Abstract
Abstract An adjustable planar mounting apparatus which is free from backlash in the adjusting means and free from mounting plate distortion is disclosed. The mounting plate is oriented spatially by a fixed mounting bolt and two differential screw assemblies. The differential screw assemblies have bellows connectors which permit orientation of the differential screw shaft askew to the plane of the mounting plate and the plane of the support plate without imparting bending moments to the mounting plate.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
228 words
Apparatus for adjusting a planar mounting surface, comprising: a support structure having a conical socket; a mounting plate positioned adjacent to the support structure and having a conical socket; a fixed connecting means joining the mounting plate to the support structure including means for spacing apart the mounting plate from the support structure; a first adjustable connecting means joining the mounting plate to the support structure comprising, a screw shaft penetrating both the support structure and the mounting plate and having a first screw thread at one end of the shaft and a second screw thread at the other end of the shaft, a first nut engaging the first screw thread, the first nut having a spherical surface which cooperates with the conical socket in the support structuRe, a second nut engaging the second screw thread, the second nut having a spherical surface which cooperates with the conical socket in the mounting plate, a first bellows attached to the first nut, the first bellows being fixedly positioned with respect to the support structure, a second bellows attached to the second nut, the second bellows being rotatably positioned with respect to the mounting plate, a spring member concentric with the screw shaft and located between the support structure and the mounting plate, the spring member being in compressed state thereby applying a preload to the first and second nuts.
Claim 2
Dependent Claim
228 words
Apparatus for adjusting a planar mounting surface, comprising: a support structure having a conical socket; a mounting plate positioned adjacent to the support structure and having a conical socket; a fixed connecting means joining the mounting plate to the support structure including means for spacing apart the mounting plate from the support structure; a first adjustable connecting means joining the mounting plate to the support structure comprising, a screw shaft penetrating both the support structure and the mounting plate and having a first screw thread at one end of the shaft and a second screw thread at the other end of the shaft, a first nut engaging the first screw thread, the first nut having a spherical surface which cooperates with the conical socket in the support structuRe, a second nut engaging the second screw thread, the second nut having a spherical surface which cooperates with the conical socket in the mounting plate, a first bellows attached to the first nut, the first bellows being fixedly positioned with respect to the support structure, a second bellows attached to the second nut, the second bellows being rotatably positioned with respect to the mounting plate, a spring member concentric with the screw shaft and located between the support structure and the mounting plate, the spring member being in compressed state thereby applying a preload to the first and second nuts.
Claim 3
Dependent Claim
36 words
The invention according to claim one further including a detachable locking member affixed to the mounting plate, the locking member engaging the second bellows to prevent rotation of the bellows with respect to the mounting plate.
Claim 4
Dependent Claim
24 words
The invention according to claim two wherein the fixed connecting means is joined to the mounting plate by a ball and socket type connector.
Claim 5
Dependent Claim
30 words
The invention according to claim three wherein the fixed connecting means comprises a bolt and an adjusting nut for varying the distance between the mounting plate and the support structure.
Claim 6
Dependent Claim
23 words
The invention according to claim four wherein the means for spacing apart the mounting plate from the support structure is a coil spring.
Claim 7
Dependent Claim
45 words
The invention according to claim one including further: a leaf spring fixedly attached at one end to the support structure and at the other end to the opposing surface of the mounting plate to prevent rotation of the mounting plate about the fixed connecting means.
Claim 8
Dependent Claim
27 words
The invention according to claim one wherein said first screw thread has 40 threads per inch and wherein said second screw thread has 41 threads per inch.
Claim 9
Dependent Claim
23 words
The invention according to claim one wherein said first and second screw threads are both right hand threads or both left hand threads.
Claim 10
Dependent Claim
181 words
The invention according to claim one including further a second adjustable connecting means for joining the mounting plate to the support structure and comprising, a screw shaft penetrating both the support structure and the mounting plate and having a first screw thread at one end of the shaft and a second screw thread at the other end of the shaft, a first nut engaging the first screw thread, the first nut having a spherical surface which cooperates with the support plate conical socket, a second nut engaging the second screw thread, the second nut having a spherical surface which cooperates with the mounting plate conical socket, a first bellows attached to the first nut, the first bellows being fixedly positioned with respect to the support, a second bellows attached to the second nut, the second bellows being rotatably positioned with respect to the mounting plate, a spring member concentric with the screw shaft and located between the support structure and the mounting plate, the spring member being in a compressed state thereby applying a preload to the first and second nuts.
Claim 11
Dependent Claim
43 words

Claim 12
Dependent Claim
70 words
The invention according to claim ten further including: locking means affixed to the mounting plate and engaging each second bellows thereby preventing rotation of the bellows with respect to the mounting plate; and a leaf spring fixedly attached at one end to the support structure and at the other end to the opposing surface of the mounting plate to prevent rotation of the mounting plate about the fixed connecting means.
Claim 13
Dependent Claim
44 words
The invention according to claim eleven wherein said first and second screw threads are both right hand threads or both left hand threads and wherein said first screw thread has 40 threads per inch and said second screw tHread has 41 threads per inch.
