Firing on Clean Grates is a Pleasure 



The TRAVIS ROCKER 

 GRATE METHOD 

 of handling a coal 

 fire 18 undisputed 



It is easy and re- 

 quires but little coal 

 during the first one or 

 two hours. As the air 

 spaces begin to bridge 

 over with cinders, the effect is the 

 same as when closing the damper door, 

 and the longer you fire the more coal 

 it requires to make the same amount 

 of steam. 



The TRAVIS ROCKER GRATES 



have the mash fingers, and the air 



space cannot bridge over. They will 



remain open and free from twelve to 



twenty-four hours. Figure the amount of coal that can be saved with perfectly clean grates. A saving of only twenty-five cents 



a day for five months would amount to $37.50. Figure again. Change 

 from lump coal to slack. Note the difference in your expense for the 

 winter months. We guarantee our grates to successfully use slack, 



We make them to fit the largest and smallest 

 furnaces. They are installed in a few minutes' 

 time without the use of tools. There is a dif- 

 ference in rocker grates, even though they look 

 the same. OUR CATALOGUE will SHOW YOU 



Shown wide open, complete with hand lever. Its construction is unquestionably superior to 

 any other style of grate. The only grate that opens all air spaces when operated. Isn t that 

 just what you want? 



This is a small grate mounted on our specially made stand for 

 cast boilers that do not have grate supports. Grates will free them- 

 selves readily and will not become clogged when opened wide. •

the side benches or upon the walls. In 

 case a generator is used, the flow pipe 

 could be 2-inch and ten returns would 

 answer. If it is preferred to use 1%- 

 inch pipe for the flows, place one upon 

 each of the wall plates and connect 

 with the coils at the east end of the 

 house, and use a generator. 



A SMALL TEXAS GBEENHOUSE. 



I enclose a sketch of a small green- 

 house, 25x30 feet. "Will you please tell 

 me the cheapest way to heat itf I have 

 a Wilks hot water boiler, 24x42. The 

 south end of the house is boarded up; 

 the north end is protected by the boiler 

 shed. The side walls and the roof are 

 made with two rows of 16-inch glass 

 that extend nearly to the ground; then 

 there is a space of thirty-two inches 

 covered with felt roofing over 1-inch 

 boards; then two more rows of glass, 

 and so on until the house is all cov- 

 ered. The house is five and one-half 

 feet high to the eaves and eleven feet 

 to the ridge. 



There are four benches and I wish to 

 use the space under them for plants. 

 About half the house is for ferns; the 

 other half is for mixed plants. Usually 

 the outside temperature here does not 

 drop lower than freezing point, even at 

 night, but there are occasional bliz- 

 zards that are decidedly cold and that 

 last a few days at a time. There are 

 four ventilators at the ridge of the 

 greenhouse and four ventilators in each 

 side wall, below the benches.

From the description given, the house 

 appears to be 25x30 feet, with one-half 

 of the roof and sides covered with

To heat this house to 60 degrees, run 

 a 2-inch flow pipe under the ridge and 

 two 2-inch returns from the farther end 

 of the house back to the heater, pass- 



ing under the west bench. The sketch 

 shows two doors in the east wall of tUe 

 house, making it impossible to run two 

 other pipes along the east wall. The 

 best that can be done is to run one re- 

 turn under each of the benches.
