APPARATUS FOR SURFACINGROADS AND THE LIKE.

Surfacing Roads and the Like, of which the.

following is a specification. I This invention relates to an apparatus for treating the surface oi roads, pavements and the like. I

The principal objects of the invention are to provide a practicable and convenient combination of parts {or the purpose to take the place of the ordinary crude c j nstruction used for that purpose; alsoto provide such a combination with means whereby powerfrom the road roller can be taken directly to a motor or engine carried along with the road roller but detachable therefrom; to drive a pump for forcing' the surfacing ma- .terial from a tank in a uniform manner through the nozzles under pressure; to pro-r vide means whereby the' molten material from the tank will be heated by exhausted steam front. the engine throughout practically all its travel from the tank to'the nozzles and even while it is in the nozzles; to

provide a series of practical and'etlicient connections between the tankand pump and between the pump andnczzles for accom- Vide a construction in which an operator can take up a posit-ion so as to control the discharge of road surfacing material through the nozzles and also control the position of the nozzles relative to the path over which .t-heroad roller travels; to provide a convenient mechanism by which the nozzles can be arranged in a plurality of sets and the liquid turnedon to all of them at once or to only one or more of the sets, as desired; to provide an improved way of connecting the tank'with the roadroller so arranged that when disconnecting the parts the drippings of molten material willbe deposited directly on the ground and to provide improvements in details of construction as will appear hereinafter.

Reference is to be had to the accompanyiiig drawings in which-f 1 Figure 1 is a side elevation of a road surfacing apparatus constructed in accordance with this invention. Fig. 2 is a similar View on enlarged scale with parts in section of the rear vehicle shown in Fig? 1 and the elements mounted thereon. Fig. '3 is a rear end elevation of the same. Fig. 4 is a horizontal sectional view of the line 4-4 of Fig. 3.

Fig. is a plan of the connection between the tank vehicle and rear vehicle, and Fig.

(3 is a side elevation of thesame with parts broken away. 7 Qeveral devices have been invented, and

some of them have been constructed, for the purpose of treating the surfaces of roads with asphaltuin oil, bitumen, and similar road surfacing material, but they have generally been of a comparatively crude and incompleteconstruction so that, the material h as not been uniformly distributed and much of the time of the gang of men employed has been wasted, and the, full elliciency could not be obtained from the road roller and other parts of the apparatus. Forthe purpose of overcoming these defects and securing the objects which have been mentioned, this invention is made.

The invention isillustrated in a form in which a road roller A of any usual construct-icn and therefore not illustrated in full hcreinbut shown asstcam operated, is connected up by means of a remo *ablc tongue 10 with a vehicle B on which is located a tank C for containing the oil or other road surfacingmaterial. Connected tothe rear of the vehicle B by means which will be described hereinafter is a-third vehicle D shown as having only two wheels. On this is mounted arotary pump E for taking the material from the tank 0 and discharging it through nozzles F. This pump is shown.

as operated by a steam engine Gr receiving steam from the road roller. By providing a series of elements of this character it will be seen that each device is complete in itself so that a tank that has been emptied can he rei moved tlIltlJ'GtlllDGd to a place for being filled while another one is substituted so that the work goes. right along without material interruption. Thus each element can be used with maximum of ellicicncy. For the purpose of practically connecting; them up so as to accomplish these results, the tank vehicle is provided with a steam pipe '11 connected by a flexible hose 12 with a live steam pipe 13 from the boiler of the road roller. Consequently the pipe 11 is provided with live steam. It in its turn is connected by a flexible hose 14 with a steam pipe 15 supported by the vehicle D. This steam pipe leads to the steam inlet of the cylinder 16 ot' the engine G, the piston rod 17 of which is connected by a crank shaft 19, pinion 2t),

and gear 21 with the rotary pump E. A fly wheel 23 is shown on the shaft 19. The details of the pump need not be described as any form of rotary pump can be employed, but it will be understood that the rotary pump is used for the purpose of securing a uniform instead of a pulsating pressure and consequently, a uniform flow of the liquid surfacing material as will ap pear hereinafter.

The vehicle D is drawn behind the tank vehicle partly by means of the pipe connections which connect the interior of the tank with the intake of the pump. For this purpose the tank is provided with an outlet pipe 25 having a valve 26 for controlling it and that is connected by pipe fittings 27 with a flexible hose 28 adapted to be supported when not in use, by a hook 29 on the vehicle D. The hose is connected with a. pipe 30 which leads into the intake 31 of the pump.

The vehicle D is provided with a fixed forward projection 35 on which is pivoted at 36 a movable tongue 37. This tongue is connected by a pin 38 with a bracket 39 fixed to the straight branch of a Y forming part of .the pipe fittings 27. Consequently the vehicle is drawn along with the tank vehicle. In order to control the direction of motion of the vehicle D so as to keep it properly in position, a curved rack 40 is mounted on the rear end of the tongue 3.? and is caused to mesh with a pinion 41 on a. rod 42 at the top of which is a hand wheel 43 within reach of an operator standing on the platform of the truck D. Also in reach of the foot of the operator is a pawl 44 normally forced by a sprin 45 to engage the teeth of the pinion 41. imply by manipulating this pawl by means of the foot the operator can control .the direction of motion of the vehicle D by .the hand-wheel 43 and when he gets it properly into line with the road roller he can leave the pawl alone and it will hold the tongue in position.

The material from the pump passes through a pipe 50 into a horizontal outer chamber 51. This chamber is provided with a plprality of outlets.52-52 2 each one fitting into a section 53' of the distributing trolled by a separate valve 55.

pipe. The three sections of this pipe shown in the drawings are connected with each other by couplings 54 having valves 54* therein so that they can be connected with each other or separated, as desired. \Vhen separated each one of the pipes is.con-

Each of these valves has an arm 56 for operating it, these'arms being-connected with an operating lever 57 by means of a series of links 58, one for each arm. One of these links is shown as connected directly with the lever 57 by means of a hook 59 which engages a pin (50 on a projection on the lever. Another one is connected by a similar link 61 with another pin (32 on the lever. The lever is provided with an opposite projection having a pin 63 with which a link 64 connected with a third lever 56 is connected in the same way. Obviously this lever 57 can be connected up with either one, two or three of the valve operating arms so as'to supply the liquid material from the distributing chamber 51 to the desired number of sections of the pipe 53. The latter is provided withv a plurality of openings (38. In each of these openingsis the nozzle F of any desired kind.

'In order to provide a safety device for preventing any damage in case the nozzles get stopped up, a by-pass is provided from the pipc50 back to the pipe 30 and in this is located a relief valve 76 which, under ordinary pressure, will remain closed but will open if the pressure becomes excessive and allow a circulation of the liquid down into the pipe 30.

Inorder to provide for keeping the molten material warm enough so that it will flow readily the exhaust pipe 80 of the cylinder 16 is directed through a valve 81 .into a jacket 82 surrounding the supply pipe 30. The outlet 83 of this jacket is connected with a passage or chamber 84 which extends along the pipe 53 so as to heat the material just before it exudes from the nozzles. A by-pass 85 is provided with a valve 86 for cleaning out the pipe 30 with exhaust steam if desired. The pipe 53 has a clean out connection 87 from the pipe 14 and a clean out plug 88, so that it can be cleaned out by live steam.

From what has been stated it will be seen that an apparatus for this purpose constructedon the principles above illustrated, whether in the form shown or not, is a practicable andeificient machine for the purpose intended and that the steam employed for the pump is economically used as the exhaust thereof is employed for keeping the oil in a condition for flowing readily through the pipes and nozzles. It'will be seen, also, thatthe device is designed forthe purpose of securing-a high eiiiciency in the operation thereof and in the employment of the labor of the gang of men who work withit. It

and the like, the combination with a tank,

at the rear of the tank having a tongue. and

will be seen also that for the operation of the machine itself, only the men are required who operate the road roller and one other to stand on the vehicle D, steer it, and control It will be observed that a feature of importance lies in the provision of mechanism whereby an attendant, standing on the frame or draft tongue of the trailer, may steer the hicles, whereby this attendant Will have entire control over the trailer-independently of'the attendant who is controlling the steam roller, so that the attendant on the trailer may be deposited close up to a track rail or to the adjacent edge of a previously coated portion of the road-way, This is a very important function in that it avoids spreading vents overlapping upon previously coated surfaces. It is important that this control of the trailer shall be exercisable at a point on the trailer, where the attendant may mainissues from the nozzles. It will be observed also that a feature of. importance in this machine lies in the fact that the tankvehicle may be readily disconnected from the train connection between the steam engine on the roller and the steam engine on the trailer employ several tank wagons and thus keep ing material. It is essential that the sur/ facing material shall be previously heated to a liquid state. This heating process r cquires considerable time and often has to be,

observed that the work is much expedited and important economies ettectedby having several'tank wagons so that while one 1s may be in the act of loading or heating or in transit. In this way'our apparatus may be kept practically in constant use so that the force of men accompanying the apparat busy practically all the time.
