Patent number: 4271549Abstract: A relatively small watercraft includes a pair of spaced and usually parallel pontoons. A personnel station extends generally between and above the two spaced pontoons. A structural frame of tubular members or bars supports the personnel station; the tubular members may be selectively connected to the pontoons, or the frame may be permanently connected to them. In one embodiment wherein the structural frame and the pontoons are only temporarily connected, a plurality of eye bolts and specially positioned slots are utilized so that the eye bolts need never be removed from the watercraft. (In this embodiment, there are no connecting pieces to ever get lost, even when the three main sub-assemblies of the watercraft are disassembled.) The eye bolts are aligned longitudinally with the slots for disassembly, and turned transversely to the slots to hold the tubular members to the pontoons. Dimples or recesses in the tubular members can be provided to inhibit unwanted rotation of an eye bolt.Type: GrantFiled: January 12, 1979Date of Patent: June 9, 1981Assignee: Advanced Marine Concepts, Inc.Inventor: Roy L.

Patent number: 4271552Abstract: A torpedo recovery system including an expandable sleeve surrounding a portion of the torpedo. Upon activation of the recovery system gas is introduced into the sleeve, causing it to expand. The sleeve is clamped firmly at two distinct longitudinal positions along the torpedo and is releasably clamped at a third longitudinal position.

The chain pipe-cutters include: a tensioner which is a deformable system formed by a cylindrical rod fast with a support, a slider slidably mounted on said rod, said support bearing four articulated rockers connected to the slider in pairs by two links and having their lower ends shaped as hooks to permit attachment of the chain thereon; said cylindrical rod cooperating with a handle through the agency of a screw-thread and said handle being formed by two superimposed cylindrical elements and having four superimposed lobes arranged cruciform-fashion.Type: GrantFiled: June 7, 1979Date of Patent: June 9, 1981Assignee: ViraxInventor: Jean L. C. Aubriot

Patent number: 4271592Abstract: A hand tool with a knife, saw, screwdriver blade or the like in which a handle is formed of two U-shaped members of equal length that are pivotally articulated on a blade-retaining piece at free ends of their respective arms about pivot shafts that are perpendicular to each other. The U-shaped members are swingable in succession over a blade as a protective housing that encloses it. The blade is removably fixed by a screw in a receiving slot of the blade retaining piece. The two shafts are mutually offset or staggered in a longitudinal direction of the blade approximately by a thickness of a base portion of the U-shaped member.Type: GrantFiled: February 5, 1980Date of Patent: June 9, 1981Inventor: Hans-Gerd Hoptner

Patent number: 4271593Abstract: A wire cutter having a pair of partially overlapping blade-shaped jaws pivotally connected, each jaw having an operating handle, a pin in one jaw blade being received in a slot in the other jaw blade to limit the pivotal movement, a plurality of holes in said jaw blades, said holes being countersunk in the outer surface of one of said blades, said holes being in alignment when said handles are in the maximum open position for the insertion of a wire to be cut, said holes in non-alignment when said handles are squeezed, thereby permitting said blades to cut wire, and a spring between said handles to return said handles to the open position.Type: GrantFiled: June 12, 1979Date of Patent: June 9, 1981Inventor: Samuel C. Smith

Patent number: 4271594Abstract: An improved filament trimmer of the type in which a rotary drive means having a hollow filament feed shaft is frame mounted and has an improved slinger head attached to said hollow shaft with an arcuate bore therethrough in open communication with the hollow shaft for swinging the cutting filament line in a radial plane to the shaft axis. A positive filament feed control is used for metering the cutting line to or from the slinger head.Type: GrantFiled: November 7, 1978Date of Patent: June 9, 1981Inventor: Lauren G. Kilmer

Patent number: 4271595Abstract: A housing and cutting line assembly for a vegetation cutting apparatus of the type which cuts with rapidly moving lines extending from a rotating housing includes metallic line guides taking a configuration which addresses the effective guiding of the extending of the lines exteriorly of the housing and the dissipation of heat from the lines. The line guides each have a trailing side wall bearing surface for the associated line, which includes two linear surface portions angularly disposed with respect to one another, and a leading side wall bearing surface which includes a linear surface portion and a curvilinear surface portion. The linear leading side wall surface portion is substantially uniformly spaced from an inner, linear trailing side wall bearing surface portion, and the curvilinear surface portion of the leading side wall bearing surface curves away from this inner surface portion.Type: GrantFiled: July 26, 1979Date of Patent: June 9, 1981Assignee: Hawaiian Motor CompanyInventor: Jon A. Rahe

Patent number: 4271596Abstract: An instrument and method is provided for accurately determining the geographic coordinates of a specific location on a map. The instrument comprises a flat transparent plastic sheet having a variable length scale printed thereon which is defined by a plurality of straight lines radiating from a common point. Indicia are also printed on the sheet for designating the radiating lines as graduations of a scale comprising either 2.5 or 5 minutes, and with each minute being further broken down into sixty seconds. To determine a coordinate, the location in question on the map is projected to the border along a direction parallel to one set of the geographic coordinates. The transparent sheet is then placed over the map, and the scale is aligned with respect to the border such that the outermost of the radiating lines directly overlie the tick marks on the map between which the projected location falls. The scale is then read above the point at which the projected location intersects the border of the map.Type: GrantFiled: November 6, 1979Date of Patent: June 9, 1981Inventor: G. Robert Ganis

Patent number: 4271597Abstract: Method and apparatus for making a plurality of different keys, each constructed to open each rotary cylinder lock in the same series, or sub-series, called "masterkeying". The disclosed masterkeying tool comprises a calibrated plate, having one or more pin grooves, and a key-supporting platform which moves transversely to permit a selected bitting of a test key to register with a selected pin groove on the calibrated plate. Tumbler pins interposed in the pin groove are seated in a selected bitting of the test key and are aligned in the groove to reach the indicated shear line.The process is repeated for corresponding bittings in each of a series of keys, beginning with the key having the highest bitting and ending with the key having the lowest bitting.Type: GrantFiled: July 31, 1979Date of Patent: June 9, 1981Inventor: Louis F.
