Abstract: An interconnectible structural support member for use in a support structure. The support member comprises an elongated U-shape tubular member defining opposed side arms and a bridge arm extending across a common end of each of the side arms. Each of the side arms have a free end with one of the free ends having a hinge plug protruding therefrom. The other free end is hollow and receives a hinge plug of a side arm of a further U-shape tubular member.

Abstract: The anti-theft plug or cap for the filler of a gasoline tank comprises a plate with a tapping corresponding to threading on the filler, a body rotatable in respect of the said plate, a securing element serving to render the said body integral with the said plate, and a cylindrical lock mounted in the said body and controlling the said securing element. The securing element rotatable with the rotatable body and serving to render the body fixed in relation to said plate, is provided with an elastically deformable arm resiliently removable from the axis of the plug under the action of the said lock, while its free end, when the arm has undergone no deformation, is disengaged from said teeth, although it engages them when the arm has undergone deformation.

Abstract: A counter-top stand for displaying merchandise, in which a tubular support pole is held in operationally upright position by a ground engaging base or pedestal and mounts at least one support member from which merchandise display racks or baskets are suspended outwardly about the support pole. The base or pedestal is provided with a plurality of circumferentially spaced ground engaging legs, each having an upstanding inner end portion. The several legs are fixed to a central base ring with the upstanding ends thereof projecting upwardly for insertion into the lower interior of the pole. Connection between the legs and ring is such as to pitch the latter downwardly from the general plane of the ring and thereby angularly diverging their several upstanding end portions. Downward pressure on the base ring flexes the same to converge the upstanding end portions of the legs toward one another whereby to permit their insertion into the open lower end of the tubular pole.

Abstract: A stand for a knitting machine having an upper substantially horizontal main support frame with downwardly extending legs for supporting the stand at a predetermined height above ground level and releasably attached to the main support frame, or pivotally attached thereto to enable them to be folded thereagainst. The knitting machine is clamped to a support section which is pivotally supported on the main support frame for rotation about a substantially horizontal axis for tilting the machine from one operating position to another. The support section consists of two parts extending from either end of the main support frame and interconnected by a common pivot axle with means to clamp the axle in any desired position.

Abstract: A base for an upright for forming a display stand or the like, which base is formed of a plurality of legs, said upright having a connector member insertable in the bottom of the upright and with said connector member having recesses adapted to receive the vertical bottom inner end of the legs and with the upper portion of the legs having an upper hooking end to engage openings in the upright above the bottom of the upright. The legs are capable of being readily attached to the upright without the use of extraneous fastening elements and/or tools and readily detachable for the purpose of collapsing the stand so that it occupies a minimum of space in the carton.

Abstract: A tripod cooking device is of the pyramidal tripod type and contemplates utilization of a grill which hangs from the tripod apex and which is easily assembled and dis-assembled. One of the tripod legs is larger in diameter than the others and is adapted to storingly receive all of the other components of the device. In addition, the said larger leg is formed at one end to have multi-functions, i.e. (1) it provides a guide for the grill hanging cable; (2) it provides a stop for the other tripod legs when the unit is assembled; and (3) it provides a stop to prevent fall-out of all the other components when they are stored therein. Furthermore, a wind guard is provided which selectively protects one lower side of the apparatus or alternately all three upper sides thereof.

Abstract: A stand device used in combination with a container such as a drum having a substantially cylindrical configuration wherein at least two support legs are movable into and out of supporting relation. Each of the supporting legs comprises a configuration substantially corresponding to the exterior surface of the container such that in its non-supporting position, the legs are disposed in substantially flush engagement with the exterior surface due to an indentation formed in the exterior surface corresponding to the dimension and thickness of the leg means.

Abstract: A portable projection screen including a sheet of flexible material and a collapsible support for the sheet. The support includes a central hub member having a plurality of sockets therein. Multiple extensible-contractible rods fit at one set of their ends in the hub member and radiate outwardly therefrom.

A collapsible mast is provided for supporting the screen above a horizontal surface, or for hanging it on a wall.

Abstract: A portable post support for cartridge reloading apparatus and like bench-type apparatus includes a central post preferably having threaded upper and lower ends. On the upper end of this post is mounted a collar member which is selectively locked in a desired orientation by a pressure or thrust plate and moved by a screw which is threadedly mounted in this collar member. A mounting plate for removably holding the accessory apparatus to the post support is attached to this upper collar member. The lower end of the post carries a leg support member in which four legs are removably mounted in an X-type pattern. Two front legs are the normally longer legs and a tie or retaining strap near their ends maintain these legs in the desired spaced array. A pair of shorter legs furnish the rear leg support and extends from this leg support member. An adjusting screw is associated with one of the legs and is adjusted as required to cause the four legs to rest equally on the support surface where the stand is to be used.

Abstract: An easily assembled and disassembled, aquarium stand wherein a pair of longitudinally spaced, generally vertical, springable end frame members have upper portions removably supporting an upper aquarium supporting frame and lower portions supporting a lower frame. Braces, which are fixed to the upper frame section, engage and hold the end frame members in sprung positions of assembly with the upper and lower frames.

Abstract: Disclosed herein is a pedestal base system for furniture in which base portions formed of pairs of duplex legs are easily assembled in interlocking splined fashion to form various base configurations for different articles of furniture. The vertical runs of each leg in a pair are welded to connctor tubes with the vertical axes of the connected vertical runs and tubes being in the same plane. The connector diameter and the diameter of the vertical tubular runs are dimensioned so that the legs in each leg pair are spaced from the legs in the other pair to provide clearance to facilitate assembly. The connector tubes of each leg pair are at a different vertical height and receive a vertical locking bolt or locking tube to secure the leg pairs in assembly. The leg pairs are easily assembled at the site by sliding the pairs together in the manner of a splined connection.

Abstract: A stationary jack stand for supporting such things as the draw bar end of a trailer has a base, four struts and a cap, capable of ready assembly and disassembly. On the base are four recesses into which are inserted the lower ends of the respective struts. The cap has four pockets much closer together than those of the base into which upper ends of the respective struts are slid. When a weight is applied to the top of the cap all parts remain interlocked together. To disassemble, the top is lifted free from the struts and they in turn can be lifted free of the recesses in the base.
