This invention relates to improvements in windows of the kind in which provision is made for presenting the outer sides oi the panes to the interior of the building so that they may be cleaned with facility and without danger. Although not necessarily limited to windows oi this type, the invention is characterized by features which adapt it particularly to windows wherein the panes are carried by sashes which are moved in vertical planes as they are opened or closed.

One object of the invention is to provide a construction which will enable sashes of conventional design to be employed and which will permit said sashes to be opened and closed in conventional manner.

A further object is to provide a window of the kind generally described in which the sashes may be moved as a unit when it is desired to present the outer sides oi the panes to the interior of the building.

A still further object is to provide a window which is so designed that screens, storm sashes and other appurtenances which are more or less seasonal in use may be attached and detached with facility from the interior of the building.

A still further object is to provide a construction which is weather-tight.

A still further object is to provide a novel design and arrangement of the parts of the window whereby simplicity and economy in construction are obtained.

The invention is illustrated in the accompanying drawings in which:

Figure 1 is a view in elevation of a window embodying the features of the invention.

Figure 2 is a horizontal section taken along line 2-2 of Figure 1.

Figure 2a is a fragmentary sectional View taken along line Zit-2a of Figure 1.

Figure 5 is `a detail section taken along line 5--5 of Figure 3.

Figure 6 is a horizontal section taken along line 6 6 of Figure 4.

Figure 7 .is an enlarged fragmentary section taken along line 'I-l of Figure 3.

The window, as illustrated, includes upper and lower sashes I0 and II, respectively, which are of standard construction and which are mounted for movement in Vertical planes in a frame I2 so that they may be opened and closed in conventional manner, the said sashes tting in channels I3 and I4, respectively, which are formed in the vertical members I 5 and I6 of the said frame. Vertical members I'i provide the adjacent inner walls of the channels I3 and i4, the side walls of the said members being resilient and being bent inwardly at their outer ends to provide cam surfaces which co-operate with wedge-like strips I9. The members II (Figure '7) are secured to the frame i2 by screws 20 which enter threaded openings formed in the strips I9, the said screws being operative as they are tightened to move the said strips inwardly and hence to spread apart the side walls of the members Il. The screws 20,-- therefore, may be adjusted to cause the said side walls to engage the sashes I0 and II in such a manner that although, when unlocked, they may be opened and closed, at will, they will remain in any position to which they may be adjusted without the aid of weights. The marginal edges of the frame I2 which are located exteriorly of the building delimit an opening in which a screen a. (Figure 3), or any other similarly shaped appurtenance, may be arranged, the said screen, or appurtenance, tting against shoulders 20h and being removably secured in the said opening by suitable fastening means 20c.

The frame I2 is mounted in a rectangular casing 2I which is adapted to be incorporated in the wall structure of a building in conventional man-k ner, the bottom cross member 22 of the said casing being formed to provide a sill 22a upon which the bottom cross member 23 of the frame I2 rests. The sill slopes downwardly away from the interior of the building and is formed to provide a ledge 24 against which the cross member 23 iits. The vertical members I5 and I6 of the frame I2 are formed to provide flanges 25 (Figure 2) which extend substantially the full length of the said members, the outer ends of the said flanges preferably being formed to provide rounded edges 2l. 'Ihe vertical members of the casing 2l are indicated at 28 and 29 (Figure 2) and are channel-shaped in cross-section. They provide guides for sealing members 30 and 3|, respectively, which are likewise channel-shaped in cross-section, the side walls 32 of the said sealing miembers being formed to provide shoulders 33 which fit conformably against the rounded edges of the flanges 25 and rearwardly extending flanges 34 which slidably engage the opposite walls of the said casing members. Springs 35 which are carried by the casing members 28 and 2.9 are connected to the sealing members 30 and 3| and normally bias the latter so that the shoulders 33 thereof are held tightly against the rounded edges pies a position in which the head 38 thereof fits tightly against the upper cross member of. the frame I2 to provide a substantially weathertight joint.

The frame I2 is secured in the casing 2I by a Sleeve 42 and a spindle 43 (Figures 1 and 3). The

former is tubular in cross section; it is suitably' secured to the upper cross member 36 of the frame, preferably midway between the side members I5 and I6; it extends through an opening 44 which is formed in the head 38 of the sealing member 39; and it fits over the lower end of a trunnion which is suitably secured by a plate 46 to the upper cross member of the casing. The spindle 43 is suitably secured to the bottom cross member 23 of the frame I2, preferably substantially -midway between the side members I5 and I6; and it is journaled in a bushing 41 which is carried by the sill 22a.

Means is provided for reversing the frame I2 in the casing 2 I. The said means includes a roller 48 which is mounted upon a pin 49. The latter is carried by a sleeve 59 which fits over the spindle 43 and which is secured thereto by an element 5| which extends into an annular groove 50a formed in the said spindle, the said element permitting relative angular movement between the spindle and sleeve while preventing relative axial movement. The roller 48 rides upon a cam 52 which is carried by a shaft 53. The latter is mounted in a bracket 54 which is suitably secured in the lower cross member of the casing. It includes an extension 55 which projects through an opening 56 in the inner side wall of the said member and which carries a crank 51. When the parts occupy the positions shown in Figure 3, the roller 48 engages the lowermost portion of the cam 52. Upon rotation (in a clockwise direction), however, the cam 52 is operative to move the spindle 43, and hence the frame I 2, upwardly, the said cam being so designed that as its peak portion moves under the roller 48 the lowermost 55 portion of the lower cross member of the frame 4I2 is moved to a position slightly above that occupied by the top face of the ledge 24 of the sill. During such upward movement of the frame I2 a part of the spindle 43Y moves out of the bushing 41 while the sleeve 42 slides further over the trunnion 45. A second roller 58 engages the inner face of the cam 52, the said roller being carried by an extension of the sleeve 50. The roller 58 co-operates with the cam 52, as the crank 51 is operated to lower the frame I2, to insure return of the latter to its normal position in the event that the weightof the parts is inadequate for this purpose.

The upward movement of the spindle 43 is transmitted to the horizontal sealing member 39 in such a manner that the latter moves a greater distance than the frame I2, whereby when the said frame has been moved to the upper limit of its range of movementthere will be a clearance between it and the said sealing member. To this end levers 60 and 6I are connected at their inner ends to the pin 49 at opposite sides oi the sleeve 50. The lever 68 is pivotally mounted intermediate its ends upon a bracket 63 which is suitably secured to the sill-providing wall of the lower cross member of the casing. At its outer end the lever 60 is connected to the lower end of a link 64 which is arranged in the vertical member 28 of the casing and which is connected at its upper end to the outer end of a lever 65. The latter is arranged in the upper cross member of the casing and is pivotally mounted intermediate its ends upon a bracket 61 which is suitably secured to kthe top wall of the said casing member. The inner end of the lever 65 is` connected to a rod 68 vwhich is mounted between the front and rear walls of the sealing member 39 as best shown in Figure 3. At its opposite end the front and rear walls of the said sealing member carry a second rod 69 (Figure 1). The inner end of` a lever 10 is connected to the rod 69. The said lever is pivotally mounted intermediate its ends upon a bracket 12 which is suitably secured to the top wall of the upper cross member of the casing. The outer end of the lever 1II is connected to the upper end of a link 13-which is arranged in the vertical member 29 of the casing. 'I'he lower end of the link 13 is connected to the outer end of the lever 6I. y The latter is pivotally mounted intermediate its ends upon a bracket 15 which is suitably secured to the sill-providing wall of the lower cross member of the casing. n

It will be noted that as the spindle 43 is moved upwardly to raise the frame I2 the levers 60 and 6I are actuated to move the

links

64 and 13 downwardly, this movement of the said links being transmitted to the

levers

65 and 10 to raise the sealing member 39. The

levers

60 and 6I and 65 and 10 are adapted to move the sealing member through a greater range than is traversed bythe frame I2. 'Ihe sealing member 39, therefore, moves at a faster rate than the said frame. During its upward movement in the manner described the upper cross member 36 of the frame I2 moves out of the channel in the head of the sealing member 39 and at the completion of such movement is located a short distance below said head.

The downward movement of the

links

64 and 13 is utilized to move the sealing members 30 and 3I against the action of ther springs 35 to provide clearances between the said sealing members and the vertical members I5 and I6 of the frame. For this purpose the said links carry elements 16. The latter are adjustably secured to the said links by bolts 18 and have inclined faces 19 which engage downwardly and inwardly inclined projections formedl upon the end walls of the sealing members.

From the foregoing it will be apparent that by moving the crank 51 (in a clockwise direction) through an angle of approximately the frame I2 will be moved to the upper limit of its range of movement, in which position the lowermost edge of the lower member of the frame is located above the ledge 24 of the sill. Simultaneously with such movement of the frame the sealing members 30 and 3I move away from the flanges 25 of the vertical members I5 and I6 of the frame to provide clearances between, the said sealing members and the said frame members. At the same time also the horizontal sealing member 39 is moved upwardly to provide a clearance between, it and the upper cross member of the movement of the crank 51 clearances are provided between the vertical and horizontal members oi the frame l2 and those parts of the casing 2i which normally cooperate with said members to provide substantially weather-tight joints. When the frame i2 has been moved tothe position described, it is supported upon the spindle 133. As thus supported it may be rotated through an angle of 180 to present its outer side tothe interior of the building. When the frame l2 occupies this position the screen 26a may be removed and applied with facility from the interior of the building as may a storm sash or other similarly shaped appurtenance. Likewise the outer sides of the panes of both sashes may be cleaned with facility. The necessity for performing these operations from the exterior of the building is, therefore, avoided. Upon completion of the desired operations the frame l2 is rotated to its original angular position. The crank 5l is then moved in a counter-clockwise direction. During the return movement of the crank the frame l2 is lowered upon the sill of the casing behind the ledge 24 as shown in Figure 3. Simultaneously with the downward movement of the frame the sealing members Bil and 3i move toward one another and engage the flanges 25 of the vertical frame members as the frame comes to rest upon the sill. At the same time also the horizontal sealing member 39 moves downwardly with, but at a greater speed than, the frame i2 so that as the latter approaches the lower limit of its range of movement the upper cross member of the frame is caused to enter the channel 31 of the said sealing member. The construction described, therefore, is weather-tight and it has the further advantage that it does not interfere in any way with the normal operation of the sashes.
