UNITED s'rA'r s PATENT OFFICE.

RICHARD B. BROWNE. OF BROOKLYN, NEW YORK (BASEMENT-WINDOW.

To aZZ whOm it may concern:

Be it known that I, RICHARD B. BROWNE, acitizen of the United States, residing at Brooklyn, New York, have invented certain new and useful Improvements in Casement- Windows, of which the following is aspecification.

One of the objects of the invention is to provide, in connection with a casement window, a substantially full openin and to permit the sash glasses to be was ed on both sides from within the apartment in which the window is installed. I

Another object is to provide in connection with vertically arranged sashes, improved supporting and guiding means therefor.

A further object is to construct and arrange the sash controlling operating linkage to support the weight of the sashes.

A further object is to provide improved means for retainin the sashes in various open positions an for locking them in closed position.

Other objects and advantages of the invention will be sufficiently described here after in connection with a detailed description of the accompanying drawing, which shows the best form of the invention which has up to the present time been devised. It is to be understood, however, that the invention is capable of embodiment in other forms, and I do not limit myself to details except as claimed.

Figure 1 is an elevation of a window em bodying the invention, the point of View bea ing from the side of the window, which is usually the inside,according to the preferred manner of placing the window in a building. Fig. 2 is a" side elevation of'the same, with the sashes in partly open position. Fig. 3 is a top plan of the same. -Fig. 4 is a horizontal section, enlarged, on the line 4-4 of Fig. 2. Fig. 5 is a vertical sectional detail of the handle and latch mechanism." Fig. 6 is a fragmentary enlarged elevation of one of the common link pivots. Fig. 7 is a vertical detail of the top part of a sash and frame particularly showing weatherproofing features. Fig. 8 is a sectional detail at 88, Fig. 1. Fig. 9 is a sectional detail of the bottom part of the frame of one of the sashes showing a part of the retaining means for holding the sashes in various open positions. Fig. 10 is a detail of another part of the sash-holding means.

The frame F comprises side members, f,

sill f and lintel f. A substantially central mullion M is also usually provided. The sashes S, S .are hinged together at their meeting edges at 11. The free edges of the sashes at top and bottom move in close proximity to beads 12 provided on the sill and lintel. In some cases the edges 13 of the sashes proper may engage or move in close proximity to these beads. In other cases, other members, later to be described, may

have such engagement with or proximity to the beads.

At a suitable place or places, usually near the top and bottom of the window, are provided combined guiding and supporting links or arms 14. These arms are arranged in pairs and of each pair the inner ends are connected or hinged at a common point 15, usuallly located upon the mullion. The outer ends of the links of each pair are pivoted at '16 to the sashes, midway between their outer edges and the hinge point 11. At

different points in their length the arms 14 are made of suitable vertical-dimensions to properly support the weight of the sashes. As seen in Figs. 1 and 6, near the common hinge point 15, the arms have relatively great depth, and the length of the bin es is also suitable for the proper support 0 the weight imposed upon them. The arms may be reduced in vertical dimension as they approach the sashes.

The arms, sashes and pivot connections are suitably designed so that as the sashes are moved their hinge connection 11 moves in a line perpendicular to the horizontal center of the frame; that is, along a line perpendicular to the frame at the point 15,

while the free edges of the sashes move in the same straight line along or close to the beads 12. Thus when the sashes are fully opened they lie close together and approximately perpendicular to the frame at the center thereof. In closing, the sashes move uniformly in relation to each other and to the frame, until when fully closed they are in line with each other and the window opening is completely closed.

To insure the proper motion of the sashes, it is essential that the parts of the linkage (including in this term the sashes themselves) shall conform to requirements of a movable parallelogram; that is, each of the links and the part of the sash opposite to it, between the point 16 and the point 11, should be parallel and of the same length,

and the part of the sash between the point 20 and the point 16 should be of the same length. The point 15 and theparts of the sashes that are in proximity to the beads 12 should also be in line at all times. To produce this result, the hinge pins 15 are located substantially in a line with the outer faces of the beads 12 and parts of the mullion at 17 are cut away to accommodate the arms 14 when the window is closed. The pins of hinges 16 are also recessed into the sashes so that they are directly in line with the free edges of the sashes and the hinge pins 11. The hinge points 16 are also carefully located midway between hinges 11 and the free edges of the sashes. Eyes 18 on arms 14, which engage the pins of hinges 16, are also offset or arranged at one side of the arms so that when the window is closed the arms may lie parallel to and against the sashes.

It will thus be understood that in all the movements of the sashes the linkage, comprising the arms 14, properly guides the sashes and at the same time the arms entirely supportthe weight thereof so that no part of the sashes engages frictionally with any part of the frame. The sash movement is therefore exceedingly free and accurate. At the same time in' most positions the sashes are self-braced against wind pressure and especially lateral wind pressure. To prevent accidental movement of the sashes,

. as for instance by wind pressure when the sashes are in approximately the position of Fig. 4 or between that position and the fully closed position, especial means may be provided.

One or both of the sashes at top or bottom, but usually at the bottom, is providedwith a holding member 20 and this member is usually yieldable. For this purpose the member 20 may be bolted or otherwise secured to the edge of the sash at 21 and may be free from the sash for a suitable distance at 22. By the use of a suitabletool this free part of the holding member may be bent outwardly slightly to bring it into proper relation to bead 12 or to the movable latch or detent. This detent is a strip 23 hinged to head 12 at 24 and provided with serrations or notches 25 to cooperate with the yieldable end of holding piece 2O. WVhen the sashes are in proper position detent 23 is swung up from the position of Fig. 9 and into engagement with holding piece 20 and thus the sashes are positively locked in position and secured against any accidental movement due to wind pressure or other cause. If any looseness develops as between the detent 23 and the holding member 20 it may be taken up by slightlv bending out the free portion of the holding member.

A suitable latch is provided for holding the window in closed position, and this is dle. For this purpose, in a preferred embodiment, a bolt 26 is movably mounted intheunullion and urged to active position by spring 27. The operating handle 28 is pivoted to one of the sashes and is also pro vided with a latch 29 to cooperate with bolt 26. When the sashes are partially closed, the handle may be easily grasped and by pulling it straight in the sashes are fully closed, and then by moving the handle laterally latch 29 is engaged with bolt 26 and the window is securely locked against open mg from the outside.

Suitable weatherproofing features are provided as follows: Along their meeting edges one of the sashes is recessed as at 30 and the other is provided with a bead or flange 31 to enter the recess. A strip of felt 32, or other suitable packing, is also placed along the edge of one of the sashes to be engaged by the other and complete the weatherproofing along the vertical meeting edges.

The lintel f is provided with a drip strip 33 extending out beyond the sashes when erstrip 36 of meta or other flexible mate-' rial to engage the vertical web of the frame member when closed. This Weatherstrip serves to carry off to the sides of the sashes any water which may get between the lintel and the sashes.

At the bottom the sashes have a flange 38 to cooperate with a. suitable recess in the sill and the lower edges of the sashes are also provided with strips 39 to engage beads 12 or packing 40 carried thereby.

The vertical members of the frame are usually of channel section and at the bottom of the channels are located packing strips 41, and these are engaged by free edges 13 of the sashes. The outer faces of the sashes are recessed at 42 to avoid interference between this part of the sash and the flange of the frame member in the first part of the opening movement. This is quite important because evidently the first opening movement of the sashes causes an outward movement adjacent to the points 42, and without suitable recessing there would be more or less interference with the frame at this point.
