Application July 20, 1937, Serial No. 154,654

5 Claims.

This invention relates to machinesfor oiling or otherwise treating roads with a surfacing material in fluid or liquid form and is particularly concerned with an improved type of header and nozzle assembly for such machines.

An objectionable feature in known prior machines for applying oil or like viscous fluids or liquids to the surface of the road is that after the oil supply is cut off from the header or from the distributing nozzles connected to the header, the oil continues to drip or flow from the nozzles to the road surface, and this not only wastes the oil but in many instances surfaces are coated or sprinkled which were not intended or desired to be so treated.

An important object of the present invention is to provide in a road surfacing or oiling machine means for overcoming this objectionable feature.

Another object of the invention is to provide a nozzle particularly adapted for road oiling or surfacing machines which drains relatively quickly and cleanly and does not require any special shut off mechanism for either the individual nozzle or the header to which it may be applied to prevent dripping after the supply is shut off from the header.

Another object is to provide a nozzle for the purpose specified which may be easily and quickly removed and thoroughly cleaned whenever desired.

The foregoing and other objects and advantages will become more apparent in view of the following description taken in conjunction with the drawing, wherein;

Fig. 1 is a rear elevation of a road surfacing or oiling machine carrying a header and nozzle assembly constructed in accordance with the features of the present invention;

Fig. 2 is an enlarged fragmentary perspective view of a portion of the header and nozzle assembly; and,

Fig. 3 is a substantial central vertical section of a portion of one of the nozzles.

Referring in detail to the drawing, the machine in Fig. 1 includes a main supply tank 5 having connected thereto oil discharge pipes or lines 6 and 6a which feed into headers I having a plurality of nozzles 8 connected thereto. As will be clearly apparent from Fig. 2, each nozzle is connected into the header along the upper or top surface thereof or above the normal oil level therein and may project upwardly a short distance therefrom. The body of the nozzle is turned in a substantially horizontal or slightly arcuate plane and is then projected downwardly and terminates in a nozzle proper. In the form shown, the nozzle body is made up of nipples 8a. and 8b the nipple 8a being threaded into the header and the nipple 81) being threaded into 8a; 5 and connected to the nipple 811 by means of a sleeve or ferrule is the nozzle proper 811. This assembly permits ready detachment and cleaning of the nozzle as a whole. Due to the particular shape of the nozzle body and the fact that it is connected to the top portion of the header 1, or above the normal oil level therein, as soon as the oil supply is cut off and pressure released from the oil supplied to the header 1, in the said body there will remain only a comparatively small or minute quantity to drip or pass from the nozzle proper 811. It will thus be seen that upon shutting off the oil supply from the header, there will be practically no dripping of the oil. Furthermore, if the machine should happen to set for a while between periods of use, the nozzles will be freed of oil automatically, preventing the latter from congealing and clogging up the nozzle outlet.

It is preferred to arrange the nozzles in staggered relation with respect to opposite sides of the header, to thereby obtain a more even or uniform distribution of the oil, the particular shape of the nozzles as a whole facilitating this arrangement. 30

It will be understood that the foregoing and other advantages not enumerated are inherent in the improved nozzle structure and that the latter may be varied in certain aspects in order to attain such advantages within the scope of the invention as defined by the appended claims.

I claim:

1. In a road oiling machine, a substantially horizontally disposed tubular header, and a plurality of-nozzles connected to said header, each of said nozzles comprising a substantially elbow shaped nipple which is tapped into the header along the upper portion thereof and projects upwardly therefrom and a discharge nozzle connected to said nipple and having a substantially elbow shaped portion which together with said nipple forms a substantially inverted U-shaped nozzle, the discharge end of the nozzle being projected downwardly and terminating at a point substantially in alignment with or below the bottom of the header.

2. In a road oiling machine, a substantially horizontally disposed header, means for supplying oil to said header, and a nozzle for discharge ing oil from said header onto a road surface,

said nozzle at its intake end connecting with the header above the normal level of oil therein and having a nozzle body extending laterally of the header also above the said normal level and terminating in a discharge end which is projected downwardly and terminates at a point substantially in horizontal alignment with or below the bottom of the header.

3. In a road oiling machine, a substantially horizontally disposed header, means for supplying oil to said header, one or more nozzles for discharging oil from said header onto a road surface, each of said nozzles having its intake end tapped into the header along the upper portion of the latter above the normal level of oil in the header and having a nozzle body which projects upwardly from the point where it is tapped into the header and then laterally and downwardly to bring the discharge end of the nozzle to a point substantially in alignment with or below the bottom of the header, the laterally extending portion of the nozzle body being above the horizontal level of the header.

4. In a road oiling machine, a substantially horizontally disposed header, means for supplying oil to said header, and one or a plurality of nozzles for discharging oil from said header onto a road surface, each of said nozzles at its intake end projecting downwardly into the top or upper portion of the header so as to communicate with the latter above the normal level of oil therein and having a nozzle body of substantially inverted U-shaped form which projects laterally to one side of the header and then downwardly to bring the discharge end of the nozzle substantially in alignment with or below the bottom of the header. 5. In a road oiling machine, a substantially horizontally disposed header, means for supplying oil to said header, and one or a plurality of nozzles for discharging oil from said header onto a road surface, each of said nozzles at its intake end being tapped into the top or upper portion of the header above the normal level of oil therein and having a nozzle body of substantially inverted U-shaped form which projects laterally to one side of the header and then downwardly to bring the discharge end of the nozzle substantially in alignment with or below the bottom of the header, said nozzle being made up of sections which are detachably connected to one another to facilitate disassembling and cleaning of the nozzle.
