Arthur Sweet's Latest Invention

A Heater for Steam Boilers that is a Winner

Highly Endorsed

By Experts--Claimed to be the Most Economical and Practical Heater Ever MAde

Arthur J. Sweet, of this city, hass invented a water heater for steam boilers that bids fair, if it fulfills the claims made for it, to become universally used and prove a very profitable investment for Mr. Sweet.

Not only is the new invention a departure in form and plan from those now in general use, but it involves the new application of au old principle--that of vacuum-- to perform the work usually given the engine to do.

Mr. Sweet's invention is for the purpose of heating the water supply in steam boilers and removing all oil, lime and other impurities from it, thus preventing scaling and corrosion of the boiler. The invention is known as the Syphon Heater and consists of a tank about two feet by three feet and three inches thick made of iron or steel and two two-inch iron pipes which are connected with it at the top. In practical operation the appliance is connected with the water supply and the exhaust from the engine so that they enter a two-inch pipe at the same point. On the end of the water supply pipe there is a device for converting the water into a fine spray. The steam striking this is rapidly condensed, thus making a partial vacuum in the exhaust pipe and causing a suction from the engine and consequently an almost free exhaust. The water continues its way through a series of pipes in conjunction with the steam until it enters the tank heated to a temperature varying from 210 to 212 degrees Fahrenheit. During its passage through the pipes the oil contained in the condensed steam adheres to the surface of the pipes as does the lime and other impurities and when it reaches the tank ready for the boiler is absolutely pure.

This is a somewhat technical explanation of the device, but yet it is so simple in its action that a mere boy could handle it. The accumulated impurities gathered in the pipe remain in a soft state for some time, consequently it is desirable to clean out the heater and get rid of them. This is done by opening a cock at the bottom of the tank when every impurity runs out.

Mr. Sweet has been working on the invention for the past seven years and is still working to improve it. He has had one of them in operation on the boiler of the Peninsular Manufacturing Co. for the past seven months and it is working to perfection, heating the water perfectly and removing every particle of impurity so that, it is claimed, not an ounce of scale could be found in the boiler. The heater in use has been inspected by scores of practical men who are loud in praise of its practicability and economy. It has also received the unqualified endorsement of boiler insurance men and is the only heater ever recommended by an insurance company. The water cleansed by it has also been tested by chemists and pronounced absolutely pure, and is being used in the city, instead of distilled water, by druggists and others.

Mr. Sweet has associated with him his brother, Geo. W. Sweet, the feed man, of this city, and Sidney Smith, an expert M. C. engineer, forming the Sweet Syphon Heater Co., and expect to begin the manufacture on an extensive scale as soon as a location can be secured. They have not, as yet, decided whether the manufacturing will be done in this city or not. Several cities are already offering inducements to have them locate in their midst, one city--through an engineer who is acquainted with the merits of the heater--having offered a bonus of $10,000.

The gentlemen associated with Mr. Sweet have every confidence in the heater and make claims for it which, while they may appear extravagant, they say can be fully substantiated. They claim for it: That it is the most economical heater made, heating the water with less loss of energy in the engine than any other; that it will absolutely remove impurities and oil; that it requires less attention and care than any other and that it can be sold cheaper than any other.

The one in use on the Peninsular Manufacturing Company's boiler is one of the first manufactured, but Mr. Sweet has just drawn designs for another form which while it retains the same principles yet he thinks will prove even better in practical work than the present one.

Mr. Sweet is no novice in the inventive field as he is the inventor of what is known as the street railway drill an appliance which has saved the railway companies hundreds of dollars and is in use not only in America but in most of the countries of Europe.
