METAL WHEEL.

Specification of Letters Patent.

Application filed July 5, 1912.

Serial No. 707,739.

7 T 0 all whom it may concern Be it known that I, LOUIS K. TIIORSIECK, a citizen of the United States, residing at Casco township, county of Allegan, State of Michigan, have invented certain new and useful Improvements in Metal Vheels, of which the following is a specification.

This invention relates to improvements in metal wheels.

The objects of this invention are: First, to

improve the structure of such metal wheels generally. Second, to provide an improved spoke structure. Third, to provide improved means for retainingthe spokes in p0- Fourth, to provide improved means of retaining the outer ends-of the spokes in conjunction with the rim. Fifth, to provide an improved hub structure. Sixth, to provide an improved rim structure.

Further objects and objects relating to details and economies of construction and op:

eration will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification- The invention is clearly defined and pointed out in the claims. I

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is an elevation view of a wheel embodying the features of my invention. Fig. II is an enlarged detail longitudinal sectional view through the hub taken on a line corresponding to line 22 of Figs. I and III. Fig. III is an enlarged detail view of the structure in process of construction with the hub portion in section, taken on a line corresponding to line 3-3 of Fig. II. Fig. IV is an enlarged detail elevation'view of the hub blank 4 before it has been folded and formed into the wheel, the blank part being characteristic of'both hub plates. Fig. V is an enlarged detail sectional view taken on a line corresponding to line 5-5 of Fig. IV, showing the form of the blank. Fig. VI is a similar enlarged detail sectional view of the blank appearing in Fig. V, partially formed. Fig. VII is a similar detail sectional view showing the blank completely folded and formed; Figa VIII is an enlarged detail transverse sectional view through the r m portion in process of formation, taken on a line corresponding to line 88 of Fig. III. Fig. IXis a similar detail sectional view on line 99 of Fig. I showingthe rim conformed to embrace a half round tire. Fig. X is a similarview of a modification of the structure showing a round rubber cushion tire. F igQXI is a modification in which a flat rim is provided.

In the drawing similar numerals of reference refer to similar parts throughout the several views, and the sectional views, etc.

Considering the numbered parts of the drawing, the rim 1 is of metal suitably per,- forated and grooved and may be produced eitheriby stamping or by rolling and welding, or the like.

2 is the hub barrel, having an outturned flange 3 with serrations at one end anda reduced portion which is expanded into a flange 3"at the other end. A separate hub plate 4 is formed with a tubular extension 5 at the center, which is toothed with ratchet shaped teeth 5 as clearly appears from an inspection of Figs. II and V. This flange is perforated at 6 and is formed asindicated in F ig, IV. The plates have extensions 7 which wrap around. the inner ends of the spokes. The flange is perforated at- 6 at intervals, as clearly appears in Fig. IV, through which the doubled spokes 8 extend, the same being folded at the center somewhat like a hair pin. After the same have been folded, the extensions 7 are wrapped.

around the same as seen in Fig. II and as illustrated in detail at Fig. VII. A short piece of rod 10 is placed within the angle of the spoke pieces so that it extendsstraight through the perforation 6 in thehub plate 4:, making a very secure and strong joint at that place, and Without undue strain upon the metal at the point of perforation. The outer ends 9 of the spokes are cut in half and serrated, so that they are engaged the one within the other forming substan tially a continuous wire where the parts are brought into juxtaposition, as seen in process of manufacture in Fig. III. The spokes are bent at 8", 8", (see the left part of the Fig. III where the ends 9 are brought together). In the right hand port-ion of the figure the parts are in process of manufac- Patented May 5, 1914.

ture, the ends9 being folded down and partly brought'together in the process there indicated, When they are brought down together, the narrow groove 14 of the rim is wrapped and closed around the same, the rim being perforated at 15 to receive the outer ends of the said spokes. The same is then folded and clamped around the spokes and the outer portions 16 are folded upon themselves, as appears in Fig. IX and embracethe edges of a half round cushion tire 17.

A hub flange 11 is providedxwith a suitable tubular extension 12 to slip onto the reduced portion of the hub 2, and is folded upon itself precisely in the manner indicated for the hub fiange 4, the same being folded down at 13 corresponding to the fold 7. The spokes are precisely the same. These parts are forced into position and the part 3 expanded to retain the same efi'ectively in position.

In the modification of the rim, the outer portion is turned up at 16 to receive a round cushion tire as clearly appears in Fig. X. These portions may be out flat at 16 without any cushion tire of any description.

From this description which I have given it will be very clear that this wheel is a very strong wheel, very simple to manufacture, and is very artistic in appearance when completed, with perfectly straight spokes without any exposed uneven parts, and yet the spokes are effectively retained in place and cannot be removed without substantially destroying the entire wheel. There are no rivets or screws in the entire structure. The retaining means which locks the entire Wheel together is the expanded portion 3' at the hub. The outer ends of the spokes are most effectively retained within the groove'and owing to their toothed ends cannot be displaced and thus greatly strengthen the rim of the wheel.

I desire to claim the invention specifically as well as broadly, as, clearly appears in the appended claims.

Having thus described my invention,what I claim as new and desire to secure by Letters Patent is:

1. In a wheel the combination of a hub; doubled spoke pieces, the outer ends of the same being cut in half and serrated to conform and engage the one upon the other; and a sheet metal; rim perforated and grooved at the center so as to receive the ends of the overlapped spokes within the groove, all coacting substantially as described and for the purpose specified.

2. A wheel comprising a hub, metal spokes,.and a rim, the ends of the spokes be ing arranged through the rim and turned laterally and overlapped in pairs, the overlapped spoke ends being flattened and serrated, the rim containing a trough-shaped recess extending around its surface the walls of the trough being bent inwardiy toward each other to clamp the overlapped ends of the spokes together.

3. A wheel containing metallic spokes, and a metallic rim containing a troughshaped recess extending around its surface, the spokes having laterally turned ends passed through the rim and engaged in the bottom of the trough, the ends of adjacent spokes beingoverlapped and flattened and serrated and held in position by being engaged by the walls of the trough which are bent toward each other until they are closer together than the diameter of the looped spoke ends.

4. A wheel comprising a rim containing a trough-shaped recess extending around its surface, a hub, and spokes having ends disposed approxlmately at right angles arranged through the rim and engaging the bottom of the trough, the ends of adjacent spokes being overlapped, the overlapped portions being serrated, the overlapped ends being engaged by the walls of the trough which are closer together than the diameter of the spoke ends. I

5. A wheel containing metallic spokes, and a rim, the spokes having ends disposed approximately at right angles to the spokes in a trough-like recess in the rim and engaged by the walls thereof which are closer together than the width of the spoke ends, the ends of adjacent spokes being overlapped and provided with inter-locking parts.

6. A wheel containing metallic spokes and a metal rim, the spokes being arranged through the rim and having ends disposed approximately at right angles to the spokes in a trough-like recess in the rim, the ends of adjacent spokes being ovelrlapped and provided with inter-locking parts, and means for clamping the overlapped spoke ends together.

7. A wheel comprising a hub, doubled spokes secured at their doubled ends to said hub, one-half of the spokes being secured at each end of the hub, and a rim containing a trough-shaped recess extending around its surface, the ends of the spokes being arranged through the rim and bent laterallv into the bottom of the trough with the ends of adjacent spokes overlapping, the overlapping spoke ends having interlocking portions and being engaged by the walls of the trough, which are closer together than the diameter of the overlapped spoke ends, one spoke of each coengaging pair radiating from each end of the hub.
