  • Drum support apparatus
    Patent number: 3994053
    Abstract: A drum support apparatus including outboard and inboard hubs having outer surfaces adapted for interface fitting with the inside surface of a drum. The hubs while being supported on a shaft that is cantilevered from a frame, provide support for the drum in the form of a plurality of spaced equidistant lobes located on their outer surfaces. The lobes reduce the load required to properly seat the drum against the hubs and thereby decreases the possibility of drum run-out by reducing the contact area when the interface fit of the drum/hub combination occurs. The shaft is supported at its outboard end by a removable support bracket.

  • Mechanism for adjustably positioning an embroidering frame
    Patent number: 3991691
    Abstract: Stepping mechanisms are used to move an embroidering frame in both the vertical and horizontal directions on a machine frame. Each stepping mechanism includes a hydraulic cylinder-piston rod assembly, a multi-way valve for directing the flow of hydraulic fluid to the assembly, and an electric stepping motor connected to the valve for regulating the flow to the assembly. To effect movement a signal is transmitted to the stepping motor which positions the valve to operate the hydraulic cylinder-piston rod assembly. The piston rod is in direct contact with the frame and its movement provides the desired movement of the embroidering frame. The piston rod is connected to the stepping motor for closing the valve when the desired position of the embroidering frame has been reached.

  • Manufacture of safety shoes having rigid box toes
    Patent number: 3986279
    Abstract: A safety shoe having a rigid box toe (such as steel) is assembled by a method in which the steel box is incorporated into the shoe upper before the upper is assembled with the last. The steel box is attached to the upper in a position such that when the upper assembly (including the steel box) is fitted onto the last, a light longitudinal draft of the upper will result. With the upper thus placed on the last, it can be lasted in conventional pulling over and lasting equipment. The upper assembly has only one lastable marginal portion at its toe and forepart region so that only one pulling over and lasting operation is required in order to last the upper about the box toe.
