Abstract
Abstract A pipe for delivering steam under pressure to the longitudinal center of the elongated steam chamber terminates in a discharging nozzle assembly comprising two identical but oppositely positioned nozzles located in a plane parallel to the longitudinal center line of the chamber and discharging in opposite directions respectively. A baffle or divider plate, extending along the axial line in the end of the pipe and at the entrance to the nozzles and extending perpendicular to the plane of the nozzles, equalizes the flow through the nozzles, causing an even circulation throughout the length of the chamber.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
A nozzle assembly for producing an equalized circulation of fluid throughout the interior of an elongated chamber from a delivery pipe leading into the longitudinal center of the chamber and delivering fluid under pressure, said assembly comprising a nozzle head, a connection between the end of the delivery pipe and said nozzle head, a pair of nozzles extending laterally from opposite sides of said head and extending in the same plane, each of said nozzles making a substantially right angle bend and terminating in a discharging mouth having an axis substantially parallel to the longitudinal axis of the chamber, said nozzles being similar but with said mouths discharging in opposite directions respectively, and a divider plate extending along in said delivery pipe end and in said nozzle head dividing said nozzle head equally in half and extending in a plane perpendicular to the plane of said nozzles, whereby to equalize the discharge through said nozzles and the resulting fluid circulation in the respective areas of the chamber.
Claim 2
Dependent Claim
167 words
A nozzle assembly for producing an equalized circulation of fluid throughout the interior of an elongated chamber from a delivery pipe leading into the longitudinal center of the chamber and delivering fluid under pressure, said assembly comprising a nozzle head, a connection between the end of the delivery pipe and said nozzle head, a pair of nozzles extending laterally from opposite sides of said head and extending in the same plane, each of said nozzles making a substantially right angle bend and terminating in a discharging mouth having an axis substantially parallel to the longitudinal axis of the chamber, said nozzles being similar but with said mouths discharging in opposite directions respectively, and a divider plate extending along in said delivery pipe end and in said nozzle head dividing said nozzle head equally in half and extending in a plane perpendicular to the plane of said nozzles, whereby to equalize the discharge through said nozzles and the resulting fluid circulation in the respective areas of the chamber.
Claim 3
Dependent Claim
168 words
The combination of an elongated steam chamber extending transversely over a traveling pulp mat in a paper-making machine and having a horizontal bottom wall with orifices arranged to discharge steam down on the pulp mat, a steam delivery pipe delivering steam under pressure into said chamber, said pipe terminating at the approximate longitudinal center of said chamber, a nozzle assembly connected to the end of said pipe, said assembly consisting of a nozzle head portion and a pair of similar nozzles leading from the sides of said head portion respectively and extending in the same horizontal plane, each of said nozzles terminating in a discharging mouth having its axis substantially parallel to the longitudinal center line of said chamber, said discharging mouths being of equal size but discharging in opposite directions respectively, and a divider plate in said end of said pipe end in said nozzle head, said divider plate extending in a vertical plane and dividing the delivery of steam from said pipe equally between said nozzles.
Claim 4
Dependent Claim
168 words
The combination of an elongated steam chamber extending transversely over a traveling pulp mat in a paper-making machine and having a horizontal bottom wall with orifices arranged to discharge steam down on the pulp mat, a steam delivery pipe delivering steam under pressure into said chamber, said pipe terminating at the approximate longitudinal center of said chamber, a nozzle assembly connected to the end of said pipe, said assembly consisting of a nozzle head portion and a pair of similar nozzles leading from the sides of said head portion respectively and extending in the same horizontal plane, each of said nozzles terminating in a discharging mouth having its axis substantially parallel to the longitudinal center line of said chamber, said discharging mouths being of equal size but discharging in opposite directions respectively, and a divider plate in said end of said pipe end in said nozzle head, said divider plate extending in a vertical plane and dividing the delivery of steam from said pipe equally between said nozzles.
