DROP-BOTTOM CAR.

Specification of Letters Patent.

Patented Nov. 22, 1910.

Application filed January 25, 1909. Serial No. 474,063.

To all whom it may concern:

Be it known that I, ANTON BECKER, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Drop-Bottom Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in drop-bottom cars,--an object of the invention being to provide simple means for opening and closing the hinged drop doors and afford substantial support for the same when they are in either open or closed position.

A further object is to provide means which can be operated to open or close onehalf the drop doors simultaneously.

A further object is to so construct the door operating mechanism that it can be easily applied, and removed if necessary.

A further object is to provide door operating mechanism for drop bottom cars which can be easily and quickly constructed and in which the use of complicated parts shall be avoided.

With these and other objects in view, the invention consists in certain novel features of construction and combinations of parts V as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view partly broken away of a portion of a car bottom embodying my improvements. Fig. 2 is a side elevation partly broken away. Fig. 3 is an end view. Fig. 4 is a section on the line a-m of Fig. 3. Fig. 5 is an enlarged, partial transverse sec tion showing the door operating mechanism. Fig. 6 is a section on the line y-y of Fig. 5. Fig. 7 is a section on the line a-z of Fig. 1. Fig. 8 is a section on the line a-a of Fig. 5 with the door operating means removed, and Fig. 9 is a view of a modification.

1 represents a center sillof the box type and 2 the draft sills connected with the end thereof. A series of transverse members comprising cross-bearers 3 and holsters 4 are secured upon the center sill and between these transverse members and the center sill, reinforcing plates 5 are secured to both. The transverse members are preferably made in the form of channel beams and are provided with channel beam cover plates 6 having their flanges projecting downwardly. The outer ends of the cover plates 6 have secured upon them, side sills 7 which may also consist of channel beams. Side stakes 8 are secured to the inner faces of the side sills, project downwardly through the cover plates 6 and have their lower portions securely riveted to the outer ends of the transverse members 3 4. The side sills 7 extend from one end sill 8a to the other. Angle bars 9 are secured to the lower portions of the side sills and extend from the bolster 4 to the end sill and these angle bars are connected a short distance rearwardly of the end sill 8 by a transverse angle-bar 10. A cover plate 11 is secured at one edge to the end sill S and at its other edge to the anglebar 1() and to the ends of this cover plate the forward ends of the angle-bars 9 are secured. This construction gives rigidity to the corners of the car. End stakes 12 are secured t0 the transverse angle-bar 10 and, projecting downwardly therefrom, are secured at their lower ends to the draft sills 2. Sub-sills 13 are located under the side sills 7 and are secured thereto and to the cover plate 11 to stiffen the corner construction and the latter is further reinforced by the push-pole pockets 14.

Buiing blocks 15 are secured to the end sills and each of said buiiing blocks is provided with flanges 16 which project rearwardly and are secured to the forward ends of the draft sills 2. Drop doors 17 are located between the transverse members at respective sides of the center sill and the hingepins 18 for these doors have their mountings in the depending flanges of the cover plates 6 on the transverse members. The hinges for the drop doors may comprise straps 19 secured to said doors and connecting the same with the hinge-pins and the hinged edge of each door is reinforced by means of an angle-bar 20. The doors may also be reinforced lengthwise by means of bars 21.

The transverse members are provided near their ends with recesses 22 for the accommodation of a straight shaft 23 having rollers thereon to engage the drop doors. Arms 24 are secured to the shaft 23 and at their lower ends these arms have bearings in hook shaped hangers 25 secured to and depending from the transverse members 3 4. It is apparent that when the shaft 23 is in the position shown in Fig. 5, the arms 24 will be verwith the vertical Walls tically disposed and the dropdoors will bev 24?- Which may have bearings in the end sills and be adapted for the reception of a suitable lever for turning the same to raiseor Vlower shaft 23 for closingv or opening the doors. llVhen the doors are in their closed position, as shown in Fig. 5, a lmovement of the shaft 2.3 downwardly 4through the recesses 22 of the transverse members will permitfsaid'doors to open and as the doors approach` their opening position, las indicated by kdotted lines in Fig. 5, the hook shaped ends of the hangers 25 will enter and pass through openings 2.6 fin-the arms2t and thus the doorsy Will be support-ed in their open position and disengagement of the arms 24 from the hangers 25 Willv be prevented. When thel shaft 23 is moved upwardly for eifectingfthe -closing of the doors, the vertical position of the arms 24--to properly support the doors in their closed position, Will be insured by the venga-gement of the shaft 23 of the recesses 22 in the transverse members-said vertical Walls of they recesses 'th-us constituting stops.

ne or more arms 24 of each shaft 23 has secured thereto a sprocket Wheel 27 and smaller sprocket Wheels 28 are secured upon a shaft 29 mounted in the transverse membersof the underframe. The'sprocket Wheels 27 4and 28 are connected by sprocketchains The shaft .29. is made inl-two sections and each section may be geared with the door operating means-at both sides ofthe center sill. The outer-end of each shaft section 29 projects beyond fthe end sill of the car and is provided Wit-h lratchet lever mechanism 31 for rotating it.

From the construction and arrangement of parts above described, Vit Will be-seen that When one of. the shaft sections 291is opera-ted, motion Will be transmitted to door operating shafts at both sides of the car and thus one half of all the drop doors of the car can be o pened or closed simultaneously. To operate thesother half of-all fthe-doors, it is simply necessary to rotate the other shaft section 29 by means of lever mechanism at Vthe-oppoy; site endof the ear.

With :my improvements the door .operating devices-can be readily lplaced in position on the open hangers 25 or removed therefrom if necessary for repairs and when the mechanism. is in use, it cannotaccidentally escape Y from the hangers.

If'tdesired, the transverse members may be shortened and the recessing of said members obviatedasshown in Fig. 9. With this construction, the cover plate-6 is made to ex- The shafts 23 arel provided at the ends ofthe car with arms `cover plates for the latter,

tend to the side channels 7 with the side stakes 8 connected to the top of the cover plate.
