'CHARLES E. STOSE, OF KANSAS CITY, MISSOURL ASSIGNOR OF FORTY ONE-HUNDREDTHS WINDOW CONSTRUCTION.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed. February 2, 1907. Serial No. 355,495.

To all whomjt may concern:

Be it known that I, CHARLES E. STosE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Window Construction, of which the following is a specification. This invention relates to windows and more especially to railway coach windows, and my object is to produce a window which will be perfectly air tight and in which the sash can be easily and quickly raised or lowered.

A further object is to produce means for locking the window against any attempt to raise it prior to the withdrawal of one of the jambs from the opposing edge of the sash.

With these objects in view and others as hereinafter, appear the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1, is a horizontal section of a window embodying my invention. Fig. 2, is a vertical section on the line IIII of Fig. 1. Fig. 3, is a horizontal section on the line IIIIII of Fig. 2. Fig. 4, is a perspective view on a reduced scale of the casing for the movable jamb forming a part of the invention. Fig. 5, is a view similar to Fig. 1 of a modified form of construction. Fig. 6, is a view taken on the dotted line VI of Fig. 5 but on a smaller scale. Fig. 7, is a view taken on the line VIIVII of Fig. 5. Fig. 8, is a vertical section on the same scale as Fig. 5, and on the line VI thereof.

In the said drawings where like reference numerals indicate the same parts in all the figures, 1 indicates a window frame, 2 the uprights, ordinarily called the jambs, 3 the inner stops, 4 the outer stops, and 5 the sash, the vertical corners of the latter being cut away to provide the converging edges 6 to fit snugly against the corres ondingly inclined inner walls of metallic ribs 7 between the stops, said ribs being preferably united by central portions 8. For convenience of attachment the ribs 7 at one side of the sash are provided with flanges 9 fitting between the uprights 2 and the stops 3 and 4 and secured to the uprights by wood screws 10 or equivalent devices, the ribs 7 forming a jamb of eculiar shape and bearing a wedge-like reation to the sash. The ribs 7 at the op osite side of the sash have their outer wa ls of greater width by preference than the corresponding walls of the amb at the firstnamed side, and said walls fit slidingly against the inner surface of a metallic casing 11 fitting in a recess 12 in the juXta osed upright 2, said casing having lateral y projecting flanges 13, which project from its front edges and are held between said upright 2 and the stops 3 and 4. The casing is also preferably provided with end walls 14 as a convenient support for eye-bolts or hooks 15.

At a suitable point the side walls of the casing areprovided with circular holes 16 to form bearings for the horizontal shaft 17 extending inwardly through the upright 2, and terminating by preference in a squared end as at 18, engaged by a corresponding socket in the stem 19 journaled in the casing and having its outer end reduced and journaled in a bearing 20 secured to the casing and secured upon the inner end of said reduced portion of the stem is a handle 21 by which the stem 19 and shaft 17 can be turned when desired.

22 indicates a disk secured rigidly on shaft 17 centrally of the casing in any suitable manner and pivotally connected to said disk at diametrically opposite points and extending in opposite directions therefrom are links 23, the remote ends of the links being pivotally connected to reciprocatory bars 24 provided with cam or inclined portions 25 drawn longitudinally apart by springs 26 connecting the ends of said bars with the eyes of the hooks 15 of the casing. To insure direct reciprocatory movement of bars 24 between the bifurcated brackets 27 and 28, their outer and inner edges are engaged by anti-friction rollers 29 carried by the brackets for the purpose of reducing frictional resistance to the movement of bars 24 to the minimum.

As will be seen by reference to the drawing Sheet 1, the springs tend to pull the lower rod downward and the upper rod upward and consequently rotate the shaft in the direction indicated by the arrow Fig. 2. ize this power of the springs to secure the To util-- sash in the casing with an air tight relation or to clamp it reliably at any desired height, themetallic portion 8 of the movable j amb fitting in the casing is provided with a pair of brackets 30 equipped with rollers 31 engaging the outer and inner edges of the cam portions of bars 24. By this arrangement it will be seen that as the cam portion of the upper bar moves upward and the corresponding portion of the lower bar moves down- Ward simultaneously, they force the jamb equipped with said anti-friction rollers 31 against the edge of the window sash, the strength of the springs being sufficient to hold the sash reliably at any point of adjustment and it Wilbbe noticed by reference to Figs. 1 and 3 that under such pressure the inclined portions of the ribs 7 establish an air tight joint with the correspondingly beveled edges of the sash it being noted that the portion 8 of the jamb does not engage the sash 2, and therefore does not prevent the ribs from being pressed heavier against such beveled edges.

When it is desired to adjust the sash the operator grasps handle 21 and turns it up and toward the left, this action through the medium of links 23 pulling bars 24 endwise toward shaft 17 through the medium of the cam portions 25 drawing the movable j amb away from the edge of the window so that the latter may be permitted to descend. When the handle is released the springs 26 retract and pull the bars 24 away so that their cam portions shall again cause the movable jamb to press against the adjacent edge of the sash and not only establish an air tight joint with said edge but also between the edges at the opposite side of the sash and the stationary jamb. When the handle is turned as explained it is obvious that there is practically nothing more than the weight of the sash for the operator to.lift and that the same can be raised readily with one hand and in fact on the ordinary cars the sashes are of such size that a child can readily raise them when thus released.

I contemplate equipping the stop 4 with a rubber or equivalent strip 32 to provide an air tight joint between the casing 11 and the movable amb as shown in Fig. 1. To prevent a person from raising the sash without first turning the handle 21 properly, I provide means for locking the sash in its closed position, the same comprising a V-shaped arm 33 pivoted to the lower bar 24 and ada ted to project through an opening 35 in the movable jamb intoa recess 36 in the edge of the sash. The opposite end of the pivoted arm is weighted as at 37 for the purpose of holding the sharp end pressed against the portion 8 of the movable jamb, it being understood that the distance between the pivot and the point of the tooth 33, is considerably in excess of the distance between said pivot and the portion 8 of the jamb. As a result of this construction an attempt to raise the sash must fail unless the lower bar 24 is first moved upward so as to raise the pivoted catch arm and at the same time pivotally operate it in the direction indicated by the arrow under the pressure upon' portions to force the movable jamb further away from the bars 24, the action of the arm described is reversed and it stands with its pointed end against or below the edge. of the sash according to the position of the window and ready to swing into the recess 36 when the sash is again completely lowered. it will thus be seen that this mechanism is automatic and that the withdrawal of the jamb from the sash instantly effects the unlocking of the latter. The construction above de scribed is designed primarily to accommodate window constructions which are in common use at present.

In Sheet 2, I show a construction as follows :38 indicates a cross pin carried by the. movable jamb and 39 a link pivotally secured to said cross pin and extending upwardly through an opening 40 in the adjacent upright 2 and also through a registering opening 41 in a bracket 42 bolted as at 43 to said upright, and provided with alined. bearings 44 for the shaft 45 on which the outer end of the link 39 is pivoted. The shaft between the bearings is eccentrically enlarged as at 46 and in this connection it will be noticed that the bracket is in sections as otherwise it could not be fitted on the shaft at opposite sides of the eccentric and secured to said eccentric at opposite sides of the linkare a pair of stiff springs 47 which bear at their upper ends against the upper portions of the bracket.

At its inner end the shaft is squared as at 48 and said squared end is adapted to be engaged by mechanism corresponding to that shown in Sheet 1 and correspondingly numbered, the )IGSSUIB of the springs 47 against the unyielding bracket 42 results in turning -the shaft in the direction indicated by the arrow Fig. 8 so as to tend to throw the eccentric portions of the shaft forward of its axis and thus cause the movable jamb to clamp against the sash as hereinbefore explained in connection with the first sheet of drawin In view of the height of the window it is necessary to provide pressure at two or more points and for this purpose I interpose springs 49 between the movable jamb and the upright 2, the s)rings being secured at one end to the amb )y preference. By thus applying spring pressure above and below the center of the jamb the latter is main- '1 tained in its proper relation to the sash and will have but little tendency to tilt as it would under the application of pressure at only a single point nearer one end than the other. By manipulating handle 2]. so as to turn the shaft in the opposite direction to that indicated by the arrow Fig. 8, the pressure of the springs is overcome and the amb is pulled away from the window so as to permlt the latter to be adjusted in the manner explained.

The construction shown by Sheet 2 is intended primarily for use u on cars which have no vertical rods behin the uprights 2, and for cars equipped with such rods the construction shown on Sheet 1 is preferable, though it will also be apparent that the lastnamed construction is adapted for use upon cars equipped with windows of any type.

From the above description it will be apparent that I have produced a window construction possessing the features of advantage enumerated and I wish it to be understood that I do not desire to be restricted to the exact details of construction shown and described as obvious modifications will suggest themselves to one skilled in the art.

Having thus described the invention what I claim as new and desire to secure by Letters Patent, is
