WHEEL AND WHEEL-RIM.
SPECIFICATION forming part of Letters Patent No. 743,098, dated November 3, 1903.
Application filed October 27, 1899. Serial No. 734,919. (No model.)
the accompanying drawings,-which form a part thereof.
My invention relates to the construction of wheels and wheel-rims, especially rims of sheet metal, having particularly in view the formation of rims for pulley-wheels, my prime object being to provide a wheel-rim built up of segments which will'be at once strong,
true, and of easy and cheap construction.
The essential feature of my invention in the construction of the rim consists inv forming a rim of sheet metal folded together intermediate of its edges to form an inwardlyextending two-ply flange and folded out wardly from the top edges of the twoply flange to form the face of the wheel. The edges of the folded plate are also preferably folded inward to form strengthening ribs or flanges, and the plate havingthe T shaped cross-section described is curved in the plane of its central flange to the desired curvature of the wheel-face. The central flange of the wheel-rim section constructed as above noted serves for the attachment of the spokes of the wheel-center and also serves to stiffen and make permanent the curvature of the face of the rim, the edge flanges also serving the purpose of stiffening and making permanent the curvature.
While my new rim can be used with hub and spoke constructions of Various kinds, I have especially designed for use with the T- shaped rim-sections a cast-iron wheel-center the spokes of which are bifurcated at the ends to permit the entrance between its separated end lugs of the inwardly-extending flange of the rim, which is secured to the spokes by rivets passing through the lugs and flange.
Reference being now had to the drawings, in which my invention is illustrated, Figure 1 is a sectional view of a split pulley having my improved rim and cast-iron center, thesection being taken as on the line 1 1 of Fig.
2; Fig. 2 is an edge view of the split pulley withthe edge cut away on the line 2 2 of Fig. 1. Fig. 3 is an enlarged View of the under side of the joint or union formed between two abutted rim-sections. Fig. c is an edge view of the joint shown on the same scale as Fig. 3. Fig. 5 is an edge view taken on the section-line 5 5 of Fig. 3. Fig. 6 is a perspective view showing the folding of the end of the plate forming. the joint as represented in Figs. 3, 4, and 5. Fig. 7 is a perspective view showing a modified manner of folding the plate at its end. Fig. 8 is a view of the inside of the joint formed by two abutted rim-sections, the joint here being of a modified and different character. Fig. 9 is an edge view of the modified joint shown as on the section-line 9 9 of Fig. 8, and Fig. 10 is a view illustrating a convenient way of forming the joint when the rim-sections are used in making up the face of a solid pulley.
A A indicate the hub-sections of the split pulley, said hub-sections being formed with outwardly-extending perforated lugs A and with radial spokes, (indicated at A A &c.)
A indicates enlargements at the end of the spokes, formed with central slots, as indicated at a to receive the central flange of the rim.
' B B indicate bolts, by means of which the hub-sections are secured together.
0 C indicate rivets, by'which the lugs of the enlarged spoke ends A separated by the slots a, are firmly secured to the web of the rim.
D D indicate rim-sections constructed in accordance with my invention. They are formed of sheet-metal strips folded together intermediate of their edges, so as to form inwardlyextending circumferential two-ply folds, (indicated at D D.)
D D are outward folds of the metal extending from the top edges of the flange-folds 1 D and forming the face of the pulley or wheel.
D D indicate inwardly-folded edges of the plates, forming inwardly-extending flanges, as shown. As clearly shown in Figs. 1, 2, and
ICC
/tlie plane of the flange D D and to the curvature of the desired wheel-rim, the ends of the rim-sections being abutted together, and it is preferable that the abutted edges should be firmly locked in place, as it will be understood that the pulley is more likely to become distorted at the joint than at other points. In Figs. 3, 4, 5, and 6 I have illustrated a convenient and satisfactory way of forming thejoint at the abutted ends of the rim-sections, the ends of the rim being bent inward at a right angle to the face of the rim, forming flanges, as
indicated at D D", which of course are practically in planes radial to the center of the pulley.
To make this end flange, it is of course necessary that the central rim-flange D should be out. Preferably I out it away at an angle of ninety degrees, so that the bevel edges, as indicated at D and (1 will abut together, (see Fig.
6,) the portion of the central web attached to the folds D D beingindicated at d. The ends of the rim-sections being bent to the positions shown in Fig. 6 are then firmly secured together by angle-irons, as indicated at E E E the portion E lying against the end folds D, the portions E lying against the central flanges made up of the portions D and d, and
the portions E abutting against the edge folds D Rivets are conveniently employed to secure the portions E and E of the angle-iron to the flanges of the rim, and bolts are employed, as best shown in Fig. 3, to secure the plates E and flanges D 'together and to secure the abutted flanges in position. I have also braced the inwardly-turned folds D in position by separating the web portions 01 from the web portions D by means of a straight out, as indicated at D d and then lapping the portion (1 on the portion D, as indicated in Fig. 7, employing rivets to secure the lapped portions together.
In Figs. 8 and 9 I have shown an abutted joint in which the rimsections are not turned in at the ends, but are abutted against each other and secured together by angle-irons E E the portions E of the irons being riveted to the rim and the portions E riveted or bolted together. The abutted joint between the rim portions is indicated at D D".
- Where the pulley is a solid and not a split one the joint may be made as shown in Fig. 10, in which I have partly broken away one of the lugs of the head A on one side of the groove a formed in it. In this construction the two rim-sections D D form an abutted joint, as in Figs. '8 and 9, the joint being braced and the parts alined by bringing one of the spokes of the pulley into alinement with it and riveting the ends of both sections of the rim to the same spoke of the pulley.
I am aware that sheet-metal wheel-rims have heretofore been made up of separate flanged segments, two or more such segments being abutted together to form the full breadth of the rim and intermediate circumferential two-ply flanges; but in all such constructions the plies of the intermediate flanges are merely in contact and only held together by separate fastening device. My
. rim is distinguished from such prior constructions by the union of the plies of the flanges throughout their inner edge, whereby the structural strength of the flange is greatly increased and the strength of the rim as a whole and also the correct alinement of the parts on each side of the flange is greatly promoted.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is r 1. A wheel-rim section consisting of a plate of sheet metal folded together at a point intermediate of its edges to form an inwardlyextending two-ply flange suitable for attachment to the spokes of the wheel and folded outward from the top edges of the flange-folds to form the face of the wheel, said folded section being curved circum ferentially in a plane parallel to the flange.
2. A wheel-rim section consisting of a plate of sheet metal folded together at a point intermediate of its edges to form an inwardlyextending two-ply flange suitable for attachment to the spokes of the-wheel, said plate being folded outward from the top edges of the flange-folds to form the face of the wheel and again folded inward at its edges to form strengthening-ribs, said folded section being curved circumferentially in a plane parallel to the flange.
3. A wheel-rim formed of plates of sheet metal folded together intermediate of their edges to form inwardly-extending two-ply flanges suitable for attachment to the spokes of the wheel and folded outwardly from the top edges of said flanges to form the face of the wheel, the ends of said plates being bent in at right angles to form abutting faces and secured together in forming the complete rim.
4. Acast-metal wheel-center having formed integral with it, radial spokes slotted at their ends, in combination with a rim of T-shaped section formed by folding sheet metal together to form a two-ply web and outwardly from the top of the web-flange to form the face of the wheel, said rim-section having its two-ply web fitted into slots of the spoke ends and secured thereto.
FERDINAND PHILIPS.
