TUBULAR LANTERN. 09,896. Patented Dec. 30,1884. i \5 llnrrnn "rn'rns PATENT Oriana.
ROBERT J. THOMAS, OF HOUL"ON, MAINE, ASSIGNOR OF ONE-HALF TO ALEXANDER R. RICE, OF BOSTON, MASSACHUSETTS.
TUBULAR LANTERN.
SPECIFICATION forming part of Letters Patent No. 309,896, dated December 30, 1884.
Application filed April 25, 1884. (No model.)
12 aZZ whom it may concern:
Be it known that I, ROBERT J, Tnonrs, of Houlton, in the county of Aroostook and State of Maine, have invented a new and useful Improvem'ent in Tubular Lanterns; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
My invention relates to that class of lanterns in which a concave disk is secured to the central tube of a continuous draft-tube, which latter forms the supporting-frame of the lantern; and the novelty consists in the construction, arrangement, and adaptation of parts, as will be more fully hereinafterset forth,
' and specifically pointed out in the claims.
The invention is designed as an improvement upon Patent, No. 244,944, of 1881, in which devices for raising, supporting, lowering, and securing the glole of a lantern were arranged to conveniently and speedily allow the filling, trimming, lighting, or extinguish ing of the lamp. In such construction, however, not only were the tubes which comprise the supporting-frame left standing in a vertical position, but, owing to such vertical vposition, the globe and its adjuncts-had to be supported by a spring-catch. This springcatch was necessarily providedwith two locking-shouldersone to hold the globe locked and the other to hold it elevated.
My invention contemplates hinging the draft-tube, to allow a portion of it to be lowered into ahorizontal position entirely out of the way of the operator. and by reason of such construction I avoid the necessity for locking the globe in an elevated position, as well as the necessity for elevating such globe to any distance beyond its point of contact "with the cone of the burner.
The invention is fully illustrated in the accompanying drawings, in which Figure 1 is an elevation of a lantern embodying my invention, and showing the globe and supporting-frame locked in position for use; and Fig. 2 is a perspective view of the lantern, showing the globe and supporting-frame lowered.
Referring to the drawings, A designates the oil-reservoi r, having the usual burner and cone, (1; B, the globe, and Q the movable frame supporting such globe, andhaving the concave disk c,'whic-h is provided with a spring, 0, and the perforated plate (I.
F designates the horizontal portion of the drafttube, which is rigid with the oil-reservoir; and F, the remaining portion of said tube. tion, except that the part F of the draft-tube is loosely jointed with the part F thereof by one of the parts telescoping with the other, one part being provided with locking-pins, as and the other with corresponding recesses, as g. The material of the frame F allows its lower arms to be spread sufficiently to disengage these locking devices 9 g, and
the arms 0 of the frame 0 serve to hold the said locking devices together when the frame F is in avertical position.
It will be observed that it is only necessary that the globe and its frame should beheld into proper relation with the burner for use, and that it is only necessary to elevate the same sufiiciently to allow the plate (I to clear the cone of the burner in order to lower the entire frame and globe out of the way.
I have shown a spring-catch, i, for holding the globe down upon its seat, but this catch is not necessary for holding the globe at any point of elevation.
I attach importance to the construction whereby the folding portion of the frame is connected with the rigid portion thereof by a duplex telescopic joint. This allows the parts to be readily put together in the first instance, and as readily separated as occasion may require. It also forms an enlarged bearing and durable joint.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. Ina lantern, substantially as described, a tubular frame made in two parts, as F F, removably joined to each other by a telescopingjoint upon either side of the burner, the part F being rigid with the reservoir, and
These parts are of ordinary construe the part F being adapted to turn freely upon said rigid part to form a hinge, as set forth.
2. In combination with the draft-tube, coni This specification signed and witnessed this 7th day of April, 1884.
sisting of the parts Fand F, loosely conneot- ROBERT J. THOMAS. 5 ed together by a telescoping joint, a movable V globe-frame having looking-arms G, and en- \Vitnesses:
gaging locking means, as g, substantially as I GEO. S. GENTLE, and for the purpose set forth.
