  • Patent number: 5048206
    Abstract: A combined snow shoveling device and cart for removing snow from surfaces in one mode of operation and for hauling debris in another mode of operation includes a scoop arranged with a reinforced front edge for scooping snow or other material from a surface and temporarily holding the collected material, a support frame arranged with a handle portion and four wheels which are designed for movement across a surface. A first linkage member is attached to the scoop and to the support frame such that as the support frame is pushed across the surface by means of the four wheels resulting in movement of the scoop across that surface. A second linkage member is attached to the first linkage member and to the scoop and is arranged in order to change the orientation of the scoop such that any collected debris or snow can be elevated and moved to a remote site and then the orientation changed again into a dumping mode so as to empty the scoop of any collected material.

  • Patent number: 5048883
    Abstract: A snow shovel/scraper comprises a blade in form of a flat sheet of metal which has three transverse bend lines defining a base panel, a narrow scraping edge along the forward edge of the base panel, and a pair of receptacle panels which extend upwardly from the rear edge of the base panel for carrying the snow forwardly. The blade is attached to a handle arrangement in the form of a pair of rails which are adjustable in length. The upper end of each rail includes a shoulder engaging portion having a curved projection at right angles to the rail and at right angles to the scraping edge to fit into the underarm area of the user. In between the upper end and the blade is mounted a crossbar which can be adjusted along the length of the rails and to space the rails at a required spacing. The crossbar has a pair of handles turned downwardly from the rails at either side of the rails for grasping by the hands of the user with the shoulders under the upper curved portions.

  • Patent number: 5018282
    Abstract: A manually powered shovel useful for snow removal consists of a scoop supported from a frame and pivotally connected thereto adjacent its forward edge. A foot operated lever acts to rotate the scoop to eject the load. The pivotal connection preferably permits the forward edge of the scoop to rise vertically under the influence of the lever before it rotates, thereby moving the load towards the back of the scoop.

  • Patent number: 4947562
    Abstract: A self-loading tool 2 for removing snow 10 from a surface 12 includes a blade 4 attached to a handle 6. Handle 6 is attached to a neutral plane 24 of blade 4 at an angle between about 65.degree. to about 85.degree. and preferably about 75.degree.. This angle of attachment between handle and blade permits the blade to be self-loading when pushing or when pulling snow across a surface. An apparatus and a method are disclosed.

  • Patent number: 4865372
    Abstract: This is a compact shovel-like apparatus capable of performing many tasks, including digging, scooping up materials dug, and then enabling one to transport such materials to a chosen site, where the materials would be dumped without straining one's back. The apparatus consists of a removable handle, including bicycle-like handle bars, a round tubular member, and a shovel-head, capable of holding an ample quantity of materials. Runners are an integral part of the shovel-head's underneath to enable one to push the apparatus over suitable terrain, without lifting. For transportation over hard surfaces, like concrete sidewalks and streets, wheels are provided, as an option. In one embodiment the shovel-head is perforated to permit liquids to be discharged, while retaining nonliquid substances. This head's perforated surface may have a resilient plastic overlay to prevent liquids and powdery substances from passing through the holes.

  • Patent number: 4858348
    Abstract: A manually operated snow plow has a frame which is mounted on a wheel and axle assembly so that it can be pushed along the ground. A snow scoop is rotatably mounted within a pan which is positioned just above the ground surface and securely connected to the front of the frame. The scoop is spring powered so that when the scoop has collected a load of snow the scoop can eject the snow (in a flipping motion) to the side of the area being cleared. A latch retains the scoop in position within the pan and against the spring tension. Manual release of the latch by means of a simple cable connection thus activates the spring mechanism of the scoop to eject the snow. After the scoop has ejected the snow, a handle positioned at the rear of the frame allows manual retraction of the scoop into the pan thereby bringing the scoop into a position where it can receive another snow load and simultaneously loading the spring mechanism.

  • Patent number: 4629203
    Abstract: A utility cart especially suited for snow removal and other yard work and comprising a generally rectangular body having side panels, a rear panel, and a bottom panel. A pair of wheels are provided at the rear of the body for rollably engaging a support surface and a rounded nose is provided at the front of the body. The rounded nose normally slidably engages the support surface but is rollably engagable with the support surface in response to a generally upward force applied to handle at the rear of the body to facilitate upward rolling pivotal movement of the cart about its nose to dump the contents of the cart out of the open front end of the body. The cart is particularly suited for snow removal but, because of the basic open box configuration of the body, has general application for year round yard work.
