To 1f/ZZA whom it may con/cern: f

Be it known .that I, EMIL EINFELDT, of Davenport, county of` Scott, and State. of Iowa, have invented 'a new and useful Im.- provement inTractionWheels. of which the This invention relates to v and has reference more particularly to the form and construction'ofthe traction cleats,

and their vmanner of application tothe wheel 'c The invention consists in complementary cleats, embodying each a baseflange adapted to be seated and secured tothe rim'of the Wheel, and a vertical fiange or web toserve as a traction surface, the said cleats being so applied that the vertical flanges or webswill conjointly forma continuous and uninter-v ptedl traction surface extending zigzag. around the-rim.

The invention consists also in the details of I construction andV combination of parts hereinafterl describedandclaimed.

' In the laccompanying drawingsa-Fil l is a side elevation of a portion of a w Fig. 2 is a top plan view of the samepartly in section. Fig.-'3 is a transverse section on.

theline a-a of Fig. `2. Figs. 4 and 5 are side elevations of two of the cleats detached,y showing their relative formsby which theyl are adapted to coperate in accordance with' my invention. Fig. 6 is a planview of a portion ofthe rimI of a wheel, showin ,the traction cleats applied in a modified an different manner.

Referring to the drawings:-#1`2,j3, etc., represent my improved traction'cleats each in the form of a length of commercial vangle steelha'vinga base flange A and anupright web or flange B, the base flange being adapt-- ed tolrest on and be secured to the of the wheel, while the uprightdlange serves as a l'-trac1'.-ion rib or surface. These cleats are ap- 'plied to the, rim in' such manner and-in such .relative arrangement, ,that conjointly: the vertical flanges will :present an uninterrupted i and continuous 'traction rib or'.l surface `extending 4zigzag around`.'the lw'heelrim.` As

"shown, the cleats extend' obliquely at relative angles, the base, flanges being overlapped v 1 ofthe cleats', each cleat has its "in order that the-vertical flange of one cleat may be brought close, up'to and form an angular continuation ofthe vertical e-of the next cleat.` In theoverlapping of t e ends traction lwheels,

asefflange at.

fone end overlying -the base flange of one of its adjacent cleats, while the opposite end of its base flange underlies the base flange of its 'other adiacent cleat. This arrangement is clearly illustrated in Fig. 2, Where it will'be -seenwthat the forward end (assuming fonthe purposes'of. description that the wheel is traveling to the right) of cleat `2 rests-upon and overlies the real; end 'of cleat 3 in advance, while the rear end of cleat 2 underlies and extends beneath the forward end of cleat '1 at the rear. A

In order that in the arrangement described the upper edges of the vertical flanges will vvbe,

on the same level, that is flush with eaxli" the ends, I form the base flange of each cient side to receive .the' base flange 'ofthe cleat uplon which it is seated, the result .being n that W en the cleats are assembled and the blend or socket portion of each. rests on. the base fla e of the\next cleat, the n per edge ofthe vertical fiange of the sockete cleat willbe at the same-u level or flush with and will adjoin the u per edge of the 'vertical .flange of the `next c eat. This construction is clearly'r illuswhich they areassembled and cooperate on the rim *of the wheel; 'Anya a propriate means may be employed, such as hy the use of rivets, for firmiyattachingthe base fianges to the wheel rim, but I have shown and I prefer toutilize for this purpose, the vspokes of :the wheel, which are extended'througli the vof the'. cleats and headedfdown thereon to seyticularly in Fig. 3..-

Referring to Fig. 2, it be observed that conjointly by the upright flanges, extends a the vertical flanges intersect. This I contmted in Figs. s, und 5,v where if. win be and left, by reason. of the peculiar manner in Wli'eel rim and through the overlapping ends c ure the parts together, -as illustrated par' the continuous traction rib or'surface formed.

other, notwithstanding the overlappingnf c at one end 'with a socket or bend in its under A IOO IIO

slight distance outward at the points where Sider desirable feature, in that the tractive effect is increased. In order that this effect may be more pronounced, the construction vshown in Fig. 6 may be employed, Where. it Will be seen that the cleats are extended. be-

yond their points ofintersection nearly to the edge of the rim.

' While I prefer to form the socket or bendl in the base flange of the cleat, in order to preserve the same height or level of the traction surface as described, it Will be'understood that this'is not essential, for good ref sults may he obtained by omitting these depressions and forming the traction cleat of the same crossesectional form throughout.

. Furthermorait is not absolutelyessential although preferable, that the cleats be` arranged rightand left in themanner shown, because good results'may be obtained by other arrangements provided that the trac.

tion surface formedl conjointly by thevertical 'flanges Will extend zigzagvand continuously around the Wheell rim. l Having thus described my lnvention, what I claim iszl.' In combination Withya Wheel rim, trac-- tion cleats eachcomprising a base flange andan uprightflange, said cleats extending diagonally With their base flanges overlapping at the endsfand fastened to the rim `of the Wheel. i

' 2L In combination with a wheel rim, traction cleats, each comprising a base flange and an upright flange, said cleats'extendingl di- .agonally with' the end of'the base flange 'of and having the other end of its base flange lextended beneath the base flange of its other ries of traction cleats appliedl thereto and I adjacent cleat. j l

4. In comblnatlon with a Wheel rim, a se-` each comprising a baseflange and an upright flange, said cleats extending .diagonally and each having its base flange formed lin its uni der side at one end ywith a socket or bend adapted to 'receive the base flange of the adjacent cleat.

5. In combination with a wheel rim, a series of' traction cleats applied thereto diagof nally, and each comprising a base flange and an upright flange, the baseflanfy of one cleat being seated at one end on the Ivase flange of one of its adjacent cleats, and extendin at its oppositeend beneath the base flange o its other adjacent cleat, and each of sait cleats, where it underlies theend of the other, being extended beyond the point of intersection.

6; In combination with a Wheel rim, 4a series of traction cleats applied thereto diagonally and each comprising a base fiange rest ing on the Wheel rim and an upright flange, each cleat being seated at one extremity on the hase flange of the next cleat, with its end albutting againstthe upright flange of said c eat. l

v7. In combination with thevhub, s okes andi-im, traction cleats applied diagona y to the rim With their ends overlapping,the saidv spokes being extended outward through the rim and through the overlap ing vends of the cleats and acting to secure tli place. 4

8. In a traction Wheel, a series of' complementary traction A'cleats or elements, each comprising a base flange adapted to rest on and be secured to. the rim of the Wheel, and

an upright flange ada ted to form a traction rib, a portion of said c eats having a socket or bend formed 1n the base fiange at one end, and thel remalnder of fsaidcleats having a similar socket or bend formed in their hase'- flange at theopposite end.

In testimonyl whereof I hereunto set my hand this first day of November, 1906,in the presence of twoattesting Witnesses. l l i I ElvIIIi EINFELDT.
