HOOK.

SPECIFICATION forming part of Letters Patent No. 601,240, dated March 29, 1898.

Application filed January 14,1897. Serial No. 619,154. (No model.)

To aZZ whom it may concern.-

Be it known that I, ROBERT ALEXANDER OOACHMAN, a citizen of the United States, residing at Tunica, in the county of Tunica and State of Mississippi, have invented certain new and useful Improvements in I-Iame- Hooks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to harness, the object of the same being to provide a simple and effective means for attaching chain tugs or traces to the hames which will prevent the accidental disconnection of these parts.

The invention consists of a hook pivotally connected to the hame upon a suitable loop or staple, the said hook being made up of a flat bar of metal with a spiral opening in the rear end thereof, in which opening the for ward link of the chain tug or trace is adapted to be passed.

The invention also consists in other details of construction and combinations of parts, which will be hereinafter more fully described and claimed. 1 r

In the drawings forming part of this specification, Figure 1 represents a perspective View of my device shown applied. Fig. 2 is a side elevation of the same with the forward link of the chain tug in place. Fig. 3 is a vertical section through the forward end of the hook and the staple through which said hook is connected to the hame.

Like reference-numerals indicate like parts in the different views.

The collar 1 and the hame 2, connected thereto, are of the usual form'and construction.

The hame-hook 3, in which my invention resides, is made up of a flat bar of metal which is pivoted at its forward end to the loop or staple 4:, as clearly shown. The said loop or staple isrigidly attached to the hame 2, and the outer straight portion thereof passes through an opening 5 in the forward end of the bar 3. The said bar is cut away on its under side, as shown at 6, and its rear end is formed with a spirally-arranged opening 7, in which the forward link 8 of the chain tug or trace is adapted to be inserted. The said opening 7, by reason of its peculiar shape,forms the cycloidal-shaped rib 9,which extends from the upper edge of the bar 3, and the substantially 5 5 circular rib 10, which extends rearwardly and upwardly from the lower edge of said bar. Said ribs 9 and 10 are parallel throughout their entire length, and the inner end of the rib 9 extends across the rear end of the open- 6oing 7,forming an abutting shoulder 9", against which the link 8 may bear in case the latter is forced inwardly. This shoulder, with the knob 11, which is formed upon the end of the rib 9, serves to effectually prevent the detachment of the link 8 from the hook, and by reason of it the opening 7 may be of the same width throughout its entire length, thereby permitting of the ready insertion of the link 8 therein.

As thus constructed the operation of my device is as follows: When it is desired to connect the trace to the hames, the forward link 8 of said trace is passed into the opening 7 at the upper edge of the bar 3 and thence around through the spirally-arranged opening until it is seated between the knob 11 on the inner end of the rib 9 and the inner surface of said rib. When in place, it is next to impossible for said link to become accidentally detached from the hook, as it is necessary in order for the same to be removed from its seat that it be passed around through the spiral opening 7, which movement cannot be accidentally effected. V

The device is extremely simple in construction, and by its use all buckles, snap-hooks, and the like are done away with.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

A hook made up of a bar having a spirallyarranged opening therein of substantially the same width throughout its entire length, form ing substantially parallel ribs, the inner of said ribs extending across the forward end of ROBERT ALEXANDER COAGHMAN.
