STEWART, F KANSAS CITY, MISSOURI, ASSIG-NOR TO THURMAN Il. MCCORMICK, OF JACKSON' COUNTY, MISSOURI :DOOR HANGING AND S1li(TU'llfINGr` MEANS Application filed March 27, 1930. Serial No. 439,420.

rlhis invention relates to improvements in freight car doors and hangers t-herefor.

The primary object of the present invention is to provide an improved freight car door hanger whereby the opening and closing of the door whether it be of single or double type is made easier and may be accomplished without exerting strain upon the door or the hanging elements therefor.

l0 Another object of the invention is to provide an improved type of hangerl whereby double doors may be readily maintained in position in the type of car known as an automobile car, without employing the usual removable center post.

The present device is designed primarily to facilitate the Vconvenient hanging and operations of doors of the flush type where after the door has been moved into position before a door opening the door body is moved directly into the opening so that it will be flush with the wall of the car.V While, of course, as just stated the present hanger structure is designed primarily for use upon the flush type of door it is, of course, to be understood that it may as readily be used upon doors of the non-flush type, that is upon those doors which arenot moved into the door opening after being positioned before the same.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part ofthis specification, with the understanding, however,

that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as suoli changes or modifications mark normaterial departure from the salient features of the invention as expressed in the appended claim.

Figure 9 is a sectional view taken horizon- 65 tally through the lower portion of the nonj flush type of` door showing the means employed for closing` the opening between the rear of the door and the car body. v

Referring' more particularly to the draw- 70 ings wherein like numerals of reference indicate corresponding parts throughout the several views, the description of the present door hanger will be confined first to the construction and application of the saine to a double door structure such as 1s illustrated in Figures l to 3. In these views the numeral l indicates generally a freight car body in one or both sides of which is formed the usual door opening 2 which has at each side a post 3. A pair of doors 4 is employed for closing this door opening 2, these doorsV having their confronting edges each guarded by one flange of an angle bar 5 which eX- 85 tends throughout the length thereof, the other flange of each bar overlying the inner face of the door as shown in Figure 3. The flanges of the bars 8 whichv guard the confronting edges of the doors project forwardlyv ofthe door facesv as sho-wn in Figure 3 and one of these angle bars has secured to its inner flange a plate 6 which projects beyond the adjacent edge of this flange so as to come into overlapping engagement with the adjacent angle bar when the doors are closed thus completely closing the joint between the door edges. These angle bars 5 serve to take the place of the usual center post of double door openings of the character herein shown, 100

these posts usually being removable to facilitate loading of the car with automobiles.

A suitable hasp 7 is pivotally secured to te outer face of one door 4 to extend across the joint between the doors for engagement with a staple 8 carried by and projecting from th-e outer face of `the adjacentJ door.

To the upper central portion of each door body 4 a reinforcing plate 9 is secured which carries a pivotV pinlO to which is attached one end of an elongated door carrying bar 11. As shown in FigureY l Veach .of these main supporting bars 11 is'slotted at its lower end, the slot being indicated by the numeral 12 and there slidably positions in the slot'of each of these bars a pin 13`which'extends into a suitable bearing sleeve 14 in the adjacent post 3.

As shown in Figure 4 these posts 3 are cut away in their outer faces to permit the side edge of the adjacentv door to move into the door opening 2 so that the Vdoor body will be flush rwith the side walll of the car 1.

Theouter side edge of each door 4 has secured thereto a T-bar 15, the central portion 16 of which is attached to the longitudinal edge of theV door while one ear extends over the outer face of the door and the other one projects therefrom and parallel thereto as will be readily understood.. This T-bar upon the outer edge of each door in addition to performing the function of a bumper and preventing the edge ofthe door being damaged, also acts as a cover for the joint between the door and the adjacent body of the car when the door is closed, the last mentioned flange of the bar extendingovcr the adjacent side of the car body asV shown in Figure 3. Any suitable securing means may be employed for maintaining the outer edges of the door bodies in position in the door opening, such for example as the hasp 17 and staple 18.

At a point intermediate its ends, each of the door attached bars 11 has pivotally secured thereto as at 19 one end of a relatively short supporting bar'20. The other end of each of the supporting bars 20 is secured to a pin 21 similar to the pin 13, and this pin 21 is oscillatably and longitudinally shiftably mounted in a sleeve similar to the sleeve 14, in the upper end of the adjacent post 3.

SecuredY to the outer side of the car body directly above the door opening 2 is a hood 22 which has a depending portion 23 to the inner `face of which at the central part of the door opening 2 an abutment 24 is attached which is provided with the oppositely directed inclined faces 25 which face the door opening and which serve to guide the adj acent edges of the door bodies into position inthe door opening 2 when the doors are shoved to closed position.

'As will be readily understood from the foregoing description taken in` association with the drawings, the doors 4 are normally within the door opening 2 and flush with the adjacent side wall of the car body. When the doors are to be moved to open position the hand holds 26 are grasped and the outer or remote edges of the doors are withdrawn from the door opening outwardly to the bracket stops 27 which engage them at their lower edges. YVhen this is done the pins 13 and 2 1V by which the b ars 11 and 20 are pivotally attached to the door posts 3, willv be partially withdrawn from their respective sleeves, each pin, however, remaining engaged in its sleeve. a sufficient amount to permit of its oscillating smoothly therein.

The outer edges of the doors will thus be removed from the door opening while the inner or abutting edges will remain therein in the manner indicated in dotted lines in Figure 2. By then applying a pull to the doors so that eachwill be urged to move longitudinally of and under the hood 22 each door will swing laterally on the linked bars 11 and 20.

The link bar 20 carries the door to which it is attachedthrough the medium of the bar 11 the lower end of the bar .11 moving downwardly on the pin 13 by which is it pivotally connected to the lower end of the adjacent post. Upon shifting the doors 4 in the opposite direction to close them it will be readily seen that the forward edges thereof, coming into Contact with an inclined surface 25 which forms a part of the hood, will be guided into the proper position in the door opening 2 and when the rear edge of each door has arrived at a position opposite the recessed face of the adjacent post 3 it may then be shoved inwardly to final closed position. The pins 13 and 21 which connect the bars 11 and 20 with the post will at the same time move inwardly in their respective sleeves thus permitting the laterally projecting flange of the guard T-bar of the door to come into position against the adjacent outerface of the car wall. The hasps 7 and 17 may then be engaged over their respective staples to secure the doors against being opened by unauthorized persons. K

As previously stated Figure 5 shows the application of the supporting elements 11 and 2() to a single door of a box car, this door here being indicated by the numeral 28. Since the construction and'operation of the links employed for supporting this door are the same as those employed for supporting each of the double doors the same reference characters are used thereon. p

In order to prevent undue outward movement of the door 28 the inner face thereof has secured transversely thereof a guide bar 29 which overlies the lower end of the elongated supporting bar 11 and thus holds it in the proper position` relative to the door. This guide bar also assists. in drawing out the lower end of the supporting bar ll when the door 28 has its free edge removed from the door opening.

The edge of the door opening in which the single door 28 positions, has secured thereto adjacent the post 30 in the recessed face of which the forward edge of the single door moves lwhen shifted to closed position, has a retaining plate 3l secured thereto under which the Vforward edge of the single door engages as shown in Figure 6. This plate 3l overlies the recess formed in the post 3() as shown so that a receiving channel is formed for this edge of the door.

lVhile the same has not been illustrated a cam body is housed in the hood 32 in which the upper edge of the single door 28 moves so that the forward edge of this single door will be guided into position behind the keeper plate 3l as the doors move to closed position, the same as the doors 4 are guided into position by the cam body 24.

In Figures 7, 8 and 9 a slightly modified form of the door hanger is shown for use in connection with car doors of the non-flush type. In these figures the car body is indicated generally by the numeral 33, the door` opening by the numeral 34 and the posts at the sides thereof by the numerals 35. Over the door opening 34 a door hood 36 of the same character as the hoods 22 and 32 is mounted, the hood in Figure 7 being shown in longitudinal section.

At one side of the door opening an abutmentpost 37 is mounted which has a recessed outer face over which extends one edge of a guard plate 38 which is secured to and longitudinally of the outer face of the abutment post. The door body is indicated as a whole by the numerals 39 and as shown in Figures 7 and 9 the rear edge has secured thereto a reinforcing angle plate 40 to which is attached a. cover plate 4l. This cover plate is of a width greater than the thickness of the door and projects inwardly beyond the inner face of the door into close proximity to the adjacent face of the car body so that when the door is moved to closed position this plate acts to cover the opening existing between the door and the adjacent portion of the car body wall. A suitable hasp 42 is pivotally attached to the rear edge of the door as shown and engages over the staple 43 which is carried by the body 33 of the car.

The same long and short supporting bars are used for maintaining this non-flush type of door in position as is used in connection with the other forms. The connections between the bars and one of the posts, however, are different from the other forms for as will be readily seen there is no need for the transverse movement of the connections with respect to the door opening. The bars used for the support of the non-flush type of door are indicated by the numerals 44 and 45. As

stead of being slotted as is the bar l1 previously described, has a pin 46 at the lower endV thereof which is designed to work in the vertically arranged slot 47 of a plate 48 which is secured to the side of the car body 33 adjacent the rear edge of the door and directly before the post 35 at this side of the door opening.

The upper end of the short bar 45 is directly pivotally attached to the adjacent post 35 atits upper end like the short bar 20 of the other forms except, as previously explained, the pivotal connection is not movable transversely of the door opening.

From the foregoing description it will be readily seen that the hanger herein described for the support of a double or. a single car door is of extremely simple design, may be economically manufactured and installed and will operate effectively to support the car door to which it is attached so that it may be easily moved to opened o-r closed position.

Having thus described my invention, what I claim is:

The combination with a sliding door adapted to close a wall opening having an abutment post at one side for engagement with one side of the door, of a carrier comprising an elongated bar upon the inside of the door and having pivotal connection at one end with the central upper portion of the door,

.. a headed pin carried by said bar at its other end, a plate member secured to the outer face of the wall at the side of the opening opposite said abutment post and positioned between the wall and the door and having a vertical slot therein adapted to slidably receive the head end of said pin, a link bar having pivotal connection at one end with said first mentioned bar at a point intermediate the ends of the first bar, and means pivotally connecting the other end of the link bar to the side of the wall between the same and the door and above said plate, said first mentioned bar being designed to swing at its upper end with the movement of the bar and about the pin at its lower end and said link bar supporting the door and the first mentioned bar during such swinging movement.

In testimony whereof I hereunto aliX my signature.

JOHN H. STEWART.
