Publication number: 20200368754Abstract: A plant material trimmer (PMT) that cuts/separates plant leaf material from plant flower material. The PMT has a trimming assembly that includes a motor with a shaft. A propeller is attached to the motor shaft, above the motor. A twisted metal stand wire rope cutting element is attached to the propeller. An upward extending pin is located at each end of the propeller and the cutting element's ends interface with the pins. A trimming platform is located above the trimming assembly. The platform has multiple elliptical beveled slots extending therethrough. Above the platform is a conveyor assembly with a belt that rotates about two axles. A plurality of push panels are attached to the belt. A conveyor motor produces a forward movement of the belt and push panels which sweep across the platform. Wet or dry plant material is placed on the platform, and the push panels sweeping across the platform cause the plant material down through the slots.Type: ApplicationFiled: May 20, 2019Publication date: November 26, 2020Inventor: Richard D.

Patent number: 8981194Abstract: A drumstick that is produced from a pair of bonded wooden halves that form an elongated, structure having a circular bore therethrough. Into the circular bore is inserted a core tube that increases the rigidity of the drumstick, a multiplicity of glass micro-spheres that function to reduce drumstick vibrations that can affect a drummer, and a resilient sleeve that is inserted over the front end and partial rear end of the drumstick. The resilient sleeve increases the useful life of both the drumstick and the instrument struck by the drumstick.Type: GrantFiled: April 23, 2013Date of Patent: March 17, 2015Inventor: Richard D. Grossman

Publication number: 20140366706Abstract: A percussion instrument dampening pad (PIDP) that is designed to be attached to the vibrating surface of a drumhead, a drum, a cymbal or the like. The PIDP functions by reducing unwanted vibrations and overtones that occur when the drumhead or cymbal is struck. The PIDP is comprised of at least one composite upper section, a first vibration absorbent layer preferably comprised of polyurethane puron foam, and a second vibration absorbent layer preferably comprised of butyl rubber that is in contact with the vibrating surface of the drumhead, drum or the cymbal. The composite upper section is further comprised of a metallized layer, a fabric layer and an adhesive layer. The PIDP also includes indicia and a removable liner that is removed prior to attaching the exposed butyl rubber to the surface of a drumhead or the like.Type: ApplicationFiled: June 13, 2013Publication date: December 18, 2014Inventor: Richard D.

Patent number: 7387302Abstract: An ice skate comprising a blade and a blade holder. The blade holder providing decreasing, non rigid, and/or no lateral support in a rearward region of the blade so that it may facilitate increased or freer flexibility of the blade and improved maneuverability. The blade is rigidly laterally supported at a front end section of the blade holder and preferably also at a back end section of the blade holder so that it may facilitate efficient transfer of force between the skater and the blade. One or more non-rigid support members may be employed to control, absorb and/or cushion the flexing of the blade. The ice skate may be tuned to reflect the desired performance requirements of the individual skater and/or use.Type: GrantFiled: February 17, 2006Date of Patent: June 17, 2008Assignee: Easton Sports, Inc.Inventors: Edward M. Goldsmith, Richard D. Grossman

Publication number: 20040061300Abstract: A skateboard assembly includes a platform or board, a plurality of spaced wheel axles and pivotally secured set of arms connected to the frame at opposite ends of the skateboard. The truck suspension system provides shock-absorbing capabilities and includes an improved shock-absorbing system that can be easily interchanged to create a desired amount of shock-absorbing capability for the skateboard. The shock-absorbing system includes an outer shock member which encases at least one shock-absorbing insert. These shock-absorbing components are placed between each arm of the truck assembly and the board to absorb shock. The shock-absorbing insert is interchangeable so that the amount of shock absorption can be changed depending upon the rider's weight or to attain a particular ride feel. A quick release strap-down system utilizes hook and loop fasteners to create a system for easily and quickly interchanging the shock-absorbing components.Type: ApplicationFiled: December 19, 2002Publication date: April 1, 2004Inventor: Richard D. Grossman

Patent number: 5964469Abstract: A roller skate wheel is described wherein the weight of wheel is significantly reduced by employing a bushing bearing instead of the usual ball bearing in at least one side of the wheel. The bushing is formed of Peek material so as to provide the necessary strength and low friction necessary to provide desirable skating characteristics.Type: GrantFiled: April 24, 1997Date of Patent: October 12, 1999Assignee: Jas.

Patent number: 4645223Abstract: The assembly includes a skateboard, a plurality of spaced wheel axles and rotatably secured sets of wheels and elongated resilient suspension frames connected at their opposite ends through housings to the wheel axles and to the underside of the skateboard. The assembly has at least four different shock-absorbing systems. Thus, the frames themselves absorb shock, as do cylinders of resilient rubber or the like set in cups connected to the frames above the wheel axles and bearing against the underside of the board. The wheel axle housings also include resilient dampeners which adjustably restrict steering rotation of the wheel axles and additionally dampen shocks. The frame housing connected to the underside of the skateboard rotatably receives the bases of the frames and adjustably controls that rotation, while providing a shock absorbing function, through the use of resilient bushing around the frame bases.Type: GrantFiled: February 21, 1985Date of Patent: February 24, 1987Inventor: Richard D.
