Definitions

  • a follower having on one side a central spherical bearing face, a central friction member hav-' ing at one end a bearing surface corresponding to the bearing face on said follower, wedge actuated friction shoes bearing against said friction member, and a spring adapted to hold the said bearing surface of the friction member against said bearing face on said follower and the said friction member normally at right angles to said follower.
  • a follower having a spherical depression on one face thereof, a central friction member having a boss on one end thereof adapted to bear in and turn in said spherical depression, friction shoes adapted to bear on said friction member, Wedges for forcing said shoes against said friction member, and a spring adapted to hear at one end against said central member and to hold it against said follower.
  • shock absorbing mechanism a fo1- lower, a central friction member having an equalizing bearing on said follower, Wedge actuated friction shoes bearing against said friction member, an enlargement extending at an angle to the body portion of said friction member and a spring adapted to bear at one end upon said enlargement and'to hold it against said follower.

about the friction member, wedges for forcing the shoes against the friction member, and a spring adapted to bear at one end upon said central member and to hold'it against the said follower.
2. In shock absorbing mechanism, a follower having on one side a central spherical bearing face, a central friction member hav-' ing at one end a bearing surface corresponding to the bearing face on said follower, wedge actuated friction shoes bearing against said friction member, and a spring adapted to hold the said bearing surface of the friction member against said bearing face on said follower and the said friction member normally at right angles to said follower.
"3. In shock absorbing mechanism, a follower having a spherical depression on one face thereof, a central friction member having a boss on one end thereof adapted to bear in and turn in said spherical depression, friction shoes adapted to bear on said friction member, Wedges for forcing said shoes against said friction member, and a spring adapted to hear at one end against said central member and to hold it against said follower.
4. In shock absorbing mechanism, a fo1- lower, a central friction member having an equalizing bearing on said follower, Wedge actuated friction shoes bearing against said friction member, an enlargement extending at an angle to the body portion of said friction member and a spring adapted to bear at one end upon said enlargement and'to hold it against said follower.
