LAMP.

SPECIFICATION forming part of Letters' Patent No. 280,669, dated July 3, 1883,

Application filed April 9, 1883. (No model.) 7 7 To all whom it may concern.-

Be it known that I, ELIAS B. REQUA, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Lamps; and I do here- .by declare the following to be a full, clear, and

' embodyingthe elements of my invention.

Fig. 2 is a horizontal section 011 the line as of Fig. 1. Fig. 3 is a plan view of the oil-fount detached from the lamp. Fig. 4 is an inverted plan view of the oil-fount, showing air-pass ages, &c. Fig. 5 is a front view of the springcatch for holding the lamp in the supportingframe. Fig. 6 is a detached plan view of the frame secured to the lower ends of the chimneys. Fig. 7 is an inverted view of same. Fig. 8 is a detached plan view of the lower part of the burner. Fig. 9 is a similar view of the perforated cone, which is adapted to rest upon the part shown in Fig. 8. Fig. 10 is a detached perspective view of the wings or airconductors attached to the lower side of the oil-fount, and Fig. 11 is a partial detached plan view of the lamp-burner with the frame illustrated in Figs. 6 and 7 removed.

In the drawings, which represent the invention embodied in a swinging lamp, A denotes the frame thereof, which is properly suspended and sustains the oil-fount, the burner, chimney, and shade or reflector. Between the lower ends of the sides of the frame A is secured the ring B, in which the .oil-fount C is detachably secured.

The oil-fount has a plain cylindrical exterior, and is provided on opposite sides with the spring-fingers D, four fingers, inthe present instance, being employed, each pair of which is connected by the band E. Each of the fingers D is provided with two shoulders, F, as indicated in Figs. 3 and 5, the purpose of which is to permit the attendant to adjust the relation of the oil-fount ward, when the shoulders F will be disen-' gaged and the lamp will slip from the ring. In inserting the lamp, it is only necessary to press the same through the ring B until the shoulders F engage the lower edge thereof.

Heretofore. it has been customary to employ' two or three fingers for holding the lamp -fount in position, and the fingers of the attendant were required to encompass the lower portion of the lamp and press the three fingers inward simultaneously, which was often a difficult feat, on account of the fingers of the hand not being sufficiently long to reach them. By means of my spring fingers, connected by bands E, however, it is only necessary to press on two opposite sides ofthe fount, when all of the spring-fingers will be relieved from contact with the ring B.

In the upper portion of the oil-fount is pro vided the threaded annulus G, in which is se cured the wick-holder H, in the usual manner. This wick-holder forms the central part of the lowersection, I, ol'thelamp-burner. The lower edges of the section I rest upon the upper surface of the fount, while its upper edges are connected with the wick -holder H by the arms J and support the upper section, K, of the burner, as indicated in Fig. 1. The upper or cone portion of the section K of the lampburner has the usual flame-slot, and at the base In withof this coneshaped portion of the section K is number of lines may be employed. In the present instance, however, three fines are illustrated, which, I believe, will be found sufri cient to feed a proper quantity of air to the flame.

Upon the lower end of the oil-fount (l is sccured the frame 0, consisting of the arms a, radiating from the center of the fount to the edge thereof, and provided with the projections 1), which are of proper size to fit transversely into the lower ends of the draft-flues N, as indicated in Figs. 3 and 4-. The purpose of the frame 0 is to direct the air into the fines and to prevent, when the lamp is placed upon a solid surface, the flame from being extinguished, on account of the stoppage of the draft through the burner. It will be obvious, by reference to the drawings, that air, striking the arms a, will be directed to the draft-flucs N, through which it will pass to the chamber formed by lower section, I, of the lamp-burner, thence finding its way through the perforated cone M and upper section, K, tothe flameslot, and through the frame T and air-diffuser \V to the flame on the outside of the burner, all of the air from the fines N being delivered within the chimney.

The chimney l and the outer chimney or globe, Q, are suspended at their upper ends from the dome R by the finger-screws L, and carry at their lower ends the frame T. (Illustrated by detached views in Figs. 6 and 7.) The lower edge of theinner chimney fits closely within the outer edge of the frame T, the chimney or globe Q coming just within the ends of the arms U, radiating therefrom. The central portions of the frame T are removed, forming an opening, V, which is of proper size to slip over the upper coneshaped portion of the sec tion K of the lamp-burner, as shown in Fig. 1, and between said opening V and the edges of the frame is placed the perforated ring or air-diffuser \V. That portion of the frame T between the opening V and its outer edges is slotted or perforated, as indicated in Fig. 7, in order that there may be a free passage of air through it, the said air being thoroughly diffused by the perforated ring V. The frame T is held in place upon the chimneys by the finger-screws F. a

The dome R is slotted and perforated above the upper edge of the inner chimney, P, and below said edge it is slotted or provided with openings Y, through which the air which enters between the chimneys may escape, and which offer a means for permitting the issuance of the light. \Vithin the upper portion of the dome R is provided the contracted extension or shield Z, which forms a continuation of the inner chimney, R, and operates to direct the draft and prevent the introduction into the inner chimney of air which may pass through the perforations in the upper part of said dome. The air passing through the dome creates a vacuum withi u the sh icld Z, and which vacuum acts to increase the natural draft through the inner chimney.

In the lower edges of the dome It are secured the inner edges of the reflector d, as illustrated in Fig. 1. The outer edges of the reflector d will have attached to them, at opposite sides, the slides c, which encompass the sides of the frame A, and are provided with set-screwsf, by which they may be secured in any set position. It will appear plain that by loosening the screwsf the dome, carrying the reflector and the chimneys, with the frame T, may be moved vertically upon the frame A without altering the position of the lamp burner and fount at the lower portion of the frame. \Vhen desired, the chimneys and dome B may be moved upward upon the frame A and the wick lighted, and the dome then lowered until the chimneys are in position; or the wick may be lighted by lowering the fount O, in. the mannerhereinbeicre described. Either method may be followed at will. permitting the escape of air which may accumulate beneath the reflector (Z, the apertures are provided, being shown by dotted lines in Fig. 1.

Around the uppcrsection, K, and at a point below the line of the apertures L, is secured the outwardly-inclined annular flange m, which serves as a bearing upon which the frame T, when in the position illustrated in Fig. 1, may rest, and which prevents the escape of the draft through the burner, except into the burner-cone and inner chimney.

Above the dome R is provided a smoke-bell, a, consisting of the porcelain cup 0, having an aperture at its center, and provided on each side thereof with the metallic plates 1), forming a cap, through which and the said central aperture passes the screw g, which, as may be observed in Fig. 1, holds the two portions 1) together, and at the same time affords a means of securing the smoke-bell in position. By means of the screw 1 the smoke-bell may be detached at will.

The frame A will be suspended from a hook or other suitable means in the customary manner. In order to prevent any jarring or undue swinging of the lamp, I have provided the chains r, having the intermediate springs, s,

the lower ends of the chains being secured to the ring B. If the lamp is employed, for instance, upon a boat or car, the jarring of the vehicle would affect the lamp unless the chains were provided with the springs s. Heretofore it has been customary to employ chains which were without elastic tension, and upon any sudden jarring of the boat or car the chains have often been broken and the lamp bent and disfigured; but I have demonstrated that when. I introduce the springs a they will give to the shock, no matter in what direction it may come, and retain the lamp in almost a vertical position.

I do not limit myself to the employment of a sliding shade or reflector, (Z, since it is plain that the same may be a fixture and the lamp lighted by lowering the oil-fount, in the man- For the purpose of the chimneys and metallic parts of the burner could be handled without burning the fingers, and this is owing to the peculiar-construction described and shown, and the manner in which I supply the flame with air, and provide draftpassages through the same. The flame produced by the lamp constructed as'described is one of unusual brilliancy and steadiness.

What Iclaim as my invention, and desire to secure by Letters Patent, is-

1. A lamp consisting of the suspendingframe, carrying in its lower end the oil-fount and burner, and supporting between its sides the sliding reflector, with means for holding the chimney at its upper edge, substantially as set forth. i
