Abstract: A simple hand-held implement for removing ticks and other ectoparasites or small undesirable objects from the cutaneous areas and clothing of humans and animals.

Abstract: Power assisted gripping structure and method comprising a surgeon's rongeur including two elongated relatively axially moveable members having at one end thereof structure for gripping, cutting or crushing material, handle means for manually moving the elongated members axially relative to each other, electrically actuated power assist cylinder structure connected between the elongated members for assisting in producing relative movement between the elongated members on actuation thereof and switch structure for actuating the power cylinders in multiple stages. In different modifications, the structure for gripping, cutting or crushing material may be a Kerrison or Leksell rongeur tip. Alternatively, the structure for gripping, cutting or crushing may be adjustable wrench, spreader, prier suction cup or lifter structure and the power assisted gripping structure may be used in industry such as in robotics as well as in medical applications.

Abstract: A tool which can be held and manipulated in one hand, for grasping and pulling steel fish tapes of the type used to pull electrical wires through building walls comprises two identical handle members having flat and parallel front and rear surfaces. Each handle member has a convex inner transverse wall surface, and a notch cut forward from the rear wall surface behind the convex transverse wall surface to a flat longitudinal plane located approximately midway between the front and rear wall surfaces, the notch terminating in an inner transverse wall plane which serves as an anvil plane. Two handle members are pivotably joined by a pivot pin with their bottom longitudinal notch walls in sliding contact, such that a space for receiving a fish tape is provided between each convex inner transverse wall surface of a handle member and the adjacent anvil plane of the other handle member.

Abstract: A tool, particularly a nut-cracker, consisting of two twin elements each having at one end a projection shaped as a cylinder sector surrounded by an annular element forming an eyelet and by a circle sector shaped tongue, concentrical with respect to said cylinder sector shaped projection, so as to attain, by inserting said projection of one element into the eyelet formed by the annular portion of the other one element, a tool with two elements or movable hinged arms, with a rotational axis coincident with the geometrical axis of said cylinder sector projections.

Abstract: A convertible retaining ring pliers includes a pair of jaws and a pair of handles all rotatable independently about a common pivot. Each jaw includes a transverse bore spaced from and parallel to the pivot axis for receiving an elongated cylindrical latching pin. Each handle has an associated end plate disposed on one side of the jaws, the end plates having holes to selectively receive an end of a latching pin to selectively latch a jaw to a respective handle. The latching pin bores have elongated grooves and the latching pins have associated friction springs with projecting tabs coacting with those grooves to retain the pins within the assembled pliers. Elongated retaining ring tips have hexagonal shanks received in multi-sided jaw recesses to retain the tips against rotation and to enable selected rotational orientation of the tips.

Abstract: A linkage apparatus for a pair of relatively pivotal elements, such as the pivotal jaws of a hand tool, preferably includes at least a pair of linkage members pivotally interconnecting the pivotal elements. Each of the preferred linkage members is pivotally pinned to the pivotal elements and includes elongated apertures therein for receiving and supporting the pivot pins of the other linkage member.
