APPARATUS FOR APPLYING BINDER TO ROADWAYS.

Specification of Letters Patent.

Patented J an. 12, 1915.

Application filed April 20, 1914. Serial No. 833,129.

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 Saratoga and State of New York, have invented certain new and useful Improvements in Apparatus for Applying Binders to Roadways, of which the following is a specification.

This invention relates to apparatus for applying an oily or bituminous binder to a roadway. Specifically, the invention is concerned with apparatus for use by road patrolmen in making repairs on roadways constructed of bituminous macadain. In mak ing repairs in roadways of this character, it is necessary to fill in depressions which may be discovered, with road material, such as gravel or broken stone, and to apply thereto a binder which will hold the material in place. Ordinarily it is the practice to apply such binder by pouring the same from a dipper, but with this method it is impossible to secure satisfactory penetration, and moreover, the patrolman is quite likely to use too much of the binder. This is not only wasteful, but results in forming an objectionable hump or bump.

The object of the present invention is to provide a cheap, simple, and serviceable apparatus for patrolmens use, by means of which the binder may be sprayed on under suflicient air pressure to drive it into the interstices in the road material. This method results in obtaining a satisfactory bonding with the use of a comparatively Means are provided for heating the binding material as required for use, and for properly distributing it to any point of the roadway.

In order that the invention may be clearly understood, reference is had to the accompanying drawings forming part of this specification, and in which,

Figure 1 is a side elevation of my improved heating and distributing apparatus shown as applied to a vehicle, parts being in section; Fig. 2 is a rear elevation of the same; Fig. 3 is a transverse section through the fire pot hereinafter described; Fig. a is a horizontal section on an enlarged scale on the line 4-4 of Fig. 1; and, Fig. 5 is a complete plan view of the apparatus as shown in Fig. 1.

Referring to the drawings in detail, 1 indicates a suitable vehicle to which my improved apparatus can be attached. It is shown as in the form of an ordinary horse drawn wagon, but it will, of course, be understood that a motor truck could be equally well employed. In the wagon is carried a barrel 2, or other receptacle, in which the binding material is stored.

Carried by the vehicle and preferably located at the rear thereof is a closed reservoir 3, shown as a cylindrical drum. This reservoir may be supported by means of bands 4 attached to the wagon frame. Extending upwardly from the reservoir is a vertical pipe 5, preferably of a comparatively large size, such as an inch and a half. In the pipe 5 is included a T 6. The pipe 5 passes upwardly through a cross-brace 7, and has swiveled to its upper end an elbow 8. Into the elbow 8 is screw-threaded a horizontally extending pipe section 9, in which is included a cook or valve 10. At the outer end of the pipe section 9 is an elbow 11, in which is pivotally mounted a flange 12, riveted or otherwise secured to a kettle 13. This kettle is made of metal and preferably is of substantially the same capacity as the reservoir 3.

Loosely fitting over the pipe 5 above the cross-brace 7 is a double T or cross 14 having laterally extending arms 14: into which are threaded nipples 15 of suitable length. To the ends of these nipples are secured elbows 16, and in these elbows are mounted the ends of a pair of spaced parallel, horizontally extending arms 17. It will be understood that the joints between the various pipe fittings shown may be screwed up tight enough to maintain these arms in position, but pins or keys in the joints may be used if necessary to'prevent turning.

At the outer end of the arms 17 is mounted a heater for the kettle, which heater may be of any desired construction, and may be designed to employ either solid or liquid fuel. As shown, this heater is in the form of a pan or fire pot 18, having its upper lateral edges bent over as indicated at 19, in Fig. 3, so as to rest upon the arms 17, the pan being suspended between such arms.

While I have shown and described specific means for supporting the heater, it will, of course, be understood that in place of the pipe connections shown I may employ special castings. As above stated, the T 14 rotates upon and slides freely on the pipe 5, and

may be vertically adjusted thereon as desired. It is secured in position by means of a collar 20, provided with a set screw 21.

In order to provide the necessary air pressure to forcibly project the binder upon the roadway, I provide an air pump 22 which is shown as of a manually operated .type having a hand lever 23. This pump delivers air into a pressure tank 2 1, througha check valve (not shown) in a well known manner. The pump and pressure tank may be located at any suitable point about the vehicle. They are shown as placed near the front where the pump is within easy reach of the drivers seat.

A pipe line 25 extends from the pressure tank 24: and connects with the T 6, ,a cock or valve 26 being included therein.

A distributing pipe, preferably of small size, such for instance as one-half inch, extends from the reservoir 3. This pipe can conveniently be formed of sections 27, 27, connected together by a swivel joint 31 and having included therein a cock or valve'28.

The pipe section. 27 screws into one side of an elbow 29, the other side of which is connected with a short stub nipple 30 in such a manner that the distributing pipe can be swung around the nipple 30 as a center. At the outer end of pipe section 27 is a short section 33, connected with section 27 by means of a swivel oint 32 in such a manner as to swing in a vertical plane. The pipe section 33 carries at its lower end any suitable form of nozzle 34.

By virtue of the construction above described, the kettle 13 may be swung from the position shown in full lines, in which it is adjacent the heater, to the position shown in dotted lines into proximity with the barrel 2, so that it may be conveniently filled. The heater itzelf, moreover, may be swung in a horizontal plane and the angular relation between the kettle and heater varied as desired. This is frequently rendered necessary in windy weather, in which case the kettle is, of course, placed to leeward of the heater so that the heat will impinge thereon. Also it may be desirable to swing both the heater and kettle from one side of the wagon to the other. This arrangement makes it possible to conveniently heat a small shovel or other tool used for removing the binding material from the barrel, such material, when heavy, being often diflicult to handle in cold weather. My apparatus is, however, equally adapted for applying either oils or heavy bituminous material, such as petroleum residues or asphalt.

After the material has been heated in the kettle 13, the cock 10 is opened, the cocks 26 and 28 being, of course, closed, and the material allowed to run by gravity through the pipes 9 and 5 into the reservoir 3. If, now, cook 10 is closed and cock 26 opened, it will compact, is, at the same time, efficient and rial is discharged forcibly from the nozzle .34 in the form of a spray. By virtue of the swiveleclconnections 30, 31, and 32, it is, of course, possible to swing the distributing pipe around'so'asto reach any desired point on the roadway. This pipe when not in use is adapted to be folded against the reservoir 3, as will be apparent.

Ordinarily, after the material has been heated in the-kettle and allowed to flow into the reservoir 3, it'will remain hot as long as required for'use. However, should the material inthe reservoir 3, for any reason, become cold or stiff, I provide means for heating it. To this end a'suitable bracketis attached to the'reservoir and arranged to support thefire pan 18, or other heater. This bracket can conveniently be constructed as follows: A pair of studs 35 are screwthreaded into the back of the drum 3, and upon these studs are fitted elbows'36. Short sections of pipe 37 are attached to these elbows and a pair of arms 39 is secured to the lower end of pipes 37 by means of elbows 38. The arms 39'are so spaced that the overturned edges 19 of the pan will just fit thereover as indicated by dotted lines in Fig; 2. Thus, the same heater may be placed in positionunder either the kettle or the reservoir as required. In this connection it will be noted that when the heater is placed under the reservoir in this manner, it will also extend under the pipe sections 27 and 27, if folded against the reservoir as above described, and consequently any material which may have solidified in the distributing pipe can be thus melted out. I

From the above it willbe obvious that I have provided a very simple, cheap, and

convenient apparatus which, While light'and 110 serviceable'in operation, and it is thought that the many advantages ofthe apparatus will be appreciated without further discussion.

What I claim is:
