The little toy elevator that I have planned for you this week is one of the simplest mechanical toys that you can make, yet, after you have completed com-pleted it and set it in operation, your friends will be puzzled for several minutes min-utes to know what makes it run both up and down. Get a packing-case about 3 feet 6 inches high for the building. The width and depth may be of almost any dimensions. Also get enough box boards for floors and partitions. The floors are made of two pieces (A and B, Fig. 3), so It will be easy to saw out the opening for the elevator. This opening should be about 5 inches square, Mark out and cut the boards for all of the floors at one time, and be caroful to get the shaft opening the same for each floor. Cut the notch C in board A about 1 inch square. Fasten the floor boards in place with nails driven through the sides of the box. F1g. 4 shows the pattern for the partitions. The elevator car should be constructed con-structed as shown In Figs. 6 and 7. This is made out of a cigar-box. The front portion (D) should be about 3 Inches high, and the rear portion (E) should be of the same width, 2 Inches deep, and 2i inches high. Fasten these upon the base piece F as shown. Bore the holes G through the top Fig. 1. Toy Hotel with Elevator and bottom of the car, close to the sides, for guide wires H to run through (Figs. 6 and 7). These may be bored with a screweye if you haven't a gimlet or drill. Bell wire, or almost any wire that you have on hand, will do for the guides. Fasten two screw-eyes into the under side of the top of the shaft, the same distance dis-tance apart as holes G, and in the proper position so they will come exactly ex-actly over them (I, Fig. 6). Use the car to determine these measurements. Then bore two holes through the bottom bot-tom of the shaft directly below the screweyes (J, Fig. 5). Attach the wire to one screweye, run it down through holes G in the car, through one of the holes J, then across to and up through the other hole J, up through the other set of holes G in the car, and attach to the second screweye I. The elevator is lifted by means of cord L (Figs. 2 and 6). This Is fastened fast-ened to a tack In the top of the car, Inches wide, 2Mi Inches deep, and 4 run up over spool M (Figs. 5 and 6), over spool N (Fig. 2), and tied to weight K. As you will see by looking nt Fig. 5, spool M turns on the axle P in'! the ends of this axle are cut to fit snugly In screweyes I. Weight K is concealed In the smokestack fastened to the back of the building (Fig. 2). This is made out of cardboard card-board mailing tubes Joined end to end. Bore a hole through the back of the building for cord L to run through (P), and cut a hole through the smokestack at the same height. Then fasten spool N in -the stack by means of a wooden axle, as shown in the small drawing above Fig. 2. A small glue bottle, ink bottle, or medicine bottle may be used for weight IC. Fill it with sand or salt to make It heavy, cork it up, and screw a small screweye screw-eye into the cork to tie the cord L to. When the weight and cord have been adjusted, fasten the smokestack to the back of the building with wire straps; brace the top as shown In Fig. 1. If the worlf has been done carefully, careful-ly, the car will run smoothly from the first floor up to the roof. To make It drop to the first floor again, the weight Q is necessary (Figs. 2, 5 and 6). A bottle heavier than the combined com-bined weight of bottle K and the car must be procured for this; also huni Up a hook about 2 inches long (R, Fig G) and a rubber band. After filling the bottle, cork It up and screw a screweye Into It. Screw the hook into the roof of the building directly over the center of box E of the elevator, and attach one end of the rubber band to the hook and tack the other end to the top of the elevator shaft. Now, when the car runs to the top of the shaft, the bottom of the rear portion (E) will strike bottle Q, raise it enough to release the end of the hook, and the rubber band will spring the hook out of the way (Fig. 2). The bottle will then remain upon the rear portion of the car and carry the car to the bottom of the shaft. To make the car rise to the top again, It is only necessary to remove bottle Q. Replace Re-place it upon the end of hook R. Cut holes Y and Z In the side wall of the shaft for hand holes through which to reach bottle Q and hook R. Figs. 2, 5 and 8 show a simple brake arrangement for stopping the car at the different floor levels. Stick S may be a piece of broom handle, curtain pole or flag staff. Bore a hole through the bottom of the shaft, directly di-rectly below holes C In the floors (T, Fig. 2), and -slip the stick through hole T and into slots C. Then locate on one side of stick S points Just below be-low the under face of each floor, and upon the opposite side locate points just above where the back edge ol the elevator would come when the car is raised to each floor level. Re move the stick and drill or bore a small hole at each point marked; then replace it, nail a small block (U, Fig. 5) across the top end to hold It in -place, and drive a nail into each ol the holes. Now, if the stick Is turned in the position shown in Fig. 2 while the car is going down, the first nail below the car will bring It to a stop; and If the stick is turned In the oppo site direction while the elevator is going go-ing up the first nail above the car will bring it' to a stop. These brakes are controlled by two levers (W, Figs. 2 and 5). Cut these as shown In Fig 8 and screw one to each side wall Tack a piece of cord to stick S, wrap, the ends of this once around the stick, slip them through screweyes V In the side walls, and tie to tacks Id the levers. One series of brakes can now be set by pulling forward one lever, and the other series by pulling forward the other lever. . By driving a nail Into stick S at X, and a nail Into the bottom of the shaft, each side of stick S, the levers will turn the stick Just enough in each direction to bring the brakes Into position.
