Application October 26, 1935, Serial No. 46,901 5 Claims. (Cl. 94-45) This invention relates to improvements in ma chine for and method of producing tra?ic lines in concrete and particularly to the means and method wherein said tra?ic lines are inlaid in 5i. the plastic concrete roadbed under construction. The principal object of the present invention is the production of a traffic marking strip in the body of a highway construction while the con crete is green and plastic, thus insuring proper 10- bonding between the road construction material and the marking strip. Another object of this invention is the method of inlaying a strip of plastic material in the green material of a roadway so that upon hard 15? ening, the strip becomes an‘integral part of the roadway. ' ' A further object of the invention is the pro— vision of a machine that is adjustable to roads of different surface contours and widths. Many other objects will appear during the course of the speci?cation, wherein reference will be had to the drawings, in which: Figure l is a plan view of a machine for in stalling traffic lines in a concrete roadway em 25 bodying this invention. Fig. 2 is a vertical section, taken on line II—II of Fig. 1, showing the machine in operative posi tion on the roadway.

Fig. 7 is a vertical, cross sectional view taken on line VII-VII of Fig. 6. Fig. 8 is a vertical, cross sectional view taken on line V1II—VIII of Fig. 6. Fig. 9 is a cross sectional view of the strip or ?ller embedded in the plastic concrete oi the roadway to produce the groove. Fig. 10 is a view similar to that shown in Fig. 45 9, with the forming strip removed. Fig. 11 shows a cross sectional view of the sled, with the runners engaging the opposite side walls of the groove. ‘ Fig. 12 is a section through the rear portion 5 O of the sled in the operative position, with the groove ?lled with a plastic cement ?ller. Fig. 13 is a vView similar to that shown in Fig. 12, with the sled moved out of engagement 55 therewith. Fig. 14 shows the cross sectional view of the marking strip in its complete form, and, Fig. 15 is a fragmentary, sectional view of the hollow axle. Throughout the several views like reference 5 characters designate similar parts and the nu meral 2|] indicates a carriage or bridge member, mounted on wheels 22 and 24, which in turn are adapted to rest on the rails or side forms 25 that serve to maintain the road material 28 10 within the limits of the roadbed. Wheels 22 are provided with double ?anges 20 that serve to maintain them in operative position on the rail; also wheels 24 are provided with flanges 32. The body of carriage 20 consists of 15 a fabricated framework, having end members 34 and 33 secured together by means of cross members 38. Each set of wheels 22 and 24 are in axial align ment and are mounted respectively on hollow 20 axle 4i] and squared axle 42. These axles are rotatably mounted in bearings M carried by mem bers, 36 and 34 and squared axle 42 is slidably mounted in the squared socket 46 positioned in 25 hollow axle 46. The following driving mechanism is provided for moving the entire carriage lengthwise of the roadway and consists of a sprocket wheel 48, rig idly mounted on axle 132, a transverse shaft 59 mounted in bearings 52, which in turn are carried 30 by platform 51%. Rigidly mounted on shaft 50 is a small ‘sprocket wheel 56 which is interconnected with sprocket wheel 48 by sprocket chain 58. The opposite end of shaft 50 carries a sprocket wheel 56 through the intermediacy of chain 62. 35 Through the intermediacy of chain 62 sprocket 60 is in operative relation with sprocket 64. Sprocket 64 is mounted on a shaft 66, rotatably carried by bracket 68, which is adapted to be rotated manually by means of crank arm “Hi, 40 having a hand hold 12. This driving mechanism is so geared that great leverage is obtained for driving the carriage in either direction. The mechanism for laying the marking strip of concrete consists of a sled member '54, hav- 45 ing a body portion 16 and downwardly extend ing runners 78. The lower portion of the body of the sled is of planar form and is adapted to rest on the surface of the roadbed with the down wardly extending runners l8 engaging the side 50 walls 8%} of the groove 82. A vertically extend ing wall 84, spaced-apart from the opposite run ners, together with an U-shaped cross member 86, serves to form a hopper 88 which opens into groove 82 when the sled is in the opera- 55 2’ ' ’ 2,125,254 tive position. The rear end of the sled is of a continuous planar form in cross section, as shown in Fig. 8, and serves to form and pack the ma terial into groove 82 as the sled is moved for wardly. Sled ‘I4 is interconnected with carriage 20 for universal adjustment, thereby permitting it to be adjusted to the contour of the road surface, regardless of vthe cross sectional form of the surface of the road. 10 Mounted on cross bars 38 are transversely dis posedjparaiiel tubes 99, on which are adjustably mounted brackets 92. These brackets are pro-_ vided with openings 94 and serve as bearings for vertically disposed adjusting rods 95 to prevent 15 relative longitudinal movement of rods 94 in. brackets 92. Collars 98 are secured to rod 95 at opposite sides of 92, thereby allowing rotary is now deposited between runners ‘I8 into groove 82. It is then leveled and packed by surface I24 of sled ‘I4. As the sled moves forwardly away from the deposited material, it appears as shown in Fig. 13 with slight grooves at its opposite edges. It has been found best to slightly trowel the inserted strip and the adjacent road material after the machine has completed its work. For convenience of the, workmen in operating the de vice, a platform H26, supported at its opposite 10 ends on members 35 and 34, is provided. This platform may be moved transversely of the ma chine to position it relative to the sled ‘I4. > Other similar platforms might be added if needed. The carriage might be drawn by road surfac 15 ing machine thus eliminating the necessity of an operator, or it might be provided with a motor movement of 96. Lower end of 99 is threaded as driving device that could drive it at any desired at I09 and is adjustably mounted in the threaded rate of speed. opening I02 of arm I04. This arm I94 is pivoted ' It is apparent that the machine shown and de at I06 to cross bar I98 secured to sled ‘I4 adjacent scribed is adapted to lay a tra?ic line of plastic 20 its front portion. This construction permits of material in a green concrete roadbed which will transverse oscillation of. arm I94 relative to the have a secure bonding therewith. Furthermore, sled. the material of the dividing strip will be so posi 25. This sled supporting mechanism is duplicated tioned and separated from the side walls of the 25 at the two sides of the front portion of the sled. groove in the concrete during the formation. of At the rear portion of the sled similar parts as the strip that joining lines of the two materials just described are provided for mounting the sled will be de?nite and straight and without the soi in proper position relative to the carriage and the roadbed. The arms I94 are pivotally (usual ragged edge effect. Also with this device mounted to ears lill which are formed integral the desired effect. with the body of the sled. For propelling the sled during the operation of the machine, stand ards H2 extend upwardly from the body of the 35 sled in the path of travel the end member 36, which serves to propel the sled forwardly with out exerting too much strain on the adjusting parts. Furthermore, these standards H2 are positioned just to the rear of the tube 90, thus making it possible to move the sled backwardly forcing 92 against standards H2. It will be observed that the U-shaped cross member 86 is slightly rounded as at H4 so as to ride over the material and cause a proper 45 packing of they same. When this marking device is used on a crowned road which consists primarily of two planar road surfaces angled relative to each other, it is ap parent that by the operation of hand wheels H6 mounted on shafts 96 the sled 14 may be tilted to either side to conform to the surface of the strip into which the marking strip is being em bedded. The method of forming or constructing this 55 marking strip is best shown in Figs. 4, 9, DD, 11, 12, 13, 14 and 15. Referring to Fig. 4, it will be noted that an insert strip or ?ller H8 is em many different materials might be used to obtain 30 I , Having thus described the invention, what is claimed as new and desired to bersecured by Letters Patent is: , 1.
