HUB-BAND.
SPECIFICATION forming'part of Letters Patent No. 486,653, dated November 22, 1892.
Application led July 13, 1892. Serial No. 4:3 9,874. (No model.)
To LZZ whom t may concern,.- from itsinner t-owarditsouterend and formed Re 1t known that I, CHARLES L. VVIEDRICH, at its inner end with the vusual flaring lip a. acitizen of the United States, residing at Bufh is an inwardly-projecting annular lip or falo, in the county of Erie and State of New flange formed at the outer end of the hub- 5 York, have invented new and usefullmproveband, and C is a stiffening or reinforcing ring 55 ments in Hub-Bands, of which the following fitted within the outer portion of the band and is a specification. seated against the inner side of the flange b. This invention relates to an improvement in In producing my improved hub-band a dat wrought or sheet metal hub-bands which are circular blank of sheet metal is first bent into xo stiffened or reinforced at their outer ends. the shape of a shallow cup of larger diameter 6o These hub-bands have heretofore been'reinthan the nished hub-band by means of dies forced by bending the outer end of the band D and E, as shown in Fig. 2, the lower stainwardly upon itself, so as to form a double tionary die E having a shaping-cavity e, into thickness of metal; but this construction is which the fiat blankis pressed by the upper I5 unsatisfactory, because in bending over the movable die or plunger D. The shallow cup 65 outer end of the band the metal is liable to so formedlis next elongated or increased in crack or break. depth and reduced in diameter to the size of The object of my invention is to reinforce the finished hub-band between dies F and G, the outer portion of the hub-band in such a Figs. 3 and 4, the cavity of the die Ghaving zc manner as to obviate cracking of the metal the proper depth and diameter to impart this 7o and so as to produce a smooth and sightly form to. the blank.

Like letters of reference refer to like parts By thus constructing the ring the small end in the several gures. of the cup is slightly expanded in wedging A, Fig. 7, represents the body of the hubthe ring into the same, whereby the ring is 5o band, which is preferably slightly tapered reliably held in place. The lower reduced roo portion oi the pitingerl is made of suiiicient length to extend through the bore `of the reinforeing-ring in driving the same into the cup, and is formed at its lower end with a cutting-edge i', whereby a oircularopeningis eut in the bottom of the cup at about the saine time that the reinforeingring is seated in the same. This opening is of about the same diameter as the bore of the reinforcingring, as shown in Figs. 6 and 7, so as to leave the inwardly-projecting iiange or lip bat the outer end of the hub-band, against which the ring bears and whereby it is confined in the band. While I prefer to out the opening in the bottom of the cup-shaped blank and drive the reinforCing-ringinto the same by a single operation, as before described, it is obvious that the opening could be cut by a separate operation either before or after the ring has been driven into place.
In my improved hub-band the flange or lip at the outer end of the band is simply vbent at a sufficient angle to the body of the band to retain the reinforcing-ring in the same, so that the metal is not liable to crack or break in bending it, as is the case in a band in which the outer end of the band is doubled or turned inwardly against the body. As the reinforein g-rin g forms no integral part of the 3o band, but is separate therefrom, its thickness and consequent strength are not determined by the thickness of the metal of which the band is c0nstruoted,as in the prior construction above referred to; but the ring may be made as heavy and strong as is necessary to properly stiften the band.
I `claim as my inventionl. A sheet-metal hub-band provided at its outer end with a separate reinforcing-ring driven into the band, with its peripheral face bearing against the inner surface of the band, whereby the outer end of the band is stiffened, substantially as set fort-h.
2. A sheet-metal hub-band provided at its outer end with an inwardly-extending flange and a reinforcing-ring arranged Within the band and bearingwith its outer face against the inner side of said iiange and with its peripheral face against the inner surface of the hub-band, substantially as setforth.
3. A sheet-ineta1 hub-band having at its outer end an inwardly-turned flange or lip and a split reinforcing-ring sprung into the band and bearing against said flange, substantially as set forth.
fitness my hand this 7th day of July, 1892.
