To all 'whom t may concern:

Be it known that we, FRANK L. IRWIN and JOHN E. nssnrMAN, citizens of the United States, residing at Columbus, in the county of Franklin and State of Chio, have invented certain new and useful Improvements in Hopper-Cars, of which the following is a specification.

Uur invention relates to improvements in hopper 'cars and has especial reference to the construction of a cross hood between the hoppers and the manner of` securing the same to the sides of the car and of reinforcing the said hood, tand strengthening the car construction at this point.

The form of cross hood especially included herein comprises sloping side sheets' which do not meet at their upper ends and an apex or ridgeV member applied to the said upper ends and formed preferably of a single piece of metal pressed to form a thereof and having sloping sides which overlie and are secured tot the upper ends of the side sheets of the cross hood. vAnother feature of the cross hood construction is a bracing diaphragm disposed between the sloping sides of the cross hood and extending from the center sill to the outer end of the cross hood and being connected with an angle brace which extends across the cross hood and is secured to the sloping side sheets which will appear in the more detailed description hereinafter.

In the drawings which are hereto attached and hereby made a part of this speciication, Figure 1 is a vertical longitudinal section through one end of the car between the center sill and the side of the car; Fig. 2 is a vertical transverse section A-A of Fig. 1 between the end slope sheets and cross hood; Fig. 3 is a side view of the reinforcing member applied to the car at each side of the center I longitudinally inside of the hood. Fig: 4c is a top view ofthe cross hoodl illustrating the application thereof to the center girder construction. Fig. 5 shows in detail the construction of the reinforcing member and its connection with the other features of the car construction, and is a section taken along the line M-M of Fig. 6. Fig. 6 is an enlarged detail of the cross hood in vertical transverse section, omitting the center girder and extendingL girder construction and means of attachment thereto. A

In the drawings, 1 is the center girder construction formed, in this instance, of the parallel channels with their flanges inwardly disposed; 2 are the end slope sheets' 3 is the side of the car; 4 is the centei` sili hood traversing the car longitudinally and having its lower edges flanged at -5 and 6 and applied to the vertical webs of the ce'r'iter sill channels and secured thereto at 7 and 8. At one end the center sill hood is secured to the end slope sheets at 9 generally in a well known manner not illustrated,

and at the other end flanges 1() and 11 are formed on the center sill hood and applied to the cross hood, being secured thereto at 12 and 13. 'y

The cross hood is formed of the oppositely inclined sheets 14 and 15 having at their lower edges respectively the angle braces 16 and 17 riveted thereto at 18 and 19, whereby the lower edges of said sheets are reinforced. Angles as shown at 20 are applied to the center sill and secured thereto by rivets as shown at 21, and are also secured to the inner end of the cross hood sheets 14 and 15 by rivets as appears at 22. It is seen that the upper ends of the sheets 14 and 15 do not meetLand we provide a ridge orl vcover member which is formed of the sheets 25 and 26, having the diverging sides or flanges which overlap respectively the upper ends of the inclined sides 1li and 15 of the cross hood and are secured t ereto by rivets as appears at 27 and 28. Sheets 25 and 26 have upwardly extending flanges 23 and 24, projecting above the center sill cross hood, and are secured together by the rivets 29. This construction is very strong and provides reinforcement for the cross hood at points where great strength is required.

' At the sides of the car are provided inside side stakes formed of the angles 24 and 24" which have wide inwardly projecting flanges as appears at 24, having their lower ends inclined outwardly as appears at 24:d and secured by rivets atI 24 to the flanges 23 and 24, thereby securing the cross hood construction to the sidesI of the car. It will be iinderstood that a similar construction is provided at the opposite side of the car.

An outside side stake is shown at 32, the flanges 31 of whichare riveted as at 30 to the side 3 of the car and the flanges 24a and 24b of the inside side stake. An angle 33 1s secured along the lower edge of the side of the car by means of the rivets 34 which pass through the u turned flange of said angle and the side o the car and the flange of the outside side stake 32. The angle 33 is utilized in connection with the bracing of the cross hood as appears hereinafter. At 35 the sheet 26 is flanged and is applied to the side of' the car.

A bracin angle 36 bent outwardly at its ends 37 and 38 is secured to the cross hood sheets 14 and 15 and abuts at its ends against a flange of the angles 16, 17, whereby a rigid braceis formed transversely of the cross hood. We also provide a reinforcing diaphragm 39 shown especially in Figs. 3 and 5, which is flanged along the edges 42 and 4.3, and secured through the flange 40 by rivets 41 to the center s1ll and by rivets 46 to a tension member 44 which overlies the cent-er sill and is secured thereto at 45, and by rivets 49 dia hragm 39 is secured to a compression mem er 47 underlying the center sill and being secured thereto at 48. An angle member 50 riveted at 51 to the center sill is secured at 52 to the diaphragm 39.4 At 53 is provided an angle member secured to the diaphragm 39 at 54 and to the side of the car at 55. The flange 56 of the side angle 33 arranged on the lower edge of the side 3 of the car is secured at 57 to the compression member 47, and rivet 58 secures together the bracing member 36, the compression member 47 and the flange 43 on the diaphragm 39, whereby a very strong support is secured for the cross hood construction, binding the same to the diaphragm and to the side of the car, such that the stresses set up in the use and operation of the car will be absorbedto a very great extent; and since the hood and the related parts are secured to each other and to the sides of the car and to the center sill, the construction has great strength.

The features of our invention herein are seen to be therefore a cross hood formed of sloping side sheets connected at their upper" ends by a ridge member with 'diver lng sides, means for securing the ridge mem er to the sides o-f the car, and means for securing the side sheets to the center sill and to the sides of the car, and the bracing construction provided within the hood both transversely an(7 longitudinally thereof.

What we claim is:

l. In a car havin a center sill, across hood formed of sloping side sheets, a brace member Within said hood secured at its ends to said sloping side sheets, and a reinforcing diaphragm within said hood secured to the center sill, the brace memberand the side of the car, and a tension member applied to the center sill and said diaphragm.

2. In a car having a center sill and cross hood formed of sloping side sheets spaced apart at their upper edges, a brace member placed transversely in said hood and applied at its ends to said sheets, and a reinforcing diaphragm within said hood superposed upon said brace member and secured thereto and to said center sill.

3. In a car having a center sill, a cross hood formed of sloping side sheets spaced apart at their upper edges, a transverse brace member in said hood having its ends downwardly divergent and applied to said sheets near their lower edges, and a reinforcing diaphragm arranged longitudinally of said hood and bearing upon said brace member and being secured thereto and to said center sill.

In testimony whereof we affix our signatures in the presence of` two witnesses.
