IMPROVED TRACE-FASTEN IN G.

The Schedule referred to inl these Letters Patent and mak-ing part of the same.

To all whom 'it 'may concern:

Be it known that we, WILLIAM W. MALLERY and CHARLES H. SAGE, of Copenhagen, in the county of Lewis, and State of New York, have invented a new and useful Improvement in Trace-Fastening; and we do hereby declare that the'following is a full, clear,

and exactflescription thereof, which'will enable others Figure 2 is a section of tig. 1, through the line x x,

'showing the .fasteningas when applied to a whiffletree.

Similar letters of reference indicate corresponding parts.

This istening-device-is applied by means of two plates, A and B, which are recessed ont for receiving the spring and slide, and the end of the trace. These parts are .duplicates of each other, placed upon the trace so that each part contains half of the trace and half the slide.

In iig. 1, C represents the trace, which is secured to the plates by screws or rivets, as seen at d.

E represents the fastening-slide, which is inclosed in the case formed by the two parts A and B, which case is marked F.

-The case has two slot-holes passing through it. One of these holes, G, near the end of the ease, has its outer end rounded, so that it will lit the whiiietree, and this end of the case receives the draught,

the case being passed over the end of the whietree, as seen in iig. 2. Y

H is the flange or head on the end of the whilletree, which holds the case from slipping off.

The slide E has a stem, I, `around which there is a spiral spring, J.

On the end of the stem I there is a T- cap, K, which passes through each part of the case, as seen in fig. 2, in the slot-hole L. The slide is operated or drawn back by means of this cap, in attaching the trace to the whifletree, and in removing it therefrom.l

rlhe spiral spring leans against the back end of the slide and against the bridge nl, at the end of the hole L, with a const-ant pressure, so that when the slide is drawn back, the reaction ot' the spring forcesit for-V ward, and in contact wit-h the draught-journal of the whiflietree. The tension of the spring keeps the whiiletree at all times in close Contact with the case, and asl there is no forward pressure on the endsrof the whifiietree, the spring-slide renders the fastening complete, and perfectly safe and reliable. The advantages of this arrangement are many, and must be obvious to all.

fe are aware that spring-catches on trace-tasteners are not new, the object being to prevent the traces from being slipped off by a jolt or slaekening thereof; and we wish, therefore, to disclaim the same; but

What we esteem as of our invention, and desire to protect by Letters Patent, is

A trace-fastener, covered on the outside with a smooth-surfaced flame, made in detachable sections, and having a recess to receive the trace, and provided with a forked spring-catch on the inside, all as shown and described. l
