HOPPER-BOTTOM CAR.

Application filed March 17, 1911.

To all whom it may concern Be it known that I, MINOT C. BLns'r, a citizen of the United States, residing at Euclid avenue, Bellevue, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Tmprove ments in Hopper-Bottom Cars, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in Which v Figure 1 is a side elevation of a portion of my improved hopper bottom car; Fig. 2 is a plan view of the car; Fig. 3 is a sectional plan of the car showing the underframing with floor plates removed; Fig. 4: shows vertical cross sections of the car, the left hand half being a section on line 4-4, of Fig. 1, and the right hand half a section on line l -4, of Fig. 1. Fig. 5 shows a side elevation on an enlarged scale of the bracing between the side walls and center sill of the car, the latter two figures showing the application of the preferred form of my invention. Fig. 6 shows a side elevation of a portion of the car embracing the cross ridge and showing a modified form of the bracing shown in Figs. 4; and 5; and Fig. 7 shows a cross section of the car taken on line 7-7 of Fig. 6.

This invention relates to a new and useful improvement in hopper bottom cars, and particularly to the construction of the center sill and the IIIQthOdOf bracing the center sills to the side construction of the car, whereby the car is comparatively light for a given capacity, as well as being easily and cheaply manufactured.

With these objects in view my invention consists in the construction, arrangement and combination of the several parts, all as will be hereinafter described and afterward pointed out in the claims.

In the drawings, 1 indicates the end sill, and 2 the side walls.

3 indicates the web of the bolster, which is preferably of plate girder form, and extends from side wall to side wall.

4: indicates the top or tension member, and 5 the bottom or compression member of the bolster and 6 the bolster tie plate.

7 indicates short draft sills which extend Specification of Letters Patent.

contents of the car to either side of said center sill when the lading is being discharged. The webs of the center sill are spaced apart by the center brace member 13. The lower edges of the center sill webs are reinforced throughout their length by angle bars 14, 1t, secured thereto.

15 indicates the center hopper-sheets, which are riveted to the center sill, their lower edges being cut at an angle as shown.

The side walls 2 of the car, are so con structed as to act as plate girders. These side walls are stiffened by vertical stakes ex'- tending the full depth of the side wall.

17 indicates the side hopper-sheets, whose upper edges are riveted to the lower edges of the side walls, said side hopper sheets being bent inwardly at 18.

19 indicates the end walls of the. car, and 20 the inclined floor sheets, which are sup ported by the inturned lower edge of the end walls 19, by the-bolster, and by the side walls. These inclined floor sheets extend down between the center and side. hopper sheets, and are riveted to inturned flanges 35 thereof, which preferably extend under said floor sheets.

21 indicates a cross-ridge riveted to the side walls of the car, and to the inclined sides of the inverted U shaped portion of the center sill. The cross ridge is preferably constructed of two inclined plates, connected together by flanges 22, at their upper edges. The lower edges of these plates are reinforced by angles 23, 23, which preferably extend from center hopper sheetto side hopper sheet.

To firmly brace together the side walls, cross ridge and center sills, I employ a tapered gusset plate 24, one side of which is secured to the inner side of the side wall of the car. This gusset plate extends downwardly, passing between the flanges 22, at the upper edges of the cross ridge plates, down to the inclined angle bar 25 to which it is secured. This angle bar extends at an incline downwardly from the lower edges of the side walls of the car and passes through the web plates of the center sill to which it is secured through the medium of triangular gusset plates 16, Figs. 4 and 5. 'To further'brace and, stiffen the lower edges of the cross ridge plates 21, I employ a member 26, shown in the drawings as being of channel form, but which may be of any other suitable section, which extends between the angle bars 23,23, onthe lower edges of the cross ridge plates.

In the modified form shown in Figs. 6 and 7, the angle bar 27 to which the gusset plate 24 is secured, extends at an incline downwardly from the lower edge of the side wall of the car and passes under the lower side of the center sill web plates, being secured to the reinforcing members 1%, 14, and thence to the gusset plate and side wall at the opposite side of the car, to which it is secured. To further brace the angle bar 27, to the webs 9,10 of the center sill, I employ triangular gusset plates 28, 28, which are secured to the angle bar 27, and to the web plates of the center sill.

In the modified form the brace 29 used to stiffen the lower edges of the cross ridge plates passes so close to the inclined angle bar member 27, that, at the point where these members cross each other, they may be secured together, and it will be seen from the drawings, Figs. 6 and. 7 that owing to the longitudinal inclination from the horizontal plane of the angle 27, that the central portion of the member 29 has been bent in such a manner as to form a face to face contact with the upper flange of the angle bar 27, at the point at which they are secured together. I

31 indicates the hopper doors, 32 the hinge butts, 33 the hinge straps and 34 the door operating gear which may be of any preferred construction.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent is 1. Ina car, the combination with a crossridge, of a gusset plate secured to the side wall and extending downwardly between and beneath the top flanges of said cross ridge, and a brace connecting the lower end of said gusset plate to the center sill; substantially as described.

2. In a car, the combination with a crossridge, of a gusset plate secured to the side wall and extending downwardly between .and beneath the top flanges of said crossridge, and an angular brace connecting the lower end of said gusset plate to the center sill; substantially as described.

3. In a car, the combination with a crossridge, of a gusset plate secured to the side wall, and extending downwardly between and beneath the top flanges of said cross ridge, and a brace connected to the lower end of said gusset plate, and passing through the center sill and secured thereto; substantially as described.

4. In a car, the combination with a crossridge, of a gusset plate secured to the side wall, and extending downwardly between 'and beneath the top flanges of said cross ridge, and a commercially rolled angle brace connected to the lower end of said gusset plate and secured to the center sill; substantially as described.

5. In a car, the combination with a crossridge, of a gusset plate secured to the side wall, and extending between and beneath the top flanges'of said cross-ridge, a cross brace connecting the lower end of said gusset plate with the center sill, and a longitudinal brace connecting the lower edges of the plates forming the' cross-ridge, and secured to said cross brace at the point at which they cross; substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

MINOT C. BLEST.
