'SHACKLE-IRON FOR WHIFFLETREES.

SPECIFICATION forming part of Letters Patent No. 251,140, dated December 20, 1881.

Application filed September 17, 1881. (ModeL) To all whom it may concern Be it known that I, WILLIAM R. ScoFrELD, of De Wittville, in the county of Chautauqua and State of New York, have invented a new and useful Improvement in Shackle Irons for Whifflctrees; and I do hereby declare the. the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

Figure 1 represents my improvement attached to the end of a whiflietree. Fig. 2 is a transverse section of the same, taken at linear aof Fig. 1'. Fig. 3 represents acentrallongitudinal section of the detachable hinge-connection, taken at line 3 y. Fig. 4. represents the D-shaped hinge-connection and ferrule or socket as attached to the center of a whiffletree.

Myimprovementrelatesto the mannerofconstructing and connecting the partsof shackleirons for whiffletrees, and provides the means for readily removing a worn and weak part and substituting a new part without mechanical aid or assistance, as hereinafter described.

Shackleirons for whifiletrees are usually forged and welded, the D-shaped loop I) being made as a part of ferrule 13. The chain or trace book being connected ith loop D, as seen in Fig.1, by constant abrasion causes loop D to be worn away, so as to be no longer safe for use, whileits ferrule embracing the whiffletree remains unimpaired, and consequently when the loop D and ferrule B are formed as a single piece both must be cast aside and a new mounting substituted, although the ferrule remains perfectly good. Such is also the result from wear of the loop I, connected with the hook, and for this reason I have provided the second small loop, H, which, when it becomes too much worn to be safely used longer,

may be cutoff from loop I and the latter be used in its stead, in connection with anew loop, D. The screw-bolt a and thimble O furnish the means and ready facility of making the substitution above specified, the object of my invention being to utilize all the parts of the shackle until each becomes too much worn to serve the purpose intended.

In the drawings, A denotes the whiffletree; B, the collar or ferrule; O, thethitnble orhingesocket, which is cast with ferrule 13; D, the loop, connected by the hinge-bolt ato thethimbleO; and E isthe hook prov ded with the two loops H I, and as each of the parts-namely, the hook with its two loops, the hinge-loop D, and the ferrule B, with its thimble O-may be cast of malleable iron the shackle-iron is cheapened in construction, and economy is at taiued by the means of supplying a new part for one which has become trail and worthless, without having to cast asidea part still unimpaired.

Havingdescribed my invention. I claim and desire to secure by Letters Patent 1. The combination of the thimble-heating (3, cast as a part of the ferrule B, with the shackle-loop D, substantially as and for the purpose herein specified.

2. The combination of the thimble-bearing 0, cast as a part of the ferrule B, shat-ke-loop D, and the pivot-bolt a, screwed into the bearing 0, substantially as and for the pur; ose herein specified.

3. The combination of the thimble-beating G, removable shackle-loop l),and double loops H I, formed on the hook E, substantially as and for the purpose herein specified.
