Specification of Letters Patent.

`vl atented Ang. 10, 1909.

Application filed August 8, 1908. Serial No` 447,578..

To all whcmr'it may concern:

. Be itknown that I, WALTR P. l'vlUnPI-IY, a citizen of the United States, and a resident of the eityof St. Louis and State of Missouri, have invented a new and useful Improvement in Carslioofs, of which the following is a specication.

This invention relates 'to car lroofs and more particularly to the carlines for support ing,r the same,

It has foritsprincipal objects to take up looseness dueto the. shrinkage of the wooden side plates o1" longitudinal timl ers to which the ends of the carlines are secured, and to overcome certain disadvantages of the usual supporting saddlesor attaching devices of metal carlines. p

In metal carline constructions, it is customary in some cases, to shape the end portions of the carlines to fit over the side plates or longitudinal timbers, and in other cases, the end portions of the car-lines are secured to separate castings or saddle meml ers which are adapted to be fitted over said side plates. In practice, it has been found that such connecting devices become loosened from the wooden side plates or timbers, due

-to the shrinkage thereof.

My invention, therefore, consists in a co1npensating member or Wedge which takes up such looseness, and it further consists in the constructions, combinations and arrangev ments of parts .hereinafter described and claimed.

In the accompanying drawings which form part of this specification, and wherein like symbols refer to like parts Wherever they occur, Figure 1 is an elevation partly in section, showing a portion of a carline embodying my invention; Fig. 2 is a top plan view thereof;. Fig. 3 is a longitudinal section through the end portion of the carline, connecting member and side plate; and Fig. 4 is a detail view of a preferred form of co1npeneating member or wedge.

In the drawings, the carlinecomprises a metal angle member 1 having secured thereon a Wooden filler or` beam 2 to which the roof superstructure is fastened. l Obviously, l however, the carline may be of any other de cars 6 for the reception of scouring),A `bolts 7, whereby, said portion 5 may le secured flat- Wise against the inner face of the side plate 3.v Gn the racket portion 5 is -an inwardly projecting' portion 8 of angular section corresponding to the section of the angle mein ler 1 to which it is rigidly rivetedor secured. The wooden filler member 2 is also secured to the memrer 8 by va lfolt 9 extending through the vertical' flange thereof as well as the intervening' vertical flange of thc ang-lo, meinler l. The end connecting member 4 is also provided with a saddle portion 10 having a downturned outer end portion 11 so as to straddle the side plate 3.

Preferably, the portion 5 of the connecting member 4 is liollowed out and provided with an inclined inner face. 12 so as to acconnnog date an insertible take-up member or wedge 13. Preferably, this wedge is made with a ila't face adapted to lie llatwise against the inner face of the sideplate 3, and an inclined face, or ribs 14, corresponding' to the inclination of the inner face 12 of the portion 5 ofthe end connecting member 4.

In. practice, the wedge 13 is made to fit freely within the pocket provided therefor in the bracket portion 5 of the end connecting member 4, and the angle of the opposinfr in-` clined faces of the Wedge and Yocliet wall being slight, the Wedge will droplliy gravity and the motion of the car, thereby, constantly taking u all looseness due to the shrinka e extending portions 5 and 11 of the end connecting member 4. y Thus, the rigidity of the roof structure' is maintained and many disare overcome.

Obviously, supplemental wedges or other devices may be made to coperate with the single wedge shown, and the device may be otherwise .modified without departing from the invention. Therefore, I do not wish to be limited to the exact construction and arrangement shown.

What I claim is:

1. -A carline or the like comprising a saddle portion arranged to straddle the side platev of a car, and means tending continuously and automatically to take -up looseness between said side plate and said saddle portion.

2. A carline or the.A like comprisingcg` a saddle portion arranged to straddle the side plate of a car, and a compensatinpr clement tendingl of the side plate between. the downward y` advantages due to looseness of connectionsl continuously and automatically to take up looseness between said side plate and said saddle portion.

3. A carline or the lilieco'mprising a saddle portion having downturned members adapted to sti'addle the side plate of a car, one of said downtui'ned members having an incline opposite the face of said side late, and a v counterpart compensating mem er between said incline and the opposing face of said side plate, said compensating member tending continuouslyto take up the space between said incline and said side plate.

4. A carline oi' thc like comprising a saddle portion having downturned members adaptcd to sti'addle the side plate, of a cai', one of said downturned members havinv an incline opposite the face of said side plate, and a movably mounted wedge element one face ol which bears liatwise against said face of the side plate and whose other face bears against said incline, said Wedge element tending' continuously and automatically to take up an)v looscness that may occur between said side. plate and said incline.

5. A cai'line or the like comprising means l'oiconnecting the same to the side plate of a cai, said means comprising a gravitatmg device adapted to constantly take up looseesfeve Ainserted between said incline and t e opposing face of said side plate.

8. A carline or the like comprisin an end connecting member. adapted to e vconnected to the side plate of a car, and a gravitating Wedge to be inserted between said side plate and said end connecting member.

In 'testimony whereof I have hereunto signed my naine in the presence of t'w subscribing witnesses on the 1st day of .August WALTER 1 MURPHY.
