BITUM'INoUs DISTRI'BUTE.

Specification of Letters Patent. Patented M313 11, 1919,

Appiicaton md september 27, i917. serial No. 193,447. E, TS www? E To all whom t may @encarna Be it known'that I, ANTHONY FRIGKER, a citizen of the United States, and resident of Cleveland, ink the county of Cuyahoga and lState of Ohio,have inventednew and useful Im-provements vin Bituminous Disy tributers, of which the following isA a description, reference being had to the accompanying drawings, which are a part of this specification. y f f The invention relates to machines for distributing bituminous material,` such 'as asphalt and petroleum products .for vroad mak-` ing. Y Y f The inventionjis more particularly designed toprovidemechanism for controlling the pressure upon-the material in the discharge manifoldby means of'a valve infa by-pass leading back to the source of supply and also for insuring'the eiicient heating of the manifold by the circulation of material through it.

The invention furtherconsists in the eral features hereinafter set forth.

In the drawings: n u

Figure 1 is a view ofthe device embodying the invention shown'inconnection with the storage or supply tank;

Fig. 2 is a section' taken on the `line 242 of Fig. 1;

Fig. 3 is a section taken on the line 3 3 of Fig. 1. 4

In the` drawings, the numeral 4 represents the supply tank for the bituminous material. Owing to the'character of this material it has to be heated by heaters (not shown) but which are well understood by persons skilled in this art.

The material from` the `tank 4 passes through a pipe 5 to a pump 6, of any suitableconstruction, from which it is delivered through a pipe 7 into the central portion of what is termed the manifold 8. This manifold is provided with a plurality of discharge nozzles y9, through which ythe material is discharged onto the road through the operation of suitable valves (not shown), one form yof valve being vshown in my copending application Serial No. 173,255, filed June6, 1917.

In applying the material of this kind it is necessary to keep the manifold heated and also to control the delivery pressure from the manifold to suit different requirements of the work to deliver more or less material in a given period through the so ai la nozzle 9'.- To accomplish this purpose I have provided a bypass pipe 10 having branches 11 leading to the ends 12 of the manifold and connected at its upper end 18 to thetank 4. vIVith this construction it will be apparent that some of the material delivered by the pump v6 will flow under pressure from the pipe 7 into the manifold and through it into the branches 11 vof the by-pass pipe 10 and thence back to the supply tank 4. and that 'there will therefore bea constant circulation of heated material through the manifold to heat the v'same and prevent any tendency of the material,

Ywhich readily congeals under ordinary temperatures, from clogging the manifold.

'i allowmaterial inthe by-pass to drain backV into the manifold and prevent clogging of the valve. The means for setting this valve comprise a lever 18 having a slot 19 at one end in which a pin 2O secured to the stem 16 is mounted and having a ball shaped portion 21 intermediate its ends seated in a ball casing 22 formed in the pipe 10 and a member 28 so that the lever 18 may be swung vertically to open and close the valve. The lever 18 also has a curved portion 24 provided with teeth 25 on its under side which are adapted to be engaged by a setting member 26 having teeth 27 and a pointer 28 and slidably mounted on the free end of a rod 29 pivoted at its lower end to the pipe 10, the member 26 being held in engagement with the lever 18 by a coiled spring 30 rmounted on the rod and bearing upon the member 26 to lpress its teeth 27 into engagement with the teeth 25 on the lever 18. f The portion 24 of the lever is provided with a scale 31 representing pressures. With this construction when the member 26 is set so the pointer 28 registers with the scale designation 5 a pressure of ve pounds per square inch will be maintained in thepipe 10 and the valve will be opened a predetermined distance While the pressure in the manifold will be such as to force the material through the nozzles 9 at best efficiency. las the member E26 is moved so as to bring the pointer 2S from the designation 5 to the designatienV 2O the Valve is opened to a greater extent and the pressure in the by-pass pipe l0 increased. While the pressure in the manifold is decreased with a resulting decrease in the rate of flow of material from the nozzles 9. Thus the valve serves to control the pressure of the material in the manifold by decreasing, the pressure in the ley-pass pipe 10. However, under Worring conditions the valve is always open to a greater or less eX- tent, as desired, so that some material Will flow through the manifold alud return to the tank and thus keep the manifold heated so that the material will not clog the nozzles 9.

The invention thus exemplifies a device for controlling` the pressure upon the material in the manifold to regulate the discharge and for insuring` efficient heating of the manifold by the circulation of material through it.

l am aware that the details of construction herein shown and described are subject to some modification and cha-nge but such changes as come Within the scope. of the appended claims l deem to be Within the spirit of my invention.

TWhat I claim as my invention is:

l. ln a bituminous distributer, the combination, with the supply tanly thereof, of a discharge manifold provided with outlet l pipingconnecting said tank with the central portion. of the manifold, and a by-pass pipe comniunicating with the supplj,T tank and having branches leading to the ends of the manifold.

2. ln a bituminous distributer, the combination with the supply tank thereof, of a discharge manifold, means for introducing material from the tank into the intermediate portion of the manifold and for conducting the material frcii the ends of the manifold back to the supply tank.

3. ln a bituminous distributer, the combination, with the suppljT tank thereof, of a discharge manifold provided with outlets, piping' rconnecting` saidmanifold with said tank includinga pump for delivering material from the tank to the manifold under pressure, a by-pass leading from the manifold to the tank, and a Vvalve in the by-pass for regulating the pressure of the material Within the manifold, said valve having drainage openings therein.

4. ln a bituminous distributer, the combination, With the suppl)T tank, of a discharge manifold provided with outlets,.means for delivering the material from the tank to the manifold under pressure, a by-pass leading from the manifold to the tank, a valve in said 1lay-pass for regulatino the pressure of the material Within the manifold, and means for permitting' drainage of the material from the valve.

ln testimony whereof, l affix my signature.
