7 Claims.

This invention relates to railway freight cars and concerns itself essentially with the floor construction for said cars.

It is an object of this invention to provide doors for freight cars wherebyautomobiles and other bulky lading such as machinery may be fastened to said floorsl to prevent shifting of such lading during transit.

A further object is to provide freight cars having iloors to which bulky lading such as automobiles may be secured against shifting during transit, said floors being constructed so as not torimpair the general utility of the cars for shipment of other commodities.

A further object is to provide freight cars having floors to which bulky lading such as automobiles may be securedvto prevent shifting during transit, said floors being free of obstacles extending above the floor.

Another object is to provide freight cars having oors including a plurality of inserts or anchors to which fastening means for automobiles and other bulky lading may be secured.

A further object is to provide freight cars having floors formed with a plurality of inserts which lie below the surface of the floor.

Another object is to provide inserts or anchors applicable to the iioors of freight cars and presenting structure to which fastening means may be attached to maintain bulky lading against shifting during transit in said cars.

Other objects will become apparent as the description of the invention proceeds.

1n the drawings:

Figure l is a partial longitudinal sectional l view through a freight car embodying-the invention.

Figure 2 is a fragmentary plan with parts in section showing the novel iioor construction of the invention.

Figure 3 is an enlarged transverse section taken `on `line 3 3 of Figure Z.

Figure 4 is a partial elevation of a floor to which inserts or anchors of the present invention have been applied, illustrating attachment of` an automobile fastening device to said inserts.

Figure 5 is a plan View of one form of insert or anchor.

Figure 6 is a transverse section through the insert shown in Figure 5, illustrating its position in thefloor and the mode of attachment to the floor.l

Figure '7 is a longitudinal section through the insert and adjacent floor board, illustrating the manner of attachment of fastening means to the insert.

Figure 8 is a sectional view corresponding to Figure 7 ofa modified form of the insert.

Figure 9 is a sectional view corresponding to Figure 7 of la further modied form of insert.

In the drawings the numeral I designates generally a railway freight car of the house car type having a floor I I constructed in accordance with the present invention. It is to be understood that the type of freight car shown is for purposes of illustration only and that the invention is applicable as well to iiat and gondola freight cars. The freight car illustrated hasthe customary end i2, a roof structure embodying carlines i3 and a running board I4, as well as 10 side plates I5 to which stirrups I6 may be secured. The stirrups may be utilized in the positioning and maintenance of an automobile in inclined position as indicated in Figure 1 of the drawings. The automobile is so maintained by means of supports adapted to receive and secure the elevated wheels of the automobile through attachment of said supports to one of the stirrups. The particular construction of the supports forms no part of the present invention but will constitute the subject matter of a separate application.

With reference to Figures 2, 3, 6 and 7 of the drawings there is illustrated a floor construction comprising floor boards I1 and a plurality 25 of .inserts or anchors i8 secured to said boards. These anchors, as clearly shown in Figures 6 and 7 of the drawings, are preferably positioned within conforming openings I9 provided in the floor so as to lie below the upper surface thereof. The inserts or anchors illustrated in the figures of the drawing noted above preferably take the form of a casting substantially channel shaped in transverse section. They lcomprise a web or base portion 20 which connects upstanding walls 35 21 and 22. From these walls oppositely extending substantially horizontal flanges 23 and 26 project. These anges as clearly illustrated in Figure 6 of the drawings are adapted to be seated upon shoulders 25 and 25 formed in the 40 iioor and communicating with the openings I9. It is apparent that by this engagement the anchors I8 are prevented from falling through the openings lwhere such openings as illustrated extend entirely through the floor. The anchors are provided with threaded Shanks 2l extending from the web or base portion 2li oppositely from the walls 2l and 22. The shanks 2li are adapted to extend through openings provided in plate members 28 lying in abutting engage- 50 ment with the underside of the door and to be secured to said plate members by means of nuts threaded thereon. It is apparent that other means than that described may be employed to secure the anchors against upward movement relative to the door. The Shanks instead of being threaded may be upset so as to provide in effect a rivet head engaging the plate members 28 or, if desired, the shank may be provided with an opening through which cotter pins may extend to secure the anchors to the plate members. The walls 2l and 22 of the anchors are joined by means of a connecting wall 29 spaced above the web 20 and offset from the transverse center line of the anchor. By this arrangement of the connecting wall 29 engagement therewith of a hook member 3B provided at the end of 'an automobile fastening device 3l may more readily be effected. The relationship! assumed 'between the hook member and the anchor in order to effect operative engagement therebetween is clearly illustrated in Figure '1 of the drawings in which the hook member is shown in dot and dash lines. It may be noted that the shank 21 lies vertically below the connecting wall 29.

Two modified forms of inserts or anchors are illustrated in Figures 8 and 9 of the drawings. While the shank 21 shown in Figure 6 of the drawings is indicated as being cast integral with the anchor the modification illustrated in Figure 8 of the drawings utilizes a separate preformed bolt 32 molded into the anchor during the casting thereof.

In the modification illustrated in Figure 9 of the drawings the web or base portion 33 of the anchor 34 is provided with a countersunk opening 35 adapted to engage and retain the head 36 of a separate bolt 31. It is to be noted that plate members 38 and 39 engaging the underf a consideration of Figure 4 of the drawings. In

this figure there is illustrated a hold-down device formed of a plurality of chains adapted to engage over the tire casing of an automobile wheel. Ihe hold-down device 3l is provided with the hook members 33 at its ends. When the automobile has been properly positioned within the freight car the tires of said automobile are deflated. After deflation the hold-down device is positioned around the tire as shown in Figure 4 of the drawings and the hook members 3B engaged in the manner illustrated in Figure 7 with the connecting walls 29 of adjacent inserts or anchors. After this engagement has been eected the tire is then inflated and the hold down device is held taut in its engagement with the tire casing. While the foregoing is directed to the preferred manner of securing an automobile in a freight car against shifting during transit it will be apparent that the invention is not limited thereto but that other take-up means may readily be utilized in securing the hold-down device 3i to the inserts or anchors. In other words, although one manner of the employment of the novel floor construction in securing an automobile against shifting in a freight car during transit has been described it is apparent that said floor construction is independent of the hold-down means employed or of the particular manner of engagement of such means with the article to be secured to the door.

Numerous changes and modifications of the invention will be apparent to those skilled in the art. It is intended, therefore, that all such changes and modifications be ccmprehended within this invention, which is to be limited only by the scope of the claims appended hereto.
