In a ,copending application of Eber J Hubbard, Serial N 0." 406,772, filed November 3rd,; 1929, there is disclosed a reel whose laminated end discsor heads are provided withjai sheet metal reinforcing rim or tire intimately clinched thereto, and with sheet 15- metal bushings clamping the lamination together at-theaxes of the heads. An iinportant object of our invention is to provide simple and efiicient apparatus for quickly and economically applying the rim or tire 2o with securing clamping and clinching engagement to the periphery of the head and during the same operation applying a sheet metal bushing in an axial bearing passage 'thi 'oughthe head/co rigidly and securingly clamp the head. lamin'ations together at the head axis. ,The' various features ofour invention are embodied in the'structure disclosed on the accompanyingdrawings, in which Figure 1 is side elevation showing the relatively movable parts of a press and the ,re'enforc'enient applying apparatus mounted thereon; 7

Figure 4 is a similar sectional view showing the parts after the pressure and applyingoperation Figure ,5 is an enlarged cross-sectional view of the reel head and reinforcing rim in embryo form; and

Fig. 6' is a similar sectional view showing the rim fully applied.

On the drawings, 10 represents the base or b'ed and llthe reciprocal head of a press, the bedand head having opposed cylindrical depressions or pockets 1 2 and 13 respectively.

placed in the apparatus ready for theapply Surrmin'dingthe bed pockets 12 is anannular boss 14 forming a seat for the lower annular die 15, the die abutting against the shoulder 16 on the boss and havin its inner face flush with the inner face of the pocket 12. 'The movable head of thepress has the annular recess 17 surrounding. the pocket 13 in which recess is seated the annular upper die 18 with its inner face flush with the cylindrical side of the pocket 13.

Reciprocal within the die 15 a circular supporting discor plate 19 whose diameter is substantially equal to the inner diameter of the die,and interposed between this plate and the bottom of the pocket 12 are a number of compression springs 20 which tend to hold the plate in its outer position indicated in Figure 3. Stop studs 21 extend down,

wardly from the plate and through Ushaped brackets 22 secured to the bottom of the pocket, the heads 23 on the studs, by their engagement with the bracket ends, limiting the outward movement of the plate.

The "late 19 has the axial cylindrical passage- 2 for receiving the cylindrical die stud 25 piojectihg upwardly from the press bed 10' in the pocket 1.2, this die stud having the I outer reduced end or neck 26 for a purpose to be hereinafter more fully explained.

Reciprocal within the upper die 18 is a circulardisc or plate 27 whose diameter is substantially the same as the inner diameter t v of the die and between which and the bottom Figure 2 is a plan view of-the'apparsttus;

of the pocket 13 are interposed a number of compression'springs 28 which tend to hold the plate in its outer position as shown in Figure-3. The studs 29 extending from the plate through the brzicketsBO secured to the press head 11 have the heads 31 for engaging against theouter ends of the brackets to limit the outward movement of the plate 27.

The reel head, for the assembly and reenforceine'nt of which our improved ap paratus has been designed, comprises two circular discs 32 and 83 which may be of non-metallic material such as wood. The reinforcing rim or tire T is primarily of the cross-section shown in Figure 5. This initialiorm is obtained by rolling a length of plain band of sheet metal to circular radially inwardly from the groove 35, and the outer edge section E of each disc between the groove and the recess is rounded to be of substantially semi-cylindrical crosssection. Around these semi-cylindrical edge sections the sides A of the embryo tire structure are to be intimately deflected with their ends within the recesses 36 as indicated in Figure 6, these sections being then securely clamped by the clinching thereto of the tire structure sides.

The annular dies and 18 have the die or forming .grooves '37 corresponding in shape with the peripheral edges of the discs around which the sides A of the tire are to be clamped and clinched. Referring to Figure 3,the press head 11 is normally raised away from the bed 10 and the supportingplates 19 and 27 are'in their outer p0sitions.- When a reel head is to be assembled and reinforced, two discs are applied from opposite sides into an embryotire structure to receive the ridge 35, and the assembled discs with the tire structure thereon are then laid on top of the lower plate 19. e

In order to accurately align the discs and the embryo tire with the annular dies and to hold the tire against distortion while the the sides are being deflected sand clinched around the disc peripheries, an aligning and clamping frame F is provided. This frame is annular and concentric with the annular dies and is preferably composed of the two semi-circular sections 38 and 39 hinged together by a pin 40 at one end and having their other ends detachably locked together by a suitable latch asfor example a hook 41 pivoted to one of the members and a pin 42 on the other member, the hook being readily operableby its handle or grip 43. The member 38 of the aligning and'clamping frame is; secured against radial displacement} by means of pins 44 extending upwardly from the pressbedlO and these pins also serve to center and align the press head 11 relative to the bed when the head is forced down.

'The frame F is, however, free for axial the movement, such movement being guided by pins 44. v

Each of the frame members 38 and 39 has a number of pockets 44 provided with re movable covers 45. A foot 46 extends downwardlythrough an opening 47 in the base Each disc has also an annular recess 36 in its outer side a short d1stance' of each pocket 44 and within the-pocket has an abutment head 48 for a compression spring 49 which abuts at its upper end against the cover 45. The feet 46 rest on the press bed 10 and normally the springs are extended to hold the frame in vertical alignment with the reel head forming parts placed on the'plate 19, the frame members having the semicircular dies or engaging inserts- 50 and 51 of such cross-section that at their inner ends they will fit into the annular belt groove 34 formed in the outer side of theembryo tire by the ridge 35 therein. Before the head discs with the embryo tire thereon are applied to the plate f 19, the frame member 39 is swung outwardly to make way therefor and then the member 39 is swung back and interlocked with the member 38 by the hook 41, a handle 43 forming a convenient means for swinging the member 39. The die andabutment inserts 50 and 51 willthen engage in thetire groove and will hold the discs and tire in accurate alignment 011 the press readyzfor the clamping and clinching operation. The press is now started and as the press head 11 travels downwardly itsplate 27 will first engage with the upperreel head disc where-' upon the springs 20 and28v are put under compression so that the reel head'discs are securely but resiliently clampedtogether between the plates 19 and 27. During such.

clamping'the plates move downwardly with the clamped discs and the frame F will move downwardly therewith, and pins 44 on which the frame member 38 is slidable, serving to accurately guide the frame F in its downwardly movement, and such move ment is resisted by the compression of the springs 49. Eventually, the annular dies 15 and 18 reach the projecting sides A of the embryo tire structure and these sides are curled, clamped and clinched around the semi-cylindrical peripheral sections of the reel head discs, the frame F rigidly holding the central portion of the tire during such deflection and clamping of the side sections of the tire and during such opera tion the spring'pressed plates 19 and 27 hold the reel head discs securely against each other. i

The reel heads usually have axial openings for. receiving a supporting shaft for the reel during winding or unwinding thereof. To reinforcev such bearing openings sheet metal bushings are preferably provided and our improved apparatus may be readily adapted to apply such bushings simultaneously with the clinching of the tire structure to the headdiscs.

the press a sheet metal bushing 52 is inserted in the registering openingsv 53 provided therefor in the discs. Such bushings may readily be formed by rolling from a sheet Either be fore or after the head discs are placed in i is 'p ovi metal blank sirdprereratty the edges of the bushi' g have serrations or teeth 543'. For clamping these bushings to the heart discs the die stud 25, already reierr'e'd to, ed on' the press head A corn p; in die'stud 5o is' providedon the press hear sashes the reduced end or neck 56 like the neck- 26 of the stud 25. The upper plate 27 has the opening 57 for,receiving V thestu'd and as the press head is moved downwardly the plate openings 24% and 57 receive the studs and'55 respectively and: the stud necks enter the opposite ends of the bushing 52, Then as the serrate'dends of the bushings areengag'ed by the shoulders 58and 59 of the respective die studs, they "are deflected radially outwardly-and then downwardly against the outer face of the discs32 with the teeth or serrations impressedinto the discs so that the bushing will be securely locked against ro tation in thediscs: When the press head 11, is now withdrawn, the frame member- 39 is swung open and the finished and reinfo'rcedreel head is removed'from the press;

7 The apparatus pzirtsare rest red to their normal -position by their. springs ready for receiving another charge of reel headform- ,ingparts.

We thus produce a simple and efficient apparatus by insansbf which a reinforcing sheet metal tire and bearing bushing may bequickly, accurately and economically ap plied to non-metallic discs, to form a reinforced reel head.
