To aZZ whom it may concern.
Be it known that we, ROBERT BAYLES ARMSTRONG and GEORGE PATERsON, both subjects of the King of the United Kingdom of Great Britain and Ireland, and residing at- Newcastle-upon-Tyne, England, have invented a certainvnew and useful Improvement in Valve Devices, (for which I have filed application in Great Britain June 17, 1918, Patent N 0. 128,373,) of which thefollowing is a specification.
This invention relates to a valve device including two operatively connected valve elements proper engageable with separate seats and controlling separate passages, through one of which passages flows superheated steam andthrough the other of which flows saturated steam, ,whereby to control the proportions of superheated and ot saturated steam to be admitted to steam engines, etc, without interference with the continuity of circulation through the supermain engines for example.
heater elements when maneuvering with the described.
Figs 1 and 2 of the accompanying drawings are vertical sections of valve devices embodying the invention.
Figs. 1 and 2'illustrate constructions each comprising a double beat valve operating in a casing 1 having separate inlets 2 and 3 communicating respectively with a source of superheated steam supply and with a source of saturated steam supply, one beat 4 controlling the passage of superheated steam Specification of Letters Patent.
The device according to the invention Patented Jan. 3, 1922.
Application filed August 21, 1920. Serial No. 405,125.
and the other beat 5 controlling the passage of saturated steam.
To permit maintenance of the balance of such double beat valve, the valve elements 4, 5 are of substantially equal area; inorder, however, to take account of the circumstance that the quantity of superheated steam to be passed may be different from the quantity of saturated steam to be passed, one of the beats, say the beat 4:, or one ofthe seat portions, saythe seat portion of the valve opening for superheated steam, may be provided with an apron 6, as shown in Fig. 1, or an apron 6, as shown in Fig. 2, serving more ,or less to construct the relatlve passage, 1t
A valve system for controlling the propor- I tions of super-heated and saturated steam to be admitted to steam engines, comprising the combination of a double beat valve includ-. ing valve elements of substantially equal area controlling passages for superheated steam and saturated steam respectively leading thereto, and means including an apron constricting one of the passages whereby to insure maintenance of balance or said valve Y with unequal amounts of super-heated steam and saturated steam flowing through said passages, substantlally as described.
In testnnony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
ROBERT BAYLES ARMSTRONG. GEORGE PATERSON. Witnesses: ISABEL RoLLo, FLORENCE HOUSTON.
