Abstract
Abstract A mounting for an instrument which has to be tilted in the operation of aligning the instrument with an object. The mounting comprising a piston fluid tightly mounted in a housing so as to be axially restrained but rotatable, an instrument support having two legs, the first of which is fixed to the piston and the second of which is rotatably supported on the housing and a releasable clamp means to prevent rotation between the second support leg and the housing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
206 words
A mounting for an instrument or machine which has to be tilted in the operation of aligning the instrument or machine with an object, said mounting comprising a housing, a cylindrical bore in the housing, a cylindrical piston in the housing bore, the piston periphery having working clearance from the bore periphery, a cylindrical extension of the piston concentric with the piston body and projecting beyond the housing, retaining means having a hole therethrough fIxed to the housing with the cylindrical piston body extension passing through the retaining means hole, said retaining means restraining the piston against axial movement but permitting rotary movement thereof, sealing means held in position by the retaining means and sealing the housing to render it liquid tight, means on the housing whereby the housing is mountable on a mounting system; machine support, a first leg on said machine support fixed to the piston extension, a second leg on the support, a stub axle on the housing axially aligned with the piston, a hole in the second leg of the support engaging the stub axle and clamp means to lock the second leg of the support to the stub axle so as to prevent rotary movement of the piston in the housing.
Claim 2
Dependent Claim
206 words
A mounting for an instrument or machine which has to be tilted in the operation of aligning the instrument or machine with an object, said mounting comprising a housing, a cylindrical bore in the housing, a cylindrical piston in the housing bore, the piston periphery having working clearance from the bore periphery, a cylindrical extension of the piston concentric with the piston body and projecting beyond the housing, retaining means having a hole therethrough fIxed to the housing with the cylindrical piston body extension passing through the retaining means hole, said retaining means restraining the piston against axial movement but permitting rotary movement thereof, sealing means held in position by the retaining means and sealing the housing to render it liquid tight, means on the housing whereby the housing is mountable on a mounting system; machine support, a first leg on said machine support fixed to the piston extension, a second leg on the support, a stub axle on the housing axially aligned with the piston, a hole in the second leg of the support engaging the stub axle and clamp means to lock the second leg of the support to the stub axle so as to prevent rotary movement of the piston in the housing.
Claim 3
Dependent Claim
206 words
A mounting for an instrument or machine which has to be tilted in the operation of aligning the instrument or machine with an object, said mounting comprising a housing, a cylindrical bore in the housing, a cylindrical piston in the housing bore, the piston periphery having working clearance from the bore periphery, a cylindrical extension of the piston concentric with the piston body and projecting beyond the housing, retaining means having a hole therethrough fIxed to the housing with the cylindrical piston body extension passing through the retaining means hole, said retaining means restraining the piston against axial movement but permitting rotary movement thereof, sealing means held in position by the retaining means and sealing the housing to render it liquid tight, means on the housing whereby the housing is mountable on a mounting system; machine support, a first leg on said machine support fixed to the piston extension, a second leg on the support, a stub axle on the housing axially aligned with the piston, a hole in the second leg of the support engaging the stub axle and clamp means to lock the second leg of the support to the stub axle so as to prevent rotary movement of the piston in the housing.
Claim 4
Dependent Claim
206 words
A mounting for an instrument or machine which has to be tilted in the operation of aligning the instrument or machine with an object, said mounting comprising a housing, a cylindrical bore in the housing, a cylindrical piston in the housing bore, the piston periphery having working clearance from the bore periphery, a cylindrical extension of the piston concentric with the piston body and projecting beyond the housing, retaining means having a hole therethrough fIxed to the housing with the cylindrical piston body extension passing through the retaining means hole, said retaining means restraining the piston against axial movement but permitting rotary movement thereof, sealing means held in position by the retaining means and sealing the housing to render it liquid tight, means on the housing whereby the housing is mountable on a mounting system; machine support, a first leg on said machine support fixed to the piston extension, a second leg on the support, a stub axle on the housing axially aligned with the piston, a hole in the second leg of the support engaging the stub axle and clamp means to lock the second leg of the support to the stub axle so as to prevent rotary movement of the piston in the housing.
Claim 5
Dependent Claim
54 words
A mounting as claimed in claim 1 wherein said clamp means includes a split through the support second leg extending from the hole therein and a threaded member to draw the portions of the second leg separated by the split together to releasably lock the second leg of the support to the stub axle.
Claim 6
Dependent Claim
37 words
A mounting as claimed in claim 1 wherein said clamp means includes a releasable split clamp assembly fixed to the second leg of the support to lock the second leg of the support to the stub axle.
Claim 7
Dependent Claim
61 words
A mounting as claimed in claim 1 including a releasable connection between the stub axle and the housing whereby the stub axle can be removed from the housing to permit the housing to be installed between the legs of the support after which the stub axle is inserted through the hole in the support second leg and reconnected with the housing.
Claim 8
Dependent Claim
63 words
A mounting as claimed in claim 1 wherein the overall length of the assembled piston and housing in the direction of the piston axis is less than the distance between the support legs, and including a spacer adapted to be clamped between the support first leg and the piston after the stub axle is engaged in the hole in the support second leg.
