To all whom 'it may concern: A

Be it known that I, RICHARD' P. MCCOR- Mioi, Jr., a citizen ofthe UnitedStates, residing at Hort-land, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements 1nv to provide for tilting the car-body at one or both sides, and to have a door at each side. A construction of the doors of'such cars has been such that when the car-body tilts,the

door at the down, or lowest side, opens byraising. This mode of dumping the car and opening the door by raising, has objections one of which is that when large rocks are in the load that is to be dumped. below the raised door, the rocks are liable, as they slide out, to catch or strike against the lowerl y turning down at the time the car-body tilts edge of the raised door. Another objection* is that the material constituting the load when dumped falls very close to the trackrails on which the car is standing, and

therefore is liable to block the track.

One object of my invention is to provide a tilting car-body with a side door that automatically opens by. the door gradually downward. Also when the door is fully openedat any position of the body thejinner surface of the door will be on la plane even with the-top .surface of the car-body bottom.

Another object is to provide a tilting dumping'car-body with a side-door, hinged at its bottom and that opens by its top turning outward and downward, and also to provide mechanism that will operate automatically to fasten and unfasten the doorlatch, to open the door without shock in readiness to dump the load, and after dumping to close the door, 'and nally to lock the car-body-in its elevated position ready for another load. v

The invention isillustrated in the accompanying drawing, in which,

Figure 1 is an end elevation of the improved car whose bodyis shown in the upright position. Fig. 2 is an end elevation of the car but showing thejcarfbody in the dumpingor tilted position, and the door on the lower-most' side ofv the earl opened beinggturned down. Fig. 3 yis a partial side' elevation of the car, the door being closed,

and shows the mechanicaldoor-operating parts as seen in a direction transverse to the views in Figs. 1 and 2. Figs. 4 and 5 are section views through the hinged part of the door and car bottom, takenon the lines 4-4 and 5-5 respectively of Fig, 3. The door in Fig. 4 is, in the closed position, and in Fig. 5 is in the open position. Fig. 6 is a view of one of the brackets carried at each end of the do`or,-it being understood this door is hinged at'its bottom and opens by turning downward. Fig. 7 isv a perspective view of the lever that co-acts with the endbracket carried on the door. Fig. 8^is an end elevation of a part of the car-,body and shows the latter partly tilted preliminary to dumping the load', and the door-latch disengaged from the door preparatory to the latter being opened, but the door still in `the closed portion.

Referrlng to-the drawing the numeral, 1,

designates the truck-wheels standing on the track-rails, the truck-frame, 2, has at each end an I-channel beam and at the sides Yhas a truss-beam; these parts of the car are 'or may be of any well-known or preferred construction. The truck-frame has at each lot" two ends arched braces, 3, 4, at the top apex .of which is a suitable metal box or bearing,

5, (see Fig. 3) through which4 projects a horizontal trunnion or pivot-bolt, 6, that it attached by means of a bracket or clip, 7 to the bottom ofthe car-body, 8; a central beand or'sill, 9, extendsalong the bottom' of the car and has its ends in the said brackets or clips, 7. This construction enables the car-body to tilt to either side.

Two levers, 10, are below the car-body and each has one end pivoted at the center and 'one of 'these levers projects towardvone side of the car and the other lever projects toward the opposite side. The free end of each lever, 10, has a right-angled terminal, 11. yA stop device, 12, is bolted to each of thetwo arched braces, 3, 4, and serves as a seatv or stop-device for the said levers, 10,

and prevents themffrom tilting down too far but leaving them free to tilt upward.` A dog, 13,'is pivoted at, 14, and the hook at its upper end engages the said right-angled terminal, 11, of one lever; a weight, 15, at-r tached Athe dog serves to keep the doghook normally in contact with said terminal; a handle, 16, also attachedto the dog aii'ords a grasp for the operators hand when he desires to disengage the dog-hook from the said terminal. As there are two levers, 5 10, one being for each side so there must be two dogs, 13, one being for each lever. The free end of the lever, 10, is forked or'biurcated at 111, as seen at Fig. 3. The mechanical provision of twolevers, 10, and two dogs, 13, is necessary only when the carbody, 8, has two side doorsone opposite the other so as to tilt and unload from either side. If a tilting door was at one side only of the car, then a lower lever, 10, and dog, 13, at the opposite side might be dispensed with; it would only be necessary to have at that side any well-known means, such as a chain, to preventl that side of the car from tilting up when the loaded car ismoving on the track. The car shown in the drawing has doors at two opposite sides and is provided with means for tilting downward at both sides. As the mechanical means at each side of the car body to automatically open and 25 close one door is the same, it will be sutlicient for Vthe purposes of this description to describe the mechanism at one side and that operates rily one door.

The vert-ical door, 17, has its lower edge hinged to the bottom, manner of hinging will be presently described. A channel bar, 19, extends entirely across the door, 17 from end to end and the ends of this bar project beyond the ends of the door;v a latch-lever, 20, is ivoted at, 21, to the end of the car-body an at its free end the latch has a-down-pointing hook thatengages the said projecting end of the channel bar, 19, on the door, and thereby the door is held closed. The latch, 20, plays in a keeper bracket, 22, on the car-body, and a triplever, 23, is jointed to the latch and hangs therefrom pendant; the lower end of the trip-lever has a foot, 24. At two opposite sides of the hanging t-rip-lever are angleiron guards, 25, secured to the car-body, and these prevent the said trip-lever from swinging too far out. of a-ve'rtical position, 'when the car is being dumped, or being righted to its normal upward posit-ion'. The means for automatically acting on the pendant trip-lever, 23, to cause it to release the latch-hook from the said door-bar, 19, will be present-ly described. Each end of the door carries a bracket, 26, shown separately in Fig. 6.y The upper or vertical wall of this bracket has at its highest part a right-- angled flange, 27, provided wit-h holes for bolts, 28, by which it is fastened rigidly to the door. The bracket also has at its lowest part an arm, 29, that is horizontal when the car-body is in its raised position; this arm projects at a right-angle with respect to the vertical wall of the bracket, a pivot-pin,30,

j projects horizontally from the vertical wall 18, of thecar, and the.

and above the said arm, 20, and an inclined cam-face, 31, is formed on the bracket. The

position of t-he,pivot-pin, 30, is such that a horizontal line drawn lengthwise through the center of the said pin would pass along the lower edge, 32, of the door, 17, as may be seen in Fig. 3; this lower edge of the door adjoins the carvloor. A door-operating lever, 33, has a hole, 34, which takes over the pivot-pin, 30, and turns thereon and thereby said lever may swing vertically at the end and lower corner of the car-body. The end of this lever is`rounded and is concentric with the hole, 34, and atits vuppermost edge, over the said hole, the lever has a lateral prong, 35, with' an inclined face. This lever is shown in perspective in Fig. 7; the swinging end of the lever forms a hook, that 1s, the end is bent U-shape or doubled-back at, l36, and points toward the pivoted end, and this end has a hole, 37, through which a pin, 38, passes to make joint with the upper end of a link, 39, whose lower. end by ymeans of a pin, 40, connects with thebifurcated end, 111, of the lever end, 10,'l below the car body. It is to be -understood that if a tilting door was at one side only of thecar, then in such case, the lower end of the link, 39, need not be pivoted to a lower lever, 10, below the carbody, but may be pivoted to'any suitable object or part below the car-body. A

The operation of the latch and the opening of the door when the car is being dumped, are as follows :-In the drawing the car is illustrated as being dumped or tilted down at the left-hand side. To permit this the dog, 13, at the right-hand side must be released from the terminal, 11, of `the lever, 10; the right-hand side of the car-body may then be pushed upwardbythe men in attendance, and theieupon the car-body will tilt on the pivot-bolt, 6, and the left-hand side of the car-body will go downward. The lever, 10, at the left-hand side can not moveA down because it rests upon the stop, 12; as the car-body tilts down the free cnd of the bracket-lever, 33, will be forced upward by the link, 39, as shown in Fig. thc first eii'ect of this movement will be to cause the foot, 24, of the trip-lever, 23, to come down on the upturned end, 36, of said bracketlever asin Fig. 8, and thereby raise the trip-lever and release the latch-hook from the bar, 19, on the door, 17, and thus the door is `free to tilt on its bottom hinges. At this stage of the movement the lateral prong. 35, of the bracket-lever will have its inclined face in contact with the cam-face, 31, of the bracket, 26, on the end of the door: a still further down-tilting movement of the car-body causes the said lateral prong, to press against the cam-face, 31, and form t-he door to partly open; the door will then turn down on the door hinges andl the bracket, 26, will also )turn until the upward swinging movement of the arm, 29, ofthe said bracket contacts with the bracket-lever, 33; the door will then gradually turn down as the car-body continuesfto tilt'and at last.

when the door is open to its limit it willbe' inclined in the`sa1neinclined plane as the top surface of the bottom, 18, of the tilted car-body, see F ig. 2,and of course the load will at once be dumped. vIt will be seen that the op'en door, 17, when turneddown serves as a slide or chute over which the material composing the loadwill pass; this material is thus kept away from the car-track.V AIt is a feature of thisoperation-that the door opens gradually as the car-body tilts, and it den fall, this vis important as .la fall of *the door would producesuch a 'shockasto break the hinges or produce otherinjury. .When the car-body is pulled 'back from ,its tilted position to the elevated position shown in Fig. -1, the hook-end ofthe latch, '20, will -.be in the downposition due tothe actionof.'

gravity, and the lower edge of the bracketf' lever, 33, will be in contact with the arm, 29,

e (see Fig( 2), and as the lowerlever, 10',

on the left-hand si de is held down by theV dog,'-13, the said l bracket lever) .'33, willf simply turn on the pivot, 30, and as theleft hand side of thecarfbodyj` gradually rises,

the said bracket-leverfby bearmg down on the bracket arm, 29,'will cause the door, 17,

. door, 17, has Y4o to swin bracketle strikesthe tri Jever 23,`and knocks-itI` toward the ri Ethanj side, and' when'the i earlyl closed, its b'ar, "19, will g take underthegroundedfend 'of the `will then, drop andiengage the bar. eThe door is thus raised, closed and-latched, and 5. while these operations are bein done the` lower lever, 1 0, at the right-han slide, and which was ,elevated with the `car-body, has been lowered, and as this lower lever comes down it strikes the rounded upper end of the dog, 13, which will 4swin back oniits` pivot, 14, and-allow the en 11, of said lower lever to pass, and then the dog-will swing forward and engage over the said.

lever-end, 11, which locks thecar-body in its elevated position, asin Fig. 1.

While the car-bodv must be tilted to dump by manual action, and after dumping its load must be pulled back also by manual power, yet all the mechanical operations of the latch to unfasten and to fasten the door, and vto open the door and then to'close it again, and finally to lock the car-body in itsuelevated position, are effected automatica y.

The hinges for the door, 17, are shown in vFigs. 3, 4 andf5. Referring to Fig. 4, the

upward until it closes. 'As the; ver, -33,"'swings 'down from fthe po?A siti'on in Fig. 2,t the position in 14`ig.-.;1=i'/Z lower inside corner edge of the door, and .the upper edge of the car-body floor are `on the axial-line with the pintle, 41, of -the hinges `which areof the ,knuckle-joint type. Each hinge consists of a leaf, 42, having an leaf being secured V.to the outer surface o'f thedoor'by screws, .44, and a second leaf, 4 5, having two rounded knuckles, 46, and secured to .the lower surface of the floor; a notch is cut in the lower edgeof the ,door and :another notch in the edge of the iioor to receive the saidknuckles, .and theipin'tle pin, '41, unites -the said three knuckles. ,Whenjthe door of the car is openand fully straight inclined plate. This construction produces'. a close,.t between the floor and the door, regardless of the. position 1the door mayhave. Any number of hinges may be used onthedoor, I prefer to use'four.

l To facilitate the workofthe men who'are ,loading the car withshovels, the sidedoor to a horizontal'position 'so as. to be level the vdirtV so high.

and any other `part of the mechanism may -be made of metal either. cast, rolled or .forged; it is also to be 'understood that the an arm projecting substantially at a righthas its axis -in alinement with the axls of f the pintles of the door-hinges and said lever provided with a lateral prong which forces the door to open when the lever in oves in in the opposite direction contacting with said right-angled arm to close the door, and a link whose upper end connects with said door-o erating lever and whose lower end is pivote at a point below the car-body.
