"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
