MAKING or RoADwAYs.
Specification of Letters Patent.
Patented Sept. 3, 1918.
Application filed April 24, 1917. Serial No. 164,087.
To all whom it may concern:
Be it known that I, J AMES CHAPMAN, citizen of Great Britain, and resident of St. Annes St. J amess Road, Forfar, in the county of Forfar, Scotland, have invented certain new and useful Improvements in or Relating to the Making of Roadways, of which the following is a specification.
This invention relates to the making of roadways for vehiculartraflic and has for its object to provide a roadway which will minimize the wear and tear of the roads and vehicles using same, prevent dust and also reduce the amount of power required for drawing or driving vehicles.
According to this invention I insert in the road two or more parallel strips of concrete, asphalt, artificial stone or similar material laid 'in sections previously formed, or molded in sz'tu and which may be used alone or which may have met-a1 reinforcement embedded in it, the parallel strips being of such width as to accommodate wheels of varying distances apart.
The following description and accompanying drawings show manners of carrying out the invention.
Referring to the drawings Figure I is a transverse section of a roadway in which one pair of surfaces has been laid.
Fig. II is a plan of Fig. I.
Fig. III is a transverse section of a roadway in which three surfaces have been laid for broad and narrow gage trafiic.
Fig. IV is a plan of Fig. III.
Fig. V is a transverse sectionof a roadway in which two pairs of surfaces have been laid.
Fig. V1 is a plan of Fig. V.
Figs. VII, VIII, IX and X are sectional views showing modified forms of surfaces embodying my invention.
Fig. XI is a sectional view showing further modified form of surfaces and means for connecting the surfaces.
In the arrangement of Figs. I and II two trenches are prepared in the road a of suitable depth, according to the nature of the soil and traffic requirements, and in these trenches are formed continuous lines of reinforced concrete 6 and 0, parallel with II a single pair of bearing strips is shown, for use of traflic in either direction if the traffic on the road is not very great.
In the modification shown in Figs. III and IV three surfaces Z, c and are employed to accommodate broad or narrow gaged traffic, the surfaces d and 6 being adapted to accommodate the broad or ordinary traliic, and the surfaces 6 and f the narrow gage traflic. The surface 6 being common to both broad and narrow gage traific.
Figs. V and VI show two pairs of surfaces, g, h, '11, j, one pair being for use of traflic in one direction and one pair for traffic in the other direction. Such an arrangement would probably be found suitable for main high roads where the traffic is con siderable and travels quickly.
As shown in Fig. VII, the upper surface of the strip is curved in the form of an are so that the upper ed es of the strip are disposed below the surface of the roadway thereby protecting the edges of the strip from the action of vehicle wheels when they are passing onto and off of the strip.
In Fig. VIII, the edges of the strip are also disposed below the surface of the roadway. However in this embodiment the edges are rounded as shown. In Fig. IX, the upper edges of the strip are beveled, this construction also preventing vehicle wheels moving transversely of the strip, from damaging the edges of the strip.
Referring now to Fig. X, I have here shown a strip of rectangular formation in cross section which is provided with a metal bar m. The upper edge of the bar m terminates flush with the upper surface of the strip, so thatit forms one edge of the strip and thus prevents wear and damage to the strip by the wheels of the vehicle going on and OK the strip.
In Fig. XI, I have shown a pair of strips formed on their under sides with depending tapered spikes p. The spikes p when properly embedded within a road-bed prevent any lateral displacement or circumferential movement of the strips. The strips are connected by means of metal rods 8, the opposite ends of such rods being bent at an angle and embedded within the strips, as shown. Bymeans of the rod 8, relative movement of the strips is prevented so that they are maintained in proper spaced relation at all times. It will be noted that by virtue of the fact that the ends of the rod are embedded Within the strips, therod is utilized as a reinforcement for the strips.
I cla11n: 1. A roadway conslstlng of parallel continuousstrips ofmaterial Which are capable of being molded in sit u in trenches formed in sald roadway, the upper surfaces of said strips being level with the surface of the roadway and of a widthsuificient to accom- 1 of being molded in situ in trenches formed in said roadw-vay, the upper surfaces of said strips being level With the surface of the roadway and approximately rectangular in cross-section and of a Width sufficient to accommodate vehicles of varyingwvheel-gage using said strips, and metal reinforcement, embedded in and entirely inclosed by the material of said strips, so that neither air nor moisture can have access tos'aid reinforcement.
