Patent number: 6578890Abstract: A snow removal device for elevated positions, such as roofs, while remaining on the ground. The device includes a shovel type head 10 which folds back, to assist the slide motion up the surface of a pitched roof. The shovel type head 10 is spring 14 loaded to open upon the pull action. When in use, the operator places the shovel type head 10 end of the device on top of the snow covered surface. In this position, the shovel type head 10 is hinged back so as to have the convex side of the shovel type head 10 to the surface of the snow.

Patent number: 6237258Abstract: An apparatus (10) includes a planar engagement member (20), a plurality of support members (30, 40), and a cylindrical handle member (60). The engagement member (20) can move a bulk material across a substantially planar surface. The plurality of cylindrical support members (30, 40) is fixedly attached to the engagement member (20). The cylindrical handle member (60) is fixedly attached to the plurality of support members (30, 40). The handle member (60) transfers a force through the support members (30, 40) to the engagement member (20).Type: GrantFiled: March 6, 2000Date of Patent: May 29, 2001Inventor: Stephen E. Biro

Patent number: 6219944Abstract: A manual dozer comprising a frame having a front and a rear and wheels for supporting the frame and allowing the frame to roll, The frame includes a handle extending upwardly from the frame for pushing pulling and steering the frame. A container is mounted on the frame, the container having a closed rear end and an open front end. A scoop is pivoted on the frame adjacent the front end thereof and extending in front of the open front end of the container. The scoop normally assumes a down position wherein a front edge of the scope is proximate the surface over which the manual dozer rolls. An arrangement is provided for pivoting the scoop from the down position to a raised position in which the front edge of the scoop tilts back toward the opening in the container to move scooped material into the container.Type: GrantFiled: March 26, 1999Date of Patent: April 24, 2001Inventor: Dannie R. Byers

Patent number: 6209235Abstract: A snow blocker attachment for a device used to move snow including a snow blocker having a wall member with a hole through central portion and near a bottom edge thereof, a frame to strengthen the wall, and at least one brace member formed about the hole. The snow blocker is pivotally mounted about a horizontal axis and upon a hub member which is securely attached to a bracket member which is securely attached to the snow moving device. A stop member is also securely attached to the bracket member and is used to limit the rotation of the snow blocker. In a second embodiment, the snow blocker attachment includes three plate-like members, two of which are securely attached along one side of the snow moving device and the other of which is attached across the top of the snow moving device. Instead of snow spilling over both sides of the snow moving device, the snow blocker attachment limits the snow spilling to just one side.Type: GrantFiled: May 3, 1999Date of Patent: April 3, 2001Inventor: Boyd D. Schiltz

Patent number: 6189942Abstract: Devices and methods for removing snow are disclosed. A snow removal device in accordance with the present invention includes an elongate handle having a distal end and a proximal end, and a flexible sheet having a leading edge and a leading portion proximate the leading edge. The leading portion of the flexible sheet is fixed to the elongate handle proximate the distal end thereof. The flexible sheet has a first position defining a gliding surface, and a second position wherein the flexible sheet is substantially flat. The flexible sheet is, preferably, biased to assume the first position.Type: GrantFiled: February 8, 2000Date of Patent: February 20, 2001Inventors: Francis Peterson, Paul Maire
