Definitions

  • This invention relates to a device intimately associated with all tools such as spades, shovels, forks and any tool of this kind, or operated in a similar way.
  • An object of the invention is to make the handling easier and less tiring, to increase efficiency by bringing in additional points of application for extra mechanical efiorts.
  • the tools cooperate with a working support to which, in accordance with this invention, the handle is connected in a flexible way by any direct or indirect form of link-up whatever and/or any method of suspension, and/or any support with at least one connecting part or flexible attachment.
  • the path followed by the tool is not a mere rotation around a single central point but is rather an intricate kind of motion following the action of the worker's body and arms, a motion that involves several turning movements around several simultaneous fixed or moving centers.
  • the clod When digging, according to the invention, the clod is thrown forwards and upwards by centrifugal force.
  • the various points of the clod differ in speed according to their turning radius, so that the lump of earth turns over in the air and falls back on the previous one with its upper portion resting in the bottom of the furrow.
  • the handle of the tool is pivoted on an intermediate point of a working support, while it is hung in a flexible way to the upper part of the support, the lower portion of which rests on the ground.
  • the upper end of the handle is provided with a single cross-piece with or without handholds or with a handle-bar with or without a damping device, so that the tool by means of this single handle, may be operated at the same time and in the same way by both arms, thus bringing to this type of adaptation an altogether new technique.
  • the improvements, that form the object of this invention may be carried into efiect under very varied structural forms according to the shape and size of the combined kinematic parts, as well as to the various combinations that may be made between such parts.
  • Applicant has experimented with various structural forms and has succeeded in giving 60 strokes per minute with a spade in sandy soil, and practically, in average soil and for work lasting some time, 3:) to 45 strokes per minute.
  • Figure 1 is a side view and Figure 2 a front view of an improved tool in accordance with the invention. 7
  • Figure 3 shows the apparatus at ning of the working cycle.
  • the begin- Figure 4 shows the start of an opening furrow by successive clods of earth cut out deeper and deeper.
  • Figure 5 shows the beginning of a plot of ground, in which the earth dug up in the first furrow is thrown at right angles to the sides, the apparatus making this a very simple performance and the following furrows being dug then in the normal way.
  • Figure 6 illustrates a lateral tilting motion obtained through the rotation of the tool in the plane of the handle and round its axis, under the action of the two hands pressing on a single cross-piece or on the grip of the handle bar.
  • Figures 1 and 2 are shown at l the spade blade, at 2 the single handle, at 3, the single cross-piece or handle-bar, at 4 and 5, fixed or rotary handholds, at 6, the bracket attached to the handle at a point of its length, at 1, the bearing fastened on the bracket, at 8, a stationary or movable spindle passing through the bearing and projecting beyond it on both sides.
  • 9 and Hi designate the flanges of the working support, H and I2 the cross-pieces between said flanges, It the lower shoe connected to the support flanges 9 and l6, M a spindle passing through the support flanges at their upper end, 5 a grooved pulley set on the spindle l4 between the support flanges, I6 torsional coil springs, the tension of which can be adjusted by the length of the wires I l and I8, 17 wires connected with one end of the spring 16 by running in the pulley groove l5 and secured to the handle at Ila, 18 wires connecting the other end of spring 16 to the upper part of the handle at i8a, IS, an elastic stop fastened on the handle and damping the return bump and fixing the position of the support when inoperative.
  • 20 denotes the elongated holes or slots in the support flanges 9 and I0 and taking both ends of spindle 8.
  • Figure 3 shows the starting position with the working support at a certain distance from the ground.
  • the spade blade is dug into the ground and the shoe i3 is resting on the ground.
  • a second position of the tool is outlined in dotted lines after it has cut out a slice of ground.
  • This sharp stop allows the clod of earth to leave the blade i, through centrifugal action and to continue along the curved path defined by a combination of centrifugal force with the weight of the clod.
  • the lower portion of the slice of earth has a greater speed than the upper part of the spadeful of earth turns over in its travel through the air and falls back into the furrow with thehead part down.
  • the clod also may be pitched in an oblique oreven in a right-angle direction in relation to the plane in which theoperation of digging in the spade is performed; it issuiiicient towork with both hands on the handlebar and give at a simultaneous turningaround the axis of the handle.
  • This entirely new arrangement allows a simultaneous novel working method for both arms, that may then exert in a normal way a maximum effort without it being necessary to twist the body;
  • the apparatus is a simple structure and it is designed to the best advantage.
  • Figures 7, 8 and 9' illustrate intotal or in part the arrangements of Figures' I and 2' in a specially satisfactory form of adaptation; These figures V aim at showing more particularly the flexible link between the tool and the working support.
  • Figure '7 shows by” means of' a general arrangement that the working support inclines always to sawing forwardunder the action of working stresses that must necessarily”. have the d-irec-- tion marked by the arrow Fi
  • the strain Fis transferred to F on the spindleA and maybe decomposed into a strain T irr the support flangesand a strain'N at right'angles' to the latter.
