- ll Claims.

My invention relates to the art of coastal and seagoing transportation of logs. v

Logs on the Pacic coast of North America g are usually assembled into booms comprising from six or eight to twenty or twenty-five sections of logs, each containing approximately forty thousand feet per section.y Thelogs are held kbetween chained-together boom sticks overlaid 3 with swifter sticks which are chainedand secured to the chains that fasten the boom sticks together. These booms are towed long distances; on the Pacic coast tows of live hundred to a thousand miles are no uncommon events. Such booms however can only safely be towedduring calm weather. If one of these large booms gets caught out in roughweather it is no ,uncommon thing for the tug `to lose its tow through thelogs jumping out and escaping from thev boom proper. When this happens, great expense and delay areincurred because of the necessity of gathering up the logs and making up the booms again. It is to avoid the objectionable features .of the above methods, now commonly employed,

tion. Further, it is an object to provide a method and meansrby which deep-sea towing operations oi loks may be carried on by the use of specially constructed scows and arranging the logs on the scows so that they will not come loose in rough weather, and so that they may be quickly and easily discharged or unloaded-from the scow by the use of interlaced cables laid between the logs when the logs are being loaded.

A further object is to arrange the interlaced cables in the form of bridles, the ends of the bridles being anchored to the scow. below the floor level thereof, the loop of the bridles being likewise anchored by means of eye-bolts, suitable means being provided for placing th bridles under tension. v

Again, it is an object to provide a means for securing logs upon a scow in groups of logs so i arranged that the logs of the several groups may 5 be rolled off the scow one group at a time.

A further object is to provide for the bridle tighteners to act as Aauxiliary tighteners for .the

binding cables which hold the entire load in place on the'deck of the scow. 0 other objects of the invention wi11 in part be obvious and in part be pointed out hereinafter. To the attainment of the aforesaid objects and ends, the invention still further resides in the novel details of construction, combination 5 and arrangement of parts, n.11 'of which will be rst fully described in the following detailed description and then be particularly pointed out in the appended` claims, reference being had to the accompanying drawing: in which:-

0 Figure 1 is a. side elevation of a scow and logs that is the primary object of the present invenibodiment of the invention, I represents a scow of the usual construction to the sides of which,

in suitable supports (brackets) 5, onpivot pins 4, are mounted chocks 2 and pulleys 3. The

' chocks are held projected above the deck of the scow by chains 9 anchored to eye plates 8 rigidly fastened, in any suitable way, to the sides of the scow, the chains being in'sections connected by toggle hooks I0 so that the sections 9-9 of a chain maybe separated when it is desired to drop the chock as when unloading the scow.

B and 'I represent eye plates also suitably scmembers 6 and 'I the ends of the bridles Iii- Ille and Il--Ila are attached and to which the eye ends 2I and I6 of the tension hooks I 9 and I5 are connected. The tension hooks I9 and I5 include turn-buckles and I1, respectively, by means of which the bridles can be placed under tension.

'Ihe binding cables II pass around the pulleys or sheaves I3 and over the ends ofthe load, best shown in Figure l, a tensioning device comprising hookv bolts I3-I3, connected by a turnbuckle I2, being provided and located at any desired place in the length of the cable; for purposes on. illustration the hooks I3-I3 and turnbuckles I2 are shown located alongside the sco-W, although they might as 'well be located at the top of the load if desired.

As will be noted from Figure 1, the logs are laid to assume four groups, one mposed -of logs A being arranged in triangular form, a second group B being arranged in the form of va parallelogram along one side of the triangle, and the other two groups C andD being each arranged in the-form of a parallelogram side by side along the other side of the triangle.

In loading the scow the bridles I4-I4 are laid cured to the scow below ,the deck level, to which i along the deck of the scow, each to take in two Before tightening the bridles the binding cables Il are tightened 11m-then by tightening the When it is desired to unload the scow, the bind- I ing cable is slacked and released from the logs and the hooks I9-I5 are unfastened; a suitable -hauling line (not shown) is then hooked to the loop of the bridle I8, and, thechocks 2 having been first released., a/ pull on the hauling line will cause the group/of logs D to roll off the scow. The hauling line is thenhooked to the loop of the bridle I4 and group C is rolled off. The turn-buckles and I1 at the right of Figure 1 are loosened and the bridles Illa-I8a l5 are unhooked, chocks 2 atti/ie right are released, the haul line is hooked to the loop of bridle I8a and group B is rolled 01T. Then the haul vline is hooked to bridle Illa and group A is rolled 01T. I 20 Of course with scows on which logs are to be carried lengthwise eyeplates v6"-1X (see Figure 3) will be mounted on the sides of the scow and a single closed-loop c-able I I may be used by passing lit crosswise over the ends of the logs and around under the pulleys. Other changes in the details of construction and arrangement ofvparts can be made by those skilled in the art without departing from the spirit of the invention or the scope of the appended claims. What I claim is:

l. The method of transporting and unloading logs on scows which consists in laying the logs in tiers, arranging the logsin separate groups, providing. each outer group with anindependent bridle anchored to the deck of the scow adjacent the edges thereof, providing the inner groups with similar bridles likewise anchored to the 'scow adjacent the same edges, binding the entire load of logs to the scow as -a unit, then ten- 40 4sioning the bridles better to secure the load, and thereafter removing the binder and rolling oi the groups of logs by pulling on the loops of the bridles.

2. The method of transporting and unloading logs on scows which consists in laying the logs in tiers, arranging the logs in separate groups, providing each outer group with an independent bridle anchored to the deck of the scow adjacent the edges thereof, providing the innergroups with simil-ar bridles likewise anchored to the scow adjacent the same edges, binding the entire load of logs to the scow as a unit, then tensioning the bridles better to secure the load, and thereafter removing the binder and rolling ofi the groups of logs by pulling on theA loops of the bridles one at a time.

3. In log-transportation, a conveying means having an unobstructed load supporting surface on which logs are piled in tiers, said logs being arranged in groups, bridles anchored to the con-- veying means and embracing the respective groups, a binder cable engaging the conveying means and passing over all the logs to secure the logs to the'conveying means, chocks on theconveying means at the'sides of the log-pile, and.,

being divided into several groups of logs, bridles passing around the groups, meansto anchor the bridles Vto the conveying means at the margins of the conveying means, adjustable tensioning' means connecting the loops of the bridles to the conveying means atv the said margins, and binding means passed over 'the pile of logs and connected'to the conveying means for holding-the logs together to the deck of the conveying means.

5. In log-transportation, a conveying means having an unobstructed load supporting surface, releasable chocks extending above the deck level of the conveying means, releasable means to hold l the chocks elevated, a pile of logs on the conveying means between said chocksfsaid pile being divided into several groups of logs, bridles passing varound the groups, means to anchor the bridles to the conveying means at the margins of the conveying means, adjustable tensioning means connecting the loops of the bridles to the conveying means at the said margins,

binding means passed over the pile of logs and connected to the conveying means for holding the logs together to the deck of the-conveying means, and said binding means including a cable with means to place (it under tension.

6. In 'log-transportation, a conveying means having an unobstructed load supporting surface, releasable chocks extending above the deck' level of the conveying means, releasable means to hold the chocks elevated, a pile of logs on the conveying means between said chocks, said pile being divided into several groups of logs, bridles passing around the groups, means to anchor the bridlesto the conveying means at the margins of the conveying means, adjustable tensioning-means connecting the loops of the bridles to the conveying means at the lhaving an unobstructed load supporting surface,
