  • Patent number: 3944196
    Abstract: A recoil assembly for track type vehicle includes a housing having a preloaded spring assembly mounted therein. The housing is an open sided housing having a pair of ends with aligned apertures formed therein. The spring assembly includes a pair of spaced apart seat members confining a pair of compression springs therebetween with adjustable means in between the seat members for compressing the spring. One of the seat members includes a projection extending into the aperture at one end of the housing and the other seat includes means receiving the extension of a bushing extending through the other aperture. This bushing and aperture arrangement retains the spring assembly within the housing. The open side of the housing is provided with a fixed bar and a removable bar for removably confining the spring within the housing in a functional position.

  • Patent number: 3936919
    Abstract: A plural range pressure regulator construction having a housing provided with an inlet and an outlet separated by a valve seat that is controlled by a valve member that is interconnected to a flexible wall carried by the housing. Biasing means are carried by the housing for acting on one side of the wall to tend to move the wall in one direction relative to the housing, the biasing means comprising a plurality of separate spring means each acting on the wall to provide one pressure range for the pressure regulator construction. The housing has a storage space for storing one of the spring means so that the same will not act on the wall whereby the remaining spring means acting on the wall will provide another pressure range for the pressure regulator construction.

  • Patent number: 3933345
    Abstract: Two consecutive portions of a single helical spring having a zig-zag arrangement are mutually interfitted with each other with their turns remaining out of contact, and with their taxes being in substantially tangential contact or, at the most, intersecting at an acute angle not in excess of 10 degrees. The ends of the two portions are firmly connected to each other directly at their deflection points, and the interconnection preferably is connected to one end of a soft spring whose opposite end is fixed to a rigid support. Consecutive helical spring portions may be wound in the same direction or in respective opposite directions.
