| TEXT | The Smooth-On Manufacturing Company was founded to manufacture a chemical iron compound, known as Smooth-On. Its officers are Samuel D. Tompkins, president; Vreeland Tompkins, treasurer; J. Haviland Tompkins, secretary. The history of Smooth-On, while not very old, is rather interesting. This chemical iron compound was made in 1893 by Vreeland Tompkins, a chemical student and graduate of Rutgers College, the object being to make a chemical iron that
could be easily applied to cracks and holes in iron to make permanent repairs. A compound to make such repairs must metalize practically as hard as iron. It must expand while metalizing, so as to completely fill any opening into which it is introduced and also force itself into the grain of the iron. When metalized, it must expand and contract the same as iron. After two years' work this was accomplished and a chemical compound made and named Smooth-On, which forms the base or starting point for the different Smooth-On iron cements. The above properties make
Smooth-On a valuable compound for making chemical iron cements, and to this subject the chemist of the Smooth-On Manufacturing Company has given careful study for twelve years and has succeeded in compounding the valuable iron cements known so generally throughout the world as Smooth-On. Smooth-On Iron Cement was first prepared only in powder form and used by mixing with a certain percentage of water, to the consistency of stiff putty and immediately applied to cold metal, as it metalizes rapidly, in a few hours becoming as hard as iron, with the same color and
appearance and the same power of expansion and contraction. This cement, while very useful where small amounts of cement were required, necessitated a hurrying of the work when handling large quantities of the cement to get through before the cement got too stiff or hard to work. By further experiments a solvent was found for the above cement which would evaporate upon the application of heat. This enabled Smooth-On to be prepared and kept in paste or fluid form, until wanted for use. The fluid preparation of Smooth-On greatly enlarged its use, as this cement may be applied to hot or cold metal. There are now six Smooth-On preparations, each made for a special purpose:
Smooth-On for foundrymen, the first Smooth-On iron cement made, is for removing blemishes from iron or steel castings and is used for such purposes by the largest iron and steel manufacturing concerns throughout the world.
Smooth-On Compound for engineers, the second of the Smooth-On iron cements is for making repairs on steam or hydraulic work, when the application can be made to cold metal. One example will show the value of this cement.
Seven years ago the seven million gallon centrifugal pump at the New York Navy Yard split almost in two, due to a
sudden strain. The crack was twenty feet long, and it was ascertained from the makers of the pump that it would take twenty-six weeks to produce duplicate castings to replace the broken parts. It was suggested by the engineer in charge, who had used Smooth-On compound, that he could repair the pump with this cement, and permission was given. It was repaired successfully in three days and is still giving perfect service. This repair saved thousands of dollars for the U. S. Government and made a reputation for Smooth-On compound and the engineer that applied it. The third Smooth-On iron cement placed upon the market is Smooth-On joints. This cement is for making joints on cast iron hub joint pipes. It makes a very strong and tight joint and one that will stay tight. This cement was used on the hub joints at the New York State buildings at Poughkeepsie, N. Y. Smooth-On elastic cement, the fourth Smooth-On
product, was a great step forward in the compounding of iron cements, as this cement is prepared in fluid or paste
form and kept in that state until it is wanted for use, by packing in air-tight cans. This fluid cement will run into very small cracks, holes or seams, filling them with iron and by many it is called magic iron. A can of this cement may be purchased in nearly every sea port of the world, as it is universally used by steamship engineers, for making permanent repairs. The following is an interesting example showing the value of this cement: At the time of the Spanish war the U. S. transport McPherson arrived at Jersey City from Cuba with leaking seams in her boilers.
To stop these leaks in the ordinary way would have delayed the sailing of the ship. By applying Smooth-On elastic cement to the boiler seams the leaks were quickly and permanently stopped and the steamer sailed on scheduled time. The fifth Smooth-on specialty, Smooth-On iron cement sheet packing is a combination of Smooth-On iron cement No. 1
and rubber. The Smooth-On in the packing has the same action as when in the powder form, namely, of expanding slightly when it comes in contact with steam, hot or cold water. This makes it a valuable packing, as it completely fills any uneven places in the flanged faces, making a perfect joint instantly. This packing is extensively used in the engine room of the Brooklyn Bridge. The Sixth Smooth-On specialty is the Smooth-On coated corrugated steel gasket. It is made from specially prepared mild, tough steel, stamped with concentric corrugations and then coated with Smooth-On elastic iron cement. For flanged joints, they will withstand any pressure or temperature that the pipe will stand and are not affected by steam, water, oil, air or ammonia. The above gaskets are being successfully used under 3,000 lbs. pressure in hydraulic mining. One example will show their value: The De Lamar Copper Refining Co. report as follows: "The Smooth-On coated corrugated gaskets which we installed throughout our high pressure piping have been entirely satisfactory, and have been the only gaskets which we have found so far which will stand superheated and saturated steam applied alternately." |
