Specification of Letters Patent.

Patented @ll'uly 2, 191e To all whom it may concern:

Bc it known that l, CHARLES E. GODLEY, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Oil- Lamp Font Fastener, of which the following is a specification.

This invention relates to connecting mechanism adapted to secure the fonts and burners of oil lamps in proper position relative to the bodies or superstructures, and at the same time, substantially prevent the entrance of air in quantities sufficient to extinguish the llame at this point of connection. It also consists in forming both the body and the font with pairs of concentric cylindrical flanges, the outer flanges of the font and body being formed to interengage and lock, and the inner flanges of the font and body being formed with interengaging sealing portions, the inner flange on the font preferably extending to a height above the lower edge of the skirting of the burner mounted on the font.

In the accompanying drawing, Figure 1 is an elevation-section of my improved lamp. Fig. 2 is a bottom plan view of the spring that holds the burner down on the font. Fig. 3 is a plan of the burner. VUEig. 4 is an elevation showin@ the relative relations of the parts of the body or superstructure.

Similar reference characters refer to like parts throughout the several views.

ln the drawings the body or superstructure of this lamp consists of a casing 1, a door 2 connected to the body by means of a hinge 3, a head 4 held down on the casing 1 by means of a chimney 5 and nut 6 as described in my former Patent Number 1,101,021, dated June 23rd, 1914, a lining 7, a font 8 and a burner 9. The head is provided with openings 10 through which the burnt gases may escape and with holes 11 through which freshair can enter and pass down between the casing and lining. The door may have a thumb-piece 12 by means of which it may be opened and closed.

This present invention has to do with the construction of the interengaging parts of the font and superstructure and with the parts ilnmediately adjacent thereto.

lllhe font 8 is united to a top 14 which has an external flange 15 provided with a verti cal notch or slot 16 and the bayonet slots 17 that .are adapted te receive the pins le ser ried by the annular Hangs 19 on the body 1. Within and concentric with this flange 15 is an annular plate 21 having a guard flange 22, and having an internal flange 23 beaded over the inner edge of the top 14 to unite the parts. The burner 9 has an IL shaped flange, one leg 24 of which is horizontally disposed and having a plurality of air holes 25, the other leg 26 of said base Hange depending from the outer edge of said horizontal leg below the upper edge of' said guard flange 22.

The body 1 is formed with a depending annular flange 19, within which is secured a sealing ring substantially U shaped in cross section, one leg 27 of the ring being secured to the flange 19 and the other leg constituting a flange 2S that engages the guard flange 22, and thus prevents air from passing through the bayonet slots 17 into the body of the lamp,

Secured to the lining 7 is an annular plate 29 having downwardly extending resilient lingers 30 that engage the horizontally dis posed leg 24 of the lL shaped flange on the burner and holds the burner seated on the font. The edge of the lining may extend beyond the inner edge of' the plate 29 andl be formed with teeth 32 that extend in close proximity to the burner, as indicated in Fig. 2. The flange 19 is cut away at 33 to permit the wick shaft 34 to move with the font. A washer 35 of leather may be employed to form a tight joint between the font and burner.

The font 8 is usually made of a sheet of soft ductile metal, pressed to the form shown in Eig. 1. The edge of the font is left of sufficient size to loosely receive the top 14, sometimes called the neck of the font, which has previously been formed with' a circumferential groove into which said edge may extend. The top and font are then placed between proper dies and pressure is applied to these dies, causing the upper part of the font to be reduced in diameter, and the edge of the font to be forced into the circumferential groove at the base of the flange 15. This securely unites the font to its top. The joint is then completed to make it oil-tight by soldering.

When the font is secured to the case 1, the slots 16 and 17 will be substantially completely covered by means of the flange 19 so that all air necessary for combustion must come down around the chimney I3 and the lining 7. This passage conducts a sufficient amountv of; air tothe burner to properly sustain combustion, but it prevents sudden gusts of air which are especially liable to occur where such a lamp is mounted on an automobile traveling at high speed.

' The details and proportions of this construction may all be changed by skilled designers without departing from the spirit of my inyention.

I claim:-

1. In af lamp, a superstructure, an annular flange' on the lower portion of said super-- structure,an oil receptacle, an annular flange carried by the upper portion of the said receptacle, locking means to secure one of said flanges within the'other, a burner mounted on the oil receptacle, means mounted on the superstructure to hold'the burner in position, a depending sealing flange separate and apart from the burner mounted on the superstructure, and a second sealing ange projecting 'up from the oil receptacle into engagementv with the sealing flange on the superstrilcture.

2l In aglamp, the combination of a body andan oil font, a pair of telescoping locking flanges, one'mounted on the body and the otherl on the font',a pair of telescoping sealing flanges, one connected to the body and the other to the font, a burner on the font separate from but within said flanges, and means to'hold the burner in position.

3. In a lamp, the combination of a body and a lining therefor, an oil font, a pair of telescoping flanges for securing the font to the body, one of the flanges extending down from the body and the other extending up fromtlie font, a pair of sealing flanges, one sliding within the other, one mounted on the body and the other secured to the font, a burner mounted on the font, separate from but within said flanges, and resilient means mounted'on the lining to hold the burner in position.
