Applicants novel dust-proofing arrangement and weather seal is shown utilized with the type of liftdoor illustrated in Figures 1, Zand 3 of the drawings. 'I'he d'ooil illustrated vis designated by the numeral I0 and comprises preferably a sheet metal panelII which may be pro- -merging at their ends with vertical corrugations I3 and Il. A reinforcing marginal frame is secured to the metallic panel II and embodies anl upperreinforcing member I5, disposed with one vided with spaced horizontal corrugations I.2

leg I6 thereof extending inwardly horizontally 3 toward 'the railway car I'I upon which the door is mounted. The reinforcing frame, additionally, includes a front vertical substantiallyV channel v 4shaped reinforcing member I8, a rear'vertiCal reinforcing member I9 and al lower horizontal 5y reinforcing anglemember'ZIl.

As hereinbefore stated the door is preferably of the lifttype whereby, in its closed and lowered` position, saido door is adapted to have frictional engagement with a supporting track 2| 10 secured by means of a plurality of brackets 22 to the side sill reinforcing member 23 of 'the car. Frictional engagement for the door is effected through the medium of the lower reinrfforcing. angle member 2li, as best shown in Fig- 15 lure?, of the drawings.

door the frictional engagement is broken and the In order to move the door supported upon a plurality of rollers 2lV constituting a portion of an elevating mechanism designated as a whole by the reference numeral 2o Referrmgto Figure 2 of the drawmgs it will be apparent that the forward movement of the door is terminated by the front vstopv member 26,`

/ which is secured to the front door post 21. At 25 the rear of the door a sealingl strip 28 is secured tothe inner face of the door and adaptedfto engage a spark strip 29 secured to the rear door postl 30. The construction at the top of the door is clearly illustrated in Figurel 3 of the drawings 3o and embodies a Z shaped side plate 3|, to the depending leg 33 of Awhich a substantially Z shaped retainer 34 for the top ofthe door is secured. The depending leg 33 additionally car'- ries an angle member 35 disposed with its hori- 35 zontal leg 36 extending outwardly so as toV be overlapped by the inwardly extending leg I3 and 'the angle member I5 secured to the upper margin of the door. For the purpose of providing a permanent and 40 eicient dust seal for the -doo I0 it is preferred to utilize a nonmetallic tubular flexible sealing strip. In the closed positionof the door the forward edge thereof is adapted to engage the sealing strip 31 secured to thefront stop 26 in e145 manner hereinafter indicated.v Atv the rear vertical margin of the door the strip 28 carried by the'door is adapted to engage a similar flexible 'tubular sealing strip 38 fastened to the spark strip 29.- A similar flexible sealing 5o strip 39. is secured.. upon the outwardly extending leg 36 of the angle member 35, whereby'the inwardly directed leg I6 of the door Ireinforcing angle I5 is adapted to bear-upon and-provide anj eective 4weather and dust seal for the-upper 55 portion of the door when said door'is in its closed and lowered position. 'I'he lower portion of the door is rendered weather and dust-proof by means of a flexible sealing strip 40 secured between the opposed faces of a threshold plate 4I and the horizontal leg 42 of an angle member 43 rivetedto the .upstanding leg of a. side sill 44.

In order to rapidly and eflciently fasten the tubular sealing strips to their supporting members applicants novel fastening device is utilized.

'The structure of this device is clearly illustrated in Figures 7 and 8 of the drawings. From these figures it appears that said device, indicated as a whole byA the numeral 45, is substantially T shaped and comprises the oppositely extending flanges 46 and 41 and a securing shank 48. The

flange 46, as shown in Figure 7 of the drawings,

may have a sharpened end so as to form a prong for a purpose disclosed later. 'I'he flange 41 is offset as indicated at 49 relative to the flange 46 in the direction of the shank and is adapted to limit the extension of the fastener into the sealing strip and to provide a rm engagement between the fastener and the spark strip 29. Thefastening device 45 may be formed of a wire which is semi-cylindrical in section being bent into the desired shape. However, said device may be formed as a stamping or in any other desired manner.

When the fastening devices are utilized to fasten the flexible tubular sealing strips to their supporting members, said sealing strips may previously be perforated in order to provide a series of slits extending through the wall of the sealing strips. However, if the flange 46 of the fastening device vis in the formv of a prong said flange may be utilized to pierce the wall of the sealing strips.

`Thefastening devices are assembled with a sealing strip by projecting the flange 46 through the wall of said strip in order to dispose said flange interiorly thereof. The fastening devices may then be turned in order` to effect engagement between the offset flange 41 and the exterior. of the wall of the sealing strip. The shanks 48, each of which isshown in Figure 8 of the drawings as asplit shank, are then inserted through openings provided therefor in the supporting member whereupon the legs 50 and 5l of the 'l Shanks may be bent in opposite directions,

thereby securing the sealing strip to its supporting member. The disposition of the sealing strip, the flanges and shanks of a. plurality of fastening devices 45 is clearly shown in Figure 6 of the drawings. It will be apparent from the showing of this figure that adjacent fastening devices are so arranged that the flanges 46 thereof extend in opposite directions and that a. substantial bearing between said flanges and the sealing strip is obtained. If desired, the legs 56 and 5I of each of the shanks may be-soldered or welded to the supporting member. A further characteristic of each of the fastening devices is illustrated in Figure 6 of the drawings as well as in Figure 8. It will be observed from these figures that the angular relationship between the flange 46 and the shank 146 `of each of the fastening devices is less than a right angle. By this provision tight engagement between the sealing strip andl its 50 and 5I may not be properly ybent into engagei ment with the supporting member.

The invention, in its appncation to a mdined form of lift door 52, is illustrated in Figures 4 and of the drawings. The lift dOOr comprises a sheet metal panel 53 reinforced along its margins by means of the Z shaped reinforcing members 54, 55, 56 and 51. In its closed and lowered position the door is adapted to be frictionally supported upon a Z shaped track 58. For movement toward open position the door is adapted to be elevated relative to the track by means of a lift mechanism indicated in its entirety by the numeral 59, whereupon the door is supported for antifrictional movement upon said track by means of rollers 60. It will be apparent from Figures 4 and 5 of the drawings that the inner face of the door is substantially plane and that said face of the door is adapted to cooperate with a preferably continuous flexible tubular sealing strip 6I secured to the car upon which the door is mounted adjacent to the edges of said door. The flexible sealing strip 6I is shown secured to the front and rear door posts 62 and 63, to the depending leg 64 of an angle member 65 secured to the side plate 6,6 of the car, and to the depending leg 61 of an angle member 68 fastened to the fioor supporting member 69 which, in turn, is secured to the side sill 10. The fastening devices 45 hereinabove described are utilized in the manner set forth to secure said sealing strip to the car members noted. It will be apparent that as the door 52 assumes its closed position it will be forced inwardly toward the car side by means of indentures 1l provided in the track 58 so that said door will bear against the flexible sealing strip around its entire margin. While the arrangement for weather-proofing and dust-proofing purposes is illustrated and described in connection with lift doors, it will be readily apparent that the arrangement is applicable, as well, to the doors of the straight sliding type.

It is to be noted that with the arrangement disclosed the sealing strips present uninterrupted or uncut surfaces for engagement with door members.

It will be apparent A.that numerous changes and modications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention, which is to be limited only by the scope I of the claims appended hereto.
