Specification forming part of Letters Patent No. 36,649, dated October 14, 136:2.
To all whom, it may concern:
Be' it known that I, PETER HAYDEE', of the city of Pittsburg, Allegheny county, and State of Pennsylvania, have invented a new and useful Improvement in Lamps; and I do hereby declare that the {ellen-'ing is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification.v
In the diii'erent figures like parts of the burner are represented by the same letters.
Figure l represents a vertical central section ofthe burner, and shows the mode ofoperating the slidingwick-tube. Fig. Zrepresents a horizontal projection of the burner with the upper and inner caps removed, and shows the chimney-ring and clasp and the position of the wick-tube, and the wheels for operating the wickftube and wick at the base of the burner. Fig.,3 represents the mode of attaching the auxiliary wick and the operation ofthe principal wick. Fig. Ll. represents a perspective of the burner placed upon a'lamp, and shows the shape'of the upper cap.
a a represents the base or basketlike pai-t of the burner, which is perforated for the admission of air, and includes th-e chimney-ring, whe'rrthat is used..
b I) represents a cone or cap attached to the base by means of Vspriiig-catches, as shown at p p p, and is divided at the top into four parts. Two opposite parts are b ent outward and form projections, as shown at c c.. rIhe other two opposite parts are about the width of the wicktube at the base, and somewhat semieireular at the top, convex on the outside, and inclined toward each other, formingthc mouth of the burner, as shown at d.
cie shows the projections of the cap b.
d shows the mouth of the cap c e represents the inner cap or conc, which covers the pinion-wheels. The upper part extends nearly to the base of the mouth of-the cap b. Thewick-tube passes through it, leaving a small erevi ce at each side for the passage of vapor and gases from the body of the lamp vdirectly into the ilame, thus preventing the escape of unconsumed gases. This cap is eireular at its base and a attened cone iitting the wick-tube at its edge at the top.
f represents thewiek-tube. It is perforated on one side, -so that the eogs of the pinionwheel Work into it lfor raising or lowering the wick-tube. On the other side there are two strips cut out of it to give play to the wheels running the wick. The strip remaining between the wheels is bent inward at the bottom for the suspension of an auxiliary wick, which may be common candle-wick or fluid-wick, as represented at'Z m' Z. v
g represents the pinion for operating the wicletlibe.
h represents the pinion i'or operating the f1? I represent a wire clasp for holding the chimney. It ishinged in the middle, and bent as shown at v, and it extends only about twothirds around the chimney-ring, and clasps on its edges, as shown at n n. It can be thrown hack, as in Fig. 4, and clasped on after the chimney is inserted.
7.'. represents the principal wick.
7 I represent the auxiliary wick.
m represents the hook fort-he suspension of the auxiliary wick.
o o e represent three ridges for the chimney to rest upon. v
a a represent the clasps of the chimneyholder.
p p p represent the spring-catehcs for holding the cap Z.
q represents the collar of the burner, which is -i'astened to the lamp.
r i' represent the lamp in perspective. y
s s represent an open space in the base-of the burner, to form aconnection between the lower chamber of the burner and the font of oil, and thus preventing the accumulation of heat in this part of the burner, and condensing bythe cooling influence of the font below any vapors that may arise.
Having now described the burner, I will proceed to describe its operation.
This burner is designed to burn carbon or coal oil either with orwithout the use-of a glass chimney; but it will also burn camphine, burning-fluid, whale-oil, and the other illuminating-oils. The font heilig supplied with oil and the burner being supplied with wick, to light the lamp raise the wick by the pinion l1. and light it. It can be ignited at any part of the mouth of the burner. The quantity of light and also the amount of draft are regulated bythe movements of the wick-tube and Wick, both of which can be run up the mouth of the burner. The draft is increased by lowering the sliding tube inthe mouth of the burner, and vice versa, and. the quantity of light for each position of the sliding tube depends on the elevation of the wick above the.
tube. rIhus a perfect control is had over the draft and light, and the burner will burn with or Without a chimney. The projections c c serve to spread the dame, and by supplying the edges of the ilame with a current of hot air from the cap b prevent their smoking. As a small portion of the flame rests within the mouth of the burner the light is very portable and is not easily blown out by the wind, so much so that it can be carried in the open air even withastrong draft of wind. The cap b, or any ordinary cap, can be used when a chimney is put on. Y. A much shorter chimney can be used with the cap b, and a more mellow light obtained than with the ordinary chimney-lamps. Thechimney is designed to rest on three or more ridges in the chimney-ring, to prevent it from getting too hot. The cap b may rest on ridges in the same way, to prevent the base of the burner from getting overheated. The auxiliary wick is designed to keep up a regular supply of oil on the princlpal wick, and when the oil is Yyerylight and the font shallow the auxiliary wick can be left out; but in coal and carbon oil much diiculty has been experienced when the oil is heavy and the font deep, and this auxiliary Wick, lying in contact with the principal wick at the point m,is designed to remedy this difficulty. Y
In small lamps, designed Vto be used entirely Without a chimney, the chimney-ring can be omitted. The shape of thebase a a is not ma terial, so that it is suflicientl y perforated. The pinion g may be reversed, with the handle on the opposite side from the pinion h. Instead of the whole tube f sliding, it may have a slide at its top answering the same purpose.
In the above specicationI claim and desire to secure by Letters Patent of the United States- A wire clasp extending about two-thirds around the chimney-ring, shaped and operating as described.
