JOHN M. HANSEN, OF PITTSBURG, PENNSYLVANIA.

METALLIC CAR.

SPECIFICATION forming part of Letters Patent No. 761,166, dated May 31,1904. Application ilell January 26, 1903. Serial No. 140,583. (No model.)

To all 1071/0111, 1215 may concern:

Be it known that I, JOHN M. HANsEN,a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Metallic Cars; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to metallic railwaycars, and more especially to the construction of the top of the side and ends of gondola and hopper cars. Y

The object of my invention is to provide a side and end construction for metallic cars of this kind which is adapted to resist transverse forces applied thereto in any direction.

rIhe invention consists in the construction hereinafter described and claimed.

- In the accompanying drawings, Figure 1 is a side view of one-half of the body of a gondola car, showing my invention applied thereto. Fig. 2 is a transverse section through the upper portion of the car side or end. Fig. 8

is a portion of the car side on an enlarged scale, and Fig. 4 is a' plan view of one corner of the car.

The car-body comprises the usual end and side plates l, secured to each other in any suitable way and stiffened at intervals by the vertical stakes 2. These stakes may be of any desired construction, those shown in the drawings being alternately trough-shaped and angle stakes. The side plates and stakes will preferably be so united that together with the usual bottom cord and my improved top they form plate-girders to assist in supporting the load. My invention, however, is not limited in any of these particulars, but applies entirely to the top of the sides and ends of the car-body.

I strengthen the top edges of the side and also of the end plates of the body by means of two flanged bars suitably attached thereto and extending along the top of the plates. These flanged bars maybe of various constructions, but preferably will comprise a Z-bar 5 and an angle-bar 6. The Z-bar is placed with its flanges extending in vertical directions and its web horizontal. rIhe lower ange 7 is placed against the side or end plates 1, preferably on the side of said plates opposite to the stakes 2.

' all of'these members.

The angle-bar 6 has its vertical flange lying against the lower vertical flange 7 of the Z- bar and its horizontal flange projecting outwardly with reference tothe car-body and so situated with respect to the Z-bar as to form a duct of uniform and approximately rectangular cross-section. The vertical flanges of the Z-bar and angle-bar are secured to the side plates by means of rivets or bolts or other suitable devices 9, which pass through Some of the rivets or other fastening devices also pass through the stakes. This construction of the stilfening member at the top of the side plates practically forms a box-girder and greatly increases the stiffness and strength at the top of the car-body both on the side and end. to resist transverse forces applied in any direction, but is particularly valuable in resisting forces which tend to bulge the sides laterally. As the tendency to bulge is much greater at the center of the car than near the ends, it will not be necessary for economical reasons to extend both flanged bars entirely to the end of the car. One of the flanged bars, therefore, may terminate some distance from the ends of the car-body, preferably at the central vertical transverse planes of the bodyholsters 10. rIhe other flanged bar will extend entirely to the ends of the car-body. The same construction of flanged bars will also be applied tothe top edges of the end plates.

What I claim as my invention, and desire to secure by Letters Patent, is- Y 1. In a metallic car-body,-the combination of the side plates, a strengthening member of vZ-shaped cross-section extending along the top of said plates and secured thereto, and an angle-shapedV strengthening member also extending along the top of said plates and secured thereto, one of said strengthening members being shorter than the other and both of said strengthening members extending along the top of said plates and in parallelism throughout their length.

2. In a metallic car-body, the combination of the side or end plates, a strengthening member of Z-shaped cross-section extending along the top of said plates and attached there- IOO to, and an angle-shaped strengthening member' also extending along the top ofsaid plates and attached thereto.

3. In a metallic oar-body, the combination of the side or end plates, a strengthening member of Z-shaped cross-section extending along the top of said plates, said strengthen-A ing member having its flanges directed vertically and the lower one thereof secured to4 the side plates, and an angle-shaped strengthening member also extending along the top of said plates, said -anglelshaped strengthening strengthening member and having its other I5 strengthening member and the vertical ange 2O of the angle-shaped strengthening member.

In testimony whereof l, the said JOHN M. HANSEN, have hereunto set my hand.

JOHN M. HANSEN.
