STANDARD Pumping Engines 



WILL SAVE YOUR TIME, MONEY AND COAL. 



This is especially true during the summer season as the amount of coal burned and 

 the time lost in getting up steam will pay for the machine. It can be started instantly, 

 uses little fuel and the expense stops when vou stop pumping. They are simple and 

 EASY TO OPERATE, POWERFUL, DURABLE and RELIABLE. 



On exhibition and tor sale in the principal Cities. 



Our catalogue and further information will be sent on request.

THE BETTER PLAN, 



"Which of these two systems of heat- 

 ing with hot water is the better? Euu 

 a 4-inch main to the far end of the 

 house and drain with runs of 2-inch 

 pipes under each bench into a 4-inch 

 return at the lower end of the house. 

 Or run a 4-inch flow along the lower 

 end of the house, have a 2-inch outlet 

 from the main supplying n coil of 2-inch 

 pipes under each bench, coming back 

 into a 4-inch return beneath the floor. 

 Is 2-iuch too large pipe for the heat- 

 ing coils? J. C. F. 



The 4-ineh main, or riser, will give a 

 less restricted flow than the 2-inch. It 

 will also give a little more radiation 

 than the two 2-inch pipes. If it is de- 

 sirable to get the greatest efficiency and 

 the greatest radiation, the 4-inch pipe 

 will prove most satisfactory. In hot 

 water heating with an open circuit it is 

 customary to nse flow and return pipes 

 of the same size, usually 3 or 4 inch. 

 With hot water under pressure the coils 

 are frequently made from IVi-inch pipe, 

 and the flow pipes in proportion to the 

 amount of radiation to be supplied. 

 Two-inch pipe is not too large for coils. 

 The size of the pipe is not of as much 

 moment as the square feet of radiation. 

 Neither the size of the house nor the 

 number of feet or heating pipe are 

 stated, so we cannot .judge of this pro- 

 portion. L. C. C. 



PIPING. 



How much 2-iuch pipe willTje required 

 to heat a house 16x100? North gutter 

 is six feet, well protected, south wall 

 four and one-half feet with eighteen 

 inches of glass: both ends glass, nine 

 and one-half feet to ridge. Winds from 

 the west are coldest. S. & B. 



To maintain a temperature of 70 de- 

 grees in the house mentioned with hot 

 water at ISO degrees it will require 

 twelve runs of 2-inch pipe the full 

 length of the house. This house requires 

 750 feet of radiation, to supply which it 

 requires 1,200 lineal feet of 2-inch pipe. 

 If the water is not maintained at 180 

 degrees, but runs about 160 degrees, it 

 will require more piping. Fifteen runs 

 the full length of the house will then be 

 required to hold the temperature at 70 

 degrees. The purpose for which the house 

 is intended is not specified, so I have 

 assumed that 70 degrees would be the 

 maximum temperature required.

The WOLF IMPROVED SYSTEM 



BJENTILSTING 

 APPARATUS 



Is now operating houses 50 to 740 feet long and is especially adapted to 

 the present style of commercial greenhouses. Is the only system that has 

 proven successful in raising the sash uniform on very long houses, using only 

 one machine, operating from either end or center of house, opening sash on 

 one or both sides of ridge pole, from either top or bottom. Less machines are 

 required, convenience and labor saved in the operation of same, lightness and 

 durability combined. 



If you are building a new range and need Ventilating Apparatus of any 

 kind and desire to purchase the most economical machine, estimates will be 

 furnished you with a 10-year guarantee, based upon actual results obtained 

 after seven years' experience in the operation of long houses. The heaviest 

 single line of sash raised by one single machine is equal to one continuous 

 sash 22y}4 feet long by 4)^ feet deep. Send dimensions of your houses, with 

 number, size and position of sash. Prices and catalogue which contains a 

 large list of references will be sent you by return mail.
