Brace members or stays 91 are so KEG/(l at one end to one of the ring members 103 and at their other end to the tread member 100. approximately at the center of its width, such brace members being equally distributed around the circumference of the tread member. lVithin the housing is secured by means of brackets 105, a ring member 7 1 having; a double row of internal e'ear teeth 106 107. A pair of sleeve formed bearing members 51, are secured. to the beams 2 at opposite sides of the structure said ino' members having horizontally extentv perforated portions 49, adapted to be bolted to said beams, and having arms pr "tine; upward and forward from the horizontal portions 19, respectively. (see 1 12}. The inner ends of the sleeve poraons 31. 52 pass through central openings in the disks 108, around each of which openings is secured by means 0:? rivets or otherwise a two-part ring 108, 8), between which and the sleeves raceways formed for ball bearings 109, (Fig. The sleeve 5.1 provides a bearing: for one end of a clutch shaft 61, the opposite end of which has a bearing in the end of the crank shaft the outer end of the sleeve 51 being closed by a washer member 110 secured by means of screws to the sleeve, in which are inclosed roller bearings 111. between the shaft and. sleeve. A hanger bracket 58, provided with upturned ears 112 15th is mounted on the inner ends of the sleeves 51 52 and is retained thereon by mea: s of ri s so cured by screws to the sleeves. A n 'Jtor preferably of V type is seated in this hanger and secured. thereto by means of bolts. The motor flywheel 11 1 and the usual. spring pressed dislr. clutch 113 are mounted respectively on the shafts 135 and 61 between the motor and one of the ears of the hanger.

For transmitting motion trom. the motor to the housing a inion 63 is splined the shaft 61 and is in mesh with gear 71 which extends through an openi .115 formed in the sleeve 51, (seel? 12), and wh u 71 is fixed to a sleeve 72 that is '7 and rotatably mounted on a shaii e7 secured at its ends in the ends or the angular brackets 56 formed integral with the sleeves 51, 52, (Fig. A pair of gears 75, 76 are loosely mounted on the sleeve and are adapted to mesh respectively with the internal gears 106, 107 carried by the member 74- for high and low speed respec tively, the gears 75, 76 being preferably provided with roller teeth, as shown in Fig. 3. The sleeve 72 is provided with a plurality of keyways in which are adapted to slide keys 116 secured to a grooved collar 117, (Fig. 6), which is adapted to receive a yoke for shifting the gears. The keys 116 are provided with projecting keys 11.8 adapted to slide within keyways liormed in the gears and 76. by means of which when the collar 117 is slid, for instance. toward. the left as shown in is. 3. the keys 118 will engage the lowspeed g ar 76, whereby the member 7 1, and thereby the entire housing, is rotated at low speed while when the collar is shifted toward the right the keys will slide out of enga ement with the low-speed gear and into e agement with the higlrspeed 7 5, thereby causing rotation of the housing at high speed. The sleeve 72 has also formed therein a groove 1. 9 for engagement with a suitable yolze for sliding the gear 71 out of mesh with the pinion 63 when it is desired to reverse the tractor, or for permitting the use oi? the motor for doing other farm worlr while the tractor remains stationary. Suitable means is provided for 1 versine' the direction or? movement of the tractor. In the present in stance this means comprises a il-shaped manber 78. one of the of whicl'i is ".ieunt in an opening; in a lug 79 formed on the sleeve 51. the other leg; carr ing a double pinion 77 adapted to mesh wih the pin on 63 and the gear 71 when the latter is shi "ted out of engagement with the pinion whereby reverse motion inu'iarted to the tractor. .The double pinion 77 is normally held out of mesh with the pinion (59 and gear 71 by means oil? a spring 80 attached to a bracket 81 secur i. at a suitable ")lllt on the sleeve This U-shaped shitting: lever 78 isoperated by means or? a cable that e7;- tends over pulleys suitably n 'ited within the housing.

T ie opening 82 in the sleeve also permits the passage of the water and intake pipes 8+1. o5 and 86. A. pair ot il-shaped channel members 18 are secured to the side beams 2 or the frame and form a support for the hood 17 and gas tank 16. Fig. 1).

The trout wheels are attached to the frame hereiube'tere describ d for vertical adjustment and also for ad ustment as to width. Referring now particularly to Figs.

1 and2, a pair of depending brackets 5 are secured to the front end of the frame and carry at their lower ends bearings in which is mounted a shaft 6, on which are slidably and rotatably mounted a pair of sleeves 7, which are held in adjusted position by means of collars 7 clamped to the shaft 6 by set screws, as shown in Fig. 2.

Each of the sleeves 7 carries a forwardly extending rod or arm 8, the opposite end of which is secured in a second sleeve 9, that is slidably mounted on a shaft 10 which forms the front axle of the truck and carries a pair of ground wheels 11. The sleeves extension of the plate 3 and is supported at its lower end on a cross bar 12 secured at its ends to the arms 8. At the outer end of each of the sleeves 9 may be mounted a spindle 15 carrying a pulley 16 approximately midway of its height around which passes a cable 47 that extends back to the steering wheel at the drivers seat whereby the front wheels are steered. A vane 17 may be mounted at the upper end of the spindle 15 to indicate to the driver that the front frame has properly responded to the movement of the hand wheel. The usual radiator 70, fan 69 and water tank 64: are mounted on the front end of the frame 2. The fan is operated by means of a belt and pulley connection 68 with a shaft 67 carrying at its rear end a bevel pinion 66 in mesh with a bevel gear secured within a pulley 62 mounted on the end of the shaft 61. The pulley 62 is for the purpose of connecting a belt thereto whenthe tractor is held stationary and the motor is to be used for do ing other work.

The rear wheel carrying structure as hereinbefore stated, is mounted for both vertical and sidewise movement relatively to the main frame. For this purpose I have provided a rear frame comprising a channel-shaped cross bar 26, to the ends of which are secured a pair of extension members 32 provided with a plurality of bolt holes for permitting adjustment of the length of the members 32 on the cross bar 26 whereby the distance between the rear wheels may be varied for road work or plowing. The members 32 are pivoted at their outer ends to a pair of channel-shaped members 29, which are pivoted at their opposite ends to a pair of brackets bolted to the side bars 2- of the main frame, a plurality ofbolt openings being formed in the side bars whereby the members 29 may be adjusted along the side bars 2 to correspond with the adjustment of the extension members 32. At the rear ends of the members 29 are pivotally mounted a pair of depending members or standards 130 (Fig. 1), carrying at their lower ends trunnions 131 on which the wheels 85 are mounted. Suitable supporting braces or stays e8 form bearings for the lower ends of the members 130 and are secured at their opposite ends to the members 29. For permitting the rear wheels to be steered independently of the front, the upper ends of the members 130 are provided with a pair of radial arms 132, to the ends of which are pivotally connected a rod 40. A pair of bars 35, one at each side of the frame, are secured at one end to the cross bar 26 and carry their opposite ends a bar 3%, the bars 34: and 35 forming a framework on which is mounted the drivers seat 36 and the attachment-operating levers 37. A shaft 4a is mounted in bearings carried by the bar 34; and the cross bar 26, and on this shaft is secured a chain wheel or sprocket 2, which is connected by a chain 43 to a chain wheel carried on the shaft of the hand wheel A l. The shaft 4E1 carries a bell crank which is connected to the steering rod 10. The hand wheel shaft also carries a worm adapted to mesh with a worm gear which operates a spool 46 around which the cable 4-7 for steering the front wheels is wound. The chain 43 may,however, be removed from the sprockets and the rear wheels left to be shifted by a foot lever if so desired. For locking the rear frame to the main frame I have provided a T-shaped member 24, (Fig. 10), which is pivotally mounted on the end beam of the main frame and having the portion 133 thereof extend ing through an elongated slot 134 formed in the cross bar 26, a roller 25 being mounted onsaid portion 133 for engagement with the upper and lower walls of said slot, as shown in Fig. 1. An upright spindle 27 provided at its lower end with an eye is pivoted on the outer end of the portion 183, said spindle passing through the connecting plate 4: and having mounted thereon a pair of cushioning springs 28 in a manner similar to the spindles 13 at the front end-of the machine. By this construction the rear frame may be maintained against sidewise movement relatively to the main frame by inserting a pin through openings formed in the flanges of the channel bar 526 at each side of the roller 25, thereby preventing the roller from moving sidewise in the slot. A pair of channel formed brace members 20 are secured to the rear portion of the main frame and extend rearward and upward at an angle thereto and carry at their outer ends a pair of uprights 21 for supporting the hand wheel let and the gear shift and clutch levers 22 and 28. l. framework 38 is secured to the cross bar 26 for attachment of various farm implements, as for instance listers, plows or Cultivators, the latter being illustrated at 39, all of which may be suitably connected with the levers 37 for operation from the drivers seat. I prefer to use in connection with the tractor describedthe treads 88. Such treads, however, form no part of this invention and are described in my contemporaneously pending application, Serial No. 268,152, filed December 24, 1918.

From the foregoing it will be seen that I have provided a machine in which the motor is mounted in such manner that its bearings may be adjusted, by releasing the bolts or screws that clamp the hanger bracket to the sleeves 51, and shifting such bracket around its axis to the desired position, the motor having been first disconnected from the gas, water and intake pipes and such pipes reconnected to the motor in its adjusted position. It will also be seen that the motor and the driving mecha nism are mounted in parallel relation aXi ally thereof, whereby a better balancing of the weight of the engine is obtained and less strain on the frame is produced when power is applied. It will also be observed that I have provided in this machine a novel means for changing the gears, and while I have described in detail the structure herein illustrated, it is to be understood that I do not thereby limit my invention to the precise features of construction shown, as I am aware that many mechanical changes and modifications may be made therein without departing from the spirit and scope of the invention as set forth in the claims hereto appended.
