Application filed January 16, 1923. Serial No. 612,976.
This invention relates to a ventilator and more particularly to a ventilator base. The invention has for its object to provide a ventilator base with which labo-r and expense of erecting and installing ventilators on roofs of buildings and like structures of different pitch may be simplified and reduced to a minimum.
To this end, the ventilator base is composed of a hollow upper member to which the ventilator is connected, and a lower member having an upright portion with which the hollow upper member communicates, and is preferably secured thereto in a substantially vertical position. The lower member' is designed to be applied to the roof, either flat or pitched, and the `upright portion of'said lower member is suitably constructed so as to enable the hol low upper member of the base to be made as a standard for all roofs and to be preferably secured t the said upright portion in a substantially vertical position irrespective of the character of the roof.
These and other features of the invention will be hereinafter described and pointed out in the claim at the end of this specification.
In the drawings illustrating the preferred form of the invention, Fig. 1 is an elevation with parts in section illustrating a ventilator erected upon the ridge of a roof by means of a base embodying the present invention;
Figs. 2 and 3 are elevations showing the ventilator base applied to a pitch and a flat roof respectively;
Fig. 4, an inverted plan of the ventilator base in the position shown in Fig. 3; and
Fig. 5, a cross section on the line 5-5 of Fig. 1.
Referring to the drawing, the ventilatorbase illustrated therein comprises in general a hollow upper member 10 having provision for connection to the ventilator 12, preferably by an upstanding pipe section 13 arranged to fit into the lower end of the vent-ilator. The hollow upper member 10 has cooperating with it a lower member 111 for connecting it and the ventilator with the opening in the roof.
For erecting ventilators upon the ridge of the roof, the ventilator base will preferably be constructed as illustrated in Fig. 1, wherein the lower member 14 is shown as formed in two parts or halves, each having an upright portion 15 extended into the lower end of the hollow upper member 10 and c0- operating therewith to form an extension thereof. yEach upright portion 15 is provided with a curved outer end wall 17, with opposed side walls 18 preferably of approximately sector shape and provided with relatively short inner edges 22, which Vare inferent pitch. The curvature of the end walls 17 is preferably such as to permit the angular movement of the upright portions 15 and retain the end walls 17 in engagement with the internal surfaces of the end walls of the hollow upper member 10, to permit the upright portions to be bolted or otherwose secured to the upper member 10. In practice the adjacent portions of the flange 19 upon each of the upright portions 15 are preferably connected together and are capable of being bent during the erection of the ventilator base, to secure the desired angular adiustment of the parts. n y
The side walls 18 of the two parts or halves of the lower member 14 may be made of one piece of sheet metal, and are cut away as shown to form V-shaped openings 20 to assist in the angular adjustment of the upright portions 15 and whose walls form the inclined edges ofsaid upright portions.
llVhen the ventilator is to be'erected upon a pitch roof at al place other than atthe ridge, one part or half of the lower member .14. used on the ridge will be employed to form the lower member of the base for the pitch roof, as illustrated in Fig. 2, it having opposing segmental shaped side walls 18, curved outer end walls 17- and upwardly and rearwardly inclined inner edges 22. The lower member 14 in such cases is' also provided with a flange 19 secured to the lower ends of the side and end walls as shown. The end walls 17, 22 are extended in the same general directionto permit the flange 19 to assume dilferentangular positions, according to the pitch of the roof, so as to enable the upper member 10 to be fitted to the lower member and yet be in a substantially vertical position.
Both of the V constructions illustrated in' Figs. l and Q may be used upon av flat roof such as is illustrated in Fig. 3. In such iii-y stance the iange of the lower member 14 assumesa horizontal position and the upper gmember l() a vertical` position, with the upright portionV of the lower member extended rup into the upper member. Vhenthe lower member 14 is composed of two parts or halves as shown in Fig. l, the V-shaped notch or opening Q() will be extended `to near the flange 19 to `facilitate angular adjust-v nientof the two parte to the roof on oppo- -Site sides of the ridge, and also to enable the said parts to be easily severed for use ndividually as shown in Fig. 2.
From the above description, it will be obl served that the improved ventilator base enables ventilators to be easily and economically erected upon roofs oi different pitch and also uponditferent parte of the roof. In
practice, `the hollow upper member may be i manufactured asia standard, and the lower member inadeof vdifferent sizes and shapes, and both may `bestored in warelio'uses, so'
Y that when a job arises, a standard upper member may be shipped to the job with a pluralityof different shaped lower members, one of which is selected on the 10b to be applied to `thevridge of the roof, the inclined side, oi' toa lat roof, as the case may be.`
The present invention, therefore, eliminates the necessity for accurate data as to the exact pitch of the roof, and at the same time leliminates vsheet `metal Work at the job for fitting the `ventilator to roofs of `diiferent pitch. In addition, all of the manufacturing operations in connection with the ventilator y and ventilator base may be performed in the shop or factoryaiid thus reduce the total cost of the erected ventilator.
While the preferredembodiment of the invention hasrbeen 'illustrated and described,
it will vbe, understood that the invention `may be embodied in other `forms within the scope ol the following claim.`
