LANTERN.

SPECIFIGATION forming part of Letters Patent N0. 237,317, dated February l, 1881. Application filed Deccmber G, 1880. (Model.)

T all wh0m z't mag; concern:

Be it known thatzwc, WILLIAM A. PORTER- FIELD and FREDERIOK S. CLINTON, cf Bellaire, in the ccunty cf Belmont and State cf Ohio, have invented certain new and useful Impr0vement-s in Lanterns; and we hereby dcclare tl1e following t0 be a fu-ll, clear, and exact description 0f enableothers skilled in tl1e art t0 which it; pertains to make and use in, reference being had to the accompanying drawin gs, which form part cf this specification.

Our invention relates t0 an improvement in lantems; and it consists in a guard Which is hinged. upou a suitable supporb which extends up from the bottom pa1t ofthe frame, ancl which guard extends only half-way down the side cf ehe lautem from abovc.

It further consists in a guard which extends only half-way down the side of the lautem from above, and which is supportecl upon one side by a suitable-support, whicl1 extends up fr0m the bottom portion of thc frame, and which is held up0n theopposite side by means of a springclasp, whereby, when the upper portion cf the' guard is relcased from the sprlng-clasp, the entire guard and top of the lautem can be swung back out 0f the way.

lt further eonsists in securing t0 tl1e under side of the guard and the refiector a strip which is inclined diagonally upward, and whicl1 catcl1es 0ver the top of tl1e globe and keeps it in position when the frame is being swung back.

lt; further consists in forming the guarcl cf the ring which extends around thc ceutral portion of the globe cf separate wires, which are bent into a U shapc and then secured t0 the under side cf the reflector, while their lower ends are secured t0 tl1e ring by means of T- shape l fastenings, all cf which will be m0re fully described hereinafter.

The object cf our invention l1as been t0 dispensc with that portion of the guard which extencls around the lower portion of the globe, and t0 attach thc guard t0 thc lower portion of the frarne cf the lautem by means cf devices which will allow 1;he guard to be freely movccl back from over the top 0f the globe, so tha-t ready access can be had to thc interior of thc lautem for the purpose of cleaning and lighting it.

tl 1e invention, such as will Figure 1 1's a side elcvation 0f 0ur irwcntion, showing the guard over the globe in solid lines, and turncd back in dotted lincs. 1*1'g. 2 is an invertecl view 0f the reflector and its attaehments. Fig. 3 is a perspective cf tl1e T-shaped plates by means of which the wire guards are attached t0 the band.

A represeuts the globe, and B the upper portion cf the frame, inside 0f which the lowcr end cf the globc rests. These two arts may be constructed in any desired shape, fcrm, 01 manner. Secured t0 one side of tbis fing or frame B is a support, G, which extends ab0ul: half way up the side cf tl1e glohe, andl wbich has secured 130 its upper end, in any suitable manner, a guard. made bifurcated, and then Lhe two ends are bent 'over the ring F ofthe guard, one end being placed up0u oneside cf 0ne of Ehe mrtical wirres G, and the othe1 0ne being placed 011 the other side 0f the wire G, so as 130 prevent tl1e guard fr0m mving laterally upon the support. This support forms a hinge, upon which the guard turnsin such a man ner that; the Wh0le upper portion 0f the lantern can be turned back from over the t0p 0f the globe, as shown in dotted lines in Fig. l. Secured t0 tlne oppositc side 0f tl1e frameB from the supporl: is a springclasp, H, which catches over the ring F and 0ne 0f the mrtical as t0 hold the top cf the lautem in posicion af- 13er it l1as been once closed over the t0p of the globe. v

II: Will be seen that the guard extencls from above only half t.he length 0f the globe, so as t0 leewe the whole lower port-i0n 0f tl1e globe free in every way, with the exception 0f the support and thc spring-catch. This coustruction causes-much less interference with the radiation cf the light in all directions, protects the globe fully as mach, and gives the lautem a much morc elegant appearance.

The vertieal wires G 0f tl1e guarcl are bent into U shape, and are secure l to 1the under side cf thc reflector by means 0f bancls or strips I, o1 an y other suitable devices, and then have their lower ends secured t0 the ring F by means 0f the T-shaped picces J. These T-shaped clown pieces J are made of an y suitable thin sheel: metal, and havc the horizon tal portion wrapped around the lower end 0f t-l1cwire', whilc the ver- 80 Wires G m such a warmer tical portion asses down under 2Lncl around ohe ring F, and up over ehe tubular portion formed by the part thathas been wrapped a'rouncl the vertieal wire, es shown. This T- shapecl pieee forms a very seeure fastening under any and all cireumstnnees, and gives rather an elegant appearance und finish to thejoint. Also, securecl t0 the under side 0f the reflector are a nurnber of flat springs, L, which catch over the t0p edge 0f 1she globe, and thus prevent the refleetor from being foreed. so tightly downnpon its top as to cause breakage. These sprin gs also tanke up the expansion and contraetion 0f the glass frorn heat and 001d, nn l thus .keep the glass always seeurely held in position.

When the top 0f the lautem is swung back, as shown in dobted lines in Fig. l, he glass is apt t0 beconne more 0r less displaced; und in Order t0 form a gnide,1 attach t0 t he vertical wire G, over which the spring H Catches, and to the under side of ehe reflector, the inelined strip O, whieh, by bearing diagonally against the edge of the globe, pushes the globe back int0 p0sition. This guide is very essential where ita is desired t0 close the top quiekly, f0r it guides the globe back into position mach more quickly than can well be done by band, espeeially shonld the globe be bot.

The refleetor V here shown consists simply 0f arouncl band, such nsi s generally used f0r this purpose.

We are aware that a, lantern-gnard has been made in two arts, ehe npper one of which turns backward, and this we disclaim. Our guard. is made 0f but a single pieee, so as so 1eave' the bottom part 0f the globe perfeetly free, with the exeeption 0f the two parts G H, whieh c0n1e on the sides of the globe, nncl (10 n0b interfere with the radiation 0f the light either forward er back.

Having thus deseribed onr invention, we claiml. In a lautem, the eon1binntion 0f a support 0r hinge which extends up fron1 the 10Wer portion 0f tl1e lantern, a guard whieh extends only a portion of the way Clown the side of the globe fro1n above, and. a spring-catch f0r holding the guard in position, substantially as deseribed.

2. The eombination of the guard and reflector wibh the inclined guicle for moving Ehe t0p porti0n 0f the gloheinto position, substantially as sei; forth.

In testimony ahnt we elaim the foregoing we hure hereunto set; our hands this 3d day 0f Deeember, 1880.
