Specification of Letters Patent.

Application led August 29, 1912. SerlalNo. 717,709.

To alllwhom'it ma concern.'

`Beit known t, at I, RALPH V. SAGE, a citizen of the United States, residing in the borough of Westmont, in the county of Cambria and State of Pennsylvania', have, invented certain new and useful Improve-` ments in Dumping-Cars; and I do hereby :declare the followin to be a full, clear, and

exact description o the invention, such as will enable others skilledin the art to which it appertains to make' and use the same.

My invention relates to dumping cars with special reference'to door-operating and locking mechanism vfor gondola flat-bottom cars, provided with flush doors, orfor other dumping'` cars, and its object is to provide apparatus of theclalss described,pwhch is simple o f construction, chea convenient of operation and easily repaire Y Another object of m invention is to provide mechanism where y a car-door is held ina closed posit-ion by means independent of the lifting connections incase thelifting ."ineans should break or become loosened. :s

.To thisv end the invention consists, generally stated, of a lifting shaft connected to the door, and independent door-locking vmeans operated^bothjfor lockinghand ,un`

locking from the lifting shaft.

In the accompanying drawings forming art of this specification and in which simiar characters refer to corresponding parts :Fligure 1 is a vertical transverse section taken on the line I-Iof Fig. 2 throii h a portion of a car body. Fig. 2 1s a side e evation of my' door operating and locking mechanism, as applied to a flush bottom gondola car.

For the sakey of illustration, I have shown my improvement in connect-ion with a flat bottom-or gondola ear, but the same can be used with a hopper bottom car or any other car with slight. modifications, without departing from the Referring to the various characters of refereiice upon the drawings v:-1 designates the liftm or-opernting shaft which, as shown,

.exten s longitudinally` of the car and is mounted in the outer ends of` the flying transoms which may either becomposed of rolled channels 2, or they may be made of vpressed metal as shown at 3.` These flying transoms are'riveted to the center sills 4 at their inner ends yby means of angular brack- .ets 5,1f they are rolled shaped, or, if they'are car.

the door. his flange 9 may be spirit and essence of myintegra'lly lformed of pressed metal, they are riveted directly to the center sills through their inner Hanges. The outer ends of the flying transoins are shown riveted directly to the lower ends of the side stakes of the These stakes may be lrolled sections of angular form, as shown at 6, or they may be of pressed metal, or of any other rolled or .pressed shapes', if desired.

The corner shedding plate 7 has its upper flange 8 attached to the lower ed e of the side late of the car and has a ower vertical an e9 which forms the 'amb of ent inwardly, if desired, as shown in dotted lines in Fig. -1, so that the door will close against it.

vThe car-door-l() is hinged at 11 on its inner side to the center sills 4, and lis o erated by means-of the door-operating mec anism ycomprising the operating 'shaft' 1 which -has a worm or Winding-drum 12 mountedthereon', connected to the door bracket 13 by suitable liftin means such as a chain 14;` or other tiexi' le connection," which is arranged to wind or unwind upon a worm or barrel 12. The rotation of the shaft in o e direction Winds up the chain and closes t e door, or, 'if rotated y-in the opposite direction, the chain unwinds and opens the door.

In order to lock the door in its closed position and to take the strain from the liftin chains and prevent the door from acci entally opening, I provide one or more latches or' bolts 15 mounted to slide in suitable bearings or hangers '1.6, secured to the lower face of the. door and arranged 'to be projected outwardly beyond the edge of the door bynieans of a spring 17 and, when the door is closed, engage the cylindrical surface of a 'tappet 18 which is mounted on the Patented Jan. 6, 1914. f

operating shaft 1 and comprised of an ana slot 419 iniwhich' is mounted a pin 2() secured to the latch; 15 to limit its movement. Another perforation 21,at the end of the hanger is to allow the escape of air or any foreign material which would prevent the 'ee movement of the latch.

A wea-ring plate 22 is secured to the cardoor within. the hangers between the hangers and the door, upon which the latch plays.

.The voperation of the'device is as follows :--Assuming that the 'door is closed, as

,shown in lfull lines in the drawings :-In'

" order to release the car-door, the operating lshaft l is turned in the direction of the arrow shown in 'Fig V1, and in doing so the straight face of the tappet 18 comes in conv verse direction, which will wind up the chain, and, owing to the rounded end of the' latch, it will be pushed back when it comes to the cylindrical surface of the tappet and after assing the same, the latch will as sume-t e position shown in full linesl in Fig.1 l, whereby the weight of the door at that side will be sustained by the operating Shaft.

Although the shaft is -shown as extendino longitudinally of the car, it may be located transversely, inclined, or in any suitable position, as will be understood by those skilled in this art. vWhile I have shown and described my invention in considerable detail I do not Wish to be limited to the exact details of construction specifed, but may'use such sub-- stitutions, modifications or alterations as fall within the scope of my invention and as pointed out in the claims. Having thus described my invention, what I claim and desire to secure by Letters Patent is v l.
