Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
213 words
For a materials-handling system employing tracks, trolleys movable along the tracks, and hangers extending from the trolleys for supporting material to be transported, improved combined trolley and hanger apparatus comprising a trolley having a body and rollers rotationally mounted on the body for contacting tracks and for supporting the body on the tracks, said trolley body having first and second spaced body portions wherein the rollers comprise one pair of wheels mounted on first body portion and more than one pair of wheels mounted on the second body portion, a hinge means mounted to the trolley body, and a hanger connected to the hinge, limit means connected respectively to the trolley and to the hanger adjacent the hinge for limiting relative movement between the trolley and the hanger, said limit means comprising segment means mounted on the body near the axle and centered about the axle and further comprising first and second spaced stops mounted on the hanger near the axle, whereby moving the hanger about the axle relative to the trolley body causes the first stop to engage one end of the segment means and moving the hanger about the axle relative to the body in an opposite direction causes the second stop to engage a second end of the segment means.
Claim 2
Dependent Claim
213 words
For a materials-handling system employing tracks, trolleys movable along the tracks, and hangers extending from the trolleys for supporting material to be transported, improved combined trolley and hanger apparatus comprising a trolley having a body and rollers rotationally mounted on the body for contacting tracks and for supporting the body on the tracks, said trolley body having first and second spaced body portions wherein the rollers comprise one pair of wheels mounted on first body portion and more than one pair of wheels mounted on the second body portion, a hinge means mounted to the trolley body, and a hanger connected to the hinge, limit means connected respectively to the trolley and to the hanger adjacent the hinge for limiting relative movement between the trolley and the hanger, said limit means comprising segment means mounted on the body near the axle and centered about the axle and further comprising first and second spaced stops mounted on the hanger near the axle, whereby moving the hanger about the axle relative to the trolley body causes the first stop to engage one end of the segment means and moving the hanger about the axle relative to the body in an opposite direction causes the second stop to engage a second end of the segment means.
Claim 3
Dependent Claim
93 words
The improved combined trolley and hanger apparatus of claim 1, wherein the hanger comprises first and second interconnected vertical shafts, wherein the hinge comprises first and second axles respectively connected between the first body portion and the first shaft and connected between the second body portion and the second shaft, wherein the limit means comprises first and second limit means associated respectively with the first and second body portions and shafts, and wherein spaces between elements of the first limit means are smaller than corresponding spaces between elements of the second limit means.
Claim 4
Dependent Claim
36 words
The improved combined trolley and hanger apparatus of claim 1 wherein a bumper is integrally formed with the hanger and extends beyond the body in a direction transverse to the axle and parallel to the track.
Claim 5
Dependent Claim
54 words
The improved combined trolley and hanger apparatus of claim 1, wherein the body is a relatively flat, vertically oriented body, and further comprising lugs extending outward from upper portions of the body, and guide wheels rotationally mounted on the lugs for engaging walls associated with the tracks for preventing contact of the body therewith.
Claim 6
Dependent Claim
62 words
The improved combined trolley and hanger apparatus of claim 1, wherein the body has spaced openings spaced inward from edges of the body, and further comprising guide axles vertically mounted in the openings and guide rollers mounted on the axles in the openings and extending outward therefrom for engaging vertical edges of the tracks and for preventing contact of the body therewith.
Claim 7
Dependent Claim
112 words
Improved trolley apparatus for use on a walled track comprising: a body, said body means being substantially flat and vertically oriented, lugs mounted on an upper portion of the body and extending outwardly and downwardly therefrom, support rollers rotationally mounted on the body for engaging the track, and for supporting the trolleys on the tracks for movement therealong, a first set of guide wheels rotationally mounted on the lugs for engaging a wall associated with the tracks and for preventing contact of the body and lugs therewith, and a second set of guide wheels mounted on the body for engaging a wall associated with the track preventing contact of the body therewith.
Claim 8
Dependent Claim
112 words
Improved trolley apparatus for use on a walled track comprising: a body, said body means being substantially flat and vertically oriented, lugs mounted on an upper portion of the body and extending outwardly and downwardly therefrom, support rollers rotationally mounted on the body for engaging the track, and for supporting the trolleys on the tracks for movement therealong, a first set of guide wheels rotationally mounted on the lugs for engaging a wall associated with the tracks and for preventing contact of the body and lugs therewith, and a second set of guide wheels mounted on the body for engaging a wall associated with the track preventing contact of the body therewith.
Claim 9
Dependent Claim
25 words
The improved trolley apparatus of claim 6 and wherein the lugs project horizontally and generally perpendicular to the body from upper portions of the body.
Claim 10
Dependent Claim
47 words
Improved trolley apparatus of claim 7, further comprising primary axles mounted horizontally on the body means, and secondary axles generally vertically mounted on the lugs, and whereiN the rollers and first set of guide wheels are mounted respectively on the primary axles and on the secondary axles.
Claim 11
Dependent Claim
40 words
The improved trolley apparatus of claim 8 wherein lugs are oppositely mounted on upper and outward extremities of the body, and wherein secondary axles are downwardly mounted on the lugs and are slightly outwardly inclined with respect to the body.
Claim 12
Dependent Claim
62 words
The improved trolley apparatus of claim 7, wherein the body means defines openings located within the body and spaced from the edges of the body, and wherein said second guide wheels are rotationally mounted within the openings and extending horizontally therefrom beyond the body for engaging a wall associated with the track for preventing contact of the body and the lugs therewith.
Claim 13
Dependent Claim
95 words
Improved trolley apparatus for use with a walled track comprising a generally T-shaped body having openings spaced from each other and spaced inward from the side edges of the vertical member of said T-shaped body, first axles horizontally mounted in the body, support rollers mounted on the first axles for contacting the track, second and third axles with guide wheels mounted thereon for preventing contact of said T-shaped body with the track, said second axles mounted substantially vertically from the horizontal member of said T-shaped body, and said third axles mounted vertically in said openings.
Claim 14
Dependent Claim
95 words
Improved trolley apparatus for use with a walled track comprising a generally T-shaped body having openings spaced from each other and spaced inward from the side edges of the vertical member of said T-shaped body, first axles horizontally mounted in the body, support rollers mounted on the first axles for contacting the track, second and third axles with guide wheels mounted thereon for preventing contact of said T-shaped body with the track, said second axles mounted substantially vertically from the horizontal member of said T-shaped body, and said third axles mounted vertically in said openings.
