CAR.

Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed August 12, 190B. Serial No. 448,086.

To all whom it muy concern:

Be it known that I, EZRA S. BUCKNAM, a citizen of the United States, and a resident of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Cars, of which the following 1s a specification.

The ob'ect of my invention is to provide a car wit i suitable windows, each of which is provided with an upper and a lower sash so arranged and connected that the raising of the lower sash will also raise the upper sash and the two will move together into and out of the roof pockets and also to provide the upper sash with suitable means for permitting it to be lowered so that it will have a cert-ain amount of movement while the lower sash is at rest in its lowest position, so that the window may be opened at the top, a desirable feature in interurban trallic where high speeds are utilized.

This object is accomplished by my invention, one of the embodiments of which is described below.

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

Figure 1 is a sectional view showing a window provided with my improvelnent. Figs. 2 and 3 are sectional views taken on the lines 2 2 and 3 3 respectively, of Fig. 1. Fig. 4 is an enlarged view of a portion of the structure shown near the line 2 2 of Fig. 1. Fig. 5 is a detailed view showinga portion of the lower sash. Fig. 6 is a sectional view showing a portion of the bottom of the lower sash and the parts adjacent thereto. Fig. 7 shows the pintle in the position it occupies when the Sashes are raised into the roo-f pocket. F ig. 8 is an enlarged detailed view showing the structure near the line 3 3 of Fig. 1.

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

My improved car window 1 is rovided with stanchions 2 connected by tlie usual window sills 3 and letter board 4, roof 5,

deck rail 6, head lining 7 curtain molding 8 as well as the other parts not shown, all o which are of the conventional type, except as hereinafter noted. The stanc ions 2 are also provided with the outside parting strip 9 and the inner parting strip 10, as well as the strip 11 which dehnes one wall of the curtain groove 12. The Stanchions 2 also have a pintle way 13 that extends from the deck rall G to or near the Window sill 3 and preferably extends substantially as shown in Fig. 1. This pintle way has holes 14 adapted to receive the bolt 15 which is secured near the lower edge of the lower sash 16 in the conventional manner. Below the line 3 3 in Fig. 1 this pintle groove 13 curves outwardly and downwardly until in the plane of the sash 16, when it follows the plane of this sash so that the bolt 1.5 will always rest therein or in the holes 14. This bolt 15 can be withdrawn from the holes 14 in the bottom of the groove 13 but not from the groove 13 while the sash 16 is in use so that the sash may be held in any desired position.

The outer edge of the sash 16 is provided with a stop 17 above which is a metal slideway 18 secured to the outer edge of the sash 16 and in this slideway 13 is mounted the upper sash 19 which is so arranged and disposed that it can slide freely in the slideway 18 until its movement therein is limited by the stop 17. Near its upper edge, the sash 16 is provided with a pintle 20 which may be of any suitable form but is preferably made as follows. It is provided with a base 21 .secured to the inside of the sash 16 by screws or other suitable means, and it is provided with a trunnion 22 on Which is pivotally mounted a slide 23 which has a large wearing face that rubs against the inner wall of the groove 13 so that this pintle will move over said groove with the least possible friction and wear and tear, The exte rior of the sash 16 and immediately below and secured to the top bar 24 thereof is a stop 25 which engages a second stop 26 secured to the upper sash 19 substantially as shown in Fig. 8. The stops 26 and 25 engage to limit the upward movement of the sash 19 while the sash 16 remains at rest and also to cause the lower sash to force the upper sash into its proper position when the window is closed.

The u per edge of the uplper sash'19 1s provide with a suitable bo t 27 which 1s adapted to enter holes 28 as shown 1n dotted lines in Fig. il. When the upper sash is so lowered, it slides as stated above in the slidewa f 18.

lirom the foregoing the oieration of my improved device will be reaily understood. By withdrawing the bolt 15 from its hole 14 and raising the lower sash from the position shown in Fig. 1 in the full lines to the position shown 1n the dotted lines this sash is raised vertically and the slides 18 enga Ic the sash 19. llVhen the two sashes are a reast they are raised together. When lowered they are also together until the sash 19 is in place when the sash 1G continues its move* ment alone and the stops 26 and 25 cause the sash 19 to take its proper position when the lower sash 16 is in its proper position and the slide 23 forces the two sashes to ether so that they are held with a substantial y watertight joint. By withdrawin the bolt 2T, the sash 19 may be lowered rom the position shown in Fig. 1.

While I have shown one embodiment of my invention it is obvious that it is not restricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claims. l

What I claim is:

1. In a device of the class described, a pair of stanchions, each of which is provided with a pintle-way, upper and lower sashes adapted to slide between said stanehions, means permitting the upper sash to be lowered while the lower sash is being raised, means for causing the lower sash to either raise or lower the upper sash so that both may be moved together upwardly or downwardly, and pivotally mounted means for automatically causing the upper sash to assume its proper position when the lower sash is down.

2. In a device of the class described, a pair of stanchions each of which is provided with a pintle-way, upper and lower sashes adapted to slide between said stanchions, means for permitting the upper sash to be lowered while the lower sash is being raised, means for causing the lower sash to either raise or lower the u per sash so that both may be moved togetlier upwardly or downwardly, means for allowing the lower sash to continue its movement alone after the upper sash is closed, and pivotally mounted means for automatically forcing the sashes together when the lower sash is closed.

3. In a device of the class described, a pair of stanohions each of which is pro vided with a intle-way, upper and lower sashes adapte to slide between said stanchions, means for A)ermitting the upper sash to be lowered while the lower sash 1s being raised, means for causing the lower sash to either raise or lower the upper sash so that both may be moved together upwardly or downwardly, means for allowing the lower sash to continue its movement alone after the upper sash is closed, and a pivotally mounted slide on the lower sash for forcing the sashes together when both areclosed.

4. In a car of the class described, a win dow having stanchions at either side, an upper and a lower sash adapted to slide be tween said stanchions, the lower sash being provided with a stop and a slideway, the upper sash being mounted in said slideway and engageable with said stop, means whereby the upper and lower sash are moved downward together until the upper sash is in closed position and allowing the lower sash to continue its movement alone and rocking means carried by the lower sash for auto matically forcing the sashes together when the lower sash reaches its closed position.

5. In a. car of the class described, a window having stanchions at either side, an upper and a lower sash adapted to slide between said stanehions, the lower sash be ing provided with a stop and a slideway, the upper sash being mounted in said slide way and engageable with said stop, means whereby the upper and lower sash are moved downward to other until the upper sash is in closed position and allowing the lower sash to continue its movement alone, and pivotally mounted means on the lower sash for forcing the sashes together when the lower sash reaches its closed position.

Signed at the city and county of Philadelphia, State of Pennsylvania, this 10th day of August, 1908.
