14 Claims.

This invention relates generally to railway cars and has particular reference to a new and improved body construction therefor.

'I'he trend of car building at the present day is toward the provision of railway cars which are Another object of this invention is the provision of a railway passenger carin which projec-I tions from, or recesses in, the sides thereof are reduced to a minimum whereby to provide for streamlining.

Still another object of this invention is the provision of a railway car in which the'outer surface thereof is substantially smooth and uninterrupted from end to end ofthe car to reduce wind resistance to a minimum.

A A further object of this invention is the provision of Aa new and improved body frame construction i'or railway passenger cars.

This invention also contemplates the provision of new and improved means for mounting the window sashes in a railway passenger car.

Another object of this invention is the provision of new and improved body post construction i'or railway passenger cars.

The above and other objects of this invention will be apparent from the following description taken in conjunction with the accompanying drawings in which:

Fig. 17 is a still further. modication of the construction, the .view being a sectional view similar to Fig. 16 but disclosing the body posts as facing outwardly.

The drawings, as will be evident from .the description of figures just above, disclose several modifications of the present invention dealing mainly with sash Vsecuring means. However, two types of car bodies are illustrated and reference will now be had to the type shown in Figs. 1 to 4 inclusive in which the car is built with side sills A, side posts B, plate C andouter sheathing D. Window openings E are provided between the side posts and between end post F and door pocket G and, since the car is designed primarily for passenger carrying in subways, the window o nings are closed by lower xed sash H and upper 'I'he side sills are of general channel formation having lower flange 2, web 3 and upper flange 4 which is shown as extended to support the floor plates 5. 'I'he side posts are in the instance shown formed of extruded metal to provide inner flanges 6, main webs 1, outwardly extending sash stops 8 substantially in alignment with shoulders 9, from the inner edges of which auxiliary webs I extend to be joined by outer portion Il substantially in the plane of the side sill web. These posts may be considered as formed of either three channels with webs 1 and Il or as formed of an external anged U and two angles having legs 'i joined to the external flanges of the U. The lower ends of the posts are suitably secured to the side sill, while the upper ends are modified to conform to the car contour if necessary and be secured to the plate C by suitable means such as pressed clips I2.

The posts are joined intermediate the plate and sill by. longitudinally extending external flanged U-shaped bracing members --l4 having their external iianges I5 secured to stops 8 and shoulders 9 of the posts, while the flanges I6 abut and are secured to the auxiliary web I0 of the post. These anges are of such depth as to place the web I1 inthe same plane as the post portion l l in order to receive and stiffen the side sheet' and the top part is formed by angle means 2| suitably secured to the posts in the oiset thereof and to the letterboard 22 which underlaps and,

forms a continuation of the special top plate.

Fixed windowl pane H is mounted in rubber channels R and is clamped against the stops 8 by means of iinish strips 24 held in place by bolts or other means 25. The finish strips are provided with shade or curtain guides 26 and any extended metallic contact between the strips and the post is prevented by an insulating strip 21. The post ilnish strips 28 are of channel formation insulated from the post by insulating block 29 and these strips are held in place by suitable means 30 as well as by the bolts 25. The bottom portion of the window sash abuts portion 3| of sealing strip 32 securely fastened to the side sheet and framing by suitable means such as rivets 33 and the sash is clamped in place by nish strip 34 which rests upon lower finish str ip 35 and is held in place by means such as screw bolts 36. The finish strips are insulated from the framing and posts by insulating material 31 and the lower iinish strip is also held in place by screw means 38. The lower sash is thus held securely clamped in position and the customary sash frame is dispensed with,

which materially lessens the weight of the unit for transmission of light.

The upper 'or sliding sash I is of necessity mounted in a frame J -of somewhat usual construction and this frameis adapted to slide in suitable guides 40 iitted in the bend between post portions 9 and l0 to which latter portion they are secured by suitable means 4I. At the upper portion of the window sealing means 42 is provided suitably held in place, but if desirable the guide 40 may be continued across the top edge in which case the top finish strip 43 would be modified. Exterior post finish strip 44 is suitably secured tothe post portion lll as by means of countersunk screw bolts 45 and this strip protects and holds the guide 40 in place. It is obvious that if -sash I for any. reason needs to be removed, it is only necessary to remove the exterior iinish strip and sash guide and that the interior finish need not be disturbed.

In the forms shown in Figs. 5 to 8 inclusive the post design has been changed slightly in order that the post may be formed by dies and advantage thus taken of high tensile steels which do not lend themselves to extrusion. The change in post design necessitates changes in window securing details and several methods of accomplishing the desired result have been shown and will be described in more or less detail. In these figures the post cross sectionis similar to that described in connection with Figs. 1 to 4 inclusive and wherever possible like reference characters have been applied in order to avoid repetition. 'I'his same thing is true of various other elements of the construction and, therefore, emphasis will be placed only on the details wherein the construction varies from that previously described.

In Fig. 5 stop strip 46 is provided having leg 41 secured to the post web by suitable means such as 48 and this strip serves the same function as does stop shoulder 8 of Fig 3. Members 49 are welded to the post portion Il in order to provide .increased area for the threads of the securing screws 45, while the post insulating strip is dispensed with by having the interiorpost finish spaced from the post flanges. The use of the stop strip shown necessitates either the welding of the joint 50 or the extension of the window guide as at 52 to seal this joint.

In Fig. 6 the construction of Fig. 5 is still further lightened by the elimination of the stop strip as a separate element. 'I'he stop for the inner sash is provided by making the guide strip 40 with at least one element 53 of relatively strong material and by extending this element as at 54 to provide the stop shoulder. This arrangement makes an exceedingly light yet strong and simple construction admirably suited to passenger cars or vehicles.

In Fig. 7 the fixed sash is retained in the same manner as in Fig. 5 and like numerals are used to refer to like parts. In this modification the sealing strip 44 is eliminated as such but itsl purpose is accomplished by a lighter member 55 overlapped and secured as by spot welding to angle member 56 which is secured to the post by the same means that holds the sash guide in position. The sash guide is reenforced by channel member 51 which provides the necessary strength for the guide and this guide is extended as at 58 to seal the joint adjacent the stop strip.

The modication shown in Fig. 8 is very similar to that shown in Fig. 6 with the exception that the sealing strip 44 is eliminated and a light strip 60 is bent over and secured to the sash guide `and has its other portion overlapping and sealing the joint between the sash guide and the post.

In Fig. 9 a channel member is provided having an outer ange 62, web 63 and elongated flange 64 which is of such a length as to provide a stop for the inner or xed sash. This channel receives the regular or unmodified guide strip 40 and also carries secured thereto the sealing strip 65 which seals the joint between the channel and the adjacent car structure. In this as in all the other modiiications it is, of course, obvious that the usual car sealing cement'is used around all members that are exposed to the weather and will effectively seal all joints against ingress of moisture due to inequalities of construction.

It is seen from the preceding description that an extremely light construction has been provided by the elimination of all -unnecessary elements and that this has been accomplished without the sacrifice of any strength. In fact the post section as used will for the same weight be considerably stronger both as a beam and as a column than the customary side post. It is also obvious that the projections from the smooth contour of the car have been reduced to a minimum and that the windows have been placed as nearly in the plane of the side as is possible with the sliding type of window. The constructions described will lend themselves admirably to the use of fixed sash wherever it is possible such as in air conditioned cars to use such sash.

.Referring now to the construction shown b Figs. 10 to 12 inclusive wherein a modified car construction is disclosed. The side sill in this case is provided with lower flange 10, web 1| conforming to the car contour, upper ange .12 and reflange 13 which is adapted to overlap and be secured to the fianges 14 of side posts M resting upon and secured to fiange 12.- The posts are similar in design to those previously described in connection with Figs. 5 to 9 inclusive with the exception that the anges 14 are turned outwardly from the web 15 to facilitate attachment of the side sill and lining 16, and also with the exception that the web 11 is curved to conform to the car contour which necessitates the varying depth of portion 18 as clearly shown in Fig. 11. The portions of the post above the window sill 19 are similar in cross section to those in Figs. 5 to 9 inclusive and are subject to thesame modifications in window securing means, while the upper end of the post is secured to the plate 80 in any desired manner. The posts are joined by longitudinals 8| which are continued across the posts by channel shaped members 82 exactly as described in connection with Fig. 2.

The car construction shown in Figs. 13 and 14 discloses the manner in which fixed sash such as is used on air conditioned cars may be applied. 'Ihe side posts are of the same type as previously described and the only necessary changes in the framing consist of the addition of an angle shaped extension 83 to plate 80 and the pressing oi window sill 19 to provide offset portion 84. The sash, which is preferably of the double paned type, is mounted in rubber carried by frame T, which frame is formed with an offset 85 of such depth as to bring the outer surfaceof the frame fiush with the retaining member 86, thus positioning the glass as near in alignment with the car sides as is possible. The frame is mounted in rubber sealing channel 81 and the whole held in place by the member 86 through the use of removable means 88. It is thus seen that the window is held clamped as nearly as possible in the plane of the car side and that it is readily removable without disturbing the interior finish now tc be described.

The side post has secured thereto insulating blocks 89 which are protected by finish strips 90 and 9|. The finish strip 90 is provided at one edge with flat surface 92 abutting the Window frame and is held spaced from the insulating block by flange 93 and channel shaped curtain guide 94.

. 'I'he finish strip is held in place by means 95 and is provided adjacent the curtain guide with flange 96 to which the finish strip 9| is secured by suita- .ble means such as 91.

Themodification shown in Fig. 15 is identical with that shown in Fig. 14 with the exception that an unmodified sash frame has been used which causes the window to be recessed-from the car side a greater degree. Since the construction is so similar to that of Fig. 14 the same reference numerals have been used and the same description will apply.

The modincation shown innig. 16 discloses the manner in which the present type of side post and side construction may be rigidified. The side -will, of course,lrequire the type of window construction now used.

In Fig. 17 the 'posts are turned from the'pcsi- 'tion shown in Fig. 1.6 and the refianges I0 are secured to the side sheet I|| which continues the effect of the 'longitudinal inter-post braces I2. The braces are welded to the post reflanges ||0 and flanges H3, while the post web IH being on the inside of the car furnishes a flat surface to which the car lining l5 may be secured.
