p LAMP.

To all whom it may concern.'

Be it known that I, LiNnsLnY ScHnPMoEs, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Lamps, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appel'n tains to make and use the same.

This invention relates broadly to illuminating apparatus, but as certain of its characteristic advantages prominently appear when it is embodied in an apparatus of the type commonly known as gas lamps,77 it will be conducive to clearness to disclose it in such connection.

One object of this invention is to provide a lamp, especially adapted for being susendec from a wall or ceiling, in which the urner will be fully protected by means of globes adapted to evenly diffuse the emitted light, and in which said globes may be replaced with the greatest of facility should they become fractured.

Another object is to so arrange the parts of an apparatus of the foregoing nature that the products of combustion may be effectively disposed of and in which gas may be burned with the greatest of efficiency owing to the fact that fresh air is admitted lin the most advantageous manner.

Other objectsand advantages will be in pfart obvious and in part pointed out hereina ter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of various possible embodiments of my invention,-Figure 1 is a sectional elevation of my invention, showing the formation and relationship of the various parts when assembled. Fig. 2 is a horizontal section through line 2-2 of Fig. 1, showing cer tain details not clearlyapparent from the latter figure. Fig. 3 is a detailed section showing the manner in which the hinged inturned ledge or ring is secured to the supporting member. Fig. 4 is a detailed crosssection showing the construction of f the catch for preventing the swinging of the Specification of Letters Patent.

hinged ledge. Fig. 5 is a side elevation of the device shown by Fig. 4.

Referring now to the accompanying drawings, 1 denotes the annular supporting meme ber, which preferably is continuous and is provided with inwardly extending integral ugs 2 which are spaced apart, as shown by Fig. 2, to provide for the admission of the fresh air necessary for supporting the combustion of the burner. An annular defiector 3 bears against the innermost extremities of the lugs 2 and is firmly secured thereto by means of small screws 4, as will be readily understood. The deflector preferably narrows toward its lower end, as indicated by 5, so as to afford a free passage for the incoming fresh air, as will be presently more clearly understood, and while I have shown the defiector as terminating a considerable distance above the burner, it is nevertheless to be clearly understood that I may, if desired, further extend the same and may also considerably modify the shape of said deflector without departing from the spirit of this invention. The said supporting member may be carried by the lower ends of one or more arms 6 by means of an elbow 7 which has a threaded stud 8 in engagement with the sup. porting member, and one or more of these arms may form conduits for the passage of gas to the burner. This latter arrangement will be understood more clearly by referring to the right hand side of Fig. 1, in which 9 denotes a gas pipe in communication with a hollow elbow 10, which latter enters an orifice in the supporting member. I/Vhile subject to modification in this particular, the orifice referably extends through one of the inwardIy extending lugs, as shown, and an elbow 11 takes into said oriiice and carries a gas pipe 12 which, it will be noted, passes downwardly at a distance from the path of the products of combustion from the burner so as not to become heated thereby. This pipe leads to the burner 13 from underneath for the same reason, and here it may be menn tioned, although this will be apparent to those skilled in the art, that any preferred type of burner may be employed in connection with this invention according to the particular uses to which it is to be put.

For the purpose of protecting the burner against excessive drafts, and to insure the most eflicient combustion of the gas, this invention proposes an underlying globe 14 which may or may not be apertured. A very satisfactory manner of mounting this globe is to hang it from the aforesaid supporting member. To this end a hinge plate 15 (see Fig. 3) may be secured to the supporting member 1 by means of small screws 16. Plate 15 provides a suitable hinge 1S, to which is pivcted an annular ring 19 providing an inturned ledge 2O which in turn is preferably also provided with a small recess 21 for the reception of a strip of asbestos or other resilient acking 22 (see Fig. 1). The lower globe wil have an outturned edge or flange 23 adapted to rest upon the packing 22 so as to prevent the metallic parts from coming in contact with the glass, and in this manner obviating any fracture or undesirable strains due to such contact.

The aforesaid parts may be maintained in place through the agency of an annular resilient ring 24 which is in turn secured to the inturned ledge by means of small screws 25. The retaining ring may have its inner end dished in the manner shown by 26 s o as to render it better adapted to conform to its purpose.

It will now be apparent that the depending or lower globe and the ring from which it is suspended form a structure which is capable of being moved as a unit about the pivot of the hin e 18, and in order that the same may be he d in its normal position shown by Fig. 1, a latch of any suitable construction may be resorted to. Thus the arrangement shown by Figs. 4 and 5 may be adopted and is preferred because of its simplicity, merely consisting of a catch arm 27 pivoted at 28 and normally held in engagement by means of a flat U-shaped spring 29 which is carried by a casing 30. To this end, portions 31 of this casing may be stamped out, and the end of the spring may be passed through the sockets thus formed.

This invention also proposes an overlying dome or globe 32 which has its edges protected by a wrapping of asbestos 33. The lower edge of this dome preferably rests directly upon the inwardly extending lugs 2, and, as will now be understood, fresh air may freely enter through the spaces between the said lugs. This fresh air passes downwardly, being directed toward and along the under lying globe by means of the defiector 3 so as to constantly supply the burner with fresh air.

The overlying dome or globe carries at its up er end a crown 34 which serves as a globe ho der, i. e. a means instrumental in holding the globe in place, and may also serve as an outlet for the fumes, and for the purpose of adding rigidity to the whole a number of arms 35 extend downwardly from said crown and terminate in apertured ends 36 which lie adjacent the supporting member. Each end may be provided with a thumb-screw 37 whose shank is in engagement with the supporting member, as shown. By this means it is possible to very easily adjust the tension brought upon the overlying globe, and it is to be noted that the crown may be removed, and a new globe substituted whenever desired, with the utmost facility owing to the fact that the finger grips of the thumb-screws lie exteriorly of the parts of the lamp. The arrangement of means capable of quick manipulation is of great importance in lamps which are used in connection with railroads and the like, since time is a very important element going to make up the commercial success of the same.

Having described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. A lamp comprising, in combination, an annular supporting member, a burner positioned thereby, a globe having one end in abutment with said member, a globe holder in abutment with the opposite end of said globe, and means for adjustably securing said globe holder to said member.
