The brackets 50 32 and 35 are similar to hanger or bracket 26 and all are shown pivotally mounted on thevup per portion of door hanger ZI in a similar man ner, as for example by means of the blocks 28, see Figure 2. ‹ hearing 65 2 8,132,817 The ?anged rollers 25 are adapted to ride along the upstanding ?ange 24 of the track forming member 23; and the roller carrying brackets 26, 32 and 35 are mounted to swing or move through vertically disposed arcs for pur poses hereinafter described; the bracket or hanger 26 being Suspended by means of the bolt 21; the bracket or hanger 32 being pivotalLv supported _by a bolt 31., while the bracket or 10 hanger 35 is pivotally Suspended by means of to the left in the sector plate 43, which looks the door in closed position. Upon releasing latch-pin 45, hand lever 42 may be swung toward the right. This causes the roller carrying journal 39 to ride downwardly in the horizontally disposed arcuate slot 40 and toward the vertical plane of the _pivot point 21 of the lever. such movement, also causes the roller carrying bracket or hanger 26 to swing somewhat toward the vertical plane and induce 10 ` bolt 38; the bolts 31 and 36, like bolt 21, being a pressing action of the roller 25 on the track held in place by the bearing blocks 20,'which . way 24, which forces the door' 20 upwardly out of close bearing relation with the threshold rail in turn are secured to the overhead portion of ,46 and moves the weather strip 49, which is the housing member 2l. . secured to the bottom of the door, out of frie The rollers 25 are joumalled in the respec 15 tive hangers 26, 32 and 35 by means of 'suitable tional contact with the threshold and allows bolts as at 39, see Figure 5, and these bolts pass the door to slide freely into open position. As the roller carrying brackets 26, 32 and 35 through the respective hangers and through suitable arcuate slots 40 in the side wall of the are connected together by means of the con« 20 necting links or bars 30 and 33 and as each 20 housing element, see Figure 1. The ?anged roll ers 25 are preferably provided with roller or roller journal or bolt extends through a similar ball bearings as at 4l, see Figures 2 and 5, to arcuate _slot 40 (see Figure 1), it is apparent that each roller carrier or bracket is correspond ensure easy operation. The slots 40rin the housing element 2l are ingly oscillated and consequently the' entire door made arcuate as shown in Figure l, to permit is raised ? to a similar extent throughout its the respective bolts and the roller-carrying length and its sliding movement readily acco?n brackets or hangers 26, 32 and 35 to swing or -plished. In operation, the operator, having shifted lever move through vertical arcs and permit the roll 42 as mentioned, releases the trigger in order ers to assume different positions relative to the that the, lever may be locked in that position 30 30 bracket supporting bolts 21, 31 _and 30. The bracket supporting bolt 21, at what may and the lever 42› may be then also used for be termed the front end of the door, extends pulling the door to either open or closed position. Swinging lever 42 further to the right in Fig through the side of the housing element 2l suf nciently to provide pivotal support for a hand ure 1 not only raises the door with its weather strip oil' the threshold 48, but causes the top 35 lever 42 shown in Figures 1, 4 and partially in Figure 5. The lever depends from bolt 21 on edge of the door to be brought into close or im the inside of the door rearward of a sector plate pinging relation with the bottom of the track 43 secured on the inside of the door as shown rail 23. The upper edge of the door 20 is pref in Figure 1.

As previously stated and as shown in Figure 7, somewhat greater than the distance between the pivot pins or bolts 21, 31 and 33 and the track the car ?oor at the door opening is provided with a suitable strip 40 having a longitudinal 80 60 ?ange 24, thus necessitating the roller carrying upstanding rib, somewhat of inverted U-shape hangers 26, 32 and 35 tobe mounted at an in clination relative to the vertical plane of their cross-section except that the side disposed to pivot points 21, 31 and 38 so that the lower ward the car exterior is made to slope down roller carrying ends are disposed toward the for? wardly outward while the side of the inverted V-shape rib disposed toward the car interier is 65 ward end of the door, as clearly_ shown in Fig 65 ure 2. When the rollers are in the position preferably substantially straight, as shown in shown in this ?gure, the door 20 will be lowered Figure 7. This strip extends throughout the door into contact with a threshold rail or member opening and is securely fastened to the car-floor '48 shown in cross section in Figure '1, and later and also constitutes a guide rail for the door. The bottom of the door 20 is grooved correspond 70 70 described. ingly and the door preferably is provided with a The mechanism as illustrated in Figure 1_ reenforcing plate 5! having ?ange portionscon namely with the hand lever 42 swung to its forming with the groove as shown at 52, see Fig extreme left position-shows the door in com ures 6 and 7, in order to prevent wear of the plete closed position and with the spring con trolled latch-pin 45 in register with the notch groove in the wood door; the bottom outer edge' 75 y ~ 3 2,132,817 of the door beyond the groove is shown provided with the weather or rubber strip 49, seeFigures `6and 7. ` With the rubber strip 49 in addition to the moisture shedding slope of the rib in the thresh old element 48 and the correlatedg'roove 'in the bottom of] the door, a weather proof condition at the bottom of _the “door is provided especially when the latter is closed and in its lowered con dition', namely a condition. obtained when lever proof condition at the bottom of, the door also effected. , ›. .i e , _ When the door has beenmoved to complete closed position, lever' 42 will be in the extreme left hand position, shown in Figure 1, with the 5 connected roller carryingbrackets 26, 32 and 35 oscillated to the left as shown in Figure 2.

With the wedge block` 54 heretofore described and the engaging elements 56, 51, it is evident that when the door is moved to closed position, In certain instancesit may be found su?icient 45 merely to employ two roller carrying brackets, namely one adjacent the forward end and the other adjacent the rear end of the door. In such cases, the intermediate roller carrying bracket 32 is ornitted as well as the double clevis 3| and the connecting link or bar 30 then made longer 50 and pivotally connected to the rear bracket.
