Be it known that I, COLIN MAORAE- INGER` SOLL, a. citien of the UnitedStates, residing at New York city. York and State of New York, have invented certain new and useful Improvements in Machines for Surfacing Roads, Pavements, &c., of which the following is a specification, refereiice being had therein to the accompanying drawings. i p l This invention relates ltova machine for applying a liquid bonding and. surfacingniaterial to macadam or other beds of roads, pavements vand the like, whereby the ingredients of the upper stratum or` strataof the beds are bonded together and given a finishing surface through which dirt and waterdo not work.- Thev material used is preferably coal-tar or a tarry composition. Road and pavement beds l thus vtreated dry quickly after ra-infalls, and are readily cleaned and repaired. y i

Among the objects ofthe present inven-l tionV are: the provision of a surfacing'machine that is economical to construct, opera-te and maintain, and that is adapted to heat and apply hot., tarry-like bonding and surfacing material, under pressure, so that it penetrates downwardly between the macadam or other roadbed constituents, 'and thoroughly bonds and covers them; and also to make the machine in such wise that it is not dependent'on local .watersupplies for maintenance rof its principal operations dui'- ing its tours of use. i j l.

M vnew machine comprises thefollowing principal factors, which are here stated for better understandjii'gof the .followingdescription:-a wheeled vehicle; a* driving mechanismM therefor; an internal combustion engine; `an air compressor; a reservoir Ito holdtlie bonding and surfacing material; a` discharging device for such material; a

road-cleaning brush in advance ofthe `discharging device ;l and drag-brushes rearward of the discharging device; th eXh ustA gases of the engine being usedzat w ll to ieat the contents of the reservoir; the a'ir conipressor being used, at will, notuonly to supply compressed air above thecoiitey's of the reservoir and thus secure the uni ,'orin 4dis`` charge of the material undef; pressure, but also, when desired, to charge the reservoir automatically. VSuitable clutches or the like are provided toconnect and diyomect the air compressor, engine and driving-gear, so .i bustion engine mounted on the frame; I)y

in thecounty of Newv the reservoir,

lthe discharging heads ofthe reservoir.

Ar compressed air tank isv also preferably provided, between the air compressor land to supply compressed air to the upper part of the reservoir, above its contents, when the compressor is not in operation. i i

` In the accompanying drawings, illustrating the Vrinciple of the invention and the best m0 e now know'nito meof applying that the same may bev run either simultan u ously or independently as may be required.v

that principle, Figure 1 is, an elevation of the' machine, .partly in side view and partly in vertical section, at aline corresponding to line 1 1 ofFig. 3. This view also shows a container of the road bonding andsurfacing materiah exterior to the machine, and

`from which the material may be automat-- ically conveyed to theireservoir to charge-it.

Fig. 2 is an enlarged View, partly in side elevation and partly in vertical section, at

' line 11`ofFig.'3, more plainly illustrating the mechanical connection of the engine'with the air compressor and supply reservoir-,and

also the mode of mountingy and operating the road-cleaning brush.' Fig. 3 isa topplan view of the1 entire machine. Fig. 4 is :in-enlarged top-plan view ofa portion of,

the machine, parts being brokenn away for greater clearness. Fig". 5 isa rear-end view of the machine. Fig'. 6 is a vertical, sectional View, at line 6-T6 of 7, of onlevof 10'. 7 is a side elevation of one of the discharging heads.

f 10 is a side elevation of vthe road-cleaiiiiig brush, and a part of its supporting and actuating mechanism. Fig. 11 is an enlarged View more clearly showing the connections of theengine with the .road-cleaning brush and with the air compressor, and, on the lengine shaft, the actuating gear of the ve- -hicle driving mechanism. Fig. 12 is a vcr- Fig. 8 is a vertical, central view lof the air compressor, showing its inlet and the rear axle of the machine, the rear wheels of which are driven from the engine; F an air compressor; R the reservoir which con vta'ins the bonding and surfacing material; l andfC a compressed an' tank whlch 1s 1n .communication both with the air compressor engagement, bevel-gear 2 rotates with shaft l 1. Collar 4 1s circumt'erentially groovedj for reception of a pin (Fig. 2) on lever 6 pivoted at 'i' to theframe Lever 6 is connected to a controlling-rod 8 extending to the drivers seat, and there attached to a controlling-lever 9 provided with a pawl and v ratchet mechanism 10 for holding it in position to keep the toothed collars 3 and 4 connected or disconnected.

' The purpose of bevel-gear 2 is to drive the road-cleaning brush 24. Bevel-gear 2 meshes with a bevel-gear 11 en a vertical shaft 12, and its hub 13 rests on the upper side of frame A. l

Shaft 12 passes from A and through a .bearing-plate 14 between the under side of frame A and the upper side of brush-carrier 15, bei-ng provided, on the under side ot' the brush-carrier, withy a fixed collar 1G whereby, in connection with hub 13, shaft 12 is kept, from endwise movement. The lower end of shaft 12 is provided with a bevel-gear 17 which meshes with a bevel-gear 18 on the transverse horizontal shaft 19 of the brush frame. This shaft is mounted in bearings vin the opposite, downwardly extending

endhangers

20, 20 of the brush-carrier.

Intermediate bearings

21, 21 tor shaft 19 are preferably provided. Hangers 20 are provided 'each with a hook 21`'c to engage the journals 22 of the road-cleaning brush 24 when it is desired to keep `the brush above the ground.

The journals of the brush are mounted in the vertical slots 25 of hangers 20, in order to permit the road-cleaning brush to rise in ease it encounters substantial obstacles. One

of the end journals of the brush is provided vwith a sprocket-wheel 26, from which a sprocket chain 2T passes to a sprocket-wheel 2S on a'correspzmding end of shaft 19. Rotation ot' shaft l2 compels the brush 24 to rotate and sweep the road-bed.

The roadcleaning brush, when in operation, should stand t'ansversely of frame A, and diagonally in relation to the length thereof, so that thel sw-eepings may be dis-v charged to either side of the road at will.

To lock and brace the brush' supporting frame 15 1n one o r the other of such diagonal passages controlled by said valves.

positions, each side of frame A is provided with a pair of ears 29, against the under surfaces of which the upper surface of the brush frame rests and is thereby braced and locked when the brush frame is in a diagonal position and pins are through the coincident holes through the ears and brush frame.

rl`he driving mechanism of the machine for connecting the engine with the driven rear axle l) (Figs. 3 and 4) comprises a short, transverse, horizontal shaft 31 and an auxiliary shaft 31L in alinement with shaft 31, mounted in bearings 32 on frame A. The inner end of shaft 31 is provided with a fixed bevel-gear 33 which meshes with a bevel-gear 34 fast on engine shaft 1. The outer end of shaft 31a is provided with a lixed sprocket wheel 35, from which a sprocket-chain 3G passes to a sprocket-wheel 37 on axle l).

Shafts

31 and 31 are coupled together for propulsion of the im chine, shaft 31a being provided with Pa lixed coupling member 3S and shaft 31 being provided with a .slidable coupling member Si) 'cireumferentially grooved for the reception of an end 40 of bell-crank lever 41 pivoted at 42 to frame A controlling-rod til extends froin the bell-crank lever t'orwardly to the drivers seat, where it is provided with a controlling-lever 44 and a suitable pawl and ratchet mechanism. By this construction the driving gear may be disconnected trom the engine whenever desired, so that the machine as a whole may remain stationary, the. engine shaft then being t'ree to rotate, when desired, without propelling the machine, in order to operate air compressor l" while the vehicle is stationary.

Shaft 45 .of the air compressor (Fig. .11) is extended on one side in alinement with engine shaft, 1, and provided with a slidable clutch collar 4U. which is compelled to rotate with shaft 45 by a spline 46"' and which is adapted to engage with the supplementary clutch member 4i' fast on shaft 1, whereby the engine shaft and air con'ipressor .shaft are coupled together. Clutch collar `ttl has a` circumferential groove tor reception ot pins 4S in yoke lever 49 pivoted to frame A at 50. Clutch collar 46 may thus be disconnected from clutch member 47 when it is not desired to operate the air compressor.

The. cylinder of the air compressor (Fig. S) is provided with a head 51. in which an outwardly opening valve 52 and an inwardly opening valve 53 are mounted in a well known manner, head 51 being formed with From chamber 54 of this cylinder. (Fig. 1), a pipe 55 leads to the compressed air tank C, being provided, between' the '('f'in'upressor and air tank, with a shut-olf valve 50.

53 controls a pipe 5T that is open v'to the air and provided with a. shutoil' valve 58. When valves 56 and 5S are open andl the The valve' piston 59 of the compressor is given a downstroke, the air in chamber 5l is rarefied, and atmospherlc pressure through pipe funseats valve 525. permitting inow of outside l l i i l air into said chamber. On the-up-strokef of piston :39, valve 53 is seated a-nd valve. 5:2 unseated, and air is pushedthrough pipe into the compressed Vair chamber, which is f provided with a suitable pressure-indicator (it) (l the details of which are not illust ated, it not being' deemed necessary to show the construction, as the same `will be readily understood by all skilled in the art) toshow 'the pressure inthe airtank.

ln the operation ot the air compressor,

heat willhe generated, and thecylix'ider and piston consequently heated. I therefore prefer to provide the air compressorwith some simple forni of evaporatrng device whereby the cylinderniayV be cooled ;'but,`forthe reai son that machines containing my invention maybe frequently 'operated at considerable distances from adequate Water supplies, (which would be requisite for a steam-operated machine.) l do not. wish to water-jacket ration of cloth n2. As theair compressor isl only in occasional operation, this simple evaporating device servestosuticiently cool the cylinder. Trough (l'catches any drippings there may be, and by holding the drip water in contact with the cylinderfacilitates the cooling thereof. Any other evaporating or coolingv devicerinay he used if rand When any cooling` of the air compressor is neeessary.

Compressed air tank C preferably surrounds reservoir R. in order to reduce the radiation of heat therefrom, 'and is connected by a pipe 66 with the upper part of the resmwiir. The pipe is provided with a shut-ott cock GT; While compressed air tank (j forms. in etl'ec-t, a part of the conduit connection between air compressor F and reservoir t. vet the air tank isv'desirably interpo ed.heeause but little pressure of eompressed air in the upper part ofA reservoir It, above its contents, is requisite to secure av uniform discharge Yofwthe contents under pressure; and also-because the air pressure would not beso uniform if the air compressor were run continuously and piped directly to the reservir.-A Therefore. when compressed air tank C is charged, valve 5G may be closed and valve 67 opened. and 'the pressure of the compressed air in tank Cloe 0n any suitable support, a i

the material is not sufficiently forcible, valve may be opened and@ the air compressor operated. 68 is the flywheel of the coinpressor, and 69 the ity-Wheel of the engine.

lReservoir R- is provided, at its upper portion, with a .short pipe 70, which provided with a sh ut-otf cock T1; The purpose of this pipe 70 is two-fold. It'lfl allows gasesand' fumes generated in the reservoir to escape and he observed, and it is als'oused as the feed-intake of the reservoir when the latter is charged. 4When the reservoir has been properlycharged,that is, to a line soulewhat below its upper euch-and the material is heated. gases and fumes which can be-observed will es'eapethrough pipe 70, valve 711,.-

being lthenopen. The appearance of v,gases end of pipe 70 shows whenl the saine 'is sutficiently hot for mostI eti'fec'ztlve application,

and then valve Tl isclosed and yvalve GT opened to 'let in compressed air, whereby the, Vheated contents of the reservoir are forcibly expelled. through the downwardly extending discharge exit 77, at the rear end of the machine and rearwardof the/road-cleaning brush. The lower endaportion'of exit 7 7 is provided with a shut-0H 'valvev 8, which .is actuated by a controlling-rod 79;-tliat passes forwardly to a point near thedrivers seat and vis there connected with a lhand lever 80 whereby valve 78, is conveniently opened or closed. f y

To heat. the contents of the reservoir, the escape gas-exhaust 8l of the engine is provided` with a two-way dischargepipe or inuliler), one branch SQofWhieh discharges into the open air adjacentto the engine and is provided with a shut-off' valve. 83. The other branch 84e passes rearwardly into heats ing proximity or relation to theA reservoir, so that when valve`83 is shut, the exhaust. gases of the engine are availed of for heating the contents of the-reservoir. Branch 84 is pro- `videdavith a shut-,off valve 85, so that. when it is desired toturn ott heat from the reservoir the exhaust `gases may be discharged through branch 82, the valve 83 being open. Preferably, branch 84 is passed through the bot-tom of reservoir R and extended into a ehambered container 86. T his container is Within the bottom portion ofthe supplyv reservoir. A series of pipes 87 `pass from the container upwardly through the reservoir and discharge into the open air... above the top thereof. Y The cross-sectional areas of branches 82. 84, the, capacity of the exhaust- `as arrester Sound the cross-sectional areas yof pipes 87 should be snflieient to allow the exhaust gases from the engine to escape Without back pressure on the engine. rl`he arrester is of considerable dimensions, so as communicated to theupper surface ofthe to present a .Qood amount of heated surface contents of the reservoir R during` the fall l to Vthe contents of the, reservoir. It is ohtnereof 1n the reservolr. If the outlow of i. vious that such use of the hotgases 1n this i and fumes of coal-tar or the like at the open 'i I tached, by preference, a plurality of distributer-heads 89, in line one with another and of identical'.construction. Practically three distrihuter-heads are suiiicient, -and of course gone continuous 'distributer-head might be used. 'In thatcase, however, the machine would frequently discharge su eriiuous material; for example, where on y a narrow strip of the road-bed needed to be `treated This consideration applies more largely to repairing operations than it does to the initial surfacing of the road.

Flach head is preferably hinged at 90 (F1gs. ,1; y12"and 13) to the distributingpipe 88, the tubular neck 91 of the head havingatransverse tubular portion 92 which is rockably mounted in a section 93 of pipe 88, this section 93 being a transverse tubular head on the lower end of discharge 77 and inclosing the part 92, which has an opening 94C for flow of material from discharge 77 into part 92 with which the tubular neck 91 f communicates. Screw collars 95 couple sections of pipe 88 with the interposed transverse tubular head 93, which is circumferentially slotted at 96 to allow neck 91 to swing up and down in relation to distributing-pipe 88. Thus the distributer-heads will be lifted if they encounter an undue obstacle; or if it is desired to have them in raised position for any reason. A chain attachment 97 on frame A suflices to keep a head lifted (see Fig. 1). Each head is preferably provided with a bracket 98, against which the head abuts when in its lower or discharging position. A spring 99 attached to the bracket and to the head serves to hold the head in its proper discharging position against bracket 98. Each head is provided, in its tubular neck, with a shut-off valve 100. The distributer-heads are each preferably provided with downwardly and inwardly slanting side-walls 101, and are open on their under sides throughout their length for reception ofan internal roof-shaped bottom 102, the bottom being secured to the end walls of the head, and the ,long sides of the bottom being removed from the opposed edges of the side-walls 101 so as to form two continuous parallel exits 103 along the under side of the distributer-head. The inclination of each side-wall of the roof-shaped bottom to a downwardly and inwardly slanting wall 101 forms, along each side of the ldistributer-head, a trough through which the surfacing material is directed to the extending slot 104, between its ends, these slots each forming a guide-way for a slideplate 105 which projects from a slot to, into or across an exit for either opening or partially closing the same. The outer surface --of each wall 101 is provided with a vertical slot 106, through which a stud 107 extends from a slide-plate. An adjusting-screw 108 is connected to the outer endot each stud and passed through an internally threaded ear 109 projecting from the head. By turning the screw, the slide-plate connected therewith may be moved into any desired position to close or open an exit. hese discharge-heads may be made of any desired length, and, as above noted, one of them may be used in lieu of a plurality of them. When a plurality of heads are used, it is desirable that the opposite end portions of the exits 103 have endwise openings 103* (see Fig. 7), in order that the opposed end discharges of adjacent heads may intermingle, and so surface the road-bed along spaces corresponding to the distances between opposed ends of the distributer-heads. If provision of this sort were not made, then there would be danger, as will be apparent from Fig. 3, of the road-bed not being surfaced along such spaces.

The hot tarry or other surfacing material having been forcibly discharged on the roadbed, it remains to brush in this material; and for this purpose, rearwardly of the discharging-heads, two series of brushing-in brushes 110 are used. The members of each series of brushes are in line one with another, but at intervals apart; each member ofthe rearmost series being mounted opposite the 1nterval Abetween two members of the first series, so that a uniform brushing-in of the surfacing material from side to side thereof is secured. Thesebrushes are each preferably hinged at 111, at its front edge, t0 a drag-rod 112 fast at its upper end on a transverse rocker-bar 113 mounted in side brackets 114 at the rear of frame A. Brushes 110 should be fairly heavy, and may be weighted whenever desired. Their purpose is to 'compress, brush-in and finish the surface of the hot or warm surfacing material.

The road-cleaning brush and the brushingin brushes are in contact with the road surface, but use of the road-cleaning brush is not always required. To accommodate the machine to various positions when not in use for surfacing, and also to permit the brushing-in brushes to rise in case they hit a substantial obstacle, and to hold the drag-rods lay and inconvenience of heat-ing tar beforel tion of the exhaust 465 for applying dissimilarcompositions.

and brushing-inv brushes in an elevated posis tion, a cross-bar 115 is attached to-the brackets k114 and hooks 116 mounted therein for reception of the dra ply reservoir isordinarily lto be charged will vary in consistency according to their4 ingredientsand under varying tem-peramentalv conditions. Generally, however, the tar or tari-y compositions willbe more or less thick and sticky; It would ofcourse be possible to heatV the 'tar or tarry compositions, and thus render them fluid enoughV to 'be readily pumped into the-supply reservoir. In the practical 'operation of myfmachine I propose,l

however, in ordertoobviatc the expense, de-

introducingit into the reservoir, to put it up in practically air-tightcontainers'which are to be distributed along theside ofl the road Vto Abe treated,"at convenient intervals, whence it will be automatically'conveyed to the reservoir asfrequired.' Y In order to accomplish the economical and convenient charging of the reservoir under these conditions, I provide the container 200` (see Fig. l) with two bung-holes in Van upper side, and through one of them insert the nozzle 201 of a detachable pipe 202, the nozzle reaching to near the bottom of the container.` The other end of the pipe is attached to the tube of the reservolr, and valve 7l opened. Into the other bung-hole of the container I insert a short nozzle 203 of a detachable pipe 204, and attach the otherend of this'pi'pe to a compressed air-outlet 205 from the compressed Aair tank, this outlet being provided with a shut-oli' valve 206 which is opened when the charging is to .take place.V Valve ,67 being closed and valves 206 and 7l opened, compressed air will flow through pipe 204 against the upper portion of the contents oi container' 200, whereby the contents are forced through pipe 202 and pipe 7 0 into the reservoir lt to charge it, the inan-hole cover being open to let 'air out of the reservoir. The principle here involved of charging the reservoir may obviously be carried out in steamoperated road-surfacing machines; for steam from a steam generator passing through pipe 204. would push the contents of the container into the reservoir, j ust asthe compressed air does. Therefore Idesi-re to claim this feature of my invention broadly, whetherl the expansiveluid generated and availed of is compressed air or steam, or any'other eX- pansive fluid under head or pressure.

I make no claim herein for the combinay gas escape of an internal combustion engine.
