Definitions

  • ABSTRACT OF THE DISCLOSURE A tractor mounted loader bucket designed for increased capacity, better balance, improved loading, and load distribution as compared to standard buckets and having in particular a bucket which has re-entrant chambers in its rear wall to enable forward positioning of the bucket lift arms, and a central portion extending rearwardly between the lift arms.
  • FIG. 1 is a view in side elevation of a tractor mounted loader with a bucket constructed in accordance with the present invention with parts broken away and with a bucket illustrated in full lines in its load position and in broken lines in its carry position;
  • FIG. 2 is a perspective view of the bucket of the present invention.
  • a conventional wheel type tractor is generally shown at as having a bucket, generally shown at 11, carried at its forward end on lift arms 12 which are pivoted to the bucket as at 14 while tilt linkage, generally indicated at 16, has pivotal connections with the bucket as indicated at 18.
  • Lift jacks not shown but of conventional form, are employed to raise the lift arms for elevating the bucket to the carry position shown in broken lines.
  • Tilt jacks one of which is shown at 19, are associated with the tilt linkage for swinging the bucket between load, carry and dump positions as the occasion requires, all in accordance with conventional practice.
  • a conventional bucket designed for use on the tractor and with the lift and tilt mechanism illustrated is of such a size that the pivots 14 and 18 are disposed just to the rear of the rear bucket wall.
  • the capacity of the bucket 11 has been increased by extending the central portion of the rear bucket wall rearwardly between the lift and tilt mechanisms as shown at 21.
  • the rear portion of the bucket adjacent its opposite ends has been extended rearwardly as illustrated at 22, thus increasing the capacity of the bucket materially and providing in effect what may be considered re-entrant chambers in the back of the bucket shown at 24 in FIG. 2 and each comprising spaced walls between which the pivotal connections 14 and 18 of the lift and tilt mechanisms extend.
  • the leading corners 23 of the re-entrant chambers 24 are chamfered for ease of entry of material into the rearwardly extending chambers.
  • the end portions 22 are of less depth than the central portion 21 in order to provide space for the front wheels of the tractor.
  • the forward walls of the re-entrant chambers occupy substantially the same position that is occupied by the rear wall of a standard bucket. Consequently, the rearwardly extending chambers at both ends of the bucket and centrally of the bucket represent a great part of the increased bucket capacity. This has been accomplished without changing the configuration of the lift and tilt mechanisms and without extending the cutting edge 26 of the bucket forwardly which would create an imbalance and an increased moment arm while the bucket was being raised. Furthermore, the forward extension of the cutting edge 26 would require greater breakout force which is necessary for racking the bucket backwardly after it is loaded and this would require bigger or more powerful tilt jacks 19.
