Collimating device for telescopic sights

Claim 2

A collimating element for use in collimating a telescopic sight to a rifle comprising, in combination, a bore supported member having an integral body formed with a uniformly laterally outwardly projecting circular cap at one end thereof, a circular rearwardly and inwardly tapering intermediate portion and a pair of oppositely and outwardly tapering spring members at the opposite end thereof; an upstanding member connected to said bore supported member having an integral body formed with a support portion and a laterally projecting substantially circular base portion provided with a first opening therewithin adapted to accomodate said bore supported member and an upper laterally projecting substantially circular dished portion provided with a second opening therewithin, said dished portion projecting laterally to a greater extent than the lateral projection oF said base portion, film securing means within said dished portion and a film member having sighting indicia thereupon disposed within said dished portion overlying said opening and secured therewithin by said securing means.

Claim 3

A device as described in claim 1 said film securing means comprising a pair of oppositely disposed prong members above and below said second opening.

Claim 4

A device as described in claim 1 said film securing means comprising a pair of V-shaped spaced portions oppositely disposed within said dished portion lateral to said opening therewithin.

Claim 5

A device as described in claim 3 said film also having a pair of mating recesses, each of said recesses adapted to accomodate one of said V-shaped portions.

Claim 6

A device as described in claim 4 each of said V-shaped portions and each of said recesses being of a different size so that the wrong recess cannot be utilized in assembly of the parts.

Claim 7

A device as described in claim 5 said sighting indicia upon said film member being in the form of a grid pattern.

Claim 8

A device as described in claim 6 the sighting indicia upon said film member comprising a series of spaced concentric circles and a set of cross-hairs upon said concentric circles.

Claim 9

A collimiating mechanism adapted to collimate a telescopic sight to a rifle comprising, in combination, a pair of elements, the first of said elements being a light reducing member adapted to fit over the objective lens of a telescopic sight, said light reducing member having a front face provided with an aperture therewithin, a plano-convex lens covering said aperture and said light reducing member also having a substantially circular lateral holding portion; the second of said elements being a sighting member having a portion thereof adapted to fit within the bore of a rifle and an additional portion adapted to extend upwardly from said rifle and in alignment with said light reducing member,said sighting member comprising a bore supported member having an integral body formed with a uniformly laterally and outwardly projecting circular cap member at one end thereof, a circular rearwardly and inwardly tapering intermediate portion and a pair of oppositely and outwardly tapering spring members at the opposite end thereof; an upstanding member connected to said bore supported member having an integral body formed with a support portion and a laterally projecting substantially circular base portion provided with a first opening therewithin adapted to accomodate said bore supported member, and an upper laterally projecting substantially circular dished portion provided with a second opening therewithin, said dished portion projecting laterally to a greater extent than the lateral projection of said base portion, film securing means within said dished portion, and a bearing sighting indicia thereupon disposed within said dished portion and held by said securing means.

Claim 10

A collimiating mechanism adapted to collimate a telescopic sight to a rifle comprising, in combination, a pair of elements, the first of said elements being a light reducing member adapted to fit over the objective lens of a telescopic sight, said light reducing member having a front face provided with an aperture therewithin, a plano-convex lens covering said aperture and said light reducing member also having a substantially circular lateral holding portion; the second of said elements being a sighting member having a portion thereof adapted to fit within the bore of a rifle and an additional portion adapted to extend upwardly from said rifle and in alignment with said light reducing member,said sighting member comprising a bore supported member having an integral body formed with a uniformly laterally and outwardly projecting circular cap member at one end thereof, a circular rearwardly and inwardly tapering intermediate portion and a pair of oppositely and outwardly tapering spring members at the opposite end thereof; an upstanding member connected to said bore supported member having an integral body formed with a support portion and a laterally projecting substantially circular base portion provided with a first opening therewithin adapted to accomodate said bore supported member, and an upper laterally projecting substantially circular dished portion provided with a second opening therewithin, said dished portion projecting laterally to a greater extent than the lateral projection of said base portion, film securing means within said dished portion, and a bearing sighting indicia thereupon disposed within said dished portion and held by said securing means.
