ROAD-OILER.

Specification of Letters Patent.

Application filed May 13,

1910. Serial No. 561,062.

To all whom it may concern."

Be it known that I, WILLIAM H. GAILOR,

a citizen of the United States, residing at Saratoga Springs, in the county of Saratogaand State of New York, have invented an Improvement in Road-Oilers, of which the following is a specification.

My invention relates to improvements employed in connection with the road oiling devices shown and described in my application for Letters Patent of the United States filed July 24, 1909, Serial No. 509,458. In this and other devices employed by me as road oilers, a steam boiler and fire thereunder have been employed and the steam generated was utilized to heat the oil or other material employed to effectits delivery on the surface of the road. In this device much valuable heat and energy were lost and the apparatus could not be run with a maximum economy or the oil delivered upon the road carrying sufficient units of heat.

In my present invention the steam boiler with its fire and the use of steam therefrom for heating the oil or other material are dispensed with and a fire is employed under the tank holding oil or other suitable mate rial, and this fire heats the oil or other suitable material employed, and the hot gases or products of combustion of said fire are utilized and directed through a heating chamber containing a reservoir, a distributer reservoir'and connecting pipes for the oil or other material to bedelivered uponthe road so that these smaller bodies containing the material moving therein are additionally heated by the hot products of combustion coming from the combustion chamber and passing away by one or more stacks or chimneys rising from the heating chamber.

In the'drawing, Figure 1 is an elevation and partial section representing the essential features of my improvement; the section being taken through the case of the heating chamber and also through the case of the distributer reservoir. Fig. 2 is an elevation and vertical longitudinal section at about the dotted linew, w, of Fig. 1, and Fig. 3 is an elevation and vertical longitudinal section similar to the section Fig. 2 but illustrating another form of my apparatus.

Similar letters of reference in the several figures indicate similar parts.

In these figures of the drawing, the oil tank or tank holding other suitable material to be heated and delivered upon thgsurfa'ce of a road is represented at 10, and at 11 there is a long pipe reservoir and between the tank and the reservoir a pipe 12 and a controlling yalve 13. therein. The distributer reservoir 1s represented at 14 and connecting the same and the reservoir 11 there are series of pipes 15 with valves 16 therein.

The distributer reservoir 14 is preferably formed of plate metal with one side fixed and one side adjustable so that there is a delivery slot 17 between said two parts which is regulated by one or more adjusting bolts 18. So far as just described, these parts agree substantially with similar parts shown and described in my aforesaid application and which are employed for bringmg .the oil or other suitable material from a common tank 10 to the reservoir 11 and therefrom to the distributer reservoir 14 and delivering the same upon the surface of the the same.

The special features of my present invention comprisea casing beneath and along the tank 10 forming a fire-box or combustion chamber a, which may be constructed in any desired or suitable manner and at one plate (1 The caslng comprisingsides 2, 4, a bottom 3, a top 5 and ends 6 of plate metal is employed and surrounds and entirely incloses the reservoir 11, pipe 12, valve 13, distributer reservoir 14, series of pipes 15 and their valves 16, with the handles of "the valves 13 and 16, extending through the top operation. The casing of these parts comprises a heating chamber b connecting with the combustion chamber a and rising from I have in the drawing shown two stacks, one at each side of the stem and handle of the valve 13 which permit of the operation of the valve when in the position illustrated. I have shown Within this heating chamber a swinging bathe-plate d upon a'shaft 0Z both of which preferably run the entire length of the heating chamber 5; there being a handle (P at oneend upon the shaft 03 outside the heating chamber for actuating the swinging battle-plate. This baffle-plate comprises parts at an. angle to one another with the shaft 03 located at the intersection.

In Fig. 2 I have shown the baffle-plate d in .its two extreme positions. In the full line position one edge comes up against the end is preferably provided with a bafllethis heating chamber is one or more stacks c.

Patented Sept. 10, 1912 road, oiling'the road or otherwise treating 5 and side 4 of the casin for their proper under side of the tank 10 and the other edge rests upon the reservoir 11. In the dotted position the one edge rests upon the upper surface of the baffle-plate a and the other edge comes up against the under surface of the pipe 12. r

The casing constituting the fire-box a. may be of any desired construction for holding a fire of Wood or coals for heating the tank 10 and the contents thereof; the portion shown in Fig. 2 being only the combustion chamber away from the fire portion.

All the hot gases and products of com-- bustion must pass beneath the tank 10 and 5 the upper edge of thebatiie-platea ,throi1gli the heating chamber 6 and away by the stack. In the full line position of the swinging battle-plate d these products of combustion are by said baflie-plate diverted down into the lower port-ion of the heating chamber 1) where they entirely surround the reservoir 11, distributer reservoir 14, pipes 15 and valves 16 and must pass beneath the battle-plate d before rising into the upper part of the heating chamber]; around the pipe. 12 and valve 13 before escaping by the stack or stacks 0. Thus the devices through which the oil or other materials pass from the tank to be distributed upon the road are not only thoroughly heated,

but brought to a high heat and the contents brought to a higher heat than would be possible by the use of steam as I have heretofore employed it. The full line position of this swmging baffle-plate is that employed in the operation of the device, while the dotted line position is that usually employed in starting the fire where one edge of the swinging'bafiie-platerests upon top 40 of the bafiie-plate a and the other edge comes beneath the pipe 12, giving ready access to the stacks o'r chimneys. In fact I prefer to put the handle d upon the shaft 01 of the swinging baffle-plate in such a position that it will assist in keeping the baflieplate in the full line position Fig.2, for use.

In the device of my invention, the hot oil or other material is evenly distributed upon the ground or surface of the road closely adjacent thereto. The bottomof the casing or heating chamber also comes close to the ground and serves to heat the surface of the earth somewhat before the oil or other hot material is delivered thereon, and in i this manner both the heating of the material to be delivered and the heating of the surface to receive the material being delivered are facilitated.

0 Referring particularly to Fig. 3, which represents a second form of my apparatus, similar parts having similar letters and numerals of reference as in the other figures, except that in this figure the casing below and at the rear of the oil tank 10 is so arranged and constructed as to provide an uptake chamber e, with an opening at uptake still at the rear of the uptake 6 designated by the reference letter 1 in which below the plane of the valve or damper 7 is placed a valve or damper 8, while a baffleplate of fixed construction is indicated at d, and in the operation of this structure the heated gases and products of combustion from the fire-box or combustion chamber a beneath the oil tank 10 ass over the baffle plate a beneath the xed baffle-plate d circulating through the heating chamber and around the various devices therein conveying oil or other suitable material from the tank 10 up the passage-way f, with the valve or damper 8 in the upright open position shown in Fig. 3 and away by the stack 0. Thus the products of combustion and hot gases are utilized to thoroughly heat the various conveying devices in the heating chamber 6.

In starting up the fire under the tank 10 it is preferable to close ofl the valve or damper 8, that is, by turning the same into a horizontal position and by opening the valve or damper 7; that is, by turning the same into a horizontal posit-ion, in which case the passage-way being closed off the products of combustion pass up the passageway e through the throat, past the damper or valve 7 and away by the stack 0.

When the fire gets going and it is desired to heat up the devices in the heating chamber b, the damper or valve 7 is turned into a vertical position as shown in Fig. 3, to close off the connecting throat between the passage-way e and the stack; thus compelling. all the products of combustion and hot gases to pass through the heating chamber 6 around the devices contained therein and up the passage-way f to the stackc.
