UNITED STATES PATENT OFFICE:

MATTHEW VAN ALSTYNE, OF ALBANY, NEW YORK.

PORTABLE APPARATUS FOR HEATING A BINDER FOR ROAD CONSTRUCTION.

To all whom it may concern Be it known that I, MATTHEW VAN AL- STYNE, a citizen of the United States of America, residing at No. 4: Chestnut street, in the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Portable Apparatus for Heating a Binder for Road Construction, of which the following is a specification.

My invention relates to portable apparatus for heating a binder for road construc tion, and the objects of my invention are to' provide a portable apparatus for retaining tar or other substance to be heated or melted, provided with a means for heating and melting the contents thereof, with a means for the substitution of parts when worn or injured; together with such elements and combinations as are hereinafter more particularly set forth and claimed. I accomplish these objects by means of the mechanism illustrated in the accompanying drawing, in which:

Figure 1 is a cross section along the line XX on Fig. 2. Fig. 2 is a longitudinal section along the line ZZ on Fig. 1. Fig. 3 is a detail perspective view, with parts broken away, showing the tank and end plate. Fig. a is a perspective View, with parts broken away, of the enveloping plate with angle bar attachment. Fig. 5 is a section, with parts broken away, showing the manner of attaching the tank to the enveloping plate, with an intervening asbestos strip.

Similar letters refer to similar parts throughout the several views.

In road making it is necessary very often to heat and place in a viscous or semi-liquid condition on the road a suitable substance, such as tar and like substances, requiring a furnace and a kettle of some kind. For the sake of economy and convenience, it is advisable that the kettle or tank should be as large as can conveniently be handled and that the fire grate should be ample in size to make a large bed or coals obtainable. As the road progresses it is necessary to move the apparatus and therefore it should be portable. As it is necessarily exposed to the weather it should be so constructed as not to be injuriously affected thereby, and it should be so arranged that in case of the breaking down of one of its parts another could be substituted without long delay.

Serial No. 621,748.

I have provided a portable apparatus which conforms to the requirements above referred to and which has other very important features, which are readily appreciated by those familiar with road making machinery.

On the wheels, A, A, which are mounted in any suitable manner, I place a metallic housing, B, which is preferably constructed of boiler iron at the sides and bottom and open at the top, the side plates having secured to them by suitable rivets or in any practical manner the angle bars, C, C. At one end of the housing, B, I arrange the smoke chamber, E, communicating with a smoke stack, D, and near the opposite end of the housing, B, I arrange a depressed fire chamber, F, in which near the bottom is placed a grate, G, and at the end thereof a Fitting into the housing, B, is-the tank, J, made of boiler iron or other suitable material, curved and having at its edges a flange, K, adapted to rest upon the angle bars, C, C, of the housing, B, to which it is secured by suitable bolts, L, passing through the openings in the flange and angle bars. I

Each end of the tank, J, is a rectangular plate, M, which extends from the top of the tank to the extreme depth thereof, as shown in Figs. 1 and 3. WVithin the depressed fire chamber, F, I place preferably the perforated side walls, f, f, spaced a short distance from the housing, B, allowing for an air jacket between the walls, 7, and B, and to take up the expansion and contraction.

The ends of the tank, J, are attached to the rectangular plate, M, preferably by means of angle bars, P, and rivets, p, as shown in Fig. 3. It will be understood that beneath the lower edge of the plate, M, at each end of the tank, J, there is a space permitting the gas, smoke and combustion beneath the tank, J, and under the plate, M, adjoining the chamber, E, to pass into the chamber and out through the smoke stack, D. I

The grate, G, opens on the ground, that is, there is no plate beneath the grate.

In Fig. 5, I have shown an asbestos or other suitable poor conductor of heat, R, placed beneath the flange, K, and the angle bars, C, G, for the purpose of preventing any possibility of the passage of fire around the edges of the tank, it being very important that the inflammable material usually placed about the tank should be kept absolutely free from the danger of ignition.

In order to protect the contents of the tank, J, from foreign substances 1 place a cover, S, which may be made of some light metallic substance, such as tin, japan ware or other suitable material, bent to extend over the tank with suitable flanges 21, adapted torest upon the flange, K, along the edges of the tank as shown in Fig. 1.

On one side of the housing, B, I may place a bracket, T, secured to suitable cleats, m, attached. to the side of the housing by means of suitable bolts, upon which bracket- 1 place a board, U, forming a support upon which a man may stand when filling or stirring, or otherwise treating the contents of the tank. I also place a suitable bracket, V, secured to the housing by cleats, o, placed higher than the bracket, T, and carrying a plank, W', to form asupport for the. man operating the apparatus or for resting barrels thereon. lVithin suitable sleeves, '7, 8, I place a mast, 9, hin ing at one end a ring, 10, or other suitable arrangement, for attaching a tackle, by the operation of which barrels or buckets containing tar or other substances may be raised and dumped into the tank, J. F or the purpose of supporting the housing, B, I place a series of tie rods, 11, from one side to the other thereof at suitable intervals, and preferably place beveled barrels, 13, 14, from end to end of the tank for supporting the barrels of tar and similar substances during the process of delivering their contents into the tank.

For the purpose of emptying the tank or drawing off the contents when desired, I place a pipe, 15, extending from the fitting, 16, and communicating with the bottom of the tank, J, to a suitable faucet, 17, outside of the housing, B. l also place a pipe, 18, connecting with the fitting, 19, and commu 'l'llCfltlllg' with the bottom of the tank, J, near one end thereof; also communicating with a suitable faucet, 20, at the end of the tank shown in Fig. :2. By means of these faucets and pipe connections I am able to draw from the bottom of the tank the contents thereof, when and in such quantity as desired.

lVhat I claim as my invention and desire to secure by Letters Patent is:

In a portable apparatus for heating tar and similar substances, a boiler iron housing; wheels upon which said housing is mounted; a smoke chamber in said housing; a smoke stack connected with said smoke chamber; a fire chamber beneath said housing; a tank made up of one piece of boiler iron curved, with a rectangular plate at each end thereof and attached thereto; a flange along the edge of said tank; angle bars attached to the side of said housing; an asbestos strip between said flange and said angle bars; brackets on the side of said housing; a scaffold plank on said brackets; a mast; a means for securing said mast to said housing; beveled bars extending from end to end of the tank, at the top thereof, upon which the tar and other substance to be treated are placed during the process of delivery to the tank; a means for drawing out the contents of said tank, all substantially as described.

In testimony whereof I have atliXed my signature in presence 01" two Witnesses.
