Fig. 15 is a sectional view taken atline XV-XV in Fig. 14. v In practising my invention, I provide a pair of sashes, each slidably guided in suitable grooves at its sidsin the framework of window, and a sash-cord'secnred at the ends to the sidesof the respectivesashes, forming an openloop ending Vat the respective sas-hes. The cord extends past a pair of stationary guide rollers mounted 'inlthe upper portion of the framework and also a movable guide roller intermediate the two stationary rollers. The movable roller Vis mounted on a weighted `member, which Vis movable up and down within a side chamber in the framework, and is adapted to'be releaably restrained from the movement, at wi.
"In order to facilitate a better understand-v i ing ofrny invention, the following descrip` 'I Vgivenl with reference to the drawings. Referring particularly to Figs. 1 to 7, a window embodying my invention comprises, in general, a rectangular framework 1, having plurality of longitudinall grooves 2 in each of its vertical sides, and an innerand an outer sash 3 and Lfor holding window glasses therewith and adapted to slide up and down along the vertical grooves 2 with their vertical side edges guided thereby. y
. At vthetop portion of each vertical side of the framework 1, there are provided three stationary pulley orguderollers 5, Gand 7. 'l1-if@ 6- formsa @Operating pair. 0frQ11- ers with another stationary guide roller 8, and a wire rope 9 is stretched between the pair of rollers 6 and 8, carrying a weighted member 10, to which the rope ends are secured by suitable means as shown at 11 and 12. The rollers may have peripheral grooves. The counter-weight 10 is adapted to travel up and down within a vertical side chamber formed in the framework 1 behind its grooved side.
f Another rope or saslrcord 13 is also provided extending between the inner and outer sashes past the stationary rollers and 7, and a movable roller 14 mounted on the counterweight 10.
Each rope 9 is operatively engaged by a restraining device 15 conveniently arranged in the lower portion of each side chamber, for releasably restraining the rope 9 and consequently the weight at any desired vertical position. In Figs. 6 to 10, the device may comprise a pair of brake-shoe members 16 pivotally mounted on a stationary part of the device at their lower ends and disposed 'around the roller 8 together with the portion i of the rope 9 passing therearound so as to embrace the same. The shoes may be curved i near their free ends to permit the rope 9 to pass freely, and also may have horizontal holes therein substantially registering with each other and operatively engaged by a lever 17 extending through the holes and pivotally mounted on a stationary part of the device at a pin 18 between the free ends of the shoe members 16.
The other ends of the levers 17 at both sides of the framework extend laterally and down-- wardly, and are operatively connected to the respective ends of an operating rod 19 extending along the bottom side of the-framework 1. The rod 19 carries a member 20 secured thereto intermediate the ends. The member 2O is provided with a cam surface 21, adapted to cooperate with the inner end of a handle lever 22 pivotally mounted on the frame-work bottom by means of a pin 23.
It will be readily seen that, with the position shown in Fig. 6 of the handle lever 22 and the rod 19, the shoe member 16 is held in its released or inoperative position, and permit the free vertical movement of the rope 9. lVhen the handle 22 is operated to the oppo siteposition, that is, actuated in the counterclockwise direction, the rod 19 is pulled to and held in the left hand position, forcing the lever members 17 at the respective ends in the clock-wise direction, and a braking effect is applied on the ropes 9 and the rollers 8, thus restraining the ropes 9 and consequently the weighted members 10 from their vertical movements.
p Now it is assumed that the brakes are applied on the respective ropes 9 at an inten mediate height of the weighted members 10, as shown in Figs. 1, 2 and 3. Then the movable rollers 14 assume the corresponding` fixed of the former sash, and they may take positions as shown in Fig. 3.
In order to move both of the sashes 3 and 4 upwards or downwards Simultaneously or jointly, the brake devices may be released to permit free movements of the weighted members 10, and the sashes can be moved jointly to any desired height, for example, the upper-most position as shown in Fig. 4. In this case, the Weight-ed members 10 function .as the counter-weight for the both sashes combined, as they are now suspended from the sashcords 13.
With the suspended state of the weighted members, each sash 3 or 4 may be operated individually and it will assume any desired position independently from the other, as the weighted members will be lowered or raised half the distance travelled by the individual sash by aid of the movable pulleys 14.
Since the weightedv members 10 are restrained from lateral movement or vertically guided by means of the stretched wire ropes 9, the sashes can slide up and down very smoothly. The tension of the rope 9 may be adjusted by the screw threaded member 12 extending through the bottom portion of the member 10.
If desired, the weighted member 10 may be made variable in weight. For this purpose, a frame or casing of the member may be provided with inwardly projecting portions 31 on the opposite inner surfaces thereof, and a plurality of weights or poises 32 so formed as to interfit the projected surfaces of the frame 30 are carried within the frame 30. By changing the number of poises 32 carried within the frame, the whole weight ofthe member 10 can obviously be varied.
In order to secure a positive application of the brake devices 15 on the ropes 9 passing around the roller 8, the brake-shoe member 16 may have a somewhat round groove 14 in order to closely fit the rope periphery as shown in Fig. 10. The round grooves 14 can also prevent unnecessary strain of the wire f.
In the above embodiment of my invention, I have shown the restraining device 1 5 as a brake-shoe-type, but any other type of device may be used in substitution therefor, because the construction of the restraining device does not constitute any essential feature of my invention. For example, I may replace the device with that shown in Fig. 13 somewhat diagrammatically. The modified form lli'i Cir limitaba of restraining device comprises members 51 and 52, pivotally mounted on pins 53 and 54 which are fixed within the framework 1. The free ends of the pivoted members 51 and 52 are respectively provided withrecesses 0ppositely registering with each other forming a space permitting the ropes 9 passing therethrough. The other ends of the levers 52 are respectively connected with rods 55, the other adjacent ends of the rods 55 being connected with a lever member 56 which may be located intermediate the lower corners of the framework 1.
The lever member 56 may be pivotally mounted on a pin 57 and ing handle, not shown, is provided for operating the lever 56 about the pin 57. The lever member 56 may be provided with angularly disposed surfaces 58 and 59 which cooperate with a spring member 60, in order to hold the lever 56 in predetermined positions after being operated in either direction. v
As will readily be noted, when the lever 56 is actuated and held in the position shown, the
In Figs. 14 and 15, a modification is shown, in part, somewhat diagrammatically. In this form of my invention, the guide rope 9 in each side chamber of the framework 1 is replaced by a link structureA 70. The structure may comprise a pair of levers 71 and 72, respectively pivoted in the upper and lower end portions of the weight chamber on the I axes 73 and 7 4 respectively located therein by suitable bearing means, such as 75 and 76.
The respective ends of the levers 71 and 72 are operatively connected by a pair of vertical links 77 and 78. The lower lever 72 is provided with an arm portion, at the outer end of which one end of a rod 79 is operatively connected therewith. The rod 79 has a function and arrangement similar to the rod 19 in Fig. 6, and a similarlink structure, not shown, is connected to the other end of the rod 79.
The weighted member 10 is provided with side grooves 8O and 81 adapted to receive the inner edge portions of the links 77 Yand 78, re'- spectiveiy. The member l0 carries at the a suitable operatn a pair y of sashes bers,
fdis'tance therebetween, and thelink edges will@ closely" engage the `grooves. 80 andA 81 with? alfsuiiieient pressure thereon-to restrain the weighte'dmember 10.` from its vertical movements When the rod7 9 'is actuated to theri'ght, the'braking action on the weighted member '10 will bellreleased', aswill be read ilyf/understood. Vvith thisarrangement, the
window'- sashes may' bel operated to slide up andf: down either individually or j ointlyg and alsolthe weightedmembersflO may bepro'perly'guidedby the links 77 andv 7 8, enabling smooth operations of the sashest AAlthough I have shown particular` embodiments of my invention, it will be obvious to those skilled in the art that various modifications and changes may be made without departing from the spirit and scope of the invention, and I do not desire to limit the invention to the specific modifications described, but only in so far as set forth in ,the appended claims.
