SAFETY CAR-LAM P.

`SPEC33:"111AA'J)ION forming part of Letters Patent No. 252,098, dated January 10, 1882,

Application filed July 23, 1881. (No model.)

To all whom it mayconcera:

Be it known that I, CHARLES E. GRANNIss, a citizen ot' the United States, residing at New Haven, inthe county ot' New Haven and State of Connecticut, have invented certain new and usefulImprovementsin SnfetyCanLamps; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings,l and to letters or figures ot' reference marked thereon, which form a part of this specification.

This invention consists, as hereinafter described and claimed, in an attachment for railway-car landother lamps, whereby the flame will be surely and automatically extinguished upon the lamp being overturned or subjected to concussion.

In the drawings, Figure l represents a sectional elevation, showing a portion of a lamp withwmy improvement applied thereto. Fig. 2 is a side elevation, partly in section, of my attachment secured to a lamp-burner. Fig. 3 shows in detail a portion otI the mechanism,

and Figs. 4t and 5 show modifications.A

This attachment, while more especially designed for application to car-lamps to insure the automatic and instantaneous extinguishment of the tlame of the lamp in the event of a collision or other accident occurring where the overturning or presence in said cars of a e lighted lamp would be a source of danger, is

also adapted for application to lamps of various constructions used in vehicles, buildings, and other places.

A represents the body or oil-re=ervoir ot a lamp of any suitable construction.

B is the burner, ot' ordinary construction.

C is the wick-tube, and I) the wick. To one side of the wick-tube C are secured the upper ends, a a, ofthe rods or plates E E. The up-l per ends, a, are straight, as shown, to adapt them to be readily secured to the tube C. These rods or plates E extend down beyond the bottoni of the wick-tube, from which point they flare outwardly, as at b b. The lower ends are perforated or recessed to receive the trunnions or pivots c c, upon which is swiveled a rin g, F. Withiuthis ring F is pivoted, upon trunnions or pivots d, arranged transversely of the position of the trunnions or pivots o, a weight or pendulum, G. By means of these pivotalconnections ofthe weight to ther-ing and the ring to the rods or plates said weight is capable of a rocking movement in any desired horizontal direction. Within the top of this weight or pendulum Iform a recess,.e, to receive the lower end of a rod, H. This recess e may be of any depth desired, according to the amount ot' concussion it is desired the lamp shall withstand, a shallow recess admitting ot the pendulum being forced away from the rod more easily than when the recess is deep, aswill be bereinafter explained. The rod H is encircled at its upper end by a spiral spring,f, resting at its lower eud 011 a collar, g, upon the rod, and secured at its upper end in any suitable man- .ner to admit of the vertical spring movement I is a hooded extinguisher, which ishinged at J to the la1np-burner, and is pvoted at K to a hinge-jointed rod, L, whose lower end is attached to the upper end ot' the spring-rod H, as clearly .shown in Fig. 2, so that on the upward movement of said rod H, to raise the extinguisher to permit ofthe lightingofthe lamp, said extinguisher will have imparted to it both a vertical and a rearwardly'horizontal movement, and ou the downward movement of said rod H will descend vertically, and move also in a forward horizontal direction, as shown in dotted lines, Fig. 2, to cover the wick-tube and extinguish thefiame.

`M represents a slotted spring-plate, hinged at one end, h, to the burner, and when the rod H is in its raised position, springing up to afford support thereto, the button or boss i resting upon said spring-plate M and affording a hearing-surface for said plate to operate upon. The free end of the plate M is curved! upwardly at N, in order that it may be readily raised, the raising of which draws up the rod H and allows its lower end to enter the depressed upper end of the pendulum. O represents the wick-raising device, which is of ordinary con# struction.

In the modification shown in Figs. 4 and 5 I have shown` a device ior drawing down the wick on the pendulum being jarred out ot' vertical position on being subjected to concussion.

In lhisconstruction l dispense with the hooded extinguisher, and in lieu thereof I serrate the lower part of the rod H at c.- A spur-wheel, l, is mounted upon a short shaft or cross-bar, fm, secured with capability of rotation therein in the rods or plates E. One or more segments, n, are mounted upon the shaft m, with their serrated faces engaging the wick, as shown in Fig. 4. On the pendulum beingjarred out ot' engagement with the rod H the rod will fall and cause the spur-wheel lto revolve, which in turn imparts a rotary movementto the crossbar or shaft m, and, forcing the segment or segments n down at the same time, draws the wick down below the top of the wick-tube, thereby effectually extinguishing the llame.

v The device herein described and shown is a very efficient self-acting lamp-extil'lguisher, as, on the lamp being subjected to more than an ordinary jarring, such 'as being knocked down or shaken by the vehicle or car to which it is secured being overturnedor coming into collision with another object, the concussion will cause the pendulum to swing away from the rod H. The rod H will then drop down, and either force the extinguisher l down upon the top of the wick or draw the wick down Wit-hin the tube, as the case may be, depending upon which arrangement of devices herein described is used.

Having thus described my invention, Awhat I claim as new therein is- A l. The combination ofthe pendulum or weight G, having recess e in its top,ring F, trunnions or pivots c d, rods or plates E, rod H, and encircling spring f, and the hooded extinguisher I, pivotally connected to the top of the rod H, substantially as and for the purpose set forth.

2. The combination of weight G, rin g F, pivots c d, spring-rod H, hooded extinguisher I, and hinged lever M.

The combination of the weight or pend-ulum Gr, having recessed upper end, the springrod H, adapted to rest within the recessed portion of said Weight, the vrods or plates E, ar ing at their lower ends, the ring F, pivoted at c to said rods, and having pivots d, upon which the weight or pendulum G is supported, the hooded extinguisher I, secured to the top ot'- the rod H, andthe hinged lover M, substantially as and for the purpose set forth;

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

CHARLES E. GRANNISS.
