Abstract
Abstract The difficult tasks of spreading the bead portions of pneumatic tire casings to mount the casings on rims, insert inner tubes, etc. are facilitated through use of a ringlike inflatable elastomeric diaphragm adapted to forcibly engage the periphery of the tire. Such a diaphragm is more conveniently operated while positioned along a vertical axis. For additional convenience and efficiency, it is desirable to suspend such diaphragm from overhead, for easy movement downwardly to an operating position, and upwardly to a storage position. In order to structurally adapt these diaphragms for vertical suspension, support means are built into or made a structural part of the diaphragm. The support means are preferably a plurality of spaced support loops disposed about the periphery of the diaphragm and anchored within the outer wall thereof.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
81 words
A inflatable, tubular ring of vulcanized elastomeric material used to spread apart pneumatic tire casings comprising A. an inner, radially movable, annular wall for engaging the tread portion of a pneumatic tire casing B. an outer, radially restrained, annular wall, and C. at least three support loops 1. spaced equidistantly along the periphery of said ring, each of said loops a. being anchored to and b. extending from said outer, radially restrained wall whereby said ring may be suspended from overhead.
Claim 2
Dependent Claim
81 words
A inflatable, tubular ring of vulcanized elastomeric material used to spread apart pneumatic tire casings comprising A. an inner, radially movable, annular wall for engaging the tread portion of a pneumatic tire casing B. an outer, radially restrained, annular wall, and C. at least three support loops 1. spaced equidistantly along the periphery of said ring, each of said loops a. being anchored to and b. extending from said outer, radially restrained wall whereby said ring may be suspended from overhead.
