Description
STATES TNITED PATENT FFIC.
- INHALER.
SPECIFICATION forming part of Letters Patent No. 672,177, dated April 16, 1901.
Application filed February 8, 1900. Serial No. 4.553. (No model.)
.To all whom t may concern,.-
Be it known that I, WILLIAM H. METCALF, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Fresh-Air Inhalers and I do hereby declare the following,whentaken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-
Figure 1, a side View, partially in section, of` a respirator constructed in accordance with struction of a simpledevice which may be' easily applied and by which the air admitted may be readily medicated, if desired; and it consists in the construction, as hereinafter described, and particularly recited in the claims. n
As herein shown, the device is arranged in connection with the meeting-railr A' of theV upper sash 'of' a window, and consists of` a tube B, adapted to be inserted upward through an opening C,'formed in the rail A.
The said tube is provided at its lower endy with a mouth D and isvof a length'greater than the thicknessof the rail, so as to extend above the same. In thevupper end of the tube is a vertical slot a, opening into'which are transverse notches b,'more or lessin number. Over the tube By is set a'cup E,' forn1ed with a centrally-,- arranged collar/F, .corre-v sponding in internaldiameter to the external diameter of the tube B, and'.projectngfronn` the inner wall of the collaris astudQ-adapted to enter the groove a and be turned into one of the notches b, soas to` interlock the cup lwith the tube as well as to hold the tube' in position. In the outer wall of this cup is a bayonet-slot d, and over the cup is placed a cap G, ,having a projection e for engagement with the slot, whereby the cap is locked in position. The top of this cap extends upward, forming a cylindrical neck H. At the lower end of the neck H, I preferably provide a wire screen I, and at the lower end of the tube B is a similar screen J. Over the neck H is placed a pipe K, of rubb'er,which is of the required length and is connected at its opposite end with an end piece L, which is preferably of sufficient size to inclose the mouth and nose. In this mouthpiece is a trap M,
,which permits inspiration, but closes against exhalation. In place of the mouthpiece shown it is evident that other forms of mouthpieces may be used, or smaller devices may be employed to permit inhaling through the nostrils.
With a device of this character air from the outside may be admitted to a room and conducted to any desired point without cooling theair in the room, and, if desired, a medicament may be placed in the cup.
While I have shown the tube B as extending vertically through the meeting-rail of the upper sash, it is evident without illust-ration that it might extend transversely th rough the lower rail of the lower sash, through the casing, through the glass itself, or, if desired, through a door or other part of a building, it
beingunderstood that the distance between n the mouth D and the bottom of the cup C will -correspond substantially to the thickness of the part through which it extends, and the tube maybe made longer or shorter, according to circumstances, orfbe provided with a tions. Y y Y Iam." aware that,window-ventilators have been arranged in whichv a f tube is passed through a frame or screen adapted to be in lserted within a window-casing and i n connecvtion with tubes, whereby fresh air may be ad' 'n iitted to an apartment and conduetedto any `desired point therein; but such deviceshave been vof a complicated nature and not adapted for direct attachment to a window-frame or `greater'or less n umber of interlockingnotches, whereby it is easily adj u'stedin various posiother convenient part of a building. My device is so simple in construction that it is inexpensive and when applied to a window may be used without opening the Window.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isy l. In a fresh-air inhaler, the combination with a tube adapted to be mounted in a Window-frame and open at its outerend, of a cup attached to the inner end of said tube, a cap adapted to be secured over said cup and formed with atubularneck and a pipe coupled with said neck, substantially as described.
2. A fresh-air inhaler, comprising a tube, a cup adapted to set over the upper end of said tube, and vformed with an upwardly-extending eentral collar for engagement with the said tube, a cap for engagement With said WM. I-I. METCALF.
