. My present invention relates to railway cars for transporting logs and it has for an ob-' ject to provide certain new-and useful appli-' ances which will enable the use'of the present well known Simplex bolster along with the arch bar truck inlogging car structure. Furthen-the invention has for its object to provide an outside friction which may be applied to the bolster without changing the construction thereof and which will not interfere with the proper functioning ofeither the bolster, the truck or the cushioning springs. 3

Other objects will in part be obvious and in part bepointed out hereinafter.

To the attainment of the aforesaid objects and ends, the invention still further resides in the novel details of construc'tiomcombination and arrangement of parts, all of which will be first fully'described in the following detailed description, then be particularly pointed out in the appended claims, reference being had to the accompanying draws ing's, in which Figure; 1 isa side elevation of a portion of a logging car with my invention, the truck being indicated in dotted lines; I

The truck bolster 1 is formed of an" inverted U channel beam, the .top surface of'which inclines dow-nwardly, as ate," and' 1 outwardly from the center to a point beneath the arch bar 43 of the truck side frame, from whence it inclines upwardly to the end of the beam as atl5.

Thestrengthening'iron is indicated by 6 and this iron is secured at the center 7 and has its ends turned over the ends of the bolster beam to which it is securely riveted as at 9, there being filler members 10 provided for I The construction of the truck bolster is that of the well known Simplex bolster and per se is not-of my invention.

Secured to the outer ends of the bolster are outside frictions, each of which comprises acasting consisting of a base part ;11' from which depend. an inside flange 12, an outside flange 13, and front and back flange plates'll,

the latter having riveting holes 15 hereinafter again referred to.

16 is the rubb'ng head of the outer friction, which head is connected to the base part 11 o by

suitable webs

several flanges

In mounting the outer friction on the projecting end of the truck bolster the outer rivet which secures thesheathing 44: that has the truckframe guideways, to the bolster is re- .moved. This rivet is replaced by a new one "which also passes through the apertures 15 and serves to secure the flange plates 14 to the sides of the bolster. r 21 designates the longitudinal body beams (usuallyjof wood) of, the car, thesebeams being secured together side by side by suitable bolts e6, which also serve to secure the bol; ster mounting plates 22 in place.

The body bolster consists of laterally projecting Li-irons 2a, to theinner endsof which are-riveted angle irons 25,- the latter being The body center plate 3 is secured .to

36 is the inner friction casting whose base 37 is riveted at 38 to the truck bolster 1. The inner friction 36 has its friction head con nected to the base 37 by suitable webs 39.

The inner friction block 30 may be of the same construction as the friction block 28 and it may be secured to the body bolster in a similar manner as byv the use of angles 41 riveted to the block 40 and to the bolster irons 24. i i n 42 designates the truck side frame, the arch bar .43 of which overlies the truck bolster at about the lowest point of the dip of the upper face thereof and the side frame 42 is thus located in a plane between the inner and outer frictions. The inner friction may be dispensed with if desired.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be clear to those skilled in the art to which it relates.

What I claim is:
