Application ined Decanter 15, 1894. sannita 531.956. (naman.)

To ctZZ whom it may concern:

Be it known that I, HENRY PoUoIInR, a citizen of the United States, residing at Brooklyn, in the county of Jackson and State of Michigan, have invented a new and useful Road- Machine, of which the following is a specification.

My invention has special reference to an improvement in those road-machines wherein two Scrapers or plows are employed and arranged to throw the dirt inward; and the invention consists of certain improvements in the construction of the scrapers and in the mechanism for actuating and operating them, whereby they are made to perform their function with more ease and efficiency than ordinarily, and whereby a machine more desirable in other respects is produced.

In the drawings, Figure 1 represents a perspective view of the complete machine; Fig. 2, a cross-section taken through the beamer bar for supporting the scrapers; Fig. 3, a detail perspective of one of the Scrapers, showing it detached; Fig. 4, a section taken lougitudinally through one of the Scrapers and showing the detail construction thereof; Fig. 5, a longitudinal section of the machine; Fig. 6, a detail perspective of one of the clips for the draft-chains.

The frame of the machine consists of the parallel transverse beams 1 and the diago` nally-extending and longitudinal beams 2, all four being rigidly connected to each other. Secured to the rear beam of the beams 1 and to the rear portions of the beams 2 is the platform 3, which is formed, preferably, of sheet metal, though this may be varied at will. The beams 1 are extended beyond the general width of the machine, and the front beam has the bolster, 4 rigidly secured thereto. Pivoted to the bolster 4, so as to swing thereon, and' lying against its underside is the axle 5, upon which the front carrying-wheels 6 are mounted. By

these means the front of the machine is supported, and the axle 5 has the draft-shaft 7 affixed thereto,.wherebythe team for drawing the machine is connected.

The rear carrying-wheels 8 are mounted upon the spindles 9 of the bent axle 10, which consists of a shaft bent upwardly and forwardly from the spindles 9 and rigidly secured to the rear end of the frame and parallel with the rear beam 1. -U 11 indicates the beam to which the Scrapers or plows are attached, and this is provided with the rigid braced from lateral movement and the proper f position of the Scrapers retained, as will appear more fully hereinafter.

The scrapers or plows are duplicates in construction and consist of the main sections 15, provided with the rigid vertical bolts 16, which arise therefrom and are screw-threaded for the reception of the nuts 1,7. Each of the main portions 15 is formed with the semicircular enlargements 18 in their centers, and these are formed with the similarly-shaped flange 19 at their upper ends, which form a truly circular upper face. This face is ratcheted and adapted to mesh with the corresponding face 20 of the block 21. This block is adapted to lie upon the flange 19 and is provided-with the inwardly-projecting arm 22.

Arms 22 are arranged to lie under the outer ends of the shaft 11 and are formed on their upper faces with the lateral grooves 23, in which said ends lie, whereby the blocks are prevented from moving in the rod or shaft. The bolts 16 of the main sections 15 eX- tend up through the blocks 21 and to a point above the level of the shafts 11, where they are provided with the clamps 24, which iit over the bolts and project forwardly to embrace the shaft 11, whereby the blocks 2l, and consequently the attached parts,are held rigid onthe said shaft. Formed in each end of the main sections 15 of the scrapers are the bolt-holes 25 and 26, the former of which is round in cross-section and provided with a bolt passing into the scraper-blades 27, while the hole 26 is vertically elongated and provided with a second bolt, also passing into the scraper-blades 27. Bythese means the scraperblades are connected to the section 15, vand consequently to the shaft 11, and so -as tolbe capable of adjustment thereon in a vertical line, as will better appear hereinafter.

The scraper-blades 27 consist of steel castings formed with the removable points 28 and IOO mami

with the Inoldboards or inwardly-inclined faces 29, whereby the dirt is scraped or dug up and thrown inwardly from each scraper.

From the aforegoing description it will be seen that the scrapers are mounted so as to be capable of adjustment laterally toward and from each other and axially, so as to determine the angle at which they are to engage the ground.

Secured to the blades 27, at or about their middles, are the hooks 30, to which the draftchains 3l are connected. From the hooks 30 the chains 31 extend forwardly to the clips 32. These clips are two in number, one for each chain, and are each provided with the transverse openings 33, adapted for the reception of the front shaft or beam 1. The connection between these parts is aloose one, and the wedge-keys 34 are provided and passed through the vertical passages 35 of each clip, they being ada ted to bind against the beam 1 and to hold the clips rigid by such operation. The purpose of these devices is to facilitate the easy drawing of the Scrapers through the ground, and in operation the major portion of the draft strain will be placed on the chains 31.

The means for holding the beam 11, and consequentl y the Scrapers, in the proper horizontal position consists of the vertically-movable bars 35, mounted in the keepers 36, aflixed one to each outer side of the beams 2 and just forward of the platform 3.

`37 indicates two horizontally movable wedge-keys, which are one for each of the bars 35, and by which the vertical position of the bars is retained. The bars 35n are each arranged directly over the shaft 11 and have their lower ends formed with the horizontal enlargements or arms 38, which are adapted to engage the shaft 11,and since the bars are held vertically immovable the shaft will be similarly retained. This will result in securing the scrapers incapable of upwardv movement and make them positively engage the ground.

The bars 35 are best constructed of a stout bar of metal, bent double and having its ends at the lower end and spread longitudinally to form the arms 38. This is not, however, essential. Secured to each front side of the platform 3 and rising vertically therefrom are the standards 39, which are two in nurnber and are provided for the fulcrum of the levers 40. The levers 40 are one for each standard 39 and extend longitudinally with the machine, their forward ends being connected to the chains 41, while their rear ends are provided with the spring-arms 42, which bear against the ratcheted standards 43 and operate to press the levers 40 into engagement therewith.

The lower ends of the chains 41 are connected to the eyes 44 of the shaft 11, and these eyes are one for each chain and eqnidistant from each side of the vertical arm or standard 12. By means of these levers the beam and allowed free movement throughout the vertical extent of the standards.

In using my invention for forming or shaping roads the scrapers are adjusted by levers 40, so that they will be at the proper depth, and the bars 35:L moved into engagement with the beam 11 and set in such position by the keys 37. The scrapers are next adjusted to suit the desired incline or disposition of the moldboard and the nuts 17 tightened on bolts 16, so as to clamp the ratcheted faces of the scraper-sections together, whereby they are held at the proper or desired angle. It will also be necessary to adjust the clips 32 so that they will draw evenly on the Scrapers and not tend to throw them out of their adj ustment. This adjustment (that of clips 32) may be readily understood from the description aforegoing. The team for drawing the machine is next started and the Scrapers allowed to engage the ground and perform their function of displacing the dirt from its original position and throwing it inwardly toward the center of the road. By means of the removable point 28 the points may be replaced when broken or worn out.

Having described my invention, what I claim is-- l. In a road machine, the combination with the frame, of a transversely-disposed bar held rigidly against lateral movement and con- ,nected with the frame so as to be vertically adjusted, Scrapers movable upon the trans verse bar, and adjustable draft connections between the front portions of the said scrapers and the front end of the frame, substantially as described for the purpose set forth.

2. In a road machine, the combination with the frame, of a transversely-disposed bar held rigidly against lateral movement and vertically adjustable with reference to the frame, Scrapers having inwardlyextending arms formed with seats on their top sides to receive the transverse bar, and adjustable on the latter, and adjustable draft connections between the front portion of the frame and the front ends of the said Scrapers, substantially as set forth.

3. In a road machine, the combination with the frame having a laterally-extending bar, of a scraper comprising a main portion, a blade having pivotal connection with one end of the main portion., and having connection with the opposite end of the said main portion, and capable of vertical adjustment, a block secured to the transverse barof the frame and movable thereon, and means for connecting the main portion of the scraper to the said block, whereby the blade is adapted rco Y tical opening in the frame, vertically adj ustable bars to engage with the end portions of the said transverse bar, Scrapers adjustable on the transverse bar and adapted to be adj usted laterally and tilted vertically, and draft connections adjustably attaching the front portions of the said Scrapers with the aforesaid lateral extensions, substantially as described for the purpose set forth.

5. A road machine comprising the combination of a frame, a transverse shaft mounted thereon, an arm fixed to and arising vertically from the shaft and passing through an opening in the frame, whereby the shaft is held incapable of lateral movement, a lever fulcrumed to the frame and connected to the shaft by which the shaft may be adjusted vertically, a bar adjustable vertically on the frame and adapted to engage the shaft and prevent upward movement thereof, and a scraper mounted on the shaft and adjustable laterally thereon, substantially as described.

6. A road machine comprising the combination of a frame, a bar mounted thereon, a block secured to the bar and adjustable laterally thereon, and a scraper secured to the block and adjustable axially on the block, the engaging faces of the block and scraper being correspondingly ratcheted, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence of two witnesses.
