Abstract: A support pad apparatus, including a rigid platform and a load-spreading conformable pad thereunder that conforms to the bottom surface of the platform and may either be flat or concave along its bottom surface to engage the surface of a flat, uneven or sloped roof or some other type of flat, uneven or sloped hard or soft underlying surface, both within and outside of a building, or in any other appropriate setting. The top of the platform contains the structural means to ensure that the person working, standing or walking upon the platform is able to maintain a secure, stable, and balanced footing.

Abstract: An improved device for collecting and removing debris from a swimming pool, pond or the like comprising a mesh material formed into a net for collecting and temporarily storing the debris. The net includes a top open portion with a support frame and a bottom closed portion forming a vertex. A pole or extensible rod is attached to the end of the frame for holding and manipulating the device through the water. Also provided is a means connected to the bottom closed portion of the net enclosed within the netting to maintain the vertex portion of the net in an open and receptive position while it is manipulated and moved along and below the water's surface to collect and remove debris. The means, when rotated to a horizontal position, expands the bottom closed portion of the net to facilitate the collection of debris and is also used as a device for grasping the bottom closed portion of the net in the process of emptying the net of debris.

Abstract: A device for use with a skateboard and a skateboard truck assembly to facilitate the removal and replacement of various component parts of a skateboard truck assembly including the bushings and the tension bolt, which is used to join the base plate and the axle assembly. The bolt, which is inserted through the aligned apertures in the axle assembly and the base plate, penetrates into the area beneath the base plate where it emerges and mates with the threaded nut. The device is supported by the bottom surface of the board and held stationary inside a pocket formed within the underside of the base plate and consists of integrally formed components including a generally flat base, a sloped guide platform situated upon the base, and an upstanding heel section formed at the base of the sloped guide platform. The guide platform is constructed according to a specific angle of inclination to fix the nut's orientation and to enable the nut and the threaded end of the bolt to properly align and engage.

Abstract: A device for use in combination with a musical drum for dampening extraneous and undesirable tones produced by the drumhead consisting of a means for affixing the device to the drum, such as, for example, a clamp assembly, mounted on a counterhoop. Connected to the clamp assembly is an L-shape bracket, which extends generally above the clamp and over a section of the edge portion of the drumhead surface where it attaches in pivotal relation to a horizontally extending arm, which is connected on its opposite end to a casing. An aperture is formed within the casing and extends entirely from the top end of the casing to the bottom. A vertically disposed plunger arm is slidably received through the aperture, and is connected at the bottom end to a plunger head, which includes a base portion and a felt pad or some similarly suitable material mounted thereon to act as the contact surface with the drumhead.

Abstract: A drumhead lamination comprising upper and lower layers of synthetic plastic sheet materials and a layer of impregnated polyester or natural fabric sheet material sandwiched in between the systhetic plastic layers. A substance employed to impregnate the fabric, typically a liquid resin, causes the fabric to harden and stiffen to enable it to vibrate synergistically in concert with the vibrating synthetic plastic layers when the drumhead is struck by a drumstick or a similarly hard object. Laminating adhesive is used to bond the layer together. Epoxy or a similar substance is applied to the top and bottom exposed surfaces of the drumhead as a protective coating.

Abstract: A device comprising a generally cylindrical shaped resilient cover with openings at opposite ends to receive in slidable relation the elongated rod component of a drum lug nut assembly. A slit is provided in combination with one of the openings to enable that end of the cover to expand and connect with the portion of the rod extending either below or above the nut component, as the situation requires. A portion of the back section of the cover is open to enable the cover to easily fit over and around the nut and the other components of the drum lug nut assembly that protrude beyond the surface of the drumshell.

Abstract: A head of a drum or similar kind of musical instrument comprising a synthetic plastic sheet material containing surfaces with variegated color shadings to give the texture and appearance of a natural animal skin. A method of manufacture of the improved drumhead including the steps of fine sanding to produce minor surface scratches, and intensive sanding to produce deeper scoring or gouges in the top and bottom surfaces of the head. A coating of resin is applied to the surfaces and collects within the scratched and gouged areas to produce the variegated characteristics of a natural skin and manipulate the surface structure to provide vastly improved sound.
