RAILWAY-CAR CONSTRUCTION.

Application filed February 5, 1923. Serial No. 617,125.

To all whom z't may concern:

Be it known that I, ARGYLE CAMPBELL, a

citizen of the United States, residing at Chica-go, in the county of Cook and the State of Illinois, have invented a certain new and useful Improvement in Railway-Car Constructions, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in railway car construction and particularly to a novel reinforced, sheet metal plate usable in the construction thereof.

An object of the invention is to rigidify sheet metal plates entering into the construction ofA a` railway car by embossing therein designating markings which have heretofore been stencilled thereon.

Another object of the invention is to facilitate the maintenance and operation of railway cars of special construction by incorporating the instructions governing the operation of such cars in the form of rigidifying embossments pressed in portions of the car structure.

It is also an object of my invention to either entirely or partially dispense with the usual corrugations which have heretofore been used and substitute therefor descriptive characters, indicia, symbols or legends which will identify. the ownership of the car or serve as an advertising medium, such as a trade-mark, the same also providing a reinforcement to the {articular metal sheet or panel to which app ied.

Other objects of the invention will more clearly appear from the description hereinafter following.

In the drawings forming a part of this specification, Figure 1 is a side elevational view of the side door of a grain and merchandise car reinforced with my improved system of embossments or indentations. Figure 2 is a sectional view taken on a line corresponding substantially to line 2-2 of Figure 1. Figure 3 is an end elevational View of the end of a gondola car reinforced by having a typical trade-mark incorporated therein. Figure 4 is a sectional view taken on a line corresponding substantially to line 4-4 of Figure 3. Figure 5 is a portion of the side of a car showing my improved system of reinforcement applled in modified forms. And Figure 6 is a sectional view taken on line 6-6 of Figy ure 5.

Referring rst to Figures 1 and 2 showing my system of reinforcement as applied to the side door of a grain and merchandise car of the type described in my pending application Ser. No. 613,328 filed January 18, 1923. wherein double doors are adapted to slide in opposite directions, 10 indicates the side of the car. 11a track on which the doors slide, 12 a guide to restrain the doors against outward movement and 13, 14, 15 and 16, respectively, panels which form part of the doors. Panels 13 and 14 being secured together by rivets 17 constitute the lefthand portion of the door and panels 15 and 16 together constitute the right-hand portion of the door. Said doors are adapted to be drawn together by means of mechanism consisting of shaft 18 mounted in brackets 19 75 and crank arms 20, rigidly secured to shaft 18. Said arms 20 have hook-shaped members 21 pivotally mounted thereon adapted for engagement with the lefthand portion of the door, whereby, through the rotation of the shaft 18 by means of handle 22, the doors are drawn together. The doors are further locked in position by locking handle 22 to a hasp 23. The opening of the doors is effected by prying one door against the other by movement of the downwardly extending lever arm 2A in the indicated direction. Said lever 24 is pivotally mounted on a bracket 25 rigidly secured to the door and a sliding bar 26 is pivotally mounted on the short end of the lever by means of pivot 27. Said sliding bar 26 extends to the opposite door and relative movement between the doors in an opening direction is effected bylevering the right-hand door against the left-hand door through the medium of the sliding bar 26 and lever 24, all as more clearly described in my said application.

It w1l1 be appreciated by those skilled in the art that the eiicient operation of such a combination of mechanism is dependent upon the necessary instructions being issued to the operators in order that the mechanisms for opening, closing, locking and sealing the doors may at all times be utilized in a proper manner. In order to provide for the proper instruction of the operators handling such cars it has been customary to stencil the required instructions on the door '110 but such a procedure is not effective inasmuch as the stencilling wears off after a short time in service and furthermore the entire door may be corrugated for the purpose of stiffness thereby leaving the door devoid of a suflicient area of flat surface on which to stencil the necessary markings and instructions. I overcome this difficulty by embossing or pressing or incorporating the markings and instructions in the door itself and in such a manner that they form rigidifying embossments and prevent -buckling of the metal plate. 1 not only find it desirable to emboss instructions in this manner but also find it very advantageous to thus designate the ownership of the car in a way which will permanently identify the car even though painted over. lith the present sys tem of interchange of cars between various lines and countries, it frequently happens that a car has to undergo repairs on a foreign line when it is necessary to dismantle such car. Then, during the rebuilding of the car it frequently happens that a portion of another car composed of inferior maten rial or an element already in an advanced stage of corrosion is inadvertently substituted for the original part. This aspect of the case is even of greater importance at the present time inasmuch as there is a tendency for carriers to embody in the manufacture of railway cars, plates which are composed of alloy steel having high resistance to corrosion and inasmuch as the cost of such metal is higher than commercial steel it is very desirable for a carrier t0 provide against substitution of the parts when the car has passed beypnd its jurisdiction. Furthermore, my system of embossment may be utilized to form a valuable advertising medium in making a distinctive symbol or trade-mark more widely known.

ln the particular arrangement illustrated in Figures 1 and 2, l have formed the doors in a series of panels which are formed separately and may he quickly assembled. The pane s are referably formed with flanges along the finir margins thereof. Takin panel 13 asan illustration, vertical flange 2 and horizontal flange 28 are turned outwardly while vertical flange 29 is turned inwardly and along the upper edge thereof the marginal flange 30 is turned outwardly in the form of a U. The panel is thus stiflened along the four marginal edges thereof and the embossments rigidify the main body of the plate between the respective margins of the panel. 1n order to secure the greatest amount of stiness with the minimum amount of lettering, it is desirable to stagger the various rigidifying characters forming the marking of a panel in such a manner as to provide for continuous reinforcement between the various characters. This may ce conveniently accomplished as indicated,

Lesaeao by the letters 31 in panel 13 which are disposed on a diagonal line relatively to the margins of the panel and furthermore are disposed in such relation to each other that the letters in the successive .rows do not come directly beneath each other. The space on the panel not covered by lettering may be suitably rigidified by embossments as shown at 32 and 33.

1n panel 14, where the amount of lettering on the panel as indicated at 34 is comparatively limited, there is no objection to corrugating the unlettered portion of the anel in the manner indicated at 35 and 36.

he arrow 37 indicating the direction of movement of the lever 24 also forms a part of the rigidifying system. In panel 15, I have shown by way of example a symbol 38 illustrative of a trade-mark and l have also shown lettering 39 illustrative of the initials of an owner carrier. In panel 16 I have illustrated by way of example the instructions as indicated at 40, governingthe operation of the closing, locking and sealing mechanism. The preferred procedure in this instance consists of having horizontally eX- tending corrugations 41, 42 and 43, respectively, acting as beams between the stiffened vertical margins of the panel and interposing lettering as indicated at 40, 44 and 45 to stifi'en the space in a vertical direction between the existing rows of corrugations. The indicating arrow 46 further acts as a strengthening member.

n Figures 3 and 4, I have shown my improved system of construction as applied to the end of a gondola car and in this instance l have illustrated a trade-mark. ln this particular instance, l have depressed the central portion 47 of the plate 48 beyond the main body thereof and embossed on the plane surface so depressed, the lettering 49 thereby stiffening this portion of the plate vertically. The stiflening in a horizontal direction is effected by means of corrugations 50 which define the boundary of the central panel of the trademark. Said corrugations 50 are pressed outwardly from the main body of the plate 48 and irrl the opposite direction to depressed portion 47 thereby providing a beam of great strength to resist bulging of the end. Other portions of the trade mark adjacent the aforesaid corrugations 50 are embossed outwardly from the main body of the plate as indicated at 51 and stiflened with lettering 52. Certain of the letters, as indicated at 53, are embossed directly in the main body of the plate to stiften such portion thereof. rlhe outer boundary of the trade-mark is indicated by a corrugation 54. corrugation thus placed defines the outline of the symbol more clearly.

From the foregoing description 1 t will be evident that my system of rigidifymg steel lOO mensa@ plates permits of the distortion of the plate in opposite directions from'the main body of the plate providing for a portion depressed to one side of the main body of the plate and for a portion upstanding to the opposite side thereof. The bulb angle 55 and bottom angle 56 riveted to the top and bottom margins o't the plate, respectively, represent a construction commonly used. Stiffening of the vertical margins ot' the plate may be conveniently carried out by tlanging the plate inwardly as indicated at 57-57.

ln Figures 5 and 6, lhave illustrated my system of reinforcement as applied to the side of a car. Two dierent panels, illustrating various forms of embossments, are shown. ln said illustrations, 58 represents the side top chord of the side of a car, 59, the side bottom chord thereof, 60 the end of the car, 61 one of the panels formed with vertical tlanges62 and 63, respectively. Said panel 6l is rigidiied by a series of initials 6ft which are so interwoven as to present a single continuous reinforcement. The adjacent panel 65 is also formed with vertical lianges 66 and 67, respectively. The various panels are united through the medium of the aforesaid vertical flanges by means ot'rivets 68. ln the panel 65, the rigidifying corrugations 69 intersect each other and the surfacebetween such corrugations is rigditied by means of designating symbols preferably in the form of letters as indicated at 70, 71, 72, 73 and 74C, respectively. Letters 7 3 and 74 which are disposed one within the other, provide an embossment of great strength and are illustrafor such a combination.

While I have shown and described certain embodiments of my improved railway car construction, the same are merely illustrative, and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

What l claim is: l

l. As anarticle of manufacture a sheet metal body plate for the vertical parts of railway cars, the parts of said plate within its margins being corrugated, stiffened and strengthened with integral intelligence-conveying lettering arranged out of the main plane of said plate so as to resist the bending of the plate on various cross lines.

2. lAs an article of manufacture a sheet metal body plate for the vertical parts of railway cars, the parts ot said plate within its margins being corrugated, stiffened and strengthened with integral intelligence-conveying lettering arranged out of the main plane of said plate so as to resist the bending of the late on various cross lines, the letters running one into another and effecting continuity of reinforcement. 3. As an article of manufacture a sheet metal body plate for the vertical parts of railway cars, the parts of said plate within its margins being corrugated, stiiieneda and strengthened with an integral intelligenceconveying character arranged out of the main plane of said plate so. as to resist the bending of the plate on various cross lines.

In witness that I claim the foregoing I have hereunto subscribed my name this 30th day of January, 1923.
