Abstract
Abstract A dispensing device in the form of a closed box-shaped housing consisting of upper and lower housing members defining a dispensing slot. A freely floating annular friction body is guidedly retained within the housing and engages internal slide surfaces on the upper housing member and the two uppermost memo sheets of a stack of memo sheets inserted into the lower housing member. When withdrawing a memo sheet projecting partly through the dispensing slot, this movement will result in a rotational movement of the annular body within the housing whereby the memo sheet underlying the partly projecting memo sheet will be advanced into the dispensing slot.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
284 words
A dispensing device for dispensing memo sheets or the like, comprising of a two-part housing of a lower housing member and an Upper housing member defining together a dispensing slot at a front end of the housing, a stack of sheets adapted to be inserted into said housing, and an endless conveyor means adapted to act upon a stack of memo sheets inserted into said housing, said dispensing device characterized by an annular body floating freely within the interior cavity of said housing, said housing being closed on all sides except for said front end dispensing slot, said annular body engaging with an upper portion the inner surface of the upper housing member top wall, and engaging with a lower portion an uppermost sheet of a stack of memo sheets inserted into said lower housing member, said annular body consisting of a continuous strip of spring steel coated at its outer periphery with a central ribbon-like friction-increasing coating, and adapted to assume a substantially elliptic configuration with substantially arcuate engagement surface portions, in automatically adjusting itself to the spacing between the uppermost memo sheet and the inner surface of said top wall upper housing member, in thereby maintaining an approximately even contact pressure, said annular body furthermore being guided by a mounting provided within said housing cavity, and being in engagement with a pair of profiled bar-type slide surfaces integral with the inner surface of said upper housing member top wall, each of said guide surfaces being extended, at the end facing the dispensing slot, by a vertical stop extending transversely of the longitudinal axis of said annular body to a point located below a horizontal plane through the center of said annular body.
Claim 2
Dependent Claim
284 words
A dispensing device for dispensing memo sheets or the like, comprising of a two-part housing of a lower housing member and an Upper housing member defining together a dispensing slot at a front end of the housing, a stack of sheets adapted to be inserted into said housing, and an endless conveyor means adapted to act upon a stack of memo sheets inserted into said housing, said dispensing device characterized by an annular body floating freely within the interior cavity of said housing, said housing being closed on all sides except for said front end dispensing slot, said annular body engaging with an upper portion the inner surface of the upper housing member top wall, and engaging with a lower portion an uppermost sheet of a stack of memo sheets inserted into said lower housing member, said annular body consisting of a continuous strip of spring steel coated at its outer periphery with a central ribbon-like friction-increasing coating, and adapted to assume a substantially elliptic configuration with substantially arcuate engagement surface portions, in automatically adjusting itself to the spacing between the uppermost memo sheet and the inner surface of said top wall upper housing member, in thereby maintaining an approximately even contact pressure, said annular body furthermore being guided by a mounting provided within said housing cavity, and being in engagement with a pair of profiled bar-type slide surfaces integral with the inner surface of said upper housing member top wall, each of said guide surfaces being extended, at the end facing the dispensing slot, by a vertical stop extending transversely of the longitudinal axis of said annular body to a point located below a horizontal plane through the center of said annular body.
Claim 3
Dependent Claim
57 words
A dispensing device as defined in claim 1, characterized in that a sheet stripping ledge with a portion transversely of the longitudinal axis of said annular body and disposed internally of said internal cavity defined by said housing is formed adjacent the lower edge of the dispensing slot on the inner surface of the lower housing member.
Claim 4
Dependent Claim
38 words
A dispensing device as defined in claim 2, characterized in that the wall portions adjacent the dispensing slot of the substantially vertical outer walls of said upper and lower housing members are conically tapered toward the dispensing slot.
Claim 5
Dependent Claim
91 words
A dispensing device as defined in claim 1, characterized in that to separate individually withdrawn sheets a housing wall portion of the lower housing member adjacent the lower edge of the dispensing slot is of an arcuate configuration, and that the dispensing slot comprises a downwardly flaring conical portion extending from one housing side wall, the lower edge of the conical portion extended by an inclined stepped portion, the inclined stepped portion being extended by a longer substantially horizontal edge portion, all of these portions defining together a wider dispensing section.
Claim 6
Dependent Claim
26 words
A dispensing device as defined in claim 1, characterized in that said coating on the outer periphery of said annular body consists of a rubber tape.
Claim 7
Dependent Claim
43 words
A dispensing device as defined in claim 1, characterized in that said annular body in unbiased condition is of a substantially circular configuration and of a diameter selected in accordance with the feed path length of individual memo sheets toward the dispensing slot.
Claim 8
Dependent Claim
119 words
A dispensing device as defined in claim 1, characterized in that said mounting for said annular body comprises a bracket integral with the inner surface of the upper housing member of said housing, said bracket having a pair of legs and a web portion interconnecting said legs, said web portion being spaced from said upper housing member and defining therebetween an interstice for guidance of said annular body, and a pair of mutually spaced bars extending along the inner top wall surface of the upper housing member in the longitudinal direction of said annular body, said bars defining bearing surfaces for said annular body, the spacing between said bars being somewhat smaller than the width of said annular body.
Claim 9
Dependent Claim
41 words
A dispensing device as defined in claim 1, characteriZed in that a pair of laterally spaced abutment cams adapted to delimit the height of a stack of memo sheets are arranged at the inner surface of the vertical housing rear wall.
