AUTOMATIC INJECTOR.

For Boilers of Stationary, Portable or Traction Engines, Steamboats, Etc,

The Lunkenheimer Automatic Injector is a simple, durable and efficient boiler. feeder, not liable to get out of order, and is fully guaranteed in every particular It is warranted to give in actual service as good, if not better, results than are herein claimed for it.

We do not hold that these results are phenomenal as compared with the claims Of others, but we do confidently assert that our machines will, in actual service, substantiate all our statements. The Lunkenheimer Automatic Injector will satisfy the most exacting engineer, as it will be found in practice to be reliably automatic under all ordinary conditions, to have full capacity under higher steam pressures than others, to be unaffected to any extent by varying steam pressures, and the maximum amount of water delivered is capable of being graded over 50 per cent.

CAPACITY.-The table of capacities has been taken from actual working tests and is not "estimated." Allowances have been made for contingencies, and if a new Lunkenheimer Injector is properly attached to a boiler and does not fulfill our guarantee, the user is at liberty to return it to us at our expense. We state plainly herein that all tests are made on a 5-feet lift, with steam pressure at 75, 85 and 95 pounds and feed water at 75 degrees F. We believe that these conditions are more severe than those under which other manufacturers test machines of this kind.

DURABILITY.-The Lunkenheimer Automatic Injector is very durable because all parts are of good proportions. The machine is made entirely of brass and the tubes of a special hard bronze composition made expressly for the purpose. Owing to the construction of the tubes, the arrangement of the spill holes will not diminish the durability of the machine, as is the case with other injectors of the automatic type. Another improved feature is, that the interior areas of the tubes are smaller than others for capacities claimed to be equal; hence the tubes of our injector will not wear out of size as rapidly as others. Every part about the injector is interchangeable, and new parts can be supplied to replace worn ones at slight expense.

EFFICIENCY.-An impartial test will clearly show that the Lunkenheimer Injector excels in this particular. The range of work covered is very wide, as shown in table herein, and it can be graded over 50 per cent under all ordinary conditions. Our Injector will deliver more water per pound of steam than any other, which means a saving in fuel. While the capacity of all injectors is diminished by long lifts and hot feed water, the capacity of the Lunkenheimer is less affected by such causes than any other makes.

AUTOMATIC.-The Lunkenheimer Injector is absolutely automatic at all times, and can be relied upon to restart instantly after a temporary interruption of either the Steam or water supply, DESIGN.-The exterior appearance of the machine is very handsome, as the brass body is wire brushed and the trimmings bright finished. All unions have ground joints and will come tight easily. The Lunkenheimer machine again differs from other injectors of the automatic type, inasmuch as the internal areas of the body are made larger than usual, which accounts for, in a large degree, the excellent working of the machine. The general construction of the body is very heavy and rigid, so that same cannot be sprung by the strain put upon it by the connecting pipes.
