Description

J. M. CHILDS. v FASTENINGS FOR SECTIONAL RATCHE'I' WHEELS. 110.185.0151
Patented Dec. 5. 1876.
ATTORNEYS WITNESSES:
UNITED STATES PATENT FFIGE.
J. MORRIS OHILDS, OF UTIGA, NEW YORK.
IMPROVEMENT IN FASTENINGS FOR SECTIONAL RATCHET-WHEELS.
Specification forming part of Letters Patent No. 185,015, dated December 5, 1876; application filed October 30, 1876.
which my improvement has been applied, the
shaft being shown in section. Fig. 2 is a sec- -tion of the same, the shaft being shown in side view.
Similar letters ofreference indicate corresponding parts.
The object of this invention is to secure a ratchet-wheel to the round shaft of a hay-rake in such a way that it can be put on and taken off without removing the attachments of said shaft, and in such a way that it cannot slip upon the said shaft, and will carry the shaft with it in its revolution.
The invention consists in a ratchet-Wheel fastening formed of the round shaft provided with a squared or flattened portion to receive the ratchet-wheel, and the sectional ratchet-wheel provided with a similarly shaped bore, as hereinafter fully described.
The ratchet-wheel is made in two sections or halves, A B, which are secured to each other and to the shaft 0 by bolts D. The shaft 0 is squaredor flattened for a space equal to the thickness of the ratchet-wheel A B, and the bore of the sectional wheel is made of the same shape, so that said wheel cannot the sudden strain when the ratchet-wheel is thrown into gear, to raise the rake-teeth and discharge the collected hay.
I am aware that ratchet-wheels have been made in sections secured to each other by bolts, and I am also aware that sectional ratchetwheels have been secured to their shafts by keys and pins. These-constructions I do not claim; but,
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- V A ratchet-wheel fastening formed of the round shaft 0, provided with a squared or flattened portion to receivethe ratchet-wheel, and the sectional ratchet-wheel A B, provided with a similarly-shaped bore, substantially as herein shown and described.
