IMPROVEMENT IN OF KEOKUK, IOWTA.l

LAMP-BURNERS.

Specification forming part of Letters Patent No. 58,893, dated October 16, 1865.

To all whom t may concern:

Be it known that I, JOHN F. SANFORD, of Keokuk, in the county of Lee and State of Iowa, have. invented certain new and useful Improvements in Lamp-Burners; and I do hereby declare that the following is a full, clear, and exact description thereof, ret'erence being' had to the accompanying drawings, making a part of this specification, in which- Figure l is a side elevation of the improved lamp-burner. Fig. 2' is a side view ofthe burner, showing the adjusting spur-wheel for moving the wick. Fig. 3 is a diametrical section of the burner. Figs. 4 and 5 are devices for adjusting the spur-wheels up to the wick.

Similar letters of reference indicate corresponding parts in the several gures.

This invention relates to improvements on lamp-burners which are adapted for lamps `that burn the hydrocarbonuids, and which are provided with rotary spur-wheels for adjusting the wicks in their tubes.

This class of lamp-burners is frequently reudercd worthless by the wearing out of the spurs upon the wheels which are used for adjusting the wicks. Vhen the points of these spurs become dull, which they soonA do, the wicks cannot be adjusted; and as these spurs are applied permanently within the cage of the burner, they cannot be readily removed therefrom; hence theimporlance of providing some means whereby the spurs can be sharpened in the burners and also adjusted up to the wick in case they lail to act regularly upon it.

The nature-of lny invention consists in providing for the application of a file to thespurs of lamp-burners for tiling these spurs sharp when they become dull 5 also in providing for setting up said spurs as near as desirable to the wicks in tubes of lamp-burners, so that the spurs can be made to act regularly uponthe wicks for raising and lowering them, as will be hereinafter described.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying drawings, A representsthe cageor body of the burner. Bis the cone thereof, and C is the wick-tube, within which the wick is moved up and down by means of spur-wheels et a, that are appliedV to arod7 b, as shown in Figs. l, 2, and 3. These parts may be made in the usual well-known manner. The rod b, by which the spurs a c are adjusted, passes through the cage of the burner, and has its end bearing in a springplate, Cf, which is secured permanently at its' lower end to the wick-tube C, its upper end being free from this tube, as shown in Fig. 3.

The spring-plate G 1s slotted to allow the wheels a a to work freely, and the wick-tube C is also slotted to allow of the entrance of the circumference of the said wheels, so that the teeth on the latter may act upon the wick. The opening' through the. cage A for the rod b is made suiiciently large to admit of the wheels a a being adjusted up to the wick when desired. This adjustment of the spur-wheels will be hereinafter described.

On each side of the two spur-wheels a c, I make openings g g through the perforated cage A, of sufficient size to admit through them aiile, G, (shown in red lines,) which is used for the purpose of sharpening the teeth or spurs on the wheels a a. Said openings are arranged directly opposite each other and in a line with the spur-wheels, so that the file can move freely through the cage during the act ot' sharpening the teeth.

As the spur-wheels are worn away by c011 tinued sharpening and use, it is found necessary to provide some means foradjustingthese spurs up to the wick, so that they will always take hold of it. This device consists in ap plying a yoke, h, around t-he tube C and securing it to the upper end of the spring-plate C', as shown in Figs. 3 and 5. The yoke has a screw, i, tapped through it, one end of which l abuts against the tube C, so that by adjusting this screw the upper end of the plate C', to-v gether with the spur-wheels a a, can be drawn up 5 or, if desirable, a wedge, j, maybe used in conjunction with the yoke h instead of the set-screw for moving the spurs up to the wick.

I do not desire to confine myself to the use of the devices herein described for adjusting the bearing-plate G' of the spur-wheels c c, as other contrivances may be adopted for effecting this object. I prefer, however, to adopt the plan shown in Figs. 3 and 5.

The openings g g through the cage A of the 2 :isses burner will admit of the lighting of the lamp without removing the chimney, by inserting al burning match or taper through said openings and moving it upward so as to bring the flame in Contact with the upper end of the wich-tube.

It' desirable, small sliding or hinged gates may be applied to the burner or cage A for closing the openings g g and g' when they are not required open.

I am aware that lampburners have been so constructed as to admit of the lamp being lighted through apertures in the cage or body of the burner.

I am also aware that other lamp-burners have been so constructed that the spurs on the wheels which move the wiel; may be sharpened through apertures in 'the cage ot' the burners.

I am further aware that lamp-burners have been so constructed that by means of a screw and spring the wicks may be pressed more or -less forcibly in the direction ot' the spur-wheel to regulate the iow of oil. i

None of these things, therefore, do I el aim, broadly, in and of themselves; but

What I do claim, and desire to secure by Letters Patent, is-

In a lamp-burner, such aconstruetion and arrangement of parts that while they admit of the sharpening ot' the spurs of the wheels which move the wicks, will also permit the lighting of the lamps through apertures in the cage of the burners without the necessity ot' cont-rivances for depressing the wicks for that purpose, substantially as above described.

2. In combination with apertures through the cage of a lamp-burner so constructed and arranged as to admit the sharpening ot' the spurs upon the wheels which move the wick without moving or displacing any of the parts, a contrivanee for causing these spur-wheels to engage with the wick, substantially as and for the purpose above described.
