SPECIFICATION forming part of Letters Patent No. 392,924, dated November 13, 1888.
Application filed December 2T, 1837. Serial No. 258,952. (No model.)
.To @ZZ whom it' may concern:
Be itxknown that we, HENRY S. KLEIN, of Milwaukee, in the county of Milwaukee, and in the State of i/Visconsin, and HENRY E. KLEIN, of Chicago, in the county of Cook and State of Illinois, respectively, have invented certain new and useful Improvements in Windows; and we do hereby declare that the following is a full, clear, and exact description thereof.
Our invention relates to windows; and it consists iu certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.
In the drawings, Figure 1 represents a front elevation of our invention, partly in section; Fig. 2, a partial vertical section of the window-frame; Fig. 3, an edge View of the sash; and Fig. 4, a horizontal section on the line 4 4., Fig. 1. Figs. 5, 6, and 7 are detail views of a latch that forms part of our invention.
Referring by letter to the drawings, A A represent the side pieces of a window-frame that forms part of ourinvention, and each of these side pieces is provided with a vertical channel, B, for a concave guide-strip, C, the latter being preferably of metal and located between the binding-strips D for the window-sash.
Each stile E of the window-sash has its outer edge out out-to form a groove, F, that gradually increases in depth from about the center toward its extremities, at which points it is deepened laterally to form recesses Gr G, as best illustrated in Fig. l. Secured to the stiles E E of the sash, within the grooves F F, are semi-elliptic springs H, each of the latter having its extremities bifurcated to form bearings for a roller, I, the one shown being convex upon its periphery to engage the concave guidestrip C on the adjacent side strip, A, of the window-frame.
When the sash is placed in position, the springs H are contracted, and by their eXpansive force keep the rollers I snug against the guide-strips C, to compensate for loose play and thereby prevent rattling. At the same time said sash can be more readily raised and lowered than is ordinarily the case, as owing to the action of the rollers against the side strips there is no tendency to bind. When the sash is raised, the frictional contact of the rollers and guide-strips will ordinarily hold said'sash in the position to which it has been adjusted; but we prefer to provide one of the guidestrips C with a series of .indentations or perforations, J, at suitable intervals apart to engage a rod, K, arranged to slide in the bottom rail, L, and that stile of the sash that is adjacent to said indented or perforated guide- 6o strip.
The rod K is pivotally connected to a springlever, M, by means of a screw, N, said lever being in turn pivoted to a casing, O, that is mortised in the bottom rail, L, ot the sash. The spring-lever M is preferably in one piece with a thumb-piece, I), that has its shank engaged by a segmental slot, Q, in the detachable faceplate R of the casing O, said face-plate being also provided with a thumbpiece, S, by which 7o the sash may be raised.
To place the face-plate R of the casing O in position, it is so held that the free end of the thumb-piece P will pass through the segmental slot Q, in said plate, and the latter is then given a quarter-turn to bring it into the position shown in Figs. l and 7. The under side of the face-plate is provided with a lug, T, that serves to prevent displacement of the pivotscrew N. 8c
To raise or lower the sash the thumb-piece P is pressed downward to disengage the rod K from theindented or perforated guide-strip, and said sash is then actuated by the grip of the operator on the thumb-piece S, belonging to the face-plate of casing O, both thumbpieces being grasped at the same time with one hand. The construction by which we accomplish the operation just described is a decided advantage over the ordinary style of 9o window, wherein the lock has to be worked by one hand while the sash is raised or lowered by the other.
If found desirable, the opposing faces of the guidestrips C and rollers I may be dat, or in some instances we may omit said strips; and while we have more particularly described our invention in connection with a verticallyy operating sash, it may be as readily employed on the sashes that work horizontally. roo
Our invention is very simple in its construe tion and can be readily applied to any window ata comparatively small cost.
Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is-
l. In a window, the combination, with the frame and sash, of a sliding rod arranged in the sash to engage the frame, a spring-lever pivotally connected to the rod and provided withathumb-pieee, and a face-plate, also provided with a thumb-piece and having a Curved slot to engage the thumhpieee on said lever, substantially as set forth.
2. In a window, the combination, with the frame and sash, of a easing mortised in the sash, a spring-lever pivoted in the casing and provided with a thumb-piece, a sliding rod pivotally connected to the lever and arranged in said sash to engage the i`rame,and a face-plate for the easing, also provided with a thumbpiece and having a curved slot to engage the thumb-piece on the lever, substantially as set forth. Y
3. In a Window, the combination, with the frame and sash, of guide-strips arranged on the frame and one of these guide-strips provided with indentations or perforations, semipiece on said lever, substantially as set forth.-
In testimony that We claim the foregoing We have hereunto sot our hands, at Milwaukee, in the county ol Milwaukee and State of Wisconsin, in the presence of tWO Witnesses.'-
