CAR-WINDOW.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed May 24,1906. Serial No. 318.458.

To all whom it may concern:

Be it known that I, EZRA S. BUOKNAM, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Car-IN' indows, of which the following is a specification.

The object of my invention is to provide a car window which will be closed by two sashes, one resting immediately below the other, and to provide means for causing the lower sash to be moved laterally from under the upper sash, then to be engaged thereby when raised abreast thereof. When the windows are closed the reverse operation takes place. This object is accomplished by means of my invention, one embodiment of which is hereinafter described.

For a more particular description reference is to be had to the accompanying drawings forming a part hereof, in which,

Figure 1 is a perspective view of that portion of a car provided with my improvement, a portion of two sashes being shown therein.

Fig. 2 is a sectional view showing the sashes when the lower one is moved from under the upper and is partially abreast thereof. 3 is a sectional view of a portion of a car showing the sashes in their closed position. Fig. 4 is a sectional view of the structure below what is shown in Fig. 3. Fig. 5 is an end elevation showing portions of the structures shown in Figs. 3 & 4. Fig. 6 is an enlarged sectional view showing the lower sash forced from under the upper. Fig. 7 is a front elevation of the view shown in Fig. 6. Fig. 8 shows the same structure as Fig. 7, except that the parts are broken away to show the shifting mechanism, the outside of the window being shown. Figs. 9, 10, 11 & 12 show various details of this shifting mechanism.

Throughout the various views of the drawing, similar reference characters designate similar parts.

IVhile my invention may be applied to any window. it is particularly adapted to car windows used in what are known as semi-convertible cars.

In the embodiment hereinafter described, the car is provided with the usual posts or stanchions 1, which support the roof 2, which is preferably a decked roof, and the head-lining 3, all of which may be of the conventional form. A guiding strap 4 is fastened. at its Fig.-

lower end to a sign-plank 5 immediately below the roof, and at its upper end to the vertical support of the decked part of the roof. As many of these straps 4 are employed as desired, but preferably two for each window. The upper sash is suspended from this strap 1 by means of a standard 6 which is secured to this upper sash 7 by any suitable means, as by screws 8. The standard 6 has a projecpion 6 adapted to be engaged by the lower sas 1.

The side edges of the sash 7 are provided with flanges 8 having an inturned edge 9 which runs nearly, but not quite, parallel covers the point between the upper sash 7 v and the lower sash 13.

The lower sash 13, when the window is closed, rests immediately under the upper sash '7 as shown in Fig. 3. This sash 13 is preferably, but not necessarily, provided with an angle metal re-inforce 14 on its upper edge which is similar to the re-inforce 11 and its side edges are provided with similar metal re-inforces 15 which are so shaped as to have a groove 16 adapted to receive the edge 9 of the flange 8, and this metal re-inforce 15 is sufliciently large so as not to be filled by the glass holding portion of the sash, but to leave a space for a purpose which will appear below.

The upper inner and outer faces of the sashes 13 are provided with U shaped recesses 16 near each corner, which recesses receive the outer lugs of a slide 17. This slide 17 is provided with a diagonally ex tending face 18 and a laterally extending lug 19. Two small lugs 20 extend into the recesses 16" and guide the slide 17 during its movement, or hold it when at rest.

The lug 19 is preferably perforated with a screw threaded perforation to receive a small shaft or bar 21 which runs vertically to near sash 7, as indicated in the drawings.

nected to the link 22 which is in turn pivotally connected with the end of the lever 23 which is the hand lever for operating the bolt of the sash' This bolt is controlled by a small lever 24, the upper end of which impinges against a projection 25 on the lever 23, and the lower end against a projection 26 on the bolt 27 which slides in guides 28 fixed in the lower edge of the sash and integral with a plate 29 which is secured to the sash in the usual manner.

A coiled spring 30 tends to force the bolt outwardly, and the action of the lever 23 is such that the bolt 27 is Withdrawn against the tension of this spring 30 and at the same time the rod 21 is raised vertically so that the slide 17 is raised. The hand hold 31 is made integral with the plate 29 and is conveniently located immediately below the lever 23.

The post 1 is provided with the usual weather strip 32 which is continuous from the window sill to the top of the window, and against which both the upper and the lower sashes rest. This strip 32 forms the outer Wall of the slideway for the sashes 13 & 7, and the inner wall is formed by the usual parting strip 33 which flares inwardly to enable the lower sash 13 to get from undegl thlie s parting-strip 33 is provided with a leaf spring 34 which normally tends to force the upper end of the sash 13 immediately under the sash 7, and when this sash moves from under the upper sash it is against the tension of this spring 347 7 From the foregoing the operation of my improved window will be readily understood. Assuming the parts to be in the position indicated in Figs. 3 & 4 the windows are opened as follows: The lever 23 is depressed, thereby withdrawing the bolt 27 and elevating the slide 17. The elevation of the slide 17 forces the upper end of the sash 13 inwardly against the action of the spring 34 until the edge 9 of the flange 8 is immediately over the groove 16 in the re-inforce or stile 15. The lower sash is then raised until its upper edge strikes the standard. 6, when, if the movement be continued, both upper and lower sashes move together as a unit, the movement being guided by the strap 4 and this is continued until the sashes rest in the position indicated by dotted lines in Fig. 3, when the lever 23 isreleased and the bolt 27 enters a suitable hole 35. Should the window be less than fully opened it may be held by a suitable bolt receiving recess 36 located at any convenient point or points below the socket 35. When the sashes are lowered the reverse operation is carried out the sashes move as a unit until the upper sash 7 is in place, when the lower sash moves on guided by the flanges 8. with their edges 9 until the sash 13 is entirely below the sash 7. At this time, when the bolt is released, the slide 17 is immediately lowered and then the spring 34 forces the lower sash immediately under the upper sash. where it impinges against the weather strip 12.

While I have shown one embodiment of my invention, it is obvious that many others.

may be made, so that I do not regard it as limited to the precise disclosure herein made, but as broad enough to cover all structures that come within the scope of the annexed claims.
