FREIGHT-CAB CLOSUBE.

,To all 'whomz't ma concern:

Be it lknown t at I, FRANK J. Grano?, a citizen ofthe United States, residing at Buialo, in the county'of Erie and State of New York, have invented certain vnew and useful Improvements in Freight-Car Clo sures, of which the following is a speciica'- tion, reference being had therein to the acwhat course .willL produce the most money.

for the railway, and .even salva e,4 or the value of discarded or worn out oors is Isometimes a controlling factor.

With these facts in view, the present invention seeks to provide a very inexpensive construction adapted for use on old or new wood doors or on doors of thin sheet steel,

and it especially seeks to provide improved means for the support and lower side engagement of grain car doors where no inside boarding or coo ering is to be employed, and, further, to e iminate the heavy and'expensive castings of malleable iron often employed and yet have a structure which` w1ll not be injured vby the impact of wagon wheels which are often backed against the carin preparing for unloading. j

In the accompanying drawings, `Figure 1 is an elevation of a portion of a wood door and adjacent portions of a car. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 1s a view similar to Fig. .2, showing thel use of a thin sheet metal door.

In Figs. 1 and 2, A represents a wood door, B the side wall of a car, C the car sill,

and D the' car iloor. Along the'lower edge of the door extends a metal channel member E, which receives this side of the door and is secured thereto by bolts E. -From this member depend brackets E2 to receive rollers F, which are preferably slightly conical.

Ak track member of sheetrmetal, bolted yto `,the car, extends,below the doors edge, along the exterior of the 4car to a distance from the door opening not less than the width of the door. This member is formed 4from a primarily plane sheet metal strip having its upper marglnal portion bent outwardly downward to form a hook G for 'receiving the narrow inner'flange of the member E,

and below the rolleris it is bent sharply outward to form an inclined ledge H upon which the rollers may rest. It is then returned and bent sharply downward to restl against the car wall. The upper'and' lower walls of the hollow' rib thus formed may be more or less widely separated and the intervenmg space may be filled with a strip I of l suitable material, oak sometimes being used, 'to increase the resistance to the'impact of the wheels of heavy vehicles used in unloading the car; and it is to be noted that/this rib projects outwardmaterially farther than the hook above, which is thus well protected. The construction allows the lower edge of the door to be engaged from end to end at all times, whether the door beopen or closed,'and it permits the use of light rolled metal in place of the heavy and expensive malleable metal heretofore used in similar constructions. The `closure at the bottom edge of the door is almost hermetic, the inclination of the upper surface of the rib causes water to run oit quickly, and the readily accessible plane inclined surface make it easy to remove such snow and ice 's might interfere with the opening of the oor. f Fig. 3 illustrates a similar construction with a thin metal door J. Here the lower margin of theI door is itself hooked instead of being provided with a channel iron. The rollers in this case are each supported single bracket K riveted to the y'outer of the door. The track rib may project materially less than when a thick door is used,

b et

same way. This form is readily added to any car and as its cost is not greater, it is preferred to the wood door form whenevera new door is needed. What I claim is: .4

1. The combination with acar,of a horizontal metal member lixed to the exterior of the car slightly below the plane of its floor and provided with a continuous flange forming downwardly open hook, a rigid upwardlylclosed rib parallel to the hook, below the same and projecting materially farther from the car wall, and a-door provided at its lower margin with a flange .engaging said hook.

2. The combination with a car, of a track member of sheet metal bent to form at its upper margin a'v continuous4 downwardly open hook and below the hook a parallel upthe car wall,v devices xin the strip to the' wardlv closed rib projec materiali? farthor than the hook from te car wal and having its upper face downwardly and out wardly inchne and fixed to the car below the door opening, and s. door ce, ing rollers to rest upon said rib and provi ed with o marginal hook to engage the hook first men'- tioned. l

3. The combination with a.' om',y of a metal strip bent to form alom its upper margin a continuous downwar open hook una between its marginsy a ho low track rib ma allel to the hook and projecting farther rom exterior of the car below lts door opening,

a, door havin at its lower side a flange engaging said ook, and rollers mount/d on the door and resting upon said rib.
