New Enclosed Switch be attached to the switch handle, permitting the operator to open or close the THE accompanying cut shows a type switch from any position along the ma upon the market, which possesses several valuable and novel features. The entire apparatus is enclosed in a fireproof case, which allows the use of open-link fuses without the danger of the fuse metal being thrown about in case they are blown. The fuses form part of the switch blade, and may be so connected as to be dead when the switch is open. It is, of course, well known that link fuses are cheaper to replace than enclosed fuses. With the double-throw switch, when used for starting induction motors, induction motors, heavier fuses may be used for the starting side than for the running sidewhich is an advantage not possessed by any other form of switch now on the market. The whole combination is mounted on a slate base and enclosed in a fireproof case, only one handle projecting through ENCLOSED SWITCH-COVER RAISED. the cover. If the switch is mounted directly on the machine, the operator is able to reach the handle quickly whenever necessary. When used on a lathe with a long bed, a horizontal lever can The switch is, of course, protected from mechanical injury by the case surrounding it, the case also eliminating all possibility of accidental contact with live wires. The cover is hinged and held firmly in place by a latch. When this latch is loosened, the cover may be thrown back, and free access obtained to the interior for inspection or repairs, as shown in the figure. This switch is made in three styles, two- and three-pole single-throw and four-pole double-throw. The switch shown in the illustration is of the four-pole double-throw type. The design of the others, however, is similar in principle. Canadian Tobacco SINCE its earliest history, tobacco has been generally regarded as almost a tropical product, the growing of it in for each acre. Connecticut being long considered as a sort of agricultural freak performance. It seems, however, that Canadian tobacco also will presently assume a position of importance in the commercial world. In the counties of Kent and Essex, in western Ontario, many farmers have abandoned sugar-beet raising to engage in the production of tobacco. Last year the crop was very profitable in this section, bringing the planters an average of $104 per acre. The average yield was 1,300 pounds to the acre, and the average price about 8 cents per pound. One farmer, on something less than six acres of land, raised a crop which sold for $1,006, or over $167 The Canadian Government is encouraging this industry in every way possible, and will shortly establish an experimental tobacco farm in Essex county. The President at Panama When President Roosevelt set foot on foreign soil at Colon, Isthmus of Panama, he broke another historic precedent. No other President ever left his native land during his term of office. Although his stay on the isthmus was so short, President Roosevelt made a careful first-hand investigation of the work under way, showing the same eager spirit and half-scornful disregard of personal comfort, which have distinguished him on so many other occasions. All along the canal zone he talked with the men, took a hand at running their machines, heard their complaints and suggestions, and inspired them with something of his own bubbling energy and enthusiasm. It is said to be his greatest ambition to go down into history as the President who built the Panama Canal. THE PRESIDENT (IN WHITE) ON REAR PLATFORM OF TRAIN IN CULEBRA CUT. |
