  • Patent number: 5058229
    Abstract: A machine for the repair and/or maintenance of floors comprises a motor connected to rotate at least one rotary tool via a drive shaft substantially orthogonal to the tool. The tool is attached to the drive shaft by a disk connected at its external periphery to the tool, and at its center to the drive shaft, which permits relative inclination of the axis of rotation of the tool with respect to the drive shaft. The drive disk is made from a material which is supple perpendicularly to its plane but which is rigid, i.e., resistant to torque, in its plane. The drive disk is mounted between the tool and the drive shaft so as to form radially at least one undulation about the axis of the tool when the machine rests on the tool and when the axis of the tool is coaxial with that of the drive shaft.

  • Patent number: 5044043
    Abstract: A drive control for a vehicle such as a floor scrubber, a floor sweeper, a pallet truck or the like, operated by a person walking or riding on a sulky behind it, includes first and second drive motors each arranged to drive a vehicle wheel. Manual means are provided whereby an operator by manipulation of a control may determine vehicle speed; forward and reverse direction; and turning right or left. A variable voltage is responsive to the operator's movements for providing an electrical signal representative of the desired speed in either the forward or reverse direction. Other movements by the operator of the control provide turning in the right or left direction. The means for detecting a turning control signal from the operator is effective to reduce the motor drive signal to the motor on the inside of the desired turn, from the level representative of the existing speed toward a no-speed level at a programmed rate.

  • Patent number: 4989293
    Abstract: A mechanism for removing water from tennis courts. A large roller having a sponge sleeve thereon is rolled over the court surface to pick up water lying on the court surface. As the roller rotates the sponge sleeve moves against a smaller roller that exerts a localized pressure force on the sponge material; water is thus squeezed out of the sponge pores into a collection tank located below the small roller. The mechanism further includes a heating device located behind the large roller to direct heated gas onto the tennis court surface to evaporate moisture that was not picked up by the roller (sponge).

  • Patent number: 4962565
    Abstract: In accordance with the present invention, an apparatus is provided wherein cleaner is applied to all or a portion of the lane and the cleaner, oil and other residue is picked up by a vacuum head trailing the cleaner applicator in one trip from the foul line to the pit leaving the lane clean and dry. The cleaner can be applied either by means of an applicator pad or by a sprayer. If desired, the cleaning operation can be limited to the last forty-five feet or so, since it is generally desirable to clean this portion of the lane more often than the front portion. On the return or reverse movement of the stripper, no cleaning operations are undertaken but cleaner may be permitted to flow from the cleaner storage tank to the applicator so that the applicator will have sufficient cleaner in it for the beginning of application on the next lane. A mechanism is provided for bowing the vacuum head so that the center is lower than the side edges so that it conforms generally to the concave shape of a bowling alley.
