed by any one, while, as may be seen at a glance, it is sure to be a very attractive display.
THE FOLDING STAR.
The design is a background, to be used in connection with any line of goods. When the star is closed all that fronts the spectator is a mass of white puffing. It slowly opens and reveals a recess in which is a display of goods strongly lighted by hidden incandescents. The effect is beautiful and is sure to attract attention. The back of the points, which form the star when it is opened, are puffed in yellow or some other color harmonizing with your display. Upon each point, the framework of which is shown here, is fastened a spring hinge, such as is used on screen doors. These hinges operate to close the points. Strong picture wire is used to draw back the points, and this must be fastened as near the hinges as possible in order that it may be concealed by the puffing, as it is on the face of the display, pulling the points out. By covering the hinges and wire with stiff paper, and puffing over that, a space will be left for the wire to run in and render it invisible. The pulleys at the three corners of the framework, as shown in the drawing, should be double, the wires running over them being spliced a few inches beyond the pulleys. The large drive wheel shown in the basement should be set up with one standard to allow the wires to make a complete revolution.
