METALLIC CAR DOOR.

Application filed Rovemb'er 5, 1925. Serial No. 67,176.

This invention relates to improvements in metallic car doors.

An object of the invention is to provide afabricated car door structure made up of sheet metal having a re-enforced body and edge arrangement afl'ording great strength, durability and simplicity in construction, this application being a continuation in part of my prior application, Serial Number 295,603, filed Ma 8, 1919, now Patent 1,560,526, granted llovember 20, 1925.

More specifically, the purpose of the .mvention contemplated herein is to provide a metallic door made upof a plurality of sheet metal panels provided with strengthening corrugation, together with re-enforcing edge members in the form of rolled sections of substantially 2 formation, in which one flange of the rolled section is secured to the panels substantially in the main plane of the door, and the opposite flange of which extends inwardly of said first flange and is disposed adjacent to or over-hangs certain of the corrugations of the body panels and is secured to the crests or peaks of the corruga-tions, the rolled sections being provided upon all four edges of the door and secured together to provide an articulated frame.

Other and further objects of the invention will more clearly appear from -the description and claims hereinafter following.

igure 1 is a front car door made up in accordance with my 111- vention.

'Fi the e 2 is a vertical sectional view of oor substantially von the line 2-2 of Figure L Figure 3 is a horizontal sectional view of the door construction substantially on the. line 3-3 of Figure 1. Figure 4 is a vertical sectional view similar to Figure 2, showing a slightly different embodiment of the invention; and Figure 5 is a horizontal sectional view similar to Fi showing the construction illustrated in ure 4.

Referring first to Figures 1 to 3, inclusive, the invention contemplates the provision of a metallic door of the usual rectangular form, andwhich comprises a main body portion made up of a plurality of metall1c

sheet metal panels

10, 11 and 12, said panels havin their adjacent horizontal edges overlappe and rigidly connected by welding, or by rivets, as indicated at 13. Each of the panels is made of relatively thin sheet metal,

Fig-

flange 19, extending elevational view of a' and in order to reduce its thickness to a minimum consistent with the necessary strength, each panel is provided with strengthening means, in this instance being shown as horizontally disposed corrugations 14, the opposite ends of the corrugations 14 terminating a suitable distance from the extreme outer edges of the 12, as indicated at 15, so as to provide marginal portions 16 and 17 outwardly of the corrugations, the marginal portions lying substantially in the main plane of the panels, which is the plane defined by the portions 18 of the door panels between the corrugations 14. At the rear edge of the door, and at the outer edge of the marginal portion 17, the

panels

10, 11 and 12 are provided with extensions forming a laterally disposed from top to bottom ofthedoor, said flange being designed to provide a spark seal adapted to 'co-operate with the f mounted, in the usual manner.

In conjunction with a door of this character, the edge construction is of great importance, dueto the concentration of strains thereon and the necessity forbracing the dooras a whole against warping and stresses in various directions. In providing a reenforced edge construction for the main body portion of the door, including the fabricat

ed panels

10, 11 and 12, re-enforcing memers of a. suitable character, in this instance rolled

sections

20 and 21 of shape, are associated with the edges of the door to rectangu ar frame therefor. At the top edge of the door the 2 bar 20 extends entirely across the door, and the outwardly turned flange 21 thereof is rigidly secured to the marginal portion 17 of the top panel 1.2 by means of welding or rivets, as indicated at 22, the web 23 of said 2 bar extending substantially normal to the main plane of the door, and the remaining flange 24 extending inwardly toward the center of the door and arranged so as to be disposed closely adjacentto, or over-hang,the uppermost corru ation 25 of the panel 12, the flange 24' 0% the 2 bar being secured to the crest of the corrugation by suitable means such as welding, or rivets, as indicated at 26. The Z bar 20 at the rear edge of the door has the outwardly turned flange 27 lying against the marginal portion 17, and

substantially Z rame upon which the door is articulated frame made up of is rigidly connected thereto by suitable means, such as Welding or rivets, as indicated at 28, the web 29 of'the Z barextending laterally ina direction substantially normal to the main plane of the door, 30 of the. Z bar is disposed inwardly so as to over-hang the end portions of the horizontal corrugations 14.0f all of-the

panels

10, 11 and 12, the flange 30 being secured to some or all of the corrugationsld at their peaks or crests by welding, or by rivets, as indicated at 31. The Z bar 20 at the forward edge of the door has the flange 32 secured to the marginal portion 16, has a laterally extending web- 33, and a flange 3a which over-hangs the endportions of the corruga tions 14 of the panels 10, 11 and 12', and is secured to some or all of said corrugations at their crests or peaks by welding or by riveting, as indicated at 35. At the bottom of the door, the 2 bar 21 is provided with a flange 36 secured to the marginal portion 18 of the bottom panel 10, the web 37 of said Z bar extending in a lateral direction substantially perpendicular to the main plane of the door, the flange 38 of said 2 bar extending inwardly and over-hanging the lowermost corrugation 39 of the bottom panel 10 throughout its extent, the flange 38 being secured to the crest of the corrugation 39 at one or more points, as desired, by means of welding or rivets, as indicated at 40.

A. door structure of the character above described, is particularly adaptable as a bottom supported sliding door, and the door is shown in the drawings as supported from its bottom for sliding movements. In the drawings, rollers 41- are shown as mounted upon the car structure by any suitable means .forming no part of this invention, said rollers 41 bein arranged so as to bear uponthe web 37 o the bottom 2 bar 21 to support the door for rolling movement, the flange 36, together with the mar inal portion 18 of the bottom panel 10, eing disposed behind the rollers 41 so as to prevent outward swinging of the bottom of the door, suitable well-known means, not shown, being also associated'with the top of the door to guide the same during the sliding movements of the door.

Referring to Figures 4 and 5 of the drawings, a somewhat different embodiment of the invention is illustrated. In this construction there are provided fabricated

panels

50, 51 and 52, in conjunction with the edges of which is associated arectangu'lar, 2 bars 53 in the same manner as described in connection with Figures 1 to 3. In this embodiment of the invention, the

panels

50, 51 and 52 are identical with the

panels

10, 11 and 12, with the exception that upon the forward and rear edge portions of the panels, said and the flange tion by any panels are provided with vertical corrugations 53 and 5- the corrugations 53 and 54 merging at their tops and bottoms with the horizontal corrugations 55 and 56, respectively, the forward and rear edges of the panels extending outwardly of the vertical corrugations 53 and- 54 to provide the nun ginal portions 56 and 57, and the top and bottom of said panels being provided with marginal portions 58 and 59, the marginal portions 57 58 and 59 being provided with angularly disposed flanges 60 at their other edges in the same manner disclosed in F igures l to 3, inclusive. In this construction.

' the Z bar 61 at the rear edges of the panels.

has its outwardly disposed flange 62 secured to the marginal portion 57, the web 63 of the 2 bar extending in a lateral direction substantially normal to the main plane of the door, and the remaining flange 64 of the Z bar 61 over-hangs the vertical corrugation 54,,as well as the ends of the horizontal corrugations 14, the flange 64 of the Z bar being secured tosome or all of the horizontal and vertical corrugations 14 and 54 at their peaks or crests, as indicated at 65. At the forward edge of the door the Z baris attached to the marginal portion 56, and is arranged with respect to the corrugation 53 in identically the same manner described in connection with the 2 bar 62 at the rear edge of the door, and similar reference characters are utilized to designate similar parts.

The top Z bar 66 extends across the face of the door, and the outwardly disposed flange is disposed to lie against the marginal portion 58, the web of the 2 bar being disposed substantially at right angles to the outward- 1 turned ange, and the inwardly turned ange over-hanging the corrugation 55, and being secured to the crest thereof by any suitable means. The bottom Z bar 67 has its outwardly turned flange disposed against the marginal portion 59, and has its oppositely disposed flange over-hanging the lowermost corrugation 56, said opposite flange being connected to the crest of the corrugasuitable means.

In order to brace the construction as above described, I provide a plurality of re-enforcing strips 68, 69, and 71. The top reenforcing strip 68 is; disposed on the inner side of the door, and has its inner edge secured to the main body portion of the door by any suitable means, such as rivets or welding, as indicated at 7 2. said strip spani which come .within door, bridges the corrugation 54, and has its outer end secured to the marginal portion 57 on the main body portion, the extreme outer edge of said strip being turned inwardly at an angle to the main portion thereof, and operates to provide a spark seal in the same manner as the turned flange portion 19 of the construction disclosed in Figures 1 to 3, inclusive. The strip 70 at the forward edge of the door has its inner edge secured to the main body portion thereof, spans the corrugation, and has its outer end connected to the marginal portion 56. The strip 69 at the bottom of the door has its inner edge connected to the main body portion, spans the corrugation 56 and has its out-er end portion secured to the marginal portion 59. The extreme outer edge of the strip 69 is turned laterally and rests against the laterally turned part of the marginal portion 59.

While I have herein shown and described the preferred manner of carrying out my invention, the same is merely illustrative, and I contemplate all changes and modifications the scope of the claims appended hereto.
