Abstract
Abstract A multi-angle panel holding device for use on colorimeters comprising a base plate, a rotary turret plate which defines an aperture set in the base plate, and a housing member which encloses a panel holder which is capable of free angular rotation in a vertical and/or horizontal plane relative to the direction of incident light from the colorimeter.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
183 words
The multi-angle panel holding device comprising A. a base plate having a circular aperture B. a rotary turret plate within said base plate, said rotary turret plate being circular and having a beveled edge capable of mating with a similar beveled edge of the base plate thereby allowing for free rotation in a horizontal plane C. a housing mounted on said turret plate, said housing being divided into an upper and lower housing, said upper and lower housing being hingedly fastened to each other, and D. a panel holding means attached to said housing, said panel holding means having attached thereto, means for adjusting and determining angular rotation in a vertical plane and means for locking the panel holding means, said panel holding means being two plates of similar size which are hingedly connected to one another, these two plates being so situated so as to form an upper and a lower plate, said lower plate being a panel holder base plate and having an aperture therethrough, said lower plate pivotally attached to said lower housing, said upper plate being a pressure plate.
Claim 2
Dependent Claim
183 words
The multi-angle panel holding device comprising A. a base plate having a circular aperture B. a rotary turret plate within said base plate, said rotary turret plate being circular and having a beveled edge capable of mating with a similar beveled edge of the base plate thereby allowing for free rotation in a horizontal plane C. a housing mounted on said turret plate, said housing being divided into an upper and lower housing, said upper and lower housing being hingedly fastened to each other, and D. a panel holding means attached to said housing, said panel holding means having attached thereto, means for adjusting and determining angular rotation in a vertical plane and means for locking the panel holding means, said panel holding means being two plates of similar size which are hingedly connected to one another, these two plates being so situated so as to form an upper and a lower plate, said lower plate being a panel holder base plate and having an aperture therethrough, said lower plate pivotally attached to said lower housing, said upper plate being a pressure plate.
Claim 3
Dependent Claim
152 words
The multi-angle panel holding device of claim 1 wherein locking means are attached to the base plate adjacent to the circular aperture to restrict movement of the turret plate, wherein the turret plate is incrementally marked in degrees at its outer edge in order to accurately determine the degree of rotation in a horizontal plane with respect to a fixed point on the base plate, wherein the means for adjusting and determining the amount of rotation in a vertical plane is a semicircular plate incrementally marked in degrees which is perpendicularly mounted on the edge of the panel holder base plate and wherein the means for locking the panel holding means is a notched semicircular plate mounted on said panel holder base plate opposite and parallel to the incrementally marked semicircular plate, said notched semicircular plate capable of mating with a spring loaded lever pivotally mounted on the side of the housing.
Claim 4
Dependent Claim
23 words
The multi-angle panel holding device of claim 2 wherein the panel holder base plate is attached to the lower housing by pivot pins.
Claim 5
Dependent Claim
33 words
The multi-angle panel holding device of claim 3 wherein a plate latch is mounted on the panel holding means pressure plate capable of securing said pressure plate to the panel holder base plate.
Claim 6
Dependent Claim
18 words
The multi-angle panel holding device of claim 1 wherein a panel is contained within the panel holding means.
Claim 7
Dependent Claim
18 words
The multi-angle panel holding device of claim 2 wherein a panel is contained within the panel holding means.
Claim 8
Dependent Claim
18 words
The multi-angle panel holding device of claim 3 wherein a panel is contained within the panel holding means.
Claim 9
Dependent Claim
18 words
The multi-angle panel holding device of claim 4 wherein a panel is contained within the panel holding means.
