LOGGING-HOOK.

Application filed January 30, 1917.

To all whom it may concern:

Be it known that I, OSCAR F. CARLSON, a citizen of the United States, residing at Biglake, in the county of Skagit and State of Washington, have invented new and useful Improvements in Logging-Hooks, of

- which the following is a specification.

This invention relates to hooks which are used in the logging industry, and which are generally known as chocker hooks, the chocker being the length of cable that is fastened around a log while it is being dragged or transported over the ground by means provided for the purpose.

When, in thus being transported, a log starts down an incline and the tension of the chocker is slackened, the cable is very apt to become disconnected from the hook, thereby releasing the log. To provide against this contingency is the prime object of the present invention.

A further object of the invention is to produce a chocker hook of simple and improved construction the same having a link with which the cable or chock is connected. said link cooperating with the bill point of the hook to constitute a locking device whereby disengagement of the book from the cable will be prevented.

Afurther object of the invention is to produce a chocker hook of simple and improved construction having means whereby it will be retained in such relation to the log as to avoid swinging to a position which will permit the disengagement of the cable from said hook.

With these and other ends in view which will readily appear as the nature of the in vention is better understood, the same consists in the improved construction and novel arrangement. and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited,

ut that changes, alterations and modifications within the scope of the claims may be resorted to When desired.

In the drawing,

positions in which the cable may be engaged with the bill point of the hook.

Fig. 3 is a plan view showing another position in which the cable may be engaged with the bill point of the hook.

Fig. 4 is a transverse sectional view taken on the line 44 in Fig. 2.

Fig. 5 is a plan view showing the device applied to a. log and showing the position of the parts while the cable is under tension.

Fig. 6 is a plan view showing the device applied to a log and showing the position which the parts have a tendency to assume when the cable is not under tension.

Corresponding parts in the several figures of the drawings are denoted by like characters of reference.

The hook generally designated by A comprises a Hat body portion or shank15 a portion of which is bent to form the bill 16 having a down-turned point 17 which is located approximately in the plane of one side edge of the shank, one side of the bill being beveled in the direction of the point, the bill thus produced being of approximately triangular shape. The shank or body portion 15 is provided near the front end thereof with an aperture 18 with which a link 19, preferably of oval or elliptical shape, is per manently engaged. The hook is provided at the side portions thereof with flanges 20 which extend downwardly with respect to the shank and upwardly with respect to the bill and the point of the latter, said flanges continuing around the curved end portion of the hook. By these flanges the hook is greatly reinforced enabling it to resist heavy strain without danger of being broken or distorted. The portions of the flanges which extend downwardly with respect to the shank serve an additional purpose in that by engaging or biting into the log when the device is applied and the cable or chock is under tension, the hook will thereby be retained in position with some degree of security so that if the cable should become slackened, there will be little danger of the hook being immediately displaced. The chocker or cable 21 is suitably spliced to or connected with the link 19.

In the operation of this device a turn of the cable 21 is laid about the log, a portion of which is seen at L. and the cable is then engaged with the bill point of the hook. This may only be done While the link is in one of the positions illustrated in Figs. 2 and hook becomes 3, the hook and link being so proportioned with respect to the thickness of the cable and so arranged with respect thereto that only in one of these positions the cable may be inserted between the link and the beveled side edge of the hook. Immediately when tension is applied to the cable, the link will be swung to a position where the opening existing between itself and the point of the reduced to such an extent as to prevent the passage of the cable therethrough. This position is indicated in Fig. 5. Should the tension on the cable become reduced, as would be the case if the log, in

' traveling down an incline, should move faster than the cable, the tendency of the link would be to swing still farther in that direction. as illustrated in Fig. 6, thereby still further reducing'the liability of the cable becoming disengaged from the hook.

As will be seen from the foregoing description, taken in connection with the drawing, the improved chocker hook is extremely simple in construction enabling it to be produced at a moderate expense. Snap hooks and other devices involving the use of springs and the like which have heretofore been used have been liable to the objection of their being likely to become obstructed by snow and ice and also to the danger of loss and breakage of the parts. By the simplicity of the present invention these objections are avoided.

Having thus described the invention, what is claimed as new is:

1. A chocker hook comprising a flat base portion or shank and an approximately triangular bill having a downturned hook lying approximately in the plane of one side edge of the shank.

2. A chocker hook comprising a flat base portion or shank and an approximately triangular bill having a downturned hook lying approximately in the plane of one side edge of the shank, and a link for engagement with which the shank is provided with an aperture near the forward edge thereof.

3. A chocker hook comprising a flat base portion or shank, a bill having a downturned point lying approximately in the plane of one side edge of the shank, one side edge of the bill being beveled in the direction of the point, a link connected with the shank near the forward end thereof, and a cable connected with the link, the parts being so proportioned that the cable may be engaged with the book only when the link is in substantially parallel relation to the beveled side edge of the hill.

4. A chocker hook comprising a flat. base portion or shank and a bill having a point located approximately in the plane of one side edge of the shank, said bill having a side edge beveled in the direction of the point, said bill and shank having longitudinal continuous flanges at the side edges thereof, said flanges projecting downwardly with respect to the shank.

5. A chocker hook comprising a flat base portion or shank and a bill having a point located approximately in the plane of one side edge of the shank, said bill having av side edge beveled in the direction of the point, said bill and shank having longitudinal continuous flanges at the side edges thereof, said flanges projecting downwardly with respect to the shank. in combination with a link connected with the shank near the forward end thereof and a cable attached to the link.
