DOOR HANGING AND SECURNG MEANS.

Application 'led March 25, 192.1. Serial 110.455,391.

To all whom t may concern.'

' Be it' known that I, JOHN H. STEWART, a citizen of Canada, and a resident of Rutherford, in the county of Bergen and State of New Jersey,.have invented a new and'Improved DoorH'anging and Securing Means, of which the following is a description.

My invention relates to sliding doors for freight cars, and more particularlyl the inivention lrelates to -a freight car doorl adapted to have lateral movement to or from the doorway in addition to its sliding movement, whereby to effect a tight fitting of the door in the doorway. f The invention has for its general object to provide suspension means for the door, whereby. the door ma with facility4 be readquickly and tightly closed, as well as .to provide means coordi nated with the suspension means for fasteningthe door in the closed position.

eference is to be had to the accompanying drawings forming a part of thisfspeci-v vfication, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is an elevation of a portion of a i freight car and the door thereof embodying my invention;

Figure 2-.is a -fragmentary longitudinal vertical section of a freight car giving an inside view of the door and its appurtenances;

`Figure 3 is a horizontal section on the indicated line 3 3, Figure 1;.

Figure 4 is a view inthe plane indicated by the dot-anddash line 4 4,l Figurel, but

, showing the door in the open position as in Figure 2;

'Figure 5 shows the upper portion of the door in side elevation by dotted lines and thecar roof in vertical section by full lines; Figure 6 is a transverse vertical section on the line* 6 6, Figure 3;

Figure 7 is a transverse vertical section on Figure 8 is an'enlarged detail inhorizontal section given to show the lower stop 4bracket and bearing, as hereinafter referred to; f

Figure 9 is an enlarged detail on the line 9 9, Figure 2.

In the illustrated example of my invention thel letter A indicates the door; B, the door f frame; and C, portions of the car body.V The 4numeral 10 indicates a suspension bar of orifice. y

suitable flat material which is pivoted at its l upper end to the doorAv-at the approximate vertical median line thereof at the inner side -of saiddoor as at 11. The lower end of the suspension bar 10 is pivotally connected' as at 12 to a suspension bar 13 preferably betweenthe ends of said bar for reason that will appear. Above the'pivot 12 the suspension 4bar 13 is pivotally secured as by a pin '14.

to'bracket 15' at one side of the doorway on the face of the adjacent `vertical member or jamb. Thus, the bars 10, 13 may have movement on the pivots 11, '12 and 14 with the sliding ofthesdoor A.- 'The'bracket 15 is adapted to swing in a plane transverse to the planev of the' doorway by reason of being pivotally secured at its lower, end as as 16,

the pivot pin 14 being at the upper end of said bracket. swingable bracket 15 has a slot and pin con-l nction with the door frame, there being a transverse slot 17 in said bracket, and a pin l18. passing through said 'slot into the door frame and limiting' the swinging movement of the bracket.` l

The bar- 10 in coaction with the -bar 13 0r'- with that portion of' the bar between the pivots 12 and 14, constitutes a suspension means for the door but I provide the bar 13 lto extend below the pivot 12 a substantial Advantageously, also, thev distance to assist as one means to prevent ythe v turning of the door in its own plane with the pivot l11 as a center, the lower end of thebar 13 having' a transverse pin 1 9 having lmovement'in a vertical slot 2O in a gulde bracket 21'suitab1y secured to the inner face of the doorjA as bv rivets 22, the broad head 19El of the pin 19 'being housed within saidy bracket' 21 for preventing displacement of the pin. Gruide'means for the door is prosliding movement of the door to or from the closed position. The weight of the doorV is sustained by the bars-10, 13 not by brackets 23, 24 and the guide rail v 25. The rail 25 1s U-shaped in cross section,being upturnedat lvided `also in the form of brackets 23, 24

-with 'the brackets- 23, 24 fory the complete i the inner sid@ clearly shown 1n lrigures.`

6 and 7 and the upper ends of the brackets 23, 24 are turned outwardly and downwardly giving them a hook format the up- Y per ends, the reverse of said U-shaped rail 25. The bracket 23 engages the rail 25 at all times both in the closed and open positions of' the door but the bracket 24 is adapted when the door is at the doorway B tomove toward or from the doorway and into and out of engagement with the guide rail 25. For the movement of the bracket 24 into and out of engagement with the guide rail 25, the vlatter is formed inits up- `turned portion with acut-out 26 aording clearance for the hooked end of bracket 24 to move laterally relatively to said guide rail with the movement of the door transversely to the plane ofthe doorway. stop bracket 27 is provided on the body C at the bottom adjacent to thatside of the door frame having the swinging bracket 15.

The door A, it will be observed, when in the closed position, lies in a plane outside of \the pivotal connection 14 between the suspension element 13 and the car body and thereby .the door has a tendenc to move outwardly from the opening under its own weight.. I provide means for effecting the tight closure of the door A., and for fastening the door in the closed position of Figure 3, said means consisting of a vertical rod 30 adapted to turn at its upper. and lower ends respectively in bearings 28, 29 on the car body to permit said rod to turn through 180.- On the rod 30 are lateral fastener arms 31, 32 .near the topand' bottom of the rod respectively the lower arm 32 being longer and constituting a hasp to permit the( arm to pass over a staple 33 on the door A' adapted to receive a padlock. The arrangement of the lock rod with its arms is such that if the door A in the closing movement thereof arrives adjacent to the doorway, but not quite in register therewith,

. the arm 32 is grasped to turn the rod 30 on its axis and cause `said arm 32to be pressed against the door at the adjacent edge whereby the door will be forced to move both in its own plane and laterally inward to the plane of the'doorway. The rod 3Qiis halfround and when -in position with the arms 31, 32, away from the door, said rod is accommodated in a concave vertical recess c in the carfsiding adjacent to the door frame B and as indicated in Figures 3 and 4.

At the' opposite side of the doorway from thelocking rod 30 keeper plat'es34 are secured to the car to project beyond the door frame, whereby the adjacent edge of the door may be slid beneath said keepers when the door is moved to position at the doorway under pressure of the arm 32.

A keeper 35 is provided on the side of the car body to engage that edge ofthe door farthest from the door opening when the about the pivot 14, by the track 25 and its supporting means, andsince at the bottom there is a Aslot and pin connection between the door and the element 13"byreason of the pivot 19 sliding in the guide slot 20, which is directly in alinement with the pivot point 11, the door is constrained to move in a straight line without rising orfalling moven l ment.

It will be observed also that by the suspension means described I am enabledto dispose the suspension means at the 1ns1de of the door, notwithstanding the limitations l as to space determined by the unalterable positions of the frame beams of the car body above and below the door opening, the result bein attained by reason of the suspension e ements being arranged toA impart direct rectilineal movement to the door and by the fact that the pivotal connection at 14 is at the door opening below that car beam which is positioned above thedoor. Therefore, the suspension means is accommodated between the upper and lower longitudinal frame beams and therefore maybe mounted close to the door in a plane para-llel with the door.

I would state in conclusion that while the illustrated examples constitute practical embodiments of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without (de-V parture` from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim:
