Fig. 15 is a fragmentary detail of the scraper.

The ditch digger and grader "is mounted or constructed upon a motor vehicle comprisinga rear axle 1, a front axle 2, a frame 3 mounted. upon the axles 1 and 2, wheels 4 upon the rearaxle, wheels 5 upon the front axle, and an engine 6 upon the forward end of the frame 3.

Sills 7 and 8 are mounted below the axles 1 and 2 inside of the wheels 4 and 5 and rigidly secured to the side bars 9 and 10 of the frame 3 by braces 11. The sills 7 and 8 extend a considerable distance back of,the rear end of the frame 3 and a considerable distance in front of the forward end of the frame 3, and the sills 7 and 8 are just above the ground. An extension frame 12 is constructed upon the forward ends of the sills 7 and 8 substantially on a level with the frame 3.

A winding drum 13 is mounted transversely and horizontally at the forward end of the frame 12. The winding drum 13 is mounted loosely upon a shaft 14 and is controlled by a clutch construction 15. A shaft 16 is mounted in the frame 12 behind the shaft 1.4 and connected to the shaft 14 by spur gears 17 and 18. The shaft 19 is con nccted to the forward end of the engine shaft 20 by a coupling 21, and a bevel pinion 22 is mounted upon the forward end of the extension shaft 19 and meshes with the bevel pinion 23 upon the shaft 16. The pinion 22 is controlled by a clutch construction 24.

The shaft 16 extends beyond the side of the frame 12 and has an end 25 adapted to be engaged by a suitable crank wrench for starting the engine. In starting the engine the clutch 15 is disconnected and the clutch 24 connected, and after the engine is started the clutches 15 and 24 may be manipulated as'desired.

A brake drum 26 is fixed upon the shaft 14, a brake band 27 is connected to an abutment 28 at one end and extends around the brake drum 26, a rod 29 extends through the abutment 28 and connects to the free end of the band 27, and a hand lever 30 operates the rod 29 so as tocontrol' the winding drum 13. 1

The lever 31 controls the clutch 24, the rod 32 controls the lever 31, and the hand lever 33 controls the rod. The scraper or shovel 34 has a back. 35 fitting against'the forward end of the frame 12 and against a stop 36, and the scraper has a bottom 37 extending forwardly from the lower ec go of the back and sides 38 and 39 extending upwardly from the ends of the bottom 37.

The scraper 34 is pushed against the bank 40 to excavate the bank by operating the motor vehicle forwardly.

A derrick 41 is constructed upon the rear ends of the sills 7 and 8, and the details of the derrick are as follows:

A crosspiece 42 connects the rear ends of the sills? and 8, a vertical post 43 rests upon the center of the crosspiece and is rigidly secured in place, lower braces 44 and 45 connect the intermediate portion of the post 43 to the sills 7 and8, upper braces 46 and'47 are connected to the upper portion of the post 43 by joints 48 and 49 so that the braces 46and 47 may swing to or from the sills 7 and 8', and shoes 50 and 51 are fixed upon the lower outer ends of the braces 46 and 47'. Ropes or cables 52 and 53 are connected to the upperend of the post 48and extend outwardly and downwardly through openings 54 in the braces 46 and 47. Knots 55 v are formed upon the ropes or cables and the openings 54 are large enough for the knots to pass through; Slots 56 extend from the openings" 54 and the slots 56*are large enough for the bodies of the ropes and ,too small for the knots so that the braces 46 and 47 may be swung outwardly and the ropes 52 and 53- passed through the openings to the desired extent and then the braces swung downwardly or inwardly and the ropes will engage in the slots 56 and be drawn taut. Knotted ropes 57 and 58 are connected to the lower end of the brace 46 and engage forks 59 and 60 fixed upon the side bar '7 to limit the outward swing of the brace 46. In a like manner knotted ropes 61 and 62 are'attached to the lower end of the brace 47 and engage forks 63 and 64 fixed upon. the sidebar 8 to limit the outward swing of the brace 47. A pulley 65 is mounted at the lower end of the post 43 and a pulley 66' is mounted at the upper end of the post. The parts are'adjusted so that the shoes 50 and 51 will move easily upon the face of the ground when the motor vehicle is pushing the scraper, and so that the shoe 50 will rest upon the ground when the scraper is elevated as shown in dotted lines in Fig. 1,. the scraper being swung to the left, and so that when the parts are shifted toswing the scraper tothe right the shoe 51 will rest upon the ground and brace the derrick.

A central crosspiece 67is fixed upon the side bars' 9 and 10 and guy anchors 68 and 69 extend upwardly from the ends of the crossp'iece67f The crosspiece 67 is a channel bar with the-channelupwardly and the guy anchors-68andi69 arefblocks inserted" downwardly into the channel and fastened."

boom 72.

Referring to Fig. 6, a post socket 70 is fixedat the center of the 'crosspiece 6'7 and extends upwardly andthe post 71'is loosely mounted in the socket 70 so that the post may bereadily removed. iThe post 71 extends upwardly to a considerable height.

The boom 72 is a long heavy timber substantially as long as the side bars 7 and 8. A fitting 7 3 is fixed upon the rear end of the A second fitting 74 is hinged to the rear end of thefittingl73 and has a cir cular stem 7 5 fitting in a vertical bearing T6 secured-to the. post 43, so that the boom 72 may swing'up and down upon the hinge pin 77 and swing laterally upon the stem 7 5. The boom 72 normally rests in a horizontal position and as shown passes upon the lefthand side of the post 71 when it is desired to dump the scraper at the left-hand side of the machine.

Referring to Fig. 11, a bracket 1? is secured to the post 71, a shaft 2 is fixed in the bracket l a spiral spring 3* is fixed upon the shaft 2 at its inner end and the outer end of the spring 3 is fixed to the drum 4. A pawl wheel 5 is fixed to one end of the drum 4. A lever 6 is mounted upon a pivot. 7 and has a pawl 8 engaging the pawl wheel 5 and a handle 9 extending upwardly and outwardly from the post 71. The guy '7 8 is attached to and wound upon the drum 4 and extends upwardly over the guide roller 1 at the upper end of the post '71, and the guy 78is connected to the boom 72 some distance in front of the post 71.

If it is desired to change the arrangement and dump the scraper at the right-hand side of the machine the post 71 is removed from the socket and turned half way around, the boom 72 swung over to the righthand side and the post 71 replaced in the socket.

At guy 7 9 is connected to the guy anchor 68 and passes over a pulley 80 at the forward end of the boom '72 and downwardly and is connected to the central portion of the top of the back 35 of the scraper.

The scraper bail comprises side bars 81 and 82"connected to the forward end of the boom .72 bya pin 83 and extending downwardly and outwardly and connected to the sides 38 and 39 of the scraper by pins 84 and 85. The pins 84 and 85 are in front of the center of the scraper, so that the load of dirt in the scraper will tend tothrow the scraper backwardly and not forwardly. A stop knot and forwardly and is attached to thehook 87 fixed in the forward end of theboom 72. When the drum 13 is operated to Windthe cable 86 the cable will pull upwardly upon the forward end of the boom 72 thereby raising the scraper 34 carrying the load of dirt, and as the scraper is raised the tension of the guy 79 pulling upwardly on the back 35 will hold the scraper upright to carry the load, and as the scraper continues to go up wardly the tension of the guy 79 willmove the forward end of the boom 72 to the left until the desired height is reached, then an extra strain upon the cable 86 will upset the scraper and dump the load as shown in dotted lines in Fig. 1. Releasing the cable 86 will allow the weight of the scraper to swing the boom 72 backwardly toward its normal position.

lVhen the boom 72 goes upwardly the tension of the spring 3 will wind the guy 78 upon the drum 4 and the pawl 8 will hold the drum 4 to hold the guy 78, so that when the boom 72 starts downwardly the guy 78 will be short and hold the scraper 34 some distance above the ground. A nut 3 is formed in the guy 78 in front of the roller 1 to limit the winding up movement of the drum 4 Then the boom 72 has been lowered until the guy' 78 is tight the boom 72 will swing laterally toward the post 71 thus bringing the scraper 34 directly into line and then the boom 72 will strike the handle 9 and release the pawl 8 from the pawl wheel 5 and the weight of the boom will unwind the guy 78 from the drum 4 and allow the scraper 34 to settle straight down into place. Then the power will be applied to move the vehicle forwardly to push the scraper into the bank 40 to obtain a new load.

lVhen it is desired to dump the dirt to the right instead of to the left the guy 79 will be connected to the guy anchor 69 and the boom 72 will be upon the righthand side of the post 71. v

Referring to the modification shown in Figs. 13, 14 and 15, the elevating frame 88 is built upon the extension frame 12. The main feature of the elevating frame 88 consists of the double track bars 89 and 90 extending upwardly from the forward end 7 of the extension frame 12 and making a quarter turn above the extension frame 12 and then going straight upwardly and outwardly at right angles to the axis of the machine. Posts 91 and 92 support the upper outer ends of the track bars 89 and 90 and are adapted to rest upon the ground and to be moved along the surface of the ground. .At'the upper ends of the track bars 89 and'90 the track bars are separated to produce the single tracks 93 and 94 and 95 and 96.

sides 100 and 101 by pins 103 and 104. Stops 105 are secured to the sides 100 and 101 to allow the bail 102 to swing upwardly to a vertical position against the stops. The pins 103 and 104 are near the back parts of the sides and the stops 105 hold the scraper from tipping forwardly. lVide wheels 106 and 107 are mounted at the lower back corners of the sides 100 and 101 to run upon the double track- bars 89 and 90 and to run upon the single track bars 93 and 94. Narrow wheels 108 and 109 are secured to the upper rear corners of the sides 100 and 101 in planes to run upon the double track bars 89 and 90 and to run upon the single track bars 95 and 96.

The cable 110 leads from the winding drum 13 upwardly around the guide pulley 111 upon the extension frame 12 and upwardly around the guide pulley 112 and downwardly around the guide post 113 and is attached to the center of the bail 102. The clutch lever 114 for operating the clutch construction 24 is mounted upon a pivot pin 115 secured to the frame and extends across the frame and is connected to a lever 116. The lever 116 is mounted upon 'a pivot 117 and has an eye 118 in its free end, and the cable 110 pa'ssesthrough the eye 118. A nut 119 is formed in the cable 110 so that when the drum 13 is operated to pull the scraper 97 to the to of the elevating frame 88 the nut 119 will engage the eye 118 and throw the clutch 24 out and the weight of the scraper 97 will pull the cable 110 the other way and return the scraper to its normal position.

The hand lever 120 is mounted convenient to the operator and a link 121 connects the hand lever 120 to the lever 114 so that the operation of the scraper may be controlled by the hand lever 120 and the nut 119 and the eye 118 will then serve as a safety device to stop the pull upon the scraper 97 when it has reached its limit of travel.

The vehicle will be moved forwardly to push the scraper 97 into the bank and load the scraper, then the hand lever 120 will be operated to apply the power to the drum 13 and the scraper will be lifted bodily and travel along the tracks 89 and 90 until the upper end of the elevating frame is reached, then the wheels 108 and 109 will travel upon the tracks 95 and 96 and the wheels 106 and 107 upon the tracks 93 and 94, and this operation will dump the load from the scraper 97 over the back 99. The wheels 1 06, 107, 108 and 109 have flanges to hold the wheels upon the track bars.

While I have shown a simple form of motor vehicle for mounting and operating a ditch digger and grader it is obvious that the ditch digger and grader may be built upon or mounted upon any of the usual forms of tractors and any of the usual forms of motor vehicles such as trucks or automo-- biles.

Thus I have produced a ditch digger and grader comprising the combination with a motor vehicle, of a scraperadapted to be pushed forwardly by the direct action of the motor vehicle, and means whereby the power plant of the motor vehicle takes the loaded scraper from its digging position'in front of the motor vehicle, carries the loaded scraper upwardly and to one side,dumps the load and returns the empty scraper to dig a new load.

Various changes ma be made without departing from the spirit of my invention as claimed.
