Title: Control lever assembly for power shift transmission and modulating clutch
IPC: B60W30/18
Filed: 1975-10-03
Abstract: 1511890 Change speed and clutch control FIAT-ALLIS CONSTRUCTION MACHINERY Inc 3 Oct 1975 [23 Oct 1974] 40588/75 Headings F2D and F2L On a crawler tractor a combined changespeed and clutch control lever 27 operates a speed-ratio and forward-neutral-reverse control valve 26 by turning a rock shaft 46, linked by a rock arm 53 to the shift valve 26, by transverse movement of the control lever 27 in a slot 80 in a V-shaped pivoted bracket 82, which is turned about a pivot axis 85, 86 when the control lever 27 is moved longitudinally to cause a pin 95 on the bracket 82 to traverse a cam slot 96 in a plate 97, thus rocking the said plate 97 about a pivot 100 to actuate, through linkage 115, a clutch, control valve 25 regulating the pressure applied to a modulating main clutch 17, to provide a further speed control of the tractor. Interlocked with the control lever 27 is a safety start lever 28 which can be moved to a forward position, shown, closing a switch 24 in the usual engine-start circuit only when the shift control lever 27 is in neutral, the latter being then locked in that setting until the safety lever 28 is moved rearwardly to the run position. From the neutral-start position, shown in Fig. 5, the combined shift and clutch lever 27 is shifted transversely to the right for ratios 1 and 2 forward, and leftwards for the same ratios in reverse, the bracket 82 remaining unaffected. In any ratio setting the lever 27 can be moved rearwardly to rock the bracket 82 producing progressively increased clutch engaging pressure at a rate determined by the shape of the cam slot 96. Rearward movement of the lever 27 in a central slot controls a power take-off by means not described. Rearward lever movement is opposed by a spring 91, and resistance to movement in both directions is produced by friction washers (125, Figs. 3 and 7, not shown), screw adjustably spring clamped to the bracket 82 at its pivot. Movement of the safety start lever 28 to the forward, start, position, shown, rocks a bracket 75 about a pivot 152 to close, through an adjustable bolt 174, the switch 24 in the enginestart circuit, such movement being possible only when, in the neutral setting of the ratio selector rockshaft 46, a pin 70 thereon can be received in a notch 74 in the bracket 75, and the shift lever 27 cannot be moved out of this neutral setting until after starting the engine, the safety start lever 28 is moved rearwardly to run position. The lever 28 is biased laterally by a spring 196 into locking notches 28B at the start and run positions, and must be moved transversely out of these notches before it can be moved transversely.

Abstract: 1,123,842. Valves. K. STOLL, G. STOLL, W. STOLL and G. STOLL [trading as KURT STOLL K. G. MASCHINEN U. APPARATEBAU]. 12 Sept., 1966 [7 Dec., 1965], No. 40654/66. Heading F2V. Valve for selectively supplying and exhausting a single-acting jack 148 comprises a two-part body 14, 16 with two ports 34, 36 of which one is an inlet and the other an outlet, and ports 38, 40 for connection alternatively to the jack, one of these being blanked off. A hollow valve member 62 in the position shown seats on a resilient seat 42 to isolate the ports 34, 40. A lift valve member 80 has opened the end of the sleeve to exhaust the jack through port 36. Valve member 80 is operatively connected to a diaphragm 90. On depression of a lever 132 by a cam follower roller 140 a pilot valve 126 is opened and connects the diaphragm chamber 144 with the inlet 34 to isolate the exhaust port 36 and supply the jack with compressed air. The end body part 14 can be turned through 180‹ to bring the pilot valve into connection with the port 36 so that the functions of the ports 34, 36 are reversed, Figs. 4-6 (not shown). Port 34 communicates with the valve seat 42 whereas port 36 communicates with the valve 80. The functions of the supply and exhaust valves are therefore reversed, so that in the case shown the jack is normally exhausted and in the other case it is normally supplied.

Filed: 1968-08-30
Abstract: 1,234,980. Ingot strippers. MASCHINENFABRIK AUGSBURG-NURNBERG-A.G. 30 Aug., 1968, No. 41500/68. Heading B3F. [Also in Division F2] A tongs (not shown), particularly applicable to ingot-stripping, is controlled by a set of spring units in each of which there are two spring energy stores only one of which is stressed when an actuating member moves in one direction and both of which are stressed when the actuating member moves in the opposite direction. Each energy store consists of one or more springs. In Fig. 1, which shows a single spring unit, downward movement of a member 1 compresses both the upper single spring 5 and the lower pair of springs 6, 7 but upward movement of the member 1 compresses only the pair of springs 6, 7-the upper spring 5 being merely carried upward, unstressed, by the member 2. When a set of such spring units is corporated in an ingot-stripper, downward movement of the member 1 causes tong arms to engage and merely grip the ingot and upward movement causes them to apply a force sufficient to maintain a grip which will support the load. In alternative constructions the unit may operate the opposite way, viz. downward movement of member 1 stresses only one energy store and upward movement stresses both. Also one or both of the energy stores may be elastomeric bellows, and stacks of Belleville washers may be used instead of the coil springs shown. In the other Figures (not shown), Fig. 2 is an opposite way unit (as above defined) in which one of the energy stores is a coil spring and the other a resilient washer stack; Fig. 3 is of the same general form as Fig. 1 but with the. pair of springs 6, 7 replaced by a bellows; and Fig. 4 is another " opposite way " unit in which both the energy stores are bellows.
