SPECIFICATION forming part of Letters Patent No. 727,86), dated-May 12, 1903. I Application iledAugust 16, 1902. Serial No. 119,926. tNo model.) y

To LZZ whom, 1lil may concern: v Be it known that I, GEORGE B. SWOPE, a

citizen of the United States, residing at Wash- I ground and the first floorof the house where there is no cellar and at the same time is` adapted for use as a cellar-window lwhere the house is constructed over a cellar. p

Where there is no cellar, it is. sometimes customary 'to leave the space between the ground and the door open; but this is objec-l tionable for manyF reasons', and there are equally good objections to the practice of entirely walling this space up; and myobject is to produce a ventilator to be built in the wall of the house below the first door, whereby fresh dry air can be admitted to that part of the building when the Weather is seasonable and that can be closed entirely when the Weather is cold or damp.

In the accompanying drawings, li`igure 1 is a perspective view of my devic e,`the ventilator being open. Fig. 2 is a similar view, the ventilator being closed. Fig. 3 is a section about on the line 3 3 of Fig. 2. Fig. 4 is a perspective View looking from the inner side. Fig. 5 is adetail of the frame secured in the wall of the building. Fig. Gis adetail ofthe frame carrying the bars. Fig. 7 is a detail sectional view.

In carrying out my invention I use a rectangnlarV` metal frame A, the inside of the frame being of the size which it is desired to have ventilator or window. The top and bottom members of this frame project some distance beyond the side pieces, as shown at A, while the side pieces have' perforated lugs A2 formed intermediate their ends. This.

lrame is' placed in position during the construction ot' the building, the projecting ends A being` embedded in the brick or stone work. Adapted to fit in this iirst frame is the frame B, having transverse bars B', perforated lugs B2, formed on its side meinbers and adapted to register with the lugs A2, and at the upper and lower corners of one of the frames are the lugs BS, between whichis swingingly secured the 'hinged end of the lventilator C. From the upper member of the frame B and adjacent the pivoted end of the ventilator is a small metal block D, having a rectangular opening D' formed therein. A staple or eye E is secured to the upper por- .tion of the outer side of the ventilator in a position to register with the opening D when the ventilator is closed. A rod F is bent at one end and has an eye F' at said end, which .eye is adapted to engage the staple Ef The rod projects through the opening D/ and carries at its free end a ball F2, which ball is of sufficient size and weight to hold the ventilator in any position in which it may be placed and to.prevent the rod from being entirely withdrawn on the inner side of the frame.

'Ihe operation of my device will be readily understood. The first frame havin'g been embedded in the wall, the second is bolted to it by suitablebolts passing through the re` spective lugs, the ventilator being pivoted to the frame l) on the inner side and the rod and ball being secured to the staple yin the ventilator. When the ventilator is closed, as in Fig. 2, it is obvious that the weight at the end of the rod will hold it in such closed potion. Then open, as in Fig. 4, it is obvious that the weighted rod bearing against the edge ot the opening D' will act asa brace and hold the-'ventilator open, as movement of lthe ven= tilator could be had only by force suicient .to overcome the friction of the rod against -the block D.

If desired, a wire screen can be also inserted over the bars and on either the inner or outer side for the purpose of preventing mice and rats from passing through the ventilator.

Having thus fullyvdeseribed my invention, what I claim as new, and dosireio secure by Letters Patent, is

lu a ventilator, a rectangularframe having the side members projecting beyond the end through the aperture of the blockandsecured members perforated lugs on the end members, at one end to the shutter, and a weight on the a smaller frame, lugs on said frame adapted other end of the rod.

to register with the lugs on the larger frame, GEORGE B. SWOPE. a block on the smaller frame having an ap- Witnesses: erture formed therein, bars across the frame, W. H. DIAL,

a shutter pivot'ed to the frame, a rod passing CHAS. SPRINGER.
