' win fully a pear by a specification and claims.

This inventionrelatesto a roadoiler, and par ticularly to'the constructionianda mountingiof the spray bar which extends transversely ofthe supporting vehicle and the road; and fromwhi-chfl the oil isdistributed onto the latter. s 4 I The principal, objects of my invention areto providea spray bar unit so mounted that'it may be adjusted laterally a well as vertically oftthe supporting vehicle; one having ganoperators platform mounted on and adjustableswith the unit; and one having horizontally.foldabie end portions.

By reason'of the features above'generally defined, shoulders or other laterally offset areas may be readily oiled without the vehicle also riding the shoulders; then-operator ishin position to seeand control the oiling; operation as it'takes control valves Idepen'd from pipes -I and {the place; and the overall width of the spray bar may be quickly reduced for transportation. and

the like. v v ;j .7: .s .7 The device may be used for emulsion as well A further object of the invention sltofprodiiee a simple and inexpensive; device and yetvv'one which will be exceedingly efiectivefor thegpur pose forwhi'ch it is designed; 1 ,j v

Referring now more particularly tothe char- I acters of reference on the drawings the spray bar comprises: a central section ofheavy" pipe I,

corresponding gems in the several valve having individual con'trolvlevers 6- projecting "upwardly from the {valves behind the pipes and adapted to be moved-by the feet of the operator .when" desired or all as usual by mechanical control means. tswivel' elbowsl-are mounted on the outerend of' pipes 2; a length i .of flexible hose 8 extending fromeach'elbow to" the usual oil circulating system- (not shown)?

as will be evident.

The spray bar is shifted laterally of; its sup-' porting structure, and independentlyof its; raising and lowering, by the following a means:

The hand wheel and crank handle are laterally offset so as not to interfere with each other. Shafts 26 and 24 areconnected in driving relatio within housing by gearing 28.

: In order to hold the foldable pipe sections 2 either in extended or folded positions, the following arrangement is provided: Secured on and projecting forwardly from pipe I adjacent its ends are brackets 29 having lateral outwardly projecting saddle extensions 30 at their forward end adapted to engage over one-half of pipes 2 claim as new and useful and desire to secure by LettersPatent is: i

1. A road oiler comprising a spray bar havingaf plurality of sprayunits depending therefrom and which include individual control valves, individ ual control levers projecting upwardly from the valves rearwardly of the ba'r, means supporting the bar clear of the ground; an operator foot platform extending lengthwise along the 'bar disposed rearwardly of said bar and the levers below the level of the top of the latter to position said levers for foot operation and -means mounting the plat- "form in a, fixed position with the bar.

when the latter are folded back so -as to 'be at i right angles to pipe I, as shown-in Fig. 1. 7 Each pipeZ carries an upstanding stud 3ladapted to engagein a horizontal slot 32 in the corresponding saddle extension 30 when said pipe 2 is folded;

a clamping handle nut 33 'gbeingthreaded on said stud above the extension soithat pipe 2 maybe. releasably clamped against. movement from a folded position. i a To hold each pipe 2 from foldingwhenextended, a brace bar is permanentlypivotediat "one end on the corresponding saddle --extension 30 laterally in: from slot: 32 and at the other end is notched in one side as at 35 to "engage stud 34' also under nut '33 when pipe 2 isextended, as shown in Fig. l. V 1

In orderxto support an operator from'theispray bar unit, rearward-1y. extending brackets" 38 are mounted onlpipe [in widely spaced relation.- As.

clearly shown ln.FlgS.f3' and 4, the forward portion of these loracketsls above and clear of valve levers 6, and the brackets then extenddownwardly a "certain distance ahead of their rear horizontal portion 36d on which the platform 31 is supported. In this manner, the levelofthe platform is below that of 'the'upper end of levers 0 so that the latteryare 'exposed aboveiand infront of, the feet of'the operator,-which may thus be usedt'o manipulate the valves. A han'd rail limit 38 is mounted in connection withthe platform for .theconvenience' of the operator. g Q From the foregoing description it will be readily seen that I-have produced such a device'as substantially fulfills the objects'of the invention as set forth herein: 1
