Abstract
Abstract A conveyor trolley hanger of modular construction comprising a proximal hanger member and one or more modular hanger members each removably attachable thereto and to each other by a universal coupling. The hanger members are made of a suitable plastic material, superficially colored or colored throughout to meet government occupational and safety requirements and specifications. The hanger members can be provided with laterally extending arms or members supported upon and by them. Such partssupporting arms are removably attachable to the hanger members. The arms extend laterally from sleeves secured to and upon the hanger members, transversely thereof and disposed in a fixed or a rotatable posture depending upon the construction of the hanger members.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
157 words
A parts-carrying hanger of modular construction for removable attachment to the clevis of a trolley in a trolley conveyor system, said hanger comprising a proximal hanger member having a proximal end portion adapted to be secured to said trolley clevis by a clevis pin, an intermediate rod portion, and a distal end terminating in a first coupling section, one or more modular hanger members each having a proximal end terminating in a complementary second coupling section, an intermediate rod portion, and a distal end terminating in a first coupling section, each modular hanger member being connected to the next preceding hanger member by their complementary coupling sections and by closure means encircling at least portions of said mated coupling sections, and one or more parts-carrying members each having means for attachment to and disposed upon and about each said mated coupling sections, and one or more parts-supporting arms connected to and extending outwardly from said attachment means.
Claim 2
Dependent Claim
157 words
A parts-carrying hanger of modular construction for removable attachment to the clevis of a trolley in a trolley conveyor system, said hanger comprising a proximal hanger member having a proximal end portion adapted to be secured to said trolley clevis by a clevis pin, an intermediate rod portion, and a distal end terminating in a first coupling section, one or more modular hanger members each having a proximal end terminating in a complementary second coupling section, an intermediate rod portion, and a distal end terminating in a first coupling section, each modular hanger member being connected to the next preceding hanger member by their complementary coupling sections and by closure means encircling at least portions of said mated coupling sections, and one or more parts-carrying members each having means for attachment to and disposed upon and about each said mated coupling sections, and one or more parts-supporting arms connected to and extending outwardly from said attachment means.
Claim 3
Dependent Claim

Claim 11
Dependent Claim
32 words
The hanger defined in claim 1, wherein said proximal hanger member rod portion is provided with a transversely projecting flange member to limit the axial travel of a said parts-carrying member thereon.
Claim 12
Dependent Claim
43 words
The hanger defined in claim 1, wherein said modular hanger member Rod portion is provided with a transversely projecting flange member to limit the axial travel of a said parts-carrying member disposed upon and about said mated coupling sections at its proximal end.
Claim 13
Dependent Claim
30 words
The hanger defined in claim 10, wherein said proximal hanger member rod portion is further provided with a spacer sleeve disposed thereon between said parts-carrying member and said flange member.
Claim 14
Dependent Claim
30 words

Claim 16
Dependent Claim
38 words
The hanger defined in Claim 1, wherein said hanger terminates in a distal hanger member comprising a second coupling section and a distal flange member adjacent thereto and extending outwardly therefrom, as a stop for said parts-carrying member.
Claim 17
Dependent Claim
38 words
The hanger defined in claim 1, wherein said hanger terminates in a distal hanger member comprising a first coupling section and a distal flange member adjacent thereto and extending outwardly therefrom, as a stop for said parts-carrying member.
Claim 18
Dependent Claim
39 words
