y Appucationretruary10,1950, seriamamas's I l v 1 Claim. 1 The present invention relates to Ventilating caps for chimneys and the like and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
Generally the invention comprises a Ventilating cap for chimneys and the like and consists of a top cap which is circular in shape and which lies in a horizontal plane. Ribs, preferably three in number, are affixed to the top cap and depend therefrom. The ribs are bent in such manner as to each present a pair of integrally formed outwardly extending brackets, the sides of each of which form a thirty degree angle with a perv pendicular line. To the lower end of each of the ribs there is axed a vertically extending cylindrical base member formed of a single piece of sheet material fastened with a rivet or the like only adjacent its upper ends. The lower ends are bent outwardly on an angle to form a pair of channels for the reception of a like channeled member which,when forced into position in the first-mentioned channels, will act to draw the lower edges of the base member together to thereby lock Vthe same in position upon a chimney or the like. I
It is accordingly an object of the invention to provide a device of the character set forth --which is simple in construction, inexpensive to manufacture and yet effective and veiiicient in use.
A further object of the invention is the 'provision of a device of the character set forth having means for causing an updraft in a chimney upon which the same may be mounted regardless of the direction of the wind.
Another object of the invention is the provision of a device of the character set forth which may be readily placed in operative position without the use of tools of any kind.
A further object of the invention is the provision, in a device of the character set forth, of novel means for locking the same in position upon a chimney or the like.
A still further object of the invention is the provision, in a device of the character set forth, of novel means for preventing the formation of soot therein.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which: I
Figure l is a. side elevational view of an embodiment of the invention,
Figure 2 is a vertical sectional view of the device shown in Figure 1,
Figure 3 is a sectional view taken along line 3-3 of Figure 1,
Figure l is fragmentaryvertical sectional view of a base` memberfor ing a part of the invention, i *y I Figure 5 is a fragmentary sectional view taken along line 5-5 of Figure' 2,' f
Figure 6 is an `enlarged sectional view taken Y along line 6-6 of Figure 1,
Figure 'I isa fragmentary perspective view illustrating a male latchm'ember forming a part of the invention, and
Figure 8 is la perspective 'of afemale latch member likewise forming a part of l'the' invention. Referring more :particularly to the drawing, there is shown therein a'circular top plate I0 which extends in a vhorizontal direction.A and to which is fastenedA in spacedrelationV by vmeans of rivets IIr or the like' three vdependent ribs I2. Each` of the ribs extends vertically downwardly,
` as indicated at I3 in Figure 5, to join an upper upper lbracket pendent portion* I8 .Y
bracket havingfan, angular side portion I4 and a substantiallyl horizontal'lower portion I5. The y is Vintegrally connected to a like bracket having an angular portion I6 and a substantially Yhorizontal portion I1 to the. latter of whichfis integrally connected a vertically yde- It will be seen that the angular portions I6 and Ill-form substantially thirty degree angles with thel vertical `members I3 and v' 1v' A cylindrical base'member I9 is provided and is formed of a single piece of sheet material. The base member I9 extends vertically and is aflixed, by means of rivets 20 or the like, to the dependent feet I8. The ends of the base member I9 overlap, as indicated in Figures 4 and '1, and are attached to each other at their upper ends by means of a rivet 2|.
The lower ends of the base member are bent angularly and outwardly, as indicated at 22, to form male latch members which are adapted to be received in a latch plate 23 whose sides are bent inwardly, as indicated at 24, to form female latch members and whose top has an integrally formed finger piece 25 for manipulating the same.
Mounted upon the portions I4 of the upper bracket members is a frustro-conically shaped upper draft ring 26 which is aflixed to the brackets by means of rivets 21 or the like. A lower draft ring 28 is also frustro-conical in shape and is aflixed to the portions I6 of the lower bracket members by means of rivets '29 or the like.
It will be seen that the outer peripheries of the top plate II), the upper draft ring 26 and the lower draft ring 28 all lie in the same vertical plane and it will be seen that the inner 3 peripheries of the draft rings 26 and 28 are each of a lesser diameter than the diameter of the base member I9. Likewise, it will be seen that due to the vertical portions I3 of the ribs I2,
that the plate I0 is spaced from the upper end' of the draft ring 26.
While it is necessary to have a rivet 2I at the point indcatedin order to allow i011 expansion and contraction-at the lower end of the base member I9, it will be apparent that instead of the rivets II, 20, 2l and 29, that the parts fas-5; tened together by such rivets may be spot welded or fastened together in any 'other suitable,
manner.
In operation, it will be apparent that vthe base' member I9 may be placed around the upper end of a chimney or the like and that thereafter the latch plate 23 may be engaged over the latch y bind the same in position j'the vchimney and against 'ac cidentaldisplac nient therefrom.'
Due to the fact th a f, t r1e top plate lvnrisys'paed from the upper end of theupperldraf-tfrizg Y29 it will Vbe j seen;that it will be e tremel-y diflicult for soot to formjonthe under A v oftheplate lIII due to the fact'that there v `v1llbe `aJ passage of. "combustion gases or wind through .the space thus provided.. u
vIt will also beseen that due-:tc the Venturi effectV of thelupper and lower draft rings in comfbination withitne basemexnterfandrtp plate that, regardless; of the` direction of wind, against the assembly, that @vacuum will blde'nitely created at all timesw nitbase member I9 to 'thereby prevent any Ydraft from occurring in the chin1 ne;,1u'pozr-L which. the device .may be p1acedf. Y
It will also VAbe seen that ra d show -are prevented from enteringthe chimney .upon yivvlfii'clli thisv devcje -znay -b e-vvplaed. due tofthe fact that the a-ir carrying the same will `at all times cause an updraft in the base member I9 regardless of the direction from, which the snow or rain may 4 be coming. Again, heat from the gases of combustion impinging upon the upper and lower draft rings and the plate I0 will prevent any accumulation of snow or ice thereon.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many V minor forms of the inventionmay be made without departing `from the 'spirit thereof or the rscope of the appended claim.
What is claimed is: y ,A device of the character described compris- `ing'acirculartop plate, a plurality of spaced ribs dependent from said top plate and each bent to provide a pair of angular outwardly extending brackets, a frustro-conically shaped upper draft ring afXed to one of the brackets of each rib, a like lower draft ring afXed to the other of said brackets of each rib, a vertically extending hollowA cylindrical base memberrhaving overlapping ends, a rivet interconnecting rsaid 'overlapping endsadjacent the upper edge of said base member, said base bein-g aiixed to the lower portions `of the ends of the ribs, downwardly 'and out'- Wardly extending channels formed in the Vlower ends of the base member, a channeled frictionallyheldplate adapted to engage said-channels in the base member whereby to contract and latch the base member to a chimney or the like,
andahandle for said latch plate.
