SPECIFICATION forming part of Letters Patent No. 325,692, dated September 8, 1885.

Application filed August 4, 1884.

To @ZZ whom t may concern 3e it `known that I, Antrim S. PARKER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and yState of Ohio, have invented certain new and useful Improvements in Hub-Bands, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specitlcation.

My invention relates to an improvement in hubbands for vehicles. It has'for its object the production of hub-bands of wrought metal instead of cast. Ordinary cast hnbhands are brittle and liable to break when being forced on the hub. In order to make a cast band sufiieiently flexible, it 'must-be annealed by a process requiring considerable time and ex pense. A cast band is also imperfect in shape and ijnish, and must be carefully turned on a lathe to make its form perfect, and to give it a smooth surface for either polishing or plan ing. All these difficulties and objections are overcome by Vmaking the band of Wrought metal of the desired thickness. It is then dnctile, and `.vill stretch and not break. The surface is smooth and finished, and readily polished or plated, and the band is not only much superior, but can be made with a saving of time and cost. I make these wrought hub-bands from previously prepared seamless tubing of the proper size by subjecting itto pressure under propcrly-construoted dies.

My invention also consists in a further improvement in wrought hub-bands provided with an inner circular iiange for attaching to the band an ornamental lining of thin sheet metal.

In the accompanying drawings, Figure lis a sectional side elevation of the die and mandrel or plunger, and a section of seamless Wrought tubing iu process of manufacture into a hubband. Fig. 2 is a similar section of a die for making the hubbaud of a flat sheet of metal. Figs. 3 and et represent the band complete. Fig. 5 showsasection of the sheet metal drawn into a tube before it has been subjected to the dies. Fig. 6 is a dat sheet of metal cut into form for putting in the die. Fig. T is a side elevation -in section of (No model.)

'ference or diameter a little smaller than the upper, so that theA hub-band may be driven on the hub, though, if desired, it may have the same diameter throughout. n

B is a mandrel or plunger of the same shape as the die A, and as much smaller as the thickness of the band to be produced. C is a sheet of Wrought metal. E is ashoulder on the plunger, which fits into the space E in the die when the two are brought together. The die A may be made open or closed at the bottom. The upper edge of the die is made to flare outwardly, as shown at D, Fig. 2, and the mandrel B is provided with a corresponding space or recess, D. As the mandrel B is' forced down into the die the sheet of metal O is carried before it, and is sufficiently ductile to take the shape of the die. There is thus formed a thimble, of which the smaller end is closed or solid. The upper edges are then trimmed, leaving theiiaring lip D", Fig. 3, and the bottom is cut oit or out, leaving the end open, as shown at F, Fig. 3.

The die may be provided with a knife-edge so arranged around the bottoni that the plunger, after completing the form, will press the metal against this edge, so as to cutout the top ofthe thimble, thus forming and cutting the band at one operation. The hub-band is then complete, and is ready for polishing or plating, and need not be turned or shaped or annealed.

Fig. l represents a similar die for making hub-bands of seamless wrought tubing. section of tubing G is inserted in the die A, and as the die tapers slightly toward the bottom the section of tubing G will only go part of the Way down Without pressure, but Will readily receive the bottom or smaller end of the plunger B. As the plunger is forced down, the section of tubing is carried with it by the The IOO

is to be made.

shoulder H, which also forms a lip or fiare around the upper edge, as shown at D, Figs. 3 and 4; or .the tubing G may be small enough to extend to the bottom of the die, when the plunger Will simply enlarge the upper portion and turn over the iiaring lip D.

It is sometimes important to provide a hubband with an interior circular ilange, as that shown at I), Fig. 8, for attaching a thin ornamental lining. These flanges have heretofore been either cast or'soldered in the band, and the thin metal lining soldered to the flange, or spun up into the band around the flange. To avoid the necessity of soldering into the band such a ring or flange, and to make it an integral part of the hub-band, I subject the band, after heating it, if necessary, to pressure in dies so shaped as to upset the metal of the band itself to form such a flange. For forming this circular flange within the band a somewhat different die is used, and this is preferably formed after the hub-band has been made, though it may be done at the same time.

In Fig. 7, A is a die similar to the one shown in Figs. l and 2, except that aspace, K, Within the die is left around the top to receive the shoulder H of the mandrel. In thelower part ofthe die is placed a stationary former, L, as much smaller than the female die as the thickness of the hub-band M. The upper edge of the die or former L is slightly beveled, as shown in the figure. rlhe plunger N is made shorter than the die, the length of N and L being together equal to the depth of the die from the space K downward, or to the/entire length of the plunger in Figs. 1 and 2. The respective length of N and L is regulated by the point in the hub-band at which the flange The lower edge of the plunger N, like the upper edge of L, is beveled to correspond to the size and shape of t-he ange desired. The band M is placed within the die,

the space around its bottom.

N is forced down, the shoulder H strikes the hub-band and carries it down upon itself, the effect being that the band is first thickened until it fills the space between the former L and the smaller part of the plunger N and the walls of the die, and finally a portion of the metal of the band is upset, filling the space made by the beveled edges of the former and plunger, and producing a circular iiange, P, Fig. S, corresponding in size, shape, and position with said space. rlhe outside of' the band remains straightandsmooth. This flange, being of the same metal as the band, is, of course,.ductile, and Will not crack or break when the band is stretched, but serves to strengthen it, as well as to form a bearing for fastening the thin ornamental lining, which may be spun up into the band and around the flange in the usual way.

While I have described the methods which I consider best for the manufacture of Wrought or sheet metal hub-bands, I do not purpose to limit myself to these alone, for instead ofform ing the bands in dies it is evident that they might be spun into the required shape.

The process herein described for for-ming wrought-metal hub-bands Will form the subject of a separate application which I am now preparing; but, so far as the present application is concerned, I do limit myself to Wroughtmetal bands made from previously-prepared -seamless tubing.

Having thus fully described my invention, Ijclaim- 1. Awrought-rnetalhub-band made-of pre- ABIJAH S. PARKER.
