ASPHALT 'SPREADER Application led March 14, 1927. Serial No. 175,338.

My invention relates to .a machine for spreading asphalt or the like materlalon roadways in a condition ready for the rolling operation and it is an object of the invention to provide a machine of this character which will eliminate a large amount of manual labor in the laying of roadways and by means of which such operation may be more quickly, easily and more efliciently accomplished at a reduced cost, all. as will be hereinafter more particularly described and claimed. .y

Referring to the accompanying drawings, which are made a art hereof and on which similar reference c aracters indicate similar parts,

Figure 1 is a diagrammatic view illustrating one application of my invention,

Figure 2, a side elevation, Figure 3, a vertical longitudinal section, Figure 4, a top plan View, Figure 5, a diagrammatic front elevation, Figure 6, a fragmentary rear elevation, and

Figure 7 a diagrammatic plan View.

In the drawings reference character 10 in! dicates the flanged wheels supported upon steel rails 11 at each side ofthe roadway. The flanged wheels on each rail are carried by trucks which comprise inner and

outer side lates

12 and 13 connectedl by spacing v mem ers 14. The-trucks-are connected by means of braces 15 vwhich extend across the roadway and upon which are supported the various blades and the-like of the machine. The machine is designedto scrape over the roadway in order to properly level and form the same into shape and for this purpose I provide a cutting blade or scraper 16 secured to the lower portion of a plate 17 which extends transversely across the machine, such plate being-adjustably mountedat its ends between angle ironsl 18 and by means of screws Y 19 can be raised or lowered as desired.

trucks or the like the ready mixed asphalt or other preparation of which the roadway is to be formed and such preparation is preferably dumped in small spaced piles on such pan or apron and is raked therefrom onto thesubgrade or surface of the roadway prepared by the cutting bladeor scraper 16. On account of the spreader or apron 21 having its lower portion in Contact with the surface :of the roadway prepared by the cutting blade 16 such spreader or apron` will form a drag and will serve to smooth down vthe sub-grade or surface of the roadway so thatrolling is unnecessary. Also by depositing the material on the spreader or apron the standard specifications for road building which require the y :asphalt composition or the like be not dumped directly on the sub-grade is adequately complied with and the weight of the deposited material serves to hold Adown the apron.

Rearwardly of the apron 21 is supported, in a manner similar to the blade 16, an adjustably mounted blade or rake 22 which is adapted to strike olf, screed or comb the road building composition. Also adjacent the rear of the machine is a similar adjustablymounted blade or gage 23 for determining the final thickness of the spread-material. f y

A longitudinally disposed platform 24 may be provided-at each side of the machine across which is adapted to be suspended one or more platforms 25 for supporting laborers for raking the material from the apron onto the roadway.

At the rear end of the machine in spaced relation to the blade 23 is across member 26 connected by braces 27 with a bar 28 both of which members 26 and 27 are vertically'adjustable ina manner similar to the blade 16.

The machine may be provided with its own power plant by means of which it may be propelled or vit may be pulled by a tractor'or power unit ahead of the same, as shown. When the machine is pulled by a tractor or the like I preferably provide a flexible bridle 29 which comprises a pair of straps which have their front y ends connected and have their rear ends attached to the trucks at the sides of the roadway, such flexible straps are adapted to lie flat on the ground to permit trucks or other vehicles to back in and discharge their loads without interference.

In lieu of ythe flanged wheels, which are supported on the spaced rails at each side of the roadwa obviously, other Wheels may be provided w lich operate directly on 'the road DIV)
