Abstract: An easy to assemble mechanical apparatus and methods that create a barrier for deterring birds from landing at or near undesirable perching locations. The barrier is created by a rotating carriage that is propelled in a rotational motion by the wind or an available draft of air. A first embodiment utilizes a rotatable carriage which is an assemblage of individual parts that form one unified rotating body which rotates on antifriction bearing surfaces with horizontally disposed rods extending radially outward therefrom. A second embodiment utilizes a pivot pin which supports the rotating carriage portion and is designed to be placed in a variety of locations by an easy-to-use locknut and groove system. A quick action push-nut, or other means for securing, secures the rods or means for creating a barrier onto the carriage. The carriage rotates about the pivot pin with a multiplicity of rods or a means for creating a barrier extending out to any desired length and at any angular disposition from the carriage.

Abstract: A bird deterrent device and method which combines the deterrence of an inanimate bird deterrent device with the erratic behavior of a movable deterrant device without injury to the brids or the use of sharp and portions. The present invention uses a multiplicity of projecting members which radiate out from a flange and base that is secured to a bird perching area. The projecting members may be aligned in a coplanar fashion with the flange so as to be suited to deter birds from perching on narrow building ledges or the wires may extend outward in different planes. The projecting members are of sufficient length so as to be visibly disturbed by an available draft of air but are not strong enough to support the weight of a perching bird. The physical presence of the device and the erratic independent movement of the projecting members, with the resulting physical obstruction so created, deter birds from perching at or near the device.

Abstract: Improvements to a bird deterrent apparatus comprising a coiled wire in which the wire is attached to an elongate strip having flaps punched therein which are bent and crimped over the wire to hold it in position, and a spring having bent end loops used to connect adjacent ends of the wire together.

Abstract: The device wherein the second, minute or hour stem of the conventional quartz clock movement is used to provide a motive force for continuous rotation, for use in ornamental or advertising displays and the like. The quartz movement mechanism is housed in a base structure or frame. A system of counterpart magnets, one counterpart being attached to the stem of the clock movement within the base structure or frame, the other counterpart magnet attached to the rotatable display structure which is caused to pivot such that the magnets are situated sufficiently close to one another so that rotation of the stem is communicated to the display structure.

Abstract: An ornamental clock operates while submerged in a body of water, the clock having a clock face and relatively movable hands and a mechanism for moving the hands. Air bubble receivers are each mounted for movement between a first position to entrap air bubbles and a second position to release air bubbles into the water. Spaced ports deliver air into the water below each bubble receiver. Accumulation of bubbles alternately in each receiver produce buoyant forces which act through linkage to drive the clock mechanism. Apparatus is provided to deliver air alternately into the ports.

Abstract: A liquid operated clock employs buckets pivoted to arms of a carrier rotating at constant speed. The buckets are sequentially moved below the surface of a liquid reservoir to fill the buckets, elevate them and cause them to discharge into a receiver. After a predetermined number of buckets of liquid have accumulated within the receiver, it is suddenly drained by a siphon tube back into the liquid reservoir. The change in weight of the receiver between full and empty conditions operates through a ratchet mechanism to drive the input shaft of a clock mechanism in an intermittent fashion. Cam and follower means control filling and dumping of the buckets.

Abstract: An ornamental lamp employs one or more upward extending transparent tubes containing an electrically non-conductive liquid under a partial vacuum. A heater at the lower end of each tube causes bubbles to form and to pass through a restriction and to ascend in the liquid. A series of electric lamps are spaced at intervals within the tube above the restriction. The lamps supply additional heat as the bubbles ascend to prevent condensation of the bubbles. The lamps also illuminate the bubbles. A pleasing twinkling effect is produced as each bubble passes one of the lamps.
