Abstract: A stabilizing vane for use with an archery arrow includes an elongate vane body with an inclined surface attached thereto. The inclined surface is confined substantially within the upper portion of the vane body spaced from the arrow shaft so as to be cooperable with an arrow rest. The inclined surface can be oriented to optimize arrow rotation and centering.

Abstract: An archery arrow rest includes a base to be secured to the handle or riser of an archery bow and a pair of spaced arrow support fingers extending from the base to support an arrow shaft thereon and therebetween. The fingers are configured, such as by the provision of a spring configuration on each finger, to resiliently move vertically and horizontally to an extent to follow up and down and side-to-side movement of an arrow supported by the rest during shooting of the arrow.

Abstract: A vane and nock assembly for use with an archery arrow shaft to make an archery arrow includes an elongate body with a plurality of vanes extending from and along the body. An arrow shaft is attached to the front of the assembly so that the vanes extend therebehind. A nock may be removably mounted to the rearward end of the assembly or may be integral with the assembly. The nock may be cooperable with a release device so the release device can hold the nock and drawing force can be applied to a bow string of an archery bow through the release device and nock held thereby to thereby draw a bow. The use of the nock and cooperating release device is not limited to use with the vane and nock assembly.

Abstract: A convertible table structure, providing a planar table top adapted, among other things, to support an open-arm or portable type of sewing machine, includes an apertured platform providing the table top and having a platform section fitting the aperture and adapted to mount the sewing machine so it can be lowered to a position wherein its working surface is coplanar with the work top of the platform proper. Link means, such as parallel motion mechanism, attaches the platform section to the platform proper, and means, such as a specially shaped lever rod, is provided for moving the platform section between its coplanar position and a lowered position, as well as for locking the platform section in its coplanar position. Other means are provided for holding such platform section in a selected lowered position. Legs or other suitable structure, such as a cabinet, supports the platform at a convenient working level.

Abstract: A work table of the type having a primary or base table top and a secondary table top mounted by means of parallel motion mechanism on such base table top so as to be lowered from a normal working position relative to an open-arm sewing machine resting on the base table top to an open-arm working position relative to such machine and having a short supporting leg for the secondary table top, which leg is adapted to rest upon the base table top in the normal working position, is improved by making the supporting leg retractable and arranging the parallel motion mechanism so that it does not pass dead center in the raising of the secondary table top to normal working position. In this way, considerable saving in table top material is achieved and raising and lowering thereof is facilitated.

Abstract: A folding leg mechanism for a table is adapted to be releasably locked in a firm, stable position as the leg portion thereof is swung down to extended position from retracted position against the underside of the table top. A longitudinal slot extends through at least one side of the leg and has its longitudinal axis in substantial alignment along the leg with the pivot axis about which the leg swings. A pin extends outwardly through the slot and is adapted for movement along the longitudinal axis of the slot. Spring means are provided for biasing the pin toward that end of the leg which is attached to the table. A trackway is positioned at the side of the leg from which the pin extends, so that the pin rides on and along the trackway as the leg swings between its retracted and extended positions. Abutment means are provided with which the leg makes contact when it is moved to its extended position.
