IMPROVEMENT IN CARRIAGE-THILL ATTACHMENTS.

Specification formingpart of Letters Patent No. 27,110, dated February 14, 1860.

To all whom it may concern:

Be it known that I, HENRY E. CLINTON, of

V the town of \Voodbridge, county of New Haven, and State of Connecticut, have invented a new and Improved Mode of Coupling Carriage-Shafts to the Shaft-Jack; and I do hereby declare that the following is a full and exact description.

The nature of my invention consists in constructing the shaft-eye so as to hook onto the jack-bolt, and is secured in its place by means of a spring-key, thus doing away with the nut and screw which are now in use.

To enable others skilled in the artto make and use my invention, I will proceed to describe its construction and operation, and reference is made to the accompanying drawings, and letters marked thereon, as part of this specification.

I construct the shaft-jack A of iron or steel, and leave the slot II of sufficient Width to admit the shaft-eye C. I weld the jack-bolt or pivot E firmly in its place, as shown at E E, Figure 4, and leave space enough between the bolt and the back of the slot to admit the shaft-eye C, and also the spring-key B. The shaft-jack is attached to the axle-tree G by any of the known ways. The shaft F, I construct in the usual modes, and make the shaft-eye C in the form of a hook, so as to clasp the jack-bolt E, as shown at C C, Fig. 2. I make the key B of any suitable material with a head, and curve the side of the key which rests against the shaft-eye, so as to conform to the turn or curve of the shaft-eye, as shown at I, Figs. 2 and 3. I then cut the slot'J for the spring D to act in, as shown at Fig. 2. I attach the spring to the back of the key, as shown at K, Fig. 5. This spring is turned outward at right angles, so as to form a shoulder which rests again st the under side of the jack and prevents the key from getting out of place, as shown at L, Fig. 2. The lower end of the spring is turned inward toward the slot. I couple the shaft to the jackbolt by removing the spring-keys and adj usting the shaft-eyes to the jack-bolts. The keys are then forced into the slots and hold the shafts firmly in place. I detach or uncouple the shaft by removing the spring-keys.

What I claim as my invention, and desire to secureby Letters Patent, is-

The application of the spring-key 13, substan tially and for the purposes as is herein set forth.

HENRY E. CLINTON.
