Abstract
A combined apparatus for repelling birds from undesirable locations such as airports and critical adjacent airspace, while detonating used squibs for safety. A mobile, wheeled cabinet houses the components. An internal vise for temporarily securing squibs for preparation. Prepared squibs may be held internally of the cabinet with an internal multi-squib detonation fixture comprising a plurality of spaced apart mounting rings into which squibs may be coaxially received for firing. The mounting rings secure the squibs with peripheral wing nuts that are tightened to secure the squibs. A remote control circuit providing electrical power first illuminates a warning light in response to the actuation of an external, rotatable handle. The circuit is then remotely triggered for squib firing. In response to detonation, explosive gases are vented through discharge pipes, and considerable noise is directed outwardly towards a target area.

1. A device for concurrently repelling animals while detonating used squibs, the device comprising: a rigid, wheeled for enclosing and transporting components of the device, the cabinet comprising an interior; an electrical circuit for powering the device and controlling squib detonation; at least one blast discharge tube for venting the cabinet interior and outputting noise in response to squib firing; an externally actuated on-off switch mechanically actuated by a handle projecting exteriorly of the cabinet for powering the circuit; a multi-squib detonation fixture for holding multiple squibs for firing; and, an actuator for instructing the circuit to fire one or more squibs.
2. The device as recited in claim 1 wherein the squib detonation fixture comprises a plurality of spaced apart mounting rings for receiving and mounting squibs to be fired.

DETAILED DESCRIPTION OF THE DRAWINGS
[0037] Turning initially now to FIGS. 1-3 2 of the appended drawings, my new Combined Squib Disposal and Bird Repellent Box has been generally designated by the reference numeral 10. The invention comprises a preferably metallic, rigid cabinet 12 that is generally in the form of a parallelepiped. Cabinet 12 comprises a pair of spaced-apart and generally parallel end panels, one of which is seen in FIG. 1 and designated with the reference numeral 15. Cabinet 12 comprises a displaceable cover 13 upon which a bright, electrically powered warning light fixture 14 flashes during use and prior to firing for unmistakably indicating the firing state of the invention. The cabinet 12 is preferably supported upon a plurality of transport wheels 11 for locomotion.
[0038] Each cabinet end panel such as panel 15 supports a convenient, pivotal handle 18A supported by hinges 19A for aiding in the maneuvering and relatively small displacements of the device. In addition there is a larger handle 18B that may be removably coupled to receiver 19B forming an approximately forty-five degree angle as in FIG. 2, or which may be telescopically received within a lower passageway 19C (FIG. 2) to orient it flatly in an out-of-the way position that is generally parallel with the ground.
[0039] Panel 15 also supports an electrical on-off switch 20 that is mechanically actuated by a rotatable handle 22 for placing the device 10 in a ready state. A typical key-operated switch may be used for switch 20. Switch 20 and light fixture 14 are connected to wiring disposed within the cabinet 12 as seen in FIG. 9 and explained below. Visible in FIG. 3 are a pair of parallel and spaced apart blast discharge tubes 30 and 31 explained hereinafter that are disposed on the opposite side of the cabinet 12. Tube 30 is secured to a discharge orifice 30A seen in FIG. 2). Tubes 30 and 31 connect the cabinet interior in fluid flow communication with the outside.
[0040] The cabinet 12 encloses a generously sized, somewhat cubical interior 10A in which wiring and various components are mounted. The switch 20 closes or opens a pair of power lines 34 and 35 respectively (FIG. 4) ultimately energized by a battery within battery housing 102 (FIGS. 4, 9) through a remote electrical switch box 44. Power supplied by the battery system and activated by switch 20 via its control circuitry will be directed through the switch box 44, activating the warning light fixture 14 and preparing for firing.
[0041] A locking system is provided. In FIG. 1, the rear ends of a pair of spaced-apart, conventional padlocks 40 are seen. These key-operated padlocks are nested through suitable orifices within the cabinet, and their shackles 41 enter the cabinet interior, as illustrated in FIG. 4, and engage a locking bracket 42.
[0042] Referring mainly to FIG. 7, the cabinet interior 10A houses a squib vise 60 that comprises a pair of compressible jaws 70 and 71 that are activated by a rotatable vise handle 75 (FIG. 5) that rotatably displaces threaded rod 76 that is threadably directed through block 74. When the jaws 70, 71 are suitably compressed, a live single squib 80 may be temporarily captivated by the vise 60 for forcibly removing certain packaging and parts from the active element. Activation wires 72 that may terminate in alligator clips 73 for attachment to squib terminals to fire the retained squib 80. The frame of vise 60 is adjustably, slidably mounted by fasteners 86 that track within follower slots 84, engaging a header (not seen) within cabinet 12. Vise 60 is disposed adjacent a rigid, multiple squib detonation fixture 65.
[0043] The multi-squib detonation fixture 65 (FIG. 8) is used to controllably fire and disarm multiple squibs of average size. The multi-squib detonation fixture 65 may be removed if a squib is of an abnormal size (larger), and the larger squib may be directly held with the vise 60 (FIG. 7). The metal squibs will be loaded and ultimately fired as is typical in aviation.
[0044] Referencing FIG. 6, a typical squib assembly 90 comprises a substantially tubular, body with an explosive region 96 bounded by an outwardly projecting electric terminal 97. Suitable wiring connected to terminal 97 can fire the squib.
[0045] With primary reference now directed jointly to FIGS. 5 and 8, the squib detonation fixture 65 comprises an elongated, rigid frame 89 adapted to be secured for use by a pair of spaced apart flanges 92 and 93 (FIG. 8). The fixture's flanges 92 and 93 are oriented forty-five degrees relative to the floor of the cabinet. Frame 89 (FIG. 8) mounts a plurality of spaced apart mounting rings 95, each of which has a pair of radially spaced apart wing nuts 97 projecting from its periphery. Squibs to be fired are retained until discharged within the rings 95, being frictionally secured by appropriate tightening of the wing nuts 97. The vise is designed to either hold a single large squib or be able to hold multiple squibs as in FIG. 8. When firing occurs, explosive gases are discharged through pipes 30 and 31 (FIG. 3), causing considerable noise. Wires 91 fire the squibs.
[0046] Referencing FIG. 9, the circuit for operation and control has been generally designated by the reference numeral 100. Twelve-volt DC. power is applied from battery 102 through an SPST switch 104 driven by handle 22. When switch 104 closes, incandescent bulbs or LED's 106 disposed within light fixture 14 (FIG. 1) illuminate. Electrical switch box 108 energizes one or more squibs, designated 109, 110, 111, and 112. Switch box 108 is remotely controlled by wireless remote 114.

[0048] Further, it will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and sub combinations.
[0049] As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
