Letters Patent No. 108,282, dated October 11, 1870.
MOO--w IMPROVEMENT IN KING-BOLTS.
The Schedule referred to in these Letters Patent and making part of the Same.
To all whom it may concern.'
Bc it known that I, Farmers l5. Mense, ot' llants v1lle,in the county of Hartford and Stato oi' Connecticut, have invented a new improvement in King- Figure 3, a side view of the bolt without the col-A lar; and in Figure 4, the collar detached.
This invention relates to an improvement in the article of manufacture known to the trade as kingbolts; that is, thc bolt which forms the pivot for the turning of the forward axle.
1n king-bolts as heretofore inaluiiitctured, it has been necessary to form a collar on the bolt, at a little distance above the end of' the clip, for the reason that, in the process of forging, it was difficult, 'if not impossible, to make the bolt as full or large at the baseof the bolt, where it joins the clip, as at a short distance above, a portion of thc metal of the bolt being taken away in finishing the base or neck; but the employment of the V-shaped dies for which a patent was granted to me February 22, 1870, the base or neck of the bolt may be made full,and so as to be ot' regular taper, or diminishing in diameter from the base up.
In the employment of a collar a diiiiculty exists, which arises from the fact that the constant wear upon thc fifth wheel, in consequence of 'its large diameter, is much greater than that on the bolt; consequently, after a little use, the bearing comes on the holt, and is so far taken from the fifth wheel as to make tho hearing unsteady; that is, to tip to one side or the other on the bolt.
The collar is only necessary where the neck of the colt is contracted or made smaller, as I have before referred to, for when the bolt can be made of an increasing diameter from the point to the upper end of the base, and its bearing made accordingly, the wear of the fifth wheel will let thc bearing down on the bolt, insuringr always a constant fit.
The first part of my invention consists in the coustruction ofthe bolt with blanches or parts of the clip formed thereon, the holt oi' an. increased diameter from the intersection of the clip toward the point.
In the employment of a collar or shoulder on the bolt, it must be out or fitted so as to correspond to ihnA fifth wheel.
To thus fit the collar, when formed upon the bolt, as was formerly the custom, the bolt must be set upon the axle and the parts set together, then removed and turned on until the exact height is attained.
To avoid this dili'culty in adjustment, I have herctoiore fitted the collar so as to screw onto the base or neck of the bolt, as seen in the patent granted to me February 28, 1869, for king-bolts; but the ontting of the thread and tapping of the bolt does not avoid'the necessary removal ot the collar-.for adjustment.
To avoid this diiiiculty is the second part of my invention, which consists in combining with a kingbolt, made tapering, or ot' an increasing diameter toward the base, a collar of ductile metal, as brass, bored out to correspond to the taper of the bolt, and so as to be driven down onto the bolt until the required adjustment is attained, the ductility of the metal allowing it to be so driven.
.Previous to the V-shaped dies, to which I have beforc referred,l the ends of the clip were left in the rough and not blanked in any portion, the consumer having been required to forge and work the parts'into shape. By those dies I form the face of the clip, as in figs. 4 and 5, so that up to the broken line the clip is finished, and the consumer has only to round the. end from that point to receive the bolt, the dying out of the bolt from the clip, so as to form a neat and tasteful finish, being produced in the dies.
B is the bol-t. l V
a a, the two parts of the clip, as seen in fig. 3, bcing an extension of the bolt.
By the process ot' forging by means of the V- shaped dies, before referred to, the neck or base at d is enlarged, and from thence toward the point, of a continuous taper or diminishing diameter, as denoted in the drawing.
This bolt is applied in the usual manner, and thc bearing to receive it made of a corresponding form,
so that a perfectt is always insured, and the strongest part ot' the bolt is at the hase, the point of its greatest strain, which, previous to my invention, has been of smaller diameter, necessarily so made in forming the neck.
[n such bolts, it' it is desired to use a collar, and also in bolts of common construction where a collar is required, I construct a collar, C, of any suitable ductile metal, as brass. and bore it out corresponding to the taper of thc bolt, and of thc diameter of the bolt at the highest possible point it may ever be required on tho bolt. Then the consumer, placing the collar upon thc bolt, and the bolt, fifth wheel and parts together, drives the collar down onto the bolt until the required height or adjustment is attained,
the duetility of the metal allowing the collar to be so driven.
The arms a ofl the clip are, by the dies before referred to, forged into shape, as seen in figs. 4 and 5, the `outer surface being finished; the tapering part or raised surface above the broken lille represents the continuation of the end of the clip, when forged to receive the olip-bur and nut,- and the dousurner has only to beat the tip end of the arms, 'and iu suitable dies strike that portion b'elow the broken line into form to receive' the' clip-bar and nuts, avoiding the finishing of the surface, as heretofore required. Y
I claim as my invention 1. The king-bolt B, with the clip-arms a, when the said bolt is `of a decreasingv diameter from its intersection with the clip-arms toward thepoint. substantially as set forth.
' 2.' In combination with the bolt B, the collar G, of suitable metal, so that the collar may be forced on the bolt for the purpose of adjustment, the metal yielding for suoli purpose, substantially in the manner and for the purpose set fort-h.
