Fig. 3 is an enlarged view, in perspective, of a detached portion of the apparatus, as presently to be explained; and Fig. 4 is a longitudinal vertical sectionalview of a flue-boiler, and of my improved apparatus applied thereto.. In the ordinary .mode of utilizing soft or Jhitu'minous coal as a fuel, the waste by smoke land 'u'nconsumed gases is enormous. This is especially the case on railway-locomotives, ,iwliere the strength of the blast is such as to draw through and blow ont not only unconsumed gaseous products, but also solid matter in considerable quantities. As a means of avoiding such waste, or a considerable part of it, 1 employ a gas-producer, to convert the ,solid fuel into gaseous fuel, arrangesnch producer on the tender orfother {convenient part of the train, and conduct the lg ases andsmoke directly therefrom to the firebox, and. there ignite it in'connection with a' supply of oxygen. 1 have also devised an improved apparatus for heating and burning the 'fire-boxB' I arrange the apparatus presently to be described, or other suitable gas-burning and air-supplying'appa- ,r'atus suitable for burning the gases, smoke, given'ofl by the gas-producer. ,On thep u Haltwans, Pl'il TSBURG, P NNSYLV NIA,"Assienoa 'ro "artisans-HEN Yw rAgrfrsnson, AND JAMES inwmor sAMnrL cE,

This drum 6 has a long narrow slot or equivalent perforations, e, "Fig. 3,' fdr the introduction into the fire-box of the smoke, gases, &c., from the gas-producer in athin sheet or small jets at the desired point of ignition. The air necessary to supply oxygen at this point of ignition isintrodueed from without, and conducted along in 'or'back and forth inside of the fire-box by a pipe, .9, arranged with reference to being heated in like manner as already described with reference to the pipe 0, and so as to heat the ingoing air, which then passes into the cross-pipe or drum 1?, which latter is arranged in like manner as the drum 6, and has alike slit or series of perforations, t", as also shown in Fig. 3. These exit-passagesfor the heated gases and air are in such juxtapoand gases shall-quickly and readily commingle, and then, being ignited, will result in the the grate-bars; a thedainpers; a. ,the chargshown in all the figures,takesthe-gas, smoke,

then, entering the flue b, continues its work as a heating agent with a minimum percentage of loss. Fig. 4 is intended to show merely one waytofusing the apparatus described in connection with a flue-boiler. But the kind or class of boiler, or the kind or form of heatlng-chamber or fire-box, in or in connection with which the apparatus is used, or the purpose to which the heat, when generated, is to be applied, is not a material element in this employed.' Instead-of air, any oxygen-bear ing gas or vapor-may be employed in "In:

manner, and for the purposes of this case I include the latterinthe term used. Also, with stationary heaters, where natural gas is available, the producer may be dispensed with, and the natural gas be conducted directly into the pipes c and drum e. with the operation and-result above described.

I claim herein asmy in'vention 1. The pipes c s and sli'tted or perforated cross-tubes or drums-e i, arranged in the firespace of a heating apparatus, with the drums opposite the exit-flue, and the pipes in the line of draft between the drums and exit-flue, substa'ntially as set forth. 7

2. A gas-producer, a gas-heater, and burner apparatus connected therewith, and an air heating and supply apparatus for perfecting the combustion of the gas, arranged on and combined with a locomotive and tender, substantially as set forth.

In testimony whereof I have hereunto set my hand.
