Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
196 words
In wiring harnesses for electrical rotary machines of the type having a housing for supporting fixed coil means, rotary armature means including collector means, fixed brush means for electrical contact with said collector means, and nonmetallic spider means to be mounted in said housing adjacent said brush means, said housing comprising a generally elongated hollow structure having a transverse wall provided with an opening for a field coil lead and bearing means at one end to support one end of the armature means, the other end thereof having closure means to permit insertion of the armature means and said spider means, the brush means including at least one exposed metallic surface, means for positioning said spider means in the housing, said spider means including at least one resilient metallic element for permanent electrical connection with a winding of a field coil means and for resilient electrical contact with said exposed metallic surface of the fixed brush means when positioned in the housing, said spider means also including an eye portion extending in a longitudinal direction disposed in alignment with said opening in the transverse wall for receiving and guiding a field coil lead into said opening.
Claim 2
Dependent Claim
196 words
In wiring harnesses for electrical rotary machines of the type having a housing for supporting fixed coil means, rotary armature means including collector means, fixed brush means for electrical contact with said collector means, and nonmetallic spider means to be mounted in said housing adjacent said brush means, said housing comprising a generally elongated hollow structure having a transverse wall provided with an opening for a field coil lead and bearing means at one end to support one end of the armature means, the other end thereof having closure means to permit insertion of the armature means and said spider means, the brush means including at least one exposed metallic surface, means for positioning said spider means in the housing, said spider means including at least one resilient metallic element for permanent electrical connection with a winding of a field coil means and for resilient electrical contact with said exposed metallic surface of the fixed brush means when positioned in the housing, said spider means also including an eye portion extending in a longitudinal direction disposed in alignment with said opening in the transverse wall for receiving and guiding a field coil lead into said opening.
Claim 3
Dependent Claim
16 words
The invention defined in claim 1, wherein said spider means includes outwardly projecting resilient mounting feet.
Claim 4
Dependent Claim
37 words
The invention defined in claim 1, wherein said fixed coil means includes an inner core assembly, and said spider means includes a surface for complementary engagement with a portion of the core assembly for adhesive attachment thereto.
Claim 5
Dependent Claim
36 words
The invention defined in claim 1, wherein said exposed metallic surface comprises a transversely arranged tubular brush holder, and said resilient metallic element includes a generally U-shaped portion arranged to partially encircle said tubular brush holder.
Claim 6
Dependent Claim
53 words
The invention defined in claim 3, wherein said spider means includes a ring-shaped portion provided with at least two radially outwardly projecting portions for positioning the spider means on said stator core assembly, said ring-shaped portion being provided with a plurality of recesses for attaching said resilient metallic element to the spider means.
Claim 7
Dependent Claim
15 words
The invention defined in claim 1, wherein said eye portion is elongated in cross section.
Claim 8
Dependent Claim
27 words
The inveNtion defined in claim 1, wherein said eye is slit to enable a lead to be inserted therein by deformation of the eye at said slit.
Claim 9
Dependent Claim
36 words
The invention defined in claim 1, wherein said spider means includes a transversely disposed surface, and said eye portion includes a tubular portion projecting from said transverse surface for engagement with said opening in the housing.
Claim 10
Dependent Claim
26 words
