To 61/, w/wm/ it Wl/H/y concern:

Be it known that I, THOMAS SAMUEL TAR- LING, a subject of the King of England, residing at 17 Tess road, Fleetville, St. Albans, in the county of Hertford, England, have invented certain new and useful Improvements in or Relating to Oil-Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to oil-lamps of the type known as safety-lamps, and has for its chief object to insure the immediate automatic extinction of the lamp in the event of its being overturned or accidentally lifted or tilted out of the perpendicular, while at the same time providing means whereby it may be intentionally lifted and carried about with out being extinguished.

In order that my said invention may be clearly understood, I will describe the same, with reference to the accompanying drawings, which show, by way of example, methods of applying my invention to a lamp provided with a single-wick tube and with double-.wick tubes.

On the drawings, Figure 1 is a vertical section of a single-wick lamp fitted with my improvements. Fig. 2 is an elevation of the extinguisher mechanism seen in position around the wick-tube, the outer fittings of the lamp being removed. Fig. 3 is a side elevation of Fig. 2, showing the extinguisher mechanism. Fig. 4 is a similar view to Fig. 3, but showing the extinguisher mechanism closed. Figs. 5 and 6 show details hereinafter referred to. Fig. 7 is a similar view to Fig. 1, but showing the mechanism adapted to a duplex-burner lamp. Fig. 8 is an elevation of the extinguisher mechanism. Fig. 9 is a side elevation of Fig. 8 with the extinguisher mechanism out of action. Fig. 10 is a similar view to Fig. 9, but with the extinguisher mechanism in action.

The same letters and numerals of reference are employed to denote the same parts in all the views.

Referring to Fig. 1, a is the body of the lamp, and b the container. The container is made, preferably, of metal with two vertical tubes 0 and d extending upward from the bottom. 6 and are two rods which pass vertically upwar through the two tubes 0 and d. g is a cross-bar connecting the lower ends of the rods 6 and f, and to the middle of the said cross-bar g is connected another rod h, provided with a weight i at the bottom. The cross-bar g projects through two vertical slots on either side of the diameter of the narrow portion of the stand or casing a. is a loose collar extending.circumferentially around the stand a near this part. The tops of the rods 6 and f are provided with two caps 7c and Z, rigidly connected to the tops of such rods and telescoping on the tubes 0 and d. m is a ring shown in plan at Fig. 5. This ring is attached to the tops of the caps at 76 and Z. n is a plate which is seen detached and in plan at Fig. 6. This plate is provided with a slot 0, through which the wick passes. To the plate n are attached on either side small rods p and q, passing through the guard-plate 1", and between the plate 0 and the guard-plate r and around the said rods p and are placed helical springs s andt in compression. To the tops of these rods p and Q are connected two crosspins a and i), which slide in slots to and :20, formed in the extension pieces or tails attached to the extinguisher flaps y and 2, which are of the ordinary construction and are pivoted to the wick-tube at Z.

The action of a lamp constructed according to this method of carrying out my invention is as follows: When it is required to raise the lamp without ext nguishing it, the stand is gripped by the hand around the loose collar and the pressure brought to bear on the crossbar 9 prevents the extinguisher mechanism coming into action. On the other hand, should the lamp be overturned. or be released by the hand the weight 1' will cause the crosspiece 9 to descend and draw the rods 6 and f downward, when the ring m will descend, and with it the plate it, under the action of the springs s and t, which are in a state of compression, and. the pins u and o, sliding in the grooves w and 0c in the extension-pieces on the extinguisher-flaps. will cause these flaps to close on either side of the wick and extinguish the light, as shown at Fig. 4.

It should be observed that the plate a is not attached to the ring m, so that the upper portion of the lamp with the wick can be removed for purposes of cleaning.

Referring to the lamp shown at Figs. 7 to 10, a is the body of the lamp, Z) the container through which a vertical tube 2 extends. 3 is a vertical rod provided at the bottom with a weight 4. 5 isa pin provided with a button 6 and a spring 7 to keep it normally away from the rod 3. 8 is a crossepiece attached to the rod 3, under the which the pin 5 takes when it is required to prevent the descent of the rod 3. 9 is a cap fitting over the top of the tube 2 and working with the rod 3. 10 is a cross-piece shaped as shown at Fig. 8, carrying two rods 11 and 12. 13 is a guardplate. 14 and 15 are two helical springs under compression between the piece 10 and the plate 13. The upper ends of the rods 11 and 12 work in slots 16 and 17 in the levers 18 and 19, which are pivoted at 20 to the bearingpiece 21, attached to the top of the guardplate 13. The opposite ends of the levers 18 and 19 are provided with slots 22 and 23 in which pins attached to the sliding pieces 24 and 25 work. Pivoted to the sliding pieces 24 and 25 are the extinguisher-flaps 26 and 27 and flat springs 28 and 29 are provided which tend to force the said flaps 26 and 27 over the wicks.

The action of a lamp constructed according to this method of carrying out my invention is as follows: When it is desired to raise the lamp without extinguishing same, it is simply necessary to push in the button 6, thus causing the pin 5 to take under the piece 8, as shown dotted at Fig. 7. This prevents the extinguisher mechanism coming into action. On the other hand, when the lamp is raised or dropped without pressing the button 6 the rod 3 will descend under the action of the weight 4, and consequently the cross-piece 10 will descend under the action of the compression- springs 14 and 15 and the rods 11 and 12 will be drawn down, causing the two levers 18 and 19 to turn upon their fulcrums at 20 and the sliding pieces 24 and 25 to rise, lifting the flaps 26 and 27, which under the action of the flat springs 28 and 29 spring over the wicks, and thus extinguish the light, as shown at Fig. 10. V

As in the previous case, owing to the construction of the extinguisher mechanism the top of the lamp can be detached from the body of the lamp and again attached thereto without trouble and without disturbing the working of the mechanism.

It will be seen that the form of the lamp may be varied, while retaining the principle of extinguisher mechanism kept out of action by means of rods passing through the body of the lamp and resting on the surface on which ,the lamp stands when in its upright or normal position.

What I claim, and desire to secure by Letters Patent of the United States of America, 1s

In a lamp, the combination of the lampbody, a burner-support secured to the top of said body, said burner-support being provided with a stationary guard-plate, springoperated rods passing through said guardplate, extinguishing devices carried by the upper parts of said rods, springs located beneath said guard-plate and surrounding said rods, a support for said springs, a weighted rod centrally located in said lamp and carrying a portion adapted to engage with said support, normally preventing its downward movement, and a part adapted to engage the hand of the operator and prevent the move ment of said rod when the lamp is moved in the. ordinary manner, substantially as described.

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

THOMAS SAMUEL TARLING.
