TUBULAR LANTEBN.
SPECIFICATION forming part of Letters Patent No. 269,808, dated December 26, 1885?,
' Application filed September 20, 1882, (No model.)
To all lLo/iom 'it may concern:
Be it known that I, FERDINAND MEYRosn, ot' St. Louis, in the State of Missouri, have invented Improvements in Tubular Lanterns, of' which the following is a specification.
This device relates to that class of'lamps for outside illuminating purposes that are provided with air-tubes` for feeding the flame, and particularly the construction ot'v the air-chamber which surrounds the dome ot' the lantern, and from which the air-tubes are fed with air at their upper ends, and also to the construction ofthe dome. Previous devices have the air-inlets to the annular chambers too much exposed, thereby rendering the light uncertain for outside illuminating purposes when there are extraordinary drafts ot' wind. I have t'ound from experience that devices provided with pert'orations for admission of air are not reliable, and although I am aware that such have been made, yet they do not accomplish the purpose ot' a steady light in a high wind in an exposed position.
The object ot' my invention is to overcome these diiticulties by a more practical construction.
In my present improvement I dispense with pert'orations or air-inlets iu the tloor or top of the chamber, and instead thereof I leave a space beneath the inner wall and extend the floor inwardly, so as to be near to the vertical side ot' the dome, the iioor being formed with radial ribs to prevent the inner wall coming in contact with the Hoor, and thus providing the desired space in an isolated position where the air can reach the entrance to the chamber, while said entrance is well shielded from strong currents of air on the outside ot' the lamp or lantern, especially when the device is, as signaling-lanterns, revolved or swung round. Under and close to the iiange ot' the cap-plate ot" the dome I locate another iiange or collar, which together form a narrow annular opening. The ei'ect ot' this added liange is su'ch'as to prevent the most violent wind from intiuencing the tlame objectionably, as this ilange prevents any upward current of air produced by deiiection from the top ot' the main chamber from entering violently beneath the cap.
in order that the invention may be fully un derstood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure lis a perspective view of my improved annular air-chamber, the dome `having been removed. Fig. 2 is a bottom view there` of', the dome being in position. Fig. 3 is a vertical section on the line 3 3, Fig. 2.
A represents the annular air-chan1ber; B, the air-tubes leading to the burner; U, the hooks by which the handle is attached, and D, the dome of a tubular lantern.
The air-chamber is-t'ormed with a floor plate, a., having inverted lradial grooves c', forming ribs a2, a top plate, I), inclined outwardly and formed on its inneredge with downturned flanges b and recesses or openings b2, the lower edges, b3, of the flanges being inclined, and a vertical ring, c, located midway between the outer and inner edges of the top plate, forming the inner wall of the inner air-chamber, e, and having its lower edge, c', resting on the ribs a2, so as to provide entrances c2 above the tloor'and beneath the ring.A
The dome D is formed of a cylinder, d, titting closely the sides ofthe tlanges band binding tightly ou the upper end ot' the chimney or globe, as usual, and having vertical lips or tongues d', engaging through slits d2 in the capplate E, so as to leave annular openings d3.
I Located beneath the opening Pis a downturned collar, d, conforming to the shape of the outer portion of the cap-plate E.
F are studs on the sides ofthe cylinder, which, being inserted through the recesses or openings (12in the top plate ot'the air-chamber, engage by turning the dome with the inclined edges b3 of the flanges b to hold the domein place.
A space, e, is left between the dome-cylinder and inner edge of the door for the passage of' outer air to the air-chamber e.
In a stationary lamp with an air-chamber made as described the 'wind may come from any direction, and it will always feed the flame with sufiicienttresh air. In usingany air-chamber made oftwo or more sheets ot' metal that are placed close around the globe or dome ot' lantern, even it there be plenty of holes punched in the top or bottom, ifa strong wind is blowing it will certainly smother the flame, as, in-
stead of admitting air into the chamber', take the air out of the lamp and extinguish the flame.
The two flanges-one on the cap-plate and onejust below the cap plate on the cylinderclose to the neck of the dome are a great ad mirage. The top flange is common to all lanterns; but the lower Harige serves to prevent a rising' current of air striking under the upper flange, and thereby disturbing the dra-ft of the lamp and making the llame smoke and go out.
Havingr thus described my invention, the following is what I claim as new therein and desire to secure bv Letters` Patent- 1. The combination of an annular airehamber having inclined top plate, b, liner-plate a., and vertical ring c, and the dome 1),' fitting the it will top plate closely and leaving a space, e, between the door-plate and its cylinder, as set forth.
2. An annular airl chamber, A, formed with floor-plate a, having radial grooves a', forniing ribs a?, a top plate, b, and vertical ring c, located about midway between the outer and inner edges ot' the top plate, forming inner and outer annular air-chambers, e" e', and resting on the ribs ofthe floor-plate, as set forth.
3. The dome D,in combination with the described air-chamber, the dome fitting the top plate closely and leaving a space, e, between the cylinder and tloor-plate, as set forth.
FERDINAND ME YROSE.
