Abstract
A Magnetic, latent fingerprint development brush featuring a non-rigid, removable, disposable cover/body, to be used when developing latent fingerprints on contaminated surfaces. The cover can be removed and cleaned or disposed of and exchanged with a new cover. The non-rigid design allows operation without tension springs. The tip is less abrasive against surfaces being printed, since it has no sharp rigid edges. This lessens the chance of distortion of the latent print. The design is simple. A magnetic rod is attached to a handle, which is inserted into a flexible removable cover/body. A light grip holds the cover against the handle during use.
Claims1
A disposable magnetic fingerprint brush for attracting and distributing ferrous fingerprint powder, said brush comprising a magnet/piston assembly and a removable protective cover/shield having a tip, said protective cover/shield constructed of thin flexible plastic and fitted over said magnet/piston assembly, said protective cover/shield adapted to compress inward against said magnet/piston assembly when gripped, said magnet/piston assembly adapted to be engaged in various positions within said protective cover/shield in order to control the amount of ferrous fingerprint powder to be attracted to the tip of said protective cover/shield.
