T all 'whom it may Concern.'

Be it known that l, Oscar: (leaner, a subject ot' the `King ol. Great Britain, and a resident of Queen Charlotte islands, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Log Rafts, of whichr the following is a specification.

My invention relates to improvements in log rafts, and the object ol' iny invention is tc devise a means of transporting logs from place to place in raft-forni in which the logs are strongly and securely bound together whereby the raft so formed is, not liable to be broken up in rough weather, the arrangement beingsuch that the logs forming the raft may be spilled easily from either side of the rait centre on reaching the unloading ground so that a great saving'in both time and labour is rendered possible and at the saine time minimizing the risk of a log ain when spilling. A tun ther object is to so arrange the bottomtop cables, that is, the lines passing over the upper body of the raft, in such inanner that they are readily accessible so that they can be unloosed and taken oil at any time and, if required7 before spilling the raft.

I attain these objects by the construction illustrated in the accompanying drawings in which- Fig. l is a cross sectional view of the raft iloor, taken in front of a cable.

In constructing a raft according to my invention a inain central log'l is laid down, from which .log the whole Yfabric depends. In long rafts of course this centre log is formed out of a'nurnber of logs placed end to end and chained together in the well known manner. O11 each side of the centre log l are placed side by side the logs which forni the raft Hoor, these being indicated by the numeral 2and being in number as inany as are required te make up the width and lengthcf the raft, and along each side or the outerniost locr logs 2 are placed the side sticks s and 5, these side sticks being as inany in number laid end to end and chained together in the usual nianner as are required to extend the entire length of the rait. These legs aboveunentioned constitute the vdoor et the raft and they arebound together by spaced pairs of cables arranged throughout the length or the floor and `indicated by the numerals 6 7 on one side of the centre log l and 8 9 on the opposite side. The cables are wrapped around the tloor logs in the inanner shown in Fig. 5 with reference to cables 6 and 7 and diagra'nnn'atically in Figs, 2 and 3,'that is to say, the cable 6 is secured to the centre log l at one end in any suitable inanner such as by taking a turn round-the centre log and vthen clamping the` end thereto, as' indicated at l0, afterwhich it is then passed over the top of the tloor log-2 next the centre log and under and around it, then carried over the top of it and on to the next floor log, passing overV the top of it and then under and around it and so on until it has been wrapped around all the licor logs on that side of the centre log, being finally passed around the side stick l one turn and having its free end clainped te it, as at 1l. The cable' 8 on the opposite side of the centre logis wrapped around thek logs on that side in the same manner and secured to the side stickv 5 by the clamp 12. u

The cable VZ of the pair 6-7 yis spaced a short distance from the cable, say about 4 feet apart,fand itis also secured at one end to the centre log l by the clamp 13 and then 4wound around the floor logs on the saine side as the cable 6 in a siinilar manner to the vwinding ci that cable, only the cable 7 is passed all the time .first under the bottoni of the logs and then around thein, being inally clamped atitsA free end, as at lll, to the side stick-Li@ The cable 9 of the pair 8-9 on the opposite side of the centre log is wrapped around the logs in the saine manner as has just been described with reference to cable 7 f and its :tree end is also clamped to side stick 5.

lt will thus be seen that the floor of the rait consists of a main central log extending of the raft on each side of a loor ot longitudinally eX- tending logs, each such floor being bounded on the outside by longitudinal side sticks connected end to end and that the logs ot the door so constructed on each side ot the centre log are lirmly bound together by cables arranged at designated points throughout the length of the raft in spaced pairs, the cables of each pair being secured at one end to the centre log and being then wrapped around the logs oin the respective Hoor, one cable passing all the time lirst over the top ot the logs and the other cable passing all the time first under the bottom ot the logs, or in other words, the cables of a pair, starting from the centre log, are wound around their respective logs oppositely to each other, as indicated in Figs. 2, 3 and 5, their free ends being inally secured to the side sticks so that the logs are prevented from rolling and the whole door is irmly bound together.

longitudinally which is laid Thus is formed the lioor ot the rattonwhich the main body ot loose logs, indicated by the numeral 16, is loaded, and these logs 16 are securely held together on the loor by means ot the bottom- top cables 17 and 18, which cables are arranged as shown in Fig. e, that is, the cable 17 is passed at one end around the side stick e and clamped to it, its tree end being then passed downwardly between the side stick and the adjacent door log, and then carried along transversely under the floor of the raft and passed upward ly between the side stick 5 andY the adjacent Vfloor log 2 so that its tree end hangs over the v side stick 5 when the raft is being loaded.

Y stick l when loading. After the The cable 18 is arranged in a similar manner, being clamped at one end around thc side stick 5, its free end passing downwardly between the side stick and the adjacent floor logand being then carried transversely under the raft floor and passed upwardly between the side stick 4l and the adjacent floor log, hanging at its tree end over the side raft is constructed and loaded to trie full capacity the tree ends ofv the bottom-top cables 1'? and 18 are then gathered up and brought together and clamped tightly on top of the main body of the logs 16, as shown in Fig, 6.

The ends of the rait are formed in any approved manner and need not be described.

The utility and advantages of suoli a raft will be readily apparent, as it will be seen that the logs may be spilled readily 'from both sides et the centre so that a log jam when discharging is not liable to occur and as the floor is in eiiect formed ot two independent side tloors the cables connecting the logs of each floor are reduced to a minimum length so that they are handled and manipulated with comparative ease, while a further advantage lies in the arrangement of the bottom-top cables which, it will be seen,

are readily accessible and may be taken o at any time and, if required, without the necessity ot' spilling the raft.

lt will be evident, therefore, that l have devised a log raift which is capable ot being constructed and operated with great facility, thus providing a uset'ul and convenient means for transporting large bodies oi5 logs from place to place.
