"ie'it'lniown that l, ARTHUR G, McKee, a

citizen "of thellnited' States, residing at Cleveland, inthe count-y lof Cuyahoga and *S'ta'te'o'f Ohio, have :invented a certain. new

"and useful'lmprovement in- Cars, of which thefffollowing is ay full, fcleai', and exact dey scription.

{CE-he object` ofthe `present invention is to provide an. improved car with .a bottom dis'- charge, having suitable construction which sha-ll permit it to be readily and completely j 4emptied of its loadwhile .entailing the mini? inum'fef edfort onthe part of the operator. f

'l have, however, devised aii'aiA rangement whereby't-lie door may be'instantaneously released and opened byl the .open atei' with small edort and the vdoor allowed to move entirely back and away from the opening so as to 'allow the material freie passagefrom' vthe 'car,'and by .which the door is closed easilyA andwithout the use' of 'great force.

.is aside View of the car shown in Figs. l andQ. Fig. d is a cross section of a car prolvided with a modification of the operating mechanism for opening and closing the door. Fig. 5 isan end view of a portion of a car providedwith a pair of doors which are connected together so as to be simultaneously operated., f'

yThe car itself may be of-any desired construction, though` preferably it should be of lthe forni 'shown-that is provided with converging downwardly sloping side walls, one or both of which may be shortened so that the lower or V point of the car is formed by veither a single door and one side' wall, or by `a pair of doors, such as lshown in Fig. 5. Obviously, With such'construction, when the door is moved away from its closed position, .the 'car may be 'completely emptied` lt/will be noted that in the various emf These links are secured l from the. point at which it is when 'the door is in closed'positio'n. This is a' feature of structure which obtains in every forni of my construction, and which is had ,with every niodication `of operating mechanism by,

which thel door may be opened or closed.

By reasonl of the dooi1 being suspended in this manner, itr would, of course, require some edort to open the same, since the pull of gravity would 'be in such a direction as to y cause it to normally swing to a closed position, and inasmuch as doors and their parts are very heavy, it shouldv be' seen in constructing these cars that the rise of the center of gravity is not too great. The weight of theload in the car, however, is a factor to be taken into consideration, since this load will tend to swingtlie car open until ysulficient spaceisfgiven for thenmaterial vin the can to falltherefrom: and, as this load is normally quite heavy, means should, as a .matter of fact, be provided to liold'the door firmly closed. The means which I employ for this last named purpose is,lpreferably, toggle links B B, such as shown in .thevarions figures, which have great capacity for resisting thrust pressures.

For the operation of the toggle links I nay provide, as shown in Fig.1,a `shaft C 'through the end of'that toggle link -B which is pivotally connected to the door, which` shaft is keyed to the toggle link and isalso keyed to an operating lever C on the-outside of the 'car at one end thereof, as shown in Figs. 1, 2 and 3. In Fig. 2 the position of the operating lever is'shown as that in which the door is closed, when the lever is' .mit thetoggle link to straighten out under the tendencyl of the door to swing downwardffthe structure being,as above stated, such that the center of gravity of the door and its appurtenant parts is at its lowest position when the door is closed. Thus, it is possible for these very heavy structures to be handled lwith ease by a single man without any sacrifice of effectiveness asa closure or the free full opening of the door is made to permit a rapid discharge of the contents of the car. To one familiar with the massiveness and cumbersome character of the apparatus these advantages will ap.- pear to be of great value.

In the -form of operating mechanism' shown in Fig. 4, I show the use of the counterweight D rigidly connected with the link B of the toggle farther from the door, so

4hung as to tend 'to break the toggle joint and thereby assist the operator in the first movement of opening-the door. For the purpose of breaking the -toggle in this structure, I have provided'a draw rodI E pivotally connected to the pin `E `of the. toggle knuckle, which rod passes upward through a guiding and'retaining bracket E2 on the side of the car,-a handle E3 bein secured into the upper end of the rod to a ord convenient means for the operator to draw the same upward in order to effect the breaking' of 4the joint.v In` order to lock the parts in any .desired position, a quick acting screw -E- having an operating lever .Ei on the-end thereof is mounted in the side of the guide bracket in such'position that it may be forced against the side of the draw vrod and. n

It will be noted that atthe lower end of 35 one of the doors I provide an angular-ly disposed lip G, placed so as to extend across the line of juncture of the lower edges of.

the' two doors, and thus check'the material in the event of an imperfect alinement of d the meeting edges which might permitine particles to seep out between the doors.

KIVhatever may be the modification of the operating connections, however, v.it be-` seen -that at closure constructed according to my invention will be capable of sustain` v any probable load and yet .be capableof be-v ing swung clear ofthe, discharge` opening so as to permit a "freepassage ofthe con'- tents of the car therethrough, and this -with .109.'

Having described my invention, Iclaim 1. In a car having slanting sides ,and an j .opening inone of'said sides near "the bottom thereof, a doorfor closin said opening, links pivoted to: each end o? the door and to the end ofthe "car body, said door being so hung that it closes byvits own gravity.

'2. In a car lhaving slanting 4sides and an opening in one of said sides near thebottom" thereof, a door for closing-said opening, links pivoted to eachfendA of the door and to the endof the car body, said door. being so hung that it closes by its own gravity, means -for securing said door, said door belng op'- erableto -befop'ened by the load'when the securing means isreleased.

3. In a car having a `discharge opening at i or said opening,a`pair .oflinks secured by `one-.of their ends to each'endv of the door and at their .other ve'nds--piv ted upon the ends .of the carbody, a togglelever securediat one of minnie to axed part of the em", and means for holding the said toggle thereby to hold the door in closed position.

Y t, In near having a discharge opening at 5 thelowei end thereof, a door for said openingsuspended and controlled by a pair oi links at each end pivotally connected near its respective sides, said links being connected'to allowr ,the door an 'outward movement 10 away from the opening, said door being hung so that its center of gravity is raised l during its initial opening and final closing movement, mechanical means for moving the door inward and outward, and a counter Weight for said dcoi` located to counteract 15 v:i portion of lthe load upon the operating connections In testimony whereof, I hereunto alix my signature in the presence of tivo Witnesses.
