- VENTILATOR. 4
V No. 893,585
To cut whom it may concern:
Be it known that I, OLIVER F. HILLPOT, a citizen of the United States, residing at E- a s-' ton, ,in the county of Northampton and State, of Pennsylvania, have invented anew 'anduseful'ventilator, of which the following aspecification. T a V This invention relates to ventilators -of that general class used. beneath the lower 'ofsashof a window for the purpose'of admitting fresh air into a room. I
' The principal object of the invention is to provide a ventilator of this type in which three deflecting plates are employed, all ar- 5 ranged-to direct the entering current of air in an u ward path, one of said plates being adjusta le to vary the path of deflection and serving also as a valve to out off the flow.
I A further object of the invention is to provide a device of this type in which the two permanent deflecting plates are disposed at an obtuse angle to each other for the purpose of permitting the entrance of av very large volume of air, and in which the outer or uppermost late is of sufiicient height to prevent the blowing over of a strong current of air and the creation of a draft in the lower por tion. of the room.
A. still further object of the invention is to provide a device of this type in which the movable or valve plate is pivoted at its lower edge and is movable to varying angular positions onboth sides of the vertical plane of its axis and which will act in all ositions of adjustment, except when fully c osed,to direct the current of air in an n ward path.
A still further object 0 the invention is to provide a novel form of friction device for engaging the pivot of the valve plate and maintaining the valve in any position to which it may be adjusted.
With these and other objects in view, the invention comprises the various novel features of construction and combination and 45 arrangement of parts, which will be herein after. more fully described, and pointed out particularly in the accompanying claims.
In the drawings Figure 1 is a plan view of a ventilator constructed in accordance ESQ-with the invention. Fig. 2 is a front elevation of the same. Fig. 3- is a transverse sectional view of the ventilator showing the same position 'in' a window, the valve plate-being artly open.

holding device for the valve pivot.
The main frame 1 of the-ventilator is preferably rectangular in form and is arranged to fit between the window sill 2 and sash 3. At the ends of the main frame are fitted extension pieces 'to' ads. t the ventilator to windows of different wldths. i In the centralipor tion of the frame is a horizontally elongated opening 5 that is preferably covere'd by a wire screen 6.
To the inner face of the frame are secured deflecting plates, the ldwer plate 7 being dis posed at a slight angle to the horizontal and the other plate 8 being arranged at a slight angle to' the vertical and obtuse angle to the plate 7 This forms a pocket the ends of which are closed by vertical walls 8. Pivoted within the pocket is a third deflecting plate 9, which also forms a controlling va ve, this plate 9 being movable to varying angular positions on both sides of the vertical plane of its pivot. The plate 9 is carried by' a rod 10 that extends through openings formed in the end walls 8. The projecting ends of the rod 10 are each encircled by a coiled s ring, the free ends or arms of which are held y pins 12 that are carried by the end walls 8, the pins holding the springs in such manner as to ex;- ercise considerable friction on the ends of the pivot rod, so that the valve plate may be ield in any position to which it is adjusted.
The valve plate 9 is pivoted at its lower edge at a point adjacent the juncture of the two )lates 7 and 8, and isadjustable to any angu ar position between the full open and full closed positions shown in Figs. 4 and 5, andin any, except the full closed position, the entering current-of air will be directed in an upward path by the valve plate. The quantity of air admitted is governed by the extent to which the valve is opened, thus, as shown in Fig. 3, a comparatively smallquantity of air can pass between the sash and the adjacent free edge of the valve plate, ut the entire volume of air which passes mu 1: move upward. When the valve is moved to the full open position, as shown in Fig. 4, a large volume of air may pass, but in this case also the air must take an upward path.
The u per edge of the plate 8 is located at such a distance above the level ofthe open ing 5 that the path of" the entering current of air must be deflected before it can reach the top ofthe plate 8, so that there is no possi- 3 binty of the air flowing over the top of the plate in such manner as "to'7create a draft in the lower portion of the room.
, It is found in practice that where a single inclined late is used in the path of a current of air, 1; e air will simply rise up over the plate-and will then fall to a greater or less extent, de ending on the velocity of the current an the temperature of the room. It is essential, therefore, that at least two deflecting plates be employed, so that the second plate may catch and correct the movement and direct the current into the desired path.
A single plate, moreover, would prove of little or no value if dis osed at but a slight angle to the horizonta and as the angle is raised to-more nearly approach a vertical plane, the size of the air passage becomes current of air W1 more and more restricted and if this is cor-- rected by an increase in the vertical height of the main openinlg of the ventilator frame, the
