PROPERTY AND LOSS OF LIFE PALMBR'S PATKNT HIGH AND LOW WATER ALARM GAUGE. ^N presenting this circular to the public, I wish to say a word by way of explanation, I having been CJ an engineer for over eighteen years, both by practice and theory, and having had the charge of a ^ large number of steam boilers and engines, both stationary and marine, and know the great necessity and want of having an automatic alarm attached to every steam boiler. It is a well-known fact that often the care of steam boilers are entrusted to men of intemperate habits and incompetency, which endangers human life and property. By this patent the whistle will blow and continue doing so, and every one in the factory will know that something is wrong, and it can be rectified in time to save accident and damage. In offering this alarm gauge to the public, I feel confident, after long study and experience, that it is the very best gauge in existence. It has no equal. Its principles are entirely new and its workings are based on the very best and latest scientific principles. IT IS THE SUREST, SIMPLEST AND CHEAPEST GAUGE EVER MANUFACTURED, CRNNOT CORRODE OR OET OUT OF ORDER. IT HMO NO RIURL. — ITS ADVANTAGES ARE First — By not letting the water get low in the boiler, thereby saving it from getting burnt or exploded. Secondly — By not letting the water in the boiler get too high, reducing the steam space, and causing wet steam ; also water drafting over into the engine, causing large breakdowns and destroying property, as high water has so frequently done. Third — By keeping the water nearly at one level in the boiler at all times, thus saving a large amount of fuel and ensuring good dry oteam, which, coupled with the large saving in fuel, will pay for itself in less than a month. Nobody shoukl endanger their property and lives where so sure a pre- I M veniaiive can ce procurea tor so trming an amount. Yours respectfully. r T- C- i=>..A-i-ivd:E]ie, r' ' •• I ' ' ' ' ' M.E. 1 k- ': ' . A... c • ' -../^.,.. 1* ■-J '■( DKSCRIPTION^ I •• V ^1 't Consisting of hardened floats and the arrangement of levers, valves and fulcrums are such that it is impossible for it under any circumstance to bind or stick, corrode or get out of order, the balls being made of copper ; levers, valves and all external connections are made of the best steam metal. It is pronounced by scientists and practical men, and by those who best understand alarms, to be the best alarm gauge in existence, its workings being absolutely perfect. It is so arranged, that should the water supply be shut ofT, the pump or injector get out of order, the boiler spring a leak, or should the water from any other cause get down to the lower gauge co:;k, or down to whatever point the valve is set at, the steam whistle for low water will blow an alarm and con- tinue to blow until the water is put in the boiler. It will indicate at all times the exact height of solid water in the boiier, regardless of foam ; so with this protection the boiler can never be injured or ex- ploded on account of low water. Then, when the water raises in the boiler above the proper level or height desired, the high water alarm will begin to blow and will con- tinue to blow until the water recedes or the fireman opens his blow-off cock. This also •feminds him that he must blow off his boilers, thus pre- venting sediment and incrust- ation to form in the bottom of the boiler. It also prevents the water from raising too high, causing wet steam and often great damage to the engines and machinery. As will be seen by the cuts, the floats are at one end and the fulcrum is at the other, and the valves being close to the fulcrum gives the float suffi- cient leverage, that when the water bears against it, it opens the valve and blows. The alarm whistles under i,ooo lbs. pressure, which is more than any steam boiler will stand. The floats are hardened by an entirely new process, which leaves them perfectly round and smooth, and they are tested outside and inside by a pressure of 300 lbs. to the square inch. They are then plated with nickel, so that the steam cannot oxidize the spelter. NO FLOAT OF THIS PATENT EVER HAS OR EVER CAN COLLAPSE OR FAIL. It is not necessary to shut down the boiler to examine the internal parts of the gauge. All you have to do is shut off the valve between that and the boiler. The height of the water in the boiler is at all times indicated in the glass, and the water cannot leave the glass without the alarm^being sounded. The glass gauge and alarm are separate, and* each complete in itself. If the glass should get broken from any cause, shut off the valve, and still you have a perfect alarm gauge. No such gauge has ever been offered to the public at any price or at any time. •V /* ^ r( '^/ EHGHTHBES LIKE THEM, Because they give timely [ warning of approaching clanger. The whistle com- mences gently, and if dis- regarded, will soon alarm the whole establishment. It also, in many cases, saves his reputation. PEOPRIETORS LIKE THEM, Because they save their boilers from injury, and their engines from expen- sive breakdowns, and in- sure them good dry steam by keeping the water at the proper level in the boiler, also saving fuel, therefore making their boilers last longer. With this protector, the flues, crown sheets or sides of the boiler can never be burned or injured for want of water. Neither can the boiler be exploded. Every guage is provided with a test blow-off valve the full size of the pipe, so it can be tested as often as desired. It cannot be tampered with. It is easy to attach to any boiler. EVERY GAUGE IS WARRANTED FOR FIVE YEARS. For prices and full particulars, apply to THE ONTARIO BOILER PROTECTIVE OO.'S OFFICE No. 230 James Street North, A. VINCENT, Manager. HAMILTON.
