l To all whom it may concern.-

Ee it known that 1, Lnwrs E. Rims, of' theV city, county, and State of New York, have'in` vented new and useful Improvements in Lan! tern-Guards, of which the following isa specification. l

This :invention relates to that class of guards which are secured to the perforated plates or base-supports upon which the globes rest in v ro tubular lanterns, and has for its object to produce a guard which permits the easy-insertion and removal of the globe without removing the perforated plate from theliftwires orl other parts to which it is attached.

` My invention consists ofthe improvements which will be hereinafter` `fully set forth, and pointed out in the claims. I

In the accompanying drawings, Figure 1 is a front elevation of a tubular lantern pro- :o Videdvwith nay-improved guard. Fig. 2 is a detached perspective view of the perforated plate and guard. Fig. 3 is a top plan view of the same parts. Fig. 4 is a sectional side elevation of the lantern, illustrating the manner of inserting and removing the globe. Fig. 5 is@ bottom plan view of the perforated plate and guard, showing a slightly-modified means for securing the guardwires to the plate.

Like letters of reference refer to like parts 3o `in the several gures. s

A represents the oil-pot; a, the air-chamber resting thereon,and a the burner surmounting the airchamber a. B B represent the upright airtubes, b b the lower horizontal 3 5 branches thereof secured to the top of the oilpot, and c c the upper horizontal branches connecting with the vertical central tube, d. D represents the bell, loosely mounted-on the central tube, d, so as to slide thereon. e e reparo resent the liftwires,secured with their upper` ends to the bell D. E represents the perforated plate or base-support, which is attached to the lower ends of the lift-wires e e, and upon which the globe F rests. G represents the catch or clasp, which is attached to the bell and which engages with the upper end of the globe and holds the latter in place. All of these parts may be of any ordinary or suitable construction.

5o H H represent the two bent wires or bows `rections, so as to cross each other, and extend `such manner that the globe can only be reof4 which the guard is composcdand which are secured with their lower ends to the perfo`- rated plate E by soldering their lower portions to the rim o f said plate, as represented in Fig. 2, or by bending their lower portions,

passing the bent portions upwardly` through holes in the `perforated plate, and clinching them on the upper side of the plate, as repre sented in Fig. 5. Y The two `bows 0r guarde wires are arranged obliquely in opposite di- 6o vupwardly beyond thebrossingpoints h 'h on both sides of the globeand on the inner sides `of the air-tubes to the proper height to protect the globe. The two bows are preferably secured together at the crossing-points h h by soldering or otherwise. The guard-bows clear the globe at all points, so as not to `come in `contact with the same,which would render the globe liable to breakage by the transmission 7o of blows applied to the guard or by unequal I chilling of the globe whenheated. The parts s of the guard-bows which extend obliquely upwardly beyond the erossing-points h are separated by depressions or open spaces I I on the front and rear sides ofthe lantern,which permit the globe to be inserted and removed by iuclining it WithoutA disconnect-ing` the perfo' rated plate from the lift-wires, or without removing the globe-supporting plate from the -8o lanternframe. Thisconstruetion permits the sideP portions of the'guard to be ext-ended up` wardly to a sufficient height to properly protect the globe without interfering with the insertion and removal of the globe, while itwould 8 be impossible to insert and remove the globe without disconnecting the perforated plate fromthe lift-wires ifthe top portion ot' the guard extended around the globe horizontally in a guard of the same height. This constructionalso avoids making the guard partly of movable parts,which areliable to become '1nfastened in use. y

When the clasp G is secured tothe bell in 5 moved forwardly or toward the front side of 9 the lantern, as indicated in Fig. 4, the depression 1 on the rear side of the guard does not i come into use for inserting and removing the globe, but serves merely to render the guard roo symmetrical on the front and rear sides of the lantern.V \Vhen the perforated plate is`capable of being tilted, as illustrated in Fig. 4, the

insertion and removal of the globe is further 5 facilitated by the inclined position which the perforated plate assumes. i

My improved guard'occupics butlittlc space.

It is constructed at `comparatively small cost and presents a neat and attractive appearance,

10 while being perfectly rigid and reliable 1. The combination, with the tubular 1an- Lern-lrame having its base provided with a burner, of a globesupportin,r plate surround- 15 ing.,r the burner, and a rigid guard secured to said plate, open at the top,and provided on the front side of the lantern-frame with a depression through which the globe can be inserted and removed, substantially'as set forth.

2. The combination, with the tubular lantern-frame having its base provided with a burner, of a globe-supporting plate surrounding theburner, and rigid oblique guard-bows secured with their lower ends to said plate and having their raised portions arranged 0pposite the inner sides of the' tubes, substantially as set forth.

W'itness my hand this 14th day of November, 1887.
