To all w/mm it may concern Be it known that I, SAM E. FINLEY, residing at Atlanta, county of Fulton, btate of Georgia, have invented certain new and useful Improvements in Apparatus for Spraying Binding Media on oads; and I do hereby declare the following to be a full, clear, and einct description of the invention, such as'wwill en'able, others skilled in the art to which it appertains to make and uset T ng,.:;:

is imiimiunnela' es to machines for apoil, tar, and the lik on roadways and has for its object to provideasimple and efficient mechanism, preferably in the form of an automobile vehicle, with means for applying the selected media in accuratelyregulated quantities to effect a thor- -ough andefiicient binding together fof the road material and a smooth resilient wear resisting shrface with a minimum expenditure of material and labor. To this end the apparatus i iprovided with a tank to contain the binc ing material one or more auxiliary tanks to containmr under pressure adapted to be connected with the first mentioned tank to force the oipfrom the latter at any desired regulabldpres'stire, a distribs uter header provided 'with spraying nozzles disposed at the rear of the machine and adapted to be adjusted laterally to spread the binding media uniformly and without overlaps. and also adapted to be disposed laterally to one side of the machine, sir-that a strip of'roadway. extraneous the path of travel of' the machine may be treated, without the surface of the roadway being marred or damaged by the passage of the machine thereover. These and other objects of the invention will appear from the following description in connection with the annexed drawings in which;

Figure 1 is a side elevation of the machine with certain obvious portions thereof omitted.

Fig. 2'is a rear elevation.

Fig. 3 is a similar view showing the (llS- tributer disposed at the rear and wholly to one side of thevehicle, and

Fig. 4 is a plan view of the piping system connecting the air compressor directly to a liquid containing tank and to the pressure tank arranged within said liquid containing tank.

In the application of oils, tars, and similar binding mediums to the surface of streets, highways, and the like, whether the same be a lighter application rimarilyas a dust suppressor, or to effect t e combined result of suppressing the dust and preservmg the ma way, or the em loyment of heavier bituminous or asp altic road binders in the construction of the road proper so, as to rovide. a durable roadway, con itions are equently such that to be successfully distribution of the binding material must have a wide range of adjustment,- both as respects the'quantity of binding medium applied and the particular adjustmen't or disposition of the distributing a paratus in applying the same. It is a well own fact that it is practically impossibleto obtain uniform conditions as to materials and the disposItion thereof in constructing a roadway so that even when substantial! the same character of material is emp oyed through a given road section one rtion of the surface may be of a denser ormation, while an adjacent section will beimore open and porous and, obviously, where different materials are employed in the construction of adjacent road sections the conditions of compactness and porosity will be correspondingly more widel varied, so tight different quantities of t1e bindin medium must be applied to the structure ly different road sections to efiect the desired results met the machine efiecting the the desired result on a highly porous road bed, say broken stone or gravel, such quantity would be greatly in excess of that needed to obtain the desired result where the road material is more densely and compactly applied and the excess of the binding medium would tendto'run off the road surface or to collect in pools, and thereby either unnecessarily wast thsrbindin med'um or g l i .prodifiefhighly unsatisfactory condit ons in the road surface. I

The necessity'of wide range of ad ustmeat. of the distributing means for the binding medium becomes more compelling when the apparatus is employed to distribute the different types of binding material such as is the case where a priming coat of light material is first applied and later a finishing coat of relatively heavy binder. as the quantities per unit surface of the two materials would necessarily be radirally different. Similar conditions would occur in the case of a relatively heavy binding medium applied to a road surface that has .been worked up to the desired cross-section and grade with broken stone or the like of appropriate size, in which the quantity of the heavier product would be fre uently three times as great as that of a ighter binding medium applied to the same type of construction as a seal or squeegee coat.

It is also apparent that the amount of binding material per unit surface of road wav. will vary in accordance with the speed of travel of the distributing machine over the roadway and as this speed of travel is' more or less variant, according to the condit ion of the road as to surface, grades a-nd the power of the engine on the vehicle, it is evident that the distributing mechanism must be capable of ready adjustment and re ulation to effect aproper uniform distribution of the binding medium under these conditions also.

i It is also desirable that inasmuch as the 'distrilniter cannot at all times travel in a definite path relative to the road boundaries, means he provided for taking care of the variation in the path of travel. no matter how slight such variation may be, because it is quite necessary in applying any of the various grades of binding material to avoid over-laps on the one hand, which means an excess of the binding medium at all such over-laps and also to prevent ships or on treated sections of the roadway, which would necessitate careful and individual hand treatment.

'These various conditions are met in the present apparatus by providing the machine with means for maintaining a uniform but regulable pressure on the binding medium as it is delivered from the distributing apparatus so that regularity of distribution may be effected; and also by so constructing the distributing header or manifold that the latter may be quickly adjusted within reasonable limits transversely of the machine to compensate for any divergence of the latter from the normal line of travel in either direction and thereby preventing both over-lapping of the adjacent treated sections on one hand and skips or untreated sections of the road surface on the other.

A further condition to he met in the practical treatment of roadways, especially with Irelatively heavy or durable binding medium,

a; in which the vehicle slioirid-"nbi' frnvel bvcr the road surface inunedlately in advance of the spraying mechanism. when the wheels of the vehicle would be liable to rut or displace the material of the road bed. which could not be readily worked but i to 1 ropcr surface or grade after the application oi the binder because of the relatively duiclt setting of the latter, is to provide the machine with a manifold or distributcr capable of being adjusted wholly to one side of the machine. and normal to the dircct'n:

of travel of the latter so that the vchich travels over i )Ul'i'lUIl of the roadway entirely outside of the area of distribution of the binder, \l'iththis arrangement. which constitutes an important element of the present invention. it is feasible to treat successivc sections of a roadway while preserving each section so treated at its normal surface or grade so that an even uniform application of the binding medium may be effected without a possibility of the material collecting in pools or running off the surface.

In treating roadways with heavier grades of hinder it is always necessary to apply artif'cial heat to the binding medium in order to render the same sufficiently fluid to be sprayed uniformly from the nozzles and if for any reason, as by stoppage of the machine, the binding medium tends to cool in any part of the conductive system between the tank and the distributing nozzles it will congeal and obstruct the various nozzles. particularly the nozzle outlets, by the action generally known as freezing and a'good distribution cannot be subsequently obtained until after the obstructing material has been again reduced to the nee essary condition of fluidity. Means have been made to overcome this ditliculty by providing a connection from the exhaust of the engine which drives the vehicle to the 'distributer' manifold or spray header so that when the binding medium freezes in the distributer, the hot exhaust gases from the engine may be forced through the header to heat the congealed material and allow the same to drain out of the entire header system;

it will. therefore, be seen that the present invention is designed to meet the mostexacting conditions of road treatment with all types of binding material from the lightest to the heaviest and to apply the same in accurately regulated minimum quantities per surface square yard ranging from one-eighth to Ol'lQ fOilI'tl'l of a gallon for light oils or tars up to a maximum of from one and a half gallons to two gallons per surface square yard on highly porous broken stone or gravel road surfaces, and at the same time assuring uniformity of distribution.

forni of conical sprays, on to the road sur- Referring to the accompanying drawings, 1 indicates the chassis of an automobile vehicle provided with wheels 2 and 3, the

of a transgse partition 11, the former forming a eptacle for the binding material and the iatter an'air tank for containing air under relatively heavy pressure, which is ultimately to be delivered into the chamberlO to force the binding material there'- from and into the distributing header, by means of which the material is forced, in the face.

Located, laterally of the main tank are auxiliary pressure tanks 50 and 51 which are also adapted to retain air under relatively heavy pressure and to deliver the same as may be desired to the oil receptacle 10. Preferably the pressure of the air in the several tan its 11, 50 and 51 is maintained at a point much higher than that required to force the 'hifldi-ng material from the tank 10 and thrqtl 1 the spray nozzles in the desired 0 effect an even distribution, and the neary pressure-is maintained in all f the tanks or receptacles by means ir compressor 52 mounted on the in advance of the main tank, and

- .ch ss dvgie from a shaft 4 which may be either th main shaft between the engine and the ansmission, or a jack shaft suitably coupled thereto. .As shown, the shaft 4 is provided with a clutch consisting of a fixed member 57 and a loose member 56 which are broughtinto engagement by a suitable lever mechanism 58 when the compressor 52 is to be operated. The clutch section 56 is provided with a sprocket gear 54 which is con nected by a drive chain 53 with asprocket wheel on the shaft of the compressor.

he outlet side of the compressor 52 is connected b pipe 60 with a i'p'ing system delivering t e air either direct y to the tank sec'tion'lO or to the compressed air chamber 11' of the tank and said pipe 60' is rovided with an ordinar stop valve 61 an a check valve 62, beyon which branch pipe 63 connects at 63' to pressure chamber 11 and branch is connected to the upper portion of the dome 12 of the main chamber with the pressure regulator 66 interposed to accurate-.1}- regulate and fix the air pressure admitted to the section 1.0 of the tank which contains the arund trcating medium. Between the pressure regdm'or66 and the connectien between the pipe 85 and the dome 12 is a check valve 67 which is'elfective to preventany gases or liquid material passing backward from the tank section 10 to imriiir the eiliciency of the pressure regulator. e

coupling between pipe sections 63 and 65 is provided with a stop valve (34. The discharge pipe from the compressor 52 is also connected with the auxiliary air tanks 50 and 51 by means of flexible pipe sections 60 and detachable coupling members 61 so that the auxiliary tanks 50 and 51 may be charged simultaneously with the air chamber 11 of the main tank, or may be shut off or disconnected at will.

" The auxiliary tanks 50 and 51 are connected by cross pipe 62 provided with stop valves 64 and 65 on opposite sides of a connected pipe 66 provided with a stop valve 67, which latter pipe is connected to the top of the dome 12 and is provided with pressure regulator 68 and a check valve 69,

which latter serves the same purpose as check valve 67 in preventing volatilized or liquid material from the tank section 10 passing upward into the pressure regulator 66. An over-flow pipe 70 provided with a suitablestop valve 71 is connected to the dome 12 to permit discharge of accumulated pressure in the tank when the latter is being filled with road material and also to permit the escape of any excess of the binding material when the properlevel in the tank section 10 has been reached.

lVith the described arrangement of the compressor and air tanks it will be apparent that the necessary and properly regulated pressure may be applied to the surface of the binding material in tank section 10 from any or all of the'air reservoirs 11, 50 and 51, or if desired, directly from the compressor.

.For example. when it is found desirable to pressure he delivered by the compressor 52 fall below the necessarypoint for any reason. When it is found necessaryor desirable to use the compressed air in tanks 50 and 51 the valves 64', GS' and'GT, are open. thereby admitting pressure from both of said tanks 50 and 51, by way of cross pipe 62 and vertical pipe 66 to the upper portion of the dome 12, the pressure equalizcr or reducing valve 68 serving to admit the desired working pressure to the tank section 10.. If it is desired to use the air pressure from one of the tanks 50 or 51 only the appropriatevalve 64 or 65 is closed. The several air tanks and the main tank are provided with suitable pressure gages and stop valves to indicate the desired pressure and also to prevent over-charging.

This arrangement admits of an exactly predetermined and uniform pressure to be maintained on the material in the tank sec tion it to insure the uniform distribution of the material from the spray nozzles ot' the 5 distributerhead. and thereby etl'ect a prop erly regulable distribution of the binding material to the road surface. and as this pressure is supplied from any one of the series of air tanks or receptacles, which in tllll] are kept charged to a pressure largely in excess of that normally required in the tank section 11). it will be seen that any desired pressure in the tank section 10 may be obtained and maintained, without variation,

such as would be produced by pulsations of the compressor, by a proper adjustment of the pressure regulators or equalizer valves (56 and (58.

Connected to the bottom of the tank section 10 is the outlet pipe 14 provided with a stop valve 15 to the lower end of which pipe 14 is connected a drain valve 16 and a hori zontal pipe 17 which latter is provided at its rear end with a st-op valve 17 and a cow pling member 18. Avertical pipe section 19 the horizontal frame members of the chassis are two angle bars 1', 1' which extend rearwardly of the chassis and serve as supports for two yoke members 25, 25, which are con nected by a bridge piece 31, so that said yokes and ridfie piece are capable of longitudinal movement alon the angle bars 1', 1. Slidably mounted in t e yokes 25, 25 is a header support 26 generally tubular in cross section and having an intermediate rack section 27, in which sup ort 26 the pipe 21 is secured so that said pipe 21 partnkes of any later i movement of the support.

Mounted on the bridge piece 31 is a housing piece 30 in which is journaled a vertical shaft 29, on the lower end of which is mounted a pinion 28 meshing with the rack 27 carried by the support 26, so that when said shaft 29 is rotated by the means of the hand wheel on the up or end thereof, the support 26 is moved to t e right or left according to the direction of the rotation of said shaft. thereby moving pipe 21 transversely of the machine to a corresponding extent. Each section of the pipe 21 adjacent the connec- 5 tion thereof with pipe 19 is provided with a cutoff valve indicated at 24 and 24' respec tively. so that the material delivered tron. the tank section 1 may be directed toward both ends of the pipe '21 or toward one end 60 only, accordingly as both or only: one of tievalves 24 and 24' are open or closed.

The outer ends of the pipe 31 are provided with T couplings 22 having; plug caps in the outer ends thereof and having short pipe sections 23 connected to is; downwardly extending branches. The lower ends zontal parallel pipe sections 45 and l? which have disposed longitudinally thereof a series of T couplings or unions 40 to which are connected suitable nozzles 46 and 48 for delivering conical jets or sprays in a vertical direction. The couplings 40 and the connected nozzles are disposed in staggered relation on the respective header pipes 45 and 47 and the latter are disposed at such an elevation above the ground that the conical sprays or jets of the binding material delivered by the several nozzles are successively contiguous when they reach the ground but do not materially over-lap, so that the binding material is applied to the road surface as an even uniform layer.

In the normal operation of the machine, the distributor occupies the position shown in Fig. 2 with the jet nozzles disposed equallv on both sides of a vertical medial, line of the machine so that the road treating material will be distributed in a uniform sheet directly behindthe machine having a width equal to the lateral range of the outer sprays on each end of the distributing! header. In turning curves in roadways and in avoiding obstructions it is desirable that the distribution of the oil in a lateral direction be varied and this operation is effected by rotating the shaft 29 in the appropriate direction which moves the carrier 26 a"d the entire header to the right or left, according to the direction of rotationot said shaft 29. An operator standing on the rear of the machine and observing lhe distribution of the oil on the road surface by the jet nozzles, by appropriately movin; the header to the right or left, through the agency of shaft 29 and carrier 26, may quickly adjust the header laterally in either direction and to any extent up to the limits of movement of the carrier 26. so that the outer marginal edge of the layer or coating of oil may be made to follow any desired path. so a: to conform to the prescribed lateral limit of the roaduav. to avoid obstructions or poo tions of the roadway not to be treated and also to conform to the meeting edge or lateral llmit of an adiarent strip or stretch oi" roadvrnv already treated wi hout ov-r-rhipping, The lateral movement of the header and its support is rendered pos ible by reacon of the flexibility of the pipe joints below the valve 15 in the outlet connection oi the. tank section i l and as the y kcs 23 slide freely on the angle bars 1, the lateral ad- .justment of the header may be effected without undue strain on the mechanism.

When the s raying operation is suspended for any length of time, if the road treating -materi'al is of a character required to be heated to reduce it to the necessary degree of fluidity, it tends to freeze or congeal in the header manifold and the connections between the same and the tank, thereby renderin it diilicult to start the machine again without first clearing the header and its connections of the congealed material. In order to avoid this objectionable feature provision is made for connecting the header with the exhaust of the engine which drives the vehicle. To accomplish this and also to prevent connection between the header and the engine exhaust when the machine is spraying, the header is adapted to be swung rearwardly and upwardly until the pipe 45 is engage by hooks 80 pivoted to the rear end of the angle bars 1', said swinging action being effected at the T couplings which support the header from the ends of pipe 21. The T coupling 22 adjacent the rear end of the exhaust from the engine is provided with an angularly disposed coupling 82 having a sto valve 81 associated therewith, which coup ing is adapted to be engaged with the mating coupling member 83 on'the end of a flexible pipe section 84 attached to the discharge end of the exhaust pipe 7 of the engine, so that when the header is swung up into engagement with the hooks 80 the COllJilllg member 82 is in position to be engaged by the cou 'ilinginember 83 on the end of the exhaust pipe. After this coupling is effected the hot gases of the exhaust traverse the header and its various connections and prevent the road treating material from congealing and ultimately forces Such material as may remain in the header and its connections out of the nozzles, so that the header will be free of all obstruo tions and ready for subsequent usev in order to prevent the possibility of connecting up the pil supply with the header while the exhaust connection from the engine is coupled to the header it will be noted that before the header can be swung to its lower operative position connection between the engine exhaust and the header at coupling s2 and 83 must be broken. This arrangcnn-nt is found necessary and desirable inasmuch as a careless attendant might leave the inlai- 81 open whenthe header is swung to operative position, thereby permitting the real treating material to be forced into the engine through the exhaust connections. lly disposing thepouplin member 52 in such relation thatftlle heater cannot be swung into operative polsition until the connection at 82 with the exhaust pipe is broken. film danger is entirely obviated and even it the valve 81 is accidentally left open no more serious result than the wastage of a little of the road binding material would ensue.

Under certain conditions it is found desirable, if not imperative, to apply the binding material to the surface of a road which has notflbeen traversed by the wheels of the machine, as the latter would tend to mar and rut the surface under certain circumstances, such as are pointed out in my companion application filed concurrently herewith, Patent No. l,3i1,458, granted May 25, 1920, and to adapt the present machine to such an operation the header is so constructed as to ermit its application and dis position who] y to one side of the macgne without, however, interferin with the 01'- mal lateral adjustments of the header as hereinbefore explained.

The particular means for effecting this re- 85 suit are illustrated in Fig. 3, in which the header is shown as being disconnected from the left end pipe section 23 and rotated through 180 degrees on 'the right end pipe section 23 and an auxiliary pipe section connected to the right end T coupling 22, said auxiliary pipe section having an outer angle coupling 91 with a short vertical pipe section 92 adapted to be connected with coupling 44 to pipe section 42 at the extreme outer end of the header. A suitable tie rod 93 connected to the coupling 91 and to a bracket 35 on the support 26 serves to brace and support the header in the outboard position shown. It will be noted that with this disposition of the header the distribution of the binding material to the road surface is entirely outside of the line of travel of the vehicle wheels so that said material is a 3 plied to the smooth unbroken surface of tl i road.

When the header is adjusted laterally of the machine as shown in Fig. 3, the supply of road treating material from the tank 10' is delivered through the right end section of pipe :21 and the opposite section of said pipe is cut oil at valve 24:. \Vlien it is desired to dispose the header on the opposite side of the machine the same mode of procedure s followed as heretofore described, except- "hlit the header is swung on the left hand T coupling 22 as a pivot, after the right end of the h ath-r has been disconnected at cou- 3 lin til. lipe section ill) is then connected 1 s h it end coupling and the outer end tin; iii in as before. 'hen so arranged heaih r ll i'listribute oil laterally of and to the left at the machine. When 1t is de sired to the header back to its normal ition at the rear of the machine auxiliary (action till is disconnected and the header no on leftmnd T coupling 22 as a pivot un il in coupling member 44 comes opposite i; r in and pipe section 23 when the coufittiull is rfl'ccti d and the header is then in proper position disposed transversely of the rear of the machine. It will be particularly noted that the lateral adjustment of the header by means of the gear and rack 27 and 28 is possible for any of the three dispositions of the header, namely, at the rear of the machine or laterally and to the left or right thereof, for the reason that the header is supported in the carrier 26 at all times and moves with the latter.

From the foregoing it will be apparent that the machine possesses a wide range of adaptability to meet substantially every condition in road treatment with oils, tars, and the like, and is well adapted to the application of a uniform distribution of the road treating materials exactly where the same are needed and because of the accurate control of the uniform pressure applied to the bindin material and the ready adjustability of the eader, the application of the binding medium of the road Surface may be effected with practically mathematical precision, both as to the quantity of material per unit of road surface and also as to the exact superficial road surface to be covered, the boundaries of which may be followed with great accuracy by appropriately adjusting the header by means of hand wheel shaft 29, as hereinbefore described.

\Vhen it is desired to fill the tank with the road treating material the valve 71 in the over-flow pipe is opened to permit the accumulated air pressure to escape. the valve 20 in the supply piping from the tank to the header system is closed and a connection to the source f supply of the material is made at the coupling 18 on the end of pipe 17 so that the material may be delivered either by gravity or by suitable pressure appara tus into the tank, and when the desircd amount of material has been admitted to the tank the valves 71 and 17' are closed and the connection to the source of supply brokcn at coupling 18. The vehicle is then transported to the place of application of the road material and meanwhile the requisite amount of air pressure is admitted to the tank section 10 and the apparatus is ready' for operation. after the header has been dis connected from hooks 80 and swung to its normal vertical position, as hereinbefore explained.
