To all whom it mciy conccrnr -Be it known that I, EvnnHYsuN, a citizen of the .United-States, residing-al- Kindred, in the county of Cass and State of North Dakota, have invented a new and useful Improvement in Automobiles of which the following is a specification. I

This invention relates to a supporting steeringor driving gear formotor vehicles, embodying a four who 1' drive in which the power is at all times applied equally to all fontwheels, and in which both axles or all four "wheels are used in steering.

The advantages of the invention are that slipping of the drive wheels on muddy or sandy roads, or in hill climbing under high power, is prevented to a large extent, as well as skidding or side slipor slipping on sandy roads, or when running on an incline or in making abrupt turns. p r

1 Other advantages with respect to eonstruction and lightness of parts, direct driving, and quick and eflicienqstyering, will be apparent from the following deseriptionand the drawings.

In the ccornpanying drawings, Figure l-is horizontal sectional view of the gear. Fig. 2 is a side elevation.

Fig. is a section on the line of'Fig. 1. Fig. 4 is an elevation showing the means for tr'ansniittinglhe power from theTha-n'ge speed mechanism to the drive shaft. Referring specifically to the drawings, A indicates a longitudinal drive shaft carried in a housing whichextends lengthwise atithe-middle line of the gear from the from mine rear axle. This shaft is'forrned in two sections connected by a differential gear L properly located for a Convenient driving connection with the en gine, and said shaft has at each e ndfa bevel pinion a which engages a larger bevelgear' disk B which is set in the shai casing R and engages a bevel gear on the outside 'offh differential gear 0 onthe divided sections of the drivng axles S. The shaft casing is tubulahas usual, with a casting. or housing R at the middle, of

proper shape and suflicient body to support the gears referred to.

The drive shaft casing 1) forms a reach between the front and rear axle casings and is provided at each end with a fork d the upper and lower branches of which embrace therebetween thehousing R of the axle cas-' ing'which is pivoted therein by pivot studs or tr m nions r fittingin appropriate recesses inthe branches,

- and preferably with ball bearings 0 between the housing and the fork. The housing R is slotted as at-rf where the shaft A passes through, to allow the turn incident to steering, and the slot'is covered by flanges-d which-fit close and cover the. slot in all positions, mak-' ing it dust and oil proof.

In advance of the middle of the reach D is a trapsverse horizontal tube E, which is preferably integral rotated by means of a wornr wheel Gthereon engaged by with the reach, and contains a steering shaft F which is :Speeification of-Letters Patent...- Application filed April 9, 1907. senn No. 387,182

Patented S ept. 10, 1907'.

a worni H on the lower end of the steering column which entends up through the carriage body to con-. venient position for the driver. On each end of the shaft F isa pinion I which pinionsengage racksj'on'thc steering rodsJ', T, J 'and J which are pivot-ally conneetcd to the axle casings R at front and rear. On the vright side, as shown, the front steering rod 3" engages the pinion 1- above, and the rear rod J engages the same helowl On the left side this is reversed, the frortrod J 2 engaging the pinion below, and the rear rod J 2 above, so when the shaft F is rotated, the front andrear axles are turned in. opposite directions and are held at any de-i sired angle to steer the vehicle. I

For transmitting the power froni the motor shaft to the drive shaft, a spro ket K is fixed on the shnftk of the change speed and reversegear and is connected to the outside sprocket of the differential L on the drive shaft A by means-jot achain which also passes over idle sprockets M, on each side, 'conn ectc'dand supported by a quadrilateral toggle frameBthe bars of which-are pivotally connected: at the. ends of the'shafts of the sprockets K,' L M and M, respectively. By this con;

struction vibration or variation.of the-:vehiclebody with respect .to the mining geardoes not vary the tensionpf the c hainandthe; pullof the chain sustained bythefraine and not-by the of the vehicle.

The vehicle body '1 maybe supported on elliptical lend springsindicated at N andrestingj on the fork of the reach at each send, directly over the'housin'g at the Iniddle of each axle. -.One en l of. the reach casing D is provided withaswivel P to, allow for distortion or twisting on uneven roads. 1/ as will; be seen, all the -wheelsare drive wheels, and

the direction of travel thereof will be substantially in line with the direction of travel of the vehicle. Consequentl'y slipping or skidding will-be practically-pro vented and the driver have mnch better control "of the vehicle. The foul-drive wheels will give twice as much hold on the road as two' drive wheels and therefore the whee'lsjwill be much less'liable to dig dowrn into snowor sand. Also, by applying power to two axles instead'of to four the s gears is correspondingly reducedjandthe diameter. of; the wheels may be greatly increased without increasing the strain on the axlesnnd gears and with the advantages 'of higher speedand easier riding quality of larger wheels. In consequence of-th double steering axles the vehicle will readily respond to, the steeringwheeL 1 since a slight fof the two'airles in opposite directions enablel he driver tolmake as abru t a turn as I I desired. i

If desired iii vehicles ofhesvyconstruction or "in those designed'to carry heavy loath, such as trucks and drays, the reach D may be secured rigidly tojthe' rear. axle R and pinion: may engage the differential on the a'xlesand their G d V ly 'without the interposition of disk B at this- "'"""2, Tn a running gear lhe romhinatioh wlth sectional rear axle The rear end of the hody could then he supported on two springs. one on each side and resting lirertlyon the axle, and the stecringwe effected by swinging the front, axle alone. In this case the axle.

differentials would both he pieced on the same side of the driving shaft. v

The quadrilateral frame. I. may of course have two of its sides adjustable in length in order to provide a suit-- able chain tension.
