  • Patent number: 4272858
    Abstract: A moccasin shoe is proposed to be made by a method which comprises cutting the parts of an upper including a vamp, preparing the underside of the vamp for fusing, assembling the back part of the shoe, placing and fixing the thus formed and prepared upper, which does not include a plug, in a mold which is injected with polyurethane or other suitable thermoplastic material to form a sole which is bonded to the underside of the upper and also, by means of an upstanding peripheral flange to the side margins of the upper, removing the upper from the mold and thereafter stitching a plug portion to the upper margin of the vamp.

  • Patent number: 4272897
    Abstract: A shoe shank support suitable for being molded into a unit sole for a ladies high heel shoe provides increased stability and resistance to flexing and comprises a shank of metal strapping sufficiently long to extend from the heel area to approximately the beginning of the ball of the foot and a heel post which extends the height of the heel. The shank may be generally flattened and include a strengthening rib or it may be oval in shape. The heel post is attached to the heel area of the shank by being inserted through a hole and tightened in position by a reversed wing nut. The threaded end of the heel post extends the length of the heel and protrudes a small distance therefrom to provide a mounting for top lifts on the bottom of the heel. Additional holes may be provided in the shank for positioning the shank in a mold and preventing slippage of the shank during the molding process.

  • Patent number: 4272859
    Abstract: The present invention relates to a method for making an overshoe made of non-woven fabric, wherein a blank is used, constituted by two identical sheets in the form of a parallelogram and connected along one of their large sides by a gusset adapted to form the sole and along their small sides by lines of join, also joining the opposite faces of said gusset. The invention is more particularly applicable to the manufacture of disposable overshoes.

  • Patent number: 4271610
    Abstract: A pivot plate for attachment to the sole of a shoe comprises paired cylindrical discs which are rotatably fastened to one another in vertical adjacency, and which have antifriction pads located on their inwardly facing surfaces so that said discs rotate freely relative to one another even when subjected to an axial load. A double-backed membrane having a protective cover on one of its sides is attached to the outer surface of one of the discs so that the pivot can be attached to an existing shoe quickly and easily merely by removing the cover and pressing it in place.

  • Patent number: 4271609
    Abstract: An improved snowshoe includes a rigid soleplate swingably mounted for pivotal motion about the forward edge of a rigid cross member extending transversely across and adjustably affixed to the peripheral frame of the snowshoe. A strap binding assembly is mounted to the upper surface of the soleplate to secure a wearer's boot to the soleplate. A spring assembly resiliently retains the soleplate and urges it forwardly about the forward edge of the cross member to augment the conventional action of the snowshoe in lifting the leading edge of the snowshoe upwardly with each step to thereby avoid catching of the leading edge in loose snow.

  • Patent number: 4269082
    Abstract: A device for displacing the walking beam of deep-well pump drives. The walking beam support of the pivot bearing has on its long sides guides for the walking beam, while its narrow sides have slide arrangements for slightly raising and supporting the walking beam during lengthwise displacement. A two-way shifting device is hinged to the pivot bearing. The other end of the shifting device is connected to that part of the walking beam which engages the crank. On both long sides of the walking beam support, a guide rail may protrude beyond the contact plane of the walking beam support and enclose the lower part of the walking beam. The narrow sides of the walking beam support may mount rollers whose axes run parallel to the narrow sides of the walking beam support. The bottom side of the walking beam has arc-shaped recesses for receiving the roller parts protruding beyond the contact area of the walking beam support. The center axes of these recesses are parallel to the rotary axes of the rollers.

  • Patent number: 4267650
    Abstract: Athletic shoes with removable outsoles are disclosed. Each upper is designed to fit an individual foot and ankle of a particular wearer and such upper is provided with an insole securely and permanently connected therewith. Each insole terminates along its peripheral margin with one part of a bead-and-recess mechanically detachable locking member. A removable outsole is provided with a surface contacting tread which is selected to not only best match the surface of a particular sports area but also the condition of such surface at a particular time of use. A flexible member is permanently connected with the outsole and terminates along its peripheral margin with the other part of the mechanical locking member. The outsole and the insole are further connected together by mating Velcro members, tongues and grooves carried by the outsole and insole in paired relations, and other interlocking means.

  • Patent number: 4267714
    Abstract: A hydraulic device for producing a to-and-fro movement of a lever connected to a double-acting piston/cylinder unit comprises a pressure fluid distributor including a control piston for alternately feeding pressure fluid to one or the other side of the piston in the unit to move the lever alternately in opposite directions. A hydraulically actuatable control device for controlling the distributor includes a reciprocable piston member movable in a cylinder and a motion transmitting member in contact with the control piston of the distributor to transmit motion thereto. The piston member has a central large diameter section between two reduced diameter sections and the motion transmitting member is in contact with the surface of the piston member so as to reciprocate transversely in the cylinder when the piston member moves relative to the motion transmitting member between two end positions.

  • Patent number: 4266311
    Abstract: A shoe lasting machine having a receiving device for a last, a heel band for holding a shoe upper on the last, a first wiper for shearing a heel portion of the shoe upper, a second wiper for wiping a side portion of the shoe upper, and a pincer disposed between the first and second wiper for gripping an edge portion of the upper, wherein the pincer moves over the last in a direction away from the last so that a pull directed away from the last is exerted on the edge portion to avoid forming a pocket in the upper. The pincer includes a pincer part articulated on a pincer base body for gripping the edge portion, wherein the pulling force for each individual pincher part and pincer base body is adjustable. The time point of the pincer opening is adjustable with respect to the movement of the wipers and the heel band. Preferably, the receiving device is arranged to receive the last in an upward-directed position, whereby the pincer is moved upwardly away from the last.

  • Patent number: 4261114
    Abstract: A ski boot is provided including a lower sole portion and an upper boot portion supported from and secured to the lower sole portion. The upper boot portion is constructed of stiff material, but includes transverse corrugations extending forwardly and upwardly along opposite sides of the upper and across the instep portion thereof. The corrugations enable forward flexing of the upper portion of the upper boot portion as required to enable a skier to bend his knees and to lean forwardly, and the sole portion is substantially rigid, except in the portion thereof underlying the area of the boot in which the ball of the associated foot is to be received. This portion of the sole is flexible to enable localized flexing of the sole when walking and an attachment is provided therefor operable to selectively render the entire sole substantially inflexible, the attachment being worn while skiing.
