28 Inaugural Address by the President. 



Fig. 4 illustrates an electric motor arranged to drive either 

 a mangle or an ice making machine. 



At present it is connected by the strap to the mangle which 

 it drives very agreeably on washing days. By changing'^the 

 belt it may work the ice maker, the product of which was found 

 acceptable in the hot weather. You simply enclose about a 

 pint of water in the receptacle, switch on the current, and come 

 back in twenty or thirty minutes for the ice. Water or wine 

 can be iced in a very few minutes, and ice cream can be made. 



Fig. 5 shows our electric motor car, or as a friend calls it the 

 electric street boat. In it the motor and gearing are at the 

 back over the driving wheels. The accumulator to carry the 

 store of electricity needed for a 20 mile ride is under the middle 

 of the car. The steering is effected by the wheel in front acting 

 on the front wheels. 



On the table is an electrically driven meat chopper, in which 

 I have arranged a small motor simply coupled up to the usual 

 hand chopping machine. The only disadvantage m introducing 

 a machine of this kind into one's domestic arrangements is the 

 continuous monotony of croquettes and rissoles which its 

 handiness suggests to the housekeeper. By removing the 

 chopping arrangements, and substituting egg beating apparatus, 

 it is converted into a very efficient egg beater. 



When this machine had been working for a year or so in my 

 kitchen it occurred to me that the effect could be got more 

 directly and simply. The magnetic pull which drives the 

 rotary motor acts, like all other pulls, in straight lines and 

 would produce the rectilinear motion required for meat chopping 

 and Qgg beating, if we did not employ complicated means m 

 the motor to produce rotary motion which we do not want, 

 and are obliged to render rectilinear by further contrivances 

 before we can use it. 



It would be evidently simpler and better to allow the 

 rectilinear pull to produce directly rectlinear motion. This is 

 accomplished in the new form ot apparatus Fig. | (here 

 arranged as a meat chopper) in which the well known action 

 of a solenoid on a soft iron core is employed.
