Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
Supports for the rotor of a turbine meter, comprising; a pair of assemblies mounted within the body of the meter, each of the assemblies comprising; a bolt formed with slots extending longitudinally in the bolt and each slot providing an inclined surface, a shaft of bearing material mounted at the end of the bolt and arranged to engage and support the turbine rotor within the body of the meter, a sleeve journalled over the bolt and having an opening at one end for the bearing shaft to extend into engagement with the rotor and openings along its length aligned with the slots and their inclined surfaces in the bolt, and a vane engaged by each inclined surface of the slots in the bolt, the vanes extending from the inclined surfaes through the aligned sleeve openings toward the inner surface of the meter body, whereby the bolt is positioned longitudinally within the sleeve to move the vanes with their iNclined surfaces into engagement with the inner surface of the meter body and stabilize the assembly against longitudinal movement within the meter body.
Claim 2
Dependent Claim
181 words
Supports for the rotor of a turbine meter, comprising; a pair of assemblies mounted within the body of the meter, each of the assemblies comprising; a bolt formed with slots extending longitudinally in the bolt and each slot providing an inclined surface, a shaft of bearing material mounted at the end of the bolt and arranged to engage and support the turbine rotor within the body of the meter, a sleeve journalled over the bolt and having an opening at one end for the bearing shaft to extend into engagement with the rotor and openings along its length aligned with the slots and their inclined surfaces in the bolt, and a vane engaged by each inclined surface of the slots in the bolt, the vanes extending from the inclined surfaes through the aligned sleeve openings toward the inner surface of the meter body, whereby the bolt is positioned longitudinally within the sleeve to move the vanes with their iNclined surfaces into engagement with the inner surface of the meter body and stabilize the assembly against longitudinal movement within the meter body.
Claim 3
Dependent Claim
37 words
The supports of claim 1, wherein; means are provided between the ends of each bolt and its sleeve to adjust and fix their relative longitudinal movements to stabilize the assembly against longitudinal movement within the meter body.
Claim 4
Dependent Claim
47 words
The supports of claim 1, wherein; at least three slots with inclined surfaces are provided for each bolt, at least three aligned openings are provided in each sleeve journalled over each bolt, and at least three vanes are provided between the inclined surfaces and the meter body.
Claim 5
Dependent Claim
172 words
A turbine meter, including; a housing body with a bore supported as a part of a conduit in which fluid is conducted for measurement of its flow, a rotor positioned within the housing body bore to respond to the flowing fluid by rotating on bearing supports, a pair of bearing shafts engaging the rotor to both support the rotor and function as bearings for its rotation, a pinion bolt for each bearing shaft mounting the bearing shaft in the end of the bolt and providing a plurality of inclined surfaces within longitudinally extended slots, a sleeve journalled over each bolt having an opening over each inclined surface of the bolt, and a vane positioned between each inclined surface of the bolt and the wall of the housing body bore, whereby the bolt is positioned longitudinally within the sleeve to move each vane along an inclined bolt surface to bridge between the bolt and the bore wall as a spider support and stabilize the rotor against longitudinal movement within the housing body bore.
