i E S T T 551 WILLIAM S. LANGFORD, OE BALTIMORE, MARYLAND.
BELTING.
Application filed October 21, 1922.
T 0 all whom it may concern:
Be it known that 1, WILLIAM S. LANGFORD, a citizen of the United States, and a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Belting, of which the following is a specification.
This invention relates to improvements in belting and has for its object the provision of stitched belting which will not stretch, unravel, or pull out of the lace holes when spliced, or break, which usually occurs due to a regularity of stitching.
A further object of the invention is the provision of a reinforced stitching for'belting in which the length of the stitches in adjacent rows are variable and in which the stitches of each row in the belting are located in staggered relation so that at no time. are the entering points of the stitches of the several rows arranged in a line running transversely of the belt but are in staggered relation.
Another object of the invention is the provision of a plurality of lines of longitudinal stitching for a solid woven belt, with the stitches of the various lines located in staggered relation whereby the tendency to transverse breakage of the belt is decreased.
Other objects and advantages of the invention will be apparent during the course of the following description.
The invention is illustrated by way of example in the accompanying drawings, in which,
Figure 1 is a plan view of a section of the belting showing the preferred form of stitches located in staggered relation.
Figure 2 is another form of stitching forming part of my invention.
Figure 3 is still another form of the stitching according to my invention for reinforcing belting.
Figure 4 is a transverse section of the belting shown in Figure 3.
Belting usually employed for commercial purposes may be of three standard types, such as,
(1). Rubber belting constructed from single layers of canvas or duck, treated with rubber, then laminated or folded to the required thickness and in some instances stitched and then put under pressure and vulcanized.
(2). Stitched canvas belting constructed Serial No. 595,987.
from cotton duck or other fabrics woven to the required width or thickness and then folded or laminated so as to form two or more plies, then stitched longitudinally or obliquely, with each stitch being of the same length. he stitched canvas belting is then impregnated with oils or gums, stretched and then painted.
Solid woven belting which is constructed from spun or twisted yarn such as cotton jute and camels hair, woven into solid form, the strands or layers of yarn amalgamating with one another until the required thickness is obtained.
Solid woven belting as is well known is only adapted for very light work since it stretches very readily when put under strain. unravels and pulls out at the lace holes when spliced.
The first two forms of belting have been stitched for locking the plies together but as far as I am aware no form of stitching has been employed on solid woven belting and it is to this form of belting that my form of improved stitching is adapted to be applied. Such stitching increases the life of the belting by preventing stretching, unravelling and tearing out of the lace holes and likewise prevents transverse breaking of the belting due to the irregularity of the positions of the various stitches forming each line of stitching.
' Referring to the drawings, 1 designates a solid woven belt which isprovided with a line 2 of stitching with the stitches each L of an inch long and an alternating line of stitching 3 with each stitch in said line approximately of an inch long. The lines of stitches are substantially placed 9; of an inch apart.
It will be noted in this form of stitching that none of the points 4, 5, 6, 7, and 8 through which the stitches. are passed are in transverse alinement but are located in staggered relation withv each other. An object of this form of stitching is to prevent weakening of the belting along transverse lines of the belting. Figure 1 discloses the preferred form of my invention.
A second form of my invention is disclosed in Figure 2 in which stitches 9 are longer than stitches 10. It will be seen that stitches 9 and 10 of each row are alternately disposed so that the. points 11, 12, 13, 14 and 15 are located out of transverse alinement so that the belting will not be weakened by a series of perforations extending transversely of the belt and in the same line.
The small stitch of one row of stitching shown in Figure 2, is located opposite the larger stitch in an adjacent row.
In Figure 3 is shown another form. of my invention in which the stitches 16 of one row are substantially of the same length, while the stitches of an adjacent row are alternately long and short. It will be seen that in this fornr, as well as in the other two forms, the stitches of the variousrows are always located in staggered relation. The length and position of the stitches gives the staggered relation of the perforations 18, 19,20, 21 and 22 of F igure'3. The staggering of these perforations will prevent breakage of the belt on a line which runs directly transversely of said belt.
Were the perforations through which ends of the stitches pass all located in transverse lines at right angles to the running length of the belt, the. stitches would cause a weakening of the belt along these lines and the belting would readily break at these portions. By staggering the stitches and likewise the penetrating points of the stitches, the direct lines of breaking will be dissipated with the effect of greatly increasing the life of a. belting.
What I claim is: I 1. A solid woven belting provided with a plurality ot' lines of stitching disposed longitudinally of the belting, the stitches of the several lines of stitching being of varying lengths, said stitchesinterlocking with first mentioned row, said stitches interloc ing with thewoven. elements of the belting and forming with the belting a unitary,
structure.
3. A solid woven belting provided with a plurality of lines of stitching disposed longitudinally of the belting, the stitches of the several lines of the stitching being of varying lengths with certain of the stitches in one row being longer than the stitches in an adjacent row with the stitches of one row located in staggered'relation with the stitches of an adjacent row, said stitches interlocking with the woven elements of the belting and forming with the belting a unitary structure.
