Specification of Letters Patent.

Patented Oct. 2, 191 '7.

Application filed November 26, 1915. 7 Serial No. 83,633.

To all whom it may concern:

Be it known that I, Hnnenn'r E. VAN DORN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-End Constructions; and I'do hereby declare that thefollowing is a full, clear, and exact descri tion of the same, reference being had to t e accom anying drawin and to the numerals of re erence marked t ireon, which form a part of this specification.

Certain types of steel endshave in the past few years come into wide use to meet the persent severe conditions of heavily loaded cars. However, the types of cars are changing, steel construction taking the place of wood construction, and furthermore the cars are larger and, with the steel construction, very much heavier, and more is being required of the ends. All steel ends now made are formed to produce the greatest strength for the particular type and weight involved. The steel in the end can only be pressed a certain depth for its weight'without being fractured, and in order to. produce steel ends of sufficient strength to meet increasin conditions, the corrugations must be ma e deeper, which necessitates using heavier plates.

An objection heretofore existin in the use of metal ends is the heat con uctivity of the metal which causes the end, for instance under intense sunlight, to absorb the li ht and transmit the heat to the interior 0 the car. By this invention a stronger end than heretofore is roduced without materially increasing t e total weight of the structure, and furthermore, due to the provision of a dead air space, a less co-efiicient of heat conductivity is obtained.

This invention relates to what may be termed a double plate car end constructed of metal for attachment on cars, and one of inherently greater strength than ty es of single ends heretofore constructed. us to the fact that the combined depth of the corrugations in the double plate end is nearly twice that of the single plate end, and since the plates are made of lighter material, the weight of the double plate end is about the same as that of the heavy single plate end of less strength.

It is an object therefore of this invention to provide a metal car and construction embracing a plurality of sheets of metal corrugated and laid against each other and secured oneto another for attachment to the end of a car.

It is also an object of this invention to construct a car end comprising a plurality of sheets of metal secured one to another and each corrugated and so disposed that the corrugations of one sheet extend inwardly within the car and those of the other sheetoutwardly from the car with the contacting surfaces of the plates riveted one to another. to aflord substantially a unitary structure.

It is also an object of this invention to construct a car end comprising a plurality of corrugated sheets of metal, the corru ations of each plate extending outwardly from the surface of the plate so that the inner surfaces of the plates and corrugations lie in the same plane, and may be secured by rivets or bolts to one another, said corrugations being continuous and, if desired, horizontal on one side and vertical on the other, or disposed in any relation to one another to reinforce each other and extending inwardly within the car or outwardly from the car.

It is also an important object of this invention to construct a double walled car end having a space between its walls to afl'ord a heat insulating space or to receive a filling of insulatin material therein.

It is furt ermore an important object of this invention to provide a unitary double end structure for cars whereby one member serves to reinforce the other and so constructed that in the event of one member being already attached on the car another reinforcin member may be secured thereover, eit er on the interior or exterior of the car, to afi'ord a double plate metal car end.

It is finally an object of this invention to provide an improved type of metal car end structure self sustaining and capable of withstanding stresses applied on either side thereof, and not requiring auxiliary reinforcement members within or on the exterior of the car.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown in the drawings:

As shown in Figs. 1, 2, and 3, the car body is denoted as a whole by the reference numeral 1, and attached on the end thereof is a double late end comprising an inner plate 2, having circular or concentricall arranged corrugations increasin in dept successively from the outer e ge of the plate toward the middle, and another simiarly constructed outer plate 3, said plates arranged such that the inner corrugations of each plate contact one another, as clearly shown in Fig. 3, to permit attachment thereof by rivets 4, one to another. The margins of said res ective plates are bent at right angles and ie flat against one another, and are bent around the end posts of the car body 1, and secured thereto in any suitable or convenient manner to afford a ri 'd attachment of said associated plates with the car.

In the form of device illustrated in Figs. 4, 5, and 6 the car body is denoted as before by the reference, numeral 1 and a pair of inner vertically di osed en plates 5 and'fi are provided, -wit their central vertical margins riveted one to another by rivets 7, and secured on the exterior of the carover said vertically disposed corru ted plates 5 and 6, are similarly corrugate lates Sand 9, which, however, are disposed orizontally fromthe car and the inner with the central connected margins of said outer row of plates secured by rivets 10, which also extend through said inner plates 5 and 6, as clearly shown in Fig. 5. The vertical row of rivets 7., which secure the central margins of said inner lates 5 and 6, to ther also extend throng zonta exterior plates 8 and 9, as clearly shown in Fig. 4. The side margins of the respective inner plates 5 and 6, and outer plates Sand 9, are laid flat against one another and bent around in right angled relation to the body or frame 1, of the car, as clear] shown in Fig. 6, and securely attached thereto in any suitable manner.

In the form of construction illustrated in Figs. 7, 8, and 9, I have shown attached to the car body or frame 1, an inner plate 11, the corrugations of which are disposed vertically over the entire surface thereof, and secured on the exterior of the car flat against said inner plate 11. is another plate 12, with the corrugations thereof extendin horizontally over the entire surface thereo and at points on said respective plates where the corrugations contact one another, rivets 13, are secured thereto to rigidly connect said plates one to another substantially as a unitary structure. As in the constructions before described, the side margins of said plate are laid flat against one another and bent around the corner osts of the car body and secured thereto in any suitable manner. a

In the structure illustrated in Figs. 10 and .11, I have shown the car body 1, as already equipped with a transversely corrugated end plate 14, although the particular construction or shape thereof is immaterial and for the purpose of reinforcing the same, l have shown another corrugated plate 15, mounted on the exterior thereof with rivets 16, extending through said respective plates at the points. at which the corrugations contact one another, and, al-,

though no marginal connections are shown between said lates, it is obvious that such may be provi ed if deemed necessa As shown in Fig. 15, the outer p ate denoted as a whole by the reference numeral 20, is corrugated horizontally and inwardly relative the sheet, but outwardly relative the car and the inner plate 19, secured thereto is corrugated vertically and outwardly, that is inwardly with res ect to the car. In Fig. 16, the outer plate enoted by the reference numeral 21, is corru ated horizontally and outwardly from. t e sheet and 7 plate 22, secured thereto is corrugated vertically and outwardly from the sheet.

. In the constructions'illustrated in Figs. 12, 13 and 14, I have shown difl'erent methods of connecting the lower margins of the plates to the car frame. In Fig.- 12,

said horithe margin of the outer plate, denoted by the reference numeral 17, is bent outwardly, and the margin of the inner plate, denoted by the reference numeral 18, is bent inwardly and each is secured independently to the car frame.

In Fig. 13, the construction illustrated shows the margins 17 and 18, of the plates laid flat against one another and .secured between the frame members of the car body, whereas in Fig. 14, said margins 17 and 18, are laid flat against one another'and both bent outwardly in right angled relation and secured upon the car frame.

The operation is thought to be obvious from the description. The corrugations in the plates serve to greatly strengthen the same in resisting stresses applied on either surface thereof, and it is obvious that where two plates are used the associated plates are capable of withstanding even more than twice that of either of the plates when used alone. The greater rigidity of the'entire structure is due to the connection of the two plates at the difl'erent points thereof, which serves to distribute the stress from one late to another when stress is ap lied upon either one of said plates. The d ziuble plate construction, as ointed out, may be as light or lighter in weight than the single heavy plate construction. 1

Another important feature of the double plate end is the provision of the air space between the plates, which may or may not be a dead air space, depending u on the particular type of construction, ut the space, whether filled with a material or not, in any event serves as an insulating means to prevent rapid conduction of temperature changes through the car end.

Of course, while I have illustrated and described my invention for use as a car end, it is obvious from the construction described that it may be used as well for a car side or as a part of any metallic construction, if desired.

I am aware that various details of construction may be varied through a wide outwardly from the main surface, and with said sheets secured to one another with the corrugations thereon registering to afi'ord an air space between said sheets.

2. A structure of the class described comprising a pair of circularly and concentrically corrugated lates secured flat against one another aifor ing a plurality of circular concentric air spaces therebetween, and with means secured to and through said plates between said air spaces to hold said plates attached to one another.

3. A structure of the class described com rising concentrically corrugated plates liaving circular corrugations, and with said plates laid flat against one another with the corrugations registering to afford circular air spaces between said plates, and attaching means secured through said plates to hold the same attached at contacting points of said plates between said circular air spaces.

4. A structure of the class described comprising plates having curved concentric corrugations therein of varying depth, said plates secured fiat against one another with the corrugations in register to afiord a plurality of air spaces circular and concentric with respect to one another, and each of different depth, and means securing said plates one to another.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
