OF NEIV YORK, N. Y.
TUBULAR LANTERN.
SPECIFICATION forming part of Letters Patent No. 476,478, dated J' une 7, 1892.
Application filed November I8, 1891. Serial No. 412.271. (No model.)
To aZ whom, t may concern:
Beit known that I, WARREN MCARTHUR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tubular Lanterns, of which the tollowing is a specification.
This invention relates to a tubular lantern in which the globe is mounted in a frame which can be moved vertically in the tubular lantern-frame for the purpose of exposing the burner for trimming and lighting the wick, SC.
The object of my invention is to provide a simple device wherebythe globe-frame can be easily raised and lowered and held in either position.
In the accompanying drawings, Figure l is a front elevation ot a tubular lantern provided with my improvement and showing the globe in its normal lowered position. Fig. 2 is a vertical section thereof in line fr, Fig. l. Fig. 3 is a sectional elevation of the top portion of the lantern, showing the position ot' the parts when the globe is in a raised position. Fig. 4 is a sectional elevation ot the top portion ot' the lantern, showing a modified form of the lifting device.
Like letters of reference refer to like parts in the several figures.
A represents the base of the lantern; B, the air-chamber; C, the burner; D, the upright portions of the air-tubes; d d, the lower and e e the upper horizontal branches thereof, and E the central depending tube, forming together the rigid tubular lantern-frame.
F represents the perforated plate, which surrounds the burner and upon which the globe G rests.
II represents the bell arranged above the globe and made vertically movable on the depending' tube. The bell and globe-supporting plate are connected by upright wires h h, which pass through guide-loopsz',secured to the upright portions of the tubes. The globe is firmly held upon the supporting-plate F by a spring J, secured to the bell. The perforated plate, the bell, and the upright wires form the vertically-movable frame in which the globe is mounted. All of these parts may be of any ordinary or suitable construction.
K represents an upright link, which is pivotally secured with its lower end to the upper side of the bell by an eye r. and extends upwardlyand backwardl ytheret rom toward the central tube.
L represents an n pright link arranged above the lower-link K and pivoted with its upper end to an eye Z, secured to the central tube near its top. This link is pivotally connected with its lower end to the upper end of the lower link. Upon swinging the upper link upwardly the globe-frame connected therewith by the lower link is raised from the burner, and upon swinging the upper link downwardly the globetrame is lowered upon the burner. lVhen the globe and its frame are in their normal or lowered position, the point of connection between the two links lies in the rear ofa straight line drawn through the fulcra of the two links. Any upward pressure applied to the globetrame, therefore, presses the connected ends of the links against the central tube, whereby the links are caused to resist the upward movement ot the globe-frame, thus securely holding the globe-frame in position upon the burner.
Then the globe-trame is in its raised position, as represented in Fig. 3, the upper link rests upon the top of the central tube and is supported thereby, and the pivotal connection between the links lies backward of the fulcrum of the upper link, thereby preventing the latter from being swung downwardly by the weight of the globe and its frame and holding the globe-traine securely in its elevated position. By this arrangement of the links with the central tube, which operates as a stop, a perfectly-reliable locking device is formed, whereby the globe-frame is easily manipulated and securely held either in a raised or lowered position.
The links are preferably formed of wire for economy in construction, but may be stamped out of sheet metal,it' desired. The upper link is preferably provided with a thumb-piece m, which permits it to be conveniently manipulated and which may be formed by bending a portion of the link outward, so as to form a big-ht, as represented in FigsZ and 3. If desired, the thumb-piece may be formed on the lower link, as represented in Fig. 4.
IOO
l Claim as my invention-- l. The eombinationvith the lautern-frame and the vertically-movable bell `sguided upon the central tube of the lantern-frame, of an upper link pivoted with its upper end to the lantern-frame and a lower link pivoially Connecting the lower end of the upper link with the bell, substantially as set forth.
2. The combination, with the lantern-frame and the vertically-movable globe-frame, of :in upper link pivoted with its upper end to the lantern-frame, n. lower link pivotnlly connecting lche lower end of the upper link with the upper end of the globe-fralne, and e thumbpiece formed on one of said links, substantially als set forth. r
3. The oonlbinatiolnwith the lantern-frame and the vertically-movable globe-frame, of an upper link pivoted wirh its upper end to the lantern-frame and resting thereon when the globe-frame is raised and L lower link pivota-llyeonneeting lche upper link with the upper end of the globe-frame, whereby lhe globefrmne is held in :t raised position, substantially as set forth.
4. The Combination, with the lantern-frame and the vertically-movable globe-frame, of an upper link pivoted with its upper end to the lantern-frame and a. lower link pivotally e011- neet-ing the upper link with the upper end of the globe-frame, both links being arranged in front of the depending tube of the frame and resting,` against the saine in the lower position of the globe-frame, substantially as set forth.
5. The Combination, with the lantern-frame and the globe-frame capable of Vertical movement on the upper portion of the lanternfralne, of :in upper link pivoted with its upper end to the lantern-frame and resting thereon in its elevated position and a lower link oonneebing the free end of the upper link with the globe-frame and resting against the lantern-frame in the lower position of the globefrmne, substantially as set forth.
lVitness my hand this 7th day of November, 1891.
NARREN MCARTHUR.
