CHIMNEY (JAB. APPLICATION FILED 00T.6, 1910.
*-Paten ted Nov. 29, 1910 .l'lllll v III EDWIN JAMES COCHRAN, 0F STERLING, ILLINOIS.
CHIMNEY-CAP.
T 0 all whom it may concern:
Be it known that I, EDWIN J. COCHRAN, a citizen of the United States of America, and a resident of Sterling, in the county of VVhiteside and State of Illinois, have invented certain new and useful Improvements in' Chimney-Caps, of which the following is specification.
This invention relates to that class of chimney caps in which the revoluble cowl or shield is mounted on a vertically arranged standard carried by the fixed supporting member of the cap, and has for its objects to provide a simple and substantial structural formation and arrangement of parts of the fixed supporting member adapting the same for ready adjustment to fit varying diameters of the discharge pipes or collars of chimneys or the like. Also to provide a simple and efiicient structural formation and combination of parts comprising the journal connection between the revoluble and fixed members of the chimney cap, whereby a free turning movement of the rev oluble member is attained during long continued use without liability to clogging and stonnage by accumulations of soot, and which at the same time afiords a strong and substantial connection of the parts, all as will hereinafter more fully appear.
In the accompanying drawings: Figure 1, is a fragmentary vertical sectional elevation on line a2w, Fig. 2 of a chimney cap embodying the present invention. Fig. 2, is a horizontal sectional elevation on line w00, Fig. 1. Fig. 3, is a detail top view of the revoluble spider which carries the cowl shield member.
Similar reference numerals indicate like parts in the several views.
Referring to the drawings, 1 represents the upper end of the outlet pipe orcollar at the end of a smoke chimney or the like, and 2 the revoluble plate metal cowl or shield, pivoted in superimposed relation above the outlet opening of said pipe or collar and adapted to prevent drafts of air blowing down the chimney and at the same time aid in producing an upward draft in the same.
3 is a central spider having a central vertically orificed hub 4 and a plurality of radial arms 5, which arms in turn are formed with a series of notches or recesses 6, preferably in the top face of the arms, as shown.
Specification of Letters Patent.
Application filed Gctober 6, 1910.
Patented Nov. $9, 1910.
Serial No. 585,690.
7 are bracket bars corresponding in numher to the radial arms 5 aforesaid and individual thereto. Said bracket bars are provided at their outer ends with angularly arranged ears 8 for permanent attachment to the upper end of the outlet pipe or collar 1, by means of attaching bolts 9 as shown, or by other equivalent fastening means. At their inner ends said bracket bars are provided with lateral lugs 10 adapted for engagement in the aforesaid recesses 6 of the spider arms to prevent independent movement between the parts after the same have been properly assembled.
11 are transverse bolts passing through orifices formed therefor in the spider arms 5 and bracket bars 7 and adapted to secure said parts together in assembled relation. W ith a view to permit the before described adjustment between the parts, the orifices 12 in one or the other of said arms or bars will preferably be of an elongated form, as illustrated in Fig. 1.
18 is a vertically arranged standard, preferably of the ribbed form shown, and having at its lower end a tapering shank 1% which fits the bore of the spider hub a, and is secured in place therein, by a nut and washer fitting a screw-threaded stem at the lower end of said shank. Midway its height said standard is provided with an annular collar 15 for the purpose hereinafter stated, and at its upper end with a circular bearing stem 16 for bearing engagement in the socket of the revoluble spider hereinafter described.
17 is the revoluble spider, above referred to, the main portion of which is arranged vertically'at the side of the aforesaid standard 13, and provided at its lower end with a laterally extending horizontal collar 18, adapted to encircle the lower portion of the standard 13, and have bearing upon' the same. At its upper end said main portion of the spider is provided with an enlarged head 19, which extends laterally and is formed with an open bottom recess for the reception of the circular bearing stem 16 of the standard 13 to provide a bearing therefor. The bearing itself may be of any or dinary form such as one or more interposed balls, or a cone formation of the upper end of the stem 16 and a corresponding formation of the recess in the aforesaid enlarged head 19.
20 is an angularly arranged extension formed on the upper end of the head 19 aforesaid, and provided with a transverse recess for the reception of the attachin. cross-bar of the revolving cowl or shiel now to be described.
21 is a ductile-metal bar fitting the transverse recess of the aforesaid extension 20 and secured therein by a fastening bolt 22.
Said bar is of the elongated form shown in Fig. 3, and is provided with a series of rivet holes 28, by which it is secured by rivets to the inner surface of the cowl or shield-2. With the described construction the ductile nature of the bar 21 permits of 5 its being readily bent to fit the interior sur face of the cowl to attain a substantial attachment of the parts in the assembling operation.
24 is a split pin or bolt passing transversely through the main portion of the spider 17 and adapted to project at -a point immediately beneath the annular collar 15, before described to prevent any upward displacement of the cowl or shield 2, from its supporting standard 13, while permitting a free rotation of the same.
Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is
.1. In a chimney cap, the combination of a revoluble cowl, a fixed support for the same comprising a spider formed with a central hub and a plurality of radial arms, a series of bracket bars secured to said arms in a radially adjustable manner, and means for interlocking said bars and arms at their adjustments, substantially as set forth.
2.7In a chimney cap, the combination of a revoluble cowl, a fixed support for the same comprising a spider formed with a central hub and a plurality of radial arms, a series of bracket bars secured to said arms in a radially adjustable manner, and means for interlocking said bars and arms at their adjustments, the same comprising a series of notches in one of said parts and lateral lugs on the other parts for engagement in said notches, substantially as set forth.
3. In a chimney cap, the combination of a K spider having radial arms adapted for engagement with a smoke pipe or collar and formed with a vertical orifice in its hub portion, a vertical standard carried by said hub and formed with a collar intermediate of its height and with a central hearing stem at top and a revoluble spider comprising a main vertical portion provided at its lower end with a lateral collar encompassing the aforesaid standard, at its intermediate height with means for engaging beneath the aforesaid collar, and at its upper end with an enlarged head having an open bottom recess for engagement with the bearing stem aforesaid, the said head having an angular extension formed with a transverse recess for the reception of the ductile bars aforesaid, substantially as set forth.
4:- In a chimney cap, the combination of a revoluble cowl, a transverse ductile bar having permanent attachment thereto, a fixed spider having radial arms adapted for engagement with a smoke pipe or collar and formed with a vertical orifice in its hub portion, a vertical standard carried by said having an angular extension formed with a transverse recess for the reception of the ductile bar aforesaid, substantially as set forth.
