In a sash lock window construction, a rail having inner and outer side walls and a longi tudinally extending bolt passage, said inner wall of said rail havinga slot, a lock bolt disposed in said passage and projected from one end, a lock case member engaged upon the outer side of said inner Wall, attaching- means securing said case to of the notch 44. In this Way the lock parts and the operating lever are at al1 times held against 10 said inner wall terminating between said case and the inner side of said bolt, and an operating looseness and rattling under pressure of the lever pivotally mounted in said case having an spring 48, the straddler member being so ar actuating lug extended through said slot into en ranged that it takes up all lost motion and com gagement with said bolt. pensates for wear and variations in the parts. 2. In a sash lock window construction, a rail This condition obtains even after considerable 15 having inner and outer side walls and a longi Vwear upon the parts and also under the con tudinally extending bolt passage, said inner wall tinuous vibration to which the parts are sub of said rail having a slot and a plurality of screw jected in the usual bus and car installations. ` The receiving holes, a lock bolt disposed in said bolt is retracted through downward pressure upon the lip 5B of the lever causing the lug 59 to swing 20 passage’and projected from one end, a lock case member engaged upon the outer side of said inner rearwardly in the slot 3D' and thus retract the bolt Wall, attaching screws connected between said against the pressure of the spring. inner wall and said case extending through said The lever 56 is in the form of a’ relatively wide screw receiving holes and terminating between plate, its forward edge being extended in a wide said case and the inner side of said bolt, and an curve from the forward edge of the lip 58 to the operating lever pivotally mounted in said case lug 59, so that in any position a substantial sur having an actuating lug extended through said face of the lever is eiïectually supported in the slot into engagement with said bolt. narrow space between the opposed parallel sur~ 3. In a sash lock window construction, a rail faces of the bottom rail and the sash lock case. It will be observed that the mounting structure 30 having inner and outer side walls and a longi tudinally extending bolt passage, said inner wall of the sash lock assembly is arranged entirely of said rail having a slot and a plurality of screw upon the inner wall of the bottom rail and at the receiving holes opening to said passage, a lock inner side of the sash lock bolt. Hence, it is bolt disposed in said passage and projected from unnecessary to punch slots in the bolt for receiv one end, an insert frame member engaged upon ing the threaded bushings and screws for the sash the inner side of said inner wall, a lock case mem lock assembly, as heretofore required. The flat ber engaged upon the outer side of said inner wall, face of the sash lock case provides a‘ relatively attaching screws connected between said insert large clear space between the lip 52 and the win member and said case extending through said dow sill so that there is little possibility of catch ing a ñnger between the casing and the sill in the 40 screw receiving holes and terminating between said case and the inner side of said bolt, and an lowering of the window. operating lever pivotally mounted in said case I have illustrated and described preferred and having an actuating lug extended through said satisfactory embodiments of the invention, but it slot into engagement with said bolt. will be obvious that changes may be made there in, within the spirit and scope thereof, as defined 45 JOSEPH SCHUNK, in the appended claims.
