MOVABLE VENTILATOR FOR VAULTS.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed June 23, 1908. Serial No. 439,993.

To all whom it may concern.

Be it known that we, FREDERICK S. HoLMEs, a citizen of the United States, residing at New York, in the county of New York and State of New York, and GEORGE L. DAMON, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Movable Ventilators for Vaults, of which the following is a specification.

The object of our invention is to provide a convenient and effective means for establishing ventilating connection between the inside of a vault and an outside air passage, while I the vault is open, which means is readily removable or withdrawn within the vault previous to closing the door or doors.

With this end in view, our invention con sists in arrangement of parts as well as the construction thereof, hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical section through a portion of a vault and its vestibule with our improved ventilator applied thereto and in position assumed when the vault is open, the withdrawn position being shown in dotted lines; Fig. 2 is a horizontal section of the vestibule and a portion of the vault with the ventilator shown in plan and in position of use; Fig. 3 is a vertical sectional detail view, on an enlarged scale, showing the connection of the movable flue with the outer flue of the air conduit, and the method of connecting the outer foot-plate with the inner foot-plate; Fig. 4 is a vertical sectional detail view, on an enlarged scale, of the inner portion of the movable flue of the ventilator, in position. corresponding to that of Figs. 1, 2 and 3, and showing the connection with the inner transverse flue and the relation of the inner foot-plate to the finish-flooring of the vault; and Fig. 5 is a vertical transverse section on the line 55, Figs. 1, 2 and 4, the parts being shown on the same scale as Figs. 3 and 4.

1 represents a portion of a fire and burglar proof vault of known construction. 2 is the vestibule thereof, 3 the inner door frame, adapted to be closed by doors 4 (Fig. 2) and 5 the outer door frame adapted to be closed by the door 6. It has heretofore been oustomary to ventilate vaults of this character by the introduction of a removable air suction conduit, usually through the upper portion of the doorway in such position as would offer the least inconvenience to travel in and out, said ventilator being removed and laid to one side on the outside 0f.the vault when it became necessary to close the doors.

According to our invention, we employ a movable conduit section or flue 7 adapted to assume a position across the thresholds of the doorways when the safe is open, and to connect at its respective ends with an inner air flue 8 or other air space, from which it is desired to exhaust air and with an outer fixed flue 9 (preferably beneath the flooring of the outer room), which leads to any suitable point of discharge or of connection With an air exhaust means; said movable conduit section being adapted to support a foot-way to facilitate passage over it to reach the interior of the vault. The foot-way is preferably constructed with an outer removable inclined foot-plate 10 which may be placed to one side when the vault is closed, and an inner foot-plate 11 mounted upon the flue 7 and carried with said section into and out of place as the flue is withdrawn to permit closing or return to position of use when the vault is open. Flue 7 is preferably mounted through a hinging joint 12, in a frame 13 secured within the vault in such position as to bring the foot-plate 11 on a level with the finish-floor 14: within the vault. Said section is provided with an intake 15 of such construction that it makes a suitably tight connection with the air space 8 when the section is in position of use, and a discharge end 16 which fits into the vertical leg 9 of the flue or conduit 9 when the section is in the position of use.

Referring to Fig. 3, it will be seen that the outer discharge end 16 carries a packing 17 that flts a frame 18 at the upper end of the flue 9-9 which frame is also preferably provided with a screen 19 to protect the mouth of the flue. swinging flue 7 is provided with an oifset 20 beyond which its foot-plate projects as at 21, to provide an interlock for the outer footplate 10 which is preferably mounted on a frame 22 formed with a bearing foot 22 and an end 22 that projects beneath the overhanging end of the foot-plate. 7

By reference to Fig. 4, it will be seen that the inner end of the movable flue 7, is provided with a deflecting end 24 which fits within an opening formed in the frame 13 that supports the hinge 12 and provides a guard around the hinge.

The inner transverse flue 8 is preferably connected by downtakes 25 with collecting flues 26 that extend along the upper portion of the vault, for the purpose of drawing air from the warmer part of the area to be ventilated.

When the parts are in the position shown by full lines on the drawings, an air current set up in the conduit, either by suction at an external point or by pressure developed within, will cause the air of the vault to be withdrawn and replaced by fresh air from the outside. When it becomes necessary to close the vault, the outer foot-plate 10 is withdrawn, the movable flue 7 is raised upon its hinging end until it assumes the position shown in dotted lines in Fig. 1, where it will be self-sustaining by the construction of its hinge, and the doors may then be closed in the usual way. Upon opening the doors, the movable flue is readily lowered to position of use. In its movements, the movable flue carries the inner foot-plate 11 with it, moving it alternately from the position in alinement with the inner finishing floor of the vault to a position where it will be out of the way of the doors in closing the safe. Then the flue is raised, the outer foot-plate 10 may be placed over the outer flue 9-9 in order to provide a place to stand while manipulating the outer door.

We do not limit ourselves to any particular construction of the inner and outer flues. The outer flue may be made of sheet metal piping of desired section, while the inner flue running transversely of the vault just inside the vestibule, may be formed by the bottom masonry, the transverse floor beams and the flooring, or one of said beams and the inner facing of the vestibule frame. The movable flue, while preferably made in the form shown in Fig. 5, may obviously be of different form or proportions and its outer end The outer end of the i i may be given such shape as desired, to properly conform to the doorway through which it is to project. i

, Having thus described our invention, what j we claim and desire to secure by Letters Patent is:

1. In combination with a safe or vault, a ventilating conduit comprising an outer flue and a movable flue adapted to communicate j with the outer flue and movable into and out of a position extending across the bottom of l the vestibule. I

2. In combination with a safe or vault, a

ventilating conduit comprising an outer flue and a movable flue adapted to communicate with the outer flue and movable into and out of a position extending across the bottom of the vestibule said movable flue providing a foot-way across the vestibule.

3. In a ventilator for vaults, the combination. of an outer flue, a movable flue adapted to connect with the outer flue and lie across the bottom of the vestibule, and a foot-plate carried by the said movable flue.

4. In a ventilator for vaults, a movable flue hinged at one end within the vault, and movable upon said hinge into and out of a position lying across the bottom of the vestibule, and means cooperating with said movable flue to direct an air current there through.

5. In combination with a vault, an inner ventilating flue, and a movable flue adapted to communicate with said inner flue and to be moved into and out of position across the bottom of the vestibule.

6. In combination with a vault, having an inner floor and an inner flue below the floor, a movable flue carrying a foot-plate, and adapted to communicate with the inner flue, and movable into and out of position across the bottom of the vestibule.

7. In combination with a vault, an inner ventilating flue leading from a portion of the vault to a space within the vestibule, a movable flue mounted upon a hinge within the vestibule movable to bring it into communication with the inner flue and into communication across the bottom of the vestibule and an outer flue with which said movable flue also communicates when lying across the bottom of the vestibule.

8. In a ventilator for vaults, the combination of the inner and outer fixed flues and the movable flue having hinging connection at one of the fixed flues and movable into and piut of communication with the outer fixed 9. In a ventilator for vaults, the combination of the movable flue mounted upon a hinge within the vault movable to a position across the bottom of the vestibule, providing a foot-Way thereover, and projecting beyond the vestibule, an outer flue with which the movable flue communicates when in said projected position, and an outer foot-plate sipported by the projecting end of the mova e which the movable flue connects when in 15 horizontal position substantially as set forth.
