Abstract A device for finely adjusting and fixing a part with respect to a supporting body such as an optical system comprising a plurality of adjusting nuts, each partially formed with a spherical surface and threadably mounted on a respective stud secured to the supporting body with the spherical surface maintained in contact with a stud receiving matching conical recess formed in the surface of the part to be adjusted closest to the supporting body so that the adjusting nuts function as positioning means for the part; a plurality of spacers each formed with a straight edge and also mounted on one of the studs with the straight edge in contact with the remote surface of the part to be adjusted; a plurality of springs mounted on the studs and acting on the spacers to maintain their straight edges in contact with the remote surface of the part; and a plurality of fixing nuts, each threadably engaging one of the studs and formed with a recess for receiving a spring therein so that the fixing nut may be brought into contact with the spacer to exert a clamping force on the part to be adjusted with the spring enclosed entirely in the recess. Modifications of the spacer include forming straight edges on opposite sides thereof disposed at right angles to each other and offsetting the straight edge from the center line of the stud-accomodating opening therein.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
223 words
A device for adjusting and fixing a part requiring fine adjustment with respect to a main body, such as in an optical system, comprising: a. a plurality of studs secured to the main body and each adapted to extend through matching openings formed in the part to be adjusted; b. a plurality of adjusting nuts, each partially formed with a spherical surface and threadably engaging one of said studs on one side of the part to be adjusted with the spherical surface maintained in contact with a conical recess formed in the part to be adjusted so that said adjusting nuts function as positioning means for the part to be adjusted; c. a plurality of spacers, each formed with a straight edge and mounted on one of said studs on the other side of the part to be adjusted with the straight edge in contact with the surface of the part to be adjusted; d. a plurality of springs, each mounted on one of said studs and acting on one of said spacers so that each spacer is maintained in contact with the surface of the part to be adjusted; and e. a plurality of fixing nuts each threadably engaging one of said studs and supporting one end of said springs so as to fix and exert a clamping force on the device.

Independent Claim
223 words
A device for adjusting and fixing a part requiring fine adjustment with respect to a main body, such as in an optical system, comprising: a. a plurality of studs secured to the main body and each adapted to extend through matching openings formed in the part to be adjusted; b. a plurality of adjusting nuts, each partially formed with a spherical surface and threadably engaging one of said studs on one side of the part to be adjusted with the spherical surface maintained in contact with a conical recess formed in the part to be adjusted so that said adjusting nuts function as positioning means for the part to be adjusted; c. a plurality of spacers, each formed with a straight edge and mounted on one of said studs on the other side of the part to be adjusted with the straight edge in contact with the surface of the part to be adjusted; d. a plurality of springs, each mounted on one of said studs and acting on one of said spacers so that each spacer is maintained in contact with the surface of the part to be adjusted; and e. a plurality of fixing nuts each threadably engaging one of said studs and supporting one end of said springs so as to fix and exert a clamping force on the device.
Claim 3
Dependent Claim
50 words
A device according to claim 1 wherein each said fixing nut is formed with a recess for receiving the spring therein whereby said fixing nut may be brought into contact with the spacer to exert a clamping force thereon with the spring being enclosed in said recess in its entirety.
Claim 4
Dependent Claim
50 words
A device according to claim 1 wherein each said spacer is formed on opposite sides with straight edges disposed at right angles to each other, whereby the spacer can be maintained in line contact with the part to be adjusted and with the fixing nut when the latter is tightened.
Claim 5
Dependent Claim
25 words
A device according to claim 1 wherein each said spacer is formed with its straight edge offset from the centerline of the stud-accomodating opening therein.
