Abstract: A ride-on floor machine, including: a frame including a lower frame portion; a drive system carried by the frame; and a blade control system carried by the lower frame portion, the blade control system including: a blade holder pivotably attached proximate a front end of the lower frame portion; and a linear actuator coupled to the blade holder at a first end and coupled to the lower frame portion at a second end, wherein the actuator extends along a center line parallel to the lower frame portion and is operative to move between an extended position where the blade holder is in an up position and a retracted position where the blade holder is in a down position.

Abstract: An overload control device for use with a floor machine having an electric motor is disclosed. The overload control device can include a power input and a power output connectable to the electric motor. The device can include a load detector, a current sensor operative to sense a current value supplied to the motor via the power output, and a cutoff relay interconnecting the power input and the power output. The cutoff relay being operative to supply power from the power input to the power output when activated, and interrupt power when deactivated. A controller receives a load present indication from the load detector and activates the cutoff relay if a load is present. The controller receives a current value from the current sensor, determines if the current value is greater than a threshold value, and deactivates the cutoff relay when the current value is greater than the threshold value.

Abstract: An electrically activated hot-melt adhesive tape for adhesively joining objects such as adjacent sections of carpet. The tape has a base which is typically paper, and an electrically conductive ink-like material is sprayed or printed on the base to form a thin central heating section, and thicker and hence lower-resistance conductive strips extending along opposite edges of the heating section. Scrim supporting beads of hot-melt adhesive is secured over the heating section. Alternatively, the heating section and conductive strips, which may be segmented, are applied to an underside of the base, and the scrim and adhesive beads to the opposite side of the base. An activating tool has extending electrodes which electrically contact the spaced-apart conductive strips to pass a current through the heating section to melt the adhesive beads in preparation for application to the objects to be joined.

Abstract: A heat shield for the upper surface of a carpet seaming tape iron, preferably formed of polytetrafluorethylene or other heat resistant synthetic material, covers only so much of the upper surface of the iron as is needed to assure that the carpet backing coming into contact with the iron will not be overheated. Since some heating of the carpet backing is desirable in the hot melt carpet seaming tape operation, the forward and rear surfaces of the iron are left at least partially exposed so that the carpet backing will have some direct contact with the hot metal heat transferring surface at the top of the iron's body. The heat shield is contoured so as to fit closely down against the surfaces of the carpet seaming tape iron, avoiding any unnecessary deflection of the carpet edges during the seaming operation and providing an integral feel to the assembly. Assembly may be as original equipment or as a retrofittable addition to an iron.
