摘要： A bipod rifle support which may be incorporated into the stock of the rifle itself or which may be incorporated into a body member which is attachable to the forward end of the rifle stock. Support legs are normally stowed within the elongated bores with the same being removable therefrom and inserted into sockets or bores so that the support legs extend downwardly and outwardly from the stock for engagement with a supporting surface such as the ground or the like. The support legs have elastic cords secured thereto which maintain the support legs in their stowed position and in their rifle support position.

摘要： A bird feeder is disclosed wherein a plurality of spaced-apart metal mesh tubes extend upwardly from a tray to a bird seed reservoir. In one embodiment, the tubes are curved much like a barrel stave. In another embodiment, the tubes are elongated and straight cylinders. In another embodiment, the tubes are helical in shape. The tubes are spaced sufficiently apart to enable birds to pass therebetween so that the birds may gain access to the feed in the tubes from all sides of the tubes.

摘要： A cant indication apparatus includes a spirit level, at least one light receiving optical fiber, and at least one light transmitting and cant indicating optical fiber. The spirit level includes a first fluid with at least one of a first light transmittance or absorbance, and a second fluid with at least one of a second light transmittance or absorbance. A position of a bubble formed by the second fluid in the first fluid indicates at least an uncanted orientation and a canted orientation. The at least one light receiving optical fiber includes a light receiving end, and a spirit level connection end proximate to the spirit level. The at least one light transmitting and cant indicating optical fiber includes a spirit level connection end proximate to the spirit level, and an orientation indication end. Illumination through the orientation indication end indicates the bubble is in the uncanted orientation.

摘要： A cant indication apparatus includes a spirit level having a first and second surface, said spirit level containing a first fluid, said first fluid having at least one of a first light transmittance and absorbance, and a second fluid forming a bubble in said first fluid, said second fluid having at least one of a second light transmittance and absorbance, said bubble position indicating orientation. The apparatus further includes a light receiving optical fiber having a light receiving end and a spirit level connection end, said optical fiber spirit level connection end connected to said first surface of said spirit level whereupon said spirit level bubble is nearest said spirit level connection end of said light receiving optical fiber when said spirit level is in an uncanted orientation. The apparatus further includes a light transmitting and cant indicating optical fiber having a spirit level connection end and an orientation indication end, said optical fiber spirit level connection end connected to said second surface so as to be in substantial optical alignment with said optical fiber spirit level connection of said light receiving optical fiber, said orientation end illumination indicating at least one of a canted orientation and an uncanted orientation.
