Abstract

Abstract A mold assembly for incorporating a cleat plate in the bottom of a shoe by molding of an outsole of elastomer to the bottom of a lasted upper about a cleat plate to which there are fixed a plurality of cleats comprising an open top mold assembly embodying a sole plate containing holes for receiving the cleats of the cleat plate and holding the latter intermediate the bottom of the mold and the bottom of the lasted upper supported on the mold with predetermined portions of the cleats within the mold cavity and the remainder within the holes in the sole plate, and a method for making such cleated shoe bottoms.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 206 words
THE METHOD OF MAKING A CLEATED BOTTOM COMPRISING PROVIDING CLEATS WITH HEAD OF RELATIVELY LARGE DIAMETER FROM WHICH STEM SHANKS HAVING FIRST CYLINDRICAL PORTIONS NEXT TO THE HEADS, SECOND CYLINDRICAL PORTIONS OF SMALLER DIAMETER EXTENDING FROM THE FIRST CYLINDRICAL PORTIONS, TAPERED PORTIONS EXTENDING FROM THE SECOND CYLINDRICAL PORTIONS, AND FIRST CONICAL SHOULDERS AT THE JUNTIONS OF THE FIRST AND SECOND CYLINDRICAL PORTIONS AND SECOND CONICAL SHOULDERS AT THE JUNCTIONS OF THE SECOND CYLINDRICAL PORTIONS AND THE TAPERED PORTIONS SUPPORTING THE CLAETS BY MEANS OF THE FIRST CONICAL SHOULDERS WITHIN HOLES IN THE BOTTOM OF AN OPEN TOP MOLD CONTAINING A CAVITY OF SMALLER AREA AND DEPTH THAN THE BOTTOM TO BE FORMED, FORMING A CLEAT PLATE OF AN ELASTOMER ABOUT THE PORTIONS OF THE CLEATS ABOUT SAID FIRST SHOULDERS WITHIN SAID MOLD CAVITY, REMOVING THE CLEAT PLATE FROM THE MOLD CAVITY WITH THE CLEATS ATTACHED THERETO, SUPPORTING THE CLEAT PLATE AND THE CLEATS ATTACHED THERETO BY MEANS OF THE SECOND CONICAL SHOULDERS WITHIN HOLES IN THE BOTTOM OF AN OPEN TOP MOLD CONTAINING A CAVITY CORRESPONDING IN AREA AND DEPTH TO THE BOTTOM TO BE FORMED, AND FORMING A BOTTOM OF ELASTOMER ABOUT THE CLEAT PLATE AND THE CLEATS SITUATED WITHIN THE CAVITY ABOVE THE BOTTOM.
Claim 2
Independent Claim 206 words
THE METHOD OF MAKING A CLEATED BOTTOM COMPRISING PROVIDING CLEATS WITH HEAD OF RELATIVELY LARGE DIAMETER FROM WHICH STEM SHANKS HAVING FIRST CYLINDRICAL PORTIONS NEXT TO THE HEADS, SECOND CYLINDRICAL PORTIONS OF SMALLER DIAMETER EXTENDING FROM THE FIRST CYLINDRICAL PORTIONS, TAPERED PORTIONS EXTENDING FROM THE SECOND CYLINDRICAL PORTIONS, AND FIRST CONICAL SHOULDERS AT THE JUNTIONS OF THE FIRST AND SECOND CYLINDRICAL PORTIONS AND SECOND CONICAL SHOULDERS AT THE JUNCTIONS OF THE SECOND CYLINDRICAL PORTIONS AND THE TAPERED PORTIONS SUPPORTING THE CLAETS BY MEANS OF THE FIRST CONICAL SHOULDERS WITHIN HOLES IN THE BOTTOM OF AN OPEN TOP MOLD CONTAINING A CAVITY OF SMALLER AREA AND DEPTH THAN THE BOTTOM TO BE FORMED, FORMING A CLEAT PLATE OF AN ELASTOMER ABOUT THE PORTIONS OF THE CLEATS ABOUT SAID FIRST SHOULDERS WITHIN SAID MOLD CAVITY, REMOVING THE CLEAT PLATE FROM THE MOLD CAVITY WITH THE CLEATS ATTACHED THERETO, SUPPORTING THE CLEAT PLATE AND THE CLEATS ATTACHED THERETO BY MEANS OF THE SECOND CONICAL SHOULDERS WITHIN HOLES IN THE BOTTOM OF AN OPEN TOP MOLD CONTAINING A CAVITY CORRESPONDING IN AREA AND DEPTH TO THE BOTTOM TO BE FORMED, AND FORMING A BOTTOM OF ELASTOMER ABOUT THE CLEAT PLATE AND THE CLEATS SITUATED WITHIN THE CAVITY ABOVE THE BOTTOM.
Claim 3
Dependent Claim 44 words
A method according to claim 1, comprising closing the open top of the mold cavity within which the cleat plate is formed by a cover plate and closing the top of the mold cavity within which the bottom is formed by a lasted upper.
Claim 4
Dependent Claim 22 words
A method according to claim 1, comprising closing the open top of each of the mold cavities with a flat cover plate.
Claim 5
Independent Claim 208 words
The method of making a cleated bottom comprising providing a plurality of cleats, each with a head and shank said shank having at its distal end a tapered portion bored to receive a hardened tip, and intermediate said head and tapered portion axially spaced conical shoulders, the mean diameter of the conical shoulder next to the head being larger than the mean diameter of the conical shoulder farther from the head, supporting a plurality of such cleats in the bottom of an open top mold containing holes in the bottom, the upper ends of which correspond substantially in diameter to the mean diameters of the conical shoulders next to the heads, forming a cleat plate in the cavity about the portions of the cleats in the cavity above the upper ends of the holes in the bottom, removing the cleat plate with cleats attached thereto, mounting the cleat plate with the cleats attached thereto in an opeN top mold cavity containing holes in the bottom corresponding in diameter to the mean diameters of the conical shoulders farther from the heads, and forming a bottom about the cleat plate and the portions of the cleats situated in the cavity above the upper ends of the holes in the bottom.
Claim 6
Independent Claim 208 words
The method of making a cleated bottom comprising providing a plurality of cleats, each with a head and shank said shank having at its distal end a tapered portion bored to receive a hardened tip, and intermediate said head and tapered portion axially spaced conical shoulders, the mean diameter of the conical shoulder next to the head being larger than the mean diameter of the conical shoulder farther from the head, supporting a plurality of such cleats in the bottom of an open top mold containing holes in the bottom, the upper ends of which correspond substantially in diameter to the mean diameters of the conical shoulders next to the heads, forming a cleat plate in the cavity about the portions of the cleats in the cavity above the upper ends of the holes in the bottom, removing the cleat plate with cleats attached thereto, mounting the cleat plate with the cleats attached thereto in an opeN top mold cavity containing holes in the bottom corresponding in diameter to the mean diameters of the conical shoulders farther from the heads, and forming a bottom about the cleat plate and the portions of the cleats situated in the cavity above the upper ends of the holes in the bottom.
Claim 7
Independent Claim 162 words
The method of making a cleated bottom, comprising providing a plurality of cleats, each with a head and shank, said shank having a tapering end portion bored to receive a hardened tip at its terminal end and intermediate the head and tapering end axially spaced conical shoulders, the shoulder next to the head having a larger mean diameter than the shoulder farther from the head, supporting the cleats in holes in the bottom of an open top mold containing holes in the bottom corresponding in diameter to the mean diameters of the conical shoulders farther from the heads, closing the top of the mold cavity with a cover plate, mounting a grid in the cavity between the cover plate and the upper sides of the heads of the cleats to hold the cleats in said holes against displacement and forming a bottom structure of elastomer in the cavity about the portions of the cleats situated therein above the holes in the bottom.
Claim 8
Independent Claim 162 words
The method of making a cleated bottom, comprising providing a plurality of cleats, each with a head and shank, said shank having a tapering end portion bored to receive a hardened tip at its terminal end and intermediate the head and tapering end axially spaced conical shoulders, the shoulder next to the head having a larger mean diameter than the shoulder farther from the head, supporting the cleats in holes in the bottom of an open top mold containing holes in the bottom corresponding in diameter to the mean diameters of the conical shoulders farther from the heads, closing the top of the mold cavity with a cover plate, mounting a grid in the cavity between the cover plate and the upper sides of the heads of the cleats to hold the cleats in said holes against displacement and forming a bottom structure of elastomer in the cavity about the portions of the cleats situated therein above the holes in the bottom.
Claim 9
Dependent Claim 53 words
A method according to claim 5, comprising closing the open top of the mold cavity with a lasted upper and interposing a grid in the cavity between the lower side of the lasted upper and the upper side of the heads of the cleats to hold the cleats in said holes against displacement.
Claim 10
Dependent Claim 23 words
A method according to claim 5, comprising employing as said spacer means a grid comprised of a material compatible with the bottom-forming composition.
Claim 11
Dependent Claim 45 words
A method according to claim 5, comprising employing as said spacer means a grid comprised of a material which will become integrated with the bottom-forming composition during formation of the latter to the configuration of the cavity and the portions of the cleats situated therein.
