Abstract
Abstract A quenching apparatus that comprises a support circumferentially and spacedly disposed relative to an object to be quenched, with a relatively closely spaced array of jet structures to which cooling fluid is supplied being slidably mounted on the support. Anti-friction means on each of the jet structures are biased into contact with the object for adjustably moving the corresponding jet structures on the support to maintain a selected clearance relative to the object. The jet structures may be selectively adjusted relative to each other to accommodate different sized objects to be quenched. The individual jet structures consisting of a jet opening and a fluid directing spoon are disposed at a relatively small angle to the adjacent surface of the object. An axial series of supports, each provided with an array of jet structures, has the angle of direction of the jet increasingly inclined to the surface of the object going from the entrance support to the exit support.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
Quenching apparatus comprising a support circumferentially and spacedly disposed relative to an object to be quenched, a relatively closely spaced array of jet structures slidably mounted on said support, means for moving each of said jet structures to a selected position on said support relative to the object, and means for supplying a cooling fluid to each of said jet structures, each of said jet structures including antifrictional means for contacting the object, said anti-frictional means being disposed on saiD jet structures so as to space said jet structures predetermined distances from the respectively adjacent surfaces of the object.
Claim 2
Dependent Claim
99 words
Quenching apparatus comprising a support circumferentially and spacedly disposed relative to an object to be quenched, a relatively closely spaced array of jet structures slidably mounted on said support, means for moving each of said jet structures to a selected position on said support relative to the object, and means for supplying a cooling fluid to each of said jet structures, each of said jet structures including antifrictional means for contacting the object, said anti-frictional means being disposed on saiD jet structures so as to space said jet structures predetermined distances from the respectively adjacent surfaces of the object.
Claim 3
Dependent Claim
115 words
Quenching apparatus comprising a support circumferentially and spacedly disposed relative to an object to be quenched, a relatively closely spaced array of jet structures slidably mounted on said support, means for moving each of said jet structures to a selected position on said support relative to the object, and means for supplying a cooling fluid to each of said jet structures, each of said jet structures including a first slide component slidably mounted on a second slide component, means for slidably and adjustably mounting said second slide component on said support, and biasing means on one of said components for urging the said first slide component of said jet structure into contact with the object.
Claim 4
Dependent Claim
115 words
Quenching apparatus comprising a support circumferentially and spacedly disposed relative to an object to be quenched, a relatively closely spaced array of jet structures slidably mounted on said support, means for moving each of said jet structures to a selected position on said support relative to the object, and means for supplying a cooling fluid to each of said jet structures, each of said jet structures including a first slide component slidably mounted on a second slide component, means for slidably and adjustably mounting said second slide component on said support, and biasing means on one of said components for urging the said first slide component of said jet structure into contact with the object.
Claim 5
Dependent Claim
26 words
The combination according to claim 1 wherein biasing means are coupled to each of said jet structures for urging said jet structures individually towards the object.
Claim 6
Dependent Claim
35 words
The combination according to claim 1 wherein said moving means are selectively operative to so adjust the relative positions of said jet structures on said support as to accommodate objects having different cross sectional configurations.
Claim 7
Dependent Claim
45 words
The combination according to claim 1 wherein each of said jet structures includes a jet opening and a fluid directing spoon member disposed adjacent said jet opening, said spoon members being shaped so as to form a cooperatively continuous fluid curtain circumferentially surrounding the object.
Claim 8
Dependent Claim
51 words
The combination according to claim 5 wherein at least a portion of each of said spoon members is disposed at a relatively small angle to the adjacent surface of the object to prevent back flow of cooling fluid therealong in a direction opposite to the direction of movement of the object.
Claim 9
Dependent Claim
43 words
The combination according to claim 1 wherein said supplying means include a ring header mounted adjacent said support and circumferentially surrounding the object, and a plurality of flexible conduits coupled individually to said header and to a corresponding one of said jet structures.
Claim 10
Dependent Claim
50 words
The combination according to claim 1 wherein a plurality of said supports are disposed in axially spaced relation, each of said supports having thereon a similar array of said jet structures, said arrays providing a quenching tunnel through which the object to be quenched moves for successive quenching sprays thereby.
Claim 11
Dependent Claim
27 words
The combination according to claim 8 wherein the jet structures on one of said supports are circumferentially displaced relative to the jet structures on an adjacent support.
Claim 12
Dependent Claim
46 words
The combination according to claim 8 wherein the jet structures on adjacent ones of said supports are so oriented s to direct cooling fluid at different angles to the surface of the object, the angle of direction increasing from the entry support to the exit support.
