FLUSH CAR-DOOR.

Specification of Letters Patent.

ratentednpr. so, 1912.

Application filed .Tune 23, 1910. Serial No. 568,554.

States, have invented certain new and use-- ful Improvements in Flush Car-Doors, of which the following is a full, clear, and eX- act description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure l is a plan view, partly broken away and in sect-ion, of a portion of a gondola car with my invention applied thereto. Fig. 2 is a side elevational view, partly in section of a portion of the car shown in Fig. l. Fig. 3 is a sectional view on line 3-3 of Fig. l. Figs. 4l and 5 illustrate modications.

One object of the invention is to provide car door operating means positioned wholly below the plane of the door when said door is closed, so as to provide an unobstructed discharge opening when the doors are openV and which can be actuated by a shaft carried in a plane below the closed door.

A second and independent object of the invention is to dispense with creeping shafts extending throughout the length of the car, adapted to push the doors to closed position and further, to dispense with grav-ity latches or hooks for locking said doors in closed position.

Another object is to provide means for positively locking the doors in closed position and to secure positive release of such locking means and for opening of the doors when desired to discharge the load.

Another object is to so connect some of the operating parts positively with the door as to insure not only release of the locking means, but also movement of the door independent of gravity in opening so as to break any ice seal which may form in cold weather.

I provide operating means adapted to be v supported entirely below the floor line of the car, which operating means may be readily applied to cars in service as well as to cars when building.

To that end the parts are designed to per- Y mit of ready application to the car by relatively unskilled labor, and are so applied that when the doors are fully closed said doors must be positively locked in closed position by the same means employed for lifting.

For convenience of description the center or centrally arranged sill or sills is hereinafter called center sill, and the side wall o r side plate girder is called side sill because such side wall or girder, whether used merely as a load confining member or as a load supporting and load confining member, in nearly all modern cars, is prac-r tically a support for some part of the load or superstructure. positively locking or positive lock is used it expressly excludes such locking means as depend on gravity for some part of its or their operation.

I have given only suii'icient illustration to make the construction and operation of my device apparent, but it will be understood that t-he construction is identical upon either side of the center sills and that any desired number of doors may be employed. I shall, therefore, describeonly one of the sides. Y

Referring to the drawings by numeralsl indicates the center sill, 2 the body bolsters and cross bearers, and 3 the side sills or. girders, as of an ordinary gondola car. The side walls or supporting girders 3 may be of any suitable construction with an in wardly turned horizontal flange as 4; at the lower edge thereof and extending substan tially throughout the length of the car, or within the Zone of the movable doors.

Arranged to swing upon pivots in suitable brackets 5 supported upon the center sill is a series of drop doors G. The pivotedges of the doors are over-lapped and protected by the overhanging edges of the center sill cover-plate, as at 7. The free edges of the doors extend, when the doors are So also where the term closed, to position beneath the inner edge of the inwardly turned flange 4 of the side girder.

Extending through apertures in the body bolsters or cross-bearers and. supported in suitable bearings 8 adjacent the center sill is an operating shaft 9 which extends beneath all of the doors and to the end of the car as illustrated.

A suitable hand-operated or power mechanism, of any suitable type as 10, is arranged at the end of the car and connects with the shaft 9, for operating the same.

Beneath each of the doors 6 and fixed upon the shaft 9 is a pair of door operating arms 11. rThe free end of each of the arms 11 is bifurcated and fitted with a pin 12 for engaging the slotted end of one arm of a bell-crank lever 13 so as to form a toggle connection therewith. The bell-crank lever 13 is pivoted, as at 14, upon a hanger 15, which projects downwardly from the under face of the door 6. The other arm of the bell-crank extends to a point adjacent the under face of the door and is received in a pocket or notch, as at lf3, formed at the inner end of a locking rod 17. rlhe rod 17 is slidably mounted upon the under side of the door and suitably supported and connected thereto at its outer end as by sleeve 18. The inner end moves between and is retained against lateral play by the two members of the hanger 15. The outer end of the rod may be formed with suitably arranged teeth, as at 19, for engaging coperating teeth on a roller 20, mounted in a bracket 21, fixed to the lower edge of the side girder.

When desired, a spring plate 23 may be fixed to the inner face of the center sill and when employed is impinged by the inner end of the lever mechanism and absorbs the shock of the door as it drops to its lowest position.

In operation: The rotation of the shaft 9 in a contra-clock direction, Fig. 3, will raise the door from the position shown by dash lines to almost the position shown by the heavy dots, with only slight movement of the bell-crank lever relative to the door. As the shaft is turned to position shown by heavy dots, the bell-crank is moved upon its pivot so as to bring the toothed end of the locking rod into engagement with the roller 20. rl`hus far the pin 12 has been in engagement with the end of the slot in the arm of the bell-crank 18. rlhe centers of the shaft 9, pin 12, and pivot 14, are now in alinement, so that the door is raised to the highest position possible through the direct lifting action of arms 11. A, continued rotation of the shaft 9, however, will turn the bell-crank lever about its pivot so as to force the locking rod 17 outwardly. As the teeth 19 on the under curved face of the end of the rod ride on the roller "20, the door will be forced to the position shown in full lines, where it is positively locked and all strain relieved from the lifting mechanism.

ln the construction shown in Fig. 4, the roller Q0 omitted and a stationary support 22 is substituted therefor.

Fig. 5 is similar to lfig. 4 except that the end of the locking rod is stepped so as to more positively support the door when the parts are in the position shown by heavy dots in Fig. 3.

Thus it will be observed that the operating parts are all positively operating parts so assembled that the door may be first closed, as the term is generally understood, and then tightened so as to prevent accidental escape of the load, and, while being moved to their final position, the locking means are brought into coincidence so to positively lock the doors in final closed position without the interposition of any movable means depending from the car side or side sill. This final closing, or tightening, of the doors is desirable and, where fine coal or grain is carried, quite necessary to prevent accidental discharge of part of the load.
