JOHN W. GRIFFITHS, OF EAST BOSTON, MASSACHUSETTS.

Letters Patent No. 114,675, 'dated May 9, 1871.

IMPROVEMENT IN RAILROAD CARS.

. The Schedule referred to ln these Letters Patent and making part of the same.

I, JOHN W. GRmrITHs, of EastBostoin-in the county of Suffolk and State of .Massachusetts, have invented certain Improvements in the VConstruction of Railroad Cars, of which the following is the specification.

In the drawing- Figure 1 is an end view or elevation;

Figure 2 is a side elevation; y

Figure 3 is a plan view of the top; and

Figure 4 is av plan view of the bottom, looking 4down from the inside of the body of the car.

rlhe invention consists in the construction of the bodies of'railroad cars, in which the ribs are of wood, bent toform the sides,-top, and bottom of the body.

A A are the ribs, made of wood, bent to forni 4the body of the, car, as represented in iig. 1, having the ends abut together at a and form the cross-sills of the bottom of the car-body.

. B B are transverse sills, for thedouble purpose of securely holding the ends of the bent ribs in place, and, with the ribs, sustaining the floor of the car, and

`are bolted horizontally to the ribs, as seen in figs. 2

and 4. y

G C are longitudinal rails, which form the base for the windows. They are made in two pieces, eaeh half having a notch on its edge to receive the rib, and when put on the ribs will meet at their edges. lhey are then bolted to and through the ribs, as seen in figs. 1 and 2.

D D are longitudinal rails above the windows, and

are attached to the ribs in the saine way as the rails IC; butin being notched onto the ribs the two parts do' not cometogether, but leave a space between them for the window-sash to slide freely up through such opening.

E E are longitudinal rails placed above the rails D to form the base ofthe Ventilating-opening.

E F are straight or upwardly-curved transverse caps, to form the upper margin ofthe Ventilating-orices and make the ibundation for-the roof` ofthe car. .Lhey are bolted in a horizontal direction ou the side ci' ribs A, and thus form a strong base for receiving and supporting the roof ofthe car.

Gr Gr are longitudiualslls of the length of the body ofthe car, and to which the bent ribs A are bolted.

rI he ribs A are made from wood, of the length to make the circumference ot' the center of the wall of the body of the car, well steamed, and bent in the form that the car-body in cross-section is to have, and are secured to the'longitudinal sills Gr and to transverse sills B by bolts.

The ribs A can be made of two pieces, in which case they will have joints at a and a; but when made of one piece are preferable, and in that case the joint will be at a.

For the sills of lthe end platforms a piece of wood, of the proper vsize andlength, is bent in the proper form, and secured to longitudinal'sills G in any'secure way.v l

The frame of acar-body thus constructed is stron ger, less liable. to break intospliuters in ease of a collision, is lighter and more elastic, which gives to it greater ability, and at the same time decreases its cost of co nstruction.

The car-body thus constructed can also be covered on the outside in any way desired, either with wood, metal, or other substances, as the frame being wholly of wood the outside covering or inside tinish can be readily applied.

Having thusl described 'my invention,

What l claim, and desire to secure by Lett-ers Patent, is

'1. The ribs A, made from one'piece or' Wood, the ends abutting at a, bent in the form and secured in the manner described.

2'. The frame of a railroad ear, when constructed fromthe` wooden 'bent ribs A, transverse sills B, rails C, D, and E,`caps Fhand sills G, the'several parts formed, arranged, and secured together in the manner described.

JOHN V. GRIFFITHS.
