Abstract

Abstract Apparatus for preparing fragments from tire casings and the like. The specific apparatus disclosed means revolvably supporting the tire casing for rotation about its axis. Such supporting means also includes opposed squeeze rollers that bear against opposite sidewalls of the tire casing, thus to flatten the tire casing. Cutting means in the apparatus includes a cutter which moves during operation in successive cutting passes across the periphery of the tire casing adjacent where such is confined by said opposed squeeze rollers.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 67 words
Apparatus for preparing fragments from tire casings and the like comprising opposed squeeze members adapted to confine the tire casing by bearing on opposite sides thereof, cutting means for cutting fragments from the periphery of the tire casing adjacent where such casing is confined by the squeeze members, and means for rotating the tire casing about the axis there-of as fragment cutting by said cutter means progresses.
Claim 2
Dependent Claim 67 words
Apparatus for preparing fragments from tire casings and the like comprising opposed squeeze members adapted to confine the tire casing by bearing on opposite sides thereof, cutting means for cutting fragments from the periphery of the tire casing adjacent where such casing is confined by the squeeze members, and means for rotating the tire casing about the axis there-of as fragment cutting by said cutter means progresses.
Claim 3
Dependent Claim 26 words
The apparatus of claim 1, which further includes means for shifting the casing laterally of its axis and towards said cutting means as fragment cutting progresses.
Claim 4
Dependent Claim 44 words
The apparatus of claim 2, wherein the squeeze members comprise opposed roller members adapted to come up against opposite sidewalls of the tire casing, and the means for rotating the tire casing comprises motor means producing powered rotation of at least one roller member.
Claim 5
Dependent Claim 44 words
The apparatus of claim 2, wherein the means for shifting the casing laterally comprises clamp means for clamping onto the bead region of the tire casing, and a mounting for said clamp means accommodating movement laterally of the axis of the casing clamped thereby.
Claim 6
Dependent Claim 87 words
The apparatus of claim 2, wherein the means for shifting the casing laterally comprises clamp mounting structure which in operative position extends into the central void region circumscribed by the usual tire casing, adjustable clamps radiating from said mounting structure adapted to clamp onto the bead region of the tire casing, supporting means supporting the clamp mounting structure for rotation about the axis of the tire casing held by the clamp structure, and means for shifting said supporting means laterally of the axis of the tire casing.
Claim 7
Dependent Claim 112 words
Apparatus for preparing fragments from tire casings and the like comprising clamp means for clamping onto the bead region of the tire casing, said clamp means including clamp mounting structure which in operative position extends into the central void region circumscribed by the usual tire casing, and adjustable clamps radiating from said mounting structure adapted to clamp onto the bead region of the tire casing, cutting means spaced radially from said clamp means, for cutting fragments from the periphery of a tire casing held by the clamp means, and means for relatively adjustably shifting said cutting means and clamp means to decrease the radial spacing between the two as fragment cutting progresses.
Claim 8
Dependent Claim 112 words
Apparatus for preparing fragments from tire casings and the like comprising clamp means for clamping onto the bead region of the tire casing, said clamp means including clamp mounting structure which in operative position extends into the central void region circumscribed by the usual tire casing, and adjustable clamps radiating from said mounting structure adapted to clamp onto the bead region of the tire casing, cutting means spaced radially from said clamp means, for cutting fragments from the periphery of a tire casing held by the clamp means, and means for relatively adjustably shifting said cutting means and clamp means to decrease the radial spacing between the two as fragment cutting progresses.
Claim 9
Dependent Claim 32 words
The apparatus of claim 6 which further comprises means for rotating under power a tire casing held by said clamp means with such rotation being about the axis of the tire casing.
Claim 10
Dependent Claim 40 words
The apparatus of claim 6, wherein said cutting means comprises an anvil and a movable knIfe movable across said anvil, and which further comprises means for confining the tire casing by bearing on opposite sides thereof adjacent said cutting means.
Claim 11
Dependent Claim 61 words
The apparatus of claim 6, wherein said cutting means comprises an anvil and a movable knife movable across said anvil, and which further comprises opposed squeeze members adapted to confine the tire casing by bearing on opposite sides thereof located adjacent said cutting means, said squeeze members by so confining the tire casing substantially flattening the casing adjacent the cutting means.
Claim 12
Dependent Claim 78 words
Apparatus for preparing fragments from a tire casing and the like comprising means revolvably supporting the tire casing for rotation about the axis thereof, cutter means including a cutting device movable in cut-ting passes across the outer periphery of the tire casing held by said first-mentioned means, said first-mentioned means including means for confining the tire casing by bearing on opposite sides thereof adjacent said cutting means whereby the tire casing is reduced to a substantially flattened condition.
Claim 13
Dependent Claim 78 words
Apparatus for preparing fragments from a tire casing and the like comprising means revolvably supporting the tire casing for rotation about the axis thereof, cutter means including a cutting device movable in cut-ting passes across the outer periphery of the tire casing held by said first-mentioned means, said first-mentioned means including means for confining the tire casing by bearing on opposite sides thereof adjacent said cutting means whereby the tire casing is reduced to a substantially flattened condition.
