JOHN H. ROBERTSON, OF NEWT YORK, N. Y.

RAILWAY-CAR.

SPECIFICATION forming part of Letters Patent No. 621,142, dated March 14, 1.899.

Application led November 25, 1898. Serial No. 697,327. (No model.)

To @ZZ 'tz/71,0711, t may concern: l

Be it known that I, JOHN H. ROBERTsoN, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented a new and useful Improvement in Railway-Cars, of which the following is a specilication.

This invention relates to railway-cars of improved construction, whereby either one or both of the lower and upper sashes of each window of the car may be lowered completely below the window-sill, thereby enabling the car to be particularly well adapted for use both as a closed or winter car and an open or summer car.

The object of this invention is to provide an improved construction of the framework at the bottom of the car, which structure will be very simple and strong and which will permit the bottoms of the lower sashes to slide down between the inner and outer framebeams and be there supported, thereby permitting the use of a very low window-sill and correspondingly large windows.

A practical embodiment of my invention is represented in the accompanying drawings, in which-'- Figure l represents a side View of a part of a car embodying my invention in which the end side window is shown closed, both sashes being in their raised position, the next window being shown partially open with the lower sash dropped into its lowered position out of sight beneath the window-sill, and the next window being shown fully open with both sashes dropped to their lowered position out of sight beneath the window-sill. Fig. 2 is an end view of the car. Fig. 3 is a plan view of the car-sill at the end of the car. Fig. L is an enlarged Vertical transverse section through the car, the portion of the car between the sides being broken away and the window being represented as closed at one side and as open on the other side; and Fig. 5 is a detail front view of one of the uprising posts and its adjacent parts.

The sill or framework at the bottom of the car-body, upon which the car-body is supbase of the car and rigidly spaced from the outer beam, and suitable wooden cross-beams extending across the base of the car-body and rigidly secured to the inner and outer beams.

The outer metallic channel-beams are denoted by A and are arranged with their upper and lower flanges d o extended outwardly. These channel-beams extend entirely around the base of the body portion of the car. The end portions of the beams are bent inwardly toward each other at the opposite ends of the car and their ends rigidly secured together by tie-plates o2 and bolts a3, the tie-plate and bolts at one end of the car only being shown in the accompanying drawings.

The inner metallic angle-beams are denoted by B, and they extend along the opposite sides of the base of the car-body, spaced a short distance from the channel-beams A. These angle-beams B have their'flanges h located at thetop of their vertical portions and extended inwardly therefrom, as shown rIhere are two of these angle-beams B, and the vertical portions of their ends are turned laterally and inwardly for a distance toward each other at both ends of the car, one end only being shown in the accompanying drawings. These inwardly-extended portions are `denoted by b. An end cross-beam C extends across the frame between the inwardly-turned ends b of the angle-beam B and the inwardly-'turned end portions of the channel-beams A. A plurality of bolts c extend through the vertical webs of the channel and angle beams and the cross-beam C for securely fastening the parts together.

The side posts which support the roof D of the car and serve as the sides of the windowcasings are denoted by E. These posts rest upon the beams A and B and are secured rigidly thereto by inverted metallic T-bars F in the following manner: The lower end of the post E is bifurcated for a short distance upwardly from its bottom, and the vertical portion of the T-bar F extends upwardly into said bifurcated portion of the post and is there rigidly secured by bolts fi", which pass through the branches of the post and the bar.

The thickness of the T-bars F is equal to the distance which it is'desired to space the beams A and B apart. The laterally-extended arms ff which form the T of the beam F,

are located along the bottom of the space between the two beams A and B. These crossarms serve as stops for the bottom of the lower' window-sashes when the sashes are in their lowered position.

The width of the vertical portion of the T- bar F is such that its edges form continua- Lions of the lower portion e of the sashgroove e, which is adapted to receive one side of the lower sash G of the window.-

The groove e extends from the top of the window down to the sill H, this groove being adapted to receive the sides of both the lower sash G and the upper sash G of the window. From the window-sill II the continuation e' of the groove c is adapted to receive only the lower sash G, while a second continuation e2 extends from the said groove e downwardly for receiving one side of the upper sash G'. The groove ev2 is of sufficient depth to permit the upper sash G/ when in its lowered position to rest entirely below the sill II.

The space between the posts E, from the window-sill II to the tops of the beams A and B, is provided with inner and outer sheathings J and K, as is usual. To close the upper and lower sashes from view when in their lower position, I provide sill-pieces h between the posts, extending from the top of the inner sheathings .I to the top of the sill II. The sashes are thus entirely concealed from View when in their lowered position.

The wooden beams L extend across the frame at the bases of the posts E, and the ends of the beams are secured to the inner sides of the angle-beams B in the following manner: A box-bracket M, preferably of castiron, has its top and inne-r end open for embracing a portion of one end of the crossbeam L, which bracket is firmly secured thereto by bolts m, which pass through the sides of the bracket and the end of the crossbeam.

Bolts N are used for securing the T-bars F between the beams A and B and the bracket M rigidly to the inner side of the angle-beam B. The T-bars thus serve the triple purpose of securing the posts E to the beams A and B, of spacing the beams apart for permitting the reception between them of the lower sash, and as a rest or stop for supporting the lower sash in its lowered position.

Vhat I claim isl. In a railway-car,side posts,window-sashes Iitted to slide between the posts, a bottom frame having outer and inner beams spaced apart along its sides and bars extended upwardly into the side posts and secured thereto and downwardly between the beams and secured thereto for serving the double purpose of securing the posts to the beams and spaein g the beams apart whereby the lower sashes may be received between the beams when the sashes are in their lowered position, substantially as set forth.

2. Inarailwaycar,side posts,window-sashes fitted to slide between the posts, a bottom frame having outer and inner beams spaced apart along its sides and bars for spacing the beams apart and securing the posts to the beams, the said bars being provided with laterally-extended arms at their lower ends along the bottom of the beams arranged to support the lower sashes when in their lowered position, substantially as set forth.

3. Car-frame construction, comprising inner and outer metallic beams spaced apart, cross beams extending between the inner beams, metallic brackets for the ends of the cross-beams, side posts resting upon the outer and inner beams, T-bars extended upwardly into the side posts and downwardly between the outer and inner beams, means for securing the upwardly-extended portions of the bars to the posts and means for securing cach of the cross-beam brackets, the inner beam, the downwardly-extended portion of the T- bar and the outer beam, rigidly together, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 15th day of November, 1898.

JOHN H. ROBERTSON.
