FRANK L. FLYNN, OF WILKES-BARRE, PENNSYLVANIA.

MINER/S LAMP.

Application filed April 10, 1911.

To all whom it may concern:

Be it known that I, FRANK L. FLYNN, a citizen of the United States, residing at Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Improvement in Miners Lamps, of which the following is a specification.

This invention relates to an improvement in no-chimney lamps, more particularly to the type of oil-burning lamp adapted to be attached to the cap of a miner.

One object of the invention includes the provision of mechanism whereby the wick may be fed upward as desired without removing the lamp from the cap.

Another object is to provide an adjustable means for varying the intensity of the light independently of the feeding of the wick upward.

Car drivers, from the nature of their work, require a more powerful light than other mineworkers, and it is the practice when such work is undertaken, to feed the wick well out of the burner, and to loosen its fibers by picking,'so that the flow of oil may take place more rapidly and the lamp give a more flaring light. When the lamp has been so adjusted, moreover, it is not easy, in most cases not possible, to restore the wick to its original condition, in order to use the lamp in other kinds of mining work.

Another object is to simplify the construction and arrangement of parts whereby the lamp is easier to operate and is made more durable.

Other objects will appear as set forth in the appended claims and in the preferred form of embodiment disclosed in the accompanying drawings and description.

Referring to the drawings, Figure 1 is a side elevation of my improved lamp; Fig. 2 is a detail of the spout or burner; Fig. 3 is a detail of the wick lifter and compressor; Fig. 4.- is a sectional elevation of the spout and wick-lifter showing the wick under compression; Fig. 5 is a similar view with out the wick; Fig. 6 is a side elevation of the lid and method of its attachment; Fig. 7 is a plan of the lid; Fig. 8 is a cross-section of the spout showing the wick loosely held, and Fig. 9 is a similar view showing the wick compressed.

The spout 12 and lamp body 10 are firmly fastened together by means of a ferrule 11 closely surrounding the base of the spout and provided with integral lugs 13 which Specification of Letters TEatent.

are fastened to the body 10. This improvement obviates the usual knife edge construction in which only the edges of the two parts are in contact and in which the spout is readily broken away. lVithin the spout 12 the member 16 is movable both in a longitudinal and in a transverse direction. For these purposes the lower part of the member or lifter 16 is provided with a slot 17 which is engaged by a pin 18 fastened to the spout, permitting longitudinal movement, and its upper part carries a thumbpiece 15 which is formed with a stem of two dimensions to make a shoulder as shown at 19. The slot 1 L located in the upper part of the spout is slightly larger in width than the diameter of the shoulder 19 so that the stem is freely movable therein.

The wick 25 is held between the wall of the spout and the lifter 16 as shown in Figs. 4, 8 and 9. The elasticity of the wick tends to force the lifter 16 and its thumbpiece 15 outward. To raise the wick, the thumbpiece is left in its outer position and is moved downward to the bottom of the slot 14;. This downward movement does not affect the'wick as the lifter exerts no gripping effect thereon. The thumbpiece is then pressed inward and while the inward pres sure is maintained upon the wick, the thumbpiece is raised to the upper part of the slot, the wick moving upward at the same time to a corresponding degree. If now it be desired to have only a moderate light, the thumbpiece is pressed inward and upward until the shoulder 19 catches under the spout 12 at the upper end of the slot 14 as shown in Fig. 5. The wick is thus held locked in a compressed condition and does not burn so freely. If, on. the other hand, a brighter light is desired, the thumbpiece is moved downward sufliciently for the shoulder 19 to clear the upper end of the slot whereupon the elasticity of the wick will force the lifter or compressor outward and the wick will then burn more freely and rapidly.

It will be noticed that in this construction there is only one movable piece of metal; that the wick can be fed uniform distances at will; that the light may be instantly adjusted to give much or little light as desired; and that all of these manipulations may be erformed by one hand and without removing the lamp from its position on the cap.

As shown in Figs. 6 and 7, the lid is formed of a single piece of metal 20, provided with an integral pintle 21 and a lip 24 opposite thereto. A strap 22 is fastened hinge. The advantages gained by this combination of parts is that the lid is formed of a single piece of metal, while the strap,

being supported at 23, a considerable distanee from the hinge, forms a more or less yielding or resilient support which permits j the use of the cup-shaped lid of great thickness that is commonly in use. Up to this, time the use of lids of such thickness, while highly desirable, was open to the objection Q of requiring .a double hinge to attach them i to the body of the lamp. By my invention, a single hinge is all that is necessary, while i the thick lid is as readily operated as if it were swung on a double hinge.

I claim:

thumbpiece attached to the wick raiser near its upper end and projecting through an aperture in the spout, a shoulder located upon the shank of the thumbpiece and adapted to engage the spout, the said arrangement permit-ting a longitudinal movement to be given to the wick raiser relative to the spout and also permitting a trans verse movement of the wick raiser whereby the wick may be fed upward and if desired clamped in a compressed condition.

2. A no-chimney lamp having a body and spout, adapted to hold a wick passing from the body through the spout and presenting an exposed combustion end, and a device mounted upon the spout adapted to compress the wick or to permit it to expand at a point between the exposed combustion end and the said body whereby the flow of oil through the wick to the combustion end may be restricted, or permitted to flow freely, the said device being also adapted to feed forward the wick as the combustion end is consumed.
