'Be-it known that I HAR LD SAI EYIK,-a subject of the King :of Norway, resld ng at Hommelvik, near'lrondhjem, NOTWaYfh JYGRJ 5 nvented'certam new and useful Improve- 'ments in Lumber-Rafting. Apparatus; and

I do hereby declare the following-to be a full, clear, andexact description vof the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, referencebeing had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My'invention relates to apparatus for assembling lumber into rafts (rafting apparatus) whichare used for making rafts for Y the floatingortowing of thelumber to be transported.

My apparatus differs from other apparatus of similar kind essentially therein that it is wholly mounted on board of a pontoon, boat or. other floating craft, so as to. be easily movable and that it lifts the lumber or trunks one by one out of the water, carries them across the pontoon and drops them into a channel specially prepared for the rafting operation.

' A preferred form of my apparatus is 30 shown in the accompanying drawings in which: I I r 1 Figure 1 is a side View, with parts in section, of my improved apparatus.

Fig. 2 is an end view, with parts in sec tion.

Fig. 3 is a detail plan view of the guide As will be seen from the drawings the whole ofthe machinery is mounted in a pontoon l or other floating craft the motor 2 with its driving. gear beingplaced on the bottom and wholly built in thereby making it possible to have the apparatus towed even in rough weather.

This? channel is-formed between the inner side of the pontoon 1 and another pontoon 7, araft or the like. Flexible binding members 8 arepartially submerged in the'channel and are 4' connected at their ends to the two pontoons g V as shown in Fig. 1. When a sufficientnum ber of logs have been deposited in the, channel, the ends of the ropes8 are fastened together' and-the ropes tightened to formia, V circular or oval bundle adapted to be towed from between the pontoons.

vAs will. be seen from the drawings the Y guide arms 6, which may berailway rails Y or the like, are adjustable vertically as well 7 as horizontally. The vertical adjustment"is 1 I effected by turning thearms about a shaft 9. f.

The arms are keptin position by aid of bolts 10 and corresponding nuts 11, said boltsj being put through holes bored in the. lower ends 12 ofthe guide arms 6 and through the i interstices between the-parallel ribs 13; c} In the drawings there are arranged five su guidearms 6 infived-iiferent positions (at V five different angles), whereby the placing} of the trunks in the rafts maybe governed.

to regulate the distance between .them-for handling logs of different lengths, is effected by loosening the nuts 11, and gl collars;

14, the latter being adjustably mounted on the shaft 9 on each sideof the arms, and then sliding saidarms along'the shaft until they are spaced apart the desired distance. The complete apparatus being mounted on a pontoon or other floating craft, it may be used anywhere in-rivers, seas and fjords, j

as it may easily-be towed from one place to another. a
