The Different Positions of the Picture will Appear in Action When Turning with the Drum

It is only necessary to put the parts together, grasp the base in one hand and turn the support B with the other, when, looking through the slot E, the boy is seen pounding the stones. Various pictures can be made and the strips changed.—Contributed by C. C. Fraser, Saginaw, Mich.

Substitute for Cleats on Boards

The necessity for using more than one cleat for fastening two boards together may be done away with by using the device shown in the sketch. The center cleat prevents the boards from buckling while the sides are tightly held by these simple flat fasteners. The fasteners are made of tin cut as indicated, slipped between the edges of the boards and the parts bent over and tacked. Where the strain is not too great the holders may be used without a cleat, making an effective flat fastening.—Contributed by W. O. Nettleton, Washington, D. C.

The Metal Clips Hold the Edges of the Boards Together Closely and Quite Rigidly

Attaching Door Knobs to Locks

When putting a lock on a door it is often difficult to press the two knobs together tightly enough to prevent them from rattling and still be able to insert the screw into the shank. By using a piece of board, 1 in. thick, 6 in. wide and 1 ft. or more in length, with a V-shaped piece cut out of one side, the knobs can be easily forced and held together while the screw is inserted.—Contributed by H.
