FRANK RI'IIND, .OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO THE BRIDGEPORT BRASS COMPANY, OF SAME PLACE.
CHIMNEY-LIFT FOR CENTRAL-DRAFT, LAMPS.
SPECIFICATION forming part of Letters Patent No. 577,583, dated February 23, 1897.
Application filed July 27, 1896. Serial No. 600,584. (No model.)
To all whom it may concern:
Be it known that I, FRANK RHIND, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut,have invented certain new and useful Improvements in Chimney-Lifts for Central-Draft Lamps; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has for its object to simplify and at the same time to greatly improve the construction and operation of chimney-lifts for central-draft lamps. WVith this end in view I have devised the novel chimney-lift of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to designate the several parts.
Figure 1 is an elevation of so much of the burner of acentral-draft lamp as isnecessary to illustrate my improved construction, the chimney-gallery being at its normal or lowered position; Fig. 2, a similar view showing chimney-gallery at the raised position; Fig. 3, a section on the line a; a; in Fig. 1, looking down; Fig. 4, a view partly in vertical section,the chimney-gallery being removed; Fig. 5, a view corresponding substantially with Fig. 1; and Fig. 6 is a View corresponding substantially with Fig. 2, but illustrating amodified form in which the lugs or pins are placed upon the body and the grooves which are engaged by said lugs or pins are formed in the standards.
1 denotes the wick-tube, from which extends a flange 2, to which the body 3 is detachably secured in any suitable manner, as by means of a screw-thread, as shown in the drawings. The body is provided with openings 4 to permit air to pass freely. Within the body and at a distance therefrom, so as to leave a space 16 between them, I place an airthe air-distributer as provided with a flange 6, which rests upon a rib 7 upon the body,
and the lower edge of the air-distributer as resting upon an inwardly-turned flange 8 at the lower edge of the body. (See Fig. 4:.) These, however, are mere details of construction which are not of the essence of my invention. The air-distributer may be made of perforated sheet metal, as shown in the drawings, or of wire-gauze, if preferred.
9 denotes grooves, which may be either in the outer face of the body, as in Figs. 1 to 4., inclusive, or in the standards, as in Figs. 5 and 6, and may be diagonal or otherwise, as preferred. These grooves are shown as provided attop and bottom with extensions 10, parallel to the plane of the lamp, which may be used to lock the chimney-gallery at either the raised or lowered position, as will be more fully explained.
The number of grooves is not of the essence of my invention. I have shown three in the drawings,an arrangement which I find to work satisfactorily in use.
'12 denotes a chimney-gallery surrounding the body, which is of ordinary construction and is shown as provided with openings 14 for the passage of a match. Between these openings are standards 13, which are shown as diagonal.
In Figs. 1 to 4, inclusive, I have shown the inner sides of the chimney-gallery as provided with lugs or pins 15, which engage grooves 9 in the body; but in Figs. 5 and 6 I have shown lugs or pins 15 upon the body,
said lugs or pins engaging grooves in the standards, which form a portion of the chimney-gallery.
The operation will be clearly understood from the drawings. Suppose the parts are in the normal position and it is desired to light the lamp. The operator places his hand upon the chimney-gallery and raises it, giving it at the same time a slight rotary motion if the grooves are diagonal. This causes the lugs or pins 15 to travel upward in the grooves and, if rotary movement is continued, will cause the lugs to pass into the upper extensions and will lock the chimney-gallery at the raised position. To lower the chimney-gallery, it is simply necessary to turn it back very slightly and apply the slight pressure space between the body and the air-distributer and another space between the air-distributer and the wick-tube, the object being to prevent the flame from being streaked to the slightest extent by the standards or by any of the connections between the parts. It is in fact immaterial how the air gets into the space between the body and the air-distributer so long as it is supplied to the outer mantle of flame at the top of the wick-tube uniformly and evenly under all circumstances,
a result which is effected perfectly by means of the air-distributer.
Having thus described my invention, I claim- In a central-draft burner the combination with a perforated body, and a vertically-adjustable chimneygallery surrounding and moving upon said body and having an aperture for the passage of a match, of a perforated air-distributer within and of less diameter than said body, so'as to leave an annular space between said distributer and said body, said distributer being also connected to said body at its upper edge, so that all the air passing-through said body passes through the perforations in said distributor.
In testimony whereof I affix my signature in presence of two witnesses.
