Abstract
Abstract An apparatus for wrapping wire on a terminal is provided with a sensing rod extending through the center of the wire attaching tool to detect the proper working relationship of the tool with respect to the terminal. The tool includes an elongated bit element and an inner wrapping sleeve, which rotate to wrap the wire, and an outer stationary sleeve to protect adjacent wrapped terminals. A pneumatic cylinder shifts the sleeves to load the stripped wire in a groove in the bit element and longitudinally extending slots are provided in the sleeves for allowing the stripped end to move into the groove. A motor is provided for rotating the tool to effect the wrapping on the terminal. On the sensing rod, a first end extends into a central bore of the bit element that receives the terminal, and the opposite or second end of the rod responsively operates a spring biased piston, in turn tripping a stationary mounted photo-cell switch. The photocell activates an interlock means in the control circuit to enable the proper operation of the motor, i.e., only when the terminal is properly inserted in the bore.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
83 words
In a wire attaching apparatus for connecting a wire end to a terminal including a wire attaching tool adapted to relatively move with respect to said terminal into working relationship, and means to activate said tool to provide the connection, the improvement comprising sensing means associated with said tool to detect the proper working relationship of said tool with respect to said terminal and means interconnecting said sensing means to said activating means to assure operation only when said tool is properly positioned.
Claim 2
Dependent Claim
83 words
In a wire attaching apparatus for connecting a wire end to a terminal including a wire attaching tool adapted to relatively move with respect to said terminal into working relationship, and means to activate said tool to provide the connection, the improvement comprising sensing means associated with said tool to detect the proper working relationship of said tool with respect to said terminal and means interconnecting said sensing means to said activating means to assure operation only when said tool is properly positioned.
Claim 3
Dependent Claim
40 words
In the wire attaching apparatus of claim 1 wherein said interconnecting means includes interlock means responsive to said sensing means for enabling operation of said activating means only when the proper relationship between said tool and said terminal is provided.
Claim 4
Dependent Claim
80 words
In the wire attaching apparatus of claim 1 wherein said tool is a rotary wrapping tool including an elongated bit element and wrapping sleeve, and said sensing means includes an axially shiftable rod housed in said bit element, a bore in one end of said bit element to receive said terminal, a first end of said rod extending into said bore, and switch means actuated by axial movement of said rod upon engagement of said first end with said terminal.
Claim 5
Dependent Claim
37 words
The apparatus of claim 3 wherein said rod includes a second end extending from the end of said bit element opposite said one end, said switch means being operative in response to movement of said second end.
Claim 6
Dependent Claim
36 words
The apparatus of claim 4 wherein is further included linkage means between said second end and said switch means, spring means to bias said linkage means and said rod in the direction of said first end.
Claim 7
Dependent Claim
66 words
The apparatus of claim 5 wherein is further included a reverse offset extension member on said rod adjacent said second end, a guide block mounted on said bit element, and an offset bore in said block receiving said extension member to prevent relative rotational movement of said rod with respect to said guide block and to limit axial movement of said rod toward said first end.
Claim 8
Dependent Claim
41 words
The apparatus of claim 5 wherein said linkage means includes a piston member abutting said second end, a guide cap slideably enclosing said piston attached to said guide block and an actuator cylinder on the piston to operate said switch means.
Claim 9
Dependent Claim
31 words
The apparatus of claim 7 wherein said switch means includes a photo-cell, means for generating a light beam directed toward said photo-cell, said actuator cylinder serving to break said light beam.
Claim 10
Dependent Claim
29 words
The apparatus of claim 8 wherein said actuator cylinder is sufficiently long to assure tripping of said photo-cell on at least two levels of wire attachment to said terminal.
Claim 11
Dependent Claim
160 words
A wire wrapping apparatus for connecting a wire with a stripped end to a terminal comprising a rotary wire wrapping tool, including an elongated bit element and inner wrapping sleeve on the same, a bore in the end of said bit element for receiving the terminal, means to relatively move said tool and said terminal into working relationship with said terminal inserted in said bore, a stationary outer sleeve, a longitudinally extending groove in said tool and slot in at least said inner sleeve for receiving the stripped end, motor means for rotating at least said inner sleeve to wrap the wire on said terminal, control means for activating said motor means, and sensing means associated with said tool to detect the proper insertion of said terminal in said bore and to responsively operate said control means, whereby operation of said motor means and rotation of said inner sleeve is permitted only when wrapping on said terminal may take place.
Claim 12
Dependent Claim
160 words
A wire wrapping apparatus for connecting a wire with a stripped end to a terminal comprising a rotary wire wrapping tool, including an elongated bit element and inner wrapping sleeve on the same, a bore in the end of said bit element for receiving the terminal, means to relatively move said tool and said terminal into working relationship with said terminal inserted in said bore, a stationary outer sleeve, a longitudinally extending groove in said tool and slot in at least said inner sleeve for receiving the stripped end, motor means for rotating at least said inner sleeve to wrap the wire on said terminal, control means for activating said motor means, and sensing means associated with said tool to detect the proper insertion of said terminal in said bore and to responsively operate said control means, whereby operation of said motor means and rotation of said inner sleeve is permitted only when wrapping on said terminal may take place.
Claim 13
Dependent Claim
34 words
The apparatus of claim 10 wherein said control means includes interlock means responsive to said sensing means for enabling operation of said motor means only when said terminal is properly inserted in said bore.
Claim 14
Dependent Claim
34 words
The apparatus of claim 10 wherein said sensing means includes an axially shiftable rod in said bit element, said bit element including a side loading notch and corresponding elongated notch means in said rod.
Claim 15
Dependent Claim
24 words
The apparatus of claim 12 wherein said notch means is sufficiently long to obviate interference with said wire during the loading and wrapping operations.
