GAS-BURNER.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed September 1, 1608. Serial No. 451,216.

To all whom it may concem:

Be it known that I, THOMAS STANLEY PHILPOTT, a subject of His Majesty the King ployed and a pilot light for re-lighting the of Great Britain and Ireland, residing at 256 Lambton Quay, Wellington, in the Provincial District of lVellington, in the Dominion of New Zealand, haveinvented cer-' tam new and useful Improvements in or Relating to Gas-Burners, of which the followmg is a specification.

This invention relates to gas burners:

wherewith incandescent mantles are emmain supply of gas to the burner.

Hitherto a by-passfor admitting a supply of'gas to a pilot light has been constructed 1n 1 the following way In a tap fitted to a burner, and-which is operated each'time the burner is brought'into use, agroovehas beenprovided in the plug of the cock, whichgroove allowed a supply of gas to pass to a pilot light when the cock was turned oif. In

another system, which is usually designated a pilot service, a number of burners are supplied from one common gas main and" the pilot lights for such burners are supplied from an independent and common pilot gaspipe. In this case the whole of the burners are extinguished by a cock usually at some distance from the burners and the pilot gas tube is connected to the main on the side of the tap remote from the burners. The pilot gas was led to the gas burner by means of asmall tube connected to a nipple outside the burner and it was therefore necessary to make a considerable number of bends in the small tube and further there was difiiculty in removing the socket by which the said tube was connected to its nipple in the case of renewals, or for cleaning purposes. The result was that corrosionrapidly set up in the bends of the small tube and it was impossible to remove the tube and clean it owing to thebends preventing the entrance of a wire and the difliculty or impossibility of removing the socket after it had been in use for some time.

The object of my invention is to provide a ilot tube in a pilot service which is practically straight so that there is very little lodgment for deleterious matter within the tube and so that a wire can be readily passed through the tube, the parts being so constructed that the burner itself can be readily taken apart and cleaned.

A further object of my invention is to pro vide means whereby any burner in a cluster of burners supplied by a common gas main can be readily regulated and adjusted independently of the other burners in the cluster whereby the illuminating power of the burners may be readily equalized. The drawings illustrate the form which I prefer my invention to take.

Figure 1,'is an elevation partly in section of a chandelier having three burners, Fig. 2, is a sectional plan on line A A Fig, 1, Fig.

3, is a diagrammatic view showing the piping.

The main gaspipe 1 is connected to a base consisting of a boss 2 having an integral well 3. Branch pipes4= lead from the well 3 and are supplied at their outer ends with a base 5 upon which is supported a burner 6 known as the Avon top burner. The base 5 has a neck 7 and a collar 8. The gas passing from each branch pipe 4 to its burner is readily regulated by a screw 9 having a milled head 10 and a conical end 11. The

said conical end being capable of closing upon a valve seat-12 formed in the burner. A lock-nut 14 is adapted to lock the screw after its adjustment has been efiected. The pilot gas tube 15 is connected to the boss 2 wherein a triangular channel 16 is formed, communication between the apexes of the triangle and the exterior of the boss being closed by screws 18. Holes 19 are formed from the exterior of the boss to the triangular channel 16 and are fitted with plugs 20 provided with holes 21 extending throughout nearly their whole length.

Holes 22 at the end of the'plugs and at the top thereof meet the holes 21, which are traversed by screws 23 having holes 2 and by turning the screws 23 the holes 26L will allow more or less gas to pass as desired.

Each hole 22 receives a pilot tube 26 which is practically straight and passes through a groove 27 in the collar 8 and thence through the burner 6. The tube 15 is carried back to a position beyond the main tap 28 (see Fig. 3) where it is connected to the main by a tee 29 or anyother ordinary means.

I have shown the'pipesl and 15 exposed to view, but if desired they may pass inside a casing in a well known manner.

When it is desired to clean the pilot tube 26 or the base '5 the burner 6 is unscrewed from the base 5 and the pipe 26 is unscrewed from the plug 20 and the base is then unscrewed from the branch pipe 4: and the screw 9 removed leaving all the parts in means for supplying gas tothe base, a

burner fitting the base, a hollow plug projecting below the collar and a practically straight pilot tube screwed into the-plug and passing through a groove in the said collar and into the interior of the burner, substantially as set forth.

2. In a gas system employing apilot service, a burner base having a neck and collar, means for supplying gas to the base, a burner fitting the base, ahollow plug passing below the collar, a practically straight tube screwed into the plug and passing through a groove in the-said: collar and into the interior of the burner, and a screw fitting the base and having a milled head and conical end adapted toclose upon. a valve seat withinthe base and: a lock-nut upon. the screw,- substantially as set forth.

3.. Ina gas system' employing a pilot service, a burner base having a neck. and collar,

a base consisting of a bossand an integral well, branch pipes leading from the said well, a burner base having a neck and collar with which the branch pipe communicates, a burner fitting the base, a hollow plug projecting below the collar and a practically straight pilot tube screwed into the plug and passing through a groove in the said collar and into the interior of the burner, a pilot gas pipe connected tothe base and communicating with the hollow plug, substantially as set forth.

41:. In a gas system employing a pilot service, abase consisting of a boss and an integral well, there being a triangular channel in the boss, screws closing the apexes of the channel, hollow plugs communicating with the channel,.pilot tubes communicating with the hollow plugs, and means for supplying gas to the channel, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two witnesses.
