IMPROVED CONE AND CHIMNEY ELEVATOR.

Specification forming part of Letters Patent No. 42.045, dated March 22, 1864.

To all whom it may concern.-

Be it known that 1, WILLIAM R. P. ORoss, of Portland, in the county of Cumberland and State of Maine, have invented a new and Improved Lamp Gone and Chimney Elevator; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a perspective view of my improved burner or lamp-cap, showing the cone resting in its place within the cap. Fig. 2 is a perspective view of the same, showing the lampcone in an elevated position. Fig. 3 is a vertical diametrical section through the burner or cap and cone, the latter being represented in an elevated position.

Similar letters of reference indicate corresponding parts in the three figures.

It is frequently a source of annoyance to persons using the coal-oil or other hydrocarbon lamps that the wick cannot be conveniently trimmed after the la mp has been lighted and the parts have become hot. The

object of my invention is to remedy this evil by a very simple and cheap attachment to the common burner, which will enable any person, by a simple manipulation, to raise the lamp cone and chimney above the burner, and at the same time move these parts to one side of the center of the burner, so that the wick can be conveniently trimmed, or the wicktube cleaned without detaching the chimney or the cone from the cap of the lamp, as will be hereinafter described.

To enable others skilled in the art to make and use my invention, will proceed to describe its construction and operation.

In the accompanying drawings, 0. represents a common coal'oil lamp-cap b, the adjustable wick-tube; c, the scalloped rim within which the seat for the cone d is formed; and e f are the common fastenings for securing the chimney to the ribbed flange or base of the cone. All of these parts may be constructed in any of the well-known forms, and still my invention is applicable to any of them.

A bow-shaped piece of metal, 1', is attached to the rim of the cone d by means of a hinge or pivot, which will allow the bow to work freely, and the extreme ends of this hinged bow are bent so as to form pivots, byineans of which the bow is attached to the sides of the lamp-cap a, as shown in Fig. 2. The length of this hinged and swinging bow is such that it will allow the cone to fit snugly within the scalloped rim 0, as shown in Fig. 1, and to be put into its seat and removed therefrom by a swinging motion. This bow forms the connection between the cone and burner, and serves as an inner support for the cone when it is in the elevated position represented in Figs. 2 and 3.

A curved rod, 9, is pivoted to the base of the cone d at a point which is diametrically opposite to the hinge-connection of the bow t with this cone. This rod 9 is passed down through a hole in the perforated cap a, and has a thumb-button, it, formed on its end. The length of this rod g with respect to the bowz' is such that when the cone d is elevated and brought to the position indicated in Fig. 3-viz., a horizontal positio.n-'-the button It will touch the lamp-cap and form a stop for the rod 9, and the arms of the bow will stand in a position which is slightly inclined from a perpendicular line to the base of the lamp. Thus it will be seen that these hinged rods form legs for supporting the cone and the chimney, if attached to it, when the parts are elevated, and the single rod 9 serves also as a means whereby the cone can be raised and moved to one side of the center of the lampcap at one and the same movement of the finger.

When the cone is elevated, it will be seen that the rod g, bearing on the edge of the cap a, will form a rest at this point, which keeps the parts in this position until the rod g is drawn downward and outward, which operation returns the cone to its seat on the cap on, leaving this rod 9 projecting from the cap, as shown in Fig. 1. The movement of the rod 9 in elevating the cone is upward and outward, and it being longer than the legs of the hinged bow t', the cone is moved on one side 'of the wick tube a sufficient distance to allow the wick to be easily trimmed. Another advantage in the use of the curved rod 9 is that when the cone is seated in its place on thecap a the button 70 is so remote from the flame or heat of the lamp that it is always cool, or not sufficiently hot to burn the fingers.

It may be found desirable to attach the bow-support 1: outside of the cap a. If so, the ends of its arms are bent inward, instead of outward. It will then fall outside of the rim 0 but when arranged as described and shown this bow will not be seen when the cone is in its seat. So, also, may the lever g be arranged to be entirely within the cone and burner, when the chimney is notin an elevated position,by simply shortening the lever g and having this lever hinged to and within the burner and the stop end of the burner work through an eyebraeket within the cone. In this case the cone and chimney will be wholly manipulated through the button that retains the chimney in place.
