is 'a top view of t e upper frame with some I atented March 2, 1909.

providinv bearings for the main driving shaft.V t the forward end-` Of the frame 1 and at the vrear end of lthe frame 2 res ectively, the 4front live axle 6 and the rear ive 60 axle 7 are journaled. The rear driving wheels 8 are -xedly mounted upon the live axle -7 While the front drivmgf'wheels 9 are rotatably mounted upon the axle '6 and have ratchet'connection 't erewith as hereinafter'er morevfully described.I The frames 1 and 2 taper toward their point of pivotal connec-r tion and the said pivotal 'connection consists of a casting V10 provided with ,a rearwardly extend-ing floke portion 11 within which l1s arranged t e casting 12 having the projections 13- ada' ted to en a e sint'able a er- P g P tures inv the upper and ower sides-of the yoke 11..'1 rThe casting 12 extends through the rear frame t0 the cross piece 4 whereit terminates and it is also drilled axially throughout its length at 14 for the accomv[mod'ation of the main driving shaft ashoreinafter described, Upon the front frame is' `mounted a 'circular track-like,4 bearing 15 provided with a groove 16`in its up er surace adapted to 'receive a circular caring track 1 7 mounted upon the' lower side ofthe' uppTer frame, 'on the fron-t axle 6 is xedlymounted the eveled gear 18, which meshesl with the beveled ear l19 fxelly 'mounted'u on the extreme v ront end of the driving shafit). The v main drivingl shaft consists of two portions, theforward and the rear portions 20 and 2l l respectively which are ,connected to each other by means of a universal joint at the oint 22 inthe axis of the pivotal .connection etweenthe front and rear frames jl and' 2,.1

' portion 2 1 is journaled in the casting 12 and also in a sleevey 24, which in turn is rotatably mountedwithin a bearing on the cross piece 5 of the frame l2. Besides the gear 19 the forward shaft is provided with the beveled ear 25 which is xedly mounted uponsaid s aft and meshes with the beveled gearx26 yfor the purpose hereinafter more lfull disclosed.` .The rear shaft 21 is provided with `'a feather key 27 which secures. the lmovable...clutch head 28 against rotation upon thesaid shaft while Y permitting vsliding vI novfolfncnt of th said head upon the said shaft. "f

' .Th e forward end of the sleeve 24 liii/pri)- v'ided with. what 'may be termed `a relatively i so with a well known form of ratchet construcbrac stationary clutch head 29 adaptedto be engaged by the sliding clutch head 28 when the 4 same is moved to its rearward position. The beveled gear 30'is also ixedly mounted upon the sleeve 24 and meshes with the beveled' gear 31, which is xedly mounted upon the rear live axle1 7 and is intended to produce rotation of the axle 7 when the sleeve 24 is caused to rotate. The detailed construction ofthe clutch heads 28 and 29 is immaterial except that the clutch should be a positive one and such clutch is shown in the drawings. Uppn the cross piece 4 is arranged the et 32 to which is pivotally attached the 'clutch operatin lever 33, which lever is provided with a y0 e portion encircling the clutch headand pivoted theretoin the usual Well known" manner and to which lever at they point 34 is pivotally attached the connecting v rod 35 which extends rearwardly and has pivotal connection with the hand 'lever 36 whereby the clutch head 28 may be thrown into engagement with the 'head 29 for the purpose of rotating the gear 30 with the shaft 21 when so desired.

The front wheels 9 are provided with substantial hubs 37 which are provided on their i inner'faces with an annular series of notches 38,v the said series being arranged concenrftrically with the axle 6 and in accordance tion wherein one side of the notch is deeper .which are; ixedly mounted'upon the livey axle 6 and are provided with an enlarged. portion forming the pin and spring housing 41. The said'` housing is arranged immediately loppositethe annular series of notches and upon th'esidev next to the hub is open. to permit the pinl 39 to engage-the said notches` while at the opposite end of the housing an opening 42 equal to the diameter of the pin 39 and also radial slot like extensions of said opening 43 are provided. The pin 39 is provided with a head portion as shown and also with the spring-engaging lugs 44 and 45 be.v

tween which is arranged the coil spring 46. The arrangement of the device is clearly illustrated in Figs. 5, 6 and 7 where it will be seen that vthe pin and spring are located Within the housing of the disk 40 with the inner end of the pin engaging thenotches 38. The one end of the coil spring engaging the lugs 44 1 and the other end bearing against the partially closed end of the housing will force the pin against the faces of the notcheswhile the f lug 45 .is located within one of the `slots 43. lf now the head of theppinbe drawn away from the disk 40 so as to disengage the point of the pin from the notches and/the said pin be given a quarter turn the lug45, having been lifted out of the slot 43, will bear against the outside of the housing 40 adjacent the aperture 42 and will prevent thepin from again coming into engagement with the notches 38 until such time as the said pin is again turned so 'that the lug 45 may enter the slot 43, all for the purpose hereinafter more fully disclosed. i Upon the front live axle 6 is iixedly mounted the disk 47- provided with a radially.

notched face 48. Rotatably and slidably mounted upon the said front axle is the drum y 'i 49 providedat the end adjacent the disk 47 with the integral clutch'member 50 having radially disposed ribs adapted for engagement with the notches in the face ofthe disk 47, the disk 47 and the clutch member 5() being adapted to co-act to cause the drum 49 to rotate with the axle 6 whenv the drum 49 is moved along the axle 6 until the said clutch member and disk engage each other.

4For the purpose of controlling the sliding movement of the drum 49 along the axle`6 the lever5l is provided which is pivoted to 'the cross piece 3 at the point 52 and also has pivotal connection with the loose collar 53 upon a reduced portion of. the drum 49 in accordance withthe method commonly employed in the control of rotary clutch mem.

bers. It will be understood that by grasping the lever 5l with the hand and moving it.

to vthe right or the left the drum 49`will be moved along the axle 6 and the disk 47 and the clutch member 50 caused to se arate from orengage each other as desired y the operator.

Fixedly attached to the forward and rear frames are the laterally extending arms 54 and 55, which consist of upper and lower members as more clearly illustrated in Fig. 8 and between the up er and lower members of eacharm is pivota ly mounted the yoke 56 ywhich in turn carries the transversely pivoted knuckle sleeve571 which is internally screw threaded for the accommodation of the screw threaded spacing rod 58. The knuckle sleeves upon the two arms are right andleft threaded vvith res ect to each other and the s acing rod 58 isl vleft threa ed so that when the rod 58 is rotated in one direction the ends of the arms ikewise right and 54 and 55 will be brought closer together whereas if the rod 58 is rotated in the opposite direction the ends of the` arms 54 and 55 will be farther separated from each other. It' is obviousthat the result of the relative movement between the arms 54 and 55 will be to give pivotal movement as between the forward and'rear frames 1 and 2 and thus providel means for 'guiding the traction engine. I

For the purpose of controlling thel rotation y of the r'od 58 the steering rod 59 is provided.

The steering wheel 60=is 'xedlymountedupon the upper end ofsaid rodandthe universal jointdl, .connects the other end ofthe steering rodywiththe end of the spacing rod rod'59. The sai steening rod 59, itsh'ould be` 58. Upon thefra'me 2 is mounted a'bracket 62 within which is vertically pivoted a yoke 63. which carries tho transversely pivoted sleeve 64 throu hA which runs the steering to be hereafter ldescribed areA readily im-.. vessible.

Mounted upon the. cross piece 5 of the frame 2 isa roller support 66, provided uv ith two upwardly extending yoke pieces 67 and 68 beta een which is rotatably mounted the transversely disposed roller-69, said roller being of less diameter at. its central portion than kat its ends as shown in the drav. ing, and for the purpose hereafter described.

The up r frame 70 is of the general lform illustrated)e in Fig. Sand is constructedof 'I beams and'channel iron and upon the lower side near its forward. end is rovided with the circular bearing track 17 a apted to engage the groove 16 in the'upper surface of the bearing 15 upon the lower frame. At the rear end of the upper frame is an extension or tail piece 71 vhich is substantially round in cross section and is provided at its rear extremity u ith the lever-base portion 72. The said up er frame is adapted to be placed upon the orward and rear frames 1 lso and 2 with the' bearing .track 17 mounted upon the V bearing 15 and the tail piece 71 upon the roller 69, which roller is reduced in diameter at its central portion for the pur-l pose'of more'securely holding the tailpiece in position upon it, and if desired la reversed U shaped band, notshovwn in lthe drawings, may extend from the yoke piece 67 over the to of the tail piece 7 1 and to the yoke piece 68 t us providing additional means for holdingthe said tail piece against displacement. j

n Upon the upper frame is mounted; the source of power for driving the traction'engine, preferably a gasolene engine as illustrated in the drawings. The -said engine should be so disposed that its crank shaft will extend across the upper frame' as illust-rated andthe' said crank shaft should be provided with the gears 73 and 74 at its opposite p ends. Fixedly mounted uponthe upper frame are the counter-shaft sup orts 75 'and 76 provided with boxes in whic 1 the counter-shaft 77 is journaled. The said counter-shaft is provided at each end with a gear, the gear 78 adapted'to mesh with tho gear 78 and the gear 79 adapted to mesh with the gear 74 when the counter-shaft 77 lis slidably adjustedv to bring the respective pairs of' gears intoengagement with each other. l lhe gear 73 is spaced from the gear `74 a certain distance and the length of the counter-shaft 77 is such that the distance between' the gears 78 and 79 isjsuiliciently less than the distance between the gears 73 and 74 sothat by slidable adjustment of the counter-shaft 77 the gears 78 and 79 may be thrown entirely out of engagement with the gears 73 and 74 or the gears 78 and 73 or the gears 79 and 74 may be thrown into engagement as desired. The gear 7 3 isof less di amete-r than the gear 78 and the gear 74 is of v I greater diameter than the gear 79 so thatpby the slidable adjustment of the counter-shalt 77 greater power with less s eed or less power with greater speed may e communi-y cated to the counter-shaft trom the crank v shaft of the engine.

Loosely mounted upon'the counter-shaft 77 is the collar 80 held in place against longitudinal-4 movement on said shaft by thc stationary collars .8.1 and 82. The collar80 is provided with pins, 83 which are engaged bythe yoke portion of a bell crank lever 84, which is pivoted to the upper frame at 85. Pivotally attached to the other vend of the bell crank lever is the connecting A rod 86 which extends rearwardly and is guided by a pivoted link A87 to the lever 88, which lever is mounted upon the lever-base portion 72 of the tail piece 71.` It Will be understood that the collar 80 and that by manipulation of' the llO lever 88 the bell crank 84 will be so operated as to move thesha'ft 77 longitudinally within its bearings so as to throw the same out 'of gear with the engine or to throw either'the gears 7S and 78 or 74 and 7 9 into engagement with each other as may be desired. l

The sleeve 89 is slidably mounted upon the counter-shaft 77 and held against rotation on the same by means of the 'feather key 90 which extends throughout the length of the said 'sleeve and for a short distance beyond the same. Upon the. sleeve 89 areA ixedly mounted the beveled gears 91 and 92 adapted" for engagement with the beveled gear 93 to be' hereinafter more fully described. The

-collar'94 is rotatably mounted upon the sleeve 89.but held against longitudinal disi placement by means similar to that in the.A

case of the collar 80 just described. Pins'9'5 are provided upon the collar 94 which pins clutch member 105 is slidably mounted upon the bell crank lever the connectin arcfengaged by the-yoke portion of the bellf crank lever 96 which is pivotally attached to the upper frame. From the other side of y rod 97 guided by the pivoted link 98 lea s to, the lever 99 mounted upon the-lever-base portion 72 and pivotal connection isprovided with the rod 97 and the lever 99"so that by manipulation of the lever 99 the bell crank lever 96 may be caused to'move the sleeve 89 longitudinally in either direction upon the counter-shaft 77. The beveled gears 91 and 92 are so spaced from eachother that either one or the other of said gears will bein en-` gagement with the gear 93 and so that both gears can never be in engagement with the said gear 93 at the' same time. It willigbe obvious that while the counter-shaft77 is rotating in a given direction n'ianipulation' of the lever 99 will throw either the gear 91 or A92 into engagement with the gear 93 and that the direction of rotation of the gear 93 will depend-upon which of the'two gears 91 or 92is in engagement with it.

In the axis of the circular bearing track 17 and of the bearing 15, and above the plane of the upper frame is the stationary sup orting collar '100 which forms a bearing orl the, hollow stud u on which the gear 93 is mounted. This collar is supported from the cross pieces in the upper frame by means of integral brackets as mostfclearly illustrated in vEig. 4. The gear 93* is mounted upon or formed integrally-with the hollow stud 101, which has a friction clutch face 102. Within the hollow portion of the stud 101 is journaled thev shaft 103 which also hasa bearing at 104 and is provided at its lower end with the fixedly attached gear 26 meshingfwith the gear 25 as before described. rlhe lower the shaft l103 andwis held against rotation on said shaft by a feather key, 106. A. rotatable collar, 107, provided with pins, 108, is" arranged upon the lower clutch Ymember and the bell crank lever 109 is provided with a oke ortionat one end which is in en a ement with the said lpins.

The bell crank lever 109 is pivoted to the upper frame at the point 110 and'at its other end has pivotal connection with the connecting rod 111, which extends rearwardly over the top of the upper-frame, and is guided by the pivoted link 112 to the lever 113 mounted upon the lever-base portion 72 and with which lever it has pivotal connection so that manipulation of the said lever will move the connecting rod 111 longitudinally, thus operating the bell crank lever 109 and bringing the -lower clutch member 105 into engagement with the clutch head 102.

stood that while the counter-shaft 77 is lt will be under- "lk rotatingv and one ofthe gears upon said `sh'aft is in engagement withl the gear 93 so as to cause 'the said gear together with the hollow stud 101 to rotate-*the lower clutch' Y member 105 may be thrown into engagement with vthe clutch head 102 thus producing rotation of theshaft 103 and the gear 26.

A device of the kind herein described being rovided, the operation of the same is asv xollowsrThe engine having been started power may be communicated to the counter- I shaft .7 7 through the intermediate gears Aand by manipulation of the lever 99 the appropriate gear upon the sleeve 89 may be thrown into engagement with the gear 93. supposed that the direction of rotation of the gear 93 is appropriate for the forward movement of tne tract-ion engine, the lever 36:

should be manipulated to throw the clutch heads 23 and 29 into engagement andthe lever 113 should be manipulated to -throw the lower clutch member 105 into engage-- ment with the clutch head. 102. This will roduce rotation of the gear 26 which will lie communicated to the gear 25 and produce rotation of the main driving shaft 20 and 21, rotating the gears 19 and 30 at theA extreme ends of said shaft and communicating'pwer to all four of the driving wheels. This will produce a forward movement -of the traction engine whereupon the same may be guided in the said forward movement by 4means of apppropriate manipulation of the' steering w leel 60 causing pivotalmovement between the forwardvand rear frames land 2. In the pivotal movement of the forward and rear frames the bearing track 17 will be extent transversely or obliquely upon saidv roller. p

One of the most important features is the use of the drum 49 in cases where excessively `'heavy draftis required or where it is desirable to block the traction engine against Let it be i movement' and use the said drum 49 as a winch in logging or moving heavy objects.

ln usin the drum 49 the lever 36 should be n manipu ated to disengage the clutch headsv ment with the clutch head 102 a reverse rotation of the front live axle 6 will be produced through the operation of the intermediate ears. The live axle 6 rotating in reverse irection will cause ,the clutch pins 39 to ride upand slip over the beveled notches 38, thus 5 producing no rotation fof the front driving j wheels. The lever 5f may then be thrown to bring the clutch member 50 into engagement with the disk 47 producing rotation of manner wellknown in the art of using similar devices whereupon the drum 49 will prove a very powerful and efficient winch.

It should be understood that although the drawin s do not show a differential gear upon tlgle rear axle ,'suc'hgear of any well known patternjshouldbe used to produce a more efficient device. ,v Such gears are in common use upon similar constructions and such gear is not herein shown or claimed.
