ABSTRACT:
A jig is provided for use in supporting objects from which fingerprints are to be removed or lifted, the operative mechanism comprising a plurality of pivoted arms which can be made to expand or contract to engage a bottle, glass or the like from the inside or the outside, this movement being effected by means of rotating a junction collar to which the arms are pivoted at their inside end about a central shaft, advancing the collar toward or away from a guide disk. A stand is provided into which the shaft is inserted and in which it may be rotated about its longitudinal axis or removed, and a second shaft having a frustoconical stopper on the end may be used in the stand alternatively to the more complicated, expanding-arm structure described above.
