COIL BOILERS. 



T notice that there is considerable in- 

 terest in regard to boilers constructed of 

 pipe and venture to describe a heater 

 I have planned to build. I had 

 thought of a furnace with a division of 

 fire brick running back horizontally near- 

 ly to the rear of the fire-box, dividing it 

 iiato two parts, upper and lower, and 

 causing the heat to travel as in a return- 

 flue boiler, to the back of the space 

 in the lower division and then forward 

 in the upper section to the smoke stack 

 over the front of the fire-box. Could I 

 bring in the return pipe at the bottom, 

 carry it back and up to the front of 

 the upper division of the furnace, then 

 back and down to the lower division, for- 

 ward to the front and back and up 

 through the upper division to the flow 

 pipe at the upper front! This would 

 make the water travel twice through 

 both divisions of the fire-box. Would it 

 be more practicable to be content with 

 a single coil? How could I get a tight 

 joint in the pipe? Would 10-inch tile do 

 for the stack? C. L. W. 



I fail to see how it would be possible 

 to make the design of a furnace in which 

 the two return bends are used, give 

 satisfaction. It is difficult to force hot 

 water to make a return trip from a 

 cooler to a hotter chamber, which would 

 be necessary in that case. Further, I 

 doubt if you could induce a flow of water 

 through that length of pipe exposed to 

 the action of the flames unless the pipe 

 used be two or more inches in dianaeter, 

 A large number of small (1^-inch) 

 short pipes will accomplish the purpose 

 better than the greater length and intri- 

 cate coil. 



The second plan, when the return 

 water enters the front of the fire-box 

 over the fire and passes out at the front 

 of the upper chamber near the smoke- 

 stack, is more practicable. In both cases, 

 however, it will be necessary to use mani- 

 folds in order to get suflicient heating 

 surface in the boiler to heat any con- 

 siderable amount of greenhouse space. 

 By placing the manifold to which the 

 main return is connected just over the 

 fire door, and either inside or outside the 

 fire-box, and carrying each pipe through 

 the front or out the top of the furnace 

 into a second manifold, I believe you can 

 make a satisfactory heater. 



If you use long screws and lock nuts 

 with red lead instead of unions I do not 

 believe you will have any difficulty in 

 keeping the joints tight. 



The sewer pipe will be all right for the 

 smokestack if it is in right proportion to 

 the grate surface. You do not indicate 

 the size or capacity of the furnace you 

 intend constructing. It is therefore im- 

 possible to say whether or not the 10-inch 

 pipe will be adequate. 



If you intend constructing a pipe heat- 

 er, would call your attention to the one 

 figured in the Review of December 31, 

 1903, page 269. L. C. C.

KIND WORDS NEVER DIE. 



Bellevne, Pa. 

 Chas. T. Slebert: — Please book my order for 

 100 lbs. of Zinc Never Bust Glazing Points. I 

 hare used five different kinds In the past 12 

 years, and none of tliem gave me satisfaction 

 like yours. Tbey will stay in, are easy to 

 drive, no rights or lefts, will bold the glass 

 in place, and do not rust away like all others 

 I have used. Your Zinc Points are easy to 

 take out when making repairs. I have used 

 about 100 lbs. of your Zinc Points in the last 

 two years, and am perfectly satic^ed with 

 them. Yours truly, 



F. BnRKI. " 



Cleveland, Ohio. 

 Chas. T. Slebert: — In our 25 years' experi- 

 ence with glazing points of ail kinds, I can 

 say your Zinc Points are the best to date. 

 CHAS. H. WILSON, 

 Mgr. for Grant-Wilson Floral Co. 



liockland, Ohio. 

 Chas. T. Slebert: — I must say the Zinc Points 

 have given great satisfaction. I have over 

 100 lbs. on my houses, and feel justified in 

 stating that they are the best point ou the 

 market. Yours respectfully, 



W. K. PARTRIDGE, Florist. 



_ Glenfield, Pa. 

 Chas. T. Slebert: — I take pleasure in ex- 

 pressing satisfaction in using your Zinc Glaz- 

 ing Points. They have outlasted all others 

 used, therefore are better and cheaper. Their 

 merit should result in extended sales. 

 Sincerely yours, 

 THEO. F. BECKBRT, Florist. 



Fort Wayne, Ind. 

 Charles T. Slebert: — I can truthfully say 

 your 'Zine Points are the best I ever used. 

 They are easily driven and withdrawn and are 

 stiff. Being straight on one side, they can 

 be driven accurately; consequently the break- 

 age of glass is very small. I have some in 

 ufle four years, and tbey are still in their 

 place, as good as new. 



W. S. ROEBECK. 



Springfield, Ohio. 

 Chas. T. Slebert: — You no doubt know by the 

 229 lbs. of Zinc Points we have ordered from 

 you that we consider them the best on the mar- 

 ket. We have four new houses under way, 

 each 255 feet in length, and will soon have to 

 place our order with you for quite a lot of more 

 glazing points. We are, very truly,
