TUBULAR LANTERN.
[Application filed Jan. 5, 1900.)
(No Model.)
rrnn TATES FREDERICK DIE'IZ, OF NElV YORK, N. Y., ASSIGNOR TO THE R. E. DIETZ COMPANY, OF SAME PLACE.
TUBULAR LANTERN.
SPECIFICATION forming part of Letters Patent No. 655,328, dated August 7, 1900.
Application filed January 5 1900. Serlalll'o. 414. (No model.)
To all whom it may concern:
Be it known that I, FREDERICK DIETZ, a citizen of the United States, and a resident of New York city, inthe State of New York, have invented new and useful Improvements in Tubular Lanterns, of which the following is a specification.
This invention relates to the lifting devices which are employed in tubular lanterns for raising and lowering the globe. In this class of lanterns the plate on which the globe rests is usually so mounted in the lantern-frame that this plate can be raised from the burner for giving access to the latter for lighting, &c. The lifting device which is employed in connection with sucha globe-plate for raising and lowering the same is usually provided with a lifting-lever, which is arranged on the lower portion of the lantern-frame, and a device for locking the lever in its raised and lowered positions, so as to hold the globe-plate either raised or lowered. Lifting devices of this kind are shown, for instance, in Patent No. 498,045, dated May 23,1893, to Wright, and in Patent No. 507,706, dated October 31,1893, to Bergener. The lifting-lever is usually formed of wire and can be bent out of shape and so be rendered unserviceable by attempting to turn it in the wrong direction. This occurs occasionally when the lantern is manipulated by persons who are not familiar with such lifting devices. p
The object of my invention is to construct the lifting device in such manner that the lifting lever is so confined and guided in either position that it cannot be moved in the wrong direction in swinging it out of its raised or lowered position.
In the accompanying drawings, Figure 1 is a front elevation of the lower part of a tubular lantern provided with my improved lifting device, showing the globe-plate raised. Fig. 2 is a side view of the same. Fig. 3 is a perspective view showing the globe plate lowered.
Like letters of reference refer to like parts in the several figures.
A represents the oil-pot; B, the air-chamber, secured to the top thereof; 0, the burner, resting on the air-chamber; D, the lower portions of the air-tubes, and E the globe-plate.
All of these parts may be of any ordinary or suitable construction.
F represents the bent lifting-shaft, which is arranged transversely in the lantern-frame below the globe-plate and connected with the latter. This shaft is formed with journals f, which are arranged in bearings g, projecting from the rear sides of the air-tubes. By turning the shaft in its bearings the globe-plate is raised and lowered.
His the lifting-lever, which is formed at one end of the shaft F, preferably in one piece therewith, as shown, by bending the shaft and lover out of one piece of wire. This lever extends from one of the journals f of the shaft past the outer side of the adjacent air-tube and terminates on the opposite or front side of this air-"tube in a thumb-piece h.
I represents a slotted guide which is secured in an upright position to the outer side of the air-tube adjacent to the lifting-lever and through which the latter passes. This guide is provided with an outer bar 2 and an inner bar 70, which are separated by an upright slot Z, in which the lever plays. This slot is closed at its upper and lower ends, so
that the lever is confined within the slot. The slot is provided at the upper and lower ends of the inner bar It with depressions m a, respectively. The lever is held snugly against the inner bar by the spring action of the bent shaft, which tends to draw the lever toward the air-tube.
In Fig. 3 the globe-plate is shown in its lower position, and the lever projects upwardly and forwardly from its fulcrum and is seated in the upper depression m of the slotted guide, thereby holding the globe-plate in its lower position. As the guide is closed at the top, it confines the lever and prevents the same from being moved upwardly or in the wrong direction, but allows the lever to be sprung out of the depression m and to. be moved downwardly when it is desired to raise the globe plate. When the lever reaches the lower depression n,'itsprings into the same, and thereby holds the globeplate in its raised position, as represented in Figs. 1 and 2. When the lever is in its lower position, it is confined by the closed lower end of the slotted guide against movement in a downward direction. It is therefore impossible to move the lever out of either position except in the proper direction, and the improper manipulation and consequent disarrangement of the lifting device are thereby rendered impossible.
The slotted guide is provided on one side with a base-flange p, which is secured to the outer side of the adjacent air-tube by soldering.
I claim as my invention 1. In a tubular lantern, the combination with the air-tubes, the vertically-movable globe-plate and the transverse, bent, liftingshaft connected therewith and provided with a lifting-lever, of an upright guide which is secured to the air-tube adjacent to the lifting-lever and which is provided with a slot which is closed at its upper and lower ends, in which slot said lever is guided and con- Witness my hand this 29th day of December, 1899.
