' CARDOOR.

house cars, such as automobile, refrigerator,

furniture and stock cars, being more especially adapted to box cars.

The object of our invention is to provide a door for cars of the class. enumerated, which will be fiush with the car-sides when in closed position; at the same time provid ing a door which will be air-tight and waterproofand so constructed, that when locked and sealed, will be positively burglar-proof because of the impossibility to open the door without first breaking the seal.

A further object'of our invention is to provide a door, especially intended tobe made of steel or metallic plates, which will be simple in design, strong in construction and yet inexpensive to manufacture;:the invention possessing a number of advantages, aside from those enumerated, inherent in the construction and which will be readily apparent, from the following detailed dewherein scription of the accompanyingdrawings,

Fig. 11 isa detail sectional view, taken on the line 1111 of Fig. 1, looking in the 'di form of door-rail and hanger.

In the exemplification of our invention, we have illustrated thedoor composed of a number'of metallic sections 15, shown arranged longitudinally of the door, namely in a horizontal direction; the respective sections having their edges orsicles flanged and preferably presented outwardly so as toprovide the reinforcing orstiifening ribs 16; the flanges of adjacent sections being secured together in any suitable manner as, for" example,'by rivets and the like. I i i rection of the arrows, illustrating a modified The top of the 0100 -1 showni provided with suitable roller-containing hangers 17, the rollers whereofare adapted to ride along or -moveon. the doorscarrying "rail. vThe door-carrying. rail is made in sections, one portionor sectionfto wit section 18,-being pivotally mounted, while the other portion i or section 19 is stationarily secured along the upper side of the car in any wellknown manner, V

The section 18 is pivotally mounted at 20, by means of any suitable hinge or bracket, to the side of the car adjacent toand above the door-opening, as more clearly shown in Fig. 1. This construction permits the free or opposite end of the rail 18 to be moved into and out of alinement with stationary rail 19; the pivotal section of the rail, in Fig. 4:, being shown moved out of alinement, while in Fig. 5 it is shown swung into alinement with rail 19. l j

The bottom of the door is shown provided with suitable guides or'brackets 21 which engage with the door-rail beneath the bottom of the door. This rail, like the doorrail above the door, is composed of a pivoted section 22 suitablyhinged or pivoted at 23 to the side of the car, and a stationary section 24 secured to the car-side; the pivotal section 22 being pivoted so as to permit the free end'to be swung into and out of alinement with the stationarily secured section 24, see Figs. 1 and 6. a

The mechanism for operating the railsection 18, and therefore also the door, comprises a suitable lever 25, which we will term the sealing lever, fixedly secured to the vertically disposed operating rod 26, which is held by means of suitable brackets 27, 27,

more clearly shown in Fig. 6, secured to the side of the car so as to receive the upper and lower ends of rod or'shaft 26, and at the same time permit the latter to rot-ate;

it being understood, of course,that rod 26 is held against vertical movement or displacement.

The door-rails, both at'top and bottom, are preferably made of Z-bars, as more clearly shown in the detail cross-sectional portion shown to the right in Fig. 4 at 19*, although these rails may beeither made of channel iron or angle iron, arranged so as to provide a horizontally disposed flat portion or leg, as, for example, shown in Figs. 11 and 6, respectively.

As the mechanism, whereby the pivoted sections of the door-rails are operatively adapted to extend connected with rod or shaft 26, is identical both at the top and bottom of the door, a description of the mechanism, for example at the lower part of the door, as illustrated in Fig. 6, will suflice.

The mechanism just referred to comprises anarm 28 fixedly secured to the rod 26 so as to be rotated therewith, the opposite end being pivotally secured to the link 29 which, in turn, is pivotally secured to arm 80. The arm 30 is provided witha pin 31 which is into the slot 32 of the pivoted rail section. 5

' It will be noted that the operating mechanism at the upper end of rod 26 is located above the sectional-rail 18, while the mechanism at the lower end of rod 26 is located beneath the sectional-rail 22, so that the pin 31, provided on arm 30, is presented upwardly at the lower part'of the door and presented downwardly in the mechanism above the door. The pin 31 is preferably carried by arm 30 at the end which is pivotally connected to link 29; the opposite end of arm 30 being pivotally connected at 33 to the outer end of the bracket 27.

It is evident from the construction shown and described that the arm 30 will be placed.

under compression, that is, at right angles to the plane of the door when the door is closed, so that any pressure against the door from the inside will be on a dead center with the arm 30 and hence will not have a tendency to operate the mechanism, and therefore will not break the seal of sealing lever 25; arm30 constituting a self-locking mechanism when the door is in closed position.

In Fig. 6 the position of the operating mechanism is shown in full lines in the position it occupies when the sectional-rail has been moved out of alinen'ient with the doorrail 21 and the door moved to closed position; the dotted lines indicating the posi tion of the various parts when the door is moved outwardly, preparatory to being rolled into completeopen position; namely to the position where the free end of sectionalrail 22 is moved into alinement with the stationary sectional-rail 24. When lever 25 is moved to the position shown in dotted lines in Fig. 6, it will rotate shaft or rod 26, thereby swinging the pivotal point 21 of arm 28 to the point shown in dotted lines at 31, thereby carrying pin 31 to the point indicated at 31. The pin 31, extending into slot 32 of rail 22, in its movement through the arc of a circle as indicated in Fig, 6, swings the free end of rail 22 outward and into register with rail 21.

It will be understood, of course, that the rotation of rod or shaft 26 will induce the mechanism at theupper end of the rod to move in a similar manner, and therefore cause the sectional-rail 18, above the door, to also move outwardly and into register with the rail 19. With the sectional-rails 18 and 22, moved to the position indicated in dotted lines in Fig. 6, the door may be rolled along the pivoted sections 18 and and onto the stationary sections 19 and 241.

18 and 22, when the lever 25 may be swung;

back to the position indicated in Fig. 1 and i in full lines in Fig. 6, when the lever will pass over the staple 35, where'it may be sealed in place. The movement of lever 25, as just described, rotates rod 26 and with it the levers, and links previously described, so that the latter assume the position shown in full lines in Fig. 6, which will throw thepivoted' rail-sections out of alinement with the stationarysections and force the doorinto the door-opening in the car-side and therefore flush with the car-sides.

The pivoted rails. are prevented from swinging outwardly too far by means of a suitable bracket 36 secured to the car-side beneath the free end of bottom-rail 22; the

bracket 36 being preferably provided with atransversely disposed slot shown at 37 in F ig. 6, which receives a pin 38 secured to the bottom-rail 22. The top rail may be. provided with similar mechanism, although. the limitation of movement of bottom-rail 22' ,will, of course, by reason of the door-connections to the rails, transmit similar limitation in movement to the upper door railsection 18. This construction and arrangement makes the door absolutely'fool-proof, and at the same timepermits it to be easily operated. 9

In order to provide a weather-proof construction, we prefer toprovide weather-strip 39, see Fig. 5, and the reverse curved flange: 40 at opposite sides of the door, and a weather-strip 41 which is secured to the car-,

side above the door, as shown in Figs. 1 and 3; the bottom of the doorbeing preferably made to overlap the side-sillsof the car, as

can more clearly be seen in Fig. 3, in such a'manner as to prevent moisture from entering the car from that direction.

The top of the door is kept on the pivoted proper operative relation with the. rails.

The bottom of the .door is prevented from jumping 'ofi of the bottom-rail by means of the brackets 21 which are preferably provided with a depending portion or lug adaptedto extend to the rear of-the upwardly presented, portions of the bottom;

rails, as clearly shown in Fig. 3; the relation of the parts just. described beingpb tained by slidingthe door. into POSltlOIl,

namely onto the door-railsbefore the doorstop 43, see Fig. 1, is secured to the side of the car.

We have illustrated main doori pro vided witha small doorl44 in theupper' p artthereof, and a door 45 inlthe lower, part thereof ptheupper smalldoor 44 being used" for the purpose of filling the car, after the main door has been'closed, with such com-v modities as loose grain, coke, charcoal, and

the like; while the lower door 45 is provided for the purpose of enabling the car to be other suitable manner.

emptied, or partially so, of similar commodities before the main door. is movedto open' position. V

The two. small doors 44 and 45 are shown suitably hinged to the main door, so as to swingupwardly,.andare, locked in closed position by means of rod 46 to whichwis pivotally secured a sealing hasp 47, pivotally secured at 48 to the main door- Mounted onthe lower door 45 is a small latch rod or member 49 provided with a spring 50 which maintains a yielding operative relation -be-. tween member 49 and rod 46';.,latch-member 49' being adapted tohave locking engage ment with the bottom frame-portion about door 45; the frame-portion being either pro: vided by flanging the portion of the main door, adjacent theropeningrwhich receives door 45, as shownin Figs. 3 and 9, or in any Byswinging the sealing hasp 47 about its pivotal point 48 so as tov move the free end of the hasp downward, rod 46 will be pushed upwardly and still remain in looking engagement with door: 44. This upward movement of rod 46, however, will permit latchmember 49 to move upwardly throughthe action of spring 50 and therefore out of look ing' engagement with the bottom framemember or door. 45, allowing door 45' to be opened. Movement of the free end of hasp 4 upwardly will depress rod 46 out of locking engagement with door 44, while door 45 may still remain locked.

It is evident from the construction just de-- scribed that both doors 44 and 45 may be independently opened by the movement of hasp 47 in proper direction, as previously described. As the latch-member 49 is carried entirely by door 45 and is separate from the rod46, it is evident that door '45 may be readily opened because the rod 46 will have cleared the door-frame when the latch-member 49 has been raised out of locking position.

It will be ardent m a anemia,

just described that one seal need be employed for securing the hasp 47 onto the staple'5l. secured to the main door, as shown in Fig. l. By sealinghasp-47 both smalldoors 44 and45- will be held locked, and tampering orrobbery of, the car, without breakingthe sealeither of hasp 47 or of the main seal-V ing lever- 25, will be prevented:

In Fig. '11, we show the door-rail above the door madein the naturefof a channel, as canbe seen as l9 the rail section 19? being 52; The hang er 17 4 being substantiahylike hangers 17 previ ouslydescribed, with the. hanger arranged r01 overlap the lower flange: ofthe rail-sectionsl8 and 19?,andtheop- :shown securedin place by a suitable bracket eratingniechanism being similar to thatshown in the other figures, a detailedkle scription thereof neednot be entered into.

We have shown and described what we bearily mounted on the car-side while the other section of each rail above and below the'door-opening is hingedly secured. at one end thereof so as to permit thefree end to swinglaterally and bring it into and out of alinement with the stationarily mounted section, means for slidingly mounting the door on both top and bottom rails, and operating means connected with the pivotally mounted sectionv of both top and bottom rails, said means comprising a rotatable vertically disposed member, a pair of laterally swinging arms pivotally mounted, one adjacent the top and the other at the bottom of the door and adapted to be disposed perpendicular to the plane of the door when the latter is in closed position and thereby automatically lock the door in said position, the free ends of said arms having controlling relation with the free ends of the hinged railsections, said members having controlling relation with said arms.
