MANTLE-SLJPPORT.
SPECIFICATION forming part of Letters Patent No. 757,556, dated April 19, 1904.
Application filed February 2, 1904. Ltqerial No. 191,631. (No model.)
To all whom, it may concern:
Be it known that I, WILSON P. JOHNSON, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have inventedcertain new and useful Improvements in Mantle-Supports; and I do hereby 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. I
A great deal of expense and annoyance have been occasioned by the destruction of Welsbach mantles due to the softening andbending of the support for holding them.
The object of the present invention, therefore, is to provide a support in which this trou-.
.ble cannot occur; and the invention consists ing a horizontal portion 1 with a middle seat 1 l to receive the loop of the mantle and up- The upright portions are made each with a series of holes 1, througha horizontal pair of which is passed a rod 2, so that its ends shall project beyond the upright portions, as seen in Figs. 1 and 2.
When the mantle is in place in the frame, the ends of the rod 2 rest on the upper side of the top ring 3 of the frame, as seen in Fig. 1.
The bridge proper and the rod willpreferably be made of magnesia, clay, or other material refractory to heat. The bridge can be made of metal and the rod of the refractory material with good results; but in this event it will be desirable to cover the horizontal portion with asbestos, as indicated at 4 in Fig. 1.
Besides the advantages of adjustability and firmness of the support it will be observed that the light from the mantle in a horizontal or downward direction is not in any measure obstructed by the support.
. What I claim, and desire to secure by Letters Patent, is-
V 1. 1n amantle-support, the U-shaped bridge having perforated upright arms, in combination with a bar to engage the perforations of said arms and extend beyond the same.
2. Inamantle-support, the U-shaped bridge having a horizontal portion with a seatfor the loop of the mantle and perforated upright arms, in combination with a bar to pass through said perforations and project beyond the arms. v
In testimony whereof I aflix my signature in presence of two witnesses.
WILSON P. JOHNSON.
