VENTILATUR FOB WINDOWS.

SIDNEY HEPTINSTALL, OF MARION, VIRGINIA.

VENTILATOR FOR -WINDOWS.

SPECIFICATION forming part of Letters Patent No. 660,510. dated October 23. 1900 Application filed July 15, 1899.

To all whom it may concern.-

Be it known that I, SIDNEY HEPTINSTALL,

a citizen of the United States, residing at Marion, in the county of Smyth and State of Virginia, have invented a new and useful Veneral, and more particularly to that class which are adapted to be placed within a window and to have the window'sash closed down thereupon, the object of the invention being to provide a construction which may be easily fitted to a window of any size within certain prescribed limits and one which when thus fitted will be effective in its operation.

In the drawings forming a portion of this specification, and in which similar numerals of reference designate corresponding parts in the several views, Figure 1 is an elevation of the lower portion of the inner side of a window-frame, showing the employment of the ventilator in connection therewith, the sash being closed down upon the ventilator. Fig. 2 is a transverse vertical section of the ventilator, the positions of the sash and sill being indicated in dotted lines. Fig. 3 is a rear perspective of the ventilator detached.

Referring now to the drawings, the ventilator consists, essentially, of two

similar elements

5 and 6, each of which consists of an end piece 7, of quadrant shape, upon the curvilinear edge of which is fixed a similarlycurved plate 8, of metal, from one edge of which there is projected a vertical flange 9, the outer face of which lies in the same vertical plane with the flat vertical face 10 of the quadrant end piece.

The flange 9 of the element 5 has its edge turned over to form a close bead 11, which beaded edge is adapted to slide within the ihclosure of the tnrnedover edge 12, which forms, in effect, a slideway, as shown. The plate of the element 6 has the curvature of an arc whose radius is somewhat greater than the radius of the arc of the curvature of the element 5,whereby the two elements may have a telescopic action, the element 5 sliding into the inclosure of the element 6. A

Secured to the inner end of the element 5 is a third quadrant-shaped block or plate 13,

Serial No. 723.952. (No model.)

having a recess in the lower portion of its front edge to which is fixed the end of a beam 14, which end is halved for a purpose which will be presently explained, the opposite end of the beam being fixed to the quadrant at the opposite end of the section 5. A second beam 15 is fixed at the lower front edge of the quadrant at the outer end of the section 6 and lies in the plane of the beam 14. The inner end of the beam 15 is halved and has its narrowed extremity passed into the recess in the segment 13, this narrowed extremity receiving the similar inner extremity of the beam 14, and thus permitting the inward telescoping of the

sections

5 and 6, either or both of the diminished ends of the beams sliding transversely of the quadrant 13 until the proper adjustment is secured, after which they are fixed to the quadrant 13 by means of nails, screws, orin any other desired manner.

Within each of the

sections

5 and 6 is pivoted a slat 17, which slats are provided with trunnions 18, which enter perforations adjacent the upper ends of the front edges of the quadrants. Thus may the slats or shutters be swung inwardly of the

sections

5 and 6 or may be moved outwardly to lie closely upon the sills 14 and 15, respectively, to close the ventilator. In order to hold the slats at different points of their pivotal movement, spring-pressed bolts 19 are fixed to the slats and are adapted to enter locking-perforations 25 in the quadrant 13. The slats are made, preferably, of wood, and thus may be readily cut down to the proper length, after which the sections may be drawn outwardly and then moved inwardly to engage the trunnions with their respective perforations.

As shown in Figs. 1 and 2 of the drawings, in the application of the ventilator the sections are adjusted to the proper positions mutually, after which the ventilator is disposed between the sides of the window-frame and with the beams 14 and 15 in the recessed portion of the sill, which normally receives the window-sash when the latter is shut down. The window-sash is then moved downwardly to lie upon the upper surfaces of the

sections

5 and 6 and in engagement with the rear faces of the flanges 9. In order to hold the ventilator more securely in this position,

hooks are pivoted to the outermost quadrants and are adapted to engage eyes 21 upon the inner faces of the window-frame.

To prevent the ingress of insects, 850. each

section

5 and 6 has stretched over its lower open side a screen 22, which latter are adjustable with their respective sections.

Thus it will be seen that with the ventilator described an eifective ventilation of a room may be secured and that the ventilation thereof may be regulated as desired. Furthermore, it will be noted that the ventilator may be easily fitted to a window of any width within certain limits and also that by means of the hooks 20 and eyes 21 the ventilator may be held in position when the windowsash is raised therefrom.

It will be readily understood that in practice the specific shape of the ventilator may be changed and that the various parts thereof may be altered both in form and material without departing from the spirit of the invention.

Having thus described the invention, what is claimed is 1. A ventilator comprising two telescopic sections, forming an open-bottomed hood, each of the sections including a segmental end piece having a metallic plate fixed to the curved edge thereof, said plate being arcshaped in cross-section, the plates being bent upwardly in the planes of the front edges of their respective end pieces and having the edges of their upwardly-bent portions bent upon themselves, one of said bent edges forming a guideway, which slidably receives the other bent edge, a second segmental end piece fixed to the innermost plate, closures hinged to the end pieces adjacent the upwardly-extending portions of the plates and adapted to swing into the inclosures of the plates and end pieces, whereby said ventilator may be placed upon a window-sill and receive the lower edge of a sash against the plates with the upwardly-extending portions thereof lying against the inner face of the sash to hold the ventilator in position.

2. A ventilator comprising two telescopic sections including segmental end pieces hav ing arcshaped plates attached thereto, and forming an open-bottomed hood, one section having an additional end piece dividing the space inclosed into the two compartments and the plates being bent upwardly at their front edges and having the upper edges of said upwardly-bent portions bent upon themselves to form intermeshing slides, said upwardly-extending portions being adapted to lie against the inner face of a window-sash to prevent outward displacement of the ventilator, a closure for each of the compartments hinged to the corresponding end pieces adjacent the upwardly-extending portion of its respective plate and adapted to swing into the inclosures of the telescopic sections, and means for holding these closures at various points of their swinging movements.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

SIDNEY HEPTINSTALL.
