This Type of Self -Propelled Truck Saves 

 Even the Labor of Unloading 



^0 the long list of uses for the efficient 

 little self-propelled electric truck — is 

 added that of general hauler around fac- 

 tories. By the simple addition of a dumping 

 body, the truck is now able to move every- 

 thing from bricks to the actual factory prod- 

 ucts, with great facility. In the small space 

 under the truck-body it carries an electric 

 motor and power plant of storage batteries. 



A load, weighing as much as a ton and a 

 half, can be placed in this little body. The 

 truckman then leaps upon the front of the 

 truck, throws in the switch and turns the 

 starting lever. This starts the truck, and 

 the cargo is sped on its way at the 

 rate of seven miles per hour. When the 

 destination is reached, the car is stopped, 

 and by means of a tripping lever 

 the body is released and dumped 

 at the proper side. The body is 

 then brought back by 

 means of roller bearings. 



When fiat or large 

 loads are to be carried, 

 the body can be re- 

 moved and the ordinary 

 platform can be substi- 

 tuted for it. The truck 

 can further be utilized 

 as a tractor. In this 

 capacity it will vfery 

 easily haul any load 

 up to nine or ten thous- 

 and pounds. 



A Needle That You Can Easily Thread 

 in the Dark 



N 



O matter how good your eyes are, there 



The thread slips through an opening in 

 the top of the needle which closes as 

 soon as the thread passes into the eye 



strain in threading a needle. If your vision 

 is not as sharp as it once was, it is even 

 something of a task to get a piece of thread 

 through a needle's eye. 



A needle has been devised which can be 

 threaded by the simple expedient of looping 

 the thread over the head of the needle and 

 drawing it downward. The needle differs 

 from the ordinary needle in that it has an 

 opening through the top of the 

 eye through which the thread 

 slips when it is drawn down- 

 ward. The steel ends 

 spring close together as 

 soon as the thread has 

 passed into the eye. 



This type of needle is 

 caid to be particularly 

 adapted to the doing of 

 fancy work because two 

 or three threads may be 

 passed through the eye 

 at one time, a feat that is 

 quite impossible with the 

 ordinary needle. It is also 

 useful for embroidering 

 with worsted, the thick, 

 clumsy threads of which 

 make it necessary, usu- 

 ally, to employ a needle 

 for the purpose which 

 has a large clumsy eye.
