JAMES H. HILL, OF ROCHESTER, NEVJ YORK, ASSEGNOR T0 DEFIANGE LANTERN 86 STAMIING (30., OF ROCHESTER, NEW YORK LANTERN.

To all whom it may concern:

Be it known that I, JAMES H. HILL, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Lanterns; and I do 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, reference being had to the accompanying drawings, and to. the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to lanterns, and more particularly to means for lifting the globe and holding or securing it while in its raised position. v

It has for its object to provide at the throat of the elbow of the air tube, at the oil font, a bearing and lock for the lever employed for lifting. the globe, said bearing having at its upper end an eye for the passage of the lever journaled therein and also a hook-portion spaced fromthe air tube to leave an opening between said portion and the tube for the passage of the locking lever, said hook portion being formed with a notch or recess to receive the lever and adapted to lock the lever when depressed to raise the globe, said lever being under the influence of a spring exerting a downward pressure on the globe and serving to hold the lever in the locking hook when the lever is depressed and also to hold it against the bearing when the lever is in its normal position above and to one side of the hook when the globe is down or seated.

It has also'for its object to so form and apply said bearing-piece that it will bear against the vertical portion of the air tube and rest upon its horizontal portion at the throat of the elbow thereby giving the maximum rigidity and strength to the bearingpiece as well as bracing the air tube at its elbow.

To the accomplishment of the foregoing and such other objects as may hereinafter appear'the invention consists in the features hereinafter particularly described and then sought to be clearly defined by the claims, reference being had to the accompanying drawings forming a part hereof, and in which Figure 1 is a front elevation of a lantern Patented Mar. 9, 1915,

with the improvements applied thereto, a portion of the dome being broken away; Fig. 2 is a side elevation, and showing in dotted lines the position of the parts when the globe is raised. Fig. 3 is a section on line 33 of Fig. 1, on an enlarged scale.

In the drawing, the numeral. 1 designates the oil font; 2 the air chamber; 8 the air tubes; 4 the globe plate; 5 the dome; 6 the spring for holding down the globe; and 7 thelifting lever to which the globe plate is hinged, which parts may be of any well known approved pattern.

The lifting lever 7 isjournaled at one end in a bearing plate 8 which is angular in cross section by having theflange 9 bentat right angles to the body portion 10. The flange 9 is formed with an eye or opening 11 near its upper end for the passage of the lifting lever which at that point is bent to form a crank arm 12. The upper part of the bearing plate 8 is formed with a hook or head 13 which extends in the direction of the adjacent air tube 3 but terminates at a point distant from the tube so as to leave an open space 14. .between it and the air tube through which the crank portion of the lifting lever may pass when depressed for the purpose of lifting the globeplate and its globe. The hook or head 13 is formed with a notch or recess 15 in which the lever-crank may enter when depressed and which will lock the lever in place so that the globe and its supporting plate will be held in their raised position against the tension of the spring 6 which exerts a downward pressure on the globe. The spring 6 exerts an inward tension on the lifting lever so as to draw or pull the crank of the lever against the portion of the flange 9 in front of the hook or head 13 when the crank is raised and the other part of the lever with the globe is lowered and thus the parts are firmly held. When the crank is depressed so as to lift the globe and its plate against the tension of spring 6, the crank glides over the head or hook and passes between it and the air tube, and the tension of the spring 6 draws the crank into the notch or recess and holds it therein under a spring tension so that it is locked in position to hold the globe raised and under a steady pressure. The bearing plate is rendered strong by reason of its angular cross section shape, and it is fitted in the throat 15 formed by strength of the parts, the portion of the bearing .plate next to the air tube is formed with a laterally extending clip or ear 16 which fits in a correspondingly"shaped opening formed in the air tube and is soldered or may be brazed thereto, thus closing the cut-out portion of the tube, the top and bottom walls or'edges of which constitute abutments for the top and bottom edges of 1 the lip or ear, and thus guard against the lip'being displaced and consequently add to the strength and stability of the parts. The opposite end of the lifting lever is journaled in a bearing plate 17 likewise .made angular in cross section by having the flange 18 bent at right angles to the portion 19, said plate being set in the throat of the elbow and secured to the vertical as well as to the horizontal portions of the air tube V by soldering or otherwise. The flange 18 is formed with an eye 20 for the end of the lifting lever, and the plate may be formed with an ear or lip 21 fitted in and secured to the air tube in the same manner as the other bearing plate although it is not so necessary as there is not as much strain at this end of the lever as at the crank or operating end.

By journaling the operating end of the lever at the upper end ofthe bearing-plate and providing thelocking hook at the same end the area of sliding contact between the lever and the bearing-plate in movement of the lifting lever is reduced to the minimum thus lessening the wear on the parts and prolonging their life as the point of contact is practically along only one side or edge of the hook or head. It also'makes it unnecessary to provide a separate locking feature for securing-the lever in the position it bears when the globe is lowered and to hold the globe steady in its lowered-position because the spring which depresses the g obe holds'the latter steady and also secures the lever in its normal position since the tension of that spring exerts its influence on the lever, so that in effect the lever in its lifting operation acts against or in opposition to the globe depressing spring and is held in itslocking recess by theretractile tensionof said spring. The advantage of the other features of construction have been set forth in describing their construction and application.

Having described my invention and set forth its merits, what Iclaim'is': V la'ln a lantern, the combination with the airtubes,globe-plate, globe, spring for boldsecure the globe in an elevated position against the tension of said spring, substantially as described.
