ROBERT SCOTT, OF HONOLULU, TERRITORY OF HAWAII.

MACHINE FOR CONVEYING AND LOADING CROPS OR MERCHANDISE.

SPECIFICATION forming part of Letters Patent No. 718,732, dated January 20, 1903.

Application filed February 8, 1902. Serial No. 93,200. (No model.)

To all whom, it may concern:

Be it known that I, ROBERT SCOTT, a citizen of the United States, residing at Honolulu, Island of Oahu, Territory of Hawaii, have invented certain new and useful Improvements in Machines for Conveying and Loading Crops or Merchandise; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is designed principally for use in sugar-cane fields, and it is intended to receive the sugar-cane as it is cut by the laborers and convey it to a carlocated near the machine.

The object of my invention is to produce a simple,inexpensive,portable, easily-operated labor-saving machine. I employ either two or four arms pivoted at the center, capable of being moved in a horizontal plane about their common pivot. Each pair of arms is rigidly connected together at the center of the machine and braced, so as to be in line with each other. When four arms are used, the pairs of arms are placed at right angles to each other. Each pair of arms is capable of being moved in a vertical plane, like a seesaw, independent of the other pair. The pivot is supported either by an adjustable tripod or other suitable arrangement upon the ground, and the machine, which is light, is carried by hand from one position in the field to another when necessary, or the machine may be located on a car or wagon. Attached to the arms is a track carrying a trolley that is capable of being moved in or out along the arm toward or from the pivot of the machine. The cane to be loaded is first cut and then laid upon slings placed upon the ground or on a cradle. The ends of a loaded sling are then attached to the trolley by depressing the arm of the machine brought over the sling. A man at the opposite arm then depresses his arm, thereby raising the sling loaded with cane, which becomes suspended on the trolley of the arm opposite the operator. The machine is then turned, if neces sary, and the sling is moved in or out on its trolley-track until it is over the car to be loaded. The cane is then dropped into the car, as will hereinafter more fully appear.

In the accompanying drawings, Figure 1 represents an elevation of one-half of a twosmaller scale, a plan of the arms of a fourarm machine with the horizontal bob-stays. Fig. 3 shows, on a larger scale, the swinging joint of a four-arm machine. Fig. 4: represents, in elevation and part section, the joint at the center of the first pair of arms and the pivot arrangement. Fig. 5 represents the method of connecting the pipes forming the arm.

Similar letters of reference indicate similar parts throughout the several views.

Referring to the drawings, it will be noted that the machine as a whole is of light but strong construction.

The arm A, Fig. 1, is preferably made up of different sizes of pipe a a a telescoping each other. One of these joints is shown in Fig. 5. A split collar 10' is secured inside the pipe a, and is tapered inside to receive the end of the pipe a While another split collar 20 fitting the pipe (1 is tapered outside to wedge the end of the pipe at. Collars b b are clamped at the joints and are provided with a boss to secure the struts c 0 Fig. 1, to the overhead or vertical bob-stay d. The largest-size pipe at at the center of the ma chine is in one piece and is common to both arms A and B and has a hole through its center, through which the pivot f is free to 0perate. The trolley-track g g is secured to the arms at intervals, and a connecting-piece g may be used to connect the tracks 9 and g together when desired to run the trolley from one arm to its mate. It will be understood that it is necessary that the pivot be located at a suitable height from the ground. As shown more fully in Fig. l the pivot referred to consists of a continuation of the end of the pin f, which continuation passes through a supporting-hanger g said hanger being held in place by nuts screwed upon the screw-threaded end of the continuation of the pin f. The continuation of the pin f passes through an aperture in the hanger and permits the hanger to swing horizontally to the extent permitted by the legs of thetripod through which it passes. The connectingpiece 9 is likewise adapted to swing vertically or tilt upon the hanger g as a center. At the outer ends of the connecting-piece g are attached the spring-stops 9 having at their upper ends the rounded portions g which are adapted to catch under or engage with the under side of the pipe (1, so that the connecting-piece will rock with the arms A B and with the tracks 61 d. When the armsA B are moved in a horizontal plane, the connecting-piece 9 will travel with them until it comes in contact with the obstructing leg of the tripod, whereupon the spring-pieces 9 will release their hold upon the pipe at. The operator applies his weight to a stirrup h, which is adjustably suspended from a wheel j on the outer end of the arm, and he may use different lever-arms by shifting the position of the wheelj by the use of the rope 70, passing through the blocks 7; k or he may operate it simply by a rope attached to the end of the arm, or, as illustrated in dotted lines in Fig. 1, the stirrup and its operating mechanism may be located upon the track instead of being located upon the arm above it.

\Vhen four arms are used, the arms 0 and D, Fig. 2, are securely fastened to castings Z 1*, (shown in Fig. 3,) which are bolted together over arms A and B and straddle the casting m at the center of the machine. \Vhile l and Z are bolted together tightly, they do not tightly grip the pipe at of arms A and B, but permit the arms 0 and D to move in a vertical plane about the axis of the pipe a. The castings Z and Z may be provided with roller-bearings and the pipe a provided with wearing-bushings. A boss is provided on Z and Z (shown at n and n in Fig. 3,) each to carry a pipe-strut, these two struts being slightly longer than the center strut 0', attached to m, in order that the vertical bob-stays may clear each other. Side bob-stays are shown in Fig. 2, the inner ends being fastened to clips 7" r for arms A B and to the castings Z l at 1) p 6150., for arms 0 and D, as shown in Fig. 3.

In order to bring the center of gravity of the machine below the point of suspension, a casting m, Fig. 4, in the form of a cross is used. This fits snugly over pipe a, and has a cap q screwed into its upper branch. The strutpipe 0 is screwed into this cap and a hardened-steelcuprissecured underneath. The upper end of the steel pinf is rounded and hardened and fits the cup 9'. This pinfis tapered near its lower end to fit the tripodhead. The lower branch of the cross m is partly filled with metal, (shown in section, Fig. 4,) so as to leave an oblong opening for the pin f and allow the arms A and B to tip only in a vertical plane. The hearing may be made dust-proof by employing a felt or other suitable washer, as shown in Fig. 4. This opening may be provided with rollerbearings. A drum or winch arrangement may be attached to the tripod and a snatchblock attached to the arm in place of the trolley arrangement for lifting the loaded slings.

To facilitate operations, I preferably employ a detachable sling-as shown, for instance, in Fig. 1-which may be made in two parts which are easily coupled or uncoupled. This sling is laid upon the ground or on a cradle and the cane is piled upon it-say a hundred pounds for a load. After receiving the load it is placed over the hook g of the trolley, and by the operation of the machine already described the loaded sling is brought over the car to be loaded and the cane is discharged.

The arms in practice are each made about thirty feetlong. Two machines may be placed with pivots about sixty-one feet apart and connected together by a short piece of pipe slipped into the pipes forming the outerends of one arm of each machine, and with a short rail connecting the trolleys the load can be shifted from one machine to the other. As indicated in Fig. 1", the lower end of the pin fmay screw into a pipe-stand suitably anchored in place, so as to sustain the weight of the machine, in lieu of a tripod. Moreover, the lower or pointed ends of the tripod may serve as pistons to the upper portions thereof, and the cross-pipes a or b, or both, may constitute reservoirs of compressed air in Whole or in part, which air may be admitted into the hollow legs of the tripod simultaneously by means of the branch tube 00, (shown in Fig. 1,) adapted to connect with the nipples shown upon the tripod-legs. By admitting compressed air into the legs of the tripod the upper part of said tripod will be lifted to raise the beam to any desired height, and by permitting the air to escape from the tripod-legs the tripod will be lowered correspondingly. By this means the beam carried by the tripod may be adjusted to such heights as the operator may find necessary.

Aspring-catch'y (see Fig. 1) may be clamped upon the track at any desired point, so as to permit the trolley to pass over it in one direction, but which will not permit it to return until removed or depressed for that purpose.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
