Buffalo Forge Company of the cooling effects of water passing through coils around or through which air was passed. As a result of these tests, a fore-cooler was constructed which practically added 50% to the capacity of the apparatus. The entire scheme was worked out in complete detail and put into successful operation.

Mr. Timmis gave the results of a test with this apparatus, made September 13, 1904. It was a comparatively dry day, the outdoor weather conditions at 10 A. M. being 67° F. dry bulb, 60% moisture, with 4.345 grains and at 3 P. M., 67.5° F. dry bulb, with 73% relative humidity and 5.28 grains of moisture per cubic foot.

The temperature of all rooms was maintained at 71° to 73° F., with the humidity at 54% to 57%, only 3% variation in the four large press rooms all day long from 10 A. M. to 3 P. M., and a variation in grains of moisture of not more than 0.06 grains per cubic foot. The average temperature of the air entering the refrigerator was 70° F., and that leaving, 51° F. The average moisture in the air entering the refrigerator was 56% or 4.468 grains, and the average moisture of the air leaving was 87%, with 3.672 grains per cubic foot. The amount of air cooled was 11,580 cu. ft. per minute. The moisture removed per minute was 1.546 lbs. and per day, 2,226 lbs. The refrigeration was equivalent to 32 tons of ice per 24 hours.

Another test made September 14, 1904, on a moist day, showed:

In reply to a query Mr. Timmis said that wherever well or running water can be obtained at a temperature of from 50° to 55° F., the desired effects can be secured as well as with a refrigerating machine.

The speaker then told how paper will change its shape before it is seasoned so that in some cases it has been necessary to run the paper blank through a press without printing in order to season it. The importance of this is seen in connection with three and four color work where a variation of 1/175 of an inch will throw the impressions out of register. He instanced a case where presses had been held up several days in the hopes that the atmospheric conditions prevailing at the time of the first impression would return.

Mr. Timmis described an elaborate installation in the plant of the Sackett & Wilhelms Co. in Brooklyn, where the equipment includes a dehumidifier, indirect

heating coils and fan. In this case the plant which cost originally $6,500, paid for itself in the first year.

Figures were also presented covering tests made by O. L. Peabody at the plant of the Forbes Lithographing Co., at Chelsea, Mass., covering variations in the stretch of paper under different air conditions. In these tests 22 samples were tested and it was found that there was considerable variation depending on the relative humidity. A variation of 15% was quite common and 25% not unusual.

In most printing shops where there is no special provision for air control, it is customary to see a rise of relative humidity during the morning hours of about 9%, followed by a falling off during the noon hour and another rise in the afternoon. This is supposed to be due to the evaporation which takes place from water used for wetting the stones in the printing plant.

In discussing the subject Mr. Lyle instanced the case of a New York printer who, during a particularly hot and humid week in New York last summer, was the only printer in the city doing color work. The result was that he was swamped with requests for help from other printers whose plants were not provided with air conditioning systems.

Before the meeting came to an end, Mr. Timmis showed how a home-made hygrometer could be made in 10 minutes which would be found exceptionally accurate. Take a milk thermometer, he said, and attach it to a string. Then fasten a wet strip of cloth to the bulb and whirl it around at a velocity of about 500 ft. per minute. Compare the temperature with that of a dry bulb thermometer and the relative humidity can then be determined very accurately.

Illinois Chapter on Steam vs. Hot Water Heating.

"Forced Circulation of Hot Water vs. Direct Steam Vacuum Heating for Industrial Plants" was up for discussion at the December meeting of the Illinois Chapter. Two committees led opposite sides in the debate, the vacuum steam heating interests being in the hands of E. B. Gordon, chairman; W. A. Green and John D. Small, while the forced hot water advocates were led by R. A. Widdicombe, chairman; W. R. Graves and August Kehm.

The well-known advantages of both systems were dwelt on and, in addition, many instances were cited where conditions favored one or the other type of installation. For instance, R. A. Widdicombe brought. out the point that where a plant is new

and where the conditions may be expected to be permanent, the use of hot water has obvious advantages in respect to economy and regulation. On the other hand, E. B. Gordon, Jr., showed that where flexibility is an important feature or where extensions of the system are contemplated vacuum steam heating has the advantage. Other speakers were Messrs. W. A. Green, W. B. Graves, J. D. Small, E. F. Capron, J. F. Tuttle, George H. Kirk, N. L. Patterson, William Lees.

Previous to the discussion, J. H. Davis gave details of the work planned by the Chicago Ventilation Commission. This includes a series of cabinet tests in which subjects will be confined and their condition noted with various amounts of air supply, etc. Other plans of the commission include tests of occupied and unoccupied moving picture theatres. Still another feature of the work will be tests with ozone machines to determine their effect in purifying the air and in neutralizing odors. The chapter voted an appropriation of $50 towards the work of the commission.

President H. M. Hart, presided at the meeting. Three new members were elected: E. J. Coffy, Harry M. Nacey and Frank J. Douglass. W. E. Marquam was elected to associate membership.

American Society of Mechanical Engineers.

A record-breaking registration marked the annual meeting of The American Society of Mechanical Engineers in New York, December 2-5, 1913. There were 794 members and 504 guests present. A feature of the meeting of interest to the heating trade was the spirited discussion over the report of the Committee on Standardization of Flanges. This report embraced a schedule known as the "1914 Standard," which was a compromise of the 1912 U. S. Standard, adopted in that year by the mechanical engineers' society and the National Association of Master Steam and Hot Water Fitters, and of the 1912 Manufacturers' Standard.

The compromise had already been tentatively agreed to by all of the parties interested except the master steam fitters' association. Strong objection to the adoption of the compromise was made by that body through its representatives in at

tendance, the point being made that the 1912 U. S. Standard has already been adopted by various departments of the Government, as well as by a number of manufacturers. It was also held that if a compromise schedule should be adopted, the interchangeability feature of the 1912 U. S. Standard should be retained and that it should be known as the "1912 U. S. Standard Revised to January 1, 1914," instead of the "1914 Standard."

The committee representing the mechanical engineers, whose spokesmen were H. G. Stott and W. M. McFarland, showed that the purpose in the new schedule was to effect a compromise that would best serve the interests of all concerned, as the difficulties of having two standards in operation was apparent.

When the matter came to a vote, it was decided to postpone definite action on the new standard until the next meeting of the society. In the mean time an effort will be made to compose the varying opinions of the different interests.

As previously noted, one of the papers presented at the meeting described "Tests of Vacuum Cleaning Systems," and was presented by J. R. McColl, of Detroit.

New officers were elected as follows:

President, James Hartness, Springfield, Vt.; vice-presidents, Henry L. Gannt, New York; E. E. Keller, Detroit, Mich.; H. G. Reist, Schenectady, N. Y.; managers, A. M. Greene, Jr., Troy, N. Y.; John Hunter, St. Louis, Mo.; Elliott H. Whitlock, Cleveland, O.; treasurer, William H. Wiley, New York.

INDUSTRIAL OZONATOR.
One Two-Unit Bank.

erating units are cast-iron boxes, provided with ozone-producing tubes. An electric discharge takes place between the inner enameled steel tube and the outer glass tube. Air is passed through the machine between the inner and outer tubes, where it becomes ozonized, and thence is carried through the piping to the point of application.

The ozone generating units are supported on structural steel frames, two units being mounted on a single frame. A transformer is employed for raising the voltage of the line to that required. As shown, it is placed within one of the supporting frames underneath the generating units. The transformers are so arranged that the voltage of the high tension current supplies to the machine may be varied at will, and the

ozone output of the generator thereby regulated.

The air filter consists of a sheet metal box through which the air passes before enter-ing the air chamber. In its path through

the filter the air first passes over a bed of calcium chloride for removing the moisture and thense through a fine screen and a layer of cotton waste to screen it of dust and dirt. If a supply of air at suitable pressure is not available, a motor-driven blower is supplied as an integral part of the equipment.

Held Ozone Air Purifier.

A new ozone machine, recently placed on the market, is the Held ozone air purifier,

HEATING AND VENTILATING MAGAZINE for October, 1913. The fans used in this apparatus are of the same general design as those used in removing grain from the holds of ships, for carrying dust and shavings from woodworking machinery, and in many other operations in industrial plants where large and fairly heavy particles are to be moved. In detail, they have been especially designed for vacuum cleaner work.

It will be noted from the illustration that the position of the fans is at the top of the casing where they are rigidly secured to the motor shaft. A feature of design secures ample clearance between the moving parts without loss in efficiency. The air is filtered through an inverted bag, the dust falling into a removable dust pan while the clean air passes away

made by the Held Co., Chicago, Ill., a standard outfit being shown in the accompanying illustration. The Held Company has for some time manufactured the Held ozone water sterilizer for water which is intended to be located above a fresh water faucet and connected to the lighting circuit. Another connection from the ozone generator leads to an ozone mixing chamber at the faucet. The success achieved with this device gives assurance of the efficiency of company's newest product for purifying air.

New Type of Western Electric Sturtevant Vacuum Cleaner.

The accompanying illustration shows the latest model of the Western Electric-Sturtevant stationary vacuum cleaner, the general principles of which were described in THE

through an exhaust pipe. The bag is kept constantly in motion by the air currents to shake off any dust that might cling to it and thus choke it.

The electric motor operating the fan is emphasized as one of the most remarkable features of the cleaner. It is arranged so that the power consumed is entirely governed by the work being done, and it is not necessary to keep the motor running while getting ready or while moving from room to room. Switches from which the cleaner may be started or stopped can be located wherever desired, affording a means of saving power and steps.

New Quarters for the Sims Company. The accompanying illustration gives an interior view of the new, modern plant of the Sims Company, Erie, Pa., whose products include feed water heaters, hot water generators, laundry heaters, special heaters of all kinds where steam is used as a means of heating; also steam separators, exhaust heads, oil filters and steel storage tanks. The new building is located at Whitley Avenue and 18th Street and is 100 x 200 ft., of steel frame construction, with concrete foundation, brick and hollow tile walls, with steel window frames. There is a 30-ft. gallery around three sides of the building on which the sheet iron products are built, and a portion used for storage purposes. A railroad spur runs through the entire building, which, together with a 15-ton crane and a 40-ft. span, provides the necessary facilities for the handling of the products. The plant is a striking illustration of the company's rapid growth, its old plant at 20th and Holland Streets being now far too small to accommodate its business.
