Speclfieation of Letters l'atent. lApplication mea :une 29, 1911.
PatentedMar. 5,1912. serial no. eaaoao.
To all whom it may concern Be it known that I, CiIAnLnaE. MAoFAIb LANE, a citizen of the lUnited AStates, resid-` ing vat Portland, in the county vof Multnomah and State of Oregon, have invented new and useful Improvements in Logging of which the following is a specification.
This invention relates tov logging systems and consists in certain improvements in the' construction thereof as will be hereinafter fully described and set forth in the claims.
More particularly, the invention relates to a logging systemin which cables are used for handling the logs. Cables have been used heretofore for logging'purposes, the ordinary practice being to secure a heavy cable so as to form a-trolley support and then haul' the logs by separate cable to the troll'ey on this trolley support and then along the trolley' support to the point of delivery.
The object of the present invention is to Simplify a system of this type and at the same time add to its etiiciency.
v In the present system the cable which is used as a trolley support is also utilized in gathering the logs. For this purpose it is slacked and dcflceted si'dewise to the log and then drawn taut so as'toform acablesu port carrying with it the log, 'after which t e 4 log s run along this cable. form, theI side line which defiects the main line, may be also used as a hold-back fon the log if the cable is inclined. Under ditions, it is desirablelto provide a ho ffllck in the same vertical planewith thel main cable when taut so that the hold-back may operate sul'stantially in line with. the main cable. ln this instance, a third cable may be used. lt is also dosirablc to provide means whcreby the main` line may be quickly run to'a new` lead. p The importance of this'will be undm'stpod When it is considered that a large' part of the force .of men must necessarily be idle during this change of lead, and these lare of more or less frequency, quite a saving of time qan be affected when this change can be vquickly accomplished. This general outline gives a broad idea of the invention.
Ful-ther objects Will specification and claims.
In the simplest appear from the The invention is illustrated in the accompanying drawings as follows:
`Fignre 1 shows a* perspective view of a logging system, in whch four lines are used. Fig.'2 a perspective view of a logging .system in which but two of the lines are utilized.
1 marks the logging engine. lvided with a drum 2 for the main line 3. The main line is secured to a stub line 4 and this stub line is attached to a post 5, gnyed by the lines provided for the side line 8. This ektends through the pul- 'ley 9 secured to the post 10 and is attached to the 'trolley 11 on the main line.` The trolley'is provided with the usual hooks 12 b means of which the logs may be engage Where these two lines alone are used, or
`only two lines are used, the 'main line is slacked and deflectred by means of the' side line 8 so as to carry the trolley to the'log. After the log is attached, the main line is drawn taut carrying with it the log, the trolley is then run down the main line, the side lineS acting as a holdback. In some instances, the hold-back and detlecting` line may bedirectly in a vertical plane. p This is especially true where the logs are taken from a skid wa `as shown in'Fig. 2. I
It lis o enldesirable where a side line is used, as in Fig. 1, to provide a hold'baek 6-6, a tree being ordinarily. i used for the post A drum is This is p'odirectly in a vertical line with the main line thustgvng a more complete control to the trolley. The engine l-,is provided with a drum 13 from which the hold-back line. 14 extends passing through the pulleys 15 to the trolley 11. Where't-his is used, it is not necessary to use the linev 8 as a hold-back al-l though itimay act inl c'onpmction with the line 14-for-this purpose. `Or line v8 may be `attached to a separate block on the main line above the trollcy `11 and not travel up and down with the loads, but onl pull the main lineI 3 sidewise. r line 8 may be used as a pull-in line when there is not suilicient grade for the load to 4run by gravity. j
lin` order to make a quick shift of the lead of the main line 3, l prefer to provide a stubl line 4 withwhich the main line' is detachably attached by any convenient means. Where lthis is done, a second stub line 16 lbe used tol i I may be provided and this attached to a post 17, kthis post being guyed by the guy wires 18 and if desired, the lead changin line, 19
may be used, this being controlle by the drum 20 on the engine. The lead line is provided with a hdok 21 by means of which the main line inay be engaged and quickly moved 'to the new position. W'hen itis understood that the main line is of very heavy cable and very difficult to handl the importance of this quick shift will be realized.
, in the construction of Fig. l. The line is carried around the pulleys 9349:* and extends tothe trolley 11. In this way, the main line is detlected principally. in a vertical direction and the line 8a acts as a side line for deflecting the main line and aisa hold-back. 4*
With this system, logs may be quickly handled over rough ground, the leads quickly changed and the Whole operation is accomplish with a logging engie of general type. f
WhatI claim as new is:
1.'- In a logging system, the combination of a main line; a main line drum operating the main line; a trolley on the main line; a'
side line secured to .the trolley fordefiecting the main line to bring the trolley toa log; nd a side line drum for operating the' side 2. In a logging system, the combination of a main line; a main line drum operating the main line; a trolley on the main line ;a side line secured to the trolley for defiecting the main line to bring lthe trolley to a log; a mounting for said side line to adapt it to actas a hold-back for the trolley;'and a side line drum for operating the side line.
3. In a logging system, the combination of a main line; a main 'line drum operating the main line; a trolley on the main line; a stop on the main line for locating the trol- In this ley for deflecting the main line to bring the trolley to a log; and a side line drum erating the side line.
5.

6. In a logging system, the combination of a main line; a mainline drum for operating the main line; a stub line to 'which the for opmain line is detachabl attached; a trolley onthe .main line; a si e line. secured toL the' trolley for, defiecting the main line to bring thev trolley to a log; a side line'drum for operating the side line; a lead changing line for carrying the main line to a new lead; and a lead changing line drum 'for operating the lead changingfilipe. v
