"Transfer, Please," Is Answered by Use Your Ladder Properly and

Avoid an Accident

��An Automatic Machine

AN inventor has taken out pat- ents on an auto- matic transfer issu- ing machine that can deliver transfers at the rate of sixty per minute.

On top of his ma- chine are a number of individual buttons which represent either intersecting car lines or other transfer points. By pressing one of these buttons and operat- ing a foot lever, the proper transfer is de- livered. It is punched with the month, day, hour and line to which it is issued.

The transfers are supplied in small rolls of five hundred or a thousand. As each transfer is issued, it is recorded by the machine, so that the auditing department always has an ac- curate check on the conductor.

���This machine issues transfers at the rate of sixty a minute and records the number issued

��II KE all other accidents, those caused ^ by ladders are divided into two classes: those due to unsafe equipment and those caused by unsafe practices. Look at the accom- panying photographs and you will see some very common causes of ladder accidents. How often have you misused your ladder in one of these ways? There are means by which you can safeguard the base of your portable lad- der. Metal points, lead -coated plates and carborundum have been found to serve very well. The state of Pennsyl- vania goes so far as to make it a legal obligation to have a man at the foot of each ladder when the floor is of iron. Pivoted lead shoes are recommended for concrete floors and rubber bases for wet floors.

���Have you misused your stepladder in one of these ways? To use a half opened ladder, a ladder elevated on bricks or one placed on a movable platform, is to court sure disaster
