machines that we have in operation, at 

 our store and greenhouses respectively, 

 save us at least twenty-five per cent 

 over the old method of using ice," says 

 Harold M. Joy, of the Joy Floral Co., 

 Nashville, Tenn. "A machine is much 

 cleaner and keeps the flowers much 

 longer. We have also found that the 

 York machine requires practically no re- 

 pairs and our oldest machine is seven 

 years old. We are of the opinion that 

 the calcium brine tubes are better to 

 hold down the temperature than the 

 brine tanks with coils in them." 



A 4-ton York refrigerating machine, 

 driven by a 20-horsepower gas engine, 

 according to W. K. Brown, superintend- 

 ent of the C. & G. L. Pennock range, at 

 Lansdowne, Pa., cools a concrete room, 

 7x12x32 feet, lined with three inches of 

 cork. He says: "The cost of operation 

 is about 35 cents per hour for power and 

 about 1 cent per hour for lubrication. 

 A 100-pound cylinder of anhydrous am- 

 monia will last several years, if the pip- 

 ing is free from leaks. It is possible for 

 us to reduce the temperature in the 

 above-mentioned room at the rate of 10 

 degrees in ninety minutes to a point 45 

 degrees above zero. Below this point, 

 however, a little greater length of time 

 is required. In this operation a brine 

 temperature of 15 to 18 degrees is main- 

 tained." Mr. Brown believes that the 

 tise of the brine tanks in connection 

 with the York machine is highly desir- 

 able and, if electricity is available, he 

 advises its use in preference to other 

 forms of power. 



Another Ammonia Machine. 



A refrigerating machine and equip- 

 ment suitable for florists ' use is manu- 

 factured by the Lipman Refrigerator 

 Car & Mfg. Co., Beloit, Wis., in which 

 anhydrous ammonia also is used as a 

 refrigerant. This machine is used by 

 a number of florists. 



"We have had a Lipman refrigerat- 

 ing machine in operation for a little 

 over two years, ' ' says H. G. Pauli, Dav- 

 enport, la. "We use about five ))ounds 

 of ammonia a year. The original cost of 

 the machine was about .$800 and tlie 

 cost of the electric wire connections 

 was approximately $85. The upkeep so 

 far is not worth mentioning. The ma- 

 chine consumes about $6 worth of power 

 per month, and the water bill amounts 

 to about $1 per month. We have no 

 brine tank at present, but are figuring 

 on building a box four times as large 

 as the one we now have. We are going 



to put in a brine tank and are sure 

 that the machine will take care of the 

 new box with little extra cost." 



"I would not care to go back to the 

 use of ice, with all of its muss and in- 

 convenience," says Harvey C. Sheaff, 

 president of the firm of Mrs. E. A. Wil- 

 liams, Inc., Pittsburgh, Pa. "We in- 

 stalled a %-ton Lipman machine in Oc- 

 tober, 1920, and arranged to cool two 

 boxes continuously, and a third one at 

 any time desired, using ammonia and 

 brine (indirect system). The little ma- 

 chine did its work well, as regards re- 

 frigeration, and, even with the lack of 

 mechanical advice and care, we found 

 we could save money. The automatic 

 features have not always worked effec 

 tively, but I have been advised that it 

 is on account of a lack of knowledge or 

 care on the part of the mechanic. You 

 can, therefore, see that ours has been 

 somewhat a matter of experiment. 1 

 have been advised that the direct ex- 

 pansion system is superior to the brine 

 tank. I would make certain, however, 

 that the engineer who sold the machine 

 or installed it, knew his business. After 

 the machine is installed and operating, 

 it is essential that some one be on the 

 ground, subject to an emergency call, 

 or it might be well to have monthly in- 

 spections, which we will have in the fu- 

 ture. Our machine is doing finely at 

 present. We have always had faith in 

 it, and would not care to give it up, 

 but it is an experiment, and a great 

 deal depends u[)on the service your sell- 

 ing agent or his engineers render after 

 the machine is installed." 



At the store of the T. J. Noll Floral 

 Co., Kansas City, Mo., a Lij)man ma- 

 chine has been in operation over two 

 years without a single repair. "The 

 cost of operation is less than one-third 

 the cost of ice," says this firm, "to say 

 nothing about the saving in space taken 

 up by an ice chamber. A 6-inch space 

 is allowed for hanging the coils on the 

 back of the icebox. The Lipman only 

 covers the pipes with frost and does 

 not form any ice, so that there is only 

 a small amount of drip. Our box is 

 7x8x30 feet, and our machine is operat- 

 ed with a 2-hor8ep(iwer motor. This ma- 

 chine holds the box at 46 degrees in 

 any kind of weather at a cost of from 

 $15 to $25 per month. Being strictly 

 automatic, the machine needs no atten- 

 tion except oiling occasionally." 



The cost of installing the machine at 

 the store of the Alpha Floral Co., Kan- 

 sas City, Mo., was about .$2,500. This 

 cools the window, eighteen feet long, 



eight feet deep and ten feet high; one 

 icebox, 8x8x20, which is all glass; one 

 wooden storage box, 8x9x20, and an- 

 other box, 6x6x16. The only expense in 

 running the machine is about $55 a 

 month for electricity, states this firm, 

 and an average of about $30 a month 

 for storage. The machine now in use, 

 a Lipman, the firm has had about six- 

 teen months and it has not had to be re- 

 charged with ammonia. "Before put- 

 ting in this machine," states the Alpha 

 Floral Co., * ' we used the city refrigera- 

 tion, which cost $300 to $400 a month. 

 Never having used ice in these boxes, 

 we couldn't say what it would cost to 

 ice so much space. The machine oper- 

 ates automatically. The thermostat is 

 set in the icebox. We think such a ma- 

 chine is the only thing for a florist, for 

 it doesn't need a mechanic to take care 

 of it. All that needs to be done is to 

 oil it once a week, in three different 

 places, which takes about fifteen min 

 utes. ' ' 



In Cleveland. 



The new store of the Jones-Russell 

 Co., Cleveland, O., which received wide- 

 spread publicity at the time it was 

 opened as one of the most beautiful 

 flower stores in the country, is equipped 

 with a 21/^-ton Phoenix ice machine, 

 made in Cleveland, which is driven by 

 a 5-horsepower electric motor. The am- 

 monia compressor is equipped with a 

 safety relief valve, which eliminates any 

 possible danger that might be caused 

 by the operator starting the machine 

 and forgetting to open the discharge 

 valve. The ammonia receiver is 

 equipped with a liquid gauge glass and 

 safety relief valve. The latter olim 

 inates the danger of explosion in case 

 of fire, for should the pressure in the 

 receiver exceed 250 pounds at any time, 

 the relief valve automatically opens and 

 lots the ammonia escape through a pipe 

 which leads to the roof of the building. 

 The machine cools the storage icebox in 

 the basement and the display cases on 

 the first floor at the back of the store. 

 The refrigerating compartment in the 

 back of the display cases is equipped 

 with three round congealing tanks 

 filled with calcium chloride solution and 

 piped with extra heavy ammonia pipe 

 coils. These tanks make it possible 

 to carry an average temperature of ap- 

 l'roxin\:itely 40 to 45 degrees. The 

 architect's drawing reproduced above 

 shows the location of and floor space 

 occupied by the ice machine and ice- 

 hoxt>s in the Jones-BnsHoll store.
