. As shown in, Figs. 2" and 3 the underfran'ieof the car comprises a center sill fland side sills 35, The depressed or overlapped parts K were connected to the body" parts of the sheets" '26 by inclined webs" 3F. A member 39, preferably comprising a strip, overlies the overlapped parts 36'- of the sheets 26 and has itsedges If beveled complementary to the inclined wees'ae orthe sheets 26. The upper surface 42 of the member 39 is preferably flush with the body parts of the sheets 26 and the member 39 is tightly secured to the wooden floor 23 by bolts 44 having countersunk heads. The bolts 44 may extend only through the wooden floor 23, as shown in Fig. 5, or may extend in addition through parts of the underframe ID of the car.
Fig. 6 shows a section at the extreme edge of the floor protecting covering 25. The edge 49 of the single sheet 50 is depressed in a manner similar to that shown in Fig. and a similar beveled strip 39 overlies the depressed part 49 of the sheet. Bolts 44 as heretoforedescribed extend through the strip 39 and wooden 'floor'23 and clamp the edge of the sheet 50.
Fig. 9 shows a modified means of securing the floor protecting covering 25 to the'wooden floor 23, The sheet 59 is formed with a depending flange 52 which is disposed in a groove 53 in the wooden floor 23. Bolts 54 having countersunk heads secure the sheet 59 to the wooden floor 23. In the modification shown in Fig. 8, the ad jacent edges 55 of the sheets 56 abut rather than overlap. The depressed parts 58 are connected'to the body parts of the sheets 56 by inclined webs 59, as heretofore described, and the usual beveled strip 39 overlies the depressed parts 58 of'the sheets. In this case, notches are provided in the edges 55 of the she'ets56 to'accommodate the bolts 44 inp'lace of the holes provided in the depressed parts of the sheets shown in Fig. 5.
The wood used in the wooden'floors of cars of this type is commonly of a relatively soft type. Heavy loads are hauled in on truckshaving wheels of small diameter and such wheels squeeze the body part of the sheet into the wooden floor with consequent upcurling'of the edges unless such edges are securely clamped. As shown in Fig. 5 particularly, the beveled edges 4| of the'strip 39 are in contact with the inclined webs 38 of the sheets 26 over relatively small areas at the upper parts ofthe web 38. The overlapped parts 36 of the sheets 26 are securely fastened by being clamped between the strip 39 and the wood floor 23. The marginal portionof each sheet'26 is thus fastened at two spaced apart places; i. e., at the webs 38 and the overlapped parts 36. As hereinabove pointed out, the rolling of heavily loaded wheels over the floor tends to curl the edges of the sheets upwardly, ,Such curling is resisted, in part,iby the strip. 39 partially overlying the webs 38 and bythe contact areas between the strip 39 and webs 38 being positioned substantially at the level ,of the body-parts of the sheets 26. The possibility is thuselirninated that the marginal parts of the sheetsZB might straighten out or otherwisefdeform'and thereby permit curling ofthe sheets. 5 I
It is evident from Fig. 5 that each of the over-. lapped parts 36 is provided with holes through which the bolts 44'are inserted. When, the bolts 44 are tightened, the strip 39 forces the right hand sheet 26ytowardthe right and the. left hand sheet 26:toward the left preferably as far as permitted by the clearance between the bolts 44 and saidholes. Atightly interlocked joint is thus formed to resist upcurling of the sheets 26.
The accompanying drawings illustrate the preferred; form of the invention, though it is to be understood that the invention isnot limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur topersons skilled in the art.
