Abstract
Abstract An improved trolley hanger structure for a track conveyor system comprising a sheave, adapted to ride on the exterior of a tubular rail, rotatably mounted on an axle immovably fixed to a vertically open box frame and semi-journalled therethrough at one end to a depending vertical shank supporting a clothes hanger rack or like structure, and at the other end through a novel spring clip retaining the axle end on the box frame. In another embodiment, a pair of sheaves are supported via two novel spring clips to a similar box frame. The novel clip or clips serve only a retaining function since the weight of suspension of the conveyor system is directed vertically upwardly, through the sheave and axle ends, against the box frame.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
95 words
A conveyor hanger comprising a frame having a depending load carrying portion, a non-rotatable transverse axle on said frame, means defining downwardly open socket means in the frame for removably mounting the axle, a sheave rotatably mounted on the axle and adapted to roll along a fixed supporting rail, and readily releasable spring clip means suspended from the frame and connected for retaining the axle in the socket means, the load forces on the hanger being transmitted positively from the depending load carrying portion through the frame, axle and sheave, independently of said clip means.
Claim 2
Dependent Claim
95 words
A conveyor hanger comprising a frame having a depending load carrying portion, a non-rotatable transverse axle on said frame, means defining downwardly open socket means in the frame for removably mounting the axle, a sheave rotatably mounted on the axle and adapted to roll along a fixed supporting rail, and readily releasable spring clip means suspended from the frame and connected for retaining the axle in the socket means, the load forces on the hanger being transmitted positively from the depending load carrying portion through the frame, axle and sheave, independently of said clip means.
Claim 3
Dependent Claim
40 words
The conveyor hanger recited in claim 1, wherein said spring clip means comprises at least one generally V-shaped integral strip of spring metal having hook formations at the ends of diverging legs by which it is suspended from said frame.
Claim 4
Dependent Claim
49 words
The conveyor hanger defined in claim 1, wherein the axle end carries a non-circular formation, and said spring clip means comprises a substantially V-shaped strip shaped at its apex to substantially conform to said formation and having upwardly diverging legs hooked at their ends for attachment to said frame.
Claim 5
Dependent Claim
79 words
The invention as recited in claim 1, wherein said axle includes a pair of bearing supports rotatably mounting said sheave on said axle and retained on said axle by a pair of nut means threaded onto said axle, and said releasable clip means comprises a V-shaped narrow flat strip with free ends hooked for engaging said frame, and the apex of the V-shaped strip extending conformably beneath and partly around at least one of said pair of nut means.
Claim 6
Dependent Claim
55 words
The invention as recited in claim 4, wherein said V-shaped flat strip has a pair of elongate arm portions, each being mesially twisted approximately 90* to provide said apex of the V-shaped flat strip with a broad surface for interengagement with a portion of the periphery of said one of said pair of nut means.
Claim 7
Dependent Claim
68 words
A conveyor hanger as defined in claim 1, wherein there are two parallel non-rotatable axles mounted on said frame which is formed with corresponding downwardly open socket means for receiving the axle ends, support members fixedly connected between the adjacent axle ends, and said spring clip means comprising separate spring clips suspended from the frame to non-rotatably engage the supports to hold said axles in said socket means.
Claim 8
Dependent Claim
114 words
For use in a conveyor system including a generally elongate track and a suspended rack structure, hanger means suspending the rack from the track comprising: a. at least one sheave, rotatable along and on top of the track; b. at least one non-rotatable sheave axle, said sheave being freely rotatably mounted thereon; c. frame means having downwardly open axle reception means at the lower part thereof; d. spring clip means suspended from the frame means and means connecting the lower part of said spring clip means to non-rotatably retain at least one axle end in said aXle reception means; and e. a generally vertically disposed shank interconnecting said frame means and said suspended rack.
Claim 9
Dependent Claim
114 words
For use in a conveyor system including a generally elongate track and a suspended rack structure, hanger means suspending the rack from the track comprising: a. at least one sheave, rotatable along and on top of the track; b. at least one non-rotatable sheave axle, said sheave being freely rotatably mounted thereon; c. frame means having downwardly open axle reception means at the lower part thereof; d. spring clip means suspended from the frame means and means connecting the lower part of said spring clip means to non-rotatably retain at least one axle end in said aXle reception means; and e. a generally vertically disposed shank interconnecting said frame means and said suspended rack.
Claim 10
Dependent Claim
39 words
The invention as recited in claim 7, wherein said shank is fixed on said frame and further includes means defining an axle end reception well receiving an axle end opposite the axle end retained by said spring clip means.
Claim 11
Dependent Claim
69 words
The invention as recited in claim 7, wherein said shank comprises an elongate stem, mesially bent so that its distal portions are vertically offset, one distal portion secured to said frame, the other distal portion being attached to said rack at a rack suspension point arranged vertically beneath a plane drawn through the center of said sheave at generally right angles to the axis of rotation of said sheave.
Claim 12
Dependent Claim
104 words
The invention as recited in claim 7, wherein said hanger means comprises a pair of sheaves, a pair of sheave axles, one for each sheave, and two pairs of opposed axle reception means in said frame, one pair for each axle, said shank including a horizontally disposed hook end rotatably journalled through said frame means, parallel to and vertically above said sheave axles, said spring clip means comprising: a. a pair of sheave axle supports; and b. a pair of spring clips, engaging said sheave axle supports and urging corresponding ends of said pair of axles against said pairs of mating axle reception means.
Claim 13
Dependent Claim
42 words
The invention as recited in claim 10, wherein each of said sheave axle supports includes an upwardly directed notched portion arranged to abut a corresponding annular groove formed in said shank hook end to retain said shank in said open frame means.
Claim 14
Dependent Claim
37 words
The invention as recited in claim 10, wherein each of said sheave axle supports includes a lower shelf, arranged for engagement by one of said spring clip means to retain the sheave support in the frame means.
Claim 15
Dependent Claim
18 words
The invention as recited in claim 12, wherein said shelf further comprises laterally formed spring clip retention means.
Claim 16
Dependent Claim
59 words
The invention as recited in claim 10, wherein each of said spring clip means comprises a generally V-shaped narrow flat strip having arcuated free ends for engaging the upper periphery of said open frame means, the arms of said V-shaped, flat each being mesially twisted to form a broad horizontal base portion which engages a corresponding sheave axle support.
Claim 17
Dependent Claim
54 words
The invention as recited in claim 10, wherein each of said sheave axle supports comprises a central standard portion arranged for face to face contact with a portion of said frame means, and a pair of outer, sheave axle mounting portions vertically planarly spaced from said central standard portion and from said frame means.
