LANTERN.

SPECIFICATION forming part of Letters Patent No. 244,670, dated July 19, 1881. Application tiled May 21, 1881. (No model.)

To all whom it may concern:

Be it known that I, ELIAS B. BEQUA, acitizen of the United States, residing at Jersey City, in the county of Hudson and State ofN ew Jersey, have invented new and useful Improvements in Lanterns, of which the following is a specification.

This invention relates to certain improvements in lamps and lanterns; and it consists in a peculiar construction, arrangement, and combination of parts, whereby the flame is su pplied with a uniform quantity of air without being affected by excessive drafts induced by sudden or rapid movementsl of the lantern, the excess ot' air above that required for proper combustion being removed through suitable lues, so as to cool the lamp-frame and decrease the danger of explosions, and a free escape for the products of combustion being also provided through. a perforated dome attached to a cap-piece, which is secured by an attachment and catch of novel construction, as hereinafter more fully set forth.

In the accompanying drawings, which fully illustrate the invention, Figure l is a vertical section. Fig. 2 is a bottom view. Fig. 3 is a view of the lamp fount and burner, partly broken away to showthe -relation of the parts. Fig. 4 is a view ofthe hanged wick-tube. Fig. 5 shows longitudinal and transverse sections through the burner-cone. Fig. 6 is a horizontal section through domed cap-piece. Fig. 7 is a view of the hinge attachment of the cappiece; and Fig. Sis a View of the hasp and spring-catch by which the cap-piece is secured to the frame.

A indicates the base of the lantern, which is concavo-convex in form and provided near its upper edge with perforations a et, that are arranged for the passage of air tothe space below the fount when the' lantern is resting upon a table or other support.

Above the base A is the lantern-body B, within which is arranged the oil-fount C. Through the oil-fount pass tubes D D, which terminate below the body of the lantern in a cavity, formed by the,

perforated cup-shaped foraminous plate or plates d, that receives and transmits air to and through the tubesD for the purpose of supplyingthe requisite inside draft to the burner. The upper projecting ends of the tubes D receive the short tubes e e on the under surface of the pyramidal burnercone E, the inner surface of which is nearly conical in form. This burner-cone consists of an inner and outer shell, which are perforated y at thel top by the elongated iiame-slot c. The lower portion of the outer shell is cut-away on each side, so as to present an opening, e?, having Aan upper curved outline, as shown, and 6o 'leadin g directly to the space between the shells.

The short tubes c e, which-communicate with the main draft-tubes D D, also pass between the inner and outer shells of the burner-cone at each end. Within these short tubes are arranged the perforated cones e363, which point upward and serve to check or regulate the force of the draft.

In the inner shell of the burner-cone, above the upper end of the tubes c, are the :forami- 7o nous plates c4, that serve a similar purpose in checking the pressure of air 5 and in the outer shell, opposite these plates, are perforations e5, that permit the escape of any undue excess of air, thus insuring the requisite amount of draft without the objectionable eects of an excessive pressure. The lower portion of the burner cone is provided with a iiange, c, that nearly covers the cup-like depression at the top of the oil-fount. This depression is formed 8o by an upwardlyprojecting band, B', which is closely perforated for the passage of air' to the burner and interior of the globe, forming an outer draft, the force of which, however, is broken by the projecting flange c6, that acts as a guard -to prevent too great a pressure.

Attached to the body of the lamp B, at its upper part, is a daring concavo-convex ange or band, B2, that is provided with perforations b b, for the passage of air to the vertical perfo- 9o rated band B', air being also permitted to enter 4at the annular opening between the upper edge of the band B? and a similar band, B3, that is supported -upon the upper edge of the vertical band B. The band B3 forms the lower portion of the chambered globe-holder. When the lamp is exposed to wet weather the perforations b b also permit the escape of water that might otherwise collect on the concave surface ofthe band B2.

Within the socket c of the oil-fount is iitted the wick-tube F,- which is provided with the provided with a hasp,

4 where it may be fastened by the ternal blows or injury.

usual stem and ratchets,f, for raising and 10W- ering the wick. At the top of' thenpper fiattened portion of this tube is a curved flange, f', the Haring ends of which, when the burner is in position, itclosely against the upper edges of the inner shell of the latter, thus holding thewi'clr-tube in proper line with the flame-slot and preventing the currents of air passing through the burner from striking the edges ot' the flame.

Attached to one side of the coneavo-convex band B2, by means of a suitable hinge, b', is a convex annulus or band, B4, having a central opening that receives a ange or rim on the lower end of the glass globe G, within which projects the upper end of the burner-cone E. The annulus B4 also supports the upper frame of the lantern surrounding the globe, and is b2, that is perforated at its end and enters a slot, b3, in the band B2, hook b4, or a suitable padlock, if desired, so as to securely lock the lantern when necessary. When the upper frame ot' the lantern is closed the convex an'nulus B4 forming a chambered globe holder, within which is the flange or rim at the lower end of the globe.

Extending upward from the annulus B4 vare the ilues H, which are preferably three in number and support an attached cap-piece, I,that is surmounted by a perforated dome, K. The flues H are connected by the wire guards or ribs h h, which are threaded through the flues and suitably secured within the same, so as to form a continuous frame around the lantern for the protection of the glass globe from ex- At 'the top of the ues H, on their inner sides, are perforations h' h for the passage of air, the lues thus serving to admit a moderate'downward draft to thechambered globe-holder when the lantern is at rest; but are principally useful by furnishing a ready escape for an excessive pressure or draft of air when the lantern is rapidly lowered or in high winds. The ues are connected at their upper ends by an annular band or rib, h2, `to which is attached the cap-piece I by means of a stout wire, t', thatis bent twice at right angles and securely attached to the band h2, after passing through suitable perforations t" t" in the edge of the cap-4 piece I. If desired, the relative position of this wire attachment may be changed by attaching it directlyt r: En? cap-piece and forming the perforations i i n the band h2. This device forms a simple, inexpensive substitute for a hinge that is not liable to get out of order, and allows a perfect freedom of motion to the cappiece when it is desired to open the lantern for introducing or removing the globe. It also en,- ables the cap-pieeeto fit more closely upon the frame.

The cap piece I is provided with a springhasp, I', that engages with a spring-staple,12, which is attached at its upper end to the outer side of one of the iiues H, the lower end of the rests on the concave flange B3, thus staple being bent inward at a right angle to enter a small slot in the flue, and -then again bent in an upward direction to form a stop thatlimits its outward spring. When the hasp I is, engaged with the spring-staple I2 the cappiece is held rmlyin place, but may befurther secured, if desired, by means of a small padlock attached to the staple on the outer side of the hasp. When it is desired to release the hasp for the purpose of raising the cap-piece, a slight inward pressure upon the staple will be sufficient to disengage the parts.

The upper end of the globe Gr, when in position, presses against a horizontal annular flange, 7c, in the interior of the perforated dome K, and is thusheld firmlyin place. This dome is provided with the usual perforations 7c 7c', for the passage of heated air, and also has a bail, L, by means of which the lantern is handled.

From the foregoing description the operation and advantages of my improved lantern' and globe will be readily understood.

The draft passing upward from the base of' the lamp through the tubes on each side of the oil-fount to the burner and globe is checked and rendered even and steady by means of the perforated plates'at the lower ends of the main tubes and by the perforated cones in the small connecting-tubes and foraminous plates above the latter on the inner shell of the burner-cone. By means of the vertical perforated band that connects the top of the oil-fount with the chambered globe-holder the interior of the burner and globe is 'still further supplied with fresh air in a inely-diftused state, the pressure being moderated by the perforations through which it is made to pass, and an exit for any excess being afforded through the flues that lead up on the outer 4side of the globe to the cap piece supporting the perforated dome,

through which the heated air and products of' combustion finally escape.

The peculiar construction of the burner is IOO IIO

such that it is enabled in a still atmosphere to burn oils having a test of 150o without the necessity of using a globe or chimney of any kind, giving a clear, safe light, and in using oils having a test no higher than 150O any globe that will fit the lantern may be used with the burner as a protection to; the flame in the open air.- When using mineral, sperm, or oil of 3000 test a globe is needed that will concentrate the inflowing air in the immediate vicinity of the flame.

E 1h, peculiar construction of my improved globe above described is such that by means of its base flaring outward from the contracted portion or neck g, and adapted to lit over the burner and correspond with the perforated band below the chambered globe-holder, a

draft-current of uniform strength is at all by the ilues and construction of the burner and Wick-tube, so that the flame is prevented from dipping or being extinguished, the edges of the llame being protected especially by the peculiar flange at the top of the Wick-tube, which corresponds closely with the flame-slot in the apex of the burner-cone.

It will be understood that I do not confine myself to the precise details of construction herein described, as the parts may be combined in anumber of Ways and still kept within the limits of the invention.

What I claim is- 1. The combination, with a lantern frame and fount having air tubes or passages covered at their lower ends by foraminous plates, and a Wick-tube provided at its upper end with a curved dan ge, of a burner-cone consisting of an inner and outer shell having a flame-slot that corresponds with the ange of the Wick-v tube, and provided With the described openings and tubes having perforated cones adapted to moderate thc draft, substantially as described. l

2. The combination, with an oil fount and burner, of a chambered globe-holder and ilues leading therefrom on the outer side of the globe, to afford a means of escape for an excess of air, and thereby/preventing the flame from dippi g or being extinguished or the parts unduly heated, substantially as set forth.

3. The combination, with a lamp fount, burner, and ehambered globe-holder having iiues leading therefrom, of a globe having a flaring base and contracted neck, whereby it is adapted to concentrate the draft in the vicinity of the llame Without becoming excessively heated, substantially as described.

4. The combination, with the lamp body and globe, of a hinged frame composed of the npper convex band ofthe globe-holder, fines leading therefrom and supporting an attached cappiece, and circular guardsor ribs connecting said dues and adapted to protect the globe from external injury, substantially as specified.

5. The combination, with the cap-piece and upper rib of a lantern-frame, of an attachment' composed of a wire bent twice at right angles and adapted to support said cap piece when raised or thrown back, substantially as set forth.

In testimony whereof I have hereunto set my handin'the presence of two subscribing Witnesses. e
