IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 169,916, dated November 16, 1875; application tiled April 8, 1875.

To cli whom 'it may concer-n:

Be it known that I, RUFUS NUT'IING, of

IVheaton, Du Page county, Illinois, have in-V vented an Improvement in Lanterns, of which the following is a speciiication:

rIhe object of my invention is a lantern for coaloil and candles operating equal to the best, cheaper, more transportable, and adapted to more uses; and relates to a fount detachable for house use, and other parts above and below the protector, detachable,to pack Within it for transportation. Air isadmitted through orih'ces covered by automatic dampers below and orifices in the bottom, near the flame, and, being warmed, rises into a vertical chamber over the tlanie. A part escapes at the top, and the rest descends through condensing-passagcs to the Haine. A concave canopy, open top, and automatic cowl, to secure ventilation and draft, and a spring' connected with the handle to preventjerirs upon the llame.

Figure l is a transverse view, as if divided vertically in the center, between the doors, from a to .r in Fig. 2, which is a vertical view of a horizontal transverse section from w to .c in Fig. 1; Fig. 5, sectional. view of the bottom of the door and part of protectorbottom.

The pedestal B, made oi' wire, as showmfor close packing, is in two sections, detachably united, and held to the fount by the screw (J, attached to the fonct-bottom, which is also to connect the fount with my oil-can stand, (Patent No. 152,001) for the convenience ol" students and others who wish to use one fount for both lamp and lantern, the pedestal and protector being removed i'orsuch use. The bracechamber H stiliens the connection of the protector' with the fonnt,and, being perforated, and having attached to it dampers Hx, operating like my Patent No. 148,842, but poised by the inside half, serves for a wind-break to guard the dame, and is detachable when the fount is used separately. The protector-bottom I is concave for increased stiffness, and perforated to admit air to the flame, and to its center is attached a screw, IX, to detach-ably connect it with the burner, that the burner and fount may be otherwise used when candles are used in the protector, which resembles my Patent No. 148,842; but inst-cad of the two central vertical strips T and S is the single strip K, swaged to the form ot T and S, but lnuch iirmer and cheaper made, and attached to the guards kx, hinged to the studs l?. 'Ihe strips L are the same as one-halt' of' the strips K, except being laterally extended and curved to deflect air leaking in between them and the door-studs from the flame, and the heat of the llame from the tubes P, which also answer for Studs, to which the doors are hung. A semicircular plate, M, is attached to the lower end of strips I( and L, for the panels Ix to rest on and t'or a wind-break, the bead in its edge breaking the wind going between it and the panels, (which may be of plane or curved giass or mica,) aud also between it and the protcctordiottom, as shown at Fie'. 5. The canopy 0, for concentrating the noxious gases hot from the outside of the flame, and other air, to the chamber V, is connected to the bot tom I by the studs I), and to it is detachably connected the chamber V, bisected by tube 3, whose under side is open within it, whence the central and coolest part of the ascending air, with the pure air from the orifices in the bottom l, passes into and through the tube 3, pas sages S and P, and chamber U, attached to the bottom I, to the flame, while the outer part, too hot to readily descend, having little llame food, and constantly tending to the highest point, chiefly escapes through the cowl W, passing by the closed sides ofthe square tube 3 within the chamber V. The passages S are detachable, for packing and cheapness, and oi paper, or other like non-conducting material, instead of metal, to increase the gravity oi' the descending air within them by cooling, and for lightness and less cost. To secure constant draft in strong winds is the cowl W, having the parallel wings Y attached to the horizontal plate X, turning upon the pivot Z in the bracket 2, attached to the chamber V, and poised by the Weight I, or any more desirable way. The spring 2 around the chrlnher V holds the weight of the lantern upon the handie 4, to prevent sudden jerks from balking the thune, and the joints o' allow the handle to be folded for packing, being detachable with the chamber V, held to the canopy 0 by the pin 0x or a screw.

My device di'ers essentially in operation from my Patent 148,342, and other closed-top lanterns, in that they require a wide open space at the top of the protector for the entire het gases from the outside of the tiame to escape, the central and cooler part going around to the flame the second time, which open space, unless provided with regulators, admits strong winds to injure the flame, while in this lantern these gases can escape through the open top, protected by the cowl, through which no winds can enter, and the protector can extend so near to the canopy that winds do not attect the flame.

While this lantern operates well with ordinary fiat-wick burners, itis especially designed formynochimneydivided-flameburner,with ame-coverts, and having a screw attached to its upper side for ready connection for burning coal-oils, aml, with the wick-tubes shortened, sperm or lard oil, or candles, by having a candle-socket provided with a burner-screw, leaving the automatic fount free for domestic use. A spring-catch optionally connects the burner and t'ount.

A globe or chimney may be used instead of the tlame glass protector, it' preferred.

For a cheaper lantern, yet superior to ordinary coal-oil lanterns, the tubes 3, passages S, chamber U, and dainpers H may be omitted, and the chamber V made smaller and shorter.

I claim as my invention- 1. The lantern-pedestal B, in sections, de tachably joined together, in combination with the fount, substantially as and for the objects described.

2. The detachable brace-chamber H, in combination with a lantern-fomit and protectorbottom, as described.
