ALVIN'V TAPLIN, OF SOMERVILLE, MASSACHUSETTS;

I Letters Patent No. 87,988, dated Ma/reh. 16, 1869.

IMPROVEMENT IN LAMP-BURNERS.

The Schedule referred to in these Letters Patent and making part of the lame- To all persons to whom these presents may come Beit known that I, ALVIN TAPLIN, of Somerville, in the county of- Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Lamps for Burning Liquid Hydrocarbons; and I do hereby declare the same to be fully described in the following specification, and vrepresented inthe accompanying drawings, of which- Figure l denotes a top view,

Figure 2, a side elevation, and

Figure 3, a transverse section of a lamp-burner provided with rny invention. l

'lhe said improvement has reference to the means of supporting the glass chimney, and supplying air to that part of the iame of the wick which usually extends above the air-deflector, or cone.

In the drawingsv v Ais the foraminous base, on which the lower edge of the chimney usually rests i B is the wick-tube; and

O, the cone, or air-deiiector.

This latter I construct with a ange, or lip, a, and a series of air-holes, b l), dic., arranged concentrically about the slotted dome c. v

The flange, or lip is to project down from the periphery of the deficctor.

The said deector is supported above the base A byV a series of arms, or posts, d d (Z d, extended upward from thev said base, and fastened to the dedector, or extended from springs e e e, in manner as represented.

To each of the said arms the lower part of a leafspring, e, riveted.

The upper end of this spring is surmounted by one of a series of arcal bearers, f f f f, which are arranged relatively to the outer edge of the deeetor, in manner as represented;

Each of the bearers is provided with alip, or flange, g, which projectsvupward from it, andbears against the ange of the deector.

The next adjacent ends of the bearers are very near together, their distance apart being, generally speaking, just about sufficient to allow of the necessary play or movements ofthe bearers.

When the chimney is pressed down upon, and so as to force its lower 'edge against the bearers, they will move inward, and allow it to pass down by them, and to the base A; and while the chimney may be on such base, the bearers, by the pressure of their springs, will be forced against the inner surface of the chimney, and vill thus aid in keeping the chimney steady on the While the burner'may be in operation air will pass through the series of holes, b.

For steadying the chimney, and supplying it with air from the space beneath the deflector, it has been customary `t'iiform-the deiiector of thinmetal and of a concave-convex shape-,fand with radial slits extending from-.its periphery.'

It has been customary to surround the deector with a helical spring, coiled into a series of holes made in the deector, near its outer edge, such being as represented in the United States patent, No. 73,488. A v

` lhe contraction of the helical spring, or the peripheral springs, (formed by the radial slits,) by a close-fitting chimney, tends to diminish the passages for the supply of air to the space over the deflector,and it has been found, that as glass chimneys vary more or less in size, contractions of the air-ducts by a closely-{itting chimney, frequently, very materially, by the resulting diminution of the supply of air, e'ect the combustion ofthe iiuid of the wick.

Consequently I have preferred to maintain the airducts, or passages through the deector at a constant size, and to apply to the deiiector such bearers as will act independently of the air-inlets, that is, such, as when contracted, will not effect any diminution of the air-passages of the deector. f I would also remark, that for supporting a chimney, when reposing on a circular foraminous plate, or rest, and encompassing an air-deflector, it has been customary to employ a series of curved springs, either extended upward from the said rest, or downward from the deector, such being as represented in the United States patents, Nos. 75,565, 75,566, and 80,909. v `In carrying out my invention, I employ with each of such springs, when projecting upward from the Ychimney-rest, or a post, or standard, elevated thereon, and serving to support the air-delector, an arcal bearer, as set forth, having its upper surface camshaped, or so inclined, that when the chimney is pressed down upon it, such inclined surface will cause the arcal bearer to move inward, in order to enable the chimney to pass the outer edge of the bearer.

Each bearer extends horizontally in opposite directions from its supporting spring, and at their ends the bearers of the series are very close together, as hereinbefore stated.

The cireumscribing ange, or lip a of the air-de-` flector serves, with the anges, or lips g of the bearers,

to arrest the bearers under the outward pressure of l springs of the bearers.

I make no claim to either of the lamp-burners described in the aforesaid patents; nor do I claim any parts, combination, or arrangement of parts, contained in either of such burners, as neither of them contains a series of arcal bearers, constructed and arranged with an elevated foraminous air-dedector, and with springs, and a chimney-rest, and provided with stops, as in the burner represented in the accompanying drawings, and hereiubefore explained.

In this bearer the circumferential air-passages of the elevated foramnous deleotor O, and the series of the deleetor maintain a uniform size, however the springs c, arranged and combined with the chimneychimney may vary in diameter, the areal bearers servrest, as described. ing not only to support the chimney, but to arrest; the passage of most, if not all, of lshe air up by the eireu1nference of the deiieetor, i

I claim the arrangement of the series of inclined top areal bearers f and the stop-projections :L g with ALVIN TAPLIN. Witnesses: R. H. EDDY,
