Associated with the frame structure 22 of the velocipede is the main is also provided with first and

second flangeportions

46 and 47, respectively. These flange portions extend gen: erally normal to the

flanges

48 and 49 at the intermediate portion with -the first flange portion located at the first end portion o flthe frame structure and with the second flange located at the second end portion of the frame structure. The upper .edge' portion 41 ofthe second mating section 34' is provided with firstand second

depressed portions

50 and 51, respectively, which are located at thefirst and second end portions,. respe c tively, of the frame structure and which complementarily interfit with the first and

second flange portions

46 and 47 of the first mating section. Each of the mating sections is provided-witha half round bearing member support 54 at both the upper and lower edge portions thereof which is located at the first end portion 36 of the frame structure.

A cylindrical bearing member ,57 resides within the half round bearing member supports 54 of the two mating sections and is fixedly'secured thereto by spot welding, as at 58. The cylindrical bearing member 57 is best seen in Figure 13 and, as shown, includes wall means which define a cylindrical bearing having first and second spaced end portions. Thisbearing member 57 is adapted to house the axle which extends from the main front wheel assembly 24 which, in turn, interconnects with the steering handles '25. This bearing member permits turning of the front wheel assembly.

'Each of the

mating sections

33 and 34 at the intermediate portion thereof has the flanges on the upper :and

. lower edge portions outwardly-enlarged, as at 60 (Figure 9), thereby forming a mounting cradle which is adapted to house and hold a seat supporting bearing structure '62 which receives the shaft which extends from the seat 26 to'hold the same in place and to provide vertical adjustment therefor. The seat supporting bearing structure 62 is shown in detail in Figures 10, 11 and 12,'a nd includes first and second

complementary sections

65 and 66,: respectively. Each of the complementary sections -65 and 66-comprises first and second connecting portions 68-and 69, respectively, which terminate at either end portion in spaced mounting cars 70. A half rounded portion. ,72 is integrally formed with and interconnects the first and second connecting

portions

68 and 69, respectively. The first and second

complementary sections

65 and 66 are secured together by spot welding as indicated at to form the seat supporting bearing structure. Securedto the inner wall of the first complementary section 65 is a plate 74 and through this plate and section is provided a threaded opening 76 which extends generally normal to the extent of the connecting

portions

68 and 69. A screw 78 threadably interfits the opening 76 to securely hold the shaft which extends from the seat 26 through the opening -formed by the hearing estructure r62. Ihis screw 78 may be loosened-andttightenedrastdesiredtto provide the properzverticaliaiijustment to .the seat (26. The seat-supportinglbearing structure.62, shoWn .inIEigures .10 through 12, is platted Q he mounting icradle .formed by the venlargedportions 60 .in the two hollow mating sections ran dlis securely spot welded in place, as at -79, bestseen inQEigure "8. .seen jn'l igures 8 and T9, the first and -.second ,hollow tr'natingsections "3'3 and734 are securely vhldtinplacelby spot welding of the'fianges 44;

45, -48 and 49,, as findicatedigenerallyjby the reference v At the second endvportion-of the frame structure there extends :a -rear wheel assembly connecting structure 83. This connectingstructure 83 'isfformed as .-a laterally extending continuation of the

mating sections

33 and 34, respectively. "This connecting structure includesan annular extending "flange "8.4"which, 'in the "finished velocipede, is connected to the rear Wheel assembly '27 by means. of spot welding;no't shown.

'The method of making the frame structure, "shown in Figures "1, 8 'and'9 fincl'udes'ithe steps of 'selectingfirst and second'metal'blanks. One of thesemet-al blanks'has been shown inFigurefZ andhambeenindicated bythe reference numeral 388. 'The Jnetal1'blanks88 have first and second end portions'89 and90,;respectively,"and anintermediate portion 91-"tl1erebetween. "I"he""blanks 88 are provided with opposed slots "92 on "opposed "edge portions 93. These slots "92 vare "located *at the intermediate portion 91 oftlre blank. Midway/between the slots 92, "the inten mediate portion of *the blank provided -wtih an aperture "94. The *next step in making "the frame structure present invention "isthe "forming of'theblanks of Figure 2 into a half shellconfigu'ration '97, as shown in Figure 3 and Figure 4, with the flange "98 extending substantially eompletely around theedge-portions of the configuration. This operation is accomplished by the use of male 'and'female dies andrnaybe referred to as a forming or drawing operation. It will be noted in Figure 3 that the Width of the flange' 9'8 is substantially the same 'dimension as the length of the slots 92. In-this same forming operation -.each' of the blanks is provided 'with half'round bearing'menibersupports 99 and the nose 'or first end portion-is qprovidedwith-a'rib 100.

The next step *is *thatof trimming thefianges on the halfshell conili'guration'eshown-in'Figures 3 and -4 so that they are ofconsistent idirnension'throughou't their entire length. This trimming operation rernoves that portion tif'thellange '98immediate'ly next to the half round bearingmeniber supports99 to clearly define the same and at the same time forms the first and

second flange portions

46 and 47, respectively, which are the flange portions referred to "hereinabove' in :the discussion .of the finished frame structure. -At the same time that the first and second flange 'portions 46 'and 47 are being formed the flan'ges --'4'4,- 45, 48 and -49 of the finished frame structure -are being"formed. 'This'is'the step-in theoonstruction of the first"liollc-w rnating section 33 of the .:cornpl'eted frame structureand ihe construction of the :secondihollow mating section"34 is' 'identical with the-:exceptionithat instead of the first and second Iflange portions 46 Tend :47 being"formed, 'the=metalwhich makes up these flange portions ou the first rna'ting section 33 is :compl'etely remo'ved IOU the second n-rating section 54. Otherwise the construction of the two is identical so that' the two may 'be-assenibled' to form the completed"framesstrueture of Figures "1, "as and 9. "The next stepinvdlved in making the first hollow mating section '--33 is illustrated in 6 "7 This step includes the bending of the first an'cl "second *flange portions '46 :and 47 through an angle er substantially ninety degrees so that they are substantially normal "to the iflanges *48 and '49. "In'zthis same operation, the rear wheel connecting structure 83 "is provided with the annular extending 'fi'ange"84 and tbe intermediate portion of the mating sections immediately on either side of the slots 92 is provided with the outwardly enlarged portions 60 which form the mounting cradle for the seat supporting bearing structure 62. The construction of the second hollow mating section 34 is identical with that shown in F'rgures 6 and 7 for the first hollow-.mating section 33 withitherexceptiontthat,instead of bending

thefiange portions

46 and 47, the second mating section fad -is providedwith 'tlreifirstsandesecond depressedportionsi50 and 51,.shown inFiguresS, 14 and 15. The operation sbown 'in Figures '6 and 7 and described hereinaboue isicarried out with :the use of male and female dies in much the same manner as the opera tions shown in Figures 3, 4 and 5.

After the first and second

hollow mating sections

33 and 34 have been formed, as described hereinabove, they are,placed 'in rcomplementa'r'y engagement with each other with the seat supporting bearing structure shown in Figures '1'0' through 12 in place; andfithe first 'fiange portion 46 and "the first depressed portion 50 are 'spo'twelded together immediately behind the bearing member supports 54. "This .is done without bearing member 57 in place and therefore one .of the "electrodes "of the spot welding apparatus "may be inserted through 'the opening formed by the "supports '54 "to reach the point 'o'f the weld. The cylindrical bearing member'57 is thenplaced inthe'pos'ition shown in'Figure 8'and-9 and-is'spot-welded in "place-along "with'tlre seat-supporting "bearing structure and thedianges 4'4,-'45,*48and-49, respectively. The sec ond flange and -depressed portions are capable of being spot welded together since the place of weld may be reached through theoperiing formed by ii'a'nge'84. The portion er the support structure formed by the 5 first and second flange portions --provides a :smooth construction which obviates the possibility of injury-to a youngster nsingthe veloeipede.

-A'fter the frame structure" 22, 'shown 'in Figures and '9, has been -'cornpletly assembled, the "components of the -velocipette are assembled, as shown in Figure 1. axle of the front wheel assembly 24 extends throughthe cylindrical bearing member "57 and is secured to the steering handles *25 and the bearing member *for theseat 26 extends through the seat supporting bearing structure 62 and is heldin place and vertically adjusted by means of the screw "78. The annular extending ilange "84 of the rear-wheel -connectingstructure 83 'is'next spot wanes in place to the rear wheel assembly 27*and the'velorcipede is then ready for use.

Although this invention has been-described in its preferred form with a certain degree iof particular ityfiit "is understood that the present disclosureo'f the preferred form "has been'made only by Way of example and that numerous changes inthe details of construction andthe combination and arrangement of parts may be'resorte'd to Without departing from the spirit and the "scope of the invention as hereinafter claimed.
