Further objects of the inventiony are` to 20 provide a device of this character'which is simple and inexpensive in "its l"",constrnbtion, which can be-quickly placed-in" position and n worn without discomfort, which willconvey 'A an Aample supply of fresh! air" from" the "outjf 25, side of a building to a sleeper within`i"th`e""" "same, and `which can be adjusted for use by Vdifferent persons. H

`With these and other` objects in view, the

` invention consists in certain novel combinaa0 tions and arrangements of the parts as will g more fully appear as the description prof ceeds, the novel features thereof being pointed out in the ap ended claims. For a full un erstanding ofthe invention, t5 reference is to be had to the following description and Figure 1 is a perspective view of a sleepn ing hood constructed Vinaccordance with the te invention, lshowing ythemanner of using the same. n .f

vF ig. 2 is a' vertical longitudinal sectional view through the shell of the hood.

Fig. 3 is a fragmentary`` sectional view t5v through the fresh air inlet valve casing.

- Fig. l is a transverse sectional view through a windowsashfshovving the manner of applying the outer end of the .flexible air Vtube thereto.

l Corresponding and like parts arelreferred to'in the following description and indi` cated in all the views of thedrawings by the saine reference characters. s 1

A suitable head strap 9 may be provided n forv holding the shell l in position over the nose, and a channel shaped binding V10 is applied to the` inner edge ofthe shell land plate 2, said bindingstrip carrying a soft .-packinginember such as the rubber tube l()a which'engages the face andv enables the de-` vice to be worn without discomfort. The

'edges' ofthe' shell l will have to becnt and 90C `shaped to conform to the face of the pari ticular person whois to use the device,` and. after theedges have been properly Cut and shaped the binding strip 10 canbe applied thereto. The plate 2 is adapted to be used 95 interchangeably in connection with any one of a number of shells l, so that the device can be used by any person in a family or household by merely applying the plate 2 to a shell or nose guard 1 which has been prop- 100 erly adjusted and fitted for the particular person.
