TRAVIS ROCKER GRATES 



For Greenhouse furnaces of all sizes and styles. 



Installed without altering brick work or attaching to the 

 fire front. 



The shake lever is located inside the upper portion of the 

 ashpit door. 



They have the interlocking finger which forces open all the 

 air spaces. 



Air is admitted evenly through every opening. 



You can keep your fire down thin as desired. They do not 

 dump the cinders, but they grind them through. 



They will not mix the fire and cinders together, which des- 

 troys the burning action of the fire. 



They grip the cinders and grind them through without dis- 

 turbing the bed of the fire. 



Never use a poker in your fire. Never use a grate that will 

 break the fire from top to bottom and roll it around, as this 



will cause large, hard cinders. Just stop and consider how cin- 

 ders should be treated. 



All firemen know that every time they disturb the cinders 

 they are in trouble. 



Firing on TRAVIS GRATES is a pleasure, because they re- 

 auire but little shaking. 



The cinders are reduced in bulk, and he has much less to 

 contend with than if ho were using straight bar grates or 

 wrongly constructed rocker grates. 



WE HAVE THE SYSTEM. 



Don't mix your fire and cinders together and expect the best 

 results. Gently remove the cinders from below the fire until 

 you get the reauired draft. Then you will see results that will 

 convince you that firing is not so hard AFTER ALL. 



Our only occupation is manufacturing rocker grates. For 

 prices and full information give length and width of your grate 

 surface.

under the benches, of which there are 

 three. The main headers are in the 

 center of the house and the piping is 

 all 2-inch. This supplies all the heat 

 in the center of the house, leaving the 

 ends cold. The boiler is in a pit. 



Enclosed you will find a sketch which 

 shows the details of the piping and the 

 connection with the expansion tank. 

 There are six coils under the middle 

 bench, the full length of the house. 

 There are three coils under each side 

 bench and four coils on each side wall. 

 The heating contractor ^covered the 

 main headers with asbestos, so as to 

 keep the heat down in the center of 

 the house. J. S. — Pa. 



There is nothing either in the de- 

 scription or in the accompanying sketch 

 to show where the boiler is located, but 

 since the boiler is eighty-eight feet 

 from the main headers, which are in

the center of the house, it would seem 

 that it must be some fifty feet away 

 from the house and probably at one 

 end. The size and number of pipes re- 

 quired in a gfienhouse will depend 

 largely upon the temperature to be 

 maintained, and we do not find any 

 statement regarding it. 



For 60 degrees, from 450 to 500 

 square feet of radiating surface will 

 be needed and we would supply it by 

 running three 2-inch overhead flow 

 pipes from the end nearer the boiler to 

 the farther end of the house, placing

 about three feet below the ridge, and 

 running them downhill at the rate of 

 one inch to ten or twelve feet. At the 

 farther end of each flow pipe connect 

 it with a coil of 2-inch return pipes.
