JOHN A. J. SAWYER, OF LYNN, MASSACHUSETTS.
IMPROVEMENT IN CARRIAGE-SHAFTS.
Specification forming part of Letters Patent N 0. 189,657, dated April 17, 1877 application filed March 13, 1877.
To all whom it may concern:
Be it known that I, JOHN A. J. SAWYER,
with my invention.
In making carriage-shafts it is customary to first steam the wood, and while it is in such condition to bend it into shape. A shaft sov made is very liable in course of use to straighten more or less at the bent parts. One object of my invention is to prevent this, another being to greatly strengthen the shaft in the portion which is to project beyond the tug of the saddle of the harness.
In carrying out my invention I insert within the wooden shaft A lengthwise of it from its lesser end a strip, B, of metal, it being extended throughout the curved part, which it may be desirable to strengthen. This strip I secure in place by a series of rivets, a a, going through it and the shaft. Furthermore, the strip or re-enforoe is provided with short flanges b b, arranged to project from it at intervals, and at its upper and lower edges, or
they may be continued from end to end of it. In the drawings these flanges are shown as arranged over rivets, such an arrangement serving to there strengthen the shaft when weakened by the rivet-holes.
The strip or re-enforce extends lengthwise within the thimble or'ferrule O, and thereby serves to prevent such from being broken off the shaft by a horse stepping on the shaft or the ferrule. The re-enforce also prevents the shaft from being broken when stepped on by a horse as it is very liable to be when without the re enforce.
I do not claim a whiffletree or evener-bar, having a metal plate arranged lengthwise within it, or between its layers of wood.
What I claim is 1. The combination of a wooden carriageshaft, A, and a metallic strip or re-enforce, B, arranged therein, and fastened thereto, and provided with flanges, as set forth.
2. The combination of a wooden carriageshaft, A, and its metallic thimble or ferrule C, with a metallic strip or re-enforce, B, provided with flanges, and arranged within such shaft and thimble, and fastened to the shaft by .rivets, all substantially as specified.
