TRAVIS GREENHOUSE ROCKER GRATES 



Built for any size or style of boiler. Handles soft lump coal, which clinkers badly, also hard coal, in a first-class 

 manner, and releases the ashes without molesting the firebed. They excel any other make of grate for cleaning a coal 

 fire. It is an absolue fact that the scientific handling of a coal fire is to release the ashes and cinders beneath without- 

 disturbing the firebed. 



Our Grates will accomplish the above results. Give size of furnace and we will quote exact prices.

south end with the 3-inch line referred 

 to. It would be impossible to return 

 against the natural fall of one foot 

 in this house, would it notf Do you 

 think the boiler is large enough! 



F. A. 



The two 2-inch flow pipes and eight 

 1%-inch returns would be ample to 

 maintain a temperature of 50 degrees 

 in a house 28x150, but some change 

 must be made in order to drain the drip 

 water from the pipes. The best way 

 would be to change the slope of the 

 returns so that they would have a fall 

 toward the boiler. A less satisfactory 

 way would be to leave the returns as 

 at present and run a drip pipe along 

 each wall, which could be used to con- 

 nect the lowest part of each return 

 with the boiler. This pipe should, of 

 course, have a slight fall. 



The foregoing suggestions are made 

 with the understanding that the house 

 is heated by steam. The boiler can 

 be made to heat the house, but a 

 larger one would require less careful 

 attention. 



THBEE FLOWS PBEFEBABLE. 



I should like to get a little informa- 

 tion in regard to piping a greenhouse 

 27x62 feet and eleven feet to the 

 ridge. The side walls are three feet 

 six inches high, double boarded, with 

 tar paper between. There is glass in 

 the south end. I have a Bichmond hot 

 water boiler, with openings for a 3%- 

 inch flow and two 2% -inch returns. 

 Would a 3%-inch flow under the ridge, 

 connected with four 2-inch returns on 

 each side wall, give a temperature of

at S. A. F. Convention August 20, Chicago, 111.; also by the many 

 visiting florists who attended the convention : Close spacing of 

 the flues ; the long fire travel, making the water heat more 

 rapidly and giving the full benefit of the fuel ; also the ease with 

 which the boiler can at all times be INSPECTED and 

 KEPT CLEAN both inside and outside, which preserves the 

 life of all boilers.
