UNITED STATES; PATENT OFFICE.

HERMANN LEMP, OF LYNN, MASSACHUSETTS, ASSIGNOR TO GENERAL ELECTRIC COMPANY, I

or NEW YORK- FLUE CONSTRUCTION r03 VEHICLES.

To all whom it may concern.

Be it known that I, HERMANN LEMP, a citizen of the United States, residing at Lynn, county of Essex, Slate of Massachusetts, have invented certain new and 5 useful Improvements in FlueConstruction for Vehicles, of which the followingisaspecification. I

I have discovered inconnection with Vaporizers fob vehicles, particularly where liquid fuel is employed, that an up or natural draft when properly combined There is, however, one objection to such an arrange ment. Assuming that there is a relatively high wind, and the vehicle has been in operation long enough to' have all of the parts hot. If before the-fire can be materially checked the vehicle is stopped or caused to move slowly, the wind will blow into the'down flue in such a manner that the flames will be. driven or spread outwardly, frequently resulting in setting lire to the woodwork ot' the carriage. Many accidents to carriages l have occurred which have beenicaused in this manner.

In event otthe use of gasolene or other highly inflammable fuel,' it sometimes happens that the operator ismo re or less burned beibre he or she can jump out of the vehicle. I overcome the objection above pointed outby utilizing a cross or transverse flue which is so connected and disposed with respect to the main line that wind cannot blow directly down the latter. A further advantage of my improved construction lies in the fact that the waste products of ((-mlb'UStlOIl are conveyed to the sides of the. vehicle, and there allowed to eseape, tlmsreducing. the liability of damagingthe canopy of the vehicle in case it is down. This also tends to prevent the. gases from annoying the occupants of the vehicle. i

I in the" accompanying drawings which illustrate an embodiment of my inventionyl igurel, is afperspective view of a vehicle body showing'the vaporizer in place. Fig. 2, is a perspective view oi a part of the. vehicle body showing the cover for the inclosing case raised to permit inspection of the boiler. Fig. 3, is a perspective view 01" the boiler, and Fig. 4 is a vertical section thereof with the cross-flue in position to receivethe productions of combustion. l

I 1, represents the vehicle body which is extended rearwardly as at 2, to form an inclosing box or casing for the steam generator 3. Thecasiug 2, is provided with ahinged cover 4-, which may be raised or lowered at will to inspect the boiler.

Specification of Letters Patent. Applicationfiied July 27, 1901.

For convenience of illustration, as representing one type of boiler and burner I have shown a flash boiler anda kerosene burner, but my invention is not to be construed as being limited to the use of any particular kind of boiler-or burner or combination thereof. The boiler proper consists of a pipe 5, .which is bent into any convenient shape, and is inclosed by a'suitable v Patented July 9, 1907'. Serial No. 69,904. I

easing 6. Between the layers or grids of pipe spaces are formed which act as flues for the fire gases. Below the boiler tubes, which are supportedin anysuitable manner, is located a cylindrical body of fire-brick 7. This forms a part of the fire-chamber and surrounds the burner, which burner, in. the present instance, consists of a nozzle 8, baffling plate 9, and a vaporizer 10. The necessary air to support combustion enters by means of the holes 11, which are located near the cor ners of the casing 6. The air in passing downward, around the cylindrical-fire-brick lining 7; becomes more or less heated thereby adding to the economy of the system. The bottom of the boiler casing is closed by the plate 12, and is provided With a small door 13-, through whichan igniter may be inserted or the burner inspected. Extending across the top of the .boiler casing is a plate or-partition 14-; this'partition is provided with an opening 15, through which the fire gases, indicated by the arrows, are free to pass. .In the upper end of thecasing between the partition and the top is formed a chamber 16, which chamber isprovided at the rear with a short upwardly extending flue .17, and.

this in turn engages with the'flue-18, carried by'the cover 4, of the vehicle body. The chamber also opens into the down flueas will appear hereinafter. 1 may dispense with the partition 14 and permit the ire gases I to pass directly out the up and down flues the action oi the cross flue being the same in both cases. In using the word chamber I do not mean to restrict myself to the structure-shown wherein a portion of the casing is actually divided off, but use it in a broader sense as meaning a space wherein the lire gases mingle more or less freely beforepassing through the flues.

The flue 18, may be secured to the cover in any suitable manner, and is provided with an open ended cross l .or transverse flue 20, consisting of twosubstantially horizontal divergent branches, each branch in the present instance is shown as being semi-circular in outline,

but any other form may be substituted if desired. The flue 20 extends transversely of the vehicle body and terminates at'or near the side walls thereof. The fine 17, is rectangular-in outline as will readily be seen in Fig. 3, and the flue 18, is of corresponding shape and just enough larger so that the cover 4, may. easily be I raised, as is illustrated in Fig.2. The cross flue20, is 1-00 made somewhat longer than the flues 1 7 and 18 so that no opportunity will be afforded for a gust of wind to blow down through the flues 18 and 17 and flues between the boiler tubes into the fire chamber and cause the flames to be forced outward through the air admitting openings 11, or through anypther opening or openings in the boiler casing which are made intentionally or otherwise. By making the cross flue 20, somewhat longerthan the flue 18, the waste products of combus: tion are carried to the'sidespf the vehicle, so'that they I10 will not annoy the occupants either when the vehicle is standing still or moving slowly. It also prevents the The chamber 16, formed the upper end of the boiler easing besides opening upward is provided with an opening 21, which commuhicates with a vertically extending flue 22, that creates the down or forced draft when the vehicle is in operation. This flue'is preferably made of sheet metal and is secured to the side of the boiler casing G, as is indicated in Fig. 3. The fine is closed at its upper end 23 but is open at the lower end, as is indicated in Fig, 4. Passing through the chamber 16, is the exhaust pipe 24, from the engine, which is turned downwardly, as is ind'icatcd'indotted lines, at the point where it enters the flue 22. iis soon as the vehicle is started into operation, and exhaust steam passes through the exhaust pipe and'into the down fine, the

' draft is materially increased and the waste products of combusti m, instead of passing out through the vertical -fiues17 and 18, and through the cross fine '20, pass out through the downwardly extendirig fine 22 and are pro jected toward the rdadbed. The length oi the line 22, and also that of the cross fine 20, can be yaried to suit the vehicle to which the apparatus is applied. By I mountinglthe cross flue 20, on the cover 4, of the vehicle-body, a very convenient arrangement is provided whereby the boiler and the other parts of the vehiclemaybe inspected. It will be seen that the parts are so arranged that the wind cannot blow directly down through the vertical fines-18 and 17, into the chamber 16, thence to' the fire-box, neithercan any waste prodnets of combustion pass throughthe fines and strike the vehicle canopy, in-case such a canopy is used, for they wiil be deflected across to theside oi the vehicle.
