Abstract

Abstract An improved mounting head for a tire tool, the mounting head being adapted for either clockwise or counterclockwise rotation (on either an automatic or manual tire changing machine) as desired by the operator. The mounting head is characterized by a forehead that is curved on its leading surface and that extends upward and forward, and a lip that is curved downward and rearward, the forehead and the lip merging together at a mouth. The curvature axis of the lip (which lies parallel to the tool''s x plane) is tranversely disposed relative to the curvature axis of the forehead (which lies in the tool''s Y plane). The forehead and lip are further characterized by being fully symmetrical about the Y plane, the tool''s x and Y planes being at right angles one to the other.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 308 words
A tire tool for a tire changing machine of the type having a rotatable centerpost vertically disposed relative to a tire support table, said tire tool comprising a. a mounting head that includes a forehead that is curved on its leading surface and that extends upward and forward, a lip that is curved downward and rearward, the forehead and the lip merging together at a mouth, and the radius of the forehead''s curvature being about the same as the radius of the lip''s curvature, the leading point on the lip''s inner surface being in a vertical plane, the leading point on said forehead extending at least to said vertical plane, and the innermost point of said mouth being disposed rearwardly of said vertical plane, when viewed from the side and when the tool''s x plane is horizontally disposed, and the curvature axis of the lip lying parallel to the tool''s x plane and the curvature axis of the forehead lying in the tool''s y plane, the curvature axis of the lip being transversely disposed relative to the curvature axis of the forehead, the tool''s x and y planes being at right angles one to the other, and the forehead and lip being fully symmetrical about the y plane, said mounting head thereby being adapted to mount a tire''s bead over a wheel''s rim in either the clockwise or counterclockwise direction as desired by the operator and being adapted to withdrawal from the bead/rim interface when jammed therebetween, b. an elongated body portion integral with said mounting head, said body portion being in the tool''s x plane, and c. slot means formed in said body portion, said slot means being engageable about said centerpost such that said tool''s x axis is disposed at an acute angle relative to said table when said tool is operationally engaged with said centerpost.
Claim 2
Dependent Claim 308 words
A tire tool for a tire changing machine of the type having a rotatable centerpost vertically disposed relative to a tire support table, said tire tool comprising a. a mounting head that includes a forehead that is curved on its leading surface and that extends upward and forward, a lip that is curved downward and rearward, the forehead and the lip merging together at a mouth, and the radius of the forehead''s curvature being about the same as the radius of the lip''s curvature, the leading point on the lip''s inner surface being in a vertical plane, the leading point on said forehead extending at least to said vertical plane, and the innermost point of said mouth being disposed rearwardly of said vertical plane, when viewed from the side and when the tool''s x plane is horizontally disposed, and the curvature axis of the lip lying parallel to the tool''s x plane and the curvature axis of the forehead lying in the tool''s y plane, the curvature axis of the lip being transversely disposed relative to the curvature axis of the forehead, the tool''s x and y planes being at right angles one to the other, and the forehead and lip being fully symmetrical about the y plane, said mounting head thereby being adapted to mount a tire''s bead over a wheel''s rim in either the clockwise or counterclockwise direction as desired by the operator and being adapted to withdrawal from the bead/rim interface when jammed therebetween, b. an elongated body portion integral with said mounting head, said body portion being in the tool''s x plane, and c. slot means formed in said body portion, said slot means being engageable about said centerpost such that said tool''s x axis is disposed at an acute angle relative to said table when said tool is operationally engaged with said centerpost.
Claim 3
Dependent Claim 25 words
An improved mounting head as set forth in claim 1 wherein said mouth defines an included angle of about 115* when viewed from the side.
Claim 4
Dependent Claim 31 words
An improved mounting head as set forth in claim 2 wherein said forehead''s leading edge defines an angle with the tool''s x plane of about 75* when viewed from the side.
Claim 5
Dependent Claim 84 words
An improved mounting head as set forth in claim 1 wherein the width of said forehead is abouT three-fifths the width of said lip as measured at the widest points when viewed from the line of sight transverse to the z plane, and wherein the height of said forehead is about equal to the height of said lip when measured relative to the mouth''s center line and as measured at the highest points when viewed from a line of sight transverse to y plane.
