V6 claims. (C1. 20A-69?) This inventionrelates to a closure and frame construction and has for an object therprovision of improvements in this art.

One of the particular objects of the invention is to provide a closure and frame construction f which furnishes a dependable weather seal against the entry of air or water (rain, snow, or the like) and against the freezing of ice around the closure joints where it might interfere with the opening of the closure.

Another object is to provide a Dutch type closure construction which is divided transversely and which provides a good weather seal of the non-freezing type at the dividing joint.

Another object is to provide a simple but strong closure and frame construction which furnishes the desired weather seal. y

Another object is to provide a closure and frame with means for holding the parts tightly together but which does not obstruct the free drainage of water, which furnishes the minimum obstruction to traffic passage through the closure opening, and the least complication of related wall constructions.

The construction has been developed and is especially suitable for use in connection with outside vestibledocrs of railway cars, and will be described in this setting but without limitation upon its many other manifest uses. p ln the accompanying drawings of this illustrative embodiment:

Figure 1 is an outer side elevation of one end of a railway car having a vestibule door or closure embodying the invention;

Figure 2 is an enlarged inside elevation of the door and frame, the door on the opposite side from that of Fig. 1 being shown;

Figure 3 is an enlarged vertical section through the top of the door and frame, the view being taken on the line 3-3 of Figure 2;

' Figure 4 is an enlarged vertical section through the transverse joint between the upper and lower parts of the door, the view being taken on the line 4-4 of Figure 2; l

Figure 5 is an enlarged vertical section through the bottom of the door and frame, the View being taken on the line 5--5 of FigureZ;

Figure 6 is an enlarged horizontal section through the front, outer or fastener side of the door and frame, the view being taken on the line 6--6 of Figure 2;

Figure 7 is an enlarged horizontal section through the rear, inner or hinge side of the door and frame, the view being taken on the line 'l--l of Figure 2;

Figure 8 is a slightly enlarged verticalsection taken on the line 8 8 of Figure 6, showing a door latch in closed position; and

Figure 9 is a vertical broken partial section of a slightly modified construction.

In l'Figure l a railway car I0 with sidewalls i I is shown to be provided with an outer vestibule door frame i2 which is closed by a two-part Dutch door I3 including an upper part or section I3a and a lower part or section |319. For convenience the elements of the frame are designated as the top IEa, the outer or latch side |2b, the inner or hinge side I2C, and the bottom or threshold I2d, which is a part of a foldable trap door or of a step assembly I4 which is folded up when the door is closed.

As shown in Figure 2, each part or half of the door is mounted on hinges I'l, preferably of the piano type illustrated, and each half is held closed by a latch I8 which is mounted on the frame. The latch cooperates with a keeper camstop element I9, shown best in Figures 6 and 8, to force the door parts into closed position. The bottom stop ledge lila prevents the latch from dropping down oit the keeper and thus prevents the door from opening inadvertently. When the door is open the inside handle Ilia may be placed over against the outer end wall 2U of the vestibule, as shown in dotted lines in Figure 2, but if it drops down it will stand clear of the door in closing, to prevent injury. t may be raised by reopening the door until the handle is cleared. Another handle I8b may be provided on the outside of the car.

Whenunlatched, the upper part of the door may be grasped by a pull 22 provided thereon. The lower door, which is opened last, may be moved by grasping its upper edge. By placing the latch on the frame and by providing a thin pull plate which overlies the panel space behind it, the door is left without any substantial inside projections, and it is not necessary to provide projection-receiving recesses in the inner end vestibule wall 23 as has been common heretofore. Latches 24 maybe provided at or on the wall 23 to hold the door parts open.

, Around all outer edges of the door and between the parts of the door the structure is so formed as to provide relatively large interior channels 25 which are almost closed on the outside to minimize the entry of air or water but whoseouter edges are still sufiiciently spaced apart to prevent freezing together under most conditions. The sheltered channels are fully closed on the inner side by weatherstripping 26. The weatherstripping is so placed as to avoid the formation of a dam for water which might freeze to hold the parts together. The sheltered channel prevents all but a small amount of water from entering from the outside, even in a hard side-driving wind, and the channels all interconnect and open at the bottom so as to rapidly drain away such water as does enter. Moreover, the weatherstripping is all located at the inner side of the drainage channel where the heat from inside the car can reach it and prevent freezing of such small amounts of water as may get in. At vthe outside the channel is dened by sharp edges which prevent inward creep of water and cause it to drip off. If ice should form here, it will be in a thin sheet extending from a narrow edge presented toward the adjacent part, hence easily broken; and if such a thin sheet does form over the outside. it will seal the channel against the entry of practically all water.

The upper door part or section |3a (Figures 3, 4, v6 and 7) is formed of a main panel 30 to which near each edge there Yis secured the flange of an angle member 3| which at its outer edge is spaced from the main panel 30 and connected therewith at the top and bottom by an inwardly -bottomed U-shaped peripheral member 32. At the front and back edges the vmain panel 30 is bent laterally and then back into a parallel plane, and its outer flange thus formed i-s secured to the border angle member 3|. At the front edge, Figure 6, the border member 3| is turned over and vback on the outer flange of the main panel to form a thin stiff edge. At the rear, Figure 7, besides the leaf of hinge there is secured an angle-section strip 33, all secured together, for example, by bolts. An inner panel 34, as of glass, is secured to the inner ledges of the main panel 30, as by a well-known type of vrubber strip molding 35. At the top the U-section strip 32 has its outer leg shorter than its inner leg so as to pass the weatherstrip 26a which is secured to `the top of the frame and allowing the inner leg to engage the weatherstrip.

The lower door part or section |3b (Figures 4 and 5) is formed of a main panel '40 to which neareach edge there is secured the flange of an angle-section member 4| which at its outer edge is spaced from the main panel 40 and is connected therewith at the top and .bottom by a U-shaped peripheral member 42. At the front and back edges the construction is like Athat described for the upper door part. A stiiening strip 4B is secured across the main panel -4'0 and cover` trim plates 41 are secured over all the Araw inside edges, these trim plates also serving to stiffen and strengthen the lower door part.

The weatherstrip 26a fat the top l(Figure '3) is tubular and secured to the `top |-2a of the frame. An .inwardly extending projection lor edge '48 of the lframe stands close to the outer surface of the door when itis closed and with the door forms the restricted entrance into the vchannel 25 at the top.

At the rear (Figure '7) the weatherstrip 25e is tubular and secured to the .rear or inner part |2c of the frame. One flange of Ithe angle vmember v33 engages the weatherstrip when the door is closed. An inwardly extending projection or edge 49 of the frame stands close to the outer surface of the door when it is closed and with the door forms the restricted entrance into the channel 25 at the rear or hinge-edge of the door.

At the front (Figure 6) the weatherstrip '26h is tubularand secured to the front or outer part |211 of the frame. An inwardly extending projection or edge 50 of the frame stands close to the outer surface of the door when it is closed and with the door forms the restricted entrance into the channel 25 at the front or latch edge of the door.

At the bottom (Figure 5) the weatherstrip 26d is iat and secured to the :inside bottom surface of the door. It engages a vertical portion of the threshold. The threshold slopes downwardly toward the outside to drain. Here the lower outer edge of the door stands near the top of the threshold to form the restricted opening into the -channel 25 when the Vdoor is closed.

At .the middle (Figure 4) the weatherstrip 26e is `flat and secured to the inside bottom surface of the upper door part and engages the top inside surface of the lower door part. The lower outer edge of the upper door part and the upper outer edge of the lower door part stand close together when the door parts are closed to define the restricted opening into the channel 25. In a double door of this type it is considered that one part forms va part lof the frame of the other part.

In the modified form shown in Figure 9 the upper door part |3a at its bottom edge is provided with a sharp-edged .projection 3|a which extends outwardly and Adownwardly 'within l"the channel 25 to cause any Water which is flowing downward to drip off .into the channel and ldrain olf. This protects against creep of water to the weatherstrip 256'., which is -made bulbous in this form. At the bottom of the lower door, part |3b" is likewise .provided with a drip projection 4|a' which protects the weatherstrip 26d' against creeping water. The drip projections preferably extend at their ends -to the verticalweatherstripping. There is thus provided at the lower edges, where water creep is most troublesome, both outer and inner drip edges, which, with the 'cooperating structure, give great assurance of excluding al1 water.

It is thus seen that there is provi-ded 'a vsimple and strong door and frame construction; that it minimizes the passage of weather into the protected channels; that lit effectively Vdrains water entering these channels; that it seals the channels on the inside; and that it provides secure and convenient means for holding the .door against its sealing strips.

While one Aembodiment of the invention 'has been illustrated and described, it will be apparent that there may be various embodiments within the broad concept of the invention.
