Y. ROBERT P. SIIHTONS,i OF CLEVELAND,OHIO.

SHEET-METAL RADIUS BOD.

Application led March 2.0, 1923. Seria1No.-626,249.

State of Ohio, have invented a certain new' and useful 1 Improvement in Sheet-Metal Radius Rods, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a sheet metal radius rod.

Heretofore'this type of radius rodv has been made from tubes in the ends of which has been welded or otherwiseA secured a forging by means of which the rod has been secured to the engineand axle or other parts of the' automobile.

`One-Well known construction is to employ a two-piece socket connected to the crank case of-theengine and fitting into this twopiece socket is the spherical end of a forged coupling, -said coupling having separated member-sto which the tubular radius rods are welded or otherwise secured andthe opposite ends of these radius rods have been providedwithv forgings either in the form of albolt adapted toproj ect through the axle or having an eye for fastening to the axle by vmeans of a bolt. l

Radius rods constructed in this manner are lmore expensive to manufacture and do not possess the same amount of strength as the radius rod herein shownv and described`.`

Broadly speaking, the invention consists in providing a sheet metal blank and shaping `the same to provide at one end one half ofthe connecting portion which fits into the socketV and at `|thev other end a reinforcing portion shaped for connection to the axle.

The invention consists also in the novel form of the complementary end portions and also the novel form ofthe reinforced end. The invention consists also in certain details hereinafter fully described and set forth in the appended claims. y

In the drawings forming a part of this specification Fig. 1 is a view showing one of theradius rods; Fig. 2 is ak view showing the other radius rod; Fig.` 3 is a view showing the radius rods connected together in their proper positions for connection to the motorvehicle.

Fig. 4 is a .view showing the rear ends arranged together ready for insertion into a spherical socket.

VFig. 5 a View of the blank. i i

Figs. 6, 7, 8, 9,' 10, 11, '11, 12, 13 andli show successive steps rin the shapingl of v.the i rod.

Fig. 15 is and i Figs. 16, 17, 18 and 19 show a modified form of end and method of. making the same.

a side yview of the complete rod;

rods and at the rear end ,thereof there is a closed neck portion 11 and at the? end ofthis neck portion 11 is the hollow hemispherical head 12 having a lip `13 -disposed along the edge, and preferably set backfromsaid edge as shown. At the opposite end of` the, tubulary body portion 10 there isan integral apertured enlargement 14C and this enlarge-l ment; isvvo-ffset from the longitudinal kaxis ofthe vtubular rod'portionl() as most clearly shown. 15 indicates the tubular body portion of lthe radius rod whichy is likewise formed withthe closed neck portion 11 and thev complementary hollow hemispherical portion 12 having the offset integral llip 13 and these hemispherical lhead portions: are

so` constructed that when placed together they .will provide aco-mplete sphere which fitsintothe two-part socket 16 arranged upon thefbottom of l.the engine crank case and the offset lip `portions lfengage the `interiorfaces ofnthe opposed heady portions and thereby hold said complementary-head portions from relative movement-...one with the other. j 'i inasmuch as Athese complementary head portions areA ittedinto a clamping-socket the interlocking lip portions may in some instances be dispensed with if so desired and if' some locking means must be: provided in order to prevent .anypossiblemovement I may interpose a ball shown in dotted lines at 17 which lits into the complementary hemispherical `head portions and thisball Referring to the drawings 10`indicates thetubular body/portion of one ofthe radius I be solid or hollow as preferred. The

enlargements 14 in order to bring saidy en-y largements in the same plane beneath the axle as most clearly shown.

A radius rod embodying the features just described and composed entirely kof sheet metal is stronger than a radius rod composed of ay tubular body portion and forged ends. Furthermore, a radius rod composed entirely of sheet metal can be manufactured in less time than the old type and for less money.

In casefitl is preferred to -have the forward ends of the rods attached to the axle by projecting the ends thereof through apertures inthe axlevit can be accomplished by forming the forward ends o-f the blank so that they can be folded around a bolt or rod which can be projected through the opening in the axle and secured by means of a nut, the folded blank shown at 22 securely positioning the shouldered bolt or rod which in turn also serves as a reinforcement for the end of the rod.

In constructing radius rods from sheet metal in accordance with my invention, I

'first punch the blank as shown at 30 having the head portion 31 at one-end and the enlargement 32 at the oppositeend. During the first operationthe edges of the' bodyv portion are bent up slightly as shown at 33 and in the third operation the edges o-f the neck are bent up as shown at34 and the opposite end is `cupped as shown at 35. During the next operation the hemispherical form of the head is embodied as shown at 36, the'lip beingin the line with the edge of the head section and the edges of the neck portion drawn somewhat closer together as indicated atk 38 and the cup-like portion at the opposite end is turned slightly inward at one end as most clearly shown `at 39.

When 'the forward end of the vradius rod is to be offset a depression 40 is producedv adjacent the cup-like portion which has been formed.' 1 p Y, After the blank has passed throughthe operative stages just described a washer 41 is inserted in the cup-like portion and then the edges of the rbody portion are brought to gether and likewise the edges of the neck portionthe neck portion being folded together and offset so as to provide a substantially solid neck portion between the end of the.r tubular rod and the hollow hemi- .like portion (Fig. 14) and in this manner the washer is securely fastened in the folded over sheet metal end providing a substantially solid endand then by means of suitable shaping dies the end thus formed is given its proper relative position with end being tially circular head and as before stated inasmueh as the radius rodsfare right and left and formed with complementary head portions which when slipped togetherl provide a spherical head which lits into a socket it is necessary that the. forward end of one of the rods be offset in order that the said forward ends can be arranged in the same horizontal plane in case theforwardends ofv the radius rods are to be secured to the underside of the front axle. W'hen .the forward end of the radius rod is to be passed through the front axle the forwardrend of the blank is shapedslightly different as indicated at 22 and the shouldered bolt 24:v is placed in said end after the same has been stamped to a semi-circular cross sectional form and then the end is .completely folded over the bolt, securely fastening the same, and the end is threaded providing the threaded end 230i' the reinforced'rod. The. shouldered boltprevents the withdrawallof the same, and the enlarged endprovides a point against which the offset ortion of blank can be folded (ligj).v 7hen the neck portion is completely closed the lipis also offset inwardly as shown, this offsetting being necessary in order toA permit the said lips tol engagey the interior surface of the'- opposite headl portion wheat-heg two hfead portions are placed together to provide a complete spherical head ywhich is tovbe fitted los neck portion, the hemispherical head por; y

tions being provided with means to prevent displacement.

Having thus described' my invention, what I claimis: w., i f;

1. A sheet metaliradius rod havingwa hemispherical` enlargement at oneend, and an apertured yenlargement at the opposite end. -v
