WILLIAM A. LOUDON, OF CHICAGO, ILLINOIS.

WbiEEL-TlFIE= Application T (1, whom it may concern:

Be it known that I, TN'ILLIAM A. Lennon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi nois, have invented a new and useful Wheel- Tire, of which the following is a specification.

My invention relates to improvements in wheel-tires in which a plurality of blocks of fibrous material, preferably wood, are ar ranged circuinferentially around the wheelfelly or iron tire, and relates particularly to the manner of fastening the blocks to the wheel and to the arrangement of the blocks on the wheel; and the objects of my invention are,'first, to rovide a good traction-surface; second, to urnish a cheap, simple, and durable tire; third, to facilitate the easy and quick repair of the tire, and, fourth, to pro: vide a plurality of rows of blocks side by side circumferentially arranged around the wheel. I attain these objects by the construction illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a wheel embodying my invention. Fig. 1 is an edge view of the same. Fig. 2 is a side elevation of a fragment of the wheel shown in Fig. 1 on an enlarged scale. Fig. 3 is a section of Fig. 2. Fig. 1 is an elevation of the inner faces of the segmental plates as they appear when attached to a wheel. Fig. 5 is an elevation of one form of clamping-ring used to secure the tire on the wheel. Fig. 5" is a side elevation of another form of clamping-ring used to secure the tire on the wheel. Fig. 6 is a perspective view of one of the wooden blocks detached. Figs. 7, 8, and 9 are cross-sections similar to Fig. 3 of modified forms of construction. Fig. 10 is a fragmental longitudinal section through a wheel-rim, showing a modification; and Fig. 11 is a perspective view of still another modification.

Similar numerals refer to identical parts throughout the several views.

The wheel 15 consists of the ordinary hub 16, spokes 17, and felly 18, around which. is fitted the iron band or tire 19. Resting against this iron band are the blocks 20,which I at present consider best to be made of wood, but may be of any material. The blocks are substantially square in cross-section, one end of each block resting against the iron band 19 and the other end of each block extending out radially, subjected to the traction wear. To attain the necessary width of tractionsurface, I provide a plurality of cir- Fatented Feb. 13, 1905.

E cuniferential rows of blocks, which is one of the features of my invention. Another feature of my invention is to have the ends of the blocks resting against a flat iron band, thus presenting a firm even surface for the blocks to abut against and making the blocks all interchangeable, so that a block taken from a supply on hand can be inserted wherever a block has been worn away or displaced. The blocks 20 can be secured in their position by any suitable means. I have shown what I at present consider best adapted for the purpose. I prefer to have the iron band 19 integral with a side clamping-ring 21 as seen in Figs. 3 and 5, forming substantially a T- shaped iron band. A'portion of the ring 21 rests against the side of the felly 18 and a portion clamps the blocks 20 in a manner to be described. The outer edge of the ring 21 is peened over inwardly, as at 22, to insure better contact with the adjoining blocks. On the opposite side of the felly I provide segmental clamping plates 23, which when placed in position side by side form a ring similar to the ring 21, and they have their outer edges peened inwardly, as at 24, to insure better contact with the adjoining blocks. A groove or recess is preferably provided on the inner face of the plates 23, into which fits the band 19. 21 and the plates 23 against the blocks 20, a bolt 26 is provided, preferably passing adjacent to the iron band 19, the base of the blocks being partly cut away to permit of such passage of said bolt, with its head on the outside of the ring 21 and its nut on the outside of the plate 23. Asufiicient numberof bolts 26 are used to securely hold the parts together.

The two outer rows of blocks 20, which are adjacent to the ring 21 and the plates 23, are engaged. b the inner faces of such ring and plates an by their respective peened-over

edges

22 and 24 and are thus absolutely prevented from displacement. To prevent the displacement of the intervening rows of blocks 20 and to hold the same in position, I provide the clenching-rings 27 between the rows of blocks. Each ring 27 is provided on its periphery with a bead or lateral projecting rim 28, which impinges the adjacent wooden blocks when the nuts are turned on the bolts 26 to force the rows of the blocks together. The rings 27 serve as washers between the rows of blocks and fit loosely over the band 19 and are cut away sufficiently to permit the free passage of the bolts 26.

To securely clamp the ring To assemble the parts, the band or tire 19, with its integral ring 21, is secured around the felly 18 of the Wheel in the ordinary manner. Then the wheel being preferably laid fiat with the ring 21 downward, the bolts 26 are inserted through the holes provided for the same in the ring 21. N ext the first row of blocks 20 is laid around the band 19 on the ring 21. Then the first clamping-ring 27 is slid over the band 19 and laid on the first row of blocks. Next another row of blocks 20 is laid around the band 19 on the clamping-ring 27, and so on, alternating a row of blocks 20 and a clamping-ring 27 until the whole Width of the tire is complete. Of course the width of the tire is predetermined, so that a certain number of rows of blocks and rings will just fill the space between the ring 21 and the plates 23. The blocks 20 may or may not have the grooves 29 cut therein to receive the

portions

22, 24, and 28. Finally, the segmental plates 23 are laid into position, and the nuts are screwed tightly upon the bolts 26, thus clamping all the blocks between the ring 21 and the plates 23.

In Fig. 7 is shown the ordinary construction of the wheel having the folly 18 surrounded by the iron tire or band 19 and my invention applied thereto by providing a separate ring 21, having the peened-over edge 22, on the one side of the telly and the segmental plates 23, having the peened-over edge 24, on the other side of the felly. In this construction I prefer to use the additional bolts 30, passing through the folly, besides the bolts 26 to clamp the blocks 20 between the ring 21 and the plates 23. I have also shown in Fig. 7 that instead of using the flat washer-like rings 27 I may employ the rings 31, which do not contact with the band 19, but simply rest against'the beveled ortion of the adjoining sides of the rows of b ocks, and thus prevent any radial displacement of the blocks 20.

In Fig. 8 is shown a wheel having its felly 18 surrounded by a tire or band 19, having integral therewith the two clampin -fianges 32, which substantially correspon to the ring 21 and plates 23 in far as that portion 20 are clamped is concerned. The clamping flanges 32 are provided with the peened-over edges 33, similar to the

edges

22 and 24, previously referred to. In'the construction shown in Fig. 8 the blocks 20 are clamped in position and prevented from any radial displacement by small rods or cables 34 being forced in against the beveled adjacent sides of the rows of blocks, any convenient means (not shown) being provided to shorten the rows or cables 34.

Figs. 9 and 10 illustrate one mode of ating my tire to a metallic wheel. The rim the Wheel being metallic has tach .19 of integral l therewith the clamping flanges 32. The blocks are arranged in rows and are clamped into position by the bolts 35, which have their screw-threaded endsprojecting through the iron band or rim 19 and their other ends terminating in wedge-shaped bars 36, which are arranged to slightly overlap at the ends, as shown in Fig. 10, and contact with the beveled portion of the adjacent sides of the rows of blocks and tend to separate the rows of blocks when the nuts are turned on the screw-threaded ends of the bolts 35, thus wedging the blocks tightly between the flanges 32, against which the two outer rows of blocks rest.

It is obvious that the wooden blocks 20 could, if preferred, be secured to the metallic wheel by having only one of the flanges 32 integral with the rim 19 and segmental plates to take the place of the other flange with a number of bolts connecting the flange with the segmental plates, substantially as shown in Fig. 3, or the wooden blocks 20 may be secured to the metallic Wheel by having a separate clamping-ring on one side of the rim 19 and the segmental plates on the other side connected by bolts, as shown in Fig. 7. It is also to be understood that I may use any means for holding the blocks in position and from being displaced radially; but I prefer using some one of the constructions shown. So long as a plurality of rows of blocks are secured to the periphery of a wheel, no. matter what means are used for securing the same in place, the construction is within the meaning and scope of my invention, providing, however, that such blocks are capable of being removed separately and of being replaced by new blocks. I

In Fig. 11 is shown still another modified formof constructin blocks on the periphery of a wheel, each Iflock 20 being tapered slightly and inserted in a collar 37, which is secured to the rim 19 of thewheel by bolts or screws passing through the cars 38.

y my improved wheel-tire the wearingsurface is wood or other material, if prefer able, and is capable of being removed and re-' placed in small sections. The great advantage of this construction is to provide a cushion-tread and means whereby when a certain portion of the tire becomes damaged only that portion of the tire which is damaged need be replaced, thus making use of every portion of the tire until it is worn out.

I am aware that previous to my invention wooden tires have been used and do not claim the idea of usingwood for tires broadly; but 2 What I do claim, and desire to secure by Letters Patent, is
