IMPROVEMENT IN DETACHING-HOQKS.

v'.ihe Schedule referred to in these Letters Patent and making part of the same.

To all whom. it may concern: v

.Beit known that we, JOSEPH Woon TUTTLE and JULIUs PETERSON, of Rochester, in the county Aof Monroe and State of New York, have jointly invented a certain new and useful Im'prowernent in Disengaging- Hooks, for `use on canal-boats, and other purposes, of which the following is a specification, referring to the accompanying drawings.

' Nature of Invention.

Generai Description. In the drawings- Figure 1 is a side elevation, and Figure 2, a plan.

A is the shank of the hook, having pivoted at one4 end the clevis B, and at the other the hook-armi C.

Between these is also pivoted the swinging catch D, which is preferably in the form oi'a link, and turns up over the end of the hook-'arm to hold itin place, as clearlyshown.` Instead of this form itmay be made of any that will produce the same result.

The hook-arm bends forward in such a manner as to overlie the shank, and the connection of the swingvingcatch with it is such that it may be drawn off to disengage the hookarm.

At the rear end of the device a socket, a, is formed, of suitable 4size and' shav e to receive a loose ring, G.

Thus arranged, the draft-rope H may be attached either to the ring G, as in tig. 1, or to the clevis B, as in fig. 2, the drawings showing the positions reversed for different uses.

In those different uses the cord I, which attaches to the pawl to operate it, also passes in different drec tions, as shown.

In Iig. l1 the hook is shown as adjusted in the position for a person standing at a distance, in thestern wwwof the boat, to disengage the hook. This would be convenient for the steersman.

In fig; 2 it is 'shown as adjusted in the position for the driver to ,disengage the swinging catch, he stand- "ing on the bank of the canal, and a distance forward of the boat.

The essential novelty in this case is the adaptation of the portable hook, as above described, whereby it is applicable to'nse vineither di'ection. On canals, especially, it is of very great advantage, as the power to 'dsengage may be transferred at pleasure from the ste'ersrnan' to the driver, which is frequently desirable inpassing other boats or going upon an unobstructed way. To do this it is only necessary to change ends of the hook.

By its portability and capability of attachment at' either end it also is adapted to many other uses, and may be interposed at anyy position in a continuous chain, an effect which we believe is new. We can also use it as a coupling to uncouplc at will on' any chain or cord subject to strain.

We are aware that in other devices n. swinging catch has before been used to disconnect a part serving as an attachment to a cord or chain.

'We are also aware that a hook-arm for releasing a cord or chain has before been used. Such broadly we do not claim; but

What we claim as our invention is The shank constructed as herein shown and described,

lprovided with a hinged arm, O, swinging catch D, and olevis -B, all combined and arranged as herein shown and described.

In witness whereof we have hereunto signed our names in the. presence of twosubscribingwitnesses.
