Abstract: The present invention is directed to an adjustable adapter system capable of supporting and maintaining a temporary electrical service above ground level at a building site prior to installation of permanent electrical services. The adjustable adapter system is employed in conjunction with respective vertical and bracing support members for maintaining and supporting the vertical member in a uniform, stable, substantially vertical position regardless of the contour of the underlying terrain. The subject system comprises a bracket support means which is easily connected to and adjustably movable along a vertical support member secured to the ground. The bracket support means is movable in an upward and downward substantially vertical direction to a desired position along the vertical support member for maintaining and supporting the vertical member in a uniform, stable, substantially vertical position regardless of the contour of the underlying terrain.

Abstract: Applicant's novel invention comprises an easy to use, portable, and versatile base support assembly attachable to a wide variety of equipment poles. The versatility of the support assembly is provided by a thick resilient sleeve with an internal diameter sufficient to mate with the ends of equipment poles of varying diameters. The outer surface of the resilient sleeve is mateable with an axial bore formed in the central hub of the assembly. Thereby, many different diameters of equipment poles may be accommodated by the system. Upright stability of the pole is achieved by means of an additional bolt set within the central hub, mating with a suitable threaded bore in the equipment pole. Applicant's invention has legs that fold in order to enhance portability of the base support. These legs are biased toward the folded storage position for ease of operation.

Abstract: A clarinet stand made of semi-flexible plastic, constructed in such a way that there are no loose parts to assemble. Said stand, because of a unique, riveted spring action of the legs, makes possible the folding and unfolding of said legs in a matter of seconds. With legs folded, the units size and shape is comparable to that of the contour of the clarinet bell interior thus creating a unit that may be packed and stored in said bell while the clarinet is in the case. With the legs unfolded, the unit becomes a lightweight, durable stand which will hold the instrument securely, in a vertical position, when not in the player's hands.

Abstract: An improved warning sign and sign stand assembly is disclosed and includes apparatus for attaching and retaining the sign to a stand member of the assembly. The various embodiments of the assembly also include various mechanisms for permitting the sign panel to pivot or swing under side-directed loads in order to allow a resilient portion of the stand base to deflect generally along a predetermined plane, thereby substantially preventing the sign and stand assembly from tipping over. The various embodiments are applicable in sign and sign stand assemblies equipped with provisions for selectively collapsing the entire assemblies into compact and conveniently stored configurations, as well as being applicable in assemblies not so equipped.

Abstract: A motion picture or television camera stand is disposed on a running support consisting of a central body with three arms. The arms are provided each on their free ends with a set of wheels, the wheels being steerable through a central steering system which has a steering wheel disposed around the central column of the stand and fastened thereon, an upper central cogwheel mounted on the central column, a steering shaft rotatably mounted on the central column and extending parallel to the latter, with a pinion on its upper end cooperating with the upper central cogwheel and a pinion on its lower end cooperating with the lower pinion of the steering shaft in the central body of the support and one cogbelt drive from the lower central cogwheel to each cogwheel on the shafts bearing the running wheel sets. The stand is made to be removable from the support. Two of the arms of the support are foldable against the third arm.

Abstract: An improved compact warning sign and stand are disclosed which include apparatus for attaching and retaining the sign to an upstanding frame member of the stand. The preferred attachment apparatus includes a pair of channels on each of opposite sides of the frame member into which a vertical cross-brace on the sign may be inserted. The preferred frame member also includes means for permitting the sign panel to laterally pivot or swing under side-wind loads in order to allow a resilient portion of the frame base to deflect generally along a predetermined plane, thereby substantially preventing the sign and stand assembly from tipping over.

Abstract: A musical instrument support stand, adapted for storage substantially entirely within the hollow end of the musical instrument during periods of non-use, is comprised of a base including a tripod, a post secured at one end to the base and having a free distal end for projection within the interior of the musical instrument, and a musical instrument support received on the post and adjustable over the length thereof, wherein the outer geometry of the instrument support is complementary to the inner geometry of the musical instrument whereby the latter may be received by the former and supported thereon.

Abstract: A survey tripod for use in uneven terrain which includes a center pole and a pair of support legs, each leg is pivotally attached to a slideable clamp on the upper part of the pole for vertical adjustment of each leg. The lower end of each leg is connected to the pole with a brace, both ends of each brace having pivotal connections for adjustment of the legs. There is a clamp connecting both braces to the lower part of the pole which permits anchoring the brace, and permits additional vertical adjustment of the legs relative to the center pole. A telescopic tube within the pole can be extended upwardly to increase the effective height of the pole. A survey instrument can be attached to the tip of the telescopic tube.

Abstract: Multiple pivotable legs are radially extendable from a pole stand for a table top to permit support of the table top by pivotal extension of the legs for supporting the stand or the legs may be radially collapsed to permit engagement of the lower end of the stand with a fixed recess.
