DEVICE FOR VPREVENTING smrrnve OF MOTOR-DRIVEN VEHICLES.
and useful Improvements in Devices or Apparatus' for- Preventing Slipping of Motor-Driven Road-Vehides, of which the following is a specification. This invention has reference to a device orapparatus 10. for preventing slipping of motor-driven road vehicles, and has for its object the prevention, or reduction, of .the liability of such slipping, arising from a rapid change of direction of motion of the car, consequent upon the operation of the steering mechanism, or from 1 other causes.
' According to this invention an additionalwheel is. provided, situate preferably, approximately equidistant between and slightly behind the rearward, or driving wheels of the car. This wheel may be held-by .'and revolve in the forked arm of a vertical rod, capable of rotary movement in collars or 'sleeves, formed in, or held by,- a bracket secured, it may conveniently be, to the underside of the car. It is driven from the mo: tor, it may be independently ofthe driving wheels, through a system of spur wheels, chain, and band, or
other suitable gearing and is held in close frictional contact with the road surface by means of a spiral or other spring, or weight, which may beladjusted' to any r'ebuired pressure, or may be operated by a lever or'oth- SO'ferWise', to increase, reduce, or remove, ,the frictional pressure as'required. The additional wheel is coupled up to and is operated by the steering mechanism, so that it will be caused to change, to any required extent, the direction of its motion, simultaneously with and corresponding to, that of the steering wheel, or wheels, of
the car. I l I It willbe obvious that apparatus suitable for coupand also for communicating motion thereto from the 40- niotor, may be variously constructedv without depart ingfrom my invention. One suitable form-is shown in the accompanying drawings, in which i 3'. i
' Figure 1,;is aside elevation, and Fig. 2 a plan; the
apparatus being shown as applied to the chassis. of a car.
Fig. 3,is a rear view, to an enlarged scale, of the'addh .tional wlieel and of a convenient arrangement of supportingand operating mechanism therefor. yFigs. 4 and 5 are a side elevation and plan respectively (also to an enlarged scale) of the additional wheel and. means for communicating power from the motor thereto independently of the driving wheels of the 'car.' Fig. 6 is a view (to an enlarged scale) of the steering actuating mechanism. I
a is the additional wheel, which is shown in the posit Specification of Letters Patent.
Application filed August 17',
tion I have found most efiicient in counteracting side 'Patented oct. 15, 1907.

slip of the rearward or driving wheels of the car. It is supported in the forkedarm b ofthe vertical rods and has motive power communicated to it through the rod d and gear wheels e, which are coupled to the gear box f by therrod g. V
h is a slotted arm connected t9, and extending from one side, of the forked arm b1.
t is a rod one end of which is capable of adjustment in the slot 3 of the arm h;'its other end k is connected through levers Z--l and link m, to the steering quadrant .n. a
Change in the line or direction of travel of the additional wheel a in relation to that of the steering wheel, or
wheels, may be varied according to the position the ondof the rod i is caused to occupy in the slot 9', which posij tion may be altered as desired, either by alever oper ated-by the driver, or from time to time by the adjustmerit of the position on the slot of a screw nut on the" end of the 'rodi 0 is a spring surrounding the vertical rod for maintaining the additional wheel in frictional contact with I the road surface.
I have shown the invention applied to -achassis fitted: I
with the well known Ackermansteering gear, but'it will be obvious that it is capable oi'adapta'tion to any other system of steering. I By the construction of apparatus as described it will be seen that when the steering wheels are rapidly turned, in either direction, from their. line of" travel, any tendency of the rearward wheels to slip in the oppositei direction, will be counteracted, more or less, according to theangle of-the additional wheel and its retroactive power on the road surface, such power being always exerted in a line approximately coincident with the direction of travel ofthe steering wheels' What I claim as oimy invention and desire to secure by Letters Patent is: ling the additional wheel to the steering mechanism 1. Apparatus for preventifig side slipping or skidding ofmotor-driven road vehicles, wherein an additional rearward wheel, driven from a motor, is coupled to and operated by, the steering mechanism, so that it will be caused to change to any required extent, the direction of its motion and gripping power on the road surface, simultaneously with,
and approximately corresponding to the direction of travel 'of the steering wheel, or wheels, of the car.
2-. In combination with a vehicle and itsdriving moto'r and steering. device, of an additional wheel, means for driving the same, a support. for the wheel, and means for connecting said support with the steering device so that said support and wheel will be moved simultaneously with and traveling approximately in the same direction as the steering wheels.v
In witness whereof I have hereunto presence of two witnesses.
