Abstract: A scoring device which produces a plurality of cuts with a single pass comprises a handle and a body portion containing a movable blade holding assembly consisting of a series of razor blades mounted on a shaft with spacer elements between them. By loosening a thumb screw on the shaft the assembly can be released from a retracted noncutting position and slid out from the body portion to expose a greater amount of the blade edge which will produce a deeper cut. The assembly is then locked at the desired extended position with the thumb screw. The blades can be easily and economically replaced to maintain a sharp cutting edge and the device can be used to score fish.

The trailing end of the retriever is provided with an aperture to enable the retriever to be connected to an auxiliary drop line that allows the retriever to be lowered underwater. Slotted eyelets are situated on generally opposite ends of the retriever to serve as guides when associated with a fishing line to which a snagged lure is attached.

Abstract: There is provided an animal trap construction, in which a coil spring is adapted, upon springing of the trap, to cause a swing arm to pivot upwardly through a vertical arc, and tighten a noose around the leg of an animal. The coil spring is contained between two upstanding brackets, and an end portion of the swing arm, bent at right angles to the latter, passes centrally through the spring, and passes through the two brackets. A first bushing of cylindrical form is fixed within the end of the spring remote from the bend location between the swing arm and its end portion, the first bushing having a smaller-diameter cylindrical extension passing through an aperture in the respective bracket. A second bushing is provided at the other end of the coil spring, the second bushing having a flange which is adapted to be located between the coil spring and the respective bracket. The end portion of the swing arm passes through both bushings.

Abstract: A screwdriver assembly includes a detachable handle, a fixed non-rotatable socket and a dual ratcheting socket extending transverse to the axis of the handle to the screwdriver with the dual sockets to obtain reversal of the screwdriver rotation.

Abstract: A safety screwdriver having a handle and a shank portion which includes an axially extending tubular extension surrounding a substantially rectangular blade recessed within. In the preferred embodiment the blade and tubular extension are a unitary construction with opposite side edges of the blade integrally cast to the side walls of the tube.

Abstract: A signalling device for use when ice fishing which includes a flag that is retained in a generally horizontal retracted position when the device is set for use and moved to an upright signalling position when the fish takes the hook and pulls fishing line from a reel. The device also includes a frame supported on the ice in transverse relation to an ice hole in which the frame includes a unique structure which enables it to be easily lifted from the ice even if it is placed on the ice surface when the surface is somewhat slushy and becomes frozen to the ice thereby facilitating the fisherman pulling out a fish or removal of the device when it is desired to leave the fishing area.

Abstract: A head structure is provided defining a hollow cavity opening outwardly of one side of the head and the head includes line anchor structure thereon for attaching one end of a fishing line to the head structure. A pair of oppositely facing side-by-side self-shielding fishhooks are also provided including a pair of shanks yieldingly mounted at one pair of corresponding base ends within the cavity in laterally spaced generally parallel relation for movement of the other pair of ends of the shanks toward and away from each other. The other pair of shank ends include oppositely curved hook portions opening toward the first mentioned shank ends and the latter are telescoped within the cavity of the head structure and closely oppose opposite sides of the cavity. A resilient body is disposed within the cavity between portions of the shanks spaced slightly from the base ends thereof and yieldingly biases those shank portions away from each other.

Abstract: A cutting tool which may be pulled through sheet material to be cut has a pair of spaced circular cutting blades on a first shaft and a single circular cutting blade on a second shaft spaced vertically with respect to the first shaft and wherein both shafts are secured to a vertically standing flat body member in which a cutaway portion including a beveled surface defines paths for the work piece and a narrow section of material cut therefrom by the cutting tool.

Abstract: A hunter's knife is provided which is adapted for both eviscerating and skinning a game animal in the field. The knife has a blade portion which includes a reversely facing hook-shaped portion formed on one side, with the hook-shaped portion having a sharpened arcuate inner edge and a relatively blunt outer end. The other side of the blade has a continuous cutting edge formed along substantially its full length. The handle of the knife includes a generally T-shaped finger engaging member for securing the knife to the user's hand while the palm is either closed about the handle, or open, to thereby permit the knife to be retained on the hand while the hand is used for a non-cutting purpose, such as manipulating the animal carcass. The blade and handle are preferably integrally formed from a metallic material, such as stainless steel.

Abstract: A device for protecting a surface into which fasteners are driven. The device includes a shield portion and a handle substantially parallel to the shield. An opening is provided in the shield portion large enough to accommodate the head of a nail, and an elongated open slot extends from an edge of the shield portion. Indicia are provided spaced a predetermined distance from the edge for gauging door trim setback. A tubular member upstands from the shield and has interior dimensions great enough to receive a screwdriver blade to guide the screwdriver as it drives the screw into the surface on which the shield portion is disposed.

Abstract: A device for trapping live flying insects, such as mosquitoes including an electric light reflected by a parabolic reflector horizontally in all directions to attract the mosquitoes, and electric fan to blow the mosquitoes downwardly into a collection bag, and a valve between the fan and the collection bag which is biased to close the entrance to the collection bag when the fan is not operating and to be opened by the force of air from the fan when it is operating.

Abstract: The conveying apparatus for the bi-level irradiation chamber has a lifting device which cooperates with a bi-level rotary lock to introduce individual articles (piece goods) into the lock and to remove the articles from the lock. The lifting device allows an individual article to roll into one level of the lock while positively blocking entry of the following articles. Individual trollies are used to convey the articles within the irradiation chamber. The lifting device employs a catch to hold a trolley in position in the rotary lock to receive an article as well as a release device to release the catch after an article has been placed on a trolley.

Abstract: A spring and bail attachment for coil-spring, leg-hold animal traps which provides a firm stable base therefor to prevent tipping thereof to alarm the animal if a jaw is stepped on and which increases the traps holding power by preventing the animal from getting a solid pull or jerk when caught in the trap jaws and causing injury to its leg.

Abstract: Lift mechanism adapted to receive a pallet containing a plurality of tiers of containers thereon and move said pallet vertically approximately the height of a tier of containers to be depalletized whereby a sweep arm engages the tier of containers between parallel, spaced apart guide rails and a removable restraining arm engages the tier of containers on the opposite side to substantially encircle the tier and urge it on to a conveyor belt. As the tier of containers is urged on to the conveyor belt the restraining arm is removed just prior to the mingling of the tier of containers with containers already present on the conveyor belt.
