Application filed `IVlIay 2, 1921. Serialv No. 465,074. y

To all fio/tom t may concern.'

Be it known that I, WILLIAM C. LANG, a citizen of the United States, residing at Superior, in the county of Douglas and Sta-te of Visconsin, have invented certain new and useful Improvements in Grain Doors, of which the following is a specification, ,reference being had therein to the accompanying drawing. i

rlhis invention relates to certain improvements in car doors and has` special reference to what is commonly called a grain door for railroad cars.

The principal object ofthe invention is to provide a door having improvements over what is at present known in the art.

Other objects and advantages of the peculiar construction will appear in the further description of the invention.

ln the accompanying drawing forming part of this application and in which like reference characters indicate like parts:

Figure l is a transverse sectional View through the car door opening fitted with one of the improvedattachments and the grain door partly in place, the covering plate of the door post being removed;

Figure 2 is an outside elevation of the car having my improved door attached thereto:

.Figure vis a vertical sectional view of the uppermost end of a door post illustrating the arrangement of sheaves over which the operating line is reeved:

Figure 4 is a horizontal sectional view through one of the car door posts in which the door engaging operating line reciprocates, and

Figure 5 is a plan view of the operatinghand wheel and its cooperative parts.

l represents the usual door opening in the side of the ear Upon either side of the door opening is installed a vertically disposed, Arectangularly shaped, door post 3. The door post 3 'has formed thereintwo vertical rectangular slots, or cut away portions, the entire length thereof, in either corner adjacent the door opening, as at f d, and which slots may be reinforced by suitable channel irons 5-5 and the metal covering plate 6. I l

Approximately one-third of the distance down from the upper edge of the door and adjacent each side thereof is pivotally attached a suspending chain :24, there being eyefbolts 25l fined to the such attachment.

Members 26, having' eyes therein, are fastened to the under side of the roof of the car from which the chains @ai pivotally depend.' The door being thuspivotally suspended aidjacent its uppermost edge will, when raised by the operating line 27, assume a horizon'd tal elevated position-adjacent the ceiling vof the car as illustrated'in dotted lines in liig-` urel. v f

A short length of pipe 7 is installed in each door post adjacent the uppermost end thereof, the pipe being the 'same length as the width of the door post and pivotally supporting the small'A sheaves 8 8 and the larger sheave 9. Slotted openings are formed in the bottom of the pipe so that the operating line may freely pass therethrough. n

Each operating line is securely fastened door to provide for passes through a suitable hole adjacent the bottom `of the door into the innermost channel 4, up through the slotted openings'and over the sheaves in the pipe 7 and down the other channel l through suitable openings in the floor of the car and isfastened to the operating drum .l2 `fined to the shaft 13 which is rotatably supported beneath the f as at l() to the bottom of the door l1, and

bottom ofthe car by the brackets le and l5.`

The bracket l5 is channelshaped in plan View and supports one end of the shaft 13, ,l

having the beveled gear 16 secured thereto, and the short stub shaft 17, to which is securely fixed the beveled gear 18 `which meshes with the gear 16. An operating wheel'l9 is fixed to the outer endof the shaft 17 and by the rotation of which the door may be readily raised or lowered.

l have shown a wedgeshaped member 20, having a shoulder 21 formed thereon, as attached to the uppermost end of the door post and which is for the purposev of mov# ing the door horizontally, when being raised to its uppermost position, away from the door-post 3 sufficiently so that vthe upper kend of the door will rest in 'the bracket22 rigidly fixed in any desired manner to the f free end of which is lient outwardly and downwardly in spiral iiorm for engagement with the 'aee 'the door as it is raised to adjacent its ultimato uppermost position and by which engagement the free end of' the spring part a door.

Constant downward pressure upon the m ilus is ioi' the purpose of afiording assistance when it is desired to close the door as when the hand wheei 19 is slacltened laway for the purpose oil allowing the door to drop into position the pressure exerted by the springs 23 will impart initial downward motion to the lower edge the door and thus assist in automatic-ally closing saine.

Hai/ing thus described my invention what l claim and desire to secure by Letters Paten* is:

A pivotally suspended door oia the Charactor described for railway cars having a horizontally disposed sha't for operating` saine externally of the ear, lines one end of is iiorced upwardly causing` it 'to ii-neaeh oi which is wound about the shaft and y the opposite. end attached to the door, door posts; each oi' said lines operating in spaced clntnnelsy in the corners oiI their respective door posts.

2. 'lhe combination with a grain door for cars which is closable against the posts of the door opening and slidable vertically against said posts, oi: slots iorined in the two opposite corners oi? eaoh of the posts facing the opening, sheaves mounted at the upper endsv oi the posts, flexible means operative within the slots over the sheaves and attached to the door7 and manually operated shaft loeneath the door externally oi the oar for operating 'the flexible means. l

"En testimony whereof l hereunto ai'iix my signature in the presence of two witnesses.
