Title: Endless track idler recoil spring assembly and method of installation and removal
IPC: B62D55/30
Filed: 1975-12-19
Abstract: 1515907 Endless track idler recoil mechanisms FIAT - ALLIS CONSTRUCTION MACHINERY Inc 19 Dec 1975 [2 Jan 1975] 52092/75 Heading B7H An idler wheel recoil spring assembly for an endless track vehicle comprises a spring 76, an adjustable spring retaining member 44, an hydraulic ram 51 abutting the spring, a yoke 28 connected to the idler 18 and a pushrod 30 abutting the ram piston 60. The spring is positioned within an open topped casing 36 and surrounds a guide tube 78, the spring being trapped between a push-plate 80 on the tube and the end 38 of the casing. A member 44 having a cylindrical part 46 and flange 48 is connected by bolts (50) (Fig. 5, not shown) to a wall plate 40 of the casing, the bolts passing through untapped holes (47) in the flange 48. The cylindrical part 46 abuts the push plate 80 and slidably houses the ram cylinder 52 which also abuts plate 80. The push rod 30 is mounted in holes 33 on equalizer bar support 32 and is received in a recess 62 in the piston 60. In assembly the casing 36 is mounted on the track frame 11 and the spring and guide tube inserted therein. The ram cylinder is assembled with the member 44 which is attached by bolts 50 to the wall plate 40. Initially the cylinder and cylindrical part 46 contact push plate 80 and the outer end of the piston 60 contacts the equalizing bar support 32. Hydraulic fluid is forced into the cylinder to expand the ram and compress the spring. Bolts 50 are then tightened until the cylindrical part 46 contacts the push plate 80. This process is repeated until the bolts 50 are fully tightened. The fluid is then exhausted from the ram, the push rod 30 fitted, and the ram re-expanded to create an incompressible link between the yoke and spring.

A control for a vehicle automatic transmission, e.g. hydraulically controlled, comprises a manual lever 16 which positions both the PRND range control valve and the park lock pawl through two separate cables (20), (28), Fig. 5 (not shown), connected to plates 12, 22 respectively, the plate 12 having a clevis connection with the lever 16, and carrying a pin 18 which, on moving the lever from reverse to park, engages the plate 22 at 25 to pivot the plate, the pin entering a recess (24), in the plate, and engaging the park lock. On returning to reverse, the pin pulls the plate 22 back to disengage the park lock. In the neutral and drive positions of the lever 16, the pin 18 engages a curved cam surface (23) adjacent the recess (24) to hold the lock disengaged. A compression spring unit (27) in the park lock cable (28) facilitates disengagement of the park lock when the vehicle is parked on an incline.

Abstract: 1374599 Locks MRT MAGNET-REGELTECHNIK GmbH 30 Nov 1971 [11 May 1971] 55482/71 Heading E2A A magnetic lock comprises a housing 101, at least a pair of blocking members comprising notched discs 102, 103 pivotable to locking or releasing position with respect to a control member a bolt 108, the discs having each a magnet 104, 105, a key having at least a pair of parallel magnets with like poles adjacent for each disc the key being positioned adjacent the discs to turn the discs to releasing position as shown in Fig. 1. The bolt is withdrawn under spring pressure. As shown in Fig. 5 a bolt 203 is spring urged to project through notches in rotatable magnetic discs 219.By applying a magnetic key to a plate 215 connected to the bolt a pivoted, magnetic latch 229 mounted on the housing beneath the plate is pivoted from obstructing position into a recess to allow the plate to be moved and the bolt to be projected against the action of the spring. Removal of the key causes the discs to pivot and prevent withdrawal of the bolt. A bolt 313, Fig. 7 is prevented from projecting by pivoting magnetic discs 307 which are rotatable by a magnetic key to align bores 331 therein with pins 329 to allow movement axially of the bolt when pressure is applied by the key 333. A projecting, blocking member 337 on a cylinder 303 within a case 301 engaging a groove in a disc aligns with an axial slot therein when the key is applied. In a further embodiment, there are three discs 407, Fig. 8 with axes parallel to a unit with three teeth 427. The unit normally prevents projection of the bolt but when a magnetic key is applied the discs are rotated to align notches therein with the three teeth so that pressure applied to a plate 415 connected to the bolt 411 causes the bolt to move to projecting position. A plurality of locks may have different magnetic 433 applied to the units to rotate them to the inoperative position, all the locks may be released by a master key. To prevent bolt operation by an incorrect key of greater magnetic strength than the correct key a soft iron part is spring urged away from the discs application of the incorrect key raises the soft iron part to clamp the discs against rotation to the releasing position.
