84 TRANSACTIONS OF THE 



CLAIMS FOR GOLD MEDALS— 1875. 



SECOND DEPARTMENT. 



Sacramento, October 26th, 1875. 



To the Honorable th< ('ounnittei on Gold Medals of flic California State 

 Agricultural Society : 



Gentlemen: Thomas & Bullard, of Sacramento, by this state- 

 ment, lini-i respectfully show: that at the late State Fair they exhib- 

 ited specimens of their pumps, known as the "Thomas Ever-primed, 

 Self-ventilating Syphon Pumps," the manufacture of which they are 

 now engaged in at said City of Sacramento ; that they are compet- 

 itors for the society's gold medal, offered for the most meritorious 

 exhibition in the second department, as per the society's schedule of 

 premium-. 



It is a well-known fact that the old styles of suction pumps — as, for 

 instance, the famous Douglas suction pumps — are very defective, 

 especially in a warm climate like that of California, because of the 

 shrinkage of its leather packings, consequent of the dryness and 

 warmth of climate, and the loosing of its priming through the straight 

 supply-pipe running into the well or cistern. 



It is equally well known that more power is required to operate the 

 submerged valve-pump, commonly known as the deep well or lift- 

 pump, so commonly used in dry climates instead of suction pumps, 

 than to operate a suction pump, because in the former no aid from 

 atmospheric pressure is obtained. 



It is also quite well known that the manufacturers of all old styles 

 of pumps direct that the supply-pipe be from one-third to one-half 

 the size of the working cylinder: consequently such pumps will 

 always draw sand, which, of course, wears out and destroys the 

 pump, and it- valves and plunger — when there is any sand in the 

 well or cistern. 



That on our pumps we are at liberty to use a pipe of indefinite size, 

 running into the well or cistern, and do use a pipe at least one-fourth 

 larger than the working cylinder, and, consequently, the water rises 

 therein so slow that it is an utter impossibility to cause them to draw 

 sand. Consequently, we claim that we are entitled to he awarded the 

 society's gold medal for the most meritorious exhibition in the 

 second department, upon the following grounds, to wit: 



That our pumps are always primed, and whenever power is applied 

 the water, or other fluid or liquid, will always be raised and dis- 

 charged, and windmill or other power will never be wasted upon a 

 new primed pump, nor will the user thereof ever be under the neces- 

 sity of wasting time in renewing primings. 



That because of the fact of the priming in the pump being always 

 present we are enabled to use metal packing on plunger or piston
