Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
150 words
A one-piece clevis for interconnecting drive links comprising a body having a connector means for securing said clevis to one of the drive links, resilient bearing support arms generally flexible toward each other and extending from said body in spaced apart relation in the normal as-formed condition thereof, a bearing pintle on one of said arms extending axially inwardly from said one arm toward said other arm and terminating in a retaining means between said arms, said bearing pintle being adapted to receive the other drive link thereon in driving relation between said arms, and said other arm having an aperture means for receiving and releasably retaining said pintle by retaining said retaining means therein when said arms are moved together beyond a predetermined spacing distance therebetween, whereby the other drive link received on said pintle will be drivingly born by said pintle in a given space between said arms.
Claim 2
Dependent Claim
150 words
A one-piece clevis for interconnecting drive links comprising a body having a connector means for securing said clevis to one of the drive links, resilient bearing support arms generally flexible toward each other and extending from said body in spaced apart relation in the normal as-formed condition thereof, a bearing pintle on one of said arms extending axially inwardly from said one arm toward said other arm and terminating in a retaining means between said arms, said bearing pintle being adapted to receive the other drive link thereon in driving relation between said arms, and said other arm having an aperture means for receiving and releasably retaining said pintle by retaining said retaining means therein when said arms are moved together beyond a predetermined spacing distance therebetween, whereby the other drive link received on said pintle will be drivingly born by said pintle in a given space between said arms.
Claim 3
Dependent Claim
35 words
A one-piece clevis as defined in claim 1 wherein said arms are normally spaced apart the farthest at the end thereof which is the farthest away from said body in the normal as-formed condition thereof.
Claim 4
Dependent Claim
30 words
A one-piece clevis as defined in claim 1 wherein said support arms extend at acute angles with respect to the axis of said body in the normal as-formed condition thereof.
Claim 5
Dependent Claim
30 words
A one-piece clevis as defined in claim 1 wherein said support arms extend divergently from the outer edges of said body to provide a predetermined space therebetween at said body.
Claim 6
Dependent Claim
49 words
A one-piece clevis as defined in claim 1 wherein said bearing pintle has a connecting drive link bearing portion supported between said pintle retaining means and the arm from which said pintle extends for receiving and positively bearing the other drive link in the driving relation between said arms.
Claim 7
Dependent Claim
69 words
A one-piece clevis as defined in claim 1 wherein said bearing pintle retaining means has a resiliently deformable rounded end portion having a lateral dimension greater than the smallest diameter of said arm aperture for respectively deformably guiding said pintle retaining means into said arm aperture and expandably releasably retaining said pintle retaining means in said arm aperture means when said arms are moved together beyond the predetermined distance.
Claim 8
Dependent Claim
42 words
A one-piece clevis as defined in claim 1 wherein said bearing pintle retaining means and said aperture retaining means have resiliently deformable and interlocking complementing surfaces for releasably retaining said pintle in said aperture by complementally retaining said pintle retaining means therein.
Claim 9
Dependent Claim
50 words
A one-piece clevis as defined in claim 7 wherein said interlocking complementary surfaces respectively comprise axially complemental surfaces having a diminishing taper in a direction away from said pintle arm and axially shorter respectively complemental and resiliently deformable surfaces having a diminishing taper in a direction toward said pintle arm.
Claim 10
Dependent Claim
66 words
A one-piece clevis as defined in claim 6 wherein said bearing pintle retaining means and said aperture retaining means have resiliently interlocking complementing surfaces for releasably retaining said pintle in said aperture, and said interlocking surfaces comprise axially complemental surfaces having a diminishing taper away from said pintle arm and axially shorter respectively complemental and resiliently deformable surfaces having a diminishing taper toward said pintle arm.
Claim 11
Dependent Claim
82 words
A one-piece clevis as defined in claim 1 wherein said bearing pintle retaining means has a rounded end portion having a lateral dimension greater than the smallest diameter of said arm aperture for respectively deformably guiding said pintle retaining means into said arm aperture and expandably releasably retaining said pintle in said arm aperture means with said pintle retaining means in engagement with said aperture arm and positioned within said aperture means with said arms are moved together beyond the predetermined distance.
Claim 12
Dependent Claim
60 words
A one-piece clevis as defined in claim 10 wherein said aperture retaining means aperture is provided with circumferentially spaced radially extending cuts therethrough to provide resilient radially extending fingers whereby said fingers will be resiliently axially deflected to allow passage of said pintle through said aperture and to return upon passage of said pintle end portion to retain said pintle.
Claim 13
Dependent Claim
31 words
A one-piece clevis as defined in claim 11 wherein said pintle has an annular retaining trough adjacent said end portion thereof for axially receiving and retaining said fingers on said pintle.
Claim 14
Dependent Claim
91 words
A one-piece clevis as defined in claim 12 wherein said trough comprises an abruptly tapered inwardly extending shoulder adjacent said pintle end portion and a radially extending shoulder axially spaced therefrom whereby said gradually tapered pintle end will provide entry of said pintle into said retaining aperture as a result of a minimum given force and said abrupt annular trough shoulder will provide withdrawal of said pintle only upon exertion of a much greater force to provide a ready connection and a resistive disconnection between said pintle and said retaining arm.
