Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
193 words
A device for displaying merchandise consisting of sheet material convolutely wound to form a roll, said device including a. an upright structure; b. a pair of jointly revolving shaft-support drives in the form of a pair of endless loops supported by said upright structure; c. a pair of shaft-support bearings each affixed to one of said pair of shaft-support drives; d. a horizontal shaft supported by said pair of shaft-support bearings; e. a first transmission gear mounted on one of the ends of said shaft for joint rotation with said one of the ends of said shaft; f. a reversing motor driving a reduction gear driving a second transmission gear; g. a slide member supported by said upright structure and movable substantially horizontally relative to said upright structure, said slide member supporting said reversing motor, said reduction gear and said second transmission gear; and h. means for causing selective engagement and disengagement of said first transmission gear by said second transmission gear to selectively rotate and arrest said first transmission gear and said shaft, said means including operating means for said slide member to move said slide member relative to said upright structure.
Claim 2
Independent Claim
193 words
A device for displaying merchandise consisting of sheet material convolutely wound to form a roll, said device including a. an upright structure; b. a pair of jointly revolving shaft-support drives in the form of a pair of endless loops supported by said upright structure; c. a pair of shaft-support bearings each affixed to one of said pair of shaft-support drives; d. a horizontal shaft supported by said pair of shaft-support bearings; e. a first transmission gear mounted on one of the ends of said shaft for joint rotation with said one of the ends of said shaft; f. a reversing motor driving a reduction gear driving a second transmission gear; g. a slide member supported by said upright structure and movable substantially horizontally relative to said upright structure, said slide member supporting said reversing motor, said reduction gear and said second transmission gear; and h. means for causing selective engagement and disengagement of said first transmission gear by said second transmission gear to selectively rotate and arrest said first transmission gear and said shaft, said means including operating means for said slide member to move said slide member relative to said upright structure.
Claim 3
Dependent Claim
21 words
A device as specified in claim 1 wherein said first transmission gear and said second transmission gear are toothless friction wheels.
Claim 4
Dependent Claim
57 words
A device as specified in claim 1 including spring means biasing said slide member and thereby tending to cause disengagement of said second transmission gear from said first transmission gear, and said operating means for said slide member being affixed to said slide member whereby the bias of said spring means can be overcome by human force.
Claim 5
Dependent Claim
44 words
A device as specified in claim 3 wherein said operating means includes a cable having one end affixed to said slide member, and having another end affixed to an operating lever and being supported by a pulley at a point intermediate the ends thereof.
Claim 6
Dependent Claim
29 words
A device as specified in claim 4 wherein said operating lever is arranged adjacent the lower end of said upright structure, and arranged to be operated by foot action.
Claim 7
Dependent Claim
31 words
A device as specified in claim 1 wherein said upright structure and said slide member are provided with cooperating abutment means establishing a pair of limit positions for said slide member.
Claim 8
Dependent Claim
50 words
A device as specified in claim 1 including a. an electric switch having two limit positions for selectively energizing and deenergizing said reversing motor, and b. coupling means for selectively moving said electric switch to one of said two limit positions thereof depending upon the position of said slide member.
Claim 9
Dependent Claim
50 words
A device as specified in claim 1 wherein said upright structure includes a beam for supporting said slide member, and wherein said beam is slightly inclined, the end thereof adjacent said first transmission gear being arranged at slightly lower level than the end thereof remote from said first transmission gear.
Claim 10
Dependent Claim
53 words
A device as specified in claim 1 wherein said pair of shaft-supporting drives includes a pair of link chains, and wherein at least one of said pair of link chains is covered at a portion of the length thereby by a positioning plate arranged at the side thereof remote from said reversing motor.
