THIRD ANNUAL REPORT 



ris:,ii?;?:; 



for instance, you have a spring that stands eight inches. Now 

 let that stand there alone, and the sinking away of this mass 

 will allow that to come down to ten inches. Of course there 

 is a constant pressure. Don't understand me for a minute to 

 say that that spring will add a quarter of a grain to the 

 force. It can't possibly do it. 



Mr. Root — You mean the spring will act after the screw 

 has ceased to act? 



Dr. Miller — That's the point. It is a matter of time. 



Mr. Root — Why not turn the screw down a little more? 

 Is your time so valuable? 



Dr. Miller — Just so. When I hire you I won't mind so 

 much ! 



Mr. Root — It takes so little time, the whole operation, 

 that I fail to see the advantage of the spring. 



Mr. Whitney — I simply want to nsk the Doctor if he 

 wants to hire Mr. Root? 



Dr. Miller — Yes, I am getting him trained ! 



Mr. Root — I would like to work for him. 



Mr. Starkey — We will say that this block that rests on 

 top of the wax has on top of that spring — one of the little, 

 common, coil springs like under a wagon-bed. On top of 

 that a plate that this screw comes to. If the screw strikes 

 on that spring and forces it close with this pressure on the 

 block, and goes down to where the wax is, instead of the 

 pressure being lessened this spring continues to draw the 

 pressure on this block-head to every part that has given way 

 by the wax. I think that is a very valuable point. Instead 

 of having to come back, this spring will carry the pressure on 

 four or five times, and it will save valuable time that a man 

 might be doing something else. 



Dr. Miller — Mr:„Root says it is so little time that it don't 

 count. 



Mr. Meredith — I should say a spring strong enough to 

 give that pressure would be something a little larger than is 

 used on the ordinary passenger coach. 



Mr. Root — I understand that spring would act only when 

 the screw wasn't acting. - It is their opinion that the spring 

 would do what you would do when you got back there. 



Dr. Miller— Yes. 



Mr. Root — You can't make me believe that the spring 

 would be strong enough to do what you would do. 



Mr. Starkey — We don't contend that it would do all, but 

 it would continue to exercise the pressure. If we should 

 happen back we might turn once, but you would turn four 

 times. 



Mr. Root — In the meantime, the whole operation takes 

 seven or eight minutes. 



Mr. Moore — The temptation to trip Dr. Miller up is too 

 great. 



Dr. Miller — I am down by now. 



Mr. Moore — How many tons pressure is there in that 

 screw pressing down the wax, as nearly as you can tell? 



Mr. Root — Three or four. 



Mr. Moore — You take the strongest spring you ever saw
