can-noon.

Be it known that I, Wan'rnn, P. MURPHY,

a citizen of the United States, and a resident of Chicago, county of Cook, State of Illinois, have invented a newa'nd useful Imrovement in Car-Roofs, of which the folowing is a specification.

ThlS invention relates to car roofs and more particularly to the carlines for supporting the same.

It has for its principal objects to take up looseness due to the shrinkage of the wooden sideplates or longitudinal timbersto-which the. ends of the carlines are secured, and to attain certain advantages hereinafter more fully appearing. 1

The invention consists in the parts and in thearrangements and combinations of parts hereinafter described and claimed. y In the accompanying drawings, forming part of this specification, and wherein like -.symbol s refer to like parts-wherever they occur, Figure 1 is a fragmentary cross'section through the side plate of. scar adjacent to a carline, illustrating anada tation' ofmy I invention; Fig. 2 is a viewpart y in top plan amlpartlyin horizontal section on theline 2- 2 of Fig. 1; Fig. 3 is a viewpartly in elekation and partly in vertical section' on the 'ine 3'3 of Fi 1; Fig. 4 isl-a'perspective view'ot' the tig tening wedge and locking member detached; Fig. 5 is'a view partly in elevation and partly in verticalsection showing a modification of the locking memher for the tightening wedge; Fig.6 is a fragmentary cross section through the sideplate of a car' adjacent to a carline, illustrating a modification of the ti h tenin wedge; Fig. 7 is a section on the me 7- of Fi 6; and, Fig. 8 is a fragmentary section s owing a; further modification of the I tightening wedge.

The carline shown in'the drawings comprises a metal angle member 1 having se cured thereon a wooden filler or beam 2, to

which the roof superstructure is fastcn'ed' "Obviously, however, the carline maybe of any other desirable construct-ion. 'Ilhe ends of the angle member I are connected to the side plates 3 by a saddle memspecificetion of Letters latent. Patented M131. 1,1910. Application filed June 14, 1909. Serial No. 501,965.

with a downwardly extending bracket portion 5 and a downturned end portion 6 so as fto straddle the side plate 3. The saddle member is provided with an inwardly projectingi bracket 7 of angular section corresponding to the angle member 1 to which it her or casting'4. This member isprovided 1s riveted or'otherwise-rigidly secured. The

portion 5 is provided with a depending lug or ear 8 which is perforated to receive a securing bolt 9 extending through the side -plate 3." I

The bracket portion 5 is hollowed out and the lower portions of the side walls 10 are cut away to provide a transverse passageway for a wedge member .11. The outer face of the member 11 is made flat so as to'bear flatwise against the inner face of the side' plate 3 while the inner face is inclined or, preferably, it is provided with inclined ribs 12, as shown, which. are adapted to bear against correspondingly inclined horizontal ribs 13 on the outer face of the wall 14 of the bracket portion 5. To prevent the wedge from working out when'it is driven between the side plate and saddle member, the upper side of the wedge is provided with a series of serrations or teeth 15. These are adapted-to engage reversely arranged or counterpart teeth 16 on theunderside of a gravitating block 17 which is fitted loosely in the pocket 18 provided in the portion. 5 of the saddle member above the transverse wedge passageway. By the foregoing arrangement the wedge 11 may be driven until the downturned end portion 6 of the saddle member is drawn tightly against the, outer face of the side plate; The block 17 being fitted loosely in the pocket 18 will rise and fall as the serrated side of the wedge moves thereunder, the block being limited to an almost imperceptible endwise movement by.

theside walls 10.

As shown in Fig. 5, a pawl or dog 19 may be pivotally mounted in the pocket 18 and substituted for. the gravitating block 17 out. In Figs. 6 and 7, the locking wedge 11" is vertically arranged so as'to drop by gravto prevent the tightening wedge-11 from workin ity and the motion of the car and thereby have a tendency to continually and automatically take u all looseness between the side plate and sa dle member. The top side of the wedge piecell is, however, inclined to cooperate with the inclined underside of a cross wedge or key 20. which is slidably fitted in a transverse slideway across the upper portion of the saddle member. Preferably, the wedge 20 1 provided with a llOl'lZOIllfil rib 21 extending lengthwise of its up er-mner edge and fitting in a groove grow ed therefor in the saddle member.

y this arrangement, the cross wedge 20. may be readily driven'forwardly to force the wedge 11' downwardly. The rib 21 will support the cross wed e 20 and prevent it from sliding out of the s ideway when the wedge 11 drops by its own wei ht and the motion of the car should, any ooseness or play occur between the side plate and saddle member after the parts have been tightened by driving the cross wedge 20.

In Fig. 8 a gravitating Tightening wedge 11 is shown. In this modification a screwthreaded stud or projection 22 is provided on the lower end of the wedge. The stud 22 projectsthrough a slot 23 in the bottom wall 24 of the bracket extension 5 of the saddle'member and it is provided with a nut 25 which bears against said bottom wall whereby the wedge may be drawn downwardly and heldin tightenedposition. The saddle members shown in Figs. 6 to 8, inclusive, are provided with lateral ears or lugs 26 in lieu of the depending lugs 8 of the other modifications.

By the construction and arrangements shown, the carlines may be rigidly connected with the side lates when the car is built, and should any ooseness later occur due to the shrinkage of the side plates and rough usage of the car, the wedges can be readily tightened to maintain the rigidity of the roof structure. Thus, the many isadvantages due to looseness of the connections are obviated.

Obviously ment admlts of considerable modification without departing from my invention. Therefore, I do not wish to be limited to the specific construction and arrangements shown. t
