  • Patent number: 10934725
    Abstract: An angle tapping block allows for lifting a flooring plank from a subfloor surface and tapping the flooring plank. The angle tapping block includes a beating block that has multiple surfaces, including a beating block beating surface for beating with a hammer and a beating block tapping surface for tapping the side of the flooring plank. The angle tapping block also includes a lifter plate attached to the beating block and positioned below the beating block. The lifter plate can be placed beneath a flooring plank and lift from the subfloor surface for tapping.

  • Patent number: 10856685
    Abstract: A carpet stretcher device has an automatic adjusting tube that changes length with telescoping motion of an inside tube and an outside tube. A housing is mounted on the outside tube, and at least one lever is connected to the housing. A hand lever controls the motion of a spring-loaded rotating arm with a locking button positioned within the housing to insert and remove the locking button from holes in the tubes. When lifted away from the housing, the hand lever releases the rotating arms, which rotate to remove the locking button from holes in the tubes and thereby allow the tubes to telescope. The carpet stretcher may also have a floor lever that retracts when the device contacts a floor surface and extends when the device is lifted off a floor surface. When extended, the floor lever also releases the rotating arms, thereby allowing the tubes to telescope.

  • Patent number: 10710255
    Abstract: A cushion back cutter includes finger holes that are shaped to make blade changes and adjustments faster and easier. The cushion back cutter includes a center plate with a recess forming a blade pocket for holding a slotted razor blade. The center plate includes a finger opening for removing a slotted razor blade. The finger opening, which may be non-circular, crosses an upper wall of the blade pocket that supports the blade. A first side plate attached to a first side of the center plate covers the blade pocket in the center plate, and includes a blade window for removing a slotted razor blade from the blade pocket of the center plate. A second side plate is attached to a second side of the center plate, which also includes a finger opening.

  • Patent number: 10316529
    Abstract: A motorized floor stripper machine includes a motor, a frame, and a blade carrier. The blade carrier is capable of holding blades of different sizes, which can be installed on the blade carrier. The blade carrier is mounted to the frame on shock absorbers. A cam on the frame is connected to the blade carrier by a linkage that includes a bearing block, a pivot plate, a pivot pin, and a support plate. The blade carrier includes ball bearings that fit within linear channels mounted to the frame, so that when the cam is driven in an orbital motion, the blade carrier moves in a generally linear forward-backward motion. The blade carrier is relieved and includes multiple sets of holes for securing blades of different sizes.

  • Publication number: 20150282656
    Abstract: A carpet seaming iron includes a base assembly and a top cover, within which the heating and control components are located. A bimetal thermostat, an over-temperature cutoff, and/or a thermistor and thermistor cover are secured between the base assembly and top cover by an elevated surface of the base assembly. The base assembly may include a base having an outer groove such that the top cover that fits over the base and in the outer groove of the base. To keep the cord away from a user during operation, the handle of the carpet seaming iron may also be attached to the cord by a rotatable cord guard holder that extends the cord away from the handle and a semi-rigid cord guard that reduces bending of the cord.
