Vacuum powered bullet holder system for ballistic analysis

Abstract

It is a major problem encountered in criminology studies, to match the fired bullet with the firearm. One of the acts being featured in the solution of this problem is to provide a holding appropriate for the fired bullet. This invention is about a vacuum powered bullet holder system to be used in forensic analysis of marks on fired bullet.

Claims

1. A bullet holder system to be used in forensic investigations of ballistic marks on a fired bullet, wherein the bullet holder system consists of: a head configured to transfer an air vacuum power to the bullet; a vacuum bushing and a vacuum hole inside of said vacuum bushing, wherein the head is placed inside the vacuum hole and the vacuum hole is fluidly connected to the head; a pneumatic hose connection hermetically sealed to the vacuum bushing and configured to transfer the air vacuum power from an external source; wherein, the vacuum bushing has a plurality of sealing elements to hold the head, which allow a negligible amount of air leakage which does not affect a hold operation; and a roll motor assembly configured to roll the bullet by 360 degrees and a gap for a shaft of the roll motor assembly, wherein the roller motor assembly is disposed in a roller motor housing; wherein, an inner structure of the head transferring the vacuum power to the bullet has a conic shaped shrinking geometry and is coated with a semi soft mould; wherein the bullet has a conical front end located inside the conic shaped shrinking geometry of the head; and wherein the roller motor housing and the vacuum bushing are stationary seated on a base.

DETAILED DESCRIPTION OF THE INVENTION

(8) The invention holds the bullet from the conical front end (201), keeps the bullet still via the air vacuum force supplied to the bullet holder system and lets quick and easy visualization of the ballistic marks (202).

(9) The invention is a bullet holder system, which lets the bullet to be rolled while it is held from the conical front end and kept still via the air vacuum force.

(10) The cross section of the bullet holder system which transfers the vacuum force to the bullet is shown in FIG. 1. The bullet holder system comprising; holder head (101) containing semi soft mould (102), first sealing item and second sealing item (105,106), pneumatic hose connection (104) and the body containing the vacuum hole (103).

(11) In FIG. 2, a non-deformed bullet is shown. The bullet consists of a conical front end (201) and a cylindrical rear part containing representative ballistic marks (202).

(12) Air vacuum power is generated by an external source. A semi-flexible pneumatic hose, which is flexible enough to ease the assembly and hard enough to prevent the bending, is transferring the air vacuum force from the external source to the bullet holder system. The hose is connected to the pneumatic hose connection (fitting) (104) on the bullet holder system. The fitting and the vacuum bushing (108) connection are hermetically sealed. To minimize the air infiltration during the roll movements, vacuum bushing (108) contains first sealing item and second sealing item (105,106). The holder head (101) is placed into the vacuum bushing (108) and it is held by the first sealing item and second sealing item (105,106) in its position. Flexible rubber hermetical elements prevent the decrease in vacuum power while the holder head (101) is rolling. Semi soft material, which is similar to silicon material, is moulded (102) and placed into the holder head (101). A silicon based material as well as any soft solid chemical can be used in the system. The vacuum hole (103) in the vacuum bushing (108) lets the air vacuum power to be transferred up to the semi soft mould (102) placed into the holder head. Bullet's conical front part (201) is placed into conical shaped semi soft mould (102) of the holder head (101) and kept still via the air vacuum power.

(13) This lets the holding of the non-deformed or slightly deformed bullets. If there exists significant amount of deformation, a special mastic, which lets hermetical seal, is applied to the conical front part (201) of the bullet to be able to hold it.

DESCRIPTION OF THE INDUSTRIAL APPLICATION OF THE INVENTION

(14) This invention provides a bullet holder system for the analysis of ballistic marks on the fired bullet. It can be used as a bullet holder system at data acquisition stage necessary for an autonomous computer supported analyse system for fired bullets. Besides, suitable structured samples, to be analysed under sensor of any optical or digital imaging, may be hold and rolled by bullet holder system, so the sample may be analysed or images may be taken from quite a few points.
