Abstract
Abstract The Assembly comprises a centrally-bored nozzle, a centrally-bored nozzle body, a centrally-bored jet orifice element, and an orifice element-supporting cylinder, the four being in substantially collinear alignment along a longitudinal axis. The cylinder is disposed in the central bore of the body, and it too has a fluid-accommodating passage formed centrally therethrough, as well as a recess in one end in which to nest the orifice element. The cylinder has a straight shank portion which projects into a void in the nozzle body subsisting between the element and the nozzle. Adjustment screws, in penetration of the nozzle body, are arrayed about the shank portion for manipulation to adjust the attitude of the shank portion relative to the longitudinal axis and, thereby, correctively align the element with the nozzle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A fluid-jet-cutting nozzle assembly, comprising: p1 a body; a nozzle; and a jet orifice element; wherein said body, nozzle and element each have a fluid-accommodating passage formed therethrough, and centrally thereof; said body comprises means for (a) receiving said nozzle and element therein, and (b) positioning said nozzle and element therein in a spaced-apart disposition, with said passages in substantially collinear alignment along a given axis; and further including means disposed in said passage in said body for supporting said element in said alignment; and means supported in said body for selectively adjusting the disposition of said element-supporting means to effect, thereby, alteration of the alignment of said element relative to said axis; wherein said body has a land formed therewithin; said element-supporting means has a terminal end thereof in slidable, resting engagement with said land; and said adjusting means comprises means for sluing said terminal end, slidably, about said land.
Claim 2
Dependent Claim
151 words
A fluid-jet-cutting nozzle assembly, comprising: p1 a body; a nozzle; and a jet orifice element; wherein said body, nozzle and element each have a fluid-accommodating passage formed therethrough, and centrally thereof; said body comprises means for (a) receiving said nozzle and element therein, and (b) positioning said nozzle and element therein in a spaced-apart disposition, with said passages in substantially collinear alignment along a given axis; and further including means disposed in said passage in said body for supporting said element in said alignment; and means supported in said body for selectively adjusting the disposition of said element-supporting means to effect, thereby, alteration of the alignment of said element relative to said axis; wherein said body has a land formed therewithin; said element-supporting means has a terminal end thereof in slidable, resting engagement with said land; and said adjusting means comprises means for sluing said terminal end, slidably, about said land.
Claim 3
Dependent Claim
43 words
An assembly, according to claim 1, wherein: said element-supporting means comprises a cylinder; said cylinder has a fluid-accommodating passage formed therethrough, and centrally thereof, and a recess formed in an end thereof; and said element has a portion thereof set in said recess.
Claim 4
Dependent Claim
198 words
A fluid-jet-cutting nozzle assembly, comprising: a body; a nozzle; and a jet orifice element; wherein said body, nozzle and element each have a fluid-accommodating passage formed therethrough, and centrally thereof; said body comprises means for (a) receiving said nozzle and element therein, and (b) positioning said nozzle and element therein in a spaced-apart disposition, with said passages in substantially collinear alignment along a given axis; and further including means disposed in said passage in said body for supporting said element in said alignment; and means supported in said body for selectively adjusting the disposition of said element-supporting means to effect, thereby, alteration of the alignment of said element relative to said axis; wherein said element-supporting means comprises a cylinder; said cylinder has a fluid-accommodating passage formed therethrough, and centrally thereof, and a recess formed in an end thereof; said element has a portion thereof set in said recess; said cylinder has a flat bearing surface, at said end thereof, which rims said recess; said element has a head, with a flat, underlying shoulder, and a straight shank extending from said shoulder; and said shank is set in said recess, and said shoulder is set on said bearing surface.
