RADIUS-ROD. 7

Specification of Letters Patent.

r Patented Dec. 9,1919.

Application filed May l3, 1919. Serial No. 296,766.

To all whom it may concern:

Be it known that I, JOHN D.'BRIDGERS, a citizen of the United States, and a resident of Florence, in'the county of Florence and State of South Carolina, have invented certain new and useful Improvements in Radius-Rods, ofwhich the following is a specification.

This invention is an improved radius rod for automobiles.

One of the principal objects of the invention is to provide a radius rod, so made that the arms of the rod areinter'changeable' so that a single spare arm carried in the car may be quickly put on in place of either arm of the rod which might become bent .or broken when out on the road.

Another. object is to provide a separable anchor member for connecting the inner ends of the rod arms to the engine casing, which anchor member placed by a spare one if damaged or broken.

A further object of the invention is to provide an improved three-piece sectional radius rod which will be exceedingly simple, durable, eflicient in operation and inexpensive to manufacture and maintain.

With these and other objects in view,

which will become apparentas the description proceeds, the invention resides in the construction, combination of. parts hereinafter and claimed, and illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the several figures ofwhich:

Figure 1 represents a plan view of a radius rod. constructed according to my invention, the arms being broken away.

Fig. 2 represents an edge elevational view thereof. 7

Fig. 3 represents a chor member.

Fig. 4. represents a plan view of the inner end of one of the arms. looking at it from the inner side thereof.

Fig. 5 represents an edge view of the anchor member.

Fig. 6 represents an edge view of the inner end of the arm.

Fig. 7 represents a fragmentary edge view of the rod, partially in section, and

Fig. 8 represents a view in perspective of the wire used as a nut lock.

The invention while particularly designed for use in connection with Ford automay be readily re and arrangement more fully described plan view of the "anin the recesses 15 mobiles,

vehicles of other and various makes.

Referring. more particularly to the draw ing, the rod includes an-anchor member '5 and two arms 6. The arms at their ,for-' ward ends are provided with the ,boltsfor fitting through the front axle in the usual manner. The anchor serves to connect the rear ends of the arms together and to the:

on one side of the plate are perpendicular to the axis of one of the rods, while the ribs 011 the opposite face are perpendicular to the aXisof the other rib.

The rods are interchan eable, and are constructed exactly alike. ach rod has its inner end provided with an offset circular flattened seat 11: having spaced parallel grooves 12 arranged perpendicularly to the axis of the arm and into which the ribs fit when the seat is placed against the plate 8 in connecting the arms to the anchor member. .lVhen the radius rod is assembled the arms 6 will be in coplanar relation, the inner offset ends of the arms fitting against opposite sides of the anchor plate.

The flattened ends of the arms are each provided with a central opening 13 alining with the 0pening9 in the rod is assembled. The opening in each rod is counter sunk as at 14 at its outer end, and is provided at diametrically opposed points with recesses 15.

In order to secure the members of the rod together a. bolt 16 having a conical head 17 provided with wings 18 is passed through the alined openings, the wings 18 engaging of one of the arms. A conical nut 19, having a castellated head, is then screwed onto the end of the bolt, the nut being held in place against rotation by means of the nut lock 20.

The latter is placed upon the bolt before the nut is turned thereon, and it includes a split ring 21 which encircles the bolt at the bottom of the counter sunk portion of the opening in the arm into which the nut is to be turned. The split ring terminates at the anchor plate when- A; rs

maybe adaptedfor use with motor,

disposedso thatthe ribs one end in an upwardly extending Wire which rests in one of the recesses so as to be out of the Way of the nut when the latter is turned upon the end of the bolt. The nut having been screwed in place for tightening the parts together, the end of the Wire ex tension is bent down as at 22, across the head of the nut to engage in the notches therein for preventing reverse rotation of the nut. Thus the nut will be locked in place against displacement. The lock wire is of relatively small diameter, so that it Will take up only a slight amount of room.

The wire is, however, of sufiicient strength to retain the nut against accidental displacement.

When the parts arev thus assembled, the interlocking ribs and grooves, will hold the arms and anchor member against displacement relatively to each other. Thrust on the arms 6 of the rod, will be transmitted to the anchor member partially through the interlocking ribs, but primarily through the arcuate shoulders 23 formed at the junction of the shank and plate of the anchor member. Thus the bolt Will be relieved of thrusts, and there Will be no tendency to shear it. The construction is such that no lost motion between the various members of the rod occurs, so that a rigid and strong construction is provided.

By the use of the rod 1 provide, a spare arm and a spare anchor member may be carried in the car, and should either of the arms become broken or damaged, or the anchor member be injured, the part may be replaced simply by removing the damaged member and substituting the new one for it, and this may be done easily and quickly and Without the use of any special tools.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement of parts, as do not depart from the spirit of the'invention and the scope of the appended claims.

I claim 1. A radius rod comprising an anchor member having one end flattened to provide a plate, shoulders formed at the junction of the plate With'the body of the anchor member, a pair of arms arranged in coplanar relation and having their inner ends ofi' set and bearing against the opposite faces of the plate and engaging said shoulders, interlocking ribs and grooves between the arms and the plate, a bolt passed through alining openings in the arms and plate, a nut screwed upon said bolt for retaining the parts in assembled position, and means for preventing accidental displacement of the nut relatively to the bolt.

2. A radius rod including an anchor member having a plate formed thereon, arms having their inner ends oiiset in opposite directions and engaging against opposite sides of the plate, interlocking ribs and grooves between the arms and plate, and means detachably connecting the arms and plate together.

3. A radius rod including an anchor member, arms having offset ends engaging against opposite sides of the anchor member, interlocking means between the arms and anchor member preventing angular displacement of the arms and anchor member relatively to each other, shoulders formed in the anchor member for taking up the thrusts from the arms and means detachably connecting the arms and anchor member together.

a. A radius rod including an anchor member having a plate portion, arms having their ends engaging against opposite sides of said plate portion, interengaging ribs on said arms and plate portion, and a bolt passing through said arms and said plate portion.

,5. A radius rod consisting of an anchor member, a pair of arms, a single securing member passing through said anchor member and said arms and detachably connecting them together, and means including the securing member preventing angular displacement of the anchor member and arms relatively to each other.

6. A radius rod including an anchor member having a plate portion, arms having their ends disposed against opposite sides of said plate portion, interengaging locking means on said arm and plate portion, and a single bolt passing through said arms and plate portion.
