CHARLES C. GRIDLEY, 0F COLUMBUS, OHIO.

ROOF VENTILATOR.

Application filed October 4, 1.924.

1 0 aZZ whom it may concern Be it known that I, CHARLES C. Gummy, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Roof Ventilator, of which the following is a specification.

This invention relates to a ventilator to be employed in roofs for ventilating rooms thereunder.

The primary object of the invention is to provide a device of this character which will be exceptionally simple in construction, efiicient in operation and one wherein rain or other foreign matter may be excluded from the room ventilated by the device.

Another object of the invention is to provide a device of this character wherein the ventilation may be regulated at the will of the operator adapting the device for use under varying weather conditions.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a longitudinal sectional view through a ventilator constructed in accordance with the invention.

Figure 2 is a bottom plan view thereof.

Referring to the drawing in detail, the reference character 5 indicates the ventilating pipe which establishes communication between a room or compartment and the atmosphere.

Supported within the pipe 5 is a transversely disposed bar 6 provided with a central bearing 7 in which the vertically movable rod 8 operates, the rod 8 also operating through bearing 9 formed in the bar 10 which is supported adjacent to the upper end of the pipe 5. As shown, this rod 8 is formed with a head 11 at its upper end which is disposed in a plane above the upper end of the pipe 5 where it supports the cap 12 which is circular in formation and of a size to have its periphery dispos d be yond the pipe 5 in a manner as shown by F r 1 i the (lifet me T it ill e Serial No. 741,746.

seen that the cap 12 may be moved to a position to engage the upper end of the pipe 5 and to close the upper end thereof.

Mounted'adjacent to the upper end of the pipe 5 is a shield 13 which is substantially an inverted frustum and is supported by means of the braces or arms 17 that are shown as riveted to the member 13 at 18.

Positioned within the shield 13 and secured thereto by means of the rivets 15 are baffles 14- which are also connected to the pipe 5, by means of the rivets 16. These bafiies are designed to create a draught upwardly between pipe'5 and member 13.

Braces 17 have offset portions 18 which are secured to the pipe 5, the arms being secured to the shield 13 at 18. Each of these arms 17 is formed with a central offset portion 19 which is spaced from the upper end of the shield 13 where it has connection with the circular shield 20 which is supported in spaced relation with the upper end of the shield 13 by its connection with the arms.

The upper ends of the arms 17 extend inwardly and upwardly at 21 where they support the hood 22 which has its upper end open, the hood 22 being of a diameter to permit it to be fitted within the member 20 in a manner to provide a space therebetween to allow airto pass through the ventilator.

In order that the cap 12 may be adjusted Vertically an operating member 23 is provided, which operating member is formed with a curved end 2 1 to which is connected a flexible member 25 that also connects with the rod 8 at 26. The operating rod 23 is pivotally supported on the bar 6 at 27 and is provided with an opening in its free end to accommodate the chain 28, the opposite end of the chain resting in such position that it may be easily operated to move the cap 12 towards or away from the pipe 5 to control the passage of air through the ventilator The chain 28 may be supplied with a fusible link which would be destroyed in the event that the building in which the ventilator is positioned, should catch on fire to the end that the weight of he cap 12 will cause it to move to its closed position to shut off the draft through the ventilator.

From the foregoing it will bfi Obvious that due to this construction, a room or compartt q pe wi nteater constructed in acc rdan e w th 1 1. 9 iflvsntion, y be easily ventilated and the ventilator operated to exclude rainior other" foreign matter.

I claim A ventilator comprising the combination of a pipe section, shields arranged at the upper end of the pipe section and disposed in spaced relation with each other;transadapted to normally close the upper end of the pipesection, a pi-voted lever having a curved head arranged adjacent to the rod, a'fiexible member connecting one end of the curved: head to=the rod and means operatively connected to the lever for adjusting the rod vertically.

In testimony that I claim the foregoing asn'ny'owng Ph a vehereto afiixed my signa- 20 ture.
