UNITED STATES PATENT OFFICE.

FRED MATHEWS, OF CHICAGO, ILLINOIS, ASSIGNOR T0 CLINTON C. MURPHY, OF

CHICAGO, ILLINOIS.

FREIGHT-CAR.

Specification of Letters Batent.

Patented July 4, 1916.

To all whom it may concern Be it known that I, FRED MATHEWS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Freight-Cars, of which the following is a full, clear, and exact description.

My invention relates to freight cars, and particularly to the construction of the sides of the car immediately below the roof and over the door thereof.

It has always been the aim of freight car builders to construct the sides thereof so that the rain cannot beat in, andto protect the metal parts, especially the rivets and bolts as much as possible so that they will not oxidize and work loose in the car. The construction of cars in which the metal framework of the sides is outside the siding makes this diflicult especially above the plane of the doorways.

The object of my invention is, principally,

to safeguard the shed that overhangs the sliding doors of such cars, and to protect the rivets employed to secure the same to the side of the car from rain, and thus prevent their rusting and working loose, and the rain seeping through and damaging the contents thereof. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings: Figure 1 is a side elevation of the central portion of a box car having my improvements applied thereto. Fig,-

2 is a vertical section of a fragment of the same taken on dotted line 22, Fig. 1, and drawn to a much larger scale.

Referring to the drawings, A represents a box-car of the class known as single sheet-- ing box car, the peculiarity of which is that, the metal frame-work is built outside of the siding and only one thickness of siding is used in the construction of the same. This car is provided with a door-way B, the wooden frame-work of which is tightly secured inside of a metallic frame. Above the wooden lintel 0 of this door-frame there is a longitudinally arranged Z-bar G the lower flange of which projects outward and is 86-: cured to said lintel. The upper flange b of this Z-bar projects inward and forms a support extending lengthwise the car upon which the ends of the carlines rest and upon which the wooden spacing or filling blocks D rest and are secured.

The metal carlines E, preferably, consist of T-irons and beyond the portions thereof resting upon the Z-bars the vertical webs of the same are sheared ofl'. These sheared end portions of carlines E extend down outside of said plate in front of the vertical web of Z-bar G a suitable distance and are clamped between the same and the upwardly flanged inner edge (2 of a shed F consisting of sheet metal the horizontal portion of which rests upon the outwardly projecting horizontal flange of Z-bar C and extends out beyond and overhangs the outer edge of the doorway and the longitudinally slidable door G. The outer edge of this shed F is bent downward to form a guard e which not only prevents the rain from beating into the car over the door, but laps over the upper edge of the door F and retains and serves as a guide for the same. i

The upwardly flanged edge cl of shed F and the downwardly extending edge of carline E and the vertical web of the Z-bar C are secured together by rivets f at points slightly above the center of height of the vertical webs of the Z-bar, and theserivets and the lappingsurfaces of the vertical edge 01 of plate F, and the depending edge of the carline E are covered over by a fascia H that is secured to the outer edge of roof planks g and has its lower inner surface is rabbeted or recessed to accommodate the presence of the outer heads of rivets 7 and the metal parts united by the same. As thus constructed, it is physically impossible for the rain to beat up under the lower portion of the fascia and rust the rivets f or the holes through which the barrels of the same pass. I

The construction of the outer frame-work of the car and also the construction of the door is immaterial insofar as the novel features of my invention are concerned, but I prefer to support the door and slide it back and forth upon brackets Khaving anti-friction wheels or rollers upon which the lower imetallically shod edge of the door rests. The upper part of the door is provided with hooks M the shanks of which are secured in any suitable manner to the outer surface of :3; the door. These hooks extend up above the upper edge of the door and lap outside of l-the guard e of shed F, and up over the h0ri zontal portion of the latter a short distance, substantially as shown.

What I claim as new is:

A freight car having a projecting door way, a sliding door for closing the same, a side-wall having a metal plate the vertical web of which extends above the lintel of the door, a roof, carlines supporting said roof and having the ends thereof bent downward in front of the web of said plate, a shed comprising a horizontally disposed metal plate which rests on, top of said lintel and has, the outer edge thereof projecting out over the upper edge of the door and the inner edge thereof flanged upward in front of the end 15 of said carlines and web, rivets uniting said web. and flange, and a fascia secured to the edge of the roof and depending in front of and below said rivets.

In witness whereof I have hereunto set my 20 hand this 30th day of March, 1915.

FRED MATHEWS. Witnesses:
