DAMPER FOB VENTILATING SYSTEMS.

Specification of Letters Patent.

Patented Sept. 20, 1921.

Original application filed July 31, 1919, Serial No. 314,405. Divided and this application led February 14, 1920. serial No. 358,802.

T0 all whom t may concern.'

Be it known that I, WILLIAM G. FoRoIER, a citizen of the United States, residing at l/Vollaston, inthe county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Dampers for Ventilating Systems, of which the following is a specification.

This invention is a damper for ventilating systems, the present application being a division of an application filed by me July 31, 1919, Serial No. 314,405.

In the accompanying drawings,

Figure 1 is a vertical section of a portion of a building showing the application of my present invention;

Fig. 2 is a front elevation of the damper.

As shown in Fig. 1 of the drawings, the building in which my invention is embodied is of the hollow-wall type, a cardboard sheathing 7 extending the entire height of the building and spacers 8 being secured over said sheathing at intervals and serving to hold the same against the several sills and girders of the building. An outer sheathing 9 is secured to the outer sides of the spacers 8 and this sheathing may have a facing of any desired material or style according to the finish to be given the building. The roof 11 extends over the upper end of the space 12 between the inner and outer sheathings but the lower end of said space is open although it is covered with a screen 13 to prevent the entrance of insects. Spaced inwardly from the sheathing 7 is a partition 14, preferably of plaster, a deadair space 15 being thus provided between the sheathing 7 and the partition or wall 14. Spaced from the partition 14 is an inner wall 16 which forms the outer sides of the outer rooms. Obviously, a second dead-air space 18 is formed between the walls 14 and 16.

To permit circulation of air through the air space 12, I provide in the outer wall or sheathing 9 near the roof an opening 19 which is covered by a screen 2O to prevent the entrance of insects and around the said opening is provided a hood 21 vto protect the parts against weather elements. The opening 19 may be covered at will by a damper 22 slidably mounted in cleats 0r other guides 23 secured upon the inner face of the sheathing 9, said damper being provided with an opening 24 corresponding in form and size with the opening 19. At the ends of the damper 22 are brackets 25 to which are secured the ends of short cables 26 which cables extend over and are secured to segments 27 mounted for rocking movement at the opposite sides or ends of the damper. The segments may be pivoted upon the sheathing, but I have illustrated a support consisting of a bearing sleeve 28 secured through the sheathing 7 and the walls 14 and 16 in which the shaft 29 of a segment is journaled, this construction providing a more extended support for the segment and thereby more firmly holding it in its operative position. Upon each segment is an arm 30 to the free end of which is pivoted a link 31, the lower end of which is pivoted to an operating lever 32 fulcrumed in the wall 14 and extending through the sheathing 7 and the walls 14 and 16. The inner end of the lever 32 is hollow or provided with a socket 33 in which may be engaged a handle 34 to rock the lever when it is desired to adjust the damper and the slots or openings 35 in which the said lever plays may be lined with felt or similar material so that leakage of air through the same will not occur. If Ithe damper 22 be set in the position shown in Fig. 2 the opening 19 will be covered and there will be no circulation through the space 12 except such as may be due to the escape of air from the building. If, however, it be desired to permit a circulation ofair through said' space, a handle 34 is inserted in the socket of the proper lever 32 and said lever is raised so as to pull through the link 31 upon the connected segment and thereby shift the damper 22 so as to bring the opening 24 thereof into alinement with the opening 19 whereupon air will be permitted to enter the space 12 and flow down the same and carry off any moisture which may tend to collect therein.

Within each room of the building, I provide upper and lower ventilators, each consisting of a casing 36 inserted through the sheathing 7 and the walls 14 and 16, the upper casing being extended through the sheathing 9 while the lower casing opens through and terminates at the sheathing. Within each casing are blades 38 which may be operated by an adjusting shaft 47 extending into the room and equipped with a suitable handle or controlling means. By

properly adjusting these dempers, the ciropenin segments disposed :'Ldjacen-ty the culaton through the room may be efl'eotu-V ends 'o said damper and connected thereall controlled.
