Application illed'lay 14, 1914. Serial N o. 838,445.

To all 'ui/10111 it 11u/y (fonce/'1a.'

Be it known that I. HARVEY W. BELL, a citizen of the United States of America, and

a resident of Yonkers, lVestchester county,.

and State of New York, have invented certain new and u'seful Improvements in Self- Propelled Road-Builders Vehicles, of which the following is a specification, reference being had to the accompanying drawings, forming apart thereof.

My invention relates to a self-propelled road builders vehicle', and its object is to provide a self-contained outfit in which material may be heated and transported.

More specifically its object is to provide on 'a vehicle a steam propelling engine and a receptacle withl a heater pipe coil and a steam generating plant for providing steam for the engine and either directly orindirectly to the heater pipe coil.

Another object is to provide a closed receptacle with heater pipe. coils and a steam actuated air compressor for supplying pressure to the receptacle.

These and other objects of the invention will appear in the following specifica-tion, in which I will describe my invention, the novel features of which Will be set forth in the appended claim.

Referring to the drawings: Figure 1 is a side elevation of an apparatus which embodies my invention. `In this figure a part of the tank receptacle is broken away to show more clearly the location of the heater pipe coil. Fig. 2 is a transverse section of a part of the apparatus shown in Fig. 1, the section being taken on the line 2--2 of the latter figure.

Like characters of reference designate corresponding parts in all the figures.

10 designates a Wheeled vehicle upon which is a steam generator 11, preferably in the form of an oil burner boiler. A steam engine 12 is arranged and connected to propel the vehicle.

13 is a cylindrical tank receptacle over and partly surrounding which is a Water tank 14.

15 is a steam actuated air compressor.

A Water pipe 16 leads from the Water tank to the boiler through a suitable injector or pump which is not shown.

17 is the steam pipe from theboiler. A branch pipe 18, controlled by a. valve 19, provides means for connecting a hose or other pipe with the steam supply to lead it to a tank car or other extraneous apparatus.

The steam supply pipe 17 is connected by a pipe 20, controlled by a. valve 21 With the engine, and the engines exhaust is connected by a pipe 22 with a heater pipe coil 23 within the receptacle, through which, 'the exhaust steam passes and from which it goes into the atmosphere through an outlet 24. A valve-controlled by-pass 25 pro-vides means for leading live steam from the boiler to the heater pipe coil. The steam supply pipe is .connected with the steam inlet of the air compressor .,-by a valve controlled pipe 26 and the steam outlet from the compressor is connected by pipe 27 With the pipe 22 which leads to the heater pipe coil.

28 isan air pipe leading from. the compressor to the upper part of the tank receptacle 13.

I Will now describe the operation of the apparatus which has been described. This apparatus is especially designed for road builders use but of course my intention is that it be put to any other use 'to .Which it is adapted. It is used to transport hot bituminous or other materials which are in molten condition when heated. Such materials are usually delivered in tank cars which are provided with heater pipe coils. My apparatus may be run alongside of such a car and steam supplied from its boiler to the heater pipe coil of the car through the connection 18. l/Vhen the material has been melted it may be transferred to the tank receptacle 13. The vehicle propelled by the engine 12 may be then moved to the desired place or places, the exhaust steam from the engine being utilized to keep the material in molten or heated condition. If the' vehicle has been at rest and a quicker heating effect is desired than is obtainable from thel exhaust steam from the engine, live steam may be introduced into the heater pipe coil through the by-pass 25. The by-pass may be used also during periods of rest of the engine. The position of the Water tank 14 is a convenient one and is such that the Water in it absorbs a part of the heat of the tank receptacle 13. j

It is often required that the material in the tank receptacle be discharged therefrom by pressure. The tank is therefore so made that it may be closed. Obviously a steam pipe may be led from the boiler into the tank for the purpose of getting pressure therein, but as the moisture of the steam has a deleterious effect upon some of the materials which are carried 1n such an apparatus as this, I prefer to provide the steam thereon, a heater pipe coil Within the tank receptacle, a water tank over and partly surroundlng sald receptacle, a steam-actuated compressor for produclng pressure Within said receptacle, a steam engine a'rranged to propel the vehicle, a steam connectlon 'from the boiler to the engine, a

steam connection from the engine to thev heater pipe coil, a by-pass connection from the boiler to the heater ipe coil, a steam connection from the boller to the compressor, a steam connection' from the compressor to the heater pipe coil, and a water connection between the water tank and the boiler.

In testimony whereof, -I have hereunto set my hand this 11 day of May, 1914, in the presenceo two subscribing wltnesses.

HARVEY W. BELL.
