The Ohio Brass Company.
The Ohio Brass Company of Mansfield, O., has recently greatly extended its manufacturing facilities with a view of extending its street railway and electrical trade. The company is not new in the field, having manufactured for several years an extensive line of goods for a large western supply house. The officers of the company are well-known Ohio business men, the president being Mr. E. T. Cook and the secretary and manager, Mr. F. B. Black; while the company is represented on the road by Mr. C. K. King. Mr. King was formerly connected with the Ansonia Electric Co. and has an extensive acquaintance among the street railway men of the west.
The company has a well equipped foundry and machine shop and a laboratory equipped with everything necessary for testing including Riehle testing machines and a line of electric meters and testing sets to make exhaustive tests and measurements of the different articles placed on the market. The company intends to issue reliable reports of tests made on the various articles manufactured including the breaking strain and insulating resistance of each article so that the engineer in charge of a road will have reliable data before him.
The accompanying cuts illustrate several of the specialties of the company. In Fig. 1 is shown the Mansfield strain insulator which in the medium size has a breaking strain of 10,000 pounds. It consists of two steel staples five inches long, three-eights of an inch in diameter, moulded into a special insulating compound. It is but seven inches long and weighs but three-quarters of a pound. Its insulating properties are-guaranteed under the severest strain.
In the wood break strain insulator, shown in Fig. 2, the hard wood thoroughly seasoned and boiled in paraffine and further coated with a preservative compound furnishes the insulation between the two wires. The metal caps are securely fastened to the wood by a cone shaped wedge inside the cap being forced into the end of the wood and the fibers further coated with a preservative compound furnishes the insulation between the two wires. The metal caps are securely fastened to the wood by a cone shaped wedge inside the cap being forced into the end of the wood and the fibers completely filling the cap so that it is impossible to separate them without breaking the wood.
A strong and simple pole rachet, known as Wood's self-locking rachet, is shown in Fig. 3. It makes a very light and durable span wire tightener. It is automatic and holds securely the slack as fast as it is taken up. It can be used on either side of the pole with equal success. A malleable iron casing covers the pole rachet thoroughly insulating the span wire from the pole. It is made to strap to the pole, but can be furnished with a hole in the back at the casing for an eye bolt if so desired. These necessary parts of every overhead trolley have been designed after carefully studying the wants of the trade. The simplicity of the different apparatus together with their evident strength and durability are points that should commend them to the trade.
