MECHANICAL BELTIN'G.
Application led Hay 29, 1923. Serial No. 642,232. .i
To all 'wlw/m.' it may concern;
` Be it known that I, HENRY B. COBB, a citizen of the United States, residin in the city of` Richmond, county of enrico, State of Virginia, have invented certain new and useful Improvements in Mechanical Belting, of which the following is a full, clear, concise, and exact description.
The objects of m invention are to generally improve mec anical belting for various purposes used in manufacturing in power plants, such as conveyer belts and belts used for the transmission of power.
Une of the specific objects of my invention is to produce a belting which will not stretch when placed under tension, and which will be of maximum strength possible to obtain from the quantity of the material used in its construction.
A further object of my invention is to produce a belt which, when used for conveyer urposes, will accurately conform to the s apes of the pulleys over which the belt passes, and will easily maintain a concave or trough shape thereby retaining the material being conveyed effectively on the surface of the belt. v
A further object of my invention is toA produce a belt the surfaces of which are without substantial interstices or recesses, thereby reducing the wearing elect on each of the strands and increasing the friction or adhesion with the pulleys over which the belt passes when used for power transmission purposes.
A further object of my invention is to produce a belting in which the tension strands or the strands by which the power is actually transmitted or the weightof material carried, is protected by outer lay* ers of strands so that the strength of the belting is not weakened as the necessary wearing progresses.
A further object of my invention is lto produce a beltin'g which may be made of material easily obtained in the market without ythe preparation of special kinds of yarn or cords.
For a detail description of one form of my invention which l at present deem preferable, reference may be had to the following specification and to the accompanying 'drawing forming a part thereof, in which- Fig. l is a plan view of a small section of a completed belt showing substantlally lower end of the belting shown in Fig. 2.
In the form of the belt illustrated in the figures of the drawing, numeral 1 indicates a series of parallel longitudinal cords or,
warp strands. These strands may' be of any referred type, such as braided strands simi ar to sash-weight cords@ or may be strands manufactured in the manner of the so-called Silvertpwn cords of. the Silvertownautomobile tires. Obviously, be in the form of ordinary twisted cord or rope, but should be preferably made in such a manner that the stretch or elongation under tension is a minimum.
These longitudinal strands l are unitedby a 'series of transverse cords or weft str` nds 2, 2b, 2, etc. ln the form of my invention illustrated in the gures of the drawing, these weft strands 2B, 2b, 2, etc., are perfectly applied as follows: The strand 2a of 'Fig 2 is looped or wound helically about the first two longitudinal or warp strands 1, whilethe strand 2b is looped or wound helically about the second strand of the lirst longitudinal pair and around the third of such strands, the successive convolutions of vthe strand 2b passing between the successive longitudinal warp strands 1 have'only onehalf the number of spiral convolutions binding them with their adjacent strands. `This fact would cause the convolutions of the strands 2a and 2 to be slightlyl separated they may I starting at the top by spaces equal to the thickness of one' as bove described is ,manufactured it mg a d s1on `strands and transverse blndmg loo s of transversestrand. To overcome this possible objection, I apply to the outer longitudinal strand 1 separate spiral strands 3 and 3" which engage said longitudinal strands only. These strands will lill the spaces above referred to and reduce the symmetrical elfact illustrated in ig. 1, by making the entlre surface of both sides of the belt continuous and smooth. These outer spiral strands 3 and 3b may, of course, be applied b means of separate shuttles in the machine or manufacturin the belt.
It will appreciated that when the beltmay be treated with a suitable compoun for lling in between or impregnating the' fibres of the material, whencotton, hemp, or other materials adaptable to this type of belting are used in its manufacture. The belt, when com leted, may be friction coated and cured in t e usual way familiar to the manufacturers of rubber goods, or the strands or fibres may be impregnated with rubber or other compounds prior to being Woven into the belt.
It will be noted from a consideration of the figures of the drawing that the transverse or weft strands engage the longitudinal strands in the manner similar to the engage-- ment between the 4plates or tongues of a hinge andthe pivot pins. This allows a large amount of transverse flexibility in thebelt which permits it to conform easily. to the surfaceof the driving or supporting pulleys over which the belt may run. ur-
- thermore, the longitudinal or warp strands vnecessary to cut out are always maintained parallel and in substantially strai ht lines instead of being woven up and own or in and out between or among the transverse strands. This fact eliminates the stretching of the belt owing to the straightening out of the warp strands under tension when woven in the usual way, and thereby produces a great saving in the length of belting'required for a particular 'pur ose. Heretofore, in using belting woven 1n t e usual way, it often has been found thirty feet or more of the belting in order to take up the slack,
thereby causing an unnecessary waste of ex'- pensive material.
Other advantages of my improved belting will be obvious from the manner in which it is made, and will be found to exist in practical use, in accordance with the objects of the invention above stated. a
Although it is obvious that the belting above described may be woven by hand in a suitable apparatus employing s uttles, yet I contemplate, as is usual in the manufacture of belting, to employ an automatic power driven loom which will produce the belting ra idly and economically. For this purpose I- ave devised such an apparatus or loom (part of the present flexible material, the longitudinal stran s being substantially straight, and said binding loops ybeing arranged 1n successive convolutions about a plurality of said lon itudinal strands which are bound together 1n successive transverse groups.
2". Belting, comprising longitudinal tension strands and transverse binding loo s of flexible material, the longitudinal stran s being substantially straight, and said bindin loops being arranged in successive helica convolutions about a plurality of said longitudinal strands which are bound together 1n successive transverse groups, the binding loops of the successive transverse groupsoverlap ing each other.
3. Be ting, comprising longitudinal tension strands and transverse binding loo s of flexible material, the longitudinal stran s being substantially straight, and said bindin loops being arranged in successive helica convolutions about a plurality of said longitudinal strands which are bound together in successive' transverse groups, the binding loops of the successive .transverse groups being relatively staggered and overlapping each other.
