  • Patent number: 11034000
    Abstract: A frame block clamp includes first and second block portions dimensioned and configured to provide first and second tube receiving apertures for snugly receiving a predetermined tube; and to provide first and second ā€œVā€ configured recesses in respective first and second side portions when portions of said first and second block portions are cooperatively engaged. The frame block clamp further includes a retaining spring dimensioned and disposed to urge together predetermined portions of the first and second block portions to ultimately secure a tube in the first or second receiving apertures. The frame block clamp is ultimately secured in a vise to allow a person to service the tube secured in the first or second receiving aperture.
    Type: Grant

  • Patent number: 10982164
    Abstract: A device for starting and maintaining a campfire includes an inner combustible structure formed from a plurality of inner combustible members having bottom end portions separated and secured to a top planar wall of a combustible lower support member. The device further includes an outer combustible structure formed from a plurality of outer combustible members having bottom end portions separated and secured to edge portions of the combustible lower support member. A fire accelerant is disposed in an inner portion of the inner combustible structure to promote a faster starting campfire.

  • Patent number: 7063000
    Abstract: A portable guide for use with portable power tools such as saws and routers to assist in making straight cuts or grooves precisely located in panels or sheets by moving the tool along a planar side surface 64 of a guide bar 10. Clamp assemblies 20R and 20L secure the guide bar 10 to the workpiece and support the workpiece by clamping the workpiece on both sides of the line of cut via a tightening clamp screw 26 and planar clamp plate 28 that forcefully urge the workpiece into contact with an angle portion 66 of the frame 21 of the clamp assemblies 20R and 20L. The clamp assemblies 20R and 20L are designed to avoid interference between the clamp assemblies and the cutter portion of the power tool. A template 40 precisely locates the clamp assemblies relative to the line of cut.

A template 40 precisely locates the clamp assemblies relative to the line of cut. A lateral guide 30 may be attached to the tool without tool modification. The lateral guide 30 interacts slidably with the guide bar 10 and maintains engagement between the side surface 64 of the guide bar 10 and the power tool.

  • Patent number: 6079309
    Abstract: A portable guide for use with portable power tools such as saws and routers to assist in making straight cuts or grooves precisely located in panels or sheets by moving the tool along a straight edged guide bar (10). Clamp assemblies (20R) (20L) secure said guide bar to the workpiece and support the workpiece by clamping on both sides of the line of cut. Means are provided to avoid interference between said clamp assemblies and the cutter. A template (40) precisely locates the clamp assemblies relative to the line of cut. A lateral guide (30) may be attached to the tool without tool modification. Said lateral guide interacts slidably with the guide bar (10) and prevents movement of the tool away from the intended line of cut.
