MANTLE-S U PPO RT.

SIPECIFIGATION forming part of Letters Patent No. 681 ,265, dated August 27, 1901. Application filed February 28, 1901. Serial No- 49,324. (No model.)

ToaZZ whom it may concern:

Be it known that I, THOMAS RODERICK, a citizen of the United States, residing at C0- lumbus, in the countyof Franklin and State of Ohio, have invented certain new and useful Improvements in Mantle-Supports; and I do hereby declare the following to be a full, clear, and exact description of the in vent-ion, such as will enable others skilled in the artto which it appertains to make and use the same.

My invention relates more particularly to supports for gas-mantles that are adjustable vertically.

The object of the invention is to provide a simple and economically-constructed device that can be quickly adjusted without endangering the integrity of the mantle.

My invention consists, essentially, of a gasburner provided with a vertically and directly movable mantle-support located centrally in the burner-tube, combined with a spring to frictionally hold said rod in any position to which it is adjusted, the rod being directly movable to efiect the adjustment.

I am aware that it has been proposed to 10- eats a mantle-support%ng rod centrally with respect to the axis 0 the burner-tube and that it has been proposed to adjust such a rod vertically by means of screw-threads on the rod engaging a nut in the burner. Hence I do not claim, broadly, a centrally-located and vertically-ad j ustable mantle-supporting rod.

. In the accompanyingdrawings, in which I have illustrated an embodiment of my in vention, Figure 1 is an elevation, partially in section, of a burner equipped with my mantle-support. the support removed from the burner.

1 designates the mantle-supporting rod or standard. I

2 designates a spring attached to the lower end of the rod. In the form shown the spring 2 is made in one piece with an inwardly and radially extending tongue 2, to'which the lower end of the support is riveted or otherwise secured. The upper end of the rod is furnished with a suitable hook or catch 3, on which the mantle is suspended. This hook or catch 3 is shown to be made frictionally attached, but removable, so that when removed the upper end of the rod can be passed through a central opening in the gauze tip 5.

Fig. 2 is a perspective view of.

The spring 2 is made so that it must be slightly compressed to be inserted into the burnertube 4, and when so inserted this spring frictionally engages the inner sides of the burner-tube. Bytaking the upper or hook end of the supporting-rod between the fingers the rod can be adjusted up or down, the rod remaining at the place to which it is adjusted by virtue of the frictional engagement of the spring 2 with the inner sides of the burnertube 4. As mantles are lightin weight,very slight friction suffices to hold the supportingrod in place.

Many of the mantle'supports now on the market are secured on the outer side of the bnrner tube. In such cases thesupport is likely to warp or bend, thus throwing the mantle out of the vertical, thereby endangering theintegrity of the mantle, to say nothing of the effect of this upon the character of the light. IVith my invention the mantlesupport stands centrally within the mantle and there is less likelihood of any bending of the rod, because the weight of the mantle is supported along the entire axis of the rod and the heat is equal on all sides of the rod. The rods themselves can, however, be made of some refractory material, so that bending of the rod shall be impossible.

I do not wish it to be understood that I confine myself to the particular form shown in mydrawings herewith, because the gist of the invention resides in the mantle-supporting rod with a spring to frictionally engage the interior side of a burner-tube, and it is quite obvious that this idea can be embodied in a multiplicity of forms.

What I claim, and desire to secure by Let ters Patent, is

1. In a gas-burner, a mantle-support comprising a rod constructed at its upper end to support a mantle, a spring attached to said rod to slidably bear against the inner side of the burner-tube, whereby the rod is adjustable vertically with a direct movement thereof, and is held in adjusted position in said tube, substantially as described.

2. A mantle-support for a gas-burner comprising in combination, a rod, a spring 2 of cylindric form having an inwardly .and radially extending tongue 2 to which the rod is attached, said spring 2 adapted to slidably bear upon the inner side of the burner-tube whereby the rod is adjustable vertically with a direct movement thereof, and is held in adj usted position in said tube, substantially as described.

3. In a gas-burner, a vertically-adjustable mantle support located centrally in the burner-tube, said support comprising a rod constructed at its upper end to sustain a mantle, combined with a spring to frictionally hold said rod in any position to which it is adjustable in said burner-tube, the rod being adjustable with a direct vertical movement thereof, substantially as described.

4. In a gas-burner, the combination witha burner-tube, a foraminous tip therefor, 21. cen-.

tral opening for the movement of a mantlesupporting rod in'said tip, a mantle-supporting rod extending through the central opening in the tip, a spring to frictionally hold said rod in any position to which it is adjustable in said burner-tube, substantiallyas described.

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

THOMAS RODERICK.
