Patented Apr. 14, 1931 UNITED-STATES PATENT orFicE JOHN LCABIPODONICO, OF STOCKTON, CALIFORNIA, ASSIGNOR T SER-AFINO PAULINO,
' OF TIBURON, CALIFORNIA, AND MODESTO E. ESPOSTO, OF SAN FRANCISCO, CALI- FORNIA, A S JOINT TE-NANTS TRACTION WHEEL Application filed May 23, 192?. Serial No. 193,427.
7 This invention relates to traction wheels of the type shown in my former patent entitled Tractionwheel, Number 1,370,409, is sued March lst, 1921 and particularly to improvements on the link connections formed between the shoes and the wheel.
In the form of structureshown in the patent, above referred to, two links were required inconnection with each shoe, onelink would 10 be placed in tension and form the driving connection between the wheel and the shoe when drivingaheaid and vice versa the other link wouldbe placed under compression when the wheel was reversed. This arrangement, of
course, doubled the number of links required,
, it increased weight, wear and tear and the cost of manufacture and repairs. The links were, furthermore, spaced apart and disposed one on each sideof the shoe. This was I also found to be detrimental as a twisting movement or side-thrust was created when driving, which further increased wear.
The object of the present'invention is to 1 generallyimprove and simplify the construction and operation of thelink connections of the character described; to provide a single link between the wheel and shoe, so connected that it may be placed in tension or compression and as such will serve as a driving connection when driving ahead or reverse; to'
provide a link connection which will positively prevent slippage between the wheel and the shoes and further to provide a link connection in which twisting-space or side-thrust is entirely eliminated. a
One form which theinventionmay assume isshown by way of illustration in the accompanying drawings, in which Figure'lis a sectional view of a portion of 40 a traction ,wheel showing the application of th sh es,
F-igure12 is a cross sectiontaken on the line I 1'II o Fig r 1,
. Figure 3 isa s c q a ew im lar o gure 1, hut showing a modified formof link onn ction, y
' F igure 4 is a similar section of Figure .1,
. sect on,
,showing another modified form of lifnkdcon- j members 9 and 10.
Figure 5is a'd-iagrammatic view showing Extending cross-wise of the shoe, interlarly Figures 1 and 2, it will be noted that only a portion of the rim of a traction wheel s lllustrated. This is due to the factthat any standard form ofhub structure, spokes etc., may be employed. The rim is, in thid instance, indicated at A and it is supported by a circular disc B in the manner of disc wheels. Secured on the exterior periphery of the rim are continuous annular flanges as indicated at 2, 3, 4 and 5 and held in engagement with the flanges are a plurality of shoes generally indicated at C.
These shoes form a flexible track for the wheel whether it rotates ahead or reverse and the invention, in this instance, is particularly directed to the driving connections formed between the rim and the shoes.- The shoes are elongated and are rectangular in shape. They are all identical in construction and the description of one shoe and its connection with relation to the rim of the traction wheel should, accordingly, suffice. The shoe consists of a tread section '6 on the outer face of which is formed grousers or like flanges such as indicated at 7 and 8. On the inner surface are formed a pair of track members 9 and 10 and intermediate the track members are formed segmental sections, such as indicated at 11 and 12.
These segmental end sections are disposed at opposite ends of the shoe and they project upwardly or inwardly through the rim,
openings suchas indicated at 14 and 15, being formed in the rim to receive the segmental sections. The segmental end sections are shown in my former patent referred to and serve the function first of limiting" the rocking movement of the shoe with relation to the flanges 2, 3, 4 and 5 and secondly of securing the shoe against twisting or lateral movement so that alignment will be maintained between the flanges and the track terspaced flange rings thereon, a shoe exterior of the rim, interspaced track members on the shoe aligning with and engaging the ring flanges on the rim, a single driving link between the shoe and the rim, a pivotal connection between one end of the link and the rim, said pivotal connection having its center on the line of contact between the ring flanges and the track surfaces on the shoe, and a pivotal connection between the opposite end of the link and the shoe, said pivotal connection being made at a point exterior of said line of contact.
3. In a traction wheelof the character described, a rim section, a pair of annular inter spaced flange rings thereon, a shoe exterior of the rim, interspaced track members on the shoe aligning with and engaging the ring flanges on the rim, a driving link between the shoe and the rim, a pivotal connection between one end of the link and the rim, said pivotal connection having its center on the line of contact between the ring flanges and the track surfaces on the shoe, a pivotal connection between the opposite end of the link and the shoe, said pivotal connection being made at a point exterior of said line of contact, and spring actuated means normally maintaining the shoe in contact with the ring flanges.
4. In a traction wheel of the character described, a rim section, a pair of annular interspaoed flange rings thereon, a shoe exterior of the rim, interspaced track members on the shoe aligning with and engaging the ring flanges on the rim, a single driving link between the shoe and the rim, a pivotal connection between one end of the link and the rim, a pivotal connection between the opposite end of the link and the shoe, said pivotal connection at one end of the link having its center on the line of contact between the ring flanges and the track surfaces on the shoe and the opposite pivotal connection being made at one side of said line of contact, said link and track members on the shoe having an equal length, and the length of the link and track sections on the shoe being equal to the length of the line of contact between the ring flanges and the track members.
