JOHN H. N. WILSON, OF HONOLULU, TERRITORY OF HAWAII.

SPECIFICATION forming part of Letters Patent No. 747,027, dated December 15, 1.903.

Application filed March 30; 1903.

To (tZZ whom itmtty concern.-

Be it known that I, JOHN H. N. WILSON, a citizen of the United States, residing at Honolulu,in the Territory of Hawaii, have invented a certain new and usefulImproved Apparatus for Cutting Sugar-Cane or the Like, of which the following is a specification.

This invention relates to an improved apparatus for cutting sugar-cane, which has a plurality of cutting devices operatively arranged between two cars or vehicles separated a certain distanceand adapted to traverse a field; and the object of the invention is to cut sugar-cane or other vegetation in a rapid, efficient, and economical manner.

The invention also relates to certain details of construction, all of which will be fully and clearly hereinafter described and claimed,reference being had to the accompanying drawings, in which- Figure 1 is an end elevation of the improved apparatus. Fig. 2 is a side elevation of one of the cars. Fig. is a top plan View of one of the cars. Fig. 4 is an enlarged fragmentary side view illustrating the ropetightening device. Fig. 5 is an enlarged fragmentary edge view illustrating'the ropetightening device. Fig. 6 is an enlarged fragmentary view showing the supportingrope, the main air-conducting tube, one of the air-tubes, and the three-pulley device and the pulley-weight in their proper rela tion. Fig. 7 is an enlarged detached view of the three-pulley device. Fig. 8 is an enlarged detached view of the pulley-weight. Fig. 9 is an end elevation of a car having a modified form of frame or'support for the cable and air-supplytube. Fig. 10 is a side elevation of the frame shown in Fig. 9, also showing a fragment of the car. Fig. 11 is an enlarged fragmentary view of the lower end of one of the vertical beams. Fig. 12 is an enlarged fragmentary section through the beam and spud, showing the rack and pinion. Fig. 13 is an enlarged inside view of the upper end of the spud, showing the rack-bar.

In referring to the drawings in detail like numerals designate like parts.

The apparatus consists of two cars which are mounted upon rails separated from and extending substantially parallel with each other, a supporting rope or'cable extending securely bolted together.

Serial No. 150,165. (No model.)

compressor on the car or cars.

The rails 1 are of any suitable form and are laid across the field upon which the sugar cane or other vegetation to be cut is located on suitable ties 2 or other supporting means. The pairs of rails are separated sufficiently to leave between them quite a tract of the field and extend substantially parallel with each other, as shown in Fig. 1.

The cars 3 are preferably of the kind known as flat-cars and are provided with the usual trucks 4, wheels 5,-and platform 6, upon which the apparatus is mounted. A plurality of beams 7 are fastened transversely to the platform 6 at about the middle thereof, and upright front frame members 8 and diagonallyextending rear frame members 9 are supported upon the beams 7, the members 8 and 9 being fastened at their lower ends to longitudinal frame members 10 and 11 and at their upper ends to longitudinally-extending beams 12 and transverse beams 13, the whole being (See Figs. 1 and 2.) Transverse beams 14 extendbetween the frame members 8 and 9 at about the middle thereof, and a platform 15 is supported upon the beams 14. The frame is additionally braced by longitudinally-extending beams 16, mounted upon the platform 15. Two transversely-extending beams 17 are supported upon the longitudinal beams 12 and are securely fastenedin place by brackets bolted to the

beams

12 and 17. Asheave 18is mounted upon a short shaft 19, which is journaled in bearings 20, fastened to the top of the beams 17, and a rope or cable 21 passes over the sheave 18 and has one end coiled or Wound upon a spool or Windlass 22, mounted upon a shaft 23. The opposite end of the cable 21 crosses the field and passes over a similar sheave 18, mounted upon the frame of the second car, being fastened in place substantially as above described. The shaft 23 is journaled in bearings 24, fastened to the rear of the frame members 9, and carries a spur gear-wheel 25 upon one end. A shaft 26 is journaled in bearings 27, fastened to the frame members 9 above the bearings 24, and

. has a pinion 28 mounted on one end, which meshes with the gear-wheel on the shaft 23. The shaft 26 is provided with a crank or handle 29, by means of which it is rotated, and a ratchet-wheel 30 is mounted on the shaft 26. A pawl 31 is supported on the side of one of the frame members 9 and engages with the teeth on the ratchet-Wheel 30, thereby preventing the rotation of the shaft 26 in one direction. The object of the Windlass is to take up any slack in the supporting-cable by winding sufficient of the cable thereon to regulate its length to correspond to the distance between the cars.

The apparatus for supplyingthe compressed air to operate the cutting devices comprises an air-pump 32, which is connected to an oil or gasolene engine 33 by a belt 34, passing around pulleys 35 and 36, mounted on the shafts of the pump 32 and engine 33. The compressed air is conducted from the airpump 32 to an air-tank 37 by a pipe 38, and a flexible air hose or tube 39 has one end connected to the tank 37 and is then coiled upon the platform 15. A series of pulleys 'or sheaves 40 are supported upon the cable 21, each of which is provided with side plates 41, between which the pulley 40 is pivoted, and a pulley or sheave 42 for supporting the air-supply tube 39 is mounted between the plates 41 and below each of the sheaves 40. The air-supply tube 39 passes over a pulley 43, supported from brackets 44, fastened to one of the longitudinal beams 12, and extends across the field to the other car, being supportedupon the pulleys or sheaves 42. I term the

pulleys

40 and 42, together with their supporting-plates 41, the double-pulley devices. A number of the side plates 41 are made longer and support a third or lower sheave 45, over which the air-tubes 46, supplying air to each of the cutting devices 47, pass. Each of the tubes 46 has one end connected to the main air-supply tube 39 by a coupling 48, and its opposite end is connected to one of the cutting devices 47. A pulley or sheave 49, provided with a balancingweight 50, is supported on the tube or hose 46, between the coupling 48 and sheave 45, and serves to take up any slack in the tube 46 which may be caused by the unevenness of the field.

For supplying the engine 33 with oil or gasolene each of the cars 3 is provided with'a gasolene or oil tank 51, which is connected to the engine 33 by a line of pipe 52, (see Fig. 3,) and a water-tank 53 is also connected to the engine 33 by a pipe 54 to supply water for cooling the engine. The main air-tube 39 is provided with a valve 55, near each tank 37, for regulating the air-supply.

The preferred form of cutting device employed is shown and described in my Patent No. 706,481, granted August 5, 1902, to which winding a portion of the cable from the windlass 22 and uncoiling a portion of the air-tube 39 from the platform 15, or the slack may be taken up by winding the cable upon the windlass 22 and coiling the tube 39 upon the platform 15.

Figs. 9 to 13, inclusive, show a modified form of frame for supporting the cable 21, and air-supply tube 39, which is adapted to be used when the cable 21 crosses a large tract of field, and is so constructed as to relieve the car from any strain from the weight of the cable 21 and air-supply tube 39.

In the construction shown in the drawings a series of beams 56, preferably four in number, are mounted upon the platform 6 of the car 3 and extend upwardly and inwardly, the upper ends being fastened to

blocks

57 and 58. Transversely-extending beams 59 are mounted upon the platform 6 of the car, and the lower ends of the beams 56 are fastened to the ends of the beams 59. The frame is additionally strengthened by longitudinallyextending beams 60, which are fastened to the beams 56 and 59.

A spud or pile 61 is adjustably fastened to the lower extremity of each of the beams 56 by metal straps or guide-plates 62, which are rigidly secured to the beam 56. Each of the spuds or piles 61 has its lower end pointed, asshown in Figs. 9 and 10, and is provided on its inner face with a rack-bar 63, seated in a depression 64, and a pinion 65, mounted upon a shaft 66, is seated in an opening 67 in the beam 56 and meshes with the teeth of the rack-bar 63, by which the spud or pile 61 may be raised or lowered. The shaft 66 is provided with an operating-handle 68 and ratchet 69. A pawl 70, fastened to the beam 56, engages with the teeth on the ratchet 69 and prevents the backward rotation of the shaft 66. Longitudinal and transverse beams 71 and 72 are fastened to the beams 56 at about the middle thereof and support a platform 73, upon which the air-supply tube 39 may be coiled. Vertically-extending beams 74 are fastened to the beams and 71 and serve to support the drum 22. When the car has been moved to the desired position, the spuds or piles 61 are forced into the ground by means of the pinion and rack-bar 63, thus relieving the car of any strain due to the weight or winding up of the cable 21 and air-supply tube 39.
