Specification of Letters Patent. Patentd Jun@ 1LT, 19199 Application filed February 6, 1917. Serial N o. 146,886.
To all whom it may concern:
Be it known that I, STEPHEN D. HARTOG, a citizen of the United States, and a resident of the city of St. Louis, State of Missouri., have invented a certain new and useful Improvement in Vehicle-Tires, of which the following is a specification.
My invention relates generally to vehicle wheel tires and more particularly to a casing for pneumatic or inatable tires, the principal objects of my invention being to provide a compartively simple and inexpensive casing which is practically puncture proof; to construct a casing in sections or segments which have interlocking engagementwith each other so as to. maintain the completed structure in proper assembled relation, which sections can be readily assembled or taken apart; to construct the main body of each section of yielding resilient material, such as rubber, composition or fabric, and to embed therein a plate of metal or analogous material, the same serving as a shield to prevent puncture through the tread portion of the casing section or segment, and to provide the metal plate with a flange, which when the sections are properly assembled occupies a transverse position between an adj acentv pair of segments with the outer edge of said flange lying flush with the outer surface of the completed casing, thus in effect serving as a non-skid element and at the same time materially reinforcing the tread portion of the casing and tending to decrease the wear thereupon.
With the foregoing and other. objects in view, my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described,
claimed and illustrated in the accompanying drawings in Whichp Figure 1 is a side elevational view of a portion of a casing of my improved construction with a part broken away and in section.
Fig. 2 is a plan View of a portion of my improved casing with parts thereof broken away and in section.
Fig. 3 is a section taken through the center of one of the casing sections contemplated by my invention.
, Fig. 4 is a cross section taken on the line 4-4 of Fig. 3.
Fig. 5 is a plan view of one of the casing segments.
Fig. 6 is a plan View of one of the metal plates which is carried by each segment.
Fig. 7 is a section taken on the line 7-7 of Fig. 6.
Fig. 8 is an elevational view of one of the metal plates.
Referring by numerals to the accompanying drawings, 10 designates thebody of the casing section or tread segment contempl-ated by my invention, said body comprising a tread portion l1, side walls 12 and beads 13 all formed integral and composed of yielding and preferably resilient material such as rubber, rubber composition or the same in combination with fab-ric or suitable fibrous material.
The tread segments thus formed have a cross sectional contour corresponding to the accepted types of casings for pneumatic tires and may be made in any desired and practical length.
Embedded in each segment is a frame plate 14 preferably of meta-l, so as to form the frame or skeleton for the resilient segment, and so as to also form a puncture protector or puncture proof shield, the same being curved to correspond with the curvature of the tread portion of the segment. One edge of this plate is bent into a plane substantially at right angles to the body of said plate thereby forming an outwardly projecting flange 15 which lies directly against one end of the body of the segment and the edge of said flange lies flush with the tread surface of said segment.
The plate 14: is bent inwardly near its center to form an abrupt shoulder 16 and that portion 17 of said plate beyond this shoulder is concentric with the main body of the plate and necessarily has a smaller radius. Formed integral with the central portion of the member 17 is an outwardly projecting tongue 18, the outer portion of which is offset slightly with respect to the inner portion and formed in said offset outer portion is an aperture 19. A portion at the center of the member 17 is stamped or pressed downwardly to form an outwardly presented hook or tongue 20 the same occupying a horizontal plane slightly below the tongue 18. The plate thus constructed is embedded in the tread portion of the casing segment with the flange. 15 against one end of said segment and with the tongue 18 pro jecting from the opposite end as shown 1n 5 Fig. 3.
Formed in the center of the tread portion 11 of the segment and directly beneath the center ofthe metal plate is a recess 21 which is of sufficient width to accommodate the tongue 18 of the next adjacent segment. (See Figs. 3 and 4;.) Vhen the segments thus constructed are in proper assembled relation to form a casing they occupy the 'positions seen in Figs. 1 and 2 with the flanges 15 of the embedded plates fitting snugly between the ends of an adjacent pair of the segments, with the projecting tongue 18 of each segment inserted through the recess 21 of the next adjacent segment and with of said Vsegments toward4 each other with suficient force to compress the material of which the segments are formed to such a degree as to permit the tongue 20 to be passed through the corresponding aperture 19.
A casing of my improved construction is comparatively simple, can be easily and cheaply manufactured,`is puncture proc-f in its 4tread portion, is non-skidding in effect by reason of the flanges 15 which are located between the segments, and in the' event that any of the segments become worn so as to be unfit for service Ithey can be easily and quicklyremov'ed and replaced by new segments.
It will be noted that each tread section is provided with a frame or skeleton on which the rubber or resilient body of the section is built, and that these frames are connected or inter-locked in 'such a manner as to flexibly connect the tread sections. It will be understood, of course, that the tongues 18, being constructed of metal and being, therefore, yielding as well as resilient, and each tongue 5 extending into a recess in the adjacent casing sections, the necessary relative movement v lbetween the tread section is permitted. These frames, therefore, being connected and interlocked, form a chain around the casing 0 tread, 1thereby furnishing a strong frame chain as a skeleton or foundation with a resilient'body of necessarily weak material as i the tread. It will be moreover noted that these frames furnish an efiicient protection 65 or shield against punctures.
the tongue 20 of said next adjacent segment flexible material, and a puncture It will be readily understood that minor changes in the size, form and construction of the various parts of my improved casing may be made without departing from the spirit of my invention the scope of which is set forth in the appended claims.
