ALBERT KIEKERT, OF HEILIGENI-IAUS, GERMANY.
Application filed October 7, 1913.
To all whom it may concern:
Be it known that I, ALBERT KIEKERT, a subject of the German Emperor, residing at Heiligenhaus, Prussia, Germany, have invented an Improved Window-Closing Mechanism, of which the following is a specification.
This invention relates to a window closing mechanism more particularly adapted for casement sashes, which are hung upon hinges so as to open and close like doors.
The novel closing mechanism may be.
readily installed, is of superior strength, may be easily manipulated and is entirely concealed from view.
In the accompanying drawing: Figure l is a face view of part of a casement sash provided with a closing mechanism embodying my invention; Fig. 2 a vertical longitudinal section thereof; Fig. 3 a left hand end view; Fig. 4; a right hand end view; Fig. 5 a cross section on line AB Fig. 1; Fig. 6 a cross section on line CD Fig. 2; Fig. 7 a cross section on line E-F Fig. 2; Fig. 8 a cross section on line G-H Fig. 2; Fig. 9 a cross section on line JK Fig. 2; Fig. 10 a longitudinal section through the bolt and adjoining parts, and Fig. 11 a cross section on line LM Fig. 10.
lhe right sash A is provided along its free vertical edge, with a longitudinal groove, in which is rigidly fitted, a rail a which is U shaped in cross section, and is so arranged that its shanks extend inwardly or toward the hinged end of the sash. Rail a incloses a slide 6 which is also U shaped in cross section, but is so arranged that its shanks extend outwardly or toward the free end of the sash. Rail a is secured to the sash by screws on that pass through slots 9?. of slide 6, while the latter is guided by pins Z extending inwardly from rail a and likewise passing through said slots. Within the hollow of slide 5 there are accommodated a Specification of Letters Patent.
Serial No. 793,865.
plurality of bolts 6, that turn on pivots e which pass through slots of slide 6 and are journaled in rail a. Bolt 6 carries on its free end, a roller r, and is provided with a pair of projections 6 adapted to be operatively engaged by a pair of apertures 0 formed in slide 6. To the latter there is also rigidly secured a rack 2 adapted to be engaged by a toothed collar 2 fitted on the spindle e of the operating grip 2 The left sash B is provided opposite each bolt with a socket or keeper 0 adapted to be engaged thereby. On turning grip a in one direction, rack a will operate slide 1), which in turn will swing bolts e outwardly to engage keepers and thus lock the sashes in their closed position. On turning grip 2 in the other direction, the bolts will be retracted as will be readily understood. In lieu of using pivoted bolts, rail 1) may be provided with integral or rigid bolts 6 that engage correspondingly constructed keepers of sash B.
1. A casement sash having a longitudinal groove at its free edge, a U shaped rail fitted therein, an oppositely disposed U shaped slide encompassed by the rail, a bolt operatively engaging the slide, and means for operating the slide.
2. A casement sash having a longitudinal groove at its free edge, a U shaped rail fitted therein, an oppositely disposed U shaped slide encompassed by the rail, a bolt pivoted to the rail and engaged by the slide, and means for operating the slide.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
topics of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
