Abstract

1437231 Valves; linkwork CATERPILLAR TRACTOR CO 17 July 1973 [17 Aug 1972] 33999/73 Headings F2V and F2K In a valve arrangement for a loader bucket three separate valves are controlled by two levers 12, 26 which are disposed so that they can be operated by a single hand. When lever 12 is rotated about the axis Y on pivot 14, rod 15 is reciprocated and operates valve 19 via bellcrank 16. Operation of lever 12 in a plane at right angles to the plane of the previously described movement rotates a tubular bellcrank 20 through an arm 21 and a further arm 22 operates valve 24. A second lever 26, pivoted about an axis Y<SP>1</SP>, produces no effect when rotated about this axis, but when rotated in a plane at right angles to this movement operates a third valve 34 via a lever 31. The control levers may be locked in their neutral position by means of a hinged slotted plate 35 which engages lugs 40, (41) on the arms 12, 26. A hole 42 is provided for a padlock. The lever 26 is provided with rubber friction bushes (46) at its pivot to hold it in a selected position.
