:3: Claims. (015100- 31) The present inventionrelates to" improvements in equipment for the gathering of pulpwood, ties and the like from the woods where such materials arecut, and transporting such-cut Wood to its final destinationgand the principal objects'of the invention are-to provide equipment 'by means of which the wood, "as it is cut, is

gathered into measured units then formed into bundles and securely tied so thatsuch bundles 'may be easily and quickly shifted 'to-an'd from transport equipment.

A further important object is to provide a =mechanical equipment which will 'form a measured load of cut wood into a round compact bundle, permitting lifting ties to be "secured around the bundle while held by the forming apparatus.

A further object is to-provide a bundle-liftingmeans in close association withthe'bundling means so that the bundle "maybe quickly shifted from the forming means to the liftingmeans.

The principal features of the invention "con- "sist in the provision of measuring "receptacles "to'receive, measure andhold the cutwo'odand "in providing a suspension means adapted to be carried by a crane to be placed 'aroundthe measured quantity of wood and operated to form a round, tight bundle.

A further feature consists in the provision of flexible tie members to be *boundaround the ends of the bundle and to provide=means for lifting the bundle by means of a .crane and to retain the bundle in shape'in secure form until ready for final disposal of the wood.

In the"accompanying-drawings Figure '1 is a side elevational "view of a wood measuring and holding equipment containing a measured load -of wood.

Figure 2 is a side elevational'view showing-the apparatus for forming the measured load of'wood into a bundle and supporting same fromacrane.

"Figure8 is a "si'deelevational 'view "of the .tie locking -member shown in its open position.

Figure9 is an "enlarged cross sectional view through the line 9-9 of Figure 7.

Figure 10 is "adiagrammatic plan illustrating the method of woods operation with apparatus as herein described.

Inthe. ordinary operation .of cutting pulpwood and ties, after thetrees are felled they are out .into .uniform lengths. The out wood is then vpiled as near as possible'to tote roads where it is loaded on sleighs'or trucksto be taken out of the woods.

Such procedureentails a great deal of duplicate handling of'loose woodand it is the particular purpose of this invention to provide equipment which will obviate thehandling of 'loose woodJfrom-the period immediately afterit is out until it is delivered to its destination.

This objective is accomplished by providing equipment .as hereinafter described.

iSmallland scows, such as illustrated in'Figures 1 and 2, are formed of a pair .of spacedapartlongitudinal skids [,which are rigidly connected. by cross .bracesrand adj acentlto each end of these. skids is arrangeda stake 2. These stakes.

.are spaced -apart longitudinally and of such a height .as .toforma measuringunit, and the Wood as -it.is cut into lengths .is .placed crossways .of .theskids and piled'between the stakes .until level with the .top, which thus forms a .de'finite unit .of measurement.

A suitable. type of mobile crane .may be used .intthe woods paths so that its boom may operate closein-to .where these scows are located. Thetboom-c of the .crane is .preferablyiprovided withdoublehoisting cables '4 and 5.

In the end of the cable 4 is attached a yoke 6, hereshown in Figures 4 and 5, preferably fabricated of'sheetmetal and, having'apair of eyes 'l'welded'or otherwise secured *at'thebottomedge and spaced inwardly fromthe ends. 6n the "ends "of the-yokeS arearranged sockets 5, in which-are' tied or securedby wedges in a well known manner, the=ends of a palr of calbles 9. These cables are threaded through clevis loops l0 around the grooved sheaves H which are mounted on a spreader shaft l2 which holds the sheaves the required distance apart.

The ends of these cables 9 are provided with hooks I2 to hook into the clevis members I0, thus forming a cable loop at each end of the yoke member 6. The cable loops thus formed may be placed around the end of the cut wood lengths packed in the land scow and when the cable 4 is raised by manipulating same through the crane mechanism the flexible loop rove through the sheaves ll pulls around the ends of the logs or ties and form them into a round cylindrical bundle.

When the cable 4 is thus manipulated to operate the forming loops to form the bundle they are held in suspension for a brief period, during which period flexible tie members are placed around the bundle outside of the looping cables.

These tie members, as illustrated particularly in Figure 3 and in Figures 7, 8 and 9, constitute a length of cable [3 or chain, to one end of which is pivotally attached a link member l4. To thev opposite end of this link member is pivotally secured a lever l by means of the pivot pin 16.

Both of these members are, as illustrated in the enlarged cross section in Figure 9, formed of U-shaped'cross section and they fit one within the other.

Pivotally attached to one end of the member I5 is a bar I! which is preferably T-shaped in cross section and inverted. To the outer end of this T-bar is connected 2. locking hook lever IS.

The lever' I5 is provided with an extension tongue I9 which extends over the end of the lever I8 and is held in locked position by a U-shaped link 29 which when swung on its pivot first releases the lever then the hook lever l8. A cantilever spring l9 carried by the tongue 19 of lever 15 serves to engage under and hold the link 20 in the lever securing position of Figure 7 against accidental displacement.

One end of the cable 13 is provided with chain links 2| which are selectively hooked in under the hook link I8. link mechanism described is slipped around the outer end of the bundle held by the looping cables 9 and by means of the locking lever end, they are drawn taut.

The link I4 is provided with a chain link 2| and these links are engaged by hooks 2'2 mounted on a yoke 23 carried by the cable 5 of the hoisting crane.

When the hooks 22 are inserted into the links 2| the cable 5 is operated to lift the bundle and when the strain is relieved from the looping cables 9 the hooks 12' may be disconnected from the sheave clevises and thrown clear of the bundle. The bundle is then lifted and swung by the crane to be placed with other bundles in a pile close to the crane runway or path in the woods from which it may be lifted to be placed on to a sleigh or truck.

The bundle is retained snugly tied by the tie cables l3 until it is delivered to its final destina' tion. Consequently the wood lengths are held from scattering and are handled in snug, tight bundles.

It will be readily appreciated that the use of an equipment such as herein described will greatly facilitate woods operations in the handling of pulpwood and ties and a great saving in time and labour will be effected both in the woods and on transports such as trucks, trains or boats.

In a movable land scow equipment for wood handling having a hoist and a yoke connected with the hoist and means operated by the hoist for forming a measured quantity of wood lengths into a cylindrical bundle,'tie means adapted to encircle said cylindrical bundle and to engage said hoist, said tie means comprising a pair of flexible cables each having secured at one end thereof a link of U-section, a U-section lever pivoted intermediate its length to the other end of said link, a T-section bar pivoted at one end to one end of said lever with its web being adapted to be received within said lever, a locking lever hook pivoted to the other end of said bar, said lever and locking lever hook being adapted to overlap on being swung inwardly of said bar ends, means on said bar to maintain said levers in overlapped relation, means on the other end of said cable adapted to engage said locking lever hook, and means adapted to connect said cables .to said yoke in spaced relation.

, be received within said lever with said lever swung inwardly of the bar end, said link with said lever swung inwardly of the bar end to receive said bar receiving thercwithin said lever and said bar, a

locking lever hook pivoted to the other end of said bar, said lever and locking lever hook being adapted to overlap on being swung inwardly of said bar ends, means on said bar to maintain said levers in overlapped relation, and means on the other end of said flexible tie means to engage said looking lever hook.

3. A device as claimed in claim 2 in which the means maintaining said levers in overlapped relation comprises a U-link pivoted to said bar and swingable in one direction to clear said locking lever hook and in the other direction to clear said U section lever with said levers overlapped.
