IMPROVEMENT IN GBOLT.

The Schedule referred to in theseV Letters Patent and making part of the sama.

To all whom itmwy concern Be it known that I, F. B. MORSE, of New Haven,

' in 'the county of New Haven, and State of Connecticut,

have invented a newlmprovement in King-Bolt for Oarriag'es; and I .do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitutepart of thisspecification, and represent, in

Figure 1, a side view of the bolt complete;

Figure 2, the bolt detached from the neck; and in Figure 3, the neck separated from the bolt.

This invention relates to an improvement in the article of manufacture known to the trade as king' bolts; thatis, the bolt which forms the pivot for theA turning of the forward axle.

Heretofore these have been forged in a single piece, the neckl forged on.

The two prongs lare left as seen in iig. 1, and thev consumer forgesthem tothe proper shape to form a' clip around the axle, and so as to be secured thereto in the usual manner of securing carriage-clips.

The bolt is rst fitted to the axle, and then the parts set together.

It is necessary that, when the parts are so set together, the neck should come to a bearing-at the same time that the fifth-wheel bears, and as this is liable'to variation, it' is necessary to adjust the bolt tothe fthwheel, and this has heretofore been done, either by drawing the bolt at the neck, if too short, or ling from the upper side of the neck, if too long. This ynecessitates the taking of the bolt from the axle to bealtered and replaced. Thus it is sometimes necessary to remove the king-bolt several times, in order to a perfect adjustment, which causes no inconsiderable labor, toA

ner, and at its base, e, I cut a thread, as seen in fig. 2.

The neck, B, I make of any convenient external form, as seen in tig. 3,and tap it to correspond to the thread on the bolt, so that it may be turned freely thereonfas seen in' iig. 1, making the neck sufciently long, that it 'will be at least high enough for any purpose, .and the bolt is complete and ready for market.

When theconsumer has fixed the bolt to the axle in the usual manner, he' places the parts together, and if found toohigh, removes the neck, and cuts it down to the required height. The removing of the neck, and convenience of cutting that down, in comparison with the old method of vremoving the bolt, it will be readily seen, simplifies the adjustment of the bolt to. a very great extent.

, Having fully described myinvention, V What I claim as new and useful, and desire to secure by Letters Patent, is-

A kingfbolt, constructed with the detachable neck B, substantially in the manner described, aslau improved article of manufacture.

E. B. MORSE.
