Patent number: 5896608Abstract: The invention relates in part to a method of constructing a lasting board with contiguous attachment points. A flexible shoe lasting board is formed with extensions beyond the feather edge of the last. The extensions are coextensively formed with the lasting board since they are cut as a single unit from one sheet of material. This method of construction provides greater integrity of the joint between board and extensions than would be present if attachment was required, such as by stitching or cementing. The extensions of the lasting board are useful for securing the shoe to the foot and for securing components to the lasting board.Type: GrantFiled: March 7, 1997Date of Patent: April 27, 1999Inventor: Ian H. Whatley

Patent number: 5729918Abstract: A method of lasting an article of footwear includes forming a pattern for a shoe upper from a first material, forming a pattern for a lasting sock from a second material, and stitching a perimeter of the lasting sock to a bottom edge of the shoe upper. The stitching extends from a first location rearward of an arch area of the shoe upper, around a heel area of the shoe upper, along a lateral side of the shoe upper, around a toe area of the shoe upper, and terminates at a second location forward of the arch area of the shoe upper such that the arch area remains unstitched. An adhesive is applied to the arch area of the shoe upper and it is thereafter adhered to the lasting sock.Type: GrantFiled: October 8, 1996Date of Patent: March 24, 1998Assignee: Nike, Inc.Inventor: Ben Smets

Patent number: 5678269Abstract: A machine for lasting the toe and side and heel of an upper to an insole mounted to a last includes a toe and ball wiper assembly and a heel and shank wiper assembly in combination with a pincer assembly mechanism for stretching the upper tightly about the last and a toe clamping mechanism for clamping the stretched upper against the last. Following stretching and clamping, the toe wipers are actuated to press the upper margins against the insole bottom against the counter force of an overhead toe hold-down acting against the top of the upper. A brake mechanism fixes the overhead hold-down to maintain the toe wiping plane in a constant position. The heel wiper assembly is elevated within the machine to locate the heel wiper plane at a proper height relative to the insole bottom, the proper height being determined with a sensor mounted for movement with the heel wiper assembly. A heel clamping pad assembly connected to the heel wiper assembly then clamps the heel prior to stretching of the upper.Type: GrantFiled: February 2, 1995Date of Patent: October 21, 1997Assignee: International Shoe Machine CorporationInventor: William Walega

Patent number: 5659914Abstract: A method for construction of waterproof footwear includes providing an upper defining an internal volume for receiving and protecting a wearer's foot against external elements, lasting and securing an inner liner having a waterproofing layer within the internal volume of the upper, securing the inner liner at a lasting edge portion of the liner to an insole having an external surface, securing a gasket element over the lasting edge portion of the liner and external surface of the insole, lasting the upper over the inner liner, and securing an outsole to the lasted upper. Performing two independent lasting operations ensures that during use, even if water somehow penetrates the upper, the lasted inner lining provides independent protection to the wearer's foot.Type: GrantFiled: October 5, 1995Date of Patent: August 26, 1997Assignee: H.H. Brown Shoe Company, Inc.Inventor: Fred A. Steinlauf

Patent number: 5152025Abstract: A method and injection mold assembly for making open-heeled shoes as disclosed. A lasting string is wrap-stitched around the lower peripheral border of an upper having an open heel, and the wrap-stitching is reinforced. The upper is aligned upon a last and the lasting string is tightened such that the upper fits tightly on the last. Preferably, a teflon edge projects out from the last in a location corresponding to the superior edge of the sole in the open heeled area to protect against leakage during injection molding.Type: GrantFiled: May 18, 1989Date of Patent: October 6, 1992Inventor: Sergio Hirmas

Patent number: 4924546Abstract: The pulling over assembly (2, 39) and lasting assembly (13, 40) of a pulling over and lasting machine are capable of being moved apart to enable a pulling over operation to be effected on one shoe at a first station (I) while a lasting operation is being completed on a further shoe at a second station (II). In one embodiment the pulling over assembly (2) moves bodily to the second station (II) at which the lasting assembly (13) is arranged; in a second embodiment the lasting assembly (40) moves to the first station (I) at which the pulling over assembly (39) is arranged. Each assembly (2, 13; 39, 40) has a heel rest (5, 19; 41, 50), the heel rests being so arranged as to carry out without collision the function of holding the shoe against lengthwise displacement.Type: GrantFiled: September 20, 1988Date of Patent: May 15, 1990Assignee: DVSG Patentverwaltungs GmbHInventors: Frank C. Price, Gerhard Giebel, Rudi Fichtner, Manfred Broening
