Erw/1 wijf/1406020 f' ITE Tnrns ERNST A. EVERSMAN AND DANIEL WAGNER, OF TOLEDO, OHIO.
HOT-#MR PIPE.'
-SPECIFIIZCA.513mm' forming part of Letters Patent No. 425,601, dated April 15, 1890. Application filed December 10, 1889. Serial Nol 333,186. (No model.)
r To atl whom. it may concern:
' States, residing-at Toledo,
companying drawings.
Beit known that we, ERNST 4A. EvERsMAN and DANIEL WAGNER, citizens of the United in theV county7 of Lucas, State ot Ohio, have invented certain new and'useful Improvements in Hot-Air,
,Pipes, of which the following is aspeciiication, reference being had therein to the lac- This invent-ion has relation to certain newy andusefulimprovements in hot-air pipes of that class composed of inner and outer walls With a passage-Way between the same, and is designed more especially as an improvement upon the pipe shown in Patent No; 411,652, dated September 24, 1889, granted to us; and
.ithasfr its @bien .t provide, animpwvd.. pipe of this character, which, when several sections are united, constitutes a very solid shaft Without rivets and Without solder, being anabsolute protection to the wood-work and laths in a partition. We aim at ease and cheapness of manufacture. The inner wall of one section is bent at right angles to the length of the section and thence parallel with the outer wall, which is bent over the lower end of said inner wall. The adjacent section,
' and consequently the other end of the aforementioned section, has a separate piece passed over the top and embracing the inner and outer wall, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claims.'
- The invention is clearly illustrated in thel accompanying drawings, which, with the letters of reference marked thereon, forma part of this speciication, and in which.`
Figure 1 is a vertical section through two vsections of pipe constructed in accordance l with our invention, united to forni a continuous shaft. Fig. 2 is an end view of one of the sections, and Fig.2 is an enlarged-Vertical sectional detail of the adjacent end of two sections.
Like letters of reference indicate like parts throughout the several views.
- Rejeging to the details of the drawings by letter, A designates sections-of the-pipe, each composed of an inner wall A and an outer l wa1lA2. At one end the inner wall is bent inward, as at c, to form a horizontal portion or shoulder to rest against the upper end of the next lower section of pipe, and thence bent downwardly, as at a', parallel with the main portion of the inner wall, the said portion d being adapted to t within the upper end of the next lower section. The inner wall is then bent horizontally, as shown at a2, and thence again downwardly, as at a3, the horizontal portion being provided with a plurality of openings a4. The outer Wallv A2 of this section at this end is bent inwardly, as at a5, forming a horizontal .portion and shoulder, and thence in the direction .of the length of the section and under and upon the inner side of the portion a3 of the inner wall, tightly embracing the same at the end and upon, twg sides, as clearly shown in Fig. The oppositeu end of this section has its inner wall extended a short distance beyond the end otits-enter wall, and a lseparate piece of metal B ispassed over the ends of the inner and outer walls, being bent to embrace the endsof both said inner and outer walls, as vshown at B in Fig. 3, being bent upon the insideof the inner Wall, as at b, to correspond withand of substantially the the portion a. of the opposite end, and upon .the inner side of the outer wall bent in close contact with'said outer wall, thence at vright angles to its length, as at b2, and thence upwardly upon a curved line, as indicated in said Fig'. 3, the diaphragm or partition t being perforated, as at b, all as clearly shown in Fig. 3.`
, In practice a plurality of sections are united to forni a shaft or pipe of the desired length, the sections being fitted one within? another, as indicated clearly in Fig. 3,l the `shoulders a a5 finding bearings against the upper end of the piece B, which is bent over the end of the inner and outer walls ot the section, as indicated in-Fig. 1.
The strip B forms a spacing-collar, leaving an interior projecting piece B2, which serves as central and entering guide in uniting the sections.
Vhat We claim as new is* 1. A hot-air pipe formed with inner land outer walls, the inner wall being bent at right angles, as at a., thence in line with the pipe,
as at a', thence at right angles to the bentpart. of the pipe, as at a2, and v,pertorated and' same length as fio then in line with' the pipe, as at a3, and the outer wail bent at right angles, as at a5, upon the same piane as the right-angled portion a2, and thencefparallei with and embracing the end and two sides of the portion a3, and the other end of the pipe provided with spacingcollar having perforations in line with the perf forations in the right-angled portion a2, substantiaily as and for the purpose specified.
2. A hot-air pipe formed of an inner and A outer wail, one of which is extended beyond the other, and a piece of metal, as B, arranged between the inner and outer wall, with ite endsrbent over and embracing the ends of said inner and outer walls, with one portion b' extending parallel and in contact with the ffouter wail and thence bent at right angles, as fiat b2, forming a recess for the reception of the .iib upon the adjacent. end of and entering 'section of pipe, the diaphragm thus formed being perforated,y substantially as shown and described.
f3. A hot-air pipe formed at one end with a perforated right-angled portion and having the inner and outer walls extended in line with the pipe and united and the other endf; provided with a perforated spacing-collar arranged between the inner and outer wailss-Qfzf.;
hold the rib on the end of the first-mentioned' section of pipe.
.In testimony whereof we'afix our signatures in presence of two witnesses.
