Application iled October 8, 1906. Serial No. 338,074

To all zul/1,0m it may concern:

Be it known that I, TORBJRN LINGA, a subje'ct of the King of Norway, residing at Thor, in the county of Humboldt and State of Iowa, have invented a new and useful Ditching-Machine, of which the following is a specification.

This invention relates to ditching machines and its object is to provide a self-propelled machine of this character having means of' novel construction for digging ditches to desired depths and for discharging the removed dirt at the sides of the dito A still further obj ect is to provide a ditching machine which is of very simple construction, which can be readily manipulated, and which has simple means for adjusting the digging mechanism vertically.

With the above and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a side elevation of the machine; Fig. 2 is a vertical transverse section; Fig. 3 is an enlarged elevation of the digging wheel one of the buckets being partly broken away; Fig. 4 is a transverse section through a portion of the wheel and the deflecting plates or guards; and Fig. 5 is a detail view showing the mechanism for raising or lowering the wheel carrying frame.

Referring to the figures by characters of, reference, 1-1 are side beams connected by end beams 2 to form the main frame of the machine, said frame being supported by traction wheels 3. Parallel beams 4 are arranged longitudinally within the frame and carry inclined plates 5 which co-operate with similar plates 6 upon the beams 1 to form elongated hoppers 7 open at the bottom. Upstanding from the beams 4 are uprights 8 on which are mounted channeled side strips 9 connected at their upper ends by means of a strip 10 so as to form a frame which is slidably mounted upon the standards 8. Arms 11 extend downward from the side strips 9 and constitute supports for the stationary axle 12 of the digging wheel. This wheel comprises a hub 13 to which is secured a disk 14 and secured to the disk is a series of radiating arms 15 each of which has a yoke 16 at its upper end in which is secured a cylindrical bucket 17 the forward or advancing end which is preferably formed at an acute angle to the radius of the wheel. Each bucket is open at its ends and has a follower 18 slidably mounted therein and connected by a link 19 with a lever 20. All of these levers 20 are pivoted as at 21 upon the disk and are limited in their movement in one direction by a collar 22 which is fixed upon the axle.

The collar 22 has a rojection 23 thereon extending into the path) of ends 24 which are offset from thev levers 20. Curved T-irons 25 are secured to an outer ring 26 which connects the arms 15 and these T-irons are dis-f posed directly in front of the buckets 17 andv extend to points close to the levers. 20 in front thereof. A smaller concentric ring 27 is secured to the arms 15 and is connected to has an ear 38 through which extends a screw 39 bearing at its lower end in the bracket 40 on one of the beams 1 and at its upper end in a cross strip 41 arranged upon the

uprights

8 and 37. An ear 42 also extends laterally from the strip 10 and is engaged by a screw 43 bearing at its lower end in a bracket 44 supported by one of the beams 4 and at its upper end in the cross strip 41. The two screws are provided at their upper ends with sprockets 45 and each sprocket has achain 46 thereonwhich extends around a double sprocket 47 secured upon a short shaft 48 which is j ournaled in the cross strip 41 and carries a beveled gear 49. Secured to the side strips 9 are inclined deflecytor plates 50 the upper edges of which are curved so as to be concentric with the ring 26 and these edges are overlap ed by the T- irons 25. These deflector p ates 50 are so disposed as to direct dirt into the hoppers 7 as clearly shown in Fig. 2. Journaled in brackets 51 extending forward from the

uprights

8 and 37 is a shaft 52 carrying a pulley 53 and 'a beveled gear 54. This gear meshes with a gear 55 on the upper end of the verti.- cal shaft 34 and said gear 55 carries a cog 56 which meshes with a similar gear 57 disposed upon a short shaft 58 journaled in suitable .Spports connected to the upright 37. This IOC:

IIO

shaft 58 has a beveled gear 59 thereon disposed directly below the gear 49. A shaft 60 is j ournaled upon the cross strip 41 and is provided at one end with a beveled gear 61 while its other end is forked as at 62 and carries meshing gears 63. A yoke 64

embraces gears

61 and 63 and is formed at one end of a lever 65 which is fulcrumed upon a supporting bracket extending from the upright 37. A suitable motor 66 is carried by the frame of the machine and drives a belt 67 extending around the pulley 53. A beveled gear 68 is also driven by the motor and meshes with a gear 69 upon one end of a shaft 70. This shaft has a worm 71 thereon which meshes with a worm wheel 72 on the axle 73 of one pair of wheels 3 so that the entire gear can be slowly propelled. It is of course understood that any suitable means may be employed for starting, stopping or reversing the machine and mechanism other 'than that shown may be used for propelling the machine it merely being necessary to provide means whereby the machine can be propelled slowly in a desired direction.

In using the machine the wheel carrying frame made up of

strips

9 and 10 and arms 11 is adjusted to a desired elevation by swinging the lever 65 so as to bring either the gear 61 or the gears 63 in mesh with

gears

49 or 59. The motor will of course drive the shaft 34 by means of the bolt 67, shaft 52 and

gears

54 and 55 and rotary motion will in turn be transmitted from the shaft 34 through gears 56 and 57 to shaft 58. By manipulating the

gears

61 and 63 the gear 49 can be caused to rotate in a desired direction so that the

screws

39 and 43 will be rotated to raise or lower the wheel carrying frame and the bracket 35 on which the gear 33 is mounted. When the wheel has been elevated to a desired point it will be supported by the

screws

43 and 39 and rotary motion will be transmitted thereto from shaft 34 through

gears

33, 32 and 30. The gears are so proportioned as to cause the wheel to rotate slowly, preferably about three times a minute and the forward ends of the buckets will be brought successively into contact with the ground and the pressure of the dirt entering the buckets will press the follower 18 backward until the levers 20 are stopped by theh arms 15. As the buckets move upward carrying the dirt therewith the ends 24 of the levers 20 will be brought successively into contact with the projection 23 and will be tripped thereby so as to force the follower 18 forward and discharge the dirt from the buckets. The discharged dirt will fall upon the T-irons directly in front of the bucket and will then be directed to opposite sides of the machine and into the hoppers 7 by the plates or guards 50. The T-iron 25 of course prevents the dirt from falling between these guards. The machine travels forward slowly as the wheel rotates and therefore the length of the ditch will be gradually increased and the dirt removed therefrom will be deposited along the sides thereof at points where it can be conveniently reached for the purpose of refilling the ditch. It will of course be understood that any suitable means may be employed for raising the gear 33 out of mesh with gear 32 when it is desired to stop the rotation of the digging wheel and I do not deem it necessary to illustrate any particular means for shifting said gear. Also instead of the particular means for transmitting motion to the guards from the shaft 34 any other desired mechanism may be employed provided the same is capable of being manipulated to reverse the rotation of the guards whenever desired.

The preferred form of the invention has been set forth in the foregoing description but I do not limit myself thereto as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof7 and I therefore reserve the right to make such changes as fairly fall within the scope of the claims.
