Title: Improvements in and connected with change speed gearing
IPC: F16H3/091
Filed: 1940-06-05
Abstract: 544,129. Variable-speed gearing. DAIMLER-BENZ AKT.-GES. June 5, 1940, Nos. 9855, 9856 and 9857. Convention dates, May 13, 1939, Aug. 9, 1939 and Aug. 14, 1939. [Class 80 (ii)] In a variable-speed gear the direct drive and a lower gear ratio are selectively connected to the driving shaft a by a synchronizing clutch u, and the other forward speeds are obtained through gear wheels m, o, q fixed to the driven shaft b in constant mesh with gear wheels l, n, p free on a countershaft c and selectively coupled thereto by synchronizing means v, w, on the countershaft c. The construction shown gives five forward speeds and a reverse, the fifth speed which takes place through the gears p, q, upon operation of the clutch w, being an overdrive. The synchronizing clutches are of the type 'comprising friction clutch and dog clutch parts splined together and held together by a ball catch. The reverse speed is obtained by sliding a gear s on an auxiliary shaft d into engagement with a gear r on the countershaft .c and a gear t integral with the outer sleeve u<SP>2</SP> of the synchronizing clutch u. The different speeds are brought into action by axial sliding of selector bars x .. x<SP>4</SP>, each of which may be engaged by a hand lever e capable of longitudinal and transverse movements. The selector bar x<SP>1</SP> actuates the reverse pinion s, x<SP>2</SP> the clutch v for the first and second speeds, x<SP>3</SP> the clutch u for the fourth (direct) and third speeds, and x<SP>4</SP> the clutch w for the fifth speed (overdrive). To assist the driver when gear changing the actuating hand lever e is arranged during its transverse movements to encounter different degrees of spring resistance when going into reverse and when going into and out of the overdrive, the former resistance being the greater. The lever e has a portion 15 engaging a slot 16 in a plate 12 guided at 13, 14 for sliding movement only in a transverse direction. One edge of the plate 12 has inclines 30, 31 engageable with a spring stop 20, and the opposite edge of the plate can engage a spring stop 19, the stops 18, 19 being mutually perpendicular. The stop 18 is for the overdrive, and the stop 19 is for the reverse.

Title: Milking apparatus provided with collecting unit
Inventor: WILMERING
IPC: A01J5/04
Filed: 1985-04-29
Abstract: The invention relates to a milking machine with a milking tool which consists of teat cups and a collecting piece and which is connected via a milk pipe to a milk-conveying line, the inside of the collecting piece being supplied with atmospheric air in the relief phases. The atmospheric air forces the milk through the milk pipe into the milk-conveying line. In the milking phases, the inside of the collecting piece is then once again connected immediately via the connection pipe to the vacuum of the milk-conveying line, the air line or flushing line. The quantity of milk situated in the milk pipe therefore has no effect on the vacuum level inside the teat cups. The vacuum inside the milk-collecting piece is controlled via a two-way membrane valve switched by the milking pulsator. <IMAGE>
