Abstract
Abstract An elongated rigid support member generally cylindrical in cross-sectional shape and having a pair of clothespin-type clamps mounted thereon with the support member slidingly and rotatably received through the coiled portions of the butterfly springs of the clamps. The jaw ends of the clamps poject outwardly from the same side of the support member and are to perform the funtion of clampingly engaging the pages of an open book to and in position overlying the front and back covers of the book. In addition, one form of the invention invulves an elongated book binding brace projecting outwardly of the same side of the elongated support member from which the jaw ends of the clamps project and underlies the outer surface of the bookbinding in a manner bowing the latter in the area of the open pages of the book thereby rendering the inner marginal edge portions of the open pages more easily readable.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
198 words
A book page holder comprising an elongated support member, a pair of spring closed clamp members projecting and opening outwardly of one side of said support member and adapted to clampingly engage the front and rear covers and adjacent pages of a book therebetween, an elongated bookbinding brace carried by said support member and projecting outwardly of the side thereof outwardly from which said clamp members project, said brace being adapted to be received beweeen the rear cover of an associated book and the adjacent rear page of the book closely adjacent the binding and being provided with a reversely bent outer end portion terminating in a reversely directed end spaced from and generally paralleling the outer end of the brace, said reversely directed end being positionable along the outer surface of the binding of the associated book in order to upwardly deflect the binding between the open pages of the book, said reversely directed end aNd said brace being disposed, generally, in a plane inclined approximately 45* relative to a plane generally paralleling said support member and brace, and said brace being supported from said support member against angular displacement about an axis extending along said brace.
Claim 2
Dependent Claim
198 words
A book page holder comprising an elongated support member, a pair of spring closed clamp members projecting and opening outwardly of one side of said support member and adapted to clampingly engage the front and rear covers and adjacent pages of a book therebetween, an elongated bookbinding brace carried by said support member and projecting outwardly of the side thereof outwardly from which said clamp members project, said brace being adapted to be received beweeen the rear cover of an associated book and the adjacent rear page of the book closely adjacent the binding and being provided with a reversely bent outer end portion terminating in a reversely directed end spaced from and generally paralleling the outer end of the brace, said reversely directed end being positionable along the outer surface of the binding of the associated book in order to upwardly deflect the binding between the open pages of the book, said reversely directed end aNd said brace being disposed, generally, in a plane inclined approximately 45* relative to a plane generally paralleling said support member and brace, and said brace being supported from said support member against angular displacement about an axis extending along said brace.
Claim 3
Dependent Claim
21 words
The combination of claim 1 wherein said clamp members are slidably mounted on said support member for adjustable shifting longitudinally therealong.
Claim 4
Dependent Claim
28 words
The combination of claim 2 wherein said clamp members are rotatably mounted on said support member for adjustable angular positioning about the longitudinal axis of said support member.
Claim 5
Dependent Claim
46 words
The combination of claim 1 wherein said clamp members are slidably mounted on said support member for adjustable shifting longitudinally therealong, the opposite ends of said support member including abutments carried thereby to prevent said clamp members from sliding off the ends of said support member.
Claim 6
Dependent Claim
45 words
The combination of claim 1 wherein said clamp members comprise clothespin-type clamps including corresponding pairs of lever members joined intermediate their opposite ends by means of a butterfly spring including a coiled central portion through which said elongated support member is slidably and rotatably received.
Claim 7
Dependent Claim
18 words
The combination of claim 1 wherein said reversely directed end includes a sleeve frictionally and rotatably mounted thereon.
Claim 8
Dependent Claim
219 words
A book page holder comprising an elongated support member, a pair of spring closed clamp members projecting and opening outwardly of one side of said support member and adapted to clampingly engage the front and rear covers and adjacent pages of a book therebetween, an elongated bookbinding brace carried by said support member and projecting outwardly of the side thereof outwardly from which said clamp members project, said brace being adapted to be received between the rear cover of an associated book and the adjacent rear page of the book closely adjacent the binding and being provided with a reversely bent outer end portion terminating in a reversely directed end spaced from and generally paralleling the outer end of the brace, said reversely directed end being positionable along the outer surface of the binding of the associated book in order to upwardly deflect the binding between the open pages of the book, said reversely directed end including a sleeve frictionally and rotatably mounted thereon, said reversely directed end and the adjacent end of said brace being disposed in a plane inclined generally 45* relative to the plane containing said support member and said brace, said brace being mounted on said support member for slidable adjustment therealong and against angular displacement about its longitudinal axis relative to said support member.
Claim 9
Dependent Claim
219 words
A book page holder comprising an elongated support member, a pair of spring closed clamp members projecting and opening outwardly of one side of said support member and adapted to clampingly engage the front and rear covers and adjacent pages of a book therebetween, an elongated bookbinding brace carried by said support member and projecting outwardly of the side thereof outwardly from which said clamp members project, said brace being adapted to be received between the rear cover of an associated book and the adjacent rear page of the book closely adjacent the binding and being provided with a reversely bent outer end portion terminating in a reversely directed end spaced from and generally paralleling the outer end of the brace, said reversely directed end being positionable along the outer surface of the binding of the associated book in order to upwardly deflect the binding between the open pages of the book, said reversely directed end including a sleeve frictionally and rotatably mounted thereon, said reversely directed end and the adjacent end of said brace being disposed in a plane inclined generally 45* relative to the plane containing said support member and said brace, said brace being mounted on said support member for slidable adjustment therealong and against angular displacement about its longitudinal axis relative to said support member.
Claim 10
Dependent Claim
45 words
The combination of claim 7 wherein said clamp members comprise clothespin-type clamps including corresponding pairs of lever members joined intermediate their opposite ends by means of a butterfly spring including a coiled central portion through which said elongated support member is slidably and rotatably received.
