ROBERTAD. HAWKINS, OF WILMINGTON, NORTH CAROLINA.
END STRUCTURE FOR RAILWAY CARS.
Application filed March 2., 1923. Serial No. 622,34.
To all whom t may concern.:
Be it known that 1, ROBERT D. HAWKINS, residing at Wilmington, county of New Hanover, State of North Carolina, and being a citizen of the United States, have invented certain new and useful Improvements in End Structures for Railway Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the saine, reference being had to the accompanying drawingswhich illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modiiications thereof within the scope of the claims will occur to persons skilled in the art.
Metallic ends for railway cars have been devised and are now in extensive use which are made of a plurality of metallic plates having parallel corrugations formed therein extending alternately inwardly and outwardly from the neutral axis of the corrugated panel. The corrugated plate is of ample strength to resist the shocks of the shitting lading and to resist the torsional strains set up by the weaving of the car.
1t is necessary, however, to line these Inetallic ends with a wooden lining so that the car may be used to transport any kind of lading. The lining prevents the moisture, due to condensation on the inside of the metal plate, coming in contact with the grain lading and causing mildew, or if the car is loaded with cement, this moisture would cause hardening of portions of the cement requiring resacking. There are also limitations regarding the loading of explosives prescribed by the Bureau of Explosives of the Interstate Commerce Commission. 1t is frequently found necessary to drive nails into the side or end of the car when blocking the lading.
Corrugated ends have been lined by positioning nailing strips within the corrugated portion and nailing the lining to such nailing strips. These nailing strips, of course, are subject to shrinkage which may cause a loose lining.
One of the objects of my invention is to eliminate such nailing strips and secure the lining boards directly to the corrugated end in such a manner that each lining board bears directly against the inwardly projecting apices of the corrugations. Any thrust or load imposed upon the lining board is therefore transmitted directly to the corrugated end and acts as a beam for only the short span of the distance between the apices and t-he inwardly projecting corrugations. This construction, therefore, materially strengthens the lining boards, thus reducing the possibility of their breakingv or splitting. Another object ofl the invention is to provide vmeans to hold the boards .directly in contact with the apices of the inwardlv projecting corrugations. v
Another object of the invention is to strengthen the corrugated endby using the lining to distribute the load over several of tliecorrugations which is accomplished by positioning the boards vertically it the corrugations are positioned horizontally or vice versa, or so that the direction oli' the corru- `gration is substantially ninety degrees from the direction of the lining boards.
Another object of the invention is to have the bolts so positioned that the nuts thereon are protected.
Another object is to provide means whereby the bolts securing the lining to the corrug-ated end may be pulled up tightly without distorting the bolt.
My invention may be used on box, gondola, stock or other types of railway equipment.
1n the drawings:
Fig. 1 is a front elevation of a railway car with my invention applied thereon.
Fig. 2 is a cross section drawn along line 2-2 of Fig. 1.
Fig. 3 is a section drawn along line 3 3 of Fig. l.
Fig. 4 is a fragmentary enlarged view ot' a portion of Fig. 2.
Numeral 1 represents the center sill; 2 the flooring; 3 the end sill angle; 4 the striking casting; 5 the side and end sill connection: 6 the corner post: 7 the siding; 8 the side lining, all of the usual freight car; 9, 10 and 11 are metallic plates with corrugations 12 formed therein in the usual manner. The corrugated plate has corrugations projecting on either side of line 13-14 in Fig. 4 forming outwardly projecting corrugations 15 ,and inwardly projecting corrugations 16. The lining boards 17 extend in a direction substantially ninety degrees from the direction of the corrugations, so that they bear directly against the apices of the inwardly lll) projecting corru'gations 16, as shown in Figs. 2 and l. The bolts 18 pass through the inwardly projecting apices and by means of nuts 19 and washer 2O hold the boards' 17 in contact therewith. The washer 20 is formed to lit the contour of the corrugated plate, as shown in Fig. 4. p l
A metallic strip 22 entends on the inside lot kthe lining boards so that it is not necessary to bolt every board to every corrugation unless desired. This is illustrated in Figs. 1 and 3. This `metallic continuous washer may be let in the` lining boards so that the inner surface of the end will be flushl as shown in Fig. 4.
What I claim is:
1. An end `for a railway car comprising a metallic panel with inwardly and outwardly projecting parallel corrugations formed therein, a wooden lining having contact with the apices of the inwardly projecting corruga'tions, bolts passing through said apices to hold said lining in contact with said panel, and bearing washers for said bolts tting the contour of said corrugations.
2,. An endjfor a railway car comprising a inetal panel with a plurality of inwardly and outwardly projecting horizontal corrugations formed therein, a plurality off vertical boards lforming a lining for said panel havcontact with the apices of the vinwardly projecting corrugations, a metallic strip on the inside of said boards, and securing means passing through said `apices, boards and strips whereby said boards are held in Contact with said corruga'tions.
