The/unit 6 thus aeseribed is designed to provide afre serve supply ot the repairma-terial, such as asphalt, bitumen or th'e'like in the tank, which material is maintained in a properly heated condition either by means of the exhaust gases from the internal combustion motor, by means of electric heating unit supplied with current from the generator, or by both of said heating means. I
The rep air material is; supplied tothe road surfaces to fill up thepcracl'rs, abrasions or other cavities in the roadv surfaceor structure by means of novel form of smoothing device or iron, the principal elements of pairmedium into all of the cracks'and other w openings in the road surface or structure,
efl'e'ctan intimate union between the repair vpaired sections of the road. The receptacle 20 is provided with an inlet: 22 and. alsora larger opening 21, provided with a remov-' able cover 21'.
' to be connected by means of-a hose or-simi-,
lar flexible conduit 23 withthe discharge pipe of the tank 3, when the smoothing device is employed in conjunction With'the i tank and its accessories carried by the automobile truck; 'The covered opening 21 is to be used for fillingthe receptacle when the smoothing device is used independently of the truck, and also for the purpose of ationjis found necessary.) j The} body portion '15 of thesmo'othing device is provided with a vertical discharge 7 cleaning out the receptacle when such operorifice ll' opening into the lower or smoothing facet16 of the body, which latter isinormally in contact with the road surface during the application of'the repair material to the road. The discharge orifice is controlled by a suitable valve which may take the form a of .asliding gate 18 which-is operated in 'a' slot'formedin said body portion, said gate being controlled by a handle '19, the
outer end of which-is supported from a suitable handle or draft bar 20, by means of which'the smoothing device ismoved and directed over the particularportion of theroad surface towhich the repair materialis to beydelivered.
As'indicated, the smoothing device is fadapted to be connected'to the tank 3 by i means of a flexible hose 23, of suitable length to permit a wide range of operation by the iron or, smoothing device'to the road surface, during the application of therepair material, the saiddevice is provided a with adjustable cast'ors or rollers, which may 'p1ate's'127 -on the sockets 26 up or down,ifit' will'be apparent thatthe amount of pressure conveniently v take the form illustrated in Fig: 7; inz-whicha indicates the wheel of oneof four such rollers or castors, disposed in pairs on opposite. sides of the smoothing device, said roller being mounted in a yoke 25, slidably mounted in a socket 26, which latter is adj ustably secured to the'side of the smoothing device by means of bolts'29 passingthrough slots 28 in the plateJ27. Preferably each of the rollers is cushioned bya spring. 30' mounte'd in the, socket 26, the
' tension offwhich' spring is regulated by a set screwand follower 31 threaded into'the top of the socket." By adjustingthe foot d1? dead weight of the smoothingdevicr'di' feature the road surface maybe accurately The opening 22 is adapted;
rollers-or castors to facilitate transportation not in operation. 7
Weight of the devicemay. be taken up by the rollers. Also by movingthe adjustable socketsdownward to, the full-extent of their raised entirely out of contact with the road surface-and will supported fwholly by the of the smoothing device whenthelatter is Inasmuch as therepair'material is applied regulated and any desired poi-tionf of the 7 to the road intermittentlyandfin relatively 7 small quantities, it is in' ecessaryto maintain the temperature of thexasphalt or bitumen j containedin thereceptacle 3 at a proper uniform temperature, which may vary from one hundred and fifty to' four hundrerl d egrees, depending upon the particular -character of the material employed. It" is also necessaryto' heat the smoothing; device to a similar degree in'; order to heat the surface. r 2: 7 of the road to be treated and toeif'ect a thorough coalescence 'betweentheibindingf' f" medium and the'surfaces of' the road. structure withwhich the latter comesintofconi tact. This dual heating, function is "preferably produced by meansbf a ni electric heating device,'of any convenient or preferred form, which receives its supply of heating current from the generator8. :As'shown, the body '15 of the smoothingdevice has imbedded therein a'heating unit 14, which is adapted to be coupled up 'with the generator 7 8 by means of. suitable leads, in one of which is interposed a rheostat and switching device 4:2, meansnf which thefcurrent is l switched on and off andithe. amount of'curirent suppliedfto the heating device-441m;
latter result will be produced by the heat transmitted from the body 15 directly to thematerial in the receptacle. Obviouslyy,
if desired, the body of'the iron'or smoothingdeviceil5xmay be heated in wholeor in part by means of the exhaust gases from the internal combustion motor '5, as suitably *ja cketing body 1'5'and leading the ex- V haust-f gases from the motorthrouglr the jacket by means of a suitable flexible condui't, 'and,if' desired, boththe electric and exhaust gas heating means may be employed. f It may also be found necessary to supply heat to the repair material as -the latter passesfrom the tank 3=to the receptacle20 of thesmoothing device, in order tomaintain the" proper temperature of the material.
To effect this object, the h0se'i23 :.ma sb jacketed "to" receive the exhaustfgajses which pass from the-engine 45'through the' j acket of the tank 3, in which case the jacketf o-f, the hose 23 will beficonnected to the jacket '7 of the body 15 at the iron or smoothing de vice, so that the exhaust gases, will ass continuously. from the engineer) through the jacket of the tank 3, the jacket of the hose 2 3 and the jacket of the iron 15, from which latter they will be-exhausted to the atmos phere. Preferably, however, a special form of electric heating device is provided for the hose 23, which may be used either alone or in conjunction with the eXhaust gases from the engine 45. As illustrated in 5, the fleiiiblehose has imbedded therein or associated tierewith an electricheating coil '47, which is connected with the leads from the generator 8, preferably in parallel with the coils of the heating device 44, as Shown in the diagram of Fig. 8. v
The electric circuits for effecting the heating of the iron 15 and the hose 23 are shown in Fig. 8 as follows: from one brush of the generator 8 through lead 41 to the arm of the switch and rheostat 42, thence by lead 43 to one terminal of the heating coil 44, through said coil and lead 45 back to the other brush of the generator, branches 46 and 48 serve to connect the c oil 47 of the heating unit, associated with thehose 23, in parallel with the coil 44 so that the amount of current supplied to the heating units 44 and 47 will be simultaneously regulated by the rheostat 42. In operating the smoothing un'it alone, the receptacle 20 is filled with hot asphalt, bitumen or similar repair material, and the heating unit 44 is connected with a suitable electric supply so that the body 15 of the smoothing device is raised to the appropriate temperature. The amount of pressure to be developed by the smoothing device on the road surface is determined, in accordance with the character of the repair mate rial employed, and the supporting rollers or castors are adjustedsoas to take up the excess weight of the smoothing device. lVhen these adj ustmentshave been made and the repair material in the receptacle 20 has been raised to the proper teiri'perature, the machine is moved over the particular portions of the road to be repaired, such as cracks, abrasions or other cavities in the road, and the slide valve is moved to open the discharge orifice '17 connecting the interior of the receptacle 20 withthe lower or road engaging surface of the smoothing device or iron 15. The hot repair material flows through the orifice and into t e cavi ties in the road surface and structure, and as the road absorbs heat from the smoothing device, that portion of the road to receive the repair material will be properly heated to effect an intimate coalescence between the repair material and the road structure. The surface of the smoothing device being in intima-te contact with the road surface, it will smooth off and reduce all inequalities in the supply material and will also, in a large measure, smooth out any eXisting inequali ties inthe road surface itself when the lattei iiicludes, irrits' construction, aplastic such asasphalt, bitumen, tar or the like. In order that the repair'material may be applied only Where necessary, the smoothing device is moved and guided by the handle 2Q so that the mouth of the discharge orifice 17 will follow tlle cour'se of the cracks in the roadway or traverse back and forth over larger depressions or cavities which may have been formed in the road surface or structure'. By this means, the I proper amount of repair materialmay be. accurate- 1y distributed and. incorporated with the road surface and structure and the road surface smoothed off and compacted in a single, operation. In case the device is to be used in the application of hot or cold patchesto a road surface, including the useoffmineral aggregates, such as crushed stone, gravel or sand, the solid material, may be filled into the. cavities in the road and brought to the proper grade, after which the-smoothing device maybemoved back and forth over th'esurface of the supplied aggregate to distribute a proper quahtity of the hot binding medium thereto and effect 'a thorough compacting of the composite patch and all intimate union between the latter and the body of the road."
'lVhenit is desired to use the smoothing device to iron out existing irregularities, such as waves, shoves or, rolls in the surface of a composite road which includes a more or less viscous binding medium in the composition; the siiioothing device may be employed Without'the application of the repair inediuiii, by heating the same to the necessary temperature and then drawing the device over the irregularities in the-road sii f'face until the same has been heated and softened suiii'ciently, so that they will ef fectively iron out under the pressure imposed by the Weight of the body 15 and its accessories; Y K
Wl'ien the smoothing device is ei'nployedv in conjunction with the supply unit on the truck, it is coupled with the tank 3 by means of the hose 23 as hereiubefor'e explained and a 'suflicieiit amount of the" hot repair ma: terial in the tank is supplied tothe receptacle 20 by openingf'up the valve 11.
