���Device to Remove Automobile Bodies Without Scratching Them

TWO men can remove a highly-polished automobile body from its chassis without giving its surface a scratch, by means of the device shown in the accom- panying illustration.

This new device is attached to an over- head trolley. It con- sists of two sets of ^Hum compass-like arms pivoted to the ends of a common cross- member at the top. The arms of each set may be spread out to reach the front and rear ends of the body in exactly the same manner as a compass is opened by

means of a rack and quadrant device. Each of the arms is made with a telescop- ing bottom for adjustment to the various types of bodies. Loose collars with two projecting arms are slipped over the bottom of each arm to reach underneath the side of the body and support it at unpolished points. The looseness of the collars enables them to be turned in any direc- tion or moved up or down to obtain the proper point of support.

In operation, the framework carry- ing the lifting device is moved along its trolley so that the compass arms are on each side of the body to be lifted off the chassis. The arms are then spread out and the lifting collars

���levers. It is then moved horizontally to its point of deposit. The reverse of this operation puts the body back on the chassis.

Sometimes the body must be lifted clear off the chassis frame for a height of two or three inches before the projecting arms on the lifting collars can be placed on some unpolished part. This may be accom- plished by means of a two- part bar with beveled ends, which bar is held together at the center by means of a collar or sleeve. By removing the floor- boards of the car body, the beveled ends of the bar may be inserted between the bottom of the body sill and the frame.

��An Automatic Revolver No Bigger Than Your Watch

AUTOMATIC revolvers are made about l\ as big as a standard watch.

Little as these revolvers are, they never- theless contain an automatic reloading mechanism as complete as that of any of their bigger brothers. They are "seven- shooters." Six cartridges are held in the magazines in the handle, and one in the firing chamber. The pressing of the trigger sends the firing-pin against a tiny percussion cap. The bullets are one-tenth jtgfg^^ inch in diameter

and weigh i/i oo ounce.
