' Our invention relates to slidingdoors such as are used on freight carsof the box type,

and on warehouses and Other stationary structures, and is more particularly con- '5 cerned with a mounting for such doors embodying structural features facilitating their operation and maintenance. 7 r I A feature of our invention Consists in the provisionof a sliding mount for such doors constructed to exclude water ands'now from the door supports to prevent 'cloggin of the slide ways with ice and snow, whic with constructions in present use iseifective to prevent the opening of" such doors in cold weather. r

Another feature of the invention consists in the provision of amounting, housing the edge of the door and preventing the entrance of water, sleet and snow to freezeand inter:

fere with the opening or closing ofthe door 7 Further features of the invention consist I in the provision of adjustable door supports of novel construction, and in the. structural combinations and arrangements hereinafter A preferable embodlment of the: invention forming part hereof and in which} Figure 1 isa view inelevation of our improved sliding door mounting asfapplied to a railway freight car.

is illustrated in the accompanying drawings Figure 2 is a horizontal section on the line 2-2 of Figure 1.

of the upper roller housing modified for attachment to the top of steel railway cars.

Figure 7 is a perspective detail of the door hasp in latched and sealed position.

The sliding door 1 is supported by hangers secured to the face of the door adjacent to its top and bottom edges, and having offset arms extending in the plane of the door and enures'3 and 4; of the drawings Figure 3 is a vertical section on an enlarged tering into slots formed in the bottom ofthe door hanger housings. These housings, as seen in Figures 3 and 4, are closed at the sides and'top so that snow andwater may i not enter therein to clog the door. The top housing 2 and vthe'bottom housing 3 are of the same construction, and one,only, need be described in detail. Referring particularly tothetop hanger housing and to Fig- The housings are formed of complemental metal-"sections 4 and 5 which extend longitudinally of the door casing adjacent to the top and bottom edges of the door. The inner section 4, as shown, comprises a flat vertically extending plate 6xbent outwardly at itslower end to'form a longitudinally extending track or channel 7 edged by 'a retaining flange 8. The outer sections 5 ofthe hanger housings are formed with an upper vertical flange 9 abutting the upper portion of the plate 6 of the inner section from which extends an outwardlyoffset top or :cover portion 10 terminatingiin a vertically downward I lower or base portion 11 substantially spaced I from the opposite portion of the plate 6 and, a similarly to'the plate 6, is provided with on inturnedlower edge forming a complee mental roller track I or channel 12 inwardly edged by aroller retaining flange 13. These two sections are rigidlyjoined together by means ofbolts 14: extending'through their abutting upper portions and through theadjacent casingof thedoorj The edge flanges 8 and 13 are spaced apart and in parallel, providingan entrance slot'extending' longitudinally of the bottom of thelhanger housing through which the door carried hanger armextends. f

Preferably, and as is customary, atleast 9 two hangers arejfprovided for both the top and bottom of the door. These hangers, as employed at the top of the door, are in the form of brackets 15 having their bases engaging the outer-face of thecdoor and rigidly fixed thereto by a plurality of bolts 16 extending through the door. At the'upper end of their bases, they iare'provided with 'ofi'sets l7 overlying the top edge oftlie door and further extended to providea hanger arm 18 extending vertically in the central plane of the door through the housing slot. The upper end of the hanger arm 18 extends above the upper edge of the wheel retaining flanges 8 and 13, and carries a suitable axle 19 upon which supporting rollers 20 are journalled. The specific mounting of the axle and rollers is immaterial, and any standard construction may be used. These rollers rest upon the tracks 7 and 12 and are retained therein by the edge flanges 8 and 13 so that in sliding the door, the rollers ride longitudinally in these tracks and support the door from the housing 2. c

The hanger bracket at the lower edge of the door is advantageously made for adjustment vertically of the door so that proper distribution of supporting strain upon the top and bottom hanger housing may be effected. The brackets embodying the bottom hangers are formed with two sections; a base section 21 rigidly and permanently bolted to the door 1 at its lower edge, and ahanger section 22 adj ustably supported from the base plate of the section 21. This is effected by providing these plates with stepped interfitting engaging surfaces extending vertically of the door with means for. effecting vertical adjustment of the hanger section upon the fixed section 21. These stepped Surfaces are conveniently formed by providing the base plate 21 and upper arm 23 of the hanger with laterally extending corrugations 24 providing alternating projections and depressions which interfit one with the other and afford a verysubstantial degree of support for the hanger 22. Adjustment is provided by pairs of vertically alined bolts 25 extending throughthe door and through alined openings in the base plate 21, the upper arm 23 of the hanger being provided with elongated slots 26 registering with these bolts, and of a sufficient length to permit the maximum degree of adjustment which may be necessary in fitting the door. The ends of these bolts projecting through the slots 26 are obviously engaged by washers and nuts to clamp the interfitting base and arm 23 in the desired position of adjustment vertically of the door.

The lower hangers at the lower extremities of their arms 23 are offset outwardly at 27 and thence extend downwardly parallel with the face of the door, their lower ends terminating in inward ofisets 28 having upstanding vertically therefrom, hanger arms 29 ahned wlth and extending through the central longitudinal slot in the bottom of the bottom housing 3. The bottom hanger arms 29, similarly to the upper hanger arms 18, mount axles 30 upon which rollers 31 are journalled. Also as in the case of the upper housing, the arm 29 extends above the edge flanges 8 and 13 with the rollers 31 resting upon the tracks 7 and 12. It will be evident that in mounting the door, proper distribution of support to the upper and lower housings is facilitated by providing for adjustment of the bottom hangers. Preferably, the top and bottom hangers are alined so that the adjustment of the bottom hangers may have the effect also of equalizing the support between the respective pairs of hangers.

Sliding doors, upon the exterior of buildings, freight cars, etc., are often diflicult to open or close in winter weather because of the formation of ice between the edge of the door and the door casing, due to the penetration of rain, sleet and snow between the door edge and easing. In conjunction with the door hanger housings, we have provided door end housings secured to the sides of the door casing and cooperating with the hanger housings to protect the door from the entry of rain, sleet or snow, as described. These housings are in the form of metal plates 32 having edge flanges 33 adapted to rest against and be bolted tothe face'of the door casing or car side,;and extending. vertically of the casing to a pointbeyond the top and bottom edges of the door. Within the boundaries of these edges, the plates 32 are flangedto provide channels 34 to receive and house the edges of the door in open or closed position, the edge flanges 33'being extending beyond the top and bottom edges of the channel or door edge housing 34 and having lateral olfsets 35 extending in the. direction of the adjacent' hanger housings 2 and 3. These housings are of a length to extend over and cover the open tops and bottoms of the channels 34 with the extensions 35 of the door edge housings overlapping andbolted to the ends of the topflanges 9 of the outer section of the hanger housings, as shown in Figure 1 of the drawings, andas suggested by the separated view of these parts inFigure 4. Since the hanger housings 2 and 3 are closed at their. sides and top over and under lie, respectively, the upper and lower ends of the channels 34, the entry of rain, sleet or snow in these channels is prevented,-so that with door closed or fully opened and the door edge fitted in the housings, it will now be impossible for rain, sleet or snow to enter in their channels to freeze the door shut or open as the case may be.

The hanger housings 2 and 3 and the end housing 32 therefore provide a continuous housing around the edge of the door casing cooperating with and protecting it from the dangers of cold weather freezing and clogging.

1 The sliding door may be attached in its closed position for sealing by means of a bracket 36 which may be fixed to the door casing by bolting or riveting to the channels 34 of an edge housing 32, the bracket bein formed with an outstanding keeper plate 3 'lllO having its edge notched to form a T slot 38 therein. Upon the face of the door is secured a hasp mount comprising a plate 39 bolted or screwed to the face of the door and loosely pivoting thereon at 40, a hasp 41 having an H head 42, the cross bar 43 of which is adapted to enter the T slot of the hasp through the standard or stem slot portion 44 in the vertical edge of the hasp. One leg of the H head and an adjacent portion'of the hasp may be drilled as indicated to receive the Wire or metal ribbon of a seal when the door is that of a freight car. The hasp 42 maybe pivotally mounted upon the plate 39 by means of a pivot hook 45 inserted through an opening in the plate 39 at the pivot point of the hasp and entering into the door-1, the 7 shank 46 of the pivot hook being rigidly held by means of a clamping plate 47 bolted .2 through the underlying plate'39'tothe door V 1 and clamping this shank between-itself and the base plate 39. V

The hanger and door edge housings described are applicable generally to building structures and to wooden freight cars. In

applying the hanger housing at the top of the 7 door to steel freight cars, the top housing 2 is slightly modified as shown in Figure 6 of the drawings. The inner section 4 having the upper end of its plate portion bent down wardly as at 48 and the upper end of the outer section being correspondingly made horizontal as at 49 so that a horizontal inner edge of flange is presented, which may be bolted to the top edge of the steel car.

The illustrated and described structural embodiments of the invention, while taking a preferred form, are intended as illustrative, rather than restrictive of the invention, and

- 4 it is to be understood that structural changes and adaptations may be permissible in con sonance with the spirit of the invention and the scope of the appended claim.

What we claim, therefore, and desire to secure Letters Patent is: r I

In a door hanger, a supporting structure having an opening and sliding door, 'atubu lar housing mounted beneath said door, said housing having a longitudinal slot in the I 50 underside thereof forming parallel track- .ways, hanger brackets securedto the front face of said door, said brackets depending from said door and having an ofiset hanger arm disposed in said slot, and rollers journalled on said hanger arms adapted to trav- I erse said trackways upon sliding'movement of said door. 1 Signed at Atchison in the county of Atchison and State of Kansas, this 14th day of January A. D. 1928.
