SPECIFICATION forming part of Letters Patent No. 451,413, dated April 28, 1891.

Application filed October 3, 1890.

To all whom it may concern:

Be it known thatI, JAMES XV. SEE, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Lanterns, of which the following is a specification.

This invention relates to improvements in lanterns designed for projecting light downwardly through a stencil or transparency to a plane surface, as a sidewalk, for advertising purposes, &c.

My improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a front elevation of a lantern exemplifying my improvements; Fig. 2, a central vertical section of the same; Fig. 3, a plan of the frame-ring and funnel; Fig. 4:, a horizontal section of the chimney; and Fig. 5, an edge view of a reflector-spring.

In the drawings, A indicates a strong-castmetal frame-ring of considerable depth and with its axis vertical; B, a hollow lug or ear projecting radially from one side thereof; 0, a similar lug, not necessarily hollow, projecting from the opposite side of the ring; D, a

rod or tube similarly extending upward from the lug O, the two tubes converging at the top of the structure; F, a T uniting the upper ends of the two tubes and serving as a means by which gas-pipe communication may be made with tube D; G, a gas-cock in tube D; H, a burner-pipe disposed within the frame-ring and connecting at its outer end with the hollow of lug D and having its inner end projecting up in the center of the frame-ring to receive a gas-burner; J, a nut on the lower end of rod or tube E under the lug G; K, a nut on the same rod over thelug; L and L, plugs in the lugs B, the presence practical construction it is found desirable to produce the hollow in the lug by drilling, which produces extra openings to be closed, plug L, however, having an additional office; M, a gas-burner upon the inner end of the burner-pipe, this burner being disposed above the top of the frame-ring; N, the glass chimney of the burner; O, a funnel supported Serial No. 367,014- (No model.)

within the frame-ring and firmly secured at the upper edge of the ring, in the exemplification by turning the upper edge of the funnel downward over the upper edge of the frame-ring; P, acylindrical nozzle removably attached to the lower end of the funnel; Q, a bayonet-joint lock for securing the nozzle to the funnel; R, a ledge or rest formed upon the inner wall of the nozzle near its top; S, a

stencil or transparency resting upon this ledge; T, a lens-tube disposed within the nozzle and adapted for sliding vertical adjustment therein; U, a lens secured in the lower end of the lens-tube; V, a reflector, preferably parabolic, with its lower edge engaging the upper edge of the funnehthe diameter of the base of the reflector corresponding substantially with that of the top of the funnel, the lower edge of the reflector preferably flanging over the top of the funnel, so as to become doweled thereon and be at the same time readily removable; W, an open nozzle at the top of the reflector and forming a part of the reflector, this nozzle encircling the upper portion of the glass chimney N and being as near the size of the chimney as the convenient removal of the reflector will permit, this reflector-nozzle projecting some inches above the top of the glass chimney; X, the reflectors chimney fitting upon the nozzle, so that it can be rotated thereon, and forming an upward prolongation of the nozzle; Y, an opening through the wall of reflector-chimney and reflectornozzle at a point in height just over the top of the glass chimney, this opening being either at one side of the structure only or at both sides, as indicated in Fig. 4; Z, a hood over the top of the reflector-chimney; Ct, airholes in the wall of the funnel below the burner and below the top of the frame-ring; b, reflector springs or clips attached to the funnel and engaging the flange at the lower edge of the reflector and serving when engaged to prevent the displacement of the reflector from the funnel.

Any desired device is to be cut in the sten- ICO beneath the lantern upon an enlarged scale. The lenstubc is adjusted vertically by sliding in the nozzle 1 to secure sharpness of projection.

The stencil lies loosely on its support R, the intention being to provide for the ready change of the stencils. 13y disengaging the nozzle I from the funnel at the bayonet-lock the nozzle P and lens-tube may be withdrawn from the lantern and a new stencil readily placed.

The pipes D and E form aharp for the sus pension of the lantern. The frame-ring is firmly secured to the harp and forms what might be called the firm foundation on which the lantern is constructed. It is of such strength and firmness of attachment to the harp as to prevent the wind, acting on the lantern proper, from twisting the parts out of line with each other, and it will be noticed that the harp attaches to the lantern proper at about the middle of its height, so that the leverages acted on by the wind are about as short as possible and equalized.

In constructing a harp of bent pipes it is very diflicult to secure uniformity of the ultimate length of the two sides. In the construction shown synnnetry of construction may be secured by manipulating the nuts J and K to lengthen or shorten the pipe E till the lantern structure is plumb.

The lantern structure is the product of the sheet-metal worker, and it may be formed complete and then set upon and secured to its frame-ring, the frame-rin g thus not entering into the assemblage until the lantern proper is complete. Air for combustion is supplied at holes a, and the downwardly-projecting frame-ring forms a curtain to keep the light in and the rain and wind out of these holes.

The reflector chimney and nozzle being nearly the same size as the glass-ehimney adds to the draft height of the glass chimney, causing the major portion of the air of combustion to reach the burner-flame. The lantern is to be lighted at the top of the glass chimney,thereflector-chimneyXbeingturned so that the opening Y therein coincides with the corresponding opening in the reflectornozzle. The reflector-chimney is then to be turned to close the opening, as indicated in Fig. 4-

The reflector sets removably upon the top of the funnel and is held by the spring-clips b. The reflector, with its attached nozzle and chimney, may be readily removed and left off and the lantern then employed as an ordinary street-lamp; but I prefer when the lantern is thus employed to replace the opaque reflector V and its chimney X and hood with a duplicate formed of glass to protect the burner from the weather, and I also contemplate the employment of transparent glass for the funnel O in cases where the lantern is to be employed for other than purposes of projection.

The harp provides for the suspension of the structure from a point centrally above the lantern; but where a side support instead of a top support is required then the harp as a harp will be dispensed with and the frame ring will have its hollow lug B connect directly with such horizontal supporting-pipe as is to be availed of, such pipe screwing into the lug in place of plug L.

I claim as my invention 1. In a projecting lantern, the combination, substantially as set forth, with a funnel, a reflector, a burner, and a lens-tube, of a nozzle adj ustably locked to the lens-tube and sepa- 'ably engaging the base of the funnel and provided with a support for a stencil.

2. In a projecting lantern, the combination, substantially as set forth, with a funnel, a burner, a stencil-support, and a lens-tube, of a glass chimney for the burner, a reflector inclosing the burner, and a hooded chimney forming an axial extension of the reflector encircling the top of the glass chimney.

substantially as set forth, with a funnel, a

bu rner,a stencil-support, and a lens-tube, of a glass chimney for the burner, a reflector inclosing the burner, a nozzle projecting from the reflector and having an opening above the top of the glass chimney, and a hooded chimney mounted for rotation on said nozzle and provided with a corresponding opening.

4-. In a projecting lantern, the combination, substantially as set forth, of a funnel, astencil-support and lens-tube at the base of the funnel, a reflector supported on the top edge of the funnel, and a burner within the reflector.
