LAMP.

Specification of Letters Patent.

Patented March 6, 1906;

Application filed July 13,1905. Serial No. 269,535.

To alt whont it may concern:

Be it know that we, Jenn C. AsonENnAon and Josnrn W. AsoHENBAcH, citizens of the United States, residing at Philadel hia, in the county of Philadelphia and tate of Pennsylvania, have invented certain new and useful Improvements in Lam s; and we do declare the following to be a lidi, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to ineke and use the same.

Our invention relates to improvements in lamps, and more particularly to lamps for carriages and other vehicles.

One object of the invention is to provide means whereby oarriagedamps of the ordinary construction now on the market may be readily adapted for burning either. oil or candles, as desired.

Another object of the invention is to so construct the lain that a steady and uniform flow of air wi be supplied to the flame, so that the lamp will burn with the greatest brillianey and without danger of being casually blown out.

Another object of the invention is to im prove and simplify the construction of lam s of this character, and thereby render t e same more durable and efficient in use and less eX ensive to manufacture.

Wit the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter descri ed and claimed.

In the accompanying drawings, Figure 1 is a side elevation with parts in section of the lower portion of a carriage-lamp with our improvements applied thereto, the parte of the lamp being adjusted i or burning a candle. Fig. 2 is a vertical sectional view through the same. Fig. 3 is a view similar to Fig. 1, showing the arts adjusted for burning oil in the lamp. ig. 4 is a vertical sectional view through the parts shown in Fig. 3; and Fig. 5 is a erspective view of the telescoping tubes, sliowing the manner in which the inner one is adjusted.

Referring to the drawings by numeral, 1 denotes the base or bottom of a carriagelamp oi the ordinary or any preferred form of construction. As shown, said bottom is slightly (lished and has upon its u per side the usual lining 2 and upon its un( er side a collar-ball 3, which may be secured by solder, serews, or in any other suitable manner.

Projecting through openings in the lining Z and the bottom or base i is a eonehood 4, which has its large open bottom bearing upon the innerside of the collar 3 and its open upper end dis osed concentric with a guidetube 5. The iiitter projects through the collar 3 and has upon its outer side screwthreads 6 to receive the usuai detachable basetube 7, which serves as a closure for the lower end of the guide-tube.

Mounted to telescope within the guidetube 5 is an inner tube S, within which may be supported an illuminating element 9, which may be either in the form of a candle 10, as shown in Figs. 1 and 2 or the drawings, or in the form or an oil-lamp 11, as shown in Figs. 3 and 4. This sliding inner tube 8 has upon its upper end an inwardly-projnoting annular shoulder 12, which is formed, preferably, by an apertured oep, which is secured as shown.

W'hen it is desired to burn a candle in the y lamp, the inner tube 8 is adjusted vertically in the tube 5. so that the cap 12 closes the opening in the top of the cone-hood 4. tube 8 is retained in this position by means of a coil-spring 13, which feeds the candle upwardly against the shoulder or cap i2. This spring 13, as shown, is covered by a fabric covering 14 and is disposed within the tubes S T, as shown, one of its ends bearing against the bottom of the tube 7 and its opposite end being secured to a follower 15, which is adapted to engage the bottom of the candle 10 and slide in the tube S. Vlhen it is desired to burn oil in the lamp, the candle 10 and spring 13 are removed and replaced by the oil lont or reservoir 16 and its attached burner 1?, and the inner tube 8 is moved downwardly into the guide-tube 5, so that necessary draft of air may pass between the cone-hood 4 and said tubes, as indicated by the arrows in Fig. 1i of the drawings. The adjustment ol' the inner tube 8 in the guide-tube 5 may be eileeted in any desired manner; but we preferably provide upon the tube 8 a projection or stud 18, which slides in a slot 19, formed in the lower end of the tube 5. When the tube S is in its elevated position, (shown in Fig. 2,) said projection 18 is seated in the upper end of the slot 19, and when in its lower position (shown in Fig. 4) said projection is engaged Said with the bottom of the tube 5, so that said tube and the attached lamp will be firmly connected to the tube 5. It will be understood that the tube 8 when it is lowered is dle, may be of any desired form and construction and may be secured in the tube 8 in any suitable manner. As shown in Figs. 3 and 4 of the drawings, the oil font or reservoir 16 is in the form of a tube or cylinder, which is adapted to be inserted through the open lower end of the tube 8 and which is retained therein by screwing the burner 17 down into the screw-threaded opening in the top of the reservoir 16, so that the two parts will be clamped 4upon the shoulder or cap 12, as clearly shown in Fig. 4. The burner 17 is of such size that sufficient space is left between its top and the opening in the top of the cone-hood 4 when the tube 8 is in its lowered position to permit a draft of air to pass upwardly to the fiame. The stem 20 of the ratchet-wheel, which raises and lowers the wick of the burner 17, is adapted to project through a slot 21, formed in the rear side of the cone-hood 4 adjacent to its upper end, so that said burner may be readily inserted in the conehood through the opening in its top. In order to provide a steady and uniform draft of air for the lamp, the collar 3 is formed adjacent to its lower end with an annular series of apertures or perforations 22, and within the space between the tube 5 and conehood 4 are provided an air-spreader 23 and a partition-plate 24, of foraminous or reticulate material. This partition, as shown, is in the form of a perforated or apertured ring secured to the upper end of the tube 5 and to the interior of the cone-hood 4 by solder or in any other suitable manner. The air-spreader 23 is in the form of an inverted cone,which is slightlv dished and is secured upon the tube 5, so t iat it causes the air entering through the openings 22 to take a circuitous course through the device, as indicated by the arrows in Fig. 4 of the drawings. This spreader, together with the perforated rin or partition 24, breaks up sudden puffs o' wind and causes a steady uniform draft of air to be supplied to the lamp-burner.

The construction, use, and advanta es of the inventionwill be readily understoo from the foregoing description, taken in connection with the accompanying drawings. It will be seen that the lamp may be quickly and easily adapted for burning either candles or oil and that in either case a simple, durable, and efficient construction is provided.

It will be understood that these improvements may be applied to lamps of any kind,

lamp is provided.

While we have shown and described the preferred embodiment of our invention, it will be understood that we do not wish to be limited to the precise construction herein 4set forth, since various changes in the form,

proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
