10 Claims.

This invention relates to double sash windows and particularly to a manner of mounting such windows so that they may be readily washed on both sides from the interior of the building. Such 5 windows are shown for instance in my Patent No. 1,687,116, dated October 9, 1928, but these windows were of the reversible type and I found that it was somewhat difficult and awkward to manipulate the same, especially with large and heavy windows.

Also, this arrangement required a certain remodeling of the window casing structure.

tions.

The weight of sash windows, as is well. known, is counter-balanced by weights and an-.

other object of my invention is to arrange the structure so thatt e weights be utilized to help support the windows when-they are tem porarily changed to the easement type. This is of especial advantage in large windows in'which their weight would otherwise tend to make them sag and tear away from their connections whenswung inwardly.

Another object is to provide a structure for the purpose arranged to be easily applied either to new construction or on windows already in place.-

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following.

Referring now more particularly to the charactersoi reference on the drawings, the numeral 1 denotes in general the casing for the double The win dows are spaced apart transversely of the casing and said casing is provided with guide beads i between the windows partially counter-sunk in the casing and with inner beads 5 bearing flatly against the casing. lhe lower portion ia of the right hand intermediate bead, for a length greater than the height of the sashes, isremovable. It is held in place at its lower end by its usual socketed fit in the casing and at its upper end by a swing clamp 6 pivoted on the fixed bead above, as shown in Fig. 15.

Similarly, the lower portions to of both the inner stops are removable from their upper portions and from the casing. They are removably secured in place by hand screws 7 turnably mounted on plates 8 secured to the stops and projecting through the same for engagement with tapped sockets 9 driven into the casing, as shown in Fig. 14. Removal of these stop portions enables thev windows to be moved inwardly when both sashes are lowered to the same level, as will be evident.

The cords 10 of the usual counter-weights 11 on the sash show-' i the right hand side of the sashes are provided on their free ends with enlargedheads 12. Each head has detachable engagement with a slotted socket member 13 set in the corresponding sash frame at the bottom of the cord groove 14 in the edge of said frame, as shown in. Figs. 16 and 17.

The outer sash 3 has horns 15 depending from its lower corners as usual these are cut off as necessary as indicated in Fig. 11 so that the bot- 10 tom of the horns is on a level with the bottom of the inner sash when the tops of the sashes are on a common level. hand horn a plate 16 is securely attached, from which a pivot pin 17 dependsyas shown in Fig. 11.5 11; this pin being as near the inner and left hand edges of the window as possible.

In the lower left hand corner of the inner sash 2 is mounted a vertical socketli; also close to the left hand and inner edges of the sash. A pin 29 19 is slidable in this socket, being connected to a clamping screw 20 whose head rides in a vertical slot in the socket and which is exposed to the inner face of the sash, as shown in Figs. 12 and 13. This pin is arranged so that when in its lowest position it depends to the same level as the pin 1'7; and whenraised to its limit it will just clear the bottom of the sash. The clamping screw 20 or any other equivalent device enables the pin to be rigidly held in either position.

On the upper edge of each sash frame at the left hand corner is fastened a plate 21 from which a pivot pin 22 projects upwardly in vertical alinenient with the corresponding lowerpin. Fig. 8 shows a permanent installation. If a deg j'itachable installation is desired the plates 210.

having the upstanding pins 22a thereon are removable; each plate being seated on the top of the sash and located place by side and end flanges 23. The plate is reinovably secured in :3 j place by a hand screw 24 mounted on a yieldable strip 25 secured to the plate; said screw being adapted to engage a tapped socket 26 sunk in the top of the sash. This arrangement is shown in Figs. 9 and 10. The presence of these gr; pins whether detachable or permanent does notinterfere with the opening or closing of the windows in the usual way. .Their purpose-is to serve as pivots for the windows about which the latter may swing inwardly, when said pivots are sup- EQ- I' ported as follows:

Adapted to rest on the window sill and to straddle and detachably secured to the adjacent vertical portion of the window casing is a C clamp 27 having a pair of blocks 28 mounted on its up-v per surface for separate transverse adjustment, to serve for different thickness of sashes. The upper surface of the blocks is provided with slots 29 and 30 in which the lower pins 19 and 17 respectively of inner and outer sash ride. The slot 29 extends transversely of the window in an inward direction and is arranged so that the inner sash when swung inwardly and with the pin at the inner end of the slot, offers no interference with the full inward swinging movement of the Touter sash, as shown in Fig. l. The slot 30 is arranged so that the outer may be swung inwardly, when its pivot pin is moved along the slot, without interfering with the adjacentintermediate bead 4 or w h outer weather strip '31 on the casing.

- The inner ends of both slots are provided with short reverse bends B to receive the pivot pins and hold them against an undesired tendency to return to their normal positions at the opposite ends of the slots.

'vided as an integral part of said clamp.

To the bottom of the left Adapted to be disposed above the sashes and to be clamped against the casing is a similar 0 clamp 32 having slotted blocks 33 adjustably mounted on its under surface to receive the upper pins; the slots being of course the same length and having the same slope as those of the lower clamp. To support this clamp in a definite horizontal position an upstanding bar is pro- A pair of transversely spaced circumferentially grooved pins 34 project toward the window casing from the bar. Said pins are adapted to enter vertical keyhole slots 35 provided'in a plate 36 secured to the casing and extending under the intermediate bead 4 011 both sides of the same, as shown in Fig. 6. The plate slots are arranged so that their large ends are uppermost and receive the heads of the pins, the lower narrow'portions of the slots engaging in the pin grooves, shown in Fig. 5. When the pins are at the bottom of the slots the clamp blocks 33 are supported at the proper level to engage the upper sash pins.

In operation the removable stop portions are first withdrawn. The lower clamp 27 is then mounted in position under the sash and said sashes are then lowered so as to cause the bottom pins to depend into the corresponding slots in the clamp blocks. The blocks are initiallyadjusted if necessary so that their spacing corr sponds to the transverse spacing of the sashes. Independently the transverseialineinent of the clamp as a whole may be assured by the fact that the outer clamping screw 27a of the clamp is only used to make an initial adjustment i the position of the clamp; while the inner clamping 1 and engaged with the upper sash pins; any necesi sary adjustments. of the clamp or its blo as being of course first carried out just as was the case with the lower clamp. The sashes are then separately swung inwardly a short distance so as to expose the cord connecting members in the edges of the sashes and allow the cords to be disengaged. The sashes may then be swung the remaining distance, an inward pull being exerted at the sametirne'so as to cause the pins to travel along the slots until they engage the reverse bends B. The outer surfaces of the windows are then exposed to the interior of the building and are conveniently positioned for washing.

If the windows are large and heavy I utilize "the counter-weights to aid in supporting the weight of the windows in the following manner:

Swivelly connected to the bar 32a are the end blocks 37 of a pair of block and tackle units. The other end blocks are provided with hooks 38 adapted to engage slotted plates 39 secured on top of the sash frames over recesses 40 out therein, as shown in Fig. '7, intermediate the right and left hand sides of the sashes. The free ends of the cables 41 of the block and tackles are provided with hooks 42 adapted to detachably engage with the heads 12 of the counter-weight cords, as indicated in dotted lines in Fig. 1, when such heads are disengaged from the windows as previously stated. The weights thus act on the block and tacklesv to draw the blocks together and thus yieldably support the sashes in the horizontal position as swung inwardly, without tending directly from their top pulleys to the sashes and which would cause a severe binding, besides being in the way.

cords To prevent possible accident the clamps are tied together by a chain or flexible cord 43. The weight of the upper clamp acts as an anchor for the lower clamp while the latter is being applied and in case it should slip out of the Window, and

vice versa.

While each sash preferably has a complete set of pivot pins of its own, one pair of clamps will serve for all the windows of the same size in a sin le building and can be adjusted for all the sizes, while one adjustment of such clamps will of course serve for all the windows of agiven size.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
