  • FIG. 7 is a partial front view, showing a particular position of the excavator, while digging trenches.
  • the excavator 10 comprises a stationary frame 11, mounted on tracks 12 and 13 for its motion, and carrying on its top a turntable 14, revolvingly fitted on its vertical axis, and whereon the proper excavator is fitted.
  • the excavator section consists of a boom 15, that is operated by the driving cylinder-piston aggregates 16 and 17 of the motor 18, and of the drivers cab 19, wherein the control levers 20, operated by the driver, are fitted.
  • the stationary frame is connected with the tracks 12, 13 through pairs of connecting rods 21, 22 and 23, 24, by which articulated parallelograms are formed, and that are driven by the cylinderpiston sets 25, 26. Fitted on the same frame, is the stationary component 27 of a ball-joint linkage 28, that is controlled by the jacks 29, 30.
  • the frame 11 is supported by four pairs of connecting rods on each side thereof, and each set formed by two pairs of close-fitted connecting rods-ie., two articulated parallelograms-is driven by one of jacks 25, 26, while the ball-joint linkage 28 is preferably controlled by four jacks 29, 30, 31 and 32, respectively pivoted on the stationary frame, and on a central component 33, fastened to movable component of ball-joint linkage, being sarne jacks fitted with suitable cardan joints or the like, allowing also a side motion thereof.
  • the bucket boom 15 is not connected to the excavator body on a fixed pivot point, being conversely pivotally connected, along with the related driving cylinder-piston set 16, with a plate 35, that can be turned on its pivot point 36.
  • the boom 15 can be swiveled both on its own pivot point 37 and on the pivot point 36, while the related hydraulic cylinder 16 can also be swiveled on both pivot points 38 and 36, thereby obtaining a wider range of bucket motions, either vertically and horizontally, according to the positions taken by the plate 35, that can be moved by means of jack 40, which is connected on one end with a fixed pivot point on the excavator frame, and on the opposite end with the same pivot point 37 of boom 15.
  • jack 40 which is connected on one end with a fixed pivot point on the excavator frame, and on the opposite end with the same pivot point 37 of boom 15.
  • a and a' are the two positions which can be attained by the bucket, when the pivot point 37 of boom 15 is in its upper position 37', and consequently the pivot point 38 of driving cylinderpiston set is in its position 38'
  • b and b respectively are the positions that can be attained by the bucket, when the pivot points 37 and 38 are both in their lowest position, as shown in the drawing with solid lines
  • c and c are the end positions that can be respectively attained in the longitudinal directions, when the pivot points are in their lifted and lowered positions.
  • Such device consists of a ball-joint linkage, made up substantially of two components, i.e., a stationary component 27, consisting of two separable sections 41, 42, to allow the assembling of movable component 28, which is then retained in its position, in such a manner as to be able to turn in any direction round the point 43.
  • the fixed component 27 and the movable component 28 mutually contact on a spherical surface, obtained ⁇ by cutting a sphere along two planes parallel with each other, and with the equatorial plane, and extending on either sides of latter plane, being such planes respectively indicated by numerals 44 and 45 on the movable component, and by numerals 46 and 47 on the stationary component.
  • FIG. 6 The device by which the excavator tread can be changed, and of which a brief mention has already been made in the description referred to FIG. l, is shown in FIG. 6.
  • Such change is obtained by having the frame 11 connected with the tracks 12 and 13 by means of articulated parallelograms, consisting each of two pairs of connecting rods 21, 22 and 23, 24, respectively connected with the frame in the pivot points 51, 52 and 53, 54, and with the tracks in the pivot points 55, 56 and 5-7, 58.
  • a pneumatically or otherwise driven jack is fitted along a diagonal of each articulated parallelogram, and is connected therewith, e.g. in the pivot points 51, 56 and 53, 58, thus allowing to extend or to restrict said parallelogram, whereby the related track is drawn away from, or brought closer to the frame.
  • the excavator tread can be changed at will, but also the distance between the frame axis and the axis of a single track can also be modified, when required by particular conditions.
  • the above system in addition to the abovestated advantages, concerning the road transport of excavator, and the possibility to have very wide trenches dug, since the widening and restricting of tread respectively result in a lowering and lifting of frame, further advantages can be obtained, increasing both the depth of excavation and the height of discharge.
  • the excavator frame 11 can be lowered until it comes to rest on the ground, thereby preventing all shocks and jerks, to which an excavator is usually submitted while operating, from being transmitted to not very rugged tracks and other drive mechanisms of the machine.
  • FIG. 6 12 and 13 are the positions of tracks at which the smallest tread is obtained, whereby the frame 11 is lifted at the most from the ground, being such positions coincident with those of FIG. 1.
  • FIG. 7 A particular advantage of the abovedescribed arrangement is clearly shown in FIG. 7; the excavator illustrated therein is set to work on a trench 59, which banks 60, 61, while being parallel with each other, are however stepped down by a depth h.
  • the jacks 25 and 26 have been operated in such a manner as to close the parallelograms formed by the connecting rods 21 and 22 and to conveniently extend the parallelogram formed by the connecting rods; thus, both tracks are positioned at level with the ground and wholly adherent therewith, while Yon the other side the frame 11 is adjusted on a perfectly horizontal position, which can be controlled by an expressly provided level indicator, fitted in the drivers cab, which may be the Same instrument by which the movements of ball-joint linkage are controlled, or can ybe independent therefrom.
  • a sleeve or the like can be possibly interposed 'between the frame 11 and the turntable 14 thus -bringing this latter at a higher level, in order to prevent the movable assembly from striking, while being rotated, a lifted track.
  • An excavator comprising a chassis, a supporting frame on said chassis, an endless track adjustably secured at each of the sides of said frame, a body, an excavator boom supported by said body, a turntable for said body mounted for rotation about a substantially vertical axis, a 'tiltable component fixed to said turntable tiltably supported on said frame, link means connecting each endless track to a side of said frame, a first actuator means connected to said frame and tracks for individual positioning of said tracks relative to said frame, said tiltable component comprising a member having a first spherical zone between two parallel planes symmetrically spaced from the great circle of a sphere, a component fixed to said frame having a second spherical Zone concentric to and mating and frictionally engaged with said first spherical zone, whereby said tiltable component and said body and boom assembly supported thereby can be rotated in any direction about the common center of said spherical zones, and a second actuator means connected to said frame and to said tiltable component to control the
  • link means comprise pairs of parallel links each having their ends pivotally connected to said frame and to one of said tracks to form articulated parallelograms and said first actuator means comprises jacks connected along diagonals of said parallelograms.
