SPECIFICATION forming part of Letters Patent No. 695,258, dated March 11, 19 02.

Application filed September 4, 1901- Serial, No. 74,275. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. WILsON, a citizen of the United States, and a resident of St. Louis, in the State of Missouri, have invented a new and Improved Ditching and Dredging Machine, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for ditching and dredging. It is applicable to both land and marine purposes, but as here shown is in the form of a ditcher.

This specification is the specific disclosure of one form of my invention, while the claims define the actual scope thereof.

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

Figure 1 is a side elevation of the apparatus. Fig. 2 is a plan view. Fig. 3 is a fragmentary section on the line 3 3 of i Fig. 2. Fig. 4 is a section on the line 4 4 of Fig. 3. Fig. 5 is a section on the line 5 5 of Fig. 3. Fig. 6 is a section on the line 6 6 of Fig. 3, and Fig. 7 is an enlarged vertical section of one of the buckets and its chute, showing the latter in clined into dumping position.

The apparatus is provided with a suitable framing 10, which when adapted for use on land,as shown in the accompanying drawings, is mounted on wheels 11. The framing or base 10 carries a suitable motor apparatus 12, and, if desired, one or more of the wheels 11 may be connected with the motor, so that the apparatus will be steadily advanced according to the amount of material excavated.

14 represents an essentially triangularshaped rocker mounted on the base or frame 10 to swing around a circle-point 15.

16 indicates a cable connected to the rocker 14 and leading to a suitable Winding apparatus 17, by means of which the rocker 14 and the parts attached thereto may be raised or lowered to adjust the excavating devices, as will be hereinafter fully set forth.

The rocker 14 projects rearward beyond the frame 10 and carries at its rear extremity a wheel 18, on which the dredging or excavating devices are carried. The wheel 18 is provided at each side adjacent to its periphery with crown-gears 19 in mesh with pinions 20,

carried on shafts 21, mounted on the rocker 14.

2 indicates bevel-gears fastened, respectively, to the shafts 21 and in mesh with corresponding gears 23 on the shaft 15, said shaft forming the center around which the rocker 14 turns. The shaft 15 is driven by a train of gears 24, suitably connected with the motor, as shown. By means of this mechanism the wheel 18 is rotated continuously irrespective of its adjustments, which are effected by therocker 14.

Oarriedon the wheel 18 are the excavatingbuckets 25. These buckets are preferably four in number, quartered on the wheel, and they are provided, as best shown in Fig. 3, with side walls made up of sections 26, hingedly mounted at opposite sides. These sections are kept closed normally by lever-latches 27. (Best shownin Fig. 5.) Thelever-latches are fulcrumed on the wheel 18 and are pressed into active position by springs 28. (See Fig. 5.) The latches are thrown outward. to release the sections 26 of the buckets 25 by means of a rock-shaft 29, connected with the latches 27 by a crank-disk 30 and links 31.

In radial line with each bucket 25 is a dumping-chute, comprising a central web or partition 32 and side walls or flanges 33, these parts forming the double chute, as best indicated in Figs. 4, 5, and 7. The chutes are hung pivotally on arms 34, fastened rigidly to the wheel 18. The chutes are held normally in the plane of the wheel by means of latches 35, which are engaged with the inner ends of the webs or partitions 32 and pressed into active position by means of springs 36. (See Figs. 3 and 4.) As the chutes swing around the pivots on the arms 34 they wipe gear-segments 37 against pinions 38, carried on rockshafts 39, mounted on the wheel independently of the chutes. These shafts 39 carry, respectively, crank -disks 30, and consequently as the chutes swing out of the plane of the wheel 18 the

elements

30 and 31 are actuated to throw the latches 27 into inactive position, thus allowing the sections26 of the bucket 25 to swing inward and dump the contents of the bucket into the chute. (See Fig.

7.) This operation takes place when the bucket is uppermost on the Wheel. (See top of Fig, 3.) As the chute swings backward to its normal position (see Fig. 4) it wipes its in clined upper end against the sections 26 of the bucket 25 and causes them to swing backward into closed position, in which adjustment they are held by the latches 27, which again become active. This closing action is assisted toward its end by a roller 40, carried on the top end of the chute, and when the sections 26 are closed the roller bears under them. (See Fig. 4.) Each chute is provided with a crown-gear 41, fastened to the side thereof concentric with the pivot of the chute at the arms 34. With these crown-gears mesh toothed sectors 42, which are one for each chute, and mounted on the wheel to turn around pivots at the points 43. (See Figs. 1 and 3.) As the sectors 42 are thrown-in one direction or the other they impart a swinging movement to the chutes, and thus the chutes may be caused to swing outward at either side of the wheel, so as to throw the contents of the bucket laterally clear of the wheel. Each sector 42 is provided with a tail 44, said tails having transverse pins running in arc-shaped slots 45 in the wheel 18. These transverse pins of the tails 44 carry rollers 46, which lie on the outside of the wheel in position to engage a switch-point 47, lying in the path of the rollers 46, as they move around with the.

wheel 18. This switch-point is pivoted at the point 48 on an arm 49, whichis carried on the axle of the wheel 18 and adjustably fastened to the rocker 14, through the medium of a bolt 50, working in a slot 51 in the arm 49. (See Figs. 1, 3, and 6.) The switch-point 47 has located at each side thereof a rail 52, these rails being fastened on the arm 49. As the wheel 18 turns it wipes the rollers 46 against the switch-point 47, and according to the posi'tion in which the switch-point is thrown the roller 46 is caused to move sidewise, carrying with it the sector 42. As the wheel continues its movement the roller 46 rides off of the switch-point 47 and onto one of the rails 52, thus holding the sector in the position in which it is thrown until the continuing movement of the wheel '18 causes the roller to disengage the rail 52, and thus permit the sector to return to its normal position, said return being brought about by the gravity of the chute 32, to which the sector is connected through the medium of the gear 41.

The switch-point 47 is movable between two stops 53, carried on the arm 49, and this movement of the switch -point is brought about by means of a rod 54, connected with the switch-point by a pin and slot, as indicated in Fig. 1. The rod 54 extends through a hand-lever 65, mounted on the rocker 14, andanoperator standing at this lever may throw the switch-point to incline the chute to either side of the wheel 18, as may be desired. Fastened to the arm 49 is a rail 56, which is located adjacent to the axis of the wheel 18 and in the path of lateral extensions 57, formed on the latches 35, said extensions projecting through arc-shaped slots in the wheel 18. Therefore as the wheel 18 revolves the extensions 57 of the latches 35 are successively presented to the rail 56, and this causes the latches to be thrown inward against the tendency of the springs 36, thus releasing the chutes. As the chutes return to their normal position (see Fig. 4) the lower end of the web 32 rides against the latches 35 and automatically engages therewith, the latches having inclined surfaces to facilitate this operation, as shown in Fig. 4.

Assuming the apparatus to be constructed as described and the various parts assembled as in Fig. 1, the rotation of the wheel 18 will cause the buckets-25 to scoop up the earth,

in the ditch, asshown. As the rotation of the wheel in the direction of thearrow in Fig. 3 raises a loaded bucket tothe position shown the projection 57 of the corresponding latch 35 will ride against the rail 56 and the chute adjacent to said bucket will be released. The operator stationed at the lever-.65 should now throw the lever so as to adjust the switchpoint 47 for tilting the chute to that side of the wheel on which it is desired to dump the load of the bucket. This done, the roller 46 rides on the switch-point 47 and the sector 42 is thrown, thus throwing the chute laterally, so that its discharge end projects beyond the side of the wheel 18. As the chute is thrown to one side it causesone of the gear-segments 37 to mesh with and turn the adjacent pinion 38, thus rocking the shaft 39 and releasing the latches 27. The sections 26 of the bucket now drop by gravity, and the load of the bucket is dumped upon the chute along which said load passes and is discharged at one side of the machine. The roller 46 will by-this time have run off the rail 52 with which it was engaged and the gravity of the chute will return the chute and the sector 42 to their normal position. The roller 40 will close the sections 26 of the bucket 25 and the springs 28, will return the latches 27 to active position. The rotation of the wheel continues until the next bucket arrives at the dumping position, whereupon the above-described operation will be repeated.

I have not shown the gearing for driving the wheels 11, as this will be obvious to all persons skilled in the art, and by driving these wheels the apparatus maybe advanced steadily against the bank of the ditch in time with the excavating action of the machine.

In adapting the apparatus for marine purposes it will obviously have to be mounted upon a suitable vessel and this vessel propelled as the work of the excavating-wheel progresses. Owing to the chutes, which-are tiltable to either side desired, the material excavated may be conveniently dumped into scows lying alongside of the vessel which carries the excavating apparatus.

Various changes in the forms, proportions, and minor details of my invention may be resorted to without departing from the spirit thus forming the ditch, the wheel lying partly thereof, as I consider myself entitled to all such variations as may lie within the scope of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
