Abstract
Abstract Two bearing shoes, each of which has a wrap angle no greater than 60*, are connected to each other by a thin piece of spring steel to provide a resultant wrap angle of the connected bearing shoes on a spindle of preferably greater than 90*. The piece of spring steel bears against retaining surfaces on the two bearing shoes with the retaining surfaces being parallel to axes of the highest points of the arcs of the spindle contacting surfaces. Because of the flexibility of the spring steel, each of the bearing shoes can rock relative to the other. The bearing shoe, which is first passed by the spindle during its rotation, is fixed to the housing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A bearing shoe construction including: at least two bearing shoes for cooperation with a spindle rotatably mounted in a housing or the like; means to secure said bearing shoes to each other; the total number of said securing means being one less than the total number of said bearing shoes that are secured to each other by said securing means; each of said securing means being separate from any other of said securing means; each of said securing means securing an adjacent pair of said bearing shoes to each other; said securing means securing said bearing shoes to each other with the longitudinal axes of said bearing shoes parallel to each other and to the axis of a spindle with which said bearing shoes cooperate; means to fix at least one of said bearing shoes to a housing in which said bearing shoes are to be mounted; and said securing means permitting each of said bearing shoes to rock relative to any other of said bearing shoes secured thereto and to the spindle with which said bearing shoes cooperate.
Claim 2
Dependent Claim
179 words
A bearing shoe construction including: at least two bearing shoes for cooperation with a spindle rotatably mounted in a housing or the like; means to secure said bearing shoes to each other; the total number of said securing means being one less than the total number of said bearing shoes that are secured to each other by said securing means; each of said securing means being separate from any other of said securing means; each of said securing means securing an adjacent pair of said bearing shoes to each other; said securing means securing said bearing shoes to each other with the longitudinal axes of said bearing shoes parallel to each other and to the axis of a spindle with which said bearing shoes cooperate; means to fix at least one of said bearing shoes to a housing in which said bearing shoes are to be mounted; and said securing means permitting each of said bearing shoes to rock relative to any other of said bearing shoes secured thereto and to the spindle with which said bearing shoes cooperate.
Claim 3
Dependent Claim
35 words
The bearing shoe construction according to claim 1 in which said fixing means fixes at least said bearing shoe that is first passed by the spindle with which said bearing shoes cooperate during its rotation.
Claim 4
Dependent Claim
19 words
The bearing shoe construction according to claim 1 in which said securing means is a flexible sheet of metal.
Claim 5
Dependent Claim
42 words
The bearing shoe construction according to claim 1 in which: each of said bearing shoes has a wrap angle of less than 90*; and said securing means increases the total wrap angle of said adjacent connected bearing shoes to greater than 90*.
Claim 6
Dependent Claim
86 words
The bearing shoe construction according to claim 1 in which: each of said bearing shoes has a surface for contacting the spindle with which said bearing shoes cooperate; each of said bearing shoes has a retaining surface formed therein and parallel to the axis of the spindle contacting surface of each of said bearing shoes at its highest point; and said securing means engages each of said retaining surfaces to position said bearing shoes with the longitudinal axes of said bearing shoes parallel to each other.
Claim 7
Dependent Claim
19 words
The bearing shoe construction according to claim 5 in which said securing means is a flexible Sheet of metal.
Claim 8
Dependent Claim
69 words
The bearing shoe construction according to claim 1 in which: each of said bearing shoes has a surface for contacting the spindle with which said bearing shoes cooperate; each of said bearing shoes has a groove formed therein and parallel to the axis of the spindle-contacting surface of each of said bearing shoes at its highest point; and said securing means has means disposed in each of said grooves.
Claim 9
Dependent Claim
26 words
The bearing shoe construction according to claim 7 in which said securing means is a flexible sheet of metal having opposite ends disposed in said grooves.
