ROAD-MARKING APPARATUS AND VEHICLE Filed 001;. 20, 1959 United States Patent Claims priority, application Italy (lot. 21, 1958 Claims. (Cl. 156-526) This invention relates to a road-marking vehicle designed to be driven or towed on road surfaces for mechanioally laying on and adhesively connecting to said surface a road-marking known material in strip form, as an elasto-plastic compound material, a rubbery fiber reinforced or not reinforced compound material in strip form possessing adhesive character or designed to be provided with an adhesive agent prior to its being laid on and engaged with the road surface.

More particularly, it is an object of this invention to provide a new and improved vehicle as above, designed for mechanically laying down and adhesively applying on road surfaces a continuous or interrupted strip of said road-marking material or materials, and the like, namely for providing the said road surface with centre-lines or with track-dividing lines or other trafiic signs on road surfaces, prevailingly but not exclusively located lengthwise of the road, the said laying and application of strip material being carried on by the hereinafter described assemblies, devices and means of the vehicle of the invention as the latter is caused to travel on the road surface along a given path.

A more specific object of this invention is to provide an improved road-marking strip material laying mechanism including strip material guidingly feeding and laying down rotary means for continuously or interruptedly putting the said strip material in intimate and adhesive contact and engagement with the said road surface.

The present invention further contemplates, in a preferred form of embodiment thereof, the mechanical laying on and adhesive attachment to the said road surface of spaced lengths of road-marking strip material of the type considered, and the provision of mechanisms, devices and means adapted to overcome the various problems involved in such road marking operation, in particular for ensuring the evenly spaced feeding of lengths of said material to the said laying down device and the full and sure attachment of said lengths in particular, of the re spective leading end portions to the road surface.

It is vide, in a strip material laying down vehicle for the above operation, means for supplying a continuous strip of said material, cutter means for cross-cutting the same into successive lengths, holding means for supporting the leading end of the strip coming forth from the supply means upon each cutting step, feeding and guide means adapted for successively engaging said leading ends and the respective lengths of strip material and guidingly to put said ends and lengths in intimate contact with said road surface, and pressing means adapted for downwardly urging the said leading ends on the road surface to which said ends have previously been put in contacting relationship, for ensuring the full and throughout permanent 'adherence of the strip material, in particular at its end portions, with said surface.

These and other objects and advantages of the invention are in part obvious and in part will be made apparent as this invention proceeds, and the features which are believed to be new and characteristic of the invention are in particular set forth in the appended claims. The invention itself, however, both as to its construction and to its mode of operation will be best understood from the therefore a further object of this invention to profollowing detailed description of preferred forms of em- I bodiment thereof, when taken in conjunction with the ac- 3,957,838 Patented Nov. 7, 1961 2 companying drawings, forming an essential component of this disclosure, and wherein:

FIGURE 1 is a vertical longitudinal elevational view of the assembly including the combined strip material feeding, laying down and pressing devices, means and elements in continuous strip applying condition of operation;

FIGURE 2 illustrates in similar view the feeding means of said assembly during the engagement step of the leading end of strip material, upon cutting a length therefrom, while performing a road-marking operation by successively laying down spaced lengths of strip material;

FIGURE 3 is a diagrammatical side elevational view of the general arrangement of the various essential means in a vehicle of the invention, including a modified assembly; and

FIGURE 4 is a somewhat simplified view of an exemplificative mechanism adapted for phasedly driving the various co-operating cutter, holding and feeding devices of the said assembly shown in either the preceding FIGS. 1 and 2 or FIG. 3.

Like reference numerals refer to like parts and components throughout the several figures of the drawing, mere structural details and various vehicle components having been omitted where they are appertaining to the known art. Referring first to FIGS. 1 and 2 inclusive:

In the form of embodiment shown, the illustrated assembly is intended for laying down on and adhesiveiy connecting to a road surface, generally indicated at 10, a strip material indicated at 11a as coming forth from a suitable supply (not shown) and at 11b as being already laid down and adhesively connected on and to the said road surface.

The said supply may consist of a roll of continuous strip material, carried by the same vehicle or by another vehicle towed or driven behind the material laying vehicle. Motor driven strip material feeding means may be provided for feeding the material into the apparatuses hereinafter described, and clutch and/or brake means being provided for ensuring the correct continuous and/ or interrupted feeding; such means may in their turn be provided with self-acting control means, responsive to the tension to which the material at 11a is subject, for example, by electric signalling from a potentiometer 12 (FIG. 4) controlled by a known tension-metering device generally indicated at 13.

The material laying assembly of FIG. 1 is supposed to be supported by the frame structure (as indicated at 14 in FIG. 3) of a road vehicle (not shown) adapted to travel in direction A along a given path on the road surface to be marked. Such vehicle will obviously include steering means and other facilities, such as optical aiming means and the like, for ensuring the correct motion of said vehicle so that the strip material laying devices carried thereby will exactly track the path to be marked.

The assembly of FIG. 1 includes a strip material pressing structure including a frame 15 rotatabiy supporting rollers 16 and 17 at its fore and respectively rear end portions, whereby a substantial space is defined therebetween, wherein a corresponding length of strip material may be subject to a pressure for ensuring the full engagement of the strip material, in particular, the leading edges of lengths of said material, upon first contact thereof with the road surface, as occurring at 18. The provision of pressing means capable of effective pressing down of such leading ends had been proved as essential for actual marking of road surfaces with interrupted strips, i.e. with spacedly laid down lengths of strip material.

Obviously such pressing down might be obtained by making use of diifering but operatively equivalent means, as by means of relatively movable roller means, for example, or by making use of temporary clamping means 3 for the leading end portions co-operating with roller or slide pressing means, and the like, actuating a pressing down surface, or a plurality of pressing down surfaces or locations.

In the form of embodiment of FIG. 1 the said pressing down surface consists of the outer face of an endless belt member 19 having a lower run 19a supported about said rollers 16 and 17 and an upper run supported about

rollers

20 and 21.

The required downward pressure exerted by the embodiment of the pressing down surface of FIG. 1 may be attained by the provision of evenly spaced idler rollers '63 supported above said run portion at 19a and downwardl urged as by spring means 64. The whole of structure '15 might be articulately and/ or downward urgingly connected to the vehicles frame structure (not shown). For example, the modified form of embodiment shown in FIG. 3, wherein the said structure is generally indicated at 115, is provided with downwardly urging spring means 65.

In the example given, the strip material is guidedly caused to travel along and with the said belt member 19, in particular in contact relationship with the downwardly directed run 1% thereof, by ancillary guiding means consis-ting, for example, of another belt-like member 22 circuitably supported about a plurality of rollers 23 to 26 inclusive and having a run portion at 22b in adjacent relationship with said run portion 19b for guidingly carrying the said strip material therebetween. The preceding run portion 22a of said ancillary belt member 22 is arranged in juxtaposed relationship with a run portion 27a of a further ancillary belt member 27, circuited about rollers 28 and 2?.

As comparatively illustrated in FIGS. 1 and '2, the said

rollers

23 and 28 are movably supported in the assem'blys frame (not shown) for reciprocation in direction 13 and respectively B to set the said belt members runs 22a and 27a in the open position of FIG. 2, wherein the said runs actuate an inlet mouth adapted for receiving the leading end 110 of the strip material upon cross-cutting thereof, and then in direction opposite to B and B" for closing said inlet (FIG. 1) and clampingly engaging therebetwee'n the said material for feeding same towards position 18 in contact with the road surface 10.

The cutting operation is cyclically performed by a cutting device generally indicated at 39in FIGS. 1, 2 and 4, and this cutting device is preferably provided with opposed reciprocable cutters or knives 30 and 31 or other known means. Said cutting device is displaceably supported at its slide structure 33, integral with the cutters supporting and guide means at 32, as along rails 34 for back and forth reciprocation in directions A and A".

The leading end 11c of the strip material, resulting upon cross-cutting thereof, is in its turn temporarily supported and fed in the said inlet mouth, in spaced relationship with respect to the previously fed length of strip material by holding and intermittent feeding means generally indicated at 40 and preferably including elongated pincers or clamping means 35 and 36 articulated on a structure 37 displaceably supported at 38 on rail means, as the said rail means 34 supporting the cutting device 39 (FIG. 1) or different ones (FIG. 4).

The said inlet forming means, cutting means and holding and feeding means are phasedly driven for cyclical operation thereof by suitable mechanisms, of which in FIG. 4 an example is given. According to the form of embodiment of FIG. 4, such mechanism includes a cam group 41 provided with cam grooves to which levers 42, 43 and 44 are responsive, the said cam group being drivingly connected for synchronization to the material carrying belt members, as, for example, by means of bevel gears 45, a transmission chain 46 and further gears 47, the roller 21 circulating the belt members always acting as the belt driving roller.

The said

levers

42, 43 and 44 are drivingly linked, as by means of pitman levers 48 and respectively 49 and 50, to the said inlet mouth forming components and respectively to the cutting device 39 and to the holding and feeding device 40, the phase relationship of the said components and devices respective motions being defined by the shape of the cam means, according to current knowledge. The amplitude of motion of lever 43 may be amplified by a mechanism including a gear pinion 51 in mesh both with a standing rack 66 secured to the assembly frame structure (not shown) and with a rack 67 made integral with the structure 38 of the said holding and intermittently feeding device 40. 1

In FIG. 3 the general and typical arrangement of the several devices which may be included in a vehicle produced and operating according to the invention is diagrammatically shown. In said FIG. 3 is further shown a modified form of embodiment of the assembly hereinbefore described with reference to FIGS. 1 and 2. In such modified form of embodiment, in addition to a somewhat differing construction of assembly 1115 designed for downwardly urging the lower run 11% of belt member, the downwardly moving run 1191) of same member and the ancillary guiding belt member 122 are difleringly arranged for adaptation of an adhesive agent applying device adapted for applying a thin layer or film of adhesive'substance on the strip material being fed towards the'road surface. 7

Such device may consist of a wetting roller .57 fed by means of intermediate rollers with a liquid adhesive substance from a supply at 58, such device being not further described in detail as structurally and operatively corresponding -to known inking or wetting means of current product-ion.

Preferably adhesive agents in rapidly evaporating liquid solvents are made use of for prompt completion of the permanent adhesive engagement of the strip material on the road surface 10. The fast evaporation or vanishing of solvent may be further improved by proper heating of the adhesive wetted or coated surface strip material, as by means of an heating unit'at 59.

The full adherence of the strip material applied to the road surface at 10 may be further improved by wetting said surface too with an adhesive agent, which may be spread on said surface, in front of the position of first contact of the said strip material on said surface, as by means of spraying means at 60, and the prompt evaporation of the solvent or the setting of the agent may be improved by a blast of hot air or other gaseous heatvehicle as from jets 61.

Properly directed air streams, produced say by said jets 61, may beadvantageously made use of for ensuring the proper advancement of the strip material, and, in particular of the leading ends of the successively fed lengths of material to be sp'acedly laid on the road surface, beneath the material laying and pressing rolling means. Such utilization of air or gaseous streams and the means provided for producing same will be therefore considered as appertaining to the ancillary devices and means provided for guidin'gly feeding the said strip material either in its continuous or-in its interrupted condition towards the position of first contact and engagement beneath the laying down rolling means, and therefore such air or gas jet means will be considered as included in the definition of said ancillary material guide means in the appended claims.

The above described several feeding, laying down and pressing devices and means are advantageously combined, in a vehicle or in a group of vehicles according to the invention, with suitable road surface preparing means, designed to operate on said surface as the said vehicle travels in direction A.

Such latter means may include, for example, mechanically driven

rotary brushes

52 and 53, one or more rollers 54 of sponge material for suction of atleast the prevailing-part of water or ther liquid which may exist on the road surface, and burners 56 or other source of heat, or jets of overheated air or of other gases for burning away or otherwise eliminating any residual moisture. Such heat ing means may be further advantageously made use of for suitable pre-heating of the road surface to improve the adhesiveness of the strip material thereon.

While the invention has been described and shown but in few forms of embodiment thereof, it is obvious that the invention itself is not limited to the very details shown, and that several structural modifications and variations might be made thereto, according to the art.

It is moreover believed to be evident that the present invention includes a plurality of advantageous features, and it will be understood that each of the new features described and any combination thereof may find useful application in other constructions of road-marking strip material laying down apparatuses differing from the ones described.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of this invention and, therefore such adaptations should and are intended to be com rehended within the spirit, meaning and range of equivalence of the invention, as defined in and by the appended claims.
