Abstract: The retractable swivel stud which extends to allow the attachment of a detachable gun sling swivel and strap to a firearm; and when force from the thumb or finger tip is exerted on the textured top surface of the spring-loaded stud, the stud retracts into the gunstock to a flush position and is retained there by means of symmetrically disposed slots, thus, leaving the stock free of protrusions, holes, or slots. The retracted position is retained by rotating the stud ninety-degrees in a clockwise direction, allowing the retaining device to enter detents in the sleeve's cylinder. The reversal of the foregoing procedure will extend the stud and retain it in the extended position. This movement is facilitated by the use of the spring which exerts pressure on the base of the stud at one end and the bottom of the hole in the stock at the other.

Abstract: A device for chopping or mashing fish into chum or bait size pieces while the device is immersed in water at variable depths which operates by wave action or swells acting on a cutter slidably housed inside a perforated container and at one end being attached to a boat or other floating object and at the other having a weight. The perforated container has removable end caps and a stabilizer affixed to one end cap for stabilization in water. A cutting or chopping operation is effected by wave or swell action causing the boat or floating object to rise in the water causing the cutter to rise inside the stabilized container containing large pieces of fish until the cutter impacts fish against an end cap of the container. As the wave or swell recedes, the boat or floating object drops in the water and the weight affixed to the other end of the cutter causes the cutter to fall inside the stabilized container containing large pieces of fish until the cutter impacts fish against an end cap of the container.

The ribs are hollow, opening to below the bottom wall, and have a uniform, substantially triangular shape along their length, with a radiused apex to increase the spot of contact between two engaging ribs.

Abstract: A rodent trap involving an enclosure, having at least one rodent entrance, within which a rodent-trapping member is attached to a shaft which extends through the top of the enclosure. The rodent-trapping member, which may have either a rodent-striking surface or a rodent-enclosing surface, is spring biased from a cocked position high within the enclosure to a released position. The rodent-trapping member is retained in the cocked position by means of a supported retaining pin whose inner end extends into a beveled indentation in the shaft. Release is caused by the movement of the outer end of the retaining pin into alignment with an aperature in the side of the enclosure. Movement of the outer end of the retaining pin is created by pivoting a transversely attached retaining release bar about an adjustable pivot point; such pivoting being generated through mechanical linkage by the movement of a bait holder, or in the alternative, by a hinged floor section.

Abstract: A surface grinding machine wherein the turret for two grinding tools is indexible with reference to a support by disengaging the surfaces of its two coaxial sections from opposite sides of an annular component of the support. This is effected by cylinder and piston units which move one of the sections axially of any away from the other section before moving the other section away from the annular component. The one section carries one portion of a first bearing which engages the other portion of such bearing on the support when the one section is disengaged from the annular component. The other section carries one portion of a second bearing which engages another portion of the second bearing on the support in response to disengagement of the other section from the annular component. The turret is then indexible to a different position before the cylinder and piston units effect of allow a return movement of the two sections of the turret into frictional engagement with the annular component.

Abstract: A reciprocating sander particularly adapted for sanding remote surfaces such as ceilings and walls is provided by concentrating a substantial part of the weight of the sander in a motor assembly. A lightweight extension tube extends from the motor assembly to a universal joint which in turn is coupled to a sanding attachment. The sanding attachment includes clips which secures a piece of sandpaper in an mechanism for converting angular rotation of the universal joint into relative reciprocating motion of a sanding plate and sandpaper with respect to the sanding attachment. By bringing relative force between the sanding attachment and the motor assembly, a resiliently retained driving rod within the extension tube, which is coupled to the universal joint and sanding attachment, is forced downwardly in the extension tube toward the motor assembly. This ultimately causes two clutch parts to engage thereby permitting the transmission of the motive force to the sanding attachment.

Abstract: The structural member of the present invention includes a pressure tube either having a cable tensioned between its ends or being mounted within an outer member. The pressure tube is mounted such that it can move axially with respect to the cable or the outer tube. When the tube is pressurized, some of the force is absorbed in hoop stress in the tube, and some of the force is directed to the ends of the pressure tube and to the cable or the outer member either through a piston arrangement or otherwise. When compressive loads are placed on the system, it can support force up to the preload without exhibiting Euler buckling. The system is useful for long, thin columns and for long beams where ridgidity is important. The pressure tube is not subject to compressive loading because its ends are free to move axially without compressing the tube. The pressure tube may be wrapped in high tensile strength unidirectional fiber material to withstand higher hoop strees.
