5 over the surface of a road.
' The present invention is intended for use in the construction, repair, and maintenance of roads made of sheet asphalt, asphaltic concrete, macadam, brick, or any other pave-V 0 ment upon which fluid or semi-fluid asphalt,
tar, or other bitumen, or Portland cement grout, and the like, are spread, The useful life of such road pavements depends upon the denseness thereof, that is, upon the absence, or a minimum, of voids and interstices, in order not to admit moisture which, upon freezing and expanding, acts 'to crack the pavement, and then upon thawing, permits the same to rot. lt is therefore, desirable that the particles of stone and the like` be covered and impregnated with the asphalt or other cementing agent. A pavement too badly worn to be repaired, must be ripped out and replaced, and this is so costly that the desirability of applying a penetration coat and a sealing or enlivening coat of asphalt which effectively renovates the pavement and greatlylengthens its life, is now well recognized.
The object of the present invention is generally, to provide anv apparatus making it possible to obtain a uniform coating of road surfacing fluid fluid over a pavement, which is effectively forced into the voids and interstices of the pavement, but which will'not form puddles or mushy places which are annoying to vehicular andpedestrian traffic.
Heretofore, when road surfacing fluid was spread upon a road, it was not applied with sufficient force to penetrate appreciably below the surface of the road, and most of the fluid was not effectively utilized to seal the pavement. Accordingly, one object of the present invention resides in the provision of an apparatus which will transmit a vertical pressure to the fluid, in order to force it into ypresent invention is to devise suitable means Serial No. 476,865.
the irregularities, voids, and interstices of the pavement, thereby renewing their cementation by replacing old, rotted, and decomposed asphalt or cement and the like, with fresh sealing fiuid. 59 lt has sometimes been attempted to obtain pressure on a spreading device by means of the weight of a tank of the fluid being` distributed upon the road, but the pressure ob tai ned by this method is a variable, dependent upon the amount of fluid carried at any one time. @ther systems sufferfrom similar defects. Another object, therefore, of the for making the pressure of the spreader, and 16.0
more particularly the vertical pressure, the desirability of which has already been outlined, substantially constant in value.
it is ordinarily attempted to spread the road surfacing fluid by means of brushes or brooms, either by hand or by mechanicaloperation, but such devices suffer from the defeet that the bristles have a tendency to re.- move or dig out the liquid from between the stones or aggregates of the road, thereby in- `iuring, instead of improving, thedesired seal- Ying action of the liquid, and still another object of the present invention is to provide a spreader which will obviate this defect and which will permit a generous filling of the liquid `to remain in the cracks and voids of the pavement.
TWhile it is desirable to fill the small crevices and interstices of the pavement, it is undesirable to permit the liquid to remain in bodies of large area, for the consequent rpuddles are wasteful of the road surfacing material and are exceedingly annoying to ve hicular and pedestrian traffic. Even when such puddles solidify, they remain mushy and form an unsatisfactory road surface. It is not easy to avoid the formation of such puddles because of irregularities in the surface of the road, together with other factors such as changes in speed of the distributing truck, clogging of some or all of the nozzles in the spraying apparatus, variations in the pressure Within the tank from which the liquid is forced to the nozzles, as Well as irregularities caused by inexperienced operation of the distributing truck. Still another object of my invention resides in the provision of a spreader which will permit the liquid to fill small crevices and voids in the pavement, and yet which will push or sweep the material spread on the surface of the road so as to distribute it evenly and to preventthe accumulation of excess material in spots in order to avoid the formation of puddles When the road is wavy or corrugated, such of the material as is not forced into the pavement being carried ahead until usefully absorbed by the pavement.
Roads are ordinarily crowned to facilitate,
drainage, and this alone enhances the difliculty of obtaining the desired uniform coating ofV asphalt or the like. Sometimes engineers and contractors attempt to avoid distributing the asphalt at the edges of the road, and depend upon agravity How of asphalt from the central portion of the roadtoward thc sides thereof. Considerable manual labor is subsequently necessary to attempt to obtain'an even distribution of the liquid at the side portions of the road, and even so, it is not possible to obtain the desired penetration of the liquid into the pavement, for the liquid already has time to partially cool. In accordance `with still another object of myv invention this diiculty is overcome by the provision of a spreader which is designed to accommodate changes in the configuration of tliie road so as to take care of the crown thereo lVhen brushes or brooms are used for spreading asphalt, considerable difficulty arises due to hardening of the asphalt 'throughout the body of bristles of the brush,
it being very difficult to remove the hardened asphalt in order to clean the brush. Still another object of the presentl invention is to facilitate the cleaning of a spreader used withlasphalt and similar road surfacing materia s. l
The road surfacing liquid is ordinarily distributed by means of spraying equipment mounted on a. truck chassis and including a large tank and an appropriate system of spray 'nozzles arranged at the rear end of the truck chassis.v It is desirable that the spreading of thc liquid takev place immediately after it has been sprayed, in order to prevent premature cooling of the same. Y Itis also desirable that the spreader be propelled by the distributing truck for simplicity and economy, and for the further reason that any additional vehicle employed especially for the spreader Would have to run upon the freshly deposited bitumen, Whereas the Wheels of the distributor truck run upon the velements and their relation one to the other as icrein after are moreparticularly described in the Vspeciicatiim and sought to be defined in theclaims. The specification is accompanied by drawing'in which:
Fig. 1 is a rear elevation of a spreader embodying features of my invention;
Fig. Q'is a section taken in the plane of the line 2--2 in Fig. 1; and l Fig. 3 illustrates a'modification.
Referring to the drawing, the spreader of my invention comprises a relatively thick pad l2 of rubber, felt, or asbestos, or the like, which is held in a substantially upright position. This pad is made sutliciently thick to be relativelyl stiff and to be able to transmit the desired vertical pressure forforcing the fluid into the cracks and interstices of the road, but hassuflicient give to adjust itself to the surface irregularitiesof the pavement as it sv'eeps over the same, so as to carry excessive Huid along with it. The action is effectively like Ithat of a squeegee, althouglnvofy course, greatly magnified in dimension.
Thepad 12 isrigidly held alonfY its upper edge in a channeled frame 14 mounted on a rod 16 Which is verticallyl reciprocable in bearings 18 and Q0, bolted to a transverse channel member 22. Ahelical spring 24 surrounds the rod 1G and provides a downward pressure on the frame 14: and pad 12 which serves to effectively preventtlie accumulation *of excessrasph alt, and which at the same time insures deep penetration of the asphalt into the road surface. The frame 14 is'lrirefera-bly mounted on the rod or vpost 16 through a .pivotal connection Q6 `which permits rthe frame and pad to tilt 'or oscillate to an inclined position so that it ivill more readily accommodate irregularities inthe configuration of the road, and more especially so as to enable accomn'iodati'on` of the crown of the road Aand to provide effective operation even at the ec ge portions of a crowned road. The rod or post 1G is preferably made square in cross section` or otherwise altered in configuration and mates with a corresponding aperture in thebearings 18 and 20 in order to prevent rotation of the pad 12 about the post 16 as an axis.
In order to accommodatefirregulartics in the pavement and particularly the crown thereof, I prefer to subdivide the spreader so as to include aplurality of spreader mem bers arranged substantially end to end. ln the present case a spreader member is provided including a pad 12', held in a frame 14 pivoted at 26 to a post 16 reciprocable in bearings 18 and 20, all constructed exactly like the spreader member previously oescribed. t should be noted that the resulting plurality of spreader members are each independently urged in a substantially vertical direction by separate resilient means 2liand 2541- and are each free for independenttilting or oscillation about the pins 26 and 26. Vvvhile the several spreader members are arranged substantially en l to end, they overlap slightly the adjacent ends, as is indicated at 30, and this overlap is ermitted by reason of a slight staggering of the positions of the spreader' mem cers, as best indicated in Fig. 2. rlhis desired stagger is obtained by ofisetting each of the plates Q8 and 28 with respect to the posts 16 and 16. The resulting overlapping of the ends of the spreaders prevents escape of material crebetween and avoids theproduction of stre .ks or unfinished portions between the pads of the individual spreader members.
F or reasons previously set forth, it is preferred to so design the spreader that it may be mounted as an attachment on any of the stand ard or conventional types of truck chas-- sis us d for carrying the spraying apparatus which distributes the road surfacing iiuid.
Such distributingy truclrs almost invariably have a chassis which includes a pair of side chimnels such as the channels 32 and 311-. The spraying apparatus includes a tank 36 mounted on the truck chassis and kept under pressure in order to facilitate the desired discharge of relatively heavy road surfacing fluid. The fluid is fed through pipes 38 and l0 to tubes l2 and al, each provided with a series of nozzles or oi tlets 46.
ln accordance with the present invention the spreader is attached to the channels 32 and 3l of the truck chassis directly behind the distributing apparatus. 'In the present case this is accomplished simply by bolting the channel 22 to the rearward ends of the channels 32 and 34 by means of pairs of bolts or shackles 50 which encompass both the truck channels and the channel 22 of the spreader apparatus.
ln Fig. 3 aslightly modiiied form of distributor member is shown, in which the frame 54 is carried upon a pair of upright rods or posts 55 and 58 reciprocable in bearings 60 `and A62 andresilientlv urged downward by springs Ga and SS.

' ward.
It should be understood that in either modiiication suitable means may be, and preferably are, provided for permitting the distributor members to be raised when the truck is not being used on the road to be repaired. This may consist of appropriate lever mechanism for drawing the distributor members upward against the pressure of the helical springs, or it may consist of any desired type of mechanism for swinging the entire spreadl er mechanism upwardly behind the vehicle. In the present case an exceedingly simple device is illustrated, comprising merely holes 72 and 72 in the posts 16 and 16 respectively, and a pair of pins, not shown, which may be inserted in the holes. The spreader members arelifted upwardly, one at a time, against the spring pressure until the apertures come vabove the tops of the bearings `20and 20', at which time the pins are inserted in the apertures and hold the spreader members in their elevated position by pressing against the upper faces of the bearings 2O and 20.
The manner in which the spreader equipment of my invention may be constructed and applied to a distributor vehicle, will, itis thought, be understood from the foregoing d-escription thereof. The many advantages of the present spreader will be evident from the construction and may be summarized as follows. The pads or squeegee portions 12 and 12 of the spreader produce a pressing action and a sweeping action. The pressing action consists of pressure transmitted in a substantially vertical direction which produces an excellent penetration of the surfacing liqu-id into the small cracks, voids, and interstices of the pavement. The liquid is left in any such spaces, and is not carried out of the same as is the case with a brush or broom. The sweeping action carries any eX- cess of liquid before the spreader and prevents the accumulation of puddles in waves and holes in the pavement. The success of the squeegee portions depends upon their having suflcient stiffness to transmit a vertical pressure, and yet having sufficient yieldability or give to adjust themselves to all of the surface irregularities of the pavement except the small crevices and voids. For this result, the squeegee portions are preferably made straight or flat or plane in the manner shown, for such a construction readily permits the lower edges to yield by bending back- The pressure applied remains relatively constant and is effective immediately after the distribution of the liquid and while the same is still in a fluid and readily worl able condition. Irregularities in the road surface are accommodated by subdividing the spreader into a plurality of spreaders, each of which is independently resiliently urged into direct Contact with the road surface. These spreaders overlap to prev-ent the escape of liquid therebetween. The spreaders iii) are pivotally mounted sot'hat they may tilt in order to accommodate irregularities located at one side or the other ofthe spreader member, and so as to accommodatev definite changes in level such as are caused by the crown of the road. The squeegee portions of the spreader are relatively long in lifeand take considerable wear, first because the road surfacing liquid itself tends to protect them, and secondly because wear at the'lower edges thereof is taken upby the resilient mounting, until they have become almost completely worn off. When thebitumen solidifies and hardens on the spreader membersbetween the periods of use, it may-be removed with but slight difficulty relative to the trouble occasioned by the same diiculty in connection with Abrushes and brooms or the like.V The spreader member may be manufactured as an accessory which is readily attached to distributor wagons or trucks; and in the latter case the attachment is facilitated bythe con Ventional projection of the side channels of the truck chassis at the rear-end thereof.'
