OIL-LAMP.

To all whom it may concern;

Be it known that I, JAMES BRYsoN, a citi- Zen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Oil-Lamps, of which the -following is a specification.

- This invention relates to a provision for an oil lamp rendering it safe against ire or explosion consequent on upsetting the lamp. This object is attained by producing the wick tube of the burner to adjacent the lower end of the oil reservoir and providing a valve that will close the lower end of the tube when the lamp is canted to an angle.

The invention is particularly described in the following specification, reference being made to the drawing by which it is accompanied, in which:

Figure 1 is a vertical section through a domestic lamp with its burner tube and hood. Fig. 2 is a similar view with a slight modiication, the plane of section being across the narrower dimension of the wick tube. Fig. 3 is a section on ythe line 3-3 of Fig. 1.

In these drawings 2 represents the bowl or oil reservoir of the lamp, 3 the burner and its connected parts, and 4C the cap or bushing of the reservoir into which the burner is threaded.

Inthe lower part of the bowl 2 a depression 5 is formed adapted to receive a ball 6 of reasonable size and weight.L

The wick tube 7 of the burner instead of terminating as is customary, just below the feed wheels by which the wick8 is raised and lowered in the burner, is carried down adjacent the bottom of the lamp and terminates a short distance above the upper side of the ball 6 and in the lower end of this tube 7 is inserted between the end of the tube and the ball a valve 9 shaped in any suitable manner to retain its position in the tube and adapted to close tightly against the of the valve seating on the lower edge of' Vthe wick tube. This provision may consist of a crimp 10 in one or both sides of the lower edge of it when the ball 6 rolls along the sloping sides of the depression if the lamp is canted to a spilling angle.

Means is provided adjacent the lower end of the wick tube to prevent the end of the wick intruding to interfere with the action wick tube, as in Fig. 2, or by securing two small pins 11 across the thickness of the tube, as in Fig. 1.

speciecation of Letters Patent.

Application led March 30, 1915. Serial No. 18,136.

.If considereddesirable in applying the device to existing lamps where the wick tube terminates immediately. below` the feed wheels, the required supplementary wick tube extension may, as shown in Fig. 2, be connected to the bushing 4 which is secured to the neck of the bowl to receive the burner. IVith this provision, if the lamp is upset or canted to an angle approaching the hori- Zontal, the weight of the ball endeavoring to roll out of the depression 5 will engage the underside of the valve 9 and will close that valve on the lower edge of the wick tube 7 and thus prevent spilling the oil through the tube.

Although illustrated as applied to an ordinary domestic oil lamp having a glass or porcelain vessel to contain the oil the device is equally applicable to lamps having metal vessels, and particularly to that class known as storm or stable lamps, which latter are more liable to be upset about a stable or barn.v

I am aware that prior to my invention lamps have been made wherein the wick tube has been extended toward the bottom of the oil reservoir and provided with a valve which is designed to close the end of the wick tube and prevent escape of the oil, and that balls have been used to eEect the closure of the valve; but these devices have been complicated in the valve operating mechanism, and where a ball has been used it has not been introduced into a depression formed for it in the bottom of the vessel but has been supported in an extension depending from the wick tube and has on that account been limited to an ineffective size. larged beyond what was required to merely pass the wick and the wick tube has consequently contained an amount of spillable oil sufficient to cause a fire.

Having now particularly described my invention, I hereby declare that what I claim as new and desired to be protected in by Letters Patent, is:

1. A safety device for an oil lamp, said device comprising in combination, an oi reservoir having a depression in its bottom in alinementv with` the wick tube of thel burner, a ballwithin the depression, an eX- tension Jfrom the wick tube of the burner terminating adjacent the ball in the depression, and a valve resting on'the ball and adapted to be acted on by it to close the Further the wick tube has been en? lower end of the wick tube when the lamp is tilted at an angle where the ball will tend to roll out of the depression.

2. A safety device for an oil lamp, said device comprising in combination, an oil reservoir having a depression in its bottom in alinement with the vwick tube of the burner, a ball within the depression, an extension from the wick tube of the burner terminating ladjacent the ball: in the depression, said extension having means adjacent thel lower endl for limiting movement of the wick thereto, and a valve resting on the ball and adapted to be acted on by it to close the lower end of the wick tube when the lamp 15 is tilted at an angle where the ball will tend to roll out of the depression.

In testimony whereof I aHiX my signature in presence of two witnesses.
