PATENT LOGGING DOG OR HOOK.

SPECIFICATION forming part of Letters Patent No. 727,529, dated May 5, 1903.

Application filed November 11, 1902. Serial No. 130,828. (No model.)

To all whom it may concern.-

Be it known that I, CARL J OHON YOUNG, a citizen of theUnited States,residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Logging Dogs or Hooks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an improved logging dog or hook, and has for its primary object the provision of a hook which will be strong in character and may be readily driven into or withdrawn from a log without damaging or displacing the material of the log but to a very slight extent.

Novel details in the construction of the device will be apparent from the detailed description hereinafter when read in connection with the accompanying drawings, forming part hereof, and wherein an embodiment of the invention is illustrated.

In the drawings, Figure 1 is a perspective view of the hook; Fig. 2, a side elevation thereof; Fig. 3, a cross-sectional View on the line 0c 00 of Fig. 2, and Fig. 4 is an edge view of the beak and fin projecting therefrom.

Referring more specifically to the drawings, wherein like reference-letters refer to corresponding parts in the several views, A designates the shank of the hook, provided at its end with an eye 13, designed for attachment to a chain or other suitable draft-lino in the ordinary manner.

0 is the beak of the hook, which projects outwardly at an angle to the shank thereof and is provided with a relatively broad flat inner surface 0, which is straight, as shown in Fig. 2, to facilitate the driving of the beak into the log. The extreme point of the beak o is formed with a sharp cutting edge, and extending from this edge to the base of the beak is a fin D, extending outwardly from the outer surface 0 of the beak. This fin is formed with a sharp edge d, and in contour is an arc of'a relatively large circle merging into a correspondingly-curved portion of the shank A. To strengthen the fin and to facilitate its penetration into the log, the sides thereof are concaved, as at cl, after the fashion of a razor-blade, and these sides taper gradually from the base of the beak, where the fin is of the same thickness as the beak,

to the point of the beak, where the fin is very sharp. By thus forming the sides of the fin it will be seen that the hook may be readily driven into a log without materially damaging the same by displacing the material thereof, as is the case in the employment of a hook provided with a thick heavy beak. The broad fiat surface 0 of the beak will prevent the same from cutting and thereby working out of a log when the log is being drawn from place to place, while the large curved formation of the outer edge of the hook will facilitate the easy withdrawal of the same from the log by a blow upon the back of the free end of the shank A, this latter being important, as it overcomes the disadvantages of a hook the corresponding edge of which is formed upon the arc of a relatively small circle, necessitating a sharp angle between the beak and the shank.

It is to be understood that while a particular construction has been disclosed herein it is not the intention to be limited to the exact details thereof, except in so far as any such limitations may be contained in the appended claims.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. A hook of the character described comprising a shank, a beak connected thereto, said beak having a relatively broad inner surface, and a fin projecting outwardly from the outer surface of the beak and having hollow sides, the edge of the fin and base of the shank being formed upon an arc of a relatively large circle; substantially as described.

2. A hook of the character described comprisingashank and abeak connected thereto, said beak having a relatively broad inner surface and a relatively sharp fin projecting outwardly from the outer surface of the beak having hollow sides, said fin gradually increasing in thickness from the point of the beak to its juncture with the shank; substantially as described.

In testimony whereof I afixmy signature in presence of two witnesses.

CARL J OHON YOUNG.
