WHlFFLETREE-HOOK.

SPECIFICATEON forming part of Letters Patent No. 576,884., dated February 9, 1897. Application filed August 18, 1896. Serial No. 603,145. o modem To (LZZ whom, it may concern:

Be it known that I, JosnPH E. PATTERSON, a citizen of the United States, residing at Marshfield, in the county of Wood and State of \Visconsin, have invented a new and useful Whiiiietree-Hook, of which the following .is a specification.

The invention relates to improvements in whiftletree-hooks.

The object of the present invention is to improve the construction of whiffletree-hooks and to provide a simple, inexpensive, strong, and durable device for attaching traces to whiffletrees, adapted to enable the traces to be readily connected to and detached from the whiftletree and capable of absolutely preventing them from becoming accidentally unfastened.

A further object of the invention is to provide a whiffietree-hook which will present no projections or points into which the drivingreins can become caught.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a whiffletree-hook constructed in accordance with this invention. Fig. 2 is a plan view showing the same connected with a whif- Fig. 3 is a detail perspective View of the whiifietree-hook, the separable hooks thereof being swung apart.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a Whifiietree-eye formed integralwith a band or ferrule 2, which is secured on the end of a singletree 3 in the usual manner. The singletree-ring is detachably connected with a trace-eye at by a whiflietree-hook '7, which is provided at one end with a continuous eye 8 to receive the whifiietree-ring and at its other end with a split eye to receive the eye 4; of a trace.

The eye 4 of the trace may he of any desired construction and may consist of a link or a chain or the like, as will be readily un derstood.

faces, and when they fit together the outer face of each is substantially flush with the adjacent face of the shank of the other. The shanks of the hooks 10 and 11 are arranged substantially parallel, and the shank of the hook 10 has the eye 8 formed integral with it.

The continuous eye 8, which is disposed in the same plane as the hooks 10 and 11, is provided with an extension or arm- 12, arranged parallel with the adjacent portion of the shank of the hook 10. The arm 12 and the adjacent portion of the shank of the hook 10 are squared or flatten ed, and the adjacent end of the shank of the other hook is pivoted in the space between the arm 12 and the shank of the hook 10 by a transverse pin 13. The arm 12, by being spaced from the shank of the hooked end, provides an entrance-opening to the continuous eye 8, and when the shank of the hook 11 is pivoted in the space the entrance to the continuous eye 8 is closed to confine a whiffletree-e ye therein. The inner end of the shank of the hook 11 is flattened to conform to the configuration of the adjacent faces of the shank of the hook 10 and the arm 12. The short hook 11 is adapted to swing on the transverse pin or pivot 13 to separate the hooks to enable the trace-eye to be readily connected to or detached from the singletree.

It will be seen that the whiffletree-hook is exceedingly simple and inexpensive in construction, that it will enable a trace or tug to be readily connected with and disconnected from a whiffletree, and that it presents no projections or points into which the drivingreins can become caught.

It will also be apparent that the whiffietree hook is adapted for all kinds of draft mechanism, and that traces and tugs cannot become detached by slackening them or turning short or the like.

hat I claim is A whiffletree-hook comprising a shank having one end bent to form a hook 10 and having its other end bent to form a continuous eye 8 arranged in the same plane as the hook 10, the end of the shank which forms the eye 8 being extended along and spaced from the body portion of the shank to provide an entrance-opening to the continuous eye, and the hook 11 arranged contiguous to the hook 10 itnesses:
