Patent number: 4489876Abstract: A compression mold includes punch and cavity components fabricated from initially flat sheets of relatively thin metal. The sheets of each component are shaped, assembled and joined to provide box-like components defining mating mold surfaces yielding molded parts which may be straight or laterally and/or vertically curved. The hollow interior of the two components allows for the circulation therethrough of an appropriate heat transfer medium to permit molding of either thermosetting or thermoplastic compounds.Type: GrantFiled: March 29, 1983Date of Patent: December 25, 1984Assignee: Kidde Recreation Products, Inc.Inventors: Leonard S. Meyer, Michael J. Murray, Gerald G. Hayes, Robert L. McClain

Patent number: 4475723Abstract: An elongated spring member is formed of fiber reinforced plastics, particularly resin-impregnated glass fiber strands, and includes end provisions adjacent the two ends for the reception of attachment elements associated with the use of the spring. The spring includes parallel impregnated strands which have been wound about a rack provided with end supports following which the entire wound resinous product is placed within a mold cavity and cured to provide a spring member having integral, molded end provisions encircled by continuous, uncut reinforcing fibers with or without the inclusion of additional reinforcing material, and which is molded without the formation of any significant waste product. The improved spring member includes transversely disposed end provisions which may comprise a passageway or elongated end members encircled by the reinforced strands and the center axis thereof may be along the neutral axis of the spring body or alternatively, above or below the neutral axis.Type: GrantFiled: April 28, 1982Date of Patent: October 9, 1984Assignee: Kidde Recreation Products, Inc.Inventor: Leonard S.

Patent number: 4415061Abstract: A portable step assembly for attachment to a tree or pole includes a generally L-shaped climbing member and a separate, headed fastener member. The fastener member is removably insertable through a mounting portion on the climbing member after which the climbing member is employed as a crank tool to drive the fastener member into the tree. A specially configured socket recess or cavity within the mounting portion captively receives the screw member head and serves two primary purposes. First, it allows a one-handed push upon the assembly during the initial drive of the fastener member and secondly, dual sets of shoulders within the socket cavity form positive abutments to screw or unscrew the assembly respectively during its attachment or removal from a tree.Type: GrantFiled: September 1, 1982Date of Patent: November 15, 1983Assignee: Victor United, Inc.Inventor: Leonard S. Meyer

Patent number: 4352769Abstract: A plurality of reinforced plastic parts are simultaneously molded from separate bundles of resin impregnated strands wound about individual frame sections of a substantially planar frame assembly. A loading station includes a dual-acting elongated carrier engaging the multi-sectioned frame assembly and initially rotatable to wind the bundle of strands thereon. Subsequent reciprocation of the carrier delivers the wound frame assembly to a molding station provided with a plurality of mating pairs of mold sections and having displaceable frame supporting and bundle clamping assemblies for engaging the wound frame assembly and severing opposite ends of the bundles as the mold sections close within the individual frame sections. Upon opening of the mold sections, molded parts and the empty frame assembly are subsequently shuttled from the molding station by a removal station provided with a reciprocating elongated carrier axially aligned with the center line of the molding station and the loading station carrier.Type: GrantFiled: March 31, 1981Date of Patent: October 5, 1982Assignee: Victor United, Inc.Inventor: Leonard S. Meyer

Patent number: 4318762Abstract: A reinforced plastic product is molded from a bundle of resin impregnated strands with the bundle being sequentially advanced from a supply station to a molding station by two pairs of clamping assemblies simultaneously reciprocating in opposite directions with the forward moving pair gripping the bundle and pulling it to the molding station as the rearward moving pair is shuttled back past the forward moving pair toward the supply station to grip the bundle prior to molding of the forward gripped bundle.Type: GrantFiled: April 21, 1980Date of Patent: March 9, 1982Assignee: Victor United, Inc.Inventor: Leonard S. Meyer

Patent number: 4235444Abstract: A target made of interchangeable sections each comprising a multiplicity of membranes or plies of penetrable, elastomeric or resistant, tear resistant sheet resin material, the membranes being separated by intervening layers of porous or low density, resilient material such as foam resin material. Membranes are disclosed having opposite surfaces with different coefficients of friction.Type: GrantFiled: September 11, 1978Date of Patent: November 25, 1980Inventor: Leonard S. Meyer

Patent number: 4081302Abstract: There is disclosed a method and apparatus for making tubular fiber reinforced thermosetting resin elements having a thermoplastic lining. The technique involves application of a thermoplastic lining layer to an axially moving mandrel surface, application of at least one layer of fiber reinforced thermosetting resin material superimposed upon the lining layer, providing for bonding of thermosetting and thermoplastic layers to each other, and heating the thermosetting resin to effect solidification during axial advancement of the superimposed layers with the moving mandrel surface. Provision is also made for applying a thermoplastic jacket layer superimposed upon the thermosetting layer.Type: GrantFiled: June 21, 1976Date of Patent: March 28, 1978Assignee: Frede Hilmar DrostholmInventors: Frede Hilmar Drostholm, Leonard S.

Patent number: 4028460Abstract: A grating comprising preformed fiber reinforced resin strips stacked in the positions of the intersecting bars of the grating and with the strips interleaving at the points of intersection, the reinforcement strips being embedded in a resin matrix. The method for making the grating comprises forcing the fiber reinforced strips with the fibers under tension, and assembling such preformed strips in a mold having a network of intersecting cavities for defining the grating bars, the cavities being initally charged with liquid hardenable resin material, so that the reinforcement strips are submerged in the liquid resin during assembly, the embedment resin being subsequently hardened.Type: GrantFiled: June 21, 1972Date of Patent: June 7, 1977Assignee: Sybron CorporationInventor: Leonard S. Meyer

Patent number: 3965883Abstract: An archery bow is disclosed having a handle section and recurved limbs, the recurve of the limbs being substantially greater than has been practicable heretofore, the limbs being thick and formed of an elastic material having a minimum elongation of 4% and a maximum tangent flexural modulus of elasticity of 2,000,000 p.s.i., thereby providing a bow having exceptional twist resistance, notwithstanding the extent of recurvature of the limbs. Additional twist resistance is provided by elevated string guides. Embodiments are also disclosed providing for adjustment of the recurved limbs with respect to the handle section of the bow. A novel method for manufacturing the improved bows is also disclosed.Type: GrantFiled: August 9, 1972Date of Patent: June 29, 1976Inventor: Leonard S. Meyer
