Description
UNITED STATES PATENu(Termec WILLIAM H. BARNARD, OF SEDALIA, MISSOURI.
IMPROVEMENT IN LAM P-CHIMNEYS.
Specification forming part of Letters Patent N0. 165,912, dated July 27, 1875; application led January 4, 1875.
To all whom it may concern:
Be it known that I, WILLIAM H. BARNARD, of Sedalia, in the county of Pettis and State of Missouri, have'invented certain new and useful Improvements Ain Lamp-Chimneys, of which the following is a specification My invention relates to certain improvements in that class ot' lamp-chimneys which are constructed ot' two longitudinal sections, united at their edges, and properly bound or clasped together, for the purpose of allowing for the expansion and contraction ofthe glass when subjected to sudden changes of temperture, and preventing the chimney from cracking or breaking.
rlhe object of my invention is to secure a more perfect joint at the point of union of the two sections, and provide a more secure and reliable device for binding the two sections together,than has been heretofore accomplished in the chimneys of this class, as ordinarily constructed; and my invention consists in constructing a chimney of two longitudinal sections or parts, as usual, each section having a longitudinal lange on its edges, which imite and form a longitudinal projection or edge on the outside of the chimney when the sections are bound together.
By this construction a broad face is obtained along the edges of each. section, which form, when properly ground and placed together, a perfect joint.
In the drawings, Figure lis a perspective View of my improved lamp-chimney; Fig. 2, a similar view ot' the same with the end ferrules removed. Figs. 3 and 4 are detached views of the top and bottom ferrules, respectively', and Fig. 5 is a section on line a; cof Fig. l.
The letters A A represent the sections composing the chimney. Along the edges ot' each section, on the outside, a longitudinal ilange, d, is formed. The faces of these ilanges are accurately ground, so as to form a per- Y fectly tightjoint when the sections are joined together. rlhe anges do not extend quite to the end of the sections, but terminate a short distance from said ends, in order to allow the sections to set into the annular t'errules which bind them together. These annular ferrules are represented by the letters B B. 'llhey are constructed so as to grasp the edges of the sections at their ends, both on the inside and outside, and thus irmly bind them together.
It will be seen that by the ,abo\'e-descrbed construction of the sections a broad face will be formed along the edges ot' the sections at the point of union, which will allow said edges to be readily and accurately ground, forming a perfect joint throughout the entire length ot' the sections, which it has hitherto been found impossible to obtain.
The annular i'errules, by grasping both the outside and inside of the chimney, will prevent any slipping' of the sections, and thusV necessarily bind them in place.
The chimneys thus constructed are `admirably adapted for packing for transportation, as the sections will nest together, occupying but little room. i
Having thus described my invention, what I claim as new, and desire to secure by Let- A lamp-chimney constructed of two sections, each of which is provided with laterally-projecting flanges, substantially as described, whereby, when the sections are placed together, a longitudinal projection is formed and a perfect joint secured, as set forth.
In testimony that I claim the foregoing I have hereunto set my hand and seal.
WILLIAM H. BARNARD. [L. s]
