Abstract
Abstract A novel transmission band for an automatic transmission and a novel method of installing the same. Automatic transmissions in modern automobiles include a transmission case in which mechanism is so highly compacted as to make replacement of bands a timeconsuming, complicated operation, since the transmission must be removed from the drive train and largely disassembled in order to replace bands. My invention provides a replacement band that may be installed around its drum while the transmission remains connected as part of the drive train. The improved band has an anchoring clip at one end which is attached to the band after the latter is disposed around its drum and therefore the band may be installed by snaking it lengthwise through the limited space between the drum periphery and an adjoining inner surface of the transmission case.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
252 words
A band construction for an automatic transmission, comprising: a circular steel band provided with a brake lining on its inner surface, said band being of the slit type to provide two adjoining free ends, an anchor portion, comprising a body conforming to the curvature of said steel band and overlying the outer surface of the latter at one of said free eNds, and fixed thereto, said body having a front portion extending crosswise of and projecting beyond the said one free end, said front portion being radially and outwardly off-set with respect to the remainder of said body, said body having an opening therethrough, formed by lancing and then displacing radially outwardly a central part of said body to form a rigid tongue and to define a rear edge of said front portion, said tongue and said front portion being outwardly off-set substantially the same amount from said body, the free lip of said tongue being spaced from and parallel to said rear edge of said front portion, a clip attachable to said anchor portion, including a body slightly less in width than the opening in said anchor portion body, and having a head at its forward end, said head having a cross-slot, the body of said clip being projectable into the opening in said anchor portion body to be disposed between said tongue and the outer adjacent surface of said steel band, the marginal portion defining the rear edge of said front portion being seated within said cross-slot in said head.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
86 words
The construction according to claim 1 wherein the body of said clip is projected at an angle through the space between said tongue free lip and said rear edge of said front portion to enter the opening in said anchor portion body, and after said clip body is disposed between said tongue and the outer surface of said steel band said clip body is forced from angular disposition to a position wherein the rear edge of said front portion snaps into the cross-slot in said head.
Claim 4
Dependent Claim
43 words
The construction according to claim 2 wherein said one free end of said steel band has a pair of longitudinal lancings to provide a spring tongue therebetween, said spring tongue being displaced radially inwardly during assembly of said clip with said anchor portion.
