?atented July 10, 1906.

To all whom it may concern;

Be it known that 1;RESOUE BARNEBAS PAGE, a citizen of the United States, and aresident of LosAngeles, in the county of Los 5 jl ingeles and State ofCalifornia, have invented 3a new and Imfproved Excavating Apparatus,

act description. My inventlon relates to improvements in IO excavating'a paratus adapted for use in ditching, dre ging, building levees, leveling land, and constructing waterways .and

canals. v

In'this invention I employ a reversible I 5 scraper having two cutting edges and adapted to be hauled in an operative condition on each trip back and forth across the ditch,

canal, or other ground it is desired to remove. With the scraper is associated means for holding it in the required 0 erative condition during the excavating an loading operation and when fully loaded, s 'd means being also effective in dumping the scraper when it reaches the pointof discharge.

Further objects and advantages of the invention will appear in the course of the subjoined description, and the actual scope thereof will be defined by the annexed claims.

Reference is to be had to the accompanying drawings, forming a part of this specifi cation, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is aperspective view of my improved reversible scraper and adapted for use in an excavating apparatus for the pur poses hereinbefore mentioned. Fig. 2 is a vertical sectional view through the reversible scraper, showing it in .an operative position for the purpose of loading itself and for transporting its load .to the dumping-point. Fig. 33s a sectional view somewhat similar to Fig. 2, but showing the scra er in an inverted or dumping position; and ig. 4-is a diagrammatic view illustrating the arrangement of mechanism for operating the scraper.

The reversible scraper A of my invention *isshown by Figs. 1 to 3, inclusive, as consistin of longitudinal members A A the end p ates B B and an intermediate artition C. The longitudinal members, A 2 are disposed at an angle to each other, and they ollowing is afu'll, clear. and ex may be made of a single piece of sheet metal bent to the required form or in separate piecesandunited in any suitable way. As shown, however, the two members are in one piece, and they extend the full len th of the aseous BARNEBAS PAGE, or vLes ANGELES, CALIFORNIA, ASSIGNOR or scraper, each member being provi ed with a cutting ed e a. The end walls B B. are united to t e members of the scra er in any a proved Wayas, for example, lgy the an g e-pieces d, which are riveted to said memers and to the walls, as shown by Fig. 1, said walls having curved outer edges bounded by marginal flan es d. The inner surfaces of the end Wa s B B are smooth to prevent the lodgment of dirt in unloading the scraper by dumping thesame. The corner formed by the union of the members A A is reinforced by a longitudinal an le-strip e, which is riveted to the inside of t e scraper. The partition 0 is secured in an desirable way within the scraper, preferab y midway between the ends BB, so as to divide the scraper into two compartments. The ends or walls B B are braced by the employment of suitable stay-rods e, which are fastened to the walls and to the angle-strip e.

The improved scra er is adapted .to be drawn in either directlon by suitable power appliances, and it is reversible, so that it will load itself when drawn in one direction or the other. When the scraper is in the position shown by Fig. 2, the member A constitutes the bottom and the member A is the back, the scraper being movable in the direction of the. arrow in said Fig. 2, so-that the cutting edge a will cut through the soil and load the scraper on the advancement thereof. When its frictional engagement with the soil over which it travels, I contemplate the employ ment of metallic shoes D, which are made of' metal and secured by rivets or otherwise to the outer surfaces of the members A A These shoes increase the strength of the scraper and minimize the wear thereon, said shoes being removable when worn and adapted to be replaced by other metallic strips vilhich are adapted to serve the purposes of s oes.

I

' With the scraper I have associated means for dumping or tilting the 'same when it reaches the limit of its movement ineither direction, and said means includes the clevises I J, the same extending'in op osite directions from the scraper and pivote to the ends and the partition in peculiar relation to the pivthe draftbails F G. The clevis I, which extends from the scra er in the same direction as the draft-bail F, as ivotal connection at 'L with one end B and t e partition C, said pivots i being located in a plane between the pivots f g of the two draft-bails. J has pivotal connection at 7' with the other end B and the partition C, said ivots 9' being located in a plane be tween tr e pivots f g of the two draft-bails F G. The clevises I J are located in' the res ective compartments of the scraper formed by the ends B B and the partition C, and said clevises are forked or bifurcated in order that they may straddle the spaces between the ends and the partition, thus providing for the pivotal connection of the clevises in the manner described. The clevis I, as heretofore stated, extends from the scraper in the same direction asthe bail F, whereas the other clevis J extends in an opposite direction to the clevis I and in the same direction as the bail G, as shown by the drawings. Each clevis is provided at its front end with an angular arm K, and each clevis is of such length that the angular arm will project in one posi tion around the cutting edge a of the scraping member and have engagement with the back of said member in a way to prevent it from coming in contact with the cutting edge and from dulling or nicking the same.

To the angular arms K of the two clevises are connected the adjusting-lines L L, which are adapted to pull on the clevises and assist in maintaining the scraper in its operative drawn across the ground.

In Fig. 4 of the drawings I have illustrated one embodiment of mechanism for hauling, dumping, and for keeping the scraper in its proper positions; but I do not desire to con- 1 ,fine myself strictly to the employment of any special means for the operation of the scraper. Derricks M N are erected or located at the said draft-clips of respective ends of the field of operation of the scraper or on opposite sides of the ditch or excavation from which it is desired to remove the material. T he derrick M is equipped with drums m m and with sheaves m m m and*m The haulage-cable H extends and is coiled on the drum m. The adjusting-line'L leads from the clevis [over the sheave m, under the sheave m thence over from the bail F over the sheave 'm the sheave m and is coiled on the drum m.

The sheave-m is adapted to be pulled in adownward direction by "any suitable appliancesuch, for example, as a cable m".

whereby the sheave "m. is movable vertically with res ect to the sheaves m "m for the purpose of s ortening the adjusting-line L. The other derrick N is similarly equipped with drums p p and with sheaves p p p 11 haulage-cable H leads fromthe bail G of the scraper over the sheaves p and is coiled around the drum The adjusting-line L extends from the cIevis J of the scrapenover under the sheave p and over the sheave from whence it passes through and aroun the drum 1). The sheave p is disposed for vertical movement in a path between the sheaves p 1% for the purpose of shortening the adjusting-line L, and the downward movement may be given to this sheave p by any suitable appliancessuch, for example, as the cable 12 I The drums on the respective derricks may be operated by an engine or motor of any suitable character, and with these drums are associated ordinary friction-clutches and other devices, which control the operation of said drums. In order to move the scraper toward the right in Fig. 4, the drums m or p may be driven in order to draw on the cables L or L for moving the scraper A to the operative position. (Shown by full lines). The drum m is now driven for the pur the sheave The i ose of coiling the cable H thereon and ban ing the speed in order to pay out the cables H and L. The several cables which are connected to the bails and clevises of the scraper cooperate in maintaining the'scraper in the desired position during the operation of cutting through the soil and loading the excised material into the scraper; but as soon as the scraper is,loaded the drum m is slackened somewhat in order to correspondingly slacken the cable H, and thus revent the scraper from taking up material in excess of its capacity, after which the drum 'm is again driven at the required speed, so as to take up theloading-cable H as rapidly as the scraper is advanced toward the place of unloading.

To unload the scraper, it is dumped to the position indicated by dotted lines in Fig. 4 and by full lines in Fig. 3, and this is accomplished by slackening the cables H, H, and L; but the drum m is driven in order to haul on the line L and the clevis I, so as to pull the scra er over to the desired dumping position. 1813 before the scraper is fully inverted the drum m and the cable H are again brought into operation s0 as'to pull on the scraper and make the haulage-cable assist the adjusting-line in emptying the scra er. The curved flanges d on the end walls B of the scraper serve as shoes or runners when the scraper is invertedj In the practical operation of the scraper the cables can be so controlled as to revent said scraper from dumping itself W en its cutting edge is in contact with extra hard ground or roots. In case the scraper encounters an obstruction the strain on the cables can be increased by the o eration of the engine on one side of the ditc to overcome the tendency of the scraper to tilt or turn. Itis evident that after hauling the scraper to the dumping-place adjacent to one of the.

derricks the other set of cables and drums can be brought into service for reversing the position of the scraper and for hauling it in an opposite direction in a way to out through the soil and load itself with the excised material, after which the scraper in the reversed position ma be dumped in the manner described, an said scraper can thereafter be reversed, so as to operate when moving in the first-named direction. (Indicated by the ar row.

Tlie employment of the vertically-movable pulleys m or p on the respective derricks is advantageous in drawing on'the lines L L to make the clevises tilt or dump the scraper, because when the scraper reaches its dum ing position, to which it is hauled by the diums m m or p p, the cables/m or p may be drawn taut, so as to pull the ulleys 'm, or p in a downward direction, thus increasing the pull on the cables L or L and inverting the position of the scraper without operating either of the drums m or p from the engine.
