SAFETY-EXTINGUISHER FOR LAMPS.

Specification of Letters Patent.

Patented Dec. 8, 1914;.

Application filed March 21, 1914. Serial No. 826,385.

To all whom it may concern Be it known that we, MELVIN E. Enron- SON and ARTHUR W. MoonnN, citizens of the United States, residing at Grantsburg, in the county of Burnett and State of lVisconsin, have invented certain new and useful Improvements in Safety-Extinguishers for Lamps, of which the followingis a specification.

This invention relates to new and useful improvements in safety attachments for oil burning lamps.

The principal object of my invention is to provide a snuffer or extinguisher which will automatically operate to extinguish the flame of the lamp wick in case the lamp is tampered with or accidentally overturned.

A further object is to so construct the extinguishing device that it will move into operative position immediately upon the dis placement of the lamp base from its normal position on the table or other supporting structure, unless the lamp is to be moved from one place to another and the person carrying the lamp holds the extinguisher in inoperative position by grasping a finger lug which is carried by the actuating rod of the extinguisher.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

With. reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure l is a vertical section taken through a lamp equipped with our automatic safety extinguishing device; and Fig.2 is a detail perspective view showing the main elements of the extinguishing attachment.

Before taking up the description of the details of construction of our invention, it is desirable to explain that while the device has been illustrated as applied to a particular form of oil burning lamp, and will be hereinafter described in that connection, the principles of the invention may be applied to any type of oil burning lamp by subjecting the device to a few minor and obvious mechanical changes.

In the drawings, the numeral 10 dcsignates as an entirety the oil container or body portion of a standard form of lamp. The container 10 is carried in the usual manner on a hollow base or casing 11, having a re duced upper terminal 12 of any suitable design. A burner, indicated at 13, is threaded in the neck 14.- of the container 10 in the well known manner.

The extinguisher or snuffer consists preferably in a sheet metal sleeve 15 which is mounted for sliding movement on the upper terminal of the wick tube 16, and is normally held in position below the exposed portion of the wick by means to be hereinafter described. As hereinbefore explained, the extinguishing device is so designed that it will operate automatically to snuff out the flame of a wick l7 wheneverv the base 11 is displaced from its normal position on a table or other supporting structure. As a means for accomplishing this result, there is provided an actuating rod 18 which is riveted or otherwise secured at its upper terminal to the sleeve 15, as indicated at 19. This actuating rod 18 is mounted for sliding movement through a tube 20, which extends through the oil container 10 of the lamp, as clearly shown in Fig. 1. This tube 20 extends diagonally through the container so that the lower terminal of the rod 18, indicated at 21, is considerably offset with respect to the vertical center line of the base 11.

Arranged exteriorly of the base member is a cup-shaped member or pan 22, Wl11Cl1 1s also formed of sheet metal, and 1s preferably circular in shape, being of considerable area so that it will engage flatly against the top of a table, and will not be likely to mar or scratch the surface thereof. Extending vertically from the member 22 and eccentrically with respect thereto is an arm 23, which is pivotally connected to the lower terminal of the actuating rod by means of a rock arm or lever 21 and a link rod 25.

The member 24- is pivotally connected at one terminal by a pin 26 to the upper terminal 0f the member 23, while its other terminal is pivotally connected by a pin 27 to the lower terminal of the member 25. As a means for supporting the member 2 1, there is provided a dependent arm 28 which is secured at its upper terminal to a partitioning plate 29 inserted in the lower end of the member 12. It will be seen upon reference to Fig. 1 that the member 2a is pivoted'ad= jacent its terminal 27 to the lower end of the arm 28 by a pivot pin 30.

The link rod 25 extends through an opening 31 foi med in the threaded. at its upper terminal, whereby it mav be engaged with a coupling sleeve 32, the upper end of which receives the terminal 21 of the actuating rod 18. A set-screw 33 is threaded into the coupling sleeve, and engages the member 10 for holding it against withdrawal. The head of the set-screw 33 is formed in the nature of a cylindrical ex tension, which serves as a fingergrip where by the operator may hold the extinguishing sleeve 15 in inoperative position when the lamp is moved from one table to another, as will be hereinafter fully explained.

From a central point of the member 22 extends a vertical sleeve 34:. This member 3 1 receives a vertical downwardly extending centering rod 35, the upper terminal oi which is soldered or otherwise secured to the member 10, as indicated at 3 6. A helical spring, indicated at 37, surrounds the tubular sleeve 3%, and the rod 35, and has its upper terminal secured to the partitioning plate 29 and its lower terminal secured to the outwardly extending flange 38, which is formed on the lower terminal of the member 3 1. This spring 37 is of the expansive type, and normally serves to hold the pan 22 exteriorly of the hollow base casing 11. I

The actual construction and arrangement of the several parts of this invention being thus described, it now remainsto explain the manner in which the sleeve 15 is automatically actuated to extinguish the flame of the lamp wick simultaneously with the displacemento i the base member 11 "from its normal position on a table or other supporting structure on which the lamp has been placed.

Itwill be seen in lamp is placed on a table, the pan 22 lies in the plane of the lower edge of the base member 11, and that when the pan is in this position the terminal 27 of the member 2a is depressed to such a pointthat thesleeve 15 is held with its upper edge below the. upper edge of the wick tube 16 through the medium of the connectingrod 18. It will be seen that the pan 22 will be projected beyond the confines or limits of the base member 11 by means of the sleeve 37 in the event that the lamp is lifted from the table or is over-turned, causing the base to be displaced. The projection of the pan 22v from beyond the limits of the base member 11 will, o1. course, swing the mem er as on its pivot 30, causing the member 25 p to move upwardly through the opening 31, resultantly-causing the sleeve 15 to be slid upwardly on the wick tube 16 by meansoii the actuating or connecting rod 18. NVhen the sleeve 15 isjthus slid upwardly on the member 16, it incases base rnember 11, and is Fig. 1 that when the the projecting terminal of the lamp wick, and, of course, extinguishes the flame by cutting oil the supplyof air necessary to support combustion.

In case the user of the lamp wishes to move the lamp from one place'to another without extinguishing the flame, the sleeve 15 'may be held in inoperative position by holding the member 37 with the fore-finger or thumb as may be most convenient. It will be obvious that should the person carrying the lamp accidentally drop it, the sleeve 15 will be immediately projected into operative position by the sleeve 37, and iur ther that should a child unfamiliarwith the igniting device attempt to liitthe lamp from itsproper place, i will immediately move into operativeposinot.

In reduction to practice, it has been found that the form of this invention illustrated in the drawings, and referred'toin the above the extin 'uishin" device description as the preferred embodiment, is

the most eflicient and practical; yet realiz ing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the fact that Various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of this invention, as defined in the appended claims.
