Title: Sailing boat rig
IPC: B63H9/10
Filed: 1958-05-23
Abstract: 847,310. Sailing boat rig. BOWDEN, C. E. May 11, 1959 [May 23, 1958], No. 16740/58. Class 115. In a sailing boat rig the mast 4, 7 and 8 is mounted in the hull so as to be capable of pivotal movement about a vertical axis and the upper part is split into two members 7 and 8 which are joined at 9 to form a slot through which the sail 13 extends. A boom 10, joined to the mast so as to be capable of movement with it, has a gaff 12 rigidly connected at 11 and adapted to fold flat on to the boom 10 with the sail 13, supported therebetween. The sail is provided with a series of battens 14 extending from a point adjacent the hinge 11 to spaced points along the leech. The sail 13 is raised and lowered by a halyard 17 joined to the gaff and passing over sheaves, at the mast head and forward end of the boom, to a cleat on the mast. The mast may be hinged adjacent the point where it splits into two members so as to be foldable on to the boom with the sail. In this case the top of the mast is adapted to move along the gaff by a runner engaging a track on the upper end of the gaff.

A milking apparatus includes a collector comprising a variable vacuum chamber 1 connected both to a pulsator 14 and the variable vacuum chambers 13 of the teat cups 12, a collecting chamber 2 connected to the teat chambers 10 of the cups, and a constant vacuum chamber 3 connected to the collecting chamber 2 when milk is being drawn from the teat cups and having a diaphragm 4 with a pipe 6 centrally attached which simultaneously disconnects the collecting chamber from the constant vacuum chamber and connects the former to the atmosphere so that the collector may be emptied. With the pulsator in the vacuum mode there is a reduced pressure in the variable pressure chamber 1 and the diaphragm 4 is in a raised position so that tube 6 engages a stopper 7. When in the non-vacuum mode, the diaphragm 4 is forced down to its lowest position where it engages the rim of opening 5 thereby disconnecting the chambers 2 and 3 and simultaneously the separation of the tube 6 from the stopper 7 allows the entry of air into the collecting chamber. The apparatus can be used for three cycle mode of operation when the bore of pipe 6 is enlarged and the compression stroke is followed by a rest stroke during which air in the teat chambers 10 is at atmospheric pressure.
