HOOK.

To all whom it may concern;

Be it known that I, CLAYTON T, EAID, a citizen of the United States of America, residing at Portland, in the county of Multnomah, in the State of Oregon, have invented certain new and useful Improvements in Hooks, of which the following is a specification, reference being had t the acompanying drawing.

My invention relates to hooks adapted to be applied to many and various uses, and to be manufactured of many different materials and in many sizes, varying all the way from jewelers hooks of small delicate construction intended for personal wear, to the heavy logging hook illustrated, for example, in the drawing,

My hook comprises, in all its various forms of embodiment contemplated, a hookproper, a keeper therefor, and a preferably automatic keeper-lock. Those principal elements in combination, and by preference also certain additional features, go to make up a device which is distinctively strong, and du-- rable, and which may be relied upon in service always to perform its oflice.

What constitutes my invention will be hereinafter specified in detail and succinctly set forth in theappended claims.

In the accompanying drawing, wherein my invention is shown as embodied in a form known in the loggingart as a choker hook,

Figure I is a side elevation of my hook looking toward the closed keeper, and illustrating parts of a cable to which it performs the office of a choker hook.

Fig. II is a central vertical section of the hook proper shown in Fig. I, the view being taken at right angles to that shown in Fig. I, and the keeper being shown in elevation.

Fig. III shows the device illustrated in the preceding figures, with the keeper open, and showing those relative positions of the hookproper and lock which only admit release of the keeper.

Fig. IV is a side elevation of my hook taken at right angles to the View shown in Fig. I, and corresponding in all respects to the device shown in the other figures, with the single exception that a cable socket is, by way of modification, shown in Fig. IV in place of the eyelet shown in the other figures.

Referring to the numerals on the drawing, 1 indicates a member that is representative Specification of Iietters Patent.

of any suitable element for coupling my hook to another member in service. It is shown as provided with an eyelet or transverse perforation adapted, as shown in Fig. I, to receive the bend 17 of a cable 16.

In Fig. IV a cable socket 18 in place of the eyelet is shown.

The member 1 which is in effect a clevis includes a lock which preferably consists of a breast plate 2 preferably extending between and preferably integral with check plates 3. The check plates as shown are provided for the accommodation of a pivot pin 4; which is preferably in substantial coaXial disposition to the breast plate 2. Upon the pin 4 is pivotally mounted the legs 7 of a preferably bifurcated hook-proper 5, so that the member 1 may be oscillated relatively to the hook 5 to bring those members from their normal operative positions shown in Fig. II, for example, to that shown in Fig. III, wherein they are disposed substantially at right angles one to the other. The hook 5 is preferably of solid construction with the exception, in addition to that already noted, that it is preferably provided near its free end with a bifurcating recess 15 whose legs accommodate a pin 10 upon which is pivotally mounted a keeper 11. The keeper is preferably made ,of a shape somewhat resembling a letter 8. Its function is to close the opening of the hook 5 in such manner as to secure the hook 5 to its work or to any member to which it may be applied or hooked. To that end the curvature .of the keeper is preferably modified from the true 8 shape by an indented curved face 13 which, when the keeper is closed, as shown in Fig. II, completes, transversely With the inside contour 6 of the hook 5, a

' true .circle.

shape and dimensionsto hook over the median portion of the pin 4 in the space between the legs 7 of the hook 5. In that position it is secured by the lock, specifically the breast plate 2. Freedom of pivotal movement of the hook 5 upon the pin at Within the limits imposed by the extent of the breastplate 2 is permitted without disengaging the keeper 11 from the look. It is only when the member 1 is swung to such a position relatively to the hook as is shown in Fig. III, that it is possible to introduce the free or hooked end of the keeper into engagement with the pin 4 or to disengage it therefrom after engagement. It should also be observed in this connection that positive actuation of the keeper is necessary to disengage it from the pin even after the members 1 and 5 are in position to admit of such disengagement. The angle of adjustment between-the parts 1 and 5 which permits the described actuation of the keeper may be somewhat varied in the construction of the device, but is, for reasons hereinafter set forth, preferably at least a little greater than a right angle.

Particular reference is now made to Fig. I for the purpose of explaining the specific application of the invention to logging purposes. In that figure the cable 16 is shown as secured at one end 17 to the member 1 of my device, its slack end being inserted through the circular aperture defined between the hook 5 and indentation 13 of the keeper (see Fig. II) and free to slide therein. Freedom of sliding motion is facilitated by the presence of the lugs 12 and by the inside curvelinear contour'of the hook 5 in dicated in dotted lines designated by the numeral 6 in- Fig. I. In operation the bight of the cable 16 between its end 17 and the point at which it enters the hook 5 ispassed around a log or logs and is drawn taut about its load by tension on the free end of the cable. The object of my device, as a choker hook, is to effect freedom of movement of the cable 16 in either direction through the hook with perfect security of engagement In handling logs the loads are exceedingly heavy and provision must be made for drawing the bight of the cable taut about the load in order to hold it, for slacking it without kinking the cable, for insuring the hold of the hook on the cable inservice, and for safely and conveniently releasing the hook I from the cable whenever required. All these advantages are obtainable to a maximum degree by the aid of my invention.

. My device permits the cable to run freely through the hook which is kept securely closed by the keeper 11 as long as there is tension on the cable. The flexibility of the cable, the pivotal action at 4, and that between the hook and the cable at 6, all combine to draw the bight of the cable under tension snugly around the load and to eliminate abrupt bends or sharp projection of any of the members. The keeper is prevented from escape from the lock unless those members assume relatively rectangular positions which the presence of a load in the bight prohibits, so long as tension on the cable is maintained.

My invention is equally applicable to any fiexiblemember, that is, in use, ordinarily under-a tension jhowever slight that is sufficient to keep the members 1 and 5 alined against disengagement of the keeper by the look. It may be applied to watch chains for example, to harness, particularly tugs reins, and back straps, and to a variety 0 similar uses unnecessary to enumerate.

In application to lighter uses the dimensions of the various members although they bear the same relationship one to another as that described above, may be modified to suit the particular use.

' It is not my purpose to limit my invention in any wise to mere structural, details, but to reserve the right to modify and vary the same within the principle of the invention as herein set forth.

Except in choker hooks, in Which they perform a useful function as has been specifled, the extended width of the hook, indicated in Fig. I, and the lugs 12 may be dispensed with, if desired.

What I claim is:

l. A hook comprising, in combination, a hook-proper, a keeper secured in fixed pivotal relationship thereto, and a lock member automatically operative under tension applied endwise of the hook, as specified, to confine the keeper in position to close the open-end of the hook-proper.

2. The combination with a hook, and'a coupling member hinged thereto, of a movable keeper for the hook, and a lock'member carried by the coupling member in operative relationship to the keeper.

3. The combination with a hook, and coupling member hinged thereto, of'a movable keeper for the hook, and a lock member operative to engage and disengage the keeper by the movement of the coupling member on its hinge.

4C. In a hook, the combination with a hook-proper, a keeper hinged to the free end thereof, of a coupling member hinged to the hook-proper constituting a lock for the fine the keeper in position to close the open end of the hook-proper, but when turned upon its pivot beyond such limits to release the keeper.

6. In ahook, the combination, with a hook-proper, another member, and apivot pin uniting the two, of a keeper pivoted to the free end of the hook-proper and having itself a free end adapted to make engagement and disengagement with said pin, and means upon said member to compel said engagement or to permit said disengagement at will.

7. In a hook, the combination, with a hook-proper, another member, and a pivot pin uniting the two, of a keeper pivoted to the free end of the hook-proper and having itself a free end adapted to make engage ment and disengagement with said pin, and means upon said member to compel said engagenient or to permit said disengagementat will said means being normally operative by alining tension between said hook and member to compel said engagement.

8. In a hook, the combination with a hookproper, a keeper pivoted to the free end thereof, and a lock member, of means upon the keeper defining with said hook-proper a circular aperture for effecting free sliding engagement with a cable or the like.

9. In a hook, the combination with a hookproper, a keeper pivoted to the free end thereof, and a lock member, of means upon the keeper defining with said hook-proper a circular aperture for effecting free sliding engagement with a cable or the like, and lugs upon opposite sides of said keeper adjacent to said circular aperture.

10. The combination with a hook-proper and a pivot pin, of a movable keeper having a pivotal connection with said pin and making engagement with the free end of the hook-proper, and another member connected with the pivot pin and controlling movement of the keeper.

11. The combination with a hook proper, and a member in fixed pivotal relationship thereto, of a keeper movable with the hook so as to open and close the same, and means permitting the opening of the keeper only upon setting the hook and the members secured thereto at a predetermined angle one to the other.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
