Abstract
Abstract A carpet roll unloading and transporting assembly is provided comprising an elongated rectangular frame with legs extending downwardly from the corners and terminating in castors. An electrically driven drum is provided at one end of the assembly which winds and unwinds a pair of cable members to raise and lower rolls of carpeting for transporting or cutting off of portions for use. One of the cables is used in the assembly for unloading of rolls of carpeting from a truck.

Claim 1
Independent Claim
299 words
A manually movable carpet roll unloading and transporting assembly capable of handling a variety of carpet roll sizes, comprising: a. a rectangular frame member having a length several times the width thereof and having a plurality of cross bar members between the long sides thereof and intermediate the ends, said cross bar members having means for mounting a pulley therefrom; b. leg members in engagement with and extending substantially vertically downwardly from the corners of said rectangular frame and terminating in castors, said legs defining obstruction-free openings therebetween over the major portion of their length; c. a drum rotatably mounted to said frame member adjacent one end thereof with its axis of rotation transverse to the long sides of said frame; d. pulley means attached to at least one of said cross bar members remote from said drum, said pulley means constructed to releasably engage a cable; e. nylon rope cable mounted to said drum to provide two free ends of cable, the first of said free ends of cable extending downwardly from said drum to at least the base of said legs in the unwound condition to provide a first vertical lifting means at the drum end of said frame, the second of said free ends extending from said drum in a first operative position over said pulley means and downwardly therefrom to thereby provide a second vertical lifting means at a position remote from said drum end and extending directly from said drum between and beyond the legs of the opposite end of said frame so as to provide a means for drawing a carpet from the bed of a vehicle into a position intermediate said leg members; and f. electrical motor means connEcted to said drum for rotating said drum to wind and unwind said cables.

A manually movable carpet roll unloading and transporting assembly capable of handling a variety of carpet roll sizes, comprising: a. a rectangular frame member having a length several times the width thereof and having a plurality of cross bar members between the long sides thereof and intermediate the ends, said cross bar members having means for mounting a pulley therefrom; b. leg members in engagement with and extending substantially vertically downwardly from the corners of said rectangular frame and terminating in castors, said legs defining obstruction-free openings therebetween over the major portion of their length; c. a drum rotatably mounted to said frame member adjacent one end thereof with its axis of rotation transverse to the long sides of said frame; d. pulley means attached to at least one of said cross bar members remote from said drum, said pulley means constructed to releasably engage a cable; e. nylon rope cable mounted to said drum to provide two free ends of cable, the first of said free ends of cable extending downwardly from said drum to at least the base of said legs in the unwound condition to provide a first vertical lifting means at the drum end of said frame, the second of said free ends extending from said drum in a first operative position over said pulley means and downwardly therefrom to thereby provide a second vertical lifting means at a position remote from said drum end and extending directly from said drum between and beyond the legs of the opposite end of said frame so as to provide a means for drawing a carpet from the bed of a vehicle into a position intermediate said leg members; and f. electrical motor means connEcted to said drum for rotating said drum to wind and unwind said cables.
Claim 3
Dependent Claim
29 words
An assembly in accordance with claim 1 wherein said frame member has tubular members extending downwardly at the corners thereof and said leg members adjustably telescope with said tubes.
Claim 4
Dependent Claim
19 words
An assembly in accordance with claim 1 wherein the nylon ropes have permanent loop members at the ends thereof.
Claim 5
Dependent Claim
291 words
A manually movable carpet roll unloading and transporting assembly capable of handling a variety of carpet roll sizes, comprising: a. a frame member having a length several times the width thereof, said frame member including at least one longitudinal support member having means for mounting a pulley member therefrom; b. leg members in engagement with and extending substantially vertically downwardly from the corners of said frame and terminating in castors, said legs defining obstruction-free openings therebetween over the major part of their length; c. a drum rotatably mounted in supportive relation to said frame member near one end thereof, with its axis of rotation transverse to the longitudinal axis of said frame; d. pulley means supported by said longitudinal support member at a point substantially removed from said drum member, said pulley means constructed to releasably engage a cable; e. nylon rope cable mounted to said drum to provide two free ends of cable, the first of said free ends of cable extending downwardly from said drum to at least the base of said legs in the unwound condition to provide a first vertical lifting means at the drum end of said frame, the second of said free ends extending from said drum in a first operative position over said pulley means and downwardly therefrom to thereby provide a second vertical lifting means at a position remote from said drum end and extending directly from said drum between and beyond the legs of the opposite end of said frame so as to provide a means for drawing a carpet from the bed of a vehicle into a position intermediate said leg members; and f. electrical motor means connected to said drum for rotating said drum to wind and unwind said cables.
Claim 6
Dependent Claim
291 words
A manually movable carpet roll unloading and transporting assembly capable of handling a variety of carpet roll sizes, comprising: a. a frame member having a length several times the width thereof, said frame member including at least one longitudinal support member having means for mounting a pulley member therefrom; b. leg members in engagement with and extending substantially vertically downwardly from the corners of said frame and terminating in castors, said legs defining obstruction-free openings therebetween over the major part of their length; c. a drum rotatably mounted in supportive relation to said frame member near one end thereof, with its axis of rotation transverse to the longitudinal axis of said frame; d. pulley means supported by said longitudinal support member at a point substantially removed from said drum member, said pulley means constructed to releasably engage a cable; e. nylon rope cable mounted to said drum to provide two free ends of cable, the first of said free ends of cable extending downwardly from said drum to at least the base of said legs in the unwound condition to provide a first vertical lifting means at the drum end of said frame, the second of said free ends extending from said drum in a first operative position over said pulley means and downwardly therefrom to thereby provide a second vertical lifting means at a position remote from said drum end and extending directly from said drum between and beyond the legs of the opposite end of said frame so as to provide a means for drawing a carpet from the bed of a vehicle into a position intermediate said leg members; and f. electrical motor means connected to said drum for rotating said drum to wind and unwind said cables.
Claim 7
Dependent Claim
28 words
An assembly in accordance with claim 4 wherein said two cables are individually wound upon separate drum members and the drum members may be rotated separately or simultaneously.
