SPECIFICATION forming part of Letters Patent NO. 314,787, dated March 3l, 1885.

Application filed December 6, 1883. @To model.)

To all whom it may concern.-

Be it known that we, JAMES A. BLANKLEY and'GHARLEs H. TALLMAN, of Bellaire, in the county of Belmont and State of Ohiohave invented anew-and useful Improvement in Lanterns; and we do hereby declare that the following is a full and exact description of` the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Our improvements relate to single-globe lanterns for burning coal-oils, and adapted to be used in the open air or in currents of wind, or to be swung or .raised up .and down with vconsiderable violence, without extinguishing the flame, and have for their purpose an increased cheapness and durability of such lanjterns, as well as an increased eflieiency in use.`

Our invention therein consists, principally, in the `novel construction of the in the arrangement of Ethe globe in relation to it, and in the construction of the guard, and in certain operative new combinations of parts, alias more particularly hereinafter specified in the description and in the claims.

For the better comprehension of what follows, reference should be had to the drawings connected with `this specification, in which- Figure 1 is an elevation of our lantern with the hinged portions a little separated; Fig. 2,

' atop perspective view with the globe re moved; Fig. 3, a vertical section through the globe-band; Fig. 4, a plan View of the globeband before stamping; Fig. 5, an enlarged view in perspective of the globe-band as stamped and completed; Fig. 6, an enlarged portion of the guard, showing how the breastwire is secured; Fig. 7, a vertical central section of the lower portion of the lantern, and Fig. 8 a View in detail of the wire-guard frame.

Similar letters denote corresponding part-s in each figure. v

In the drawings, A denotes the basesec1 tion,in which is contained the oil-reservoir, an air-chamber, A', with an annular opening, c, into it above the reservoir, the burner-cone `B,'a'nd its jacket, to neither of which is any novelty asserted. To this section the .globe v5 o'band section C is hinged, so that the entire globe-band lantern above it may be thrown back to give access to the burner and reservoir. This entire globe-band is made out of a single piece of metal, tin being usually employed, and is first struck out Hat by a proper die, when it is of the form shown in Fig. 4, in which a rated burnereollar D, and the dotted annular This blank downwardly at an angle of about ninety deinner edges oi' this flange to the burner-collar D,'and adapted to be secured to the same. thereby holding it in proper position, and movable only with the globe-band. The outer ange, c, is at the same time stamped in vertical lines, and has cut in it, preferably after it is stamped, slits, which subsequently become air-openings e, and are situated immediately above a bead, f, which extends all around this band, which serves to strengthen it at the points where the slits would weaken it. The portions of .the slitted metal are forced inwardly ywith an upward inclination and become the air-openings e ,6, which extend entirely around the band, except in such portions, g, as are required to preserve the essential vertical strength of the band. Over the bead j and into one of these airfopenings the spring-latch E nds a sufcient and convenient latch to enable it to hold the globeband section securely to the base-section.

It will be noted that by reason of the flanges b and c there is formed au air chamber, A2, between them and the top of the air-chamber A", into which chamber currents of' air which come in over the upper part of the globe-band and through the opening e may gain admission through an annular opening, h, between the flange b and the burner-collar. To the top of this globe-band are secured holdingarms F, preferably of brass, upon which the globe G rests, and is held in a central position over the burner and at a little distance above the top of the globe-band, so that there is between the bottom of the globe` and the top of the globeband a clear and unobstructed annular open` a. denote the arms for supporting the perfo' line the divisional point between the inner yiiange, b, and the outer flange, c. p is then stamped by a suitable device, leaving the inner flange, b, sloping inwardly and y grecs, and the arms a a extending from the loo ing, H.`- Itfwill be observed that the bottom of this globe as constructed is a little less in diameter than the outer diameter of the globeband, and considerably greater in diameter than the annular opening h. From this construction it results that currents ofair arising either from wind orthe motion of the lantern entering the opening H are deflected downwardly and inwardly by the :flange b directly into a considerably body of air, more or less in a state of rest, in the chambers A2 and A', and currents of air entering the openings e c are rst deflected upwardly by the upward slope of such openings, and then downwardly by the inner walls of the flange b before they reach the chamber A2.

In the instance of outward movements of air, the inclination of the flange b catches such openings e e. When the lantern is swung from pelsan equal quantity at the other side, and substantial equilibrium of currents is maintained around the burner. So, whether the lantern is raised or lowered, the air forced in l or expelled at the opening H is checked by the smallness of' the openings a h or the actionof the flange b and the openings e in a Way well understood practically, and a substantial equilibrium of currents is maintained and the light produced. To the outer surface of the globe-bandis secured the guard I, made of iron wire. The upright sections of the guard are made in two distinct parts, and in this feature the novelty consists. The part J consistsl of only one of these upright sections.`

which is made of a separate piece of Wire from all the others, and it is secured at its lower end to the globe-band, and has its upper end hookedso as to forma catch passing through a proper opening in the reflector K. rI lhe other part, k, embraces all the remaining v upright sections that may befrequired to com- `angles alittle distance, at which point it is secured, preferabl y by solder, then rises again at right angles as high as its first-named point, then is bent across at right angles, to which bent portion It'z the reflector K is h inged, then descends again at right angles to the globeband, and is again bent at right angles and extends alongthe globe-band, and is secured thereto by solder, and then is bent again at right angles and rises as high as the reflector, vwhere its en'd lc 1s bent in and serves'as a support to the reflector K of the lantern.l A

- breast-wire, L, passes around outside of the ranged, the ends of which are secured by other wires and understraps Z, vertically ar- `'other straps, m, which wrap around the wires and are firmly secured, preferably by solder.

We are well acquainted with the continuous wire guard described in the patent of Chas. S. S. and Alfred L. Baron, No. 105,430, dated October 18, 1870, which is formed wholly of a single wire, one of the upper bends of,which serves to hold a latch fastened to the under side of the reflector. This latch is required to be of strong and eX- pcnsive spring-brass, which mustbe riveted to the reflector. The reflectoris hinged to the vertical wires of two adjacent branches of the guard by means of separate wires wrapped around them and firmly soldered, which is also expensive and difiicult of' manufacture. By the means weemploy we provide an equally effective andy much simpler and cheaper guard, to which the reflector is hinged and latched. A

An ordinary wire bail, m, completes the enumeration of the parts of our lantern, which having thus fully described, we assert therein as new and of our inventionl.
