MINERS LAMP.

SPECIFICATION forming part of Letters Patent No. 478,487, dated July 5, 1892. Application filed June 23, 1891. Serial No. 397,197. (No model.)

To all whom it may concern.-

Be it known that I, JULIUS R. WATTS, of Springfield, in the county of Sangamon and State of Illinois,have invented a new and useful Improvement in Miners Lamps, of which the following is a full, clear, and exact description.

My invention relates to an improvement in miners lamps, especially to that class of lamps known as pit-lamps, and has for its object to produce a lamp of simple, durable, and economic construction, and to providea means whereby a miner without removing the lamp from its support may expeditiously and conveniently raise and lower the wick, and thus increase or diminish the power of the light.

The invention consists in the novel construction and combination of the severalparts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improved lamp, the spout thereof being in section; and Figs. 2 and 3 are perspective views of details in the construction of the lamp.

The lamp-body 10 may be of any approved shape or construction. The spout 11 is located at an acute angle to the body and is preferably maintained in this position by essentially-wedge-shaped plates l2,which plates serve as attaching mediums. The upper end of the s; out (indicated by the reference-letter a) continues of the same diameter, or practically so, until at a point a some distance below the upper end, where said spoutincreases in diameter and tapers, gradually widening until it reaches the wedge-plates 12. Thus the lower portion of the spout is given practically a conical contour. Within the spout an essential conical sleeve 13 is held to slide, which sleeve is open at both ends, and at its upper end is provided with a series of teeth 14. The sleeve has attached thereto at its outer side a rod 15, which rod extends outward through the slot 16 in the spout and downward to a point near the bottom of the spout, at which point it is provided with an attached handle 17, preferably at an angle to the rod. In order that the oil may not spill in quantities, and to prevent the entrance of dirt and dust through the slot 16 in the spout, a housing 18 is secured around the slot, said housing having an opening therein for the passage of the rod 15.

In conjunction with the spout a wick-retaining device A is employed. This device consists, preferably, of a skeleton body 19, having an oval shape. and a curved shank 20 integral with the upper end of the body, which shank terminates in prongs 21. The lower end of the body of the wick-retaining device has attached thereto a handle 22, preferably located at a right angle to the body, as shown in Fig. 2.

The spout of the lamp passes through the body 19 of the wick-retaining device, and the body is sufficiently large to permit of its having vertical play around the spout. The shank-section of the device is curved from the body of the lamp in the direction of the spout in a manner enabling the prongs 21, when the device is uplifted, to be forced over the upper end of the spout.

The shank of the wick-retaining device is guided in its movement through the medium of a plate 23, which is secured to the front upper portion of the lamp-body and to the spout, the said plate being made to terminate at its outer end in a fork 24, through which the shank of the wick-retaining device passes.

In operation the Wick is passed through the sleeve 13, and the teeth 14 of the sleeve hold the wickin engagement therewith. When it is desired to raise the wick, the rod 15, connected with the sleeve, is pushed upward, carrying the sleeve with it, and when the wick appears at the top of the spout the retaining device A is pushed upward, which causes the prongs thereof to enter the'wick and hold it in its lifted position. If the wick is to be further raised, it being held by the prongs of the retaining device, the sleeve is drawn downward, enabling it to obtain a hold lower down upon the wick, the wick-retaining device is released from the wick and the sleeve is carried upward until a sufficient portion of the wick has been carried out of the spout, whereupon the retaining device is again engaged with the Wick. It is evident that by the use of this device the wick may be lowered as readily as raised.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the lamp having a spout provided with a wick-raiser, of a guide between the spout and the body of the lamp, and a wick-retaining device having an opening at its lower end freely embracing the spout and the base thereof and extending upward and outward therefrom through the guide to the upper edge of the spout, substantially as set forth.

- 2. In a miners lamp, the combination, with the'spout thereof, a sleeve held. to slide in the direction of the spout and is provided with prongs projecting adjacent to the upper end of the spout and dapted to cross the same and enter the wick, and a forked guide through which the upper part of the curved retaining 7 device passes, as and for the purpose specified.
