LUIGI MOMBARUZZO, OF NEVI YORK, lil'. Y., SSIS-NOE, 0.?? GNE-TIEED T0 li-LE? BENVSSUTO AND ONE-THIRD T@ OLENDO G. CECCARlN, BOTH OF NEVI YORK, N. Y.
Application filed April 12,
To all whom it may concern.'
Be it lrnown that I, LUIGI MoMnAnUzzo, a citizen ot ltaly, residing in New York city, county ot New York, borough of Manhattan, and State of New York, have invented certain new and useful improvements in Reducing Valves,y of which the following is a full, clear, and exact speciiication.
My invention relates to reducing valves and refers particularly to reducing valves operative by temperature means.
llVhile the device oiI my invention is broad in its scope ot application, l reter to its particular use with gas burners simply as a means of illustration and without any limitation to that particular' use.
Grave danger is always incident to the use of gas for illuminating' and heating purpose, in that the accidental, or deliberate, extinguishment ot' the flame without the closing of the pipe valve allows a tull head ot gas to escape from the burner, Jrreopiently resulting in the loss of lite.
The same result is obtained, if the pipe valve is accidentally, or deliberately, opened without ignition of the escaping gas.
The device of my invention overcomes these and many other serious and objectionable results incident to the use ot the usually employed valve.
In the employment of the reducing valve oi' my invention, the extinguishment of the flame automatically reduces the flow ot gas to a non-dangerous and unob'jectionable degree, allowing a flow suiiicient only tor purposes of slight ignition when desired.
Further, in the employment of the reducing valve of my invention, the opening oi the usual valve without ignition does not allow the full How ot gas but maintains it in the non-dangerous and unobjectionable degree above mentioned.
Further, the employment of the reducing valve oi' my invention does not interfere with the usual illuminating, or heating, properties ot the burner, because the ignition of the gas escaping through its reduced area automatically opens the reducing valve to its fullest extent, thus allowing the full flow of gas.
It is evident, therefore, that the employment of my reducing valve allows a reduction in the amount or" gas flow due to temperature control and, in the specifically de- 1921. Serial No. '460,723.
scribed example of its application, a reduc- Figure 2 is a section through the line 2--2 of Figure 1.
Figure 3 is broken vertical cross-section oi a modified term ot the device ot my invention. L
-Figure l is a bet-toni view of the closure means oi' Figure 3.
The particular iorm of a device ot my invention applied to a gas light equipment, as shown in the accompanying drawings, coinprises a gas pipe 10, carrying the key valve 11 and the burner 12 in which is inserted ordinary gas tip 13. Fixedly attached to the inner tace oit the wall of the gas tip 13 is a transverse partition 14, having the larger aperture 15 and the smaller aperture 16. Supported by the partition 14 is a thermostat 17, the other end oi? the thermostat 17 having iixedly attached a, wire 18 extending through the aperture 15 and carrying the ball 19.
Figures 1 and 2 show the device in operation with the gas ignited. The gas under these conditions iiows freely through the apertures 15 and 16 and the heat produced by the iiame 20 is transmitted to the burner 12 and the thermostat 17 retains the aperture 15 in an open position, as shown. Should the ilame 2O be extinguished, the burner 12 will cool and the thermostat 17 will raise the ball 19, closing the aperture 15 and preventing the How of gas therethrough. The only gas that can then escape through the tip 13 is that passing through the aperture 16, which is so small in amount as not to be dangerous, or objectionable, and this can, ot course, be entirely eliminated by closing the key valve 11.
In order to lightthe gas, the key valve 11 is opened and the gas passing through the aperture 16 is lighted at the tip 13 and, within a few seconds, the heat thus produced causes the thermostat 17 to open the aperture 15 by lowering the ball 15, thus giving the full illuminating eiiiciency.
,lt will thus be seen that the only gas that can escape, when it is not ignited, is that passing through the small aperture 16, even it the key valve 11 is accidently left open and that the ignition or. this small amount ol? will automatically open the larger aperture l5.
ln the modiied form of my device, shown in Figures 3 and die, the partition 14 has but one cpening 2l which -is capable of being thermestatically closed by the member 22. which has a small recess 23 through which a small amount ot gas can escape. similarly as through the aperture 16 in the device oT' Figures l, and
The theri'nostat may be of any shape and material. or materials` which will thermon statically reduce the passage area, and it may be attached to any suitable portion ot the device.
lt also evident that the apertures may be of various sizes and in various positions within the device for reducing the 2Fas passage area.
l do not limit myself to the particular size7 shape, number, material or arrangement of parts as shown and described, all ot which may be varied without going beyond the scope of my invention as shown, described and claimed.
llllhat l claim is l. ln a gas burner, in combination, a chamber, a transverse horizontal partition within the chamber having an opening therein, a U-sha ped thermostat entirely within the upper chamber ixedly attached at one end. a wire carried by the free end of the ther mostat and extending through the partition opening, a valve member carried by the wire .vithin the lower chamber and pendant from the thermostat and capable of free vertical movement. to open and close the partition openingI` the thermostat allowing the valve member to be free from the opening at normal temperatures and carrying the valve member vertically upwardly closing the opening at temperatures above the normal.
2. ln a gas burner. in combination, a chamber`r a transverse horizontal. partit-ion .vithin the chamber having a larger opening and a smaller opening therein. a U-shaped thermostat entirely within the upper chamber tixedly attached at one end a wire carried by the tree end ot the thermostat and extending through the larger partition opening, a ball carried by the wire within the lower chamber and pendant from the thermostat capable of free vertical movement to open and close the larger partition opening, the thermostat allowing the hall to be free from the opening at normal temperatures and carrying the ball vertically upwardly closing the opening at temperatures above the normal.
Signed at New York city in the county of New York and State of New York this 11th day of April, 1921.
