Application filed May 2, 1910. Serial No. 558,875.
, To all whom it may concern:
Be it known that l, Fnnnnnioir Caronn- 'Mrminm a citizen of the United States, re-
' well as regular `grain' cars, and which will a effectively prevent the loss of `grain or similar commodities.
Another object of the invention is to provide a 2grain door which is constructed of steel or other metal and adapted to be folded horizontally.
Further objects of the Vinvention are to provide improved means tor mounting, guiding, elevating and supporting the door.
lith the above and other objects `in view, the .invention consists of. the novel construetion, combination and arrangement of parts, hereinafter' fully described and claimed, and 'illustrated in the accompanyin,gg` drawin in which :m
Figure l is an outside View of a portion of a cor equipped with my improved door, the latter being in closed position; F 2 is a View looking at the inner side of the door; F ig. 3 is a view similar to Fig. l but showing the door in partly elevated and folded position; Fig. l is a vertical section taken' on the plane indicated by the line 4-4 in Fig. l; Fig. 5 is a detail section taken on the plane indicated by the line 5-5 in, Fin. 3 and showingin dotted lines the door in -it'seXtrenie elevated and folded position;
Fig. 6 is e horizontal section taken on the plane indicated by the line 66 in Fig. l; Fig. 7 is a detail View of the folding hanger or post; Fig. 8 is a` detail view of one of the door guiding;I members or plates which are arranged on the side of the door opening; Fig. 9 is a detail view of one of the supporting members or plates for holding the door in its elevated and folded position beneath the roof of the car; and Fig. l0 is e detail.viemillustrating the means for fastening; the swinging supports which bold the folded door in elevated position.
Referring more particularly to the drawings l denotes a portion of a railway car or any other structure in which my improved door is used; and E2., 3, el, denote the three sections of my improved door, which latter may be constructed of a `greater or less numbei' of sections which are hingedly united along their longitudinal edges so as to fold over upon inch other and which are. mounted on a swinging suspending device and adapt.- ed to have their end edges engage suitable tguiding` and retaining' members on thc sides of the door opening. The three door sections are constructed of sheet steel or other metal and the lower and upper sections 2, el, are united to the longitudinal edges of the internu'idiate section 3 by means of hinges 5, which latter permit the lower scetion 2 to swing upwardly and inwardly7 and the upper section -1 to swine' downwardly and inwardly as indicated in Fig, 5.
The hanger or post which suspends the door from the upper portion of the ear consists of a` main upper .section G and a folding' lower section 7, the latter being pivoted between spaced ears S on the lower end of the upper section o so that it can swine' upwardly and inwardly but will be prevented, from suvingring outwardly beyond the longitudinal axisof said section (l. The lower extremity ot the folding' section 7 has a. reduced portion or tenen Sl to enter a socketl0` formed in a metallic threshold or sill plate ll which is secured in the bottom of the door opening and has a longitudinal Igroove or channel l2 for the reception of the bottom edge of the lower section 2 of the door. The upper or main section 6 of the hanger has spaced ears 13 which are pivoted between angle brackets 14 secured to a inetallic reinforcing plate 15 which is in turn secured on the inner face of the wall of the car above the center of the door opening, as will be seen on reference to Fig. 2. This pivotal mounting of the hanger enables it to swing downwardly to a perpendicular position' or upwardly to a substantially horizontal position, in which 'latter position the folded door sections are disposed close to the roof of the our, as indicated in dotted lines in Fig. 5.
The several door sections 2, 3,4,are adapted to move longitudinally of the main section 6 of the hanger or post, und to support and guide them I preferably provide on the thereof of the car, whereby the parts of the foldedldooriyill be.more effectively supported. f
1n operation, assuming the door to be in its closedposition as shown in Fig. 1,' when it is desired to remove the grain or `other contents of the car the small door -37 is first opened to permit of the discharge of sulficient .grain to relieve the pressure against the sections 2, 3, 4,"of the door. After this has been done the lockingpawls or dogs 32 are disengagedA from the ribs 28, and the hand lever 24 is then oscillated to rotate the windlass 18 to rwind the cables 19 thereon, and thereby simultaneouslyvmove the three 'sections o'f the door vertically on the hanger or post. As the door is thus moved upl l wardly the guide straps or cleats 31 diseiigage the ribs. 28 so that the upperisection 4 ovthe doorcan swing downwar ly and after the door has been raised to-a predetermined height the bottom edge of the lower section, 2 clears the upper ends4 of` the channeled 'guide flanges 27 of the plates 2G so that said section 2 may swing upwardly and inwardly.
The door section 2 is firstswung upwardly and the' section 4 is then swung ownwardly so that the sections will overlap and- `retain inwardly each other in folded osition, the upper scction 4 bein prefcrab y larger and of greater weight. en the parts are in the position last ymentioned lthe lower section4 7 of the hanger is disenga ed from the socket or seat 10 in the threshol plate and then folded npwardly and engaged with the hook 48, and the hanger 6 is then swungupwa'rdly :in d
tion, and the hook 50 at the top of the car is engaged with the opening Llf) in the section 6 of the post. The supporting members 4,0 are then swung upwardly to engage the endsl i of the folded door sections and are ,fastened bv the catches 47 whereby all parts of the folded door will be effectively retained in elevated position adjacent tothe roof ot the car. By reversing the operation just described 'the door .may be lowered and secured in its closed position.
While the preferredgc,ibodirnents of the invention have been slio` and described in detail, it will be understood thatv I do not wish to be limited to the precise construction set forth, since various changes in the forni,
- roportion and arrangement of parts, and
1n the details of construction may be resorted to within the spirit and scope ot the invention. l
Having thus described the invention, what is claimed is:
l. 4.ln combination with a structure of the class described, having a door opening, a hanger bar pivotally suspended at its upper end, from the structure and comprising an upper section and a lower section, the latter beingf pivotcd to the upper section -and so to a substantially horizontal posi-A engaged at its lower end as to prevent lateral movement thereof, and a door comprising an upper section and lower section pivotally connected together, and foldable one against another, the upper section of the door being slidably mounted on the upper section of the hanger y 2. In combination with a structure of the class described having a door opening, a
