removing the bolster or withdrawingthe bolts that hold the draft-timbers in place.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a perspective view of my improved bolster with the center bearing detached. Fig. II is a side view part in vertical Fig. III is a transverse section taken on line III III, Fig. II.

1 represents a cast bolster which, as I have shown, is of the I-beam form in cross-section; but this shape is not essential to my inven- The lower central part of the bolster is formed with recesses 2 to receive the drafttimbers 3 of the rigging, and the lower middle part 4 of the bolster is made ina separate piece and is set into the body, as shown clearly in Fig. II. This removable part or plate carries the center bearing 5, and its upper face is provided with a stud 6, that fits in a socket 7 formed in the middle part 8 of the body of the bolster. This stud, together with the fact that the plate fits up against the part 8 of the bolster and between the faces 9, forms a secure union between the plate and the body when the bolts 10 are applied.

When it is necessary to renew the drafttimbers, they can be taken out by simply removing the nuts from the bolts 10. The plate 4: and draft-timbers can then he slipped downwardly on the bolts. New timbers can then be inserted and the plate and nuts replaced, the operation being performed without'having to remove the bolts, thing to do.
