  • Publication number: 20150135637
    Abstract: It's now accepted that hurricane tie-down straps should be wrapped over the top of rafters/trusses, avoiding the crucial weakening effect of wood splitting around the nails of common side-nailed straps. That “wrap-over” is easy to do during construction but has been difficult and costly to do for existing houses, where the sheathing and roofing is in the way. But now such wrap-over can be an easy retrofit, according to this invention: Without damaging sheathing or roofing, force the sheathing off the rafter/truss just enough to allow a special strap to be pushed through the gap, then proceed much as in new construction. Unique wedge-blade and lever types of devices quickly create just the right gaps.

The tool is configured in such a way as to make removal of a shingled roof much easier and with much less strain and effort on the part of the roof remover. The device provides for easy insertion of elongated arms under the shingles in the gap between the boards in the roof base and for a vertical engagement of shingle layers, which makes both inserting the device under the material to be removed and lifting of the layers much easier. After insertion of the device, the shingles are lifted until they are detached from the roof base or the handle of the device may be rotated to lift and disengage the roofing material from the roof base.

  • Publication number: 20020053261
    Abstract: A lifting tool has a handle, a lifting tool head, and a means for slidably mounting the lifting tool head on the handle such that the lifting tool head slides with respect to the handle between an extended position and a compressed position. The lifting tool further includes a means for biasing the lifting tool head towards the extended position. Since the lifting tool head can slide against the bias of the means for biasing, the lifting tool can absorb some of the shock if the lifting tool head strikes a hard obstruction, thereby sparing a user from the strain and potentially avoiding an injury that could result from the strain.

  • Patent number: 6371542
    Abstract: A load lifting accessory may be provided which is adapted to be affixed to the shaft of a shovel. The load lifting accessory comprises a bracket, a support arm, an extension member and a retractor arm. The bracket, which has a support arm pivotally attached thereto, is adapted to embrace the underside of the shaft of the shovel when the shovel is oriented in a normal shovelling position. The first end of the retractor arm is pivotally and slidably attached to the first end of the extension member, whereas the second end of the retractor arm is pivotally attached to one of the first and second side edges of the support arm. In an alternative embodiment, an actuator is used instead of an extension member. The purpose of the load lifting accessory is to relieve the user of severe vertebral and back muscle strains which are associated with shovelling.

  • Patent number: 6339975
    Abstract: A roofing tool having a blade of generally quadratic shape with a front edge, a rear edge, and side edges joining the front and rear edges. The tool has two teeth extending forwardly from the front edge of the blade, at least the front ends of the teeth adapted to be easily slipped under roofing shingles. The inner sides of the teeth are beveled allowing the teeth to slip under the heads of shingle nails to be able to lift them. A nail receiving slot is provided in the blade between the teeth extending rearwardly from the front edge of the blade. This slot can be used to lift shingle or framing nails. At least the front ends of the teeth can be spaced apart a distance greater than the width of roof framing members so the teeth can straddle the framing member and the teeth can be used to lever sheathing boards up from the framing member.

  • Patent number: 6318213
    Abstract: A tool primarily for use in stripping asphalt and wood shingles from a roof consisting of a blade, a body, and a handle. The blade has a wide forward portion with front serrate edge, transverse bends for rigidity, and primary fulcrum. The novel and unique front edge is curved to accommodate sags in the underlying roof and to facilitate insertion under shingles. The body is attached firmly to the blade and contains an upper portion to receive an elongated handle and an undercarriage curved in the vertical longitudinal plane providing a variable mechanical force ratio as the operator uses the tool to remove the roof shingles by vertical travel of the handle. For shingle removal, the front edge of the blade is slid or pushed under shingles and the handle lowered toward the roof surface.

  • Patent number: 6237975
    Abstract: According to the present invention there is provided a shovel comprising an elongate body, a handle at an end of the body, a digging end at a respective end of the body which is arranged to move material and a bent portion on the body adjacent the digging end. The bent portion is formed such that an engaging end is arranged to engage a ground surface creating a fulcrum affect when the handle is forced downwards by a user thereby tilting the digging end off the ground surface. The bent portion is generally U-shaped having a first bend at the digging end which extends downwards therefrom, a second bend which extends upwards and a third bend which extends rearwards generally longitudinally with the digging end. The second bend has a larger radius than the first and third bends defining a rounded rolling surface such that a contact point of the fulcrum is varied longitudinally as the shovel is tilted. The shovel body is formed from a single elongate tube.
