Abstract
Abstract An X-ray goniometer is provided which comprises, a pair of wooden endplates held in a parallel, adjustably spaced relationship by a plurality of connecting dowel rods, a rotatable support mounted to each endplate, each support being rotatable about a common axis perpendicular to the endplates, for supporting each end of the specimen, and means to position the supports in any given angular orientation about the axis. Means may be included to adjust the spacing between endplates and between each support and the axis.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
159 words
A goniometer device for supporting a specimen on an X-ray apparatus during X-ray filming, which comprises: a. first and second upright endplates; b. a plurality of connecting rods and means for connecting said rods at respective ends thereof to said endplates for holding said endplates in a spaced parallel relationship on said X-ray apparatus; c. a first support, rotatably mounted to said first endplate, said first support and first endplate defining a first opening therethrough, for receiving and supporting a first end of said specimen, and a second support, rotatably mounted to said second endplate, said second support and second endplate defining a second opening therethrough, for receiving and supporting a second end of said specimen, said supports being rotatable about a common axis substantially perpendicular to said endplates; and d. a set of reference marks on each said endplate and said rotatable support for gaping the angular position of said supports about said axis relative to said endplates.
Claim 2
Dependent Claim
159 words
A goniometer device for supporting a specimen on an X-ray apparatus during X-ray filming, which comprises: a. first and second upright endplates; b. a plurality of connecting rods and means for connecting said rods at respective ends thereof to said endplates for holding said endplates in a spaced parallel relationship on said X-ray apparatus; c. a first support, rotatably mounted to said first endplate, said first support and first endplate defining a first opening therethrough, for receiving and supporting a first end of said specimen, and a second support, rotatably mounted to said second endplate, said second support and second endplate defining a second opening therethrough, for receiving and supporting a second end of said specimen, said supports being rotatable about a common axis substantially perpendicular to said endplates; and d. a set of reference marks on each said endplate and said rotatable support for gaping the angular position of said supports about said axis relative to said endplates.
Claim 3
Dependent Claim
35 words
The device as recited in claim 1 wherein said connecting rods are substantially rigidly attached to said first endplate and slideably mounted to said second endplate whereby the spacing between said endplates may be adjusted.
Claim 4
Dependent Claim
37 words
The device as recited in claim 2 further comprising means on said second endplate and adjacent said connecting rods for locking said second endplate in a preselected position along said connecting rods relative to said first endplate.
Claim 5
Dependent Claim
29 words
The device as recited in claim 1 further comprising first and second clamping means on, respectively, said first and second supports, for releaseably attaching said specimen to said supports.
Claim 6
Dependent Claim
36 words
The device as recited in claim 4 wherein each of said endplates, connecting rods, connecting means, first and second supports, locking means, and first and second clamping means consist of a material substantially transparent to X-ray.
Claim 7
Dependent Claim
51 words
The device as recited in claim 1 wherein said first and second supports include first and second platforms and further comprises means connected to said platforms for adjustably positioning said platforms along a direction perpendicular to said axis, said supports and positioning means consisting of a material substantially transparent to X-ray.
Claim 8
Dependent Claim
36 words
The device as recited in claim 1 further comprising X-ray transparent means on each of said endplates for releaseably clamping each of said supports in a preselected angular position relative to said endplates about said axis.
