  • lowerpane suspension members are provided with a slot and notch similar to the structure for the upper pane suspension members in which the end of the cable bearing a metallic sleeve 171 is entered and which sleeve 171 serves to retain the end of the cable in engagement with the member 170.
  • the member 170 extends substantially the full width of the track in the members 62 and 63 and is provided with a leg 172 which projects past the Weatherstrip in the tracks and engages in a box section opening provided in the lower rail 33 (FIG. 2) for positively coupling the lower pane of the double-hung window structure to the cable system of the invention, thus movement of either lower pane causes corresponding motion of the associated upper pane by means of the cables 158 and 159 as detailed above.
  • a lock as disclosed in U.S. Pat. No. 3,339,957 issued to R. M. Dallaire on Sept. 5, 1967 and in particular FIG. 2 thereof may be used.
  • This locking member is positioned over an inward facing flange shown as 180 in FIG. 2, and cooperates with the locking member of FIGS. 13 and shown as reference numeral 181 which is held to the jamb of the window by suitable means such as screws 182 and 183.
  • the cooperating member 181 is provided with a ramp surface 184 for urging the locking member away from the jamb during closing of the window and is provided with a retaining surface 185 for holding the lower pane, in locked position.
  • a feature of the double-hung window of the present inven tion is illustrated in F168. 13 and 14. It is desirable from time to time to remove the panes from a double-hung window for cleaning or maintenance purposes and with the counterbalanced system of double-hung window in accordance with the present invention, some means must be provided for retaining the upper panes of the window in closed position when the lower panes are removed.
  • Such means includes the movable stop member 190 shown in elevation in FIG. 13 and in cross section in FIG. 14, which is provided with an elongated pin 191 about which the stop member 190 may be pivoted.
  • a leg 192 is also provided on the stop member 190 adapted to be snapped into the track of the lower pane and permitting the suspension member 165 to rest against the horizontal surface of the stop member 190 to prevent the upper pane 27 from descending when the lower pane to which it is connected has been removed from the window.
  • FIG. 16 which is on the same sheet of drawings as FIGS. 14 and 15, illustrates a means in accordance with the present invention for covering the joint between two adjacent jambs of a curtain wall system of the present invention.
  • This jamb joint strip consists of an outer flat surface 200 with inwardly directed flanges 201 and 202 and a securing barbed flange 203 retained between the snap-on jamb covering extrusions 204 and 205.
  • a suspension system for providing counterbalanced operation of the panes said suspension system including, for each side of said window, a pair of cables, a pulley box mounted on the top end of the jamb track, a pair of journal blocks in said pulley box, each journal block being provided with a downwardly extending leg to be received within a recess in the jamb track and position said journal block with respect to the jamb track, a pair of pulleys journaled for rotationin each of said joumalblocks, the outer pulley of
  • connection means on the end of the cable including a metallic sleeve crimped on the end of the cable, and a moulded nylon paneengaging member having an opening therein and a slit extending upwardly from said opening, said metallic sleeve being received in said opening, said cable extending through said slit, said sleeve engaging the upper end of said opening to connect said pane-engaging member to said cable.
  • the pane-engaging member on the ends of the cables connected to the upper panes of said window is formed of two portions which may be adjusted with respect to each other, a first portion of said pane-engaging inembers being connected to the cable and having a series of laterally extending projections on one face thereof and the second portion of said member having a series of mating recesses, adjustment of said connecting means being obtained by varying the recesses in which said projections are inserted, said projections being a light force fit in said recesses.
