WILLIAM A. DEAN, OF MIDLAND, TEXAS.

ROAD-MACHINE.

Specification of Letters Patent.

Patented Oct. 24, 1916.

Application filed March 23, 1915. Serial No. 16,425.

To all whom it may concern:

Be it known that I, WILLIAM A. DEAN, a citizen of the United States, residing at Midland, in the county of Midland and State of Texas, have invented certain new and useful Improvements in Road-Machines, of which the following is a specification.

The invention is primarily designed to provide a machine for resurfacing roads or preparing new roads'in the construction of highways for traflic.

The invention provides a machine which may be readily adapted for throwing the earth from the center outward or from the sides of the road inward toward the center depending upon the nature and condition of the roads surface.

The machine is also of such construction as to admit of the scraper being readily raised or lowered, so as to remove high places, or fill in ruts or low places in the surface with the result of leveling the roadway, the machine including drags or shoes for compressing side portions of the roadway which are adapted to sustain the wear and action of the wheel of vehicles and other carriers traveling thereover.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly claimed.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention as claimed may be resorted to when desired.

Referring to the drawings,Figure 1 is a top plan view of a road machine embodying the invention. Fig. 2 is a side elevation. Fig. 3 is a vertical central longitudinal section on the line 33 of Fig. 1. Fig. 4 is a detail perspective view of the mountings for one of the scraper blades. Fig. 5 is a top plan view of the front portion of the machine having the scraper blades interchanged so as to throw the earth from the sides of the road inward toward the center.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawmgs by the same reference characters.

The machine embodies a truck and a main frame, the latter being provided with the scraper blades and the drags or shoes and being adjustable to admit of the scraper blades being elevated or lowered according to the result to be attained.

The truck comprises an axle 1, ground wheels 2, and a bolster 3, the latter having the axle l clipped or otherwise secured thereto, such bolster being thin and wide and arranged with its width in a vertical position so as to cooperate with the guides l to hold the main frame and truck in a given relative position. The truck forms a convenient wheel support for sustaining the major part of the weight and enabling the machine to be propelled or drawn over the road or field with the expenditure of a minimum amount of force. A standard 5 is secured at its lower end to the bolster 3 and projects vertically therefrom. The standard 5 may be of any substantial construction and is centrally disposed with reference to the truck and is provided upon its front side with a wear plate 6. The upper portion of the standard 5 is bifurcated and receives a lever 7 which is longitudinally disposed and vertically adjustable. The standard is formed with a plurality of openings 8 and is adapted to receive a pin 9 upon which the lever is mounted. A toothed bar 10 is secured to the upper side of the lever 7 in the rear of the standard 5 and is adapted to cooperate with a bail 11 to hold the lever in the desired adjusted position. A chain 12 or like connection is attached to the front end of the lever 7 and is attached at its lower end to the main frame. The chain or analogous connection 12 is attached at its ends to opposite sides of the main frame and intermediate of its ends is adjustably con nected with the lever 7. A bail 11 is pivotally connected at its lower end to the truck and its upper end has adjustable connection with the lever 7.

The main frame comprises similar or like side members and a platform, the latter be ing mounted upon cross pieces 13 which are attached at their opposite ends to the side members, The platform is indicated at 14; and may be of any construction and preferv occasion may require.

ably comprises a plurality of boards or planks placed upon the cross pieces 13 and attached thereto in any manner. The platform 14 receives the driver or operator and may be utilized as a support for additional weight should it be necessary to increase the pressure of the drags or shoes so as to properly compress the surface of the road-way. Each ofthe side members of the main frame comprises a long beam 15 and short beams 16 and 17 the several beams being connected in any substantial way- The beams 17 are located rearmost and are provided at their rear ends with drags or shoes 18 which are constructed to trail upon the side portions of the road-Way'and compress the same sufficiently to insure the formation of a serviceable surface. The beams 16 serve to connect the drag beams 17 with the main beams 15. This construction also provides for lengthening the side beams or members as The guides 41 extend vertically and consist of loops which receive the axle and bolster of the truck, the lower ends of the guides being secured in any substantial way to the side members of the main frame. Cross braces 19 connect the forward ends of the main beams 15 and serve to stiffen and" strengthen'the same. A brace 20 is secured at its lower end to the forward cross bar 13 and inclines upwardly and rearwardly' and is provided at its upper rear end with a roller 21 which bears against the wear plate 6 and is adapted to travel thereon in the vertical adjustments of the main frame. A post 22 secured at its lower end to the point of crossing of the braces 19 has i its upper end secured to the brace 20, thereby forming a stay therefor.

A block 23 is adapted to be secured to the front en d of each side member or main beam 15 and is provided at its front end with a scraper blade 2 e. The scraper blades 24:

incline transversely and may be arranged to move the earth from the center of the road outward toward the sides thereof, as indieated in Fig. 1,'or from the sides of the road toward the center, as indicated in Fig. 5.

The scraper blades 24 are attached to the front ends of the blocks 23 and such blocks may be shifted from one side of the machine to the other when adapting the machine to throw the earth outward or inward. U- shaped

straps

25 and 26 are secured at their closed ends to. the scraper blades and their furcate ends embrace opposite sides of the v blocks and are bolted or otherwise secured thereto. The U-shaped strap or fastening 26 is disposed in a vertical plane and embraces the upper and lower sides of the block 23. The 'U-shaped strap or fastening 25 is disposed in a horizontal plane and its furcate ends embrace opposite edges of the block. The

fastenings

25 and 26 are secured to the scraper blades 24; in any manner and are detachably connected with the blocks to admit of the blades being removed or replaced.

' The machine is adapted more particularly for leveling road-ways by removing high places and filling low places, such as ruts and depressions. The machine is equally well adapted for preparing new roads across fields and other places.

In the operation of the machine, the same is propelled over the road or field and the main frame is adjusted to bring the scraper blades to the required elevation and said scraper blades are adjusted to move the earth outward or inward in the manner hereinbefore stated. The shoes or drags 18 trail upon the surface in the track of the scraper blades so as to compress the earth and prepare a surface sufficiently dense to resist the cutting and abrasive action of vehicle wheels. The. operator or driver stands upon the platform 14 so as to control the lever 10 whereby the front portion of the main frame may be raised or lowered to bring the scraper blades to the desired position for action on the surface to the best possible advantage. The rearward thrust upon the main frame is sustained by the guides 4L and the brace 20. The draft may be applied directly to the truck or to the main frame and any suitable means may be provided for this purpose.

Having thus described the invention, what is claimed as new is 1. In an apparatus of the class described, a rigid frame having scrapers at one end and drag shoes at the other end, a truck inc1uding bearing wheels, means for supporting said frame for forward movement with said truck, and means carried by said truck for adjusting the said frame vertically.
