Title: Improvements in or relating to ploughs
IPC: A01B61/04
Filed: 1966-01-11
Abstract: 1,141,701. Agricultural implements. G. C. KNUDSON. 11 Jan., 1966, No. 1239/66. Heading A1B. A tractor drawn plough comprises a main cylinder the piston rod of which is acted upon by one or more compression springs, the main cylinder being operatively connected to a plurality of plough body cylinders, and a plurality of plough bodies mounted on standards which are pivotally connected to the plough frame, each body being held in its operative position by fluid under pressure in its associated cylinder which is pivotally attached both to the standard and the frame. Upon encountering an obstacle a plough body is pivoted about axis 75 (Fig. 3) to an inoperative position and fluid in the associated cylinder is forced via a one-way valve 97<SP>1</SP> (Fig. 6) into a master cylinder 79 thus displacing piston rod 79<SP>1</SP> against springs 81, 82. When the obstacle is passed the action of the springs causes fluid to return to the associated cylinder to return the plough body to its operative position. The hydraulic system may be charged via valve 99 by fluid from the tractor's hydraulic system, and the pressure may be indicated by a pressure gauge. Plough supporting wheels (22, 23 and 45) (Fig. 1, not shown) which are interconnected by linkages are raised and lowered by a hydraulic cylinder (not shown). In alternative embodiments the piston rod 79<SP>1</SP> may be connected to a rod 83 via linkages, and the plough bodies may be pivotally connected to their standards and connected to their associated cylinders via linkages (Fig. 15, not shown). Reference has been directed by the Comptroller to Specifications 1,078,133 and 1,091,779.

Abstract: 1,221,413. Latches; locks. HUMPHREY & J. FOX & R. H. MORGAN Ltd. 12 Jan., 1968 [14 Jan., 1967], No. 2088/67. Heading E2A. A night latch comprises a bolt 11 which is movable by an operating handle 14 and by a key, through a lock, between a retracted position and a projected locking position and incorporates at its head a ball or roller 13 which when the bolt is in its retracted position projects under spring loading partly out of the latch housing 10, but can be pressed into the latch housing against the spring loading to enable the ball or roller to act as a catch for releasable engagement with the latch keeper, the latch further comprising a key operated element 36 which when the key is turned in the bolt-projecting direction to project the bolt, is moved by the 'key to permit the bolt; to be retracted by the handle when the key is removed from the lock, and which element, when the key is turned further in the same direction dead-looks the bolt in its projectable position if the key is removed from the lock, so that the bolt cannot be retracted by the handle. As shown the bolt is operable by the handle 14 through a crank 18 on which a pin 20 engages a hole 21 in a link 17 having a pin and slot connection 15, 16 with the bolt 11. An arcuate wall 22 surrounding the hole 21 acts as a connecting means and as an abutment for the element 36 which is carried by a hub 35 rotatable by a tongue 34 of a cylinder lock (not shown). The link 17 is loaded by a spring 24 and the bolt is loaded by a spring-loaded plunger 29. In use, the bolt is moveable to the locked or unlocked position by the handle 14 or by a key. In the latter case, rotation of the key beyond the position in which it moves the bolt to its locking position, moves the element 36 out of engagement with the interior of the wall 22 and into engagement with the exterior of the wall. Removal of the key then prevents retracting movement of the bolt by the handle 14.

[Also in Division E2] A hinge for infinitely varying the angle of inclination of the back of a seat has a pair of members 10, 11 pivoted together at 12 and is characterized by member 10 supporting a plate 20 having a helical guide 22 engageable with any of the projections 27-29 of the member 11. In the upright position (as shown in Fig. 1) projection 27 is engaged in guide 22, but to alter the angle of inclination of members 10, 11 shaft 21 is turned to rotate plate 20 thus moving projection 27 around the guide 22 until it reaches a position where projection 28 enters the beginning of the guide 22. On further rotation, projection 29 enters the guide 22. In any position, the members automatically lock together since the angle of the helix with respect to the normal radius vector is less than the angle of friction. A spring may be provided to facilitate return of member 11 to its initial position.
