36 fe ke lel UNE FLINN STEAM TRAP. Richard J. Flinn, West Roxbury, Mass., in a little folder describing the Flinn steam trap says that the first service of a steam trap is to re- | move condensation without waste of steam, The Flinn trap opens freely for water but closes tight when steam comes. He says also that the temper- ature of the water en- tering the trap should have nothing to do with its operation and adds that the Flinn trap handles water at any temperature: Without readjustment and while handling water at any tempera- ture a trap should work equally well at every pressure from that of the atmos- phere up to its maxi- mum. The Flinn trap responds instantly un- der every condition. To prevent wire- Ye CQt set GG wo | NSS drawing (which cuts YY y Y valve seats) a valve should instantly move to its wide-open cially when handling small quantities of water. of the Flinn trap is either wide open or tight shut. In answer to the question as to what works the Flinn trap he replies that it is the weight of the water that enters the inlet pipe of the trap. 'The first water that comes to the Flinn trap water seals it. The very next ounce of water opens the valve. The valve stays wide open if the water keeps on coming. The valve closes instantly after discharg- ing. to its' water 'seal level. The operation is just the same, as in- stantaneous and as reliable with pres- sures of I lb., 50 lb., 100 lb. or 150 lb. The temperature of the water may be 300 degrees--these traps handle it at any temperature, hot or cold, with- out letting even a thimbleful of steam escape. <lhe operation of the trap may be described by reference to the accompanying diagram. Briefly, the column of water X, acting on the diaphragm closes the valve. The water entering pipe E together with the action of the spring equalizes column X, and opens the valve. That's all there is to it. De- scribing the action in further detail-- A the water of condensation enters at in Meas ce chamber V. poe Xiand W receiving chamber C up to the level of the top of pipe E. This column of water, acting on the under side of the diaphragm D forces the valve to its seat against the counter pressure of the spring S. Any additional position, espe- The valve Rob: V2 ke Ww water that enters the trap overflows through pipe E, filling chamber F and pipe E to a point about midway of its height, where the effect of the column of water in pipe X is bal- anced. The pressure on each side of the diaphragm is then equal--the shorter column in pipe E, aided by the spring, bal- ancing the pressure of the longer column in pipe X. Any further increase in the height of the water in pipe E causes a depression of the valve V, which allows water to escape until the column has fallen to a level a little below the middle of pipe E when this valve closes again. This action is repeated at intervals according to the quantity of water entering the trap. So long as the water keeps coming in sufficiently large quantities the valve remains wide open. TONNAGE OF THE NATIONS. Lloyd's Reporter of British and Foreign Shipping have just published their register books for 1904-5, which, it is needless to say, are indispensable in all shipping and insurance offices. The features of the volumes are well-known. Below are given the figures of the tonnage owned by the different nations, but it should be stated that in so far as American tonnage is concerned Lloyd's figures do not include the vessels of the great lakes which is full half the tonnage enrolled under the American flag. The total tonnage has increased during the year from 33,643,131 tons to 34,780,189 tons, and British ton- nage from 16,006,374 tons to 16,580,845 tons: 1903. 1904.
