WINDOW.

Application filed May 12, 1925. Serial No. 29,661.

This invention relates to a window comprising a frame and l'owerand upper sashes slidable vertically in the frame between guides on the upright members of the frame,

said uides performing the functions of the usual stop bea is and parting beads of an ordinary window of this type.

The chief object of the invention is to provide a window, the sashes of which are provided with countcrbalancing mechanisms, causing them to remain in various positions to which they are movable, and are adapted to be swung into the room with the counterbalancing mechanisms. so that the glass may be conveniently washed the room, and the sashes and the counterbalancing mechanism may be rendered operative by the operation of restoring the sashes to a vertical position.

I attain this and other related objects by the improvements hereinafter described and claimed.

The frame of a window embodying my tion and material. The upright members 20 of the frame are provided with inner and outer sectional guides for the lower sash 2'1 and the upper sash 22. The inner guides perform the function of the usual stop beads which guide the lower sash, and each is composed of an upper section 23, fixed to the frame, and a lower swinging section 241, hinged at its lower endto, the frame, preferably by a pin or screw 25 (Figure The 'wvinging sections are adapted to swing inward from the frame, as shown by Figure 2. When the swinging sections 24 are upright,

their upper ends, which are preferablyserted in a recess in the inner face of the frame, and a key composed of a shank 27 (Figure 9), having-a hook 28 and a. head 29 adapted to turn in a recess in the inner face of the swingingguide section 24. The hook is passed through the slot in the plate 26, and the shank is then turned to cause the hook to bear on the inner side of the plate, so that the swinging section is locked to the fixed section.

A counterbalancing mechanism is carsash 21, and is adapted to maintain the Said mechan able on the guides.

fixed to the swinging sec 1 time at, a jewelries; a hearings. as

(Figure 4-") at opposite ends of a cavity 34 in the bottom rail of the sash, gears 35 fixed to the shaft and meshing with the racks, and a. torsion spring 36, fixed at 37 to the shaft, and at 38 to the sash, 01' to one of the bearings 33, and maintained at a suitable tension, to act through the gears and racks in preventing movement of the sash by gravity, when the sash is upright, the tension of the spring being such that rotation of the shaft and gears is permitted when the sash is forcibly moved up and down.

I prefer to make the torsion spring in two independent parts or sections, each fixed at one end to the shaft, and at the other end to the sash, so that in the event of breakage of one part, the other will continue operative.

The swinging sections 24 are longer than the sash as shown by Figures 1, 2, 4, 5 and 7, so that said sections, the sash, and the counterbalancing mechanism may be displaced or swung inward as a unit. as shown by Figure 2. to permit the washing of the glass, the operativeness of the counterbalancing mechanism being unaffected by this displacement. The combined length of the guide sections 23 and 24 is such that when the sections are in alinement with each other, the sash 21 may be raised to the top of the frame.

The upright sides of the sash 21 are provided with plates 40 (Figures 4, 5 and 10) having cars 41 (Figure 10) confining the sash in sliding contact with the racks 31, the swinging sections '24 being provided with grooves 42. into which the cars 41 project. Provision is thus made for so engaging the swinging sections with the sash as to prevent independent swinging movement of either section, the sash and its plates 40 constituting a connection between the two swinging sections. V

The sash may be locked against endwise movement on the swinging sections by the engagement of alocking dog 43 (Figures 5 and 10) with teeth of one of the gears 35. Said dog is slidable in a groove 44, in an upright stile, and may be manipulated when the sash is swung in aid to engage a gear, and thus prevent rotation of the gears and sliding movement of the sash.

I preferably provide restraining means, adapted to support the swinging end of the sash when it is swung inward, and thus support the sash in a desirable position for washing. Said restraining means includes pulleys 46 (Figure 6) journaled on fixed studs 47 in recesses in the frame, springs 48, fixed at 49 to the studs, and at 50 to the pulleys, and tethers 51, fixed to the pulleys and the sections 24-. The springs are adapted to rotate the pulleys in the direction required to wind the tethers, so that when the sash is upright, the tethers are taken up by the pulleys. hen the sash is inclined inward the tethers are unwound, and the springs are tensioned so that the tethers support the swinging end of the sash against downward movement from any inwardly swung position in which it may be left. The tethers may be lengths of wire cord.

The upper sash 22 is slidable between inner guides performing the function of the usual parting beads, and the outside stop beads 53'} (Figure 2) with which the upright members of the frame are provided. Said inner guides are shown by Figures 11 to 17, and each includes a fixed upper section 54 (Figures 11. 14 and 15), a fixed lower section 55, and a swinging intermediate section 50. The swinging intermediate sections 56 are connected by hinges 58, with the fixed lower sections 55. the swinging sections being adapted to swing inward, as shown by Figure 11, and by dotted lines in Figare 12.

\Vhen the swinging sections 56 are upright. their upper ends, which are preferably bevelled, abut against the lower ends of the fixed upper sections all the sections being in alinement with each other and constituting continuous guides.

The swinging sections 56 are releasably secured, to the fixed upper sections 54 bv detents, including bolts 5.) (Figures 14 and 15) slidable in vertical guides tit) in the upper sections, and sockets G1 in the swinging sections, adapted to receive said bolts, the latter be ng movable by handles (32 projecting through slots 3 in the upper sections.

A counterhalancing mechanism is carried by the swinging sections 56 and the upper sash 22. and is adapted to maintain the sash at different positions to which it is movable. Said mechanism is in all essential particulars like that above described in connection with the lower sash 21 and the swinging sections 24. and includes racks 64. fixed to the swinging sections 56. a shaft (Figure 11) journaled in hearings in a cavity in the bottom rail of the upper sash, gears 66 fixed to the shaft and meshing with the racks, and a torsion spring 67, shown by dotted lines in Figure 12. fixed to the shaft and to the sash, and operating like the spring 36 already described.

'The swinging sections 53 are longer than the upper sash, as shown by Figure 11, so that said sections, the sash, and the counterbalancing mechanism may be swung inward as a unit, after the inward swinging of the lower sash. The combined length of the sections 54, 55 and 56 is such that when the sections are in alinement with each other, the upper sash may be lowered to the bottom of the frame.

To ensure the operativeness of the counterbalancing mechanism when the upper sash is completely lowered, I provide the lt tl fixed lower sections 55 with racks 64* constituting extensions of the racks 64, as shown by Figures 12 and 13, and meshing with the gears 66, when the'bottom rail of the upper sash is below the hinges 58, connecting the lower and swingingsections.

The swinging end of the upper sash may be restrained by means similar to the means described in connection with'the lower sash, and including tethers 51 connected with spring pulleys 46 on the frame and with the sections 56.

The arrangement is such that when the lower sash and the swinging sections 24 are displaced inward, the upper sash and the swinging sections 56 are free to be similarly displaced, the sections 56 being adapted to swing under the fixed upper sections 23. T he upper sash may be mo to project inwardly from the sections 56, as shown by Figure 11, to facilitate washing.
