ABTHUR J. ZIPP, OF CENTRAL LAKE, MICHIGAN.

LOGGING GRAPPLE 0R TONGS.

Application filed October 30, 1917.

To all whom it may concern:

Be it known that I, ARTHUR J. ZLPP, a citizen of the United States, residing at Central Lake, in the county of Antrini and State of Michigan, have invented certain new and useful Improvements in Logging Grapples or Tongs of which the following is a specification.

This invention relates to logging grapple or tongs.

The objects of this invention are:

First, to provide an efl'ective loggin grap le means for recovering submerged logs our the bottoms of lakes and rivers.

Second, to provide means of the character described comprising a pair of lo ging tongs with a sliding support for ho ding the tongs in position to en ge with the logs at the bottom-of the la e or river as the tongs are drawn along.

Further objects, relating to structural details, will definitely appear from the de tailed description to follow.

I'accomplish the objects of my invention by the devices and means described in the followin specification. The invention is clearly efined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawin forming a part of this specification, in w ich:

Figure I is a side elevation of my 1111- proved doggin tongs.

Fig. II is li ewise a side elevation of my improved tongs showing the cable connections thereto and the tongs in open position.

Fig. III is a plan view.

Fig. IV is an enlarged sectional detail taken on a line corresponding to line 4-4 of Fig. I.

Fig. V is an enlarged detail of the lower end of the rear tong.

Fig. V1 is an enlarged detail taken on a line corresponding to line 66 of Fig. V.

Fig. VII is an enlarged detail of a modification of the lower end of the rear tong corresponding to the view of Fig. V.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

The bottoms of many lakes and rivers which have formed Water courses for log Specification of Letters Patent.

ging operations are covered with. or have thousands of logs embedded therein. The greater proportions of these logs are hard wood, which, on account of their high specific gravity, become watcr'logged in a comparatively short time to such an extent that they sink to the bottom of the water courses over which they are being transported. The water acts as a preservative and the re covery of these log is today of considerable con'm'iercial importance. The object of this invention is, therefore. to provide means for easily recovering these sunken logs which either .lie upon the bottoms of the lakes and streams. or may be partially embedded therein.

Referring to the drawing, 1 and 2 indicate a pair of logging tongs pivotally mounted upon the bolt 3. Rings 4 are pivotally secured to the upper end of each of the tongs 1 and 2 and a cable receiving ring 5 passes through the rings 4. The structure thus described is ordinarily known as a logging, or skidding tongs.

I provide a sliding support for the tongs, the support in the structure illustrated comprising a pair of runners 6 to the forward ends of which at i" are pivoted arnis T. These arms extend upwardly and inwardly. as shown in Fig. III, lo receive the pivot bolt 3 of the tongs. The upper ends of these arms 7 are provided with holes in which the collars S on the bolt 3 are disposed,see Fig. IV. Plates 9 are bolted to the runners 6. there being a wooden filler 10 between the runners (3 and the plates 9. A spreader link 11 has its outer ends pivotally connected with the said runners. These runners and the fillers 10 may be made entirely of metal plates of integral construction, a simple modification not necessary to illustrate.

A pointed log engaging finger 12 slides in guides 13 on the prong of the rear tong and is urged forwardly )y the spring 14. Normally the end of this log engaging finger projects beyond the end of the prong of the rear tong.

In Fig. VII, I show a modification of this pointed engaging finger 19 pivoted at 20 and held yieldingly in place by spring 21. a cord loop 22 being provided to keep the parts in cooperative relation.

A ring 15 pivotally secured to the lower end of the tong 1 receives the end of the (Zillilti it; which is used for dragging the tongs along: the bottom of the lake or river, the upper end of the cable 16 being connected with a tug. or other similar structure. A ring 17 secured to the lower end of the ton 2 forms a connection with the cable 18 which can be used for retracting the tongs to disengage the same or whenever desired.

In use the tongs a re lowered to the bottom of the lake or river by the cable 19 and are then drawn over the bottom by means of the cable 1.6. If the prong of the rear tong should engage the log L in the upper position, indicated in dotted outline in Fig. II, the cable 16 is slacked off and when a pill. is exerted on the cable 19 the tong 1 engages with the log on the op Josite side. The log is then raised by the ca le 19. If. however, the log is artially embedded in the bottom of the lalre or river 0'1, for some other reason. it occupies the position relative to the p'r'on'g of the rear tong shown in dotted outline at L this tong would Very likely slide over the log if it were not for the provision of the log engaging finger 12. This finger is sharpened to a point and when it engages a log, it arrests the movement of the tong whereupon the tong 1 is immediately lowered by slacking on the cable 161 and pulling on the cable 19 to engage the log. This operation causes the prong of'the' tong 2 to engage with the Side of the log and the log can then be raised.

\Vhile I have described the preferred embodimcnt of my invention in detail it is capable of other adaptations and modificatio'ns within the scope of the following claims.
