Abstract: A tunable drum is shown having a hollow drum shell, and imperforate drumheads closing the ends of said drum shell. One or more opening extend through the drum shell for acoustic venting, and valves are provided for adjusting the size of the openings to vary the amount of acoustic venting, and consequently the volume, pitch, tone, timbre and stick response of said drum. The valves may be slide valves movable, e.g., slidable or pivotable, between an open and a closed position. A preferred valve consists of a ring member positioned for rotation inside said drum and slidable endwise of the drum to cover or uncover said drum openings, or the ring member may have openings that match the drum openings and operable to cover or uncover the openings or rotation. A handle for rotation of the ring member extends outside the shell for movement by the drummer.

Abstract: Drum hardware and drum secured thereon are preferably supported on a vest type carrier or a T-bar carrier having a plurality of separate parts removable from each other and formed of a rigid plastic, light metal such as magnesium, aluminum or titanium. The removable hardware includes a removable back support member. The removable back support member consists of hardware or configuration that can be removed or securely attach to the carrier with or without tools. The back member may be adjustable in width using slotted holes, telescoping components or sliding members. The adjustment to the back support member can be performed by adjusting the shoulder straps. The back member may be secured to changeable and or adjustable shoulder straps.

Abstract: A drum assembly has a hollow drum shell with a drumhead and drum rim closing one or both end thereof and a guard member secured on one or both drum rims. The guard member is a sleeve member fitting over one or both edges of the drum dim and is secured thereon by setscrews or bolts and locknuts.

Abstract: A portable griddle stove has two non-stick cooking surfaces, either of which can withstand being on the underside of the cooking surface in use and the heat applied to the underside surface. A heat shield and heat diffuser control the temperature applied to the underside of the cooking surface by providing radiant heat to the center portion of the cooking surface and cooling the combustion gas diffused to the perimeter of the cooking surface. Secondary air provided through openings in case the and heat shield assist in cooling the combustion gas.

Abstract: Apparatus is disclosed for carrying percussion instruments, particularly drums of various kinds, which comprises a combination of a carrier assembly with a novel receptacle for supporting J-rods thereon. The carrier is a vest-type or T-bar-type carrier with clamps for tubes or J-rods having a base and overlying portion configured to engage the tube or J-rod at a plurality of distinct and separate points. Variations are shown which have one or more clamps on a single base. In other embodiments, a plurality of clamps are adjustably positioned on the carrier.

Abstract: A heater provides both radiant heat and light. The heater provides radiant heat via a heater assembly which includes a gas burner heating a screen; the screen in turn provides radiant heat. The heater includes a light assembly which may provide light by, for example, burning gas fuel, or by other means such as electricity. The heater may include a heat reflector which can be removed and compacted or disassembled for storage. The light assembly may include easily removable glass panels surrounding the light source. Each glass panel is mounted to the lighting assembly by tabs extending from the bottom of the glass panel and a thumbscrew connection attaching the top portion of the glass panel to the lighting assembly. Hot exhaust gasses generated by the lighting assembly may escape through vents near the top of the lighting assembly, below the heating assembly.

Abstract: A gas operated lantern includes a control mechanism whereby a user may start gas flow through the lantern, operate a choke, and ignite the lantern. The user may perform these operations using the same control in an easy, simple series of motions. The user may rotate a knob, rotating a stem, to start gas flow and press the knob axially inward along the stem to operate a choke and an igniter.

Abstract: A portable heater assembly includes a fan module, an electrical ignition assembly, a heating apparatus, and an encasement. The encasement supports and houses the fan module, the electrical ignition assembly, and the heating apparatus. The fan module includes a fan, an electric switch, and electrical wiring, the electrical wiring interconnecting the fan, electric switch and a power source. The electric switch activates the fan by forming a closed electrical circuit within the electrical wiring between the power source and the fan. The electrical ignition assembly includes an electrical ignition device, a spark-emitting electrode tip protruding from the electrical ignition device, and an ignition activator connected to the electrical ignition device by an activator connector.
