To (LZZ whom it may concern.-

lle it known that l, JOS'ElPi-t Vt. Ilrlnrrnnnonr, a citizen of the United States, and a resident 'of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Follies t'or Wheels, of

- adapted for use in connection with rubben.

which the following description. I

My invention. relates to a peculiarly-shaped telly for vehicle wheels, and is especially is a full, clear, and exact tired carriage-wheels. lit rosy, however, be employed in connection with any device in which a tubular construction, such as shown, is desirtible.

The object of my invention is to provide a strong, durable, and economical constructionv which is both sunple and cheap to make.

'llhis I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is across-section through the simplest form of my invention.

Fig. 2 is a transverse section through the rolled metal blank from which the same is made. Fig. 3 is a transwerse section of a inodilied form of my invention. :llig. d is a transverse section of one form of rolled-metal blank from which the same may be made. Fig. 5 is a transverse section through another form of my invention, showing the blank from which the telly is made in dotted lines.

. 1n the drawings, A represents metal tube forming the telly, which so constructed that in cross-section its walls conform to the shape of an arch, the principles of which it is designed to possess. The walls of this tube comprise a flat portion u and the parallel portions ,7) I), springing from the ends of said flat portion and curved to give the tube its distinctivc arclnshaped structure. Portion It is thicker than portions 7) l, which latter ere preferably thickest at the point where they spring from the ends of portion (rand gradually decrease in thickness as they approach the center or the arch. .l prefer to construct this tube from a skelp or blank ll, substantially as shown; in Fig. 2. This comprises a rolled-n1etal clilinnel-shaped bar, the portion d, connecting the parallel side portions 6%, of

which is thicker and not quite as wide as said. side portions and in the completed tube forms the flat portion a. The edges of the side portions are adapted to be brought together and welded. to form the arch 0., which spans over said flat portion. In Fig. 3 a modified form oi this tube shown. which includes in addition to the tubular part 0, which is constructed sub stantially the same as tube A, Fig. .1, two corresponding longitudinal ilangesg g, projecting from each end of the flat portion 1 thereof in a direction opposite that in which the curved portions 7) 7! project. The tube illustrated in his. 3 is made from either the blank shown in Fig. l; or shown in Fig. 5. The blank l.) shown in. Fig. 4 is the same as the blank H shown in Fig. 2, hereinl'ielore describeiil, except that it has the corresponding parallel lon gitudinal flanges i projecting from the ends of the portion (Z opposite the side portions 6 0., which are adapted to form the flanges 7 g of the finished tube U. (illustrated in l ig. 3.) The blank l (shown in dotted lines in Fig. 5) comprises a rolled -mctal term the body of which consistsol a flat web l(, having corresponding loinritudiual flanges 1 17 Z? projecting; in the same direction tlifllfiltiiliii,11621.1 and pen nllel to the edges 7*" l thereof. The latter form corri'asponding side entensions which when said blank is rolled so as to bring the butt edges of llanges 7r Iii together and said butt edges are welded form the flanges g r of the tube l). (Shown in Fig. 3.) .At equnl distances apart the web K is provided with small holes or circular openings oi suilicient diameter to :wcoiumodate it spoke. oi the flanges l: are suitably recessed on op poeitc sides ol the blank and at poin s in the same truusvr so plane as the holes in the web. The spoke inserted in the hole in the Web, and when the blank is bent to its proper form and joined together the recesses inclose the lower end of suid spol e,retaining the sainein proper position. When follies are niadeiroln tl'ie'blanksuud tubes shown in Figs. 1, 2, 3, and 41., these holes or circular openings are made in the list thicker portion and the tapering side portions are {)l'OIJGIlY recessed. The spoke inserted in the hole in the flat portion and then theside portions are brought together, thus holding the spoke in the same manner as in Fig. 5.

In practice the proportions and dimensions of the tube are preferably the same as shown in the drawings. They can be modified and changed, however, to suit the exigencies ofthe particular use to which it is intended to put them Without departing from the spirit of my invention so long as the arc-shape tubular idea use as fellies for vehicle-wheels.

is preserved. V

My invention can be used for many purposes, but is more particularly adapted for The form shown in Fig. 3 is designed for use with rubber tires, which will be seated between the flanges g g thereof. The form shown in Fig. 1 can be used as a felly either with or without rubber tires.

-. What I claim as new is 1. A felly for wheelseomprising an endless tube of the same transverse contour from end to end, the Walls of which consist of a flat v gradually reduced in thickness toward theirpoint of contact with each other.

3. A felly for wheels comprising an endless tube of the same transverse contour from end to end, the walls of which consist of a flat thicker portion and curved portions springing from the ends of the flat portion to form an arch over the same, said curved portions being gradually reduced in thickness toward their point of contact with each other.

4. A felly for wheels comprising an endless tube of the same transverse contour from end to end, the walls of which consist of a flat thicker portion and curved portions-springing from the ends of the flat portion to form anarch over the same, and comprising longitudinal flanges projecting from the ends of said flat portion in a direction opposite to said curved portions.

. 5. A folly for wheels comprising an endless tube of the-same transverse contour from end to end, the walls of which consist of a fiat portion and curved portions springing from the ends of the flat portion to form an arch over the same, said curved portions being gradually reduced in thickness toward their point of contact with each other, and longi tudinal flanges projecting from the ends of said flat portion in a direction opposite to said curved portions.

6. A telly for wheels comprising an endless tube of the same transverse contour from end to.end, the walls of which consist of a flat thicker portion and curved portions springing from the ends of the flat portion to form an arch over-the same, said curved portions being gradually reduced in thickness toward their point of contact with each other, and longitudinal flanges projecting from the ends of said fiat portion in adirection opposite to said curved portions.
