Lighting and Extinguishing Device. NO.236,939. Patented Jan. 25,1881.
UNITED STATES PATENT OFFICE.
WILLARD D. DOREMUS, OF WASHINGTON, DISTRICT OF COLUMBIA, AS- SIGNOR TO HIMSELF AND SAMUEL R. STRATTON AND JOHN T. STRAT- TON, STRATTONVILLE, PENNSYLVANIA; SAID SAMUEL R. STRAT- TON ASSIGNOR TO J. KEMP BARTLETT, OF BALTIMORE, MARYLAND.
LIGHTING AND EXTINGUISHING DEVICE.
SPECIFICATION forming part of Letters Patent No. 236,939, dated January 25, 1881.
' Applicationfiled June 24,1880. (Model) Apparatus for Lighting and Extinguishing Lamps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, makingapart of this specification, in which- I Figures 1 and 2 are perspective views, re-
spectively, of the front and rear sides of my impi ived lantern, the extension-top being raised of the rear side of the lamp, the extimguisher-v 1 the latter view. Figs. 3 aud t are like views cap being-over the wick-tube in the former and withdrawn therefrom in the latter and the wick lighted. Figs. 5 and 6 are plan views of the upper side of said lamp, with its parts arranged as shown in Figs.3 and 4, respectively. Figs. 7 and 8 are rear elevations of the same, the mechanism being arrangedas shown in Figs. 5 and 6, respectively. Figs. 9 and 10 are, respectively, sections upon lines a: a; and z z of Figs. 5 and 6, and Fig. 11 is a perspective view of the match-holder detached from the operative mechanism.
Letters of like name and kind refer to like parts in each of the figures The design of myinvention is to furnish a lantern which may be automatically lighted and extinguished, and in which ordinary friction-matches may be employed; and to this end it consists, principally, in the construction of the rotating match-holder and its combination with the spring. friction-arm, substantially as and for the purpose hereinafter specified.
It consists, further, in the means employed for rotating the match-holder, substantially as and for the purpose hereinafter shown.
It consists, finally, in the means employed for automatically closing the extinguisher over and removing it from the end of the wick-tube, substantially as and for the purpose hereinafter set forth.
In the annexed drawings, A represents the casing of my lantern, constructed, preferably,
with a rectangular shape, its front and sides being composed of sheet metal, and its back of wood or other like non-conductor of heat. Within said front is provided a glazed lightopening, a, while at its upper end is a ventilator-cap, B.
In order that more and better ventilation may be provided when the lantern is not exposed to a high wind, the top a of the casing A is secured to and forms part of a section, A, which telescopes within the upper portion of said casing, and at each of its sides is provided with a number of openings, through which the heated gaseous products of combustion may pass outward. Said section may be set at any point between the limits of its movement, and is held in place by the spring of the sides of said casing.
Two handles, 0, hinged to or upon the back of the casing, and arranged to be folded flatly upon the same when not in use, enable the lantern to be carried in the hand of a person.
Fittedwithin the lower open end of the casin g A is a reservoir, D, which corresponds thereto in horizontal size and shape, and is held in place by springs E at its ends, or by other suitable means.
Within the upper front side of the reservoir D is provided a right-angled recess, d, which extends to or near the transverse center of the same, while from the upper side of said reservoir, in front of said recess, a wick-tube, F, extends in a curve upward and forward, and delivers a wick, f, horizontally from its open end.
Directly below the wick-tube F, a stud, Gr, projects horizontally rearward from the front side of the recess D, and upon the same is journaled a disk, H, which, within its front side, is provided with a series of radial grooves, h, that are equidistant, and are slightly wider at their inner sides than in front. Each groove it receives a friction-match, I, the body of which is broken away, so as to leave a length of about one-half an inch, so that its coated or prepared end will project beyond the periphery of the disk H. Immediately above said disk is placed aspring, K, which has its lower face roughened, and is placed at such distance from the periphery of the same as to cause it to ignite the fulminate upon the projecting ends of said matches as they are, successively,
brought into contact with it by the rotation of said disk, the flame from each match being suflicient to ignite the wick f immediately above.
The disk H is rotated by means of a lever,
L, which is pivoted at one end upon the stud 1o G-in rear of said disk-and projects downward through the bottom of the reservoir 1).
A spring-pawl, I, attached to and forming part of said lever, engages with any one of a series of teeth, h, which are formed upon the rear face of said disk, so that if said lever is moved forward and backward to the limit of its motion, said pawl will alternately engage with a tooth, h, and move said disk forward, and will pass backward overthe next succeeding tooth,
and as the number of said teeth corresponds to the number of the grooves h, each movement will cause one of the matches I to be brought to position and ignited. Backward movement of the disk H ispreventcd by means ofa detent, M, which is secured to or upon the reservoir D, and engages with the teet l h.
The end ofthe wick-tube F is inclosed, when desired, by means of an extinguisher-cap, F,
that is hinged at one end thereto, and is capa- 3o ble of being turned over said tube, as shown in Figs.3,5, and 7, or ofbeing turned away from the same, as seen in Figs. 4, 6, and 8. The
movements ofthe extinguisher F are rendered automatic by means of a rod orarm, l, which projects from the lever L upward into a loop,
f, that is provided upon the rear face of said extinguisher, by which arrangement the wick fis uncovered and rendered accessible to the flame ofa match at the instant said match is turned to position and ignited, while by returning said lever L to its normal position said extinguisher is caused to close over said Wick and to instantly smother the flame, said operations being carried on from without the lantern. 5
I am aware that it is not new to arrange matches radially within a pivoted disk, and to ignite said matches by rotating said disk, so as to cause the fulminating coatingot' the ends ofthe former to come into contact with a fric- 5o tion-surface.
I do not herein claim, broadly, an extinguisher-cap combined with the open end of a curved wick-tube, the same being the subject of another application.
Having thus fully set forth the nature and merits of my invention, what I claim as new 1s- 1. The rotating match-holder H, provided with radial grooves h, for the reception of matches, in combination with the spring friction-arm K, substantially as and for the purpose specified.
2. In combination with the match-holder H, provided upon one face with teeth h, and journaled upon the stud G, the lever L, pivoted upon said stud and provided with the longitudinal spring-arm l, which operates as a pawl, and at its side edge engages with said teeth h, and the spring-detent, secured to or upon a fixed support, and also arranged to engage with said teeth, substantially as and for the purpose shown.
3. In combination with the end of the wicktube F, the extinguisher-cap F, hinged thereto 7 5 and provided with the loop f, and the lever L, pivoted upon the stud G, and having a rod or arm, I, that engages with said loop, substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 8th day of August, 1879.
W. D. DOREMUS.
