  • Patent number: 6237459
    Abstract: A cove base cutting guide tool for guiding a knife through the guide tool and making a mitered cut on a cove base material. The guide tool includes a base and a plurality of tower members extending vertically from the base forming a first and second guide wall. The first and second guide walls define a groove having the same general shape as the cove base material to be cut. The groove includes a generally straight portion extending from a top to a bottom of the first and second guide walls with an open end at the top of the guide walls. The groove is wider at the bottom of the straight portion than the top of the straight portion. The first and second guide walls flex away from one another at the top of the groove when receiving the cove base material, and apply friction to the cove base material at the top of the cove base material when the cove base material is inserted into the groove.

  • Patent number: 5932049
    Abstract: A bearing assembly for supporting a drive shaft includes a cylindrical housing, and a plurality of elastomeric bearing sections disposed within the housing. The bearing sections are bonded to the housing by first applying a pattern of alternating parallel lines of adhesive to the inner diameter of the housing, installing the bearing sections, and inflating an airbag within the housing to thereby apply a uniform radial pressure to the inside of the housing while the adhesive cures.

  • Patent number: 5888017
    Abstract: A resilient expansion joint insert member for insertion into the expansion joint between adjacent concrete floor slabs. As the concrete slabs move further apart due to settling or thermal contraction, insert member covers the widened gap. Likewise, as the concrete slabs move closer together due to settling or thermal expansion, the insert member is compressed and absorbs the force as the slabs move against each other. The flooring material on the slabs near the expansion joint move beneath a cap of the insert member.

  • Patent number: 5772514
    Abstract: A device reducing the deleterious torque in a shock absorbing, rotary drive coupling unit used with a rotary mine drilling machine comprising: a drive plate connectable to a drive shaft of the rotary drilling machine, a driven plate connectable to a driven shaft which has a drill bit, a center portion for coupling the drive plate to the driven plate wherein the center portion includes a deformable shock, vibration and torque-absorbing member, and torque-relief means comprised of a first engagement member(s) connectable to the drive plate and a second engagement member(s) connectable to the driven plate. When the drill bit snags or jams during the operation of the rotary drilling machine, the torque-absorbing member deforms and absorbs some of the torque generated therefrom.
