WILLIAM G. PRICE, OF SIOUX OITY, IOWA, AssIGNOR OE ONE-HALE To GEORGE E. MOTT, OE NEW ORLEANS, LOUISIANA) MACHINE FOR BUILDING EIVIBANKMENTS.

SPECIFICATION forming part of Letters Patent No. 528,891, dated November 6, 1894.

Application filed February 23 1394. Serial No. 5011159- (NO 11105613 .To all whom it may concern,.-

Be it known that I, WILLIAM G. PRICE, a citizen of the United States,` residing at Sioux City, in the county of Woodbury and State of Iowa, have invented certain new and useful Improvements in Machines for Building Embankments; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same.

My invention relates to improvements in excavators and has more especially to do with machines for building forming levees or embankments and the objects of my invention are, first, to provide a power wagon and a sheave wagon or movable guy rope anchor wagon to be placed at some distance therefrom and means forexcavating the earth between said wagons and conveyingit out over the levee and dumping it; second, to propel said sheave and anchorwagon by power furnished-by the power wagon; third, to construct the drag scoop so that it can be filled and dumped out over the center of the levee Without the aid of any one' to handle it and, fourth, to provide a boom and mast supporting the same on the power wagon so that the scoop may be carried out over the center of the levee and dumped. I accomplish these objects by the vdevices described in the following specification and illustrated in the accompanying drawings, in which-' Figure l. represents a side elevation of my invention in operation building alevee. Fig. 2. is a top plan of the same. Fig. 3. is aside elevation of the drag scoop in its lowered po? sition that it takes when filled. Fig. 4.. represents a side elevation of the same in the raised or tilted position that it takes while being dragged forward to be filled. Fig. 5. represents a top plan view oflthe power wagon, its

boom and mast and the drag scoop. Fig. 6. represents an end elevation of the power wagon and its mast and'boom. Fig. 7. represents a side elevation of the same. Fig.`8. represents a top plan view ofV the sheave and guy rope anchor wagon. Fig. 9. representsa detail side elevation of the gearing for operating said wagonto move it forward and,

Fig. 10. represents a central horizontal section I through the clutch gearing for'operating the sheave wagon and allowing it to turn a curve at the same time. ,k

A in the drawings represents the power wagonv mounted on wheels o, which are pro. vided with'spurs a' so that they will not slip on the soft earth when the said wagon is being propelled forward by its own power. This wagon is adapted to travel along the berm of the levee with its wheels in furrows cut in the ground by a plow so that there will be no lateral slipping of the Wheels while the devices are in operation when the lateral strain is the greatest. The sheave or guy rope wagon Bis also mounted on wheels b having spurs b similar to wheels a on the power Wagon, so that they will not slip over the earth while the'wagon is being moved forward by power applied to said wheels as hereinafter described. This sheave wagon is mounted or placed at some distance from the wagon A and also. has its wheels set in furrows to prevent lateral slipping when a drag scoop is being operated. The said drag scoop is adapted to travel in the barrow pit and between the sheave wagon and the end of the boom D which is movably mounted on the power wagon A. This scoop is formed of an angular shoecthe vertical portion of which is provided near the top with a pulley wheel c over which the power rope E is passed before it is secured to the rear end Of the scoop or'bucket proper. This bucket is preferably rectangular inform and has its upper side Vand forwardend open, said forward endbeing slightly depressed so as to form a scoop like edge which willfreadily bury itself under the surface when the'scoop is in the position shown in Fig. 4.L The forward end of the scoop is also provided -on its under side with lugs c which are pivotally connected to the forward end of the horizontal portion of the base c so that said scoop can rise and fall into the respective positions shown in Figs. 3 and 4. A power rope E is attached to the forward end of the'said scoop and passes abouta pulley d on the end of the boom D and then to i and about a pulley f on the yforward end of the power wagon and then to the power drum loo o of the same.

5 to and about a pulley f similar to the pulley fand to and about the sheave Bon the sheave wagon and then over thepulley c of the drag scoop and then is attached to the rear end of the said scoop as before described. Thus 1o when the rope E is tightened the scoop assumes the position shown in Fig. et. and on then being moved forward in the barrow pit it scoops the earth therefrom untilit is filled, when the rope E .is slackened allowing the scoop to assume its normal position as shown in Fig. 3, the scoop continuing its forward movement by being pulled by the rope E and ascends the inclined inner side of the levee and' is drawn to the middle of the same when 2o the rope E is slaokened and a sudden pullis given to the rope E in the direction opposite tothat in which the scoop has been traveling which raises the scoop into the position shown in Fig.A 4. and at the same time draws it back- 2 5 wardrand thus the earth is dumped therefrom onto the levee and the operation is then repeated the drag scoop being first returned to l y wagon has a fifth wheel connection ai with the said wagon so that said axle may be turned its former position by the power rope E.

In order to support the long heavy boom D 3o which is necessary in order to cause the scoop to move to the middle of the levee, a mast G is mounted on the power wagon by having its lower end set in a socket so that it may rock slightly if necessary or rotate and the end of the boom is pivotally connected to said mast near its lower end. The mast is held in its Vertical` position by means of a rigid lateral brace g and a guy rope g which latter passes from a tightening winch G about a pulley at 4o the top of said mast and then to the anchor winch G2 about a pulley at the top of the mast and then to the outer end of the boom where it is made fast andI the boom thus supported in the desired position above the middle of the levee and not far above the surface It will be seen by reference to Fig. 4. that the boom does not extend directly at right angles to the power wagon but is inclined slightly forward so that the scraper when` being pulled forward will not come in contact with any part of said power wagon and thus have its contents spilled. The boom can be swung around in any direction` and raised. and lowered because of the socket connection of the mast to the power wagon 6o and its own pivoted connection to said mast.

The power for operating the drums F, F consists of an ordinary double cylinder steam engine and boiler which operate said: drums through any ordinary and well known geariugsothat said` drums may be operated independently of one another.

It becomes necessary as the work on the -wagon andthe sheave wagon forward so levee progressesl to move both the povfler t at the scoop may find a new barrow pit. The power on the power wagon that operates the said scoop is then brought into use to propel said wagons forward as follows:

A sprocket I is loosely mounted on the shaft carrying the gears that operate the drums and is caused to turn with said shaftby means of a clutch i loosely keyed to said shaft and forced into engagement with said wheel by a hand lever i. A sprocket chain J connects `this sprocket wheel with a similar sprocket wheel IV mounted on a shaft] which is journaled in hangers j pendent from the floor of -the wagon. This shaftj is provided at each end with a small gear wheel la, said gearsbeing adapted to mesh respectively with cog teeth 7c formed on the inner faces of the rims of the' two rear wheels of said powerv wagon and thus when the hand lever t' is pressed forward the sprocketwheels and chain and gear wheels are operated and the wagon propelled forward. The said wheels a, of the power jwagon are all mounted loosely on their respective axles.

The axle a2 of the front wheels of the power from side to side by means of the guiding mechanism which consists of" a vertical shafty i d4 provided with operating chains c2` and hand Lwheel c3 and supported on the wagon by a spider support c4. The sides of the forward 4end of the wagon are cut away as at A to i allow the aforesaid movement of thewheels.

To move the sheave wagon forward a f riction disk L is rigidly mountedi` on; the shaftl which carries the sheaveV B and said sheave 1 and disk are adapted to` be forced into con Atact with each other and thus operate the said shaft l as hereinafter described.

The sheave B is provided with` a sleeve b2 which is journaled in one of the bearings Z ,and the shaftl passes loosely through` this sleeve. The sheave is rotated by the power rope E from the power wagon` andthe engagement of said sheave with the friction disk is, `caused by means of the` hand lever Oi which when pressed backward against the end` of `sleeve Z2 willi` cause the sheave to engage the `friction disk and rotate` the same and the shaftZ which carries it. A spur m is attached to the end of the shaft Z' and meshes with a `bevel gear M: which is loosely mounted on the abutting ends of two independent shafts n, n. These latter shafts each; carry a bevel said gear by means of pinsp so as to be ca- `teeth of said spurs engaging the gears n2, n.3

3 and causing the latter toboth turn with the gear M. The shafts n, n' are mounted in bearings r, r, and are provided on` their end's with small gear wheels s, s,which mesh with ICO IIO

i pable of rotation axially on saidpins,th.e cog cog teeth s formed on the inner surface y of the tires of the rear wheels of the wagon and thus the -said wagon is propelled forward.

Vhen the shaft Z is rotated the spurm engages and rotates the bevel gear M which also rotates the gears n2, n3 because of the connecting spurs 0, o and the shafts n, n thus operate and move the wagon forward.

If it is necessary to move' the Wagon in a curve one of the gears fn? or n3 can move in one direction and the other in the opposite direction or one may move faster than the other as is necessary in making such a turn or curve. The wheels of the sheave wagon are all loose on their respective axles and the front axle and its wheels are 'capable of movement for guiding in the same manner as those of the power wagon. The sheave wagon is also provided with a tongue P by means of which it may be drawn by horses if so desired. By my arrangement of the sheave or anchor wagon at a distance from the power wagon I am enabled to use the long heavy boom necessary to convey the material in the scoop to the very center of the levee, because I can support the mast for said boom by guy ropes to said anchor Wagon. If I did not have the sheave wagon at a distance this would be impossible as the strainon the mast would be too great for anyordinary guy rope attached to the wagon itself or any other object near it, which guy rope would of coursehave to be changed every time the wagon was moved.

The shoe of the drag scoop might be lprovided with wheels or rollers to lessen the friction between it and the ground.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A drag scoop for an excavator comprising in its construction a suitable shaped shoe, a scoop proper pivoted at the forward end of said shoe, means for raising the rear end of the scoop proper and thus causing it to [ill and after the scoop is filled permitting it to lower to its normal position and means for drawing the drag scoop forward, substantially as described.

2. A drag scoop for an excavatorcomprising in its construction a suitable shaped shoe, provided with a guiding support at its upper end a scoop pivoted near its forward end at the forward end of the shoe, a rope attached at the lower rear end of the shoe for elevating said rear end and passed over the guiding support on the shoe and permitting it to lower to its normal position and a rope attached to the forward end of the shoe for drawing it forward, substantially as described."

3. In an excavator the combination of the power wagon having the extended boom and mast therefor, a sheave wagon placed'at a distance from said power wagon, a drag scoop adapted to operate between said sheave wagon and the end of said boom and a guy rope from said sheave wagon to the said mast, substantially as described.

4. In an excavator the combination of the power wagon provided with means for moving it forward and having an extended boom and mast therefor, asheave wagon placed at a distance from said power wagon and provided with means for. moving it forward, a self dumping drag scraper adapted to operate between said sheave wagon and the end of said boom and a guy rope from said sheave wagon to said mast, substantially as described.

'5. In an excavator the combination of a power wagon provided with gearing for mov-y `6. In an apparatus for constructing levees the combination of a power wagon adapted to be moved by itsown power and provided with a mast and extended boom, a sheave and anchor wagon placed ata distance from the power wagon and adapted to be moved forward by power from the same, a drag scoop and means for moving it between the said sheave wagon and the outer end of the said boom and causing it to dump at the latter place, and a guy rope from said anchor or sheave wagon to said mast, and a guy rope from said mast to the end of said boom, substantially as described.

7. In an apparatus for constructing levees the combination of the power wagon and a sheave and anchor wagon placed at a distance therefrom, both wagons'being adapted to move forward by power from the power wagon and a drag scoop adapted to move between said wagons and means for causing said scoop to either scoop the earth or slide smoothly over the same, substantially as described. s.

. 8. In a machine for building embankments, the combination of a movable power Wagon, a movable sheave wagon, means for connect- `ing the two wagons, and a tilting drag scoop connected to and operated by said wagons, whereby as the scoop is moved forward its rear end is raised, and when the scoop is filled it lowers again and is dumped at the desired point, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
