'WILLIAM ERASTUS WILLIAMS, 0F CHICAGO, ILLINOIS.
Specication of Letters Patent.
Application led September 2, 1913. Serial No. 787,675.
ToaZZ whom t may concern.'
Be 'it knownl that I, WILLIAM ERAs'rUs WILLIAMS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, with a post-ofiice address at #331 South Clinton street, have invented a new and useful Improvement in Railway-Car Doors, of which the following is a speciication.
The object of my invention is. to produce a metal door as light as a wooden door, and at about the same cost, and one that will withstand the abuse that car doors get m service.l
My door may be used for many other purv poses as well as railway car doors.
In general terms my door consists in a sheet of metal that is corrugated, or formed with stiening depression as desired, and bound on its edges with heavier sections and stiiened crosswise by suitable cross-strips, all of which binding and cross-strips are arranged to give great strength and rigidity.
Reference will be had to the accompanymdrawings in which,
igure 1 is a vertical elevation of my door, as it appears on the side of the car.
Fig. 2,- is a section through one of the stitiening cross beams, or rails.
Fig. 3,- is a view similar to that of Fig.
. 2, showing an'alternative construction.
Fig. 4,- shows a section of the back stile, or vertical edge of the door. v
Fig. 5,- s the same as Fig. 4, with a reinforcing plate added on the inside.
Fig. 6,- is the same view as Fig. 4, showing(1 in section a stile made of two pieces.
ig. 7,-* is a section of the door just above the upperl cross rail. y p
Fig. 8,- is a sectional detail, showing the back edge of the door when a stop diierent from that shown by Figs. 4, 5 and 6 is used.
Fig 9,- shows a section of the lower .right-hand corner of the door when no lip or fiange is used on the back stile.
Fig. 10, is a view, similar to that of Fig. 8, differing only in the form of section used for the back stile.
Fig. 11,- is the same also as Fig. 8 only with a different form of section for the back stile. Fig. 12,-- is a vertical sectional view through the door when same is fixed to the car.'
Fig. 13,- is a vertical elevation of one of the door hangers showing its fastenings securing it to the door.
Fig. 14,- is an elevation of one of the stldening, or intermediate rails showing its fastenings securing it to the door sheet.
vlPatelated Sept. 1S, 1917..
Fig. l5,- is an alternative form for the top rail of the door and its hanger.
Fig. 16,- shows an altelnative form forl the top rail of the door. y
Fig. 17,- shows a section of-a -form of intermediate cross rail.
Fig. 18,- is a section through an intermediate cross rail.
Fig. 19,- is a vertical sectional detail of one of the corners of the door.
Fig. 20,- is a detail showing in dotted lines the union of the corrugated sheet with the top and bottom rails.
In the drawing, l indicates the ordinary car body to which my door is applied. I
make the main sheetof the door of corrugated iron 2, which is bound on its back edge with a vertical stile-piece 3, made of a special section having a flange 4, which abuts against a door cleat, or stop 5, ordinarily made of wood, but sometimes made of a curved strip of metal, 6; see Figs. 8 and 10. When the metal strip 6 is used, the ange 4 is bent, as is shown by 7 Fig.
10. The front edge, or stile of the door is an ordinary channel section 8, Fig. 7.
Instead of the special section 3, I may use an extra piece 9, in order to produce the desired flange shown at 4. See Figs.
' to the webs of the channels, as is shown at 13.
In the construction shown in Fig. 5, I use a reinforcing plate 14 and weld it and the flange 12 and the web of section 3 all together as is shown at 15. kI also weld through the sheet 2, and anges of channels asis shown at 45.
When the strips'9 or l() are used, they are spot welded to the channel sections as is indicated at 13 and 16, Figs. 6, 8 and 1l.
The top and bottom rails of the door may be ordinary channel sections 17 and 18, as
is shown by Figs. 12, 13, 19, and 20 or the top rail may be of a special section 19, Fig. 16, where there is provided a ilange 20. This iange may be the built up section shown in Fig. l5, where to the channel 17 the angle 21 is secured by welds 47.
The corrugated sheet 2, is vembraced at Y'each end at the to and bottom by the chan- The corners of the top and bottom rail `channels 17 and 18 and the vertical stilev channels 8, 3 orll, are connected together at the corners in any suitable manner, but I prefer to connect them as is shown by Figs. 9 and 19, wherein I have made indentations 23, in the ends of the webs of the channels,
wherein I yseat an angle piece 24, which is spot welded by welds 25, to the channels.
The door is supported on any suitable track rail 26-by means of the rollers 27 ,-f
held in hanger blocks 28. The latter are bolted or riveted at 29,-to the corrugated sheet at summits of the corrugations.. Projections, or arms 30, on the hanger blocks 28,- extend around the summits of the corrugations to which they are attached and reach up in the valleys of the corrugations andi bear on theinside of the web of the tbp channel rail at 31.
Rivets 32, are shown as fastening the arms 21 to the web of channel top rail. The ends 31, of arms 30, carry the load of the door independently of `the fastenings 29 and shouldl fastenings 29 give way, the hanger would still vcarry the door safely, as the hanger 28, cannot move horizontally in relation to the door, owing to its embrace of' the summit ofthe corrugation, and the ends 31, of arms 302 support the door. in the vertical plane of lts center of gravity.
f The intermediate, or cross-stiiening rails 33, and 34, Fig. 1, may be made in various ways, but I prefer the construction shown in 17 in order toll the spaces 39 Fig.l7, that otherwise would appear open and would make possible the undesirable attachment of the tackle while loading the car through opposite door when one door is closed. The angles 35 and 37 are spot welded at 40 to the electrode on that side to contact with the sheet at the bottom of the corrugation, or what is the summit on the other side. Thus I may make the spot welds 40 with great despatch.
In Fig. 3, the angles 42 and 43 which may form the 'intermediate cross rails are" placed slightly asunder to permit the weldln 44 without the holes 41. In the bottom ra or channel 18, I provide holes 46 for the escape of water, dust or other accumulations. Where I have shown spot welds, rivets, bolts or other suitable fastening devices maybe used, but I prefer to use 'welds.
What I claim is l.. The combination' withaf corrugated metal sheet forming a door body, of channel members covering the edges of the sheet, re-
spectively, spot welded thereto, and forming the edge faces of the door, and right angle cornerplates sunk in and Hush with said faces and spot welded in place at the angles .of the door.
2. A door composed of a sheet of metal corrugated for stiiiening ribs in one direction and stifened transversely of the corrugations by cross-rails on each side of the sheet and adjacent to each other and welded to the summits of the corru ations, said rails being .provided with e orations for allowing s the passage o the electrode throughl the rail to facilitate the welding.
3. door consisting of a metal sheet provided with vertical corrugations, channel respectively, a cross rail on one face of the sheet, and an approximately registering members embracing the edges of the sheet,
cross rail located upon the opposite face of the sheet and fitting its corrugations, said channel members and rails being spot welded to the corrugations of the sheet.
4. A door. composed of a sheet of metal provided with vertically arranged indentures or corrugations for stiffness and with flanges turned at right angles on its vertical edges, with a channel section binding forming stiles on the edges with internally vextending flanges embracing the sheet, said stile welded to the sheet both at-the web and flange of the channel stile.
5. A freight car door composed of a sheet of metal corrugated to form on each face a series of equal vertical ribs, 'a channel member closely fitting over the upper end of the corrugated plane sheet, and a similar channel member fitting in like manner over the lower end of the sheet, each channel memher having a piane vcentral web perpendicuscribed my name on this 29th da of Aular to the lane of the door and provided gust 1913 in the presence of two su scribing with marginal flanges tting, respectively, Witnesses.
