ASPHALTING- APPARATUS.

Specification of Letters Patent.

Application filed June 4, 1912.

Patented Feb. 10, 1914. Serial No. 701,505.

To all whom it may concern:

Be it known that I, WILLIAM P. TARRANT, a citizen of the United States, and a resident of Saratoga Springs, county of Saratoga, and State of New York, have invented certain new and useful Improvements in Asphalting Apparatus, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to an improvement in devices for pouring asphalt, tar and other fluid bituminous products used in the building of bituminous macadam roads.

The object of the invention is to provide a device of this character which can be readily moved about and which will distribute the material in a thin sheet of different desired thicknesses upon the surface being treated.

I will describe my invention in the following specification and will point out the novel features thereof in the appended claims.

In the accompanying drawing-Figure 1 is a side elevation of the present embodiment of the invention. Fig. 2 is a front elevation of the same. Fig. 3 is a fragmentary side elevation, on an enlarged scale, of the pouring spout and nozzle.

As illustrated in the drawing the device comprises a tank 10, preferably cylindrical, and constructed of sheet iron or other suitable material. This tank is provided with afilling opening 12, which is closed by a cap 14. A sheet metal discharge spout 16 projects from the upper forward portion of the tank body and is permanently aflixed thereto. The spout 16 is flaring from the tank toward the discharge end thereof and is provided with a flat nozzle which extends materially beyond the ends of the tank as shown at 16 in Fig. 2. The front wall of the spout is flat and its end walls are at substantially right angles thereto, thus forming a fiat trough, the sides of which decrease in width as they approach the dis charge opening. That part of the metal which forms the front of the spout, or the bottom when it is in discharging position, is bent transversely as at 19 and back again as at 18. This forms the front or lower lip 17 of the nozzle. The portions 18, 19 may be pressed together, or, if desired, a stifiening bar 20 may be interposed and fastened between them.

The rear or top portion of the spout is bent slightly along the line 22 toward the front, and its sides are bent downward to form slides 24 which lie snugly against the opposing sides of the front trough already described. This rear portion forms a flat inverted trough 25, which is also provided with alip by bending the top of the trough backward at 26 and forward at 28 in line with the lip formed on the forward or bottom trough. I

The two troughs or lips of the spout are adjustable relatively to one another and may be held in adjusted position by bolts 30. These bolts are provided with wing nuts and extend through holes formed in the sides 24 and slots formed in the sides of the front or bottom trough. Thus by adjusting the troughs the thickness of the sheets discharged between the lips may be varied as desired.

The tank 10 is mounted with its axis horizontal and is provided with trunnions 32 aflixed to its ends and rotatably mounted in wheels 34. A frame or handle by which the device can be pushed over a road or other surface which is to be treated, is conveniently constructed of piping and comprises a pair of side bars or lengths 36 affixed to the outer ends of the trunnions 32, an end bar 38, and an intermediate crossbar 40. A support 41 is also provided for maintaining the frame of the apparatus in a convenient position when at rest and also preventing the tank from being tipped backward.

In order to tilt the tank 10, an operating handle 42 is provided mounted at one end of a rod or bar 44, the other end of which is pivotally connected to a bar 46 afiixed to one end of said tank. A link 48 is pivotally connected at one end to the bar 44 and at its other end is pivotally mounted upon the cross bar or pipe 40.

To use the machine it is filled through the opening 12 with the material which is to be poured upon the surface about to be treated. Then the cap 14 is placed in position and the machine wheeled by hand to the location where the oil or other bituminous liquid is to be applied. The handle 42 is grasped and the rod 44 pushed into the dotted line position shown in Fig. 1. The spout 16 is thereby swung forward and down near the surface to be treated, as shown in said figure at 16*, the nozzle or distributer being in an inclined position close to the road surface, the

oil or other liquid spreading in a solid sheet from the distributer and of such a thickness as desired.

The Width of the sheet depends upon the length of the nozzle which extends at least to the outer edge of the Wheel rim at each side of the device.

The pouring device herein described is especially designed for heavy rough Work such as is required for hot fluid asphalt and other bituminous substances employed in building and repairing roads. It is constructed of heavy material to Withstand considerable heat so that any material which may become congealed therein may be burned out without injury to the device itself, the parts being brazed and riveted wherever necessary to make the tank tight and strong.

By the use of this device a considerable quantity of fluid can be readily transported to the place of use and spread evenly and quickly over the surface to he treated.

What I claim is l. A device for pouring asphalt comprising a cylindrical tank closed at its ends and having axial shaft projections, wheels rotatably mounted on said projections for supporting the tank, a hand frame rotatably secured to the shaft projections beyond the Wheels a spout for the tank extending over its entire length at its inner end, flaring at least to the outer edges of the wheel rims at its outer end and having a narrow discharge opening extendlng parallel to the axis of the tank, means for adjusting the width of the nozzle discharge opening and a lever mounted on the handle frame and arranged to swing the tank on its axis whereby the spout is moved into discharging position.

2. A device for pouring asphalt comprising a cylindrical tank closed at its ends and having axial shaft projections, wheels rotatably mounted on said projections for sup porting the tank, a hand frame rotatabl y secured to the shaft projections beyond the Wheels, a spout for the tank extending over its entire length at its inner end, flaring at least to the outer edges of the wheel rims at its outer end and having a narrow discharge opening extending parallel to the axis of th tank, means for adjusting the width of the nozzle discharge opening, a lever pivotally mounted on the handle frame, a radial arm secured to the tank at one end and a link interposed between the arm and the lever. whereby the tank may be rotate-l to bring the spout into discharging position.

In Witness whereof, I have hereunto set my hand this first day of June, 1912.

WILLIAM P. TARRANT.
