Abstract
Abstract Method of making at least two different electrical interconnections with at least two wires extending from windings supported on a dynamoelectric machine core. The method includes moving the core, windings, and at least two wires toward a wire connecting device; orienting and positioning a first one of the at least two wires relative to the device; and thereby conditioning the device to establish a first one of at least two different connection configurations. A first electrical interconnection involving a first wire and having a first connection configuration is formed. A second winding lead then is oriented and positioned relative to the device, thereby to condition the device to form an interconnection having a second connection configuration, and such interconnection is made. A method of scrap removal is provided which includes the steps of exhausting a pneumatic cylinder; guiding the exhausted air to a venturi chamber and thereby establishing a vacuum adjacent a crimping station thereby to collect scrap material; and directing the scrap material, along with the exhausted air, away from the crimping station.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
In apparatus of the type for establishing connections at a connecting station and involving at least one lead wire extending from a stator assembly, and wherein the apparatus includes at least one pneumatic cylinder and also includes connection establishing tooling, the improvement comprising: scrap collection means disposed in the vicinity of the connecting station, said scrap collection means including a confined pathway permitting the flow of fluid therealong and interconnecting the at least one pneumatic cylinder and the scrap collection means; said scrap collection means including a venturi arrangement interconnected with the confined pathway, whereby air exhausted from the at least one pneumatic cylinder is directed into the venturi arrangement and establishes a vacuum in the vicinity of the connecting station that causes debris from the connecting station to be moved into the scrap collection means.
Claim 2
Dependent Claim
136 words
In apparatus of the type for establishing connections at a connecting station and involving at least one lead wire extending from a stator assembly, and wherein the apparatus includes at least one pneumatic cylinder and also includes connection establishing tooling, the improvement comprising: scrap collection means disposed in the vicinity of the connecting station, said scrap collection means including a confined pathway permitting the flow of fluid therealong and interconnecting the at least one pneumatic cylinder and the scrap collection means; said scrap collection means including a venturi arrangement interconnected with the confined pathway, whereby air exhausted from the at least one pneumatic cylinder is directed into the venturi arrangement and establishes a vacuum in the vicinity of the connecting station that causes debris from the connecting station to be moved into the scrap collection means.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 wherein the connection establishing tooling is powered by said at least one pneumatic cylinder.
Claim 4
Dependent Claim
131 words
In apparatus for making crimped connections having a movable toggle linkage movable between first and second positions in response to a pneumatic cylinder, a crimping station, and a crimping tool carried by the toggle linkage, the improvement comprising: a vacuum device positioned in proximity to the crimping station for removing debris therefrom, and air path defining means interconnecting the vacuum device and a region wherein air is confined under elevated pressure; said vacuum device including a venturi, wherein movement of air through the venturi establishes a subatmospheric pressure region in the vicinity of the crimping station, and wherein the exhaust of the pneumatic cylinder is directed to the venturi following a crimping stroke, the exhaust of said cylinder establishing the subatmospheric pressure region and thereby removing debris from the crimping station.
Claim 5
Dependent Claim
131 words
In apparatus for making crimped connections having a movable toggle linkage movable between first and second positions in response to a pneumatic cylinder, a crimping station, and a crimping tool carried by the toggle linkage, the improvement comprising: a vacuum device positioned in proximity to the crimping station for removing debris therefrom, and air path defining means interconnecting the vacuum device and a region wherein air is confined under elevated pressure; said vacuum device including a venturi, wherein movement of air through the venturi establishes a subatmospheric pressure region in the vicinity of the crimping station, and wherein the exhaust of the pneumatic cylinder is directed to the venturi following a crimping stroke, the exhaust of said cylinder establishing the subatmospheric pressure region and thereby removing debris from the crimping station.
Claim 6
Independent Claim
119 words
A method of making a crimped connection and removing debris from a connection making station of a connection making apparatus wherein clips are fed to the station and a mechanism operated by a pneumatic cylinder sequentially folds the clips about lead wires of a stator assembly, the method comprising: advancing a clip to the station; placing at least one wire segment in the clip; pressurizing the pneumatic cylinder to extend the cylinder and secure the clip to the at least one wire segment; retracting the cylinder and expelling exhaust fluid therefrom; and directing the exhaust fluid from the cylinder to a scrap collector to establish a reduced pressure region adjacent the station, thereby to collect debris from the station.
