TOOL FOR- H AULING TIMBER AND THE LIKE.

To all whom it may concern:

Be it known that I, MOGENS FRAAS Boson, citizen of Norway, residing at Jacob Aalls Gate 414:, Christiania, Norway, have invented new and useful Improvements in Tools for Hauling Timber and the Like, of which the following is a specification.

After trees have been cut down in the forests they are gathered into large piles. The timber is skidded, and for hauling the logs to the skidding place different tools are used in different localities. In the Scandinavian countries a steel wedge driven into one end face of the log and connected by a chain to the swingle-tree is most used. These wedges, in order to sit fast with the necessary security, are comparatively large, say from 3 to 4 inches long and 1 to 1;}; inches wide. On account of the large hole left by the wedges and the many serious consequences thereof, the said wedges are exceedingly objectionable. Moreover, they are not secure in operation. Also chains slung around the log end are used; but they waste a great deal of time, and are especially difficult for one man to handle. Tongs, such as those commonly in use in the United States of America and Canada for hauling very large logs answer the purpose when the log is being hauled on level ground or up hill; but when the log slides down a slant or meets an obstacle, the chain becomes slacked, the log runs ahead against the swingle-trees and the tongs drop off. A log hauling tool which is handy, quick and secure in use has therefore been lacking.

My present invention has for its object to provide a hauling tool, whichas is proved by experience-has not the disadvantages hereinbefore mentioned. This tool can be quickly clamped upon and released from logs of any dimensions without injuring the logs. The tool is held fast even under the most unfavorable conditions, and even when the pull on the log is in any direction whatever relative to the log.

My invention is illustrated in the accompanying drawings, in which,

Figure 1 is a side view partly in longitudinal section, of such a tool clamped upon a log of small size. Fig. 2 is an end view of the tool, looking from the left in Fig. 1, one of the turnable hooks being removed. Fig. 3 is a plan view corresponding to Fig. 1. Figs. 4 and 5 are side elevation and end view respectively of the tool in a modified Specification of Letters Patent.

taking up forwardly directed hauling forces,

partly with means, which by engagement against or by projecting into the log material holds the mounting fast against longitudinal displacement on the log in backward direction, and partly means as a hook or equivalent means adapted to be driven into the end face of the log in order to hold the mounting fast in lateral direction relative to the log and to take up upwardly directed hauling forces. 'The traction means is directly or indirectly connected to the mounting in such a manner, that there is no tendency toward loosening the different hooks or teeth when the hauling forces alternate in direction.

In the construction shown in Fig. 1 the tool consists of a stiff angular mounting having at each end a double hook. This mounting comprises a long part or arm 1 placed in engagement with the longitudinal side of the log 2, and a short part or arm 3 the end of which is formed like a finger 4: adapted to engage the end face of the log. At the end of the long arm 1 a pivoted double hook 6 (hereinafter termed longitudinal hook) is attached by means of a bolt 5 riveted or screw threaded or secured in position by washer and splint. This hook is provided with two curved teeth 7 connected together at the upper part by a bridge piece 8 (see the sectioned surface in Fig. 1). This bridge piece is struck when the hook is being driven into the log, and its under side engages a nose-shaped extension 9 of the part 1. A similar hook is the end hook 10, which by the bolt 11 is pivoted to the short part 3 of the mounting and the curved teeth 12 of which are driven into the end of the log by striking against the bridge piece 13, the inner face of which piece 13 engages the back side of the finger 4. At the underside of the long part 1 is arranged a fixed downwardly directed tooth 11 also adapted to be driven into the longitudinal side of the log. The drafting or traction means consists of a ring 15 passing through a hole 16 in the angular mounting near its corner and linked to another ring 17 to be connected to the hauling chain of the swingle-tree.

When the hauling force has the direction indicated by the arrow 18 (Fig 1), this force is transferred through the long part to the longitudinal hook 6 and through its teeth 7 to the log, while the end hook 10 is not acted upon. The same is true, when the hauling force is inclined forwardly and downwardly (arrow 19), in which case any tendency of the part 1 to turn about the bolt 5 relatively the hook 6 is counter-acted by the nose 9. A hauling force inclined forwardly and upwardly (arrow 20) is taken up by both hooks through the angular mounting, a rotation of the end hook relatively the finger 4 being prevented by the bridge piece 13 engaging the back of said finger. If the hauling force however, be directed against the log (to the left in Fig. 1) it is transferred through the finger 4 directly to the log on account of the rigidity of the angular mounting. Finally, if the force be directed laterally (perpendicular to the plane of the drawing), it is taken up by the fixed tooth 14 in connection with the two hooks.

It will be seen, that the holes left in the log from the hooks in the log are very small and they cause no inconveniences of the sort mentioned above. Moreover it has been experienced that the tooth 14 serving to take up lateral forces may be wholly dispensed with, because such forces are securely taken up on account of the fact that in the end of the log, two teeth 12 are present side by side.

A construction having no fixed tooth 14 is shown in Fig. 4 in which also the portion 21 corresponding to the finger 4 is provided with two fixed teeth 22 instead of having a pivoted double hook 10 as shown in Fig. 1.

Further the longitudinal hook 23 has a single tooth and is attached in a forked end portion of the part 1. The hook 23 has two side projections 24 which, when the hook is driven in, engage two noses 25 forming rear extensions of the forked portion. The

parts

24 and 25 thus here serve the same purpose as the parts 8 and 9 in Fig. 1.

Another modification is shown in Fig. 6, in which the longitudinal hook 26 is made integral with the long mounting part 1 and in which the drafting member 15 forms at the same time the pivot for two independently turnable end hooks 27. Further the engaging finger here is replaced by a wedge 28ito be driven in between the end face of the log 2 and a bearing provided on an over-hanging portion of the part 1. Instead of the loose wedge 28 I also may use a hook 29 turnable on the part 1 as indicated by dotted lines in Fig. 6. The wedge 28 or the hook 29 thus takes up the hauling force when the same is directed against the log. In the construction shown in Fig. 7 all pivoted hooks are replaced by nail-

like teeth

30, 31 and 32 driven inclined into the log and of which the tooth 31 takes up lateral forces.

The preferred construction shown in Figs. 8 and 9 is difierent from that shown in Fig. 4 partly in that the face 33, upon which blows are struck for driving in the teeth 22, is arranged above the drafting member 15 in order that the latter may not be in the way during the driving-in, and partly in that the edges 34 of the pivoted hook 23 is disposed longitudinally instead of transversely to the log. The advantage of this disposition of the hook is that the wood fibers during the driving-in of the said hook are not cut but merely pushed aside; and that the hook remains more securely stuck in the wood. In this form the nose (25 of Fig. 4) is omitted.

Having now described my invention what I claim as new and desire to secure by Letters Patent is:
