Lubrication, sight feed to shaft bear- 

 ings, cylinders, pistons, cranks and 

 crank pins by mixture with gasoline 

 fuel supply. Crank encased. Fuel 

 supply by gravity system. Fuel 

 tank holds one gallon of gasoline. 

 Base of aluminum bolted to oak 

 baseboard. 



Pump, bronze rotary, 2-inch suc- 

 tion, 1^-inch delivery. Capacity 

 20 gallons per minute. 



Engine and pump are coupled di- 

 rect. The overall dimensions are 

 approximately as follows : 21 inches 

 high, 17 inches wide and 28 inches 

 long, and the combined weight, com- 

 plete with gasoline tank holding one 

 gallon of fuel, couplings for suction 

 and delivery hose, pressure gauge, 

 oak base-board and carrying handles 

 complete, ready to run, is 135 

 pounds. At first, one-inch rubber- 

 lined cotton hose was used. It prov- 

 ed, however, too heavy and it was 

 decided to use IJ/2 inch diameter 

 linen hose; 1,500 feet weighs 240 

 pounds complete with couplings. 



Tests Statisfactory. 



The method in which it is pro- 

 posed to use such apparatus is in 

 units of two or more according to 

 conditions prevailing in the terri- 

 tory in which they may be adopted ; 

 each unit relaying water by the use 

 of canvas tanks. In this manner. 

 No. 1 pump, placed at the source of 

 water supply, pumping into a can- 

 vas tank, would supply No. 2 pump, 

 which in turn would supply a third 

 outfit, and so on. Under ordinary 

 conditions, when the ground is prac- 

 tically level, two pumps, by relaying 

 should supply water approximately 

 2,500 feet from the source of initial 

 supply. In country which is rough 

 and mountainous, it might be possi- 

 ble to have No. 1 outfit deliver water 

 only 500 feet away, but 150 to 170 

 feet above the point of suction, and 

 then No. 2 outfit would relav a fur- 

 ther 1,000 feet, and 75 to 80 feet 

 more elevation, so that water would 

 be delivered 1,500 feet from the 

 point of suction at approximately 



245 feet elevation. No. 1 outfit has 

 already been used in practical work 

 in the Rocky Mountains Park at 

 Banff, controlling slash-burning op- 

 erations. Those in charge report 

 that the whole apparatus was given 

 a very fair four-day test while burn- 

 ing large piles of brush and small 

 timber and undoubtedly enabled the 

 fire to be kept within the required 

 area. Water was taken from the 

 river and pumped to points where 

 required, var3nng from 50 to 150 feet 

 above water level. A pressure of 90 

 pounds was developed and a stream 

 of water was thrown about 40 feet 

 from the nozzle. It enabled the 

 brush to be burned in large piles 

 within a clearing of 40 feet in very 

 dry weather without scorching the 

 trees. The fire was kept within 

 bounds and completely extinguish- 

 ed before leaving in the evening. By 

 holding the nozzle close to the edge 

 of the fire, a ditch from four to six 

 inches deep was made all around the 

 fire, at the same time saturating the 

 ground. Calculating the pump dis- 

 charged 20 pails of water per minute, 

 and allowing a man 10 minutes to 

 carry a pail of water over the same 

 distance pumped, a speed which 

 could not be maintained long, due to 

 the hilly nature of the country, it is 

 evident that the pump did the work 

 of at least two hundred men, thus 

 showing its great efficiency in this 

 direction, 



•i Simple to Transport. 



For the rapid transporting of the 

 outfit and necessary hose along any 

 of the roads in the Dominion Parks, 

 an automobile chassis equipped with 

 a suitable box body, into which the 

 outfit is loaded, enables any point 

 alon gany of the roads now existing 

 in the Dominion Parks to be reached 

 in a very short time. For carrying 

 over suitable trails, a specially de- 

 signed truck was built to be either 

 hauled by hand or horse power, the 

 gauge between the wheels being 

 three feet. 



The outfit can also be packed on
