To all whom it may concern.-

Beit known that we, JOSEPH ADAM BOUR- GEOIS and JOHN ALBERT BOURGEOIS, both citizens ofthe United States, and residents of Algiers,r in the parish of Orleans and State of Louisiana, have invented a new and 11nproved Oar-Door, of which the following i's a full, clear, `and eXact description.

'this invention relates to car-doors and ro the object of the invention is to produce a door which may be readily opened and closed andwhich-will be substantially water-tight when in its closed position. The invention consists in the constructior and combination of partsto be more fully described hereinafter and`particularly set forth in the claims. Reference is to be had to the accompanying drawings, ,forming a part of this specification, which similar characters of reference lindicate corresponding parts in all the fig- UIBS.- .",Figure lis a side elevation of a portion of thebody of a car provided with a car-door of '.our invention. Iig. 2 is an' end elevation of aportion of the car and representing the door in its open position. Fig. 3 is an enlarged side elevation showing the door and the adjacent portion of the ear and 4representing the 3 door vin itsclosed position. Fig. 4 is a vertical section on line 4 ft of Fig.` 3., but representing the door in the act of beingopened. Fig.

5 is a view similarto Fig. 4, but representing the door in its closed position.v Vlig. 6 is a vertical section taken on the line 6 6 of Fig. 7 and illustratin la bracket which is used .in connectionl wit I the door, and Fig. 7 is an elevation showing the inner face of the bracket., .4 uw; l M 4 A Referring more particularly to the parts, l represents the car-body having a doorway 2 in the side thereof. This doorway is `formed with a beveled lower edge or sill 3 an da beveled lintel or upper edge 4. The side edges o`r jambs 5 of the doorway are also beveled, `as

indicated. .A

vAt a suitable point above the upper edge of the doorway we attach a track, which comprises a cleat 7, attached to the side of the car, 5 to the outer facewhereof a rail S is attached. -This rail consists simply of a piece of strap iron or steel, and vit projects, as indicated, above and below the upper and lower faces of the. cleat 7. These faces of the cleat are preferably beveled so that the cleat tapers .5 5 toward the rail, as shown infliig. 5. l'he door 2 is supported upon hangers y9i, which consist of vertical straps forrncdfinto yokes at their upper extremities and having rollers 10, which run upon the railS, as indicated. 6o 'Ihc lower portions of eachf-of theseV yokesis, bent inwardly to form an inclined extension' or stop 11, which limits the outward ,swing-v ing movement of the door in a manner which will be describedmore fully hereinafter.'65V

The body of each of the hangers 9 is subst antiallyvertical and the extension 1l.` inclincs inwardly toward vthe doorway, as shown. Preferably at the angle of meeting of the 'extension 11 and the body of the hanger each- 7o hanger has pivoted theretoa link 12, and

j these links are attached pi'votally at their inner extremities yto the outer face ofthe door 2, as shownf` y j Below the lower edge of the doorway we attach a pair of brackets, 13, the construction f of. which is very clearly shown in Figs. 6 and 7.4 Each bracket presents a face-plate 14, which is held against the side of the car and is formed above into a socket l5, thebottoln 8o 16 whereof inclines downwardly toward 'thel car-body.l The outerl extremity .of they bracket terminates in an upwardly-projecting finger or guard 17. l

On the lower portion of the door 2f* we 85 attach a transverse horizontal vshaft 18, which is rotatably held in suitable bearingclips 19. The extremities of this shaft are offset to form cranks 20, to which pitinenor connecting-rods V21 are pivotally attached, 9o and these connecting-rods attach pivotally to vertically-sliding bolts 22, which move longitudinally in suitable guide-clips 23, ate taclied to the door. Near itsI central point the shaft 18 is vprovided with arigdily-at- 95 tached lever '24, the said lever being provided With slots 25 and 26. This lever is adapted to lie lat against the outer face of the car-door either projecting upwardly, as indicated by the dotted lines in Fig. 3, or loo rojecting downwardly as .indicated in full ines. Cooperating with the slots 25 and 26, staples 27 and 28are provided. Upon eitherof these sta )les a padlock may be applied in order to lock the bolts 22 in a fixedv position. 105 The cranks 20 and the lever 24 lie substanned by tially in the same plane, so that when the lever 24 is projecting upwardly the cranks 20 will also project upwardl From this arrangement by moving the ever in an upward direction the bolts 22 will be withdrawn upwardly. The lower edge 3 is beveled, so that it inchnes downwardly toward its outer edge, while the beveled edge 4 is oppositely beveled-that is, it inclines upward y toward its inner edge. When the door is not held in the doorway, it occupies substantially the position shown in Fig. 4. In this connection it should be understood that the door hanging tends to swing outwardly; on the links 12, which support itfrom the an ers, and` this outward swinging movement is imthe sto extenslons 1l of the hangers. With the door anging in this way it may be moved sidewise, the rollers 10 running on the track 8, as will be readily understood. When the door is before the doorway, the bolts 22 lie just above the brackets 13. In closing the door the door is brought into position before the doorwa and the lever 24 is folded downwardly. n doing this the bolts 22 are forced downwardly, and their lower extremities, which are Ieferably beveled, as shown, engage the inc med bottoms 16 of the sockets 15. By forcing the bolts downwardly in this manner the door will be forced bodily upwardly, swinging upwardly upon the links 12. In this way the door is forced upwardly and laterally into the doorway, the lower beveled'edgc of the door sliding up on the beveled sill 3, It should be understood that when the weight of the door is thrown upon the inclined faces ol' the brackcts the door tends to slide toward the car. As it slides inwardly in this way the door will be raised so that it moves upwardly and inwardly in a line substantially parallel with the bevel of the up er and lower edges of the doorway. When tlie door is tightly seated in the doorway, the lever 24 will have come into the position shown in full lines in Fig.V 3, whereupon it may be locked by a padlock. ln opening thel door of course theo eration just described is reversed. When tie lever 24 is held in its uppermost position, as-indicated in Fig. 4, the lower extremities of the bolts 22 will clear the brackets 13, so that no obstruction is offered Vto the sliding of the door away from the doorway.

On account of the manner in which the edges 3 and 4 of the doorway are beveled it is Impossible for rain to leak through the door when it is closed. In this connection 1t should be understood that the edges of the -Patent-- 1. In combination, a car presenting a doorway having beveled u per and lower edges, a door mounted to run lifo'rizontally on said car so as to come before said doorway, brackets having their upper faces inclined downwardly toward the car, and bolts carried by said door and guided thereupon, means for forcing said bolts downwardly to engage said brackets whereby said door may be raised upon said brackets, the inclination of said faces tending to move said door inwardly toward said doorway.

2. In combination, a car having adoorwa with beveled upper and lower` edges, a trac attached to said car, a door having a swinging support on said track and adapted to come into position before said doorwa brackets attached to said ear, bolts slidably carried by said door cooperating with said brackets to raise said door, a lever, means for actuating said bolts by said ets having inclined faces depressed toward the ear whereby said door tends to slide inss'I lever, said brack- Wardly when raised upon said brackets by said bolts.
