Specification of Letters Patent.

Patented Dec. 5, 1916.

Application led February 17, 1916. Serial No. 78,861.

To all whom t may concern Be it known that I, THOMAS R. B RUM- BACK, a citizen of the` United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Fasteners for Grain-Doors, of which the following is a specification, reference being had to the accompanying drawing.

My invention relates to improvements in fasteners for grain doors, the objects of which are, to provide a freight car door, in which all of the elements required for use in a grain door, such as a relief door and upper doors, shall be so combined andoperated, that they can be simultaneously locked, and to provide locking devices whereby all of said doors, including the car door, are instantly locked.

Further objects are, to so construct said locking devices, that the same can be sealed by the use of one ordinary car door seal.

I attain the objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is an outer side elevation of the car door and a portion of a car. Fig. 2 is a horizontal section on the line V V, seen in Fig. 1, looking downward. Fig. 3 is a horizontal section of the relief door, on the line 1V lW, seen in Fig. 1, looking downward. Fig. l is an enlarged vertical section on the line X X, of the locking bolt in detail, seen in Fig. 6, looking toward the left. Fig. 5 is an enlarged horizontal section in detail, cut through the center of the outer end por tion of the locking bolt, looking downward. Fig. 6 is a transverse section, on the line Y Y, seen in Fig. 1, looking toward the left. Fig. 7 is a side elevation of the inner side of the door and of a part of a car. Fig. 8 is an enlarged front elevation of the relief door lifting means, showing the parts released for lifting. Fig. 9 is a transverse section on the line Z Z, seen in Fig. 1, looking toward the left.

Referring to Fig. 6, car door 1 is slidably guided by rails 2 and 2', which are formed with plates 3 and 3', respectively. The top surface of plate 3 is set flush with the upper surface of floor 3, while plate 3 is secured to the bottom surface of cap sill 4. Transporting wheels 5 rest on rail 2 and are rotatably mounted in said car door for trans- `Ursel wheels 5 'are similarly mounted in the upper edge portion of said door for preventing lateral tilting or cramping of the corners of the door. Rack 6 is secured on thelower portion of said door, said rack having its vided with latch 10, which is adapted to engage the teeth of said ratchet plate, for detachably holding said door 1 in closed position. Said latch is provided with latch handle 10, for disengaging it from said engagement. Said parts are protected from 2 mechanical injury and from the elements by ratchet shield 8, seen best in Fig. 1.

Car door 1 has a grain opening 11 formed through its lower portion, which is controlled by relief door 11, which is mounted for vertical, slidable movement in said car door. The lower end of'relief door rack 1Ql is secured on the upper surface of relief door 11; said rack being in engagement with pinion 13; said pinion having hubs 13 formed therewith, which are rotatably mounted in car door 1. Square socket 13" is formed through the outer one of said hubs, and through said pinion, for forming a socket the inner end of which is closed. Said socket is adapted to receive the square end of any ordinary square shanked socket wrench, (not shown,) which may be formed in any suitable manner for rotating pinion 13. Upper doors 15 and 16 are slidably guided forhorizontal movement in countersink 1 formed by a paneled portion of car door 1, seen in Fig. 7. Said countersunk panel has an upper opening 1, formed therethrough, which is controlled primarily by said upper doors. Said opening is of such 'size as will readily permit passage therethrough of the person of a carinspector, manually handled grain or other freight, and passage therethrough of a pneumatic grain tube, not shown. Door 16 has latch hook 17 pivotally connected with its inner edge portion; said hook being engaged .with the adjacent edge portion of door 15. Said hook has seal strap slot formed through its free end portion, said slot being adapted to have the strap of an.

ordinary car seal, (not shown,) passed therethrough. Door 16 is stopped at the limit of its inward movement, by stop 16, indicated by dotted lines in Fig. 1. Said hook 17 is adapted to be rotated clockwise, through inortises 16 formed through doors 15 and 16, for releasing the doors.

Referring to Figs. 7 and 9, shield door 1S is slidably mounted for vertical movement, in the inner, upper portion of car door'1. Said shield door is frictionally held at any desired height, for preventing outflow of grain, when doors 15 and 16 are open.

Referring to Fig. 1, wooden boards 1S are secured on the paneled surfaces of Ydoors 15 and 16, and on the side 9, of the car, for holding cards, (not shown,) tacked thereon, for carding the car in the usual manner.

Referring' to Figs. 6 and 5, cardoor 1v is provided with lock bolt 19, which is actuated to move inwardby spring 2O.V Said springand the outer portion of said bolt are housed in housing 21, which has weather shield 21 formed therewith seen in Fig. 1. Seal strap slot 21 is formed through the outer end of said housing, while another seal strap slot 22, is formed through the outer end portion of bolt 19, in register with the slot 21, for reception through both of said slots, of the strap of an ordinary carV seal, not shown. The inner end of said bolt has sloped face 19 formed thereon, and has spline 19 formed therewith, which is passed through aperture 21, formed through the inner end of said housing, for holding said bolt against rotation. Sloped face 19 of bolt 19, is adapted to lift the free end of L crank 23, when said bolt is slid inward, and to allow said free end of said L crank to gravitate, when said bolt is manually moved outward. Said L crank is pivotally mounted in car door 1, and has its upper end pivotally connected with the right end of connecting rod 211, the intermediate portion of said rod being pivotally connected with the lower end of crank 26, which latter terminates at its lower end in forming the depending lock bar 25. The intermediate portion of crank 26 is pivotally mounted in car door 1, while its free end engages door 16, for lockingV saidY door in closed position. Door 15 is similarly locked by the free end of lock crank 27, which is L shapedv and has its lower end pivotally connected with the left end ofV connecting rod 24. The lower end of lock bar 25 engages the upper portion 14 of one of the guides 14, for locking relief door 11 in closed position, and is adapted to be swung therefrom, to the position seen in Fig. 8, for unlocking said relief door.

Referring to Figs. 1 and 2, door 1 has channel 28 formed throughout the left edge thereof; said channel being engagedrwith tongued door .casing 29, for forming a,

weather and grain proof joint. Said car door has the double flanged strip 30, formed therewith, the inner edge of which engages the flanged edge of post 31, while the outer flanged edge 'of said strip engages the flanged edge of door casing 32, for forming grain proof and element proof joints respectively. Posts 31, 33 and 34 have the preferably sheet metal panel 35, secured thereon,

and wooden car lining 36 secured thereon against said panel. The space between said panel and the side 9, of the car forms a door pocket 37, into which car door 1 is slid when opened. The right end of said pocket is closed by lining piece 3S. Said pocket is provided with clean-out doors 39, and since said doors may be of any suitable kind for closing an opening, the same are neither fully'shown'nor fully described. Y

In operation, with the parts in the position seen in Figs. 1 and 6; the car door sealer passes the strap of an Yordinary car door seal, (not shown,) through slots 21 and 22, (see Fig. 5,) thereby sealingvthe hereinbefore described locking means. The thus sealed car Vis manually opened by the operator,'who draws bolt 19 outward, (sec Figs. 5 and 6,) which at the beginning of its movement, shear-cuts said seal strap, thus unsealing said car door. The operator c ontinues to draw said bolt, (overcoming spring 20,) until spline 19" haspassed outward through they inner end of housing 21. He then rotates said bolt until said spline is out of register from spline slot 21, (see Fig. 1,) and releases said bolt, which is thereby detachablyV held in itsV outward position. When saidl bolt is thus drawn, the free end of L crank 23 gravitates and rests on the bottom of slot 23. This movement of said L crank, moves rod 241, (see Fig.V 1,) toward the right, which movement is conveyed to the lower portions of lock cranks 26 and 27, thereby moving their free ends downward, from engagement with doors 15 and 16, unlocking said doors. This movement of crank 26, swings lock bar 25, from the position indicated in Fig. 1, to theposition seen in Fig. 8, thus unlocking relief door 11. Vhile the partsin the described position, any or all of the described Vdoors may be independently opened, as desired. If the car be loaded with grain, ready for an inspector to take samples therefrom, said inspector unhookg hook 17, (see Fig. 1,) slides doors 15 and 16 from each other, and enters and leaves the car through the opening thus disclosed. 1f the car is to be emptied of grain, or of any other substance that will readily flow, such as gravel, nut coal and the like, the beforementioned socket wrench is inserted in socket 13, and pinion 13 is therebyv rotated clock-wise. This rotation lifts the therewith engaged rack 12, which lifts relief 1109x7711, thereby rermttingaqwof said substance, through the lower opening through car door l. After the pressure of said substance is thus removed from said car door, said operator removes said wrench, after which said relief door gravitates to the position shown. Said operator then releases latch 10 from its ratchet engagement and rotates handle 10 clock-wise. This rotates pinion 7, which draws rack 6 and the therewith connected door l, toward the right, thus opening said car door. Shield door 18 is slid to such height as the height of grain or other substance may determine for preventing outflow of same, when said upper doors are opened, as previously described7 and is lowered to the limit of its downward movement, when freight is manually passed through opening l, seen in Fig. 2. Should fine dust or other extra fine sediment, accumulate on the bottom of door pocket 37, doors 39 are opened, and said dust is removed therethrough.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent; is

l. The combination with a freight car door having a plurality of smaller doors movably mounted therein and also having door holding means for detachably holding said smaller doors in closed position; of a bolt housing secured on the outer side of said freight car adjacent to the rear edge of said car door said housing having seal strap slots formed through the outer end portion thereof; a bolt slidably and rotatably mounted in said housing said bolt having another seal strap slot formed therethrough said other slot being adapted to be moved from and into register with the first mentioned slots positioned therebetween; a spring in said housing whereby said bolt is moved inward projecting the inner end portion of said bolt behind said rear edge of said car door for locking the same in closed position; bolt holding means whereby said bolt is detachably held in its outward position against the action of said spring said bolt holding means being released by rotation of said bolt; and moving means operated by the inner end of said bolt whereby all of said door holding means are simultaneously moved into operative position when said bolt is moved inward; the whole forming spring actuated sealable locking means whereby all of said doors are simultaneously locked.

2. The combination with a freight car door having a plurality of smaller doors movably mounted therein and having door holding means therein for detachably holding said smaller doors in closed position; of bolt mounting means secured on the outer side of said car adjacent to the rear edge of said car door; a bolt slidably mounted in said mounting means; a spring for actuating said bolt to move inward projecting the inner end portion of said bolt behind the rear edge of said car door; moving means actuated, by the inner end portion of said bolt for moving all of said door holding means into operative position when said bolt is moved inward said door holding means being adapted to be reversely moved by gravitation thereof when said bolt is moved outward; and'car sealing means formed in said bolt and said mounting means for the recption of the strap of an ordinary car sea 3. The combination with a movably mounted freight car door; of a bolt housing secured on the outer side of said freight car adjacent to the rear edge of said door said housing having a bifurcated outer end portion formed therewith and seal strap slots formed through said bifurcations said housing also having an aperture formed through its inner end said aperture being adapted to loosely lit around a splined bolt; a lock bolt slidably and rotatably mounted in said housing; a spline formed on the inner end portion of said bolt; a spring in said housing for at all times actuating said bolt to move inward said bolt having a seal strap slot formed through its outer end portion adapted to be brought into register with the rst mentioned slots by said movement; and shielding means for shielding said slots from the action of the elements.

In testimony whereof I affix my signature in the presence of two witnesses.
