MOTOR-VEHICLE.
SPECIFICATION forming part of Letters Patent No. 766,830, dated August 9, 1904.
Application filed December 30, 1902. Serial No. 187,144. (No model.)
-have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specification.
My invention relates to apparatus for controlling drafts through fines and regulating the same, and is especially adapted for use on motor-vehicles of the type adapted to be operated by steam.
The objects of my invention are to properly dispose of the products of combustion, to induce the desired and necessary draft at all times, to prevent back drafts from wind, &c., to enable the operator to force the draft when firing up or at other times when the engine is not running, and, finally, to obviate choking the combustion-chamber with an excess of combustible gas under severe road conditions.
It has been the common practice in steamvehicles to utilize the exhaust of the engine to turn the products of combustion downward to .the road and to sharpen the draft. It is well known that this sharpening of the draft increases the steaming e'fliciency, In apparatus where a hydrocarbon-burner is employed this sharpened draft permits the use of much more combustible gas than can properly be disposed of otherwise, and consequently from that cause, if from no other, increases the steaming capacity. It is also common practice to allow both upward and downward escape of the products of combustion, in which case the products of combustion escape through an upward outlet when firing up, as also when the engine is not running, but are forced downward through a flue-outlet by the impact or exhaust action of a downwardlyturned exhaust from the engines delivered in the clown-flue when the engine is propelling the vehicle. As the exhaust-fines are ordi narily constructed the force of the draft through the boiler is very much weakened by flue entering through the upper opening, already deseribed. Wind-currentspart1cular1y affect the upper opening in the exhaust-flue, interfering seriously with the draft. Consequen tly a flow of combustible gas to the burner that can be advantageously handled while the engine is running becomes immediately excessive upon the cessation of the exhaust from the engine, causing the burner to smoke and frequently the excess of combustible gas to come out beneath the burner, with the consequent danger of confiagration. My invention overcomes all these difiiculties and may be carried into effect by the construction shown in the accompanying drawings, in which- Figure'l .is a longitudinal section through a motor-vehicle with a portion of the boiler broken away, showing the relative position of the parts. Fig. 2is a plan view. Fig. 3 is a rear elevation of the upper portion of the exhaust-flue.
Like numerals indicate corresponding parts.
In the drawings, 10 indicates the boiler, 11 the engine, and 12-horizontal flue leading from the top of the boiler and discharging into a vertical fine 13. Arranged over the top of the vertical flue 13 is a horizontal line 1 1, to which are connected the vertical end portions 15. These vertical end portions are open at the top and bottom. Arranged within the horizontal flue 14 are the dampers 16.
' 17 ind ieates themain steam-pipefrom boiler to valve-chest of engine; 18, throttle-valve in main steam-pipe; 1 9, exhaust-pipe leading from engine and discharging in a downward direction into the vertical fine 13; 20,.pipe leading from the top of boiler and discharging as a jet in the vertical flue 13; 21, valve in pipe 20; 22, automatic regulator-valve in pipe 20. This valve is preferably of what is known as the diaphragm type and is connected at the left of the diaphragm that is, in front of the diaphragm-through pipe 23 to main steam-pipe 17. Arranged around the stem 24L of the regulator-valve is a spring 25, which normally tends to maintain the valve in an open position. the access of a1r-currents to the downward The operation of this invention will be readily understood. On firing up before steam-pressure is obtained the dampers 16 are left open to allow the products of combustion to escape upward through the vertical flues 15. The vertical fiues 15 serve to prevent wind currents from entering the flues 14 and 13, and thereby reverse the normal upward draft. After some steam-pressure has been obtained the valve 21 in the pipe 20 is opened, which allowslive steam to flow through the pipe 20 and be delivered in a downward direction in the vertical flue 13, thus creating a downdraft in the flue 13. The dampers 16 may then be closed, which prevents air from entering through the flues 15 14, and thereby destroying the usual effect upon the boiler and the burner of the forced downward draft, created as above described. When the vehicle is being propelled, the exhaust-steam issuing from the pipe 19 and discharglng in a downward direction in flue 13 induces a strong draft in the down-flue. hen steam is admitted to the engine, steam-pressure is also communicated, through the pipe 23, to the front of the regulator-diaphragm, which by moving the diaphragm inward corresponding-1y moves the "valvestem against its seat in the pipe 20', thus closing the direct live-steam passage from the boiler to the jet in the flue 13 through the pipe 20. WVhen the steam-pressure in the pipe 23 is cut off, as it will be by closing the throttle 18 of the engine, the spring 25 moves the valve-stem forward away fronrits seat, thereby opening pipe 20-and allowing steam to pass from the boiler and be discharged in the vertical flue 13 in a downward direction, thus automatically inducing a draft in the down-flue when the engine is not working and cutting off the live steam from the jet on pipe 20 to vertical flue 13 when the engine is working.
If it is desired to leave the vehicle standing, with the fire extinguished, the valve 21 in the pipe 20 is closed, as also the dampers 16, with the effect that the upward flow of air through the boiler-flues is out off and the steam-pressure thus maintained for a longer period than if free circulation of air through the boiler is permitted.
I wish it understood that I do not limit myself to the precise construction described, as many modifications may be arranged without departing from the spirit and scope of my invention. For instance, the flues 13 14 15 could be differently arranged, the deliveryjets from the pipes 19 2O differently placed as regards the flues 13 14: 15, the automatic 'regulator could be connected to be actuated by pressure in the exhaust-pipe beyond the engine, the automatic regulator could be arranged to be actuated by direct pressure from the boiler, as may be preferable if using solid fuel, the parts may be so arranged as to maintain a suflicient draft at all times in a downward direction without closing the dampers, and, further, the live-steam pipe may have another automatic valve introduced in it adapted to be operated by direct boiler-pressure to cut off the live-steam jet when sufficient boilerprcssure has been obtained.
Having thus described my invention, I claim- 1.
