Be it ltnown that liften 11a iirinnison 'Connn'r'iy of iortlai l., ititilnioinaii county, Urogon, have invented certain non' and uselul liniirovenients in Logging-Engines, oli which the following is speeiiention. l

.ln logging-engines as usually constructed two winding-drums are employed, one ior the matin or hziuling cable and the other lor the,

trip-line, which is ettnched .at-one end to the hauling/sable, for the purpose ol dragging it bank into the woods alter s. log hauled to the eng. e. The innin drinn, or the one on .if'nieh the werking estilo is wenn d, should have reat poner and be operated nt i, eoinparativey slow speed, while the nuxiliai y or 'trip line drum, having -no other lunetion than that oi'" dragging the hanlingwahle linut: into the woods, hws power, hut. should he capable of l'iigh speed to insurithe quiet; return of' the linnlingnil le nud 'l'aoilitate the drnwing in oi the logs. lt. is undesirable in obtaining the de." rat io ol' speed between the mein end e to. usen veri," large genr on. tlnzine..l t drinn with a sniall barrelv on ol the enhle, it np the auxiliary drum to the t or hauling ont thel trip-line and z de n drnin ot snilieient eepneity to tn f the trip-line, which e' vionsly iii-.ust he `4man ilo the length ol the, hauling-cable.

For the puriose l obtaining the desired of speed hetween the two drunis withe out increasing their dinnieter to an oltieetionthle degree various systems ol' eonipnnnd have been devised, which have generally been effet-,tive ns hir as regulating the speed of the drnnis is eoin'erued, lint have beenobjeetional)le on aeeonnt ot' the drunis operating in opposite direi-'ions and eoiling at least one ottheoablestroni the underside--Y n method whieli in nn appuiratus ot' this hind is very undesirable, as it necessitates tht` raising ol the drum in the trnine, causing a tendweakness, and iu ense 0l zt shit-.lt line nllows the cable tojdrag on other parts oll the inaohine. 'l`he gipsy head or wineh employed l'or supplenientary work should be mounted to overwiud its eoinparntiwi)Y small cable and he operated rapidly. 'llnIl overwinding oll the line vhas heen obtained by i inunting the wint-,h on the shatt ot the innin drum l; but the sneed .ot this shaft is too slow vl'or the work o the wine-h and hns nn excess oi' poner.

has heen i i i l l l i l i i i i l The objects, therefore, ot' my invention are to provide n logging-engine having main and auxiliary drums between which the desired ratio ol speed is obtained. without running into very large di nineters.

A ll'urther object is to provide drums operating in the saniedireetion and permitting their eahles to be wound over instead of under theni and the gipsy-wineh to be located on the high-speed-dru1n Shaft.

A further ohjeet is to place the drums as low its possible .in the traine, making the appli ent ion ol lall strains direet and overcoming the ohjeetionable leatnres ot' the ordinary niethod ol eonipound gearing without increasing the eost ol' construction.

'.llhe invention consists generally in various,

:constructions and combinations, Lall as hereinafter' described, and particularly pointed ont in 'the elainis.

ln the aeeonii'ianying drawings, lorining part ol" this speeitieation, Figure l is a pla-n view ot a logging-engine, the niain and auxiliar)r drums embodying niy invention being illustrated iu horizontal set-tion. Fig. 2 is a seetional `view on the line a' .r ol' Fig. 1., and Fig. l is a side ele\fation. v

ln the drawings, 2 represents a. suitable base or traine whereon n shalt 3 is journaled and operated troni the engines 4 in the usual nianner. 5 is a pinion keyed on the shaft 3 find meshing with a gear (i, secured on a shalt 7, hnving benriugs S on one side ol' said 'traine and on a bar t), extending lengthwise ol' said t`rni-ne,near the niiddle thereol". A elutehshoe l() ot' suitahle ninteriahsiieh. as woo'd,is seein-ed to the gear and has a wedge-shaped lare to enter a soeket l1, l'ornied on the head l2 ot n drinn 13, whieh is loosely mounted on said shalt 7 and is adapted to slide into engagei'nent with said eluteh-shoe, but norinally is held out ol eontaet therewith by a spring lil, eoiled about the said shalt be-- .iti ol'- gear G thereon. Allange in is provided on the head i7 at the opposite end ot' the drinn to reeeive a bi-alui-strap it), eonnerted with a shatt 2t), that `is roeked by a. lreadle 2l, loented within eonvenient rezu'h olv the operator. 'lhe druni is moved lengthwise 'on the shnl't to leek the l`ri t ion-eluteh by rotating a loosely-n1ounted toothed sleeve in engagement with a tixed toothed ring said sleeve hein-g operated lby a lever 21 o r other suitable means.

into the woods after a log has heen drawn in, The drum. having direct gearing with the Crank-shaft will operate at a high speed, and the lmuling in of the logs will he thereby greatly facilitated. One end of the shaft 7 projects heyondthe traine of the nntohine, and a Winch 22, generally called at gipsy,'. is mounted thereon and equipped with. n light line (not shown) 'for doing supplementary Work around the engine. This heed should revolve rapidly, and. its line should he over- Wound thereon., and hy .mounting it on the Shaft oi the high-speed drum 1 :im able to aocoinplieh both objects. Upon the forwurd end of the ber Q'i'roin the high-speed or tripline drum l provide e shaft .23, journnled in heerngson Seid har and on the opposite side of the freine :ind` Carrying on internal gear-ring 24, secured thereon. The shaft 7 extends within this geur ond is provided with e pin ion Zfnieshing therewith and through whirh and Seid internal gear the slietft- 223 .is driven at a slower speed. than the shett '7 the proper rat-io beingi obtained in the Wellduiown wn-5f'.
