Specification of Letters Patent.

Patented Aug.26, 1919.

Application filed March 31, 1919. Serial No.'286,595.

To all whom it may concern:

.Be it known that I, CHARLES E. Brennan, a subject of the King of Great Britaln, residing at Iroquois Falls, in the Provinceof Ontarioand Dominion of Canada, have 111- vented certain new and useful Improvements in Lamp-Extinguishers, of which the following is a specification.

This invention relates to lamps and more particularly to extinguishers therefor.

The principal object of the invention is to provide a simple and inexpensive device for extinguishing the lamp which will be automatically operative whenever the lamp to which the device is applied is tilted in any direction thereby preventing all danger of a conflagration.

Another object is to improve the construc tion of lamp extinguishers by providing an inexpensive and durable device which will not interfere in any way with the light giving capacity of the lamp to which it is ap plied and which will always operate with certainty whenever the lamp is given a sufficient tilt in any direction to render it liable to explode.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a side elevation partly in section showing the lamp burner equipped with the extinguisher constituting this invention,

Fig. 2 is a similar view taken in a plane at right angles to Fig. 1, and

Fig. 3 is a top plan View with the hood or guard shown removed with parts broken out.

In the embodiment illustrated, a lamp burner is shown comprising the usual body 1 having a wick tube 2 and gallery 3 with the usual hood or guard 4 pivoted thereto as shown clearly in Fig. 1.

An ordinary perforated base plate 5 is mounted at the top of the gallery around the wick tube and has depending therefrom an annular trough 10 divided into two sections by transversely arranged partitions 11.

In each of these sections adjacent to but spaced from the partitions 11 is a projection 12, and a seat 13 is formed between said projection and partitions to receive a ball 17. Two of these balls are employed, one

being mounted in each section of the trough as is shown clearly in Fig. 3.

.A bearing 6 is carried by said side face of the wick tube 2 and is designed to support a shaft 7 which projects laterally from said tube, one of said shafts being arranged at each end of the tube as is shown clearly in Fig. 1. This shaft 7 has an upstanding or laterally projecting finger 8 at its inner end to prevent its withdrawal and its outer end has a laterally extending arm 9, preferably weightcd at its free end and which end extends through the base plate 5 into the trough 10. The weighted arm of shaft 7 preferably extends to a point adjacent the bottom of the trough so that it will be p0- sitioned in the path of one of the balls 17, said arm being flattened so as to insure its engagement by the ball for a purpose presently to be described.

Carried by arm 9 parallel with shaft 7 is another shaft or red 16 to the inner end of which is fixed an upstanding extension 18.

An extinguisher cap is fixed to each of the extensions 18 as is shown clearly in Fig. 2. These caps may be of any suitable or desired construction and are designed to shut over the upper end of the wick tube to extinguish the face when so moved.

From the above description it will be obvious that the caps 15 are held in open position by friction which may be overcome by the forcible engagement of one of the balls 17 with the depending arm 9 of the shaft 7.

In the use of the device, the balls 17 are normally seated in the depressions 13 between the projection 12 and the partitions 11 as is shown clearly in Fig. 3 and should the lamp for any reason he tilted sufficiently to cause these balls to be thrown out of their seats over the projection 12 they will pass around the trough section in which they are mounted and engage the arms 9 disposed in their path with suflicient force to rock shaft 7 and close the cap 15 carried thereby, thus instantly extinguishing the lamp and preventing all danger of an explosion.

From the foregoing description, taken in connection With the accompanyingdrawings, the advantages of the construction and of the method of operation Will be readily apparent to those skilled'in the-art to which the invention appertains and While Ifhave the 'device shown is merely illustrative and j that such changes may be made asare Within the scope of the claimed invention. Having thus fully described myinvention, What I claim as new and desire to secure by Letters Patent, is V 1..A lamp burner including a 'Wick tube, a gallery and a perforated baseplate, an annular trough depending from said base plate, partitions. dividing said trough into sections and having seats thereimballs normally mounted in said: seats,v extinguishers pivoted in said Wick tube, and havingarms Copies of this patent may be obtained for zontally-disposed shaft revolubly mounted.

in said Wick tube, an arm depending from said shaft into said trough, an extinguisher carried by said arm extending over the top of said Wick tube when in closed position, a Weight movable in said trough, and means for normally retaining said Weight out of engagement With the arm extending thereinto.

In testimony whereof I affix my signature in the presence of twovvitnesses.

CHARLES E. BERNIER.
