vSpecification of Letters Patent. Patented Dec. 2, 1919.

Application filed April 4, 1918. Serial No. 226,696.

To all whom it may concern Be it known that I, HUGH PURDY, a sub ject of the King of Great Britain and Ireland, residing at Belfast, Ireland, have 1nvented certain new and useful Improvements Relating to IVindows, of which the following is a specification.

This invention relates to windows of the class having a sliding sash adapted to open inward and its object is to provide an improved window of this class which will be perfectly weather proof when closed whlle it will also be capable of being opened inwardwhen required.

Under my invention, in order to give a finished appearance to the window, a sliding head is provided in connection therewith to fill in the top of the sash when in the closed position, the head having beveled end surfaces and being so arranged that, when the sash is raised, it is easily moved upward therewith so as to allow of the sash opening inward and when the sash is closed and lowered on to the rabbet of the frame bottom, the sliding head drops down again and closes up the opening which would otherwise be left above the sash top.

The sliding stile may be raised by direct lift, or by lever action, or otherwise, and by any suitable device or devices.

The invention can be applied to single or double sashes.

In order that the invention may be clearly understood I have hereunto appended explanatory drawingsshowing the invention applied to 'a single inwardly opening sash.

Figures 1 to 4 show a wooden sash.

Figs. 1 and l show the four corners of the window in front elevation.

Fig. 2 is a cross sectional view on the line 22, Fig. 1*.

Fig. 2 is a view showing the window raised for ventilation purposes.

Fig. 3 is a sectional plan view on the line 3-3, Figs. 1 and 1 Fig. 4 is a small view showing the whole window in front elevation.

Figs. 5 to 8 show a metal sash.

Figs. 5 and 5 show the four corners of the window in front elevation.

Fig. 6 is a cross sectional view on 6-6, Fig. 5

Fig. 7 is a sectional plan view on the line 77, Figs. 5 and 5*.

Fig. 8 is a small view showing a whole window in front elevation.

the line tially the same in 'both the examples shown and in the description hereinafter set forth 7 the reference letters used may refer to either the wooden window sash (Figs. 1 to 4) or the metal window sash (Figs. 5 to 8).

Referring to the drawings a is the window frame, 5 the outer casing and c the inner casing. (Z is the jamb lining. The opening sash f of the window is hinged to the sliding stile g by means of hinges i and the sliding stile in Figs. 1 to 4E, has projections g and 9 or equivalent, engaging in corresponding grooves in the sash frame and inner casing 0 so as to exclude wind and rain, while in the modification shown at Figs. 5 to 8 the sliding stile g has projections 9 and 9* engaging in corresponding grooves in the outer casing and inner casing respectively. A rabbet joint is also formed between the bottom 7' of the sash f and the sill at of the window frame. The sides and top of the sash f are protected by the outer casing boards 5 and at the opening side of the sash I provide (in the case of the wooden sash) a bead or projection f engaging in a groove 0 in the inner casing 0.

' Above the sash f I provide a space Z with sloped surfaces Z and Z at the ends thereof and in the space Z I place a sliding head m which'fills in the space which would otherwise be left above the sash top when the sash is in the closed position. The sliding head m is so beveled at its ends that the sloped surfaces Z and Z cooperate therewith to cause it to slide easily upward when the sash is raised so that when fully raised the sash can open freely inward over the top of the sill a When the sash is closed the sliding head m drops down again by gravity action.

The sliding stile 9 may be raised in any suitable way. In the example shown, Figs. 1 to 4:, the stile is raised by providing a rack 0% adapted to cooperate with a toothed lifting lever 0, which is turnably supported on a pin 0 secured to the jamb lining d.

This sash has the advantage of being perfectly secured and at the same time giving ventilation in rooms where it is not suitable to leave the window open.

Having now fully described my invention, what I claim and desire to secure by Letters Patent is In a window structure of the character stated with hinged and sliding sash, a window frainehaving-inclined'suffaees atthemOVementS Of'the seshfsubstantially as set '7 7 top thereof, a sliding head carried in-the forth. 10'
