- IMPROVEMENT m CARRIAGE-curs;

The Schedule referred to in tliese Letters I'atent and making part of the same.

.To all whom it may concern Be it known that I, FRAxcIs B. Mouse, of Plants- -ville,-in the county of Hartford and State of Gonnecticut, have invented a new Improvement in Carriage- Clips; and I do hereby declare the following, when taken inconnection with the accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and

' which said drawing constitutes part of this specification, and represents in-' Figure 1, a top view;

Figure 2, a transverse section of the clip after trimrning; I v

Figure 3, atra'nsverse section as finished; and in "Figure 4, a transverse sectionof an oval clip.

This invention relates to an improvement in carriage-clips.

' 1n the manufacture of carriage-clips, after the clip has been formed it is placed in the trimming-die and the fin around the body of the clip is cut away, leaving a comparatively thick edge, and often rough, the trimming being the last process except what may be done by hand.

The object of my invention is to finish the edge of the clip after it comes from the trimming-die; and

It consists in bringing the edge of the clip, from shank to shank, down to a thin, sharp edge by striking it in dies prepared for the purpose after the trimming operation.

A is the body of the clip.

B B, the two shanks.

As heretofore formed, the body of the clip has been "made of an equal thickness and trimmed, leaving it in transverse section, as seen-in fig. 2. This edge hassometimes been filed away. over the central 'po'rtiou'of the clip, but only in the very best of work, as the expense of so doing is too great.

To finish the clip, I prepare adieof the form of the clip, with a chamfered edge from shank to shank, the

impres'sion'in the die being'a little wider' than the trimmed clip; then place the trimmed clip, heated.- simply to a dark-red heat, not enough to form a scale, into the die, and strike it therein by a follower in the usual manner, and the edge is chamfered corresponding to the die, as seen in fig. 3, from shank to shank, as seen in fig. 1, finishing the clip to a sharp edge.

If an ovalclip is preferred, as seenin transverse section, fig. 4, the die is prepared accordingly, and the clip, as it comes from the trimming-die, is again struck,

as described for the chamfered edge, the oval surface shank to shank, after the clip has been trimmed,sub-

stantially as and for the purpose set forth.

F. B. MORSE.
