Specification of Letters Patent.

lpplicatin led September 26, 1919'. Serial I0. 326,661.

To all lwllfofrtz't may concern:

Be it known that I, AncHIE L. HUremN- soN, a citizen of the United States, and a resident ofthe city and county of San Francisco, State of California, have invented a .new and useful Improvement in Window- Frames, of which the following is a specification.

The object of my invention is to provide a window of the sliding sash type, the frame of which window is pivoted wlthin the casing or frame of the window opening, so that when lthe window is to be cleaned, it may be swung into the room for giving convenient access to both sides of the glass.

And thel further object of my invention is to provide means, in combination with the type of window mentioned whereby the crevices between the sash and the window-frame will be effectively closed, that is rendered Weather tight.

I attain my object by the construction illustrated in the accompanying drawings in which Figure 1 is a perspective of a window casing or frame housing the window opening, and having pivoted therein, on a vertical axls, centrally located, a swinging sash frame Erovided with the sliding sashes; parts being roken away to disclose structural features.

Fig. 2 is a plan section taken on the broken line 2 2 of Fig. l;

Fig. 3 is a section taken on the broken line 3--3 of Fig. l;

Fig. 4 is a detail ci a convenient type of means for pivoting the sash frame in the window frame;

Fig. 5 is a fragmental sectional detail on the broken line 5 5 of Fig. 2;

Figs. 6 and 7 are details of construction of the Weather-strip elements.

Fig. 8 shows a fragmentary perspective view of the lower right hand corner ofmy window frame as shown in Fig. 1, and-illustrates the provision of means connecting the overlapping weather strips eoperatively with each other, so that'they may be opened and closed together. i

a designates the window casing, or permanent frame housing the edges of the window opening; b, being the sill, and c, the lintel. This frame will be referred to as the window-frame to distinguish it from the sashframe al. The latter is pivoted in the window-frame by having secured to its u per and lower horizontalmembers, pivot p ates @,the pivots of which bear in socket-plates f, secured to the hntel c and sill b of the window-frame.

In the sash-frame slide the sashes g', h. The sash-frame may be made of metal as illustrated more clearly in Fig. 2; the stiles being formed as at i so as to provide vertical grooves for the sashes g, z, to slide in. The

stiles of the sash frame are made on the exterior with boxes j, or in other words with hollows' in which to vhang the weights c, connected by cords Z running over pulleys m l(see F ig. 5) with the upper and lower sashes, respectively; and balancing such sashes, as, usual, so they may be readily moved.

On the exterior of the boxes j, may be r0- vided box-like slots o forholding weat erstrips p. These are adapted-to bear on the sides of the window-frame so as to keep out the weather, the surfacesof the sides of the window-frame against which the weather-` strips p bear being concaved as shown at n, in Figs. 1 and 2, so as to provide a path for said weather-strips, and thus permitting and facilitating the rotation of the sash-frame in the window-frame.

In order to provide an effective closure of the crevices between'the adjacent members of the window-frame and the sash-frame position, that is in registration with the former, the sides of the window-frame are provided with vertical hinged weather-bars g and the lintel and sill thereof have horizontal hinged weather-bars r; and when the sash-frame is arranged in its normal position said weather-bars are so arranged as to bear against the sides and top and bottom of the sash-frame.

Weather-strip elements as g and r may be provided on both the inside and-outside of the window, since access to those on the outside is -readily obtainedthrough the window, by raising and lowering the sashes.

In order to assure eiiicient weather-tight construction, I prefer to cut away the exterior members d Vof the sash-frame at. their top and bottom ends as at s, so that the horizontal weather-bars 1' may be arranged in, and flush with, said cutaway ends, and the vertical weather-strip bars g may then be folded over the horizontal weather-strip bars 7' and said members d.

The hinges t may be of some convenient commercial spring-hinge type adapted for holding the weather bars q against the sideS sist of providing the hinge-pin t of the weatherstrip element g with a segment gear u meshing with a worm-screw c on Athe hinge-pin w of the weather-strip element fr.

I claim:

1. In a window, comprising a frame in the window opening, a sash-framepivoted for rotation vin said window-frame, and upper and lower sashes slidable in the sash-frame, boxes on the exterior of the ,sash-frame, means contained in said boxes by which the window sashes are suspended and balanced, weather-strip elements on the exterior of said boxes, and auxiliary weather-strip elements carried by oneof said frames and adjustable to cover the crevices between the adjacent members of the window-frame and 'the sash-frame.

2. In a window, comprising a frame in the window opening, a sash-frame pivoted for rotation in said window-frame, and upper and lower sashes slidable in the sash-frame, boxes on the exterior of the sash-frame, weights suspending and balancing the window sashes, the weights hanging in said boxes, weatherstrip elements on the exterior of said boxes, and auxiliary weather-strip elements carried by one of said frames and adjustable to cover the crevices between the adjacent members of the window frame and the sash-frame.

3. In a window, comprising a frame in the window opening a sash-frame pivoted for rotation in said window frame, and upper and lower sashes slidable in the sash-frame, boxes on the exterior of the sash-frame, weights suspending and balancing .the win-` dow sashes, the weights hanging in said boxes, weather-strip elements on the exterior of said boxes, weather-bars hinged to both sides and the top and bottom of the window-frame, and ada ted for being adjusted to overlap the yront faces of the lsides and the to and bottom of the4 sashframe, when the latter is in its normal position. l
