CAR-DOOiR-OPERATING DEVICE.

Specification of Letters Patent.

Patented Nov. 11,1913.

Application filed July 3, 1912. Serial No. 707,637.

To all whom it may concern Be it known that I, VIo'ron .MQ SUMMA, residing at .St. Louis,Missouri, and being a citizen of the United certain new and useful Improvements 1n Car-Door-Operating Devices, (Case A,) of which the following is a full, clear, and or;- act description, such as will enable others skilled in the artto which it appertainsto make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the inven tion, though it is to be understood that the details obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a transverse sectional view taken on line 1, 1 of Fig. 2; that is, taken transversely through a car longitudinal sectional view section beingtaken on line 2, 2 of Fig. 1.

The object of the invention is to provide doors, which will positively lift and will their closed position, and which will unlock and positively release the doors when they are in their closed position.

Referring to the parts; F indicates a center sill or central girder, which may be of any approved type of construction.

H represents generally a cross-bearing member commonly incident to car underiirame constructions, which is connected with the :center sill by means of rivets G, passing through the flanges otthe members H and through the webs oifthecenter sill.

I is abottom wtie plate connected withthe idiaphragms H {and extending below :the cone ter sill.

B B indicate angles which are commonly States, have invented 1 described, as it is and Fig. 2 is a 01 the car, the

"lifting and locking and re leasing device, adapted to be applied to the hinged doors of dumping commonly known a as general service cars, the principal object being to arable and eliicient means for operating the cars, of .the class provide simple, du-

lifted to a oft-he brackets 1, within which are slidably mounted locking bars l. bars are preferably formed These locking each of a single piece bent back upon itself, as shown in Fig. 1, to form loops 5, and are of suflicient length to project be end the outer edges of the doors to form locking bolts 6, which locking bolts are adapted to pass through loops in the hangers 7 which hangers are :secured in position by being projected through the horizontal flanges oil .the angles B, before referred to, and held n positlon by nuts 8 on the upper ends of said loops 7. Connected with the cross-bearers H, in

any preferred manner, are bearings 9,which form seats for the-crank arms 10 of shafts 11, which shafts are rockable in the bearings 9 and within the loops 5, before referred to.

Assuming the door S to be open, as shown at the right-hand SldQzOf Fig. 1, the shaft 11 as indiis rocked in a clock-wise direction,

icatcd by the dotted l1ne and arrow 111 Fig.

1. This rocking ol the shaft 11 will cause retraetionof the bolt 6 through engagement ofthe loop 5 with said shaft until the-door reaches a horizontal position, at which time continued rotation of the same direction Will cause the bolt 6 shaft 11 in the to be projected beyond. the outer edge of the door and into engagement with the loop 7, before referred to, and at the same time the shaft 11 is relieved from the weightoi the door and the door is supported by locking bar 6 engaging with the loop 7 When it is desired to open the door, the shaft 11 is rocked in an opposite direction, the shaft cooperating with the loop 5 to retract the bolt 6, thereby permitting the door to drop by gravity, but if, for any reason, tie door should stick and refuse to drop by gravity, the interengagement of the shaft 11 and loop 5 will cause the door to be pulled downwardly, so as to break any seal (such as an ice seal) which may have been formed.

It is to be observed that the doors S are not pivoted to the center sill or center girder F, but are supported upon brackets 15, which are riveted directly to the web of the center sill, and are so proportioned with relation to the top flange 16 of the center sill that the inner edges of the doors in closing will be carried some little distance below said top flanges 16, thus dispensing with the usual sill cover plate, which is common in car constructions of this type.

It is to be observed that the forward eX- tension 5 of the loop 5 will abut the rear inner edge of the bracket 1 when the bolt 6 is fully projected, thereby preventing rotation of the shaft 11, which rotation, if permitted, would allow the door to drop.

What I claim is 1. In a car, in combination with the frame of a car, a pivoted door, a shaft pivotally mounted adjacent the door bearing against and supporting said door and sliding mechanism carried by said door, whereby said shaft revolving in opposite directions, moves the door in opposite directions.

2. In a dumpin car, the combination of a side tension angle having a door supporting loop secured thereto, a pivoted door, a bracket fastened to the underside of said door, a locking bar slidably mounted in said bracket, and adapted to be projected beyond the adjacent end of the door into said loop, and a rockable shaft in constant engagement with the loop.

3. In a. dumping car, the combination of a side tension angle having a loop secured thereto, a pivoted door, a bracket fastened to said door, a locking bar slidably mounted in said bracket, and adapted to project be yond the adjacent end of the door into said loop and means beneath said door to actuate said locking bar.

4. In a dumping car, the combination of a side tension angle having a loop secured thereto, a pivoted door, a bracket fastened to said door, a locking bar slidably mounted in said bracket, and adapted to project beyond the adjacent end of the door into said loop and a swinging shaft actuating said locking bar.

5. In a dumping car, a hinged slidable bolt having an outer edge to project from an edge of said having the inner end bent into a door, a adapted door and loop and door actuating means engaging said loop thereby to actuate the bolt.

6. In a dumping car having a holding loop, a hinged door, a bolt carried by said door, means positively actuating said door in both directions, said means connected to said bolt to project the same into and from said loop.

7. In a dumping oar having a holding loop, a hinged door, a bolt carried by said door, means positively actuating said door in both directions, said means connected to said bolt to project the same into and from said loop, and means limiting the outward movement of said bolt.

8. In a dumping car, a door hinged along one edge, a locking means carried by said door adjacent the opposite edge, door actuating means moving in an arc in a plane at right angles to said hinged edge and engaging the underside of the door, said means directly connected to said locking means to actuate the same.

9. In a dumping car, a door, a rocking shaft movable in an upward direction and directly supporting said door and door looking mechanism carried by said door and actuated by the outward movement of said shaft.

10. In a dumping car, a door, a rocking shaft movable in an upward direction and directly supporting said door and door locking mechanism carried by said door, said locking mechanism constituting the means for positively lowering said door.

11. In a dumping car, a hinged door, locking means carried by said door, a rocking shaft movable in an upward direction to actuate the door and an outward movement of said shaft actuating the locking means.

12. In a dumping car, a hinged door, looking means carried by said door, a rocking shaft movable in an upward direction, the said movement of said shaft actuating the door and an outward movement of said shaft actuating the locking means, and means limiting the rocking of said shaft.

13. In a dumping car, a hinged door, a bolt carried by said door and a crank shaft directly engaging said bolt to actuate the same.

14. In a car door mechanism comprising a crank shaft adapted positively to actuate the door to open and close the same, and a locking means continuously actuated by the movement of said shaft.

15. In a dumping car, a hinged door, a crank shaft supporting said door and means directly connected to said shaft for locking and unlocking said door.

16. In a dumping car, a hinged door, a crank shaft supporting said door in all of its positions and longitudinally slidable locking means carried by the door loosely engaged by said shaft to open and close said door.

17. In a dumping car, a hinged door, a locking means carried by the door and a crank arm connected to said means and adapted to positively lower the door.

18. In a dumping car, a hinged door and 1 a two-part mechanism constituting pivot In Witness whereof I have hereunto set my hand 1n the presence of two wltnesses.
