7 Claims.

This invention relates to securing means in general and in particular to securing means for use on lining of railway vehicles.

The lining of railway vehicles has in the past been secured to the car frame by nailing the same to a heavy piece of wood bolted or otherwise secured to the posts and other frame members of the car. These heavy wood posts and frame members did not add any strength to the car but only added to the dead weight and cost without serving any useful purpose other than a means for securing the lining. It is an object, therefore, of the present invention to provide securing means for fastening the lining directly 16 to the metal car post or other framing members.

A further object of the invention is the provision of fastening means for'securing the lining to the metal car frame, which means are so formed as to draw the lining tightly against the framing.

These and other objects of the invention will be apparent to persons skilled in the art from a study of the following description and accom-' panying drawing, in which Figure l is a sectional view taken substantially on line ll of Fig. 3 and showing a .side portion of a railway car structure;

Fig. 2 is an inside elevational view of the structure shown in Figure 1;

39 Fig. 3 is a sectional view taken substantially oh line 3-3 of Figure 1;

Fig. 4 is a perspective'view of the improved clip used in Figures 1 to 3 inclusive;

, Fig. 5 is a sectional view similar to Fig. 3

but showing a modified form;

Fig. 6 is a partial sectional view similar to Figure 1 and showing the modified clip of Fig. 5;

Figs. 7 and 8 are sectional views similar to Figs. 3 and 1 respectively but showing a furthe Figs. 9 and 10 are sectional views similar to Figs. 7 and 8 respectively but showing a slight modification thereof, and r Fig. 11 is a sectional view similar to Fig. 1 and showing the securing clip of Fig. l as applied to a different type of lining. Referring now to the drawing in detail, it will be seen that the invention has been shown as applied to a railway car formed with the conven- 50 tional side sill 2, plate 4, side sheathing 6 and roof 8. Any desired form of side post may be used to form the side framing but in the present instance a post ID of Z-section is used having its one flange H connected to the-side sheathing, 55 while the other flange I2 is spaced inwardly modification;

therefrom and connected to the outer flange by an outwardly directed web H. The side sill supports one end of the flooring It with the usual sealing or grain strip i8 applied thereabove to prevent leakage of lading, while the customary 5 ceiling 20 is secured in any desired manner to the roof structure. The lining IQ for the side walls is applied directly to the side posts or other framing members and in the present instance this is accomplished in part by welding or otherwise 10 securing a U-shaped clip 22 to the lower edge of the inner post flange. This U-shaped clip projects inwardly of the car from the post, thus providing a pocket within which the lower edge of the lowermost lining board may be received. As 16 clearly shown in Figures 1 to 10 inclusive the lining boards are of the customary tongue and groove type having a tongue 24 along one edge and a groove 26 along the other edge, which tongue and groove are adapted to engage and g interlock with the mating element on the adjacent boards as is customary. As clearly shown in Figs. 1 to 4 inclusive, the tongue and groove boards are secured to the posts by means of fasteners 28, which fasteners are adapted'to engage 5 in slots 30 punched or otherwise formed in the inner flange of the side posts or other framing members. The fasteners are of angular formation having notches 32 cut therein to form a T- shaped end or anchor portion with the leg there- 3 of of such a width as to permit rotational movement within the slot 30 of the post. With the leg of the T-shaped portion s0 proportioned the fastener may be inserted into the slot of the car post and turned ninety degrees, thus bringing the 35 hook 36 of the T behind the flange of the post and preventing the removal of the fastener in a horizontal direction. The other leg of the angular shaped fastener is formed to provide a prong 38 having its inner surface 39 inclined outwardly w in' order that this surface may cooperate with the lining to force the same inwardly against the post as the fastener is driven downwardly. In order to secure sufficient grip upon the lining the tongue of each lining board is removed over a limited area at each post sufficient to receive the fastener, andat the time the portion of the tongue is removed, a notch is preferably cut in the board to prevent splitting thereof when the prong is driven downwardly into the board. It 60 will thus be seen that in order to fasten the lining to the notched posts, it is only necessary that the fastener be inserted in the post notch, turned to an angle of ninety degrees to lock the same to the post, and then driven downwardly into the board to draw the same inwardly against the post or other framing member,

As clearly shown in Figs. 5 and 6 the tongue and groove lining boards may be secured to the framing by notching the web of the post, as at 40, in order to receive the inner end of the modified fastener. This modified fastener is preferably made of flat material having one end bent to pro- 'vide a U-shaped portion 42 adapted to engage within the web slot of the post and with an angularly disposed opposite end portion 44 pierced and adapted to receive a nail or other securing means 46. In this instance the fastener is hooked into the web of the post and the nail or other securing means driven downwardly into the board at a substantial distance from the edges thereof in order to prevent splitting and draw the same tightly against the post or other frame member. In this form also it will be necessary that a portion of the tongue and of the board immediately therebelow be removed as at 48 in order that the upper surface of the fastener may be positioned substantially flush with the base of the tongue.

Figures 7 and 8 disclose a slight modification of the form shown in Figures 5 and 6 and in this form the web of the post is provided with a keyhole type of slot having upper round portion 50 merging into a vertically elongated slot portion 52. The fastener is formed with a head 54 which together with the short shank portion 55 provides a substantially T-shaped head terminating in an outwardly directed shank portion 56 which in turn terminates in a downwardly directed prong Bl, which prong is as clearly shown in Figure 8 inclined outwardly and downwardly from the main shank portion. The fastener is rigidly engaged with the post by inserting the T-shaped head through the round hole 50 and moving the entire assembly downwardly along the slot 52. With this form it is also preferable to remove a portion of the tongue and main board as at 60 in order that the upper surface of the main shank portion will be substantially flush with the base of the tongue. This form of fastener will be engaged with the board in identically the same manner as the fastener of Figure 1, namely, by driving the same downwardly into the board with the inclined prong acting to pull the board inwardly against the post or othe framing member.

Figures 9 and 10 show .a slight modification of the fastener just described in connection with Figures 7 and 8, the difference residing in the manner in which the inner end portion of the fastener is engaged with the web of the side post. In this form the web of the side post is provided with a simple slot 56 of such length as to readily receive the inner portion 68 of the fastener. This fastener, like that just described, has an outwardly inclined prong portion 10 and main shank portion I2 terminating in a short shank portion 14 adapted to engage the web of the post and be held therein by the integral angular portion 68 previously mentioned. This fastener will be engaged in the post slot by placing the portion 68 vertical and inserting the same through the slot of the post after which the fastener may be rotated through ninety degrees and driven into the lining board which has been suitably formed with a slight cut out portion 16.

In some instances it may" be desirable to use ship lap or some similar form of lining, but each of these fasteners just described are equally applicable to the ship lap type of lining as they are to the tongue and groove type. This will be clearly understood from a study of Figure 11 in which the fastener illustrated in Figure 1 has been shown as fastening the ship lap type of lining to the post. With this form of lining a. portion 82 of the body of the board is removed adjacent the flange 84 and the same'treatment will be necessary or advisable with each of the other types of fastener, although it is obvious that it may be more advantageous to remove a portion of the lining flange in order to permit its correct engagement over the fastener.

In each of the types of fasteners described it will be seen that the prong is so positioned or has a surface so positioned as to draw the lining boards tightly against the metallic framing element to which the fastener is removably secured, this tightening or drawing action taking place during the driving of the fastener to its final position. The fastener has been illustrated as engaging only one edge of the lining board with the opposite edge being retained in position by means of the flange or tongue on the next adianect board, but it is obvious that if desired addi-- tional prongs may be provided permitting the fastener to engage both boards to secure the same in position independently of the flange or tongue.

While the invention has been described more or less in detail it is obvious that various modifications other than those described and mentioned will be suggested to persons skilled in the art and all such modifications are contemplated as fall within the scope of the following claims.
