Abstract: A locking device for infinitely varying the inclination of a drawing board mounted about a hinge axis along one edge of a base or table structure between a maximum tilt angle and a minimum angle such as horizontal in which a rod is pivotally connected at one end to a drawing board and extends downwardly alongside the base structure, a lock member is pivotally mounted on the base structure and has a plate portion having a hole therein to receive said rod, said hole having a configuration providing frictional contact with said rod surface in relative angular positions of the rod as determined by the inclination of the drawing board and by the pivotal movement of the lock member, the configuration of the hole maximizing such frictional contact, and a magnet on the base structure cooperable with said lock member to hold the lock member in release position with respect to the rod, the lock member being automatically disengaged from said magnet in one position of the drawing board.

Abstract: A support for mounting an object on a vertically disposed hollow wall having an exterior surface and an interior surface spaced from each other by a predetermined distance. The support comprising a body, an intermediate leg and a wall piercing member. The body is an elongated planar member having a first and second end. The leg is a planar member approximately equal in length to said predetermined distance and is connected to the first end of said body perpendicularly to the plane of the body. The piercing member is connected to said leg portion parallel to the plane of said body means and is arranged to pierce through the wall portion connecting said surfaces, whereupon, when said support is rotated downward with respect to said wall portion, the piercing member abuts said interior surface of the wall with the body abutting the exterior surface and the leg resting on the wall material contiguous with the opening produced by the piercing action.

Abstract: The present invention is directed to means for demountably securing the housing (3) of a container for presenting decorative items to a smooth surface irrespective of its inclination. A rubber suction cup (12) is operatively attached to the bottom of the container housing (3), and a pin (11) is secure to, and extends upwardly from, the central, distortable, portion of the cup (12). The pin (11) is axially translatable within a sleeve guide (4) mounted behind the cup (12) on the housing (3). At least one thrust rod (6) is translatable radially with respect to the pin (11) and slideably received within a pair of aligned slots (5 & 13) which penetrate the pin (11) and sleeve guide (4), respectively. The thrust rod (6) presents an obliquely inclined camming surface (9) which engages the slot (13) such that radial translation of the thrust rod (6) effects axial translation of the pin (11) to actuate the vacuum cup (12 ). The camming surface (9) does not interact with slot (13).

A mounting plate secured to the instrument and a cooperating base plate are provided with juxtaposable mating surfaces, preferably flat, and a pair of dowel pins protruding from one plate are aligned to be seated in beveled, countersunk holes formed in the other plate, while a quick latch device anchors the two plates in aligned, mated juxtaposition.

Abstract: The disclosed bracket is attachable to an outrigger of a mobile home and is adapted to mount a service closure containing the protector device in a telephone lead-in connection to the home. The bracket comprises: a longitudinally extending base securable by beam clamps to a flange on the outrigger, a longitudinally extending plate disposed transversely to one side of the base and adapted to have the service closure mounted therein, an adjustable length strut means pivotally connected at opposite ends to longitudinally central parts of, respectively, the base and the plate, and first and second base-to-plate fastening means providing alternatively usable first and second pivotal couplings of the base and plate at locations longitudinally spaced from and on opposite sides of the couplings of such strut means to these elements.

Abstract: A pipe-supporting device adapted to receive and support an exposed pipe on a roof has a substantially flat bottom for resting on the roof and an upwardly tapered structure secured on and rising from the base to provide a pipe positioning and supporting structure which substantially equally distributes the weight of the supported pipe over the area of the base in contact with the roof. The pipe positioning and supporting structure has a pocket for positioning a pipe therein and the pipe is supported in the pocket by at least one roller positioned in at least one receiving trough. As the pipe expands or contracts, it rides on the roller which rotates within the trough.

Abstract: A quick disconnect assembly (20) provides for the releasable attachment of a fixture, such as a helicopter seat frame (26), to a support structure, such as the interior structure of the aircraft cabin (28). The assembly includes a tie down stud (100) having a substantially spherical outer surface (182) and a threaded bolt (188) extending therefrom for attachment to the support structure. An attachment fitting (22) is provided having a main body (40) with means for attachment (56) to the fixture. A plurality of grip arms (148) are pivotally associated with the main body. The arms have inwardly curved ends (156) for cooperating with the spherical outer surface of the stud to engage the stud by positioning the arms inwardly. With the attachment fittings secured to the tie down stud, the attachment fitting is movable relative to the stud through a predetermined angle.

Abstract: The invention contemplates a unitary cable-clamp fitting adapted for clamped above-ground suspension of a cable from a telephone pole or the like. The fitting comprises two elongate side panels integrally connected by an elongate single bend, establishing an initially acute angle between the side panels. The outer longitudinal edge of each panel is characterized by an elongate flange bent inward and generally toward the opposed side panel, at an acute angle to its associated side panel. The initial space between flanges is slightly less than the cable diameter to be accommodated, so that cable assembly and loose retention are achieved via snap-action insertion between the flanges. Bolts spanning aligned apertures in the side panels enable secure clamping to, and lug-retention against loss of, an inserted cable.
