VENTILATING APPARATUS.

Application filed November 13, 1918.

To all whom it may concern:

Be it known that I, LUTHER J. VALKER, a citizen of the United States, residing at Helena, in the county of Lewis and Clark and State of Montana, have invented newv and useful Improvements in Ventilating Apparatus, of which the following is a speci fication.

This invention relates to a ventilating apparatus, and more particularly to means for supplying fresh air in a sleeping compartment, and directly from an opening communicating with the exterior, to an individual who may be at a slight distance from the window and protected from draft there from, and especially for supplying air during sleep.

In stormy weather it is difficult to obtain the proper amount of ventilation in a sleeping compartment, and under any circumstances it is difficult to avoid drafts which may be inconvenient, and at times dangerous. By the use of the device herein described, a continuous supply of fresh air is provided, without the resulting disadvantages.

In the drawings, Figure 1 is a perspective view of the device in operative position, and Fig. 2 is a fragmentary view, chiefly in section.

In carrying out my invention I provide aduct 10 which may have connection with an opening provided directly in the glass of the window sash, or which may be connected with a board or othersimilar member 12 placed in the opening afiorded by throwing the sash. of the window to open position.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Serial No. 262,312.

Theduct 10 has connection with a plurality of minor or branchingducts 13 and 1& the latter terminating in portions suitable for engaging the nostrils. The duct is partly supported by means of a supportingelement 15, in order to retain the device in proper position during sleep. An elastic band is connected with the main portion of the de vice and passes around the head of the sleeper, so that the movement of the head will not result in the displacement of the branching tubes supplying air through the nose, nor in the displacement of themain duct 10.

The supportingelement 15 includes a tripod and a rotatably mounted member including a tubular portion and a shank portion, the latter passing through the head of the tripod.

While th device is simple in construction, it is extremely eflicient in operation, and there is no portion which will readily get out of order.

What is claimed is:

In a device of the class described, a main duct for connection with a window opening, a supporting element comprising a horizontal tubular member rotatably mounted and adapted to support one end of the duct, a plurality of branching tubes connected with the duct and proportioned to convey air to the nostrils, and an elastic band connected with the duct and adapted to pass around the head of the individual using the device.

In testimony whereof I aflix my signature.

LUTHER J. WALKER.
