SPECIFICATION forming part of Letters Patent No. 759,037, flirted May 3, 1904:.
Original application filed April 20, 1908, Serial No. 154,970. Divided and this application filed September 10, 1903. Serial No. 172,704. (No modulo To (til w/tom it may concern:
Be it known that I, IIARPER F. SMITH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Lamps, of which the following a specification.
My invention consists of a novel construction of a lamp, having for its object to provide means to regulate the supply of air to the bottom of the lamp in an effective and novel manner and also to prevent improper and injurious drafts from entering the hot-air chamber from the top of the lamp.
it further consists of a novel ignition-cup.
It further consists of means for providing a supply of fresh air above the lamp-globe.
it further consists of features of construction hereinafter fully described and claimed.
Figure 1 represents a partial central vertical section and partial elevation of a lamp constructed in accordance with my invention. Fig. 2 represents a transverse section taken on the line in :1: of Fig. 1. Fig. 3 represents a perspective View of an upper detached portion of a lamp, showing the supporting device therefor. Fig. t represents a partial vertical section and partial elevation of a lower portion of my lamp detached. Fig. 5 represents in perspective the same portion. Figs. 6 and 7 represent in perspective and vertical section, respectively, the heating-chamber of my device detached. Fig. 8 represents the closure for said chamber.
For the purpose of illustrating my invention I have shown my lamp adapted specially for burning a hydrocarbon vapor; but as my invention relates to the construction of the means for controlling a supply of air and preventing injurious draft and for lighting the lamp the features of construction relating to the burner proper are not illustrated in detail nor will be described, as this application is a division of my application for a vapor-burner, filed April 20, l903, Serial No. 154,970.
Similar letters of reference indicate corresponding parts in the figures.
Referring to the drawings, A designates the burner proper,having an axially-disposed preheating or starting device A and B the frame of the lamp, provided with a globe C, which is suitably supported and which has an opening'l) in its lower portion. Above this opening and beneath the starting device A is lo cated a cup E, which rests upon the feet F.
G designates a deflecting device composed of a base portion ii, an upright stem J, and vertical blades K, the ollice of said deflecting device being to dellect air up into the globe C, which air plays a dual part-iirst, as a fresh-air supply for burner consumption, and, second, to equalize any back pressure that might occur within the apparatus.
It will be understood that the inner deflector or cup E and the outer deflector Ur are held in engagement by a threaded stem L; but as the connection or union of these two parts may be accomplished by various other means I do not deem it necessary to describe this construction in detail.
As shown, the disk or cup E is of greater diameter than the opening 1.) of the lampglobe, so that any air entering thereat is d0. flected toward the sides of the globe C. In this way the glass is kept cool and the mantles protected from air-currents.
l/Vithin the cup E is a layer of asbestos liber or other absorbent material, shown held in place by a disk of wire-gauze or the like. A short tube E passes up through the bottom of the cup E. When the lamp is to be lighted, a portion of the hydrocarbon is permitted to overflow into the cup E, is absorbed by the fibrous material therein, and immediately vaporizes. The flame from a match held below the ignition-tn be E lights this vapor, so that the lamp may be started without a torch and without the tedious waiting usually necessary.
The products of comlmstion from the burner A pass upwardly and into the hot-air cylinder M and impinge against the inverted cone N, whereby the products of combustion are deflected over the top of the outer case or weather-cylinder 1 against the walls of the weather-hood Q, which latter is composed of the angularly-disposed upper and lower conefrusta it and S, united at their bases. The
upper portion of the hot-air cylinder M has seen red thereto the inverted-U or other shaped brace T, whose top portion U is secured to the threaded stem V, having an eye IV thereon, whereby the lamp may be conveniently supported. In the present instance I have shown the inverted cone N as supported from the brace T, and I have shown the cone X as supported from the stem V, while the weatherhood Q is supported from said cone X.
It will thus be understood from the foregoing that the inverted cone N uniformly directs the products of combustion around and out of the hot-air cylinder M. The hood Q, is provided with an opening Z at its top and an annular opening A at its bottom, which latter surrounds the outside or weather cylinder P. It will also be seen that the angle formed by the junction of the inclined sides R and Scuts the air and deflects the same either upwardly or downwardly, so that there can be no improper or injurious drafts within the hot-air cylinder, since said air must pass above the top of the opening Z and below the bottom of the opening A, it being also apparent that the cone X by reason of its location belowthe upper opening Z also assists to prevent any improper or injurious drafts in the hot-air chamber. It will also be ap parent by reason of my novel construction if the lamp should be suspended close to a wall where the air would be deflected downwardly upon the hood Q in case any air should pass into the upper opening Z it would flow over the cone X and out at the bottom opening A.
In some forms of construction I find it advantageous to so proportion the cone frusta R and S that the area of the annular opening A shall approximately equal that of the top openingZ and to place the bases of the frusta substantially in the plane of the exit-opening beneath the deflectingcap X. hen a wind of considerable force is blowing, a portion of the annular lower opening will be shielded by the cylinder P, so that the opening Z will be able to carry off the products of combustion, as well as all the air driven 'into the hood at A. If the wind is deflected downward into the opening Z, it will be prevented by the cone X from passing down the cylinder M and will pass out at the leeward side of the opening A without interfering with combustion.
I have shown the base B of the freslrair chamber U as an annular plate integral with the inner wall D of the chamber. The plate B is of an exterior diameter somewhat less than the interior diameter of the casing E of such chamber, thereby providing an annular opening F for the admission of air, and has annular space between the hot-air cylinder M and the outer or weather cylinder P.
Within the wall D is the hot-air chamber H, located above the burners A and communicating with the hot-air cylinder M.
It is clear that the heated cylinder M will cause a strong upward draft in the surrounding cylinder P. This will be assisted by the radiant heat from the wall D of the hot-air chamber H. By these means an ample supply of fresh air is secured both for the mixing-tube G and for cooling the outer portions of the lamp.
It will be seen that two upward currents are created and discharged into the hood Q. One of these enters the inlet at the bottom of the globe and passes therethrough and through the hot-air chamber H and the inner cylinder M. The other enters through the annular opening F and except the portion which is used to mix with the vapor of the lamp passes through the chamber C and the annular space within the cylinder P.
It is evident that by properly proportioning the area of these two inlets and the outlet of the hood Q any desired draft and volume of air both for combustion and to prevent overheating may be obtained. It is also evident that various changes may be madeby those skilled in the art which will come within the scope of my invention, and I do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
