TRACTION SHOE.
Application filed December 19, 1921.
To all whom it may concern:
Be it known that I, FERDINAND H. Hanan, citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Traction Shoes, of which the following is a spec-1- fication.
The present invention has to do with trac:
tion devices of the endless type, and useful for sustaining the weight or load of large bodies, such as machines, and rendering the latter portable when the traction devices are operated.
Such traction devices are made up of a plurality of shoes connected together and forming a sort of endless chain or belt passing around tumblers or sprocket wheels. This invention comprises a special construction of shoe designed with a view particularly to obtaining an exceedingly light structure but one having a maximum of strength and rigidity. In the carrying out of the invention, I utilize a cast body for the shoe,
1i ht in weight, a covering plate being ap plled to the bottom of the body and the cored out portions being strengthened by webs or ribs reinforcing the plate or covering member against inward displacement. The body is so made as to provide a driving lug or tooth centrally thereof, relatively staggered pivot lugs at certain opposite edges for pivotally connecting the sections of shoes together, and a flat inner or :top surface forming tracks or ways with which certain bearing rollers, forming a partof the traction unit, are adapted to engage.
The preferred exemplification of my invention is illustrated in the appended drawings, in which:
igure 1 is a top plan view of one of my shoes.
Figure 2 is an end elevation.
Figure 3 is a side elevation of two of the shoes in connected relation, one of them being broken away and shown in section to bring out its hollow body construction.
Figure 4 is a perspective view of the bottom tread plate or closure.
Specifically describing my invention, it is notable that my shoe is of very simple construction. The body 1 of the shoe is transcored out beneath the same to render it,
Serial No. 523,515.
versely elongated and is provided at its front and rear edges with the pivot lugs 2. These lugs are staggered in respect to the relation of those upon one edge and those on the other ed e of the shoe, as seen best in Figure 1. entrally of the body 1 is the driving lug or tooth 3, the same being of somewhat ta ered construction and being adapted to ht between driving portions of a tumbler or driving wheel, not illustrated.
Portions of the top or inner surface of the shoe at opposite sides of the lug 3, and designated 4, are relatively fiat and form tracks with which are adapted to engage bearing rollers and bearing surfaces of the tumblers, the said rollers also not being illustrated.
At opposite transverse extremities of the shoe the body is slightly curved upwards from the bottom or outer side, as shown at 5. The said body 1 of the shoe is largely of hollow formation as shown at 6 and likewise the lug 3 is hollow as shown at 7. This construction is designed to make for lightness and econom of. metal. Transverse webs 8 and longitudinal webs 9 separate the hollow portion of the shoe into a number of diflerent chambers or cavities and ac complish the additional function of rendering strong and substantial the hollow construction utilized for said body.
In order to prevent dirt and other foreign matter from enterin the body 1, and to provide a flat tread surface for the shoe, a tread plate 10 is applied to the outer or bottom portion of the shoe so as to cover the cavities or chambers at 6 and 7, and suitable screws, rivets or like fastenings shown at 11 pass through the body of the shoe and through the plate 10 firmly uniting these. parts together.
Structurally speaking, the design of the shoe as presented above affords a stout body and top compression member, plate 10 constituting a tension member, and the whole structure as a unit is one employing a minimum of material and having a maximum of strength and lightness. On this account the cost of the shoe as an article of manufacture is reduced materially in the making thereof, and since the cavities 6 and 7 and the holes for the fastenings 11 are cored, there is no machine work necessary upon the unit. As shown in Figure 3 several shoes are assembled with a pintle or hinge pin 12 connecting them at the front and rear ends, so that the shoes are quite flexible, something necessary in order that they may constitute a flexible traction unit once assembled. Furthermore, the pivot lugs 2 fit snugly together and do not allow material dropping upon the traction devices to pass therethrough. The webs 8 and 9 reinforce the plate 10 effectively, being engaged with the inner side of the latter as will be obvious from the drawings. At the side extremities of the shoe the openings for the fastenings 11 are somewhat inclined for obvious reasons.
The pivot lugs 2 are so arranged that the shoe is interchangeable so far as its connections with adjacent shoes are concerned;
' that is it makes no difference which set of lugs, either those at one edge of the shoe or the other, are presented for connection to the next shoe, so long as the shoe of course is right side up.
Having thus described my invention,- what I claim as new and desire to secure by Letters Patent is:
1. A traction shoe comprising-a relatively narrow long body having at its front and rear edges pivot lugs integral therewith, said body being closed at its inner or upper portion and of hollow formation so that it is open at its lower portion, and the pivot lugs being substantially in the plane of the body, the said inner or upper portion of the body being formed with downwardly extending reinforcing webs having a vertical arrangement and terminating adjaoent to the open lowermost portion of said body, and a cover plate attached to the body and of relatively thin format-ion and arran d so as to close the open lower portion 0 the body and to abut with the reinforcing webs as to be braced by the latter, and the body being equipped with a driving member to ('o-operato with a driving tumbler or sprocket.
2. A traction shoe comprising a relatively narrow long body having at its front and rear edges ivot lugs integral therewith, said body b6111 closed at its inner or upper portion and of hollow formation so that it is open at its lower portion, the said inner or upper portion of the body being formed with downwardly extending reinforcing webs havin a vertical arrangement and terminating'a jacent to the open lowermost portion of said body, and a cover plate attached to the body and of relatively thin formation and arran ed so as to close the open lower portion 0 the body and to abut with the reinforcing webs as to be braced by the latter, the said body at its upper closed portion being formed with an integral upwardly or inwardly extending lug of hollow formation and reinforced by one of the reinforcing webs aforesaid and having its hollow portion leading into the hollow portion of the body.
