' Specification formingpart of Letters Patent No. 177,824., dated May 23,1876; application filed April 25, 1876.
To all whom it may concern.- p
Be it known that I, LEANDER E. FISH, of v Washington city, District of .Golumbia,have
invented. a new and Improved Hot-Air Globeand Shade Holder, for Gas-Burners; and'I do hereby declare that the following is a full,
- clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which the figure is 'a side elevation, with the hot air globeholding devices in section, and the telescopic shade-holder tubes broken away.
My invention is designed to impart steadiness to the flame of Argand gas-burners, which are used with a cylindrical chimney, and more particularly to those burners which are exposed to drafts of air, as street-lamps and other out-door lights.
My invention consists in the application of an outer globe or cylindrical chimney to the chimney proper, which outer globe is drawn inwardly at the bottom, and terminates in a horizontal edge ground-smoothly, and adapted to be clamped by the holding devices and firmly held against displacement. This-said globe forms a closed hot-air chamber around the chimney proper, so. that the air whichfeeds the flame is compelled to pass down the 1 holding devices, as hereinafter more fully described.
Inthe drawing, A represents an Argand gas-burner of the ordinary construction, which is to be screwed upon the supporting-stem O of a stand, and carries the usual narrow cylindrical glass chimneyB. Between the burner A and the stem 0 I interpose a disk, D, having a screw-threaded portion, a, and upon this screw-threaded portion Iarrange' an annular clamping-nut, E, between which disk D and nut E the inwardly-drawn lower edge of The invention also further consists in the hot-air globe F is clamped and held, the said horizontal lower edgebeing ground smoothly, so as to fit nicely the clamping devices'aud form an air-tight joint. The outer globe'is thus completely closed at the bottom,
and the only passage for the air to the burner is down the annular space betweenthe globe and the chimney. The important advantages arising out of this arrangement are, first, that the air is heated before it is fed to the flame, which produces a much better light; and, second1y,'the flame is completely protected from the wind, so that it may be used to great advantage for street-lamps and other out-door lights. The outer globe not only protects the flame by warding off the wind, but involves another principle, which produces important results. It will be seen that as the air enters the annular space it is compelled to pass downwardly to the fla1ne,while the air that leaves the flame passes up the central chin1-- ney. The air in the annular space, however, in passing down becomes heated, and, follow ing the laws of convection, would have a tendency to rise, but for the fact that it is positively drawn down by the rising current in p the central chimney. The air is then fed to the burner under a traction in opposite directions, which greatly assists in steadying the.
same, and hence diminishes the influence of the wind upon the flame.
In constructing the outer globe I do not confine myself to any particular form, and may make it either cylindrical, as shown, or of a globular form, and the same may be made either transparent, opaque, or eolored,.. according to the character of the light required.
In making use of my improvement it will be necessary to have a specially-constructed shade-holder, and for this purpose I construct the nut E with screw-sockets, and screw into the same telescopic arms, which consist of curved tubes b and sliding spring-arms 0,-having. hooked ends, to receive the lower edge of the shade. These tubes b are curved upwardly for two reasons, one off which is to bring the a shade up to its .proper position, and thus compensate for the lower attachment of the telescoped arms, which my devices necessitate, and the other is to produce a frictional contact with the spring-arms a, so as to hold them fixedly in any extended position, the said arms being made of straight; spring-Wire before being placed in the tubes.
I am aware of the fact that gas-globes have been constructed with inwardly-drawn horizontal edges, unground, and for use only as a chimney or globe, with an open bottom, and that a straight outer chimney has been employed to produce a hot-air chamber by having its lower end loosely supported upon and t closed by a subjacent disk attached to the burner; and I therefore claim'sai'd globe only when constructed with horizontal inwardly-- drawn edges, ground, and adapted to be clamped, as described, with an air-tight connection. I do not claim, fnrthermoreyanex-i tension shade-holder, as this is not broadly new, but confine my invention to the curved tubes, with spring-extensions. v
Having thus described my invention, what; I claim as new is- 1. A hot-airglob'e, F-,*for a gas-burner, having horizontal inwardly-drawn lower edges, ground smoothly, and adapted to he clamped with an air-tight connection a't'theb'ase, substantially as and for the purpose described.
2. A hot-air globe for a gas-burner, having horizontal inwardlydrawn lower edges, in combination with a clamping device, adapted to hold the same with an air-tight connection, substantially as and for the purpose described.
3. The combination, with the globe F, of
the-ciamping-nut E, and thedisk D, having screw-threaded portion a, substantially as and for the purpose-described 4. The clamping-nut E,havingscrew-threaded sockets, in combination with the curved telescopic shade-holder be, substantially as and for the purpose described;
55 The telescopic shade-holder'consistin g of the combination of the curved tube b, and the straight extensible spring-arms c, sliding therein, and vprovided 'wi th' h'ooked extremities-'for'holdingthe shade, snbsta'nti-all5' as described; I p
The above spee'ifieaition ofmy invention signed by me this 22d day of 7 April, 1876.
