TIGHTENING MEANS FOR CAB SIDES.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Appllcafion and December 1909. Serial No. 532,609.

To all whom it via y concern:

Be it- .known that I, Gunman F. MURRAY,

.a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useinl Improvements in Tightening Means tor Car Sides, of which the following is a specisame closed at all tunes.

A number of embodiments of the invention have been illustrated in detail in the accompanying drawings forming a part of this specification, and throughout the various views of which like reference characters refer to the same parts, and in these drawin s,

l igure l is a fragmentary elevation of a railway-car equipped with one style or form.

of my joint-closing means; Fig. 2 is a vertical cross-section of the car illustrated in Fig. 1; Fig. 3 is a partial section and partial elevation on the inside of the car near the top thereof; illustrating .on an enlarged scale the means for cloning the joints; Fig. 4 is a cross section through the structure shown in Fig. 3, on line -1-l; Fig. 5 illustrates in section the manner of attaching the boards constituting the side or end ofthe car to the stakes or posts'in such a manner that the shrinkage may be compensated for; Fig. 6

- shows in perspective a modified joint-closing means; Fig. 7 1s a cross section ofthe construction shown in Fig. 6, on line 7-7; Fim

tightening means; Fig. 9 is a cross section through the same on line 9-4701 Fig. 8;

and Fig. 10 is a view similar to Fig. 8, of

still another modification.

The car shown has the usual channel center-sills 20, 20, and bellied, channel side-

sills

21, 21, to'which the lower ends of vertical metallic 22 and 23 are riveted or otherwise secured, the lower ends of diagonal braces 24 being also fastened. to such sills. v t their upper ends these posts and braces are attached to the outer faces of the webs ct channel roof-beams 25 having their top and bottom flanges inwardly extended. as shown clearly in Figs. 2 and 4. The boards or planks 26 forming the car-body wall are bolted, as at 27 (Fig. 5), to the flanges of the posts and braces, the latter being slotted,

permit of the tightening hereinafter described. In the particular embodiment illustrated in Figs. 1 to' 5, inclusive, the bottom flange of each roof-beam 25 has riveted or otherwise secured thereto an inverted Ushaped apron or shield 29 straddling the top board .otthe series formin the car-body side-wall. Such top boar characterized 26?, has fastenedthereto at intervals in any approved manner a as at 28, so as to lurality of wedges 30, and above such edges are cooperating wedge-blocks. 31 pinned at 32 or otherwise secured to a longitudinal bolt or rod 33 extended through the end walls of the car and with a threaded section 3- on which is a end wall are interposed one or more washers 36. As I have illustrated and shown particularly in Figs. 3 and -l, these wedges" and wedge blocks are housed within the U- shaped shield'29 and disposed between the provided'at each end tightening nut 35, between-which and the top edge of the upper board 26 and the channel or roof-beam 25, the constructions of the two side walls of the car being identical.

Assuming that the boards or planks constituting the walls of shrunk so that the joints or seams between the same have opened up and that itis desirable to close the latter, the bolts 27 are loosened so as to permit shifting of the boards or plaiiks relative to the posts and braces. Then the nut 35 at one end of the car is loosened or turned back, whilethe corresponding nut 35 at he other end of the car is tightened up, whereby through means of the connecting rod 33 to draw the wedgeblocks simultaneously in such a direction that their coaction with the wedges 3O fastened to the top board or plank 26 will cause a considerable pressure on the latter,

/ forcing the same and the other boards below it downwardly and closing, up all of they the car-body have i of course, that this movementof the boards or planks is permitted because of the slotted relation between the bolts 27 and the flanges l of the posts or inclined braces, and as soon as these joints or scams have been closed in the manner indicated, the nuts of the bolts 27 are again tightened so as to hold and maintain these boards in their new positions, with all the seams or joints closed.

It should be apparent and. obvious from the illustration and above description of the device and its operation thatthe joints are closed throughout the entire length of the car, due to the simultaneous shifting of a plurality of wedge-blocks coiiperating with the inclined faces of wedges heldin cot peratire relation with the boards or planks. It wlll be furthermore apparent that, dlstor- (ion or displacement of the rod 33 1S prevented by reason of the factthat the top 5 surfaces of the wedge-blocks 31, by sliding on the central or connecting portion of the U-shaped apron 29, transmit the pressure,

tending to raise such blocks directly to the channel roof-beams 25, which are well able to withstand the same, and it is for this reason that this wedge-tightening means is interposed between these roof-beams and the wall boards.

Instead of operating all of the wedges at. the same time, they may be capable of individual actuation, and in Figs. 6 and 7 a somewhat modified construction is illustrated. In this case the bottom flange of the "channel roof-beam 40 is slit at intervals transversely at ll-and longitudinally for a desirable distance at the junction of the fiangewith thereof-beam web, and these sections are then bent so as to provide the vertical portions 42 and the horizontal cars 43, the latter lying against the innerface of the roof-beau; top flange, and being riveted thereto. The top board or plank 26 has fastened thereto at intervals corresponding to and occupying the spaces provided by such bending of the flange sections, a plurality of wedges 44, and above each of these wedges, between its top inclined surface and the upper flange of the roofbeam, I interpose a slidable wedge-block 45 having secured thereto a threaded rod or shank 46 extending longitudinally of the beam 40 through an aperture in the part 42 of the upturned flange, and the (protruding portion 0 the space between the top board and the roof-beam, I rivet to the outer face of the latters web 8. depending metallic plate or apron 48, which prevents the entrance of dirt, moisture and the like from tne. exterior to the inside of the can By reference now to Figs. 8 and 9, it will for each wedge-block, I employ between the top board and the bottom flange of the roofbeam a pair of wedges 49 and 50 bearing against the roof-beam and top board, respectively, as illustrated. Between their diverging faces I interpose a wedge-block 51, the two active faces of which are divergent, as indicated. The small end of this wedgeblock has fastened thereto a threaded rod 52, which passes through an apertured plate or large washer 53 overlying the ends of the two wedges 49 and 50, and I supply the protruding end of such threaded rod with an actuating nut 54. By turning such nut, the wedge block 51 may be drawn inwardly E between the wedges 49 and50 so as to force the wedge 50 downwardly,- pressing the edgeto-edge disposed boards in the same direction and closing all open joints and scams. As in the previous instance, a number of such joint-closing wedge means would be employed at proper points throughout the length of the car. In this instance it is not necessary to fasten the wedges 49 and 59 to the parts against which they bear, since they are etl' ctivcly locked in position by the inteiiposed wedge and the plate or block 53.

eferring now to Fig. 10, another style of independently operated wedge construction is shown. I have supplied the top board and the roof-beam with the

same reference characters

26 and 40 as in the previous instance, and have also illustrated the apron or cover plate 48. Between the parts 40 and 26 I interpose a wed e 60 bearing against the bottom surface 0? the roof-beam, and a wedge-block 61 restin on the top .face of the upper board 26, their inclined active surfaces bearing upon one another, as is clearly shown. The upper wedge-block has at its large end a depending ear or lug 62 apertured for the passage therethrough of the threaded stem or shank 63 secured to the wedge-block 61, the latter, as in all previous instancm, having a. nut- 64 on the same and adapted to abut. against the lug 62. By turning such nut and permitting the same to press against such ear, the wedge-block 61 may be drawn forwardly, thereby pressing downwardly the board 26 and those below it.

To those skilled in the art a number of desirable embodiments of the invention will doubtless occur, after the heart and essence of the invention are understood from this description, and it will therefore be 'madily 4 H P 7 a appreciated thatthis invention is not limited and restricted to the precise structures shown and described. because their mechanical features may be considerably varied withoutthe loss of any of the advantages and benefits accruing from the invention.
