OTTO F. W. PUERNER, OF GREEN BAY, WISCONSIN.

SAFETY DEVICE FOR LAMPS.

Specification of Letters Patent.

Application filed November 14, 1907.

Patented Aug. 11, 1908.

Serial No. 402,156.

To all whom it may concern:

Be it known that I, OTTO F. W. PUERNER, a citizen of the United States, residing at Green Bay, in the county of Brown and State of Wisconsin, have invented certain new and useful Improvements in Safety Devices for Lamps; and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to new and useful improvements in safety devices for lamps; and has for its object to provide 'a simple and efiiciently operating means of this character adapted to be applied to a lamp and sustained in an inoperative position when the lamp is in an upright or normal position, but should the lamp be inadvertently overturned or upset, operate to extinguish the light and eliminate liability of explosion or fire.

In the accompanying drawings,Figure 1 is a side elevation showing the application of the invention to a burner; Fig. 2 is a plan view of Fig. 1, the burner hood removed;

Fig. 3 is a detail perspective view of one of the extinguishing members, the same being represented on an enlarged scale.

Referring to the drawings for a more particular description of the invention, 1 indicates a burner of ordinary form comprising the usual base, table, and hood, 2, 3 and 4, respectively, the hood being hingedly connected with the base as usual.

In carrying out the invention, the table is perforated to provide for proper ventilation, and is provided with two central, parallel, upwardly extending spaced flanges 5, leaving a central opening 6 for the reception of the wick tube and wick, 7 and 8, respectively. Said table is also provided at its eriphery with a plurality of equally-s aced c epending apertured lugs 9, whereby t e table may be removably ositioned over the base by screws, or other equivalent fastening means, extended through the a ertures of the lugs and engaged with the ase. Said table is also split and bent at each end of its opening 6 .toform an upright extension or member 10, said member being disposed atrightangles to the plane of the flanges 7 and having an eye or aperture 11 at each end, the

- function of which will be disclosed.

The numeral 12 indicates an operating member, essentially comprising an oblique body 13, of approximately rectangular form,

having outwardly projecting extensions 14 at its inner corners, and being bent centrally of its ends to form a central depending supporting member 15, adapted to bear on the table and normally support the operating member in an inoperative position. Said operating member is also bent inwardly approximately at right-angles to form upwardly extending apertured ears or lugs 16.

In practice, an operating member is pivotally mounted on each side of the wick by its extensions 14 being engaged in the apertures 11 of the upright members or extensions 10.

The numeral 17 indicates the extinguishing members, each of which is in the form of a hood or casing adapted to entirely incase or inclose the upper end of the wick to extinguish the light, when the operating members are swung inwardly into operative posi tion by the lamp being inadvertently upset or displaced, each of said hoods or casings being formed from a single piece of metal, and of straight elongated form.

The end walls 18 of each of the casings or housings are also provided with inwardly projecting extensions 19, and in the application of the invention are arranged in position by their extensions being engaged in the apertures of the ears or lugs 16 of the operating members.

From the construction illustrated and defined, it will be readily perceived that should the lamp to which the invention is applied be inadvertently upset or overturned one of the extinguishing members will be caused to swing inwardly by its operating member over the lamp wick and extinguish the light.

I claim as my invention:

1. In combination'with a burner, the table of which is formed with an upright extension at each end of its wick tube opening, operating members pivoted between the extensions in position to swing toward and from the wick tube, each of said members having a dependingsupporting leg designed to normally bear on the table to maintain it in approximately horizontal or inoperative position and extinguishing members arranged at the free ends of the operating members, either of which will incase the upper end of the wick tube, should its operating member be caused to swing inwardly into operative or extinguishing position by tilting or upsetting the lamp.

2. In combination with a burner, the table of which is provided with an upright apertured extension at each end of its wick tube opening, operating members arranged in the burner on opposite sides of the wick tube, said members having extensions for engaging with the apertures of the burner head table extensions and depending supporting legs designed to bear on the table to normally maintain them in approximately horizontal or inoperative position, and an extinguishing hood arranged at the outer end of each of the operating members, either of the extinguishing hoods being adapted to incase the upper end of the wick tube should its operating member be caused to swing inwardly into extinguishing or operative position by tilting or upsetting the lamp.

3. In combination with a burner, the table of which is provided with upright apertured extensions at the ends of its wick tube opening, operating members arranged in the burner on opposite sides of the wick tube,

. said members having lateral extensions formed at their inner ends for engaging with the apertures of the extensions of the burner head table, having laterally space apertured ears at their outer or free ends and having portions bent to form depending supporting legs designed to normally bear on the burner head table to support the operating members in approximately horizontal or inoperative position, extinguishing hoods or members formed at opposite ends with inwardly extending extensions to engage with the apertures of the operating member ears, either of the extinguishing hoods or members being adapted to entirely incase the upper end of the wick tube should its operating member be swung inwardly into extinguishing or operative position by tilting or upsetting the amp.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

OTTO F. W. PUERNER.
