GAS-BURNER.

Specicaton of Letters Patent.

Application tiled February 91 1906. Serial Nm 300.351.

Patented Dec. 17, 1907.

To all whom it may concern.'

Be it known that I, AUGUST MEYER, a citi- Zen of the United States, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification,

This invention relates to improvements in gas burners, and more particularly to a burner especially adapted to be operated by a clockwork or time mechanism, the burner being particularly intended for use upon street lamps.

While the burner about to be described may of course be operated by hand, yet as before stated, it is especially designed to be operated by a time mechanism, and particular attention has been paid to the construction of the burner with a view of providing a valve and other operating parts that will require a minimum amount of power to operate it, or such power as can be practically derived from a clockwork or time mechanism of simple construction.

The burner belongs to that class of burners in which a by-burner or pilot lighter is employed to maintain a small flame for the purpose of igniting the main volume of gas as it issues i'rom the main passage of the burner.

The main obj ect of this invention is to provide a burner, the valve and other operating parts of which will be of simple construction and require a minimum amount of power and degree of movement of parts for its el"- iicient operation, the parts being so constructed that friction and liability to stick, as a result of gas deposits or other causes, are practically eliminated.

In my application ,filed November 4, 1905 Serial No. 285,891, I fully illustrated and described a novel clockwork mechanism in connection with a burner of construction different from the burner about to be described, which mechanism may be equally well adapted to operate this burner.

In Figure 1, of the drawings forming a part of this application, a clockwork or time mechanism is shown in connection with the burner, which mechanism corresponds to that illustrated in detail in my application referred to. However those parts of both burners which directly cooperate with the elements of the time mechanism are the same, that is to say this burner, as well as the burner of my former application, is proat pre-determined intervals by devices actuated through the clockwork or time mechanism to accomplish the operation of the valves to light and extinguish the lamp.

In the drawings illustrating the invention: Fig. 1 is a front elevation of the burner, showing in connection therewith in front elevation, a clockwork or time mechanism, or such of the parts thereof as is necessary to show the connection between said mechanism and that part of the burner operated upon or actuated by the mechanism, to light and extinguish the lamp. Fig. 2, is a longitudinal central section through the burner body, showing the main and pilot gas passages, and the ports or openings through which communication is established vided with a rock shaft adapted to be rocked between the gas chamber and said passages. A

Fig. 3, is a transverse section taken on about line .fr-, of Fig. 1. Fig. 4 is a section taken about on line y-fy of Fig. 3 showin then valves in elevation, one position o the valves being shown in dotted lines. Fig. 5, is a side elevation and plan of one of the valves. Fig. 6, is a top plan view of one of the conduits which form valve seats for the valves, and through which the gas passes, which gas is supplied from a suitable source to the main and pilot7 passages in the burner. Fig. 7, is a side elevation of the rock shaft to which the valves are attached, and Fig. 8, is a front' elevation of the burner showing a slight modification adapting it to be operated by hand, either when the burner is used in connection with the time mechanism, or alone.

Referring to the drawings: The numeral 1 indicates the burner body which has two passages therethrough, 3 and 4; the passage 3 being for the passage of the main volume of gas, or that which is intended for the lighting volume; and that designated by 4 being for the gas supplying the pilot77 Each passage is closed at its bottom by screw plugs forming parts of needle valves 5, by which the flow of gas and its pressure may be regulated.

The numerals 6 and 6 are ports opening into the burner passages, the port 6 being for the admission of the main or lighting volume of the gas and 6 for the gas 'supplying the pilot. Fitted into these ports are conduits 7 and 7 which extend a short distance into a gas chamber 8, formed at the rear side of the burner. Each conduit has a passage therethrough as shown, for the obvious purpose of permitting the gas at proper times to pass from the chamber 8 to one or the other of the burner passages; The conduits are tapered at the ends within the chamber, as indicated at 9, and form valve seats for two disk valves 1() and 10. ates in connection with and controls the supply of gas to the main burner passage, while the valve 10 operates similarly with relation to the conduit 7. The valves are preferably in the form of thin disks, and each is provided with an eye 11 by means of which they are loosely connected to a thin segmental plate 11/, which in turn is rigidly connected to a rock shaft 12, which passes 4,through and has a bearing in an opening 13 in the body. To the front end of the rock shaft a rocker arm 14 is rigidly attached. This arm is provided with two short pins 15 .and 15', for a purpose which will presently become apparent. interposed between the rocker arm 14 and the front surface of the casting is a thin leaf spring 16, which exerts a tendency to keep the slightly tapered or beveled portion 17 of the rock-shaft snugly against a corresponding seat in the rear wall of the burner body.

The numeral 18, designates a light spring having its lower end attached to a pin 19 in the chamber 8, andits upper end looped over a short pin 20 carried by the segmental arm 11. This spring is for the purpose of holding the valves properly seated upon their seats, and acts in addition to the gas pressure which would also have a tendency to seat the valves. The spring is so are ranged that when the rock-shaft is rocked until the pin 20 passes the center of the shaft, said spring will instantly seat the valve intended to be closed, and hold it properly seated until the reverse operation takes place.

Connected to the lower part of the burner body, and which may' form a part thereof, is a gas connection 21, internally threaded for the reception of a gas-pipe 22, which in the arrangement herein shown, and more par ticularly in dotted lines Fig. 1, passes around the clockwork or time mechanism casing 23, and is led into another gas connection 24, by which last connection the whole device is adapted to be attached to the gas-pipe sup plying the gas to the street or other lamp.

In Fig. 1, the burner is shown provided with a bracket 25 by which, and by means of screws 26 it is attached to the upper side of the casing 23. The numeral 27, designates two rods which are suitably guided in a bracket 28 on the front of the burner` body. These rods are identical in construction and function with those shown in my application hereinbefore referred to, and they are actuated by the clockwork or time mechanism at The valve 1() operpre-determined intervals or times. These rods move vertically and the movement of one or the other brings it into engagement with one or the other of the pins 15 or 15 on the rocker arm 14, for the obvious purpose of causing the valve, through the medium of the rock shaft 12, to be operated to establish communication between one or the other of the burner passages and the chamber 8, as the exigencies of the case may require.

It is highly desirable in burners of this character that the pilot lighter be extinguished when the lighting volume of the gas is turned on, and that it remain extinguished while the lamp is lighted, as thus a consider- `able amount of gas is saved where a great number of burners are involved asin the case where a city is lighted. It is important too that the burner and its parts be so arranged that the pilot" will be invariably lighted from the dying flame of the mainburner as it is being extinguished. When this burner is used in connection with the time mechanism, for which it is more particularly designed, the movement of the rock-shaft and valves can be regulated to the greatest nicety, closing one of the valves and opening the other, quite slowly or in fact with any degree of rapidity that the efficient operation of the device may require. With a comparatively slight movement of the rock-shaft and valves, consuming probably five seconds, the liame of either the main or pilot burner will be caused to die slowly, giving either the one or the other as the case may require, ample time to light.

In my application No. 285891, I describe and illustrate a means for accomplishing a slow movement of the rods 27 when the hour is reached at which the lamp is to be lighted or extinguished. In that application the movement of the rods at pre-determined times is accomplished by means of or with the aid of cams, and it merely becomes a question of shaping the operative cam surface to produce the desired movement of the rods.

As before stated the casing 23 contains a clockwork or time mechanism having suitable dials and indicators thereon denoting the time when the lamp is to be lighted and extinguished and to denote the time of the day. These features are all fully described in my application hereinbefore referred to and need no further description here.

In operation, with the parts as shown in full lines in the drawing, communication between the chamber 8 and the pilot passage is n established, inV which the pilot lighter will be burning, while the main burner passage is closed. When the rock shaft is rocked toward the pilot lighter, the valve 10 will be lifted from its seat, establishing communication between the chamber 8 and the main burner passage, while the valve 10 Will be seated upon its seat cutting off communication between said chamber and the pilot passage, and the spring 18 which has been slightly tensioned, or rather has had its tension slightly increased by the movement of the shaft, will when it has passed the center of the shaft, exert a sudd en downward pull upon the segmental plate ll', and thus cause the valve 10 to be properly seated.
