WILLIAM SOHARNWEBER, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO GEORGE BAKEWELL, OF QUINCY, ILLINOIS.

WINDQW-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 532,487, dated January 15, 1895. Application filed September 10, 1894. Serial No. 522,640- (No model.)

To all whom it may concern.-

Be it known that I,W1LLIAM SOHARNWEBER, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Window-Ventilators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, wherein- Figure 1 is a sectional view through a window, showing the application of my improved ventilator thereto. Fig. 2 is a detailed view of the main frame of my ventilator. Fig. 3 is a detail view of the draft-regulating slide. Fig. 4 is a detail View of the draft-plate. Fig. 5 is a detail View of a frame which secures the weather-strips and wire-mesh to the main frame. Fig. 6 is a detail view of the manner of securing the weather-strip to the ventilator. Fig. 7 is a detail view of the deflector plate bracket and apiece of the deflectorplate; and Fig. 8 is a detail of one of the springs.

This invention relates to a new and useful improvement in window-ventilators, of that class in which the draft-openings are formed in a suitable frame, which frame extends the width of the window and is held in place by the lower sashimpinging thereupon.

Suitable means are provided on the frame to regulate the draft-openings, and in front of said openings is arranged a deflector-plate, which directs the incoming air upwardly, so that, should the ventilator be used when the weather is cold, the incoming cold air will create a circulation in the room.

In the drawings, A indicates the main frame, which is formed with a longitudinal opening or'slot, which slot is surrounded by a project ing flange a on the inner face of the frame. Introduced in the slot, is the draft-regulator B, which bears against the flanges a, and which frame B is of a length sufficient to permitmovement in the slot in the main-frame, so that its draft-opening b can be caused to register with similar openings 0 in a frame 0, or said frame B may be moved longitudinally of the slot so as to entirely closethe openings in the frame 0. A suitable handle B is preferably placed upon the frame B, by which the same. may be moved longitudinally. The frame 0, before referred to, is longer than the frame B, and has no longitudinal movement in the slot of the frame A.

Springs D are mounted on the frame A in some suitable manner, and bear upon the frame C so as to hold it against the frame B, and press frame B against the flanges a surrounding the slot of the main frame. The object of {these springs is to yieldingly hold the frame 0 against the frame B, so that if expansion should take place, due to dampness or other causes, neither of the frames would bind, and frame B could still be operated easily. Another function of springs D, by pressing against frame 0, is to compensate for any irregularity between the two frames, which might be due to the warping of either of them.

The back of the frame A is faced with a wire-gauze E, which prevents foreign particles, such as soot, &c., from passing through the openings 1) and c, and which forms a chamber behind the frame 0 from which the air is drawn through the opening.

The main frame A is formed with a groove in its side edges, into which is received one side of a piece of weather-stripping F, which weather-stripping is turned back upon the two brackets I, which are formed with a latorally-projecting fiange'i, which flanges at the upper, outer corner form an eye, into which is received the rolled edge j of the deflectorplate J, said deflector-plate being held in posi- 1. In a window-ventilator, the combination I with a main frame, slotted longitudinally, of a yielding ventilator-plate located within the slot of the main frame, and a longitudinally movable ventilator plate, also located within the slot of the main frame, which longitudinally movable ventilator-plate regulates the passage of air through the yielding ventilator plate, substantially as described.

2. In a window-ventilator, the combination with a main frame, slotted longitudinally, of a flange along the inner edges of the slot, a movable ventilator-plate which rests against said flanges, 'a stationary ventilator plate, which is behind the movable ventilator plate and holds the same in position, and springs on the main frame for yieldingly retaining the stationary ventilator-plate in position, substantially as described.

- with a main frame having a longitudinal slot formed therein, ventilator-plates which are yieldingly held in position in said slot, and a deflector-plate which is mounted upon the main frame in front of the slot, substantially as described.

In testimony whereof I hereunto affix my signature, in presence of two witnesses, this 31st day of August,'1894.

WILLIAM SCI'IARN WE BER.
