Prizes for Labor-Saving Automobile 

 Improvements 



$100 for the best labor-saver and $50 

 for the next best. Read these rules 



MORE than four million Americans 

 own automobiles. Most of these 

 owners run their own cars and 

 make their own repairs. Many of them 

 have undoubtedly invented ingenious at- 

 tachments about which others would like 

 to know, and some have unquestionably 

 made improvements about which the 

 great automobile manufacturers would 

 like to know. 



All this latent, unrecognized inventive 

 talent should be brought to light, es- 

 pecially at a time when we need inven- 

 tions. And so the Popular Science 

 Monthly has decided to inaugurate an 

 automobile contest. It offers two prizes 

 —one of $100, the other of $50— to be 

 awarded in accordance with the rules pub- 

 lished below. The prizes will cover at 

 least part of the cost of patenting the in- 

 ventions. The devices which win the 

 prizes will undoubtedly be of sufficient 

 commercial merit to warrant an automo- 

 bile manufacturer purchasing the patents 

 by which they are protected. 



The main purpose of this contest is to 

 encourage automobile owners and users to 

 disclose their ideas. 



Rules Governing the Contest 



1. The device offered for consideration 



must be labor-saving in character. In 

 other words, its use must result in a 

 saving of the muscular effort required 

 to run a car or to maintain it in good 

 condition. 



2. The device offered for consideration 

 must be commercially new. In other 

 words, it must not be purchasable in the 

 open market. 



3. The device submitted by a contest- 

 ant may be a simpUfication or improve- 

 ment of an invention now incorpo- 

 rated in standard automobiles. Thus, 

 it may be an engine starter, an elec- 

 trical or hydraulic gear shift, a brake, a 

 mechanically raised body top, a me- 

 chanical clutch throw-in, etc. But 

 always, it must be commercially new. 

 The accompanying illustrations with 

 their captions will give the prospective 

 contestant an idea of the kind of 

 labor-saving device the Popular 

 Science Monthly editors have in 

 mind. 



4. Contestants are not limited in the 

 number of devices which they may sub- 

 mit. But only one device can possibly 

 win the first prize and only one the 

 second. The contest is open to every- 

 body.

Here is an excellent instance of what we mean when we speak of a labor-saving device. 

 This hood-raising mechanism does away with all muscular effort, beyond throwing a 

 lever, as it consists of a method of raising and lowering the hood by means of power 

 developed by the engine. Your drawing need not be as elaborate as this, but it should 

 clearly show essential features. We will work it up in the form here shown
