SPECIFICATION forming part of Letters Patent lvm-756,994, dated April 12, 1904. Application ileil August 3, 1903. Serial No. 16.8,.07'7. (No model.)

To all whom, it may con-cern:

Be it known that ROSE LEwEs VALLEEN, a citizen of the United States, residing at Seattle, in the county of King and State of Vashington, have invented a new and useful Lamp- Chiinney, of which the following is a specification.

This invention relates to lamp-chimneys; and one of the objects thereof is to provide a cheap, durable, and eflicient chimney which will permit of expansion and contraction due to the caloric influence exerted by the surrounding atmosphere and prevent the breaking of the chimney on account of the sudden change in the atmospheric conditions in the immediate vicinity thereof.

A further object of the invention is to provide a sectional chimney the sections of which can readily be removed, so as to facilitate packing the same.V

A further object of the invention is to provide means for locking the sections together', so as to hold them upon the lamp.

Further objects, as well as the novel details of construction, will be specifically set forth in the following description, reference being had to the accompanying drawings, in which- Figure l is a perspective view of the chimney complete. Fig. 2 is a horizontal sectional view through the same. Fig. 3 is a fragmentary perspective view of the two sections detached, and Fig. 4 is a top plan View of the two sections ready to be packed.

The chimney, as illustrated, comprises two sections l and 2, each having staggered edges 3 and 4f, formed by a portion of each edge being offset, but parallel with relation to the remaining portion, to provide overhanging projections on one of the sections and supporting-shoulders on the other section. The two portions of each edge of each section are connected by an intermediate portion having an inclined edge 5 disposed at such an angle to the parallel edges as to form a tongue coinciding with a complementary tongue on the adjacent edge of the other section, so that the tongues can be brought into interlocking engagement with each other, whereby the sections will be held together. The tongues on the respective sections are oppositely disposed, so as to insure the proper engagement, and they are arranged so that the tongues on one section will constitute a support for those of the other section. The section 1 has each of its longitudinal edges preferably formed with a double bevel to provide the inverted- V-shaped edges, and the offset portion thereof is disposed near its top with the overhanging shoulder 5, inclined downwardly. The section 2 has each of its side edges provided with a V-shaped groove to receive the beveled edges of section l, the offset portion of section 2 being formed below the top thereof, beginning where the offset of section l terminates, and the shoulder 5 thereof being inclined upwardly to form a seat for the overhanging shoulder 5 of section 1,the edges of these shoulders being provided, respectively, with a V-shaped groove and an inverted-V-shaped projection. As the temperature within the chimney rises the expansion of the chimney will be permitted by allowing the sections to move apart at the abutting edges of the sections, and as soon as the temperature falls the chimney will contract, and the edges will come together. It will be seen that the expansion and contraction'may take place to a considerable degree without detriment to the chimney. Another advantageous feature is that the sections can be placed one within the other in packing, thus requiring but little space therefor.

I claim- 1. A lamp-chimney comprising two sections,

one of which is provided with convex longitudinal edges and the other with grooved edges, one of said sections having odset portions formed near its upper end on its longitudinal edges to form overhanging projections, and the other section having offset portions spaced from the top thereof with the terminals thereof inclined upwardly to form seats to receive said overhanging projections of the other section. l

2. A lamp-chimney comprising two sections one of which has the longitudinal edges thereof reversely beveled to form inverted-V-shaped projections, and the other section having its longitudinal edges provided with V-shaped grooves, one of said sections having an over- IOO hanging projection and the other section having an upwardly-inclined shoulder forming a seat to receive said projection.

3. A lamp-chimney comprising two sections one of which has oiiset portions formed near its upper end on its longitudinal edges to form overhanging projections, and the other section having offset portions spaced from the top thereof with the terminals thereoil inclined upwardly to form seats to receive said IO overhanging projections of the other section.

In testimony that I claim the foregoing as my own I have hereto aHiXed my signature in the presence of two witnesses.
