' NITED STATES PATENT OFFICE.
.IOI-IN GUNNING, OF PHILADELPHIA, PENNSYLVANIA.
LAM P-CHYIIVINEY PROTECTOR.
SPECIFICATION forming part of Letters Patent No. 551,859, dated December 24, 1895.
' Application filed April 3, 1895. Serial No. 544,225. (No model.)
To all whom it may concern.-
Be it known that 1, JOHN GUNNING, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Lamp- Chimney Protectors, of which the following is a specification.
The principal objects of my invention are, first, to provide an efficient, simple, durable and comparatively inexpensive device adapted to meet requirements and perform the functions of a lamp-chimney protector; second, to provide a lam p-chimney protector with a frame, support or body of copper or other metallic substance or material and a slab,
- disk, plate or wrapping of asbestos or other heat-non-conducting material held in or on said frame and adapted to occupy a position within the chimney above the flame; and, third, to provide a lamp-chimney protector consisting of a blank of copper or other suitable metallic substance stamped into required shape or form to receive the asbestos and provided with arms adapted to rest on the top of the chimney and to support the asbestos above the gas, oil or other flame.
My invention consists of a lamp-chimney protector constructed and arranged in substantially the manner hereinafter described and claimed.
The nature, characteristic features, and scope of my invention will be more fullyunderstood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure 1 is a front elevational view of a lamp-chimney, illustrating a protector embodying features of my invention suspended within the chimney from the top rim thereof. Fig. 2 is a perspective View, enlarged, of the protector illustrated in Fig. 1, the frame or body thereof consisting of a piece of wire coiled and covered with asbestos or other heatnon-conducting material. Fig. 3 is a top or plan view of the supporting wire frame or body flattened out for the reception of the heat-non-conducting material constituting the protector of Fig 2. Fig. 4 is an enlarged perspective view of a modified form of the protector, illustrating a metal strip or blank covered with asbestos held in place by a copper strip or band and rivet. Fig. 5 is a top or plan view of a blank flattened out, forming the supporting frame or body of the protector illustrated in Fig. 4:. Fig, 6 is a perspective View of a further modified form of the protector in which a slab of asbestos or other heatnon-conductin g material is held in a flame and is supported by a blank provided with retaining and supporting arms; and Fig. 7 is a top or plan view of the blank flattened out, constituting the frame or body of the protector illustrated in Fig. 6.
Referring to the drawings, a represents the lamp-chimney, and b the upper rim or edge thereof. From this rim or edge I) are suspended the metallic arms 0 and a, bent respectively at d and d to fit around the rim or edge I) of the chimney a. The arms 0 and 0 project downwardly within the chimney a and terminate in a body, frame or base c of metal, onto which asbestos or other heat-non-conducting material f is mounted or supported.
In the form illustrated in Figs. 1, 2, and 3 the frame, body, or base 6 and the arms 0 and o are formed of a single piece of wire, preferably copper, bent and coiled as illustrated in Fig. 3 of the drawings. Around the coiled portion or frame e is wrapped asbestos or other non-conducting material f, which is held in place by a strip or band g of metal, preferably copper, secured thereto by means of a rivet 7L, passing through the strip g, the asbestos f, and the opening 2' in the body or frame 6, substantially in the manner illustrated in 2 of the drawings.
In the modification illustrated in Figs. 4 and 5 the arms 0 and c are integral with the metal body or frame 6, the arms and body or frame being stamped or sheared out of sheet metal, preferably copper, because, as practice has demonstrated, this metal is adapted to withstand a high heat without melting or fusing; and, moreover, aprotector such as described and constructed as explained is especially adapted for the chimney of the WVelsbach type of lamp, in which the flame thereof is brought to a high state of incandescence and without fear of breaking the chimney, while the device of my invention is suspended therein above the inflamed mantle of such lamp. This is due to the fact that the more or less intense heat arising from the flame of the lamp is attracted toward the center thereof to the said body, thereby allowing the products of combustion or heat arising from the flame of the lamp to escape around and through the passage-way formed between the said body and wall of the chimney in volume from the top thereof unobstructed in any manner, thus greatly lessening the tendency to breakage of the chimney. It may be here remarked that the cooler portion of the chimney is next to the wall thereof and the hotter portion about the said body, whereby effective working, as extended practice has demonstrated, is insured. In the above form of the device the asbestos or similar substance is wrapped around the frame or body e and secured thereon by a copper strip or band g, riveted thereto in a similar manner as illustrated in Fig. 2, the rivet h passing through a central opening 1 in the frame or body 6 of the metal blai'lk.
In the modification illustrated in Figs. 6 and 7 the frame or body 6 and arms 0 and c are integral, being stamped out of sheet metal, preferably copper. In this form the frame is provided with preferably four prongs or fingers 7a, and the asbestos is to be placed on the under face of the frame 6 and lapped around into the upper face and retained therein by bending down the series of prongs or fingers 70 upon the asbestos and introducing the rivet it through the free end portion of the series of fingers and the body of the frame 6 as illustrated in Fig. 6.
I11 operation the protector is suspended by the arms 0 and c from the upper edge or rim 1) of the chimney a. The frame or body, with its asbestos covering, disk or plate I), is suspended within the chimney a, directly over or above the flame.
It is here remarked that it is preferred to make the arms and frame or body of the pro teeter of copper, as that metal will sustain a much greater heat before melting or fusing than most other metals that have been experimented with for the purpose of 111 y inven tion. Instead of copper, however, soft steel. or other metal capable of sustaining an intense heat without melting may be used without departing from the spirit of my invention.
Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A lamp chimney protector, consisting 01. a blank having integral supporting arms bent upward and outward and terminatin in downwardly projecting clips, heat non-conducting material applied to said blank and banded thereto and secured by a rivet, substantially as described.
2. A lamp chimney protector, consisting of a blank having integral supporting arms bent upward and outwaml and terminating in downwardly projecting clips, said blank also provided with fingers or prongs for retaining asbestos or the like in connection with said blank and secured by means of a rivet, substantially as described.
In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.
.TOIIN GUNNING.
