SELF-LIFTING SURFACING MACHINE FOR CANALS Filed Dec. 18, 1964 5 ShetS-Sheet 5 c YZ4,

INVENTOR. fr/10AM f2 l//MsoN United States Patent O 3,328,902 SELF-LIFTING SURFACING MACHINE FOR CANALS Raymond A. Hanson, R. A. Hanson Company, Palouse, Wash. 99161 Filed Dec. 18, 1964, Ser. No. 419,402 4 Claims. (Cl. 37-81) This invention relates to surfacing machines for trapezoidal canals, whether the machine be for working the soil surface or Vfor applying a lining to the canal surfaces.

Prior canal lining machines conventionally have been formed in a rigid cross-sectional conguration, the various dimensions and angles of the canal cross-section varying from one project to another. This required the manufacture of surfacing machines for each particular project to the desired specications. Prior machines utilized tracks along the side of the canal ditch for support of the machine as it travelled along the length of the canal. Subsequent machines have been mounted on crawler tracks to eliminate the temporary placement of tracks along the length of the canal. Some of these machines have been self-lifting, normally by linkages connected from the side of a rigid surfacing machine frame to the supporting crawler track assemblies. The present invent-ion is designed to simplify the structure of such a machine and to make the structure more llexible so that it can be utilized on canals having varying degrees of slope at their side surfaces. The machine also is self-lifting so that it can -be raised from a canal and moved to a new location under its own power.

-It is -a first obje-ct of this invention to provi-de an adjustable self-lifting surfacing machine that `is capable of operations along the bottom and sloped sides of a canal as it travels along the length thereof.

Another object of this invention Iis to provide such a machine with a low center of gravity when operating within a canal as contrasted with the higher center of gravity normally utilized in a rig-id frame machine.

Another object of this invention is to provide a machine that can be made in a larger size than conventional rigid frame machines so as to accommodate wide modern canal projects.

These and further objects will be evident from a study of the following disclosure, taken together with the accompanying drawings which illustrate one preferred form of the invention. It is to be understood that this form of the invention is not intended to limit or restrict the scope of the invention, which is set out in the claims that follow.

In the drawings:

FIGURE l is a front view of the machine as it operates along a canal, the canal conguration being shown in cross-section;

(FIGURE 2 is a front View of the machine in its lifted position while travelling along a level surface;

FIGURE 3 is a top view of the apparatus as shown in FIGURE l;

FIGURE 4 is an enlarged cross-sectional view taken along line 4 4 in lFIGURE 1; and

FIGURE 5 is an end view taken from the left in FIGURE 2 at an enlarged scale.

The `apparatus shown in the `accompanying drawings generally illustrates a canal trimmer having rotating yaugers and digger wheels to remove several inches of soil from the surfaces of a canal ditch that has been excavated. This disclosure is not primarily concerned with the structure of the trimming mechanism, but rather with the supporting framework and apparatus for the surfacing equipment. It is to be understood that the rice present invention is equally applicable to any type of surfacing machine for canals of this nature. Such machines include excavators, trimmers, lining machines or slipforms, and various finishing machines for the canal surfaces. The trimmer apparatus illustrated is only exemplary and for this reason, much of the detail of this equipment itself has been omitted from the disclosure.

As shown in the drawings, the apparatus includes a central rigid frame structure general-ly designated by numeral 10. The frame 10` includes transverse upwardly directed triangular braces 12 that are rigidly mounted on the basic frame structure 10. At the bottom of frame 10 is surfacing equipment including a bottom auger 13 having a rear screed 11. At each end of the auger 13 are digging Wheel assemblies 14. The auger 13 is designed to move soil to the digging wheel assemblies 14, which elevate loose soil contacted thereby and spill this soil on conveyors 31, as will be described below.

Extending outwardly from the digging wheel assemblies 14 `are side augers 15 that extend along the sloped sides of the canal walls. The side augers 15 are pivotally mounted on t-he frame 10 so as to -be movable about an axis parallel to the intended direction of movement of the frame 10 along the length of a canal. As seen, the upper end of each auger 15 is carried in a pivot bearing 16 mounted on .a crawler track unit 17 by means of a rigid bracket 18. Therefore, each auger 15 can be swung in la vertical -direction about its lower pivot and is free to accommodate any particular langle as defined by the relative positions of the frame 10 and the crawler track unit 17.

Extending outwardly from frame 10 along the augers 15 yare front and rear parallel :arm )assemblies 20, 21. Each assembly `of parallel arms includes both upper and lower arms pivoted vat their respective ends to the frame 10 and to the conventional crawler track unit 17. Therefore, the .angle of the crawler track units 17 will remain constant relative to the frame 10 due to the connection of these parallelogram arms. For stability, it will be noted that the parallel arm `assemblies 20, 2-1 diverge outwardly from the frame 10 (FIGURE 3).

The 4relative positions of the crawler track unit 17 and frame 10 are controlled by means of powered extensible elements extending outwardly from the apex of the triangular braces 12 to the crawler track'units 17. These extensible units include two telescoping rigid elements. An inner member 22 is pivotally connected `at its outer end to the crawler track unit 17. An outer member 23 is pivotally connected at its inner end to the triangular braces 12. The inner member 22 is -free to move longitudinally relative to the outer member 23.

The relative positions of the members 22 and 23 can be controlled in any desired manner. VAs an illustration, a simple winch assembly is shown. This includes a pair of pulleys 25 mounted on a center shaft 24 at the top of the triangular braces 12. Each pulley 25 has a cable 26 passing over it and about a guide pulley 27 at the outer end of the member 23. The cable 2-6 is anchored at its outer end to the inner end of the member 22, inside the member 23'. The remaining end of the cable 26 is wrapped :about a winch assembly shown generally as 30.

It can be seen that when the cables 26 are pulled by the Winches 30, the inner members 22 wil-l be forced outwardly of the outer member 23, and the extensible elements will therefore cause the arms 20, 21 to lift the .frame 10 relative to the crawler track units 17 as seen in FIGURE 2. Likewise, when cables 26 are played out from Winches 30, the weight of the frame 10 will cause the frame 10 to be lowered relative to the crawler track units 1'7 to attain the position shown in FIGURE 1, or whatever position might be required due to the particular canal cross-sectional configuration.

For illustrative purposes, a pair of short feed conveyors 31 are shown leadin-g from the digging wheel assemblies 14 to the rear central portion of the machine. These :onveyors feed to a discharge conveyor 32 that extends upwardly along one side of the machine .and beyond the adjacent -crawler track unit 17. As illustrated, the frame l carries an engine 33 for the various pumps and motors involved in the particular apparatus. A control panel 34 is provided with a platform for use of an operator. The apparatus as illustrated has a low center of gravity on the frame as contrasted with rigid trames for similar operations which normally have a center of gravity quite high relative to the bottom of the canal ditch.

The present invention provides a very simple mechanical arrangement for supporting the surfacing equipment necessary to finish a trapezoidal canal cross-section in one pass. It is to be noted that the apparatus illustrated could be used on canals of differing cross-sectional configuration wherein the side slopes have different angles relative to the horizontal. The machine is capable of lifting itself from the ditch so that it can move about obstructions such as bridges and so that it can move from one work area lto another without the necessity of external equipment to carry it. Due to this, the machine can be vrnade for use on canals having a greater crosssectional dimension than could be accommodated by a conventional rigid frame apparatus. The improved versatility and adaptability of this machine make it extremely useful in this type of construction.

Various modications might be made in the basic structure illustrated without deviating from the concept included in it. For these reasons, only the following claims are intended to limit the scope of the invention.
