  • Patent number: 4608774
    Abstract: This invention relates to gravity operated roach traps in general, and more specifically to a two piece molded roach trap having an improved rectangular funnel design, which produces a steeply angled funnel surface, having an enlarged opening to insure that the roach will be deposited directly into the trap receptacle and will not be able to use the opposing wall surfaces to impede or frustrate its descent into the receptacle. In addition, the funnel is also provided with a recess on at least one of its faces, for retaining a lure or attractant to induce a roach to enter the funnel.

  • Patent number: 4574517
    Abstract: A light weight leader used for fishing is switched automatically to a heavy line when a large fish is hooked. Thus a connector link of the length of the leader has a heavy fishing line attached to one end and a detent mechanism for receiving the hook at the other to thereby replace the leader. A friction pad holding the heavy line in a loop for extending the leader from the other end of the connector permits the line to be cast and used for small fish with the light leader but gives way to the tension when a big fish is hooked and lets the hook be detented into the connector element for landing with the heavy fishing line.

  • Patent number: 4571878
    Abstract: Fishing tackle including a casting float comprising two members. The first member constitutes a bobber portion. The second constitute a line storage drum. The two members are telescopically moveable relative to each other. During casting the relative movement actuates the release of fishing line from the line storage drum, prior to the float hitting the water.

  • Patent number: 4557068
    Abstract: A padded leghold trap of the pivoting jaw type includes recessed portions of the jaws in which respective pads are disposed. The pads each have concave facing surfaces with an inner edge that barely touches the inner edge of the other pad in the sprung position of the jaws, leaving the remainder of the concave facing surfaces mutually spaced. A trapped animal is held between the padded jaws which spring closed and traps the animal's leg without breaking the leg or causing edema. Attempts by the trapped animal to pull its trapped limb from between the jaws causes the radially inner pad edges to roll over toward the limb and thereby increase the retention forces. A retainer for the pad is disposed over an access slot in the pad, which access slot is provided to deploy the pad on the jaw. The retainer includes a bent lip which deforms the pad toward the jaw to prevent the pad from being pulled off the jaw by a trapped animal.

  • Patent number: 4555863
    Abstract: A snare trap which comprises an outer frame, a spring-actuated inner frame secured to the outer frame and adapted to pivot about an axis normal to its longitudinal extent from a first position where the inner frame lies within the outer frame to a second position after a rotation of A latch holds the inner frame in its first position, a trigger plate releases the latch when depressed by an animal paw. A snare is removably secured to the outer frame and defines a noose around the trigger plate, which noose is adapted to be drawn by the inner frame around the leg of an entrapped animal when the trap is sprung.

  • Patent number: 4553305
    Abstract: A tool adapted for use by a pipefitter in welding a length of pipe to a fitting in which one end of the pipe is accommodated with a predetermined spacing between the end of the pipe and an internal shoulder within the fitting. The tool has jaws which may be clamped on the pipe when the end of the latter is in abutting engagement with the shoulder of the fitting and includes spacers that are movable to a position between the jaws and the end of the fitting to provide a predetermined spacing between the free end of the pipe and the shoulder of the fitting. The tool also includes scribers for marking the pipe and the fitting in such manner as to facilitate verifying that such gap has been provided between the end of the pipe and the shoulder of the fitting.

  • Patent number: 4536985
    Abstract: This invention relates to a self-propelled, preprogrammable fishing lure which utilizes a first timer whose interval of operation may be varied by the user to control a second timer which in turn operates a propulsion means over a predetermined period of time, and which allows for an interval period of deactivation of the pump and motor by causing the variable interval of operation of the first timer to be greater than the operation period of the propulsion means.

  • Patent number: 4534403
    Abstract: A hot chamber die casting machine employing a substantially horizontally arranged charging cylinder and piston. The piston employs a charging head, a sealing head and a rigid member therebetween. The device is arranged to allow access to the piston for changing rings and the like without substantial loss of material from the pot. A safety cover is provided with doors which do not remain open without external support. A cooling system is shown to reduce the temperature of the seal at the open end of the cylinder so that the material within the pot will partially or completely solidify to form an improved seal.

  • Patent number: 4529836
    Abstract: An apparatus for interfacing materials and absorbing disparate thermal expansions thereof utilizes a woven wire mesh to support a predetermined thickness of a first soft solder which absorbs expansions, and utilizes a second soft solder having a lower melting point than the first to coat the surfaces of the wire mesh/first soft solder combination so that the materials can be bonded thereto.

  • Patent number: 4516352
    Abstract: An artificial crawfish lure. The lure (10) comprises a resilient body (12) and a hook assembly (14). The resilient body (12) is shaped and dimensioned to resemble a crawfish and comprises a head portion (28), a midbody portion (30) and a cantilevered tail portion (32). The cantilevered tail portion (32) is an arcuate member extending in a spiral manner, downwardly, inwardly then rearwardly of the midbody portion. The tail portion terminates in a fin member (44) which is disposed substantially perpendicular to the midbody portion. A fabrication seam (46) is disposed on the ventral side of the head (28), midbody (30) and tail portions (32) and a fabrication seam (52) is disposed on the dorsal side of the head (28), midbody (30) and tail (32) portions. The fabrication seams (46) and (52) allow lateral movement of the tail portion (32).

  • Patent number: 4506471
    Abstract: A line attachment device for a fishing float having a buoyant body member, the device consisting of a stem fixed in the body member and projecting outwardly therefrom, and having at its outer end a conically enlarged head terminating in a flat, circular flange having a re-entrant peripheral lip of larger diameter than the head, the lip, flange and head having a first notch extending radially inwardly from the outer periphery thereof, and a second generally U shaped groove formed therein in a plane generally parallel to the stem and opening at its ends through the outer end of the head. A plunger slidably encircles the stem and has its outer end socketed to mate with said stem head, flange and lip, but does not enter said notch or groove. A spring biases the plunger outwardly on the stem, but the plunger may be retracted manually to permit a fishing line to be looped around the stem head.
