To all cohort it mat/concern Be it known that I, JOHN'D.

resident off-Jacksonville, county of Duval,

and State of Florida, have invented certain new and useful Improvements in Timber- Felling Apparatus, ofwhich the following is a specification.

This invention relates broadly to tree-fell- 1U ing apparatus, and more specifically to a sawing mechanism for use in timber-felling V operations.

The primary object of the invention is to' provide a power-driven apparatus, designed especially for; use in conducting extensive timber-felllng operations, by means of which trees included in relatively large areas may be felled successively without shifting of the power mechanism."

A further objectis to provide a sawing apparatus by means of which the felling of timber may be accomplished expeditiously and with a minimum of-manual manipula tion.

A still further object. is to provide in a device of the character .mentioned, a saw structure which is particularly eflicient in the cutting of timber.

With these and other objects in view,vthe

invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accom-- panying drawings,'-in 'which I Figure 1 is a view illustrating the application of the invention; p

Figure 2 is an enlargedsid'e elevation of a length of the saw; v

Figure 3 is a section on line 33, Fig. 2. 4O

longitudinal section and partly in side elevation;

Figure 5 is a side elevation of one of the sections of a modified form of the saw; Figures 6 and 7 are opposite end elevations of the same; and

Figure 8 is a view of the flexible coupling of the saw sections showing one of the latter coupled to a cable connector, said connector being shown partially in longitudinal section.

Referring to said drawings, 1 indicates a flexible cable which has its opposite ends wound upon reversible drums or a drum, as

2, of an engine (notshown) which may be Figure 4 is a view of the same partly in v I 1 of the usual 'slzidder'typei Carried inter-- WILSON, a citizen of the United States of America, and

mediate the ends of saidcable is a saw composed of a'plurality of flexibly related sections and which is 'designed to-be forcibly 3 drawn back and forth in engagement with JACKSONVILLE, rLoaIDAjAssIenoa or lonnnanriro 1:11

the. trunk of a standiiwitree for routing its way throughzssaid trunk. a v a I v a In the formiillustrated in F igsil to 4;,' the-= saw 1s composed of a plurality of sections designated generally by'rthe reference char= acter A. Each of said sections comprisesa' cylindrical sleeve 3 of metal, preferably tool steel, having integral radially extending teeth 4 arranged in annular-rows and constitutingspike-like cutters or router teeth Said sections are preferably 'made ofishort;

V are provided between the adjacent-sections,

length, as" about three-inches; and ar'ejem 'ployed in therequired'nuinbe'r aroma to allow the cable upon which'said sections) are mounted to bend to the exte'nti that-any cent sectionsmay be assumed; The saidsections of the saware required degree ofangularity between adja-Q mounted' 1 rigidly upon the cableina'ny suitable manner. As shown in 'Fi'g. 4, the opening through-the sleeve 3 is made of relatively inposite ends and "a'filling 16 of a suitable"? creased diameter at and, adjacent to itsflopl the spacebetween' said sleeve'and the cable, 7

serves to secure the I saw; section against movement on said cable; Similarly,'a' memher 5 is mounted upon the cableadjacent to each end of'the saw, said member "being of i conical 'form and designed to deflect the I endsof said saw to positions wherein, when the cableis being rapidly advanced in either direction in contact with a tree trunk, only the ends of the teeth will engage said trunk,

. thus obviating the violent anddamaging impactsvwhich would result from the broadside striking of the ends of the saw against such trunk. To further secure said saw sections and the deflecting members 5, to the by introducing beneath the outer strands thereof slugs of metal 15,. said swells being posed with the teeth thereof in staggered relation for facilitating the cutting,it being cable, swells 14 may be formed .on thel'atter designed that, through the thereby-produced kerf, the operating teeth of each saw section shall rout out the space or spaces omitted by the longitudinal rows of teeth of the section next in' advance thereof.

In the modification illustrated in Figs. 5 to 8, the saw constitutes a splice or coupling for the adjacent ends of a cable 1 and is composed of coupled sections A which are not directly mounted upon the cable. Each section A" comprises a cylindrical body 3 having teeth 4; Said body has a stem portion 6 formed on each end thereof, and provided in said stem are two round diametricjally disposed holes ,7 and v8 which are directed at right'angles to each other. Said holes have received therein the ends of links 9 and 10 which together constitute auniversal coupling between adjacent saw section sjA and also between the end sections and stems 11 formed upon the ends of conical members 5? which are attached to the cable 1 practice, the cable having its ends wound upon the drum .or drums of the engineer other power mechanism is initially disposed, as shown in Fig. l, to encircle a definite' area of operation within which may be locatednumerous trees 12 to be felled and with the saw located in a position to be drawn back and'forth with respect to one or more of the areaenclosed trees with the reciprocatory movements of the cable effected by operation of said drum or drums. The cable is either passed around trees located on theborder of said area, or, in order to reduce frictional resistance, it may be Pa sed Oyer pulleys 13 attached to said trees, as shown at the right in Fig. 1. As trees are felled, the area of operation is reduced gradually until all the timber within the same has been prostrated, the working position of the saw be ng shi ted f m time t time s required to efiect proper positioning thereof.

is claimed isv1, ,I-imber felling apparatus comprising, in com ination with the reversible cablewinding drums of a power mechanism, a cable having its ends wound on saiddrums, and a saw carried by said cable, said saw being formed of a plurality of members arranged io allow relative angular adjustment, each memberbe ing of cylindrical form and having radially disposed teeth.

2. Timber felling apparatus comprising, in combination with the reversible cablewinding drums of a power mechanism, a cable having its ends wound on said dru s, said cable'being adapted to enclose a timber bearing area,' a'saw interposed in said cable, sa'id saw being formed of 'a plurality of flexibly related cylindrical sections having radial teeth, and conical deflecting members located adj acent to the end sections of the saw. .3. In timber felling apparatus, a flexible cable, and a saw carried by said cable, said saw comprising a plurality of sleeve members fixed on said cable, and teeth formed annularly von said members.

4. In timber felling apparatus, a flexible cable, and a saw carried by said cable, said saw comprising a plurality of sleeve members fixed on said cable, said members being located in spaced relation to allow relative angular adjustment thereof, each member being cylindrical in form and carrying radial annularly disposed teeth.

In timber felling apparatus, a flexible cable, and a saw carried by said cable, said saw comprising a plurallty of sleeve members ,fixed on said cable, said members being located inspaced relation .toallow relative angular adjustment thereof, each member being cylindrical in form and carrying radial annularly disposed teeth, and conical members carried .by said cable adjacentto the opposite end members of said saw.
