Serial No. 742,471.

To all whom it mag concern.

Beit known that l, FERNANDO HA TER- MAN, a-.citiz'en; of the ,-United States and resident of. .the.town of Oso, in the county of Snohomish and. State of 'VVashington, have -invented ,certain new and useful 1mprovements in Cableways,-of which the following. is a specification.

My invention. relates .to cableways, particularly those. which are. used for logging purposes, and it comprises the novel parts andcombinations of. parts which will be hereinafter, described and particularly pointed out in the claims,

Theobject of my invention is to provide a type of acableway particularly adapted for, logginggvhere the logs are oftthe large size found uponuthesPacific coast, with wh ch superior results may be secured without materiallyincreasing the cost of the apparatus and under which .planthe apparatus may,

- in some respects, belmadelighter and Emore flexible in use..

In the accompanying, drawings I have shownmy present preferred form.

Figure 1 shows, in plan, a :cableway made inaccordance witlnmy invention. Fig.v 2 shows thesame apparatus in elevation. Fig. Qty-shows, in elevation, arableway oflike character, except. that, the. outward run, of theshaul-back .line is carried alongside the trackway cables. Fig. et shows the carriage and trackway memberso-nv a larger; scale, omitting refinements of detailin; design. Figs; 5 and .6 are, respectively, side and edge elevations of the auxiliary carriage for thesnubbing lines, Fig. 7 shfowsthecar: riageconstructi'on for a single cable trackway. i Fig; 8: showsthe snubbing. line car: riage inedge view.

My invention is particularly designed for use inf-logging, although it possesses features which well adapt it for. other. uses. Lwill, however, describeit asemployedcin logging, it, being; understood that it nay be employed for otherpurposesandthat my inyention; lies in, the apparatus. andthe system, and not alone. in. the use to which t spnt-i The usual practice. ii -operating a cable wayzfor hauling out logs, employs the cablew ay, as set in any oneposition, for removing,; th,e.-logs lying i-uppn, a relatively narrow strip, such strip extendingfor a. distance. of approximately seventy five feet sat ,each' side of the cableway. Whilelogsmaygbedrawn in froina greater distance than this, if the logs are small, it is seldom, with the large logs found. inthe P acific coastsecti'on. of the country, thata. greater distance is covered at one setting of the cableway. One reason forthis limitation, is that hauling from a greater lateral distance brings an excessive strain upon the trackway cables. This is due largely to the fact that it requires, quite generally, a much greater pull to haul a log'out of the brush and debris of a clearing, than it does to bring itin after it has, been brought under the cableway. The lateral haul, except fora short distance near. the cableway, is a. straight drag over the ground, with W all kindsrof probable resistances due to engagement with roots,,stump s and brush, as well as thealways present digginginto the earth, and the friction due to the weight of thelog. When thelog reaches the cableway, its front end is always carried mostly, or entirely, clear of the ground, and at times, the en tirelog is carried ,upon the cableway. The result is that it will slide easily over any obstruction and the power required to bring it in along the cablewayis relatively small. It is, not difficult toprovide engine power and haulinglinesufficiently strong to easily oyercomethegreatest of these resistances, but. to. provide trackway cables of sufficient Patented Dec'.-9,1913,.

strength, meansexcessively heavy cables,

which means excessive costs and diff culties in movingand setting up. Theinability to work. at any great;distance from the line of the cableway, also;v means .morefrequent moving.

By my invention ,Lprovide snubbing lines Wl1iCl1,1"I1ay be brought. into use whenever desired, to take care ofthe side or lateral strains upon the trackway cables, whenever pulling in fromtheside. By thisexpedient I. so strengthen the trackway cables that they arev capable of standing'any lateral strain which, the hauling, line is capable. of enerting, therefore making, it, possible to haulfrom anylateraldistance to which it is jexpedientto take out-logs, without preparinga trackway therefor. This will reach as far as five hundred feet and may, insome leases, much exceed this. l In the drawings, 15' represents the head inastand 16the tail mast.

1,, 1, representthe two trackwaycables. Lhaveshown two cablesused as t-rackways, for the reason thatinthisway smaller cables may be used, these being easier to handle than larger cables.

I prefer that the trackway cables proper, terminate at clevises 10, or other means by which the cables may be broken near the head mast, so that the carriage may be easily removed. Extensions 11 extend over suitable supporting guides upon the head mast and are secured to tightening and takeup means, interposed between the mast and the anchorages 13, such means, as shown, consisting of blocks and line, 12. \Vhen putting up or taking down the cables, these will facilitate the work.

At the tail mast, 16, the cables 1, 1, are shown as extended to the ground and secured to stumps 1 1, Or other suitable anchorages. Guy lines 17 are also provided as needed.

The carriage 4 may be of any suitable construction. This has wheels 40, which run upon the trackway cables 1, and carries, or has secured thereto, guide pulleys 22 and 34: for the accommodation respectively of the haul line and the haul-back line.

The engine should have at least two drums, 20 and 21, drum 20 carrying the haul line 2 and drum 21 carrying the haul-back line 3. The haul line passes over a guide 23 carried by the head mast and thence to the carriage 4 and over the guide sheave 22.

As shown in Figs. 1 and 2, the haul-back line passes about guide sheaves 30 which are so placed as to conduct the haul-back line off to one side of the cableway and thence out along a line substantially parallel the cable way and then back to a point near the tail mast. This point may be somewhat short of the tail mast, as shown at 31. After passing about a course of this kind to the vicinity of the tail mast, the haulback line is carried over a guide pulley or sheave 34, carried by the carriage, thence to a guide sheave 32, which is shifted in position to suit the point from which logs are to be taken. This sheave 32 will be shifted to any point within the area of the tract covered by the cableway from any one position. This will include a strip of considerable possible size extending even back of or beyond the tail mast. The end of the haul-back line is secured to the end of the haul line, in order to be able to quickly take this back to the point where a log is to be taken from.

Passing the haul-back line through a guide sheave upon the carriage and then through a guide sheave upon the ground, gives three parts of the haul-back line which may be depended upon to hold the carriage against travel under the strain of the haul line. This makes it possible to strain the haul line up to its limit without advancing the carriage, should this be necessary in hauling out a log to the cableway. At the same time, the haul-back line may be kept light and therefore easy to handle.

The snubbing lines which I employ to take the side strain upon the cables, developed when hauling in from the side, are attached as follows: Upon the trackway cables are mounted, preferably, two auxiliary carriages 5, 5, these being placed one at each side of the carriage a. These are separate from the main carriage a, but are attachable thereto in such manner as, to be moved thereby along the cableway when this is desired. At times these carriages and their attached snubbing lines would not be needed and they may be left upon the cableway respectively near the head and tail masts.

To each carriage 5, 5, is secured a line of such length that it may be carried out laterally a reasonable distance and secured to a stump, tree or other object to resist the side strain put upon the carriage when hauling in a log from the side. At times, for small or moderate sized logs, only one of these snubbing lines need be used, but for large logs I prefer to use both.

A preferred form of carriage for the snul bing lines is shown in Figs. 5 and 6. This comprises a frame 53, which should have considerable strength and be provided with means, as eyes 52, to which the lines may be attached at each side, and wheels 50 adapted to run above the cableway lines 1, 1, and wheels 51 adapted to'lie beneath the trackway cables. The snubbing lines 55 should be attached to these carriages so that they may be detached and shifted to the other side, as by clevis 54.

The arrangement shown in Fig. 3 difiers from that described, only in providing guide supports for the outgoing part of the haulback line, alongside of the trackway cables 1. The carriage as shown in Fig. 4, has a guide sheave 33 for the haul-back line and the tail mast has a guide sheave 35. V

In Fig. 7 T have shown a form of construction of carriages adapted for use on a single cable trackway. The at has a single set of wheels 40 running'upon the trackway cables and wheels 22 and 34: for the haul line and haul-back line, respectively. In this case the cableway guide or auxiliary carriage which is used with the snubbing line, consists of a single wheel 50 and its frame 56, the latter being made wide beneath the trackway cable to permit its swinging toward either side, without necessity for any change.

It is immaterial, in my invention, that the exact means for attaching the snubbing lines to the cableway as herein shown, he used. The form of this attachment would be different in a two cable cableway from that for a single cable cableway, as has been shown. It may also vary for the same type of cableway.

What I claim as my invention and desire to secure by Letters Patent is:

main carriage 1. The combination with a cableway of a snubbing line having traveling engagement by one end with the cableWa-y, the other end being free and securable at will to any fixed object.

2. The combination with a cableway of a plurality of snubbing lines secured by one end to and extendible laterally from the cableway adjacent and at each side of the carriage, the other ends of said snubbing lines being free and securable at Will.
