WHlFFLETREE-HOQK.

SPECIFICATION forming part of Letters Patent No. 350,492, dated October 12. 1886.

. Application filed July 6, 1886. Serial No. 207,258. (No model.)

To all whom, it may concern:

Be it known that I, Josnrn B. JoHNsoN, a citizen of the United States, residing at the village of Rockford, in'the county of Kent and State of Michigan, have invented a new and useful Whiffletree-Hook, of which the following is a specification.

The invention relates to a hook for attaching the whiffietree to the tugs of a harness, also for attaching the whiffietree to the evener; and the objects of my invention are, first, to attach the hook to a ferrule that may be quickly detached from the whiffletree; and, second, to provide the ferrule with a look, so that when the hook and tug are attached it may be locked by a spring-catch, thereby preventing the tugs from accidentally becoming unhooked. These objects I accomplish by means of the mechanism illustrated inthe accompanying drawings, in which- Figure 1 is a perspective view of the several parts of the whiffletreehooks separated; Fig.

2, a sectional view of the end of the Whittletree applied, on the line XX of Fig. 3. Fig. 3 is a plan view of the hook and a part of the whiffletree. Fig. 4 is a plan view of a certain portion of a whiffletree with a hook applied,

this hook being designed to attach the wh'iffletree to the evener. Fig. 5 is a sectional view on line Y Y of Fig. 4; and Fig. 6 is a side elevation of the center hook and ferrules.

Similar letters refer to similar parts through- I out the several views.

In the drawings, Ashows the ferrule proper, its position on the whiffletree being shown in Fig. 2. Upon this ferrule A is the ferrule J,which fits upon Awith a working fit, so that it may be turned readily, and when unlocked it may be readily detached. 7

To ferrule J is attached the whiffletree-hook K. Within the ferrule J is the grooved cylinder F, which fits into said ferrule with a working fit.

E is an ear of ferrule A, by means of which the ferruleis attached to the whiffletree P with greater strength than it could be by merely fitting it over the end of the whiflietree.

O is a key, which is constructed in the form shown, and which, when in use,passes through the ferrules J and A andinto the cylinder F, the opening in J being shown by M in Fig. l. The shoulder of O at the upper end rests on to ferrule A, and the ferrule J, with hook K,

key 0, and cylinder F, may be turned until the key reaches the end of slot D farthest from the slot 0. At this point the spring S raises.

the button 0", which button is provided with the shoulder m, so that m engages with the notch 15 in the inner surface of ferrule J, thereby locking it.

B is a lug on ferrule A, and when the looking is done,,as above described, the hook K and lug R are in the position shown in Fig. 3.

The operation of this part of my invention is as follows: The cockeye of the tug is placed on the hook K, when the ferrule J is turned until the same is locked. To unhitch the same, press down on button r, and turn the ferrule J until the hook K passes away from lug R.

The book K and lug B may be so constructed that the end of hook K will be attached to the lug, thereby strengthening the hook.

By turning ferrule J to the point where it. was when the key 0 was inserted, the key may be withdrawn, and ferrule J and cylinder F removed.

When I use my device for attaching the whiffletree to'the evener, I use the for ms shown in Figs. 4, 5, and 6, in which T is the hookferrule, and 1 the hook, and 2 the lug. The ferrule T isheld in place by the ferrules V and U.

3 is a dovetail on hook I, and 5 a dovetail groove on lug 2. When the hook is locked, the dovetail 3 engages with the groove 5. ,i is a button having a shoulder which engages with a notch in ferrule T, in all respects similar to the locking device above described,and illustrated by button 1', shoulder at, spring S, and notch tin Fig. 1.

In the attachment shown in Figs. 4, 5, and 6 I do not use the cylinder F, it being unnecessary when my invention is applied to the center of the whiffletree.

Having thus .described my invention, what 3. The combination of whiffletree I, ferrule V, ferrule T, provided with hook 1, and ferrule U, provided with lug 2, all constructed substantially as described.
